Alkali

In chemistry, an alkali (; from ) is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic al qalīy (or alkali), meaning the calcined ashes (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (slaked lime), a far more strongly basic substance known as caustic potash (potassium hydroxide) was produced. Caustic potash was traditionally used in conjunction with animal fats to produce soft soaps, one of the caustic processes that rendered soaps from fats in the process of saponification, one known since antiquity. Plant potash lent the name to the element potassium, which was first derived from caustic potash, and also gave potassium its chemical symbol K (from the German name Kalium), which ultimately derived from alkali. Common properties of alkalis and bases Alkalis are all Arrhenius bases, ones which form hydroxide ions (OH−) when dissolved in water. Common properties of alkaline aqueous solutions include: Moderately concentrated solutions (over 10−3 M) have a pH of 10 or greater. This means that they will turn phenolphthalein from colorless to pink. Concentrated solutions are caustic (causing chemical burns). Alkaline solutions are slippery or soapy to the touch, due to the saponification of the fatty substances on the surface of the skin. Alkalis are normally water-soluble, although some like barium carbonate are only soluble when reacting with an acidic aqueous solution. Difference between alkali and base The terms "base" and "alkali" are often used interchangeably, particularly outside the context of chemistry and chemical engineering. There are various, more specific definitions for the concept of an alkali. Alkalis are usually defined as a subset of the bases. One of two subsets is commonly chosen. A basic salt of an alkali metal or alkaline earth metal (this includes Mg(OH)2 (magnesium hydroxide) but excludes NH3 (ammonia)). Any base that is soluble in water and forms hydroxide ions or the solution of a base in water. (This includes both Mg(OH)2 and NH3, which forms NH4OH.) The second subset of bases is also called an "Arrhenius base". Alkali salts Alkali salts are soluble hydroxides of alkali metals and alkaline earth metals, of which common examples are: Sodium hydroxide (NaOH) – often called "caustic soda" Potassium hydroxide (KOH) – commonly called "caustic potash" Lye – generic term for either of two previous salts or their mixture Calcium hydroxide (Ca(OH)2) – saturated solution known as "limewater" Magnesium hydroxide (Mg(OH)2) – an atypical alkali since it has low solubility in water (although the dissolved portion is considered a strong base due to complete dissociation of its ions) Alkaline soil Soils with pH values that are higher than 7.3 are usually defined as being alkaline. These soils can occur naturally, due to the presence of alkali salts. Although many plants do prefer slightly basic soil (including vegetables like cabbage and fodder like buffalo grass), most plants prefer a mildly acidic soil (with pHs between 6.0 and 6.8), and alkaline soils can cause problems. Alkali lakes In alkali lakes (also called soda lakes), evaporation concentrates the naturally occurring carbonate salts, giving rise to an alkalic and often saline lake. Examples of alkali lakes: Alkali Lake, Lake County, Oregon Baldwin Lake, San Bernardino County, California Bear Lake on the Utah–Idaho border Lake Magadi in Kenya Lake Turkana in Kenya Mono Lake, near Owens Valley in California Redberry Lake, Saskatchewan Summer Lake, Lake County, Oregon Tramping Lake, Saskatchewan See also Alkali metals Alkaline earth metals Base (chemistry) References Inorganic chemistry

AMOS (programming language)

AMOS BASIC is a dialect of the BASIC programming language for the Amiga computer. Following on from the successful STOS BASIC for the Atari ST, AMOS BASIC was written for the Amiga by François Lionet with Constantin Sotiropoulos and published by Europress Software in 1990. History AMOS competed on the Amiga platform with Acid Software's Blitz BASIC. Both BASICs differed from other dialects on different platforms, in that they allowed the easy creation of fairly demanding multimedia software, with full structured code and many high-level functions to load images, animations, sounds and display them in various ways. The original AMOS was a BASIC interpreter which, whilst working fine, suffered the same disadvantages of any language being run interpretively. By all accounts, AMOS was extremely fast among interpreted languages, being speedy enough that an extension called AMOS 3D could produce playable 3D games even on plain 7 MHz 68000 Amigas. Later, an AMOS compiler was developed that further increased speed. AMOS could also run MC68000 machine code, loaded into a program's memory banks. To simplify animation of sprites, AMOS included the AMOS Animation Language (AMAL), a compiled sprite scripting language which runs independently of the main AMOS BASIC program. It was also possible to control screen and "rainbow" effects using AMAL scripts. AMAL scripts in effect created CopperLists, small routines executed by the Amiga's Agnus chip. After the original version of AMOS, Europress released a compiler (AMOS Compiler), and two other versions of the language: Easy AMOS, a simpler version for beginners, and AMOS Professional, a more advanced version with added features, such as a better integrated development environment, ARexx support, a new user interface API and new flow control constructs. Neither of these new versions was significantly more popular than the original AMOS. AMOS was used mostly to make multimedia software, video games (platformers and graphical adventures) and educational software. The language was mildly successful within the Amiga community. Its ease of use made it especially attractive to beginners. Perhaps AMOS BASIC's biggest disadvantage, stemming from its Atari ST lineage, was its incompatibility with the Amiga's operating system functions and interfaces. Instead, AMOS BASIC controlled the computer directly, which caused programs written in it to have a non-standard user interface, and also caused compatibility problems with newer versions of hardware. Today, the language has declined in popularity along with the Amiga computer for which it was written. Despite this, a small community of enthusiasts are still using it. The source code to AMOS was released around 2001 under a BSD style license by Clickteam, a company that includes the original programmer. Software Software written using AMOS BASIC includes: Miggybyte Scorched Tanks Games by Vulcan Software, amongst which was the Valhalla trilogy Amiga version of Ultimate Domain (called Genesia) by Microïds Flight of the Amazon Queen, by Interactive Binary Illusions Extreme Violence, included on an Amiga Power cover disk Jetstrike, a commercial game by Rasputin Software Black Dawn, a 1993 game for the Amiga personal computer References External links Source code for AMOS Professional 68000 ASM from pianetaamiga.it (archived, ZIP) Source code for AMOS and STOS 68000 ASM from clickteam.com (archived, ZIP) The AMOS Factory (an AMOS support/community site) Amigacoding website (contains in-depth info and references for AMOS - Archived version 22 Sep 2015) History of STOS and AMOS: how they came to be published in the UK Amos Professional group on Facebook (one of the members is AMOS' original developer François Lionet) BASIC programming language family Video game development software Amiga development software Software using the BSD license Programming languages created in 1990

https://en.wikipedia.org/wiki/Arcadia%202001

Arcadia 2001

The Arcadia 2001 is a second-generation 8-bit home video game console released by Emerson Radio in May 1982 for a price of US$ 99, several months before the release of ColecoVision. It was discontinued only 18 months later, with a total of 35 games having been released. Emerson licensed the Arcadia 2001 to Bandai, which released it in Japan. Over 30 Arcadia 2001 clones exist. The unrelated Arcadia Corporation, manufacturer of the Atari 2600 Supercharger add-on, was sued by Emerson for trademark infringement. Arcadia Corporation then changed its name to Starpath. Description The Arcadia is much smaller than its contemporary competitors and is powered by a standard 12 volt power supply so it can be used in a boat or a vehicle. It has two headphone jacks on the far left and right sides of the back. The system came with two Intellivision-style controllers with a 12-button keypad and "fire" buttons on the sides. The direction pads have a removable joystick attachment. Most games came with BoPET overlays that can be applied to the controller's keypads. The console itself has five buttons: Power, Start, Reset, Option, and Select. There are at least three different cartridge case styles and artwork, with variations on each. Emerson-family cartridges come in two different lengths (short and long) of black plastic cases. Technical specifications Main Processor: Signetics 2650 CPU (some variants run a Signetics 2650A) RAM: 1 KB ROM: None Video display: 128 × 208 / 128 × 104, 8 Colours Video display controller: Signetics 2637 UVI @ 3.58 MHz (NTSC), 3.55 MHz (PAL) Sound: Single Channel "Beeper" + Single Channel "Noise" Hardware Sprites: 4 independent, single color Controllers: 2 × 2 way Keypads: 2 × 12 button (more buttons on some variants) Console variants and clones Many variants and clones of the Arcadia 2001 have been released by various companies in different countries. These systems are mostly compatible with each other. In 1982, the Bandai Arcadia was released only in Japan. Four exclusive games were released for the system. Bandai Arcadia In 1982, the Bandai Arcadia, a variant of the Emerson Arcadia 2001, was licensed and distributed to Japan by Bandai for a price of 19,800 yen. There were four Japan-exclusive games released by Bandai. Doraemon Dr. Slump Mobile Suit Gundam Super Dimension Fortress Macross Reception After seeing the Arcadia 2001 at the summer 1982 Consumer Electronics Show, Danny Goodman of Creative Computing Video & Arcade Games reported that its graphics were similar to the Atari 2600's, and that "our overall impression of the game play was favorable for a system in this price range, though no cartridge stands out as being an exciting original creation". He called the controller offering both Intellivision-like disc and joystick functionality "A great idea". Games Emerson planned to launch the console with 19 games. Some Arcadia 2001 games are ports of lesser-known arcade games such as Route 16, Jungler, and Jump Bug, which were not available on other home systems. Emerson actually created many popular arcade titles including Pac-Man, Galaxian and Defender for the Arcadia, but never had them manufactured as Atari started to sue its competitor companies for releasing games to which it had exclusive-rights agreements. Early marketing showed popular arcade games, but they were later released as clones. For instance, the Arcadia 2001 game Space Raiders is a clone of Defender, and Breakaway is a clone of Breakout. Released games There are 47 games known to have been released for the Arcadia 2001 and its clones.

https://en.wikipedia.org/wiki/Convex%20uniform%20honeycomb

Convex uniform honeycomb

In geometry, a convex uniform honeycomb is a uniform tessellation which fills three-dimensional Euclidean space with non-overlapping convex uniform polyhedral cells. Twenty-eight such honeycombs are known: the familiar cubic honeycomb and 7 truncations thereof; the alternated cubic honeycomb and 4 truncations thereof; 10 prismatic forms based on the uniform plane tilings (11 if including the cubic honeycomb); 5 modifications of some of the above by elongation and/or gyration. They can be considered the three-dimensional analogue to the uniform tilings of the plane. The Voronoi diagram of any lattice forms a convex uniform honeycomb in which the cells are zonohedra. History 1900: Thorold Gosset enumerated the list of semiregular convex polytopes with regular cells (Platonic solids) in his publication On the Regular and Semi-Regular Figures in Space of n Dimensions, including one regular cubic honeycomb, and two semiregular forms with tetrahedra and octahedra. 1905: Alfredo Andreini enumerated 25 of these tessellations. 1991: Norman Johnson's manuscript Uniform Polytopes identified the list of 28. 1994: Branko Grünbaum, in his paper Uniform tilings of 3-space, also independently enumerated all 28, after discovering errors in Andreini's publication. He found the 1905 paper, which listed 25, had 1 wrong, and 4 being missing. Grünbaum states in this paper that Norman Johnson deserves priority for achieving the same enumeration in 1991. He also mentions that I. Alexeyev of Russia had contacted him regarding a putative enumeration of these forms, but that Grünbaum was unable to verify this at the time. 2006: George Olshevsky, in his manuscript Uniform Panoploid Tetracombs, along with repeating the derived list of 11 convex uniform tilings, and 28 convex uniform honeycombs, expands a further derived list of 143 convex uniform tetracombs (Honeycombs of uniform 4-polytopes in 4-space). Only 14 of the convex uniform polyhedra appear in these patterns: three of the five Platonic solids (the tetrahedron, cube, and octahedron), six of the thirteen Archimedean solids (the ones with reflective tetrahedral or octahedral symmetry), and five of the infinite family of prisms (the 3-, 4-, 6-, 8-, and 12-gonal ones; the 4-gonal prism duplicates the cube). The icosahedron, snub cube, and square antiprism appear in some alternations, but those honeycombs cannot be realised with all edges unit length. Names This set can be called the regular and semiregular honeycombs. It has been called the Archimedean honeycombs by analogy with the convex uniform (non-regular) polyhedra, commonly called Archimedean solids. Recently Conway has suggested naming the set as the Architectonic tessellations and the dual honeycombs as the Catoptric tessellations. The individual honeycombs are listed with names given to them by Norman Johnson. (Some of the terms used below are defined in Uniform 4-polytope#Geometric derivations for 46 nonprismatic Wythoffian uniform 4-polytopes) For cross-referencing, they are given with list indices from Andreini (1-22), Williams(1-2,9-19), Johnson (11-19, 21–25, 31–34, 41–49, 51–52, 61–65), and Grünbaum(1-28). Coxeter uses δ4 for a cubic honeycomb, hδ4 for an alternated cubic honeycomb, qδ4 for a quarter cubic honeycomb, with subscripts for other forms based on the ring patterns of the Coxeter diagram. Compact Euclidean uniform tessellations (by their infinite Coxeter group families) The fundamental infinite Coxeter groups for 3-space are: The , [4,3,4], cubic, (8 unique forms plus one alternation) The , [4,31,1], alternated cubic, (11 forms, 3 new) The cyclic group, [(3,3,3,3)] or [3[4]], (5 forms, one new) There is a correspondence between all three families. Removing one mirror from produces , and removing one mirror from produces . This allows multiple constructions of the same honeycombs. If cells are colored based on unique positions within each Wythoff construction, these different symmetries can be shown. In addition there are 5 special honeycombs which don't have pure reflectional symmetry and are constructed from reflectional forms with elongation and gyration operations. The total unique honeycombs above are 18. The prismatic stacks from infinite Coxeter groups for 3-space are: The ×, [4,4,2,∞] prismatic group, (2 new forms) The ×, [6,3,2,∞] prismatic group, (7 unique forms) The ×, [(3,3,3),2,∞] prismatic group, (No new forms) The ××, [∞,2,∞,2,∞] prismatic group, (These all become a cubic honeycomb) In addition there is one special elongated form of the triangular prismatic honeycomb. The total unique prismatic honeycombs above (excluding the cubic counted previously) are 10. Combining these counts, 18 and 10 gives us the total 28 uniform honeycombs. The C̃3, [4,3,4] group (cubic) The regular cubic honeycomb, represented by Schläfli symbol {4,3,4}, offers seven unique derived uniform honeycombs via truncation operations. (One redundant form, the runcinated cubic honeycomb, is included for completeness though identical to the cubic honeycomb.) The reflectional symmetry is the affine Coxeter group [4,3,4]. There are four index 2 subgroups that generate alternations: [1+,4,3,4], [(4,3,4,2+)], [4,3+,4], and [4,3,4]+, with the first two generated repeated forms, and the last two are nonuniform. B̃3, [4,31,1] group The , [4,3] group offers 11 derived forms via truncation operations, four being unique uniform honeycombs. There are 3 index 2 subgroups that generate alternations: [1+,4,31,1], [4,(31,1)+], and [4,31,1]+. The first generates repeated honeycomb, and the last two are nonuniform but included for completeness. The honeycombs from this group are called alternated cubic because the first form can be seen as a cubic honeycomb with alternate vertices removed, reducing cubic cells to tetrahedra and creating octahedron cells in the gaps. Nodes are indexed left to right as 0,1,0',3 with 0' being below and interchangeable with 0. The alternate cubic names given are based on this ordering. Ã3, [3[4]] group There are 5 forms constructed from the , [3[4]] Coxeter group, of which only the quarter cubic honeycomb is unique. There is one index 2 subgroup [3[4]]+ which generates the snub form, which is not uniform, but included for completeness. Nonwythoffian forms (gyrated and elongated) Three more uniform honeycombs are generated by breaking one or another of the above honeycombs where its faces form a continuous plane, then rotating alternate layers by 60 or 90 degrees (gyration) and/or inserting a layer of prisms (elongation). The elongated and gyroelongated alternated cubic tilings have the same vertex figure, but are not alike. In the elongated form, each prism meets a tetrahedron at one triangular end and an octahedron at the other. In the gyroelongated form, prisms that meet tetrahedra at both ends alternate with prisms that meet octahedra at both ends. The gyroelongated triangular prismatic tiling has the same vertex figure as one of the plain prismatic tilings; the two may be derived from the gyrated and plain triangular prismatic tilings, respectively, by inserting layers of cubes. Prismatic stacks Eleven prismatic tilings are obtained by stacking the eleven uniform plane tilings, shown below, in parallel layers. (One of these honeycombs is the cubic, shown above.) The vertex figure of each is an irregular bipyramid whose faces are isosceles triangles. The C̃2×Ĩ1(∞), [4,4,2,∞], prismatic group There are only 3 unique honeycombs from the square tiling, but all 6 tiling truncations are listed below for completeness, and tiling images are shown by colors corresponding to each form. The G̃2xĨ1(∞), [6,3,2,∞] prismatic group Enumeration of Wythoff forms All nonprismatic Wythoff constructions by Coxeter groups are given below, along with their alternations. Uniform solutions are indexed with Branko Grünbaum's listing. Green backgrounds are shown on repeated honeycombs, with the relations are expressed in the extended symmetry diagrams. Examples All 28 of these tessellations are found in crystal arrangements. The alternated cubic honeycomb is of special importance since its vertices form a cubic close-packing of spheres. The space-filling truss of packed octahedra and tetrahedra was apparently first discovered by Alexander Graham Bell and independently re-discovered by Buckminster Fuller (who called it the octet truss and patented it in the 1940s). . Octet trusses are now among the most common types of truss used in construction. Frieze forms If cells are allowed to be uniform tilings, more uniform honeycombs can be defined: Families: ×: [4,4,2] Cubic slab honeycombs (3 forms) ×: [6,3,2] Tri-hexagonal slab honeycombs (8 forms) ×: [(3,3,3),2] Triangular slab honeycombs (No new forms) ××: [∞,2,2] = Cubic column honeycombs (1 form) ×: [p,2,∞] Polygonal column honeycombs (analogous to duoprisms: these look like a single infinite tower of p-gonal prisms, with the remaining space filled with apeirogonal prisms) ××: [∞,2,∞,2] = [4,4,2] - = (Same as cubic slab honeycomb family) The first two forms shown above are semiregular (uniform with only regular facets), and were listed by Thorold Gosset in 1900 respectively as the 3-ic semi-check and tetroctahedric semi-check. Scaliform honeycomb A scaliform honeycomb is vertex-transitive, like a uniform honeycomb, with regular polygon faces while cells and higher elements are only required to be orbiforms, equilateral, with their vertices lying on hyperspheres. For 3D honeycombs, this allows a subset of Johnson solids along with the uniform polyhedra. Some scaliforms can be generated by an alternation process, leaving, for example, pyramid and cupola gaps. Hyperbolic forms There are 9 Coxeter group families of compact uniform honeycombs in hyperbolic 3-space, generated as Wythoff constructions, and represented by ring permutations of the Coxeter-Dynkin diagrams for each family. From these 9 families, there are a total of 76 unique honeycombs generated: [3,5,3] : - 9 forms [5,3,4] : - 15 forms [5,3,5] : - 9 forms [5,31,1] : - 11 forms (7 overlap with [5,3,4] family, 4 are unique) [(4,3,3,3)] : - 9 forms [(4,3,4,3)] : - 6 forms [(5,3,3,3)] : - 9 forms [(5,3,4,3)] : - 9 forms [(5,3,5,3)] : - 6 forms Several non-Wythoffian forms outside the list of 76 are known; it is not known how many there are. Paracompact hyperbolic forms There are also 23 paracompact Coxeter groups of rank 4. These families can produce uniform honeycombs with unbounded facets or vertex figure, including ideal vertices at infinity: References John H.

Alcoholism

Alcoholism is the continued drinking of alcohol despite negative results. Problematic use of alcohol has been mentioned in the earliest historical records, such as in ancient Egypt and in the Bible, and remains widespread; the World Health Organization (WHO) estimated there were 283 million people with alcohol use disorders worldwide . The term alcoholism was first coined in 1852, but alcoholism and alcoholic are stigmatizing and discourage seeking treatment, so clinical diagnostic terms such as alcohol use disorder or alcohol dependence are used instead. Alcohol is addictive, and heavy long-term alcohol use results in many negative health and social consequences. It can damage all the organ systems, but especially affects the brain, heart, liver, pancreas and immune system. Heavy alcohol usage can result in trouble sleeping, and severe cognitive issues like dementia, brain damage, or Wernicke–Korsakoff syndrome. Physical effects include irregular heartbeat, an impaired immune response, liver cirrhosis, increased cancer risk, and severe withdrawal symptoms if stopped suddenly. These health effects can reduce life expectancy by 10 years. Drinking during pregnancy may harm the child's health, and drunk driving increases the risk of traffic accidents. Alcoholism is also associated with increases in violent and non-violent crime. While alcoholism directly resulted in 139,000 deaths in 2013, 3.3 million deaths may be attributable to alcohol. The development of alcoholism is attributed to both environment and genetics equally. The use of alcohol to self-medicate stress or anxiety can turn into alcoholism. Someone with a parent or sibling with an alcohol use disorder is three to four times more likely to develop an alcohol use disorder themselves, but only a minority of them do. Environmental factors include social, cultural and behavioral influences. High stress levels and anxiety, as well as alcohol's inexpensive cost and easy accessibility, increase the risk. People may continue to drink partly to prevent or improve symptoms of withdrawal. After a person stops drinking alcohol, they may experience a low level of withdrawal lasting for months. Medically, alcoholism is considered both a physical and mental illness. Questionnaires are usually used to detect possible alcoholism. Further information is then collected to confirm the diagnosis. Treatment of alcoholism may take several forms. Due to medical problems that can occur during withdrawal, alcohol cessation should be controlled carefully. One common method involves the use of benzodiazepine medications, such as diazepam. These can be taken while admitted to a health care institution or individually. The medications acamprosate or disulfiram may also be used to help prevent further drinking. Mental illness or other addictions may complicate treatment. Various individual or group therapy or support groups are used to attempt to keep a person from returning to alcoholism. Among them is the abstinence based mutual aid fellowship Alcoholics Anonymous (AA). A 2020 scientific review found that clinical interventions encouraging increased participation in AA (AA/twelve step facilitation (AA/TSF))—resulted in higher abstinence rates over other clinical interventions, and most studies in the review found that AA/TSF led to lower health costs. Many terms, some slurs and some informal, have been used to refer to people affected by alcoholism such as tippler, drunkard, dipsomaniac and souse. Signs and symptoms The risk of alcohol dependence begins at low levels of drinking and increases directly with both the volume of alcohol consumed and a pattern of drinking larger amounts on an occasion, to the point of intoxication, which is sometimes called binge drinking. Long-term misuse Alcoholism is characterised by an increased tolerance to alcohol – which means that an individual can consume more alcohol – and physical dependence on alcohol, which makes it hard for an individual to control their consumption. The physical dependency caused by alcohol can lead to an affected individual having a very strong urge to drink alcohol. These characteristics play a role in decreasing the ability to stop drinking of an individual with an alcohol use disorder. Alcoholism can have adverse effects on mental health, contributing to psychiatric disorders and increasing the risk of suicide. A depressed mood is a common symptom of heavy alcohol drinkers. Warning signs Warning signs of alcoholism include the consumption of increasing amounts of alcohol and frequent intoxication, preoccupation with drinking to the exclusion of other activities, promises to quit drinking and failure to keep those promises, the inability to remember what was said or done while drinking (colloquially known as "blackouts"), personality changes associated with drinking, denial or the making of excuses for drinking, the refusal to admit excessive drinking, dysfunction or other problems at work or school, the loss of interest in personal appearance or hygiene, marital and economic problems, and the complaint of poor health, with loss of appetite, respiratory infections, or increased anxiety. Physical Short-term effects Drinking enough to cause a blood alcohol concentration (BAC) of 0.03–0.12% typically causes an overall improvement in mood and possible euphoria (intense feelings of well-being and happiness), increased self-confidence and sociability, decreased anxiety, a flushed, red appearance in the face and impaired judgment and fine muscle coordination. A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision. A BAC of 0.18% to 0.30% causes profound confusion, impaired speech (e.g. slurred speech), staggering, dizziness and vomiting. A BAC from 0.25% to 0.40% causes stupor, unconsciousness, anterograde amnesia, vomiting (death may occur due to inhalation of vomit while unconscious) and respiratory depression (potentially life-threatening). A BAC from 0.35% to 0.80% causes a coma (unconsciousness), life-threatening respiratory depression and possibly fatal alcohol poisoning. With all alcoholic beverages, drinking while driving, operating an aircraft or heavy machinery increases the risk of an accident; many countries have penalties for drunk driving. Long-term effects Having more than one drink a day for women or two drinks for men increases the risk of heart disease, high blood pressure, atrial fibrillation, and stroke. Risk is greater with binge drinking, which may also result in violence or accidents. About 3.3 million deaths (5.9% of all deaths) are believed to be due to alcohol each year. Alcoholism reduces a person's life expectancy by around ten years and alcohol use is the third leading cause of early death in the United States. Long-term alcohol misuse can cause a number of physical symptoms, including cirrhosis of the liver, pancreatitis, epilepsy, polyneuropathy, alcoholic dementia, heart disease, nutritional deficiencies, peptic ulcers and sexual dysfunction, and can eventually be fatal. Other physical effects include an increased risk of developing cardiovascular disease, malabsorption, alcoholic liver disease, and several cancers. Damage to the central nervous system and peripheral nervous system can occur from sustained alcohol consumption. A wide range of immunologic defects can result and there may be a generalized skeletal fragility, in addition to a recognized tendency to accidental injury, resulting in a propensity for bone fractures. Women develop long-term complications of alcohol dependence more rapidly than do men, women also have a higher mortality rate from alcoholism than men. Examples of long-term complications include brain, heart, and liver damage and an increased risk of breast cancer. Additionally, heavy drinking over time has been found to have a negative effect on reproductive functioning in women. This results in reproductive dysfunction such as anovulation, decreased ovarian mass, problems or irregularity of the menstrual cycle, and early menopause. Alcoholic ketoacidosis can occur in individuals who chronically misuse alcohol and have a recent history of binge drinking. The amount of alcohol that can be biologically processed and its effects differ between sexes. Equal dosages of alcohol consumed by men and women generally result in women having higher blood alcohol concentrations (BACs), since women generally have a lower weight and higher percentage of body fat and therefore a lower volume of distribution for alcohol than men. Psychiatric Long-term misuse of alcohol can cause a wide range of mental health problems. Severe cognitive problems are common; approximately 10% of all dementia cases are related to alcohol consumption, making it the second leading cause of dementia. Excessive alcohol use causes damage to brain function, and psychological health can be increasingly affected over time. Social skills are significantly impaired in people with alcoholism due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. The social skills that are impaired by alcohol use disorder include impairments in perceiving facial emotions, prosody, perception problems, and theory of mind deficits; the ability to understand humor is also impaired in people who misuse alcohol. Psychiatric disorders are common in people with alcohol use disorders, with as many as 25% also having severe psychiatric disturbances. The most prevalent psychiatric symptoms are anxiety and depression disorders. Psychiatric symptoms usually initially worsen during alcohol withdrawal, but typically improve or disappear with continued abstinence. Psychosis, confusion, and organic brain syndrome may be caused by alcohol misuse, which can lead to a misdiagnosis such as schizophrenia. Panic disorder can develop or worsen as a direct result of long-term alcohol misuse. The co-occurrence of major depressive disorder and alcoholism is well documented. Among those with comorbid occurrences, a distinction is commonly made between depressive episodes that remit with alcohol abstinence ("substance-induced"), and depressive episodes that are primary and do not remit with abstinence ("independent" episodes). Additional use of other drugs may increase the risk of depression. Psychiatric disorders differ depending on gender. Women who have alcohol-use disorders often have a co-occurring psychiatric diagnosis such as major depression, anxiety, panic disorder, bulimia, post-traumatic stress disorder (PTSD), or borderline personality disorder. Men with alcohol-use disorders more often have a co-occurring diagnosis of narcissistic or antisocial personality disorder, bipolar disorder, schizophrenia, impulse disorders or attention deficit/hyperactivity disorder (ADHD). Women with alcohol use disorder are more likely to experience physical or sexual assault, abuse, and domestic violence than women in the general population, which can lead to higher instances of psychiatric disorders and greater dependence on alcohol. Social effects Serious social problems arise from alcohol use disorder; these dilemmas are caused by the pathological changes in the brain and the intoxicating effects of alcohol. Alcohol misuse is associated with an increased risk of committing criminal offences, including child abuse, domestic violence, rape, burglary and assault. Alcoholism is associated with loss of employment, which can lead to financial problems. Drinking at inappropriate times and behavior caused by reduced judgment can lead to legal consequences, such as criminal charges for drunk driving or public disorder, or civil penalties for tortious behavior. An alcoholic's behavior and mental impairment while drunk can profoundly affect those surrounding him and lead to isolation from family and friends. This isolation can lead to marital conflict and divorce, or contribute to domestic violence. Alcoholism can also lead to child neglect, with subsequent lasting damage to the emotional development of children of people with alcohol use disorders. For this reason, children of people with alcohol use disorders can develop a number of emotional problems. For example, they can become afraid of their parents, because of their unstable mood behaviors. They may develop shame over their inadequacy to liberate their parents from alcoholism and, as a result of this, may develop self-image problems, which can lead to depression. Alcohol withdrawal As with similar substances with a sedative-hypnotic mechanism, such as barbiturates and benzodiazepines, withdrawal from alcohol dependence can be fatal if it is not properly managed. Alcohol's primary effect is the increase in stimulation of the GABAA receptor, promoting central nervous system depression. With repeated heavy consumption of alcohol, these receptors are desensitized and reduced in number, resulting in tolerance and physical dependence. When alcohol consumption is stopped too abruptly, the person's nervous system experiences uncontrolled synapse firing. This can result in symptoms that include anxiety, life-threatening seizures, delirium tremens, hallucinations, shakes and possible heart failure. Other neurotransmitter systems are also involved, especially dopamine, NMDA and glutamate. Severe acute withdrawal symptoms such as delirium tremens and seizures rarely occur after 1-week post cessation of alcohol. The acute withdrawal phase can be defined as lasting between one and three weeks. In the period of 3–6 weeks following cessation, anxiety, depression, fatigue, and sleep disturbance are common. Similar post-acute withdrawal symptoms have also been observed in animal models of alcohol dependence and withdrawal. A kindling effect also occurs in people with alcohol use disorders whereby each subsequent withdrawal syndrome is more severe than the previous withdrawal episode; this is due to neuroadaptations which occur as a result of periods of abstinence followed by re-exposure to alcohol. Individuals who have had multiple withdrawal episodes are more likely to develop seizures and experience more severe anxiety during withdrawal from alcohol than alcohol-dependent individuals without a history of past alcohol withdrawal episodes. The kindling effect leads to persistent functional changes in brain neural circuits as well as to gene expression. Kindling also results in the intensification of psychological symptoms of alcohol withdrawal. There are decision tools and questionnaires that help guide physicians in evaluating alcohol withdrawal. For example, the CIWA-Ar objectifies alcohol withdrawal symptoms in order to guide therapy decisions which allows for an efficient interview while at the same time retaining clinical usefulness, validity, and reliability, ensuring proper care for withdrawal patients, who can be in danger of death. Causes A complex combination of genetic and environmental factors influences the risk of the development of alcoholism. Genes that influence the metabolism of alcohol also influence the risk of alcoholism, as can a family history of alcoholism. There is compelling evidence that alcohol use at an early age may influence the expression of genes which increase the risk of alcohol dependence. These genetic and epigenetic results are regarded as consistent with large longitudinal population studies finding that the younger the age of drinking onset, the greater the prevalence of lifetime alcohol dependence. Severe childhood trauma is also associated with a general increase in the risk of drug dependency. Lack of peer and family support is associated with an increased risk of alcoholism developing. Genetics and adolescence are associated with an increased sensitivity to the neurotoxic effects of chronic alcohol misuse. Cortical degeneration due to the neurotoxic effects increases impulsive behaviour, which may contribute to the development, persistence and severity of alcohol use disorders. There is evidence that with abstinence, there is a reversal of at least some of the alcohol induced central nervous system damage. The use of cannabis was associated with later problems with alcohol use. Alcohol use was associated with an increased probability of later use of tobacco and illegal drugs such as cannabis. Availability Alcohol is the most available, widely consumed, and widely misused recreational drug. Beer alone is the world's most widely consumed alcoholic beverage; it is the third-most popular drink overall, after water and tea. It is thought by some to be the oldest fermented beverage. Gender difference Based on combined data in the US from SAMHSA's 2004–2005 National Surveys on Drug Use & Health, the rate of past-year alcohol dependence or misuse among persons aged 12 or older varied by level of alcohol use: 44.7% of past month heavy drinkers, 18.5% binge drinkers, 3.8% past month non-binge drinkers, and 1.3% of those who did not drink alcohol in the past month met the criteria for alcohol dependence or misuse in the past year. Males had higher rates than females for all measures of drinking in the past month: any alcohol use (57.5% vs. 45%), binge drinking (30.8% vs. 15.1%), and heavy alcohol use (10.5% vs. 3.3%), and males were twice as likely as females to have met the criteria for alcohol dependence or misuse in the past year (10.5% vs. 5.1%). Genetic variation There are genetic variations that affect the risk for alcoholism. Some of these variations are more common in individuals with ancestry from certain areas; for example, Africa, East Asia, the Middle East and Europe. The variants with strongest effect are in genes that encode the main enzymes of alcohol metabolism, ADH1B and ALDH2. These genetic factors influence the rate at which alcohol and its initial metabolic product, acetaldehyde, are metabolized. They are found at different frequencies in people from different parts of the world. The alcohol dehydrogenase allele ADH1B*2 causes a more rapid metabolism of alcohol to acetaldehyde, and reduces risk for alcoholism; it is most common in individuals from East Asia and the Middle East. The alcohol dehydrogenase allele ADH1B*3 also causes a more rapid metabolism of alcohol. The allele ADH1B*3 is only found in some individuals of African descent and certain Native American tribes. African Americans and Native Americans with this allele have a reduced risk of developing alcoholism. Native Americans, however, have a significantly higher rate of alcoholism than average; risk factors such as cultural environmental effects (e.g. trauma) have been proposed to explain the higher rates. The aldehyde dehydrogenase allele ALDH2*2 greatly reduces the rate at which acetaldehyde, the initial product of alcohol metabolism, is removed by conversion to acetate; it greatly reduces the risk for alcoholism. A genome-wide association study (GWAS) of more than 100,000 human individuals identified variants of the gene KLB, which encodes the transmembrane protein β-Klotho, as highly associated with alcohol consumption. The protein β-Klotho is an essential element in cell surface receptors for hormones involved in modulation of appetites for simple sugars and alcohol. Several large GWAS have found differences in the genetics of alcohol consumption and alcohol dependence, although the two are to some degree related. DNA damage Alcohol-induced DNA damage, when not properly repaired, may have a key role in the neurotoxicity induced by alcohol. Metabolic conversion of ethanol to acetaldehyde can occur in the brain and the neurotoxic effects of ethanol appear to be associated with acetaldehyde induced DNA damages including DNA adducts and crosslinks. In addition to acetaldehyde, alcohol metabolism produces potentially genotoxic reactive oxygen species, which have been demonstrated to cause oxidative DNA damage. Diagnosis Definition Because there is disagreement on the definition of the word alcoholism, it is not a recognized diagnosis, and the use of the term alcoholism is discouraged due to its heavily stigmatized connotations. It is classified as alcohol use disorder in the DSM-5 or alcohol dependence in the ICD-11. In 1979, the World Health Organization discouraged the use of alcoholism due to its inexact meaning, preferring alcohol dependence syndrome. Misuse, problem use, abuse, and heavy use of alcohol refer to improper use of alcohol, which may cause physical, social, or moral harm to the drinker. The Dietary Guidelines for Americans, issued by the United States Department of Agriculture (USDA) in 2005, defines "moderate use" as no more than two alcoholic beverages a day for men and no more than one alcoholic beverage a day for women. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines binge drinking as the amount of alcohol leading to a blood alcohol content (BAC) of 0.08, which, for most adults, would be reached by consuming five drinks for men or four for women over a two-hour period. According to the NIAAA, men may be at risk for alcohol-related problems if their alcohol consumption exceeds 14 standard drinks per week or 4 drinks per day, and women may be at risk if they have more than 7 standard drinks per week or 3 drinks per day. It defines a standard drink as one 12-ounce bottle of beer, one 5-ounce glass of wine, or 1.5 ounces of distilled spirits. Despite this risk, a 2014 report in the National Survey on Drug Use and Health found that only 10% of either "heavy drinkers" or "binge drinkers" defined according to the above criteria also met the criteria for alcohol dependence, while only 1.3% of non-binge drinkers met the criteria. An inference drawn from this study is that evidence-based policy strategies and clinical preventive services may effectively reduce binge drinking without requiring addiction treatment in most cases. Alcoholism The term alcoholism is commonly used amongst laypeople, but the word is poorly defined. Despite the imprecision inherent in the term, there have been attempts to define how the word alcoholism should be interpreted when encountered. In 1992, it was defined by the National Council on Alcoholism and Drug Dependence (NCADD) and ASAM as "a primary, chronic disease characterized by impaired control over drinking, preoccupation with the drug alcohol, use of alcohol despite adverse consequences, and distortions in thinking." MeSH has had an entry for alcoholism since 1999, and references the 1992 definition. The WHO calls alcoholism "a term of long-standing use and variable meaning", and use of the term was disfavored by a 1979 WHO expert committee. In professional and research contexts, the term alcoholism is not currently favored, but rather alcohol abuse, alcohol dependence, or alcohol use disorder are used. Talbot (1989) observes that alcoholism in the classical disease model follows a progressive course: if people continue to drink, their condition will worsen. This will lead to harmful consequences in their lives, physically, mentally, emotionally, and socially. Johnson (1980) proposed that the emotional progression of the addicted people's response to alcohol has four phases. The first two are considered "normal" drinking and the last two are viewed as "typical" alcoholic drinking. Johnson's four phases consist of: Learning the mood swing. People are introduced to alcohol (in some cultures this can happen at a relatively young age), and they enjoy the happy feeling it produces. At this stage, there is no emotional cost. Seeking the mood swing. People will drink to regain that happy feeling in phase 1; the drinking will increase as more alcohol is required to achieve the same effect. Again at this stage, there are no significant consequences. At the third stage there are physical and social consequences such as hangovers, family problems, and work problems. People will continue to drink excessively, disregarding the problems. The fourth stage can be detrimental with a risk for premature death. People in this phase now drink to feel normal, they block out the feelings of overwhelming guilt, remorse, anxiety, and shame they experience when sober. DSM and ICD In the United States, the Diagnostic and Statistical Manual of Mental Disorders (DSM) is the most common diagnostic guide for substance use disorders, whereas most countries use the International Classification of Diseases (ICD) for diagnostic (and other) purposes. The two manuals use similar but not identical nomenclature to classify alcohol problems. Social barriers Attitudes and social stereotypes can create barriers to the detection and treatment of alcohol use disorder. This is more of a barrier for women than men. Fear of stigmatization may lead women to deny that they have a medical condition, to hide their drinking, and to drink alone. This pattern, in turn, leads family, physicians, and others to be less likely to suspect that a woman they know has alcohol use disorder. In contrast, reduced fear of stigma may lead men to admit that they are having a medical condition, to display their drinking publicly, and to drink in groups. This pattern, in turn, leads family, physicians, and others to be more likely to suspect that a man they know is someone with an alcohol use disorder. Screening Screening is recommended among those over the age of 18. Several tools may be used to detect a loss of control of alcohol use. These tools are mostly self-reports in questionnaire form. Another common theme is a score or tally that sums up the general severity of alcohol use. The CAGE questionnaire, named for its four questions, is one such example that may be used to screen patients quickly in a doctor's office. The CAGE questionnaire has demonstrated a high effectiveness in detecting alcohol-related problems; however, it has limitations in people with less severe alcohol-related problems, white women and college students. Other tests are sometimes used for the detection of alcohol dependence, such as the Alcohol Dependence Data Questionnaire, which is a more sensitive diagnostic test than the CAGE questionnaire. It helps distinguish a diagnosis of alcohol dependence from one of heavy alcohol use. The Michigan Alcohol Screening Test (MAST) is a screening tool for alcoholism widely used by courts to determine the appropriate sentencing for people convicted of alcohol-related offenses, driving under the influence being the most common. The Alcohol Use Disorders Identification Test (AUDIT), a screening questionnaire developed by the World Health Organization, is unique in that it has been validated in six countries and is used internationally. Like the CAGE questionnaire, it uses a simple set of questions – a high score earning a deeper investigation. The Paddington Alcohol Test (PAT) was designed to screen for alcohol-related problems amongst those attending Accident and Emergency departments. It concords well with the AUDIT questionnaire but is administered in a fifth of the time. Urine and blood tests There are reliable tests for the actual use of alcohol, one common test being that of blood alcohol content (BAC). These tests do not differentiate people with alcohol use disorders from people without; however, long-term heavy drinking does have a few recognizable effects on the body, including: Macrocytosis (enlarged MCV) Elevated GGT Moderate elevation of AST and ALT and an AST: ALT ratio of 2:1 High carbohydrate deficient transferrin (CDT) With regard to alcoholism, BAC is useful to judge alcohol tolerance, which in turn is a sign of alcoholism. Electrolyte and acid-base abnormalities including hypokalemia, hypomagnesemia, hyponatremia, hyperuricemia, metabolic acidosis, and respiratory alkalosis are common in people with alcohol use disorders. However, none of these blood tests for biological markers is as sensitive as screening questionnaires. Prevention The World Health Organization, the European Union and other regional bodies, national governments and parliaments have formed alcohol policies in order to reduce the harm of alcoholism. Increasing the age at which alcohol can be purchased, and banning or restricting alcohol beverage advertising are common methods to reduce alcohol use among adolescents and young adults in particular. Another common method of alcoholism prevention is taxation of alcohol products – increasing price of alcohol by 10% is linked with reduction of consumption of up to 10%. Credible, evidence-based educational campaigns in the mass media about the consequences of alcohol misuse have been recommended. Guidelines for parents to prevent alcohol misuse amongst adolescents, and for helping young people with mental health problems have also been suggested. Because alcohol is often used for self-medication of conditions like anxiety temporarily, prevention of alcoholism may be attempted by reducing the severity or prevalence of stress and anxiety in individuals. Management Treatments are varied because there are multiple perspectives of alcoholism. Those who approach alcoholism as a medical condition or disease recommend differing treatments from, for instance, those who approach the condition as one of social choice. Most treatments focus on helping people discontinue their alcohol intake, followed up with life training and/or social support to help them resist a return to alcohol use. Since alcoholism involves multiple factors which encourage a person to continue drinking, they must all be addressed to successfully prevent a relapse. An example of this kind of treatment is detoxification followed by a combination of supportive therapy, attendance at self-help groups, and ongoing development of coping mechanisms. Much of the treatment community for alcoholism supports an abstinence-based zero tolerance approach popularized by the 12 step program of Alcoholics Anonymous; however, some prefer a harm-reduction approach. Cessation of alcohol intake Medical treatment for alcohol detoxification usually involves administration of a benzodiazepine, in order to ameliorate alcohol withdrawal syndrome's adverse impact. The addition of phenobarbital improves outcomes if benzodiazepine administration lacks the usual efficacy, and phenobarbital alone might be an effective treatment. Propofol also might enhance treatment for individuals showing limited therapeutic response to a benzodiazepine. Individuals who are only at risk of mild to moderate withdrawal symptoms can be treated as outpatients. Individuals at risk of a severe withdrawal syndrome as well as those who have significant or acute comorbid conditions can be treated as inpatients. Direct treatment can be followed by a treatment program for alcohol dependence or alcohol use disorder to attempt to reduce the risk of relapse. Experiences following alcohol withdrawal, such as depressed mood and anxiety, can take weeks or months to abate while other symptoms persist longer due to persisting neuroadaptations. Psychological Various forms of group therapy or psychotherapy are sometimes used to encourage and support abstinence from alcohol, or to reduce alcohol consumption to levels that are not associated with adverse outcomes. Mutual-aid group-counseling is an approach used to facilitate relapse prevention. Alcoholics Anonymous was one of the earliest organizations formed to provide mutual peer support and non-professional counseling, however the effectiveness of Alcoholics Anonymous is disputed. A 2020 Cochrane review concluded that Twelve-Step Facilitation (TSF) probably achieves outcomes such as fewer drinks per drinking day, however evidence for such a conclusion comes from low to moderate certainty evidence "so should be regarded with caution". Others include LifeRing Secular Recovery, SMART Recovery, Women for Sobriety, and Secular Organizations for Sobriety. Manualized Twelve Step Facilitation (TSF) interventions (i.e. therapy which encourages active, long-term Alcoholics Anonymous participation) for Alcohol Use Disorder lead to higher abstinence rates, compared to other clinical interventions and to wait-list control groups. Moderate drinking Moderate drinking amongst people with alcohol dependence - often termed 'controlled drinking' - has been subject to significant controversy. Indeed much of the skepticism towards the viability of moderate drinking goals stems from historical ideas about 'alcoholism', now replaced with 'alcohol use disorder' or alcohol dependence in most scientific contexts. A 2021 meta-analysis and systematic review of controlled drinking covering 22 studies concluded controlled drinking was a 'non-inferior' outcome to abstinence for many drinkers. Rationing and moderation programs such as Moderation Management and DrinkWise do not mandate complete abstinence. While most people with alcohol use disorders are unable to limit their drinking in this way, some return to moderate drinking. A 2002 US study by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) showed that 17.7% of individuals diagnosed as alcohol dependent more than one year prior returned to low-risk drinking. This group, however, showed fewer initial symptoms of dependency. A follow-up study, using the same subjects that were judged to be in remission in 2001–2002, examined the rates of return to problem drinking in 2004–2005. The study found abstinence from alcohol was the most stable form of remission for recovering alcoholics. There was also a 1973 study showing chronic alcoholics drinking moderately again, but a 1982 follow-up showed that 95% of subjects were not able to maintain drinking in moderation over the long term. Another study was a long-term (60 year) follow-up of two groups of alcoholic men which concluded that "return to controlled drinking rarely persisted for much more than a decade without relapse or evolution into abstinence." Internet based measures appear to be useful at least in the short term. Medications In the United States there are four approved medications for alcoholism: acamprosate, two methods of using naltrexone and disulfiram. Acamprosate may stabilise the brain chemistry that is altered due to alcohol dependence via antagonising the actions of glutamate, a neurotransmitter which is hyperactive in the post-withdrawal phase. By reducing excessive NMDA activity which occurs at the onset of alcohol withdrawal, acamprosate can reduce or prevent alcohol withdrawal related neurotoxicity. Acamprosate reduces the risk of relapse amongst alcohol-dependent persons. Naltrexone is a competitive antagonist for opioid receptors, effectively blocking the effects of endorphins and opioids. Naltrexone is used to decrease cravings for alcohol and encourage abstinence. Alcohol causes the body to release endorphins, which in turn release dopamine and activate the reward pathways; hence in the body Naltrexone reduces the pleasurable effects from consuming alcohol. Evidence supports a reduced risk of relapse among alcohol-dependent persons and a decrease in excessive drinking. Nalmefene also appears effective and works in a similar manner. Disulfiram prevents the elimination of acetaldehyde, a chemical the body produces when breaking down ethanol. Acetaldehyde itself is the cause of many hangover symptoms from alcohol use. The overall effect is discomfort when alcohol is ingested: an extremely rapid and long-lasting, uncomfortable hangover. Several other drugs are also used and many are under investigation. Benzodiazepines, while useful in the management of acute alcohol withdrawal, if used long-term can cause a worse outcome in alcoholism. Alcoholics on chronic benzodiazepines have a lower rate of achieving abstinence from alcohol than those not taking benzodiazepines. This class of drugs is commonly prescribed to alcoholics for insomnia or anxiety management. Initiating prescriptions of benzodiazepines or sedative-hypnotics in individuals in recovery has a high rate of relapse with one author reporting more than a quarter of people relapsed after being prescribed sedative-hypnotics. Those who are long-term users of benzodiazepines should not be withdrawn rapidly, as severe anxiety and panic may develop, which are known risk factors for alcohol use disorder relapse. Taper regimes of 6–12 months have been found to be the most successful, with reduced intensity of withdrawal. Calcium carbimide works in the same way as disulfiram; it has an advantage in that the occasional adverse effects of disulfiram, hepatotoxicity and drowsiness, do not occur with calcium carbimide. Ondansetron and topiramate are supported by tentative evidence in people with certain genetic patterns. Evidence for ondansetron is stronger in people who have recently started to abuse alcohol. Topiramate is a derivative of the naturally occurring sugar monosaccharide D-fructose. Review articles characterize topiramate as showing "encouraging", "promising", "efficacious", and "insufficient" results in the treatment of alcohol use disorders. Evidence does not support the use of selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), antipsychotics, or gabapentin. Research Topiramate, a derivative of the naturally occurring sugar monosaccharide D-fructose, has been found effective in helping alcoholics quit or cut back on the amount they drink. Evidence suggests that topiramate antagonizes excitatory glutamate receptors, inhibits dopamine release, and enhances inhibitory gamma-aminobutyric acid function. A 2008 review of the effectiveness of topiramate concluded that the results of published trials are promising, however as of 2008, data was insufficient to support using topiramate in conjunction with brief weekly compliance counseling as a first-line agent for alcohol dependence. A 2010 review found that topiramate may be superior to existing alcohol pharmacotherapeutic options. Topiramate effectively reduces craving and alcohol withdrawal severity as well as improving quality-of-life-ratings. Baclofen, a GABAB receptor agonist, is under study for the treatment of alcoholism. According to a 2017 Cochrane Systematic Review, there is insufficient evidence to determine the effectiveness or safety for the use of baclofen for withdrawal symptoms in alcoholism. Psilocybin-assisted psychotherapy is under study for the treatment of patients with alcohol use disorder. Dual addictions and dependencies Alcoholics may also require treatment for other psychotropic drug addictions and drug dependencies. The most common dual dependence syndrome with alcohol dependence is benzodiazepine dependence, with studies showing 10–20% of alcohol-dependent individuals had problems of dependence and/or misuse problems of benzodiazepine drugs such as diazepam or clonazepam. These drugs are, like alcohol, depressants. Benzodiazepines may be used legally, if they are prescribed by doctors for anxiety problems or other mood disorders, or they may be purchased as illegal drugs. Benzodiazepine use increases cravings for alcohol and the volume of alcohol consumed by problem drinkers. Benzodiazepine dependency requires careful reduction in dosage to avoid benzodiazepine withdrawal syndrome and other health consequences. Dependence on other sedative-hypnotics such as zolpidem and zopiclone as well as opiates and illegal drugs is common in alcoholics. Alcohol itself is a sedative-hypnotic and is cross-tolerant with other sedative-hypnotics such as barbiturates, benzodiazepines and nonbenzodiazepines. Dependence upon and withdrawal from sedative-hypnotics can be medically severe and, as with alcohol withdrawal, there is a risk of psychosis or seizures if not properly managed. Epidemiology The World Health Organization estimates that there are about 380 million people with alcoholism worldwide (5.1% of the population over 15 years of age), with it being most common among males and young adults. Geographically, it is least common in Africa (1.1% of the population) and has the highest rates in Eastern Europe (11%). in the United States, about 17 million (7%) of adults and 0.7 million (2.8%) of those age 12 to 17 years of age are affected. About 12% of American adults have had an alcohol dependence problem at some time in their life. In the United States and Western Europe, 10–20% of men and 5–10% of women at some point in their lives will meet criteria for alcoholism. In England, the number of "dependent drinkers" was calculated as over 600,000 in 2019. Estonia had the highest death rate from alcohol in Europe in 2015 at 8.8 per 100,000 population. In the United States, 30% of people admitted to hospital have a problem related to alcohol. Within the medical and scientific communities, there is a broad consensus regarding alcoholism as a disease state. For example, the American Medical Association considers alcohol a drug and states that "drug addiction is a chronic, relapsing brain disease characterized by compulsive drug seeking and use despite often devastating consequences. It results from a complex interplay of biological vulnerability, environmental exposure, and developmental factors (e.g., stage of brain maturity)." Alcoholism has a higher prevalence among men, though, in recent decades, the proportion of female alcoholics has increased. Current evidence indicates that in both men and women, alcoholism is 50–60% genetically determined, leaving 40–50% for environmental influences. Most alcoholics develop alcoholism during adolescence or young adulthood. Prognosis Alcoholism often reduces a person's life expectancy by around ten years. The most common cause of death in alcoholics is from cardiovascular complications. There is a high rate of suicide in chronic alcoholics, which increases the longer a person drinks. Approximately 3–15% of alcoholics die by suicide, and research has found that over 50% of all suicides are associated with alcohol or drug dependence. This is believed to be due to alcohol causing physiological distortion of brain chemistry, as well as social isolation. Suicide is also very common in adolescent alcohol abusers, with 25% of suicides in adolescents being related to alcohol abuse. Among those with alcohol dependence after one year, some met the criteria for low-risk drinking, even though only 26% of the group received any treatment, with the breakdown as follows: 25% were found to be still dependent, 27% were in partial remission (some symptoms persist), 12% asymptomatic drinkers (consumption increases chances of relapse) and 36% were fully recovered – made up of 18% low-risk drinkers plus 18% abstainers. In contrast, however, the results of a long-term (60-year) follow-up of two groups of alcoholic men indicated that "return to controlled drinking rarely persisted for much more than a decade without relapse or evolution into abstinence....return-to-controlled drinking, as reported in short-term studies, is often a mirage." History Historically the name dipsomania was coined by German physician C. W. Hufeland in 1819 before it was superseded by alcoholism. That term now has a more specific meaning. The term alcoholism was first used by Swedish physician Magnus Huss in an 1852 publication to describe the systemic adverse effects of alcohol. Alcohol has a long history of use and misuse throughout recorded history. Biblical, Egyptian and Babylonian sources record the history of abuse and dependence on alcohol. In some ancient cultures alcohol was worshiped and in others, its misuse was condemned. Excessive alcohol misuse and drunkenness were recognized as causing social problems even thousands of years ago. However, the defining of habitual drunkenness as it was then known as and its adverse consequences were not well established medically until the 18th century. In 1647 a Greek monk named Agapios was the first to document that chronic alcohol misuse was associated with toxicity to the nervous system and body which resulted in a range of medical disorders such as seizures, paralysis, and internal bleeding. In the 1910s and 1920s, the effects of alcohol misuse and chronic drunkenness boosted membership of the temperance movement and led to the prohibition of alcohol in many Western countries, nationwide bans on the production, importation, transportation, and sale of alcoholic beverages that generally remained in place until the late 1920s or early 1930s; these policies resulted in the decline of death rates from cirrhosis and alcoholism. In 2005, alcohol dependence and misuse was estimated to cost the US economy approximately 220 billion dollars per year, more than cancer and obesity. Society and culture The various health problems associated with long-term alcohol consumption are generally perceived as detrimental to society; for example, money due to lost labor-hours, medical costs due to injuries due to drunkenness and organ damage from long-term use, and secondary treatment costs, such as the costs of rehabilitation facilities and detoxification centers. Alcohol use is a major contributing factor for head injuries, motor vehicle injuries (27%), interpersonal violence (18%), suicides (18%), and epilepsy (13%). Beyond the financial costs that alcohol consumption imposes, there are also significant social costs to both the alcoholic and their family and friends. For instance, alcohol consumption by a pregnant woman can lead to an incurable and damaging condition known as fetal alcohol syndrome, which often results in cognitive deficits, mental health problems, an inability to live independently and an increased risk of criminal behaviour, all of which can cause emotional stress for parents and caregivers. Estimates of the economic costs of alcohol misuse, collected by the World Health Organization, vary from 1–6% of a country's GDP. One Australian estimate pegged alcohol's social costs at 24% of all drug misuse costs; a similar Canadian study concluded alcohol's share was 41%. One study quantified the cost to the UK of all forms of alcohol misuse in 2001 as £18.5–20 billion. All economic costs in the United States in 2006 have been estimated at $223.5 billion. The idea of hitting rock bottom refers to an experience of stress that can be attributed to alcohol misuse. There is no single definition for this idea, and people may identify their own lowest points in terms of lost jobs, lost relationships, health problems, legal problems, or other consequences of alcohol misuse. The concept is promoted by 12-step recovery groups and researchers using the transtheoretical model of motivation for behavior change. The first use of this slang phrase in the formal medical literature appeared in a 1965 review in the British Medical Journal, which said that some men refused treatment until they "hit rock bottom", but that treatment was generally more successful for "the alcohol addict who has friends and family to support him" than for impoverished and homeless addicts. Stereotypes of alcoholics are often found in fiction and popular culture. The "town drunk" is a stock character in Western popular culture. Stereotypes of drunkenness may be based on racism or xenophobia, as in the fictional depiction of the Irish as heavy drinkers. Studies by social psychologists Stivers and Greeley attempt to document the perceived prevalence of high alcohol consumption amongst the Irish in America. Alcohol consumption is relatively similar between many European cultures, the United States, and Australia. In Asian countries that have a high gross domestic product, there is heightened drinking compared to other Asian countries, but it is nowhere near as high as it is in other countries like the United States. It is also inversely seen, with countries that have very low gross domestic product showing high alcohol consumption. In a study done on Korean immigrants in Canada, they reported alcohol was typically an integral part of their meal but is the only time solo drinking should occur. They also generally believe alcohol is necessary at any social event, as it helps conversations start. Peyote, a psychoactive agent, has even shown promise in treating alcoholism. Alcohol had actually replaced peyote as Native Americans' psychoactive agent of choice in rituals when peyote was outlawed.

Abstraction

Abstraction is a conceptual process wherein general rules and concepts are derived from the usage and classification of specific examples, literal (real or concrete) signifiers, first principles, or other methods. "An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts and connects any related concepts as a group, field, or category. Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only those aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior, excluding but not eliminating the other phenomenal and cognitive characteristics of that particular ball. In a type–token distinction, a type (e.g., a 'ball') is more abstract than its tokens (e.g., 'that leather soccer ball'). Abstraction in its secondary use is a material process, discussed in the themes below. Origins Thinking in abstractions is considered by anthropologists, archaeologists, and sociologists to be one of the key traits in modern human behaviour, which is believed to have developed between 50,000 and 100,000 years ago. Its development is likely to have been closely connected with the development of human language, which (whether spoken or written) appears to both involve and facilitate abstract thinking. History Abstraction involves induction of ideas or the synthesis of particular facts into one general theory about something. It is the opposite of specification, which is the analysis or breaking-down of a general idea or abstraction into concrete facts. Abstraction can be illustrated by Francis Bacon's Novum Organum (1620), a book of modern scientific philosophy written in the late Jacobean era of England to encourage modern thinkers to collect specific facts before making any generalizations. Bacon used and promoted induction as an abstraction tool; it complemented but was distinct from the ancient deductive-thinking approach that had dominated the intellectual world since the times of Greek philosophers like Thales, Anaximander, and Aristotle. Thales (–546 BCE) believed that everything in the universe comes from one main substance, water. He deduced or specified from a general idea, "everything is water," to the specific forms of water such as ice, snow, fog, and rivers. Modern scientists used the approach of abstraction (going from particular facts collected into one general idea). Newton (1642–1727) derived the motion of the planets from Copernicus' (1473–1543) simplification, that the sun is the center of our solar system; Kepler (1571–1630) compressed thousands of measurements into one expression to finally conclude that Mars moves in an elliptical orbit about the sun; Galileo (1564–1642) repeated one hundred specific experiments into the law of falling bodies. Themes Compression An abstraction can be seen as a compression process, mapping multiple different pieces of constituent data to a single piece of abstract data; based on similarities in the constituent data, for example, many different physical cats map to the abstraction "CAT". This conceptual scheme emphasizes the inherent equality of both constituent and abstract data, thus avoiding problems arising from the distinction between "abstract" and "concrete". In this sense the process of abstraction entails the identification of similarities between objects, and the process of associating these objects with an abstraction (which is itself an object). For example, picture 1 below illustrates the concrete relationship "Cat sits on Mat". Chains of abstractions can be construed, moving from neural impulses arising from sensory perception to basic abstractions such as color or shape, to experiential abstractions such as a specific cat, to semantic abstractions such as the "idea" of a CAT, to classes of objects such as "mammals" and even categories such as "object" as opposed to "action". For example, graph 1 below expresses the abstraction "agent sits on location". This conceptual scheme entails no specific hierarchical taxonomy (such as the one mentioned involving cats and mammals), only a progressive exclusion of detail. Instantiation Non-existent things in any particular place and time are often seen as abstract. By contrast, instances, or members, of such an abstract thing might exist in many different places and times. Those abstract things are then said to be multiply instantiated, in the sense of picture 1, picture 2, etc., shown below. It is not sufficient, however, to define abstract ideas as those that can be instantiated and to define abstraction as the movement in the opposite direction to instantiation. Doing so would make the concepts "cat" and "telephone" abstract ideas since despite their varying appearances, a particular cat or a particular telephone is an instance of the concept "cat" or the concept "telephone". Although the concepts "cat" and "telephone" are abstractions, they are not abstract in the sense of the objects in graph 1 below. We might look at other graphs, in a progression from cat to mammal to animal, and see that animal is more abstract than mammal; but on the other hand mammal is a harder idea to express, certainly in relation to marsupial or monotreme. Perhaps confusingly, some philosophies refer to tropes (instances of properties) as abstract particulars—e.g., the particular redness of a particular apple is an abstract particular. This is similar to qualia and sumbebekos. Material process Still retaining the primary meaning of '' or 'to draw away from', the abstraction of money, for example, works by drawing away from the particular value of things allowing completely incommensurate objects to be compared (see the section on 'Physicality' below). Karl Marx's writing on the commodity abstraction recognizes a parallel process. The state (polity) as both concept and material practice exemplifies the two sides of this process of abstraction. Conceptually, 'the current concept of the state is an abstraction from the much more concrete early-modern use as the standing or status of the prince, his visible estates'. At the same time, materially, the 'practice of statehood is now constitutively and materially more abstract than at the time when princes ruled as the embodiment of extended power'. Ontological status The way that physical objects, like rocks and trees, have being differs from the way that properties of abstract concepts or relations have being, for example the way the concrete, particular, individuals pictured in picture 1 exist differs from the way the concepts illustrated in graph 1 exist. That difference accounts for the ontological usefulness of the word "abstract". The word applies to properties and relations to mark the fact that, if they exist, they do not exist in space or time, but that instances of them can exist, potentially in many different places and times. Abstraction this, abstraction Physicality A physical object (a possible referent of a concept or word) is considered concrete (not abstract) if it is a particular individual that occupies a particular place and time. However, in the secondary sense of the term 'abstraction', this physical object can carry materially abstracting processes. For example, record-keeping aids throughout the Fertile Crescent included calculi (clay spheres, cones, etc.) which represented counts of items, probably livestock or grains, sealed in containers. According to , these clay containers contained tokens, the total of which were the count of objects being transferred. The containers thus served as something of a bill of lading or an accounts book. In order to avoid breaking open the containers for the count, marks were placed on the outside of the containers. These physical marks, in other words, acted as material abstractions of a materially abstract process of accounting, using conceptual abstractions (numbers) to communicate its meaning. Abstract things are sometimes defined as those things that do not exist in reality or exist only as sensory experiences, like the color red. That definition, however, suffers from the difficulty of deciding which things are real (i.e. which things exist in reality). For example, it is difficult to agree to whether concepts like God, the number three, and goodness are real, abstract, or both. An approach to resolving such difficulty is to use predicates as a general term for whether things are variously real, abstract, concrete, or of a particular property (e.g., good). Questions about the properties of things are then propositions about predicates, which propositions remain to be evaluated by the investigator. In the graph 1 below, the graphical relationships like the arrows joining boxes and ellipses might denote predicates. Referencing and referring Abstractions sometimes have ambiguous referents. For example, "happiness" can mean experiencing various positive emotions, but can also refer to life satisfaction and subjective well-being. Likewise, "architecture" refers not only to the design of safe, functional buildings, but also to elements of creation and innovation which aim at elegant solutions to construction problems, to the use of space, and to the attempt to evoke an emotional response in the builders, owners, viewers and users of the building. Simplification and ordering Abstraction uses a strategy of simplification, wherein formerly concrete details are left ambiguous, vague, or undefined; thus effective communication about things in the abstract requires an intuitive or common experience between the communicator and the communication recipient. This is true for all verbal/abstract communication. For example, many different things can be red. Likewise, many things sit on surfaces (as in picture 1, to the right). The property of redness and the relation sitting-on are therefore abstractions of those objects. Specifically, the conceptual diagram graph 1 identifies only three boxes, two ellipses, and four arrows (and their five labels), whereas the picture 1 shows much more pictorial detail, with the scores of implied relationships as implicit in the picture rather than with the nine explicit details in the graph. Graph 1 details some explicit relationships between the objects of the diagram. For example, the arrow between the agent and CAT:Elsie depicts an example of an is-a relationship, as does the arrow between the location and the MAT. The arrows between the gerund/present participle SITTING and the nouns agent and location express the diagram's basic relationship; "agent is SITTING on location"; Elsie is an instance of CAT. Although the description sitting-on (graph 1) is more abstract than the graphic image of a cat sitting on a mat (picture 1), the delineation of abstract things from concrete things is somewhat ambiguous; this ambiguity or vagueness is characteristic of abstraction. Thus something as simple as a newspaper might be specified to six levels, as in Douglas Hofstadter's illustration of that ambiguity, with a progression from abstract to concrete in Gödel, Escher, Bach (1979): An abstraction can thus encapsulate each of these levels of detail with no loss of generality. But perhaps a detective or philosopher/scientist/engineer might seek to learn about something, at progressively deeper levels of detail, to solve a crime or a puzzle. Thought processes In philosophical terminology, abstraction is the thought process wherein ideas are distanced from objects. But an idea can be symbolized. As used in different disciplines In art Typically, abstraction is used in the arts as a synonym for abstract art in general. Strictly speaking, it refers to art unconcerned with the literal depiction of things from the visible world—it can, however, refer to an object or image which has been distilled from the real world, or indeed, another work of art. Artwork that reshapes the natural world for expressive purposes is called abstract; that which derives from, but does not imitate a recognizable subject is called nonobjective abstraction. In the 20th century the trend toward abstraction coincided with advances in science, technology, and changes in urban life, eventually reflecting an interest in psychoanalytic theory. Later still, abstraction was manifest in more purely formal terms, such as color, freedom from objective context, and a reduction of form to basic geometric designs. In computer science Computer scientists use abstraction to make models that can be used and re-used without having to re-write all the program code for each new application on every different type of computer. They communicate their solutions with the computer by writing source code in some particular computer language which can be translated into machine code for different types of computers to execute. Abstraction allows program designers to separate a framework (categorical concepts related to computing problems) from specific instances which implement details. This means that the program code can be written so that code does not have to depend on the specific details of supporting applications, operating system software, or hardware, but on a categorical concept of the solution. A solution to the problem can then be integrated into the system framework with minimal additional work. This allows programmers to take advantage of another programmer's work, while requiring only an abstract understanding of the implementation of another's work, apart from the problem that it solves. In general semantics Abstractions and levels of abstraction play an important role in the theory of general semantics originated by Alfred Korzybski. Anatol Rapoport wrote "Abstracting is a mechanism by which an infinite variety of experiences can be mapped on short noises (words)." In history Francis Fukuyama defines history as "a deliberate attempt of abstraction in which we separate out important from unimportant events". In linguistics Researchers in linguistics frequently apply abstraction so as to allow an analysis of the phenomena of language at the desired level of detail. A commonly used abstraction, the phoneme, abstracts speech sounds in such a way as to neglect details that cannot serve to differentiate meaning. Other analogous kinds of abstractions (sometimes called "emic units") considered by linguists include morphemes, graphemes, and lexemes. Abstraction also arises in the relation between syntax, semantics, and pragmatics. Pragmatics involves considerations that make reference to the user of the language; semantics considers expressions and what they denote (the designata) abstracted from the language user; and syntax considers only the expressions themselves, abstracted from the designate. In mathematics Abstraction in mathematics is the process of extracting the underlying structures, patterns or properties of a mathematical concept or object, removing any dependence on real-world objects with which it might originally have been connected, and generalizing it so that it has wider applications or matching among other abstract descriptions of equivalent phenomena. The advantages of abstraction in mathematics are: It reveals deep connections between different areas of mathematics. Known results in one area can suggest conjectures in another related area. Techniques and methods from one area can be applied to prove results in other related area. Patterns from one mathematical object can be generalized to other similar objects in the same class. The main disadvantage of abstraction is that highly abstract concepts are more difficult to learn, and might require a degree of mathematical maturity and experience before they can be assimilated. In music In music, the term abstraction can be used to describe improvisatory approaches to interpretation, and may sometimes indicate abandonment of tonality. Atonal music has no key signature, and is characterized by the exploration of internal numeric relationships. In neurology A recent meta-analysis suggests that the verbal system has a greater engagement with abstract concepts when the perceptual system is more engaged in processing concrete concepts. This is because abstract concepts elicit greater brain activity in the inferior frontal gyrus and middle temporal gyrus compared to concrete concepts which elicit greater activity in the posterior cingulate, precuneus, fusiform gyrus, and parahippocampal gyrus. Other research into the human brain suggests that the left and right hemispheres differ in their handling of abstraction. For example, one meta-analysis reviewing human brain lesions has shown a left hemisphere bias during tool usage. In philosophy Abstraction in philosophy is the process (or, to some, the alleged process) in concept formation of recognizing some set of common features in individuals, and on that basis forming a concept of that feature. The notion of abstraction is important to understanding some philosophical controversies surrounding empiricism and the problem of universals. It has also recently become popular in formal logic under predicate abstraction. Another philosophical tool for the discussion of abstraction is thought space. John Locke defined abstraction in An Essay Concerning Human Understanding: 'So words are used to stand as outward marks of our internal ideas, which are taken from particular things; but if every particular idea that we take in had its own special name, there would be no end to names. To prevent this, the mind makes particular ideas received from particular things become general; which it does by considering them as they are in the mind—mental appearances—separate from all other existences, and from the circumstances of real existence, such as time, place, and so on. This procedure is called abstraction. In it, an idea taken from a particular thing becomes a general representative of all of the same kind, and its name becomes a general name that is applicable to any existing thing that fits that abstract idea.' (2.11.9) In psychology Carl Jung's definition of abstraction broadened its scope beyond the thinking process to include exactly four mutually exclusive, different complementary psychological functions: sensation, intuition, feeling, and thinking. Together they form a structural totality of the differentiating abstraction process. Abstraction operates in one of these functions when it excludes the simultaneous influence of the other functions and other irrelevancies, such as emotion. Abstraction requires selective use of this structural split of abilities in the psyche. The opposite of abstraction is concretism. Abstraction is one of Jung's 57 definitions in Chapter XI of Psychological Types. In social theory Social theorists deal with abstraction both as an ideational and as a material process. Alfred Sohn-Rethel (1899–1990) asked: "Can there be abstraction other than by thought?" He used the example of commodity abstraction to show that abstraction occurs in practice as people create systems of abstract exchange that extend beyond the immediate physicality of the object and yet have real and immediate consequences. This work was extended through the 'Constitutive Abstraction' approach of writers associated with the Journal Arena. Two books that have taken this theme of the abstraction of social relations as an organizing process in human history are Nation Formation: Towards a Theory of Abstract Community (1996) and an associated volume published in 2006, Globalism, Nationalism, Tribalism: Bringing Theory Back In. These books argue that a nation is an abstract community bringing together strangers who will never meet as such; thus constituting materially real and substantial, but abstracted and mediated relations. The books suggest that contemporary processes of globalization and mediatization have contributed to materially abstracting relations between people, with major consequences for how humans live their lives. One can readily argue that abstraction is an elementary methodological tool in several disciplines of social science. These disciplines have definite and different concepts of "man" that highlight those aspects of man and his behaviour by idealization that are relevant for the given human science. For example, is the man as sociology abstracts and idealizes it, depicting man as a social being. Moreover, we could talk about (the man who can extend his biologically determined intelligence thanks to new technologies), or (who is simply creative). Abstraction (combined with Weberian idealization) plays a crucial role in economics - hence abstractions such as "the market" and the generalized concept of "business". Breaking away from directly experienced reality was a common trend in 19th-century sciences (especially physics), and this was the effort which fundamentally determined the way economics tried (and still tries) to approach the economic aspects of social life. It is abstraction we meet in the case of both Newton's physics and the neoclassical theory, since the goal was to grasp the unchangeable and timeless essence of phenomena. For example, Newton created the concept of the material point by following the abstraction method so that he abstracted from the dimension and shape of any perceptible object, preserving only inertial and translational motion. Material point is the ultimate and common feature of all bodies. Neoclassical economists created the indefinitely abstract notion of homo economicus by following the same procedure. Economists abstract from all individual and personal qualities in order to get to those characteristics that embody the essence of economic activity. Eventually, it is the substance of the economic man that they try to grasp. Any characteristic beyond it only disturbs the functioning of this essential core.

Abelian group

In mathematics, an abelian group, also called a commutative group, is a group in which the result of applying the group operation to two group elements does not depend on the order in which they are written. That is, the group operation is commutative. With addition as an operation, the integers and the real numbers form abelian groups, and the concept of an abelian group may be viewed as a generalization of these examples. Abelian groups are named after early 19th century mathematician Niels Henrik Abel. The concept of an abelian group underlies many fundamental algebraic structures, such as fields, rings, vector spaces, and algebras. The theory of abelian groups is generally simpler than that of their non-abelian counterparts, and finite abelian groups are very well understood and fully classified. Definition An abelian group is a set , together with an operation that combines any two elements and of to form another element of denoted . The symbol is a general placeholder for a concretely given operation. To qualify as an abelian group, the set and operation, , must satisfy four requirements known as the abelian group axioms (some authors include in the axioms some properties that belong to the definition of an operation: namely that the operation is defined for any ordered pair of elements of , that the result is well-defined, and that the result belongs to ): Associativity For all , , and in , the equation holds. Identity element There exists an element in , such that for all elements in , the equation holds. Inverse element For each in there exists an element in such that , where is the identity element. Commutativity For all , in , . A group in which the group operation is not commutative is called a "non-abelian group" or "non-commutative group". Facts Notation There are two main notational conventions for abelian groups – additive and multiplicative. Generally, the multiplicative notation is the usual notation for groups, while the additive notation is the usual notation for modules and rings. The additive notation may also be used to emphasize that a particular group is abelian, whenever both abelian and non-abelian groups are considered, some notable exceptions being near-rings and partially ordered groups, where an operation is written additively even when non-abelian. Multiplication table To verify that a finite group is abelian, a table (matrix) – known as a Cayley table – can be constructed in a similar fashion to a multiplication table. If the group is under the the entry of this table contains the product . The group is abelian if and only if this table is symmetric about the main diagonal. This is true since the group is abelian iff for all , which is iff the entry of the table equals the entry for all , i.e. the table is symmetric about the main diagonal. Examples For the integers and the operation addition , denoted , the operation + combines any two integers to form a third integer, addition is associative, zero is the additive identity, every integer has an additive inverse, , and the addition operation is commutative since for any two integers and . Every cyclic group is abelian, because if , are in , then . Thus the integers, , form an abelian group under addition, as do the integers modulo , . Every ring is an abelian group with respect to its addition operation. In a commutative ring the invertible elements, or units, form an abelian multiplicative group. In particular, the real numbers are an abelian group under addition, and the nonzero real numbers are an abelian group under multiplication. Every subgroup of an abelian group is normal, so each subgroup gives rise to a quotient group. Subgroups, quotients, and direct sums of abelian groups are again abelian. The finite simple abelian groups are exactly the cyclic groups of prime order. The concepts of abelian group and -module agree. More specifically, every -module is an abelian group with its operation of addition, and every abelian group is a module over the ring of integers in a unique way. In general, matrices, even invertible matrices, do not form an abelian group under multiplication because matrix multiplication is generally not commutative. However, some groups of matrices are abelian groups under matrix multiplication – one example is the group of rotation matrices. Historical remarks Camille Jordan named abelian groups after Norwegian mathematician Niels Henrik Abel, as Abel had found that the commutativity of the group of a polynomial implies that the roots of the polynomial can be calculated by using radicals. Properties If is a natural number and is an element of an abelian group written additively, then can be defined as ( summands) and . In this way, becomes a module over the ring of integers. In fact, the modules over can be identified with the abelian groups. Theorems about abelian groups (i.e. modules over the principal ideal domain ) can often be generalized to theorems about modules over an arbitrary principal ideal domain. A typical example is the classification of finitely generated abelian groups which is a specialization of the structure theorem for finitely generated modules over a principal ideal domain. In the case of finitely generated abelian groups, this theorem guarantees that an abelian group splits as a direct sum of a torsion group and a free abelian group. The former may be written as a direct sum of finitely many groups of the form for prime, and the latter is a direct sum of finitely many copies of . If are two group homomorphisms between abelian groups, then their sum , defined by , is again a homomorphism. (This is not true if is a non-abelian group.) The set of all group homomorphisms from to is therefore an abelian group in its own right. Somewhat akin to the dimension of vector spaces, every abelian group has a rank. It is defined as the maximal cardinality of a set of linearly independent (over the integers) elements of the group. Finite abelian groups and torsion groups have rank zero, and every abelian group of rank zero is a torsion group. The integers and the rational numbers have rank one, as well as every nonzero additive subgroup of the rationals. On the other hand, the multiplicative group of the nonzero rationals has an infinite rank, as it is a free abelian group with the set of the prime numbers as a basis (this results from the fundamental theorem of arithmetic). The center of a group is the set of elements that commute with every element of . A group is abelian if and only if it is equal to its center . The center of a group is always a characteristic abelian subgroup of . If the quotient group of a group by its center is cyclic then is abelian. Finite abelian groups Cyclic groups of integers modulo , , were among the first examples of groups. It turns out that an arbitrary finite abelian group is isomorphic to a direct sum of finite cyclic groups of prime power order, and these orders are uniquely determined, forming a complete system of invariants. The automorphism group of a finite abelian group can be described directly in terms of these invariants. The theory had been first developed in the 1879 paper of Georg Frobenius and Ludwig Stickelberger and later was both simplified and generalized to finitely generated modules over a principal ideal domain, forming an important chapter of linear algebra. Any group of prime order is isomorphic to a cyclic group and therefore abelian. Any group whose order is a square of a prime number is also abelian. In fact, for every prime number there are (up to isomorphism) exactly two groups of order , namely and . Classification The fundamental theorem of finite abelian groups states that every finite abelian group can be expressed as the direct sum of cyclic subgroups of prime-power order; it is also known as the basis theorem for finite abelian groups. Moreover, automorphism groups of cyclic groups are examples of abelian groups. This is generalized by the fundamental theorem of finitely generated abelian groups, with finite groups being the special case when G has zero rank; this in turn admits numerous further generalizations. The classification was proven by Leopold Kronecker in 1870, though it was not stated in modern group-theoretic terms until later, and was preceded by a similar classification of quadratic forms by Carl Friedrich Gauss in 1801; see history for details. The cyclic group of order is isomorphic to the direct sum of and if and only if and are coprime. It follows that any finite abelian group is isomorphic to a direct sum of the form in either of the following canonical ways: the numbers are powers of (not necessarily distinct) primes, or divides , which divides , and so on up to . For example, can be expressed as the direct sum of two cyclic subgroups of order 3 and 5: . The same can be said for any abelian group of order 15, leading to the remarkable conclusion that all abelian groups of order 15 are isomorphic. For another example, every abelian group of order 8 is isomorphic to either (the integers 0 to 7 under addition modulo 8), (the odd integers 1 to 15 under multiplication modulo 16), or . See also list of small groups for finite abelian groups of order 30 or less. Automorphisms One can apply the fundamental theorem to count (and sometimes determine) the automorphisms of a given finite abelian group . To do this, one uses the fact that if splits as a direct sum of subgroups of coprime order, then Given this, the fundamental theorem shows that to compute the automorphism group of it suffices to compute the automorphism groups of the Sylow -subgroups separately (that is, all direct sums of cyclic subgroups, each with order a power of ). Fix a prime and suppose the exponents of the cyclic factors of the Sylow -subgroup are arranged in increasing order: for some . One needs to find the automorphisms of One special case is when , so that there is only one cyclic prime-power factor in the Sylow -subgroup . In this case the theory of automorphisms of a finite cyclic group can be used. Another special case is when is arbitrary but for . Here, one is considering to be of the form so elements of this subgroup can be viewed as comprising a vector space of dimension over the finite field of elements . The automorphisms of this subgroup are therefore given by the invertible linear transformations, so where is the appropriate general linear group. This is easily shown to have order In the most general case, where the and are arbitrary, the automorphism group is more difficult to determine. It is known, however, that if one defines and then one has in particular , , and One can check that this yields the orders in the previous examples as special cases (see Hillar, C., & Rhea, D.). Finitely generated abelian groups An abelian group is finitely generated if it contains a finite set of elements (called generators) such that every element of the group is a linear combination with integer coefficients of elements of . Let be a free abelian group with basis There is a unique group homomorphism such that This homomorphism is surjective, and its kernel is finitely generated (since integers form a Noetherian ring). Consider the matrix with integer entries, such that the entries of its th column are the coefficients of the th generator of the kernel. Then, the abelian group is isomorphic to the cokernel of linear map defined by . Conversely every integer matrix defines a finitely generated abelian group. It follows that the study of finitely generated abelian groups is totally equivalent with the study of integer matrices. In particular, changing the generating set of is equivalent with multiplying on the left by a unimodular matrix (that is, an invertible integer matrix whose inverse is also an integer matrix). Changing the generating set of the kernel of is equivalent with multiplying on the right by a unimodular matrix. The Smith normal form of is a matrix where and are unimodular, and is a matrix such that all non-diagonal entries are zero, the non-zero diagonal entries are the first ones, and is a divisor of for . The existence and the shape of the Smith normal proves that the finitely generated abelian group is the direct sum where is the number of zero rows at the bottom of (and also the rank of the group). This is the fundamental theorem of finitely generated abelian groups. The existence of algorithms for Smith normal form shows that the fundamental theorem of finitely generated abelian groups is not only a theorem of abstract existence, but provides a way for computing expression of finitely generated abelian groups as direct sums. Infinite abelian groups The simplest infinite abelian group is the infinite cyclic group . Any finitely generated abelian group is isomorphic to the direct sum of copies of and a finite abelian group, which in turn is decomposable into a direct sum of finitely many cyclic groups of prime power orders. Even though the decomposition is not unique, the number , called the rank of , and the prime powers giving the orders of finite cyclic summands are uniquely determined. By contrast, classification of general infinitely generated abelian groups is far from complete. Divisible groups, i.e. abelian groups in which the equation admits a solution for any natural number and element of , constitute one important class of infinite abelian groups that can be completely characterized. Every divisible group is isomorphic to a direct sum, with summands isomorphic to and Prüfer groups for various prime numbers , and the cardinality of the set of summands of each type is uniquely determined. Moreover, if a divisible group is a subgroup of an abelian group then admits a direct complement: a subgroup of such that . Thus divisible groups are injective modules in the category of abelian groups, and conversely, every injective abelian group is divisible (Baer's criterion). An abelian group without non-zero divisible subgroups is called reduced. Two important special classes of infinite abelian groups with diametrically opposite properties are torsion groups and torsion-free groups, exemplified by the groups (periodic) and (torsion-free). Torsion groups An abelian group is called periodic or torsion, if every element has finite order. A direct sum of finite cyclic groups is periodic. Although the converse statement is not true in general, some special cases are known. The first and second Prüfer theorems state that if is a periodic group, and it either has a bounded exponent, i.e., for some natural number , or is countable and the -heights of the elements of are finite for each , then is isomorphic to a direct sum of finite cyclic groups. The cardinality of the set of direct summands isomorphic to in such a decomposition is an invariant of . These theorems were later subsumed in the Kulikov criterion. In a different direction, Helmut Ulm found an extension of the second Prüfer theorem to countable abelian -groups with elements of infinite height: those groups are completely classified by means of their Ulm invariants. Torsion-free and mixed groups An abelian group is called torsion-free if every non-zero element has infinite order. Several classes of torsion-free abelian groups have been studied extensively: Free abelian groups, i.e. arbitrary direct sums of Cotorsion and algebraically compact torsion-free groups such as the -adic integers Slender groups An abelian group that is neither periodic nor torsion-free is called mixed. If is an abelian group and is its torsion subgroup, then the factor group is torsion-free. However, in general the torsion subgroup is not a direct summand of , so is not isomorphic to . Thus the theory of mixed groups involves more than simply combining the results about periodic and torsion-free groups. The additive group of integers is torsion-free -module. Invariants and classification One of the most basic invariants of an infinite abelian group is its rank: the cardinality of the maximal linearly independent subset of . Abelian groups of rank 0 are precisely the periodic groups, while torsion-free abelian groups of rank 1 are necessarily subgroups of and can be completely described. More generally, a torsion-free abelian group of finite rank is a subgroup of . On the other hand, the group of -adic integers is a torsion-free abelian group of infinite -rank and the groups with different are non-isomorphic, so this invariant does not even fully capture properties of some familiar groups. The classification theorems for finitely generated, divisible, countable periodic, and rank 1 torsion-free abelian groups explained above were all obtained before 1950 and form a foundation of the classification of more general infinite abelian groups. Important technical tools used in classification of infinite abelian groups are pure and basic subgroups. Introduction of various invariants of torsion-free abelian groups has been one avenue of further progress. See the books by Irving Kaplansky, László Fuchs, Phillip Griffith, and David Arnold, as well as the proceedings of the conferences on Abelian Group Theory published in Lecture Notes in Mathematics for more recent findings. Additive groups of rings The additive group of a ring is an abelian group, but not all abelian groups are additive groups of rings (with nontrivial multiplication). Some important topics in this area of study are: Tensor product A.L.S. Corner's results on countable torsion-free groups Shelah's work to remove cardinality restrictions Burnside ring Relation to other mathematical topics Many large abelian groups possess a natural topology, which turns them into topological groups. The collection of all abelian groups, together with the homomorphisms between them, forms the category , the prototype of an abelian category. proved that the first-order theory of abelian groups, unlike its non-abelian counterpart, is decidable. Most algebraic structures other than Boolean algebras are undecidable. There are still many areas of current research: Amongst torsion-free abelian groups of finite rank, only the finitely generated case and the rank 1 case are well understood; There are many unsolved problems in the theory of infinite-rank torsion-free abelian groups; While countable torsion abelian groups are well understood through simple presentations and Ulm invariants, the case of countable mixed groups is much less mature. Many mild extensions of the first-order theory of abelian groups are known to be undecidable. Finite abelian groups remain a topic of research in computational group theory. Moreover, abelian groups of infinite order lead, quite surprisingly, to deep questions about the set theory commonly assumed to underlie all of mathematics. Take the Whitehead problem: are all Whitehead groups of infinite order also free abelian groups? In the 1970s, Saharon Shelah proved that the Whitehead problem is: Undecidable in ZFC (Zermelo–Fraenkel axioms), the conventional axiomatic set theory from which nearly all of present-day mathematics can be derived. The Whitehead problem is also the first question in ordinary mathematics proved undecidable in ZFC; Undecidable even if ZFC is augmented by taking the generalized continuum hypothesis as an axiom; Positively answered if ZFC is augmented with the axiom of constructibility (see statements true in L). A note on typography Among mathematical adjectives derived from the proper name of a mathematician, the word "abelian" is rare in that it is often spelled with a lowercase a, rather than an uppercase A, the lack of capitalization being a tacit acknowledgment not only of the degree to which Abel's name has been institutionalized but also of how ubiquitous in modern mathematics are the concepts introduced by him.

Austria-Hungary

Austria-Hungary, formally known as the Austro-Hungarian Monarchy, often referred to as the Austro-Hungarian Empire or the Dual Monarchy, was a multi-national constitutional monarchy in Central Europe between 1867 and 1918. Austria-Hungary was a military and diplomatic alliance of two sovereign states with a single monarch who was titled both Emperor of Austria and King of Hungary. Austria-Hungary constituted the last phase in the constitutional evolution of the Habsburg monarchy: it was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after Hungary terminated the union with Austria on 31 October 1918. One of Europe's major powers at the time, Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at and the third-most populous (after Russia and the German Empire). The Empire built up the fourth-largest machine-building industry in the world, after the United States, Germany and the United Kingdom. Austria-Hungary also became the world's third-largest manufacturer and exporter of electric home appliances, electric industrial appliances, and power generation apparatus for power plants, after the United States and the German Empire, and it constructed Europe's second-largest railway network after the German Empire. With the exception of the territory of Bosnian Condominium, Empire of Austria and the Kingdom of Hungary were separate sovereign countries in international law. Thus separate representatives from Austria and Hungary signed peace treaties agreeing to territorial changes, for example the Treaty of Saint-Germain and the Treaty of Trianon. Citizenship and passports were also separate. At its core was the dual monarchy which was a real union between Cisleithania, the northern and western parts of the former Austrian Empire, and the Kingdom of Hungary. Following the 1867 reforms, the Austrian and Hungarian states were co-equal in power. The two countries conducted unified diplomatic and defence policies. For these purposes, "common" ministries of foreign affairs and defence were maintained under the monarch's direct authority, as was a third finance ministry responsible only for financing the two "common" portfolios. A third component of the union was the Kingdom of Croatia-Slavonia, an autonomous region under the Hungarian crown, which negotiated the Croatian–Hungarian Settlement in 1868. After 1878, Bosnia and Herzegovina came under Austro-Hungarian joint military and civilian rule until it was fully annexed in 1908, provoking the Bosnian crisis. Austria-Hungary was one of the Central Powers in World War I, which began with an Austro-Hungarian war declaration on the Kingdom of Serbia on 28 July 1914. It was already effectively dissolved by the time the military authorities signed the armistice of Villa Giusti on 3 November 1918. The Kingdom of Hungary and the First Austrian Republic were treated as its successors de jure, whereas the independence of the West Slavs and South Slavs of the Empire as the First Czechoslovak Republic, the Second Polish Republic, and the Kingdom of Yugoslavia, respectively, and most of the territorial demands of the Kingdom of Romania and the Kingdom of Italy were also recognized by the victorious powers in 1920. Name and terminology The realm's official name was in and in (), though in international relations Austria–Hungary was used (; ). The Austrians also used the names () (in detail ; ) and Danubian Monarchy (; ) or Dual Monarchy (; ) and The Double Eagle (; ), but none of these became widespread either in Hungary or elsewhere. The realm's full name used in the internal administration was The Kingdoms and Lands Represented in the Imperial Council and the Lands of the Holy Hungarian Crown of St. Stephen. German: Hungarian: From 1867 onwards, the abbreviations heading the names of official institutions in Austria–Hungary reflected their responsibility: ( or Imperial and Royal) was the label for institutions common to both parts of the monarchy, e.g., the (War Fleet) and, during the war, the (Army). The common army changed its label from to only in 1889 at the request of the Hungarian government. () or Imperial-Royal was the term for institutions of Cisleithania (Austria); "royal" in this label referred to the Crown of Bohemia. () or () ("Royal Hungarian") referred to Transleithania, the lands of the Hungarian crown. In the Kingdom of Croatia and Slavonia, its autonomous institutions hold k. () ("Royal") as according to the Croatian–Hungarian Settlement, the only official language in Croatia and Slavonia was Croatian, and those institutions were "only" Croatian. Following a decision of Franz Joseph I in 1868, the realm bore the official name Austro-Hungarian Monarchy/Realm (; ) in its international relations. It was often contracted to the Dual Monarchy in English or simply referred to as Austria. History Formation and Background Ever since the Hapsburgs ascended to the throne of Kingdom of Hungary, the kingdom had always enjoyed a great degree of autonomy. In the revolutions of 1848, the Kingdom of Hungary in the Austrian Empire called for greater self-government and later even independence from the Hapsburg Empire. This was crushed militarily by the Austrians with Russian help, and the traditional autonomy that the Hungarians had enjoyed was replaced with absolutist rule from Vienna. However, this only further increased Hungarian resentment of Hapsburg dominion. In the 1860's, the Empire faced two severe defeats: its loss in the Second Italian War of Independence broke its dominion over much of Italy, while defeat in the Austro-Prussian War of 1866 led to the dissolution of the German Confederation (of which the Hapsburg emperor was the hereditary president) and the exclusion of Austria from German affairs. These twin defeats gave the Hungarians the opportunity to remove the shackles of absolutist rule. Realizing the need to compromise with Hungary in order to retain its great power status, the central government in Vienna began negotiations with the Hungarian nobility, led by Ferenc Deák. On 20 March 1867, the newly re-established Hungarian parliament at Pest started to negotiate the new laws to be accepted on 30 March. However, Hungarian leaders received the Emperor's formal coronation as King of Hungary on 8 June as a necessity for the laws to be enacted within the lands of the Holy Crown of Hungary. On 28 July, Franz Joseph, in his new capacity as King of Hungary, approved and promulgated the new laws, which officially gave birth to the Dual Monarchy. 1866–1878: beyond Kleindeutschland The Austro-Prussian war was ended by the Peace of Prague (1866) which settled ythe German Question in favor of a Lesser German Solution. Count Friedrich Ferdinand von Beust, who was the foreign secretary from 1866–1871, hated the Prussian leader, Otto von Bismarck, who had repeatedly outmaneuvered him. Beust looked to France for avenging Austria's defeat and attempted to negotiate with Emperor Napoleon III of France and Italy for an anti-Prussian alliance, but no terms could be reached. The decisive victory of Prusso-German armies in the Franco-Prussian war and the subsequent founding of the German Empire ended all hope of re establishing Austrian dominance in Germany and Beust retired. After being forced out of Germany and Italy, the Dual Monarchy turned to the Balkans, which were in tumult as nationalistic movements were gaining strength and demanding independence. Both Russia and Austria–Hungary saw an opportunity to expand in this region. Russia took on the role of protector of Slavs and Orthodox Christians. Austria envisioned a multi-ethnic, religiously diverse empire under Vienna's control. Count Gyula Andrássy, a Hungarian who was Foreign Minister (1871–1879), made the centerpiece of his policy one of opposition to Russian expansion in the Balkans and blocking Serbian ambitions to dominate a new South Slav federation. He wanted Germany to ally with Austria, not Russia. Government Overview The Compromise turned the Habsburg domains into a real union between the Austrian Empire ("Lands Represented in the Imperial Council", or Cisleithania) in the western and northern half and the Kingdom of Hungary ("Lands of the Crown of Saint Stephen", or Transleithania) in the eastern half. The two halves shared a common monarch, who ruled as Emperor of Austria over the western and northern half portion and as King of Hungary over the eastern portion. Foreign relations and defense were managed jointly, and the two countries also formed a customs union. All other state functions were to be handled separately by each of the two states. Certain regions, such as Polish Galicia within Cisleithania and Croatia within Transleithania, enjoyed autonomous status, each with its own unique governmental structures (see: Polish Autonomy in Galicia and Croatian–Hungarian Settlement). The division between Austria and Hungary was so marked that there was no common citizenship: one was either an Austrian citizen or a Hungarian citizen, never both. This also meant that there were always separate Austrian and Hungarian passports, never a common one. However, neither Austrian nor Hungarian passports were used in the Kingdom of Croatia-Slavonia. Instead, the Kingdom issued its own passports, which were written in Croatian and French, and displayed the coat of arms of the Kingdom of Croatia-Slavonia-Dalmatia on them. Croatia-Slavonia also had executive autonomy regarding naturalization and citizenship, defined as "Hungarian-Croatian citizenship" for the kingdom's citizens. The Kingdom of Hungary had always maintained a separate parliament, the Diet of Hungary, even after the Austrian Empire was created in 1804. The administration and government of the Kingdom of Hungary (until 1848–49 Hungarian revolution) remained largely untouched by the government structure of the overarching Austrian Empire. Hungary's central government structures remained well separated from the Austrian imperial government. The country was governed by the Council of Lieutenancy of Hungary (the Gubernium) – located in Pressburg and later in Pest – and by the Hungarian Royal Court Chancellery in Vienna. The Hungarian government and Hungarian parliament were suspended after the Hungarian revolution of 1848 and were reinstated after the Austro-Hungarian Compromise in 1867. Vienna served as the Monarchy's primary capital. The Cisleithanian (Austrian) part contained about 57 percent of the total population and the larger share of its economic resources, compared to the Hungarian part. There were three parts to the rule of the Austro-Hungarian Empire: the common foreign, military, and a joint financial policy (only for diplomatic, military, and naval expenditures; later also included the Bosnian affairs) under the monarch the "Austrian" or Cisleithanian government (Lands Represented in the Imperial Council) the "Hungarian" or Transleithanian government (Lands of the Crown of Saint Stephen) The first prime minister of Hungary after the Compromise was Count Gyula Andrássy (1867–1871). The old Hungarian Constitution was restored, and Franz Joseph was crowned as King of Hungary. Andrássy next served as the Foreign Minister of Austria–Hungary (1871–1879). The Empire relied increasingly on a cosmopolitan bureaucracy—in which Czechs played an important role—backed by loyal elements, including a large part of the German, Hungarian, Polish and Croat aristocracy. After 1878, Bosnia and Herzegovina came under Austro-Hungarian military and civilian rule until it was fully annexed in 1908, provoking the Bosnian crisis among the other powers. The northern part of the Ottoman Sanjak of Novi Pazar was also under de facto joint occupation during that period, but the Austro-Hungarian army withdrew as part of their annexation of Bosnia. The annexation of Bosnia also led to Islam being recognized as an official state religion due to Bosnia's Muslim population. Joint government The common government (officially designated Ministerial Council for Common Affairs, or Ministerrat für gemeinsame Angelegenheiten in German) came into existence in 1867 as a result of the Austro-Hungarian Compromise. The Government of Austria, which ruled the monarchy until then became the government of the Austrian part and another government was formed for the Hungarian part. A common government was also formed for the few matters of common national security - the Common Army, navy, foreign policy and the imperial household, and the customs union. It consisted of three Imperial and Royal Joint-ministries (): Ministry of the Imperial and Royal Household and Foreign Affairs, known as the Imperial Chancellery before 1869; Imperial and Royal Ministry of War, known as the Imperial Ministry of War before 1911; Imperial and Royal Ministry of Finance, known as the Imperial Ministry of Finance before 1908, responsible only for the finances of the other two joint-ministries. The Minister of the Imperial and Royal Household and Foreign Affairs was the chairman (except when the Monarch was present and led the meetings himself) and thus he was de facto the common prime minister. Since 1869 the prime ministers of the Austrian and Hungarian halves of the monarchy were also members of the common government. Relations during the half-century after 1867 between the two parts of the dual monarchy featured repeated disputes over shared external tariff arrangements and over the financial contribution of each government to the common treasury. These matters were determined by the Austro-Hungarian Compromise of 1867, in which common expenditures were allocated 70% to Austria and 30% to Hungary. This division had to be renegotiated every ten years. There was political turmoil during the build-up to each renewal of the agreement. By 1907, the Hungarian share had risen to 36.4%. The disputes culminated in the early 1900s in a prolonged constitutional crisis. It was triggered by disagreement over which language to use for command in Hungarian army units and deepened by the advent to power in Budapest in April 1906 of a Hungarian nationalist coalition. Provisional renewals of the common arrangements occurred in October 1907 and in November 1917 on the basis of the status quo. The negotiations in 1917 ended with the dissolution of the Dual Monarchy. In 1878, the Congress of Berlin placed the Bosnia Vilayet of the Ottoman Empire under Austro-Hungarian occupation. The region was formally annexed in 1908 and was governed by Austria and Hungary jointly (a Condominium). The governor-general of Bosnia and Herzegovina was always an army officer, but he was first and foremost the head of the civil administration in the province (the Bosnian Office, ) and was subordinated to the common Ministry of Finance (as the common government lacked a ministry of the interior). Bosnia received a Territorial Statute (Landesstatut) with the setting up of a Territorial Diet, regulations for the election and procedure of the Diet, a law of associations, a law of public meetings, and a law dealing with the district councils. According to this statute Bosnia-Herzegovina formed a single administrative territory under the responsible direction and supervision of the Ministry of Finance of the Dual Monarchy in Vienna. Parliaments Hungary and Austria maintained separate parliaments, each with its own prime minister: the Diet of Hungary (commonly known as the National Assembly) and the Imperial Council () in Cisleithania. Each parliament had its own executive government, appointed by the monarch. Cisleithania The Imperial Council was a bicameral body: the upper house was the House of Lords (), and the lower house was the House of Deputies (). Members of the House of Deputies were elected through a system of "curiae" which weighted representation in favor of the wealthy but was progressively reformed until universal male suffrage was introduced in 1906. Transleithania The Diet of Hungary was also bicameral: the upper house was the House of Magnates (), and the lower house was the House of Representatives (). The "curia" system was also used to elect members of the House of Representatives. Franchise was very limited, with around 5% of men eligible to vote in 1874, rising to 8% at the beginning of World War I. Matters concerning Croatia-Slavonia alone fell to the Croatian-Slavonian Diet (commonly referred to as the Croatian Parliament). Bosnia and Herzegovina condominium The Diet (Sabor) of Bosnia-Herzegovina was created in 1910. Its setup consisted of a single Chamber, elected on the principle of the representation of interests. It numbered 92 members. The Diet had very limited legislative powers. The main legislative power was in the hands of the emperor, the parliaments in Vienna and Budapest, and the joint-minister of finance. The Diet of Bosnia could make proposals, but they had to be approved by both parliaments in Vienna and Budapest. The Diet could only deliberate on matters that affected Bosnia and Herzegovina exclusively; decisions on armed forces, commercial and traffic connections, customs, and similar matters, were made by the parliaments in Vienna and Budapest. The Diet also had no control over the National Council or the municipal councils. Government of Cisleithania The Emperor of the dual monarchy in his right of Emperor of Austria and King of Bohemia, ruler of the Austrian part of the realm, officially named The Kingdoms and Lands Represented in the Parliament of the Realm (Die im Reichsrate vertretenen Königreiche und Länder), simplified in 1915 to just Austrian Lands (Österreichische Länder) appointed the Government of Austria. The Austrian ministries carried the designation Imperial-Royal Ministry (sing. k.k. Ministerium), in which Imperial stands for the Kaiser's title of Emperor and Austria and Royal stands for his title of King of Bohemia. The central authorities were known as the "Ministry" (Ministerium). In 1867 the Ministerium consisted of seven ministries (Agriculture, Religion and Education, Finance, Interior, Justice, Commerce and Public Works, Defence). A Ministry of Railways was created in 1896, and the Ministry of Public Works was separated from Commerce in 1908. Ministries of and Social Welfare were established in 1917 to deal with issues arising from World War I. The ministries all had the title k.k. ("Imperial-Royal"), referring to the Imperial Crown of Austria and the Royal Crown of Bohemia. The administrative system in the Austrian Empire consisted of three levels: the central State administration, the territories (Länder), and the local communal administration. The State administration comprised all affairs having relation to rights, duties, and interests "which are common to all territories"; all other administrative tasks were left to the territories. Finally, the communes had self-government within their own sphere. Each of the seventeen territories of Cisleithania had an official from the central government, informally called a territorial chief (Landeschef). In five crown lands - the duchies of Salzburg, Carinthia, Carniola, Upper and Lower Silesia (commonly known as Austrian SIlesia) and Bukovina the territorial chief was called a Provincial President (Landespräsident) and his administrative office was called a Provincial Government (Landesregierung). The other twelve entities within the Austrian half of the Monarchy had an Imperial–royal Stateholder (K.k. Statthalter) with an administrative office called an Office of the Stateholder or Stateholder's Chancellery (Statthalterei). Each entity had its own provincial parliament, called a Landtag, elected by the voters (some princely nobles were unelected members in their own right). The Emperor appointed one of its members as Landeshauptmann (i.e., provincial premier). The Landeshauptmann was the Speaker of the Landtag and thus a member of the provincial legislature. Below the territory was the district (Bezirk) under a district-head (Bezirkshauptmann), appointed by the State government. These district-heads united nearly all the administrative functions which were divided among the various ministries. Each district was divided into a number of municipalities (Ortsgemeinden), each with its own elected mayor (Bürgermeister). The nine statutory cities were autonomous units at the district-level. The complexity of this system, particularly the overlap between State and territorial administration, led to moves for administrative reform. As early as 1904, premier Ernest von Koerber had declared that a complete change in the principles of administration would be essential if the machinery of State were to continue working. Richard von Bienerth's last act as Austrian premier in May 1911 was the appointment of a commission nominated by the Emperor to draw up a scheme of administrative reform. In March 1918, Seidler Government decided upon a program of national autonomy as a basis for administrative reform, which was, however, never carried into effect. Government of Transleithania The Emperor of the dual monarchy in his right of Apostolic King of Hungary and King of Croatia and Slavonia, ruler of the Hungarian part of the realm, officially named The Lands of the Holy Hungarian Crown (A Magyar Szent Korona országai) appointed the Government of Hungary. The Hungarian ministries carried the designation the Kingdom of Hungary's ... Ministry (sing. Magyar Királyi ...minisztérium), in which Royal stands for the Kaiser's title of Apostolic King of Hungary. From 1867 the administrative and political divisions of the lands belonging to the Hungarian crown were remodeled due to some restorations and other changes. In 1868 Transylvania was definitely reunited to Hungary proper, and the town and district of Fiume maintained its status as a Corpus separatum ("separate body"). The "Military Frontier" was abolished in stages between 1871 and 1881, with Banat and Šajkaška being incorporated into Hungary proper and the Croatian and Slavonian Military Frontiers joining Croatia-Slavonia. The Autonomous Government, officially Royal Croatian–Slavonian–Dalmatian Land Government ( or Kraljevska hrvatsko–slavonsko–dalmatinska zemaljska vlada) was established in 1869 with its seat in Zagreb. In regard to local government, Hungary had traditionally been divided into around seventy counties (, singular megye; Croatian: ) and an array of districts and cities with special statuses. This system was reformed in two stages. In 1870, most historical privileges of territorial subdivisions were abolished, but the existing names and territories were retained. At this point, there were a total of 175 territorial subdivisions: 65 counties (49 in Hungary proper, 8 in Transylvania, and 8 in Croatia), 89 cities with municipal rights, and 21 other types of municipality (3 in Hungary proper and 18 in Transylvania). In a further reform in 1876, most of the cities and other types of municipality were incorporated into the counties. The counties in Hungary were grouped into seven circuits, which had no administrative function. The lowest level subdivision was the district or processus (). After 1876, some urban municipalities remained independent of the counties in which they were situated. There were 26 of these urban municipalities in Hungary: Arad, Baja, Debreczen, Győr, Hódmezővásárhely, Kassa, Kecskemét, Kolozsvár, Komárom, Marosvásárhely, Nagyvárad, Pancsova, Pécs, Pozsony, Selmecz- és Bélabanya, Sopron, Szabadka, Szatmárnémeti, Szeged, Székesfehervár, Temesvár, Újvidék, Versecz, Zombor, and Budapest, the capital of the country. In Croatia-Slavonia, there were four: Osijek, Varaždin and Zagreb and Zemun. Fiume continued to form a separate division. The administration of the municipalities was carried on by an official appointed by the king. These municipalities each had a council of twenty members. Counties were led by a County head ( or ) appointed by the king and under the control of the Ministry of the Interior. Each county had a municipal committee of 20 members, comprising 50% virilists (persons paying the highest direct taxes) and 50% elected persons fulfilling the prescribed census and ex officio members (deputy county head, main notary, and others). The powers and responsibilities of the counties were constantly decreased and were transferred to regional agencies of the kingdom's ministries. Government of the Bosnia and Herzegovina condominium The Government of Bosnia and Herzegovina was headed by a governor-general (), who was both the head of the civil administration and the commander of the military forces based in Bosnia and Herzegovina. Due to the military functions of the position all nine governor-generals were army officers. The executive branch was headed by a National Council, which was chaired by the governor and contained the governor's deputy and chiefs of departments. At first, the government had only three departments, administrative, financial and legislative. Later, other departments, including construction, economics, education, religion, and technical, were founded as well. The administration of the country, together with the carrying out of the laws, devolved upon the Territorial Government in Sarajevo, which was subordinate and responsible to the Common Ministry of Finance. The existing administrative authorities of the Territory retained their previous organization and functions. The Austrian-Hungarian authorities left the Ottoman division of Bosnia and Herzegovina untouched, and only changed the names of divisional units. Thus the Bosnia Vilayet was renamed Reichsland, sanjaks were renamed Kreise (Circuits), kazas were renamed Bezirke (Districts), and nahiyahs became Exposituren. There were six Kreise and 54 Bezirke. The heads of the Kreises were Kreiseleiters, and the heads of the Bezirke were Bezirkesleiters. Judicial system Cisleithania The December Constitution of 1867 restored the rule of law, independence of the judiciary, and public jury trials in Austria. The system of general courts had the same four rungs it still has today: District courts (); Regional courts (); Higher regional courts (); Supreme Court (). Habsburg subjects would from now on be able to take the State to court should it violate their fundamental rights. Since regular courts were still unable to overrule the bureaucracy, much less the legislature, these guarantees necessitated the creation of specialist courts that could: The Administrative Court (), stipulated by the 1867 Basic Law on Judicial Power () and implemented in 1876, had the power to review the legality of administrative acts, ensuring that the executive branch remained faithful to the principle of the rule of law. The Imperial Court (), stipulated by the Basic Law on the Creation of an Imperial Court () in 1867 and implemented in 1869, decided demarcation conflicts between courts and the bureaucracy, between its constituent territories, and between individual territories and the Empire. The Imperial Court also heard complaints of citizens who claimed to have been violated in their constitutional rights, although its powers were not cassatory: it could only vindicate the complainant by the government to be in the wrong, not by actually voiding its wrongful decisions. The State Court () held the Emperor's ministers accountable for political misconduct committed in office. Although the Emperor could not be taken to court, many of his decrees now depended on the relevant minister to countersign them. The double-pronged approach of making the Emperor dependent on his ministers and also making ministers criminally liable for bad outcomes would firstly enable, secondly motivate the ministers to put pressure on the monarch. Transleithania Judicial power was also independent of the executive in Hungary. After the Croatian–Hungarian Settlement of 1868, Croatia-Slavonia had its own independent judicial system (the Table of Seven was the court of last instance for Croatia-Slavonia with final civil and criminal jurisdiction). The judicial authorities in Hungary were: the district courts with single judges (458 in 1905); the county courts with collegiate judgeships (76 in number); to these were attached 15 jury courts for press offences. These were courts of first instance. In Croatia-Slavonia these were known as the court tables after 1874; Royal Tables (12 in number), which were courts of second instance, established at Budapest, Debrecen, Győr, Kassa, Kolozsvár, Marosvásárhely, Nagyvárad, Pécs, Pressburg, Szeged, Temesvár and Ban's Table at Zagreb. The Royal Supreme Court at Budapest, and the Supreme Court of Justice, or Table of Seven, at Zagreb, which were the highest judicial authorities. There were also a special commercial court at Budapest, a naval court at Fiume, and special army courts. Bosnia and Herzegovina condominium The Territorial Statute introduced the modern rights and laws in Bosnia–Herzegovina, and it guaranteed generally the civil rights of the inhabitants of the Territory, namely citizenship, personal liberty, protection by the competent judicial authorities, liberty of creed and conscience, preservation of the national individuality and language, freedom of speech, freedom of learning and education, inviolability of the domicile, secrecy of posts and telegraphs, inviolability of property, the right of petition, and finally the right of holding meetings. The existing judicial authorities of the Territory retained their previous organization and functions. Budget Despite Austria and Hungary sharing a common currency, they were fiscally sovereign and independent entities. Since the beginnings of the personal union (from 1527), the government of the Kingdom of Hungary could preserve its separate and independent budget. After the revolution of 1848–1849, the Hungarian budget was amalgamated with the Austrian, and it was only after the Compromise of 1867 that Hungary obtained a separate budget. Voting rights Towards the end of the 19th century, the Austrian half of the dual monarchy began to move towards constitutionalism. A constitutional system with a parliament, the Reichsrat was created, and a bill of rights was enacted also in 1867. Suffrage to the Reichstag's lower house was gradually expanded until 1907, when equal suffrage for all male citizens was introduced. The 1907 Cisleithanian legislative election were the first elections held under universal male suffrage, after an electoral reform abolishing tax-paying requirements for voters had been adopted by the council and was endorsed by Emperor Franz Joseph earlier in the year. However, seat allocations were based on tax revenues from the States. Principal issues in the internal politics The traditional aristocracy and land-based gentry class gradually faced increasingly wealthy men of the cities, who achieved wealth through trade and industrialization. The urban middle and upper class tended to seek their own power and supported progressive movements in the aftermath of revolutions in Europe. As in the German Empire, the Austro-Hungarian Empire frequently used liberal economic policies and practices. From the 1860s, businessmen succeeded in industrializing parts of the Empire. Newly prosperous members of the bourgeoisie erected large homes and began to take prominent roles in urban life that rivaled the aristocracy's. In the early period, they encouraged the government to seek foreign investment to build up infrastructure, such as railroads, in aid of industrialization, transportation and communications, and development. The influence of liberals in Austria, most of them ethnic Germans, weakened under the leadership of Count Eduard von Taaffe, the Austrian prime minister from 1879 to 1893. Taaffe used a coalition of clergy, conservatives and Slavic parties to weaken the liberals. In Bohemia, for example, he authorized Czech as an official language of the bureaucracy and school system, thus breaking the German speakers' monopoly on holding office. Such reforms encouraged other ethnic groups to push for greater autonomy as well. By playing nationalities off one another, the government ensured the monarchy's central role in holding together competing interest groups in an era of rapid change. During the First World War, rising national sentiments and labour movements contributed to strikes, protests and civil unrest in the Empire. After the war, republican, national parties contributed to the disintegration and collapse of the monarchy in Austria and Hungary. Republics were established in Vienna and Budapest. Legislation to help the working class emerged from Catholic conservatives. They turned to social reform by using Swiss and German models and intervening in private industry. In Germany, Chancellor Otto von Bismarck had used such policies to neutralize socialist promises. The Catholics studied the Swiss Factory Act of 1877, which limited working hours for everyone and provided maternity benefits, and German laws that insured workers against industrial risks inherent in the workplace. These served as the basis for Austria's 1885 Trade Code Amendment. The Austro-Hungarian compromise and its supporters remained bitterly unpopular among the ethnic Hungarian voters, and the continuous electoral success of the pro-compromise Liberal Party frustrated many Hungarian voters. While the pro-compromise liberal parties were the most popular among ethnic minority voters, the Slovak, Serb, and Romanian minority parties remained unpopular among the ethnic minorities. The nationalist Hungarian parties, which were supported by the overwhelming majority of ethnic Hungarian voters, remained in the opposition, except from 1906 to 1910 where the nationalist Hungarian parties were able to form government. Foreign affairs The emperor officially had charge of foreign affairs. His minister of foreign affairs conducted diplomacy. See Ministers of the Imperial and Royal House and of Foreign Affairs of Austria-Hungary (1867–1918). Demographics The following data is based on the official Austro-Hungarian census conducted in 1910. Population and area Languages In Austria (Cisleithania), the census of 1910 recorded Umgangssprache, everyday language. Jews and those using German in offices often stated German as their Umgangssprache, even when having a different Muttersprache. 36.8% of the total population spoke German as their native language, and more than 71% of the inhabitants spoke some German. In Hungary (Transleithania), where the census was based primarily on mother tongue, 48.1% of the total population spoke Hungarian as their native language. Not counting autonomous Croatia-Slavonia, more than 54.4% of the inhabitants of the Kingdom of Hungary were native speakers of Hungarian (this included also the Jewsaround 5% of the populationas mostly they were Hungarian-speaking). Some languages were considered dialects of more widely spoken languages. For example: in the census, Rhaeto-Romance languages were counted as "Italian", while Istro-Romanian was counted as "Romanian". Yiddish was counted as "German" in both Austria and Hungary. Historical regions: Religion Solely in the Empire of Austria: Solely in the Kingdom of Hungary: Largest cities Data: census in 1910 Ethnic relations In July 1849, the Hungarian Revolutionary Parliament proclaimed and enacted ethnic and minority rights (the next such laws were in Switzerland), but these were overturned after the Russian and Austrian armies crushed the Hungarian Revolution. After the Kingdom of Hungary reached the Compromise with the Habsburg Dynasty in 1867, one of the first acts of its restored Parliament was to pass a Law on Nationalities (Act Number XLIV of 1868). It was a liberal piece of legislation and offered extensive language and cultural rights. It did not recognize non-Hungarians to have rights to form states with any territorial autonomy. The "Austro-Hungarian Compromise of 1867" created the personal union of the independent states of Hungary and Austria, linked under a common monarch also having joint institutions. The Hungarian majority asserted more of their identity within the Kingdom of Hungary, and it came to conflict with some of her own minorities. The imperial power of German-speakers who controlled the Austrian half was resented by others. In addition, the emergence of nationalism in the newly independent Romania and Serbia also contributed to ethnic issues in the empire. Article 19 of the 1867 "Basic State Act" (Staatsgrundgesetz), valid only for the Cisleithanian (Austrian) part of Austria–Hungary, said: The implementation of this principle led to several disputes, as it was not clear which languages could be regarded as "customary". The Germans, the traditional bureaucratic, capitalist and cultural elite, demanded the recognition of their language as a customary language in every part of the empire. German nationalists, especially in the Sudetenland (part of Bohemia), looked to Berlin in the new German Empire. There was a German-speaking element in Austria proper (west of Vienna), but it did not display much sense of German nationalism. That is, it did not demand an independent state; rather it flourished by holding most of the high military and diplomatic offices in the Empire. Italian was regarded as an old "culture language" () by German intellectuals and had always been granted equal rights as an official language of the Empire, but the Germans had difficulty in accepting the Slavic languages as equal to their own. On one occasion Count A. Auersperg (Anastasius Grün) entered the Diet of Carniola carrying what he claimed to be the whole corpus of Slovene literature under his arm; this was to demonstrate that the Slovene language could not be substituted for German as the language of higher education. The following years saw official recognition of several languages, at least in Austria. From 1867, laws awarded Croatian equal status with Italian in Dalmatia. From 1882, there was a Slovene majority in the Diet of Carniola and in the capital Laibach (Ljubljana); they replaced German with Slovene as their primary official language. Galicia designated Polish instead of German in 1869 as the customary language of government. Istro-Romanians In Istria, the Istro-Romanians, a small ethnic group composed by around 2,600 people in the 1880s, suffered severe discrimination. The Croats of the region, who formed the majority, tried to assimilate them, while the Italian minority supported them in their requests for self-determination. In 1888, the possibility of opening the first school for the Istro-Romanians teaching in the Romanian language was discussed in the Diet of Istria. The proposal was very popular among them. The Italian deputies showed their support, but the Croat ones opposed it and tried to show that the Istro-Romanians were in fact Slavs. During Austro-Hungarian rule, the Istro-Romanians lived under poverty conditions, and those living in the island of Krk were fully assimilated by 1875. Bohemia The language disputes were most fiercely fought in Bohemia, where the Czech speakers formed a majority and sought equal status for their language to German. The Czechs had lived primarily in Bohemia since the 6th century and German immigrants had begun settling the Bohemian periphery in the 13th century. The constitution of 1627 made the German language a second official language and equal to Czech. German speakers lost their majority in the Bohemian Diet in 1880 and became a minority to Czech speakers in the cities of Prague and Pilsen (while retaining a slight numerical majority in the city of Brno (Brünn)). The old Charles University in Prague, hitherto dominated by German speakers, was divided into German and Czech-speaking faculties in 1882. Hungarian Dominance At the same time, Hungarian dominance faced challenges from the local majorities of Romanians in Transylvania and in the eastern Banat, Slovaks in today's Slovakia, and Croats and Serbs in the crown lands of Croatia and of Dalmatia (today's Croatia), in Bosnia and Herzegovina and in the provinces known as the Vojvodina (today's northern Serbia). The Romanians and the Serbs began to agitate for union with their fellow nationalists and language speakers in the newly founded states of Romania (1859–1878) and Serbia. Trialist Proclamation Hungary's leaders were generally less willing than their Austrian counterparts to share power with their subject minorities, but they granted a large measure of autonomy to Croatia in 1868. To some extent, they modeled their relationship to that kingdom on their own compromise with Austria of the previous year. In spite of nominal autonomy, the Croatian government was an economic and administrative part of Hungary, which the Croatians resented. In the Kingdom of Croatia-Slavonia and Bosnia and Herzegovina many advocated the idea of a trialist Austro-Hungaro-Croatian monarchy; among the supporters of the idea were Archduke Leopold Salvator, Archduke Franz Ferdinand and emperor and king Charles I who during his short reign supported the trialist idea only to be vetoed by the Hungarian government and Count Istvan Tisza. The count finally signed the trialist proclamation after heavy pressure from the king on 23 October 1918. Language Language was one of the most contentious issues in Austro-Hungarian politics. All governments faced difficult and divisive hurdles in deciding on the languages of government and of instruction. The minorities sought the widest opportunities for education in their own languages, as well as in the "dominant" languages—Hungarian and German. By the "Ordinance of 5 April 1897", the Austrian Prime Minister Count Kasimir Felix Badeni gave Czech equal standing with German in the internal government of Bohemia; this led to a crisis because of nationalist German agitation throughout the empire. The Crown dismissed Badeni. The Hungarian Minority Act of 1868 gave the minorities (Slovaks, Romanians, Serbs, et al.) individual (but not also communal) rights to use their language in offices, schools (although in practice often only in those founded by them and not by the state), courts and municipalities (if 20% of the deputies demanded it). Beginning with the 1879 Primary Education Act and the 1883 Secondary Education Act, the Hungarian state made more efforts to reduce the use of non-Magyar languages, in strong violation of the 1868 Nationalities Law. After 1875, all Slovak language schools higher than elementary were closed, including the only three high schools (gymnasiums) in Revúca (Nagyrőce), Turčiansky Svätý Martin (Turócszentmárton) and Kláštor pod Znievom (Znióváralja). From June 1907, all public and private schools in Hungary were obliged to ensure that after the fourth grade, the pupils could express themselves fluently in Hungarian. This led to the further closing of minority schools, devoted mostly to the Slovak and Rusyn languages. The two kingdoms sometimes divided their spheres of influence. According to Misha Glenny in his book, The Balkans, 1804–1999, the Austrians responded to Hungarian support of Czechs by supporting the Croatian national movement in Zagreb. In recognition that he reigned in a multi-ethnic country, Emperor Franz Joseph spoke (and used) German, Hungarian and Czech fluently, and Croatian, Serbian, Polish and Italian to some degree. Jews Around 1900, Jews numbered about two million in the whole territory of the Austro-Hungarian Empire; their position was ambiguous. The populist and antisemitic politics of the Christian Social Party are sometimes viewed as a model for Adolf Hitler's Nazism. Antisemitic parties and movements existed, but the governments of Vienna and Budapest did not initiate pogroms or implement official antisemitic policies. They feared that such ethnic violence could ignite other ethnic minorities and escalate out of control. The antisemitic parties remained on the periphery of the political sphere due to their low popularity among voters in the parliamentary elections. In that period, the majority of Jews in Austria–Hungary lived in small towns (shtetls) in Galicia and rural areas in Hungary and Bohemia; however, they had large communities and even local majorities in the downtown districts of Vienna, Budapest, Prague, Kraków and Lwów. Of the pre-World War I military forces of the major European powers, the Austro-Hungarian army was almost alone in its regular promotion of Jews to positions of command. While the Jewish population of the lands of the Dual Monarchy was about 5%, Jews made up nearly 18% of the reserve officer corps. Thanks to the modernity of the constitution and to the benevolence of emperor Franz Joseph, the Austrian Jews came to regard the era of Austria–Hungary as a golden era of their history. By 1910 about 900,000 religious Jews made up approximately 5% of the population of Hungary and about 23% of Budapest's citizenry. Jews accounted for 54% of commercial business owners, 85% of financial institution directors and owners in banking, and 62% of all employees in commerce, 20% of all general grammar school students, and 37% of all commercial scientific grammar school students, 31.9% of all engineering students, and 34.1% of all students in human faculties of the universities. Jews were accounted for 48.5% of all physicians, and 49.4% of all lawyers/jurists in Hungary. Note: The numbers of Jews were reconstructed from religious censuses. They did not include the people of Jewish origin who had converted to Christianity, or the number of atheists. Among many Hungarian parliament members of Jewish origin, the most famous Jewish members in Hungarian political life were Vilmos Vázsonyi as Minister of Justice, Samu Hazai as Minister of War, János Teleszky as minister of finance, János Harkányi as minister of trade, and József Szterényi as minister of trade. Education Universities in Cisleithania The first university in the Austrian half of the Empire (Charles University) was founded by H.R. Emperor Charles IV in Prague in 1347, the second oldest university was the Jagiellonian University established in Kraków by the King of Poland Casimir III the Great in 1364, while the third oldest (University of Vienna) was founded by Duke Rudolph IV in 1365. The higher educational institutions were predominantly German, but beginning in the 1870s, language shifts began to occur. These establishments, which in the middle of the 19th century had had a predominantly German character, underwent in Galicia a conversion into Polish national institutions, in Bohemia and Moravia a separation into German and Czech ones. Thus Germans, Czechs and Poles were provided for. But now the smaller nations also made their voices heard: the Ruthenians, Slovenes and Italians. The Ruthenians demanded at first, in view of the predominantly Ruthenian character of rural East Galicia, a national partition of the Polish University of Lwów. Since the Poles were at first unyielding, Ruthenian demonstrations and strikes of students arose, and the Ruthenians were no longer content with the reversion of a few separate professorial chairs, and with parallel courses of lectures. By a pact concluded on 28 January 1914 the Poles promised a Ruthenian university; but owing to the war the question lapsed. The Italians could hardly claim a university of their own on grounds of population (in 1910 they numbered 783,000), but they claimed it all the more on grounds of their ancient culture. All parties were agreed that an Italian faculty of laws should be created; the difficulty lay in the choice of the place. The Italians demanded Trieste; but the Government was afraid to let this Adriatic port become the centre of an irredenta; moreover the Southern Slavs of the city wished it kept free from an Italian educational establishment. Bienerth in 1910 brought about a compromise; namely, that it should be founded at once, the situation to be provisionally in Vienna, and to be transferred within four years to Italian national territory. The German National Union (Nationalverband) agreed to extend temporary hospitality to the Italian university in Vienna, but the Southern Slav Hochschule Club demanded a guarantee that a later transfer to the coast provinces should not be contemplated, together with the simultaneous foundation of Slovene professorial chairs in Prague and Cracow, and preliminary steps towards the foundation of a Southern Slav university in Laibach. But in spite of the constant renewal of negotiations for a compromise it was impossible to arrive at any agreement, until the outbreak of war left all the projects for a Ruthenian university at Lemberg, a Slovene one in Laibach, and a second Czech one in Moravia, unrealized. Universities in Transleithania In the year 1276, the university of Veszprém was destroyed by the troops of Péter Csák and it was never rebuilt. A university was established by Louis I of Hungary in Pécs in 1367. Sigismund established a university at Óbuda in 1395. Another, Universitas Istropolitana, was established 1465 in Pozsony (now Bratislava in Slovakia) by Mattias Corvinus. None of these medieval universities survived the Ottoman wars. Nagyszombat University was founded in 1635 and moved to Buda in 1777 and it is called Eötvös Loránd University today. The world's first institute of technology was founded in Selmecbánya, Kingdom of Hungary (since 1920 Banská Štiavnica, now Slovakia) in 1735. Its legal successor is the University of Miskolc in Hungary. The Budapest University of Technology and Economics (BME) is considered the oldest institute of technology in the world with university rank and structure. Its legal predecessor the Institutum Geometrico-Hydrotechnicum was founded in 1782 by Emperor Joseph II. The high schools included the universities, of which Hungary possessed five, all maintained by the state: at Budapest (founded in 1635), at Kolozsvár (founded in 1872), and at Zagreb (founded in 1874). Newer universities were established in Debrecen in 1912, and Pozsony university was reestablished after a half millennium in 1912. They had four faculties: theology, law, philosophy and medicine (the university at Zagreb was without a faculty of medicine). There were in addition ten high schools of law, called academies, which in 1900 were attended by 1,569 pupils. The Polytechnicum in Budapest, founded in 1844, which contained four faculties and was attended in 1900 by 1,772 pupils, was also considered a high school. There were in Hungary in 1900 forty-nine theological colleges, twenty-nine Catholic, five Greek Uniat, four Greek Orthodox, ten Protestant and one Jewish. Among special schools the principal mining schools were at Selmeczbánya, Nagyág and Felsőbánya; the principal agricultural colleges at Debreczen and Kolozsvár; and there was a school of forestry at Selmeczbánya, military colleges at Budapest, Kassa, Déva and Zagreb, and a naval school at Fiume. There were in addition a number of training institutes for teachers and a large number of schools of commerce, several art schools – for design, painting, sculpture, music Economy Overview The heavily rural Austro-Hungarian economy slowly modernised after 1867. Railroads opened up once-remote areas, and cities grew. Many small firms promoted capitalist way of production. Technological change accelerated industrialization and urbanization. The first Austrian stock exchange (the Wiener Börse) was opened in 1771 in Vienna, the first stock exchange of the Kingdom of Hungary (the Budapest Stock Exchange) was opened in Budapest in 1864. The central bank (Bank of issue) was founded as Austrian National Bank in 1816. In 1878, it transformed into Austro-Hungarian National Bank with principal offices in both Vienna and Budapest. The central bank was governed by alternating Austrian or Hungarian governors and vice-governors. The gross national product per capita grew roughly 1.76% per year from 1870 to 1913. That level of growth compared very favorably to that of other European nations such as Britain (1%), France (1.06%), and Germany (1.51%). However, in a comparison with Germany and Britain, the Austro-Hungarian economy as a whole still lagged considerably, as sustained modernization had begun much later. Like the German Empire, that of Austria–Hungary frequently employed liberal economic policies and practices. In 1873, the old Hungarian capital Buda and Óbuda (Ancient Buda) were officially merged with the third city, Pest, thus creating the new metropolis of Budapest. The dynamic Pest grew into Hungary's administrative, political, economic, trade and cultural hub. Many of the state institutions and the modern administrative system of Hungary were established during this period. Economic growth centered on Vienna and Budapest, the Austrian lands (areas of modern Austria), the Alpine region and the Bohemian lands. In the later years of the 19th century, rapid economic growth spread to the central Hungarian plain and to the Carpathian lands. As a result, wide disparities of development existed within the empire. In general, the western areas became more developed than the eastern ones. The Kingdom of Hungary became the world's second-largest flour exporter after the United States. The large Hungarian food exports were not limited to neighbouring Germany and Italy: Hungary became the most important foreign food supplier of the large cities and industrial centres of the United Kingdom. Galicia, which has been described as the poorest province of Austro-Hungary, experienced near-constant famines, resulting in 50,000 deaths a year. The Istro-Romanians of Istria were also poor, as pastoralism lost strength and agriculture was not productive. However, by the end of the 19th century, economic differences gradually began to even out as economic growth in the eastern parts of the monarchy consistently surpassed that in the western. The strong agriculture and food industry of the Kingdom of Hungary with the centre of Budapest became predominant within the empire and made up a large proportion of the export to the rest of Europe. Meanwhile, western areas, concentrated mainly around Prague and Vienna, excelled in various manufacturing industries. This division of labour between the east and west, besides the existing economic and monetary union, led to an even more rapid economic growth throughout Austria–Hungary by the early 20th century. However, since the turn of the twentieth century, the Austrian half of the Monarchy could preserve its dominance within the empire in the sectors of the first industrial revolution, but Hungary had a better position in the industries of the second industrial revolution, in these modern sectors of the second industrial revolution the Austrian competition could not become dominant. Trade From 1527 (the creation of the monarchic personal union) to 1851, the Kingdom of Hungary maintained its own customs controls, which separated it from the other parts of the Habsburg-ruled territories. After 1867, the Austrian and Hungarian customs union agreement had to be renegotiated and stipulated every ten years. The agreements were renewed and signed by Vienna and Budapest at the end of every decade because both countries hoped to derive mutual economic benefit from the customs union. The Austrian Empire and the Kingdom of Hungary contracted their foreign commercial treaties independently of each other. Industry The empire's heavy industry had mostly focused on machine building, especially for the electric power industry, locomotive industry and automotive industry, while in light industry the precision mechanics industry was the most dominant. Through the years leading up to World War I the country became the 4th biggest machine manufacturer in the world. The two most important trading partners were traditionally Germany (1910: 48% of all exports, 39% of all imports), and Great Britain (1910: almost 10% of all exports, 8% of all imports), the third most important partner was the United States, it followed by Russia, France, Switzerland, Romania, the Balkan states and South America. Trade with the geographically neighbouring Russia, however, had a relatively low weight (1910: 3% of all exports /mainly machinery for Russia, 7% of all imports /mainly raw materials from Russia). Automotive industry Prior to World War I, the Austrian Empire had five car manufacturer companies. These were: Austro-Daimler in Wiener-Neustadt (cars trucks, buses), Gräf & Stift in Vienna (cars), Laurin & Klement in Mladá Boleslav (motorcycles, cars), Nesselsdorfer in Nesselsdorf (Kopřivnice), Moravia (automobiles), and Lohner-Werke in Vienna (cars). Austrian car production started in 1897. Prior to World War I, the Kingdom of Hungary had four car manufacturer companies. These were: the Ganz company in Budapest, RÁBA Automobile in Győr, MÁG (later Magomobil) in Budapest, and MARTA (Hungarian Automobile Joint-stock Company Arad) in Arad. Hungarian car production started in 1900. Automotive factories in the Kingdom of Hungary manufactured motorcycles, cars, taxicabs, trucks and buses. Electrical industry and electronics In 1884, Károly Zipernowsky, Ottó Bláthy and Miksa Déri (ZBD), three engineers associated with the Ganz Works of Budapest, determined that open-core devices were impractical, as they were incapable of reliably regulating voltage. When employed in parallel connected electric distribution systems, closed-core transformers finally made it technically and economically feasible to provide electric power for lighting in homes, businesses and public spaces. The other essential milestone was the introduction of 'voltage source, voltage intensive' (VSVI) systems' by the invention of constant voltage generators in 1885. Bláthy had suggested the use of closed cores, Zipernowsky had suggested the use of parallel shunt connections, and Déri had performed the experiments; The first Hungarian water turbine was designed by the engineers of the Ganz Works in 1866, the mass production with dynamo generators started in 1883. The manufacturing of steam turbo generators started in the Ganz Works in 1903. In 1905, the Láng Machine Factory company also started the production of steam turbines for alternators. Tungsram is a Hungarian manufacturer of light bulbs and vacuum tubes since 1896. On 13 December 1904, Hungarian Sándor Just and Croatian Franjo Hanaman were granted a Hungarian patent (No. 34541) for the world's first tungsten filament lamp. The tungsten filament lasted longer and gave brighter light than the traditional carbon filament. Tungsten filament lamps were first marketed by the Hungarian company Tungsram in 1904. This type is often called Tungsram-bulbs in many European countries. Despite the long experimentation with vacuum tubes at Tungsram company, the mass production of radio tubes begun during WW1, and the production of X-ray tubes started also during the WW1 in Tungsram Company. The Orion Electronics was founded in 1913. Its main profiles were the production of electrical switches, sockets, wires, incandescent lamps, electric fans, electric kettles, and various household electronics. The telephone exchange was an idea of the Hungarian engineer Tivadar Puskás (1844–1893) in 1876, while he was working for Thomas Edison on a telegraph exchange. The first Hungarian telephone factory (Factory for Telephone Apparatuses) was founded by János Neuhold in Budapest in 1879, which produced telephones microphones, telegraphs, and telephone exchanges. In 1884, the Tungsram company also started to produce microphones, telephone apparatuses, telephone switchboards and cables. The Ericsson company also established a factory for telephones and switchboards in Budapest in 1911. Aeronautic industry The first airplane in Austria was Edvard Rusjan's design, the Eda I, which had its maiden flight in the vicinity of Gorizia on 25 November 1909. The first Hungarian hydrogen-filled experimental balloons were built by István Szabik and József Domin in 1784. The first Hungarian designed and produced airplane (powered by a Hungarian built inline engine) was flown at Rákosmező on 4 November 1909. The earliest Hungarian airplane with Hungarian built radial engine was flown in 1913. Between 1912 and 1918, the Hungarian aircraft industry began developing. The three greatest: UFAG Hungarian Aircraft Factory (1914), Hungarian General Aircraft Factory (1916), Hungarian Lloyd Aircraft, Engine Factory at Aszód (1916), and Marta in Arad (1914). During the First World War, fighter planes, bombers and reconnaissance planes were produced in these factories. The most important aero-engine factories were Weiss Manfred Works, GANZ Works, and Hungarian Automobile Joint-stock Company Arad. Rolling stock manufacturers The factories producing rolling stock such as locomotives, steam engines and wagons, but also bridges and other iron structures, were installed in Vienna (Locomotive Factory of the State Railway Company, founded in 1839), in Wiener Neustadt (New Vienna Locomotive Factory, founded in 1841), and in Floridsdorf (Floridsdorf Locomotive Factory, founded in 1869). The Hungarian factories producing rolling stock as well as bridges and other iron structures were the MÁVAG company in Budapest (steam engines and wagons) and the Ganz company in Budapest (steam engines, wagons, the production of electric locomotives and electric trams started from 1894). and the RÁBA Company in Győr. Shipbuilding The largest shipyard in the dual monarchy and a strategic asset for the Austro-Hungarian Navy was the Stabilimento Tecnico Triestino in Trieste, founded in 1857 by Wilhelm Strudthoff. Second in importance was the Danubius Werft in Fiume (present-day Rijeka, Croatia). Third in importance for the naval shipbuilding was the Navy's own Marinearsenal, located at the main naval base in Pola, present-day Croatia. Smaller shipyards included the Cantiere Navale Triestino in Monfalcone (established in 1908 with ship repairs as the main activity, but went on during the war to manufacture submarines) and the in Fiume. The latter was established in 1854 under the name Stabilimento Tecnico Fiume with Robert Whitehead as the enterprise's director and the purpose to produce his torpedoes for the Navy. The company went bankrupt in 1874 and in the following year Whitehead bought it to establish the Whitehead & Co. Next to torpedoes the company went on to produce submarines during WWI. On the Danube, the DDSG had established the Óbuda Shipyard on the Hungarian Hajógyári Island in 1835. The largest Hungarian shipbuilding company was the Ganz-Danubius. Infrastructure Telecommunications Telegraph The first telegraph connection (Vienna—Brno—Prague) had started operation in 1847. In Hungarian territory the first telegraph stations were opened in Pressburg (Pozsony, today's Bratislava) in December 1847 and in Buda in 1848. The first telegraph connection between Vienna and Pest–Buda (later Budapest) was constructed in 1850, and Vienna–Zagreb in 1850. Austria subsequently joined a telegraph union with German states. In the Kingdom of Hungary, 2,406 telegraph post offices operated in 1884. By 1914 the number of telegraph offices reached 3,000 in post offices and further 2,400 were installed in the railway stations of the Kingdom of Hungary. Telephone The first telephone exchange was opened in Zagreb (8 January 1881), the second was in Budapest (1 May 1881), and the third was opened in Vienna (3 June 1881). Initially telephony was available in the homes of individual subscribers, companies and offices. Public telephone stations appeared in the 1890s, and they quickly became widespread in post offices and railway stations. Austria–Hungary had 568 million telephone calls in 1913; only two Western European countries had more phone calls: the German Empire and the United Kingdom. The Austro-Hungarian Empire was followed by France with 396 million telephone calls and Italy with 230 million phone calls. In 1916, there were 366 million telephone calls in Cisleithania, among them 8.4 million long distant calls. All telephone exchanges of the cities, towns and larger villages in Transleithania were linked until 1893. By 1914, more than 2000 settlements had telephone exchange in Kingdom of Hungary. Electronic audio broadcasting The Telefon Hírmondó (Telephone Herald) news and entertainment service was introduced in Budapest in 1893. Two decades before the introduction of radio broadcasting, people could listen to political, economic and sports news, cabaret, music and opera in Budapest daily. It operated over a special type of telephone exchange system. Rail transport By 1913, the combined length of the railway tracks of the Austrian Empire and Kingdom of Hungary reached . In Western Europe only Germany had more extended railway network (); the Austro-Hungarian Empire was followed by France (), the United Kingdom (), Italy () and Spain (). Railways in Cisleithania Rail transport expanded rapidly in the Austro-Hungarian Empire. Its predecessor state, the Habsburg Empire, had built a substantial core of railways in the west, originating from Vienna, by 1841. Austria's first steam railway from Vienna to Moravia with its terminus in Galicia (Bochnie) was opened in 1839. The first train travelled from Vienna to Lundenburg (Břeclav) on 6 June 1839 and one month later between the imperial capital in Vienna and the capital of Moravia Brünn (Brno) on 7 July. At that point, the government realized the military possibilities of rail and began to invest heavily in construction. Pozsony (Bratislava), Budapest, Prague, Kraków, Lviv, Graz, Laibach (Ljubljana) and Venedig (Venice) became linked to the main network. By 1854, the empire had almost of track, about 60–70% of it in state hands. The government then began to sell off large portions of track to private investors to recoup some of its investments and because of the financial strains of the 1848 Revolution and of the Crimean War. From 1854 to 1879, private interests conducted almost all rail construction. What would become Cisleithania gained of track, and Hungary built of track. During this time, many new areas joined the railway system and the existing rail networks gained connections and interconnections. This period marked the beginning of widespread rail transportation in Austria–Hungary, and also the integration of transportation systems in the area. Railways allowed the empire to integrate its economy far more than previously possible, when transportation depended on rivers. After 1879, the Austrian and the Hungarian governments slowly began to renationalize their rail networks, largely because of the sluggish pace of development during the worldwide depression of the 1870s. Between 1879 and 1900, more than of railways were built in Cisleithania and Hungary. Most of this constituted "filling in" of the existing network, although some areas, primarily in the far east, gained rail connections for the first time. The railway reduced transportation costs throughout the empire, opening new markets for products from other lands of the Dual Monarchy. In 1914, of a total of of railway tracks in Austria, (82%) were state-owned. Railways in Transleithania The first Hungarian steam locomotive railway line was opened on 15 July 1846 between Pest and Vác. In 1890 most large Hungarian private railway companies were nationalized as a consequence of the poor management of private companies, except the strong Austrian-owned Kaschau-Oderberg Railway (KsOd) and the Austrian-Hungarian Southern Railway (SB/DV). They also joined the zone tariff system of the MÁV (Hungarian State Railways). By 1910, the total length of the rail networks of Hungarian Kingdom reached , the Hungarian network linked more than 1,490 settlements. Nearly half (52%) of the empire's railways were built in Hungary, thus the railroad density there became higher than that of Cisleithania. This has ranked Hungarian railways the 6th most dense in the world (ahead of Germany and France). Electrified commuter railways: A set of four electric commuter rai lines were built in Budapest, the BHÉV: Ráckeve line (1887), Szentendre line (1888), Gödöllő line (1888), Csepel line (1912) Tramway lines in the cities Horse-drawn tramways appeared in the first half of the 19th century. Between the 1850s and 1880s many were built : Vienna (1865), Budapest (1866), Brno (1869), Trieste (1876). Steam trams appeared in the late 1860s. The electrification of tramways started in the late 1880s. The first electrified tramway in Austria–Hungary was built in Budapest in 1887.

Underground The Budapest Metro Line 1 (originally the "Franz Joseph Underground Electric Railway Company") is the second oldest underground railway in the world (the first being the London Underground's Metropolitan Line and the third being Glasgow), and the first on the European mainland. It was built from 1894 to 1896 and opened on 2 May 1896. In 2002, it was listed as a UNESCO World Heritage Site. The M1 line became an IEEE Milestone due to the radically new innovations in its era: "Among the railway's innovative elements were bidirectional tram cars; electric lighting in the subway stations and tram cars; and an overhead wire structure instead of a third-rail system for power". Inland waterways and river regulation In 1900 the engineer C. Wagenführer drew up plans to link the Danube and the Adriatic Sea by a canal from Vienna to Trieste. It was born from the desire of Austria–Hungary to have a direct link to the Adriatic Sea but was never constructed. Lower Danube and the Iron Gates In 1831 a plan had already been drafted to make the passage navigable, at the initiative of the Hungarian politician István Széchenyi. Finally Gábor Baross, Hungary's "Iron Minister", succeeded in financing this project. The riverbed rocks and the associated rapids made the gorge valley an infamous passage for shipping. In German, the passage is still known as the Kataraktenstrecke, even though the cataracts are gone. Near the actual "Iron Gates" strait the Prigrada rock was the most important obstacle until 1896: the river widened considerably here and the water level was consequently low. Upstream, the Greben rock near the "Kazan" gorge was notorious. Tisza River The length of the Tisza in Hungary used to be . It flowed through the Great Hungarian Plain, which is one of the largest flat areas in central Europe. Since plains can cause a river to flow very slowly, the Tisza used to follow a path with many curves and turns, which led to many large floods in the area. After several small-scale attempts, István Széchenyi organised the "regulation of the Tisza" (Hungarian: a Tisza szabályozása) which started on 27 August 1846, and substantially ended in 1880. The new length of the river in Hungary was ( total), with of "dead channels" and of new riverbed. The resultant length of the flood-protected river comprises (out of of all Hungarian protected rivers). Shipping and ports The most important seaport was Trieste (today part of Italy), where the Austrian merchant marine was based. Two major shipping companies (Austrian Lloyd and Austro-Americana) and several shipyards were located there. From 1815 to 1866, Venice had been part of the Habsburg empire. The loss of Venice prompted the development of the Austrian merchant marine. By 1913, the commercial marine of Austria, comprised 16,764 vessels with a tonnage of 471,252, and crews number-ing 45,567. Of the total (1913) 394 of 422,368 tons were steamers, and 16,370 of 48,884 tons were sailing vessels The Austrian Lloyd was one of the biggest ocean shipping companies of the time. Prior to the beginning of World War I, the company owned 65 middle-sized and large steamers. The Austro-Americana owned one third of this number, including the biggest Austrian passenger ship, the SS Kaiser Franz Joseph I. In comparison to the Austrian Lloyd, the Austro-American concentrated on destinations in North and South America. The Austro-Hungarian Navy became much more significant than previously, as industrialization provided sufficient revenues to develop it. Pola (Pula, today part of Croatia) was especially significant for the navy. The most important seaport for the Hungarian part of the monarchy was Fiume (Rijeka, today part of Croatia), where the Hungarian shipping companies, such as the Adria, operated. The commercial marine of the Kingdom of Hungary in 1913 comprised 545 vessels of 144,433 tons, and crews numbering 3,217. Of the total number of vessels 134,000 of 142,539 tons were steamers, and 411 of 1,894 tons were sailing vessels. The first Danubian steamer company, Donaudampfschiffahrtsgesellschaft (DDSG), was the largest inland shipping company in the world until the collapse of Austria-Hungary. Military The Austro-Hungarian Army was under the command of Archduke Albrecht, Duke of Teschen (1817–1895), an old-fashioned bureaucrat who opposed modernization. The military system of the Austro-Hungarian monarchy was similar in both states, and rested since 1868 upon the principle of the universal and personal obligation of the citizen to bear arms. Its military force was composed of the common army; the special armies, namely the Austrian Landwehr, and the Hungarian Honved, which were separate national institutions, and the Landsturm or levy-en masse. As stated above, the common army stood under the administration of the joint minister of war, while the special armies were under the administration of the respective ministries of national defence. The yearly contingent of recruits for the army was fixed by the military bills voted on by the Austrian and Hungarian parliaments and was generally determined on the basis of the population, according to the last census returns. It amounted in 1905 to 103,100 men, of which Austria furnished 59,211 men, and Hungary 43,889. Besides 10,000 men were annually allotted to the Austrian Landwehr, and 12,500 to the Hungarian Honved. The term of service was two years (three years in the cavalry) with the colours, seven or eight in the reserve and two in the Landwehr; in the case of men not drafted to the active army the same total period of service was spent in various special reserves. The common minister of war was the head for the administration of all military affairs, except those of the Austrian Landwehr and of the Hungarian Honved, which were committed to the ministries for national defence of the two respective states. But the supreme command of the army was nominally vested in the monarch, who had the power to take all measures regarding the whole army. In practice, the emperor's nephew Archduke Albrecht was his chief military advisor and made the policy decisions. The Austro-Hungarian Navy was mainly a coast defence force, and also included a flotilla of monitors for the Danube. It was administered by the naval department of the ministry of war. 1914–1918: World War I 1878–1914: Congress of Berlin, Balkan instability and the Bosnia Crisis Russian Pan-Slavic organizations sent aid to the Balkan rebels and so pressured the tsar's government to declare war on the Ottoman Empire in 1877 in the name of protecting Orthodox Christians. Unable to mediate between the Ottoman Empire and Russia over the control of Serbia, Austria–Hungary declared neutrality when the conflict between the two powers escalated into a war. With help from Romania and Greece, Russia defeated the Ottomans and with the Treaty of San Stefano tried to create a large pro-Russian Bulgaria. This treaty sparked an international uproar that almost resulted in a general European war. Austria–Hungary and Britain feared that a large Bulgaria would become a Russian satellite that would enable the tsar to dominate the Balkans. British prime minister Benjamin Disraeli moved warships into position against Russia to halt the advance of Russian influence in the eastern Mediterranean so close to Britain's route through the Suez Canal. The Treaty of San Stefano was seen in Austria as much too favourable for Russia and its Orthodox-Slavic goals. The Congress of Berlin rolled back the Russian victory by partitioning the large Bulgarian state that Russia had carved out of Ottoman territory and denying any part of Bulgaria full independence from the Ottomans. The Congress of Berlin in 1878 let Austria occupy (but not annex) the province of Bosnia and Herzegovina, a predominantly Slavic area. Austria occupied Bosnia and Herzegovina as a way of gaining power in the Balkans. Serbia, Montenegro and Romania became fully independent. Nonetheless, the Balkans remained a site of political unrest with teeming ambition for independence and great power rivalries. At the Congress of Berlin in 1878 Gyula Andrássy (Minister of Foreign Affairs) managed to force Russia to retreat from further demands in the Balkans. As a result, Greater Bulgaria was broken up and Serbian independence was guaranteed. In that year, with Britain's support, Austria–Hungary stationed troops in Bosnia to prevent the Russians from expanding into nearby Serbia. In another measure to keep the Russians out of the Balkans, Austria–Hungary formed an alliance, the Mediterranean Entente, with Britain and Italy in 1887 and concluded mutual defence pacts with Germany in 1879 and Romania in 1883 against a possible Russian attack. Following the Congress of Berlin the European powers attempted to guarantee stability through a complex series of alliances and treaties. Anxious about Balkan instability and Russian aggression, and to counter French interests in Europe, Austria–Hungary forged a defensive alliance with Germany in October 1879 and in May 1882. In October 1882 Italy joined this partnership in the Triple Alliance largely because of Italy's imperial rivalries with France. Tensions between Russia and Austria–Hungary remained high, so Bismarck replaced the League of the Three Emperors with the Reinsurance Treaty with Russia to keep the Habsburgs from recklessly starting a war over Pan-Slavism. The Sandžak-Raška / Novibazar region was under Austro-Hungarian occupation between 1878 and 1909, when it was returned to the Ottoman Empire, before being ultimately divided between kingdoms of Montenegro and Serbia. On the heels of the Great Balkan Crisis, Austro-Hungarian forces occupied Bosnia and Herzegovina in August 1878 and the monarchy eventually annexed Bosnia and Herzegovina in October 1908 as a common holding of Cisleithania and Transleithania under the control of the Imperial & Royal finance ministry rather than attaching it to either territorial government. The annexation in 1908 led some in Vienna to contemplate combining Bosnia and Herzegovina with Croatia to form a third Slavic component of the monarchy. The deaths of Franz Joseph's brother, Maximilian (1867), and his only son, Rudolf, made the Emperor's nephew, Franz Ferdinand, heir to the throne. The Archduke was rumoured to have been an advocate for this trialism as a means to limit the power of the Hungarian aristocracy. A proclamation issued on the occasion of its annexation to the Habsburg monarchy in October 1908 promised these lands constitutional institutions, which should secure to their inhabitants full civil rights and a share in the management of their own affairs by means of a local representative assembly. In performance of this promise a constitution was promulgated in 1910. The principal players in the Bosnian Crisis of 1908-09 were the foreign ministers of Austria and Russia, Alois Lexa von Aehrenthal and Alexander Izvolsky. Both were motivated by political ambition; the first would emerge successful, and the latter would be broken by the crisis. Along the way, they would drag Europe to the brink of war in 1909. They would also divide Europe into the two armed camps that would go to war in July 1914. Aehrenthal had started with the assumption that the Slavic minorities could never come together, and the Balkan League would never cause any damage to Austria. He turned down an Ottoman proposal for an alliance that would include Austria, Turkey, and Romania. However, his policies alienated the Bulgarians, who turned instead to Russia and Serbia. Although Austria had no intention to embark on additional expansion to the south, Aehrenthal encouraged speculation to that effect, expecting that it would paralyze the Balkan states. Instead, it incited them to feverish activity to create a defensive block to stop Austria. A series of grave miscalculations at the highest level thus significantly strengthened Austria's enemies. In 1914, Slavic militants in Bosnia rejected Austria's plan to fully absorb the area; they assassinated the Austrian heir and precipitated World War I. Prelude On 28 June 1914, Archduke Franz Ferdinand visited the Bosnian capital, Sarajevo. A group of six assassins (Cvjetko Popović, Gavrilo Princip, Muhamed Mehmedbašić, Nedeljko Čabrinović, Trifko Grabež, Vaso Čubrilović) from the nationalist group Mlada Bosna, supplied by the Black Hand, had gathered on the street where the Archduke's motorcade would pass. Čabrinović threw a grenade at the car, but missed. It injured some people nearby, and Franz Ferdinand's convoy could carry on. The other assassins failed to act as the cars drove past them quickly. About an hour later, when Franz Ferdinand was returning from a visit at the Sarajevo Hospital, the convoy took a wrong turn into a street where Gavrilo Princip by coincidence stood. With a pistol, Princip shot and killed Franz Ferdinand and his wife Sophie. The reaction among most city-dwelling Austrian people was mild, almost indifferent. As historian Z. A. B. Zeman later wrote, "The event almost failed to make any impression whatsoever. On Sunday and Monday [June 28 and 29], the crowds in Vienna listened to music and drank wine, as if nothing had happened". The assassination excessively intensified the existing traditional religion-based ethnic hostilities in Bosnia. However, in Sarajevo itself, Austrian authorities encouraged violence against the Serb residents, which resulted in the Anti-Serb riots of Sarajevo, in which Catholic Croats and Bosnian Muslims killed two and damaged numerous Serb-owned buildings. Writer Ivo Andrić referred to the violence as the "Sarajevo frenzy of hate." Violent actions against ethnic Serbs were organized not only in Sarajevo but also in many other larger Austro-Hungarian cities in modern-day Croatia and Bosnia and Herzegovina. Austro-Hungarian authorities in Bosnia and Herzegovina imprisoned and extradited approximately 5,500 prominent Serbs, 700 to 2,200 of whom died in prison. Four hundred sixty Serbs were sentenced to death and a predominantly Muslim special militia known as the Schutzkorps was established and carried out the persecution of Serbs. Some members of the government, such as Minister of Foreign Affairs Count Leopold Berchtold and Army Commander Count Franz Conrad von Hötzendorf, had wanted to confront the resurgent Serbian nation for some years in a preventive war, but the Emperor and Hungarian prime minister István Tisza were opposed. The foreign ministry of Austro-Hungarian Empire sent ambassador László Szőgyény to Potsdam, where he inquired about the standpoint of the German Emperor on 5 July and received a supportive response. The leaders of Austria–Hungary therefore decided to confront Serbia militarily before it could incite a revolt; using the assassination as an excuse, they presented a list of ten demands called the July Ultimatum, expecting Serbia would never accept. When Serbia accepted nine of the ten demands but only partially accepted the remaining one, Austria–Hungary declared war. Franz Joseph I finally followed the urgent counsel of his top advisers. Over the course of July and August 1914, these events caused the start of World War I, as Russia mobilized in support of Serbia, setting off a series of counter-mobilizations. In support of his German ally, on Thursday, 6 August 1914, Emperor Franz Joseph signed the declaration of war on Russia. Italy initially remained neutral, despite its alliance with Austria–Hungary. In 1915, it switched to the side of the Entente powers, hoping to gain territory from its former ally. Wartime foreign policy The Austro-Hungarian Empire played a relatively passive diplomatic role in the war, as it was increasingly dominated and controlled by Germany. The only goal was to punish Serbia and try to stop the ethnic breakup of the Empire, and it completely failed. Starting in late 1916 the new Emperor Karl removed the pro-German officials and opened peace overtures to the Allies, whereby the entire war could be ended by compromise, or perhaps Austria would make a separate peace from Germany. The main effort was vetoed by Italy, which had been promised large slices of Austria for joining the Allies in 1915. Austria was only willing to turn over the Trentino region but nothing more. Karl was seen as a defeatist, which weakened his standing at home and with both the Allies and Germany. Theaters of operations The Austro-Hungarian Empire conscripted 7.8 million soldiers during WWI. General von Hötzendorf was the Chief of the Austro-Hungarian General Staff. Franz Joseph I, who was much too old to command the army, appointed Archduke Friedrich von Österreich-Teschen as Supreme Army Commander (Armeeoberkommandant), but asked him to give Von Hötzendorf freedom to take any decisions. Von Hötzendorf remained in effective command of the military forces until Emperor Karl I took the supreme command himself in late 1916 and dismissed Conrad von Hötzendorf in 1917. Meanwhile, economic conditions on the homefront deteriorated rapidly. The Empire depended on agriculture, and agriculture depended on the heavy labor of millions of men who were now in the Army. Food production fell, the transportation system became overcrowded, and industrial production could not successfully handle the overwhelming need for munitions. Germany provided a great deal of help, but it was not enough. Furthermore, the political instability of the multiple ethnic groups of Empire now ripped apart any hope for national consensus in support of the war. Increasingly there was a demand for breaking up the Empire and setting up autonomous national states based on historic language-based cultures. The new Emperor sought peace terms from the Allies, but his initiatives were vetoed by Italy. Homefront The heavily rural Empire did have a small industrial base, but its major contribution was manpower and food. Nevertheless, Austria–Hungary was more urbanized (25%) than its actual opponents in the First World War, like the Russian Empire (13.4%), Serbia (13.2%) or Romania (18.8%). Furthermore, the Austro-Hungarian Empire had also more industrialized economy and higher GDP per capita than the Kingdom of Italy, which was economically the far most developed actual opponent of the Empire. On the home front, food grew scarcer and scarcer, as did heating fuel. Hungary, with its heavy agricultural base, was somewhat better fed. The Army conquered productive agricultural areas in Romania and elsewhere, but refused to allow food shipments to civilians back home. Morale fell every year, and the diverse nationalities gave up on the Empire and looked for ways to establish their own nation states. Inflation soared, from an index of 129 in 1914 to 1589 in 1918, wiping out the cash savings of the middle-class. In terms of war damage to the economy, the war used up about 20 percent of the GDP. The dead soldiers amounted to about four percent of the 1914 labor force, and the wounded ones to another six percent. Compared all the major countries in the war, the death and casualty rate was toward the high-end regarding the present-day territory of Austria. By summer 1918, "Green Cadres" of army deserters formed armed bands in the hills of Croatia-Slavonia and civil authority disintegrated. By late October violence and massive looting erupted and there were efforts to form peasant republics. However, the Croatian political leadership was focused on creating a new state (Yugoslavia) and worked with the advancing Serbian army to impose control and end the uprisings. Serbian front 1914–1916 At the start of the war, the army was divided into two: the smaller part attacked Serbia while the larger part fought against the formidable Imperial Russian Army. The invasion of Serbia in 1914 was a disaster: by the end of the year, the Austro-Hungarian Army had taken no territory, but had lost 227,000 out of a total force of 450,000 men. However, in the autumn of 1915, the Serbian Army was defeated by the Central Powers, which led to the occupation of Serbia. Near the end of 1915, in a massive rescue operation involving more than 1,000 trips made by Italian, French and British steamers, 260,000 Serb surviving soldiers were transported to Brindisi and Corfu, where they waited for the chance of the victory of Allied Powers to reclaim their country. Corfu hosted the Serbian government in exile after the collapse of Serbia and served as a supply base to the Greek front. In April 1916 a large number of Serbian troops were transported in British and French naval vessels from Corfu to mainland Greece. The contingent numbering over 120,000 relieved a much smaller army at the Macedonian front and fought alongside British and French troops. Russian front 1914–1917 On the Eastern front, the war started out equally poorly. The government accepted the Polish proposal of establishing the Supreme National Committee as the Polish central authority within the Empire, responsible for the formation of the Polish Legions, an auxiliary military formation within the Austro-Hungarian army. The Austro-Hungarian Army was defeated at the Battle of Lemberg and the great fortress city of Przemyśl was besieged and fell in March 1915. The Gorlice–Tarnów Offensive started as a minor German offensive to relieve the pressure of the Russian numerical superiority on the Austro-Hungarians, but the cooperation of the Central Powers resulted in huge Russian losses and the total collapse of the Russian lines and their long retreat into Russia. The Russian Third Army perished. In summer 1915, the Austro-Hungarian Army, under a unified command with the Germans, participated in the successful Gorlice–Tarnów Offensive. From June 1916, the Russians focused their attacks on the Austro-Hungarian army in the Brusilov Offensive, recognizing the numerical inferiority of the Austro-Hungarian army. By the end of September 1916, Austria–Hungary mobilized and concentrated new divisions, and the successful Russian advance was halted and slowly repelled; but the Austrian armies took heavy losses (about 1 million men) and never recovered. Nevertheless, the huge losses in men and material inflicted on the Russians during the offensive contributed greatly to the revolutions of 1917, and it caused an economic crash in the Russian Empire. The Act of 5 November 1916 was proclaimed then to the Poles jointly by the Emperors Wilhelm II of Germany and Franz Joseph of Austria-Hungary. This act promised the creation of the Kingdom of Poland out of territory of Congress Poland, envisioned by its authors as a puppet state controlled by the Central Powers, with the nominal authority vested in the Regency Council. The origin of that document was the dire need to draft new recruits from German-occupied Poland for the war with Russia. Following the Armistice of 11 November 1918 ending the World War I, in spite of the previous initial total dependence of the kingdom on its sponsors, it ultimately served against their intentions as the cornerstone proto state of the nascent Second Polish Republic, the latter composed also of territories never intended by the Central Powers to be ceded to Poland. The Battle of Zborov (1917) was the first significant action of the Czechoslovak Legions, who fought for the independence of Czechoslovakia against the Austro-Hungarian army. Italian front 1915–1918 In May 1915, Italy attacked Austria–Hungary. Italy was the only military opponent of Austria–Hungary which had a similar degree of industrialization and economic level; moreover, her army was numerous (≈1,000,000 men were immediately fielded), but suffered from poor leadership, training and organization. Chief of Staff Luigi Cadorna marched his army towards the Isonzo river, hoping to seize Ljubljana, and to eventually threaten Vienna. However, the Royal Italian Army were halted on the river, where four battles took place over five months (23 June – 2 December 1915). The fight was extremely bloody and exhausting for both the contenders. On 15 May 1916, the Austrian Chief of Staff Conrad von Hötzendorf launched the Strafexpedition ("punitive expedition"): the Austrians broke through the opposing front and occupied the Asiago plateau. The Italians managed to resist and in a counteroffensive seized Gorizia on 9 August. Nonetheless, they had to stop on the Carso, a few kilometres away from the border. At this point, several months of indecisive trench warfare ensued (analogous to the Western front). As the Russian Empire collapsed as a result of the Bolshevik Revolution and Russians ended their involvement in the war, Germans and Austrians were able to move on the Western and Southern fronts much manpower from the erstwhile Eastern fighting. On 24 October 1917, Austrians (now enjoying decisive German support) attacked at Caporetto using new infiltration tactics; although they advanced more than in the direction of Venice and gained considerable supplies, they were halted and could not cross the Piave river. Italy, although suffering massive casualties, recovered from the blow, and a coalition government under Vittorio Emanuele Orlando was formed. Italy also enjoyed support by the Entente powers: by 1918, large amounts of war materials and a few auxiliary American, British, and French divisions arrived in the Italian battle zone. Cadorna was replaced by General Armando Diaz; under his command, the Italians retook the initiative and won the decisive Battle of the Piave river (15–23 June 1918), in which some 60,000 Austrian and 43,000 Italian soldiers were killed. The final battle was at Vittorio Veneto; after 4 days of stiff resistance, Italian troops crossed the Piave River, and after losing 90,000 men the defeated Austrian troops retreated in disarray pursued by the Italians. The Italians captured 448,000 Austrian-Hungarian soldiers (about one-third of the imperial-royal army), 24 of whom were generals, 5,600 cannons and mortars, and 4,000 machine guns. The armistice was signed at Villa Giusti on 3 November, in spite of Austria–Hungary already having disintegrated on 31 October 1918. Romanian front 1916–1917 On 27 August 1916, Romania declared war against Austria–Hungary. The Romanian Army crossed the borders of Eastern Hungary (Transylvania), and despite initial successes, by November 1916, the Central Powers formed by the Austro-Hungarian, German, Bulgarian, and Ottoman armies, had defeated the Romanian and Russian armies of the Entente Powers, and occupied the southern part of Romania (including Oltenia, Muntenia and Dobruja). Within 3 months of the war, the Central Powers came near Bucharest, the Romanian capital city. On 6 December, the Central Powers captured Bucharest, and part of the population moved to the unoccupied Romanian territory, in Moldavia, together with the Romanian government, royal court and public authorities, which relocated to Iași. In 1917, after several defensive victories (managing to stop the German-Austro-Hungarian advance), with Russia's withdrawal from the war following the October Revolution, Romania was forced to drop out of the war. Whereas the German army realized it needed close cooperation from the homefront, Habsburg officers saw themselves as entirely separate from the civilian world, and superior to it. When they occupied productive areas, such as southern Romania, they seized food stocks and other supplies for their own purposes and blocked any shipments intended for civilians back in the Austro-Hungarian Empire. The result was that the officers lived well, as the civilians began to starve. Vienna even transferred training units to Serbia and Poland for the sole purpose of feeding them. In all, the Army obtained about 15 percent of its cereal needs from occupied territories. Role of Hungary Although the Kingdom of Hungary comprised only 42% of the population of Austria–Hungary, the thin majority – more than 3.8 million soldiers – of the Austro-Hungarian armed forces were conscripted from the Kingdom of Hungary during the First World War. Roughly 600,000 soldiers were killed in action, and 700,000 soldiers were wounded in the war. Austria–Hungary held on for years, as the Hungarian half provided sufficient supplies for the military to continue to wage war. This was shown in a transition of power after which the Hungarian prime minister, Count István Tisza, and foreign minister, Count István Burián, had decisive influence over the internal and external affairs of the monarchy. By late 1916, food supply from Hungary became intermittent and the government sought an armistice with the Entente powers. However, this failed as Britain and France no longer had any regard for the integrity of the monarchy because of Austro-Hungarian support for Germany. Analysis of defeat Among the European great powers, in proportion to its national income, Austria-Hungary paid the lowest attention to the development and maintenance of its army. The setbacks that the Austrian army suffered in 1914 and 1915 can be attributed to a large extent by the incompetence of the Austrian high command. After attacking Serbia, its forces soon had to be withdrawn to protect its eastern frontier against Russia's invasion, while German units were engaged in fighting on the Western Front. This resulted in a greater than expected loss of men in the invasion of Serbia. Furthermore, it became evident that the Austrian high command had had no plans for possible continental war and that the army and navy were also ill-equipped to handle such a conflict. In the last two years of the war the Austro-Hungarian armed forces lost all ability to act independently of Germany. As of 7 September 1916, the German emperor was given full control of all the armed forces of the Central Powers and Austria-Hungary effectively became a satellite of Germany. The Austrians viewed the German army favorably, on the other hand by 1916 the general belief in Germany was that Germany, in its alliance with Austria–Hungary, was "shackled to a corpse". The operational capability of the Austro-Hungarian army was seriously affected by supply shortages, low morale and a high casualty rate, and by the army's composition of multiple ethnicities with different languages and customs. The last two successes for the Austrians, the Romanian Offensive and the Caporetto Offensive, were German-assisted operations. As the Dual Monarchy became more politically unstable, it became more and more dependent on German assistance. The majority of its people, other than Hungarians and German Austrians, became increasingly restless. In 1917, the Eastern front of the Entente Powers completely collapsed. In spite of this, the Austro-Hungarian Empire then withdrew from all defeated countries due to its dire economic condition, as well as signs of impeding disintegration. 1918: Demise, disintegration, dissolution By 1918, the economic situation had deteriorated. The government had failed badly on the homefront. Historian Alexander Watson reports: As the Imperial economy collapsed into severe hardship and even starvation, its multi-ethnic army lost its morale and was increasingly hard-pressed to hold its line. At the last Italian offensive, the Austro-Hungarian Army took to the field without any food and munition supply and fought without any political supports for a de facto non-existent empire. The Austro-Hungarian monarchy collapsed with dramatic speed in the autumn of 1918. Leftist and pacifist political movements organized strikes in factories, and uprisings in the army had become commonplace. These leftist or left-liberal pro-Entente maverick parties opposed the monarchy as a form of government and considered themselves internationalist rather than patriotic. Eventually, the German defeat and the minor revolutions in Vienna and Budapest gave political power to the left/liberal political parties. As the war went on, the ethnic unity declined; the Allies encouraged breakaway demands from minorities and the Empire faced disintegration. As it became apparent that the Allied powers would win World War I, nationalist movements, which had previously been calling for a greater degree of autonomy for various areas, started pressing for full independence. In the capital cities of Vienna and Budapest, the leftist and liberal movements and opposition parties strengthened and supported the separatism of ethnic minorities. The multiethnic Austro-Hungarian Empire started to disintegrate, leaving its army alone on the battlefields. The military breakdown of the Italian front marked the start of the rebellion for the numerous ethnicities who made up the multiethnic Empire, as they refused to keep on fighting for a cause that now appeared senseless. The Emperor had lost much of his power to rule, as his realm disintegrated. As one of his Fourteen Points, President Woodrow Wilson demanded that the nationalities of Austria–Hungary have the "freest opportunity to autonomous development". In response, Emperor Karl I agreed to reconvene the Imperial Parliament in 1917 and allow the creation of a confederation with each national group exercising self-governance. However, the leaders of these national groups rejected the idea; they deeply distrusted Vienna and were now determined to get independence. On 14 October 1918, Foreign Minister Baron István Burián von Rajecz asked for an armistice based on the Fourteen Points. In an apparent attempt to demonstrate good faith, Emperor Karl issued a proclamation ("Imperial Manifesto of 16 October 1918") two days later which would have significantly altered the structure of the Austrian half of the monarchy, allowing the Poles to secede and transforming the rest of Cisleithania into a federal union of Germans, Czechs, South Slavs and Ukrainians. No such proclamation could be issued in Hungary, where Hungarian aristocrats still sought to keep the kingdom intact. However, on 18 October, United States Secretary of State Robert Lansing replied that autonomy for the nationalities – the tenth of the Fourteen Points – was no longer enough. In fact, a Czechoslovak provisional government had joined the Allies on 14 October. The South Slavs in both halves of the monarchy had already declared in favor of uniting with Serbia in a large South Slav state in the 1917 Corfu Declaration signed by members of the Yugoslav Committee. The Croatians had begun disregarding orders from Budapest earlier in October. Lansing's response was, in effect, the death certificate of Austria–Hungary. During the Italian battles, the Czechoslovaks and Southern Slavs declared their independence. With defeat in the war imminent after the Italian offensive in the Battle of Vittorio Veneto on 24 October, Czech politicians peacefully took over command in Prague on 28 October (later declared the birth of Czechoslovakia) and followed up in other major cities in the next few days. On 30 October, the Slovaks did the same. On 29 October, the Slavs in both portions of what remained of Austria–Hungary proclaimed the State of Slovenes, Croats and Serbs and declared that their ultimate intention was to unite with Serbia and Montenegro in a large South Slav state. On the same day, the Czechs and Slovaks formally proclaimed the establishment of Czechoslovakia as an independent state. Alexander Watson argues that, "The Habsburg regime's doom was sealed when Wilson's response to the note, sent two and a half weeks earlier [by the foreign minister Baron István Burián von Rajecz on 14 October 1918], arrived on 20 October." Wilson rejected the continuation of the dual monarchy as a negotiable possibility. On 16 October 1918, Emperor Karl I of Austria and IV of Hungary proclaimed the People’s Manifesto, which envisaged to turn the Empire into a federal state of five Kingdoms (Austria, Hungary, Croatia, Bohemia and Polish-Galicia), in an attempt to take into account the aspirations of the Croats, Czechs, Austrian Germans, Poles, Ukrainians and Romanians without affecting the integrity of the lands of the Crown of Saint Stephen. It also promised the unification of Polish lands via an Austro-Polish solution, and an Austro-Bohemian Compromise that would transform the projected Trialism into a proposal with two additional kingdoms. The city of Trieste and its Italian territory would be granted a special status. Karl declared that his objectives were to resolve 'the needs of the Austrian people' and bring 'happiness to all [his] people' (including non-Germans), and that he had thrived to achieve peace in the 'fatherland' and to rebuild society ever since his accession to the throne. However, the People's Manifesto came too late, at a time when Austria-Hungary was collapsing near the end of the war, and was no longer perceived by the national representative bodies as an invitation to reform the monarchy but as an opportunity to carve out their own future in a self-determined way with the option of leaving the monarchy. On 17 October 1918, the Hungarian Parliament voted in favour of terminating the union with Austria. The most prominent opponent of continued union with Austria, Count Mihály Károlyi, seized power in the Aster Revolution on 31 October. Charles was all but forced to appoint Károlyi as his Hungarian prime minister. One of Károlyi's first acts was to formally repudiate the compromise agreement on 31 October, effectively terminating the personal union with Austria and thus officially dissolving the Austro-Hungarian state. By the end of October, there was nothing left of the Habsburg realm but its majority-German Danubian and Alpine provinces, and Karl's authority was being challenged even there by the German-Austrian state council. Karl's last Austrian prime minister, Heinrich Lammasch, concluded that Karl's position was untenable. Lammasch persuaded Karl that the best course was to relinquish, at least temporarily, his right to exercise sovereign authority. On 11 November, Karl issued a carefully worded proclamation in which he recognized the Austrian people's right to determine the form of the state and "relinquish(ed) every participation" in Austrian state affairs. On the day after he announced his withdrawal from Austrian politics, the German-Austrian National Council proclaimed the Republic of German Austria. Károlyi followed suit on 16 November, proclaiming the Hungarian Democratic Republic. Successor states There were two legal successor states of the former Austro–Hungarian monarchy: German Austria (which became the Republic of Austria) Hungarian Democratic Republic (which after a few other short-lived intermediaries became the Kingdom of Hungary) The 1919 Treaties of Saint-Germain-en-Laye (between the victors of World War I and Austria) and Trianon (between the victors and Hungary) regulated the new borders of Austria and Hungary, reducing them to small-sized and landlocked states. In regard to areas without a decisive national majority, the Entente powers ruled in many cases in favour of the newly emancipated independent nation-states, enabling them to claim vast territories containing sizeable German- and Hungarian-speaking populations. The decisions contained in the treaties had immense political and economic effects. The previously rapid economic growth of the imperial territories initially stalled because the new borders became major economic barriers. Many established industries and infrastructure elements were intended to satisfy the needs of an extensive realm. As a result, the emerging countries were often compelled to considerable sacrifices in order to transform their economies. A major political unease in the affected regions followed as a result of these economic difficulties, fueling in some cases extremist movements. Austria As a result, the Republic of Austria lost roughly 60% of the old Austrian Empire's territory. It also had to drop its plans for union with Germany, as it was not allowed to unite with Germany without League approval. The new Austrian state was, at least on paper, on shakier ground than Hungary. Unlike its former Hungarian partner, Austria had never been a nation in any real sense. While the Austrian state had existed in one form or another for 700 years, it was united only by loyalty to the Habsburgs. With the loss of 60% of the Austrian Empire's prewar territory, Vienna was now a lavish and oversized imperial capital lacking an empire to support it, thus being sarcastically referred to as the "national hydrocephalus". However, after a brief period of upheaval and the Allies' foreclosure of union with Germany, Austria established itself as a federal republic. Despite the temporary Anschluss with Nazi Germany, it still survives today. Adolf Hitler cited that all "Germans" – such as him and the others from Austria, etc. – should be united with Germany. Hungary By comparison, Hungary had been a nation and a state for over 900 years. Hungary, however, was severely disrupted by the loss of 72% of its territory, 64% of its population and most of its natural resources. The Hungarian Democratic Republic was short-lived and was temporarily replaced by the communist Hungarian Soviet Republic. Romanian troops ousted Béla Kun and his communist government during the Hungarian–Romanian War of 1919. In the summer of 1919, a Habsburg, Archduke Joseph August, became regent, but was forced to stand down after only two weeks when it became apparent the Allies would not recognise him. Finally, in March 1920, royal powers were entrusted to a regent, Miklós Horthy, who had been the last commanding admiral of the Austro-Hungarian Navy and had helped organize the counter-revolutionary forces. It was this government that signed the Treaty of Trianon under protest on 4 June 1920 at the Grand Trianon Palace in Versailles, France. The restored Kingdom of Hungary lost roughly 72% of the pre-war territory of the Kingdom of Hungary. Habsburg banishment Austria had passed the "Habsburg Law", which both dethroned the Habsburgs and banished all Habsburgs from Austrian territory. While Karl was banned from ever returning to Austria again, other Habsburgs could return if they gave up all claims to the defunct throne. In March and again in October 1921, ill-prepared attempts by Karl to regain the throne in Budapest collapsed. The initially wavering Horthy, after receiving threats of intervention from the Allied Powers and the Little Entente, refused his cooperation. Soon afterward, the Hungarian government nullified the Pragmatic Sanction, effectively dethroning the Habsburgs. Subsequently, the British took custody of Karl and removed him and his family to the Portuguese island of Madeira, where he died the following year. Territorial legacy Immediately after World War I The following states were formed, re-established or expanded at the dissolution of the former Austro–Hungarian monarchy: German Austria (which became the Republic of Austria) First Hungarian Republic which became the Hungarian Soviet Republic, subsequently briefly restored and replaced by the Hungarian Republic, ultimately transformed into the Kingdom of Hungary First Czechoslovak Republic, later "Czechoslovakia" Second Polish Republic, contested by the short-lived proto-states of Tarnobrzeg Republic and Polish Soviet Socialist Republic State of Slovenes, Croats and Serbs and the Kingdom of Serbia, both later absorbed into the Kingdom of Serbs, Croats and Slovenes Greater Romania Kingdom of Italy Republic of China (former Austro-Hungarian concession of Tianjin) the short-lived Ruthenian (Ukrainian and Rusyn) proto-states of West Ukrainian People's Republic (later absorbed into Ukrainian People's Republic), Hutsul Republic, Lemko Republic, Komancza Republic and the Galician Soviet Socialist Republic; all were ultimately absorbed mostly into Poland, but also into Hungary, Czechoslovakia, Romania and Yugoslavia. The Principality of Liechtenstein, which had formerly looked to Vienna for protection and whose ruling house held sizable real estate in Cisleithania, formed a customs and defense union with Switzerland, and adopted the Swiss currency instead of the Austrian. In April 1919, Vorarlberg – the westernmost province of Austria – voted by a large majority to join Switzerland; however, both the Swiss and the Allies disregarded this result. Present The following present-day countries and parts of countries were within the boundaries of Austria–Hungary when the empire was dissolved. Some other provinces of Europe had been part of the Habsburg monarchy at one time before 1867.

Anemometer

In meteorology, an anemometer () is a device that measures wind speed and direction. It is a common instrument used in weather stations. The earliest known description of an anemometer was by Italian architect and author Leon Battista Alberti (1404–1472) in 1450. History The anemometer has changed little since its development in the 15th century. Alberti is said to have invented it around 1450. In the ensuing centuries numerous others, including Robert Hooke (1635–1703), developed their own versions, with some mistakenly credited as its inventor. In 1846, Thomas Romney Robinson (1792–1882) improved the design by using four hemispherical cups and mechanical wheels. In 1926, Canadian meteorologist John Patterson (1872–1956) developed a three-cup anemometer, which was improved by Brevoort and Joiner in 1935. In 1991, Derek Weston added the ability to measure wind direction. In 1994, Andreas Pflitsch developed the sonic anemometer. Velocity anemometers Cup anemometers A simple type of anemometer was invented in 1845 by Rev Dr John Thomas Romney Robinson of Armagh Observatory. It consisted of four hemispherical cups on horizontal arms mounted on a vertical shaft. The air flow past the cups in any horizontal direction turned the shaft at a rate roughly proportional to the wind's speed. Therefore, counting the shaft's revolutions over a set time interval produced a value proportional to the average wind speed for a wide range of speeds. This type of instrument is also called a rotational anemometer. With a four-cup anemometer, the wind always has the hollow of one cup presented to it, and is blowing on the back of the opposing cup. Since a hollow hemisphere has a drag coefficient of .38 on the spherical side and 1.42 on the hollow side, more force is generated on the cup that presenting its hollow side to the wind. Because of this asymmetrical force, torque is generated on the anemometer's axis, causing it to spin. Theoretically, the anemometer's speed of rotation should be proportional to the wind speed because the force produced on an object is proportional to the speed of the gas or fluid flowing past it. However, in practice, other factors influence the rotational speed, including turbulence produced by the apparatus, increasing drag in opposition to the torque produced by the cups and support arms, and friction on the mount point. When Robinson first designed his anemometer, he asserted that the cups moved one-third of the speed of the wind, unaffected by cup size or arm length. This was apparently confirmed by some early independent experiments, but it was incorrect. Instead, the ratio of the speed of the wind and that of the cups, the anemometer factor, depends on the dimensions of the cups and arms, and can have a value between two and a little over three. Once the error was discovered, all previous experiment involving anemometers had to be repeated. The three-cup anemometer developed by Canadian John Patterson in 1926, and subsequent cup improvements by Brevoort & Joiner of the United States in 1935, led to a cupwheel design with a nearly linear response and an error of less than 3% up to . Patterson found that each cup produced maximum torque when it was at 45° to the wind flow. The three-cup anemometer also had a more constant torque and responded more quickly to gusts than the four-cup anemometer. The three-cup anemometer was further modified by Australian Dr. Derek Weston in 1991 to also measure wind direction. He added a tag to one cup, causing the cupwheel speed to increase and decrease as the tag moved alternately with and against the wind. Wind direction is calculated from these cyclical changes in speed, while wind speed is determined from the average cupwheel speed. Three-cup anemometers are currently the industry standard for wind resource assessment studies and practice. Vane anemometers One of the other forms of mechanical velocity anemometer is the vane anemometer. It may be described as a windmill or a propeller anemometer. Unlike the Robinson anemometer, whose axis of rotation is vertical, the vane anemometer must have its axis parallel to the direction of the wind and is therefore horizontal. Furthermore, since the wind varies in direction and the axis has to follow its changes, a wind vane or some other contrivance to fulfill the same purpose must be employed. A vane anemometer thus combines a propeller and a tail on the same axis to obtain accurate and precise wind speed and direction measurements from the same instrument. The speed of the fan is measured by a rev counter and converted to a windspeed by an electronic chip. Hence, volumetric flow rate may be calculated if the cross-sectional area is known. In cases where the direction of the air motion is always the same, as in ventilating shafts of mines and buildings, wind vanes known as air meters are employed, and give satisfactory results. Hot-wire anemometers Hot wire anemometers use a fine wire (on the order of several micrometres) electrically heated to some temperature above the ambient. Air flowing past the wire cools the wire. As the electrical resistance of most metals is dependent upon the temperature of the metal (tungsten is a popular choice for hot-wires), a relationship can be obtained between the resistance of the wire and the speed of the air. In most cases, they cannot be used to measure the direction of the airflow, unless coupled with a wind vane. Several ways of implementing this exist, and hot-wire devices can be further classified as CCA (constant current anemometer), CVA (constant voltage anemometer) and CTA (constant-temperature anemometer). The voltage output from these anemometers is thus the result of some sort of circuit within the device trying to maintain the specific variable (current, voltage or temperature) constant, following Ohm's law. Additionally, PWM (pulse-width modulation) anemometers are also used, wherein the velocity is inferred by the time length of a repeating pulse of current that brings the wire up to a specified resistance and then stops until a threshold "floor" is reached, at which time the pulse is sent again. Hot-wire anemometers, while extremely delicate, have extremely high frequency-response and fine spatial resolution compared to other measurement methods, and as such are almost universally employed for the detailed study of turbulent flows, or any flow in which rapid velocity fluctuations are of interest. An industrial version of the fine-wire anemometer is the thermal flow meter, which follows the same concept, but uses two pins or strings to monitor the variation in temperature. The strings contain fine wires, but encasing the wires makes them much more durable and capable of accurately measuring air, gas, and emissions flow in pipes, ducts, and stacks. Industrial applications often contain dirt that will damage the classic hot-wire anemometer. Laser Doppler anemometers In laser Doppler velocimetry, laser Doppler anemometers use a beam of light from a laser that is divided into two beams, with one propagated out of the anemometer. Particulates (or deliberately introduced seed material) flowing along with air molecules near where the beam exits reflect, or backscatter, the light back into a detector, where it is measured relative to the original laser beam. When the particles are in great motion, they produce a Doppler shift for measuring wind speed in the laser light, which is used to calculate the speed of the particles, and therefore the air around the anemometer. Ultrasonic anemometers Ultrasonic anemometers, first developed in the 1950s, use ultrasonic sound waves to measure wind velocity. They measure wind speed based on the time of flight of sonic pulses between pairs of transducers. Measurements from pairs of transducers can be combined to yield a measurement of velocity in 1-, 2-, or 3-dimensional flow. The spatial resolution is given by the path length between transducers, which is typically 10 to 20 cm. Ultrasonic anemometers can take measurements with very fine temporal resolution, 20 Hz or better, which makes them well suited for turbulence measurements. The lack of moving parts makes them appropriate for long-term use in exposed automated weather stations and weather buoys where the accuracy and reliability of traditional cup-and-vane anemometers are adversely affected by salty air or dust. Their main disadvantage is the distortion of the air flow by the structure supporting the transducers, which requires a correction based upon wind tunnel measurements to minimize the effect. An international standard for this process, ISO 16622 Meteorology—Ultrasonic anemometers/thermometers—Acceptance test methods for mean wind measurements is in general circulation. Another disadvantage is lower accuracy due to precipitation, where rain drops may vary the speed of sound. Since the speed of sound varies with temperature, and is virtually stable with pressure change, ultrasonic anemometers are also used as thermometers. Two-dimensional (wind speed and wind direction) sonic anemometers are used in applications such as weather stations, ship navigation, aviation, weather buoys and wind turbines. Monitoring wind turbines usually requires a refresh rate of wind speed measurements of 3 Hz, easily achieved by sonic anemometers. Three-dimensional sonic anemometers are widely used to measure gas emissions and ecosystem fluxes using the eddy covariance method when used with fast-response infrared gas analyzers or laser-based analyzers. Two-dimensional wind sensors are of two types: Two ultrasounds paths: These sensors have four arms. The disadvantage of this type of sensor is that when the wind comes in the direction of an ultrasound path, the arms disturb the airflow, reducing the accuracy of the resulting measurement. Three ultrasounds paths: These sensors have three arms. They give one path redundancy of the measurement which improves the sensor accuracy and reduces aerodynamic turbulence. Acoustic resonance anemometers Acoustic resonance anemometers are a more recent variant of sonic anemometer. The technology was invented by Savvas Kapartis and patented in 1999. Whereas conventional sonic anemometers rely on time of flight measurement, acoustic resonance sensors use resonating acoustic (ultrasonic) waves within a small purpose-built cavity in order to perform their measurement. Built into the cavity is an array of ultrasonic transducers, which are used to create the separate standing-wave patterns at ultrasonic frequencies. As wind passes through the cavity, a change in the wave's property occurs (phase shift). By measuring the amount of phase shift in the received signals by each transducer, and then by mathematically processing the data, the sensor is able to provide an accurate horizontal measurement of wind speed and direction. Because acoustic resonance technology enables measurement within a small cavity, the sensors tend to be typically smaller in size than other ultrasonic sensors. The small size of acoustic resonance anemometers makes them physically strong and easy to heat, and therefore resistant to icing. This combination of features means that they achieve high levels of data availability and are well suited to wind turbine control and to other uses that require small robust sensors such as battlefield meteorology. One issue with this sensor type is measurement accuracy when compared to a calibrated mechanical sensor. For many end uses, this weakness is compensated for by the sensor's longevity and the fact that it does not require recalibration once installed. Ping-pong ball anemometers A common anemometer for basic use is constructed from a ping-pong ball attached to a string. When the wind blows horizontally, it presses on and moves the ball; because ping-pong balls are very lightweight, they move easily in light winds. Measuring the angle between the string-ball apparatus and the vertical gives an estimate of the wind speed. This type of anemometer is mostly used for middle-school level instruction, which most students make on their own, but a similar device was also flown on the Phoenix Mars Lander. Pressure anemometers The first designs of anemometers that measure the pressure were divided into plate and tube classes. Plate anemometers These are the first modern anemometers. They consist of a flat plate suspended from the top so that the wind deflects the plate. In 1450, the Italian art architect Leon Battista Alberti invented the first mechanical anemometer; in 1664 it was re-invented by Robert Hooke (who is often mistakenly considered the inventor of the first anemometer). Later versions of this form consisted of a flat plate, either square or circular, which is kept normal to the wind by a wind vane. The pressure of the wind on its face is balanced by a spring. The compression of the spring determines the actual force which the wind is exerting on the plate, and this is either read off on a suitable gauge, or on a recorder. Instruments of this kind do not respond to light winds, are inaccurate for high wind readings, and are slow at responding to variable winds. Plate anemometers have been used to trigger high wind alarms on bridges. Tube anemometers James Lind's anemometer of 1775 consisted of a vertically mounted glass U tube containing a liquid manometer (pressure gauge), with one end bent out in a horizontal direction to face the wind flow and the other vertical end capped. Though the Lind was not the first it was the most practical and best known anemometer of this type. If the wind blows into the mouth of a tube it causes an increase of pressure on one side of the manometer. The wind over the open end of a vertical tube causes little change in pressure on the other side of the manometer. The resulting elevation difference in the two legs of the U tube is an indication of the wind speed. However, an accurate measurement requires that the wind speed be directly into the open end of the tube; small departures from the true direction of the wind causes large variations in the reading. The successful metal pressure tube anemometer of William Henry Dines in 1892 utilized the same pressure difference between the open mouth of a straight tube facing the wind and a ring of small holes in a vertical tube which is closed at the upper end. Both are mounted at the same height. The pressure differences on which the action depends are very small, and special means are required to register them. The recorder consists of a float in a sealed chamber partially filled with water. The pipe from the straight tube is connected to the top of the sealed chamber and the pipe from the small tubes is directed into the bottom inside the float. Since the pressure difference determines the vertical position of the float this is a measure of the wind speed. The great advantage of the tube anemometer lies in the fact that the exposed part can be mounted on a high pole, and requires no oiling or attention for years; and the registering part can be placed in any convenient position. Two connecting tubes are required. It might appear at first sight as though one connection would serve, but the differences in pressure on which these instruments depend are so minute, that the pressure of the air in the room where the recording part is placed has to be considered. Thus if the instrument depends on the pressure or suction effect alone, and this pressure or suction is measured against the air pressure in an ordinary room, in which the doors and windows are carefully closed and a newspaper is then burnt up the chimney, an effect may be produced equal to a wind of 10 mi/h (16 km/h); and the opening of a window in rough weather, or the opening of a door, may entirely alter the registration. While the Dines anemometer had an error of only 1% at , it did not respond very well to low winds due to the poor response of the flat plate vane required to turn the head into the wind. In 1918 an aerodynamic vane with eight times the torque of the flat plate overcame this problem. Pitot tube static anemometers Modern tube anemometers use the same principle as in the Dines anemometer but using a different design. The implementation uses a pitot-static tube which is a pitot tube with two ports, pitot and static, that is normally used in measuring the airspeed of aircraft. The pitot port measures the dynamic pressure of the open mouth of a tube with pointed head facing wind, and the static port measures the static pressure from small holes along the side on that tube. The pitot tube is connected to a tail so that it always makes the tube's head to face the wind. Additionally, the tube is heated to prevent rime ice formation on the tube. There are two lines from the tube down to the devices to measure the difference in pressure of the two lines. The measurement devices can be manometers, pressure transducers, or analog chart recorders. Effect of density on measurements In the tube anemometer the dynamic pressure is actually being measured, although the scale is usually graduated as a velocity scale. If the actual air density differs from the calibration value, due to differing temperature, elevation or barometric pressure, a correction is required to obtain the actual wind speed. Approximately 1.5% (1.6% above 6,000 feet) should be added to the velocity recorded by a tube anemometer for each 1000 ft (5% for each kilometer) above sea-level. Effect of icing At airports, it is essential to have accurate wind data under all conditions, including freezing precipitation. Anemometry is also required in monitoring and controlling the operation of wind turbines, which in cold environments are prone to in-cloud icing. Icing alters the aerodynamics of an anemometer and may entirely block it from operating. Therefore, anemometers used in these applications must be internally heated. Both cup anemometers and sonic anemometers are presently available with heated versions. Instrument location In order for wind speeds to be comparable from location to location, the effect of the terrain needs to be considered, especially in regard to height. Other considerations are the presence of trees, and both natural canyons and artificial canyons (urban buildings). The standard anemometer height in open rural terrain is 10 meters.

Archaeopteryx

Archaeopteryx (; ), sometimes referred to by its German name, "" ( Primeval Bird), is a genus of avian dinosaurs. The name derives from the ancient Greek (archaīos), meaning "ancient", and (ptéryx), meaning "feather" or "wing". Between the late 19th century and the early 21st century, Archaeopteryx was generally accepted by palaeontologists and popular reference books as the oldest known bird (member of the group Avialae). Older potential avialans have since been identified, including Anchiornis, Xiaotingia, and Aurornis. Archaeopteryx lived in the Late Jurassic around 150 million years ago, in what is now southern Germany, during a time when Europe was an archipelago of islands in a shallow warm tropical sea, much closer to the equator than it is now. Similar in size to a Eurasian magpie, with the largest individuals possibly attaining the size of a raven, the largest species of Archaeopteryx could grow to about in length. Despite their small size, broad wings, and inferred ability to fly or glide, Archaeopteryx had more in common with other small Mesozoic dinosaurs than with modern birds. In particular, they shared the following features with the dromaeosaurids and troodontids: jaws with sharp teeth, three fingers with claws, a long bony tail, hyperextensible second toes ("killing claw"), feathers (which also suggest warm-bloodedness), and various features of the skeleton. These features make Archaeopteryx a clear candidate for a transitional fossil between non-avian dinosaurs and birds. Thus, Archaeopteryx plays an important role, not only in the study of the origin of birds, but in the study of dinosaurs. It was named from a single feather in 1861, the identity of which has been controversial. That same year, the first complete specimen of Archaeopteryx was announced. Over the years, ten more fossils of Archaeopteryx have surfaced. Despite variation among these fossils, most experts regard all the remains that have been discovered as belonging to a single species, although this is still debated. Archaeopteryx was long considered to be the beginning of the evolutionary tree of birds. However, in recent years, the discovery of several small, feathered dinosaurs has created a mystery for palaeontologists, raising questions about which animals are the ancestors of modern birds and which are their relatives. Most of these eleven fossils include impressions of feathers. Because these feathers are of an advanced form (flight feathers), these fossils are evidence that the evolution of feathers began before the Late Jurassic. The type specimen of Archaeopteryx was discovered just two years after Charles Darwin published On the Origin of Species. Archaeopteryx seemed to confirm Darwin's theories and has since become a key piece of evidence for the origin of birds, the transitional fossils debate, and confirmation of evolution. History of discovery Over the years, twelve body fossil specimens of Archaeopteryx have been found. All of the fossils come from the limestone deposits, quarried for centuries, near , Germany. The initial discovery, a single feather, was unearthed in 1860 or 1861 and described in 1861 by . It is currently located at the Natural History Museum of Berlin. Though it was the initial holotype, there were indications that it might not have been from the same animal as the body fossils. In 2019 it was reported that laser imaging had revealed the structure of the quill (which had not been visible since some time after the feather was described), and that the feather was inconsistent with the morphology of all other Archaeopteryx feathers known, leading to the conclusion that it originated from another dinosaur. This conclusion was challenged in 2020 as being unlikely; the feather was identified on the basis of morphology as most likely having been an upper major primary covert feather. The first skeleton, known as the London Specimen (BMNH 37001), was unearthed in 1861 near , Germany, and perhaps given to local physician in return for medical services. He then sold it for £700 (roughly £83,000 in 2020) to the Natural History Museum in London, where it remains. Missing most of its head and neck, it was described in 1863 by Richard Owen as Archaeopteryx macrura, allowing for the possibility it did not belong to the same species as the feather. In the subsequent fourth edition of his On the Origin of Species, Charles Darwin described how some authors had maintained "that the whole class of birds came suddenly into existence during the eocene period; but now we know, on the authority of Professor Owen, that a bird certainly lived during the deposition of the upper greensand; and still more recently, that strange bird, the Archaeopteryx, with a long lizard-like tail, bearing a pair of feathers on each joint, and with its wings furnished with two free claws, has been discovered in the oolitic slates of Solnhofen. Hardly any recent discovery shows more forcibly than this how little we as yet know of the former inhabitants of the world." The Greek word () means 'ancient, primeval'. primarily means 'wing', but it can also be just 'feather'. Meyer suggested this in his description. At first he referred to a single feather which appeared to resemble a modern bird's remex (wing feather), but he had heard of and been shown a rough sketch of the London specimen, to which he referred as a "" ("skeleton of an animal covered in similar feathers"). In German, this ambiguity is resolved by the term which does not necessarily mean a wing used for flying. was the favoured translation of Archaeopteryx among German scholars in the late nineteenth century. In English, 'ancient pinion' offers a rough approximation to this. Since then, twelve specimens have been recovered: The Berlin Specimen (HMN 1880/81) was discovered in 1874 or 1875 on the Blumenberg near , Germany, by farmer Jakob Niemeyer. He sold this precious fossil for the money to buy a cow in 1876, to innkeeper Johann Dörr, who again sold it to Ernst Otto Häberlein, the son of K. Häberlein. Placed on sale between 1877 and 1881, with potential buyers including O. C. Marsh of Yale University's Peabody Museum, it eventually was bought for 20,000 Goldmark by the Berlin's Natural History Museum, where it now is displayed. The transaction was financed by Ernst Werner von Siemens, founder of the company that bears his name. Described in 1884 by Wilhelm Dames, it is the most complete specimen, and the first with a complete head. In 1897 it was named by Dames as a new species, A. siemensii; though often considered a synonym of A. lithographica, several 21st century studies have concluded that it is a distinct species which includes the Berlin, Munich, and Thermopolis specimens. Composed of a torso, the Maxberg Specimen (S5) was discovered in 1956 near Langenaltheim; it was brought to the attention of professor Florian Heller in 1958 and described by him in 1959. The specimen is missing its head and tail, although the rest of the skeleton is mostly intact. Although it was once exhibited at the Maxberg Museum in Solnhofen, it is currently missing. It belonged to Eduard Opitsch, who loaned it to the museum until 1974. After his death in 1991, it was discovered that the specimen was missing and may have been stolen or sold. The Haarlem Specimen (TM 6428/29, also known as the Teylers Specimen) was discovered in 1855 near , Germany, and described as a Pterodactylus crassipes in 1857 by Meyer. It was reclassified in 1970 by John Ostrom and is currently located at the Teylers Museum in Haarlem, the Netherlands. It was the very first specimen found, but was incorrectly classified at the time. It is also one of the least complete specimens, consisting mostly of limb bones, isolated cervical vertebrae, and ribs. In 2017 it was named as a separate genus Ostromia, considered more closely related to Anchiornis from China. The Eichstätt Specimen (JM 2257) was discovered in 1951 near Workerszell, Germany, and described by Peter Wellnhofer in 1974. Currently located at the Jura Museum in Eichstätt, Germany, it is the smallest known specimen and has the second-best head. It is possibly a separate genus (Jurapteryx recurva) or species (A. recurva). The Solnhofen Specimen (unnumbered specimen) was discovered in the 1970s near Eichstätt, Germany, and described in 1988 by Wellnhofer. Currently located at the Bürgermeister-Müller-Museum in Solnhofen, it originally was classified as Compsognathus by an amateur collector, the same mayor Friedrich Müller after which the museum is named. It is the largest specimen known and may belong to a separate genus and species, Wellnhoferia grandis. It is missing only portions of the neck, tail, backbone, and head. The Munich Specimen (BSP 1999 I 50, formerly known as the Solenhofer-Aktien-Verein Specimen) was discovered on 3 August 1992 near Langenaltheim and described in 1993 by Wellnhofer. It is currently located at the Paläontologisches Museum München in Munich, to which it was sold in 1999 for 1.9 million Deutschmark. What was initially believed to be a bony sternum turned out to be part of the coracoid, but a cartilaginous sternum may have been present. Only the front of its face is missing. It has been used as the basis for a distinct species, A. bavarica, but more recent studies suggest it belongs to A. siemensii. An eighth, fragmentary specimen was discovered in 1990 in the younger Mörnsheim Formation at Daiting, Suevia. Therefore, it is known as the Daiting Specimen, and had been known since 1996 only from a cast, briefly shown at the Naturkundemuseum in Bamberg. The original was purchased by palaeontologist Raimund Albertsdörfer in 2009. It was on display for the first time with six other original fossils of Archaeopteryx at the Munich Mineral Show in October 2009. The Daiting Specimen was subsequently named Archaeopteryx albersdoerferi by Kundrat et al. (2018). After a lengthy period in a closed private collection, it was moved to the Museum of Evolution at Knuthenborg Safaripark (Denmark) in 2022, where it has since been on display and also been made available for researchers. Another fragmentary fossil was found in 2000. It is in private possession and, since 2004, on loan to the Bürgermeister-Müller Museum in Solnhofen, so it is called the Bürgermeister-Müller Specimen; the institute itself officially refers to it as the "Exemplar of the families Ottman & Steil, Solnhofen". As the fragment represents the remains of a single wing of Archaeopteryx, it is colloquially known as "chicken wing". Long in a private collection in Switzerland, the Thermopolis Specimen (WDC CSG 100) was discovered in Bavaria and described in 2005 by Mayr, Pohl, and Peters. Donated to the Wyoming Dinosaur Center in Thermopolis, Wyoming, it has the best-preserved head and feet; most of the neck and the lower jaw have not been preserved. The "Thermopolis" specimen was described on 2 December 2005 Science journal article as "A well-preserved Archaeopteryx specimen with theropod features"; it shows that Archaeopteryx lacked a reversed toe—a universal feature of birds—limiting its ability to perch on branches and implying a terrestrial or trunk-climbing lifestyle. This has been interpreted as evidence of theropod ancestry. In 1988, Gregory S. Paul claimed to have found evidence of a hyperextensible second toe, but this was not verified and accepted by other scientists until the Thermopolis specimen was described. "Until now, the feature was thought to belong only to the species' close relatives, the deinonychosaurs." The Thermopolis Specimen was assigned to Archaeopteryx siemensii in 2007. The specimen is considered to represent the most complete and best-preserved Archaeopteryx remains yet. The discovery of an eleventh specimen was announced in 2011; it was described in 2014. It is one of the more complete specimens, but is missing much of the skull and one forelimb. It is privately owned and has yet to be given a name. Palaeontologists of the Ludwig Maximilian University of Munich studied the specimen, which revealed previously unknown features of the plumage, such as feathers on both the upper and lower legs and metatarsus, and the only preserved tail tip. A twelfth specimen had been discovered by an amateur collector in 2010 at the Schamhaupten quarry, but the finding was only announced in February 2014. It was scientifically described in 2018. It represents a complete and mostly articulated skeleton with skull. It is the only specimen lacking preserved feathers. It is from the Painten Formation and somewhat older than the other specimens. Authenticity Beginning in 1985, an amateur group including astronomer Fred Hoyle and physicist Lee Spetner, published a series of papers claiming that the feathers on the Berlin and London specimens of Archaeopteryx were forged. Their claims were repudiated by Alan J. Charig and others at the Natural History Museum in London. Most of their supposed evidence for a forgery was based on unfamiliarity with the processes of lithification; for example, they proposed that, based on the difference in texture associated with the feathers, feather impressions were applied to a thin layer of cement, without realizing that feathers themselves would have caused a textural difference. They also misinterpreted the fossils, claiming that the tail was forged as one large feather, when visibly this is not the case. In addition, they claimed that the other specimens of Archaeopteryx known at the time did not have feathers, which is incorrect; the Maxberg and Eichstätt specimens have obvious feathers. They also expressed disbelief that slabs would split so smoothly, or that one half of a slab containing fossils would have good preservation, but not the counterslab. These are common properties of Solnhofen fossils, because the dead animals would fall onto hardened surfaces, which would form a natural plane for the future slabs to split along and would leave the bulk of the fossil on one side and little on the other. Finally, the motives they suggested for a forgery are not strong, and are contradictory; one is that Richard Owen wanted to forge evidence in support of Charles Darwin's theory of evolution, which is unlikely given Owen's views toward Darwin and his theory. The other is that Owen wanted to set a trap for Darwin, hoping the latter would support the fossils so Owen could discredit him with the forgery; this is unlikely because Owen wrote a detailed paper on the London specimen, so such an action would certainly backfire. Charig et al. pointed to the presence of hairline cracks in the slabs running through both rock and fossil impressions, and mineral growth over the slabs that had occurred before discovery and preparation, as evidence that the feathers were original. Spetner et al. then attempted to show that the cracks would have propagated naturally through their postulated cement layer, but neglected to account for the fact that the cracks were old and had been filled with calcite, and thus were not able to propagate. They also attempted to show the presence of cement on the London specimen through X-ray spectroscopy, and did find something that was not rock; it was not cement either, and is most probably a fragment of silicone rubber left behind when moulds were made of the specimen. Their suggestions have not been taken seriously by palaeontologists, as their evidence was largely based on misunderstandings of geology, and they never discussed the other feather-bearing specimens, which have increased in number since then. Charig et al. reported a discolouration: a dark band between two layers of limestone – they say it is the product of sedimentation. It is natural for limestone to take on the colour of its surroundings and most limestones are coloured (if not colour banded) to some degree, so the darkness was attributed to such impurities. They also mention that a complete absence of air bubbles in the rock slabs is further proof that the specimen is authentic. Description Most of the specimens of Archaeopteryx that have been discovered come from the Solnhofen limestone in Bavaria, southern Germany, which is a , a rare and remarkable geological formation known for its superbly detailed fossils laid down during the early Tithonian stage of the Jurassic period, approximately 150.8–148.5million years ago. Archaeopteryx was roughly the size of a raven, with broad wings that were rounded at the ends and a long tail compared to its body length. It could reach up to in body length and in wingspan, with an estimated mass of . Archaeopteryx feathers, although less documented than its other features, were very similar in structure to modern-day bird feathers. Despite the presence of numerous avian features, Archaeopteryx had many non-avian theropod dinosaur characteristics. Unlike modern birds, Archaeopteryx had small teeth, as well as a long bony tail, features which Archaeopteryx shared with other dinosaurs of the time. Because it displays features common to both birds and non-avian dinosaurs, Archaeopteryx has often been considered a link between them. In the 1970s, John Ostrom, following Thomas Henry Huxley's lead in 1868, argued that birds evolved within theropod dinosaurs and Archaeopteryx was a critical piece of evidence for this argument; it had several avian features, such as a wishbone, flight feathers, wings, and a partially reversed first toe along with dinosaur and theropod features. For instance, it has a long ascending process of the ankle bone, interdental plates, an obturator process of the ischium, and long chevrons in the tail. In particular, Ostrom found that Archaeopteryx was remarkably similar to the theropod family Dromaeosauridae. Archaeopteryx had three separate digits on each fore-leg each ending with a "claw". Few birds have such features. Some birds, such as ducks, swans, Jacanas (Jacana sp.), and the hoatzin (Opisthocomus hoazin), have them concealed beneath their leg-feathers. Plumage Specimens of Archaeopteryx were most notable for their well-developed flight feathers. They were markedly asymmetrical and showed the structure of flight feathers in modern birds, with vanes given stability by a barb-barbule-barbicel arrangement. The tail feathers were less asymmetrical, again in line with the situation in modern birds and also had firm vanes. The thumb did not yet bear a separately movable tuft of stiff feathers. The body plumage of Archaeopteryx is less well-documented and has only been properly researched in the well-preserved Berlin specimen. Thus, as more than one species seems to be involved, the research into the Berlin specimen's feathers does not necessarily hold true for the rest of the species of Archaeopteryx. In the Berlin specimen, there are "trousers" of well-developed feathers on the legs; some of these feathers seem to have a basic contour feather structure, but are somewhat decomposed (they lack barbicels as in ratites). In part they are firm and thus capable of supporting flight. A patch of pennaceous feathers is found running along its back, which was quite similar to the contour feathers of the body plumage of modern birds in being symmetrical and firm, although not as stiff as the flight-related feathers. Apart from that, the feather traces in the Berlin specimen are limited to a sort of "proto-down" not dissimilar to that found in the dinosaur Sinosauropteryx: decomposed and fluffy, and possibly even appearing more like fur than feathers in life (although not in their microscopic structure). These occur on the remainder of the body—although some feathers did not fossilize and others were obliterated during preparation, leaving bare patches on specimens—and the lower neck. There is no indication of feathering on the upper neck and head. While these conceivably may have been nude, this may still be an artefact of preservation. It appears that most Archaeopteryx specimens became embedded in anoxic sediment after drifting some time on their backs in the sea—the head, neck and the tail are generally bent downward, which suggests that the specimens had just started to rot when they were embedded, with tendons and muscle relaxing so that the characteristic shape (death pose) of the fossil specimens was achieved. This would mean that the skin already was softened and loose, which is bolstered by the fact that in some specimens the flight feathers were starting to detach at the point of embedding in the sediment. So it is hypothesized that the pertinent specimens moved along the sea bed in shallow water for some time before burial, the head and upper neck feathers sloughing off, while the more firmly attached tail feathers remained. Colouration In 2011, graduate student Ryan Carney and colleagues performed the first colour study on an Archaeopteryx specimen. Using scanning electron microscopy technology and energy-dispersive X-ray analysis, the team was able to detect the structure of melanosomes in the isolated feather specimen described in 1861. The resultant measurements were then compared to those of 87modern bird species, and the original colour was calculated with a 95% likelihood to be black. The feather was determined to be black throughout, with heavier pigmentation in the distal tip. The feather studied was most probably a dorsal covert, which would have partly covered the primary feathers on the wings. The study does not mean that Archaeopteryx was entirely black, but suggests that it had some black colouration which included the coverts. Carney pointed out that this is consistent with what we know of modern flight characteristics, in that black melanosomes have structural properties that strengthen feathers for flight. In a 2013 study published in the Journal of Analytical Atomic Spectrometry, new analyses of Archaeopteryxs feathers revealed that the animal may have had complex light- and dark-coloured plumage, with heavier pigmentation in the distal tips and outer vanes. This analysis of colour distribution was based primarily on the distribution of sulphate within the fossil. An author on the previous Archaeopteryx colour study argued against the interpretation of such biomarkers as an indicator of eumelanin in the full Archaeopteryx specimen. Carney and other colleagues also argued against the 2013 study's interpretation of the sulphate and trace metals, and in a 2020 study published in Scientific Reports demonstrated that the isolated covert feather was entirely matte black (as opposed to black and white, or iridescent) and that the remaining "plumage patterns of Archaeopteryx remain unknown". Classification Today, fossils of the genus Archaeopteryx are usually assigned to one or two species, A. lithographica and A. siemensii, but their taxonomic history is complicated. Ten names have been published for the handful of specimens. As interpreted today, the name A. lithographica only referred to the single feather described by Meyer. In 1954 Gavin de Beer concluded that the London specimen was the holotype. In 1960, Swinton accordingly proposed that the name Archaeopteryx lithographica be placed on the official genera list making the alternative names Griphosaurus and Griphornis invalid. The ICZN, implicitly accepting De Beer's standpoint, did indeed suppress the plethora of alternative names initially proposed for the first skeleton specimens, which mainly resulted from the acrimonious dispute between Meyer and his opponent Johann Andreas Wagner (whose Griphosaurus problematicus – 'problematic riddle-lizard' – was a vitriolic sneer at Meyer's Archaeopteryx). In addition, in 1977, the Commission ruled that the first species name of the Haarlem specimen, crassipes, described by Meyer as a pterosaur before its true nature was realized, was not to be given preference over lithographica in instances where scientists considered them to represent the same species. It has been noted that the feather, the first specimen of Archaeopteryx described, does not correspond well with the flight-related feathers of Archaeopteryx. It certainly is a flight feather of a contemporary species, but its size and proportions indicate that it may belong to another, smaller species of feathered theropod, of which only this feather is known so far. As the feather had been designated the type specimen, the name Archaeopteryx should then no longer be applied to the skeletons, thus creating significant nomenclatorial confusion. In 2007, two sets of scientists therefore petitioned the ICZN requesting that the London specimen explicitly be made the type by designating it as the new holotype specimen, or neotype. This suggestion was upheld by the ICZN after four years of debate, and the London specimen was designated the neotype on 3 October 2011. Below is a cladogram published in 2013 by Godefroit et al. Species It has been argued that all the specimens belong to the same species, A. lithographica. Differences do exist among the specimens, and while some researchers regard these as due to the different ages of the specimens, some may be related to actual species diversity. In particular, the Munich, Eichstätt, Solnhofen, and Thermopolis specimens differ from the London, Berlin, and Haarlem specimens in being smaller or much larger, having different finger proportions, having more slender snouts lined with forward-pointing teeth, and the possible presence of a sternum. Due to these differences, most individual specimens have been given their own species name at one point or another. The Berlin specimen has been designated as Archaeornis siemensii, the Eichstätt specimen as Jurapteryx recurva, the Munich specimen as Archaeopteryx bavarica, and the Solnhofen specimen as Wellnhoferia grandis. In 2007, a review of all well-preserved specimens including the then-newly discovered Thermopolis specimen concluded that two distinct species of Archaeopteryx could be supported: A. lithographica (consisting of at least the London and Solnhofen specimens), and A. siemensii (consisting of at least the Berlin, Munich, and Thermopolis specimens). The two species are distinguished primarily by large flexor tubercles on the foot claws in A. lithographica (the claws of A. siemensii specimens being relatively simple and straight). A. lithographica also had a constricted portion of the crown in some teeth and a stouter metatarsus. A supposed additional species, Wellnhoferia grandis (based on the Solnhofen specimen), seems to be indistinguishable from A. lithographica except in its larger size. Synonyms If two names are given, the first denotes the original describer of the "species", the second the author on whom the given name combination is based. As always in zoological nomenclature, putting an author's name in parentheses denotes that the taxon was originally described in a different genus.

Phylogenetic position Modern palaeontology has often classified Archaeopteryx as the most primitive bird. However, it is not thought to be a true ancestor of modern birds, but rather a close relative of that ancestor. Nonetheless, Archaeopteryx was often used as a model of the true ancestral bird. Several authors have done so. Lowe (1935) and Thulborn (1984) questioned whether Archaeopteryx truly was the first bird. They suggested that Archaeopteryx was a dinosaur that was no more closely related to birds than were other dinosaur groups. Kurzanov (1987) suggested that Avimimus was more likely to be the ancestor of all birds than Archaeopteryx. Barsbold (1983) and Zweers and Van den Berge (1997) noted that many maniraptoran lineages are extremely birdlike, and they suggested that different groups of birds may have descended from different dinosaur ancestors. The discovery of the closely related Xiaotingia in 2011 led to new phylogenetic analyses that suggested that Archaeopteryx is a deinonychosaur rather than an avialan, and therefore, not a "bird" under most common uses of that term. A more thorough analysis was published soon after to test this hypothesis, and failed to arrive at the same result; it found Archaeopteryx in its traditional position at the base of Avialae, while Xiaotingia was recovered as a basal dromaeosaurid or troodontid. The authors of the follow-up study noted that uncertainties still exist, and that it may not be possible to state confidently whether or not Archaeopteryx is a member of Avialae or not, barring new and better specimens of relevant species. Phylogenetic studies conducted by Senter, et al. (2012) and Turner, Makovicky, and Norell (2012) also found Archaeopteryx to be more closely related to living birds than to dromaeosaurids and troodontids. On the other hand, Godefroit et al. (2013) recovered Archaeopteryx as more closely related to dromaeosaurids and troodontids in the analysis included in their description of Eosinopteryx brevipenna. The authors used a modified version of the matrix from the study describing Xiaotingia, adding Jinfengopteryx elegans and Eosinopteryx brevipenna to it, as well as adding four additional characters related to the development of the plumage. Unlike the analysis from the description of Xiaotingia, the analysis conducted by Godefroit, et al. did not find Archaeopteryx to be related particularly closely to Anchiornis and Xiaotingia, which were recovered as basal troodontids instead. Agnolín and Novas (2013) found Archaeopteryx and (possibly synonymous) Wellnhoferia to be form a clade sister to the lineage including Jeholornis and Pygostylia, with Microraptoria, Unenlagiinae, and the clade containing Anchiornis and Xiaotingia being successively closer outgroups to the Avialae (defined by the authors as the clade stemming from the last common ancestor of Archaeopteryx and Aves). Another phylogenetic study by Godefroit, et al., using a more inclusive matrix than the one from the analysis in the description of Eosinopteryx brevipenna, also found Archaeopteryx to be a member of Avialae (defined by the authors as the most inclusive clade containing Passer domesticus, but not Dromaeosaurus albertensis or Troodon formosus). Archaeopteryx was found to form a grade at the base of Avialae with Xiaotingia, Anchiornis, and Aurornis. Compared to Archaeopteryx, Xiaotingia was found to be more closely related to extant birds, while both Anchiornis and Aurornis were found to be more distantly so. Hu et al. (2018), Wang et al. (2018) and Hartman et al. (2019) found Archaeopteryx to have been a deinonychosaur instead of an avialan. More specifically, it and closely related taxa were considered basal deinonychosaurs, with dromaeosaurids and troodontids forming together a parallel lineage within the group. Because Hartman et al. found Archaeopteryx isolated in a group of flightless deinonychosaurs (otherwise considered "anchiornithids"), they considered it highly probable that this animal evolved flight independently from bird ancestors (and from Microraptor and Yi). The following cladogram illustrates their hypothesis regarding the position of Archaeopteryx: The authors, however, found that the Archaeopteryx being an avialan was only slightly less likely than this hypothesis, and as likely as Archaeopterygidae and Troodontidae being sister clades. Palaeobiology Flight As in the wings of modern birds, the flight feathers of Archaeopteryx were somewhat asymmetrical and the tail feathers were rather broad. This implies that the wings and tail were used for lift generation, but it is unclear whether Archaeopteryx was capable of flapping flight or simply a glider. The lack of a bony breastbone suggests that Archaeopteryx was not a very strong flier, but flight muscles might have attached to the thick, boomerang-shaped wishbone, the platelike coracoids, or perhaps, to a cartilaginous sternum. The sideways orientation of the glenoid (shoulder) joint between scapula, coracoid, and humerus—instead of the dorsally angled arrangement found in modern birds—may indicate that Archaeopteryx was unable to lift its wings above its back, a requirement for the upstroke found in modern flapping flight. According to a study by Philip Senter in 2006, Archaeopteryx was indeed unable to use flapping flight as modern birds do, but it may well have used a downstroke-only flap-assisted gliding technique. However, a more recent study solves this issue by suggesting a different flight stroke configuration for non-avian flying theropods.Archaeopteryx wings were relatively large, which would have resulted in a low stall speed and reduced turning radius. The short and rounded shape of the wings would have increased drag, but also could have improved its ability to fly through cluttered environments such as trees and brush (similar wing shapes are seen in birds that fly through trees and brush, such as crows and pheasants). The presence of "hind wings", asymmetrical flight feathers stemming from the legs similar to those seen in dromaeosaurids such as Microraptor, also would have added to the aerial mobility of Archaeopteryx. The first detailed study of the hind wings by Longrich in 2006, suggested that the structures formed up to 12% of the total airfoil. This would have reduced stall speed by up to 6% and turning radius by up to 12%. The feathers of Archaeopteryx were asymmetrical. This has been interpreted as evidence that it was a flyer, because flightless birds tend to have symmetrical feathers. Some scientists, including Thomson and Speakman, have questioned this. They studied more than 70 families of living birds, and found that some flightless types do have a range of asymmetry in their feathers, and that the feathers of Archaeopteryx fall into this range. The degree of asymmetry seen in Archaeopteryx is more typical for slow flyers than for flightless birds. In 2010, Robert L. Nudds and Gareth J. Dyke in the journal Science published a paper in which they analysed the rachises of the primary feathers of Confuciusornis and Archaeopteryx. The analysis suggested that the rachises on these two genera were thinner and weaker than those of modern birds relative to body mass. The authors determined that Archaeopteryx and Confuciusornis, were unable to use flapping flight. This study was criticized by Philip J. Currie and Luis Chiappe. Chiappe suggested that it is difficult to measure the rachises of fossilized feathers, and Currie speculated that Archaeopteryx and Confuciusornis must have been able to fly to some degree, as their fossils are preserved in what is believed to have been marine or lake sediments, suggesting that they must have been able to fly over deep water. Gregory Paul also disagreed with the study, arguing in a 2010 response that Nudds and Dyke had overestimated the masses of these early birds, and that more accurate mass estimates allowed powered flight even with relatively narrow rachises. Nudds and Dyke had assumed a mass of for the Munich specimen Archaeopteryx, a young juvenile, based on published mass estimates of larger specimens. Paul argued that a more reasonable body mass estimate for the Munich specimen is about . Paul also criticized the measurements of the rachises themselves, noting that the feathers in the Munich specimen are poorly preserved. Nudds and Dyke reported a diameter of for the longest primary feather, which Paul could not confirm using photographs. Paul measured some of the inner primary feathers, finding rachises across. Despite these criticisms, Nudds and Dyke stood by their original conclusions. They claimed that Paul's statement, that an adult Archaeopteryx would have been a better flyer than the juvenile Munich specimen, was dubious. This, they reasoned, would require an even thicker rachis, evidence for which has not yet been presented. Another possibility is that they had not achieved true flight, but instead used their wings as aids for extra lift while running over water after the fashion of the basilisk lizard, which could explain their presence in lake and marine deposits (see Origin of avian flight). In 2004, scientists analysing a detailed CT scan of the braincase of the London Archaeopteryx concluded that its brain was significantly larger than that of most dinosaurs, indicating that it possessed the brain size necessary for flying. The overall brain anatomy was reconstructed using the scan. The reconstruction showed that the regions associated with vision took up nearly one-third of the brain. Other well-developed areas involved hearing and muscle coordination. The skull scan also revealed the structure of its inner ear. The structure more closely resembles that of modern birds than the inner ear of non-avian reptiles. These characteristics taken together suggest that Archaeopteryx had the keen sense of hearing, balance, spatial perception, and coordination needed to fly. Archaeopteryx had a cerebrum-to-brain-volume ratio 78% of the way to modern birds from the condition of non-coelurosaurian dinosaurs such as Carcharodontosaurus or Allosaurus, which had a crocodile-like anatomy of the brain and inner ear. Newer research shows that while the Archaeopteryx brain was more complex than that of more primitive theropods, it had a more generalized brain volume among Maniraptora dinosaurs, even smaller than that of other non-avian dinosaurs in several instances, which indicates the neurological development required for flight was already a common trait in the maniraptoran clade. Recent studies of flight feather barb geometry reveal that modern birds possess a larger barb angle in the trailing vane of the feather, whereas Archaeopteryx lacks this large barb angle, indicating potentially weak flight abilities.Archaeopteryx continues to play an important part in scientific debates about the origin and evolution of birds. Some scientists see it as a semi-arboreal climbing animal, following the idea that birds evolved from tree-dwelling gliders (the "trees down" hypothesis for the evolution of flight proposed by O. C. Marsh). Other scientists see Archaeopteryx as running quickly along the ground, supporting the idea that birds evolved flight by running (the "ground up" hypothesis proposed by Samuel Wendell Williston). Still others suggest that Archaeopteryx might have been at home both in the trees and on the ground, like modern crows, and this latter view is what currently is considered best-supported by morphological characters. Altogether, it appears that the species was not particularly specialized for running on the ground or for perching. A scenario outlined by Elżanowski in 2002 suggested that Archaeopteryx used its wings mainly to escape predators by glides punctuated with shallow downstrokes to reach successively higher perches, and alternatively, to cover longer distances (mainly) by gliding down from cliffs or treetops. In March 2018, scientists reported that Archaeopteryx was likely capable of flight, but in a manner distinct and substantially different from that of modern birds. This study on Archaeopteryxs bone histology suggests that it was closest to true flying birds, and in particular to pheasants and other burst flyers. Studies of Archaeopteryx's feather sheaths revealed that like modern birds, it had a center-out, flight related molting strategy. As it was a weak flier, this was extremely advantageous in preserving its maximum flight performance. Growth An histological study by Erickson, Norell, Zhongue, and others in 2009 estimated that Archaeopteryx grew relatively slowly compared to modern birds, presumably because the outermost portions of Archaeopteryx bones appear poorly vascularized; in living vertebrates, poorly vascularized bone is correlated with slow growth rate. They also assume that all known skeletons of Archaeopteryx come from juvenile specimens. Because the bones of Archaeopteryx could not be histologically sectioned in a formal skeletochronological (growth ring) analysis, Erickson and colleagues used bone vascularity (porosity) to estimate bone growth rate. They assumed that poorly vascularized bone grows at similar rates in all birds and in Archaeopteryx. The poorly vascularized bone of Archaeopteryx might have grown as slowly as that in a mallard (2.5micrometres per day) or as fast as that in an ostrich (4.2micrometres per day). Using this range of bone growth rates, they calculated how long it would take to "grow" each specimen of Archaeopteryx to the observed size; it may have taken at least 970 days (there were 375 days in a Late Jurassic year) to reach an adult size of . The study also found that the avialans Jeholornis and Sapeornis grew relatively slowly, as did the dromaeosaurid Mahakala. The avialans Confuciusornis and Ichthyornis grew relatively quickly, following a growth trend similar to that of modern birds. One of the few modern birds that exhibit slow growth is the flightless kiwi, and the authors speculated that Archaeopteryx and the kiwi had similar basal metabolic rate. Daily activity patterns Comparisons between the scleral rings of Archaeopteryx and modern birds and reptiles indicate that it may have been diurnal, similar to most modern birds. Palaeoecology The richness and diversity of the Solnhofen limestones in which all specimens of Archaeopteryx have been found have shed light on an ancient Jurassic Bavaria strikingly different from the present day. The latitude was similar to Florida, though the climate was likely to have been drier, as evidenced by fossils of plants with adaptations for arid conditions and a lack of terrestrial sediments characteristic of rivers. Evidence of plants, although scarce, include cycads and conifers while animals found include a large number of insects, small lizards, pterosaurs, and Compsognathus. The excellent preservation of Archaeopteryx fossils and other terrestrial fossils found at Solnhofen indicates that they did not travel far before becoming preserved. The Archaeopteryx specimens found were therefore likely to have lived on the low islands surrounding the Solnhofen lagoon rather than to have been corpses that drifted in from farther away. Archaeopteryx skeletons are considerably less numerous in the deposits of Solnhofen than those of pterosaurs, of which seven genera have been found. The pterosaurs included species such as Rhamphorhynchus belonging to the Rhamphorhynchidae, the group which dominated the ecological niche currently occupied by seabirds, and which became extinct at the end of the Jurassic. The pterosaurs, which also included Pterodactylus, were common enough that it is unlikely that the specimens found are vagrants from the larger islands to the north. The islands that surrounded the Solnhofen lagoon were low lying, semi-arid, and sub-tropical with a long dry season and little rain. The closest modern analogue for the Solnhofen conditions is said to be Orca Basin in the northern Gulf of Mexico, although it is much deeper than the Solnhofen lagoons. The flora of these islands was adapted to these dry conditions and consisted mostly of low () shrubs. Contrary to reconstructions of Archaeopteryx climbing large trees, these seem to have been mostly absent from the islands; few trunks have been found in the sediments and fossilized tree pollen also is absent. The lifestyle of Archaeopteryx is difficult to reconstruct and there are several theories regarding it. Some researchers suggest that it was primarily adapted to life on the ground, while other researchers suggest that it was principally arboreal on the basis of the curvature of the claws which has since been questioned. The absence of trees does not preclude Archaeopteryx from an arboreal lifestyle, as several species of bird live exclusively in low shrubs. Various aspects of the morphology of Archaeopteryx point to either an arboreal or ground existence, including the length of its legs and the elongation in its feet; some authorities consider it likely to have been a generalist capable of feeding in both shrubs and open ground, as well as along the shores of the lagoon. It most likely hunted small prey, seizing it with its jaws if it was small enough, or with its claws if it was larger.

Adrian Lamo

Adrián Alfonso Lamo Atwood (February 20, 1981 – March 14, 2018) was an American threat analyst and hacker. Lamo first gained media attention for breaking into several high-profile computer networks, including those of The New York Times, Yahoo!, and Microsoft, culminating in his 2003 arrest. Lamo was best known for reporting U.S. soldier Chelsea Manning to Army criminal investigators in 2010 for leaking hundreds of thousands of sensitive U.S. government documents to WikiLeaks. Lamo died on March 14, 2018, at the age of 37. Early life and education Adrian Lamo was born in Malden, Massachusetts His father, Mario Ricardo Lamo, was Colombian. Adrian Lamo attended high schools in Bogotá and San Francisco, from which he did not graduate, but received a GED and was court-ordered to take courses at American River College, a community college in Sacramento County, California. Lamo began his hacking efforts by hacking games on the Commodore 64 and through phone phreaking. Activities and legal issues Lamo first became known for operating AOL watchdog site Inside-AOL.com. Security compromise Lamo was a grey hat hacker who viewed the rise of the World Wide Web with a mixture of excitement and alarm. He felt that others failed to see the importance of internet security in the early days of the World Wide Web. Lamo would break into corporate computer systems, but he never caused damage to the systems involved. Instead, he would offer to fix the security flaws free of charge, and if the flaw was not fixed, he would alert the media. Lamo hoped to be hired by a corporation to attempt to break into systems and test their security, a practice that came to be known as red teaming. However, by the time this practice was common, his felony conviction prevented him from being hired. In December 2001, Lamo was praised by Worldcom for helping to fortify their corporate security. In February 2002, he broke into the internal computer network of The New York Times, added his name to the internal database of expert sources, and used the paper's LexisNexis account to conduct research on high-profile subjects. The New York Times filed a complaint, and a warrant for Lamo's arrest was issued in August 2003 following a 15-month investigation by federal prosecutors in New York. At 10:15 a.m. on September 9, after spending a few days in hiding, he surrendered to the US Marshals in Sacramento, California. He re-surrendered to the FBI in New York City on September 11, and pleaded guilty to one felony count of computer crimes against Microsoft, LexisNexis, and The New York Times on January 8, 2004. In July 2004, Lamo was sentenced to two years' probation, with six months to be served in home detention, and ordered to pay $65,000 in restitution. He was convicted of compromising security at The New York Times, Microsoft, Yahoo!, and WorldCom. When challenged for a response to allegations that he was glamorizing crime for the sake of publicity, his response was: "Anything I could say about my person or my actions would only cheapen what they have to say for themselves". When approached for comment during his criminal case, Lamo frustrated reporters with non-sequiturs, such as "Faith manages" and "It's a beautiful day." At his sentencing, Lamo expressed remorse for harm he had caused by his intrusions. The court record quotes him as adding: "I want to answer for what I have done and do better with my life." He subsequently declared on the question-and-answer site Quora that: "We all own our actions in fullness, not just the pleasant aspects of them." Lamo accepted that he had made mistakes. DNA controversy On May 9, 2006, while 18 months into a two-year probation sentence, Lamo refused to give the United States government a blood sample, which they had demanded to record his DNA in their CODIS system. According to his attorney at the time Lamo had a religious objection to giving blood but was willing to give his DNA in another form. On June 15, 2006, lawyers for Lamo filed a motion citing the Book of Genesis as one basis for Lamo's religious opposition to the giving of blood. On June 20, 2007, Lamo's legal counsel reached a settlement agreement with the U.S. Department of Justice whereby Lamo would submit a cheek swab in place of the blood sample. WikiLeaks and Chelsea Manning In February 2009, a partial list of the anonymous donors to the WikiLeaks website was leaked and published on the WikiLeaks website. Some media sources indicated at the time that Lamo was among the donors on the list. Lamo commented on his Twitter page, "Thanks WikiLeaks, for leaking your donor list... That's dedication." In May 2010, Lamo informed U.S. Army authorities that Chelsea Manning had claimed to have leaked a large body of classified documents, including 260,000 classified United States diplomatic cables. Lamo stated that Manning also "took credit for leaking" the video footage of the July 12, 2007, Baghdad airstrike, which has since come to be known as the "Collateral Murder" video. Lamo stated that he would not have turned Manning in "if lives weren't in danger". He characterized her as "in a war zone and basically trying to vacuum up as much classified information as [she] could, and just throwing it up into the air." WikiLeaks responded by denouncing Lamo and the author of the article as "notorious felons, informers & manipulators", and said: "journalists should take care." Lamo was a volunteer "adversary characterization" analyst for Project Vigilant, a Florida-based government contractor, which encouraged him to inform the government about the alleged WikiLeaks source. The head of Project Vigilant, Chet Uber, claimed, "I'm the one who called the U.S. government... All the people who say that Adrian is a narc, he did a patriotic thing. He sees all kinds of hacks, and he was seriously worried about people dying." The Taliban insurgency later announced its intention to execute Afghan nationals named in the leaks as having cooperated with the U.S.-led coalition in Afghanistan. By that time, the United States had received months of advance warning that their names were among the leaks. Manning was arrested and incarcerated in the U.S. military justice system and later sentenced to 35 years in confinement. President Barack Obama commuted the sentence to a total of seven years, including time served. Lamo responded to the commutation with a post on Medium and an interview with U.S. News & World Report. Lamo characterized his decision to work with the government as morally ambiguous, but objectively necessary, writing that "there were no right choices that day, only less wrong ones. It was cold, it was needful, and it was no one's to make except mine." Lamo was criticized by fellow hackers, such as those at the Hackers on Planet Earth conference in 2010, who labeled him a "snitch." Another commented to Lamo, following his speech during a panel discussion, that: "from my perspective, I see what you have done as treason." Greenwald, Lamo, and Wired magazine Lamo's role in the Manning case drew criticism from Glenn Greenwald, who suggested that Lamo lied to Manning by turning her in, and then lied after the fact to cover up the circumstances of her confessions. In an article about the Manning case, Greenwald mentioned Wired reporter Kevin Poulsen's 1994 felony conviction for computer hacking and suggested that "over the years, Poulsen has served more or less as Lamo's personal media voice." In an article entitled "The Worsening Journalistic Disgrace at Wired", Greenwald wrote that Wired was "actively conceal[ing] from the public, for months on end, the key evidence [the full Lamo–Manning chat logs] in a political story that has generated headlines around the world." This drew a response from Wired: "At his most reasonable, Greenwald impugns our motives, attacks the character of our staff and carefully selects his facts and sources to misrepresent the truth and generate outrage in his readership." On July 13, 2011, Wired published the Lamo–Manning chat logs in full, stating: "The most significant of the unpublished details have now been publicly established with sufficient authority that we no longer believe any purpose is served by withholding the logs." Greenwald wrote that in his opinion the newly released logs validated his claim that Wired had concealed important evidence. Film and television On August 22, 2002, Lamo was removed from a segment of NBC Nightly News when, after being asked to demonstrate his skills for the camera, he gained access to NBC's internal network. NBC was concerned that they broke the law by taping Lamo while he possibly broke the law. Lamo was a guest on The Screen Savers five times beginning in 2002. Hackers Wanted, a documentary film focusing on Lamo's life as a hacker, was produced by Trigger Street Productions, and narrated by Kevin Spacey. Focusing on the 2003 hacking scene, the film features interviews with Kevin Rose and Steve Wozniak. The film has not been conventionally released. In May 2009, a video purporting to be a trailer for Hackers Wanted was allegedly leaked onto the Internet film site Eye Crave Network. In May 2010, an early cut of the film was leaked via BitTorrent. According to an insider, what was leaked on the Internet was very different from the newer version, which includes additional footage. On June 12, 2010, a director's cut version of the film was also leaked onto torrent sites. Lamo also appeared on Good Morning America, Fox News, Democracy Now!, Frontline, and repeatedly on KCRA-TV News as an expert on netcentric crime and incidents. He was interviewed for the documentaries We Steal Secrets: The Story of WikiLeaks and True Stories: WikiLeaks – Secrets and Lies. Lamo reconnected with Leo Laporte in 2015 as a result of a Quora article on the "dark web" for an episode of The New Screen Savers. Lamo wrote the book Ask Adrian, a collection of his best Q&A drawn from over 500 pages of Quora answers. Personal life and death Lamo was known as the "Homeless Hacker" for his reportedly transient lifestyle, claiming that he spent much of his travels couch-surfing, squatting in abandoned buildings, and traveling to Internet cafés, libraries, and universities to investigate networks, sometimes exploiting security holes. He usually preferred sleeping on couches, and when he did sleep on beds, he did not sleep under covers. He would also often wander through homes and offices in the middle of the night, by the light of a flashlight. Lamo was bisexual and volunteered for the gay and lesbian media firm PlanetOut Inc. in the mid-1990s. In 1998, Lamo was appointed to the Lesbian, Gay, Bisexual, Transgender, Queer and Questioning Youth Task Force by the San Francisco Board of Supervisors. Lamo used a wide variety of supplements and drugs throughout his life. His wife, Lauren Fisher, called his drug use "body hacking". One of Lamo's preferred supplements was 'kratom' (Mitragyna speciosa), which he used as a less-dangerous alternative to opioids. In 2001, he overdosed on prescription amphetamines. After he turned in Manning, his drug use escalated, but he later claimed that he was in recovery. In a 2004 interview with Wired, an ex-girlfriend of Lamo's described him as "very controlling", alleging "he carried a stun gun, which he used on me". The same article claimed a court had issued a restraining order against Lamo; he disputed the claim, writing: "I have never been subject to a restraining order in my life". Lamo said in a Wired article that, in May 2010, after he reported the theft of his backpack, an investigating officer noted unusual behavior and placed him under a 72-hour involuntary psychiatric hold, which was extended to a nine-day hold. Lamo said he was diagnosed with Asperger syndrome at the psychiatric ward. For a period of time in March 2011, Lamo was allegedly "in hiding", claiming that his "life was under threat" after turning in Manning. Lamo died on March 14, 2018, in Wichita, Kansas, at the age of 37. Nearly three months later, the Sedgwick County Regional Forensic Science Center reported that "Despite a complete autopsy and supplemental testing, no definitive cause of death was identified." However, many bottles of pills were found in his home. Several of the pills found there were known to cause severe health problems when combined with kratom. As a result, evidence points to an accidental death due to drug abuse.

Associate Justice of the Supreme Court of the United States

An associate justice of the Supreme Court of the United States is any justice of the Supreme Court of the United States other than the chief justice of the United States. The number of associate justices is eight, as set by the Judiciary Act of 1869. Article II, Section 2, Clause 2 of the Constitution of the United States grants plenary power to the president to nominate, and with the advice and consent (confirmation) of the Senate, appoint justices to the Supreme Court. Article III, Section 1 of the Constitution effectively grants life tenure to associate justices, and all other federal judges, which ends only when a justice dies, retires, resigns, or is impeached and convicted. Each Supreme Court justice has a single vote in deciding the cases argued before it, and the chief justice's vote counts no more than that of any other justice; however, the chief justice leads the discussion of the case among the justices. Furthermore, the chief justice—when in the majority—decides who writes the court's opinion; otherwise, the senior justice in the majority assigns the writing of a decision. The chief justice also has certain administrative responsibilities that the other justices do not and is paid slightly more ($298,500 per year as of 2023, compared to $285,400 per year for an associate justice). Associate justices have seniority in order of the date their respective commissions bear, although the chief justice is always considered to be the most senior justice. If two justices are commissioned on the same day, the elder is designated the senior justice of the two. Currently, the senior associate justice is Clarence Thomas. By tradition, when the justices are in conference deliberating the outcome of cases before the Supreme Court, the justices state their views in order of seniority. The senior associate justice is also tasked with carrying out the chief justice's duties when he is unable to, or if that office is vacant. Current associate justices There are currently eight associate justices on the Supreme Court. The justices, ordered by seniority, are: Retired associate justices An associate justice who leaves the Supreme Court after attaining the age and meeting the service requirements prescribed by federal statute () may retire rather than resign. After retirement, they keep their title, and by custom may also keep a set of chambers in the Supreme Court building, and employ law clerks. The names of retired associate justices continue to appear alongside those of the active justices in the bound volumes of Supreme Court decisions. Federal statute () provides that retired Supreme Court justices may serve—if designated and assigned by the chief justice—on panels of the U.S. courts of appeals, or on the U.S. district courts. Retired justices are not, however, authorized to take part in the consideration or decision of any cases before the Supreme Court (unlike other retired federal judges who may be permitted to do so in their former courts); neither are they known or designated as a "senior judge". When, after his retirement, William O. Douglas attempted to take a more active role than was customary, maintaining that it was his prerogative to do so because of his senior status, he was rebuffed by Chief Justice Warren Burger and admonished by the whole Court. There are currently four living retired associate justices: Sandra Day O'Connor, retired January 31, 2006; David Souter, retired June 29, 2009; Anthony Kennedy, retired July 31, 2018; and Stephen Breyer, retired June 30, 2022. Souter has served on panels of the First Circuit Courts of Appeals following his retirement, while O'Connor also served on panels of various circuit courts for several years following her retirement and prior to her later withdrawal from public life; Kennedy and Breyer have not performed any judicial duties since retiring.

https://en.wikipedia.org/wiki/Al%20Capp

Al Capp

Alfred Gerald Caplin (September 28, 1909 – November 5, 1979), better known as Al Capp, was an American cartoonist and humorist best known for the satirical comic strip Li'l Abner, which he created in 1934 and continued writing and (with help from assistants) drawing until 1977. He also wrote the comic strips Abbie an' Slats (in the years 1937–45) and Long Sam (1954). He won the National Cartoonists Society's Reuben Award in 1947 for Cartoonist of the Year, and their 1979 Elzie Segar Award, posthumously for his "unique and outstanding contribution to the profession of cartooning". Capp's comic strips dealt with urban experiences in the Northern United States until the year he introduced "Li'l Abner". Although Capp was from Connecticut, he spent 43 years writing about the fictional Southern town of Dogpatch, reaching an estimated 60 million readers in more than 900 American newspapers and 100 more papers in 28 countries internationally. M. Thomas Inge says Capp made a large personal fortune through the strip and "had a profound influence on the way the world viewed the American South". Early life and education Capp was born in New Haven, Connecticut, of East European Jewish heritage. He was the eldest child of Otto Philip Caplin (1885–1964) and Matilda (Davidson) Caplin (1884–1948). His brothers, Elliot and Jerome, were cartoonists, and his sister, Madeline, was a publicist. Capp's parents were both natives of Latvia whose families had migrated to New Haven in the 1880s. "My mother and father had been brought to this country from Russia when they were infants", wrote Capp in 1978. "Their fathers had found that the great promise of America was true – it was no crime to be a Jew." The Caplins were dirt-poor, and Capp later recalled stories of his mother going out in the night to sift through ash barrels for reusable bits of coal. In August 1919, at the age of nine, Capp was run down by a trolley car and had his left leg amputated above the knee. According to his father Otto's unpublished autobiography, young Capp was not prepared for the amputation beforehand; having been in a coma for days, he suddenly awoke to discover that his leg had been removed. He was eventually given a prosthetic leg, but only learned to use it by adopting a slow way of walking which became increasingly painful as he grew older. The childhood tragedy of losing a leg likely helped shape Capp's cynical worldview, which was darker and more sardonic than that of the average newspaper cartoonist. "I was indignant as hell about that leg", he revealed in a November 1950 interview in Time magazine. "The secret of how to live without resentment or embarrassment in a world in which I was different from everyone else", Capp philosophically wrote (in Life magazine on May 23, 1960), "was to be indifferent to that difference." The prevailing opinion among his friends was that Capp's Swiftian satire was, to some degree, a creatively channeled, compensatory response to his disability. Capp's father, a failed businessman and an amateur cartoonist, introduced him to drawing as a form of therapy. He became quite proficient, advancing mostly on his own. Among his earliest influences were Punch cartoonist–illustrator Phil May and American comic strip cartoonists Tad Dorgan, Cliff Sterrett, Rube Goldberg, Rudolph Dirks, Fred Opper, Billy DeBeck, George McManus, and Milt Gross. At about this same time, Capp became a voracious reader. According to Capp's brother Elliot, Alfred had finished all of Shakespeare and George Bernard Shaw by the time he turned 13. Among his childhood favorites were Dickens, Smollett, Mark Twain, Booth Tarkington, and later, Robert Benchley and S. J. Perelman. Capp spent five years at Bridgeport High School in Bridgeport, Connecticut, without receiving a diploma. He liked to joke about how he failed geometry for nine straight terms. His formal training came from a series of art schools in the New England area. Attending three of them in rapid succession, the impoverished Capp was thrown out of each for nonpayment of tuition—the Boston Museum School of Fine Arts, the Pennsylvania Academy of the Fine Arts, and Designers Art School in Boston—the last before launching his career. Capp already had decided to become a cartoonist. "I heard that Bud Fisher (creator of Mutt and Jeff) got $3,000 a week and was constantly marrying French countesses", Capp said. "I decided that was for me." In early 1932, Capp hitchhiked to New York City. He lived in "airless rat holes" in Greenwich Village and turned out advertising strips at $2 each while scouring the city hunting for jobs. He eventually found work at the Associated Press when he was 23 years old. By March 1932, Capp was drawing Colonel Gilfeather, a single-panel, AP-owned property created in 1930 by Dick Dorgan. Capp changed the focus and title to Mister Gilfeather but soon grew to hate the feature. He left the Associated Press in September 1932. Before leaving, he met Milton Caniff and the two became lifelong friends. Capp moved to Boston and married Catherine Wingate Cameron, whom he had met earlier in art class. She died in 2006 at the age of 96. Leaving his new wife with her parents in Amesbury, Massachusetts, he subsequently returned to New York in 1933, in the midst of the Great Depression. "I was 23, I carried a mass of drawings, and I had nearly five dollars in my pocket. People were sleeping in alleys then, willing to work at anything." There he met Ham Fisher, who hired him to ghost on Joe Palooka. During one of Fisher's extended vacations, Capp's Joe Palooka story arc introduced a stupid, coarse, oafish mountaineer named "Big Leviticus," a crude prototype. (Leviticus was much closer to Capp's later villains Lem and Luke Scragg than to the much more appealing and innocent Li'l Abner.) Also during this period, Capp was working at night on samples for the strip that eventually became Li'l Abner. He based his cast of characters on the authentic mountain-dwellers he met while hitchhiking through rural West Virginia and the Cumberland Valley as a teenager. (This was years before the Tennessee Valley Authority Act brought basic utilities such as electricity and running water to the region.) Leaving Joe Palooka, Capp sold Li'l Abner to United Feature Syndicate (later known as United Media). The feature was launched on Monday, August 13, 1934, in eight North American newspapers—including the New York Mirror—and was an immediate success. Alfred G. Caplin eventually became "Al Capp" because the syndicate felt the original would not fit in a cartoon frame. Capp had his name changed legally in 1949. His younger brother, Elliot Caplin, also became a comic strip writer, best known for co-creating the soap opera strip The Heart of Juliet Jones with artist Stan Drake and conceiving the comic strip character Broom-Hilda with cartoonist Russell Myers. Elliot also authored several off-Broadway plays, including A Nickel for Picasso (1981), which was based on and dedicated to his mother and his famous brother. Li'l Abner What began as a hillbilly burlesque soon evolved into one of the most imaginative, popular, and well-drawn strips of the twentieth century. Featuring vividly outlandish characters, bizarre situations, and equal parts suspense, slapstick, irony, satire, black humor, and biting social commentary, Li'l Abner is considered a classic of the genre. The comic strip stars Li'l Abner Yokum—the simple-minded, loutish but good-natured, and eternally innocent hayseed who lives with his parents—scrawny but superhuman Mammy Yokum, and shiftless, childlike Pappy Yokum. "Yokum" was a combination of yokel and hokum, although Capp established a deeper meaning for the name during a series of visits around 1965–1970 with comics historians George E. Turner and Michael H. Price: The Yokums live in the backwater hamlet of Dogpatch, Kentucky. Described by its creator as "an average stone-age community", Dogpatch mostly consists of hopelessly ramshackle log cabins, pine trees, "tarnip" fields, and "hawg" wallows. Whatever energy Abner had went into evading the marital goals of Daisy Mae Scragg, his sexy, well-endowed, but virtuous girlfriend, until Capp finally gave in to reader pressure and allowed the couple to marry. This newsworthy event made the cover of Life on March 31, 1952. Capp peopled his comic strip with an assortment of memorable characters, including Marryin' Sam, Hairless Joe, Lonesome Polecat, Evil-Eye Fleegle, General Bullmoose, Lena the Hyena, Senator Jack S. Phogbound (Capp's caricature of the anti-New Deal Dixiecrats), the (shudder!) Scraggs, Available Jones, Nightmare Alice, Earthquake McGoon, and a host of others. Especially notable, certainly from a G.I. point of view, are the beautiful, full-figured women such as Daisy Mae, Wolf Gal, Stupefyin' Jones, and Moonbeam McSwine (a caricature of his wife Catherine, aside from the dirt), all of whom found their way onto the painted noses of bomber planes during World War II and the Korean War. Perhaps Capp's most popular creations were the Shmoos, creatures whose incredible usefulness and generous nature made them a threat to civilization as we know it. Another famous character was Joe Btfsplk, who wants to be a loving friend but is "the world's worst jinx", bringing bad luck to all those nearby. Btfsplk (his name is "pronounced" by simply blowing a "raspberry" or Bronx cheer) always has an iconic dark cloud over his head. Dogpatch residents regularly combat the likes of city slickers, business tycoons, government officials, and intellectuals with their homespun simplicity. Situations often take the characters to other destinations, including New York City, Washington, D.C., Hollywood, tropical islands, the moon, Mars, and some purely fanciful worlds of Capp's invention, including El Passionato, Kigmyland, The Republic of Crumbumbo, Skunk Hollow, The Valley of the Shmoon, Planets Pincus Number 2 and 7, and a miserable frozen wasteland known as Lower Slobbovia, a pointedly political satire of backward nations and foreign diplomacy that remains a contemporary reference. According to cultural historian Anthony Harkins: The strip's popularity grew from an original eight papers to eventually more than 900. At its peak, Li'l Abner was estimated to have been read daily in the United States by 60 to 70 million people (the U.S. population at the time was only 180 million), with adult readers far outnumbering children. Many communities, high schools, and colleges staged Sadie Hawkins dances patterned after the similar annual event in the strip. Li'l Abner has one odd design quirk that has puzzled readers for decades: the part in his hair always faces the viewer, no matter which direction Abner is facing. In response to the question "Which side does Abner part his hair on?", Capp would answer: "Both." Capp said he finally found the right "look" for Li'l Abner with Henry Fonda's character Dave Tolliver in The Trail of the Lonesome Pine (1936). In later years, Capp always claimed to have effectively created the miniskirt, when he first put one on Daisy Mae in the 1930s. Parodies, toppers, and alternate strips Li'l Abner also features a comic strip-within-the-strip: Fearless Fosdick is a parody of Chester Gould's Dick Tracy. It first appeared in 1942, and it proved so popular that it ran intermittently during the next 35 years. Gould was parodied personally in the series as cartoonist "Lester Gooch"—the diminutive, much-harassed and occasionally deranged "creator" of Fosdick. The style of the Fosdick sequences closely mimicks Tracy, including the urban setting, the outrageous villains, the galloping mortality rate, the crosshatched shadows, and even the lettering style. In 1952, Fosdick was the star of his own short-lived puppet show on NBC, featuring the Mary Chase marionettes. Besides Dick Tracy, Capp parodied many other comic strips in Li'l Abner—including Steve Canyon, Superman (at least twice; first as "Jack Jawbreaker" in 1947, and again in 1966 as "Chickensouperman"), Mary Worth as "Mary Worm", Peanuts {with "Peewee" a parody of Charlie Brown with "Croopy" parody of Snoopy" {1968} drawn by Bedley Damp a parody of Charles Schulz}, Rex Morgan, M.D., Little Annie Rooney, and Little Orphan Annie (in which Punjab became "Punjbag," an oleaginous slob). Fearless Fosdick—and Capp's other spoofs such as "Little Fanny Gooney" (1952) and "Jack Jawbreaker"—were almost certainly an early inspiration for Harvey Kurtzman's Mad Magazine, which began in 1952 as a comic book that specifically parodied other comics in the same distinctive style and subversive manner. Capp also lampooned popular recording idols of the day, such as Elvis Presley ("Hawg McCall", 1957), Liberace ("Loverboynik", 1956), the Beatles ("the Beasties", 1964)—and in 1944, Frank Sinatra. "Sinatra was the first great public figure I ever wrote about," Capp once said. "I called him 'Hal Fascinatra.' I remember my news syndicate was so worried about what his reaction might be, and we were all surprised when he telephoned and told me how thrilled he was with it. He always made it a point to send me champagne whenever he happened to see me in a restaurant..." (from Frank Sinatra, My Father by Nancy Sinatra, 1985). On the other hand, Liberace was "cut to the quick" over Loverboynik, according to Capp, and even threatened legal action—as would Joan Baez later, over "Joanie Phoanie" in 1967. Capp was just as likely to parody himself; his self-caricature made frequent, tongue-in-cheek appearances in Li'l Abner. The gag was often at his own expense, as in the above 1951 sequence showing Capp's interaction with "fans" (see excerpt), or in his 1955 Disneyland parody, "Hal Yappland". Just about anything could be a target for Capp's satire—in one storyline Li'l Abner is revealed to be the missing link between ape and man. In another, the search is on in Dogpatch for a pair of missing socks knitted by the first president of the United States. In addition to creating Li'l Abner, Capp also co-created two other newspaper strips: Abbie an' Slats with magazine illustrator Raeburn van Buren in 1937, and Long Sam with cartoonist Bob Lubbers in 1954, as well as the Sunday "topper" strips Washable Jones, Small Fry (a.k.a. Small Change), and Advice fo' Chillun. Critical recognition According to comics historian Coulton Waugh, a 1947 poll of newspaper readers who claimed they ignored the comics page altogether revealed that many confessed to making a single exception: Li'l Abner. "When Li'l Abner made its debut in 1934, the vast majority of comic strips were designed chiefly to amuse or thrill their readers. Capp turned that world upside-down by routinely injecting politics and social commentary into Li'l Abner. The strip was the first to regularly introduce characters and story lines having nothing to do with the nominal stars of the strip. The technique—as invigorating as it was unorthodox—was later adopted by cartoonists such as Walt Kelly [Pogo] and Garry Trudeau [Doonesbury]", wrote comic strip historian Rick Marschall. According to Marschall, Li'l Abner gradually evolved into a broad satire of human nature. In his book America's Great Comic Strip Artists (1989), Marschall's analysis revealed a decidedly misanthropic subtext. Over the years, Li'l Abner has been adapted to radio, animated cartoons, stage production, motion pictures, and television. Capp has been compared, at various times, to Mark Twain, Dostoevski, Jonathan Swift, Lawrence Sterne, and Rabelais. Fans of the strip ranged from novelist John Steinbeck—who called Capp "possibly the best writer in the world today" in 1953 and even earnestly recommended him for the Nobel Prize in literature—to media critic and theorist Marshall McLuhan, who considered Capp "the only robust satirical force in American life". John Updike, comparing Abner to a "hillbilly Candide", added that the strip's "richness of social and philosophical commentary approached the Voltairean". Charlie Chaplin, William F. Buckley, Al Hirschfeld, Harpo Marx, Russ Meyer, John Kenneth Galbraith, Ralph Bakshi, Shel Silverstein, Hugh Downs, Gene Shalit, Frank Cho, Daniel Clowes, and (reportedly) even Queen Elizabeth have confessed to being fans of Li'l Abner. Li'l Abner was also the subject of the first book-length scholarly assessment of an American comic strip ever published. Li'l Abner: A Study in American Satire by Arthur Asa Berger (Twayne, 1969) contained serious analyses of Capp's narrative technique, his use of dialogue, self-caricature, and grotesquerie, the place of Li'l Abner in American satire, and the significance of social criticism and the graphic image. "One of the few strips ever taken seriously by students of American culture," wrote Professor Berger, "Li'l Abner is worth studying ... because of Capp's imagination and artistry, and because of the strip's very obvious social relevance." It was reprinted by the University Press of Mississippi in 1994. The 1940s and 1950s During World War II and for many years afterward, Capp worked tirelessly going to hospitals to entertain patients, especially to cheer recent amputees and explain to them that the loss of a limb did not mean an end to a happy and productive life. Making no secret of his own disability, Capp openly joked about his prosthetic leg his whole life. In 1946, Capp created a special full-color comic book, Al Capp by Li'l Abner, to be distributed by the Red Cross to encourage the thousands of amputee veterans returning from the war. Capp also was involved with the Sister Kenny Foundation, which pioneered new treatments for polio in the 1940s. Serving in his capacity as honorary chairman, Capp made public appearances on its behalf for years, contributed free artwork for its annual fundraising appeals, and entertained disabled and paraplegic children in children's hospitals with inspirational pep talks, humorous stories, and sketches. In 1940, an RKO movie adaptation starred Granville Owen (later known as Jeff York) as Li'l Abner, with Buster Keaton taking the role of Lonesome Polecat, and featuring a title song with lyrics by Milton Berle. A successful musical comedy adaptation of the strip opened on Broadway at the St. James Theater on November 15, 1956, and had a long run of 693 performances, followed by a nationwide tour. The stage musical, with music and lyrics by Gene de Paul and Johnny Mercer, was adapted into a Technicolor motion picture at Paramount in 1959 by producer Norman Panama and director Melvin Frank, with a score by Nelson Riddle. Several performers repeated their Broadway roles in the film, most memorably Julie Newmar as Stupefyin' Jones and Stubby Kaye as Marryin' Sam. Other highlights of that decade included the 1942 debut of Fearless Fosdick as Abner's "ideel" (hero); the 1946 Lena the Hyena Contest, in which a hideous Lower Slobbovian gal was ultimately revealed in the harrowing winning entry (as judged by Frank Sinatra, Boris Karloff, and Salvador Dalí) drawn by noted cartoonist Basil Wolverton; and an ill-fated Sunday parody of Gone With the Wind that aroused anger and legal threats from author Margaret Mitchell, and led to a printed apology within the strip. In October 1947, Li'l Abner met Rockwell P. Squeezeblood, head of the abusive and corrupt Squeezeblood Comic Strip Syndicate. The resulting sequence, "Jack Jawbreaker Fights Crime!", was a devastating satire of Jerry Siegel and Joe Shuster's notorious exploitation by DC Comics over Superman. It was later reprinted in The World of Li'l Abner (1953). (Siegel and Shuster had earlier poked fun at Capp in a Superman story in Action Comics #55, December 1942, in which a cartoonist named "Al Hatt" invents a comic strip featuring the hillbilly "Tiny Rufe".) In 1947, Capp earned a Newsweek cover story. That same year the New Yorker's profile on him was so long that it ran in consecutive issues. In 1948, Capp reached a creative peak with the introduction of the Shmoos, lovable and innocent fantasy creatures who reproduced at amazing speed and brought so many benefits that, ironically, the world economy was endangered. The much-copied storyline was a parable that was metaphorically interpreted in many different ways at the outset of the Cold War. Following his close friend Milton Caniff's lead (with Steve Canyon), Capp had recently fought a successful battle with the syndicate to gain complete ownership of his feature when the Shmoos debuted. As a result, he reaped enormous financial rewards from the unexpected (and almost unprecedented) merchandising phenomenon that followed. As in the strip, Shmoos suddenly appeared to be everywhere in 1949 and 1950—including a Time cover story. A paperback collection of the original sequence, The Life and Times of the Shmoo, became a bestseller for Simon & Schuster. Shmoo dolls, clocks, watches, jewelry, earmuffs, wallpaper, fishing lures, air fresheners, soap, ice cream, balloons, ashtrays, comic books, records, sheet music, toys, games, Halloween masks, salt and pepper shakers, decals, pinbacks, tumblers, coin banks, greeting cards, planters, neckties, suspenders, belts, curtains, fountain pens, and other Shmoo paraphernalia were produced. A garment factory in Baltimore turned out a whole line of Shmoo apparel, including "Shmooveralls". The original sequence and its 1959 sequel The Return of the Shmoo have been collected in print many times since, most recently in 2011, always to high sales figures. The Shmoos later had their own animated television series. Capp followed this success with other allegorical fantasy critters, including the aboriginal and masochistic "Kigmies", who craved abuse (a story that began as a veiled comment on racial and religious oppression), the dreaded "Nogoodniks" (or bad shmoos), and the irresistible "Bald Iggle", a guileless creature whose sad-eyed countenance compelled involuntary truthfulness—with predictably disastrous results. Li'l Abner was censored for the first time, but not the last, in September 1947 and was pulled from papers by Scripps-Howard. The controversy, as reported in Time, centered on Capp's portrayal of the United States Senate. Edward Leech of Scripps said, "We don't think it is good editing or sound citizenship to picture the Senate as an assemblage of freaks and crooks ... boobs and undesirables." Capp criticized Senator Joseph McCarthy in 1954, calling him a "poet". "He uses poetic license to try to create the beautifully ordered world of good guys and bad guys that he wants," said Capp. "He seems at his best when terrifying the helpless and naïve." Capp received the National Cartoonists Society's Billy DeBeck Memorial Award in 1947 for Cartoonist of the Year. (When the award name was changed in 1954, Capp also retroactively received a Reuben statuette.) He was an outspoken pioneer in favor of diversifying the NCS by admitting women cartoonists. Originally, the Society had disallowed female members. Capp briefly resigned his membership in 1949 to protest their refusal of admission to Hilda Terry, creator of the comic strip Teena. According to Tom Roberts, author of Alex Raymond: His Life and Art (2007), Capp delivered a stirring speech that was instrumental in changing those rules. The NCS finally accepted female members the following year. In December 1952, Capp published an article in Real magazine entitled "The REAL Powers in America" that further challenged the conventional attitudes of the day: "The real powers in America are women—the wives and sweethearts behind the masculine dummies...." Highlights of the 1950s included the much-heralded marriage of Abner and Daisy Mae in 1952, the birth of their son "Honest Abe" Yokum in 1953, and in 1954 the introduction of Abner's enormous, long-lost kid brother Tiny Yokum, who filled Abner's place as a bachelor in the annual Sadie Hawkins Day race. In 1952, Capp and his characters graced the covers of both Life and TV Guide. The year 1956 saw the debut of Bald Iggle, considered by some Abner enthusiasts to be the creative high point of the strip, as well as Mammy's revelatory encounter with the "Square Eyes" Family—Capp's thinly-veiled appeal for racial tolerance. (This fable-like story was collected into an educational comic book called Mammy Yokum and the Great Dogpatch Mystery! and distributed by the Anti-Defamation League of B'nai B'rith later that year.) Two years later, Capp's studio issued Martin Luther King and the Montgomery Story, a biographical comic book distributed by the Fellowship of Reconciliation. Often, Capp had parodied corporate greed—pork tycoon J. Roaringham Fatback had figured prominently in wiping out the Shmoos. But in 1952, when General Motors president Charles E. Wilson, nominated for a cabinet post, told Congress "...what was good for the country was good for General Motors and vice versa", he inspired one of Capp's greatest satires—the introduction of General Bullmoose, the robust, ruthless, and ageless business tycoon. The blustering Bullmoose, who seemed to own and control nearly everything, justified his far-reaching and mercenary excesses by saying "What's good for General Bullmoose is good for the USA!" Bullmoose's corrupt interests were often pitted against those of the pathetic Lower Slobbovians in a classic mismatch of "haves" versus "have-nots". This character, along with the Shmoos, helped cement Capp's favor with the Left, and increased their outrage a decade later when Capp, a former Franklin D. Roosevelt liberal, switched targets. Nonetheless, General Bullmoose continued to appear, undaunted and unredeemed, during the strip's final right-wing phase and into the 1970s. Feud with Ham Fisher After Capp quit his ghosting job on Ham Fisher's Joe Palooka in 1934 to launch his own strip, Fisher badmouthed him to colleagues and editors, claiming that Capp had "stolen" his idea. For years, Fisher brought the characters back to his strip, billing them as "The ORIGINAL Hillbilly Characters" and advising readers not to be "fooled by imitations". (In fact, Fisher's brutish hillbilly character—Big Leviticus, created by Capp in Fisher's absence—bore little resemblance to Li'l Abner.) According to a November 1950 Time article, "Capp parted from Fisher with a definite impression, (to put it mildly) that he had been underpaid and unappreciated. Fisher, a man of Roman self esteem, considered Capp an ingrate and a whippersnapper, and watched his rise to fame with unfeigned horror." "Fisher repeatedly brought Leviticus and his clan back, claiming their primacy as comics' first hillbilly family – but he was missing the point. It wasn't the setting that made Capp's strip such a huge success. It was Capp's finely tuned sense of the absurd, his ability to milk an outrageous situation for every laugh in it and then, impossibly, to squeeze even more laughs from it, that found such favor with the public," (from Don Markstein's Toonopedia). The Capp-Fisher feud was well known in cartooning circles, and it grew more personal as Capp's strip eclipsed Joe Palooka in popularity. Fisher hired away Capp's top assistant, Moe Leff. After Fisher underwent plastic surgery, Capp included a racehorse in Li'l Abner named "Ham's Nose-Bob". In 1950, Capp introduced a cartoonist character named "Happy Vermin"—a caricature of Fisher—who hired Abner to draw his comic strip in a dimly lit closet (after sacking his previous "temporary" assistant of 20 years, who had been cut off from all his friends in the process). Instead of using Vermin's tired characters, Abner inventively peopled the strip with hillbillies. A bighearted Vermin told his slaving assistant: "I'm proud of having created these characters!! They'll make millions for me!! And if they do – I'll get you a new light bulb!!" Traveling in the same social circles, the two men engaged in a 20-year mutual vendetta, as described by the New York Daily News in 1998: "They crossed paths often, in the midtown watering holes and at National Cartoonists Society banquets, and the city's gossip columns were full of their snarling public donnybrooks." In 1950, Capp wrote a nasty article for The Atlantic, entitled "I Remember Monster". The article recounted Capp's days working for an unnamed "benefactor" with a miserly, swinish personality, who Capp claimed was a never-ending source of inspiration when it came time to create a new unregenerate villain for his comic strip. The thinly-veiled boss was understood to be Ham Fisher. Fisher retaliated, doctoring photostats of Li'l Abner and falsely accusing Capp of sneaking obscenities into his comic strip. Fisher submitted examples of Li'l Abner to Capp's syndicate and to the New York courts, in which Fisher had identified pornographic images that were hidden in the background art. However, the X-rated material had been drawn there by Fisher. Capp was able to refute the accusation by simply showing the original artwork. In 1954, when Capp was applying for a Boston television license, the Federal Communications Commission (FCC) received an anonymous packet of pornographic Li'l Abner drawings. The National Cartoonists Society (NCS) convened an ethics hearing, and Fisher was expelled for the forgery from the same organization that he had helped found; Fisher's scheme had backfired in spectacular fashion. Around the same time, his mansion in Wisconsin was destroyed by a storm. On December 27, 1955, Fisher committed suicide in his studio. The feud and Fisher's suicide were used as the basis for a lurid, highly fictionalized murder mystery, Strip for Murder by Max Allan Collins. Another "feud" seemed to be looming when, in one run of Sunday strips in 1957, Capp lampooned the comic strip Mary Worth as "Mary Worm". The title character was depicted as a nosy, interfering busybody. Allen Saunders, the creator of the Mary Worth strip, returned Capp's fire with the introduction of the character "Hal Rapp", a foul-tempered, ill-mannered, and (ironically) inebriated cartoonist, (Capp was a teetotaler). Later, the "feud" was revealed to be a collaborative hoax that Capp and his longtime pal Saunders had cooked up together. The Capp-Saunders "feud" fooled both editors and readers, generated plenty of free publicity for both strips—and Capp and Saunders had a good laugh when all was revealed. Personality Capp, Milton Caniff (Terry and the Pirates, Steve Canyon) and Walt Kelly (Pogo) were close personal friends and professional associates throughout their adult lives, and occasionally, referenced each other in their strips. According to one anecdote (from Al Capp Remembered, 1994), Capp and his brother Elliot ducked out of a dull party at Capp's home—leaving Walt Kelly alone to fend for himself entertaining a group of Argentine envoys who didn't speak English. Kelly retaliated by giving away Capp's baby grand piano. According to Capp, who loved to relate the story, Kelly's two perfectly logical reasons for doing so were: a. to cement diplomatic relations between Argentina and the United States, and b. "Because you can't play the piano, anyway!" (Beetle Bailey creator Mort Walker confirmed the story, relating a slightly expanded version in his autobiography, Mort Walker's Private Scrapbook, 2001.) Milton Caniff offered another anecdote (from Phi Beta Pogo, 1989) involving Capp and Walt Kelly, "two boys from Bridgeport, Connecticut, nose to nose," onstage at a meeting of the Newspaper Comics Council in the sixties. "Walt would say to Al, 'Of course, Al, this is really how you should draw Daisy Mae, I'm only showing you this for your own good.' Then Walt would do a sketch. Capp, of course, got ticked off by this, as you can imagine! So he retaliated by doing his version of Pogo. Unfortunately, the drawings are long gone; no recording was made. What a shame! Nobody anticipated there'd be this dueling back and forth between the two of them ..." Although he was often considered a difficult person, some acquaintances of Capp have stressed that the cartoonist also had a sensitive side. In 1973, upon learning that 12-year-old Ted Kennedy Jr., the son of his political rival Ted Kennedy Sr., had his right leg amputated, Capp wrote the boy an encouraging letter that gave candid advice about dealing with the loss of a limb, which Capp himself had experienced as a boy. One of Capp's grandchildren recalls that at one point, tears were streaming down the cartoonist's cheeks while he was watching a documentary about the Jonestown massacre. Capp gave money anonymously to charities and "people in need" at various points in his life. Sexual harassment and assault claims In her autobiography, American actress Goldie Hawn stated that Capp sexually propositioned her on a casting couch and exposed himself to her when she was 19 years old. When she refused his advances, Capp became angry and told her that she was "never gonna make anything in your life" and that she should "go and marry a Jewish dentist. You'll never get anywhere in this business." Two biographies, one about Goldie Hawn and the other about Grace Kelly, describe Capp as trying to force Kelly into having sex with him, and he later tried to do the same with Hawn. In 1971, investigative journalist Jack Anderson wrote that Capp had exposed his genitals to four female students at the University of Alabama. In 1972, after an incident at the University of Wisconsin–Eau Claire, Capp was arrested. He pleaded guilty to a charge of attempted adultery, while charges of indecent exposure and sodomy were dropped. He was fined US$500 (). In 2019, Jean Kilbourne was inspired by the MeToo movement to publish in Hogan's Alley her own experience of being groped and sexually solicited by Al Capp while doing freelance writing and research work for him in contemplation of a permanent job in 1967. Production methods Like many cartoonists, Capp made extensive use of assistants (notably Andy Amato, Harvey Curtis, Walter Johnson, and Frank Frazetta). During the extended peak of the strip, the workload grew to include advertising, merchandising, promotional work, public service comics, and other specialty work—in addition to the regular six dailies and one Sunday strip per week. From the early 1940s to the late 1950s, there were scores of Sunday strip-style magazine ads for Cream of Wheat using the Abner characters, and in the 1950s, Fearless Fosdick became a spokesman for Wildroot Cream-Oil hair tonic in a series of daily strip-style print ads. The characters also sold chainsaws, underwear, ties, detergent, candy, soft drinks—including a licensed version of Capp's moonshine creation, Kickapoo Joy Juice—and General Electric and Procter & Gamble products, all requiring special artwork. No matter how much help he had, Capp insisted on his drawing and inking the characters' faces and hands—especially of Abner and Daisy Mae—and his distinctive touch is often discernible. "He had the touch," Frazetta said of Capp in 2008. "He knew how to take an otherwise ordinary drawing and really make it pop. I'll never knock his talent." As is usual with collaborative efforts in comic strips, his name was the only one credited— although, sensitive to his own experience working on Joe Palooka, Capp frequently drew attention to his assistants in interviews and publicity pieces. A 1950 cover story in Time even included photographs of two of his employees, whose roles in the production were detailed by Capp. Ironically, this highly irregular policy (along with the subsequent fame of Frank Frazetta) has led to the misconception that his strip was "ghosted" by other hands. The production of Li'l Abner has been well documented, however. In point of fact, Capp maintained creative control over every stage of production for virtually the entire run of the strip. Capp originated the stories, wrote the dialogue, designed the major characters, rough penciled the preliminary staging and action of each panel, oversaw the finished pencils, and drew and inked the hands and faces of the characters. Frazetta authority David Winiewicz described the everyday working mode of operation in Li'l Abner Dailies: 1954 Volume 20 (Kitchen Sink, 1994): There was also a separate line of comic book titles published by the Caplin family-owned Toby Press, including Shmoo Comics featuring Washable Jones. Cartoonist Mell Lazarus, creator of Miss Peach and Momma, wrote a comic novel in 1963 entitled The Boss Is Crazy, Too which was partly inspired by his apprenticeship days working with Capp and his brother Elliot at Toby. In a seminar at the Charles Schulz Museum on November 8, 2008, Lazarus called his experience at Toby "the five funniest years of my life". Lazarus went on to cite Capp as one of the "four essentials" in the field of newspaper cartoonists, along with Walt Kelly, Charles Schulz, and Milton Caniff. Capp detailed his approach to writing and drawing the stories in an instructional course book for the Famous Artists School, beginning in 1956. In 1959, Capp recorded and released an album for Folkways Records (now owned by the Smithsonian) on which he identified and described "The Mechanics of the Comic Strip". Frazetta, later famous as a fantasy artist, assisted on the strip from 1954 to December 1961. Fascinated by Frazetta's abilities, Capp initially gave him a free hand in an extended daily sequence (about a biker named "Frankie," a caricature of Frazetta) to experiment with the basic look of the strip by adding a bit more realism and detail (particularly to the inking). After editors complained about the stylistic changes, the strip's previous look was restored. During most of his tenure with Capp, Frazetta's primary responsibility—along with various specialty art, such as a series of Li'l Abner greeting cards—was tight-penciling the Sunday pages from studio roughs. This work was collected by Dark Horse Comics in a four-volume hardcover series entitled Al Capp's Li'l Abner: The Frazetta Years. In 1961, Capp, complaining of declining revenue, wanted to have Frazetta continue with a 50% pay cut. "[Capp] said he would cut the salary in half. Goodbye. That was that. I said goodbye," (from Frazetta: Painting with Fire). However, Frazetta returned briefly a few years later to draw a public service comic book called Li'l Abner and the Creatures from Drop-Outer Space, distributed by the Job Corps in 1965. Public service works Capp provided specialty artwork for civic groups, government agencies, and charitable or nonprofit organizations, spanning several decades. The following titles are all single-issue, educational comic books and pamphlets produced for various public services: Al Capp by Li'l Abner— Public service giveaway issued by the Red Cross (1946) Yo' Bets Yo' Life!— Public service giveaway issued by the U.S. Army () Li'l Abner Joins the Navy— Public service giveaway issued by the Dept. of the Navy (1950) Fearless Fosdick and the Case of the Red Feather— Public service giveaway issued by Red Feather Services, a forerunner of United Way (1951) The Youth You Supervise— Public service giveaway issued by the U.S. Department of Labor (1956) Mammy Yokum and the Great Dogpatch Mystery!— Public service giveaway issued by the Anti-Defamation League of B'nai B'rith (1956) Operation: Survival!— Public service giveaway issued by the Dept. of Civil Defense (1957) Natural Disasters!— Public service giveaway issued by the Department of Civil Defense (1957) Martin Luther King and the Montgomery Story— Public service giveaway issued by The Fellowship of Reconciliation (1958) Li'l Abner and the Creatures from Drop-Outer Space— Public service giveaway issued by the Job Corps (1965) In addition, Dogpatch characters were used in national campaigns for the U.S. Treasury, the Cancer Foundation, the March of Dimes, the National Heart Fund, the Sister Kenny Foundation, the Boy Scouts of America, Community Chest, the National Reading Council, Minnesota Tuberculosis and Health Association, Christmas Seals, the National Amputation Foundation, and Disabled American Veterans, among others. Public figure In the Golden Age of the American comic strip, successful cartoonists received a great deal of attention; their professional and private lives were reported in the press, and their celebrity was often nearly sufficient to rival their creations. As Li'l Abner reached its peak years, and following the success of the Shmoos and other high moments in his work, Al Capp achieved a public profile that is still unparalleled in his profession, and arguably exceeded the fame of his strip. "Capp was the best known, most influential and most controversial cartoonist of his era," writes publisher (and leading Shmoo collector) Denis Kitchen. "His personal celebrity transcended comics, reaching the public and influencing the culture in a variety of media. For many years he simultaneously produced the daily strip, a weekly syndicated newspaper column, and a 500-station radio program..." He ran the Boston Summer Theatre with The Phantom cartoonist Lee Falk, bringing in Hollywood actors such as Mae West, Melvyn Douglas, and Claude Rains to star in their live productions. He even briefly considered running for a Massachusetts Senate seat. Vice President Spiro Agnew urged Capp to run in the Democratic Party Massachusetts primary in 1970 against Ted Kennedy, but Capp ultimately declined. (He did, however, donate his services as a speaker at a $100-a-plate fundraiser for Republican Congressman Jack Kemp.) Besides his use of the comic strip to voice his opinions and display his humor, Capp was a popular guest speaker at universities, and on radio and television. He remains the only cartoonist to be embraced by television; no other comic artist to date has come close to Capp's televised exposure. Capp appeared as a regular on The Author Meets the Critics (1948–'54) and made regular, weekly appearances on Today in 1953. He was also a periodic panelist on ABC and NBC's Who Said That? (1948–'55), and co-hosted DuMont's What's the Story? (1953). Between 1952 and 1972, he hosted at least five television shows–three different talk shows called The Al Capp Show (1952 and 1968) and Al Capp (1971–'72), Al Capp's America (a live "chalk talk," with Capp providing a barbed commentary while sketching cartoons, 1954), and a CBS game show called Anyone Can Win (1953). He also hosted similar vehicles on the radio—and was a familiar celebrity guest on various other broadcast programs, including NBC Radio's long-running Monitor with its famous Monitor Beacon audio signature, as a commentator dubbed "An expert of nothing with opinions on everything." His frequent appearances on NBC's The Tonight Show spanned three emcees (Steve Allen, Jack Paar, and Johnny Carson), from the 1950s to the 1970s. One memorable story, as recounted to Johnny Carson, was about his meeting with then-President Dwight D. Eisenhower. As Capp was ushered into the Oval Office, his prosthetic leg suddenly collapsed into a pile of disengaged parts and hinges on the floor. The President immediately turned to an aide and said, "Call Walter Reed (Hospital), or maybe Bethesda," to which Capp replied, "Hell no, just call a good local mechanic!" (Capp also spoofed Carson in his strip, in a 1970 episode called "The Tommy Wholesome Show".) Capp portrayed himself in a cameo role in the Bob Hope film That Certain Feeling, for which he also provided promotional art. He was interviewed live on Person to Person on November 27, 1959, by host Charles Collingwood. He also appeared as himself on The Ed Sullivan Show, Sid Caesar's Your Show of Shows, The Red Skelton Show, The Merv Griffin Show, The Mike Douglas Show, and guested on Ralph Edwards' This Is Your Life on February 12, 1961, with honoree Peter Palmer. Capp also freelanced very successfully as a magazine writer and newspaper columnist, in a wide variety of publications including Life, Show, Pageant, The Atlantic, Esquire, Coronet, and The Saturday Evening Post. Capp was impersonated by comedians Rich Little and David Frye. Although Capp's endorsement activities never rivaled Li'l Abner's or Fearless Fosdick's, he was a celebrity spokesman in print ads for Sheaffer Snorkel fountain pens (along with colleagues and close friends Milton Caniff and Walt Kelly), and—with an irony that became apparent later—a brand of cigarettes (Chesterfield). Capp resumed visiting war amputees during the Korean War and Vietnam War. He toured Vietnam with the USO, entertaining troops along with Art Buchwald and George Plimpton. He served as chairman of the Cartoonists' Committee in President Dwight D. Eisenhower's People-to-People program in 1954 (although Capp had supported Adlai Stevenson for president in 1952 and 1956), which was organized to promote Savings bonds for the U.S. Treasury. Capp had earlier provided the Shmoo for a special Children's Savings Bond in 1949, accompanying President Harry S. Truman at the bond's unveiling ceremony. During the Soviet Union's blockade of West Berlin in 1948, the commanders of the Berlin airlift had cabled Capp, requesting inflatable shmoos as part of "Operation: Little Vittles". Candy-filled shmoos were air-dropped to hungry West Berliners by America's 17th Military Airport Squadron during the humanitarian effort. "When the candy-chocked shmoos were dropped, a near-riot resulted," (reported in Newsweek—October 11, 1948). In addition to his public service work for charitable organizations for disabled people, Capp also served on the National Reading Council, which was organized to combat illiteracy. He published a column ("Wrong Turn Onto Sesame Street") challenging federally funded public television endowments in favor of educational comics—which, according to Capp, "didn't cost a dime in taxes and never had. I pointed out that a kid could enjoy Sesame Street without learning how to read, but he couldn't enjoy comic strips unless he could read; and that a smaller investment in getting kids to read by supplying them with educational matter in such reading form might make better sense." Capp's academic interests included being one of nineteen original "Trustees and Advisors" for "Endicott, Junior College for Young Woman", located in Pride's Crossing (Beverly), Massachusetts, which was founded in 1939. Al Capp is listed in the 1942 Mingotide Yearbook, representing the first graduating class from what is now the 4-year school known as Endicott College. The yearbook entry includes his credential as a "Cartoonist for United Feature Syndicate" and a resident of New York City. "Comics," wrote Capp in 1970, "can be a combination of the highest quality of art and text, and many of them are." Capp produced many giveaway educational comic books and public services pamphlets, spanning several decades, for the Red Cross, the Department of Civil Defense, the Department of the Navy, the U.S. Army, the Anti-Defamation League, the Department of Labor, Community Chest (a forerunner of United Way), and the Job Corps. Capp's studio provided special artwork for various civic groups and nonprofit organizations as well. Dogpatch characters were used in national campaigns for the Cancer Foundation, the March of Dimes, the National Heart Fund, the Boy Scouts of America, Minnesota Tuberculosis and Health Association, the National Amputation Foundation, and Disabled American Veterans, among others. They were also used to help sell Christmas Seals. In the early 1960s, Capp regularly wrote a column entitled Al Capp's Column for the newspaper The Schenectady Gazette (currently The Daily Gazette). He was the Playboy interview subject in December 1965, in a conversation conducted by Alvin Toffler. In August 1967, Capp was the narrator and host of an ABC network special called Do Blondes Have More Fun? In 1970, he was the subject of a provocative NBC documentary called This Is Al Capp. The 1960s and 1970s Capp and his family lived in Cambridge, Massachusetts, near Harvard during the entire Vietnam War protest era. The turmoil that Americans were watching on their television sets was happening live—right in his own neighborhood. Campus radicals and "hippies" inevitably became one of Capp's favorite targets in the sixties. Alongside his long-established caricatures of right-wing, big business types such as General Bullmoose and J. Roaringham Fatback, Capp began spoofing counterculture icons such as Joan Baez (in the character of Joanie Phoanie, a wealthy folksinger who offers an impoverished orphanage ten thousand dollars' worth of "protest songs"). The sequence implicitly labeled Baez a limousine liberal, a charge she took to heart, as detailed years later in her 1987 autobiography, And A Voice To Sing With: A Memoir. Another target was Senator Ted Kennedy, parodied as "Senator O. Noble McGesture", resident of "Hyideelsport". The town name is a play on Hyannisport, Massachusetts, where a number of the Kennedy clan have lived. Capp became a popular public speaker on college campuses, where he reportedly relished hecklers. He attacked militant antiwar demonstrators, both in his personal appearances and in his strip. He also satirized student political groups. The Youth International Party (YIP) and Students for a Democratic Society (SDS) emerged in Li'l Abner as "Students Wildly Indignant about Nearly Everything!" (SWINE). In an April 1969 letter to Time, Capp insisted, "The students I blast are not the dissenters, but the destroyers—the less than 4% who lock up deans in washrooms, who burn manuscripts of unpublished books, who make combination pigpens and playpens of their universities. The remaining 96% detest them as heartily as I do." Capp's increasingly controversial remarks at his campus speeches and during television appearances cost him his semi-regular spot on the Tonight Show. His contentious public persona during this period was captured on a late sixties comedy LP called Al Capp On Campus. The album features his interaction with students at Fresno State College (now California State University, Fresno) on such topics as "sensitivity training," "humanitarianism," "abstract art" (Capp hated it), and "student protest". The cover features a cartoon drawing by Capp of wildly dressed, angry hippies carrying protest signs with slogans like "End Capp Brutality", "Abner and Daisy Mae Smoke Pot", "Capp Is Over [30, 40, 50—all crossed out] the Hill!!", and "If You Like Crap, You'll Like Capp!" Highlights of the strip's final decades include "Boomchik" (1961), in which America's international prestige is saved by Mammy Yokum, "Daisy Mae Steps Out" (1966), a female-empowering tale of Daisy's brazenly audacious "homewrecker gland", "The Lips of Marcia Perkins" (1967), a satirical, thinly-veiled commentary on venereal disease and public health warnings, "Ignoble Savages" (1968), in which the Mob takes over Harvard, and "Corporal Crock" (1973), in which Bullmoose reveals his reactionary cartoon role model, in a tale of obsession and the fanatical world of comic book collecting. The cartoonist visited John Lennon and Yoko Ono at their 1969 Bed-In for Peace in Montreal, and their testy exchange later appeared in the documentary film Imagine: John Lennon (1988). Introducing himself with the words "I'm a dreadful Neanderthal fascist. How do you do?", Capp sardonically congratulated Lennon and Ono on their Two Virgins nude album cover: "I think that everybody owes it to the world to prove they have pubic hair. You've done it, and I tell you that I applaud you for it." Following this exchange, Capp insulted Ono ("Good God, you've gotta live with that?"), and was asked to "get out" by Lennon publicist Derek Taylor. Lennon allowed him to stay, however, but the conversation had soured considerably. On Capp's exit, Lennon sang an impromptu version of his song "The Ballad of John and Yoko" with a slightly revised, but nonetheless prophetic lyric: "Christ, you know it ain't easy / You know how hard it can be / The way things are goin' / They're gonna crucify Capp! " Despite his political conservatism in the last decade of his life, Capp is reported to have been liberal in some particular causes; he supported gay rights, and did not tolerate any attempts at homophobic jokes. He is also said to have supported Martin Luther King Jr. and the fight for racial equality in American society, although he was very sceptical of the tactics of the Black Panthers and Malcolm X. In 1968, a theme park called Dogpatch USA opened at Marble Falls, Arkansas, based on Capp's work and with his support. The park was a popular attraction during the 1970s, but was abandoned in 1993 due to financial difficulties. By 2005, the area once devoted to a live-action facsimile of Dogpatch (including a lifesize statue in the town square of Dogpatch "founder" General Jubilation T. Cornpone) had been heavily stripped by vandals and souvenir hunters, and was slowly being reclaimed by the surrounding Arkansas wilderness. On April 22, 1971, syndicated columnist Jack Anderson reported allegations that in February 1968 Capp had made indecent advances to four female students when he was invited to speak at the University of Alabama. Anderson and an associate confirmed that Capp was shown out of town by university police, but that the incident had been hushed up by the university to avoid negative publicity. The following month, Capp was charged in Eau Claire, Wisconsin, in connection with another alleged incident following his April 1 lecture at the University of Wisconsin-Eau Claire. Capp was accused of propositioning a married woman in his hotel room. Although no sexual act was alleged to have resulted, the original charge included "sodomy". As part of a plea agreement, Capp pleaded guilty to the charge of "attempted adultery" (adultery was a felony in Wisconsin) and the other charges were dropped. Capp was fined $500 and court costs. In a December 1992 article for The New Yorker, Seymour Hersh reported that President Richard Nixon and Charles Colson had repeatedly discussed the Capp case in Oval Office recordings that had recently been made available by the National Archives. Nixon and Capp were on friendly terms, Hersh wrote, and Nixon and Colson had worked to find a way for Capp to run against Ted Kennedy for the U.S. Senate. "Nixon was worried about the allegations, fearing that Capp's very close links to the White House would become embarrassingly public", Hersh wrote. "The White House tapes and documents show that he and Colson discussed the issue repeatedly, and that Colson eventually reassured the president by saying that he had, in essence, fixed the case. Specifically, the president was told that one of Colson's people had gone to Wisconsin and tried to talk to the prosecutors." Colson's efforts failed, however. The Eau Claire district attorney, a Republican, refused to dismiss the attempted adultery charge. In passing sentence in February 1972, the judge rejected the D.A.'s motion that Capp agree to undergo psychiatric treatment. The resulting publicity led to hundreds of papers dropping his comic strip, and Capp, already in failing health, withdrew from public speaking. Celebrity biographer James Spada has claimed that similar allegations were made by actress Grace Kelly. However, no firsthand allegation has ever surfaced. "From beginning to end, Capp was acid-tongued toward the targets of his wit, intolerant of hypocrisy, and always wickedly funny. After about 40 years, however, Capp's interest in Abner waned, and this showed in the strip itself," according to Don Markstein's Toonopedia. On November 13, 1977, Capp retired with an apology to his fans for the recently declining quality of the strip, which he said had been the best he could manage due to declining health. "If you have any sense of humor about your strip—and I had a sense of humor about mine—you knew that for three or four years Abner was wrong. Oh hell, it's like a fighter retiring. I stayed on longer than I should have," he admitted, adding that he couldn't breathe anymore. "When he retired Li'l Abner, newspapers ran expansive articles and television commentators talked about the passing of an era. People magazine ran a substantial feature, and even the comics-free New York Times devoted nearly a full page to the event", wrote publisher Denis Kitchen. Capp's final years were marked by advancing illness and by family tragedy. In October 1977, one of his two daughters died; a few weeks later, a beloved granddaughter was killed in a car accident. A lifelong chain smoker, Capp died in 1979 from emphysema at his home in South Hampton, New Hampshire. Capp is buried in Mount Prospect Cemetery in Amesbury, Massachusetts. Engraved on his headstone is a stanza from Thomas Gray: The plowman homeward plods his weary way / And leaves the world to darkness and to me (from Elegy Written in a Country Churchyard, 1751). Legacy "Neither the strip's shifting political leanings nor the slide of its final few years had any bearing on its status as a classic; and in 1995, it was recognized as such by the U.S. Postal Service", according to Toonopedia. Li'l Abner was one of 20 American comic strips included in the Comic Strip Classics series of USPS commemorative stamps. Al Capp, an inductee into the National Cartoon Museum (formerly the International Museum of Cartoon Art), is one of only 31 artists selected to their Hall of Fame. Capp was also inducted into the Will Eisner Award Hall of Fame in 2004. Sadie Hawkins Day and double whammy are two terms attributed to Al Capp that have entered the English language. Other, less ubiquitous Cappisms include skunk works and Lower Slobbovia. The term shmoo also has entered the lexicon, defining highly technical concepts in no fewer than four separate fields of science, including the variations shmooing (a microbiological term for the "budding" process in yeast reproduction), and shmoo plot (a technical term in the field of electrical engineering). In socioeconomics, a "shmoo" refers to any generic kind of good that reproduces itself, (as opposed to "widgets" which require resources and active production). In the field of particle physics, "shmoo" refers to a high energy survey instrument, as used at the Los Alamos National Laboratory to capture subatomic cosmic ray particles emitted from the Cygnus X-3 constellation. Capp also had a knack for popularizing certain uncommon terms, such as druthers, schmooze, and nogoodnik, neatnik, etc. In his book The American Language, H.L. Mencken credits the postwar mania for adding "-nik" to the ends of adjectives to create nouns as beginning—not with beatnik or Sputnik—but earlier, in the pages of Li'l Abner. Al Capp's life and career are the subjects of a new life-sized mural commemorating the 100th anniversary of his birth. Created by resident artist Jon P. Mooers, the mural was unveiled in downtown Amesbury on May 15, 2010. According to the Boston Globe (as reported on May 18, 2010), the town has renamed its amphitheater in the artist's honor, and is looking to develop an Al Capp Museum. Capp is also the subject of an upcoming WNET-TV American Masters documentary, The Life and Times of Al Capp, produced by his granddaughter, independent filmmaker Caitlin Manning. Since his death in 1979, Al Capp and his work have been the subject of more than 40 books, including three biographies. Underground cartoonist and Li'l Abner expert Denis Kitchen has published, co-published, edited, or otherwise served as consultant on nearly all of them. Kitchen is currently compiling a biographical monograph on Al Capp. At the San Diego Comic Con in July 2009, IDW announced the upcoming publication of Al Capp's Li'l Abner: The Complete Dailies and Color Sundays as part of their ongoing The Library of American Comics series. The comprehensive series, a reprinting of the entire 43-year history of Li'l Abner, spanning a projected 20 volumes, began on April 7, 2010.

Alexey Pajitnov

Alexey Leonidovich Pajitnov (born April 16, 1955) is a Russian computer engineer and video game designer who is best known for creating, designing, and developing Tetris in 1985 while working at the Dorodnitsyn Computing Centre under the Academy of Sciences of the Soviet Union (now the Russian Academy of Sciences). In 1991, he moved to the United States and later became a U.S. citizen. In 1996, Pajitnov founded The Tetris Company alongside Dutch video game designer Henk Rogers. Pajitnov did not receive royalties from Tetris prior to this time, despite the game's high popularity. Early life Pajitnov was born to parents who were both writers. His father was an art critic. His mother was a journalist who wrote for both newspapers and a film magazine. It was through his parents that Pajitnov gained exposure to the arts, eventually developing a passion for cinema. He accompanied his mother to many film screenings, including the Moscow Film Festival. Pajitnov was also mathematically inclined, enjoying puzzles and problem solving. In 1967, when he was 11 years old, Pajitnov's parents divorced. For several years, he lived with his mother in a one-bedroom apartment owned by the state. The two were eventually able to move into a private apartment at 49 Gertsen Street, when Pajitnov was 17. He later went on to study applied mathematics at the Moscow Aviation Institute. Career In 1977, Pajitnov worked as a summer intern at the Soviet Academy of Sciences. Once he graduated in 1979, he accepted a job there working on speech recognition at the Academy's Dorodnitsyn Computing Centre. When the Computing Centre received new equipment, its researchers would write a small program for it in order to test its computing capabilities. According to Pajitnov, this "became [his] excuse for making games". Computer games were fascinating to him because they offered a way to bridge the gap between logic and emotion, and Pajitnov held interests in both mathematics and puzzles, as well as the psychology of computing. Searching for inspiration, Pajitnov recalled his childhood memories of playing pentominoes, a game in which the user creates pictures using its shapes. Remembering the difficulty he had in putting the pieces back into their box, Pajitnov felt inspired to create a game based on that concept. Using an Electronika 60 in the Computing Centre, he began working on what would become the first version of Tetris. Building the first prototype in two weeks, Pajitnov spent longer playtesting and adding to the game, completing it on June 6, 1985. This primitive version did not have levels or a scoring system, but Pajitnov knew he had a potentially great game, since he could not stop playing it at work. The game attracted the interest of coworkers like fellow programmer Dmitri Pevlovsky, who helped Pajitnov connect with Vadim Gerasimov, a 16-year-old intern at the Soviet Academy. Pajitnov wanted to make a color version of Tetris for the IBM Personal Computer, and enlisted the intern to help. Gerasimov created the PC version in less than three weeks, and with contributions from Pevlovsky, spent an additional month adding new features like scorekeeping and sound effects. The game, first available in the Soviet Union, appeared in the West in 1986. Pajitnov created a sequel to Tetris, entitled Welltris, which has the same principle, but in a three-dimensional environment where the player sees the playing area from above. Tetris was licensed and managed by Soviet company ELORG, which had a monopoly on the import and export of computer hardware and software in the Soviet Union, and advertised with the slogan "From Russia with Love" (on NES: "From Russia with Fun!"). Because he was employed by the Soviet government, Pajitnov did not receive royalties. Pajitnov, together with Vladimir Pokhilko, moved to the United States following the collapse of the Soviet Union in 1991, and in 1996 founded The Tetris Company with Henk Rogers, which finally allowed him to collect royalties from his game. He helped design the puzzles in the Super NES versions of Yoshi's Cookie and designed the game Pandora's Box, which incorporates more traditional jigsaw-style puzzles. Pajitnov and Pokhilko founded the 3D software technology company AnimaTek, which developed the game / screensaver El-Fish. He was employed by Microsoft from October 1996 until 2005. While there, he worked on the Microsoft Entertainment Pack: The Puzzle Collection, MSN Mind Aerobics and MSN Games groups. Pajitnov's new, enhanced version of Hexic, Hexic HD, was included with every new Xbox 360 Premium package. In August 2005, WildSnake Software announced that Pajitnov would be collaborating with them to release a new line of puzzle games. Personal life Pajitnov moved to the United States in 1991, was naturalized as a U.S. citizen and now lives in Clyde Hill, Washington. He has a wife, Nina, with whom he had two sons named Artem and Dmitri. Political views After the Russian invasion of Ukraine in 2022, Pajitnov issued a statement condemning the war and stating that he was "sure that Putin and his hateful regime will fall down and the normal peaceful way of living will be restored in Ukraine and, hopefully, in Russia." Games Awards and recognition In 1996, GameSpot named him as the fourth most influential computer game developer of all time. In March 2007, he received the Game Developers Choice Awards First Penguin Award. The award was given for pioneering the casual games market. In June 2009, he received the honorary award at the LARA - Der Deutsche Games Award in Cologne, Germany. In 2012, IGN included Pajitnov on their list of 5 Memorable Video Game Industry One-Hit Wonders, calling him "the ultimate video game one-hit wonder." In 2015, Pajitnov won the Bizkaia Award at the Fun & Serious Game Festival. Pajitnov was portrayed by Russian actor Nikita Yefremov in the 2023 movie Tetris, a dramatised retelling of the licensing bidding war for Tetris in the late 1980s.

ʻAbdu'l-Bahá

ʻAbdu'l-Bahá (; Persian: ‎, 23 May 1844 – 28 November 1921), born ʻAbbás (), was the eldest son of Baháʼu'lláh and served as head of the Baháʼí Faith from 1892 until 1921. ʻAbdu'l-Bahá was later canonized as the last of three "central figures" of the religion, along with Baháʼu'lláh and the Báb, and his writings and authenticated talks are regarded as sources of Baháʼí sacred literature. He was born in Tehran to an aristocratic family. At the age of eight his father was imprisoned during a government crackdown on the Bábí Faith and the family's possessions were looted, leaving them in virtual poverty. His father was exiled from their native Iran, and the family went to live in Baghdad, where they stayed for nine years. They were later called by the Ottoman state to Istanbul before going into another period of confinement in Edirne and finally the prison-city of ʻAkká (Acre). ʻAbdu'l-Bahá remained a political prisoner there until the Young Turk Revolution freed him in 1908 at the age of 64. He then made several journeys to the West to spread the Baháʼí message beyond its middle-eastern roots, but the onset of World War I left him largely confined to Haifa from 1914 to 1918. The war replaced the openly hostile Ottoman authorities with the British Mandate, who appointed him a Knight Commander of the Order of the British Empire for his help in averting famine following the war. In 1892, ʻAbdu'l-Bahá was appointed in his father's will to be his successor and head of the Baháʼí Faith. He faced opposition from virtually all his family members, but held the loyalty of the great majority of Baháʼís around the world. His Tablets of the Divine Plan helped galvanize Baháʼís in North America into spreading the Baháʼí teachings to new territories, and his Will and Testament laid the foundation for the current Baháʼí administrative order. Many of his writings, prayers and letters are extant, and his discourses with the Western Baháʼís emphasize the growth of the religion by the late 1890s. ʻAbdu'l-Bahá's given name was ʻAbbás. Depending on context, he would have gone by either Mírzá ʻAbbás (Persian) or ʻAbbás Effendi (Turkish), both of which are equivalent to the English Sir ʻAbbás. He preferred the title of ʻAbdu'l-Bahá ("servant of Bahá", a reference to his father). He is commonly referred to in Baháʼí texts as "The Master". Early life ʻAbdu'l-Bahá was born in Tehran, Persia (now Iran) on 23 May 1844 (5th of Jamadiyu'l-Avval, 1260 AH), the eldest son of Baháʼu'lláh and Navváb. He was born on the very same night on which the Báb declared his mission. Born with the given name of ʻAbbás, he was named after his grandfather Mírzá ʻAbbás Núrí, a prominent and powerful nobleman. As a child, ʻAbdu'l-Bahá was shaped by his father's position as a prominent Bábí. He recalled how he met the Bábí Táhirih and how she would take "me on to her knee, caress me, and talk to me. I admired her most deeply". ʻAbdu'l-Bahá had a happy and carefree childhood. The family's Tehran home and country houses were comfortable and beautifully decorated. ʻAbdu'l-Bahá enjoyed playing in the gardens with his younger sister with whom he was very close. Along with his younger siblings – a sister, Bahíyyih, and a brother, Mihdí – the three lived in an environment of privilege, happiness and comfort. During his young childhood ʻAbdu'l-Bahá witnessed his parents' various charitable endeavours, which included converting part of the home to a hospital ward for women and children. With most of his life was spent in exile and prison, there was little chance for normal schooling. Even when younger, it was customary not to send children of nobility to schools. Most noblemen were educated at home briefly in scripture, rhetoric, calligraphy and basic mathematics. Many were educated to prepare themselves for life in the royal court. Despite a brief spell at a traditional preparatory school at the age of seven for one year, ʻAbdu'l-Bahá received no formal education. As he grew he was educated by his mother, and uncle. Most of his education however, came from his father. Years later in 1890 Edward Granville Browne described how ʻAbdu'l-Bahá was "one more eloquent of speech, more ready of argument, more apt of illustration, more intimately acquainted with the sacred books of the Jews, the Christians, and the Muhammadans...scarcely be found even amongst the eloquent." According to contemporary accounts, ʻAbdu'l-Bahá was an eloquent and charming child. When ʻAbdu'l-Bahá was seven, he contracted tuberculosis and was expected to die. Though the malady faded away, he would be plagued with bouts of illness for the rest of his life. One event that affected ʻAbdu'l-Bahá greatly during his childhood was the imprisonment of his father when ʻAbdu'l-Bahá was eight years old; the imprisonment led to his family being reduced to poverty and being attacked in the streets by other children. ʻAbdu'l-Bahá accompanied his mother to visit Baháʼu'lláh who was then imprisoned in the infamous subterranean dungeon the Síyáh-Chál. He described how "I saw a dark, steep place. We entered a small, narrow doorway, and went down two steps, but beyond those one could see nothing. In the middle of the stairway, all of a sudden we heard His [Baháʼu'lláh's]…voice: 'Do not bring him in here', and so they took me back". Baghdad Baháʼu'lláh was eventually released from prison, but ordered into exile, and ʻAbdu'l-Bahá, then eight years old, joined his father on the journey to Baghdad in the winter (January to April) of 1853. During the journey ʻAbdu'l-Bahá suffered from frost-bite. After a year of difficulties Baháʼu'lláh absented himself rather than continue to face the conflict with Mirza Yahya and secretly secluded himself in the mountains of Sulaymaniyah in April 1854 a month before ʻAbdu'l-Bahá's tenth birthday. Mutual sorrow resulted in him, his mother and sister becoming constant companions. ʻAbdu'l-Bahá was particularly close to both, and his mother took active participation in his education and upbringing. During the two-year absence of his father ʻAbdu'l-Bahá took up the duty of managing the affairs of the family, before his age of maturity (14 in middle-eastern society) and was known to be occupied with reading and, at a time of hand-copied scriptures being the primary means of publishing, was also engaged in copying the writings of the Báb. ʻAbdu'l-Bahá also took an interest in the art of horse riding and, as he grew, became a renowned rider. In 1856, news of an ascetic carrying on discourses with local Súfí leaders that seemed to possibly be Baháʼu'lláh reached the family and friends. Immediately, family members and friends went to search for the elusive dervish – and in March brought Baháʼu'lláh back to Baghdad. On seeing his father, ʻAbdu'l-Bahá fell to his knees and wept loudly "Why did you leave us?", and this followed with his mother and sister doing the same. ʻAbdu'l-Bahá soon became his father's secretary and shield. During the sojourn in the city ʻAbdu'l-Bahá grew from a boy into a young man. He was noted as a "remarkably fine looking youth", and remembered for his charity. Having passed the age of maturity ʻAbdu'l-Bahá was regularly seen in the mosques of Baghdad discussing religious topics and the scripture as a young man. Whilst in Baghdad, ʻAbdu'l-Bahá composed a commentary at the request of his father on the Muslim tradition of "I was a Hidden Treasure" for a Súfí leader named ʻAlí Shawkat Páshá. ʻAbdu'l-Bahá was fifteen or sixteen at the time and ʻAlí Shawkat Páshá regarded the more than 11,000-word essay as a remarkable feat for somebody of his age. In 1863, in what became known as the Garden of Ridván, his father Baháʼu'lláh announced to a few that he was the manifestation of God and He whom God shall make manifest whose coming had been foretold by the Báb. On day eight of the twelve days, it is believed ʻAbdu'l-Bahá was the first person Baháʼu'lláh revealed his claim to. Istanbul/Adrianople In 1863, Baháʼu'lláh was summoned to Istanbul, and thus his family, including ʻAbdu'l-Bahá, then eighteen, accompanied him on his 110-day journey. The journey to Constantinople was another wearisome journey, and ʻAbdu'l-Bahá helped feed the exiles. It was here that his position became more prominent amongst the Baháʼís. This was further solidified by Baháʼu'lláh's tablet of the Branch in which he constantly exalts his son's virtues and station. The family were soon exiled to Adrianople and ʻAbdu'l-Bahá went with the family. ʻAbdu'l-Bahá again suffered from frostbite. In Adrianople ʻAbdu'l-Bahá was regarded as the sole comforter of his family – in particular to his mother. At this point ʻAbdu'l-Bahá was known by the Baháʼís as "the Master", and by non-Baháʼís as ʻAbbás Effendi ("Effendi" signifies "Sir"). It was in Adrianople that Baháʼu'lláh referred to his son as "the Mystery of God". The title of "Mystery of God" symbolises, according to Baháʼís, that ʻAbdu'l-Bahá is not a manifestation of God but how a "person of ʻAbdu'l-Bahá the incompatible characteristics of a human nature and superhuman knowledge and perfection have been blended and are completely harmonized". Baháʼu'lláh gave his son many other titles such as G͟husn-i-Aʻzam (meaning "Mightiest Branch" or "Mightier Branch"), the "Branch of Holiness", "the Center of the Covenant" and the apple of his eye. ʻAbdu'l-Bahá ("the Master") was devastated when hearing the news that he and his family were to be exiled separately from Baháʼu'lláh. It was, according to Baháʼís, through his intercession that the idea was reverted and the family were allowed to be exiled together. ʻAkká At the age of 24, ʻAbdu'l-Bahá was clearly chief-steward to his father and an outstanding member of the Baháʼí community. Baháʼu'lláh and his family were – in 1868 – exiled to the penal colony of Acre, Palestine where it was expected that the family would perish. Arrival in ʻAkká was distressing for the family and exiles. They were greeted in a hostile manner by the surrounding population and his sister and father fell dangerously ill. When told that the women were to sit on the shoulders of the men to reach the shore, ʻAbdu'l-Bahá took a chair and carried the women to the bay of ʻAkká. ʻAbdu'l-Bahá was able to procure some anesthetic and nursed the sick. The Baháʼís were imprisoned under horrendous conditions in a cluster of cells covered in excrement and dirt. ʻAbdu'l-Bahá himself fell dangerously ill with dysentery, however a sympathetic soldier permitted a physician to help cure him. The population shunned them, the soldiers treated them the same, and the behaviour of Siyyid Muhammad-i-Isfahani (an Azali) did not help matters. Morale was further destroyed with the accidental death of ʻAbdu'l-Bahá's youngest brother Mírzá Mihdí at the age of 22. The grieving ʻAbdu'l-Bahá kept a night-long vigil beside his brother's body. Later in ʻAkká Over time, he gradually took over responsibility for the relationships between the small Baháʼí exile community and the outside world. It was through his interaction with the people of ʻAkká (Acre) that, according to the Baháʼís, they recognized the innocence of the Baháʼís, and thus the conditions of imprisonment were eased. Four months after the death of Mihdí the family moved from the prison to the House of ʻAbbúd. The people of ʻAkká started to respect the Baháʼís and in particular, ʻAbdu'l-Bahá. ʻAbdu'l-Bahá was able to arrange for houses to be rented for the family, the family later moved to the Mansion of Bahjí around 1879 when an epidemic caused the inhabitants to flee. ʻAbdu'l-Bahá soon became very popular in the penal colony and Myron Henry Phelps a wealthy New York lawyer described how "a crowd of human beings...Syrians, Arabs, Ethiopians, and many others", all waited to talk and receive ʻAbdu'l-Bahá. He undertook a history of the Bábí religion through publication of A Traveller's Narrative (Makála-i-Shakhsí Sayyáh) in 1886, later translated and published in translation in 1891 through Cambridge University by the agency of Edward Granville Browne. Marriage and family life When ʻAbdu'l-Bahá was a young man, speculation was rife amongst the Baháʼís to whom he would marry. Several young girls were seen as marriage prospects but ʻAbdu'l-Bahá seemed disinclined to marriage. On 8 March 1873, at the urging of his father, the twenty-eight-year-old ʻAbdu'l-Bahá married Fátimih Nahrí of Isfahán (1847–1938) a twenty-five-year-old from an upper-class family of the city. Her father was Mírzá Muḥammad ʻAlí Nahrí of Isfahan an eminent Baháʼí with prominent connections. Fátimih was brought from Persia to ʻAkká after both Baháʼu'lláh and his wife Navváb expressed an interest in her to marry ʻAbdu'l-Bahá. After a wearisome journey from Isfahán to Akka she finally arrived accompanied by her brother in 1872. The young couple were betrothed for about five months before the marriage itself commenced. In the meantime, Fátimih lived in the home of ʻAbdu'l-Bahá's uncle Mírzá Músá. According to her later memoirs, Fátimih fell in love with ʻAbdu'l-Bahá on seeing him. ʻAbdu'l-Bahá himself had showed little inkling to marriage until meeting Fátimih; who was entitled Munírih by Baháʼu'lláh. Munírih is a title meaning "Luminous". The marriage resulted in nine children. The first born was a son Mihdí Effendi who died aged about 3. He was followed by Ḍíyáʼíyyih K͟hánum, Fuʼádíyyih K͟hánum (d. few years old), Rúhangíz Khánum (d. 1893), Túbá Khánum, Husayn Effendi (d.1887 aged 5), Túbá K͟hánum, Rúhá K͟hánum (mother of Munib Shahid), and Munnavar K͟hánum. The death of his children caused ʻAbdu'l-Bahá immense grief – in particular the death of his son Husayn Effendi came at a difficult time following the death of his mother and uncle. The surviving children (all daughters) were; Ḍíyáʼíyyih K͟hánum (mother of Shoghi Effendi) (d. 1951) Túbá K͟hánum (1880–1959) Rúḥá K͟hánum and Munavvar K͟hánum (d. 1971). Baháʼu'lláh wished that the Baháʼís follow the example of ʻAbdu'l-Bahá and gradually move away from polygamy. The marriage of ʻAbdu'l-Bahá to one woman and his choice to remain monogamous, from advice of his father and his own wish, legitimised the practice of monogamy to a people who hitherto had regarded polygamy as a righteous way of life. Early years of his ministry After Baháʼu'lláh died on 29 May 1892, the Will and Testament of Baháʼu'lláh named ʻAbdu'l-Bahá as Centre of the Covenant, successor and interpreter of Baháʼu'lláh's writings. Baháʼu'lláh designates his successor with the following verses: This translation of the Kitáb-i-ʻAhd is based on a solecism, however, as the terms Akbar and Aʻzam do not mean, respectively, 'Greater' and 'Most Great'. Not only do the two words derive from entirely separate triconsonantal roots (Akbar from k-b-r and Aʻzam from ʻ-z-m), but the Arabic language possesses the elative, a stage of gradation, with no clear distinction between the comparative and superlative. In the Will and Testament ʻAbdu'l-Bahá's half-brother, Muhammad ʻAlí, was mentioned by name as being subordinate to ʻAbdu'l-Bahá. Muhammad ʻAlí became jealous of his half-brother and set out to establish authority for himself as an alternative leader with the support of his brothers Badiʻu'llah and Ḍíyáʼu'llah. He began correspondence with Baháʼís in Iran, initially in secret, casting doubts in others' minds about ʻAbdu'l-Bahá. While most Baháʼís followed ʻAbdu'l-Bahá, a handful followed Muhammad ʻAlí including such leaders as Mirza Javad and Ibrahim George Kheiralla, an early Baháʼí missionary to America. Muhammad ʻAlí and Mirza Javad began to openly accuse ʻAbdu'l-Bahá of taking on too much authority, suggesting that he believed himself to be a Manifestation of God, equal in status to Baháʼu'lláh. It was at this time that ʻAbdu'l-Bahá, to provide proof of the falsity of the accusations leveled against him, in tablets to the West, stated that he was to be known as "ʻAbdu'l-Bahá" an Arabic phrase meaning the Servant of Bahá to make it clear that he was not a Manifestation of God, and that his station was only servitude. ʻAbdu'l-Bahá left a Will and Testament that set up the framework of administration. The two highest institutions were the Universal House of Justice, and the Guardianship, for which he appointed Shoghi Effendi as the Guardian. With the exception of ʻAbdu'l-Bahá and Shoghi Effendi, Muhammad ʻAlí was supported by all of the remaining male relatives of Baháʼu'lláh, including Shoghi Effendi's father, Mírzá Hádí Shírází. However Muhammad ʻAlí's and his families statements had very little effect on the Baháʼís in general – in the ʻAkká area, the followers of Muhammad ʻAlí represented six families at most, they had no common religious activities, and were almost wholly assimilated into Muslim society. First Western pilgrims By the end of 1898, Western pilgrims started coming to Akka on pilgrimage to visit ʻAbdu'l-Bahá; this group of pilgrims, including Phoebe Hearst, was the first time that Baháʼís raised up in the West had met ʻAbdu'l-Bahá. The first group arrived in 1898 and throughout late 1898 to early 1899 Western Baháʼís sporadically visited ʻAbdu'l-Bahá. The group was relatively young containing mainly women from high American society in their 20s. The group of Westerners aroused suspicion for the authorities, and consequently ʻAbdu'l-Bahá's confinement was tightened. During the next decade ʻAbdu'l-Bahá would be in constant communication with Baháʼís around the world, helping them to teach the religion; the group included May Ellis Bolles in Paris, Englishman Thomas Breakwell, American Herbert Hopper, French , Susan Moody, Lua Getsinger, and American Laura Clifford Barney. It was Laura Clifford Barney who, by asking questions of ʻAbdu'l-Bahá over many years and many visits to Haifa, compiled what later became the book Some Answered Questions. Ministry, 1901–1912 During the final years of the 19th century, while ʻAbdu'l-Bahá was still officially a prisoner and confined to ʻAkka, he organized the transfer of the remains of the Báb from Iran to Palestine. He then organized the purchase of land on Mount Carmel that Baháʼu'lláh had instructed should be used to lay the remains of the Báb, and organized for the construction of the Shrine of the Báb. This process took another 10 years. With the increase of pilgrims visiting ʻAbdu'l-Bahá, Muhammad ʻAlí worked with the Ottoman authorities to re-introduce stricter terms on ʻAbdu'l-Bahá's imprisonment in August 1901. By 1902, however, due to the Governor of ʻAkka being supportive of ʻAbdu'l-Bahá, the situation was greatly eased; while pilgrims were able to once again visit ʻAbdu'l-Bahá, he was confined to the city. In February 1903, two followers of Muhammad ʻAlí, including Badiʻu'llah and Siyyid ʻAliy-i-Afnan, broke with Muhammad ʻAli and wrote books and letters giving details of Muhammad ʻAli's plots and noting that what was circulating about ʻAbdu'l-Bahá was fabrication. From 1902 to 1904, in addition to the building of the Shrine of the Báb that ʻAbdu'l-Bahá was directing, he started to put into execution two different projects; the restoration of the House of the Báb in Shiraz, Iran and the construction of the first Baháʼí House of Worship in Ashgabat, Turkmenistan. ʻAbdu'l-Bahá asked Aqa Mirza Aqa to coordinate the work so that the house of the Báb would be restored to the state that it was at the time of the Báb's declaration to Mulla Husayn in 1844; he also entrusted the work on the House of Worship to Vakil-u'd-Dawlih. During this period, ʻAbdu'l-Bahá communicated with a number of Young Turks, opposed to the reign of Sultan Abdul Hamid II, including Namık Kemal, Ziya Pasha and Midhat Pasha, in an attempt to disseminate Baháʼí thought into their political ideology. He emphasized Baháʼís "seek freedom and love liberty, hope for equality, are well-wishers of humanity and ready to sacrifice their lives to unite humanity" but on a more broad approach than the Young Turks. Abdullah Cevdet, one of the founders of the Committee of Union and Progress who considered the Baháʼí Faith an intermediary step between Islam and the ultimate abandonment of religious belief, would go on trial for defense of Baháʼís in a periodical he founded. ‛Abdu'l-Bahá also had contact with military leaders as well, including such individuals as Bursalı Mehmet Tahir Bey and Hasan Bedreddin. The latter, who was involved in the overthrow of Sultan Abdülaziz, is commonly known as Bedri Paşa or Bedri Pasha and is referred to in Persian Baháʼí sources as Bedri Bey (Badri Beg). He was a Baháʼí who translated ‛Abdu'l-Baha's works into French. ʻAbdu'l-Bahá also met Muhammad Abduh, one of the key figures of Islamic Modernism and the Salafi movement, in Beirut, at a time when the two men were both opposed to the Ottoman ulama and shared similar goals of religious reform. Rashid Rida asserts that during his visits to Beirut, ʻAbdu'l-Bahá would attend Abduh's study sessions. Regarding the meetings of ʻAbdu'l-Bahá and Muhammad ʻAbduh, Shoghi Effendi asserts that "His several interviews with the well-known Shaykh Muhammad ʻAbdu served to enhance immensely the growing prestige of the community and spread abroad the fame of its most distinguished member." Due to ʻAbdu'l-Bahá's political activities and alleged accusation against him by Muhammad ʻAli, a Commission of Inquiry interviewed ʻAbdu'l-Bahá in 1905, with the result that he was almost exiled to Fezzan. In response, ʻAbdu'l-Bahá wrote the sultan a letter protesting that his followers refrain from involvement in partisan politics and that his tariqa had guided many Americans to Islam. The next few years in ʻAkka were relatively free of pressures and pilgrims were able to come and visit ʻAbdu'l-Bahá. By 1909 the mausoleum of the Shrine of the Báb was completed. Journeys to the West The 1908 Young Turks revolution freed all political prisoners in the Ottoman Empire, and ʻAbdu'l-Bahá was freed from imprisonment. His first action after his freedom was to visit the Shrine of Baháʼu'lláh in Bahji. While ʻAbdu'l-Bahá continued to live in ʻAkka immediately following the revolution, he soon moved to live in Haifa near the Shrine of the Báb. In 1910, with the freedom to leave the country, he embarked on a three-year journey to Egypt, Europe, and North America, spreading the Baháʼí message. From August to December 1911, ʻAbdu'l-Bahá visited cities in Europe, including London, Bristol, and Paris. The purpose of these trips was to support the Baháʼí communities in the west and to further spread his father's teachings. In the following year, he undertook a much more extensive journey to the United States and Canada to once again spread his father's teachings. He arrived in New York City on 11 April 1912, after declining an offer of passage on the RMS Titanic, telling the Baháʼí believers, instead, to "Donate this to charity." He instead travelled on a slower craft, the RMS Cedric, and cited preference of a longer sea journey as the reason. After hearing of the Titanic's sinking on 16 April he was quoted as saying "I was asked to sail upon the Titanic, but my heart did not prompt me to do so." While he spent most of his time in New York, he visited Chicago, Cleveland, Pittsburgh, Washington, D.C., Boston and Philadelphia. In August of the same year he started a more extensive journey to places including New Hampshire, the Green Acre school in Maine, and Montreal (his only visit to Canada). He then travelled west to Minneapolis, San Francisco, Stanford, and Los Angeles before starting to return east at the end of October. On 5 December 1912 he set sail back to Europe. During his visit to North America he visited many missions, churches, and groups, as well as having scores of meetings in Baháʼís' homes, and offering innumerable personal meetings with hundreds of people. During his talks he proclaimed Baháʼí principles such as the unity of God, unity of the religions, oneness of humanity, equality of women and men, world peace and economic justice. He also insisted that all his meetings be open to all races. His visit and talks were the subject of hundreds of newspaper articles. In Boston newspaper reporters asked ʻAbdu'l-Bahá why he had come to America, and he stated that he had come to participate in conferences on peace and that just giving warning messages is not enough. ʻAbdu'l-Bahá's visit to Montreal provided notable newspaper coverage; on the night of his arrival the editor of the Montreal Daily Star met with him and that newspaper along with The Montreal Gazette, Montreal Standard, and among others reported on ʻAbdu'l-Bahá's activities. The headlines in those papers included "Persian Teacher to Preach Peace", "Racialism Wrong, Says Eastern Sage, Strife and War Caused by Religious and National Prejudices", and "Apostle of Peace Meets Socialists, Abdul Baha's Novel Scheme for Distribution of Surplus Wealth." The Montreal Standard, which was distributed across Canada, took so much interest that it republished the articles a week later; the Gazette published six articles and Montreal's largest French language newspaper published two articles about him. His 1912 visit to Montreal also inspired humourist Stephen Leacock to parody him in his bestselling 1914 book Arcadian Adventures with the Idle Rich. In Chicago one newspaper headline included "His Holiness Visits Us, Not Pius X but A. Baha," and ʻAbdu'l-Bahá's visit to California was reported in the Palo Altan. Back in Europe, he visited London, Edinburgh, Paris (where he stayed for two months), Stuttgart, Budapest, and Vienna. Finally, on 12 June 1913, he returned to Egypt, where he stayed for six months before returning to Haifa. On 23 February 1914, at the eve of World War I, ʻAbdu'l-Bahá hosted Baron Edmond James de Rothschild, a member of the Rothschild banking family who was a leading advocate and financier of the Zionist movement, during one of his early trips to Palestine. Final years (1914–1921) During World War I (1914–1918) ʻAbdu'l-Bahá stayed in Palestine and was unable to travel. He carried on a limited correspondence, which included the Tablets of the Divine Plan, a collection of 14 letters addressed to the Baháʼís of North America, later described as one of three "charters" of the Baháʼí Faith. The letters assign a leadership role for the North American Baháʼís in spreading the religion around the planet. Haifa was under real threat of Allied bombardment, enough that ʻAbdu'l-Bahá and other Baháʼís temporarily retreated to the hills east of ʻAkka. ʻAbdu'l-Bahá was also under threats from Cemal Paşa, the Ottoman military chief who at one point expressed his desire to crucify him and destroy Baháʼí properties in Palestine. The swift Megiddo offensive of the British General Allenby swept away the Turkish forces in Palestine before harm was done to the Baháʼís, and the war was over less than two months later. Post-war period The conclusion of World War I led to the openly hostile Ottoman authorities being replaced by the more friendly British Mandate, allowing for a renewal of correspondence, pilgrims, and development of the Baháʼí World Centre properties. It was during this revival of activity that the Baháʼí Faith saw an expansion and consolidation in places like Egypt, the Caucasus, Iran, Turkmenistan, North America and South Asia under the leadership of ʻAbdu'l-Bahá. The end of the war brought about several political developments that ʻAbdu'l-Bahá commented on. The League of Nations formed in January 1920, representing the first instance of collective security through a worldwide organization. ʻAbdu'l-Bahá had written in 1875 for the need to establish a "Union of the nations of the world", and he praised the attempt through the League of Nations as an important step towards the goal. He also said that it was "incapable of establishing Universal Peace" because it did not represent all nations and had only trivial power over its member states. Around the same time, the British Mandate supported the ongoing immigration of Jews to Palestine. ʻAbdu'l-Bahá mentioned the immigration as a fulfillment of prophecy, and encouraged the Zionists to develop the land and "elevate the country for all its inhabitants... They must not work to separate the Jews from the other Palestinians." The war also left the region in famine. In 1901, ʻAbdu'l-Bahá had purchased about 1704 acres of scrubland near the Jordan river and by 1907 many Baháʼís from Iran had begun sharecropping on the land. ʻAbdu'l-Bahá received between 20 and 33% of their harvest (or cash equivalent), which was shipped to Haifa. With the war still raging in 1917, ʻAbdu'l-Bahá received a large amount of wheat from the crops, and also bought other available wheat and shipped it all back to Haifa. The wheat arrived just after the British captured Palestine, and as such was allowed to be widely distributed to allay the famine. For this service in averting a famine in Northern Palestine he received the honour of Knight Commander of the Order of the British Empire at a ceremony held in his honor at the home of the British Governor on 27 April 1920. He was later visited by General Allenby, King Faisal (later King of Iraq), Herbert Samuel (High Commissioner for Palestine), and Ronald Storrs (Military Governor of Jerusalem). Death and funeral ʻAbdu'l-Bahá died on Monday, 28 November 1921, sometime after 1:15 a.m. (27th of Rabi' al-awwal, 1340 AH). Then Colonial Secretary Winston Churchill telegraphed the High Commissioner for Palestine, "convey to the Baháʼí Community, on behalf of His Majesty's Government, their sympathy and condolescence." Similar messages came from Viscount Allenby, the Council of Ministers of Iraq, and others. On his funeral, which was held the next day, Esslemont notes: Among the talks delivered at the funeral, Shoghi Effendi records Stewart Symes giving the following tribute: He was buried in the front room of the Shrine of the Báb on Mount Carmel. His interment there is meant to be temporary, until his own mausoleum can be built in the vicinity of Riḍván Garden, known as the Shrine of ʻAbdu'l-Bahá. Legacy ʻAbdu'l-Bahá left a Will and Testament that was originally written between 1901 and 1908 and addressed to Shoghi Effendi, who at that time was only 4–11 years old. The will appoints Shoghi Effendi as the first in a line of Guardians of the religion, a hereditary executive role that may provide authoritative interpretations of scripture. ʻAbdu'l-Bahá directed all Baháʼís to turn to him and obey him, and assured him of divine protection and guidance. The will also provided a formal reiteration of his teachings, such as the instructions to teach, manifest spiritual qualities, associate with all people, and shun Covenant-breakers. Many obligations of the Universal House of Justice and the Hands of the Cause were also elaborated. Shoghi Effendi later described the document as one of three "charters" of the Baháʼí Faith. The authenticity and provisions of the will were almost universally accepted by Baháʼís around the world, with the exception of Ruth White and a few other Americans who tried to protest Shoghi Effendi's leadership. In volumes of The Baháʼí World published in 1930 and 1933, Shoghi Effendi named nineteen Baháʼís as disciples of ʻAbdu'l-Bahá and heralds of the Covenant, including Thornton Chase, , John Esslemont, Lua Getsinger, and Robert Turner. No other statements about them have been found in Shoghi Effendi's writings. During his lifetime there was some ambiguity among Baháʼís as to his station relative to Baháʼu'lláh, and later to Shoghi Effendi. Some American newspapers reported him to be a Baháʼí prophet or the return of Christ. Shoghi Effendi later formalized his legacy as the last of three "Central Figures" of the Baháʼí Faith and the "Perfect exemplar" of the teachings, also claiming that holding him on an equal status to Baháʼu'lláh or Jesus was heretical. Shoghi Effendi also wrote that during the anticipated Baháʼí dispensation of 1000 years there will be no equal to ʻAbdu'l-Bahá. Appearance and personality ʻAbdu'l-Bahá was described as handsome, and bore striking resemblance to his mother. As an adult he reached medium height but he gave the impression of being taller. He had dark hair that flowed to his shoulders, grey coloured eyes, a fair complexion and an aquiline nose. In 1890, Orientalist Edward Granville Browne met him and wrote: After the death of Bahá’u’lláh, ʻAbdu'l-Bahá began to visibly age. By the late 1890s his hair had turned snow-white and deep lines set on his face. As a young man he was athletic and enjoyed archery, horseback riding and swimming. Even later in his life ʻAbdu'l-Bahá remained active going for long walks in Haifa and Acre. ʻAbdu'l-Bahá was a major presence for the Bahá’ís during his lifetime, and he continues to influence the Bahá’í community today. Bahá’ís regard ‘Abdu’l-Bahá as the perfect example of the teachings of his father and therefore strive to emulate him. Anecdotes about him are frequently used to illustrate particular points about morality and interpersonal relations. He was remembered for his charisma, compassion, philanthropy and strength in the face of suffering. John Esslemont reflected that "[‘Abdu’l-Bahá] showed that it is still possible, amid the whirl and rush of modern life, amid the self-love and struggle for material prosperity that everywhere prevail, to live the life of entire devotion to God and to the service of one's fellows." Even ardent enemies of the Bahá’í Faith were on occasion taken by meeting him. Mírzá 'Abdu'l-Muḥammad Írání Mu'addibu's-Sulṭán, an Iranian, and Shaykh 'Alí Yúsuf, an Arab, were both newspaper editors in Egypt who had published harsh attacks on the Bahá’í Faith in their papers. They called on ‘Abdu’l-Bahá when he was in Egypt and their attitude changed. Similarly, a Christian clergyman, Rev. J.T. Bixby, who was the author of a hostile article on the Bahá’í Faith in the United States, felt compelled to witness Abdu'l-Bahá's personal qualities. The effect of ‘Abdu’l-Bahá on those who were already committed Bahá’ís was greater still. ʻAbdu'l-Bahá was widely known for his encounters with the poor and dying. His generosity resulted in his own family complaining that they were left with nothing. He was sensitive to people’s feelings, and later expressed his wish to be a beloved figure of the Bahá’ís saying “I am your father...and you must be glad and rejoice, for I love you exceedingly.” According to historical accounts, he had a keen sense of humour and was relaxed and informal. He was open about personal tragedies such as the loss of his children and the sufferings he'd endured as a prisoner, further enhancing his popularity. ‘Abdu’l-Bahá directed the affairs of the Bahá’í community with care. He was inclined to allow a large range of personal interpretations of the Bahá’í teachings as long as these did not obviously contradict fundamental principles. He did, however, expel members of the religion he felt were challenging his leadership and deliberately causing disunity in the community. Outbreaks of persecution of the Bahá’ís affected him deeply. He wrote personally to the families of those who had been martyred. Works The total estimated number of tablets that ʻAbdu'l-Bahá wrote are over 27,000 of which only a fraction have been translated into English. His works fall into two groups including first his direct writings and second his lectures and speeches as noted by others. The first group includes The Secret of Divine Civilization written before 1875, A Traveller's Narrative written around 1886, the Resāla-ye sīāsīya or Sermon on the Art of Governance written in 1893, the Memorials of the Faithful, and a large number of tablets written to various people; including various Western intellectuals such as Auguste Forel which has been translated and published as the Tablet to Auguste-Henri Forel. The Secret of Divine Civilization and the Sermon on the Art of Governance were widely circulated anonymously. The second group includes Some Answered Questions, which is an English translation of a series of table talks with Laura Barney, and Paris Talks, ʻAbdu'l-Baha in London and Promulgation of Universal Peace which are respectively addresses given by ʻAbdu'l-Bahá in Paris, London and the United States. The following is a list of some of ʻAbdu'l-Bahá's many books, tablets, and talks: Foundations of World Unity Light of the World: Selected Tablets of ‘Abdu’l-Bahá.

Autonomous building

An autonomous building is a building designed to be operated independently from infrastructural support services such as the electric power grid, gas grid, municipal water systems, sewage treatment systems, storm drains, communication services, and in some cases, public roads. Advocates of autonomous building describe advantages that include reduced environmental impacts, increased security, and lower costs of ownership. Some cited advantages satisfy tenets of green building, not independence per se (see below). Off-grid buildings often rely very little on civil services and are therefore safer and more comfortable during civil disaster or military attacks. For example, Off-grid buildings would not lose power or water if public supplies were compromised. As of 2018, most research and published articles concerning autonomous building focus on residential homes. In 2002, British architects Brenda and Robert Vale said that It is quite possible in all parts of Australia to construct a 'house with no bills', which would be comfortable without heating and cooling, which would make its own electricity, collect its own water and deal with its own waste...These houses can be built now, using off-the-shelf techniques. It is possible to build a "house with no bills" for the same price as a conventional house, but it would be (25%) smaller. History In the 1970s, groups of activists and engineers were inspired by the warnings of imminent resource depletion and starvation. In the United States a group calling themselves the New Alchemists were famous for the depth of research effort placed in their projects. Using conventional construction techniques, they designed a series of "bioshelter" projects, the most famous of which was The Ark bioshelter community for Prince Edward Island. They published the plans for all of these, with detailed design calculations and blueprints. The Ark used wind-based water pumping and electricity and was self-contained in food production. It had living quarters for people, fish tanks raising tilapia for protein, a greenhouse watered with fish water, and a closed-loop sewage reclamation system that recycled human waste into sanitized fertilizer for the fish tanks. As of January 2010, the successor organization to the New Alchemists has a web page up as the "New Alchemy Institute". The PEI Ark has been abandoned and partially renovated several times. The 1990s saw the development of Earthships, similar in intent to the Ark project, but organized as a for-profit venture, with construction details published in a series of 3 books by Mike Reynolds. The building material is tires filled with earth. This makes a wall that has large amounts of thermal mass (see earth sheltering). Berms are placed on exposed surfaces to further increase the house's temperature stability. The water system starts with rain water, processed for drinking, then washing, then plant watering, then toilet flushing, and finally black water is recycled again for more plant watering. The cisterns are placed and used as thermal masses. Power, including electricity, heat and water heating, is from solar power. 1990s architects such as William McDonough and Ken Yeang applied environmentally responsible building design to large commercial buildings, such as office buildings, making them largely self-sufficient in energy production. One major bank building (ING's Amsterdam headquarters) in the Netherlands was constructed to be autonomous and artistic as well. Advantages As an architect or engineer becomes more concerned with the disadvantages of transportation networks, and dependence on distant resources, their designs tend to include more autonomous elements. The historic path to autonomy was a concern for secure sources of heat, power, water and food. A nearly parallel path toward autonomy has been to start with a concern for environmental impacts, which cause disadvantages. Autonomous buildings can increase security and reduce environmental impacts by using on-site resources (such as sunlight and rain) that would otherwise be wasted. Autonomy often dramatically reduces the costs and impacts of networks that serve the building, because autonomy short-circuits the multiplying inefficiencies of collecting and transporting resources. Other impacted resources, such as oil reserves and the retention of the local watershed, can often be cheaply conserved by thoughtful designs. Autonomous buildings are usually energy-efficient in operation, and therefore cost-efficient, for the obvious reason that smaller energy needs are easier to satisfy off-grid. But they may substitute energy production or other techniques to avoid diminishing returns in extreme conservation. An autonomous structure is not always environmentally friendly. The goal of independence from support systems is associated with, but not identical to, other goals of environmentally responsible green building. However, autonomous buildings also usually include some degree of sustainability through the use of renewable energy and other renewable resources, producing no more greenhouse gases than they consume, and other measures. Disadvantages First and fundamentally, independence is a matter of degree. For example, eliminating dependence on the electrical grid is relatively easy. In contrast, running an efficient, reliable food source can be a chore. Living within an autonomous shelter may also require sacrifices in lifestyle or social opportunities. Even the most comfortable and technologically advanced autonomous homes could require alterations of residents' behavior. Some may not welcome the extra chores. The Vails described some clients' experiences as inconvenient, irritating, isolating, or even as an unwanted full-time job. A well-designed building can reduce this issue, but usually at the expense of reduced autonomy. An autonomous house must be custom-built (or extensively retrofitted) to suit the climate and location. Passive solar techniques, alternative toilet and sewage systems, thermal massing designs, basement battery systems, efficient windowing, and the array of other design tactics require some degree of non-standard construction, added expense, ongoing experimentation and maintenance, and also have an effect on the psychology of the space. Systems This section includes some minimal descriptions of methods, to give some feel for such a building's practicality, provide indexes to further information, and give a sense of modern trends. Water There are many methods of collecting and conserving water. Use reduction is cost-effective. Greywater systems reuse drained wash water to flush toilets or to water lawns and gardens. Greywater systems can halve the water use of most residential buildings; however, they require the purchase of a sump, greywater pressurization pump, and secondary plumbing. Some builders are installing waterless urinals and even composting toilets that eliminate water usage in sewage disposal. The classic solution with minimal life-style changes is using a well. Once drilled, a well-foot requires substantial power. However, advanced well-foots can reduce power usage by twofold or more from older models. Well water can be contaminated in some areas. The Sono arsenic filter eliminates unhealthy arsenic in well water. However drilling a well is an uncertain activity, with aquifers depleted in some areas. It can also be expensive. In regions with sufficient rainfall, it is often more economical to design a building to use rainwater harvesting, with supplementary water deliveries in a drought. Rain water makes excellent soft washwater, but needs antibacterial treatment. If used for drinking, mineral supplements or mineralization is necessary. Most desert and temperate climates get at least of rain per year. This means that a typical one-story house with a greywater system can supply its year-round water needs from its roof alone. In the driest areas, it might require a cistern of . Many areas average of rain per week, and these can use a cistern as small as . In many areas, it is difficult to keep a roof clean enough for drinking. To reduce dirt and bad tastes, systems use a metal collecting-roof and a "roof cleaner" tank that diverts the first 40 liters. Cistern water is usually chlorinated, though reverse osmosis systems provide even better quality drinking water. In the classic Roman house ("Domus"), household water was provided from a cistern (the "impluvium"), which was a decorative feature of the atrium, the house's main public space. It was fed by downspout tiles from the inward-facing roof-opening (the "compluvium"). Often water lilies were grown in it to purify the water. Wealthy households often supplemented the rain with a small fountain fed from a city's cistern. The impluvium always had an overflow drain so it could not flood the house. Modern cisterns are usually large plastic tanks. Gravity tanks on short towers are reliable, so pump repairs are less urgent. The least expensive bulk cistern is a fenced pond or pool at ground level. Reducing autonomy reduces the size and expense of cisterns. Many autonomous homes can reduce water use below per person per day, so that in a drought a month of water can be delivered inexpensively via truck. Self-delivery is often possible by installing fabric water tanks that fit the bed of a pick-up truck. It can be convenient to use the cistern as a heat sink or trap for a heat pump or air conditioning system; however this can make cold drinking water warm, and in drier years may decrease the efficiency of the HVAC system. Solar stills can efficiently produce drinking water from ditch water or cistern water, especially high-efficiency multiple effect humidification designs, which separate the evaporator(s) and condenser(s). New technologies, like reverse osmosis can create unlimited amounts of pure water from polluted water, ocean water, and even from humid air. Watermakers are available for yachts that convert seawater and electricity into potable water and brine. Atmospheric water generators extract moisture from dry desert air and filter it to pure water. Sewage Resource Composting toilets use bacteria to decompose human feces into useful, odourless, sanitary compost. The process is sanitary because soil bacteria eat the human pathogens as well as most of the mass of the waste. Nevertheless, most health authorities forbid direct use of "humanure" for growing food. The risk is microbial and viral contamination. In a dry composting toilet, the waste is evaporated or digested to gas (mostly carbon dioxide) and vented, so a toilet produces only a few pounds of compost every six months. To control the odor, modern toilets use a small fan to keep the toilet under negative pressure, and exhaust the gasses to a vent pipe. Some home sewage treatment systems use biological treatment, usually beds of plants and aquaria, that absorb nutrients and bacteria and convert greywater and sewage to clear water. This odor- and color-free reclaimed water can be used to flush toilets and water outside plants. When tested, it approaches standards for potable water. In climates that freeze, the plants and aquaria need to be kept in a small greenhouse space. Good systems need about as much care as a large aquarium. Electric incinerating toilets turn excrement into a small amount of ash. They are cool to the touch, have no water and no pipes, and require an air vent in a wall. They are used in remote areas where use of septic tanks is limited, usually to reduce nutrient loads in lakes. NASA's bioreactor is an extremely advanced biological sewage system. It can turn sewage into air and water through microbial action. NASA plans to use it in the crewed Mars mission. Another method is NASA's urine-to-water distillation system. A big disadvantage of complex biological sewage treatment systems is that if the house is empty, the sewage system biota may starve to death. Waste Sewage handling is essential for public health. Many diseases are transmitted by poorly functioning sewage systems. The standard system is a tiled leach field combined with a septic tank. The basic idea is to provide a small system with primary sewage treatment. Sludge settles to the bottom of the septic tank, is partially reduced by anaerobic digestion, and fluid is dispersed in the leach field. The leach field is usually under a yard growing grass. Septic tanks can operate entirely by gravity, and if well managed, are reasonably safe. Septic tanks have to be pumped periodically by a vacuum truck to eliminate non reducing solids. Failure to pump a septic tank can cause overflow that damages the leach field, and contaminates ground water. Septic tanks may also require some lifestyle changes, such as not using garbage disposals, minimizing fluids flushed into the tank, and minimizing non-digestible solids flushed into the tank. For example, septic safe toilet paper is recommended. However, septic tanks remain popular because they permit standard plumbing fixtures, and require few or no lifestyle sacrifices. Composting or packaging toilets make it economical and sanitary to throw away sewage as part of the normal garbage collection service. They also reduce water use by half, and eliminate the difficulty and expense of septic tanks. However, they require the local landfill to use sanitary practices. Incinerator systems are quite practical. The ashes are biologically safe, and less than 1/10 the volume of the original waste, but like all incinerator waste, are usually classified as hazardous waste. Traditional methods of sewage handling include pit toilets, latrines, and outhouses. These can be safe, inexpensive and practical. They are still used in many regions. Storm drains Drainage systems are a crucial compromise between human habitability and a secure, sustainable watershed. Paved areas and lawns or turf do not allow much precipitation to filter through the ground to recharge aquifers. They can cause flooding and damage in neighbourhoods, as the water flows over the surface towards a low point. Typically, elaborate, capital-intensive storm sewer networks are engineered to deal with stormwater. In some cities, such as the Victorian era London sewers or much of the old City of Toronto, the storm water system is combined with the sanitary sewer system. In the event of heavy precipitation, the load on the sewage treatment plant at the end of the pipe becomes too great to handle and raw sewage is dumped into holding tanks, and sometimes into surface water. Autonomous buildings can address precipitation in a number of ways: If a water-absorbing swale for each yard is combined with permeable concrete streets, storm drains can be omitted from the neighbourhood. This can save more than $800 per house (1970s) by eliminating storm drains. One way to use the savings is to purchase larger lots, which permits more amenities at the same cost. Permeable concrete is an established product in warm climates, and in development for freezing climates. In freezing climates, the elimination of storm drains can often still pay for enough land to construct swales (shallow water collecting ditches) or water impeding berms instead. This plan provides more land for homeowners and can offer more interesting topography for landscaping. A green roof captures precipitation and uses the water to grow plants. It can be built into a new building or used to replace an existing roof. Electricity Since electricity is an expensive utility, the first step towards autonomy is to design a house and lifestyle to reduce demand. LED lights, laptop computers and gas-powered refrigerators save electricity, although gas-powered refrigerators are not very efficient. There are also superefficient electric refrigerators, such as those produced by the Sun Frost company, some of which use only about half as much electricity as a mass-market energy star-rated refrigerator. Using a solar roof, solar cells can provide electric power. Solar roofs can be more cost-effective than retrofitted solar power, because buildings need roofs anyway. Modern solar cells last about 40 years, which makes them a reasonable investment in some areas. At a sufficient angle, solar cells are cleaned by run-off rain water and therefore have almost no life-style impact. However, many areas have long winter nights or dark cloudy days. In these climates, a solar installation might not pay for itself or large battery storage systems are necessary to achieve electric self-sufficiency. In stormy or windy climates, wind generators can replace or significantly supplement solar power. The average autonomous house needs only one small wind turbine, 5 metres or less in diameter. On a 30-metre (100-foot) tower, this turbine can provide enough power to supplement solar power on cloudy days. Commercially available wind turbines use sealed, one-moving-part AC generators and passive, self-feathering blades for years of operation without service. The main advantage of wind power is that larger wind turbines have a lower per-watt cost than solar cells, provided there is wind. However, location is critical. Just as some locations lack sun for solar cells, many areas lack enough wind to make a turbine pay for itself. In the Great Plains of the United States, a 10-metre (33-foot) turbine can supply enough energy to heat and cool a well-built all-electric house. Economic use in other areas requires research, and possibly a site-survey. Some sites have access to a stream with a change in elevation. These sites can use small hydropower systems to generate electricity. If the difference in elevation is above 30 metres (100 feet), and the stream runs in all seasons, this can provide continuous power with a small, inexpensive installation. Lower changes of elevation require larger installations or dams, and can be less efficient. Clogging at the turbine intake can be a practical problem. The usual solution is a small pool and waterfall (a penstock) to carry away floating debris. Another solution is to utilize a turbine that resists debris, such as a Gorlov helical turbine or Ossberger turbine. During times of low demand, excess power can be stored in batteries for future use. However, batteries need to be replaced every few years. In many areas, battery expenses can be eliminated by attaching the building to the electric power grid and operating the power system with net metering. Utility permission is required, but such cooperative generation is legally mandated in some areas (for example, California). A grid-based building is less autonomous, but more economical and sustainable with fewer lifestyle sacrifices. In rural areas the grid's cost and impacts can be reduced by using single-wire earth return systems (for example, the MALT-system). In areas that lack access to the grid, battery size can be reduced with a generator to recharge the batteries during energy droughts such as extended fogs. Auxiliary generators are usually run from propane, natural gas, or sometimes diesel. An hour of charging usually provides a day of operation. Modern residential chargers permit the user to set the charging times, so the generator is quiet at night. Some generators automatically test themselves once per week. Recent advances in passively stable magnetic bearings may someday permit inexpensive storage of power in a flywheel in a vacuum. Research groups like Canada's Ballard Power Systems are also working to develop a "regenerative fuel cell", a device that can generate hydrogen and oxygen when power is available, and combine these efficiently when power is needed. Earth batteries tap electric currents in the earth called telluric current. They can be installed anywhere in the ground. They provide only low voltages and current. They were used to power telegraphs in the 19th century. As appliance efficiencies increase, they may become practical. Microbial fuel cells and thermoelectric generators allow electricity to be generated from biomass. The plant can be dried, chopped and converted or burned as a whole, or it can be left alive so that waste saps from the plant can be converted by bacteria. Heating Most autonomous buildings are designed to use insulation, thermal mass and passive solar heating and cooling. Examples of these are trombe walls and other technologies as skylights. Passive solar heating can heat most buildings in even the mild and chilly climates. In colder climates, extra construction costs can be as little as 15% more than new, conventional buildings. In warm climates, those having less than two weeks of frosty nights per year, there is no cost impact. The basic requirement for passive solar heating is that the solar collectors must face the prevailing sunlight (south in the Northern Hemisphere, north in the Southern Hemisphere), and the building must incorporate thermal mass to keep it warm in the night. A recent, somewhat experimental solar heating system "Annualized geo solar heating" is practical even in regions that get little or no sunlight in winter. It uses the ground beneath a building for thermal mass. Precipitation can carry away the heat, so the ground is shielded with skirts of plastic insulation. The thermal mass of this system is sufficiently inexpensive and large that it can store enough summer heat to warm a building for the whole winter, and enough winter cold to cool the building in summer. In annualized geo solar systems, the solar collector is often separate from (and hotter or colder than) the living space. The building may actually be constructed from insulation, for example, straw-bale construction. Some buildings have been aerodynamically designed so that convection via ducts and interior spaces eliminates any need for electric fans. A more modest "daily solar" design is very practical. For example, for about a 15% premium in building costs, the Passivhaus building codes in Europe use high performance insulating windows, R-30 insulation, HRV ventilation, and a small thermal mass. With modest changes in the building's position, modern krypton- or argon-insulated windows permit normal-looking windows to provide passive solar heat without compromising insulation or structural strength. If a small heater is available for the coldest nights, a slab or basement cistern can inexpensively provide the required thermal mass. Passivhaus building codes, in particular, bring unusually good interior air quality, because the buildings change the air several times per hour, passing it through a heat exchanger to keep heat inside. In all systems, a small supplementary heater increases personal security and reduces lifestyle impacts for a small reduction of autonomy. The two most popular heaters for ultra-high-efficiency houses are a small heat pump, which also provides air conditioning, or a central hydronic (radiator) air heater with water recirculating from the water heater. Passivhaus designs usually integrate the heater with the ventilation system. Earth sheltering and windbreaks can also reduce the absolute amount of heat needed by a building. Several feet below the earth, temperature ranges from in North Dakota to , in Southern Florida. Wind breaks reduce the amount of heat carried away from a building. Rounded, aerodynamic buildings also lose less heat. An increasing number of commercial buildings use a combined cycle with cogeneration to provide heating, often water heating, from the output of a natural gas reciprocating engine, gas turbine or stirling electric generator. Houses designed to cope with interruptions in civil services generally incorporate a wood stove, or heat and power from diesel fuel or bottled gas, regardless of their other heating mechanisms. Electric heaters and electric stoves may provide pollution-free heat (depending on the power source), but use large amounts of electricity. If enough electricity is provided by solar panels, wind turbines, or other means, then electric heaters and stoves become a practical autonomous design. Water heating Hot water heat recycling units recover heat from water drain lines. They increase a building's autonomy by decreasing the heat or fuel used to heat water. They are attractive because they have no lifestyle changes. Current practical, comfortable domestic water-heating systems combine a solar preheating system with a thermostatic gas-powered flow-through heater, so that the temperature of the water is consistent, and the amount is unlimited. This reduces life-style impacts at some cost in autonomy. Solar water heaters can save large amounts of fuel. Also, small changes in lifestyle, such as doing laundry, dishes and bathing on sunny days, can greatly increase their efficiency. Pure solar heaters are especially useful for laundries, swimming pools and external baths, because these can be scheduled for use on sunny days. The basic trick in a solar water heating system is to use a well-insulated holding tank. Some systems are vacuum- insulated, acting something like large thermos bottles. The tank is filled with hot water on sunny days, and made available at all times. Unlike a conventional tank water heater, the tank is filled only when there is sunlight. Good storage makes a smaller, higher-technology collector feasible. Such collectors can use relatively exotic technologies, such as vacuum insulation, and reflective concentration of sunlight. Cogeneration systems produce hot water from waste heat. They usually get the heat from the exhaust of a generator or fuel cell. Heat recycling, cogeneration and solar pre-heating can save 50–75% of the gas otherwise used. Also, some combinations provide redundant reliability by having several sources of heat. Some authorities advocate replacing bottled gas or natural gas with biogas. However, this is usually impractical unless live-stock are on-site. The wastes of a single family are usually insufficient to produce enough methane for anything more than small amounts of cooking. Cooling Annualized geo solar buildings often have buried, sloped water-tight skirts of insulation that extend from the foundations, to prevent heat leakage between the earth used as thermal mass, and the surface. Less dramatic improvements are possible. Windows can be shaded in summer. Eaves can be overhung to provide the necessary shade. These also shade the walls of the house, reducing cooling costs. Another trick is to cool the building's thermal mass at night, perhaps with a whole-house fan and then cool the building from the thermal mass during the day. It helps to be able to route cold air from a sky-facing radiator (perhaps an air heating solar collector with an alternate purpose) or evaporative cooler directly through the thermal mass. On clear nights, even in tropical areas, sky-facing radiators can cool below freezing. If a circular building is aerodynamically smooth, and cooler than the ground, it can be passively cooled by the "dome effect." Many installations have reported that a reflective or light-colored dome induces a local vertical heat-driven vortex that sucks cooler overhead air downward into a dome if the dome is vented properly (a single overhead vent, and peripheral vents). Some people have reported a temperature differential as high as () between the inside of the dome and the outside. Buckminster Fuller discovered this effect with a simple house design adapted from a grain silo, and adapted his Dymaxion house and geodesic domes to use it. Refrigerators and air conditioners operating from the waste heat of a diesel engine exhaust, heater flue or solar collector are entering use. These use the same principles as a gas refrigerator. Normally, the heat from a flue powers an "absorptive chiller". The cold water or brine from the chiller is used to cool air or a refrigerated space. Cogeneration is popular in new commercial buildings. In current cogeneration systems small gas turbines or stirling engines powered from natural gas produce electricity and their exhaust drives an absorptive chiller. A truck trailer refrigerator operating from the waste heat of a tractor's diesel exhaust was demonstrated by NRG Solutions, Inc. NRG developed a hydronic ammonia gas heat exchanger and vaporizer, the two essential new, not commercially available components of a waste heat driven refrigerator. A similar scheme (multiphase cooling) can be by a multistage evaporative cooler. The air is passed through a spray of salt solution to dehumidify it, then through a spray of water solution to cool it, then another salt solution to dehumidify it again. The brine has to be regenerated, and that can be done economically with a low-temperature solar still. Multiphase evaporative coolers can lower the air's temperature by 50 °F (28 °C), and still control humidity. If the brine regenerator uses high heat, they also partially sterilise the air. If enough electric power is available, cooling can be provided by conventional air conditioning using a heat pump. Food production Food production has often been included in historic autonomous projects to provide security. Skilled, intensive gardening can support an adult from as little as 100 square meters of land per person, possibly requiring the use of organic farming and aeroponics. Some proven intensive, low-effort food-production systems include urban gardening (indoors and outdoors). Indoor cultivation may be set up using hydroponics, while outdoor cultivation may be done using permaculture, forest gardening, no-till farming, and do nothing farming. Greenhouses are also sometimes included. Sometimes they are also outfitted with irrigation systems or heat sink-systems which can respectively irrigate the plants or help to store energy from the sun and redistribute it at night (when the greenhouses starts to cool down).

A Funny Thing Happened on the Way to the Forum

A Funny Thing Happened on the Way to the Forum (or A Funny Thing for short) is a musical with music and lyrics by Stephen Sondheim and book by Burt Shevelove and Larry Gelbart. Inspired by the farces of the ancient Roman playwright Plautus (254–184 BC), specifically Curculio, Pseudolus, Miles Gloriosus, and Mostellaria, the musical tells the bawdy story of a slave named Pseudolus and his attempts to win his freedom by helping his young master woo the girl next door. The plot displays many classic elements of farce, including puns, the slamming of doors, cases of mistaken identity (frequently involving characters disguising themselves as one another), and satirical comments on social class. The title derives from a line often used by vaudeville comedians to begin a story: "A funny thing happened on the way to the theater". The musical's original 1962 Broadway run won several Tony Awards, including Best Musical and Best Author (Musical). A Funny Thing has enjoyed several Broadway and West End revivals and was made into a successful film starring the original lead of the stage musical, Zero Mostel. Productions Original Broadway A Funny Thing Happened on the Way to the Forum opened on Broadway on May 8, 1962, at the Alvin Theatre, and then transferred to the Mark Hellinger Theatre and the Majestic Theatre, where the show closed on August 29, 1964, after 964 performances and 8 previews. The show's creators sought Phil Silvers for the lead role of Pseudolus, but he turned them down, allegedly because he would have to perform onstage without his glasses, and his vision was so poor that he feared tripping into the orchestra pit. He is also quoted as turning down the role for being "Sgt. Bilko in a toga". (Silvers eventually played the role – wearing his glasses – in a 1972 revival. In the film, he played Marcus Lycus, without glasses). Milton Berle also passed on the role. Eventually, Zero Mostel was cast. During out-of-town tryouts the show attracted little business and did not play well. Jerome Robbins, to whom the show had originally been offered but who turned it down, was called in to give advice and make changes. In the interim, Joshua Logan was invited to direct, but according to Sondheim was rejected "because he wanted too much male nudity." It was then offered to veteran director George Abbott, who found it to be difficult to handle alone. The biggest change Robbins made was adding a new opening number to replace "Love Is in the Air" and introduce the show as a bawdy, wild comedy. Stephen Sondheim wrote the song "Comedy Tonight" for this new opening. From that point on, the show was a success. It was directed by George Abbott and produced by Hal Prince, with choreography by Jack Cole and uncredited staging and choreography by Robbins. The scenic and costume design was by Tony Walton. The wardrobe is on display at the Costume World Broadway Collection in Pompano Beach, Florida. The lighting design was by Jean Rosenthal. Along with Mostel, the musical featured a cast of seasoned performers, including Jack Gilford (Mostel's friend and fellow blacklist member), David Burns, John Carradine, Ruth Kobart, and Raymond Walburn. The young lovers were played by Brian Davies and Preshy Marker. Karen Black, originally cast as the ingenue, was replaced out of town. The show won six Tony Awards, including Best Musical, Best Actor (Mostel), Best Supporting Actor (Burns), Best Book, and Best Director. The score, Sondheim's first Broadway production for which he wrote both music and lyrics, did not earn a nomination. London The show was presented twice in London's West End. The 1963 production and its 1986 revival were staged at the Strand Theatre and the Piccadilly Theatre respectively, and starred Frankie Howerd as Pseudolus and Leon Greene as Miles Gloriosus in both. In the 1963 production, Kenneth Connor appeared as Hysterium, 'Monsewer' Eddie Gray as Senex and Jon Pertwee as Marcus Lycus. In the 1986 revival, Patrick Cargill was Senex with Ronnie Stevens as Hysterium and Derek Royle as Erronius. In 2004 there was a limited-run revival at the Royal National Theatre, starring Desmond Barrit as Pseudolus, Philip Quast as Miles Gloriosus, Hamish McColl as Hysterium and Isla Blair as Domina (who had previously played Philia in the 1963 production). This production was nominated for the 2005 Olivier Award, Outstanding Musical Production. Motion picture adaptation Both Mostel and Gilford re-created their Broadway roles for the 1966 musical film directed by Richard Lester. Leon Greene reprised his West End role (Miles Gloriosus), while Phil Silvers portrayed Lycus, Michael Crawford portrayed Hero, and Michael Hordern played Senex. Buster Keaton made his final film appearance in the role of Erronius. Broadway revivals A revival opened on Broadway at the Lunt-Fontanne Theatre on April 4, 1972, and closed on August 12, 1972, after 156 performances. Directed by co-author Burt Shevelove the cast starred Phil Silvers as Pseudolus (later replaced by Tom Poston), Lew Parker as Senex, Carl Ballantine as Lycus and Reginald Owen as Erronius. Larry Blyden, who played Hysterium, the role created by Jack Gilford, also co-produced. "Pretty Little Picture" and "That'll Show Him" were dropped from the show, and were replaced with "Echo Song" (sung by Hero and Philia), and "Farewell" (added for Nancy Walker as Domina, as she and Senex depart for the country). "Echo Song" and "Farewell" had been added to a production staged in Los Angeles the previous year and were composed by Sondheim. They had to close soon after Phil Silvers suffered a stroke. The show won two Tony Awards, Best Leading Actor in a Musical for Silvers, and Best Featured Actor in a Musical for Blyden. The musical was revived again with great success in 1996, opening at the St. James Theatre on April 18, 1996, and closing on January 4, 1998, after 715 performances. The cast starred Nathan Lane as Pseudolus (replaced by Whoopi Goldberg and later by David Alan Grier), Mark Linn-Baker as Hysterium, Ernie Sabella as Lycus, Jim Stanek as Hero, Lewis J. Stadlen as Senex, and Cris Groenendaal as Miles Gloriosus. The production was directed by Jerry Zaks, with choreography by Rob Marshall. Lane won the 1996 Tony Award for Best Leading Actor and the Drama Desk Award, Outstanding Actor in a Musical; the production was nominated for the 1996 Tony Award and Drama Desk Award, Revival of a Musical. Every actor who has opened in the role of Pseudolus on Broadway (Zero Mostel, Phil Silvers, and Nathan Lane) has won a Best Leading Actor Tony Award for his performance. In addition, Jason Alexander, who performed as Pseudolus in one scene in Jerome Robbins' Broadway, also won a Tony for Best Actor in a Musical. Other productions The original Australian production with American actor Jack Collins as Pseudolus opened at the Theatre Royal in Sydney in July 1964, and toured other Australian cities through 1965. A production was directed by Stephen R. Buss at Boise State University in 1995, starring James B. Fisk, Randy Davison, Karen Wennstrom and Daniel Taylor. In 1998, Jon English starred as Pseudolus in Essgee Entertainment's production that opened New Year's Day at the State Theatre, Melbourne and toured Australia and New Zealand, closing September 1999. The Stephen Sondheim Center for the Performing Arts produced a limited-run revival of the musical from January 11 to 27, 2008. The production was directed by Randal K. West, with Justin Hill as musical director and Adam Cates as choreographer. The cast featured Richard Kind as Pseudolus, Joel Blum as Senex, Stephen DeRosa as Marcus Lycus, Sean McCall as Hysterium, and Steve Wilson as Miles Gloriosus. It also featured Diana Upton-Hill, Ryan Gaffney, Stephen Mark Crisp, Jack Kloppenborg, and Margret Clair. The Chung Ying Theatre Company in Hong Kong staged a Cantonese version of the musical at Kwai Tsing Theatre, to celebrate the company's 30th anniversary. It was directed by Chung King Fai and Ko Tin Lung and ran from March 14 to 21, 2009. The Stratford Shakespeare Festival in Stratford, Ontario, Canada production ran from June 11 to November 7, 2009, with Des McAnuff directing and Wayne Cilento as choreographer. Bruce Dow originally performed the role of Pseudolus, but was forced to withdraw from the entire 2009 season due to an injury, and the role was then performed by Seán Cullen as of September 5, 2009. Stephen Ouimette played Hysterium. Mirvish Productions presented the earlier Stratford production at the Canon Theatre, Toronto, in December 2010 through January 2011. Bruce Dow and Sean Cullen were alternates in the lead role. In October 2012 the play opened at Her Majesty's Theatre, Melbourne, Australia, with Geoffrey Rush as Pseudolus, Magda Szubanski as Domina and Shane Bourne as Senex. A Funny Thing Happened on the Way to the Forum was produced at the Two River Theater in Red Bank, New Jersey from November 14, 2015 to December 13, 2015 with an all-male cast (Paul Castree, Eddie Cooper, Kevin Isola, David Josefsberg, Max Kumangai, Graham Rowat, Manny Stark, Bobby Conte Thornton, David Turner, Michael Urie, Tom Deckman, and Christopher Fitzgerald). Plot In ancient Rome, some neighbors live in three adjacent houses. In the center is the house of Senex, who lives there with wife Domina, son Hero, and several slaves, including head slave Hysterium and the musical's main character Pseudolus. A slave belonging to Hero, Pseudolus wishes to buy, win, or steal his freedom. One of the neighboring houses is owned by Marcus Lycus, who is a buyer and seller of beautiful women; the other belongs to the ancient Erronius, who is abroad searching for his long-lost children (stolen in infancy by pirates). One day, Senex and Domina go on a trip and leave Pseudolus in charge of Hero. Hero confides in Pseudolus that he is in love with the lovely Philia, one of the courtesans in the House of Lycus (albeit still a virgin). Pseudolus promises to help him win Philia's love in exchange for his own freedom. Unfortunately (as the two find out when they pay a visit on Lycus), Philia has been sold to the renowned warrior Miles Gloriosus, who is expected to claim her very soon. Pseudolus, an excellent liar, uses Philia's cheery disposition to convince Lycus that she has picked up a plague from Crete, which causes its victims to smile endlessly in its terminal stages. By offering to isolate her in Senex's house, he is able to give Philia and Hero some time alone together, and the two fall in love. But Philia insists that, even though she is in love with Hero, she must honor her contract with the Captain, for "that is the way of a courtesan." To appease her, he tells her to wait ("that's what virgins do best, isn't it?") inside, and that he will have the captain knock three times when he arrives. Pseudolus comes up with a plan to slip Philia a sleeping potion that will render her unconscious. He will then tell Lycus that she has died of the Cretan plague, and will offer to remove the body. Hero will come along, and they will stow away on a ship headed for Greece. Satisfied with his plan, Pseudolus steals Hysterium's book of potions and has Hero read him the recipe for the sleeping potion; the only ingredient he lacks is "mare's sweat", and Pseudolus goes off in search of some. Unexpectedly, Senex returns home early from his trip, and knocks three times on his own door. Philia comes out of the house, and, thinking that Senex is the Captain, offers herself up to him. Surprised but game, Senex instructs Philia to wait in the house for him, and she does. Hysterium arrives to this confusion, and tells Senex that Philia is the new maid that he has hired. Pseudolus returns, having procured the necessary mare's sweat; seeing that Senex has returned unexpectedly and grasping the need to keep him out of the way, Pseudolus discreetly sprinkles some of the horse-sweat onto him, then suggests that the road trip has left Senex in dire need of a bath. Taking the bait, Senex instructs Hysterium to draw him a bath in the long-abandoned house of Erronius. But while this is happening, Erronius returns home, finally having given up the search for his long-lost children. Hysterium, desperate to keep him out of the house where his master is bathing, tells the old man that his house has become haunted – a story seemingly confirmed by the sound of Senex singing in his bath. Erronius immediately determines to have a soothsayer come and banish the spirit from his house, and Pseudolus obligingly poses as one, telling Erronius that, in order to banish the spirit, he must travel seven times around the seven hills of Rome (thus keeping the old man occupied and out of the way for quite a while). When Miles Gloriosus arrives to claim his courtesan-bride, Pseudolus hides Philia on the roof of Senex's house; told that she has "escaped", Lycus is terrified to face the Captain's wrath. Pseudolus offers to impersonate Lycus and talk his way out of the mess but, his ingenuity flagging, he ends up merely telling the Captain that Philia has disappeared, and that he, "Lycus", will search for her. Displeased and suspicious, Miles insists that his soldiers accompany Pseudolus, but the wily slave loses them in Rome's winding streets. Complicating matters further, Domina returns from her trip early, suspicious that her husband Senex is "up to something low." She disguises herself in virginal white robes and a veil (much like Philia's) to try to catch Senex being unfaithful. Pseudolus convinces Hysterium to help him by dressing in drag and pretending to be Philia, "dead" from the plague. Unfortunately, it turns out that Miles Gloriosus has just returned from Crete, where there is of course no actual plague. With the ruse thus revealed, the main characters run for their lives, resulting in a madcap chase across the stage with both Miles and Senex pursuing all three "Philia"s (Domina, Hysterium, and the actual Philia – all wearing identical white robes and veils). Meanwhile, the courtesans from the house of Marcus Lycus – who had been recruited as mourners at "Philia"'s ersatz funeral – have escaped, and Lycus sends his eunuchs out to bring them all back, adding to the general pandemonium. Finally, the Captain's troops are able to round everyone up. His plot thoroughly unraveled, Pseudolus appears to be in deep trouble – but Erronius, completing his third circuit of the Roman hills, shows up fortuitously to discover that Miles Gloriosus and Philia are wearing matching rings which mark them as his long-lost children. Philia's betrothal to the Captain is nullified by the unexpected revelation that he is her brother, and, as the daughter of a free-born citizen, she is freed from Marcus Lycus. Philia weds Hero with Erronius' blessing; Pseudolus gets his freedom and the lovely courtesan Gymnasia; Gloriosus receives twin courtesans to replace Philia; and Erronius is reunited with his children. A happy ending prevails for all – except for poor Senex, stuck with his shrewish wife Domina. Characters Pseudolus: A Roman slave, owned by Hero, who seeks to win freedom by helping Hero win the heart of Philia. The slave name Pseudolus means "Faker". While originally written as a male role, it has been performed by female actors as well. Hero: Young son of Senex who falls in love with the virgin, Philia. Philia: (Greek for "love") A virgin in the house of Marcus Lycus, and Hero's love interest. Her name is also a homophone of the Latin word "Filia", which means daughter. This foreshadows her status as the daughter of Erronius. Hysterium: (Latin for "Hysterical", or "Anxious", the suffix "-um" makes the name neuter, and the character's gender is often mistaken throughout the piece) The chief slave in the house of Senex. Senex: (Latin for "old man") A henpecked, sardonic Roman senator living in a less fashionable suburb of Rome. Domina: (Latin for "mistress") The wife of Senex. A manipulative, shrewish woman who is loathed by even her husband. Marcus Lycus: A purveyor of courtesans, who operates from the house to the left of Senex. (Name based on Lycus, the pimp in Plautus's Poenulus.) Miles Gloriosus: (Latin for "boastful soldier", the archetype of the braggart soldier in Roman comedies) A captain in the Roman army to whom Marcus Lycus has promised Philia. Erronius: (Latin for "wandering") Senex's elderly neighbor in the house to the right. He has spent the past twenty years searching for his two children, kidnapped in infancy by pirates. Gymnasia: (Greek for "Athletic", with the connotation of nakedness) A courtesan from the house of Lycus with whom Pseudolus falls in love. Tintinabula: (Latin for "Bells") A jingling, bell-wearing courtesan in the house of Lycus. Vibrata: (Latin for "Vibrant") A wild, vibrant courtesan in the house of Lycus. Geminae: (Latin for "Twins") Twin courtesans in the house of Lycus. Panacea: (Greek for "Cure All") A courtesan in the house of Lycus. Proteans: Choristers who play multiple roles (slaves, citizens, soldiers, and eunuchs). They accompany Pseudolus in "Comedy Tonight". They are referred to as "Three who do the work of thirty".

Aleut

The Aleuts ( ; ) are the Indigenous people of the Aleutian Islands, which are located between the North Pacific Ocean and the Bering Sea. Both the Aleut people and the islands are politically divided between the US state of Alaska and the Russian administrative division of Kamchatka Krai. This group is also known as the Unangax̂ (Oo-NUNG-ukh) in Unangam Tunuu, the Aleut language. Etymology In the Aleut language they are known by the endonyms Unangan (eastern dialect) and Unangas (western dialect), both of which mean "people". The Russian term "Aleut" was a general term used for both the native population of the Aleutian Islands and their neighbors to the east in the Kodiak Archipelago, who were also referred to as "Pacific Eskimos" or Sugpiat/Alutiit. Language Aleut people speak Unangam Tunuu, the Aleut language, as well as English and Russian in the United States and Russia respectively. An estimated 150 people in the United States and five people in Russia speak Aleut. The language belongs to the Eskimo–Aleut language family and includes three dialects: Eastern Aleut, spoken on the Eastern Aleutian, Shumagin, Fox and Pribilof Islands; Atkan, spoken on Atka and Bering islands; and the now extinct Attuan dialect. The Pribilof Islands has the highest number of active speakers of Unangam Tunuu. Most native elders speak Aleut, but it is rare for common people to speak the language fluently. Beginning in 1829, Aleut was written in the Cyrillic script. From 1870, the language has been written in the Latin script. An Aleut dictionary and grammar have been published, and portions of the Bible were translated into Aleut. Tribes The Aleut (Unangan) dialects and tribes: Attuan dialect and speaking tribes: Sasignan (in Attuan dialect)/Sasxnan (in Eastern dialect)/Sasxinas (in Western dialect) or Near Islanders: in the Near Islands (Attu, Agattu, Semichi). Kasakam Unangangis (in Aleut, lit. 'Russian Aleut') or Copper Island Aleut: in the Commander Islands of Russian Federation (Bering, Medny). ? Qax̂un or Rat Islanders : in the Buldir Island and Rat Islands (Kiska, Amchitka, Semisopochnoi). Atkan dialect or Western Aleut or Aliguutax̂ (in Aleut) and speaking tribes: Naahmiĝus or Delarof Islanders : in the Delarof Islands (Amatignak) and Andreanof Islands (Tanaga). Niiĝuĝis or Andreanof Islanders : in the Andreanof Islands (Kanaga, Adak, Atka, Amlia, Seguam). Eastern Aleut dialect and speaking tribes: Akuuĝun or Uniiĝun or Islanders of the Four Mountains : in the Islands of Four Mountains (Amukta, Kagamil). Qawalangin or Fox Islanders : in the Fox Islands (Umnak, Samalga, western part of Unalaska). Qigiiĝun or Krenitzen Islanders : in the Krenitzin Islands (eastern part of Unalaska, Akutan, Akun, Tigalda). Qagaan Tayaĝungin or Sanak Islanders : in the Sanak Islands (Unimak, Sanak). Taxtamam Tunuu dialect of Belkofski. Qaĝiiĝun or Shumigan Islanders : in the Shumagin Islands. Population and distribution The Aleut people historically lived throughout the Aleutian Islands, the Shumagin Islands, and the far western part of the Alaska Peninsula, with an estimated population of around 25,000 prior to European contact. In the 1820s, the Russian-American Company administered a large portion of the North Pacific during a Russian-led expansion of the fur trade. They resettled many Aleut families to the Commander Islands (within the Aleutsky District of the Kamchatka Krai in Russia) and to the Pribilof Islands (in Alaska). These continue to have majority-Aleut communities. According to the 2000 Census, 11,941 people identified as being Aleut, while 17,000 identified as having partial Aleut ancestry. Prior to sustained European contact, approximately 25,000 Aleut lived in the archipelago. The Encyclopædia Britannica Online says more than 15,000 people have Aleut ancestry in the early 21st century. The Aleut suffered high fatalities in the 19th and early 20th centuries from Eurasian infectious diseases to which they had no immunity. In addition, the population suffered as their customary lifestyles were disrupted. Russian traders and later Europeans married Aleut women and had families with them. History After Russian contact After the arrival of Russian Orthodox missionaries in the late 18th century, many Aleuts became Christian. Of the numerous Russian Orthodox congregations in Alaska, most are majority Alaska Native or Native Alaskan in ethnicity. One of the earliest Christian martyrs in North America was Saint Peter the Aleut. Recorded uprising against the Russians In the 18th century, Russia promyshlenniki traders established settlements on the islands. There was high demand for the furs that the Aleut provided from hunting. In May 1784, local Aleuts revolted on Amchitka against the Russian traders. (The Russians had a small trading post there.) According to the Aleuts, in an account recorded by Japanese castaways and published in 2004, otters were decreasing year by year. The Russians paid the Aleuts less and less in goods in return for the furs they made. The Japanese learned that the Aleuts felt the situation was at crisis. The leading Aleuts negotiated with the Russians, saying they had failed to deliver enough supplies in return for furs. Nezimov, leader of the Russians, ordered two of his men, Stephanov ( ) and Kazhimov ( ) to kill his mistress Oniishin ( ), who was the Aleut chief's daughter, because he doubted that Oniishin had tried to dissuade her father and other leaders from pushing for more goods. After the four leaders had been killed, the Aleuts began to move from Amchitka to neighboring islands. Nezimov, leader of the Russian group, was jailed after the whole incident was reported to Russian officials. (According to , written by Katsuragawa Hoshū after interviewing Daikokuya Kōdayū.) Aleut genocide against Nicoleño Tribe in California According to Russian American Company (RAC) records translated and published in the Journal of California and Great Basin Anthropology, a 200-ton otter hunting ship named Il’mena with a mixed-nationality crew, including a majority Aleut contingent, was involved in conflict resulting in a massacre of the indigenous natives of San Nicolas Island. In 1811, to obtain more of the commercially valuable otter pelts, a party of Aleut hunters traveled to the coastal island of San Nicolas, near the Alta California-Baja California border. The locally resident Nicoleño nation sought a payment from the Aleut hunters for the large number of otters being killed in the area. Disagreement arose, turning violent; in the ensuing battle, the Aleut killed nearly all the Nicoleño men. Together with high fatalities from European diseases, the Nicoleños suffered so much from the loss of their men that by 1853, only one Nicoleñan (Juana Maria, the Lone Woman of San Nicolas) remained alive. Internment during World War II In June 1942, during World War II, Japanese forces occupied Kiska and Attu Islands in the western Aleutians. They later transported captive Attu Islanders to Hokkaidō, where they were held as prisoners of war in harsh conditions. Fearing a Japanese attack on other Aleutian Islands and mainland Alaska, the U.S. government evacuated hundreds more Aleuts from the western chain and the Pribilofs, placing them in internment camps in southeast Alaska, where many died of measles, influenza and other infectious diseases which spread quickly in the overcrowded dormitories. In total, about 75 died in American internment and 19 as a result of Japanese occupation. The Aleut Restitution Act of 1988 was an attempt by Congress to compensate the survivors. On June 17, 2017, the U.S. Government formally apologized for the internment of the Unangan people and their treatment in the camps. The World War II campaign by the United States to retake Attu and Kiska was a significant component of the operations in the American and Pacific theaters. Population decline Before major influence from outside, there were approximately 25,000 Aleuts on the archipelago. Foreign diseases, harsh treatment and disruption of aboriginal society soon reduced the population to less than one-tenth this number. The 1910 Census count showed 1,491 Aleuts. In the 2000 Census, 11,941 people identified as being Aleut; nearly 17,000 said Aleuts were among their ancestors. Culture Housing The Aleut constructed partially underground houses called barabara. According to Lillie McGarvey, a 20th-century Aleut leader, s keep "occupants dry from the frequent rains, warm at all times, and snugly sheltered from the high winds common to the area". Aleuts traditionally built houses by digging an oblong square pit in the ground, usually or smaller. The pit was then covered by a roof framed with driftwood, thatched with grass, then covered with earth for insulation. Inside trenches were dug along the sides, with mats placed on top to keep them clean. The bedrooms were at the back of the lodge, opposite the entrance. Several families would stay in one house, with their own designated areas. Rather than fireplaces or bonfires in the middle, lanterns were hung in the house. Subsistence The Aleut survived by hunting and gathering. They fished for salmon, crabs, shellfish, and cod, as well as hunting sea mammals such as seal, walrus, and whales. They processed fish and sea mammals in a variety of ways: dried, smoked, or roasted. Caribou, muskoxen, deer, moose, whale, and other types of game were eaten roasted or preserved for later use. They dried berries. They were also processed as , a mixture of berries, fat, and fish. The boiled skin and blubber of a whale is a delicacy, as is that of walrus. Today, many Aleut continue to eat customary and locally sourced foods but also buy processed foods from Outside, which is expensive in Alaska. Ethnobotany A full list of their ethnobotany has been compiled, with 65 documented plant uses. Visual arts Customary arts of the Aleut include weapon-making, building of baidarkas (special hunting boats), weaving, figurines, clothing, carving, and mask making. Men as well as women often carved ivory and wood. Nineteenth century craftsmen were famed for their ornate wooden hunting hats, which feature elaborate and colorful designs and may be trimmed with sea lion whiskers, feathers, and walrus ivory. Andrew Gronholdt of the Shumagin Islands has played a vital role in reviving the ancient art of building the chagudax or bentwood hunting visors. Aleut women sewed finely stitched, waterproof parkas from seal gut and wove fine baskets from sea-lyme grass (Elymus mollis). Some Aleut women continue to weave ryegrass baskets. Aleut arts are practiced and taught throughout the state of Alaska. As many Aleut have moved out of the islands to other parts of the state, they have taken with them the knowledge of their arts. They have also adopted new materials and methods for their art, including serigraphy, video art, and installation art. Aleut carving, distinct in each region, has attracted traders for centuries, including early Europeans and other Alaska Natives. Historically, carving was a male art and leadership attribute whereas today it is done by both genders. Most commonly the carvings of walrus ivory and driftwood originated as part of making hunting weapons. Sculptural carvings depict local animals, such as seals and whales. Aleut sculptors also have carved human figures. The Aleut also carve walrus ivory for other uses, such as jewelry and sewing needles. Jewelry is made with designs specific to the region of each people. Each clan would have a specific style to signify their origin. Jewelry ornaments were made for piercing lips (labrum), nose, and ears, as well as for necklaces. Each woman had her own sewing needles, which she made, and that often had detailed end of animal heads. The main Aleut method of basketry was false embroidery (overlay). Strands of grasses or reeds were overlaid upon the basic weaving surface, to obtain a plastic effect. Basketry was an art reserved for women. Early Aleut women created baskets and woven mats of exceptional technical quality, using only their thumbnail, grown long and then sharpened, as a tool. Today, Aleut weavers continue to produce woven grass pieces of a remarkable cloth-like texture, works of modern art with roots in ancient tradition. Birch bark, puffin feathers, and baleen are also commonly used by the Aleut in basketry. The Aleut term for grass basket is . One Aleut leader recognized by the State of Alaska for her work in teaching and reviving Aleut basketry was Anfesia Shapsnikoff. Her life and accomplishments are portrayed in the book Moments Rightly Placed (1998). Masks were created to portray figures of their myths and oral history. The Atka people believed that another people lived in their land before them. They portrayed such ancients in their masks, which show anthropomorphic creatures named in their language. Knut Bergsland says their word means "like those found in caves." Masks were generally carved from wood and were decorated with paints made from berries or other natural products. Feathers were inserted into holes carved out for extra decoration. These masks were used in ceremonies ranging from dances to praises, each with its own meaning and purpose. Tattoos and piercings The tattoos and piercings of the Aleut people demonstrated accomplishments as well as their religious views. They believed their body art would please the spirits of the animals and make any evil go away. The body orifices were believed to be pathways for the entry of evil entities. By piercing their orifices: the nose, the mouth, and ears, they would stop evil entities, , from entering their bodies. Body art also enhanced their beauty, social status, and spiritual authority. Before the 19th century, piercings and tattoos were very common among the Aleut people, especially among women. Piercings, such as the nose pin, were common among both men and women and were usually performed a few days after birth. The ornament was made of various materials, a piece of bark or bone, or an eagle's feather shaft. From time to time, adult women decorated the nose pins by hanging pieces of amber and coral from strings on it; the semi-precious objects dangled down to their chins. Piercing ears was also common. The Aleuts pierced holes around the rim of their ears with dentalium shells (tooth shells or tusk shells), bone, feathers, dried bird wings or skulls and/or amber. Materials associated with birds were important, as birds were considered to defend animals in the spirit world. A male would wear sea lion whiskers in his ears as a trophy of his expertise as a hunter. Worn for decorative reasons, and sometimes to signify social standing, reputation, and the age of the wearer, Aleuts would pierce their lower lips with walrus ivory and wear beads or bones. The individual with the most piercings held the highest respect. Tattooing for women began when they reached physical maturity, after menstruation, at about age 20. Historically, men received their first tattoo after killing their first animal, an important rite of passage. Sometimes tattoos signaled social class. For example, the daughter of a wealthy, famous ancestor or father would work hard at her tattoos to show the accomplishments of that ancestor or father. They would sew, or prick, different designs on the chin, the side of the face, or under the nose. Aleut clothing The Aleut people developed in one of the harshest climates in the world, and learned to create and protect warmth. Both men and women wore parkas that extended below the knees. The women wore the skin of seal or sea-otter, and the men wore bird skin parkas, the feathers turned in or out depending on the weather. When the men were hunting on the water, they wore waterproof parkas made from seal or sea-lion guts, or the entrails of bear, walrus, or whales. Parkas had a hood that could be cinched, as could the wrist openings, so water could not get in. Men wore breeches made from the esophageal skin of seals. Children wore parkas made of downy eagle skin with tanned bird skin caps. They called these parkas , meaning 'rain gear' in the English language. Sea-lions, harbor seals, and sea otters are the most abundant marine mammals. The men brought home the skins and prepared them by soaking them in urine and stretching them. The women undertook the sewing. Preparation of the gut for clothing involved several steps. The prepared intestines were turned inside out. A bone knife was used to remove the muscle tissue and fat from the walls of the intestine. The gut was cut and stretched, and fastened to stakes to dry. It was then cut and sewn to make waterproof parkas, bags, and other receptacles. On some hunting trips, the men would take several women with them. They would catch birds and prepare the carcasses and feathers for future use. They caught puffins (Lunda cirrhata, Fratercula corniculata), guillemots, and murres. It took 40 skins of tufted puffin and 60 skins of horned puffin to make one parka. A woman would need a year for all the labor to make one parka. Each lasted two years with proper care. All parkas were decorated with bird feathers, beard bristles of seal and sea-lion, beaks of sea parrots, bird claws, sea otter fur, dyed leather, and caribou hair sewn in the seams. Women made needles from the wing bones of seabirds. They made thread from the sinews of different animals and fish guts. A thin strip of seal intestine could also be used, twisted to form a thread. The women grew their thumbnail extra long and sharpened it. They could split threads to make them as fine as a hair. They used vermilion paint, hematite, the ink bag of the octopus, and the root of a kind of grass or vine to color the threads. Gender Russian travelers making early contact with the Aleut mention traditional tales of two-spirits or third and fourth gender people, known as (male-bodied, 'man transformed into a woman') and (female-bodied, 'woman transformed into a man'), but it is unclear whether these tales are about historical individuals or spirits. Hunting technologies Boats The interior regions of the rough, mountainous Aleutian Islands provided little in terms of natural resources for the Aleutian people. They collected stones for weapons, tools, stoves or lamps. They collected and dried grasses for their woven baskets. For everything else, the Aleuts had learned to use the fish and mammals they caught and processed to satisfy their needs. To hunt sea mammals and to travel between islands, the Aleuts became experts of sailing and navigation. While hunting, they used small watercraft called baidarkas. For regular travel, they used their large s. The was a large, open, walrus-skin-covered boat. Aleut families used it when traveling among the islands. It was also used to transport goods for trade, and warriors took them to battle. The (small skin boat) was a small boat covered in sea lion skin. It was developed and used for hunting because of its sturdiness and maneuverability. The Aleut resembles that of a Yup'ik kayak, but it is hydrodynamically sleeker and faster. They made the for one or two persons only. The deck was made with a sturdy chamber, the sides of the craft were nearly vertical and the bottom was rounded. Most one-man s were about long and wide, whereas a two-man was on average about long and wide. It was from the that Aleut men would stand on the water to hunt from the sea. Weapons The Aleuts hunted small sea mammals with barbed darts and harpoons slung from throwing boards. These boards gave precision as well as some extra distance to these weapons. Harpoons were also called throwing-arrows when the pointed head fit loosely into the socket of the foreshaft and the head was able to detach from the harpoon when it penetrated an animal, and remain in the wound. There were three main kinds of harpoon that the Aleuts used: a simple harpoon, with a head that kept its original position in the animal after striking, a compound (toggle-head) harpoon in which the head took a horizontal position in the animal after penetration, and the throwing-lance used to kill large animals. The simple Aleut harpoon consisted of four main parts: the wooden shaft, the bone foreshaft, and the bonehead (tip) with barbs pointed backward. The barbed head was loosely fitted into the socket of the foreshaft so that when the animal was stabbed, it pulled the head away from the rest of the harpoon. The sharp barbs penetrated with ease, but could not be pulled out. The bone tip is fastened to a length of braided twine meanwhile; the hunter held the other end of the twine in his hand. The compound harpoon was the most prevalent weapon of the Aleut people. Also known as the toggle-head spear, it was about the same size as the simple harpoon and used to hunt the same animals, however, this harpoon provided a more efficient and lethal weapon. This harpoon separated into four parts. The longest part was the shaft with the thicker stalk closer to the tip of the harpoon. The shaft was fitted into the socket of the fore shaft and a bone ring was then placed over the joint to hold the two pieces together, as well as, protecting the wooden shaft from splitting. Connected to the fore shaft of the harpoon is the toggle head spear tip. This tip was made of two sub shafts that break apart on impact with an animal. The upper sub shaft held the razor stone head and attached to the lower sub shaft with a small braided twine loop. Once the tip penetrates the animal the upper sub head broke off from the rest of the shaft, however, since it was still connected with the braided loop it rotated the head into a horizontal position inside the animal's body so that it could not get away from the hunter. The throwing lance may be distinguished from a harpoon because all its pieces are fixed and immovable. A lance was a weapon of war and it was also used to kill large marine animals after it has already been harpooned. The throwing lance usually consisted of three parts: a wooden shaft, a bone ring or belt, and the compound head that was made with a barbed bonehead and a stone tip. The length of the compound head was equivalent to the distance between the planes of a man's chest to his back. The lance would penetrate the chest and pass through the chest cavity and exit from the back. The bone ring was designed to break after impact so that the shaft could be used again for another kill. Burial practices They buried their dead ancestors near the village. Archeologists have found many different types of burials, dating from a variety of periods, in the Aleutian Islands. The Aleut developed a style of burials that were accommodated to local conditions, and honored the dead. They have had four main types of burials: , cave, above-ground sarcophagi, and burials connected to communal houses. burials are the most widely known type of mortuary practice found in the Aleutian Islands. The people created burial mounds, that tend to be located on the edge of a bluff. They placed stone and earth over the mound to protect and mark it. Such mounds were first excavated by archeologists in 1972 on Southwestern Unmak Island, and dated to the early contact period. Researchers have found a prevalence of these burials, and concluded it is a regional mortuary practice. It may be considered a pan-Aleutian mortuary practice. Cave burials have been found throughout the eastern Aleutian Islands. The human remains are buried in shallow graves at the rear of the cave. These caves tend to be next to middens and near villages. Some grave goods have been found in the caves associated with such burials. For example, a deconstructed boat was found in a burial cave on Kanaga Island. There were no other major finds of grave goods in the vicinity. Throughout the Aleutian Islands, gravesites have been found that are above-ground sarcophagi. These sarcophagi are left exposed, with no attempt to bury the dead in the ground. These burials tend to be isolated and limited to the remains of adult males, which may indicate a specific ritual practice. In the Near Islands, isolated graves have also been found with the remains, and not just the sarcophagus, left exposed on the surface. This way of erecting sarcophagi above ground is not as common as and cave burials, but it is still widespread. Another type of practice has been to bury remains in areas next to the communal houses of the settlement. Human remains are abundant in such sites. They indicate a pattern of burying the dead within the main activity areas of the settlement. These burials consist of small pits adjacent to the houses and scattered around them. In these instances, mass graves are common for women and children. This type of mortuary practice has been mainly found in the Near Islands. In addition to these four main types, other kinds of burials have been found in the Aleutian Islands. These more isolated examples in include mummification, private burial houses, abandoned houses, etc. To date, such examples are not considered to be part of a larger, unifying cultural practice. The findings discussed represent only the sites that have been excavated. The variety of mortuary practices mostly did not include the ritual of including extensive grave goods, as has been found in other cultures. The remains so far have been mainly found with other human and faunal remains. The addition of objects to "accompany" the dead is rare. Archaeologists have been trying to dissect the absence of grave goods, but their findings have been ambiguous and do not really help the academic community to understand these practices more. Not much information is known about the ritual parts of burying the dead. Archeologists and anthropologists have not found much evidence related to burial rituals. This lack of ritual evidence could hint at either no ritualized ceremony, or one that has not yet been revealed in the archaeological record. As a result, archaeologists cannot decipher the context to understand exactly why a certain type of burial was used in particular cases. Notable Aleuts John Hoover (1919–2011), sculptor Carl E.

Acid–base reaction

In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH via titration. Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory. Their importance becomes apparent in analyzing acid–base reactions for gaseous or liquid species, or when acid or base character may be somewhat less apparent. The first of these concepts was provided by the French chemist Antoine Lavoisier, around 1776. It is important to think of the acid–base reaction models as theories that complement each other. For example, the current Lewis model has the broadest definition of what an acid and base are, with the Brønsted–Lowry theory being a subset of what acids and bases are, and the Arrhenius theory being the most restrictive. Acid–base definitions Historic development The concept of an acid–base reaction was first proposed in 1754 by Guillaume-François Rouelle, who introduced the word "base" into chemistry to mean a substance which reacts with an acid to give it solid form (as a salt). Bases are mostly bitter in nature. Lavoisier's oxygen theory of acids The first scientific concept of acids and bases was provided by Lavoisier in around 1776. Since Lavoisier's knowledge of strong acids was mainly restricted to oxoacids, such as (nitric acid) and (sulfuric acid), which tend to contain central atoms in high oxidation states surrounded by oxygen, and since he was not aware of the true composition of the hydrohalic acids (HF, HCl, HBr, and HI), he defined acids in terms of their containing oxygen, which in fact he named from Greek words meaning "acid-former" (). The Lavoisier definition held for over 30 years, until the 1810 article and subsequent lectures by Sir Humphry Davy in which he proved the lack of oxygen in hydrogen sulfide (), hydrogen telluride (), and the hydrohalic acids. However, Davy failed to develop a new theory, concluding that "acidity does not depend upon any particular elementary substance, but upon peculiar arrangement of various substances". One notable modification of oxygen theory was provided by Jöns Jacob Berzelius, who stated that acids are oxides of nonmetals while bases are oxides of metals. Liebig's hydrogen theory of acids In 1838, Justus von Liebig proposed that an acid is a hydrogen-containing compound whose hydrogen can be replaced by a metal. This redefinition was based on his extensive work on the chemical composition of organic acids, finishing the doctrinal shift from oxygen-based acids to hydrogen-based acids started by Davy. Liebig's definition, while completely empirical, remained in use for almost 50 years until the adoption of the Arrhenius definition. Arrhenius definition The first modern definition of acids and bases in molecular terms was devised by Svante Arrhenius. A hydrogen theory of acids, it followed from his 1884 work with Friedrich Wilhelm Ostwald in establishing the presence of ions in aqueous solution and led to Arrhenius receiving the Nobel Prize in Chemistry in 1903. As defined by Arrhenius: An Arrhenius acid is a substance that ionises in water to form hydrogen ions (); that is, an acid increases the concentration of H+ ions in an aqueous solution. This causes the protonation of water, or the creation of the hydronium () ion. Thus, in modern times, the symbol is interpreted as a shorthand for , because it is now known that a bare proton does not exist as a free species in aqueous solution. This is the species which is measured by pH indicators to measure the acidity or basicity of a solution. An Arrhenius base is a substance that dissociates in water to form hydroxide () ions; that is, a base increases the concentration of ions in an aqueous solution. The Arrhenius definitions of acidity and alkalinity are restricted to aqueous solutions and are not valid for most non-aqueous solutions, and refer to the concentration of the solvent ions. Under this definition, pure and HCl dissolved in toluene are not acidic, and molten NaOH and solutions of calcium amide in liquid ammonia are not alkaline. This led to the development of the Brønsted–Lowry theory and subsequent Lewis theory to account for these non-aqueous exceptions. The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. In this traditional representation an acid–base neutralization reaction is formulated as a double-replacement reaction. For example, the reaction of hydrochloric acid (HCl) with sodium hydroxide (NaOH) solutions produces a solution of sodium chloride (NaCl) and some additional water molecules. The modifier (aq) in this equation was implied by Arrhenius, rather than included explicitly. It indicates that the substances are dissolved in water. Though all three substances, HCl, NaOH and NaCl are capable of existing as pure compounds, in aqueous solutions they are fully dissociated into the aquated ions and . Example: baking soda When combined with water, the sodium bicarbonate (baking soda, ) and acid salts react to produce gaseous carbon dioxide. Whether commercially or domestically prepared, the principles behind baking soda formulations remain the same. The acid–base reaction can be generically represented as shown: The real reactions are more complicated because the acids are complicated. For example, starting with sodium bicarbonate and monocalcium phosphate (), the reaction produces carbon dioxide by the following stoichiometry: A typical formulation (by weight) could call for 30% sodium bicarbonate, 5–12% monocalcium phosphate, and 21–26% sodium aluminium sulfate. Alternately, a commercial baking powder might use sodium acid pyrophosphate as one of the two acidic components instead of sodium aluminium sulfate. Another typical acid in such formulations is cream of tartar (), a derivative of tartaric acid. Brønsted–Lowry definition The Brønsted–Lowry definition, formulated in 1923, independently by Johannes Nicolaus Brønsted in Denmark and Martin Lowry in England, is based upon the idea of protonation of bases through the deprotonation of acids – that is, the ability of acids to "donate" hydrogen ions () otherwise known as protons to bases, which "accept" them. An acid–base reaction is, thus, the removal of a hydrogen ion from the acid and its addition to the base. The removal of a hydrogen ion from an acid produces its conjugate base, which is the acid with a hydrogen ion removed. The reception of a proton by a base produces its conjugate acid, which is the base with a hydrogen ion added. Unlike the previous definitions, the Brønsted–Lowry definition does not refer to the formation of salt and solvent, but instead to the formation of conjugate acids and conjugate bases, produced by the transfer of a proton from the acid to the base. In this approach, acids and bases are fundamentally different in behavior from salts, which are seen as electrolytes, subject to the theories of Debye, Onsager, and others. An acid and a base react not to produce a salt and a solvent, but to form a new acid and a new base. The concept of neutralization is thus absent. Brønsted–Lowry acid–base behavior is formally independent of any solvent, making it more all-encompassing than the Arrhenius model. The calculation of pH under the Arrhenius model depended on alkalis (bases) dissolving in water (aqueous solution). The Brønsted–Lowry model expanded what could be pH tested using insoluble and soluble solutions (gas, liquid, solid). The general formula for acid–base reactions according to the Brønsted–Lowry definition is: where HA represents the acid, B represents the base, represents the conjugate acid of B, and represents the conjugate base of HA. For example, a Brønsted–Lowry model for the dissociation of hydrochloric acid (HCl) in aqueous solution would be the following: The removal of from the produces the chloride ion, , the conjugate base of the acid. The addition of to the (acting as a base) forms the hydronium ion, , the conjugate acid of the base. Water is amphoteric that is, it can act as both an acid and a base. The Brønsted–Lowry model explains this, showing the dissociation of water into low concentrations of hydronium and hydroxide ions: This equation is demonstrated in the image below: Here, one molecule of water acts as an acid, donating an and forming the conjugate base, , and a second molecule of water acts as a base, accepting the ion and forming the conjugate acid, . As an example of water acting as an acid, consider an aqueous solution of pyridine, . In this example, a water molecule is split into a hydrogen ion, which is donated to a pyridine molecule, and a hydroxide ion. In the Brønsted–Lowry model, the solvent does not necessarily have to be water, as is required by the Arrhenius Acid–Base model. For example, consider what happens when acetic acid, , dissolves in liquid ammonia. An ion is removed from acetic acid, forming its conjugate base, the acetate ion, . The addition of an ion to an ammonia molecule of the solvent creates its conjugate acid, the ammonium ion, . The Brønsted–Lowry model calls hydrogen-containing substances (like ) acids. Thus, some substances, which many chemists considered to be acids, such as or , are excluded from this classification due to lack of hydrogen. Gilbert N. Lewis wrote in 1938, "To restrict the group of acids to those substances that contain hydrogen interferes as seriously with the systematic understanding of chemistry as would the restriction of the term oxidizing agent to substances containing oxygen." Furthermore, and are not considered Brønsted bases, but rather salts containing the bases and . Lewis definition The hydrogen requirement of Arrhenius and Brønsted–Lowry was removed by the Lewis definition of acid–base reactions, devised by Gilbert N. Lewis in 1923, in the same year as Brønsted–Lowry, but it was not elaborated by him until 1938. Instead of defining acid–base reactions in terms of protons or other bonded substances, the Lewis definition defines a base (referred to as a Lewis base) to be a compound that can donate an electron pair, and an acid (a Lewis acid) to be a compound that can receive this electron pair. For example, boron trifluoride, is a typical Lewis acid. It can accept a pair of electrons as it has a vacancy in its octet. The fluoride ion has a full octet and can donate a pair of electrons. Thus is a typical Lewis acid, Lewis base reaction. All compounds of group 13 elements with a formula can behave as Lewis acids. Similarly, compounds of group 15 elements with a formula , such as amines, , and phosphines, , can behave as Lewis bases. Adducts between them have the formula with a dative covalent bond, shown symbolically as ←, between the atoms A (acceptor) and D (donor). Compounds of group 16 with a formula may also act as Lewis bases; in this way, a compound like an ether, , or a thioether, , can act as a Lewis base. The Lewis definition is not limited to these examples. For instance, carbon monoxide acts as a Lewis base when it forms an adduct with boron trifluoride, of formula . Adducts involving metal ions are referred to as co-ordination compounds; each ligand donates a pair of electrons to the metal ion. The reaction can be seen as an acid–base reaction in which a stronger base (ammonia) replaces a weaker one (water) The Lewis and Brønsted–Lowry definitions are consistent with each other since the reaction is an acid–base reaction in both theories. Solvent system definition One of the limitations of the Arrhenius definition is its reliance on water solutions. Edward Curtis Franklin studied the acid–base reactions in liquid ammonia in 1905 and pointed out the similarities to the water-based Arrhenius theory. Albert F.O. Germann, working with liquid phosgene, , formulated the solvent-based theory in 1925, thereby generalizing the Arrhenius definition to cover aprotic solvents. Germann pointed out that in many solutions, there are ions in equilibrium with the neutral solvent molecules: solvonium ions: a generic name for positive ions. (The term solvonium has replaced the older term lyonium ions: positive ions formed by protonation of solvent molecules.) solvate ions: a generic name for negative ions. (The term solvate has replaced the older term lyate ions: negative ions formed by deprotonation of solvent molecules.) For example, water and ammonia undergo such dissociation into hydronium and hydroxide, and ammonium and amide, respectively: Some aprotic systems also undergo such dissociation, such as dinitrogen tetroxide into nitrosonium and nitrate, antimony trichloride into dichloroantimonium and tetrachloroantimonate, and phosgene into chlorocarboxonium and chloride: A solute that causes an increase in the concentration of the solvonium ions and a decrease in the concentration of solvate ions is defined as an acid. A solute that causes an increase in the concentration of the solvate ions and a decrease in the concentration of the solvonium ions is defined as a base. Thus, in liquid ammonia, (supplying ) is a strong base, and (supplying ) is a strong acid. In liquid sulfur dioxide (), thionyl compounds (supplying ) behave as acids, and sulfites (supplying ) behave as bases. The non-aqueous acid–base reactions in liquid ammonia are similar to the reactions in water: Nitric acid can be a base in liquid sulfuric acid: The unique strength of this definition shows in describing the reactions in aprotic solvents; for example, in liquid : Because the solvent system definition depends on the solute as well as on the solvent itself, a particular solute can be either an acid or a base depending on the choice of the solvent: is a strong acid in water, a weak acid in acetic acid, and a weak base in fluorosulfonic acid; this characteristic of the theory has been seen as both a strength and a weakness, because some substances (such as and ) have been seen to be acidic or basic on their own right. On the other hand, solvent system theory has been criticized as being too general to be useful. Also, it has been thought that there is something intrinsically acidic about hydrogen compounds, a property not shared by non-hydrogenic solvonium salts. Lux–Flood definition This acid–base theory was a revival of the oxygen theory of acids and bases proposed by German chemist Hermann Lux in 1939, further improved by Håkon Flood circa 1947 and is still used in modern geochemistry and electrochemistry of molten salts. This definition describes an acid as an oxide ion () acceptor and a base as an oxide ion donor. For example: This theory is also useful in the systematisation of the reactions of noble gas compounds, especially the xenon oxides, fluorides, and oxofluorides. Usanovich definition Mikhail Usanovich developed a general theory that does not restrict acidity to hydrogen-containing compounds, but his approach, published in 1938, was even more general than Lewis theory. Usanovich's theory can be summarized as defining an acid as anything that accepts negative species or donates positive ones, and a base as the reverse. This defined the concept of redox (oxidation-reduction) as a special case of acid–base reactions Some examples of Usanovich acid–base reactions include: Rationalizing the strength of Lewis acid–base interactions HSAB theory In 1963, Ralph Pearson proposed a qualitative concept known as the Hard and Soft Acids and Bases principle. later made quantitative with help of Robert Parr in 1984. 'Hard' applies to species that are small, have high charge states, and are weakly polarizable. 'Soft' applies to species that are large, have low charge states and are strongly polarizable. Acids and bases interact, and the most stable interactions are hard–hard and soft–soft. This theory has found use in organic and inorganic chemistry. ECW model The ECW model created by Russell S. Drago is a quantitative model that describes and predicts the strength of Lewis acid base interactions, . The model assigned and parameters to many Lewis acids and bases. Each acid is characterized by an and a . Each base is likewise characterized by its own and . The and parameters refer, respectively, to the electrostatic and covalent contributions to the strength of the bonds that the acid and base will form. The equation is The term represents a constant energy contribution for acid–base reaction such as the cleavage of a dimeric acid or base. The equation predicts reversal of acids and base strengths. The graphical presentations of the equation show that there is no single order of Lewis base strengths or Lewis acid strengths. Acid–base equilibrium The reaction of a strong acid with a strong base is essentially a quantitative reaction. For example, In this reaction both the sodium and chloride ions are spectators as the neutralization reaction, does not involve them. With weak bases addition of acid is not quantitative because a solution of a weak base is a buffer solution. A solution of a weak acid is also a buffer solution. When a weak acid reacts with a weak base an equilibrium mixture is produced. For example, adenine, written as AH, can react with a hydrogen phosphate ion, . The equilibrium constant for this reaction can be derived from the acid dissociation constants of adenine and of the dihydrogen phosphate ion. The notation [X] signifies "concentration of X". When these two equations are combined by eliminating the hydrogen ion concentration, an expression for the equilibrium constant, is obtained. Acid–alkali reaction An acid–alkali reaction is a special case of an acid–base reaction, where the base used is also an alkali. When an acid reacts with an alkali salt (a metal hydroxide), the product is a metal salt and water. Acid–alkali reactions are also neutralization reactions. In general, acid–alkali reactions can be simplified to by omitting spectator ions. Acids are in general pure substances that contain hydrogen cations () or cause them to be produced in solutions. Hydrochloric acid () and sulfuric acid () are common examples. In water, these break apart into ions: The alkali breaks apart in water, yielding dissolved hydroxide ions: See also Acid–base titration Deprotonation Donor number Electron configuration Gutmann–Beckett method Lewis structure Nucleophilic substitution Neutralization (chemistry) Protonation Redox reactions Resonance (chemistry) Notes References Sources External links Acid–base Physiology – an on-line text John W.

Abu al-Faraj al-Isfahani

Ali ibn al-Husayn al-Iṣfahānī (), also known as Abul-Faraj, (full form: Abū al-Faraj ʿAlī ibn al-Ḥusayn ibn Muḥammad ibn Aḥmad ibn al-Ḥaytham al-Umawī al-Iṣfahānī) (897-967CE / 284–356AH) was a writer, historian, genealogist, poet, musicologist and scribe. He was of Arab-Quraysh origin and mainly based in Baghdad. He is best known as the author of Kitab al-Aghani ("The Book of Songs"), which includes information about the earliest attested periods of Arabic music (from the seventh to the ninth centuries) and the lives of poets and musicians from the pre-Islamic period to al-Isfahani's time. Given his contribution to the documentation of the history of Arabic music, al-Isfahani is characterised by George Sawa as "a true prophet of modern ethnomusicology". Dates The commonly accepted dates of al-Isfahani's birth and death are 897–898 and 967, based on the dates given by al-Khatib al-Baghdadi which itself based its information on the testimony of al-Isfahani's student, Muhammad ibn Abi al-Fawaris. However, the credibility of these dates is to be treated with caution. No source places his death earlier than 967, but several place it later. These dates are at odds with a reference in the Kitab Adab al-ghuraba ("The Book of the Etiquettes of Strangers"), attributed to al-Isfahani, to his being in the prime of youth (fi ayyam al-shabiba wa-l-siba) in 967. Calculation of the approximate dates of his birth and death through the life spans of his students and his direct informants suggests that he was born before 902 and died after 960. Biography Abu al-Faraj al-Isfahani was born in Isfahan, Persia (present-day Iran) but spent his youth and undertook his early studies in Baghdad (present-day Iraq). He was a direct descendant of the last of the Umayyad caliphs, Marwan II, and was thus connected with the Umayyad rulers in al-Andalus, and seems to have kept up a correspondence with them and to have sent them some of his works. He became famous for his knowledge of early Arabian antiquities. His later life was spent in various parts of the Islamic world, including in Aleppo with its Hamdanid governor Sayf ad-Dawlah (to whom he dedicated the Book of Songs), and in Ray with the Buwayhid vizier Ibn 'Abbad. Family The epithet, al-Isfahani, refers to the city, Isfahan, on the Iranian plateau. Instead of indicating al-Isfahani's birthplace, this epithet seems to be common to al-Isfahani's family. Every reference al-Isfahani makes to his paternal relatives includes the attributive, al-Isfahani. According to Ibn Hazm (994–1064), some descendants of the last Umayyad caliph, Marwan b. Muhammad (691–750), al-Isfahani's ancestor, settled in Isfahan. However, it has to be borne in mind that the earliest information available regarding al-Isfahani's family history only dates to the generation of his great-grandfather, Ahmad b. al-Ḥaytham, who settled in Samarra sometime between 835–6 and 847. Based on al-Isfahani's references in the Kitab al-Aghani (hereafter, the Aghani), Ahmad b. al-Haytham seems to have led a privileged life in Sāmarrāʾ, while his sons were well-connected with the elite of the Abbasid capital at that time. His son, Abd al-Aziz b. Ahmad, was "one of the high ranking scribes in the days of al-Mutawakkil (r. 847–861) (min kibār al-kuttāb fī ayyām al-Mutawakkil)". Another son, Muhammad b. Ahmad (viz. al-Isfahani's grandfather), was associated with Abbasid officials, the vizier Ibn al-Zayyāt (d. 847), the scribe Ibrahim b. al-Abbas al-Ṣūlī (792–857), and the vizier Ubaydallah b. Sulayman (d. 901), along with the Ṭālibid notables, including al-Husayn b. al-Husayn b. Zayd, who was the leader of the Banu Hashim. The close ties with the Abbasid court continued with Muhammad's sons, al-Hasan and al-Husayn (al-Isfahani's father). In various places in the Aghani, al-Isfahani refers to Yahya b. Muhammad b. Thawaba (from the Al Thawaba) as his grandfather on his mother's side. It is often suggested that the family of Thawaba, being Shi'i, bequeathed their sectarian inclination to al-Isfahani. However, the identification of the Thawaba family as Shi'is is only found in a late source, Yaqut's (1178–1225) work. While many elite families working under the Abbasid caliphate were Shi'i-inclined, indeed allied with Alids or their partisans, there is no evidence that members of the Thawaba family embraced an extreme form of Shi'ism. In summary, al-Isfahani came from a family well-entrenched in the networks of the Abbasid elite, which included the officials and the Alids. Despite the epithet, al-Isfahani, it does not seem that the Isfahani family had a strong connection with the city of Isfahan. Rather, the family was mainly based in Sāmarrāʾ, from the generation of Ahmad b. al-Ḥaytham, and then Baghdad. In the seats of the caliphate, a few members of the al-Isfahani family worked as scribes, while maintaining friendship or alliance with other scribes, viziers and notables. Like many of the court elite, al-Isfahani's family maintained an amicable relationship with the offspring of Ali and allied with families, such as the Thawaba family, sharing their veneration of Ali and Alids. However, it is hard to pinpoint such a reverential attitude towards Alids in terms of sectarian alignment, given the scanty information about al-Isfahani's family and the fluidity of sectarian identities at the time. Education and career The Isfahani family's extensive network of contacts is reflected in al-Isfahani's sources. Among the direct informants whom al-Isfahani cites in his works, are members of his own family, who were further connected to other notable families, the Al Thawaba, the Banū Munajjim, the Yazīdīs, the Ṣūlīs, the Banū Ḥamdūn, the Ṭāhirids, the Banū al-Marzubān and the Ṭālibids. Given that al-Isfahani and his family very likely settled in Baghdad around the beginning of the tenth century, he interacted with a considerable number of the inhabitants of or visitors to that city, including: Jaḥẓa (d. 936), al-Khaffāf, Ali b. Sulaymān al-Akhfash (d. 927/8), and Muhammad b. Jarir al-Ṭabari (d. 922). Like other scholars of his time, al-Isfahani travelled in pursuit of knowledge. Although the details are insufficient to establish the dates of his journeys, based on the chains of transmission (asānīd, sing. isnād) al-Isfahani cites consistently and meticulously in every report, it is certain that he transmitted from ʿAbd al-Malik b. Maslama and ʿĀṣim b. Muhammad in Antakya; ʿAbdallāh b. Muhammad b. Ishaq in Ahwaz; and Yahya b. Aḥmad b. al-Jawn in Raqqa. If we accept the attribution of the Kitab Adab al-ghuraba to al-Isfahani, he once visited Baṣra as well as Ḥiṣn Mahdī, Mattūth, and Bājistrā. Yet, none of these cities seems to have left as much of an impact on al-Isfahani as Kūfa and Baghdad did. While al-Isfahani's Baghdadi informants were wide-ranging in their expertise as well as sectarian and theological tendencies, his Kūfan sources can be characterised as either Shi'i or keen on preserving and disseminating memories that favoured Ali and his family. For example, Ibn ʿUqda (d. 944), mentioned in both the Aghānī and the Maqātil, was invariably cited for the reports about the Alids and their merits. The journey in search for knowledge taken by al-Isfahani may not be particularly outstanding by the standard of his time, but the diversity of his sources' occupations and expertise is impressive. His informants can be assigned into one or more of the following categories: philologists and grammarians; singers and musicians; booksellers and copyists (sahhafun or warraqun, sing. sahhaf or Warraq); friends; tutors (muʾaddibūn, sing. muʾaddib); scribes (kuttāb, sing. kātib); imams or preachers (khuṭabāʾ, sing. khaṭīb); religious scholars (of the ḥadīth, the Qurʾānic recitations and exegeses, or jurisprudence) and judges; poets; and akhbārīs (transmitters of reports of all sorts, including genealogical, historical, and anecdotal reports). The variety of the narrators and their narrations enriched al-Iṣfahānī's literary output, which covers a wide range of topics from amusing tales to the accounts of the Alids' martyrdom. His erudition is best illustrated by Abu Ali al-Muhassin al-Tanukhi's (941–994) comment: "With his encyclopaedic knowledge of music, musicians, poetry, poets, genealogy, history, and other subjects, al-Iṣfahānī established himself as a learned scholar and teacher." He was also a scribe and this is not surprising, given his families’ scribal connections, but the details of his kātib activities are rather opaque. Although both al-Tanūkhī and al-Baghdādī refer to al-Isfahani with the attribute, kātib, they mention nothing of where he worked or for whom. The details of his occupation as a scribe only came later, with Yaqut, many of whose reports about al-Isfahani prove problematic. For instance, a report from Yaqut claims that al-Isfahani was the scribe of Rukn al-Dawla (d. 976) and mentions his resentment towards Abū al-Faḍl b. al-ʿAmīd (d. 970). However, the very same report was mentioned by Abū Ḥayyān al-Tawḥīdī (active tenth century) in his Akhlāq al-wazīrayn, where the scribe of Rukn al-Dawla is identified as Abū al-Faraj Ḥamd b. Muhammad, not Abū al-Faraj al-Isfahani. Thus, it is hard to know with certainty how and where al-Isfahani was engaged in his capacity as a kātib. Nevertheless, al-Isfahani's association with the vizier, Abū Muḥammad al-Muhallabī (903–963), is well-documented. The friendship between the two began before al-Muhallabī's became vizier in 950. The firm relationship between them is supported by al-Isfahani's poetry collected by al-Thaʿālibī (961–1038): half of the fourteen poems are panegyrics dedicated to al-Muhallabī. In addition, al-Isfahani's own work, al-Imāʾ al-shawāʿir (“Enslaved Women Who Composed Poetry”), is dedicated to the vizier, presumably, al-Muhallabī. His no longer surviving Manājīb al-khiṣyān (“The Noble Eunuchs”), which addresses two castrated male singers owned by al-Muhallabī, was composed for him. His magnum opus, the Aghānī, was very likely intended for al-Muhallabī, as well. In return for his literary efforts, according to al-Tanūkhī, al-Isfahani frequently received rewards from the vizier. Furthermore, for the sake of their long-term friendship and out of his respect for al-Isfahani's genius, al-Muhallabī exceptionally tolerated al-Isfahani's uncouth manners and poor personal hygiene. The sources say nothing about al-Isfahani's fate after al-Muhallabī's death. In his last years, according to his student, Muhammad b. Abī al-Fawāris, he suffered from senility (khallaṭa). Personality, preferences, and beliefs As a friend, al-Isfahani was unconventional in the sense that he did not seem to have been bothered to observe the social decorum of his time, as noted by a late biographical source: with his uncleanliness and gluttony, he presented a counterexample to elegance (ẓarf), as defined by one of his teachers, Abu al-Ṭayyib al-Washshāʾ (d. 937). His unconformity to the social norms did not hinder him from being part of al-Muhallabī's entourage or participation in the literary assemblies, but, inevitably, it resulted in frictions with other scholars and detraction by his enemies. Although al-Isfahani appeared eccentric to his human associates, he was a caring owner of his cat, named Yaqaq (white): he treated Yaqaq's colic (qulanj) with an enema (al-ḥuqna). In contrast to his personal habits, al-Isfahani's prose style is lucid, “in clear and simple language, with unusual sincerity and frankness”. Al-Isfahani's capacity as a writer is well illustrated by Abu Deeb, who depicts al-Isfahani as "one of the finest writers of Arabic prose in his time, with a remarkable ability to relate widely different types of aḵbār in a rich, lucid, rhythmic, and precise style, only occasionally exploiting such formal effects as saǰʿ (rhyming prose). He was also a fine poet with an opulent imagination. His poetry displays preoccupations similar to those of other urban poets of his time". His pinpoint documentation of asānīd and meticulous verification of information, provided in all his works, embody a truly scholarly character. Usually, in his treatment of a subject or an event, al-Isfahani lets his sources speak, but, occasionally, he voices his evaluation of poems and songs, as well as their creators. When dealing with conflicting reports, al-Isfahani either leaves his readers to decide or issues his judgement as to the most credible account. Yet, he frankly condemns sources whom he holds to be unreliable, for instance, Ibn Khurdādhbih on musicological information and Ibn al-Kalbī on genealogy. Indeed, al-Isfahani assesses his source material with a critical eye, while striving to present a more balanced view on his biographies, by focusing on their merits instead of elaborating on their flaws. That said, al-Isfahani's personal preferences and sectarian partisanship are not absent from his works. In terms of music and songs, al-Isfahani favours Ishaq b. Ibrahim al-Mawsili (772–850). In al-Isfahani's view, Ishaq b. Ibrahim was a multi-talented man, who excelled in a number of subjects, but, most importantly, music. Ishaq b. Ibrahim, as a collector of the reports about poets and singers, is an important source in his Aghānī. Besides being a mine of information, Ishaq b. Ibrahim's terminology for the description of the melodic modes is preferred over that of his opponent, Ibrahim ibn al-Mahdi (779–839), and adopted by al-Isfahani in his Aghani. Furthermore, al-Isfahani embarked on the compilation of the Aghānī because he was commissioned by his patron to reconstruct the list of the exquisite songs selected by Ishaq. In other words, the raison d’etre of the Aghānī is partly related to al-Isfahani's idol, Ishaq b. Ibrahim, and its information about singers, songs and performance owes a tremendous amount to him. Al-Isfahani's admiration for scholars or men of letters can be detected from time to time, usually in the passing comments in the chains of transmission. Yet al-Isfahani outspokenly expresses his admiration, in some cases, such as that of Ibn al-Muʿtazz (862–909). As an Umayyad by ancestry, al-Isfahani's later biographers mention his Shi'i affiliation with surprise. Yet, in the light of the history of the family's connections with the Abbasid elite of Shi'i inclination and the Ṭālibids, and of his learning experience in Kūfa, his Shi'i conviction is understandable. Al-Tusi (995–1067) is the only early source specifying the exact sect to which al-Isfahani belonged in the fluid Shi'i world: he was a Zaydī. Although al-Ṭūsī's view is widely accepted, its veracity is not beyond doubt. Al-Isfahani does not seem to have been informed of the latest Zaydī movements in Yemen and Ṭabaristān during his life, while his association with the Kūfan Zaydī community, which to some degree became less distinguishable from the Sunnīs, is yet to be studied in depth. It is clear, based on examination of how al-Isfahani amended the reports at his disposal, that he honoured Ali, who played a far more prominent role in his works than the first three caliphs, and some of his descendants, including Zaydi Shi'ism's eponym, Zayd ibn Ali (694–740), by presenting them positively, while, in some cases, leaving their enemies’ rectitude in question. In spite of that, al-Isfahani is neither keen to identify the imams in the past, nor discuss the qualities of an imam.{{efn|The Zaydī writings in the late ninth and early tenth centuries more or less devote discussion to the role and qualities of imam; see, for example: {{sfn|ref=Majmūʿ Rasāʾil|Yaḥyā, Majmūʿ Rasāʾil|p=431–432}} al-Ḥādī ilā al-Ḥaqq also singled out a line of the Zaydi imams up till his time in his Kitab al-Ahkam; see:}} As a matter of fact, he hardly uses the word, not even applying it to Zayd b. Ali. Furthermore, he does not unconditionally approve any Alid revolt and seems lukewarm towards the group he refers to as Zaydis. Taken together, al-Isfahani's Shi'i conviction is better characterised as moderate love for Ali without impugning the dignity of the caliphs before him. Legacy Al-Isfahani authored a number of works, but only a few survive. Three of them are preserved through quotations: al-Qiyan ("The Singing Girls Enslaved by Men"), al-Diyarat ("The Monasteries"), and Mujarrad al-aghani (“The Abridgement of the Book of Songs”). A fragment of the Mujarrad al-aghani is found in Ibn Abi Uṣaybi'a's ʿUyun al-anba' fi tabaqat al-atibbaʾ, which quotes a poem by the caliph, al-Maʾmūn (r. 813–833), which was arranged as a song by Mutayyam. The first two have been reconstructed and published by al-ʿAtiyya, who collected and collateed the passages from later works that quote from al-Isfahani. The former, al-Qiyān, is a collection of the biographies of the enslaved singing girls. In it, al-Isfahani provided the basic information about the biographical subjects, the men who enslaved them, and their interaction with poets, notables such as caliphs, and their admirers, with illustration of their poetic and/or musical talents. The latter, al-Diyārāt, provides information related to monasteries, with the indication of their geographical locations and, sometimes, history and topographical characteristics. However, it is questionable to what extent the reconstructed editions can represent the original texts, since the passages, which quote al-Isfahani as a source for the given subject and are thus included by the editor, seldom identify the titles of the works. Four works survive in manuscripts and have been edited and published: Maqātil al-Ṭālibīyīn ("The Ṭālibid Martyrs"), Kitab al-Aghani ("The Book of the Songs"), Adab al-ghuraba ("The Etiquettes of the Strangers"), and al-Ima al-shawair ("The Enslaved Women Who Composed Poetry"). As noted above, al-Isfahani's authorship of the Adab al-ghurabaʾ is disputed. The author, whoever he may have been, mentions in the preface his sufferings from the hardship of time and vicissitude of fate, and the solace which he seeks through the stories of bygone people. Hence, he collects in the Adab al-ghuraba the reports about the experiences of strangers; those away from their homes or their beloved ones. Some of the stories centre on the hardship which strangers, anonymous or not, encountered in their journey or exile, usually shown in the epigrams written on monuments, rocks, or walls. Others relate excursions to the monasteries for drinking. The al-Imāʾ al-shawāʿir was composed at the order of the vizier al-Muhallabī, al-Isfahani's patron, who demanded the collection of the reports about the enslaved women who composed poetry from the Umayyad to the Abbasid periods. Al-Isfahani confesses that he could not find any noteworthy poetess in the Umayyad period, because the people at that time were not impressed with verses featuring tenderness and softness. Thus, he only records the Abbasid poetesses, with mention of the relevant fine verses or the pleasant tales, and arranges them in chronological order. There are 31 sections, addressing 32 poetesses, most of which are short and usually begin with al-Isfahani's summary of the subject. The Maqātil al-Ṭālibīyīn is a historical-biographical compilation concerning the descendants of Abu Talib, who died by being killed, poisoned to death in a treacherous way, on the run from the rulers’ persecution, or confined until death. The Maqātil literature was rather common, particularly amongst Shi'is, before al-Isfahani and he used many works of this genre as sources for the Maqātil al-Ṭālibīyīn. Al-Isfahani does not explain the motivation behind this compilation nor mention to whom they were dedicated, but according to the preface of this work, he sets out as a condition to recount the reports about the Ṭālibids who were “praiseworthy in their conduct and rightly guided in their belief (maḥmūd al-ṭarīqa wa-sadīd al-madhhab)”. Like the al-Imāʾ, the work is structured in chronological order, beginning with the first Ṭālibī martyr, Jaʿfar b. Abī Ṭālib, and ends in the year of its compilation, August 925 (Jumādā I 313). For each biographical entry, al-Isfahani gives the full name, the lineage (sometimes adding the maternal side). Less often, he additionally gives the virtues and personal traits of the subject and other material he thinks noteworthy, for example the prophetic ḥadīth about, or transmitted by, the subject of the biography in question. Then, al-Isfahani gives the account of the death which, more often than not, constitutes the end of the entry. Sometimes poetry for or by the subject is attached. The Maqātil was used as a reliable source of information by many Shi'i and non-Shi'i compilers of the following centuries. The Kitab al-Aghani, al-Isfahanis best known work, is an immense compilation, including songs provided with musical indications (melodic modes and meters of songs), the biographies of poets and musicians of different periods in addition to historical material. As noted above, al-Isfahani embarks on compiling the Aghani first under the command of a patron, whom he calls ra'is (chief), to reconstruct the list of one hundred fine songs, selected by Ishaq b. Ibrahim. Due to an obscure report in Yaqut's Mu'jam, this raʾīs is often assumed to be Sayf al-Dawla al-Ḥamdānī (r. 945–967), but recent studies suggest that a more plausible candidate for the dedication of the Aghani is the vizier al-Muhallabī. The Aghani is divided into three parts: first, The Hundred Songs (al-mi'a al-ṣawt  al-mukhtara) and other song collections; second, the songs of the caliphs and of their children and grandchildren (aghani al-khulafa wa-awladihim wa-awlad awladihim); and third, al-Isfahanis selection of songs. The articles in each part are arranged based on different patterns, but it is mostly the song which introduces the articles on biographies or events. The Kitab al-Aghani is not the first book or collection of songs in Arabic, but it can be asserted that it is the most important one, for it "is a unique mine of information not only on hundreds of song texts with their modes and meters, but also on the lives of their poets and composers, and on the social context of music making in early Islam and at the courts of the caliphs in Damascus and Baghdad". Because of al-Isfahani's pedantic documentation of his sources, the Kitab al-Aghani can also be used to reconstruct earlier books of songs or biographical dictionaries on musicians that are otherwise lost. As for the works that did not survive, based on their contents, as implied by their titles, they can be divided into the following categories: The genealogical works: Nasab Bani Abd Shams ("The Genealogy of the Banu Abd Shams"), Jamharat al-nasab ("The Compendium of Genealogies"), Nasab Bani Shayban ("The Genealogy of the Banu Shayban"), and Nasab al-Mahaliba ("The Genealogy of the Muhallabids"), this last probably dedicated to his patron, the vizier al-Muhallabi. The reports about specified or unspecified topics, such as Kitab al-Khammarin wa-l-khammarat ("The Book of Tavern-Keepers, Male and Female"), Akhbar al-tufayliyin ("Reports about Party Crashers"), al-Akhbar wa-l-nawadir ("The Reports and Rare Tales"), and Ayyam al-arab ("The Battle-Days of the Arabs"), which mentions 1700 days of the pre-Islamic tribal battles and was in circulation only in Andalusia. The reports about music, musicians and singers: the aforementioned Manajib al-khisyan ("The Noble Eunuchs"), Akhbzr Jahza al-Barmaki ("The Reports concerning Jahza al-Barmaki"), al-Mamalik al-shu'ara ("The Slave Poets"), Adab al-samz ("The Etiquettes of Listening to Music"), and Risala fi 'ilal al-nagham ("The Treatise on the Rules of Tones"). There are two works, only mentioned by al-Tusi: Kitab ma nazala min al-Qur'an fi amir al-mu'minīn wa-ahl baytih 'alayhim al-salam ("The Book about the Qur'anic Verses Revealed regarding the Commander of the Faithful and the People of His Family, Peace upon Them") and Kitab fihi kalam Fatima alayha al-salam fi Fadak ("The Book concerning the Statements of Fāṭima, Peace upon Her, regarding Fadak"). Should the attribution of these two works to al-Isfahani be correct, together with the Maqatil al-Talibiyin, they reveal al-Isfahani's Shi'i partisanship. Works Al-Isfahani is best known as the author of Kitab al-Aghani ("The Book of Songs"), an encyclopaedia of over 20 volumes and editions. However, he additionally wrote poetry, an anthology of verses on the monasteries of Mesopotamia and Egypt, and a genealogical work.Kitāb al-Aġānī () 'Book of Songs', a collection of Arabic chants rich in information on Arab and Persian poets, singers and other musicians from the 7th to the 10th centuries of major cities such as Mecca, Damascus, Isfahan, Rey, Baghdād and Baṣrah. The Book of Songs contains details of the ancient Arab tribes and courtly life of the Umayyads and provides a complete overview of the Arab civilization from the pre-Islamic Jahiliyya era, up to his own time. Abu ‘l-Faraj employs the classical Arabic genealogical device, or isnad, (chain of transmission), to relate the biographical accounts of the authors and composers. Although originally the poems were put to music, the musical signs are no longer legible. Abu ‘l-Faraj spent in total 50 years creating this work, which remains an important historical source. The first printed edition, published in 1868, contained 20 volumes. In 1888 Rudolf Ernst Brünnow published a 21st volume being a collection of biographies not contained in the Bulāq edition, edited from manuscripts in the Royal Library of Munich.Maqātil aṭ-Ṭālibīyīn (}), Tālibid Fights, a collection of more than 200 biographies of the descendants of Abu Talib ibn Abd al-Muttalib, from the time of the Prophet Muhammad to the writing of the book in 925/6, who died in an unnatural way. As Abul-Faraj said in the foreword to his work, he included only those Tālibids who rebelled against the government and were killed, slaughtered, executed or poisoned, lived underground, fled or died in captivity. The work is a major source for the Umayyad and Abbāsid Alid uprisings and the main source for the Hashimite meeting that took place after the assassination of the Umayyad Caliph al-Walīd II in the village of al-Abwā' between Mecca and Medina. At this meeting, al-'Abdallah made the Hashimites pledge an oath of allegiance to his son Muhammad al-Nafs al-Zakiyya as the new Mahdi.

Amyl nitrite

Amyl nitrite is a chemical compound with the formula C5H11ONO. A variety of isomers are known, but they all feature an amyl group attached to the nitrite functional group. The alkyl group is unreactive and the chemical and biological properties are mainly due to the nitrite group. Like other alkyl nitrites, amyl nitrite is bioactive in mammals, being a vasodilator, which is the basis of its use as a prescription medicine. As an inhalant, it also has a psychoactive effect, which has led to its recreational use, with its smell being described as that of old socks or dirty feet. It is also referred to as banapple gas. It was first documented in 1844 and came into medical use in 1867. Uses Amyl nitrite is employed medically to treat heart diseases as well as angina. Amyl nitrite is sometimes used as an antidote for cyanide poisoning. It can act as an oxidant, to induce the formation of methemoglobin. Methemoglobin in turn can sequester cyanide as cyanomethemoglobin. Amyl nitrite is used as a cleaning agent and solvent in industrial and household applications. It replaced dichlorodifluoromethane, an industrial chemical universally banned in 1996 due to damage to the ozone layer, as a printed circuit board cleaner. Trace amounts are added to some perfumes. It is also used recreationally as an inhalant drug that induces a brief euphoric state, and when combined with other intoxicant stimulant drugs such as cocaine or MDMA, the euphoric state intensifies and is prolonged. Once some stimulative drugs wear off, a common side effect is a period of depression or anxiety, colloquially called a "come down"; amyl nitrite is sometimes used to combat these negative after-effects. This effect, combined with its dissociative effects, has led to its use as a recreational drug (see poppers). Nomenclature The term "amyl nitrite" encompasses several isomers. In older literature, the common non-systematic name amyl was often used for the pentyl group, where the amyl group is a linear or normal (n) alkyl group, and the resulting amyl nitrite would have the structural formula CH3(CH2)4ONO, also referred to as n-amyl nitrite. A common form of amyl nitrite is the isomer with the formula (CH3)2CHCH2CH2ONO, which may be more specifically referred to as isoamyl nitrite. The similarly named amyl nitrate has very different properties. At the same time, isopropyl nitrite has a similar structure and similar uses (also called 'poppers') but with worse side-effects. Synthesis and reactions Alkyl nitrites are prepared by the reaction of alcohols with nitrous acid: ROH + HONO → RONO + H2O, where R = alkyl group The reaction is called esterification. Synthesis of alkyl nitrites is, in general, straightforward and can be accomplished in home laboratories. A common procedure includes the dropwise addition of concentrated sulfuric acid to a cooled mixture of an aqueous sodium nitrite solution and an alcohol. The intermediately-formed stoichiometric mixture of nitrogen dioxide and nitric oxide then converts the alcohol to the alkyl nitrite, which, due to its low density, will form an upper layer that can be easily decanted from the reaction mixture. Isoamyl nitrite decomposes in the presence of base to give nitrite salts and the isoamyl alcohol: C5H11ONO + NaOH → C5H11OH + NaNO2 Amyl nitrite, like other alkyl nitrites, reacts with carbanions to give oximes. Amyl nitrites are also useful as reagents in a modification of the Sandmeyer reaction. The reaction of the alkyl nitrite with an aromatic amine in a halogenated solvent produces a radical aromatic species, this then frees a halogen atom from the solvent. For the synthesis of aryl iodides diiodomethane is used, whereas bromoform is the solvent of choice for the synthesis of aryl bromides. Physiological effects Amyl nitrite, in common with other alkyl nitrites, is a potent vasodilator; it expands blood vessels, resulting in lowering of the blood pressure. Amyl nitrite may be used during cardiovascular stress testing in patients with suspected hypertrophic cardiomyopathy to cause vasodilation and thereby reduce afterload and provoke obstruction of blood flow towards the aorta from the ventricle by increasing the pressure gradient, thereby causing left ventricular outflow obstruction. Alkyl nitrites are a source of nitric oxide, which signals for relaxation of the involuntary muscles. Physical effects include decrease in blood pressure, headache, flushing of the face, increased heart rate, dizziness, and relaxation of involuntary muscles, especially the blood vessel walls and the internal and external anal sphincter. There are no withdrawal symptoms. Overdose symptoms include nausea, vomiting, hypotension, hypoventilation, shortness of breath, and fainting. The effects set in very quickly, typically within a few seconds and disappear within a few minutes. Amyl nitrite may also intensify the experience of synesthesia. Amyl nitrite, when given as a medication for patients with angina, can also be administered as an ampule. The ampule is put in a gauze pad and then inhaled by the patient during an angina attack and repeated every fifteen minutes. However, oral dosing of amyl nitrite is ineffective due to poor absorption and extensive hepatic metabolism. Amyl nitrite has been widely replaced by nitroglycerin for the treatment of acute angina. Toxicity Although there are case reports of life-threatening toxicity involving unusually large amounts, typical inhaled doses of amyl nitrite are considered relatively safe. However, liquid amyl nitrite is highly toxic when ingested because of the unsafely high concentration it causes in blood. Regardless of the form or route of administration, acute toxicity principally results when the nitrite oxidizes a significant proportion of hemoglobin in the blood without oxygen, forming methemoglobin, which cannot carry oxygen. Severe poisoning cases will progress to methemoglobinemia, characterized by a blue-brown discoloration under the skin which could be mistaken for cyanosis. Treatment with oxygen and intravenous methylene blue frustrates visual confirmation further as methylene blue itself is, as its name suggests, a blue dye; the patient's changes in different shades of blue notwithstanding, it is an effective antidote by way of catalyzing the production of the enzyme responsible for reducing the methemoglobin in the blood back to hemoglobin. The discoloration does mean that regular near-infrared–based pulse oximetry becomes useless. More fundamentally, blood gas analysis on the whole has limited effectiveness, as the increased methemoglobin level increases the oxygen binding affinity of regular hemoglobin. Therefore, the measurement of actual ratios and levels of methemoglobin and hemoglobin must accompany any blood gas partial pressure sample in these cases. In popular culture Columbo episode titled "Troubled Waters" features amyl nitrite inhaled by the antagonist Hayden Danziger – played by Robert Vaughn – to help him feign a heart attack for his alibi. However, the episode consistently refers to the substance incorrectly as amyl nitrate. References Further reading Editorial on the use of the word "amyl".

Autumn

Autumn, also known as fall in North American English, is one of the four temperate seasons on Earth. Outside the tropics, autumn marks the transition from summer to winter, in September (Northern Hemisphere) or March (Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the Winter Solstice in December (Northern Hemisphere) and June (Southern Hemisphere). One of its main features in temperate climates is the striking change in colour for the leaves of deciduous trees as they prepare to shed. Date definitions Some cultures regard the autumnal equinox as "mid-autumn", while others with a longer temperature lag treat the equinox as the start of autumn. In the English-speaking world of high latitude countries, autumn traditionally began with Lammas Day and ended around Hallowe'en, the approximate mid-points between midsummer, the autumnal equinox, and midwinter. Meteorologists (and Australia and most of the temperate countries in the southern hemisphere) use a definition based on Gregorian calendar months, with autumn being September, October, and November in the northern hemisphere, and March, April, and May in the southern hemisphere. In the higher latitude countries in the Northern Hemisphere, autumn traditionally starts with the September equinox (21 to 24 September) and ends with the winter solstice (21 or 22 December). Popular culture in the United States associates Labor Day, the first Monday in September, as the end of summer and the start of autumn; certain summer traditions, such as wearing white, are discouraged after that date. As daytime and nighttime temperatures decrease, trees change colour and then shed their leaves. Persians celebrate the beginning of the autumn on Mehregan. Under the traditional East Asian solar term system, autumn starts on or around 8 August and ends on or about 7 November. In Ireland, the autumn months according to the national meteorological service, Met Éireann, are September, October, and November. However, according to the Irish Calendar, which is based on ancient Gaelic traditions, autumn lasts throughout the months of August, September, and October, or possibly a few days later, depending on tradition. In the Irish language, September is known as ("middle of autumn") and October as ("end of autumn"). Late Roman Republic scholar Marcus Terentius Varro defined autumn as lasting from the third day before the Ides of Sextilis (August 11) to the fifth day before the Ides of November (November 9). Etymology The word autumn () is derived from Latin autumnus, archaic auctumnus, possibly from the ancient Etruscan root autu- and has within it connotations of the passing of the year. Alternative etymologies include Proto-Indo-European ("cold") or ("dry"). After the Greek era, the word continued to be used as the Old French word ( in modern French) or in Middle English, and was later normalised to the original Latin. In the Medieval period, there are rare examples of its use as early as the 12th century, but by the 16th century, it was in common use. Before the 16th century, harvest was the term usually used to refer to the season, as it is common in other West Germanic languages to this day (cf. Dutch , German , and Scots ). However, as more people gradually moved from working the land to living in towns, the word harvest lost its reference to the time of year and came to refer only to the actual activity of reaping, and autumn, as well as fall, began to replace it as a reference to the season. The alternative word fall for the season traces its origins to old Germanic languages. The exact derivation is unclear, with the Old English or and the Old Norse all being possible candidates. However, these words all have the meaning "to fall from a height" and are clearly derived either from a common root or from each other. The term came to denote the season in 16th-century England, a contraction of Middle English expressions like "fall of the leaf" and "fall of the year". Compare the origin of spring from "spring of the leaf" and "spring of the year". During the 17th century, Englishmen began emigrating to the new North American colonies, and the settlers took the English language with them. While the term fall gradually became nearly obsolete in Britain, it became the more common term in North America. The name backend, a once common name for the season in Northern England, has today been largely replaced by the name autumn. Associations Harvest Association with the transition from warm to cold weather, and its related status as the season of the primary harvest, has dominated its themes and popular images. In Western cultures, personifications of autumn are usually pretty, well-fed females adorned with fruits, vegetables and grains that ripen at this time. Many cultures feature autumnal harvest festivals, often the most important on their calendars. Still-extant echoes of these celebrations are found in the autumn Thanksgiving holiday of the United States and Canada, and the Jewish Sukkot holiday with its roots as a full-moon harvest festival of "tabernacles" (living in outdoor huts around the time of harvest). There are also the many festivals celebrated by indigenous peoples of the Americas tied to the harvest of ripe foods gathered in the wild, the Chinese Mid-Autumn or Moon festival, and many others. The predominant mood of these autumnal celebrations is a gladness for the fruits of the earth mixed with a certain melancholy linked to the imminent arrival of harsh weather. This view is presented in English poet John Keats' poem To Autumn, where he describes the season as a time of bounteous fecundity, a time of 'mellow fruitfulness'. In North America, while most foods are harvested during the autumn, foods usually associated with the season include pumpkins (which are integral parts of both Thanksgiving and Halloween) and apples, which are used to make the seasonal beverage apple cider. Melancholia Autumn, especially in poetry, has often been associated with melancholia. The possibilities and opportunities of summer are gone, and the chill of winter is on the horizon. Skies turn grey, the amount of usable daylight drops rapidly, and many people turn inward, both physically and mentally. It has been referred to as an unhealthy season. Similar examples may be found in Irish poet W.B. Yeats' poem The Wild Swans at Coole where the maturing season that the poet observes symbolically represents his own ageing self. Like the natural world that he observes, he too has reached his prime and now must look forward to the inevitability of old age and death. French poet Paul Verlaine's "Chanson d'automne" ("Autumn Song") is likewise characterised by strong, painful feelings of sorrow. Keats' To Autumn, written in September 1819, echoes this sense of melancholic reflection but also emphasises the lush abundance of the season. The song "Autumn Leaves", based on the French song "Les Feuilles mortes", uses the melancholic atmosphere of the season and the end of summer as a metaphor for the mood of being separated from a loved one. Halloween Autumn is associated with Halloween (influenced by Samhain, a Celtic autumn festival), and with it a widespread marketing campaign that promotes it. The Celtic people also used this time to celebrate the harvest with a time of feasting. At the same time though, it was a celebration of death as well. Crops were harvested, livestock were butchered, and Winter was coming. Halloween, 31 October, is in autumn in the northern hemisphere. Television, film, book, costume, home decoration, and confectionery businesses use this time of year to promote products closely associated with such a holiday, with promotions going from late August or early September to 31 October, since their themes rapidly lose strength once the holiday ends, and advertising starts concentrating on Christmas. Other associations In some parts of the northern hemisphere, autumn has a strong association with the end of summer holiday and the start of a new school year, particularly for children in primary and secondary education. "Back to School" advertising and preparations usually occurs in the weeks leading to the beginning of autumn. Thanksgiving Day is a national holiday celebrated in Canada, in the United States, in some of the Caribbean islands and in Liberia. Thanksgiving is celebrated on the second Monday of October in Canada, on the fourth Thursday of November in the United States (where it is commonly regarded as the start of the Christmas and holiday season), and around the same part of the year in other places. Similarly named festival holidays occur in Germany and Japan. Television stations and networks, particularly in North America, traditionally begin their regular seasons in their autumn, with new series and new episodes of existing series debuting mostly during late September or early October (series that debut outside the autumn season are usually known as mid-season replacements). A sweeps period takes place in November to measure Nielsen Ratings. American football is played almost exclusively in the autumn months; at the high school level, seasons run from late August through early November, with some playoff games and holiday rivalry contests being played as late as Thanksgiving. In many American states, the championship games take place in early December. College football's regular season runs from September through November, while the main professional circuit, the National Football League, plays from September through to early January. Summer sports, such as association football (in Northern America, East Asia, Argentina, and South Africa), Canadian football, stock car racing, tennis, golf, cricket, and professional baseball, wrap up their seasons in early to late autumn; Major League Baseball's championship World Series is popularly known as the "Fall Classic". (Amateur baseball is usually finished by August.) Likewise, professional winter sports, such as ice hockey and basketball, and most leagues of association football in Europe, are in the early stages of their seasons during autumn; American college basketball and college ice hockey play teams outside their athletic conferences during the late autumn before their in-conference schedules begin in winter. The Christian religious holidays of All Saints' Day and All Souls' Day are observed in autumn in the Northern hemisphere. Easter falls in autumn in the southern hemisphere. The secular celebration of International Workers' Day also falls in autumn in the southern hemisphere. Since 1997, Autumn has been one of the top 100 names for girls in the United States. In Indian mythology, autumn is considered to be the preferred season for the goddess of learning Saraswati, who is also known by the name of "goddess of autumn" (Sharada). In Asian mysticism, Autumn is associated with the element of metal, and subsequently with the colour white, the White Tiger of the West, and death and mourning. Tourism Although colour change in leaves occurs wherever deciduous trees are found, coloured autumn foliage is noted in various regions of the world: most of North America, Eastern Asia (including China, Korea, and Japan), Europe, southeast, south, and part of the midwest of Brazil, the forest of Patagonia, eastern Australia and New Zealand's South Island. Eastern Canada and New England are famous for their autumnal foliage, and this attracts major tourism (worth billions of US dollars) for the regions.

Athlon

Athlon is the brand name applied to a series of x86-compatible microprocessors designed and manufactured by AMD. The original Athlon (now called Athlon Classic) was the first seventh-generation x86 processor and the first desktop processor to reach speeds of one gigahertz (GHz). It made its debut as AMD's high-end processor brand on June 23, 1999. Over the years AMD has used the Athlon name with the 64-bit Athlon 64 architecture, the Athlon II, and Accelerated Processing Unit (APU) chips targeting the Socket AM1 desktop SoC architecture, and Socket AM4 Zen microarchitecture. The modern Zen-based Athlon with a Radeon Graphics processor was introduced in 2019 as AMD's highest-performance entry-level processor. Athlon comes from the Ancient Greek (athlon), meaning "(sport) contest", or "prize of a contest", or "place of a contest; arena". With the Athlon name originally used for AMD's high-end processors, AMD currently uses Athlon for budget APUs with integrated graphics. AMD positions the Athlon against its rival, the Intel Pentium. Brand history K7 design and development The first Athlon processor was a result of AMD's development of K7 processors in the 1990s. AMD founder and then-CEO Jerry Sanders aggressively pursued strategic partnerships and engineering talent in the late 1990s, working to build on earlier successes in the PC market with the AMD K6 processor line. One major partnership announced in 1998 paired AMD with semiconductor giant Motorola to co-develop copper-based semiconductor technology, resulting in the K7 project being the first commercial processor to utilize copper fabrication technology. In the announcement, Sanders referred to the partnership as creating a "virtual gorilla" that would enable AMD to compete with Intel on fabrication capacity while limiting AMD's financial outlay for new facilities. The K7 design team was led by Dirk Meyer, who had previously worked as a lead engineer at DEC on multiple Alpha microprocessors. When DEC was sold to Compaq in 1998 and discontinued Alpha processor development, Sanders brought most of the Alpha design team to the K7 project. This added to the previously acquired NexGen K6 team, which already included engineers such as Vinod Dham. Original release The AMD Athlon processor launched on June 23, 1999, with general availability by August 1999. Subsequently, from August 1999 until January 2002, this initial K7 processor was the fastest x86 chip in the world. Wrote the Los Angeles Times on October 5, 1999: "AMD has historically trailed Intel’s fastest processors, but has overtaken the industry leader with the new Athlon. Analysts say the Athlon, which will be used by Compaq, IBM and other manufacturers in their most powerful PCs, is significantly faster than Intel’s flagship Pentium III, which runs at a top speed of 600MHz." A number of features helped the chips compete with Intel. By working with Motorola, AMD had been able to refine copper interconnect manufacturing about one year before Intel, with the revised process permitting 180-nanometer processor production. The accompanying die-shrink resulted in lower power consumption, permitting AMD to increase Athlon clock speeds to the 1 GHz range. The Athlon architecture also used the EV6 bus licensed from DEC as its main system bus, allowing AMD to develop its own products without needing to license Intel's GTL+ bus. By the summer of 2000, AMD was shipping Athlons at high volume, and the chips were being used in systems by Gateway, Hewlett-Packard, and Fujitsu Siemens Computers among others. Later Athlon iterations The second-generation Athlon, the Thunderbird, debuted in 2000. AMD released the Athlon XP the following year, and the Athlon XP's immediate successor, the Athlon 64, was an AMD64-architecture microprocessor released in 2003. After the 2007 launch of the Phenom processors, the Athlon name was also used for mid-range processors, positioned above brands such as Sempron. The Athlon 64 X2 was released in 2005 as the first native dual-core desktop CPU designed by AMD, and the Athlon X2 was a subsequent family based on the Athlon 64 X2. Introduced in 2009, Athlon II was a dual-core family of Athlon chips. A USD$55 low-power Athlon 200GE with a Radeon graphics processor was introduced in September 2018, sitting under the Ryzen 3 2200G. This iteration of Athlon used AMD's Zen-based Raven Ridge core, which in turn had debuted in Ryzen with Radeon graphics processors. With the release, AMD began using the Athlon brand name to refer to "low-cost, high-volume products", in a situation similar to both Intel's Celeron and Pentium Gold. The modern Athlon 3000G was introduced in 2019 and was positioned as AMD's highest-performance entry-level processor. AMD positions the Athlon against its rival, the Intel Pentium. While CPU processing performance is in the same ballpark, the Athlon 3000G uses Radeon Vega graphics, which are rated as more powerful than the Pentium's Intel UHD Graphics. Generations Athlon Classic (1999) The AMD Athlon processor launched on June 23, 1999, with general availability by August 1999. Subsequently, from August 1999 until January 2002, this initial K7 processor was the fastest x86 chip in the world. At launch it was, on average, 10% faster than the Pentium III at the same clock for business applications and 20% faster for gaming workloads. In commercial terms, the Athlon "Classic" was an enormous success. Features The Athlon Classic is a cartridge-based processor, named Slot A and similar to Intel's cartridge Slot 1 used for Pentium II and Pentium III. It used the same, commonly available, physical 242-pin connector used by Intel Slot 1 processors but rotated by 180 degrees to connect the processor to the motherboard. The cartridge assembly allowed the use of higher-speed cache memory modules than could be put on (or reasonably bundled with) motherboards at the time. Similar to the Pentium II and the Katmai-based Pentium III, the Athlon Classic contained 512 KB of L2 cache. This high-speed SRAM cache was run at a divisor of the processor clock and was accessed via its own 64-bit back-side bus, allowing the processor to service both front-side bus requests and cache accesses simultaneously, as compared to pushing everything through the front-side bus. The Argon-based Athlon contained 22 million transistors and measured 184 mm2. It was fabricated by AMD in a version of their CS44E process, a 250 nm complementary metal–oxide–semiconductor (CMOS) process with six levels of aluminium interconnect. "Pluto" and "Orion" Athlons were fabricated in a 180 nm process. The Athlon's CPU cache consisted of the typical two levels. Athlon was the first x86 processor with a 128 KB split level-1 cache; a 2-way associative cache separated into 2×64 KB for data and instructions (a concept from Harvard architecture). SRAM cache designs at the time were incapable of keeping up with the Athlon's clock scalability, resulting in compromised CPU performance in some computers. With later Athlon models, AMD would integrate the L2 cache onto the processor itself, removing dependence on external cache chips. The Slot-A Athlons were the first multiplier-locked CPUs from AMD, preventing users from setting their own desired clock speed. This was done by AMD in part to hinder CPU remarking and overclocking by resellers, which could result in inconsistent performance. Eventually a product called the "Goldfingers device" was created that could unlock the CPU. AMD designed the CPU with more robust x86 instruction decoding capabilities than that of K6, to enhance its ability to keep more data in-flight at once. The critical branch-predictor unit was enhanced compared to the K6. Deeper pipelining with more stages allowed higher clock speeds to be attained. Like the AMD K5 and K6, the Athlon dynamically buffered internal micro-instructions at runtime resulting from parallel x86 instruction decoding. The CPU is an out-of-order design, again like previous post-5x86 AMD CPUs. The Athlon utilizes the Alpha 21264's EV6 bus architecture with double data rate (DDR) technology. AMD ended its long-time handicap with floating point x87 performance by designing a super-pipelined, out-of-order, triple-issue floating-point unit (FPU). Each of its three units could independently calculate an optimal type of instructions with some redundancy, making it possible to operate on more than one floating-point instruction at once. This FPU was a huge step forward for AMD, helping compete with Intel's P6 FPU. The 3DNow! floating-point SIMD technology, again present, received some revisions and was renamed "Enhanced 3DNow!" Additions included DSP instructions and the extended MMX subset of Intel SSE. Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 512 KB, external chips on CPU module with 50%, 40% or 33% of CPU speed MMX, 3DNow! Slot A (EV6) Front-side bus: 200 MT/s (100 MHz double-pumped) Vcore: 1.6 V (K7), 1.6–1.8 V (K75) First release: June 23, 1999 (K7), November 29, 1999 (K75) Clock-rate: 500–700 MHz (K7), 550–1000 MHz (K75) Athlon Thunderbird (2000–2001) The second-generation Athlon, the Thunderbird or T-Bird, debuted on June 4, 2000. This version of the Athlon was available in a traditional pin-grid array (PGA) format that plugged into a socket ("Socket A") on the motherboard, or packaged as a Slot A cartridge. The major difference between it and the Athlon Classic was cache design, with AMD adding in 256 KB of on-chip, full-speed exclusive cache. In moving to an exclusive cache design, the L1 cache's contents were not duplicated in the L2, increasing total cache size and functionally creating a large L1 cache with a slower region (the L2) and a fast region (the L1), making the L2 cache into basically a victim cache. With the new cache design, need for high L2 performance and size was lessened, and the simpler L2 cache was less likely to cause clock scaling and yield issues. Thunderbird also moved to a 16-way associative layout. The Thunderbird was "cherished by many for its overclockability" and proved commercially successful, as AMD's most successful product since the Am386DX-40 ten years earlier. AMD's new fab facility in Dresden increased production for AMD overall and put out Thunderbirds at a fast rate, with the process technology improved by a switch to copper interconnects. After several versions were released in 2000 and 2001 of the Thunderbird, the last Athlon processor using the Thunderbird core was released in 2001 in the summer, at which point speeds were at 1.4 GHz. The locked multipliers of Socket A Thunderbirds could often be disabled through adding conductive bridges on the surface on the chip, a practice widely known as "the pencil trick". Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 256 KB, full speed MMX, 3DNow! Slot A & Socket A (EV6) Front-side bus: 100 MHz (Slot-A, B-models), 133 MHz (C-models) (200 MT/s, 266 MT/s) Vcore: 1.70–1.75 V First release: June 4, 2000 Transistor count: 37 million Manufacturing process: /180 nm Clock rate: Slot A: 650–1000 MHz Socket A, 100 MHz FSB (B-models): 600–1400 MHz Socket A, 133 MHz FSB (C-models): 1000–1400 MHz Athlon XP (2001–2003) Overall, there are four main variants of the Athlon XP desktop CPU: the Palomino, the Thoroughbred, the Thorton, and the Barton. A number of mobile processors were also released, including the Corvette models, and the Dublin model among others. Palomino On May 14, 2001, AMD released the Athlon XP processor. It debuted as the Mobile Athlon 4, a mobile version codenamed Corvette, with the desktop Athlon XP released in the fall. The third-generation Athlon, code-named Palomino, came out on October 9, 2001, as the Athlon XP, with the suffix signifying extreme performance and unofficially referencing Windows XP. Palomino's design used 180 nm fabrication process size. The Athlon XP was marketed using a performance rating (PR) system comparing it to the Thunderbird predecessor core. Among other changes, Palomino consumed 20% less power than the Thunderbird, comparatively reducing heat output, and was roughly 10% faster than Thunderbird. Palomino also had enhanced K7's TLB architecture and included a hardware data prefetch mechanism to take better advantage of memory bandwidth. Palomino was the first K7 core to include the full SSE instruction set from the Intel Pentium III, as well as AMD's 3DNow! Professional. Palomino was also the first socketed Athlon officially supporting dual processing, with chips certified for that purpose branded as the Athlon MP (multi processing), which had different specifications. According to HardwareZone, it was possible to modify the Athlon XP to function as an MP. Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 256 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 133 MHz (266 MT/s) Vcore: 1.50 to 1.75 V Power consumption: 68 W First release: October 9, 2001 Clock-rate: Athlon 4: 850–1400 MHz Athlon XP: 1333–1733 MHz (1500+ to 2100+) Athlon MP: 1000–1733 MHz Thoroughbred The fourth-generation of Athlon was introduced with the Thoroughbred core, or T-Bred, on April 17, 2002. The Thoroughbred core marked AMD's first production 130 nm silicon, with smaller die size than its predecessor. There came to be two steppings (revisions) of this core commonly referred to as Tbred-A and Tbred-B. Introduced in June 2002, the initial A version was mostly a direct die shrink of the preceding Palomino core, but did not significantly increase clock speeds over the Palomino. A revised Thoroughbred core, Thoroughbred-B, added a ninth "metal layer" to the eight-layered Thoroughbred-A, offering improvement in headroom over the A and making it popular for overclocking. Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 256 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 133/166 MHz (266/333 MT/s) Vcore: 1.50–1.65 V First release: June 10, 2002 (A), August 21, 2002 (B) Clock-rate: Thoroughbred "A": 1400–1800 MHz (1600+ to 2200+) Thoroughbred "B": 1400–2250 MHz (1600+ to 2800+) 133 MHz FSB: 1400–2133 MHz (1600+ to 2600+) 166 MHz FSB: 2083–2250 MHz (2600+ to 2800+) Barton / Thorton Fifth-generation Athlon Barton-core processors were released in early 2003. While not operating at higher clock rates than Thoroughbred-core processors, they featured an increased L2 cache, and later models had an increased 200 MHz (400 MT/s) front side bus. The Thorton core, a blend of thoroughbred and Barton, was a later variant of the Barton with half of the L2 cache disabled. The Barton was used to officially introduce a higher 400 MT/s bus clock for the Socket A platform, which was used to gain some Barton models more efficiency. By this point with the Barton, the four-year-old Athlon EV6 bus architecture had scaled to its limit and required a redesign to exceed the performance of newer Intel processors. By 2003, the Pentium 4 had become more than competitive with AMD's processors, and Barton only saw a small performance increase over the Thoroughbred-B it derived from, insufficient to outperform the Pentium 4. The K7-derived Athlons such as Barton were replaced in September 2003 by the Athlon 64 family, which featured an on-chip memory controller and a new HyperTransport bus. Notably, the 2500+ Barton with 11× multiplier was effectively identical to the 3200+ part other than the FSB speed it was binned for, meaning that seamless overclocking was possible more often than not. Early Thortons could be restored to the full Barton specification with the enabling of the other half of the L2 cache from a slight CPU surface modification, but the result was not always reliable. Specifications Barton (130 nm) L1-cache: 64 + 64 KB (data + instructions) L2-cache: 512 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 166/200 MHz (333/400 MT/s) Vcore: 1.65 V First release: February 10, 2003 Clock rate: 1833–2333 MHz (2500+ to 3200+) 133 MHz FSB: 1867–2133 MHz (2500+ to 2800+); uncommon 166 MHz FSB: 1833–2333 MHz (2500+ to 3200+) 200 MHz FSB: 2100, 2200 MHz (3000+, 3200+) Thorton (130 nm) L1-cache: 64 + 64 KB (Data + Instructions) L2-cache: 256 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 133/166/200 MHz (266/333/400 MT/s) Vcore: 1.50–1.65 V First release: September 2003 Clock rate: 1667–2200 MHz (2000+ to 3100+) 133 MHz FSB: 1600–2133 MHz (2000+ to 2600+) 166 MHz FSB: 2083 MHz (2600+) 200 MHz FSB: 2200 MHz (3100+) Mobile Athlon XP The Palomino core debuted in the mobile market before the PC market in May 2001, where it was branded as Mobile Athlon 4 with the codename "Corvette". It distinctively used a ceramic interposer much like the Thunderbird instead of the organic pin grid array package used on all later Palomino processors. In November 2001, AMD released a 1.2 GHz Athlon 4 and a 950 MHz Duron. The Mobile Athlon 4 processors included the PowerNow! function, which controlled a laptop's "level of processor performance by dynamically adjusting its operating frequency and voltage according to the task at hand", thus extending "battery life by reducing processor power when it isn't needed by applications". Duron chips also included PowerNow! In 2002, AMD released a version of PowerNow! called Cool'n'Quiet, implemented on the Athlon XP but only adjusting clock speed instead of voltage. In 2002 the Athlon XP-M (Mobile Athlon XP) replaced the Mobile Athlon 4 using the newer Thoroughbred core, with Barton cores for full-size notebooks. The Athlon XP-M was also offered in a compact microPGA socket 563 version. Mobile XPs were not multiplier-locked, making them popular with desktop overclockers. Athlon 64 (2003–2009) The immediate successor to the Athlon XP, the Athlon 64 is an AMD64-architecture microprocessor produced by AMD, released on September 23, 2003. A number of variations, all named after cities, were released with 90 nm architecture in 2004 and 2005. Versions released in 2007 and 2009 utilized 65 nm architecture. Athlon 64 X2 (2005–2009) The Athlon 64 X2 was released in 2005 as the first native dual-core desktop CPU designed by AMD using an Athlon 64. The Athlon X2 was a subsequent family of microprocessors based on the Athlon 64 X2. The original Brisbane Athlon X2 models used 65 nm architecture and were released in 2007. Athlon II (2009–2012) Athlon II is a family of central processing units. Initially a dual-core version of the Athlon II, the K-10-based Regor was released in June 2009 with 45-nanometer architecture. This was followed by a single-core version Sargas, followed by the quad-core Propus, the triple-core Rana in November 2009, and the Llano 32 nm version released in 2011. Bristol-Ridge-based Athlon X4 (2017) Main Article: Athlon X4 "Bristol Ridge" (2017, 28 nm) The Bristol Ridge Athlon X4 lineup was released in 2017. It was based on the Excavator microarchitecture and used 2 Excavator modules tolalling 4 "cores". It had a dual-channel DDR4-2400 memory controller with clockspeeds up to 4.0GHz. It ran on the new Socket AM4 platform that was being used for Zen1-3 CPU's. Zen-based Athlon (2018–present) The Zen-based Athlon with Radeon graphics processors was launched in September 2018 with the Athlon 200GE. Based on AMD's Raven Ridge core previously used in variants of the Ryzen 3 and Ryzen 5, the Athlon 200GE had half of the cores but left SMT enabled. It also kept the same 4 MiB L3 cache, but the L2 cache was halved to 1 MiB. In addition, the number of graphics compute units was limited to 3 in the Athlon 200GE, and the chip was multiplier-locked. Despite its limitations, the Athlon 200GE performed competitively against the 5000-series Intel Pentium-G, displaying similar CPU performance but an advantage in GPU performance. On November 19, 2019, AMD released the Athlon 3000G, with a higher 3.5 GHz core clock and 1100 MHz graphics clock compared to the Athlon 200GE, also with two cores. The main functional difference between the 200GE was the Athlon 3000G's unlocked multiplier, allowing the latter to be overclocked on B450 and X470 motherboards. Specifications Raven Ridge (14 nm), Picasso (12 nm) (see the list article for more details) L1 cache: 192 KiB (2×64 KiB + 2×32 KiB) L2 cache: 1 MiB (2×512 KiB) L3 cache: 4 MiB Memory: dual-channel DDR4-2666, 64 GiB max.

Albert Brooks

Albert Brooks (born Albert Lawrence Einstein ; July 22, 1947) is an American actor, comedian, director and screenwriter. He received an Academy Award nomination for Best Supporting Actor for 1987's Broadcast News and was widely praised for his performance in the 2011 action drama film Drive. Brooks has also acted in Taxi Driver (1976), Private Benjamin (1980), Unfaithfully Yours (1984), and My First Mister (2001). He has written, directed, and starred in several comedy films, such as Modern Romance (1981), Lost in America (1985), and Defending Your Life (1991). He is also the author of 2030: The Real Story of What Happens to America (2011). His voice acting credits include Marlin in Finding Nemo (2003) and Finding Dory (2016), Tiberius in The Secret Life of Pets (2016), and several one-time characters in The Simpsons, including Hank Scorpio in "You Only Move Twice" (1996) and Russ Cargill in The Simpsons Movie (2007). Early life Brooks was born Albert Lawrence Einstein on July 22, 1947 into a Jewish show business family in Beverly Hills, California, to Thelma Leeds (née Goodman), an actress, and Harry Einstein, a radio comedian who performed on Eddie Cantor's radio program and was known as "Parkyakarkus". He is the youngest of three sons. His older brothers are the late comedic actor Bob Einstein (1942–2019), and Clifford Einstein (b. 1939), a partner and longtime chief creative officer at Los Angeles advertising agency Dailey & Associates. His older half-brother was Charles Einstein (1926–2007), a writer for such television programs as Playhouse 90 and Lou Grant. His grandparents emigrated from Austria and Russia. He grew up among show business families in southern California, attending Beverly Hills High School with Richard Dreyfuss and Rob Reiner. Career Early career Brooks attended Carnegie Mellon University in Pittsburgh (where his classmates included Michael McKean and David L. Lander), but dropped out after one year to focus on his comedy career. By the age of 19, he had changed his professional name to Albert Brooks, joking that "the real Albert Einstein changed his name to sound more intelligent". He quickly became a regular on variety and talk shows during the late 1960s and early 1970s, and was on the writing staff for the ill-fated ABC show Turn-On, which was cancelled after one episode. In 1970-71, he also worked with college friends McKean and Lander (alongside Harry Shearer) as a writer/guest performer on some early material by radio and LP record comedy group The Credibility Gap. Brooks led a new generation of self-reflective baby-boomer comics appearing on NBC's The Tonight Show Starring Johnny Carson. His on-stage persona, that of an egotistical, narcissistic, nervous comic, an ironic showbiz insider who punctured himself before an audience by disassembling his mastery of comedic stagecraft, influenced other '70s post-modern comedians, including Steve Martin, Martin Mull, and Andy Kaufman. After two successful comedy albums, Comedy Minus One (1973) and the Grammy Award–nominated A Star Is Bought (1975), Brooks left the stand-up circuit to try his hand as a filmmaker. He had already made his first short film, The Famous Comedians School, a satiric short and an early example of the mockumentary subgenre that was aired in 1972 on the PBS show The Great American Dream Machine. In 1975, Brooks directed six short films for the first season of NBC's Saturday Night Live. In 1976, he appeared in his first mainstream film role, in Martin Scorsese's landmark Taxi Driver; Scorsese allowed Brooks to improvise much of his dialogue. Brooks had landed the role after moving to Los Angeles to enter the film business. Brooks directed his first feature film, Real Life, in 1979, which he co-wrote with Harry Shearer. The film, in which Brooks (playing a version of himself) films a typical suburban family in an effort to win both an Oscar and a Nobel Prize, was a sendup of PBS's An American Family documentary. It has also been viewed as foretelling the future emergence of reality television. Brooks also appeared in the film Private Benjamin (1980), starring Goldie Hawn. 1981–1999 Through the 1980s and 1990s, Brooks co-wrote (with long-time collaborator Monica Johnson), directed and starred in a series of well-received comedies, playing variants on his standard neurotic and self-obsessed character. These include 1981's Modern Romance, where Brooks played a film editor desperate to win back his ex-girlfriend (Kathryn Harrold). The film received a limited release and ultimately grossed under $3 million domestically. His best-received film, Lost in America (1985), featured Brooks and Julie Hagerty as a couple who leave their yuppie lifestyle and drop out of society to live in a motor home as they have always dreamed of doing, meeting disappointment. Brooks' Defending Your Life (1991) placed his lead character in the afterlife, put on trial to justify his human fears and determine his cosmic fate. Critics responded to the off-beat premise and the chemistry between Brooks and Meryl Streep, as his post-death love interest. His later efforts did not find large audiences, but still retained Brooks' touch as a filmmaker. He garnered positive reviews for Mother (1996), which starred Brooks as a middle-aged writer moving back home to resolve tensions between himself and his mother (Debbie Reynolds). 1999's The Muse featured Brooks as a Hollywood screenwriter who has "lost his edge", using the services of an authentic muse (Sharon Stone) for inspiration. In an interview with Brooks with regards to The Muse, Gavin Smith wrote, "Brooks's distinctive film making style is remarkably discreet and unemphatic; he has a light, deft touch, with a classical precision and economy, shooting and cutting his scenes in smooth, seamless successions of medium shots, with clean, high-key lighting." Brooks has appeared as a guest voice on The Simpsons seven times during its run (always under the name A. Brooks). He is described as the best guest star in the show's history by IGN, particularly for his role as supervillain Hank Scorpio in the episode "You Only Move Twice". Brooks also acted in other writers' and directors' films during the 1980s and 1990s. He had a cameo in the opening scene of Twilight Zone: The Movie, playing a driver whose passenger (Dan Aykroyd) has a shocking secret. In James L. Brooks's hit Broadcast News (1987), Albert Brooks was nominated for an Academy Award for Best Supporting Actor for playing an insecure, supremely ethical network TV reporter, who offers the rhetorical question, "Wouldn't this be a great world if insecurity and desperation made us more attractive?" He also won positive notices for his role in 1998's Out of Sight, playing an untrustworthy banker and ex-convict. 2000–present Brooks received positive reviews for his portrayal of a dying retail store owner who befriends a disillusioned teenager (played by Leelee Sobieski) in My First Mister (2001). Brooks continued his voiceover work in Pixar's Finding Nemo (2003), as the voice of Marlin, one of the film's protagonists. In 2005, his film Looking for Comedy in the Muslim World was dropped by Sony Pictures due to their desire to change the title. Warner Independent Pictures purchased the film and gave it a limited release in January 2006; the film received mixed reviews and a low box office gross. As with Real Life, Brooks plays a fictionalized "Albert Brooks", a filmmaker ostensibly commissioned by the U.S. government to see what makes the Muslim people laugh, and sending him on a tour of India and Pakistan. In 2006 he appeared in the documentary film Wanderlust as David Howard from Lost in America. In 2007, he continued his long-term collaboration with The Simpsons by voicing Russ Cargill, the central antagonist of The Simpsons Movie. He has played Lenny Botwin, Nancy Botwin's estranged father-in-law, on Showtime's television series Weeds. St. Martin's Press published his first novel, 2030: The Real Story of What Happens to America, on May 10, 2011. In 2011, Brooks co-starred as the vicious gangster Bernie Rose, the main antagonist in the film Drive, alongside Ryan Gosling and Carey Mulligan. His performance received much critical praise and positive reviews. After receiving awards and nominations from several film festivals and critic groups, but not an Academy Award nomination, Brooks responded humorously on Twitter, "And to the Academy: ‘You don't like me. You really don't like me’." In 2016, Brooks voiced Tiberius, a curmudgeonly red-tailed hawk, in The Secret Life of Pets, and reprised the role of Marlin from Finding Nemo in the 2016 sequel Finding Dory. Personal life In 1997, Brooks married artist Kimberly Shlain, daughter of surgeon and writer Leonard Shlain. They have two children, Jacob and Claire.

Australian Broadcasting Corporation

The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the Australian Broadcasting Corporation Act 1983. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a television licence, the ABC was originally financed by consumer licence fees on broadcast receivers. Licence fees were abolished in 1973 and replaced by direct government grants, as well as revenue from commercial activities related to its core broadcasting mission. The ABC adopted its current name in 1983. The ABC provides radio, television, online, and mobile services throughout metropolitan and regional Australia. ABC Radio operates four national networks, a large number of ABC Local Radio stations, several digital stations, and the international service Radio Australia. ABC Television operates five free-to-air channels, as well as the ABC iview streaming service and the ABC Australia satellite channel. News and current affairs content across all platforms is produced by the news division. The postal address of the ABC in every Australian capital city is PO Box 9994, as a tribute to the record-breaking batting average of Australian cricketer Sir Donald Bradman. History Origins After public radio stations were established independently in the state capitals from 1924, a licensing scheme administered by the Postmaster-General's Department was established, allowing certain stations (with "Class A" licences") government funding, albeit with restrictions placed on their advertising content. In 1928, the government established the National Broadcasting Service to take over the 12 A-Class licences as they came up for renewal, and contracted the Australian Broadcasting Company, a private company established in 1924, to supply programs to the new national broadcaster. After it became politically unpopular to continue to allow the Postmaster-General to run the National Broadcasting Service, the government established the Australian Broadcasting Commission (ABC) on 1 July 1932, under the Australian Broadcasting Commission Act 1932. to take over the Australian Broadcasting Company and run the National Broadcasting Service. The ABC became informally referred to as "Aunty", originally in imitation of the British Broadcasting Corporation's nickname. The structure and programming was broadly modelled on the BBC, and programs not created in Australia were mostly bought in from the BBC. In 1940 one of the ABC Board's most prominent members, Dick Boyer, was appointed to the ABC, becoming chairman on 1 April 1945. Today known for the continuing series of Boyer Lectures initiated by him in 1959, he had a good but not too close working relationship with Sir Charles Moses (general manager 1935–1965), and remained chair until his retirement in 1961. He was determined to maintain the autonomy of the ABC. War years In 1942, The Australian Broadcasting Act was passed, giving the ABC the power to decide when, and in what circumstances, political speeches should be broadcast. Directions from the minister about whether or not to broadcast any matter now had to be made in writing, and any exercise of the power had to be mentioned in the commission's annual report. 1950–2000 The ABC commenced television broadcasting in 1956. ABN-2 in Sydney was inaugurated by Prime Minister Robert Menzies on 5 November 1956, with the first broadcast presented by Michael Charlton, and James Dibble reading the first television news bulletin. Television relay facilities were not in place until the early 1960s, so news bulletins had to be sent to each capital city by teleprinter, to be prepared and presented separately in each city. In 1975, colour television was permanently introduced into Australia, and within a decade, the ABC had moved into satellite broadcasting, greatly enhancing its ability to distribute content nationally. Also in 1975, the ABC introduced a 24-hour-a-day AM rock station in Sydney, 2JJ (Double Jay), which was eventually expanded into the national Triple J FM network. A year later, a national classical music network was established on the FM band, broadcasting from Adelaide. It was initially known as ABC-FM (later ABC Classic FM) – referring both to its "fine music programming and radio frequency. ABC budget cuts began in 1976 and continued until 1998, the largest cuts (calculated by the ABC as 25% "in real terms") coming between 1985 and 1996. The Australian Broadcasting Corporation Act 1983 changed the name of the organisation to the Australian Broadcasting Corporation, effective 1 July 1983. Although funded and owned by the government, the ABC remains editorially independent as ensured by the 1983 Act. At the same time, the newly formed corporation underwent significant restructuring, including a split into separate television and radio divisions, and ABC Radio was restructured significantly again in 1985. Geoffrey Whitehead was managing director of the ABC at this time. Following his resignation in 1986, David Hill (at the time chair of the ABC Board) took over his position and local production trebled from 1986 to 1991. Live television broadcasts of selected parliamentary sessions started in 1990, and by the early 1990s, all major ABC broadcasting outlets moved to 24-hour-a-day operation. In 1991, the corporation's Sydney radio and orchestral operations moved to a new building, the ABC Ultimo Centre, in the inner-city suburb of Ultimo. In Melbourne, the ABC Southbank Centre was completed in 1994. International television service ABC Australia was established in 1993, while at the same time Radio Australia increased its international reach. Reduced funding in 1997 for Radio Australia resulted in staff and programming cuts. The ABC Multimedia Unit was established in July 1995 to manage the new ABC website, which was launched in August. The ABC was registered on the Australian Business Register as a Commonwealth Government Entity on 1 November 1999. 2000s–2010s In 2001, digital television commenced (see Online, below). At the same time, the ABC's multimedia division was renamed "ABC New Media", becoming an output division of the ABC alongside television and radio. In 2002, the ABC launched ABC Asia Pacific, the replacement for the defunct Australia Television International operated previously by the Seven Network. A digital radio service, ABC DiG, was also launched in November that year. On 8 February 2008, ABC TV was rebranded as ABC1, and a new channel for children, ABC3, was funded and announced by the Rudd government in June. A new online video-on-demand service launched in July of the same year, titled ABC iview. ABC News 24, now known as ABC News, a channel dedicated to news, launched on 22nd July 2010. On 20 July 2014, ABC1 reverted to its original name of ABC TV. In November 2014, a cut of (4.6% ) to funding over the following five years together with the additional unfunded cost of the news channel meant that the ABC would have to shed about 10% of its staff, around 400 people. There were several programming changes, with regional and local programming losing out to national programs, and the Adelaide TV production studio had to close. In November 2016, the ABC announced that ABC News 24, ABC NewsRadio, as well as its online and digital news brands, would be rebranded under a unified ABC News brand, which was launched on 10 April 2017. Michelle Guthrie took over from managing director Mark Scott, whose second five-year contract finished in April 2016. Between July 2017 and June 2018, the whole of the ABC underwent an organisational restructure, after which the Radio and Television Divisions were no longer separate entities each under a director, instead being split across several functional divisions, with different teams producing different genres of content for television, radio and digital platforms. The Entertainment & Specialist (E&S) team focussed on comedy, kids' programs, drama, Indigenous-related programs, music, other entertainment and factual content; the new ABC Specialist team created content across the arts, science, religion & ethics, education and society & culture; while the Regional & Local team focussed on regional and local content. Around 23 September 2018, Guthrie was sacked. A leadership crisis ensued after allegations arose that ABC Chair, Justin Milne, had, according to the MEAA, engaged in "overt political interference in the running of the ABC that is in clear breach of the ABC charter and the role of the chairperson" by interfering in editorial and staffing matters. After pressure for an independent inquiry or statement from Milne, or his resignation, following meetings by ABC staff in various locations, on 27 September Milne resigned. In February 2019, after the roles of ABC chair and managing director had been vacant for over four months, Ita Buttrose was named chair. Buttrose named David Anderson as managing director in May 2019. On 5 June 2019, Australian Federal Police (AFP) raided the headquarters of the ABC looking for articles written in 2017 about alleged misconduct by Australian special forces in Afghanistan, later dubbed the Afghan Files. The raid was countered by lawyers for the ABC in litigation against the AFP, challenging the examination of over 9,200 documents, including internal emails. In February 2020 the case was dismissed by the federal court. In June 2020, the AFP sent a brief of evidence to the Commonwealth Director of Public Prosecutions (CDPP), the federal public prosecutor, recommending charges be laid against journalist Dan Oakes for breaking the Afghan Files story, but in October 2020, the CDPP dropped the case. 2020s In June 2020, the ABC announced it needed to cut 229 jobs, a number of programs, and reduce its travel and production budgets after the Turnbull government's announcement of a freeze to indexation of its budget in 2018 this was estimated at the time to cost the ABC over three years, however the actual appropriation did not decrease and the ABC chair was quoted as saying it would actually increase "but by a reduced amount". In all, over a five-year period, there were 737 redundancies, a further 866 resignations and 203 retirements, but the total number of staff only fell by 313 due to the ABC hiring 650 staff over that period. In June 2021, the ABC announced its plan to move around 300 staff to offices in Parramatta, in a plan which would see 75% of journalists and producers moving out of the Ultimo building by 2025 in order to reduce costs. Rental from some of the vacant space in the city centre would earn additional income to offset the ongoing effects of the significant funding cuts since 2014 and the recent indexation freeze. In December 2021 the ABC announced that, in addition to the 83 additional positions already established, it was to create an additional "50-plus" new jobs in regional Australia as a result of commercial agreements with digital platforms flowing from the Morrison government's News Media Bargaining Code. Lissajous curve logo The ABC logo is one of the most recognisable logos in Australia. In the early years of television, the ABC had been using Lissajous curves as fillers between programmes. In July 1963, the ABC conducted a staff competition to create a new logo for use on television, stationery, publications, microphone badges and ABC vehicles. In 1965, ABC graphics designer Bill Kennard submitted a design representing a Lissajous display, as generated when a sine wave signal is applied to the "X" input of an oscilloscope and another at three times the frequency at the "Y" input. The letters "ABC" were added to the design and it was adopted as the ABC's official logo. Kennard was presented with £25 (about AU$715 in 2021) for his design. On 19 October 1974, the Lissajous curve design experienced its first facelift with the line thickened to allow for colour to be used. It would also be treated to the 'over and under' effect, showing the crossover of the line in the design. To celebrate its 70th anniversary on 1 July 2002, the ABC adopted a new logo, which was created by (Annette) Harcus Design in 2001. This logo used a silver 3D texture but the crossover design was left intact and was then used across the ABC's media outlets. After the on-air revival of the 1974 logo since 2014, the ABC gradually reinstated the classic symbol. The most recent change happened in February 2018, with a new logotype and brand positioning under its tagline, Yours. The 2002 silver logo is no longer in use by the corporation. Governance and structure The operations of the ABC are governed by a board of directors, consisting of a managing director, five to seven directors, and until 2006, a staff-elected director. The managing director is appointed by the board for a period of up to five years, but is eligible for renewal. The authority and guidelines for the appointment of directors is provided for in the Australian Broadcasting Corporation Act 1983. Appointments to the ABC Board made by successive governments have often resulted in criticism of the appointees' political affiliation, background, and relative merit. Past appointments have associated directly with political parties – five of fourteen appointed chairmen have been accused of political affiliation or friendship, include Richard Downing and Ken Myer (both of whom publicly endorsed the Australian Labor Party at the 1972 election), as well as Sir Henry Bland. David Hill was close to Neville Wran, while Donald McDonald was considered to be a close friend of John Howard. From 2003 the Howard government made several controversial appointments to the ABC Board, including prominent ABC critic Janet Albrechtsen, Ron Brunton, and Keith Windschuttle. During their 2007 federal election campaign, Labor announced plans to introduce a new system, similar to that of the BBC, for appointing members to the board. Under the new system, candidates for the ABC Board would be considered by an independent panel established "at arm's length" from the Communications Minister. If the minister chose someone not on the panel's shortlist, they would be required to justify this to parliament. The ABC chairman would be nominated by the prime minister and endorsed by the leader of the opposition. A new merit-based appointment system was announced on 16 October 2008, in advance of the new triennial funding period starting in 2009. board members are: As of July 2020 there were 3,730 employees, down from 4,649 in 2019. Funding The ABC is primarily funded by the Australian government, in addition to some revenue received from commercial offerings and its retail outlets. The ABC's funding system is set and reviewed every three years. Until 1948, the ABC was funded directly by radio licence fees; amendments were also made to the Australian Broadcasting Act that meant the ABC would receive its funding directly from the federal government. Licence fees remained until 1973, when they were abolished by the Whitlam Labor government, on the basis that the near-universality of television and radio services meant that public funding was a fairer method of providing revenue for government-owned radio and television broadcasters. In 2014, the ABC absorbed A$254 million in federal budget deficits. Since the 2018 budget handed down by then-Treasurer Scott Morrison, the ABC has been subject to a pause of indexation of operation funding, saving the federal government a total of A$83.7 million over 3 years. In fiscal year 2016–17, the ABC received A$861 million in federal funding, which increased to $865 million per year from 2017 to 2018 to 2018–19, representing a cut in funding of $43 million over three years when accounting for inflation. In 2019–20, the federal budget forecast funding of $3.2 billion over three years ($1.06 billion per year) for the ABC. The Enhanced Newsgathering Fund, a specialised fund for regional and outer-suburban news gathering set up in 2013 by the Gillard government, currently sits at $44 million over three years, a reduction of $28 million per year since the 2016 Australian federal election. This came after speculation that the fund would be removed, to which ABC Acting managing director David Anderson wrote to Communications Minister Mitch Fifield expressing concerns. However, despite the cuts made by Prime Minister Tony Abbott and Communications Minister Malcolm Turnbull and the freeze introduced by Prime Minister Malcolm Turnbull and Communications Minister Mitch Fifield, the ABC itself has published financial data that shows an increase in the taxpayer appropriation to the ABC of 10% in real terms (i.e. above inflation) between 1998 and 2021. The term "where your 8 cents a day goes", coined in the late 1980s during funding negotiations, is often used in reference to the services provided by the ABC. It was estimated that the cost of the ABC per head of population per day was 7.1 cents a day, based on the corporation's 2007–08 "base funding" of . Services Radio The ABC operates 54 local radio stations, in addition to four national networks and international service Radio Australia. In addition, DiG Radio (rebranded as Double J in 2014) launched on digital platforms in 2002, and later spinning off ABC Country and ABC Jazz. ABC Local Radio is the corporation's flagship radio station in each broadcast area. There are 54 individual stations, each with a similar format consisting of locally presented light entertainment, news, talk back, music, sport and interviews, in addition to some national programming such as AM, PM, The World Today, sporting events and Nightlife. the ABC operates 15 radio networks, variously available on AM and FM as well as on digital platforms and the internet. Radio National – A generalist station, also known as RN, broadcasting more than 60 special interest programmes per week covering a range of topics including music, comedy, book readings, radio dramas, poetry, science, health, the arts, religion, social history and current affairs. ABC NewsRadio – A news based service, also known as ABC News on Radio, broadcasting federal parliamentary sittings and news on a 24/7 format with updates on the quarter-hour. Broadcast's news content produced by the ABC itself, as well as programmes relayed from ABC Radio Australia, the BBC World Service, NPR, Deutsche Welle, Radio Netherlands and CNN Radio. ABC Classic – A classical music based station, formerly known as ABC Classic FM. It also plays some jazz and world music. ABC Classic was the ABC's first FM radio service. It was originally known simply as "ABC FM", and for a short time "ABC Fine Music". Triple J – A youth-oriented radio network, with a strong focus on alternative and independent music (especially Australian artists); it is targeted at people aged 18–35. The ABC also operates several stations only available online and on digital platforms: ABC Classic 2 – a sister station to ABC Classic, focussing on performances by Australian artists. Only available on streaming platforms. Double J – a Triple J sister station, focussed on an older audience to Triple J. Triple J Unearthed – a Triple J sister station, playing unsigned and independent Australian talent. Triple j Hottest - a Triple J sister station, playing tracks from the past 30 years of Triple J Hottest 100 countdowns. ABC Jazz – A station exclusively dedicated to Jazz from Australia and the world. ABC Country – An exclusively country music station, mainly focussing on Australian country music. ABC Grandstand – Since November 2020 merged to ABC Sport. ABC Extra – A temporary special events station. ABC Kids – Children's based programming, and a sister station to the ABC Kids television channel. There is also ABC Radio Australia, the international radio station of the ABC (see below). ABC Listen app The ABC Radio app was launched in 2012. This was replaced by the ABC Listen app in September 2017, which included 45 ABC radio stations and audio networks. Television The ABC operates five national television channels: ABC TV (formerly ABC1 from 2008 to 2014), the corporation's original television service, receives the bulk of funding for television and shows first-run comedy, drama, documentaries, and news and current affairs. In each state and territory a local news bulletin is shown at 7pm nightly. ABC TV Plus (formerly ABC2 and ABC Comedy), launched in 2005, shows comedic content in addition to some repeats from ABC TV of which the amount has decreased gradually since ABC TV Plus's inception. It is not a 24-hour channel, but is broadcast daily from 7:30pm to around 3am the following night. The channel shares airspace with the ABC Kids programming block from 5am to 7:30pm. ABC Me (originally ABC3) became a fully fledged channel on 4 December 2009, but has been part of the electronic guide line-up since 2008, broadcasting an ABC1 simulcast until 4 December 2009, then an ABC Radio simulcast and teaser graphic until its official launch. It is broadcast from 6am to around 10pm on weekdays and 6am to 2am the next day on weekends, and consists of a broad range programmes aimed at a young audience aged 6–15, with a core demographic of 8–12. ABC Kids (formerly ABC For Kids on 2 and ABC 4 Kids) is a preschool children's block featuring children's programming aimed at the 0 to 5 age groups. ABC Kids broadcasts during ABC TV Plus downtime, from 5am to 7:30pm daily. ABC News (originally ABC News 24), a 24-hour news channel, featuring the programming from ABC News and Current Affairs, selected programs from the BBC World News channel, coverage of the Federal Parliament's Question Time, documentaries and factual, arts programming and state or national election coverage. Although the ABC's headquarters in Sydney serve as a base for program distribution nationally, ABC Television network is composed of eight state- and territory-based stations, each based in their respective state capital and augmented by repeaters: ABN (Sydney) ABV (Melbourne) ABQ (Brisbane) ABS (Adelaide) ABW (Perth) ABT (Hobart) ABC (Canberra) ABD (Darwin) The eight ABC stations carry opt outs for local programming. In addition to the nightly 7pm news, the stations also broadcast weekly state editions of 7.30 on Friday evenings (until 5 December 2014), state election coverage and in most areas, live sport on Saturday afternoons. There is also ABC Australia, the international TV service of the ABC (see below). Online and digital ABC Online is the name given to the online services of the ABC, which have evolved to cover a large network of websites including those for ABC News, its various television channels, ABC radio; podcasts; SMS, mobile apps and other mobile phone services; vodcasts and video-on-demand through ABC iView. The official launch of ABC Online, then part of the ABC's Multimedia Unit, was on 14 August 1995, charged with developing policy for the ABC's work in web publishing. At first it relied upon funding allocation to the corporation's TV and radio operations, but later began to receive its own. The ABC provided live, online election coverage for the first time in 1996, and limited news content began to be provided in 1997. This unit continued until 2000, when the New Media division was formed, bringing together the ABC's online output as a division similar to television or radio. In 2001 the New Media division became New Media and Digital Services, reflecting the broader remit to develop content for digital platforms such as digital television, becoming an "output division" similar to Television or Radio. In addition to ABC Online, the division also had responsibility over the ABC's two digital television services, Fly TV and the ABC Kids channel, until their closure in 2003. ABC TV Plus, a digital-only free-to-air television channel, launched on 7 March 2005, as ABC2. Unlike its predecessors the new service was not dependent on government funding, instead running on a budget of per year. Minister for Communications Helen Coonan inaugurated the channel at Parliament House three days later. Genre restrictions limiting the types of programming the channel could carry were lifted in October 2006 – ABC TV Plus (then ABC2) was henceforth able to carry programming classified as comedy, drama, national news, sport, and entertainment. In conjunction with the ABC's radio division, New Media and Digital Services implemented the ABC's first podcasts in December 2004. By mid-2006 the ABC had become an international leader in podcasting with over fifty podcast programmes delivering hundreds of thousands of downloads per week, including trial video podcasts of The Chaser's War on Everything and jtv. In February 2007, the New Media & Digital Services division was dissolved and divided up among other areas of the ABC. It was replaced by a new Innovation division, to manage ABC Online and investigate new technologies for the ABC. In 2008, Crikey reported that certain ABC Online mobile sites in development were planned to carry commercial advertising. Screenshots, developed in-house, of an ABC Grandstand sport page include advertising for two private companies. Media Watch later revealed that the websites were to be operated by ABC Commercial and distinguished from the main, advertising-free, mobile website by a distinct logo. In 2015 the Innovation Division was replaced with the Digital Network Division. Angela Clark was head from 2012 until at least the end of financial year 2015/6, but by 2017 she was gone, and the Digital Network fell into the Technology division under the Chief Technology Officer. In May 2017, Helen Clifton was appointed to the new role of Chief Digital and Information Officer, which continues . In December 2019, a refreshed ABC homepage was launched. ABC News is one of Australia's largest and most-visited web sites; from its position as 11th most popular in the country in 2008, in recent years up to 2021 it has maintained top position in the rankings. In June 2023, the broadcaster released its five-year plan, outlining that it would move its resources away from radio and television, and instead dedicate these resources to improving and promoting its digital platforms. International ABC International is responsible for its international operations, which include the internationally broadcast Radio Australia, the Asia-Pacific TV channel ABC Australia, and its ABC International Development (ABCID) branch. In June 2012 Lynley Marshall, former head of ABC Commercial, was appointed CEO of ABC International, filling a role left empty by the retirement of Murray Green. At the time, it was intended that Radio Australia, ABC Australia and ABC News would work together more closely ABC International was at this time a division of the ABC, but it has not been represented as a separate division in the organisational structure of the ABC since 2016, after Marshall's departure in February 2017. There were fears of job losses in the division after the huge budget cuts in 2014, as well as an earlier termination of a contract with the Department of Foreign Affairs, one year into the 10-year contract. On 24 May 2021, Claire Gorman was appointed to an expanded role to manage both the International Strategy and the International Development teams. ABC Australia is an international satellite television service operated by the Australian Broadcasting Corporation, funded by advertising and grants from the Department of Foreign Affairs and Trade. Aimed at the Asia-Pacific region, the service broadcasts a mixture of English language programming, including general entertainment, sport, and current affairs. Radio Australia is an international satellite and internet radio service with transmissions aimed at South-East Asia and the Pacific Islands, although its signals are also audible in many other parts of the world. It features programmes in various languages spoken in these regions, including Mandarin, Indonesian, Vietnamese, Khmer and Tok Pisin. Before 31 January 2017 Radio Australia broadcast short-wave radio signals. Radio Australia bulletins are also carried on WRN Broadcast, available via satellite in Europe and North America. ABC International Development, or ABCID, is a media development unit that promotes public interest journalism and connects with local media in the region. ABCID employs local people in Papua New Guinea and many Pacific countries. The team "provides expertise, training, technical and program support to partner organisations", by working with a variety of organisations, including international development donors, for example through the through the Pacific Media Assistance Scheme (PACMAS). Independence and impartiality Under the Australian Broadcasting Corporation Act 1983, the ABC Board is bound to "maintain the independence and integrity of the Corporation" and to ensure that "the gathering and presentation by the Corporation of news and information is accurate and impartial according to the recognized standards of objective journalism". In relation to impartiality and diversity of perspectives, the current ABC editorial policy requires of the broadcaster that: ABC Commercial The commercial arm of the ABC was established in 1974 under the name Enterprises as a self-funding unit, marketing products relating to the ABC's activities. It was renamed in 2007 to ABC Commercial, The aim of ABC Commercial was "to create, market and retail high quality consumer products which reflect and extend the scope of the ABC's activities". At this time it comprised the ABC Shop, ABC Consumer Publishing and Content Sales, ABC Resource Hire, and ABC Content Services (Archives). ABC Commercial was registered as a business name under Australian Broadcasting Corporation in April 2007 and continues to exist . It includes ABC Music, a leading independent record label; ABC Events, which stages concerts and other events; and publishing and licensing activities by ABC Books, ABC Audio, ABC Magazines and ABC Licensing. ABC Shop Online was wound up at the end of 2018, along with the in-store ABC Centres. In early 2019, ABC Commercial split from the Finance division and became an independent business unit of the ABC. In the financial year 2018–2019, ABC Commercial turned a profit of , which was invested in content production. The ABC Studios and Media Production hires out some of the ABC studios and sound stages, operating as part of ABC Commercial. The studios for hire are in Sydney (Studios 21, 22, 16), Melbourne (31), Adelaide (51B) and Perth (61). Orchestras Up until the installation of disc recording equipment in 1935, all content broadcast on the ABC was produced live, including music. For this purpose, the ABC established broadcasting orchestras in each state, and in some centres also employed choruses and dance bands. This became known as the ABC Concert Music Division, which was controlled by the Federal Director of Music – the first of whom was W. G. James. In 1997, the ABC divested all ABC orchestras from the Concerts department of the ABC into separate subsidiary companies, allied to a service company known as Symphony Australia, and on 1 January 2007 the orchestras were divested into independent companies. The six state orchestras are: Adelaide Symphony Orchestra Melbourne Symphony Orchestra Queensland Symphony Orchestra Sydney Symphony Orchestra Tasmanian Symphony Orchestra West Australian Symphony Orchestra ABC Friends ABC Friends, formerly Friends of the ABC (FABC), consists of independent organisations in each state and territory, under an umbrella organisation established in December 2016, ABC Friends National Inc. In 1976, three independent groups were formed: Aunty's Nieces and Nephews in Melbourne, Friends of the ABC (NSW) Inc. (now ABC Friends NSW & ACT) and Friends of the ABC (SA) (since 2007/2008, ABC Friends SA/NT). The groups were formed by citizens who were concerned about government threats to make deep cuts to the ABC's budget. Historian Ken Inglis wrote that "The Friends were in the line of those people who had affirmed over the years that the ABC was essential to the nation". Over the years, independent state organisations were established, run by committees, and in January 2014 the name of each was changed to ABC Friends. The objectives of ABC Friends National are stated as follows: Controversies Defamation The ABC infamously lost a defamation case against Heston Russell, where they withdrew a truth defence and opted for the case to be heard under a public interest defence. In the landmark ruling, Justice Lee awarded Heston $390,000 + interest and damages which are ultimately funded by taxpayer dollars. Estimates of legal expenses range from AUD$1.2m – $3m and could have been avoided if an earlier settlement offer of $99,000 and removal of the published articles had been taken by the broadcaster. The ABC Managing Director, David Anderson, who took home a six-figure pay rise shortly after the defamation case loss, outlined in senate estimates that he would not apologise to Russell for the false reporting. Recordings of Willacy's interviews that formed part of the defamation case were garnished as part of the legal discovery process. They demonstrated the inappropriate and targeted style of journalism employed for the story and were made available to Ben Fordham's 2GB radio program. Perceived bias External critics have complained in particular of left-wing political bias at the broadcaster, citing a prominence of Labor Party-connected journalists hosting masthead political programs or a tendency to favour "progressive" over "conservative" political views on issues such as immigration, asylum seekers, the republic, multiculturalism, Indigenous reconciliation, feminism, environmentalism, and same-sex marriage. In December 2013, former judge and ABC chair James Spigelman announced that four independent audits would be conducted each year in response to the allegations of bias in the reporting of news and current affairs. ABC Friends have observed that "Most of the complaints about bias in the ABC have come from the government of the day – Labor or Liberal. Significantly both parties have been far less hostile to the ABC when in opposition". Reviews and investigations Reviews of the ABC are regularly commissioned and sometimes not released. Both internal and external research has been conducted on the question of bias at the ABC. These include the following: A 2004 Roy Morgan media credibility survey found that journalists regarded ABC Radio as the most accurate news source in the country and the ABC as the second "most politically biased media organisation in Australia". A 2013 University of the Sunshine Coast study of the voting intentions of journalists found that 73.6% of ABC journalists supported Labor or The Greens – with 41% supporting the Greens (whereas only around 10% of people in the general population voted Green). At the 2016 federal election, a study commissioned by the ABC and conducted by Isentia compiled share-of-voice data and found that the ABC devoted 42.6% of election coverage to the Coalition government (this compares to the 42.04% vote received by the Coalition in the House of Representatives (HOR)), 35.9% to the Labor opposition (34.73% HOR), 8% to The Greens(10.23% HOR), 3.1% to independents (1.85% HOR), 2.2% to the Nick Xenophon Team (1.85% HOR) and 8.1% to the rest. However, the ABC itself notes the "significant limitations around the value of share of voice data" as "duration says nothing about tone or context". In December 2020, the Board commissioned its 19th editorial review by an independent reviewer, which found that the ABC's news coverage of lead-up to the 2019 Australian election was "overwhelmingly positive and unbiased", although it also found that specific episodes of The Drum and Insiders reflected too narrow a range of viewpoints. The government forced the publication of the report after Coalition senator James McGrath raised a motion in the Senate, which led to ABC Chair Ita Buttrose and managing director David Anderson writing to the president of the Senate, Scott Ryan, to express their concerns about the use of the such powers, which went against the public interest. Relationships with government Labor Prime Minister Bob Hawke considered the ABC's coverage of the 1991 Gulf War to be biased. In 1996, conservative Opposition Leader John Howard refused to have Kerry O'Brien of the ABC moderate the television debates with Labor Prime Minister Paul Keating because Howard saw O'Brien as biased against the Coalition. Liberal Prime Minister Tony Abbott perceived the ABC to be left wing and hostile to his government, while Malcolm Turnbull enjoyed better relations with the national broadcaster. Turnbull's successor, Scott Morrison, once again presided over "strained" relations between the Government and the ABC. Under Morrison's leadership, an investigation was launched into the ABC and its complaints-handling process—a decision which was criticised by Ita Buttrose as "political interference". The inquiry was abandoned the following June. Specific topics The Catholic Church and George Pell The ABC's coverage of the issue of sexual abuse in the Catholic Church received praise and criticism. The Melbourne Press Club presented the 2016 Quill for Coverage of an Issue or Event for the report George Pell and Sexual Abuse in the Catholic Church, and the 2016 Golden Quill award to Louise Milligan and Andy Burns for their extensive coverage of Cardinal George Pell's evidence given at the Royal Commission into Institutional Responses to Child Sexual Abuse. The ABC Media Watch program of 20 April 2020 noted that the ABC had been accused of leading a "witch hunt" against Cardinal Pell. Media Watch reported that, following his acquittal, Pell said the ABC gave an "overwhelming presentation of one view and only one view". Media Watch also canvassed other criticisms including from The Australian newspaper's editor-at-large Paul Kelly, who charged the ABC with having run a "sustained campaign against Pell". Media Watch also offered criticism of its own, noting Louise Milligan and the Four Corners program had failed to canvass any of Pell's defence from the trial and "lined up witnesses condemning Pell", while social media commentary by Barrie Cassidy and Quentin Dempster had undermined the presumption of innocence. Margaret Simons similarly noted in The Guardian that "there has been some social media activity by ABC journalists that looks very much like lobbying against Pell..." Environmentalism Planet Slayer was an ABC website run by scientist Bernie Hobbs to teach children about the environment in around 2008/9. It included a "Greenhouse Calculator" which aimed to help children to work out their carbon footprint by providing an estimate of the age a person needs to die if they are not to use more than their fair share of the Earth's resources. Victorian Liberal senator Mitch Fifield criticised a cartoon series on the site for portraying those who eat meat, loggers, and workers in the nuclear industry as "evil". ABC managing director Mark Scott said the site was not designed to offend anyone, but instead have children think about environmental issues.

Alexandria Troas

Alexandria Troas ("Alexandria of the Troad"; ; ) is the site of an ancient Greek city situated on the Aegean Sea near the northern tip of Turkey's western coast, the area known historically as Troad, a little south of Tenedos (modern Bozcaada). It is located southeast of modern Dalyan, a village in the Ezine district of Çanakkale Province. The site sprawls over an estimated ; among the few structures remaining today are a ruined bath, an odeon, a theatre, gymnasium complex and a recently uncovered stadion. The circuit of the old walls can still be traced. History Hellenistic According to Strabo, this site was first called Sigeia (Σιγία); around 306 BC Antigonus refounded the city as the much-expanded Antigonia Troas by settling the people of five other towns in Sigeia, including the once influential city of Neandreia. It did not receive its name until its name was changed by Lysimachus to Alexandria Troas, in 301 BC, in memory of Alexander III of Macedon (Pliny merely states, in his view, that the name changed from Antigonia to Alexandria). However, Pliny's view is not correct, because the city continued being called Alexandria Troas, and so is also stated in the 4th-5th c. AD Tabula Peutingeriana. As the chief port of north-west Asia Minor, the place prospered greatly in Roman times, becoming a "free and autonomous city" as early as 188 BC, and the existing remains sufficiently attest its former importance. In its heyday the city may have had a population of about 100,000. Strabo mentions that a Roman colony was created at the location in the reign of Augustus, named Colonia Alexandria Augusta Troas (called simply Troas during this period). Augustus, Hadrian and the rich grammarian Herodes Atticus contributed greatly to its embellishment; the aqueduct still preserved is due to the latter. Julius Caesar and Constantine considered making Troas the capital of the Roman Empire. Roman In Roman times, it was a significant port for travelling between Anatolia and Europe. According to the account in the Acts of the Apostles, Paul of Tarsus sailed for Europe for the first time from Alexandria Troas and returned there from Europe (it was there that the episode of the raising of Eutychus is said to have occurred). Ignatius of Antioch also paused at this city before continuing to his martyrdom at Rome. Byzantine Several of its later bishops are known: Marinus in 325; Niconius in 344; Sylvanus at the beginning of the 5th century; Pionius in 451; Leo in 787; Peter, friend of the Patriarch Ignatius, and adversary to Michael, in the ninth century. In the 10th century Troas is given as a suffragan of Cyzicus and distinct from the famous Troy (Heinrich Gelzer, Ungedruckte ... Texte der Notitiae episcopatuum, 552; Georgii Cyprii descriptio orbis romani, 64); it is not known when the city was destroyed and the diocese disappeared. The bishopric remains a titular see of the Catholic Church under the name Troas, vacant since 1971.<ref>Annuario Pontificio 2013 (Libreria Editrice Vaticana 2013 ), p. 997</ref> Troas is also a titular see of the Eastern Orthodox Church under the Ecumenical Patriarchate. Bishop Savas (Zembillas) of Troas served as hierarch from 2002 to 2011, and then became Metropolitan Savas (Zembillas) of Pittsburgh in the Greek Orthodox Archdiocese of America. Ottoman Karasid Turkomans settled in the area of the Troad in the 14th century. Their beylik was conquered by the Ottomans in 1336. The ruins of Alexandria Troas came to be known among the Turks as Eski Stambul, the "Old City". The site's stones were much plundered for building material (for example Mehmed IV took columns to adorn his Yeni Valide Mosque in Istanbul). As of the mid-18th century the site served as "a lurking place for bandetti". Modern By 1911, the site had been overgrown with Vallonea oaks and much plundered, but the circuit of the old walls could still be traced, and in several places they were fairly well preserved. They had a circumference of about ten kilometres, and were fortified with towers at regular intervals. Remains of an ancient bath and gymnasium complex can be found within this area; this building is locally known as Bal Saray (Honey Palace) and was originally endowed by Herodes Atticus in the year 135. Trajan built an aqueduct which can still be traced. The harbour had two large basins, now almost choked with sand. It is the subject of an early twenty-first century study by German archaeologists digging and surveying at the site. Their excavation uncovered the remains of a large stadium dating to about 100 BC.

https://en.wikipedia.org/wiki/Akira%20Toriyama

Akira Toriyama

is a Japanese manga artist and character designer. He first achieved mainstream recognition for his highly successful manga series Dr. Slump, before going on to create Dragon Ball (his best-known work) and acting as a character designer for several popular video games such as the Dragon Quest series, Chrono Trigger, and Blue Dragon. Toriyama is regarded as one of the authors who changed the history of manga, as his works are highly influential and popular, particularly Dragon Ball, which many manga artists cite as a source of inspiration. He earned the 1981 Shogakukan Manga Award for best shōnen manga with Dr. Slump, and it went on to sell over 35 million copies in Japan. It was adapted into a successful anime series, with a second anime created in 1997, 13 years after the manga ended. His next series, Dragon Ball, would become one of the most popular and successful manga in the world. Having sold 260 million copies worldwide, it is one of the best-selling manga series of all time and is considered to be one of the main reasons for the period when manga circulation was at its highest in the mid-1980s and mid-1990s. Overseas, Dragon Balls anime adaptations have been more successful than the manga and are credited with boosting anime's popularity in the Western world. In 2019, Toriyama was decorated a Chevalier of the French Ordre des Arts et des Lettres for his contributions to the arts. Early life Akira Toriyama was born in Nagoya, Aichi, Japan. He drew pictures from a young age, mainly of the animals and vehicles that he was also fond of. He related being blown away after seeing One Hundred and One Dalmatians (1961), and said he was drawn deeper into the world of illustration by hoping to draw pictures that good. He was shocked again in elementary school when he saw the manga collection of a classmate's older brother, and again when he saw a television set for the first time at a neighbor's house. He cited Osamu Tezuka's Astro Boy (1952–1968) as the original source for his interest in manga. Toriyama has recalled that when he was in elementary school all of his classmates drew imitating anime and manga, as a result of not having many forms of entertainment. He believes that he began to advance above everyone else when he started drawing pictures of his friends. Despite being engrossed with manga in elementary school, Toriyama said he took a break from it in middle school, probably because he became more interested in films and TV shows. When asked if he had any formative experiences with tokusatsu entertainment, Toriyama said he enjoyed the Ultraman TV show and Gamera series of kaiju films. Toriyama said it was a "no-brainer" that he would attend a high school focused on creative design, but admitted he was more interested in having fun with friends. Although he still did not read much manga, he would draw one himself every once in a while. Despite his parents' strong opposition to it, Toriyama was confident about going into the work force upon graduation instead of continuing his education. He worked at an advertising agency in Nagoya designing posters for three years. Although Toriyama said he adapted to the job quickly, he admitted that he was often late because he is not a "morning person" and often got reprimanded for dressing casually, until he got sick of the environment and quit. Career Early work and Dr. Slump (1978–1983) Needing money after quitting his job at the age of 23, Toriyama entered the manga industry by submitting a work to an amateur contest in Kodansha's Weekly Shōnen Magazine, which he had randomly picked up in a coffee shop. The timing did not line up for that contest, but another shōnen magazine, Weekly Shōnen Jump, accepted submissions for their Newcomer Award every month. Kazuhiko Torishima, who would become his editor, read and enjoyed Toriyama's manga, but it was not eligible to compete because it was a parody of Star Wars instead of an original work. Torishima sent the artist a telegram and encouraged him to keep drawing and sending him manga. This resulted in Wonder Island, which became Toriyama's first published work when it was published in Weekly Shōnen Jump in 1978. However, it came in last place in the readers survey. Toriyama later said that he had planned to quit manga after getting paid, but because Wonder Island 2 (1978) was also a "flop," his stubbornness would not let him and he continued to draw failed stories for a year; claiming around 500 pages' worth, including the published Today's Highlight Island (1979). He said he learned a lot during this year and even had some fun. When Torishima told him to draw a female lead character, Toriyama hesitantly created 1979's Tomato the Cutesy Gumshoe, which had some success. Feeling encouraged, he decided to draw another female lead and created Dr. Slump. Dr. Slump, which was serialized in Weekly Shōnen Jump from 1980 to 1984, was a huge success and made Toriyama a household name. It follows the adventures of a perverted professor and his small but super-strong robot Arale. In 1981, Dr. Slump earned Toriyama the Shogakukan Manga Award for best shōnen or shōjo manga series of the year. An anime adaptation began airing that same year, during the prime time Wednesday 19:00 slot on Fuji TV. Adaptations of Toriyama's work would occupy this time slot continuously for 18 years—through Dr. Slumps original run, Dragon Ball and its two sequels, and finally a rebooted Dr. Slump concluding in 1999. By 2008, the Dr. Slump manga had sold over 35 million copies in Japan. Although Dr. Slump was popular, Toriyama wanted to end the series within roughly six months of creating it, but Shueisha would only allow him to do so if he agreed to start another serial for them shortly after. So he worked with Torishima on several one-shots for Weekly Shōnen Jump and the monthly Fresh Jump. In 1981, Toriyama was one of ten artists selected to create a 45-page work for Weekly Shōnen Jumps Reader's Choice contest. His manga Pola & Roid took first place. Toriyama was selected to participate in the contest again in 1982 and submitted Mad Matic. His one-shot Pink was published in the December issue of Fresh Jump. Selected to participate in Weekly Shōnen Jumps Reader's Choice contest for a third time, Toriyama had the bad luck of drawing the first slot and had to work over New Year's on 1983's Chobit. Angry that it was unpopular, he decided to try again and created Chobit 2 (1983). An official Toriyama fan club, , was established in 1982. Its newsletters were called Bird Land Press and were sent to members until the club closed in 1987. Toriyama founded Bird Studio in the early 1980s, which is a play on his name; meaning "bird". He began employing an assistant, mostly to work on backgrounds. Dragon Ball and international success (1983–1997) Torishima suggested that, as Toriyama enjoyed kung fu films, he should create a kung fu shōnen manga. This led to the two-part Dragon Boy, published in the August and October 1983 issues of Fresh Jump. It follows a boy, adept at martial arts, who escorts a princess on a journey back to her home country. Dragon Boy was well-received and evolved to become the serial Dragon Ball in 1984. But before that, The Adventure of Tongpoo was published in Weekly Shōnen Jumps 52nd issue of 1983 and also contained elements that would be included in Dragon Ball. Serialized in Weekly Shōnen Jump from 1984 to 1995 and having sold 159.5million tankōbon copies in Japan alone, Dragon Ball is one of the best-selling manga of all time. It began as an adventure/gag manga but later turned into a martial arts fighting series, considered by many to be the "most influential shōnen manga." Dragon Ball was one of the main reasons for the magazine's circulation hitting a record high of 6.53 million copies (1995). At the series' end, Toriyama said that he asked everyone involved to let him end the manga, so he could "take some new steps in life." During that near-11-year period, he produced 519 chapters that were collected into 42 volumes. Moreover, the success of the manga led to five anime adaptations, several animated films, numerous video games, and mega-merchandise. Aside from its popularity in Japan, Dragon Ball was successful internationally as well, including Asia, Europe, and the Americas, with 300–350million copies of the manga sold worldwide. While Toriyama was serializing Dragon Ball weekly, he continued to create the occasional one-shot manga. In 1986, Mr. Ho was published in the 49th issue of Weekly Shōnen Jump. The following year saw publication of Young Master Ken'nosuke, which had a Japanese jidaigeki setting. Toriyama published two Weekly Shōnen Jump one-shots in 1988; The Elder and Little Mamejiro. Karamaru and the Perfect Day followed in issue #13 of 1989. Also during Dragon Balls serialization, Torishima recruited him to work as character designer for the 1986 role-playing video game Dragon Quest. The artist admitted he was pulled into it without even knowing what an RPG was and that it made his already busy schedule even more hectic, but he was happy to have been a part after enjoying the finished game. Toriyama has continued to work on every installment in the Dragon Quest series. He has also served as the character designer for the Super Famicom RPG Chrono Trigger (1995) and for the fighting games Tobal No. 1 (1996) and Tobal 2 (1997) for the PlayStation. The September 23, 1988 festival film Kosuke & Rikimaru: The Dragon of Konpei Island marks the first time Toriyama made substantial contributions to an animation. He came up with the original story idea, co-wrote the screenplay with its director Toyoo Ashida, and designed the characters. Short stories and other projects (1996–2011) A third anime adaptation based on Dragon Ball, entitled Dragon Ball GT, began airing in 1996, though this was not based on Toriyama's manga directly. Toriyama was still however involved in some overarching elements, including the name of the series and designs for the main cast. Toriyama continued drawing manga in this period, predominantly one-shots and short (100–200-page) pieces, including Cowa! (1997–1998), Kajika (1998), and Sand Land (2000). On December 6, 2002, Toriyama made his only promotional appearance in the United States at the launch of Weekly Shōnen Jumps North American counterpart, Shonen Jump, in New York City. Toriyama's Dragon Ball and Sand Land were published in the magazine in the first issue, which also included an in-depth interview with him. On March 27, 2005, CQ Motors began selling an electric car designed by Toriyama. The one-person QVOLT is part of the company's Choro-Q series of small electric cars, with only 9 being produced. It costed 1,990,000 yen (about $19,000 US), has a top speed of and was available in 5 colors. Toriyama stated that the car took over a year to design, "but due to my genius mini-model construction skills, I finally arrived at the end of what was a very emotional journey." He worked on a 2006 one-shot called Cross Epoch, in cooperation with One Piece creator Eiichiro Oda. The story is a short crossover that presents characters from both Dragon Ball and One Piece. Toriyama was the character designer and artist for the 2006 Mistwalker Xbox 360 exclusive RPG Blue Dragon, working with Hironobu Sakaguchi and Nobuo Uematsu, both of whom he had previously worked with on Chrono Trigger. At the time, Toriyama felt the 2007 Blue Dragon anime might potentially be his final work in animation. In 2008, he collaborated with Masakazu Katsura, his good friend and creator of I"s and Zetman, for the Jump SQ one-shot Sachie-chan Good!!. It was later published in North America in the free SJ Alpha Yearbook 2013, which was mailed out to annual subscribers of the digital manga magazine Shonen Jump Alpha in December 2012. The two worked together again in 2009, for the three-chapter one-shot Jiya in Weekly Young Jump. Toriyama was engaged by 20th Century Fox as a creative consultant on Dragonball Evolution, an American live-action film adaptation of Dragon Ball. He is also credited as an executive producer on the 2009 film, which failed both critically and financially. Toriyama later stated in 2013 that he had felt the script did not "capture the world or the characteristics" of his series and was "bland" and not interesting, so he cautioned them and gave suggestions for changes. But the Hollywood producers did not heed his advice, "And just as I thought, the result was a movie I cannot call Dragon Ball." Avex Trax commissioned Toriyama to draw a portrait of pop singer Ayumi Hamasaki, and it was printed on the CD of her 2009 single "Rule", which was used as the theme song to the film. Toriyama drew a 2009 manga titled Delicious Island's Mr. U for Anjō's Rural Society Project, a nonprofit environmental organization that teaches the importance of agriculture and nature to young children. They originally asked him to do the illustrations for a pamphlet, but Toriyama liked the project and decided to expand it into a story. It is included in a booklet about environmental awareness that is distributed by the Anjō city government. As part of Weekly Shōnen Jumps "Top of the Super Legend" project, a series of six one-shots by famed Jump artists, Toriyama created Kintoki for its November 15, 2010 issue. He collaborated with Weekly Shōnen Jump to create a video to raise awareness and support for those affected by the 2011 Tōhoku earthquake and tsunami on March 11, 2011. Return to Dragon Ball (2012–present) In 2012, Dragon Ball Z: Battle of Gods was announced to be in development, with Toriyama involved in its creation. The film marked the series' first theatrical film in 17 years, and the first time Toriyama had been involved in one as early as the screenwriting stages. The film opened on March 30, 2013. A special "dual ticket" that could be used to see both Battle of Gods and One Piece Film: Z was created with new art by both Toriyama and Eiichiro Oda. On March 27, the "Akira Toriyama: The World of Dragon Ball" exhibit opened at the Takashimaya department store in Nihonbashi, garnering 72,000 visitors in its first nineteen days. The exhibit was separated into seven areas. The first provided a look at the series' history, the second showed the 400-plus characters from the series, the third displayed Toriyama's manga manuscripts from memorable scenes, the fourth showed special color illustrations, the fifth displayed rare Dragon Ball-related materials, the sixth included design sketches and animation cels from the anime, and the seventh screened Dragon Ball-related videos. It was there until April 15, when it moved to Osaka from April 17 to 23, and ended in Toriyama's native Nagoya from July 27 to September 1. To celebrate the 45th anniversary of Weekly Shōnen Jump, Toriyama launched a new manga series in its July 13, 2013 issue titled Jaco the Galactic Patrolman. Viz Media began serializing it in English in their digital Weekly Shonen Jump magazine, beginning just two days later. The final chapter reveals that the story is set before the events of Dragon Ball and features some of its characters. The follow-up film to Battle of Gods, Resurrection 'F', released on April 18, 2015, features even more contributions from Toriyama, who personally wrote its original script. Toriyama provides the basic story outline and some character designs for Dragon Ball Super, which began serialization in V Jump in June 2015 with an anime counterpart following in July. Although the anime ended in 2018, he continues to provide story ideas for the manga while Toyotarou illustrates it. Dragon Ball Super: Broly, released in theaters on December 14, 2018, and Dragon Ball Super: Super Hero, released on June 11, 2022, continued Toriyama's deep involvement with the films. Personal life Toriyama married on May 2, 1982. She is a former manga artist from Nagoya under the pen name , and occasionally helped Toriyama and his assistant on Dr. Slump when they were short on time. They have two children: a son named born on March 23, 1987, and a daughter born in October 1990. Toriyama lives in his home studio in Kiyosu. He is a well-known recluse, who avoids appearing in public or media. Toriyama has a love of cars and motorcycles, something he inherited from his father who used to race motorbikes and operated an auto repair business for a brief time, although he does not understand the mechanics himself. The author is an animal lover, having kept many different species of birds, dogs, cats, fish, lizards, and bugs as pets since childhood. Some were used as models for characters he created such as Karin and Beerus. Toriyama has had a lifelong passion for plastic models, and has designed several for the Fine Molds brand. He also collected autographs of famous manga artists, having over 30 including Yudetamago and Hisashi Eguchi, a hobby he gave to the character Peasuke Soramame. Style Toriyama admires Osamu Tezuka's Astro Boy and was impressed by Walt Disney's One Hundred and One Dalmatians, which he remembers for its high-quality animation. He was a fan of Hong Kong martial arts films, especially Bruce Lee films such as Enter the Dragon (1973) and Jackie Chan films such as Drunken Master (1978), which went on to have a large influence on his later work. The artist has also cited the science fiction films Alien (1979) and Galaxy Quest (1999) as influences. Toriyama stated he was influenced by animator Toyoo Ashida and the anime television series adaptation of his own Dragon Ball; from which he learned that separating colors instead of blending them makes the art cleaner and coloring illustrations easier. It was Toriyama's sound effects in Mysterious Rain Jack that caught the eye of Kazuhiko Torishima, who explained that usually they are written in katakana, but Toriyama used the Roman alphabet which he found refreshing. Torishima has stated that Toriyama aimed to be a gag manga artist because the competitions that he submitted to early on required entries in the gag category to only be 15 pages long, compared to story manga entries which had to be 31. In his opinion, Torishima stated that Toriyama excels in black and white, utilizing black areas, as a result of not having had the money to buy screentone when he started drawing manga. He also described Toriyama as a master of convenience and "sloppy, but in a good way." For instance, in Dragon Ball, destroying scenery in the environment and giving Super Saiyans blond hair were done in order to have less work in drawing and inking. Torishima claimed that Toriyama draws what he finds interesting and is not mindful of what his readers think. Torishima stated that Toriyama does not get much inspiration from other comics as Toriyama chooses not to re-read previous works nor read works done by other manga artists; Torishima supports that practice. Dr. Slump is mainly a comedy series, filled with puns, toilet humor, and sexual innuendos. But it also contained many science fiction elements: aliens, anthropomorphic characters, time travel, and parodies of works such as Godzilla, Star Wars, and Star Trek. Toriyama also included many real-life people in the series, such as his assistants, wife, and colleagues (such as Masakazu Katsura), but most notably his editor Kazuhiko Torishima as the series' main antagonist, Dr. Mashirito. A running gag in Dr. Slump that utilizes feces has been reported as an inspiration for the Pile of Poo emoji. When Dragon Ball began, it was loosely based on the classic Chinese novel Journey to the West, with Goku being Sun Wukong and Bulma as Tang Sanzang. It was also inspired by Hong Kong martial arts films, particularly those of Jackie Chan, and was set in a fictional world based on Asia, taking inspiration from several Asian cultures including Japanese, Chinese, Indian, Central Asian, Arabic, and Indonesian cultures. Toriyama continued to use his characteristic comedic style in the beginning, but over the course of serialization this slowly changed, with him turning the series into a "nearly-pure fighting manga" later on. He did not plan out in advance what would happen in the series, instead choosing to draw as he went. This, coupled with him simply forgetting things he had already drawn, caused him to find himself in situations that he had to write himself out of. Toriyama was commissioned to illustrate the characters and monsters for the first Dragon Quest video game (1986) in order to separate it from other role-playing games of the time. He has since worked on every installment in the series. For each game Yuji Horii first sends rough sketches of the characters with their background information to Toriyama, who then re-draws them. Lastly, Horii approves the finished work. Toriyama explained in 1995 that for video games, because the sprites are so small, as long as they have a distinguishing feature so people can tell which character it is, he can make complex designs without concern of having to reproduce it like he usually would in manga. Besides the character and monster designs, Toriyama also does the games' packaging art and, for Dragon Quest VIII, the boats and ships. In 2016, Toriyama revealed that because of the series' established time period and setting, his artistic options are limited, which makes every iteration harder to design for than the last. The series' Slime character, which has become a mascot for the franchise, is considered to be one of the most recognizable figures in gaming. Manga critic Jason Thompson declared Toriyama's art influential, saying that his "extremely personal and recognizable style" was a reason for Dragon Ball'''s popularity. He points out that the popular shōnen manga of the late 1980s and early 1990s had "manly" heroes, such as City Hunter and Fist of the North Star, whereas Dragon Ball starred the cartoonish and small Goku, thus starting a trend that Thompson says continues to this day. Toriyama himself said he went against the normal convention that the strongest characters should be the largest in terms of physical size, designing many of the series' most powerful characters with small statures. Thompson concluded his analysis by saying that only Akira Toriyama drew like this at the time and that Dragon Ball is "an action manga drawn by a gag manga artist." However, James S. Yadao, author of The Rough Guide to Manga, points out that an art shift does occur in the series, as the characters gradually "lose the rounded, innocent look that [Toriyama] established in Dr. Slump and gain sharper angles that leap off the page with their energy and intensity." Legacy and accolades Thompson stated in 2011 that "Dragon Ball is by far the most influential shonen manga of the last 30 years, and today, almost every Shōnen Jump artist lists it as one of their favorites and lifts from it in various ways." David Brothers of ComicsAlliance wrote that: "Like Osamu Tezuka and Jack Kirby before him, Toriyama created a story with his own two hands that seeped deep into the hearts of his readers, creating a love for both the cast and the medium at the same time." In a rare 2013 interview, commenting on Dragon Balls global success, Toriyama admitted, "Frankly, I don't quite understand why it happened. While the manga was being serialized, the only thing I wanted as I kept drawing was to make Japanese boys happy." He had previously stated in 2010, "The truth is, I didn't like being a manga artist very much. It wasn't until relatively recently that I realized it's a wonderful job." Many artists have named Toriyama and Dragon Ball as influences, including One Piece author Eiichiro Oda, Naruto creator Masashi Kishimoto, Fairy Tail and Rave author Hiro Mashima, Boruto: Naruto Next Generations illustrator Mikio Ikemoto, Venus Versus Virus author Atsushi Suzumi, Bleach creator Tite Kubo, Black Cat author Kentaro Yabuki, and Mr. Fullswing author Shinya Suzuki. German comic book artist Hans Steinbach was strongly influenced by Toriyama, and Thai cartoonist Wisut Ponnimit cited Toriyama as one of his favorite cartoonists. Ian Jones-Quartey, a producer of the American animated series Steven Universe, is a fan of both Dragon Ball and Dr. Slump, and uses Toriyama's vehicle designs as reference for his own. He also stated that "We're all big Toriyama fans on [Steven Universe], which kind of shows a bit." French director Pierre Perifel cited Toriyama and Dragon Ball as influences on his DreamWorks Animation film The Bad Guys. In 2008, Oricon conducted a poll of people's favorite manga artists, with Toriyama coming in second, behind only Nana author Ai Yazawa. However, he was number one among male respondents and among those over 30 years of age. They held a poll on the Mangaka that Changed the History of Manga in 2010, mangaka being the Japanese word for a manga artist. Toriyama came in second, after only Osamu Tezuka, due to his works being highly influential and popular worldwide. Toriyama won the Special 40th Anniversary Festival Award at the 2013 Angoulême International Comics Festival, honoring his years in cartooning. He actually received the most votes for the festival's Grand Prix de la ville d'Angoulême award that year; however, the selection committee chose Willem as the recipient. In a 2014 NTT Docomo poll for the manga artist that best represents Japan, Toriyama came in third place. That same year, entomologist Enio B. Cano named a new species of beetle Ogyges toriyamai after Toriyama, and another Ogyges mutenroshii, after the Dragon Ball character Muten Roshi. Toriyama was decorated a Chevalier or "Knight" of the Ordre des Arts et des Lettres by the French government on May 30, 2019 for his contributions to the arts. He was also a 2019 nominee for entry into the Will Eisner Hall of Fame. Due to his video game design work, IGN named Toriyama number 74 on their list of the Top 100 Game Creators of All Time.

Amiga 500

The Amiga 500, also known as the A500, was the first popular version of the Amiga home computer, "redefining the home computer market and making so-called luxury features such as multitasking and colour a standard long before Microsoft or Apple sold these to the masses". It contains the same Motorola 68000 as the Amiga 1000, as well as the same graphics and sound coprocessors, but is in a smaller case similar to that of the Commodore 128. Commodore announced the Amiga 500 at the January 1987 winter Consumer Electronics Showat the same time as the high-end Amiga 2000. It was initially available in the Netherlands in April 1987, then the rest of Europe in May. In North America and the UK it was released in October 1987 with a list price. It competed directly against models in the Atari ST line. The Amiga 500 was sold in the same retail outlets as the Commodore 64, as opposed to the computer store-only Amiga 1000. It proved to be Commodore's best-selling model, particularly in Europe. Although popular with hobbyists, arguably its most widespread use was as a gaming machine, where its graphics and sound were of significant benefit. It was followed by a revised version of the computer, the Amiga 500 Plus, and the 500 series was discontinued in 1992. Releases In mid-1988, the Amiga 500 dropped its price from £499 to £399 (https://amr.abime.net/issue_535_pages page 7), and it was later bundled with the Batman Pack in the United Kingdom (from October 1989 to September 1990) which included the games Batman, F/A-18 Interceptor, The New Zealand Story and the bitmap graphics editor Deluxe Paint 2. Also included was the Amiga video connector which allows the A500 to be used with a conventional CRT television. In November 1991, the enhanced Amiga 500 Plus replaced the 500 in some markets. It was bundled with the Cartoon Classics pack in the United Kingdom at £399, although many stores still advertised it as an 'A500'. The Amiga 500 Plus was virtually identical except for its new operating system, different 'trap-door' expansion slot and slightly different keyboard, and in mid-1992, the two were discontinued and effectively replaced by the Amiga 600. In late 1992, Commodore released the Amiga 1200, a machine closer in concept to the original Amiga 500, but with significant technical improvements. Despite this, neither the A1200 nor the A600 replicated the commercial success of its predecessor. By this time, the home market was strongly shifting to IBM PC compatibles with VGA graphics and the "low-cost" Macintosh Classic, LC, and IIsi models. Description Outwardly resembling the Commodore 128 and codenamed "Rock Lobster" during development, the Amiga 500's base houses a keyboard and a CPU in one shell, unlike the Amiga 1000. The keyboard for Amiga 500s sold in the United States contains 94 keys, including ten function keys, four cursor keys, and a number pad. All European versions the keyboard have an additional two keys, except for the British variety, which still uses 94 keys. It uses a Motorola 68000 microprocessor running at in NTSC regions and in PAL regions. The CPU implements a 32-bit model and has 32-bit registers, but it has a 16-bit main ALU and uses a 16-bit external data bus and a 23-bit address bus, providing a maximum of 16 MB of address space. Also built in to the base of the computer is a -inch floppy disk drive. The user can also install up to three external floppy drives, either - or -inch, via the disk drive port. The second and third additional drives are installed by daisy-chaining them. Supported by these drives are double-sided disks with a capacity of 901,120 bytes, as well as 360- and 720-KB disks formatted for IBM PC compatibles. The earliest Amiga 500 models use nearly the same Original Amiga chipset as the Amiga 1000. So graphics can be displayed in multiple resolutions and color depths, even on the same screen. Resolutions vary from 320×200 (up to 32 colors) to 640×400 (up to 16 colors) for NTSC (704×484 overscan) and 320×256 to 640×512 for PAL (704×576 overscan.) The system uses planar graphics, with up to five bitplanes (four in high resolution) allowing 2-, 4-, 8-, 16-, and 32-color screens, from a palette of 4096 colors. Two special graphics modes are also available: Extra HalfBrite, which uses a 6th bitplane as a mask to cut the brightness of any pixel in half (resulting in 32 arbitrary colors plus 32 more colors set at half the value of the first 32), and Hold-And-Modify (HAM) which allows all 4096 colors to be used on screen simultaneously. Later revisions of the chipset are PAL/NTSC switchable in software. The sound chip produces four hardware-mixed channels, two to the left and two to the right, of 8-bit PCM at a sampling frequency up to . Each hardware channel has its own independent volume level and sampling rate, and can be designated to another channel where it can modulate both volume and frequency using its own output. With DMA disabled it's possible to output with a sampling frequency up to . There is a common trick to output sound with 14-bit precision that can be combined to output 14-bit sound. The stock system comes with AmigaOS version 1.2 or 1.3 and of chip RAM (150 ns access time), one built-in double-density standard floppy disk drive that is completely programmable and can read IBM PC disks, standard Amiga disks, and up to using custom-formatting drivers. Despite the lack of Amiga 2000-compatible internal expansion slots, there are many ports and expansion options. There are two DE9M Atari joystick ports for joysticks or mice, and stereo audio RCA connectors (1 V p-p). There is a floppy drive port for daisy-chaining up to three extra floppy disk drives via a DB23F connector. The then-standard RS-232 serial port (DB25M) and Centronics parallel port (DB25F) are also included. The power supply is (, ). The system displays video in analog RGB PAL or NTSC through a proprietary DB23M connector and in NTSC mode the line frequency is HSync for standard video modes, which is compatible with NTSC television and CVBS/RGB video, but out of range for most VGA-compatible monitors, while a multisync monitor is required for some of the higher resolutions. This connection can also be genlocked to an external video signal. The system was bundled with an RF adapter to provide output on televisions with a coaxial RF input, while monochrome video is available via an RCA connector (also coaxial). On the left side, behind a plastic cover, there is a Zorro (Zorro I) bus expansion external edge connector with 86 pins. Peripherals such as a hard disk drive can be added via the expansion slot and are configured automatically by the Amiga's AutoConfig standard, so that multiple devices do not conflict with each other. Up to of so-called "fast RAM" (memory that can be accessed by the CPU only) can be added using the side expansion slot. This connector is electronically identical with the Amiga 1000's, but swapped on the other side. The Amiga 500 has a "trap-door" slot on the underside for a RAM upgrade (typically ). This extra RAM is classified as "fast" RAM, but is sometimes referred to as "slow" RAM: due to the design of the expansion bus, it is actually on the chipset bus. Such upgrades usually include a battery-backed real-time clock. All versions of the A500 can have the additional RAM configured as chip RAM by a simple hardware modification, which involves fitting a later model (8372A) Agnus chip. Likewise, all versions of the A500 can be upgraded to chip RAM by fitting the chip and adding additional memory. The Amiga 500 also sports an unusual feature for a budget machine, socketed chips, which allow easy replacement of defective chips. The CPU can be directly upgraded on the motherboard to a 68010; or to a 68020, 68030, or 68040 via the side expansion slot; or by removing the CPU and plugging a CPU expansion card into the CPU socket (this requires opening the computer and thus voided any remaining warranty). In fact, all the custom chips can be upgraded to the Amiga Enhanced Chip Set (ECS) versions. The plastic case is made of acrylonitrile butadiene styrene, or ABS. ABS degrades with time due to exposure to oxygen, causing a yellowing of the case. Other factors contributing to the degradation and yellowing include heat, shear, and ultraviolet light. The yellowing can be reversed by using an optical brightener, though without stabilizing agents or antioxidants to block oxygen, the yellowing will return. Technical specifications OCS (1.2 & 1.3 models) or ECS (1.3 and 500+ 2.04 models) chipset. ECS revisions of the chipset made PAL/NTSC mode switchable in software. Sound: 4 hardware-mixed channels of 8-bit sound at up to . The hardware channels have independent volumes (65 levels) and sampling rates, and are mixed down to two fully left and fully right stereo outputs. A software controllable low-pass audio filter is also included. 512 KB of chip RAM (150 ns access time) AmigaOS 1.2 or 1.3 (upgradeable up to 3.1.4 if 2 MB of RAM are installed) One 3.5" double-density floppy disk drive is built in, which is completely programmable and thus can read IBM PC disks, standard Amiga disks, and up to with custom formatting (such as Klaus Deppich's diskspare.device). Uses (5 rotations/second) and . Built-in keyboard A two-button mouse is included. Graphics PAL mode: 768×580 maximum (overscan interlaced if viewed on composite monitor/TV). Typical resolutions: 320×256, 640×256 or 640×512 (all displayed with borders). NTSC mode: 768×484 maximum (overscan interlaced if viewed on composite monitor/TV). Typical resolutions: 320×200, 640×200 or 640×400 (all displayed with borders). Graphics can be of arbitrary dimensions, resolution and colour depth, even on the same screen. The Amiga can show multiple resolution modes at the same time, splitting the screen vertically. Planar graphics are used, with up to 5 bitplanes (4 in hires); this allowed 2, 4, 8, 16 and 32 colour screens, from a palette of 4096 colours. Two special graphics modes are also included: Extra Half Brite (EHB), which uses a 6th bitplane as a mask that halved the brightness of any colour seen Hold-And-Modify (HAM), which allows all 4096 colours on screen at once. HAM makes it possible to use over a wide span. This works by letting each pixel position use the previous RGB value and modify one of the red, green or blue values to a new 4-bit value. This will cause some negligible colour artifacts however. Memory Using various expansion techniques, the A500's total RAM can reach up to 138 MB – 2 MB Chip RAM, 8 MB 16-bit Fast RAM, and 128 MB 32-bit Fast RAM. Chip RAM The stock 512 KB Chip RAM can be complemented by 512 KB using a "trapdoor" expansion (Commodore A501 or compatible). While that expansion memory is connected to the chip bus, hardware limitations of early stock Agnus chip revisions prevent its use as Chip RAM, only the CPU can access it. Suffering from the same contention limitations as Chip RAM, that memory is known as "Slow RAM" or "Pseudo-fast RAM". Agnus revisions shipped with late A500 are ECS and allow use of trapdoor RAM as real Chip RAM for a total 1 MB. Additionally, several third-party expansions exist with up to 2 MB on the trapdoor board. Using a Gary adapter, that memory will be mapped as either split on Chip RAM and Slow RAM or fully as Slow RAM, depending on configuration. Furthermore, using an A3000 Agnus on an adapter board, it is possible to expand the Chip RAM to 2 MB, matching the A500+. Fast RAM "Fast" RAM is located on the CPU-side bus. Its access is exclusive to the CPU and not slowed by any chipset access. The side expansion port allows for up to 8 MB of Zorro-style expansion RAM. Alternatively, a CPU adapter allows for internal expansion. Accelerator RAM Internal or external CPU accelerators often include their own expansion memory. 16-bit CPUs are limited by the 24-bit address space but they can repurpose otherwise unused memory space for their included RAM. 32-bit CPU accelerators aren't limited by 24-bit addressing and can include up to 128 MB of Fast RAM (and potentially more). Memory map Connectors Two Atari joystick ports for joysticks or mice Stereo audio RCA connectors ( p-p) A floppy drive port (DB23F), for daisy-chaining up to 3 extra floppy disk drives via a DB23F connector A standard RS-232 serial port (DB25M) A parallel port (DB25F) Power inlet (, ) Analogue RGB PAL and NTSC video output, provided on an Amiga-specific DB23M video connector. Can drive video with HSync for standard Amiga video modes. This is not compatible with most VGA monitors. A Multisync monitor is required for some higher resolutions. This connection can also be genlocked to an external video signal. An RF adapter (A520) was frequently bundled with the machine to provide output on regular televisions or on composite monitors. A digital 16 colour Red-Green-Blue-Intensity signal is available too on the same connector. Monochrome video via an RCA connector Zorro II bus expansion on the left side behind a plastic cover Trapdoor slot under the machine, for RAM expansion and real-time clock Expansions Expansion ports are limited to a side expansion port and a trapdoor expansion on the underside of the machine. The casing can also be opened up (voiding the warranty), all larger chips are socketed rather than being TH/SMD soldered directly to the motherboard, so they can be replaced by hand. The CPU can be upgraded to a Motorola 68010 directly or to a 68020, 68030 or 68040 via the side expansion slot or a CPU socket adapter board. The chip RAM can be upgraded to directly on the motherboard, provided a Fat Agnus chip is also installed to support it. Likewise, all the custom chips can be upgraded to the ECS chipset. The A500+ model instead allowed upgrading by trapdoor chip RAM without clock, but there was no visible means on board to map any of this as FAST, causing incompatibility with some stubbornly coded programs. There were modification instructions available for the A500 to solder or socket another RAM on the board, then run extra address lines to the trapdoor slot to accommodate an additional of fast or chip RAM depending on the installed chipset. Up to of "fast RAM" can be added via the side expansion slot, even more if an accelerator with a non-EC (without reduced data/address bus) processor and 32-bit RAM is used. Hard drive and other peripherals can be added via the side expansion slot. Several companies provided combined CPU, memory and hard drive upgradesor provided chainable expansions that extended the bus as they were addedas there is only one side expansion slot. Expansions are configured automatically by AutoConfig software, so multiple pieces of hardware did not conflict with each other. Diagnostics When the computer is powered on a self-diagnostic test is run that will indicates failure with a specific colour: Medium green means no chip RAM found or is damaged. Red means bad kickstart-ROM. Yellow means the CPU has crashed (no trap routine or trying to run bad code) or a bad Zorro expansion card. Blue means a custom chip problem (Denise, Paula, or Agnus). Light green means CIA problem. Light gray means that the CIA might be defective. mean there is a ROM or CIA problem. Black-only (no video) means there is no video output. The keyboard LED uses blink codes: One blink means the keyboard ROM has a checksum error. Two blinks means RAM failure. Three blinks means watchdog timer failure. Measurements Overall (base): 6.2 cm x 47.4 cm x 33 cm; 2 7/16 in x 18 11/16 in x 13 in. Trap-door expansion 501 A popular expansion for the Amiga 500 was the Amiga 501 circuit board that can be installed underneath the computer behind a plastic cover. The expansion contains RAM configured by default as "Slow RAM" or "trap-door RAM" and a battery-backed real-time clock (RTC). The 512 KB trap-door RAM and 512 KB of original chip RAM will result in 1 MB of total memory. The added memory is known as "Slow RAM", as its access is impacted by chip-bus bandwidth contention, while the chipset is not actually able to address it. Later revisions of the motherboard provide solder-jumpers to relocate the trap-door RAM to the chip memory pool, given the Agnus chip is the newer ECS version, shipped in later A500 motherboards. Newest (rev 8) A500s would share motherboard with A500+, and configure the expansion memory as CHIP by default. Software Each time the Amiga 500 is booted, it executes code from the Kickstart ROM. The Amiga 500 initially came shipped with AmigaOS 1.2, but units since October 1988 had version 1.3 installed. Reception and sales The Amiga 500 was the best-selling model in the Amiga family of computers. The German computer magazine Chip awarded the model the annual "Home Computer of the Year" title three consecutive times. At the European Computer Trade Show 1991, it also won the Leisure Award for the similar "Home Computer of the Year" title. Owing to the inexpensive cost of the Amiga 500 in then price-sensitive Europe, sales of the Amiga family of computers were strongest there, constituting 85 percent of Commodore's total sales in the fourth quarter of 1990. The Amiga 500 was widely perceived as a gaming machine and the Amiga 2000 a computer for artists and hobbyists. It has been claimed that Commodore sold as many as six million units worldwide. However, Commodore UK refuted that figure and said that the entire Amiga line sold between four and five million computers. Indeed, Ars Technica provides a year-by-year graph of the sales of all Amiga computers. The machine is reported to have sold 1,160,500 units in Germany (including Amiga 500 Plus sales). Amiga 500 Plus The Amiga 500 Plus (often A500 Plus or simply A500+) is a revised version of the original Amiga 500 computer. The A500+ featured minor changes to the motherboard to make it cheaper to produce than the original A500. It was notable for introducing new versions of Kickstart and Workbench, and for some minor improvements in the custom chips, known as the Enhanced Chip Set (or ECS). Although officially introduced in 1992, some Amiga 500 units sold in late 1991 actually featured the revised motherboard used in the A500+. Although the Amiga 500+ was an improvement to the Amiga 500, it was minor. It was discontinued and replaced by the Amiga 600 in summer 1992, making it the shortest-lived Amiga model. Compatibility problems Due to the new Kickstart v2.04, quite a few popular games (such as Treasure Island Dizzy, Lotus Esprit Turbo Challenge, and SWIV) failed to work on the Amiga 500+, and some people took them back to dealers demanding an original Kickstart 1.3 Amiga 500. This problem was largely solved by third parties who produced Kickstart ROM switching boards, that could allow the Amiga 500+ to be downgraded to Kickstart 1.2 or 1.3. It also encouraged game developers to use better programming habits, which was important since Commodore already had plans for the introduction of the next-generation Amiga 1200 computer. A program, Relokick, was also released (and included with an issue of CU Amiga) which loaded a Kickstart 1.3 ROM image into memory and booted the machine into Kickstart 1.3, allowing most incompatible software to run (the software did take up 512 KB of system memory, meaning that some 1 MB only games would now fail for lack of available memory). In some cases, updated compatible versions of games were later released, such as budget versions of Lotus 1 and SWIV, and an update to Bubble Bobble. Double Dragon 2 by Binary Design received an update for ECS machines with the "Amiga phase-alternated linescan version 4.01/ECS". This solved compatibility issues with the graphics which appeared garbled on ECS machines, and it also slashed the in-game loading times from around 20 seconds to just over 6.

Amiga 1000

The Amiga 1000, also known as the A1000, is the first personal computer released by Commodore International in the Amiga line. It combines the 16/32-bit Motorola 68000 CPU which was powerful by 1985 standards with one of the most advanced graphics and sound systems in its class. It runs a preemptive multitasking operating system that fits into of read-only memory and was shipped with 256 KB of RAM. The primary memory can be expanded internally with a manufacturer-supplied 256 KB module for a total of 512 KB of RAM. Using the external slot the primary memory can be expanded up to Design The A1000 has a number of characteristics that distinguish it from later Amiga models: It is the only model to feature the short-lived Amiga check-mark logo on its case, the majority of the case is elevated slightly to give a storage area for the keyboard when not in use (a "keyboard garage"), and the inside of the case is engraved with the signatures of the Amiga designers (similar to the Macintosh); including Jay Miner and the paw print of his dog Mitchy. The A1000's case was designed by Howard Stolz. As Senior Industrial Designer at Commodore, Stolz was the mechanical lead and primary interface with Sanyo in Japan, the contract manufacturer for the A1000 casing. The Amiga 1000 was manufactured in two variations: One uses the NTSC television standard and the other uses the PAL television standard. The NTSC variant was the initial model manufactured and sold in North America. The later PAL model was manufactured in Germany and sold in countries using the PAL television standard. The first NTSC systems lack the EHB video mode which is present in all later Amiga models. Because AmigaOS was rather buggy at the time of the A1000's release, the OS was not placed in ROM then. Instead, the A1000 includes a daughterboard with 256 KB of RAM, dubbed the "writable control store" (WCS), into which the core of the operating system is loaded from floppy disk (this portion of the operating system is known as the "Kickstart"). The WCS is write-protected after loading, and system resets do not require a reload of the WCS. In Europe, the WCS was often referred to as WOM (Write Once Memory), a play on the more conventional term "ROM" (read-only memory). Technical information The preproduction Amiga (which was codenamed "Velvet") released to developers in early 1985 contained of RAM with an option to expand it to Commodore later increased the system memory to due to objections by the Amiga development team. The names of the custom chips were different; Denise and Paula were called Daphne and Portia respectively. The casing of the preproduction Amiga was almost identical to the production version: the main difference being an embossed Commodore logo in the top left corner. It did not have the developer signatures. The Amiga 1000 has a Motorola 68000 CPU running at 7.15909 MHz on NTSC systems or 7.09379 MHz on PAL systems, precisely double the video color carrier frequency for NTSC or 1.6 times the color carrier frequency for PAL. The system clock timings are derived from the video frequency, which simplifies glue logic and allows the Amiga 1000 to make do with a single crystal. In keeping with its video game heritage, the chipset was designed to synchronize CPU memory access and chipset DMA so the hardware runs in real time without wait-state delays. Though most units were sold with an analog RGB monitor, the A1000 also has a built-in composite video output which allows the computer to be connected directly to some monitors other than their standard RGB monitor. The A1000 also has a "TV MOD" output, into which an RF Modulator can be plugged, allowing connection to older televisions that did not have a composite video input. The original 68000 CPU can be directly replaced with a Motorola 68010, which can execute instructions slightly faster than the 68000 but also introduces a small degree of software incompatibility. Third-party CPU upgrades, which mostly fit in the CPU socket, use faster 68020 or 68030 microprocessors and integrated memory, as well as provide support for a 68881 or 68882 FPU. Such upgrades often have the option to revert to 68000 mode for full compatibility. Some boards have a socket to seat the original 68000, whereas the 68030 cards typically come with an on-board 68000. The original Amiga 1000 is the only model to have 256 KB of Amiga Chip RAM, which can be expanded to 512 KB with the addition of a daughterboard under a cover in the center front of the machine. RAM may also be upgraded via official and third-party upgrades, with a practical upper limit of about 9 MB of "fast RAM" due to the 68000's 24-bit address bus. This memory is accessible only by the CPU permitting faster code execution as DMA cycles are not shared with the chipset. The Amiga 1000 features an 86-pin expansion port (electrically identical to the later Amiga 500 expansion port, though the A500's connector is inverted). This port is used by third-party expansions such as memory upgrades and SCSI adapters. These resources are handled by the Amiga Autoconfig standard. Other expansion options are available including a bus expander which provides two Zorro-II slots. Specifications Retail Introduced on July 23, 1985, during a star-studded gala featuring Andy Warhol and Debbie Harry held at the Vivian Beaumont Theater at Lincoln Center in New York City, machines began shipping in September with a base configuration of 256 KB of RAM at the retail price of . A analog RGB monitor was available for around , bringing the price of a complete Amiga system to US$1,595 (). Before the release of the Amiga 500 and Amiga 2000 models in 1987, the A1000 was marketed as simply the Amiga, although the model number was there from the beginning, as the original box indicates. In the US, the A1000 was marketed as The Amiga from Commodore, with the Commodore logo omitted from the case. The Commodore branding was retained for the international versions. Additionally, the Amiga 1000 was sold exclusively in computer stores in the US rather than the various non computer-dedicated department and toy stores through which the VIC-20 and Commodore 64 were retailed. These measures were an effort to avoid Commodore's "toy-store" computer image created during the Tramiel era. Along with the operating system, the machine came bundled with a version of AmigaBASIC developed by Microsoft and a speech synthesis library developed by Softvoice, Inc. Aftermarket upgrades Many A1000 owners remained attached to their machines long after newer models rendered the units technically obsolete, and it attracted numerous aftermarket upgrades. Many CPU upgrades that plugged into the Motorola 68000 socket functioned in the A1000. Additionally, a line of products called the Rejuvenator series allowed the use of newer chipsets in the A1000, and an Australian-designed replacement A1000 motherboard called The Phoenix utilized the same chipset as the A3000 and added an A2000-compatible video slot and on-board SCSI controller. Reception and impact In its product preview, Byte magazine was impressed by the computer's multitasking capabilities and the quality of its graphics and sound systems. It also praised its text-to-speech library for voice output, and predicted that the Amiga would be successful enough to influence the personal computer industry. The Amiga 1000 was released to positive reviews. Compute! lauded it as an inexpensive, truly general-purpose computer that might break preconceptions dividing the microcomputer marketplace. In this case, it was capable of outperforming most business, as well as arcade game machines and delivering sampled sound, making it suitable for offices, gamers, and digital artists. Computer Gaming World praised the machine's versatility without any obvious hardware shortcomings and stressed that it was ideal for game designers demanding fewer system constraints. Creative Computing magazine had only minor criticisms for what they otherwise called a "dream machine." These criticisms were directed toward its case quality, the disk drives slowing during certain operations, and not finding an AUTOEXEC command in AmigaDOS, though the marketing vice president of Commodore, Clive Smith, assured the magazine that later production units would address most of its complaints. Months after the Amiga 1000 was released, InfoWorld offered a mixed review. It praised Intuition and the customizability of Workbench, but took issue with the operating system's bugs such as memory overflow and screen flickering of single lines as a result of their being interleaved when displayed in high resolution mode. It also criticized the sparseness of the software library preventing the publication from fully realizing the computer's potential. In 1994, as Commodore filed for bankruptcy, Byte magazine called the Amiga 1000 "the first multimedia computer... so far ahead of its time that almost nobody—including Commodore's marketing department—could fully articulate what it was all about". In 2006, PC World rated the Amiga 1000 as the 7th greatest PC of all time. In 2007, it was rated by the same magazine as the 37th best tech product of all time. Also that year, IDG Sweden ranked it the 10th best computer of all time. Joe Pillow "Joe Pillow" was the name given on the ticket for the extra airline seat purchased to hold the first Amiga prototype while on the way to the January 1984 Consumer Electronics Show. The airlines required a name for the airline ticket and Joe Pillow was born. The engineers (RJ Mical and Dale Luck) who flew with the Amiga prototype (codenamed Lorraine) drew a happy face on the front of the pillowcase and even added a tie. Joe Pillow extended his fifteen minutes of fame when the Amiga went to production. All fifty-three Amiga team members who worked on the project signed the Amiga case. This included Joe Pillow and Jay Miner's dog Michy who each got to "sign" the case in their own unique way.

Andrew S. Tanenbaum

Andrew Stuart Tanenbaum (born March 16, 1944), sometimes referred to by the handle ast, is an American-Dutch computer scientist and professor emeritus of computer science at the Vrije Universiteit Amsterdam in the Netherlands. He is the author of MINIX, a free Unix-like operating system for teaching purposes, and has written multiple computer science textbooks regarded as standard texts in the field. He regards his teaching job as his most important work. Since 2004 he has operated Electoral-vote.com, a website dedicated to analysis of polling data in federal elections in the United States. Biography Tanenbaum was born in New York City and grew up in suburban White Plains, New York, where he attended the White Plains High School. He is Jewish. His paternal grandfather was born in Khorostkiv in the Austro-Hungarian empire. He received his Bachelor of Science degree in physics from MIT in 1965 and his PhD degree in astrophysics from the University of California, Berkeley in 1971. Tanenbaum also served as a lobbyist for the Sierra Club. He moved to the Netherlands to live with his wife, who is Dutch, but he retains his United States citizenship. He taught courses on Computer Organization and Operating Systems and supervised the work of PhD candidates at the VU University Amsterdam. On July 9, 2014, he announced his retirement. Teaching Books Tanenbaum's textbooks on computer science include: Structured Computer Organization (1976) Computer Networks, co-authored with David J. Wetherall and Nickolas Feamster (1981) Operating Systems: Design and Implementation, co-authored with Albert Woodhull (1987) Modern Operating Systems (1992) Distributed Operating Systems (1994) Distributed Systems: Principles and Paradigms, co-authored with Maarten van Steen (2001) His book, Operating Systems: Design and Implementation and MINIX were Linus Torvalds' inspiration for the Linux kernel. In his autobiography Just for Fun, Torvalds describes it as "the book that launched me to new heights". His books have been translated into many languages including Arabic, Basque, Bulgarian, Chinese, Dutch, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Korean, Macedonian, Mexican Spanish, Persian, Polish, Portuguese, Romanian, Russian, Serbian, and Spanish. They have appeared in over 175 editions and are used at universities around the world. Doctoral students Tanenbaum has had a number of PhD students who themselves have gone on to become widely known computer science researchers. These include: Henri Bal, professor at the Vrije Universiteit in Amsterdam Frans Kaashoek, professor at MIT Werner Vogels, Chief Technology Officer at Amazon.com Dean of the Advanced School for Computing and Imaging In the early 1990s, the Dutch government began setting up a number of thematically oriented research schools that spanned multiple universities. These schools were intended to bring professors and PhD students from different Dutch (and later, foreign) universities together to help them cooperate and enhance their research. Tanenbaum was one of the cofounders and first Dean of the Advanced School for Computing and Imaging (ASCI). This school initially consisted of nearly 200 faculty members and PhD students from the Vrije Universiteit, University of Amsterdam, Delft University of Technology, and Leiden University. They were especially working on problems in advanced computer systems such as parallel computing and image analysis and processing. Tanenbaum remained dean for 12 years, until 2005, when he was awarded an Academy Professorship by the Royal Netherlands Academy of Arts and Sciences, at which time he became a full-time research professor. ASCI has since grown to include researchers from nearly a dozen universities in The Netherlands, Belgium, and France. ASCI offers PhD level courses, has an annual conference, and runs various workshops every year. Projects Amsterdam Compiler Kit The Amsterdam Compiler Kit is a toolkit for producing portable compilers. It was started sometime before 1981 and Andrew Tanenbaum was the architect from the start until version 5.5. MINIX In 1987, Tanenbaum wrote a clone of UNIX, called MINIX (MINi-unIX), for the IBM PC. It was targeted at students and others who wanted to learn how an operating system worked. Consequently, he wrote a book that listed the source code in an appendix and described it in detail in the text. The source code itself was available on a set of floppy disks. Within three months, a Usenet newsgroup, comp.os.minix, had sprung up with over 40,000 subscribers discussing and improving the system. One of these subscribers was a Finnish student named Linus Torvalds, who began adding new features to MINIX and tailoring it to his own needs. On October 5, 1991, Torvalds announced his own (POSIX-like) kernel, called Linux, which originally used the MINIX file system but is not based on MINIX code. Although MINIX and Linux have diverged, MINIX continues to be developed, now as a production system as well as an educational one. The focus is on building a highly modular, reliable, and secure operating system. The system is based on a microkernel, with only 5000 lines of code running in kernel mode. The rest of the operating system runs as a number of independent processes in user mode, including processes for the file system, process manager, and each device driver. The system continuously monitors each of these processes, and when a failure is detected is often capable of automatically replacing the failed process without a reboot, without disturbing running programs, and without the user even noticing. MINIX 3, as the current version is called, is available under the BSD license for free. In 2017, Google discovered that the Intel Management Engine runs MINIX in ring -3. After Tanenbaum read about this, he published an open letter to Intel, detailing conversations with Intel software engineers that occurred several years ago, where they wanted his assistance in modifying MINIX to work on "some secret project". He believes that Intel chose MINIX for this purpose because it is licensed under the BSD-3-Clause license, which allowed Intel to modify the MINIX source code without freely distributing their modified version. In his letter, Tanenbaum claims that MINIX is the most widespread operating system, and this is interpreted by the community as Tanenbaum believing that he has won the Tanenbaum–Torvalds debate. It is hard to know if MINIX or Linux is more popular, as Intel does not publish chipset sales figures, and there is no direct way to find the number of systems running Linux or MINIX. However, Linux has seen much more widespread use in the server space, is widely used in embedded systems, and also runs on all Android phones, which account for at least 3 billion active devices, meaning that it is likely that Linux is the most widespread operating system, although there is no concrete data to back up this claim. Research projects Tanenbaum has also been involved in numerous other research projects in the areas of operating systems, distributed systems, and ubiquitous computing, often as supervisor of PhD students or a postdoctoral researcher. These projects include: Amoeba Globe Mansion Orca Paramecium RFID Guardian Turtle F2F Electoral-vote.com In 2004, Tanenbaum created Electoral-vote.com, a web site analyzing opinion polls for the 2004 U.S. Presidential Election, using them to project the outcome in the Electoral College. He stated that he created the site as an American who "knows first hand what the world thinks of America and it is not a pretty picture at the moment. I want people to think of America as the land of freedom and democracy, not the land of arrogance and blind revenge. I want to be proud of America again." The site provided a color-coded map, updated each day with projections for each state's electoral votes. Through most of the campaign period Tanenbaum kept his identity secret, referring to himself as "the Votemaster" and acknowledging only that he personally preferred John Kerry. Mentioning that he supported the Democrats, he revealed his identity on November 1, 2004, the day before the election, and also stating his reasons and qualifications for running the website. Through the site he also covered the 2006 midterm elections, correctly predicting the winner of all 33 Senate races that year. For the 2008 elections, he got every state right except for Indiana, which he said McCain would win by 2% (Obama won by 1%) and Missouri, which he said was too close to call (McCain won by 0.1%). He correctly predicted all the winners in the Senate except for Minnesota, where he predicted a 1% win by Norm Coleman over Al Franken. After 7 months of legal battling and recounts, Franken won by 312 votes (0.01%). In 2010, he correctly projected 35 out of 37 Senate races in the Midterm elections on the website. The exceptions were Colorado and Nevada. Electoral-vote.com incorrectly predicted Hillary Clinton would win the 2016 United States presidential election. The website incorrectly predicted Clinton would win Wisconsin, Michigan, Pennsylvania, North Carolina, and Florida. Electoral-vote.com did not predict a winner for Nevada, which Clinton would win. The website predicted the winners of the remaining 44 states and the District of Columbia correctly.

Ariane 5

Ariane 5 was a retired European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It was launched from the Centre Spatial Guyanais (CSG) in French Guiana. It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development. The system was designed as an expendable launch system by the Centre national d'études spatiales (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it was classified as part of the Ariane rocket family. ArianeGroup was the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally intended to launch the Hermes spacecraft, and thus it was rated for human space launches. Since its first launch, Ariane 5 was refined in successive versions: "G", "G+", "GS", "ECA", and finally, "ES". The system had a commonly used dual-launch capability, where up to two large geostationary belt communication satellites can be mounted using a SYLDA (Système de Lancement Double Ariane, meaning "Ariane Double-Launch System") carrier system. Up to three, somewhat smaller, main satellites are possible depending on size using a SPELTRA (Structure Porteuse Externe Lancement Triple Ariane, which translates to "Ariane Triple-Launch External Carrier Structure"). Up to eight secondary payloads, usually small experiment packages or minisatellites, could be carried with an ASAP (Ariane Structure for Auxiliary Payloads) platform. Following the launch of 15 August 2020, Arianespace signed the contracts for the last eight Ariane 5 launches, before it was succeeded by the new Ariane 6 launcher, according to Daniel Neuenschwander, director of space transportation at the ESA. Ariane 5 flew its final mission on 5 July 2023. Vehicle description Cryogenic main stage Ariane 5's cryogenic H173 main stage (H158 for Ariane 5G, G+, and GS) was called the EPC (Étage Principal Cryotechnique — Cryotechnic Main Stage). It consisted of a diameter by high tank with two compartments, one for liquid oxygen and one for liquid hydrogen, and a Vulcain 2 engine at the base with a vacuum thrust of . The H173 EPC weighed about , including of propellant. After the main cryogenic stage runs out of fuel, it re-entered the atmosphere for an ocean splashdown. Solid boosters Attached to the sides were two P241 (P238 for Ariane 5G and G+) solid rocket boosters (SRBs or EAPs from the French Étages d'Accélération à Poudre), each weighing about full and delivering a thrust of about . They were fueled by a mix of ammonium perchlorate (68%) and aluminium fuel (18%) and HTPB (14%). They each burned for 130 seconds before being dropped into the ocean. The SRBs were usually allowed to sink to the bottom of the ocean, but, like the Space Shuttle Solid Rocket Boosters, they could be recovered with parachutes, and this was occasionally done for post-flight analysis. Unlike Space Shuttle SRBs, Ariane 5 boosters were not reused. The most recent attempt was for the first Ariane 5 ECA mission in 2009. One of the two boosters was successfully recovered and returned to the Guiana Space Center for analysis. Prior to that mission, the last such recovery and testing was done in 2003. The French M51 submarine-launched ballistic missile (SLBM) shared a substantial amount of technology with these boosters. In February 2000, the suspected nose cone of an Ariane 5 booster washed ashore on the South Texas coast, and was recovered by beachcombers before the government could get to it. Second stage The second stage was on top of the main stage and below the payload. The original Ariane — Ariane 5G — used the EPS (Étage à Propergols Stockables — Storable Propellant Stage), which was fueled by monomethylhydrazine (MMH) and nitrogen tetroxide, containing of storable propellant. The EPS was subsequently improved for use on the Ariane 5G+, GS, and ES. The EPS upper stage was capable of repeated ignition, first demonstrated during flight V26 which was launched on 5 October 2007. This was purely to test the engine, and occurred after the payloads had been deployed. The first operational use of restart capability as part of a mission came on 9 March 2008, when two burns were made to deploy the first Automated Transfer Vehicle (ATV) into a circular parking orbit, followed by a third burn after ATV deployment to de-orbit the stage. This procedure was repeated for all subsequent ATV flights. Ariane 5ECA used the ESC (Étage Supérieur Cryotechnique — Cryogenic Upper Stage), which was fueled by liquid hydrogen and liquid oxygen. The ESC used the HM7B engine previously used in the Ariane 4 third stage. The propellent load of 14.7 tonne allowed the engine to burn for 945 seconds while providing 6.5 tonne of thrust. The ESC provided roll control during powered flight and full attitude control during payload separation using hydrogen gas thrusters. Oxygen gas thrusters allowed longitudinal acceleration after engine cutoff. The flight assembly included the Vehicle Equipment Bay, with flight electronics for the entire rocket, and the payload interface and structural support. Fairing The payload and all upper stages were covered at launch by a fairing for aerodynamic stability and protection from heating during supersonic flight and acoustic loads. It was jettisoned once sufficient altitude has been reached, typically above . It was made by Ruag Space and since flight VA-238 it was composed of 4 panels. Variants Launch system status: Launch pricing and market competition , the Ariane 5 commercial launch price for launching a "midsize satellite in the lower position" was approximately €50 million, competing for commercial launches in an increasingly competitive market. The heavier satellite was launched in the upper position on a typical dual-satellite Ariane 5 launch and was priced higher than the lower satellite, on the order of €90 million . Total launch price of an Ariane 5 – which could transport up to two satellites to space, one in the "upper" and one in the "lower" positions – was around €150 million . Cancelled plans for future developments Ariane 5 ME The Ariane 5 ME (Mid-life Evolution) was in development into early 2015, and was seen as a stopgap between Ariane 5ECA/Ariane 5ES and the new Ariane 6. With first flight planned for 2018, it would have become ESA's principal launcher until the arrival of the new Ariane 6 version. ESA halted funding for the development of Ariane 5ME in late 2014 to prioritize development of Ariane 6. The Ariane 5ME was to use a new upper stage, with increased propellant volume, powered by the new Vinci engine. Unlike the HM-7B engine, it was to be able to restart several times, allowing for complex orbital maneuvers such as insertion of two satellites into different orbits, direct insertion into geosynchronous orbit, planetary exploration missions, and guaranteed upper stage deorbiting or insertion into graveyard orbit. The launcher was also to include a lengthened fairing up to and a new dual launch system to accommodate larger satellites. Compared to an Ariane 5ECA model, the payload to GTO was to increase by 15% to and the cost-per-kilogram of each launch was projected to decline by 20%. Development Originally known as the Ariane 5ECB, Ariane 5ME was to have its first flight in 2006. However, the failure of the first ECA flight in 2002, combined with a deteriorating satellite industry, caused ESA to cancel development in 2003. Development of the Vinci engine continued, though at a lower pace. The ESA Council of Ministers agreed to fund development of the new upper stage in November 2008. In 2009, EADS Astrium was awarded a €200 million contract, and on 10 April 2012 received another €112 million contract to continue development of the Ariane 5ME with total development effort expected to cost €1 billion. On 21 November 2012, ESA agreed to continue with the Ariane 5ME to meet the challenge of lower priced competitors. It was agreed the Vinci upper stage would also be used as the second stage of a new Ariane 6, and further commonality would be sought. Ariane 5ME qualification flight was scheduled for mid-2018, followed by gradual introduction into service. On 2 December 2014, ESA decided to stop funding the development of Ariane 5ME and instead focus on Ariane 6, which was expected to have a lower cost per launch and allow more flexibility in the payloads (using two or four P120C solid boosters depending on total payload mass). Solid propellant stage Work on the Ariane 5 EAP motors was continued in the Vega programme. The Vega 1st stage engine – the P80 engine – was a shorter derivation of the EAP. The P80 booster casing was made of filament wound graphite epoxy, much lighter than the current stainless steel casing. A new composite steerable nozzle was developed while new thermal insulation material and a narrower throat improved the expansion ratio and subsequently the overall performance. Additionally, the nozzle had electromechanical actuators which replaced the heavier hydraulic ones used for thrust vector control. These developments could maybe have made their way back into the Ariane programme, but this was most likely an inference based on early blueprints of the Ariane 6 having a central P80 booster and 2-4 around the main one. The incorporation of the ESC-B with the improvements to the solid motor casing and an uprated Vulcain engine would have delivered to LEO. This would have been developed for any lunar missions but the performance of such a design might not have been possible if the higher Max-Q for the launch of this launch vehicle would have posed a constraint on the mass delivered to orbit. Ariane 6 The design brief of the next generation launch vehicle Ariane 6 called for a lower-cost and smaller launch vehicle capable of launching a single satellite of up to to GTO. However, after several permutations the finalized design was nearly identical in performance to the Ariane 5, focusing instead on lowering fabrication costs and launch prices. , Ariane 6 was projected to be launched for about €70 million per flight, about half of the Ariane 5 price. Initially development of Ariane 6 was projected to cost €3.6 billion. In 2017, the ESA set 16 July 2020 as the deadline for the first flight. As of June 2022, Arianespace expects the maiden flight to occur in 2023. Notable launches Ariane 5's first test flight (Ariane 5 Flight 501) on 4 June 1996 failed, with the rocket self-destructing 37 seconds after launch because of a malfunction in the control software. A data conversion from 64-bit floating-point value to 16-bit signed integer value to be stored in a variable representing horizontal bias caused a processor trap (operand error) because the floating-point value was too large to be represented by a 16-bit signed integer. The software had been written for the Ariane 4 where efficiency considerations (the computer running the software had an 80% maximum workload requirement) led to four variables being protected with a handler while three others, including the horizontal bias variable, were left unprotected because it was thought that they were "physically limited or that there was a large margin of safety". The software, written in Ada, was included in the Ariane 5 through the reuse of an entire Ariane 4 subsystem despite the fact that the particular software containing the bug, which was just a part of the subsystem, was not required by the Ariane 5 because it has a different preparation sequence than the Ariane 4. The second test flight (L502, on 30 October 1997) was a partial failure. The Vulcain nozzle caused a roll problem, leading to premature shutdown of the core stage. The upper stage operated successfully, but it could not reach the intended orbit. A subsequent test flight (L503, on 21 October 1998) proved successful and the first commercial launch (L504) occurred on 10 December 1999 with the launch of the XMM-Newton X-ray observatory satellite. Another partial failure occurred on 12 July 2001, with the delivery of two satellites into an incorrect orbit, at only half the height of the intended GTO. The ESA Artemis telecommunications satellite was able to reach its intended orbit on 31 January 2003, through the use of its experimental ion propulsion system. The next launch did not occur until 1 March 2002, when the Envisat environmental satellite successfully reached an orbit of above the Earth in the 11th launch. At , it was the heaviest single payload until the launch of the first ATV on 9 March 2008, at . The first launch of the ECA variant on 11 December 2002 ended in failure when a main booster problem caused the rocket to veer off-course, forcing its self-destruction three minutes into the flight. Its payload of two communications satellites (STENTOR and Hot Bird 7), valued at about €630 million, was lost in the Atlantic Ocean. The fault was determined to have been caused by a leak in coolant pipes allowing the nozzle to overheat. After this failure, Arianespace SA delayed the expected January 2003 launch for the Rosetta mission to 26 February 2004, but this was again delayed to early March 2004 due to a minor fault in the foam that protects the cryogenic tanks on the Ariane 5. The failure of the first ECA launch was the last failure of an Ariane 5 until flight 240 in January 2018. On 27 September 2003, the last Ariane 5G boosted three satellites (including the first European lunar probe, SMART-1), in Flight 162. On 18 July 2004, an Ariane 5G+ boosted what was at the time the heaviest telecommunication satellite ever, Anik F2, weighing almost . The first successful launch of the Ariane 5ECA took place on 12 February 2005. The payload consisted of the XTAR-EUR military communications satellite, a 'SLOSHSAT' small scientific satellite and a MaqSat B2 payload simulator. The launch had been scheduled for October 2004, but additional testing and a military launch (of a Helios 2A observation satellite) delayed the attempt. On 11 August 2005, the first Ariane 5GS (featuring the Ariane 5ECA's improved solid motors) boosted Thaicom 4, the heaviest telecommunications satellite to date at , into orbit. On 16 November 2005, the third Ariane 5ECA launch (the second successful ECA launch) took place. It carried a dual payload consisting of Spaceway F2 for DirecTV and Telkom-2 for PT Telekomunikasi of Indonesia. This was the launch vehicle's heaviest dual payload to date, at more than . On 27 May 2006, an Ariane 5ECA launch vehicle set a new commercial payload lifting record of . The dual-payload consisted of the Thaicom 5 and Satmex 6 satellites. On 4 May 2007, the Ariane 5ECA set another new commercial record, lifting into transfer orbit the Astra 1L and Galaxy 17 communication satellites with a combined weight of , and a total payload weight of . This record was again broken by another Ariane 5ECA, launching the Skynet 5B and Star One C1 satellites, on 11 November 2007. The total payload weight for this launch was of . On 9 March 2008, the first Ariane 5ES-ATV was launched to deliver the first ATV called Jules Verne to the International Space Station (ISS). The ATV was the heaviest payload ever launched by a European launch vehicle, providing supplies to the space station with necessary propellant, water, air and dry cargo. This was the first operational Ariane mission which involved an engine restart in the upper stage. The ES-ATV Aestus EPS upper stage was restartable while the ECA HM7-B engine was not. On 1 July 2009, an Ariane 5ECA launched TerreStar-1 (now EchoStar T1), which was then, at , the largest and most massive commercial telecommunication satellite ever built at that time until being overtaken by Telstar 19 Vantage, at , launched aboard Falcon 9. The satellite was launched into a lower-energy orbit than a usual GTO, with its initial apogee at roughly . On 28 October 2010, an Ariane 5ECA launched Eutelsat's W3B (part of its W Series of satellites) and Broadcasting Satellite System Corporation (B-SAT)'s BSAT-3b satellites into orbit. But the W3B satellite failed to operate shortly after the successful launch and was written off as a total loss due to an oxidizer leak in the satellite's main propulsion system. The BSAT-3b satellite, however, is operating normally. The VA253 launch on 15 August 2020 introduced two small changes that increased lift capacity by about ; these were a lighter avionics and guidance-equipment bay, and modified pressure vents on the payload fairing, which were required for the subsequent launch of the James Webb Space Telescope. It also debuted a location system using Galileo navigation satellites. On 25 December 2021, VA256 launched the James Webb Space Telescope towards a Sun–Earth L2 halo orbit. The precision of trajectory following launch led to fuel savings credited with potentially doubling the lifetime of the telescope by leaving more hydrazine propellant on-board for station-keeping than was expected. According to Rudiger Albat, the program manager for Ariane 5, efforts had been made to select components for this flight that had performed especially well during pre-flight testing, including "one of the best Vulcain engines that we've ever built." GTO payload weight records On 22 April 2011, the Ariane 5ECA flight VA-201 broke a commercial record, lifting Yahsat 1A and Intelsat New Dawn with a total payload weight of to transfer orbit. This record was later broken again during the launch of Ariane 5ECA flight VA-208 on 2 August 2012, lifting a total of into the planned geosynchronous transfer orbit, which was broken again 6 months later on flight VA-212 with sent towards geosynchronous transfer orbit. In June 2016, the GTO record was raised to , on the first rocket in history that carried a satellite dedicated to financial institutions. The payload record was pushed a further , up to on 24 August 2016 with the launch of Intelsat 33e and Intelsat 36. On 1 June 2017, the payload record was broken again to carrying ViaSat-2 and Eutelsat-172B. In 2021 VA-255 put 11,210 kg into GTO. VA241 anomaly On 25 January 2018, an Ariane 5ECA launched SES-14 and Al Yah 3 satellites. About 9 minutes and 28 seconds after launch, a telemetry loss occurred between the launch vehicle and the ground controllers. It was later confirmed, about 1 hour and 20 minutes after launch, that both satellites were successfully separated from the upper stage and were in contact with their respective ground controllers, but that their orbital inclinations were incorrect as the guidance systems might have been compromised. Therefore, both satellites conducted orbital procedures, extending commissioning time. SES-14 needed about 8 weeks longer than planned commissioning time, meaning that entry into service was reported early September instead of July. Nevertheless, SES-14 is still expected to be able to meet the designed lifetime. This satellite was originally to be launched with more propellant reserve on a Falcon 9 launch vehicle since the Falcon 9, in this specific case, was intended to deploy this satellite into a high inclination orbit that would require more work from the satellite to reach its final geostationary orbit. The Al Yah 3 was also confirmed healthy after more than 12 hours without further statement, and like SES-14, Al Yah 3's maneuvering plan was also revised to still fulfill the original mission. As of 16 February 2018, Al Yah 3 was approaching the intended geostationary orbit, after series of recovery maneuvers had been performed. The investigation showed that invalid inertial units' azimuth value had sent the vehicle 17° off course but to the intended altitude, they had been programmed for the standard geostationary transfer orbit of 90° when the payloads were intended to be 70° for this supersynchronous transfer orbit mission, 20° off norme. This mission anomaly marked the end of 82nd consecutive success streak since 2003. Launch history Launch statistics Ariane 5 launch vehicles had accumulated 117 launches, 112 of which were successful, yielding a success rate. Between April 2003 and December 2017, Ariane 5 flew 83 consecutive missions without failure, but the launch vehicle suffered a partial failure in January 2018.

Accumulator (computing)

In a computer's central processing unit (CPU), the accumulator is a register in which intermediate arithmetic logic unit results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, perhaps only to be read right back again for use in the next operation. Access to main memory is slower than access to a register like an accumulator because the technology used for the large main memory is slower (but cheaper) than that used for a register. Early electronic computer systems were often split into two groups, those with accumulators and those without. Modern computer systems often have multiple general-purpose registers that can operate as accumulators, and the term is no longer as common as it once was. However, to simplify their design, a number of special-purpose processors still use a single accumulator. Basic concept Mathematical operations often take place in a stepwise fashion, using the results from one operation as the input to the next. For instance, a manual calculation of a worker's weekly payroll might look something like: look up the number of hours worked from the employee's time card look up the pay rate for that employee from a table multiply the hours by the pay rate to get their basic weekly pay multiply their basic pay by a fixed percentage to account for income tax subtract that number from their basic pay to get their weekly pay after tax multiply that result by another fixed percentage to account for retirement plans subtract that number from their basic pay to get their weekly pay after all deductions A computer program carrying out the same task would follow the same basic sequence of operations, although the values being looked up would all be stored in computer memory. In early computers, the number of hours would likely be held on a punch card and the pay rate in some other form of memory, perhaps a magnetic drum. Once the multiplication is complete, the result needs to be placed somewhere. On a "drum machine" this would likely be back to the drum, an operation that takes considerable time. And then the very next operation has to read that value back in, which introduces another considerable delay. Accumulators dramatically improve performance in systems like these by providing a scratchpad area where the results of one operation can be fed to the next one for little or no performance penalty. In the example above, the basic weekly pay would be calculated and placed in the accumulator, which could then immediately be used by the income tax calculation. This removes one save and one read operation from the sequence, operations that generally took tens to hundreds of times as long as the multiplication itself. Accumulator machines An accumulator machine, also called a 1-operand machine, or a CPU with accumulator-based architecture, is a kind of CPU where, although it may have several registers, the CPU mostly stores the results of calculations in one special register, typically called "the accumulator". Almost all computers were accumulator machines with only the high-performance "supercomputers" having multiple registers. Then as mainframe systems gave way to microcomputers, accumulator architectures were again popular with the MOS 6502 being a notable example. Many 8-bit microcontrollers that are still popular as of 2014, such as the PICmicro and 8051, are accumulator-based machines. Modern CPUs are typically 2-operand or 3-operand machines. The additional operands specify which one of many general-purpose registers (also called "general-purpose accumulators") are used as the source and destination for calculations. These CPUs are not considered "accumulator machines". The characteristic which distinguishes one register as being the accumulator of a computer architecture is that the accumulator (if the architecture were to have one) would be used as an implicit operand for arithmetic instructions. For instance, a CPU might have an instruction like: ADD memaddress that adds the value read from memory location memaddress to the value in the accumulator, placing the result back in the accumulator. The accumulator is not identified in the instruction by a register number; it is implicit in the instruction and no other register can be specified in the instruction. Some architectures use a particular register as an accumulator in some instructions, but other instructions use register numbers for explicit operand specification. History of the computer accumulator Any system that uses a single "memory" to store the result of multiple operations can be considered an accumulator. J. Presper Eckert refers to even the earliest adding machines of Gottfried Leibniz and Blaise Pascal as accumulator-based systems. Percy Ludgate was the first to conceive a multiplier-accumulator (MAC) in his Analytical Machine of 1909. Historical convention dedicates a register to "the accumulator", an "arithmetic organ" that literally accumulates its number during a sequence of arithmetic operations: "The first part of our arithmetic organ ... should be a parallel storage organ which can receive a number and add it to the one already in it, which is also able to clear its contents and which can store what it contains. We will call such an organ an Accumulator. It is quite conventional in principle in past and present computing machines of the most varied types, e.g. desk multipliers, standard IBM counters, more modern relay machines, the ENIAC" (Goldstine and von Neumann, 1946; p. 98 in Bell and Newell 1971). Just a few of the instructions are, for example (with some modern interpretation): Clear accumulator and add number from memory location X Clear accumulator and subtract number from memory location X Add number copied from memory location X to the contents of the accumulator Subtract number copied from memory location X from the contents of the accumulator Clear accumulator and shift contents of register into accumulator No convention exists regarding the names for operations from registers to accumulator and from accumulator to registers. Tradition (e.g. Donald Knuth's (1973) hypothetical MIX computer), for example, uses two instructions called load accumulator from register/memory (e.g. "LDA r") and store accumulator to register/memory (e.g. "STA r"). Knuth's model has many other instructions as well. Notable accumulator-based computers The 1945 configuration of ENIAC had 20 accumulators, which could operate in parallel. Each one could store an eight decimal digit number and add to it (or subtract from it) a number it received. Most of IBM's early binary "scientific" computers, beginning with the vacuum tube IBM 701 in 1952, used a single 36-bit accumulator, along with a separate multiplier/quotient register to handle operations with longer results. The IBM 650, a decimal machine, had one 10 digit distributor and two ten-digit accumulators; the IBM 7070, a later, transistorized decimal machine had three accumulators. The IBM System/360, and Digital Equipment Corporation's PDP-6, had 16 general-purpose registers, although the PDP-6 and its successor, the PDP-10, call them accumulators. The 12-bit PDP-8 was one of the first minicomputers to use accumulators, and inspired many later machines. The PDP-8 had but one accumulator. The HP 2100 and Data General Nova had 2 and 4 accumulators. The Nova was created when this follow-on to the PDP-8 was rejected in favor of what would become the PDP-11. The Nova provided four accumulators, AC0-AC3, although AC2 and AC3 could also be used to provide offset addresses, tending towards more generality of usage for the registers. The PDP-11 had 8 general-purpose registers, along the lines of the System/360 and PDP-10; most later CISC and RISC machines provided multiple general-purpose registers. Early 4-bit and 8-bit microprocessors such as the 4004, 8008 and numerous others, typically had single accumulators. The 8051 microcontroller has two, a primary accumulator and a secondary accumulator, where the second is used by instructions only when multiplying (MUL AB) or dividing (DIV AB); the former splits the 16-bit result between the two 8-bit accumulators, whereas the latter stores the quotient on the primary accumulator A and the remainder in the secondary accumulator B. As a direct descendant of the 8008, the 8080, and the 8086, the modern ubiquitous Intel x86 processors still uses the primary accumulator EAX and the secondary accumulator EDX for multiplication and division of large numbers. For instance, MUL ECX will multiply the 32-bit registers ECX and EAX and split the 64-bit result between EAX and EDX. However, MUL and DIV are special cases; other arithmetic-logical instructions (ADD, SUB, CMP, AND, OR, XOR, TEST) may specify any of the eight registers EAX, ECX, EDX, EBX, ESP, EBP, ESI, EDI as the accumulator (i.e. left operand and destination). This is also supported for multiply if the upper half of the result is not required. x86 is thus a fairly general register architecture, despite being based on an accumulator model. The 64-bit extension of x86, x86-64, has been further generalized to 16 instead of 8 general registers.

Arithmetic

Arithmetic () is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today. History The prehistory of arithmetic is limited to a small number of artifacts that may indicate the conception of addition and subtraction; the best-known is the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed. The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations: addition, subtraction, multiplication, and division, as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, but the characteristics of the particular numeral system strongly influence the complexity of the methods. The hieroglyphic system for Egyptian numerals, like the later Roman numerals, descended from tally marks used for counting. In both cases, this origin resulted in values that used a decimal base but did not include positional notation. Complex calculations with Roman numerals required the assistance of a counting board (or the Roman abacus) to obtain the results. Early number systems that included positional notation were not decimal; these include the sexagesimal (base 60) system for Babylonian numerals and the vigesimal (base 20) system that defined Maya numerals. Because of the place-value concept, the ability to reuse the same digits for different values contributed to simpler and more efficient methods of calculation. The continuous historical development of modern arithmetic starts with the Hellenistic period of ancient Greece; it originated much later than the Babylonian and Egyptian examples. Prior to the works of Euclid around 300 BC, Greek studies in mathematics overlapped with philosophical and mystical beliefs. Nicomachus is an example of this viewpoint, using the earlier Pythagorean approach to numbers and their relationships to each other in his work, Introduction to Arithmetic. Greek numerals were used by Archimedes, Diophantus, and others in a positional notation not very different from modern notation. The ancient Greeks lacked a symbol for zero until the Hellenistic period, and they used three separate sets of symbols as digits: one set for the units place, one for the tens place, and one for the hundreds. For the thousands place, they would reuse the symbols for the units place, and so on. Their addition algorithm was identical to the modern method, and their multiplication algorithm was only slightly different. Their long division algorithm was the same, and the digit-by-digit square root algorithm, popularly used as recently as the 20th century, was known to Archimedes (who may have invented it). He preferred it to Hero's method of successive approximation because, once computed, a digit does not change, and the square roots of perfect squares, such as 7485696, terminate immediately as 2736. For numbers with a fractional part, such as 546.934, they used negative powers of 60 instead of negative powers of 10 for the fractional part 0.934. The ancient Chinese had advanced arithmetic studies dating from the Shang Dynasty and continuing through the Tang Dynasty, from basic numbers to advanced algebra. The ancient Chinese used a positional notation similar to that of the Greeks. Since they also lacked a symbol for zero, they had one set of symbols for the units place and a second set for the tens place. For the hundreds place, they then reused the symbols for the units place, and so on. Their symbols were based on ancient counting rods. The exact time when the Chinese started calculating with positional representation is unknown, though it is known that the adoption started before 400 BC. The ancient Chinese were the first to meaningfully discover, understand, and apply negative numbers. This is explained in the Nine Chapters on the Mathematical Art (Jiuzhang Suanshu), which was written by Liu Hui and dates back to the 2nd century BC. The gradual development of the Hindu–Arabic numeral system independently devised the place-value concept and positional notation, which combined the simpler methods for computations with a decimal base and the use of a digit representing 0. This allowed the system to consistently represent both large and small integers—an approach that eventually replaced all other systems. In the early the Indian mathematician Aryabhata incorporated an existing version of this system into his work and experimented with different notations. In the 7th century, Brahmagupta established the use of 0 as a separate number and determined the results for multiplication, division, addition, and subtraction of zero and all other numbers—except for the result of division by zero. His contemporary, the Syriac bishop Severus Sebokht (650 AD) said, "Indians possess a method of calculation that no word can praise enough. Their rational system of mathematics, or of their method of calculation. I mean the system using nine symbols." The Arabs also learned this new method and called it hesab. Although the Codex Vigilanus described an early form of Arabic numerals (omitting 0) by 976 AD, Leonardo of Pisa (Fibonacci) was primarily responsible for spreading their use throughout Europe after the publication of his book in 1202. He wrote, "The method of the Indians (Latin Modus Indorum) surpasses any known method to compute. It's a marvelous method. They do their computations using nine figures and symbol zero". In the Middle Ages, arithmetic was one of the seven liberal arts taught in universities. The flourishing of algebra in the medieval Islamic world, and also in Renaissance Europe, was an outgrowth of the enormous simplification of computation through decimal notation. Various types of tools have been invented and widely used to assist in numeric calculations. Before Renaissance, they were various types of abaci. More recent examples include slide rules, nomograms and mechanical calculators, such as Pascal's calculator. At present, they have been supplanted by electronic calculators and computers. Arithmetic operations The basic arithmetic operations are addition, subtraction, multiplication and division, although arithmetic also includes more advanced operations, such as manipulations of percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, in the same vein as logarithms (prosthaphaeresis). Arithmetic expressions must be evaluated according to the intended sequence of operations. There are several methods to specify this, either—most common, together with infix notation—explicitly using parentheses and relying on precedence rules, or using a prefix or postfix notation, which uniquely fix the order of execution by themselves. Any set of objects upon which all four arithmetic operations (except division by zero) can be performed, and where these four operations obey the usual laws (including distributivity), is called a field. Addition Addition, denoted by the symbol , is the most basic operation of arithmetic. In its simple form, addition combines two numbers, the addends or terms, into a single number, the sum of the numbers (such as or ). Adding finitely many numbers can be viewed as repeated simple addition; this procedure is known as summation, a term also used to denote the definition for "adding infinitely many numbers" in an infinite series. Repeated addition of the number 1 is the most basic form of counting; the result of adding is usually called the successor of the original number. Addition is commutative and associative, so the order in which finitely many terms are added does not matter. The number has the property that, when added to any number, it yields that same number; so, it is the identity element of addition, or the additive identity. For every number , there is a number denoted , called the opposite of , such that and . So, the opposite of is the inverse of with respect to addition, or the additive inverse of . For example, the opposite of is , since . Addition can also be interpreted geometrically, as in the following example. If we have two sticks of lengths 2 and 5, then, if the sticks are aligned one after the other, the length of the combined stick becomes 7, since . Subtraction Subtraction, denoted by the symbol , is the inverse operation to addition. Subtraction finds the difference between two numbers, the minuend minus the subtrahend: Resorting to the previously established addition, this is to say that the difference is the number that, when added to the subtrahend, results in the minuend: For positive arguments and holds: If the minuend is larger than the subtrahend, the difference is positive. If the minuend is smaller than the subtrahend, the difference is negative. In any case, if minuend and subtrahend are equal, the difference Subtraction is neither commutative nor associative. For that reason, the construction of this inverse operation in modern algebra is often discarded in favor of introducing the concept of inverse elements (as sketched under ), where subtraction is regarded as adding the additive inverse of the subtrahend to the minuend, that is, . The immediate price of discarding the binary operation of subtraction is the introduction of the (trivial) unary operation, delivering the additive inverse for any given number, and losing the immediate access to the notion of difference, which is potentially misleading when negative arguments are involved. For any representation of numbers, there are methods for calculating results, some of which are particularly advantageous in exploiting procedures, existing for one operation, by small alterations also for others. For example, digital computers can reuse existing adding-circuitry and save additional circuits for implementing a subtraction, by employing the method of two's complement for representing the additive inverses, which is extremely easy to implement in hardware (negation). The trade-off is the halving of the number range for a fixed word length. A formerly widespread method to achieve a correct change amount, knowing the due and given amounts, is the counting up method, which does not explicitly generate the value of the difference. Suppose an amount P is given in order to pay the required amount Q, with P greater than Q. Rather than explicitly performing the subtraction P − Q = C and counting out that amount C in change, money is counted out starting with the successor of Q, and continuing in the steps of the currency, until P is reached. Although the amount counted out must equal the result of the subtraction P − Q, the subtraction was never really done and the value of P − Q is not supplied by this method. Multiplication Multiplication, denoted by the symbols or , is the second basic operation of arithmetic. Multiplication also combines two numbers into a single number, the product. The two original numbers are called the multiplier and the multiplicand, mostly both are called factors. Multiplication may be viewed as a scaling operation. If the numbers are imagined as lying in a line, multiplication by a number greater than 1, say x, is the same as stretching everything away from 0 uniformly, in such a way that the number 1 itself is stretched to where x was. Similarly, multiplying by a number less than 1 can be imagined as squeezing towards 0, in such a way that 1 goes to the multiplicand. Another view on multiplication of integer numbers (extendable to rationals but not very accessible for real numbers) is by considering it as repeated addition. For example. corresponds to either adding times a , or times a , giving the same result. There are different opinions on the advantageousness of these paradigmata in math education. Multiplication is commutative and associative; further, it is distributive over addition and subtraction. The multiplicative identity is 1, since multiplying any number by 1 yields that same number. The multiplicative inverse for any number except  is the reciprocal of this number, because multiplying the reciprocal of any number by the number itself yields the multiplicative identity .  is the only number without a multiplicative inverse, and the result of multiplying any number and is again One says that is not contained in the multiplicative group of the numbers. The product of a and b is written as or . It can also written by simple juxtaposition: ab. In computer programming languages and software packages (in which one can only use characters normally found on a keyboard), it is often written with an asterisk: a * b. Algorithms implementing the operation of multiplication for various representations of numbers are by far more costly and laborious than those for addition. Those accessible for manual computation either rely on breaking down the factors to single place values and applying repeated addition, or on employing tables or slide rules, thereby mapping multiplication to addition and vice versa. These methods are outdated and are gradually replaced by mobile devices. Computers use diverse sophisticated and highly optimized algorithms, to implement multiplication and division for the various number formats supported in their system. Division Division, denoted by the symbols or , is essentially the inverse operation to multiplication. Division finds the quotient of two numbers, the dividend divided by the divisor. Under common rules, dividend divided by zero is undefined. For distinct positive numbers, if the dividend is larger than the divisor, the quotient is greater than 1, otherwise it is less than or equal to 1 (a similar rule applies for negative numbers). The quotient multiplied by the divisor always yields the dividend. Division is neither commutative nor associative. So as explained in , the construction of the division in modern algebra is discarded in favor of constructing the inverse elements with respect to multiplication, as introduced in . Hence division is the multiplication of the dividend with the reciprocal of the divisor as factors, that is, Within the natural numbers, there is also a different but related notion called Euclidean division, which outputs two numbers after "dividing" a natural (numerator) by a natural (denominator): first a natural (quotient), and second a natural (remainder) such that and In some contexts, including computer programming and advanced arithmetic, division is extended with another output for the remainder. This is often treated as a separate operation, the Modulo operation, denoted by the symbol or the word , though sometimes a second output for one "divmod" operation. In either case, Modular arithmetic has a variety of use cases. Different implementations of division (floored, truncated, Euclidean, etc.) correspond with different implementations of modulus. Fundamental theorem of arithmetic The fundamental theorem of arithmetic states that any integer greater than 1 has a unique prime factorization (a representation of a number as the product of prime factors), excluding the order of the factors. For example, 252 only has one prime factorization: 252 = 2 × 3 × 7 Euclid's Elements first introduced this theorem, and gave a partial proof (which is called Euclid's lemma). The fundamental theorem of arithmetic was first proven by Carl Friedrich Gauss. The fundamental theorem of arithmetic is one of the reasons why 1 is not considered a prime number. Other reasons include the sieve of Eratosthenes, and the definition of a prime number itself (a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.). Decimal arithmetic refers exclusively, in common use, to the written numeral system employing arabic numerals as the digits for a radix 10 ("decimal") positional notation; however, any numeral system based on powers of 10, e.g., Greek, Cyrillic, Roman, or Chinese numerals may conceptually be described as "decimal notation" or "decimal representation". Modern methods for four fundamental operations (addition, subtraction, multiplication and division) were first devised by Brahmagupta of India. This was known during medieval Europe as "Modus Indorum" or Method of the Indians. Positional notation (also known as "place-value notation") refers to the representation or encoding of numbers using the same symbol for the different orders of magnitude (e.g., the "ones place", "tens place", "hundreds place") and, with a radix point, using those same symbols to represent fractions (e.g., the "tenths place", "hundredths place"). For example, 507.36 denotes 5 hundreds (102), plus 0 tens (101), plus 7 units (100), plus 3 tenths (10−1) plus 6 hundredths (10−2). The concept of 0 as a number comparable to the other basic digits is essential to this notation, as is the concept of 0's use as a placeholder, and as is the definition of multiplication and addition with 0. The use of 0 as a placeholder and, therefore, the use of a positional notation is first attested to in the Jain text from India entitled the Lokavibhâga, dated 458 AD and it was only in the early 13th century that these concepts, transmitted via the scholarship of the Arabic world, were introduced into Europe by Fibonacci using the Hindu–Arabic numeral system. Algorism comprises all of the rules for performing arithmetic computations using this type of written numeral. For example, addition produces the sum of two arbitrary numbers. The result is calculated by the repeated addition of single digits from each number that occupies the same position, proceeding from right to left. An addition table with ten rows and ten columns displays all possible values for each sum. If an individual sum exceeds the value 9, the result is represented with two digits. The rightmost digit is the value for the current position, and the result for the subsequent addition of the digits to the left increases by the value of the second (leftmost) digit, which is always one (if not zero). This adjustment is termed a carry of the value 1. The process for multiplying two arbitrary numbers is similar to the process for addition. A multiplication table with ten rows and ten columns lists the results for each pair of digits. If an individual product of a pair of digits exceeds 9, the carry adjustment increases the result of any subsequent multiplication from digits to the left by a value equal to the second (leftmost) digit, which is any value from (). Additional steps define the final result. Similar techniques exist for subtraction and division. The creation of a correct process for multiplication relies on the relationship between values of adjacent digits. The value for any single digit in a numeral depends on its position. Also, each position to the left represents a value ten times larger than the position to the right. In mathematical terms, the exponent for the radix (base) of 10 increases by 1 (to the left) or decreases by 1 (to the right). Therefore, the value for any arbitrary digit is multiplied by a value of the form 10n with integer n. The list of values corresponding to all possible positions for a single digit is written Repeated multiplication of any value in this list by 10 produces another value in the list. In mathematical terminology, this characteristic is defined as closure, and the previous list is described as . It is the basis for correctly finding the results of multiplication using the previous technique. This outcome is one example of the uses of number theory. Compound unit arithmetic Compound unit arithmetic is the application of arithmetic operations to mixed radix quantities such as feet and inches; gallons and pints; pounds, shillings and pence; and so on. Before decimal-based systems of money and units of measure, compound unit arithmetic was widely used in commerce and industry. Basic arithmetic operations The techniques used in compound unit arithmetic were developed over many centuries and are well documented in many textbooks in many different languages. In addition to the basic arithmetic functions encountered in decimal arithmetic, compound unit arithmetic employs three more functions: , in which a compound quantity is reduced to a single quantity—for example, conversion of a distance expressed in yards, feet and inches to one expressed in inches. , the inverse function to reduction, is the conversion of a quantity that is expressed as a single unit of measure to a compound unit, such as expanding 24 oz to . is the conversion of a set of compound units to a standard form—for example, rewriting "" as "". Knowledge of the relationship between the various units of measure, their multiples and their submultiples forms an essential part of compound unit arithmetic. Principles of compound unit arithmetic There are two basic approaches to compound unit arithmetic: where all the compound unit variables are reduced to single unit variables, the calculation performed and the result expanded back to compound units. This approach is suited for automated calculations. A typical example is the handling of time by Microsoft Excel where all time intervals are processed internally as days and decimal fractions of a day. in which each unit is treated separately and the problem is continuously normalized as the solution develops. This approach, which is widely described in classical texts, is best suited for manual calculations. An example of the ongoing normalization method as applied to addition is shown below. The addition operation is carried out from right to left; in this case, pence are processed first, then shillings followed by pounds. The numbers below the "answer line" are intermediate results. The total in the pence column is 25. Since there are 12 pennies in a shilling, 25 is divided by 12 to give 2 with a remainder of 1. The value "1" is then written to the answer row and the value "2" carried forward to the shillings column. This operation is repeated using the values in the shillings column, with the additional step of adding the value that was carried forward from the pennies column. The intermediate total is divided by 20 as there are 20 shillings in a pound. The pound column is then processed, but as pounds are the largest unit that is being considered, no values are carried forward from the pounds column. For the sake of simplicity, the example chosen did not have farthings. Operations in practice During the 19th and 20th centuries various aids were developed to aid the manipulation of compound units, particularly in commercial applications. The most common aids were mechanical tills which were adapted in countries such as the United Kingdom to accommodate pounds, shillings, pence and farthings, and ready reckoners, which are books aimed at traders that catalogued the results of various routine calculations such as the percentages or multiples of various sums of money. One typical booklet that ran to 150 pages tabulated multiples "from one to ten thousand at the various prices from one farthing to one pound". The cumbersome nature of compound unit arithmetic has been recognized for many years—in 1586, the Flemish mathematician Simon Stevin published a small pamphlet called De Thiende ("the tenth") in which he declared the universal introduction of decimal coinage, measures, and weights to be merely a question of time. In the modern era, many conversion programs, such as that included in the Microsoft Windows 7 operating system calculator, display compound units in a reduced decimal format rather than using an expanded format (e.g., "2.5 ft" is displayed rather than ). Number theory Until the 19th century, number theory was a synonym of "arithmetic". The addressed problems were directly related to the basic operations and concerned primality, divisibility, and the solution of equations in integers, such as Fermat's Last Theorem. It appeared that most of these problems, although very elementary to state, are very difficult and may not be solved without very deep mathematics involving concepts and methods from many other branches of mathematics. This led to new branches of number theory such as analytic number theory, algebraic number theory, Diophantine geometry and arithmetic algebraic geometry. Wiles' proof of Fermat's Last Theorem is a typical example of the necessity of sophisticated methods, which go far beyond the classical methods of arithmetic, for solving problems that can be stated in elementary arithmetic. Arithmetic in education Primary education in mathematics often places a strong focus on algorithms for the arithmetic of natural numbers, integers, fractions, and decimals (using the decimal place-value system). This study is sometimes known as algorism. The difficulty and unmotivated appearance of these algorithms has long led educators to question this curriculum, advocating the early teaching of more central and intuitive mathematical ideas. One notable movement in this direction was the New Math of the 1960s and 1970s, which attempted to teach arithmetic in the spirit of axiomatic development from set theory, an echo of the prevailing trend in higher mathematics. Also, arithmetic was used by Islamic Scholars in order to teach application of the rulings related to Zakat and Irth. This was done in a book entitled The Best of Arithmetic by Abd-al-Fattah-al-Dumyati. The book begins with the foundations of mathematics and proceeds to its application in the later chapters.

Advanced Power Management

Advanced power management (APM) is a technical standard for power management developed by Intel and Microsoft and released in 1992 which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management. Revision 1.2 was the last version of the APM specification, released in 1996. ACPI is the successor to APM. Microsoft dropped support for APM in Windows Vista. The Linux kernel still mostly supports APM, though support for APM CPU idle was dropped in version 3.0. Overview APM uses a layered approach to manage devices. APM-aware applications (which include device drivers) talk to an OS-specific APM driver. This driver communicates to the APM-aware BIOS, which controls the hardware. There is the ability to opt out of APM control on a device-by-device basis, which can be used if a driver wants to communicate directly with a hardware device. Communication occurs both ways; power management events are sent from the BIOS to the APM driver, and the APM driver sends information and requests to the BIOS via function calls. In this way the APM driver is an intermediary between the BIOS and the operating system. Power management happens in two ways; through the above-mentioned function calls from the APM driver to the BIOS requesting power state changes, and automatically based on device activity. In APM 1.0 and APM 1.1, power management is almost fully controlled by the BIOS. In APM 1.2, the operating system can control PM time (e.g. suspend timeout). Power management events There are 12 power events (such as standby, suspend and resume requests, and low battery notifications), plus OEM-defined events, that can be sent from the APM BIOS to the operating system. The APM driver regularly polls for event change notifications. Power Management Events: APM functions There are 21 APM function calls defined that the APM driver can use to query power management statuses, or request power state transitions. Example function calls include letting the BIOS know about current CPU usage (the BIOS may respond to such a call by placing the CPU in a low-power state, or returning it to its full-power state), retrieving the current power state of a device, or requesting a power state change. Power states The APM specification defines system power states and device power states. System power states APM defines five power states for the computer system: Full On: The computer is powered on, and no devices are in a power saving mode. APM Enabled: The computer is powered on, and APM is controlling device power management as needed. APM Standby: Most devices are in their low-power state, the CPU is slowed or stopped, and the system state is saved. The computer can be returned to its former state quickly (in response to activity such as the user pressing a key on the keyboard). APM Suspend: Most devices are powered off, but the system state is saved. The computer can be returned to its former state, but takes a relatively long time. (Hibernation is a special form of the APM Suspend state). Off: The computer is turned off. Device power states APM also defines power states that APM-aware hardware can implement. There is no requirement that an APM-aware device implement all states. The four states are: Device On: The device is in full power mode. Device Power Managed: The device is still powered on, but some functions may not be available, or may have reduced performance. Device Low Power: The device is not working. Power is maintained so that the device may be 'woken up'. Device Off: The device is powered off. Hardware components CPU The CPU core (defined in APM as the CPU clock, cache, system bus and system timers) is treated specially in APM, as it is the last device to be powered down, and the first device to be powered back up. The CPU core is always controlled through the APM BIOS (there is no option to control it through a driver). Drivers can use APM function calls to notify the BIOS about CPU usage, but it is up to the BIOS to act on this information; a driver cannot directly tell the CPU to go into a power saving state. ATA drives The ATA specification and SATA specification defines APM provisions for hard drives, which specifies a trade-off between spin-down frequency and always-on performance. Unlike the BIOS-side APM, the ATA APM and SATA APM has never been deprecated. Aggressive spin-down frequencies may reduce drive lifespan by unnecessarily accumulating load cycles; most modern drives are specified to sustain 300,000 cycles and usually last at least 600,000. On the other hand, not spinning down the drive will cause extra power draw and heat generation; high temperatures also reduce the lifespan of hard drives.

Atlanta

Atlanta ( , or ) is the capital and most populous city of the U.S. state of Georgia. It is the seat of Fulton County, although a portion of the city extends into neighboring DeKalb County. With a population of 498,715 living within the city limits, Atlanta is the eighth most populous city in the Southeast and 38th most populous city in the United States according to the 2020 U.S. census. It is the core of the much larger Atlanta metropolitan area, which is home to more than 6.2 million people (2022 estimate), making it the eighth-largest U.S. metropolitan area. Situated among the foothills of the Appalachian Mountains at an elevation of just over above sea level, Atlanta features unique topography that includes rolling hills, lush greenery, and the densest urban tree coverage of any major city in the United States. Atlanta was originally founded as the terminus of a major state-sponsored railroad, but it soon became the convergence point among several railroads, spurring its rapid growth. The largest was the Western and Atlantic Railroad, from which the name "Atlanta" is derived, signifying the city's growing reputation as a major hub of transportation. During the American Civil War, it served a strategically important role for the Confederacy until it was captured in 1864. The city was almost entirely burned to the ground during General William T. Sherman's March to the Sea. However, the city rebounded dramatically in the post-war period and quickly became a national industrial center and the unofficial capital of the "New South". After World War II, it also became a manufacturing and technology hub. During the 1950s and 1960s, it became a major organizing center of the American Civil Rights Movement, with Martin Luther King Jr., Ralph David Abernathy, and many other locals becoming prominent figures in the movement's leadership. In the modern era, Atlanta has remained a major center of transportation, with Hartsfield-Jackson International Airport becoming the world's busiest airport by passenger traffic in 1998 (a position it has held every year since, except for 2020), with an estimated 93.7 million passengers in 2022. With a nominal gross domestic product (GDP) of $473 billion in 2021, Atlanta has the eleventh largest economy of cities in the U.S. and the 22nd largest in the world. Its economy is considered diverse, with dominant sectors in industries including transportation, aerospace, logistics, healthcare, news and media operations, film and television production, information technology, finance, and biomedical research and public policy. The gentrification of some of its neighborhoods, initially spurred by the 1996 Summer Olympics, has intensified in the 21st century with the growth of the Atlanta Beltline. This has altered its demographics, politics, aesthetics, and culture. History Native American settlements For thousands of years prior to the arrival of European settlers in North Georgia, the indigenous Creek people and their ancestors inhabited the area. Standing Peachtree, a Creek village where Peachtree Creek flows into the Chattahoochee River, was the closest Native American settlement to what is now Atlanta. Through the early 19th century, European Americans systematically encroached on the Creek of northern Georgia, forcing them out of the area from 1802 to 1825. The Creek were forced to leave the area in 1821, under Indian Removal by the federal government, and European American settlers arrived the following year. Western and Atlantic Railroad In 1836, the Georgia General Assembly voted to build the Western and Atlantic Railroad in order to provide a link between the port of Savannah and the Midwest. The initial route was to run southward from Chattanooga to a terminus east of the Chattahoochee River, which would be linked to Savannah. After engineers surveyed various possible locations for the terminus, the "zero milepost" was driven into the ground in what is now Foundry Street, Five Points. When asked in 1837 about the future of the little village, Stephen Harriman Long, the railroad's chief engineer said the place would be good "for one tavern, a blacksmith shop, a grocery store, and nothing else". A year later, the area around the milepost had developed into a settlement, first known as Terminus, and later Thrasherville, after a local merchant who built homes and a general store in the area. By 1842, the town had six buildings and 30 residents and was renamed Marthasville to honor Governor Wilson Lumpkin's daughter Martha. Later, John Edgar Thomson, Chief Engineer of the Georgia Railroad, suggested the town be renamed Atlanta. The residents approved, and the town was incorporated as Atlanta on December 29, 1847. Civil War By 1860, Atlanta's population had grown to 9,554. During the American Civil War, the nexus of multiple railroads in Atlanta made the city a strategic hub for the distribution of military supplies. In 1864, the Union Army moved southward following the capture of Chattanooga and began its invasion of north Georgia. The region surrounding Atlanta was the location of several major army battles, culminating with the Battle of Atlanta and a four-month-long siege of the city by the Union Army under the command of General William Tecumseh Sherman. On September 1, 1864, Confederate General John Bell Hood decided to retreat from Atlanta, and he ordered the destruction of all public buildings and possible assets that could be of use to the Union Army. On the next day, Mayor James Calhoun surrendered Atlanta to the Union Army, and on September 7, Sherman ordered the city's civilian population to evacuate. On November 11, 1864, Sherman prepared for the Union Army's March to the Sea by ordering the destruction of Atlanta's remaining military assets. Reconstruction and late 19th century After the Civil War ended in 1865, Atlanta was gradually rebuilt during the Reconstruction era. The work attracted many new residents. Due to the city's superior rail transportation network, the state capital was moved from Milledgeville to Atlanta in 1868. In the 1880 Census, Atlanta had surpassed Savannah as Georgia's largest city. Beginning in the 1880s, Henry W. Grady, the editor of the Atlanta Constitution newspaper, promoted Atlanta to potential investors as a city of the "New South" that would be based upon a modern economy and less reliant on agriculture. By 1885, the founding of the Georgia School of Technology (now Georgia Tech) and the Atlanta University Center, a consortium of historically Black colleges made up of units for men and women, had established Atlanta as a center for higher education. In 1895, Atlanta hosted the Cotton States and International Exposition, which attracted nearly 800,000 attendees and successfully promoted the New South's development to the world. 20th century During the first decades of the 20th century, Atlanta enjoyed a period of unprecedented growth. In three decades' time, Atlanta's population tripled as the city limits expanded to include nearby streetcar suburbs. The city's skyline grew taller with the construction of the Equitable, Flatiron, Empire, and Candler buildings. Sweet Auburn emerged as a center of Black commerce. The period was also marked by strife and tragedy. Increased racial tensions led to the Atlanta Race Riot of 1906, when Whites attacked Blacks, leaving at least 27 people dead and over 70 injured, with extensive damage in Black neighborhoods. In 1913, Leo Frank, a Jewish-American factory superintendent, was convicted of the murder of a 13-year-old girl in a highly publicized trial. He was sentenced to death but the governor commuted his sentence to life. An enraged and organized lynch mob took him from jail in 1915 and hanged him in Marietta. The Jewish community in Atlanta and across the country were horrified. On May 21, 1917, the Great Atlanta Fire destroyed 1,938 buildings in what is now the Old Fourth Ward, resulting in one fatality and the displacement of 10,000 people. On December 15, 1939, Atlanta hosted the premiere of Gone with the Wind, the epic film based on the best-selling novel by Atlanta's Margaret Mitchell. The gala event at Loew's Grand Theatre was attended by the film's legendary producer, David O. Selznick, and the film's stars Clark Gable, Vivien Leigh, and Olivia de Havilland, but Oscar winner Hattie McDaniel, an African-American actress, was barred from the event due to racial segregation laws. Metropolitan area's growth Atlanta played a vital role in the Allied effort during World War II due to the city's war-related manufacturing companies, railroad network and military bases. The defense industries attracted thousands of new residents and generated revenues, resulting in rapid population and economic growth. In the 1950s, the city's newly constructed highway system, supported by federal subsidies, allowed middle class Atlantans the ability to relocate to the suburbs. As a result, the city began to make up an ever-smaller proportion of the metropolitan area's population. Georgia Tech's president Blake R. Van Leer played an important role with a goal of making Atlanta the home of the "MIT of the South." In 1946 Georgia Tech secured about $240,000 () annually in sponsored research and purchased an electron microscope for $13,000 (), the first such instrument in the Southeastern United States and one of few in the United States at the time. The Research Building was expanded, and a $300,000 () Westinghouse A-C network calculator was given to Georgia Tech by Georgia Power in 1947. In 1953, Van Leer assisted with helping Lockheed establish a research and development and production line in Marietta. Later in 1955 he helped set up a committee to assist with establishing a nuclear research facility, which would later become the Neely Nuclear Research Center. Van Leer also co-founded Southern Polytechnic State University now absorbed by and made part of Kennesaw State University to help meet the need for technicians after the war. Van Leer was instrumental in making the school and Atlanta the first major research center in the American South. The building that houses Tech's school of Electrical and Computer Engineering bears his name. Civil Rights movement African-American veterans returned from World War II seeking full rights in their country and began heightened activism. In exchange for support by that portion of the Black community that could vote, in 1948 the mayor ordered the hiring of the first eight African-American police officers in the city. Much controversy preceded the 1956 Sugar Bowl, when the Pitt Panthers, with African-American fullback Bobby Grier on the roster, met the Georgia Tech Yellow Jackets. There had been controversy over whether Grier should be allowed to play due to his race, and whether Georgia Tech should even play at all due to Georgia's Governor Marvin Griffin's opposition to racial integration. After Griffin publicly sent a telegram to the state's Board of Regents requesting Georgia Tech not to engage in racially integrated events, Georgia Tech's president Blake R. Van Leer rejected the request and threatened to resign. The game went on as planned. In the 1960s, Atlanta became a major organizing center of the civil rights movement, with Martin Luther King Jr., Ralph David Abernathy, and students from Atlanta's historically Black colleges and universities playing major roles in the movement's leadership. While Atlanta in the postwar years had relatively minimal racial strife compared to other cities, Blacks were limited by discrimination, segregation, and continued disenfranchisement of most voters. In 1961, the city attempted to thwart blockbusting by realtors by erecting road barriers in Cascade Heights, countering the efforts of civic and business leaders to foster Atlanta as the "city too busy to hate." Desegregation of the public sphere came in stages, with public transportation desegregated by 1959, the restaurant at Rich's department store by 1961, movie theaters by 1963, and public schools by 1973 (nearly 20 years after the US Supreme Court ruled that segregated public schools were unconstitutional). In 1960, Whites comprised 61.7% of the city's population. During the 1950s–70s, suburbanization and White flight from urban areas led to a significant demographic shift. By 1970, African Americans were the majority of the city's population and exercised their recently enforced voting rights and political influence by electing Atlanta's first Black mayor, Maynard Jackson, in 1973. Under Mayor Jackson's tenure, Atlanta's airport was modernized, strengthening the city's role as a transportation center. The opening of the Georgia World Congress Center in 1976 heralded Atlanta's rise as a convention city. Construction of the city's subway system began in 1975, with rail service commencing in 1979. Despite these improvements, Atlanta lost more than 100,000 residents between 1970 and 1990, over 20% of its population. At the same time, it developed new office space after attracting numerous corporations, with an increasing portion of workers from northern areas. 1996 Summer Olympic games Atlanta was selected as the site for the 1996 Summer Olympic Games. Following the announcement, the city government undertook several major construction projects to improve Atlanta's parks, sporting venues, and transportation infrastructure; however, for the first time, none of the $1.7 billion cost of the games was governmentally funded. While the games experienced transportation and accommodation problems and, despite extra security precautions, there was the Centennial Olympic Park bombing, the spectacle was a watershed event in Atlanta's history. For the first time in Olympic history, every one of the record 197 national Olympic committees invited to compete sent athletes, sending more than 10,000 contestants participating in a record 271 events. The related projects such as Atlanta's Olympic Legacy Program and civic effort initiated a fundamental transformation of the city in the following decade. Since the 21st century During the 2000s, the city of Atlanta underwent a profound physical, cultural, and demographic change. As some of the African American middle and upper classes also began to move to the suburbs, a booming economy drew numerous new migrants from other cities in the United States, who contributed to changes in the city's demographics. African Americans made up a decreasing portion of the population, from a high of 67% in 1990 to 54% in 2010. From 2000 to 2010, Atlanta gained 22,763 white residents, 5,142 Asian residents, and 3,095 Hispanic residents, while the city's Black population decreased by 31,678. Much of the city's demographic change during the decade was driven by young, college-educated professionals: from 2000 to 2009, the three-mile radius surrounding Downtown Atlanta gained 9,722 residents aged 25 to 34 and holding at least a four-year degree, an increase of 61%. This was similar to the tendency in other cities for young, college educated, single or married couples to live in downtown areas. Between the mid-1990s and 2010, stimulated by funding from the HOPE VI program and under leadership of CEO Renee Lewis Glover (1994–2013), the Atlanta Housing Authority demolished nearly all of its public housing, a total of 17,000 units and about 10% of all housing units in the city. After reserving 2,000 units mostly for elderly, the AHA allowed redevelopment of the sites for mixed-use and mixed-income, higher density developments, with 40% of the units to be reserved for affordable housing. Two-fifths of previous public housing residents attained new housing in such units; the remainder received vouchers to be used at other units, including in suburbs. At the same time, in an effort to change the culture of those receiving subsidized housing, the AHA imposed a requirement for such residents to work (or be enrolled in a genuine, limited-time training program). It is virtually the only housing authority to have created this requirement. To prevent problems, the AHA also gave authority to management of the mixed-income or voucher units to evict tenants who did not comply with the work requirement or who caused behavior problems. In 2005, the city approved the $2.8 billion BeltLine project. It was intended to convert a disused 22-mile freight railroad loop that surrounds the central city into an art-filled multi-use trail and light rail transit line, which would increase the city's park space by 40%. The project stimulated retail and residential development along the loop, but has been criticized for its adverse effects on some Black communities. In 2013, the project received a federal grant of $18 million to develop the southwest corridor. In September 2019 the James M. Cox Foundation gave $6 Million to the PATH Foundation which will connect the Silver Comet Trail to The Atlanta BeltLine which is expected to be completed by 2022. Upon completion, the total combined interconnected trail distance around Atlanta for The Atlanta BeltLine and Silver Comet Trail will be the longest paved trail surface in the U.S. totaling about . Atlanta's cultural offerings expanded during the 2000s: the High Museum of Art doubled in size; the Alliance Theatre won a Tony Award; and art galleries were established on the once-industrial Westside. The College Football Hall of Fame relocated to Atlanta and the National Center for Civil and Human Rights museum was constructed. The city of Atlanta was the subject of a massive cyberattack which began in March 2018. In December 2019, Atlanta hosted the Miss Universe 2019 pageant competition. On June 16, 2022, Atlanta was selected as a host city for the 2026 FIFA World Cup. Geography Atlanta encompasses , of which is land and is water. The city is situated in the Deep South of the southeastern United States among the foothills of the Appalachian Mountains. At above mean sea level, Atlanta has the highest elevation among major cities east of the Mississippi River. Atlanta straddles the Eastern Continental Divide. Rainwater that falls on the south and east side of the divide flows into the Atlantic Ocean, while rainwater on the north and west side of the divide flows into the Gulf of Mexico. Atlanta developed on a ridge south of the Chattahoochee River, which is part of the ACF River Basin. The river borders the far northwestern edge of the city, and much of its natural habitat has been preserved, in part by the Chattahoochee River National Recreation Area. Atlanta is 21 miles (33 km) southeast of Marietta, 27 miles (43 km) southwest of Alpharetta, 146 miles (234 km) southwest of Greenville, South Carolina, 147 miles (236 km) east of Birmingham, Alabama, and 245 miles (394 km) southwest of Charlotte, North Carolina. Atlanta is sometimes called "City of Trees" or "city in a forest", despite having lost approximately of trees between 1973 and 1999. Cityscape Most of Atlanta was burned during the American Civil War, depleting the city of a large stock of its historic architecture. Yet architecturally, the city had never been traditionally "southern" because Atlanta originated as a railroad town, rather than a southern seaport dominated by the planter class, such as Savannah or Charleston. Because of its later development, many of the city's landmarks share architectural characteristics with buildings in the Northeast or Midwest, as they were designed at a time of shared national architectural styles. During the late 20th century, Atlanta embraced the global trend of modern architecture, especially for commercial and institutional structures. Examples include the State of Georgia Building built in 1966, and the Georgia-Pacific Tower in 1982. Many of the most notable examples from this period were designed by world renowned Atlanta architect John Portman. Most of the buildings that define the downtown skyline were designed by Portman during this period, including the Westin Peachtree Plaza and the Atlanta Marriott Marquis. In the latter half of the 1980s, Atlanta became one of the early homes of postmodern buildings that reintroduced classical elements to their designs. Many of Atlanta's tallest skyscrapers were built in this period and style, displaying tapering spires or otherwise ornamented crowns, such as One Atlantic Center (1987), 191 Peachtree Tower (1991), and the Four Seasons Hotel Atlanta (1992). Also completed during the era is the Portman-designed Bank of America Plaza built in 1992. At , it is the tallest building in the city and the 14th-tallest in the United States. The city's embrace of modern architecture has often translated into an ambivalent approach toward historic preservation, leading to the destruction of many notable architectural landmarks. These include the Equitable Building (1892–1971), Terminal Station (1905–1972), and the Carnegie Library (1902–1977). In the mid-1970s, the Fox Theatre, now a cultural icon of the city, would have met the same fate if not for a grassroots effort to save it. More recently, preservationists may have made some inroads. For example, in 2016 activists convinced the Atlanta City Council not to demolish the Atlanta-Fulton Central Library, the last building designed by noted architect Marcel Breuer. Atlanta is divided into 242 officially defined neighborhoods. The city contains three major high-rise districts, which form a north–south axis along Peachtree: Downtown, Midtown, and Buckhead. Surrounding these high-density districts are leafy, low-density neighborhoods, most of which are dominated by single-family homes. Downtown Atlanta contains the most office space in the metro area, much of it occupied by government entities. Downtown is home to the city's sporting venues and many of its tourist attractions. Midtown Atlanta is the city's second-largest business district, containing the offices of many of the region's law firms. Midtown is known for its art institutions, cultural attractions, institutions of higher education, and dense form. Buckhead, the city's uptown district, is north of Downtown and the city's third-largest business district. The district is marked by an urbanized core along Peachtree Road, surrounded by suburban single-family neighborhoods situated among woods and rolling hills. Surrounding Atlanta's three high-rise districts are the city's low- and medium-density neighborhoods, where the craftsman bungalow single-family home is dominant. The eastside is marked by historic streetcar suburbs, built from the 1890s–1930s as havens for the upper middle class. These neighborhoods, many of which contain their own villages encircled by shaded, architecturally distinct residential streets, include the Victorian Inman Park, Bohemian East Atlanta, and eclectic Old Fourth Ward. On the westside and along the BeltLine on the eastside, former warehouses and factories have been converted into housing, retail space, and art galleries, transforming the once-industrial areas such as West Midtown into model neighborhoods for smart growth, historic rehabilitation, and infill construction. In southwest Atlanta, neighborhoods closer to downtown originated as streetcar suburbs, including the historic West End, while those farther from downtown retain a postwar suburban layout. These include Collier Heights and Cascade Heights, home to much of the city's affluent African-American population. Northwest Atlanta contains the areas of the city to west of Marietta Boulevard and to the north of Martin Luther King Jr. Drive, including those neighborhoods remote to downtown, such as Riverside, Bolton and Whittier Mill. The latter is one of Atlanta's designated Landmark Historical Neighborhoods. Vine City, though technically Northwest, adjoins the city's Downtown area and has recently been the target of community outreach programs and economic development initiatives. Gentrification of the city's neighborhoods is one of the more controversial and transformative forces shaping contemporary Atlanta. The gentrification of Atlanta has its origins in the 1970s, after many of Atlanta's neighborhoods had declined and suffered the urban decay that affected other major American cities in the mid-20th century. When neighborhood opposition successfully prevented two freeways from being built through the city's east side in 1975, the area became the starting point for Atlanta's gentrification. After Atlanta was awarded the Olympic games in 1990, gentrification expanded into other parts of the city, stimulated by infrastructure improvements undertaken in preparation for the games. New development post-2000 has been aided by the Atlanta Housing Authority's eradication of the city's public housing. As noted above, it allowed development of these sites for mixed-income housing, requiring developers to reserve a considerable portion for affordable housing units. It has also provided for other former residents to be given vouchers to gain housing in other areas. Construction of the Beltline has stimulated new and related development along its path. Climate Under the Köppen classification, Atlanta has a humid subtropical climate (Cfa) with four distinct seasons and generous precipitation year-round, typical for the Upland South; the city is situated in USDA Plant Hardiness Zone 8a, with the northern and western suburbs, as well as part of Midtown transitioning to 7b. Summers are hot and humid, with temperatures somewhat moderated by the city's elevation. Winters are overall mild but variable, occasionally susceptible to snowstorms even if in small quantities on several occasions, unlike the central and southern portions of the state. Warm air from the Gulf of Mexico can bring spring-like highs while strong Arctic air masses can push lows into the teens °F (−7 to −12 °C). July averages , with high temperatures reaching on an average of 47 days per year, though readings are not seen most years. January averages , with temperatures in the suburbs slightly cooler due largely to the urban heat island effect. Lows at or below freezing can be expected 36 nights annually, but the last occurrences of temperatures below were December 24, 2022, and January 2014, eight years apart. Extremes range from on February 13, 1899 to on June 30, 2012. Average dewpoints in the summer range from in June to in July. Typical of the southeastern U.S., Atlanta receives abundant rainfall that is evenly distributed throughout the year, though late spring and early fall are somewhat drier. The average annual precipitation is , while snowfall is typically light and rare with a normal of per winter. The heaviest single snowfall occurred on January 23, 1940, with around of snow. However, ice storms usually cause more problems than snowfall does, the most severe occurring on January 7, 1973. Tornadoes are rare in the city itself, but the March 14, 2008 EF2 tornado damaged prominent structures in downtown Atlanta. Demographics Population The 2020 United States census reported that Atlanta had a population of 498,715. The population density was 3,685.45 persons per square mile (1,422.95/km2). The racial makeup of Atlanta (including Hispanics) was 51.0% Black or African American, 40.9% White, 4.2% Asian and 0.3% Native American, and 1.0% from other races. 2.4% of the population reported two or more races. Hispanics of any race made up 6.0% of the city's population. The median income for a household in the city was $66,657. The per capita income for the city was $54,414. 20.2% percent of the population was living below the poverty line. In the 1920s, the Black population began to grow in Southern metropolitan cities like Atlanta, Birmingham, Houston, and Memphis. The New Great Migration brought an insurgence of African Americans from California and the North to the Atlanta area. It has long been known as a center of African-American political power, education, economic prosperity, and culture, often called a Black mecca. In the 1990s, Atlanta started to experience Black flight to its suburbs. A massive influx of African Americans were moving to the suburbs primarily seeking a lower cost of living or better public schools. The African American share of Atlanta's population is the fastest declining of any racial group. From 2000 to 2020, the city's African American population shrank from 61% of the city's population in 2000 to 47% in 2020, as the city's overall population increased. Blacks made up nine percent of new Atlanta residents between 2010 and 2020. Atlanta is also home to a sizable foreign-born Black population. With many notable investments occurring in Atlanta initiated by the 1996 Olympics, the White population of Atlanta began to rebound after several decades of white flight to Atlanta's suburbs. Between 2000 and 2020, the proportion of Whites in the city had strong growth. In two decades, Atlanta's White population grew from 33% to 39% of the city's population. Whites made up the majority of new Atlanta residents between 2010 and 2020. The Hispanic and Latino populations in Atlanta and metro Atlanta are growing strong. The largest Hispanic ancestries in Atlanta are Mexican, Puerto Rican and Cuban. There is a growing presence of Mexicans throughout the 10-county region. Mexicans are also concentrated along the Buford Highway and I-85 corridor, first noted in the 1990 census, have expanded and now extend well into Gwinnett County. Metro Atlanta has the 19th largest Hispanic population in the country. The Atlanta area also has a fast growing Asian American population. Most Asians in Atlanta are of Indian, Vietnamese, Chinese, Korean, Filipino, Pakistani and Japanese descent. Early immigrants in the Atlanta area were mostly Jews and Greeks. Since 1970, the Hispanic immigrant population, especially Mexicans, has experienced the most rapid growth, particularly in Gwinnett, Cobb, and DeKalb counties. Since 2010, the Atlanta area has seen very notable growth with immigrants from India, China, South Korea, and Jamaica. Other notable countries immigrants come from are Vietnam, Eritrea, Nigeria, the Arabian gulf, Ukraine and Poland. Within a few decades, and in keeping with national trends, immigrants from England, Ireland, and German-speaking central Europe were no longer the majority of Atlanta's foreign-born population. The city's Italians included immigrants from northern Italy, many of whom had been in Atlanta since the 1890s; more recent arrivals from southern Italy; and Sephardic Jews from the Isle of Rhodes, which Italy had seized from Turkey in 1912. Of the total population five years and older, 83.3% spoke only English at home, while 8.8% spoke Spanish, 3.9% another Indo-European language, and 2.8% an Asian language. 7.3% of Atlantans were born abroad (86th in the US). Atlanta's dialect has traditionally been a variation of Southern American English. The Chattahoochee River long formed a border between the Coastal Southern and Southern Appalachian dialects. Because of the development of corporate headquarters in the region, attracting migrants from other areas of the country, by 2003, Atlanta magazine concluded that Atlanta had become significantly "de-Southernized". A Southern accent was considered a handicap in some circumstances. In general, Southern accents are less prevalent among residents of the city and inner suburbs and among younger people; they are more common in the outer suburbs and among older people. At the same time, some residents of the city speak in Southern variations of African-American English. Sexual orientation and gender identity Atlanta has a thriving and diverse lesbian, gay, bisexual, and transgender (LGBT) community. According to a survey by the Williams Institute, Atlanta ranked third among major American cities, behind San Francisco and slightly behind Seattle, with 12.8% of the city's total population identifying as LGB. The Midtown and Cheshire Bridge areas have historically been the epicenters of LGBT culture in Atlanta. Atlanta formed a reputation for being a place of tolerance after former mayor Ivan Allen Jr. dubbed it "the city too busy to hate" in the 1960s (referring to racial relations). Atlanta has consistently scored 100% on the Human Rights Campaign's Municipal Equality Index that measures how inclusive a city's laws, policies and services are for LGBT people who live and work there. Religion Religion in Atlanta, while historically centered on Protestant Christianity, now encompasses many faiths, as a result of the city and metro area's increasingly international population. Some 63% of residents identified as some type of Protestant according to the Pew Research Center in 2014, but in recent decades the Catholic Church has increased in numbers and influence because of new migrants to the region. Metro Atlanta also has numerous ethnic or national Christian congregations, including Korean and Indian churches. Per the Public Religion Research Institute in 2020, overall, 73% of the population identify with some tradition or denomination of Christianity; despite continuing religious diversification, historically African American Protestant churches continue prevalence in the whole metropolitan area alongside historic Black Catholic churches. The larger non-Christian faiths according to both studies are Judaism, Islam, and Hinduism. Overall, there are over 1,000 places of worship within Atlanta. Economy With a GDP of $385 billion, the Atlanta metropolitan area's economy is the 11th-largest in the country and the 22nd-largest in the world. Corporate operations play a major role in Atlanta's economy, as the city claims the nation's third-largest concentration of Fortune 500 companies (tied for third with Chicago). It also hosts the global headquarters of several corporations such as The Coca-Cola Company, The Home Depot, Delta Air Lines, Arby's, AT&T Mobility, Georgia-Pacific, Chick-fil-A, Church's Chicken, Dunkin Donuts, Norfolk Southern Railway, Mercedes-Benz USA, NAPA Auto Parts, Papa Johns, Porsche AG, Newell Brands, Marble Slab Creamery, and UPS. Over 75% of Fortune 1000 companies conduct business operations in the city's metro area, and the region hosts offices of over 1,250 multinational corporations. Many corporations are drawn to the city by its educated workforce; , 45% of adults aged 25 or older residing in the city have at least four-year college degrees, compared to the national average of 28%. Atlanta started as a railroad town, and logistics has been a major component of the city's economy to this day. Atlanta serves as an important rail junction and contains major classification yards for Norfolk Southern and CSX. Since its construction in the 1950s, Hartsfield–Jackson Atlanta International Airport (ATL) has served as a key engine of the city's economic growth. Delta Air Lines, the city's largest employer and the metro area's third-largest, operates the world's largest airline hub at Hartsfield-Jackson, and it has helped make it the world's busiest airport, in terms of both passenger traffic and aircraft operations. Partly due to the airport, Atlanta has been also a hub for diplomatic missions; , the city contains 26 consulates general, the seventh-highest concentration of diplomatic missions in the US. Broadcasting is also an important aspect of Atlanta's economy. In the 1980s, media mogul Ted Turner founded the Cable News Network (CNN), Turner Network Television (TNT), HLN (HLN), Turner Classic Movies (TCM), Cartoon Network (CN), TruTV (truTV) and the Turner Broadcasting System (TBS) in the city. Around the same time, Cox Enterprises, now the nation's third-largest cable television service and the publisher of over a dozen American newspapers, moved its headquarters to the city. Notable sports networks headquartered in Atlanta include Warner Bros. Discovery Sports, NBA TV, Bally Sports South, and Bally Sports Southeast. The Weather Channel is also based just outside of the city in suburban Cobb County. Information technology (IT) has become an increasingly important part of Atlanta's economic output, earning the city the nickname the "Silicon peach". , Atlanta contains the fourth-largest concentration of IT jobs in the US, numbering 85,000+. The city is also ranked as the sixth fastest-growing for IT jobs, with an employment growth of 4.8% in 2012 and a three-year growth near 9%, or 16,000 jobs. Companies are drawn to Atlanta's lower costs and educated workforce. Recently, Atlanta has been the center for film and television production, largely because of the Georgia Entertainment Industry Investment Act, which awards qualified productions a transferable income tax credit of 20% of all in-state costs for film and television investments of $500,000 or more. Film and television production facilities based in Atlanta include Turner Studios, Pinewood Atlanta Studios, Tyler Perry Studios, Williams Street Productions, and the EUE/Screen Gems soundstages. Film and television production injected $9.5 billion into Georgia's economy in 2017, with Atlanta garnering most of the projects. Atlanta has emerged as the all-time most popular destination for film production in the United States and one of the 10 most popular destinations globally. Compared to other American cities, Atlanta's economy in the past had been disproportionately affected by the 2008 financial crisis and the subsequent recession, with the city's economy being ranked 68th among 100 American cities in a September 2014 report due to an elevated unemployment rate, declining real income levels, and a depressed housing market. From 2010 to 2011, Atlanta saw a 0.9% contraction in employment and plateauing income growth at 0.4%. Although unemployment had decreased to 7% by late 2014, this was still higher than the national unemployment rate of 5.8% Atlanta's housing market has also struggled, with home prices dropping by 2.1% in January 2012, reaching levels not seen since 1996. Compared with a year earlier, the average home price in Atlanta plummeted to 17.3% in February 2012, thus becoming the largest annual drop in the history of the index for any American or global city. The decline in home prices prompted some economists to deem Atlanta the worst housing market in the nation at the height of the depression. Nevertheless, the city's real estate market has resurged since 2012, so much median home value and rent growth significantly outpaced the national average by 2018, thanks to a rapidly-growing regional economy. Arts and culture Atlanta is noted for its lack of Southern culture. This is due to a large population of migrants from other parts of the U.S., in addition to many recent immigrants to the U.S. who have made the metropolitan area their home, establishing Atlanta as the cultural and economic hub of an increasingly multi-cultural metropolitan area. This unique cultural combination reveals itself in the arts district of Midtown, the quirky neighborhoods on the city's eastside, and the multi-ethnic enclaves found along Buford Highway. Arts and theater Atlanta is one of few United States cities with permanent, professional, and resident companies in all major performing arts disciplines: opera (Atlanta Opera), ballet (Atlanta Ballet), orchestral music (Atlanta Symphony Orchestra), and theater (the Alliance Theatre). Atlanta attracts many touring Broadway acts, concerts, shows, and exhibitions catering to a variety of interests. Atlanta's performing arts district is concentrated in Midtown Atlanta at the Woodruff Arts Center, which is home to the Atlanta Symphony Orchestra and the Alliance Theatre. The city frequently hosts touring Broadway acts, especially at The Fox Theatre, a historic landmark among the highest-grossing theaters of its size. As a national center for the arts, Atlanta is home to significant art museums and institutions. The renowned High Museum of Art is arguably the South's leading art museum. The Museum of Design Atlanta (MODA) and the SCAD FASH Museum of Fashion + Film are the only such museums in the Southeast. Contemporary art museums include the Atlanta Contemporary Art Center and the Museum of Contemporary Art of Georgia. Institutions of higher education contribute to Atlanta's art scene, with the Savannah College of Art and Design's Atlanta campus providing the city's arts community with a steady stream of curators, and Emory University's Michael C. Carlos Museum containing the largest collection of ancient art in the Southeast. In nearby Athens is the Georgia Museum of Art that is associated with the University of Georgia and is both an academic museum and the official art museum of the state of Georgia. Atlanta has become one of the U.S.'s best cities for street art in recent years. It is home to Living Walls, an annual street art conference and the Outerspace Project, an annual event series that merges public art, live music, design, action sports, and culture. Examples of street art in Atlanta can be found on the Atlanta Street Art Map. Music Atlanta has played a major or contributing role in the development of various genres of American music at different points in the city's history. Beginning as early as the 1920s, Atlanta emerged as a center for country music, which was brought to the city by migrants from Appalachia. During the countercultural 1960s, Atlanta hosted the Atlanta International Pop Festival, with the 1969 festival taking place more than a month before Woodstock and featuring many of the same bands. The city was also a center for Southern rock during its 1970s heyday: the Allman Brothers Band's hit instrumental "Hot 'Lanta" is an ode to the city, while Lynyrd Skynyrd's famous live rendition of "Free Bird" was recorded at the Fox Theatre in 1976, with lead singer Ronnie Van Zant directing the band to "play it pretty for Atlanta". During the 1980s, Atlanta had an active punk rock scene centered on two of the city's music venues, 688 Club and the Metroplex, and Atlanta famously played host to the Sex Pistols' first U.S. show, which was performed at the Great Southeastern Music Hall. The 1990s saw the city produce major mainstream acts across many different musical genres. Country music artist Travis Tritt, and R&B sensations Xscape, TLC, Usher and Toni Braxton, were just some of the musicians who call Atlanta home. The city also gave birth to Atlanta hip hop, a sub-genre that gained relevance and success with the introduction of the home-grown Atlantans known as Outkast, along with other Dungeon Family artists such as Organized Noize and Goodie Mob; however, it was not until the 2000s that Atlanta moved "from the margins to becoming hip-hop's center of gravity with another sub-genre called Crunk, part of a larger shift in hip-hop innovation to the South and East". Trap music is another sub-genre of hip-hop that started in the Atlanta area. In the 2000s, Atlanta was recognized by the Brooklyn-based Vice magazine for its indie rock scene, which revolves around the various live music venues found on the city's alternative eastside. To facilitate further local development, the state government provides qualified businesses and productions a 15% transferable income tax credit for in-state costs of music investments. Film and television As the national leader for motion picture and television production, and a top ten global leader, Atlanta plays a significant role in the entertainment industry. Atlanta is also considered a hub for filmmakers of color and houses Tyler Perry Studios (first African-American owned major studio) and Areu Bros. Studios (first Latino-American owned major studio). Atlanta doubles for other parts of the world and fictional settlements in blockbuster productions, among them the newer titles from The Fast and the Furious franchise and Marvel features such as Ant-Man (2015), Captain America: Civil War (2016), Black Panther and Avengers: Infinity War (both 2018). On the other hand, Gone With the Wind (1939), Smokey and the Bandit (1977), Sharky's Machine (1981), The Slugger's Wife (1985), Driving Miss Daisy (1989), ATL (2006), Ride Along (2014) and Baby Driver (2017) are among several notable examples of films actually set in Atlanta. It was announced in 2022 a film about the 1956 Sugar Bowl and Atlanta riots would be produced here. The city also provides the backdrop for shows such as Ozark, Watchmen, The Walking Dead, Stranger Things, Love is Blind, Star, Dolly Parton's Heartstrings, The Outsider, The Vampire Diaries, The Real Housewives of Atlanta, Love & Hip Hop Atlanta and Atlanta, in addition to a myriad of animated and reality television programming.

Tourism , Atlanta is the seventh-most visited city in the United States, with over 35 million visitors per year. Although the most popular attraction among visitors to Atlanta is the Georgia Aquarium, and until 2012, the world's largest indoor aquarium, Atlanta's tourism industry is mostly driven by the city's history museums and outdoor attractions. Atlanta contains a notable number of historical museums and sites, including the Martin Luther King Jr. National Historical Park, which includes the preserved childhood home of Dr. Martin Luther King Jr., as well as his final resting place; the Atlanta Cyclorama & Civil War Museum, which houses a massive painting and diorama in-the-round, with a rotating central audience platform, depicting the Battle of Atlanta in the Civil War; the World of Coca-Cola, featuring the history of the world-famous soft drink brand and its well-known advertising; the College Football Hall of Fame, which honors college football and its athletes; the National Center for Civil and Human Rights, which explores the civil rights movement and its connection to contemporary human rights movements throughout the world; the Carter Center and Presidential Library, housing U.S. President Jimmy Carter's papers and other material relating to the Carter administration and the Carter family's life; and the Margaret Mitchell House and Museum, where Mitchell wrote the best-selling novel Gone with the Wind.

Home to the nation's largest collections of gorillas and orangutans, the zoo is one of only four zoos in the U.S. to house giant pandas. Festivals showcasing arts and crafts, film, and music, including the Atlanta Dogwood Festival, the Atlanta Film Festival, and Music Midtown, respectively, are also popular with tourists. Tourists are drawn to the city's culinary scene, which comprises a mix of urban establishments garnering national attention, ethnic restaurants serving cuisine from every corner of the world, and traditional eateries specializing in Southern dining. Since the turn of the 21st century, Atlanta has emerged as a sophisticated restaurant town. Many restaurants opened in the city's gentrifying neighborhoods have received praise at the national level, including Bocado, Bacchanalia, and Miller Union in West Midtown, Empire State South in Midtown, and Two Urban Licks and Rathbun's on the east side. In 2011, The New York Times characterized Empire State South and Miller Union as reflecting "a new kind of sophisticated Southern sensibility centered on the farm but experienced in the city". Visitors seeking to sample international Atlanta are directed to Buford Highway, the city's international corridor, and suburban Gwinnett County. There, the nearly-million immigrants that make Atlanta home have established various authentic ethnic restaurants representing virtually every nationality on the globe. For traditional Southern fare, one of the city's most famous establishments is The Varsity, a long-lived fast food chain and the world's largest drive-in restaurant. Mary Mac's Tea Room and Paschal's are more formal destinations for Southern food. Cuisine Atlanta is best known for its barbecue, hamburgers, Southern fried chicken, and lemon pepper wings. Buford Highway is home to many ethnic cuisines such as Mexican and Asian foods. Sports Sports are an important part of the culture of Atlanta.

Infrastructure Transportation Atlanta's transportation infrastructure comprises a complex network that includes a heavy rail rapid transit system, a light rail streetcar loop, a multi-county bus system, Amtrak service via the Crescent, multiple freight train lines, an Interstate Highway System, several airports, including the world's busiest, and over of bike paths. Atlanta has a network of freeways that radiate out from the city, and automobiles are the dominant means of transportation in the region. Three major interstate highways converge in Atlanta: I-20 (east-west), I-75 (northwest-southeast), and I-85 (northeast-southwest). The latter two combine in the middle of the city to form the Downtown Connector (I-75/85), which carries more than 340,000 vehicles per day and is one of the most congested segments of interstate highway in the United States. Atlanta is mostly encircled by Interstate 285, a beltway locally known as "the Perimeter" that has come to mark the boundary between "Inside the Perimeter" (ITP), the city and close-in suburbs, and "Outside the Perimeter" (OTP), the outer suburbs and exurbs. The heavy reliance on automobiles for transportation in Atlanta has resulted in traffic, commute, and air pollution rates that rank among the worst in the country. The City of Atlanta has a higher than average percentage of households without a car. In 2015, 15.2 percent of Atlanta households lacked a car, and increased slightly to 16.4 percent in 2016. The national average is 8.7 percent in 2016. Atlanta averaged 1.31 cars per household in 2016, compared to a national average of 1.8. The Metropolitan Atlanta Rapid Transit Authority (MARTA) provides public transportation in the form of buses, heavy rail, and a downtown light rail loop. Notwithstanding heavy automotive usage in Atlanta, the city's subway system is the eighth busiest in the country. MARTA rail lines connect key destinations, such as the airport, Downtown, Midtown, Buckhead, and Perimeter Center. However, significant destinations, such as Emory University and Cumberland, remain unserved. As a result, a 2011 Brookings Institution study placed Atlanta 91st of 100 metro areas for transit accessibility. Emory University operates its Cliff shuttle buses with 200,000 boardings per month, while private minibuses supply Buford Highway. Amtrak, the national rail passenger system, provides service to Atlanta via the Crescent train (New York–New Orleans), which stops at Peachtree Station. In 2014, the Atlanta Streetcar opened to the public. The streetcar's line, which is also known as the Downtown Loop, runs around the downtown tourist areas of Peachtree Center, Centennial Olympic Park, the Martin Luther King Jr. National Historical Park, and Sweet Auburn. The Atlanta Streetcar line is also being expanded on in the coming years to include a wider range of Atlanta's neighborhoods and important places of interest, with a total of over of track in the plan. Hartsfield–Jackson Atlanta International Airport is the world's busiest airport as measured by passenger traffic and aircraft traffic. The facility offers air service to over 150 U.S. destinations and more than 75 international destinations in 50 countries, with over 2,500 arrivals and departures daily. Delta Air Lines maintains its largest hub at the airport. Situated () south of downtown, the airport covers most of the land inside a wedge formed by Interstate 75, Interstate 85, and Interstate 285. Cycling is a growing mode of transportation in Atlanta, more than doubling since 2009, when it comprised 1.1% of all commutes (up from 0.3% in 2000). Although Atlanta's lack of bike lanes and hilly topography may deter many residents from cycling, the city's transportation plan calls for the construction of of bike lanes by 2020, with the BeltLine helping to achieve this goal. In 2012, Atlanta's first "bike track" was constructed on 10th Street in Midtown. The two lane bike track runs from Monroe Drive west to Charles Allen Drive, with connections to the Beltline and Piedmont Park. Starting in June 2016, Atlanta received a bike sharing program, known as Relay Bike Share, with 100 bikes in Downtown and Midtown, which expanded to 500 bikes at 65 stations as of April 2017. According to the 2016 American Community Survey (five-year average), 68.6% of working city of Atlanta residents commuted by driving alone, 7% carpooled, 10% used public transportation, and 4.6% walked. About 2.1% used all other forms of transportation, including taxi, bicycle, and motorcycle. About 7.6% worked at home. The city has also become one of a handful of "scooter capitals", where companies like Lime and Bird have gained a major foothold by placing electric scooters on street corners and byways. Emergency services The city is served by the Atlanta Police Department (APD) , which numbers 2,000 officers and oversaw a 40% decrease in the city's crime rate between 2001 and 2009. In 2012, Forbes ranked Atlanta as the 6th most dangerous American city but by 2023 the city dropped out of its top 10.Despite some improvement in crime, street gangs have continued to plague the city since the 1980s. In 2022, there was a 200% increase in gang-related charges in the city. In 2023, it was estimated that about 1,000 gangs in the Atlanta area were responsible for at least 70% of all crime including identity theft, credit card fraud, and human trafficking. The Georgia Bureau of Investigation Gang Task Force in partnership with the APD is leading efforts in dismantling gang activity and arresting culprits. The Atlanta Fire Rescue Department provides fire protection and first responder emergency medical services to the city from its 35 fire stations. In 2017, AFRD responded to over 100,000 calls for service over a coverage area of . The department also protects Hartsfield–Jackson with five fire stations on the property, serving over 1 million passengers from over 100 countries. The department protects over 3000 high-rise buildings, of the rapid rail system, and of interstate highway. Emergency ambulance services are provided to city residents by hospital-based Grady EMS (Fulton County), and American Medical Response (DeKalb County). Atlanta in January 2017 declared the city was a "welcoming city" and "will remain open and welcoming to all". Nonetheless, Atlanta does not consider itself to be a "sanctuary city". Atlanta Mayor Keisha Lance Bottoms said: "Our city does not support ICE. We don't have a relationship with the U.S. Marshal[s] Service. We closed our detention center to ICE detainees, and we would not pick up people on an immigration violation." Notable people Tree canopy Atlanta has a reputation as a "city in a forest" due to an abundance of trees that is rare among major cities. The city's main street is named after a tree, and beyond the Downtown, Midtown, and Buckhead business districts, the skyline gives way to a dense canopy of woods that spreads into the suburbs. The city is home to the Atlanta Dogwood Festival, an annual arts and crafts festival held one weekend during early April, when the native dogwoods are in bloom. The nickname is factually accurate, as vegetation covers 47.9% of the city as of 2017, the highest among all major American cities, and well above the national average of 27%. Atlanta's tree coverage does not go unnoticed—it was the main reason cited by National Geographic in naming Atlanta a "Place of a Lifetime". The city's lush tree canopy, which filters out pollutants and cools sidewalks and buildings, has increasingly been under assault from man and nature due to heavy rains, drought, aged forests, new pests, and urban construction. A 2001 study found Atlanta's heavy tree cover declined from 48% in 1974 to 38% in 1996. Community organizations and the city government are addressing the problem. Trees Atlanta, a non-profit organization founded in 1985, has planted and distributed over 113,000 shade trees in the city, and Atlanta's government has awarded $130,000 in grants to neighborhood groups to plant trees. Fees are additionally imposed on developers that remove trees on their property per a citywide ordinance, active since 1993.

AIM-7 Sparrow

The AIM-7 Sparrow (Air Intercept Missile) is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers, and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made it difficult to achieve lock-on at the missile's effective range. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat the enemy fighter would often approach within the range of shorter-range infrared homing missiles while the launching aircraft had to continue flying towards its target. Additionally, early models were only effective against targets at roughly the same or higher altitudes, below which reflections from the ground became a problem. A number of upgraded Sparrow designs were developed to address these issues. In the early 1970s, the RAF developed the Skyflash version with an inverse monopulse seeker and improved motor, while the Italian Air Force introduced the similar Aspide. Both could be fired at targets below the launching fighter ("look-down, shoot down"), were more resistant to countermeasures, and were much more accurate in the terminal phase. This basic concept then became part of the US Sparrows in the M model (for monopulse) and some of these were later updated as the P model, the last to be produced in the US. Aspides sold to China resulted in the locally produced PL-11. The Japan Self-Defense Forces also employ the Sparrow missile, though it is being phased out and replaced by the Mitsubishi AAM-4. The Sparrow was also used as the basis for a surface-to-air missile, the RIM-7 Sea Sparrow, used by a number of navies for air defense. Fired at low altitude and flying directly at its target, though, the range of the missile in this role is greatly reduced because of the higher air density of the lower atmosphere. With the retirement of the Sparrow in the air-to-air role, a new version of the Sea Sparrow was produced to address this concern, producing the larger and more capable RIM-162 ESSM. Development Sparrow I The Sparrow emerged from a late-1940s United States Navy program to develop a guided rocket weapon for air-to-air use. In 1947 the Navy contracted Sperry to build a beam-riding version of a standard HVAR, the standard unguided aerial rocket, under Project Hotshot. The weapon was initially dubbed KAS-1, then AAM-2, and — from 1948 on — AAM-N-2. The airframe was developed by the Douglas Aircraft Company. The diameter of the HVAR proved to be inadequate for the electronics, leading Douglas to expand the missile's airframe to diameter. The prototype weapon began unpowered flight tests in 1947, and made its first aerial interception in 1952. After a protracted development cycle the initial AAM-N-2 Sparrow entered limited operational service in 1954 with specially modified Douglas F3D Skyknight all-weather carrier night fighters. In 1956, they were joined by the McDonnell F3H-2M Demon and Vought F7U Cutlass fighter aircraft. Compared to the modern versions, the Sparrow I was more streamlined and featured a bullet-shaped airframe with a long pointed nose. Sparrow I was a limited and rather primitive weapon. The limitations of beam-riding guidance (which was slaved to an optical sight on single-seater fighters and to radar on night fighters) restricted the missile to attacks against targets flying a straight course and made it essentially useless against a maneuvering target. Only about 2,000 rounds were produced to this standard. Sparrow II As early as 1950 Douglas examined equipping the Sparrow with an active radar seeker, initially known as XAAM-N-2a Sparrow II, the original retroactively becoming Sparrow I. In 1952 it was given the new code AAM-N-3. The active radar made the Sparrow II a "fire and forget" weapon, allowing several to be fired at separate targets at the same time. By 1955 Douglas proposed going ahead with development, intending it to be the primary weapon for the F5D Skylancer interceptor. It was later selected, with some controversy, to be the primary weapon for the Canadian Avro Arrow supersonic interceptor, along with the new Astra fire-control system. For Canadian use and as a second source for US missiles, Canadair was selected to build the missiles in Quebec. The small size of the missile forebody and the K-band AN/APQ-64-radar limited performance, and it was never able to work in testing. After considerable development and test firings in the U.S. and Canada, Douglas abandoned development in 1956. Canadair continued development until the Arrow was cancelled in 1959. Sparrow X A subvariant of the Sparrow I armed with the same nuclear warhead as the MB-1 Genie was proposed in 1958 but was cancelled shortly thereafter. Sparrow III Concurrently with the development of the Sparrow I, in 1951 Raytheon began work on a semi-active radar-homing version, the AAM-N-6 Sparrow III. The first of these weapons entered United States Navy service in 1958. The AAM-N-6a was similar to the -6, but used a new Thiokol liquid-fuel rocket engine for improved performance. It also included changes to the guidance electronics to make it effective at higher closing speeds. The -6a was also selected to arm the Air Force's F-110A Spectre (F-4 Phantom) fighters in 1962, known to them as the AIM-101. It entered production in 1959, with 7500 being built. With a reversion to a Rocketdyne solid-fuel motor, the AAM-N-6b started production in 1963. The new motor significantly increased the maximum range to for head-on attacks. During this year the Air Force and Navy agreed on standardized naming conventions for their missiles. The Sparrows became the AIM-7 series. The original Sparrow I and aborted Sparrow II became the AIM-7A and AIM-7B, despite both being out of service. The -6, -6a, and -6b became the AIM-7C, AIM-7D, and AIM-7E respectively. 25,000 AIM-7Es were produced and saw extensive use during the Vietnam War, where its performance was considered disappointing. The mixed results were a combination of reliability problems (exacerbated by the tropical climate), limited pilot training in fighter-to-fighter combat, and restrictive rules of engagement that generally prohibited BVR (beyond visual range) engagements. The Pk (kill probability) of the AIM-7E was less than 10%; US fighter pilots shot down 59 aircraft out of the 612 Sparrows fired. Of the 612 AIM-7D/E/E-2 missiles fired, 97 (or 15.8%) hit their targets, resulting in 56 (or 9.2%) kills. Two kills were obtained beyond visual range. In 1969 an improved version, the E-2, was introduced with clipped wings and various changes to the fuzing. Considered a "dogfight Sparrow", the AIM-7E-2 was intended to be used at shorter ranges where the missile was still travelling at high speeds, and in the head-on aspect, making it much more useful in the visual limitations imposed on the engagements. Even so, its kill rate was only 13% in combat, leading to a practice of ripple-firing all four at once in hopes of increasing kill probability. Its worst tendency was to detonate prematurely about 1,000 feet ahead of the launching aircraft, but it also had many motor failures, erratic flights, and fuzing problems. An E-3 version included additional changes to the fuzing, and the E-4 featured a modified seeker for use with the F-14 Tomcat. Vietnam War (1965–1973) records Post Vietnam Improved versions of the AIM-7 were developed in the 1970s in an attempt to address the weapon's limitations. The AIM-7F, which entered service in 1976, had a dual-stage rocket motor for longer range, solid-state electronics for greatly improved reliability, and a larger warhead. Even this version had room for improvement, leading British Aerospace and the Italian firm Alenia to develop advanced versions of Sparrow with better performance and improved electronics as the BAe Skyflash and Alenia Aspide, respectively. The most common version of the Sparrow today, the AIM-7M, entered service in 1982 and featured a new inverse monopulse seeker (matching the capabilities of Skyflash), active radar proximity fuse, digital controls, improved ECM resistance, and better low-altitude performance. It was used to good advantage in the 1991 Gulf War, where it scored many USAF air-to-air kills. Of 44 missiles fired, 30 (68.2%) hit their intended targets resulting in 24/26 (54.5%/59.1%) kills. 19 kills were obtained beyond visual range. The AIM-7P is similar in most ways to the M versions, and was primarily an upgrade for existing M-series missiles. Changes were mainly to the software, improving low-level performance. A follow-on Block II upgrade added a new rear receiver allowing the missile to receive mid-course correction from the launching aircraft. Plans initially called for all M versions to be upgraded, but currently P's are being issued as required to replace M's lost or removed from the inventory. The final version of the missile was to have been the AIM-7R, which added an infrared homing seeker to an otherwise unchanged AIM-7P Block II. A general wind-down of the budget led to it being cancelled in 1997. The Sparrow is now being phased out with the availability of the active-radar AIM-120 AMRAAM, but is likely to remain in service for several years. Variants Foreign versions Canada As part of the Avro Canada CF-105 Arrow program, Canadair (now Bombardier) partnered with Douglas Aircraft Company in the development of the Sparrow II (AAM-N-3/AIM-7B). After Douglas dropped out of this program, Canadair continued on with it until the termination of the Arrow project. The AAM-N-3 Sparrow II was unique in that it had a fully active radar guidance system. This combined both a radar transmitter and receiver in the missile, making it unnecessary for the pilot to keep the aircraft aimed at the target after firing the missile, unlike Semi-active radar homing (SARH) missiles which require continuous radar-assisted guidance throughout flight. This allowed the aircraft that fired the AAM-N-3 to turn away, prosecute other targets, and/or escape from potential retaliatory missiles fired by the enemy aircraft during the time it took for the Sparrow to reach its target. Despite the significant advantages of this design over SARH guidance, all subsequent models of the Sparrow use semi-active radar homing. To accommodate the active radar guidance system, the AAM-N-3 Sparrow II had a much greater volume than its predecessor. Its size would subsequently set the precedent for all future Sparrow variants. In 1959, Canadair had completed five missiles based on airframes from Douglas, and built two models from scratch, when the program was cancelled with the cancellation of the Arrow. Italy The Italian company Finmeccanica (now Leonardo S.p.A.), Alenia Difesa licensed the AIM-7E Sparrow technology from the US, and produced its own version. Later in the 1980s, Alenia started to produce an improved version of the AIM-7 called the Aspide. Compared to the AIM-7E, it received an improved new monopulse guidance system that allowed for a better hit ratio and easier targeting of enemies at low altitude with ground-clutter confusion. It also received a new and more powerful engine and new control surfaces. These control surfaces were each independent of the others, giving the missile greatly improved maneuverability over the AIM-7E and the English Skyflash that still used dependent control surfaces. People's Republic of China The PL-11 and HQ-6 is a family of Chinese missiles developed by the Shanghai Academy of Science and Technology, largely based on the Italian Aspide version of the Sparrow missile. Soviet Union The Soviet Union acquired an AIM-7 in 1968 and a Vympel team started copying it as the K-25. The missile did not enter production as the R-23 was thought to have better versatility, range, signal processing logic, and immunity to interference. K-25 work ended in 1971, but analysis of the Sparrow was later used to inform the design of the Vympel R-27, particularly the servomechanisms and movable wings. UK British Aerospace (BAe) licensed the AIM-7E2 technology in the 1970s, producing the Skyflash missile. Skyflash used a Marconi XJ521 monopulse seeker together with improvements to the electronics. It was powered by the Aerojet Mk52 mod 2 rocket engine (later by the Rocketdyne Mk38 mod 4). Skyflash entered service with the Royal Air Force (RAF) on their Phantom FG.1/FGR.2 in 1978, and later on the Tornado F3. Skyflash was also exported to Sweden for use on their Viggen fighters. An upgraded version with active radar seeker, called Active Sky Flash, was proposed by BAe and Thomson-CSF, but did not receive funding because the RAF opted for other missiles. Design The Sparrow has four major sections: guidance section, warhead, control, and rocket motor (currently the Hercules MK-58 solid-propellant rocket motor). It has a cylindrical body with four wings at mid-body and four tail fins. Although the external dimensions of the Sparrow remained relatively unchanged from model to model, the internal components of newer missiles represent major improvements, with vastly increased capabilities. The warhead is of the continuous-rod type. As with other semi-active radar guided missiles, the missile does not generate radar signals, but instead homes in on reflected continuous-wave signals from the launch platform's radar. The receiver also senses the guidance radar to enable comparisons that enhance the missile's resistance to passive jamming. Principle of guidance The launching aircraft illuminates the target with its radar. In 1950s radars, these were single-target tracking devices using a nutating horn as part of the antenna, thereby sweeping the beam in a small cone. Signal processing is applied to determine the direction of maximum illumination, thereby developing a signal to steer the antenna toward the target. The missile detects the reflected signal from the target with a high-gain antenna in a similar fashion and steers the entire missile toward closure with the target. The missile guidance also samples a portion of the illuminating signal via rearward-pointing waveguides. The comparison of these two signals enabled logic circuits to determine the true target reflection signal, even if the target were to eject radar-reflecting chaff.

AIM-120 AMRAAM

The AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) (pronounced /æmɹæm/), is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance. It is a fire-and-forget weapon, unlike the previous generation Sparrow missiles which required full guidance from the firing aircraft. When an AMRAAM missile is launched, NATO pilots use the brevity code "Fox Three". more than 14,000 had been produced for the United States Air Force, the United States Navy, and 33 international customers. The AMRAAM has been used in several engagements, achieving 16 air-to-air kills in conflicts over Iraq, Bosnia, Kosovo, India, and Syria. Origins AIM-7 Sparrow MRM The AIM-7 Sparrow medium range missile (MRM) was purchased by the US Navy from original developer Hughes Aircraft in the 1950s as its first operational air-to-air missile with "beyond visual range" (BVR) capability. With an effective range of about , it was introduced as a radar beam-riding missile and then it was improved to a semi-active radar guided missile which would home in on reflections from a target illuminated by the radar of the launching aircraft. It was effective at visual to beyond visual range. The early beam riding versions of the Sparrow missiles were integrated onto the McDonnell F3H Demon and Vought F7U Cutlass, but the definitive AIM-7 Sparrow was the primary weapon for the all-weather McDonnell Douglas F-4 Phantom II fighter/interceptor, which lacked an internal gun in its U.S. Navy, U.S. Marine Corps, and early U.S. Air Force versions. The F-4 carried up to four AIM-7s in built-in recesses under its belly. Designed for use against non-maneuvering targets such as bombers, the missiles initially performed poorly against fighters over North Vietnam, and were progressively improved until they proved highly effective in dogfights. Together with the short-range, infrared-guided AIM-9 Sidewinder, they replaced the AIM-4 Falcon IR and radar guided series for use in air combat by the USAF as well. A disadvantage to semi-active homing was that only one target could be illuminated by the launching fighter plane at a time. Also, the launching aircraft had to remain pointed in the direction of the target (within the azimuth and elevation of its own radar set) which could be difficult or dangerous in air-to-air combat. An active-radar variant called the Sparrow II was developed to address these drawbacks, but the U.S. Navy pulled out of the project in 1956. The Royal Canadian Air Force, which took over development in the hopes of using the missile to arm their prospective Avro Canada CF-105 Arrow interceptor, soon followed in 1958. The electronics of the time simply could not be miniaturized enough to make Sparrow II a viable working weapon. It would take decades, and a new generation of digital electronics, to produce an effective active-radar air-to-air missile as compact as the Sparrow. AIM-54 Phoenix LRM The US Navy later developed the AIM-54 Phoenix long-range missile (LRM) for the fleet air defense mission. It was a large , Mach 5 missile designed to counter cruise missiles and the bombers that launched them. Originally intended for the straight-wing Douglas F6D Missileer and then the navalized General Dynamics–Grumman F-111B, it finally saw service with the Grumman F-14 Tomcat, the only fighter capable of carrying such a heavy missile. The Phoenix was the first US fire-and-forget, multiple-launch, radar-guided missile: one which used its own active guidance system to guide itself without help from the launch aircraft when it closed on its target. This, in theory, gave a Tomcat with a six-Phoenix load the unprecedented capability of tracking and destroying up to six targets beyond visual range, as far as away—the only US fighter with such capability. A full load of six Phoenix missiles and its dedicated launcher exceeded a typical Vietnam-era bomb load. Its service in the US Navy was primarily as a deterrent, as its use was hampered by restrictive rules of engagement in conflicts such as 1991 Gulf War, Southern Watch (enforcing no-fly zones), and Iraq War. The US Navy retired the Phoenix in 2004 in light of availability of the AIM-120 AMRAAM on the McDonnell Douglas F/A-18 Hornet and the pending retirement of the F-14 Tomcat from active service in late 2006. ACEVAL/AIMVAL The Department of Defense conducted an extensive evaluation of air combat tactics and missile technology from 1974 to 1978 at Nellis AFB using the F-14 Tomcat and F-15 Eagle equipped with Sparrow and Sidewinder missiles as the blue force and aggressor F-5E aircraft equipped with AIM-9L all-aspect Sidewinders as the red force. This joint test and evaluation (JT&E) was designated Air Combat Evaluation/Air Intercept Missile Evaluation (ACEVAL/AIMVAL). A principal finding was that the necessity to produce illumination for the Sparrow until impact resulted in the red force's being able to launch their all-aspect Sidewinders before impact, resulting in mutual kills. What was needed was Phoenix-type multiple-launch and terminal active capability in a Sparrow-size airframe. This led to a memorandum of agreement (MOA) with European allies (principally the UK and Germany for development) for the US to develop an advanced, medium-range, air-to-air missile with the USAF as lead service. The MOA also assigned responsibility for development of an advanced, short-range, air-to-air missile to the European team; this would become the British ASRAAM. Requirements By the 1990s, the reliability of the Sparrow had improved so much from the dismal days of Vietnam that it accounted for the largest number of aerial targets destroyed in the Desert Storm part of the Gulf War. But while the USAF had passed on the Phoenix and its own similar AIM-47 Falcon/Lockheed YF-12 to optimize dogfight performance, it still needed a multiple-launch fire-and-forget capability for the F-15 and F-16. The AMRAAM would need to be fitted on fighters as small as the F-16, and fit in the same spaces that were designed to fit the Sparrow on the F-4 Phantom. The European partners needed AMRAAM to be integrated on aircraft as small as the BAe Sea Harrier. The US Navy needed the AMRAAM to be carried on the F/A-18 Hornet and wanted capability for two to be carried on a launcher that normally carried one Sparrow to allow for more air-to-ground weapons. Finally, the AMRAAM became one of the primary air-to-air weapons of the new Lockheed Martin F-22 Raptor fighter, which needed to place all of its weapons into internal weapons bays in order to help achieve an extremely low radar cross-section. Development AMRAAM was developed as the result of an agreement (the Family of Weapons MOA, no longer in effect by 1990), among the United States and several other NATO nations to develop air-to-air missiles and to share production technology. Under this agreement, the U.S. was to develop the next generation medium range missile (AMRAAM) and Europe would develop the next generation short range missile (ASRAAM). Although Europe initially adopted the AMRAAM, an effort to develop the MDBA Meteor, a competitor to AMRAAM, was begun in UK. Eventually, the ASRAAM was developed solely by the British, but using another source for its infrared seeker. After protracted development, the deployment of AMRAAM (AIM-120A) began in September 1991 in US Air Force McDonnell Douglas F-15 Eagle fighter squadrons. The US Navy soon followed (in 1993) in its McDonnell Douglas F/A-18 Hornet squadrons. The Russian Air Force counterpart of AMRAAM is the somewhat similar R-77 (NATO codename AA-12 Adder), sometimes referred to in the West as the "AMRAAMski". Likewise, France began its own air-to-air missile development with the MICA concept that used a common airframe for separate radar-guided and infrared-guided versions. Operational history United States The AMRAAM was used for the first time on December 27, 1992, when a USAF General Dynamics F-16D Fighting Falcon shot down an Iraqi MiG-25 that violated the southern no-fly-zone. This missile had been returned from the flight line as defective a day earlier. The AMRAAM gained a second victory in January 1993 when an Iraqi MiG-23 was shot down by a USAF F-16C. On 28 February 1994, a Republika Srpska Air Force J-21 Jastreb aircraft was shot down by a USAF F-16C that was patrolling the UN-imposed no-fly zone over Bosnia. In that engagement, at least three other Serbian aircraft were shot down by USAF F-16Cs using AIM-9 missiles (Banja Luka incident). At that point, three launches in combat had resulted in three kills, resulting in the AMRAAM's being informally named "slammer" in the second half of the 1990s. In 1994, two USAF F-15 fighters patrolling Iraq's Northern No-Fly Zone mistook a pair of US Army Black Hawk helicopters for Iraqi helicopters, and shot them down. One was downed with an AIM-120, and one with an AIM-9 Sidewinder. In 1998 and 1999 AMRAAMs were again fired by USAF F-15 fighters at Iraqi aircraft violating the No-Fly-Zone, but this time they failed to hit their targets. During spring 1999, AMRAAMs saw their main combat action during Operation Allied Force, the Kosovo bombing campaign. Six Serbian MiG-29s were shot down by NATO (four USAF F-15Cs, one USAF F-16C, and one Dutch F-16A MLU), all of them using AIM-120 missiles (the supposed kill by the F-16C may have actually been friendly fire, a man-portable SA-7 fired by Serbian infantry). On 18 June 2017, a US Boeing F/A-18E Super Hornet engaged and shot down a Sukhoi Su-22 of the Syrian Air Force over northern Syria, using an AIM-120. An AIM-9X Sidewinder had failed to bring down the Syrian jet. Some sources have claimed the AIM-9X was decoyed by flares, although the F/A-18E pilot, Lieutenant Commander Michael “MOB” Tremel stated it was unclear why the AIM-9X failed, mentioning no use of flares by the Su-22, saying "I [lost] the smoke trail, and I have no idea what happened to the missile at that point". Turkey On 23 March 2014 a Turkish Air Force F-16 from 182 Squadron shot down a Syrian Arab Air Force MiG-23BN with an AIM-120C-7. On 24 November 2015 a Turkish Air Force F-16 shot down a Russian Su-24M strike aircraft with an AIM-120 missile over northern Syria after it allegedly crossed into Turkish airspace. On 1 March 2020, Turkish Air Force F-16s downed two Su-24s belonging to the Syrian Air Force using two AIM-120C-7s. On 3 March 2020, a Syrian Air Force L-39 was shot down over Idlib by Turkish Air Force F-16s from inside Turkish airspace with AIM-120C-7 at a distance of about . As of 2020, this has been the longest range AIM-120 kill. Pakistan On 27 February 2019, India stated that Pakistan Air Force (PAF) used AMRAAMs during Operation Swift Retort. Indian officials displayed fragments of an alleged AIM-120C-5 missile as a proof of its usage during the engagement. The only confirmed loss of the engagement was an Indian Air Force MiG-21, while Pakistan said it also shot down an Su-30MKI Flanker-H. IAF officials denied any loss of Su-30 MKI and also told Indian media that an IAF Sukhoi Su-30MKI had dodged and jammed 3-4 AMRAAMs during the dogfight. Saudi Arabia During the Yemeni War, Saudi Arabia extensively used F-15 and Typhoon aircraft together with Patriot batteries to intercept and down Yemeni drones and missiles. In November 2021, a possible Foreign Military Sales contract was notified to the US Congress regarding the provision to Saudi Arabia for a mix of 280 AIM-120C-7 and C-8 missiles and related support equipment and service that would be used on Saudi F-15 and Typhoon aircraft. The deal was required to replenish Saudi missiles stock, running low due to extensive use of AMRAAMs and Patriots against Yemeni missiles and drones. Spain On 7 August 2018, a Spanish Air Force Eurofighter Typhoon accidentally launched a missile in Estonia. There were no human casualties, but a ten-day search operation for the missile was unsuccessful. Effectiveness The kill probability (Pk) is determined by several factors, including aspect (head-on interception, side-on or tail-chase), altitude, the speed of the missile and the target, and how hard the target can turn. Typically, if the missile has sufficient energy during the terminal phase, which comes from being launched at close range to the target from an aircraft with an altitude and speed advantage, it will have a good chance of success. This chance drops as the missile is fired at longer ranges as it runs out of overtake speed at long ranges, and if the target can force the missile to turn it might bleed off enough speed that it can no longer chase the target. Operationally, the missile, which was designed for beyond visual range combat, has a Pk of 0.59. The targets included six MiG-29s, a MiG-25, a MiG-23, two Su-22s, a Galeb, and a US Army Blackhawk that was targeted by mistake. Operational features summary AMRAAM has an all-weather, beyond-visual-range (BVR) capability. It improves the aerial combat capabilities of US and allied aircraft to meet the threat of enemy air-to-air weapons as they existed in 1991. AMRAAM serves as a follow-on to the AIM-7 Sparrow missile series. The new missile is faster, smaller, and lighter, and has improved capabilities against low-altitude targets. It also incorporates a datalink to guide the missile to a point where its active radar turns on and makes terminal intercept of the target. An inertial reference unit and micro-computer system makes the missile less dependent upon the fire-control system of the aircraft. Once the missile closes in on the target, its active radar guides it to intercept. This feature, known as "fire-and-forget", frees the aircrew from the need to further provide guidance, enabling the aircrew to aim and fire several missiles simultaneously at multiple targets and break a radar lock after the missile seeker goes active and guide themselves to the targets. The missile also features the ability to "Home on Jamming," giving it the ability to switch over from active radar homing to passive homing – homing on jamming signals from the target aircraft. Software on board the missile allows it to detect if it is being jammed, and guide on its target using the proper guidance system. Guidance system overview Interception course stage AMRAAM uses two-stage guidance when fired at long range. The aircraft passes data to the missile just before launch, giving it information about the location of the target aircraft from the launch point, including its direction and speed. This information is generally obtained using the launching aircraft's radar, although it could come from an infrared search and track system, from another fighter aircraft via a data link, or from an AWACS aircraft. Using its built-in inertial navigation system (INS), the missile uses the information provided pre-launch to fly on an interception course toward the target. After launch, if the firing aircraft or surrogate continues to track the target, periodic updates, e.g. changes in the target's direction and speed, are sent from the launch aircraft to the missile, allowing the missile to adjust its course, via actuation of the rear fins, so that it is able to close to a self-homing distance where it will be close enough to "catch" the target aircraft in the basket (the missile's radar field of view in which it will be able to lock onto the target aircraft, unassisted by the launch aircraft). Not all armed services using the AMRAAM have elected to purchase the mid-course update option, which limits AMRAAM's effectiveness in some scenarios. The RAF initially opted not to use mid-course update for its Tornado F3 force, only to discover that without it, testing proved the AMRAAM was less effective in beyond visual range (BVR) engagements than the older semi-active radar homing BAE Skyflash (a development of the Sparrow), since the AIM-120's own radar is necessarily of lesser range and power as compared to that of the launch aircraft. Terminal stage and impact Once the missile closes to self-homing distance, it turns on its active radar seeker and searches for the target aircraft. If the target is in or near the expected location, the missile will find it and guide itself to the target from this point. If the missile is fired at short range, within visual range (WVR) or the near BVR, it can use its active seeker just after launch to guide it to intercept. Boresight Visual mode Apart from the radar-slaved mode, there is a free guidance mode, called "Visual". This mode is host-aircraft radar guidance-free—the missile just fires and locks onto the first thing it sees. This mode can be used for defensive shots, i.e. when the enemy has numerical superiority. Variants and upgrades Air-to-air missile versions There are currently four main variants of AMRAAM, all in service with the United States Air Force, United States Navy, and the United States Marine Corps. The AIM-120A is no longer in production and shares the enlarged wings and fins with the successor AIM-120B. The AIM-120C has smaller "clipped" aerosurfaces to enable internal carriage on the USAF F-22 Raptor. AIM-120B deliveries began in 1994. The AIM-120C deliveries began in 1996. The C-variant has been steadily upgraded since it was introduced. The AIM-120C-6 contained an improved fuze (Target Detection Device) compared to its predecessor. The AIM-120C-7 development began in 1998 and included improvements in homing and greater range (actual amount of improvement unspecified). It was successfully tested in 2003 and is currently being produced for both domestic and foreign customers. It helped the U.S. Navy replace the F-14 Tomcats with F/A-18E/F Super Hornets – the loss of the F-14's long-range AIM-54 Phoenix missiles (already retired) is offset with a longer-range AMRAAM-D. The lighter weight of the enhanced AMRAAM enables an F/A-18E/F pilot greater bring-back weight upon carrier landings. The AIM-120D is an upgraded version of the AMRAAM with improvements in almost all areas, including 50% greater range (than the already-extended range AIM-120C-7) and better guidance over its entire flight envelope yielding an improved kill probability (Pk). Initial production began in 2006 under the Engineering and Manufacturing Development phase of program testing and ceased in September of 2009. Raytheon began testing the D model on August 5, 2008, the company reported that an AIM-120D launched from an F/A-18F Super Hornet passed within lethal distance of a QF-4 target drone at the White Sands Missile Range. The range of the AIM-120D is classified, but is thought to extend to about . The AIM-120D (P3I Phase 4) is a development of the AIM-120C with a two-way data link, more accurate navigation using a GPS-enhanced IMU, an expanded no-escape envelope, improved HOBS (high off-boresight) capability, and a max speed of Mach 4. The AIM-120D is a joint USAF/USN project for which Follow-on Operational Test and Evaluation (FOT&E) was completed in 2014. The USN was scheduled to field it from 2014, and AIM-120D will be carried by all Pacific carrier groups by 2020, although the 2013 sequestration cuts could push back this later date to 2022. The Royal Australian Air Force requested 450 AIM-120D missiles, which would make it the first foreign operator of the missile. The procurement, approved by the US Government in April 2016, will cost $1.1 billion and will be integrated for use on the F/A-18F Super Hornet, EA-18G Growler and the F-35 Lightning II aircraft. There were also plans for Raytheon to develop a ramjet-powered derivative of the AMRAAM, the Future Medium Range Air-Air Missile (FMRAAM). The FMRAAM was not produced since the target market, the British Ministry of Defence, chose the Meteor missile over the FMRAAM for a BVR missile for the Eurofighter Typhoon aircraft. Raytheon is also working with the Missile Defense Agency to develop the Network Centric Airborne Defense Element (NCADE), an anti-ballistic missile derived from the AIM-120. This weapon will be equipped with a ramjet engine and an infrared homing seeker derived from the Sidewinder missile. In place of a proximity-fuzed warhead, the NCADE will use a kinetic energy hit-to-kill vehicle based on the one used in the Navy's RIM-161 Standard Missile 3. The -120A and -120B models are currently nearing the end of their service life while the -120D variant achieved initial operational capability in 2015. AMRAAM was due to be replaced by the USAF, the U.S. Navy, and the U.S. Marine Corps after 2020 by the Joint Dual Role Air Dominance Missile (Next Generation Missile), but it was terminated in the 2013 budget plan. Exploratory work was started in 2017 on a replacement called Long-Range Engagement Weapon. In 2017, work on the AIM-260 Joint Advanced Tactical Missile (JATM) began to create a longer-ranged replacement for the AMRAAM to contend with foreign weapons like the Chinese PL-15. Flight tests are planned to begin in 2021 and initial operational capability is slated for 2022, facilitating the end of AMRAAM production by 2026. In July 2022, Raytheon announced the AIM-120D-3 became the longest-range variant in testing, as well as an air-launched adaptation of the NASAMS-based AMRAAM-ER called the AMRAAM-AXE (air-launched extended envelope). The development of AIM-120D-3 and AMRAAM-AXE is likely driven by the PL-15 performance. The AIM-120D-3 and the AIM-120C-8 variant for international customers were developed under the Form, Fit, Function Refresh (F3R) program and feature 15 upgraded circuit cards in the missile guidance section and the capability to continuously upgrade future software enhancements. All AMRAAMs planned for production are either the AIM-120D-3 or the AIM-120C-8 incorporating F3R functionality as of April 2023. Ground-launched systems The Norwegian Advanced Surface-to-Air Missile System (NASAMS), developed by Kongsberg Defence & Aerospace and fielded in 1994-1995, consists of a number of towed batteries (containing six AMRAAM launching canisters with integrated launching rails) along with separate radar trucks and control station vehicles. The US Marine Corps and the US Army tested launching AMRAAM missiles from a six-rail carrier on HMMWV as part of their CLAWS (Complementary Low-Attitude Weapon System) and SLAMRAAM (Surface Launched AMRAAM) programs, which were canceled due to budgetary cuts. A more recent version is the High Mobility Launcher for the NASAMS, made in cooperation with Raytheon (Kongsberg Defence & Aerospace was already a subcontractor on the SLAMRAAM system), where the launch-vehicle is a Humvee (M1152A1 HMMWV), containing four AMRAAMs and two optional AIM-9X Sidewinder missiles. AMRAAM-ER As part of the SLAMRAAM project, Raytheon offered the Extended Range upgrade to surface-launched AMRAAM, called AMRAAM-ER. The missile is an Evolved Sea Sparrow Missile using AMRAAM head with two-stage guidance system. It was first shown at the Paris Air Show 2007 and was test-fired in 2008. Following the cancellation of SLAMRAAM funding in 2011, development of the NASAMS version restarted in 2014. in February 2015 Raytheon announced the AMRAAM-ER missile option for NASAMS, with expected production in 2019, and the first flight test took place in August 2016. Engagement envelope was expanded with a 50 percent increase in maximum range and 70 percent increase in maximum altitude. In 2019 Qatar placed an order for AMRAAM-ER missiles as part of a NASAMS purchase. The missile was testfired at Andøya Space Center in May 2021. Raytheon has proposed an air-launched adaptation of the missile called AMRAAM-AXE, from "Air-launched Extended Envelope". Foreign sales Canadair, now Bombardier, had largely helped with the development of the AIM-7 Sparrow and Sparrow II, and assisted to a lesser extent in the AIM-120 development. In 2003, the RCAF placed an order for 97 Aim-120C-5 and later C-7 missiles. These missiles have been in service on the CF-18 Hornet since 2004, and fully replaced the AIM-7 Sparrow in the 2010s. In 2020, the Canadian Government was approved by the U.S DoD for 32 advanced AIM-120D missiles to supplement the AIM-120C stockpile. The package included the 32 active AIM-120D-3 missiles, as well as 18 Captive Training Missiles, and a variety of training equipment and spare parts for $140M. Canada is one of a few countries currently authorized to purchase the longer range AIM-120D missile. In early 1995 South Korea ordered 88 AIM-120A missiles for its KF-16 fleet. In 1997 South Korea ordered 737 additional AIM-120B missiles. In 2006 Poland received AIM-120C-5 missiles to arm its new F-16C/D Block 52+ fighters. In 2017 Poland ordered AIM-120C-7 missiles. In early 2006, the Pakistan Air Force (PAF) ordered 500 AIM-120C-5 AMRAAM missiles as part of a $650 million F-16 ammunition deal to equip its F-16C/D Block 50/52+ and F-16A/B Block 15 MLU fighters. The PAF got the first three F-16C/D Block 50/52+ aircraft on July 3, 2010 and first batch of AMRAAMs on July 26, 2010. In 2007, the United States government agreed to sell 218 AIM-120C-7 missiles to Taiwan as part of a large arms sales package that also included 235 AGM-65G-2 Maverick missiles. Total value of the package, including launchers, maintenance, spare parts, support and training rounds, was estimated at around US$421 million. This supplemented an earlier Taiwanese purchase of 120 AIM-120C-5 missiles a few years ago. In 2008 there were announcements of new or additional sales to Singapore, Finland, Morocco and South Korea; in December 2010 the Swiss government requested 150 AIM-120C-7 missiles. Sales to Finland have stalled, because the manufacturer has not been able to fix a mysterious bug that causes the rocket motors of the missile to fail in cold tests. On May 5, 2015, the State Department has made a determination approving a possible Foreign Military Sale to Royal Malaysian Air Force for AIM-120C-7 AMRAAM missiles and associated equipment, parts and logistical support for an estimated cost of $21 million. In March 2016, the US government approved the sales of 36 units of AIM-120C-7 missiles to the Indonesian Air Force to equip their fleet of F-16 C/D Block 25. The AIM-120C-7 is also equipped for the upgraded F-16 A/B Block 15 OCU through Falcon Star-eMLU upgrade project. In March 2019, the US Department of State and Defense Security Cooperation Agency formally signed off on a US$240.5 million foreign military sale to support Australia’s introduction of the NASAMS and LAND 19 Phase 7B program. As part of the deal, the Australian government requested up to 108 Raytheon AIM-120C-7 AMRAAM, six AIM-120C-7 AMRAAM Air Vehicles Instrumented; and six spare AIM-120C-7 AMRAAM guidance sections. In December 2019, the United States Congress approved the sale of AIM-120C-7/C-8 to the Republic of Korea. According to the Federal Register document, the AIM-120C-8 is a refurbished version of AIM-120C-7, which replaced some discontinued parts with equivalent commercial parts and its capabilities are identical to AIM-120C-7. This was the first time the C-8 version of AMRAAM has appeared in the US arms sales contract. Later, Japan, the Netherlands, the UAE, Spain and Norway received approval to purchase AIM-120C-8s. In November 2021, Saudi Arabia received approval to purchase 280 AIM-120C-7/C-8s. Canada, United Kingdom, Australia and Norway have been approved to purchase the AIM-120D. Norway ordered 205 AIM-120D and 60 AIM-120D3 in November 2022.

AGM-88 HARM

The AGM-88 HARM (High-speed Anti-Radiation Missile) is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments. Description The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input. The proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. A smokeless, solid-propellant, booster-sustainer rocket motor propels the missile at speeds over Mach 2.0. The HARM was a missile program led by the U.S. Navy, and it was first carried by the A-6E, A-7, and F/A-18A/B aircraft, and then it equipped the EA-6B and EA-18G dedicated electronic attack aircraft. RDT&E for use on the F-14 aircraft was begun, but not completed. The U.S. Air Force (USAF) put the HARM onto the F-4G Wild Weasel aircraft, and later on specialized F-16s equipped with the HARM Targeting System (HTS). The missile has three operational modes: Pre-Briefed (PB), Target Of Opportunity (TOO) and Self-Protect (SP). The HTS pod, used by the USAF only, allows F-16s to detect and automatically target radar systems with HARMs instead of relying on the missile's sensors alone. History Deployment United States The HARM missile was approved for full production in March 1983, obtained initial operating capability (IOC) on the A-7E Corsair II in late 1983 and then deployed in late 1985 with VA-46 aboard the aircraft carrier USS America. In 1986, the first successful firing of the HARM from an EA-6B was performed by VAQ-131. It was soon used in combat—in March 1986 against a Libyan S-200 surface to air missiles site in the Gulf of Sidra, and then during Operation Eldorado Canyon in April. HARM was used extensively by the Navy, Marine Corps, and the Air Force in Operation Desert Storm during the Persian Gulf War of 1991. During the Gulf War, the HARM was involved in a friendly fire incident when the pilot of an F-4G Wild Weasel escorting a B-52G bomber mistook the latter's tail gun radar for an Iraqi AAA site — this was after the tail gunner of the B-52 had targeted the F-4G, mistaking it for an Iraqi MiG. The F-4 pilot launched the missile and then saw that the target was the B-52, which was hit. It survived with shrapnel damage to the tail and no casualties. The B-52 (serial number 58-0248) was subsequently renamed In HARM's Way. "Magnum" is spoken over the radio to announce the launch of an AGM-88. During the Gulf War, if an aircraft was illuminated by enemy radar a bogus "Magnum" call on the radio was often enough to convince the operators to power down. This technique would also be employed in Yugoslavia during air operations in 1999. On 28 April 1999, during this campaign, an early variant of the AGM-88, after being fired in self defense mode by a NATO jet, lost its radio frequency track as the Serbian air defense radar was turned off, hitting a house in the Gorna Banya district of the Bulgarian capital, Sofia, causing damages, but no casualties. During the 1990s and early 2000s and during the initial weeks of the operation Iraqi Freedom, the HARM was used to enforce the Iraqi No-Fly-Zones, degrading the Iraqi air defenses trying to engage US and allied patrolling aircraft. During the opening days of Operation Iraqi Freedom, deconflicting US Army Patriot batteries and allied aircraft routes turned out being more difficult than expected, resulting in three major friendly fire incidents: in one of them, on March 24, 2003, a USAF F-16CJ Fighting Falcon fired an AGM-88 HARM at a Patriot missile battery after the Patriot's radar had locked onto and prepared to fire at the aircraft, causing the pilot to mistake it for an Iraqi surface-to-air missile system because the aircraft was in air combat operations and was on its way to a mission near Baghdad. The HARM damaged the Patriot's radar system with no casualties. Starting in March 2011, during Operation Unified Protector against Libya, US Navy EA-18Gs had their combat debut using HARMs against Libyan air defenses together with USAF F-16CJs and Italian Tornadoes. Israel In 2013, US President Obama offered the AGM-88 to Israel for the first time. Italy Starting in March 2011, during Operation Unified Protector, Italian Tornadoes employed AGM-88 HARMs against Libyan air defenses. Ukraine In mid-2022, during the Russian invasion of Ukraine, the US supplied AGM-88 HARM missiles to Ukraine. It was only disclosed after Russian forces showed footage of a tail fin from one of these missiles in early August 2022. U.S. Under Secretary of Defense for Policy Colin Kahl said in recent aid packages they had included a number of anti-radiation missiles that can be fired by Ukrainian aircraft. As built, Soviet-era aircraft do not have the computer architecture to accept NATO standard weapons. Indeed, none of the former Warsaw Pact countries, even those that have had their Soviet-era aircraft updated, were enabled to fire a HARM before. The interface seemed difficult unless using a "crude modification", such as integrating it with an added e-tablet into the cockpit, building a nearly totally independent subsystem within the carrying aircraft. As suggested by Domenic Nicholis, defense correspondent for the Telegraph in the UK, the HARM missile is possibly operating in one of its three modes that enables it to find its target once flying after being released towards a possible enemy air defense and electronic emission area. Pre mission or during flight, NATO signals intelligence aircraft or different intelligence would be providing the overall electromagnetic emissions battlefield to locate the Russian radars where the Ukrainian jets, armed with HARMs would be directed to fire them. This allows the missile to achieve a very long range attack profile, even if it's possible that the missile does not find a target while flying, going wasted. A second possible use of the HARM is operating it in a mode called “HARM as sensor”. Similar to the described mode before, the missile acts as both sensor and weapon, not requiring a sensor pod. A simple interface would show that the missile has a target and the pilot can launch it. In this way the range is shorter, and the jet could be under threat already, but would maximize the possibility to hit the emitter. In August 2022, a senior U.S. defense official confirmed that the Ukrainians have successfully integrated the AGM-88 HARM missile onto their "MiG aircraft", hinting the MiG-29 was the chosen fighter jet with video evidence of AGM-88 missiles fired by upgraded Ukrainian MiG-29s released by the Ukrainian Air Force a few days later. Speaking on 19 September, US Air Force General James B. Hecker said the effort to integrate AGM-88 HARM missiles into the Ukrainian Su-27s and MiG-29s took "some months" to achieve. This does not give the Ukrainian air force the same "capabilities that it would on an F-16.” However he said: “Even though you don't get a kinetic kill ... you can get local air superiority for a period of time where you can do what you need to do.” During early September 2022, a Ukrainian Su-27S was spotted with an AGM-88 HARM fitted on the wing pylons. This is the first case of an Su-27 being spotted with an AGM-88 fitted. The missile has been directly fitted to the APU-470 missile launchers, the same launcher used by MiG-29 and Su-27 to fire missiles like the R-27 (air-to-air missile). This suggests that mounting the missile on Soviet aircraft is much easier than experts initially believed. Being as simple as "requiring just an interface for the different wirings and the hanging points of the missile". The earlier footage of a Ukrainian MiG-29 using an AGM-88 indicated that the display recognized the missile as a R-27EP, which is designed to lock onto airborne radars. This suggests that the aircraft are using their own avionics to fire the missile, without the need for additional modifications. In December, Ukrainian Air Force released a video showing a MiG-29 firing two HARM missiles in a volley. Russia has made the first claim of the war that they have shot down four HARM missiles. Variants AGM-88E AARGM A newer upgrade, the AGM-88E Advanced Antiradiation Guided Missile (AARGM), features the latest software, enhanced capabilities intended to counter enemy radar shutdown, and passive radar using an additional active millimeter-wave seeker. It was released in November 2010, and it is a joint venture by the US Department of Defense and the Italian Ministry of Defense, produced by Orbital ATK. In November 2005, the Italian Ministry of Defense and the U.S. Department of Defense signed a Memorandum of Agreement on the joint development of the AGM-88E AARGM missile. Italy was providing $20 million of developmental funding as well as several million dollars worth of material, equipment, and related services. The Italian Air Force was expected to buy up to 250 missiles for its Tornado ECR aircraft. A flight test program was set to integrate the AARGM onto Tornado ECR's weapon system. The U.S. Navy demonstrated the AARGM's capability during Initial Operational Test and Evaluation (IOT&E) in spring 2012 with live firing of 12 missiles. Aircrew and maintenance training with live missiles was completed in June. The Navy authorized Full-Rate Production (FRP) of the AARGM in August 2012, with 72 missiles for the Navy and nine for the Italian Air Force to be delivered in 2013. A U.S. Marine Corps F/A-18 Hornet squadron will be the first forward-deployed unit with the AGM-88E. In September 2013, ATK delivered the 100th AARGM to the U.S. Navy. The AGM-88E program is on schedule and on budget, with Full Operational Capability (FOC) planned for September 2014. The AGM-88E was designed to improve the effectiveness of legacy HARM variants against fixed and relocatable radar and communications sites, particularly those that would shut down to throw off anti-radiation missiles, by attaching a new seeker to the existing Mach 2-capable rocket motor and warhead section, adding a passive anti-radiation homing receiver, satellite and inertial navigation system, a millimeter-wave radar for terminal guidance, and the ability to beam up images of the target via a satellite link just seconds before impact. This model of the HARM will be integrated onto the F/A-18C/D/E/F, EA-18G, Tornado ECR aircraft, and later on the F-35 (externally). In September 2015, the AGM-88E successfully hit a mobile ship target in a live-fire test, demonstrating the missile's ability to use antiradiation homing and millimeter-wave radar to detect, identify, locate, and engage moving targets. In December 2019, the German Air Force ordered the AARGM. On August 4, 2020, Northrop Grumman's Alliant Techsystems Operations division, based in Northridge, California, was awarded a $12,190,753 IDIQ contract for AARGM depot sustainment support, guidance section and control section repair, and equipment box test and inspection. On August 31, 2020, the same Northrop Grumman division was allocated roughly $80.9 million to develop new technology for the AARGM. AGM-88F HCSM Although the US Navy/Marine Corps chose the Orbital ATK-produced AGM-88E AARGM, Raytheon developed its own update of the HARM called the AGM-88F HARM Control Section Modification (HCSM), tested in conjunction with and ultimately for the US Air Force. It incorporates similar upgrade features as the AARGM. The Republic of China (Taiwan), Bahrain, and Qatar have purchased AGM-88Bs which were then retrofitted with the HCSM upgrade. AGM-88G AARGM-ER The Navy's FY 2016 budget included funding for an extended range AARGM-ER that uses the existing guidance system and warhead of the AGM-88E with a solid integrated rocket-ramjet to double the range. In September 2016, Orbital ATK unveiled its extended-range AARGM-ER, which incorporates a redesigned control section and rocket motor for twice the range and internal carriage on the Lockheed Martin F-35A and F-35C Lightning II with integration on P-8 Poseidon, F-16 Fighting Falcon and Eurofighter Typhoon planned afterwards; internal carriage on the F-35B is not possible due to internal space limitations. The new missile utilizes the AARGM's warhead and guidance systems in a new airframe that replaces the mid-body wings with aerodynamic strakes along the sides with control surfaces relocated to low-drag tail surfaces and a more powerful propulsion system for greater speed and double the range of its predecessor. The U.S. Navy awarded Orbital ATK a contract for AARGM-ER development in January 2018. The USAF later joined the AARGM-ER program, involved in internal F-35A/C integration work. The AARGM-ER received Milestone-C approval in August 2021, and the first low-rate initial production contract was awarded the next month; initial operational capability is planned for 2023. The AARGM-ER completed its first, second, third, fourth and fifth flight tests at the Point Mugu Sea Range in July 2021, January 2022, July 2022, December 2022 and May 2023 respectively. In February 2023, the U.S. Navy began exploring the feasibility of launching the AARGM-ER from ground-based launchers and the P-8 Poseidon. On February 27, 2023, Australia has requested to purchase up to 63 AGM-88G AARGM-ERs. On June 5, 2023, The Netherlands announced the acquisition of the AARGM-ER for the use on their F-35A fleet. On October 23, 2023, Finland has been given permission by U.S. State Department to proceed with purchase of up to 150 AGM-88G AARGM-ERs. Stand-in Attack Weapon In May 2022, the USAF awarded contracts to L3Harris Technologies, Lockheed Martin, and Northrop Grumman to begin the first phase of development for the Stand-in Attack Weapon (SiAW), which will be the successor to the AARGM-ER. While previous HARMs were meant to attack air defense radars, the SiAW will have a broader target set including theater ballistic missile launchers, cruise and anti-ship missile launchers, GPS jamming platforms, and anti-satellite systems. It will have a shorter range than standoff weapons, being fired by an aircraft after penetrating enemy airspace. The SiAW will fit inside the F-35's internal weapon bays. The Air Force plans to have an operational weapon by 2026. Northrop Grumman was chosen to continue development of the SiAW in September 2023. Criticism During Operation Allied Force, NATO reportedly fired 743 HARMs during the course of the 78-day campaign, but could confirm the destruction of only 3 of the original 25 SA-6 batteries. Over half of the HARMs expended were preemptive targeting shots (PETs), fired at suspected SAM sites, but without a radar to target. During the campaign, Serbian SAM sites fired more than 800 SAMs with only 2 NATO aircraft downed, the majority from fixed sites were fired without radar guidance. Radars were also forced to operate for only 20 seconds or less to avoid destruction by HARMs. According to Benjamin Lambeth, the F-117 that was downed did not have SEAD support from HARM-carrying F-16CJ aircraft.

AGM-65 Maverick

The AGM-65 Maverick is an air-to-ground missile (AGM) designed for close air support. It is the most widely produced precision-guided missile in the Western world, and is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities. Development began in 1966 at Hughes Aircraft Company as the first missile to use an electronic contrast seeker. It entered service with the United States Air Force in August 1972. Since then, it has been exported to more than 30 countries and is certified on 25 aircraft. The Maverick served during the Vietnam, Yom Kippur, Iran–Iraq, and Persian Gulf Wars, along with other smaller conflicts, destroying enemy forces and installations with varying degrees of success. Since its introduction into service, numerous Maverick versions had been designed and produced using electro-optical, laser, and imaging infrared guidance systems. The AGM-65 has two types of warhead: one has a contact fuze in the nose, the other has a heavyweight warhead fitted with a delayed-action fuze, which penetrates the target with its kinetic energy before detonating. The missile is currently produced by Raytheon Missiles & Defense. The Maverick shares the same configuration as Hughes' AIM-4 Falcon and AIM-54 Phoenix, and measures more than in length and in diameter. Development The Maverick's development history began in 1965, when the United States Air Force (USAF) began a program to develop a replacement to the AGM-12 Bullpup. With a range of , the radio-guided Bullpup was introduced in 1959 and was considered a "silver bullet" by operators. However, the launch aircraft was required to fly straight towards the target during the missile's flight instead of performing evasive maneuvers, thus endangering itself. Even when it hit, the small warhead was only useful against small targets like bunkers; when used against larger targets like the Thanh Hóa Bridge it did little more than char the structure. The USAF began a series of projects to replace Bullpup, both larger versions of Bullpup, models C and D, as well as a series of Bullpup adaptations offering fire-and-forget guidance. Among the latter were the AGM-83 Bulldog, AGM-79 Blue Eye and AGM-80 Viper. From 1966 to 1968, Hughes Missile Systems Division and Rockwell competed for the contract to build an entirely new fire-and-forget missile with far greater range performance than any of the Bullpup versions. Each were allocated $3 million for preliminary design and engineering work of the Maverick in 1966. In 1968, Hughes emerged with the $95 million contract for further development and testing of the missile; at the same time, contract options called for 17,000 missiles to be procured. Hughes conducted a smooth development of the AGM-65 Maverick, with the first unguided test launch from an F-4 on 18 September 1969, with the first guided test on 18 December successfully performing a direct hit on a M41 tank target at the Air Force Missile Development Center at Holloman Air Force Base, New Mexico. In July 1971, the USAF and Hughes signed a $69.9 million contract for 2,000 missiles, the first of which was delivered in 1972. Although early operational results were favorable, military planners predicted that the Maverick would fare less successfully in the hazy conditions of Central Europe, where it would have been used against Warsaw Pact forces. As such, development of the AGM-65B "Scene Magnified" version began in 1975 before it was delivered during the late 1970s. When production of the AGM-65A/B was ended in 1978, more than 35,000 missiles had been built. More versions of the Maverick appeared, among which was the laser-guided AGM-65C/E. Development of the AGM-65C started in 1978 by Rockwell, who built a number of development missiles for the USAF. Due to high cost, the version was not procured by the USAF, and instead entered service with the United States Marine Corps (USMC) as the AGM-65E. Another major development was the AGM-65D, which employed an imaging infrared (IIR) seeker. By imaging on radiated heat, the IIR is all-weather operable as well as showing improved performance in acquiring and tracking the hot engines, such as in tanks and trucks, that were to be one of its major missions. The seekerhead mechanically scanned the scene over a nitrogen-cooled 4-by-4 pixel array using a series of mirrored facets machined into the inner surface of the ring-shaped main gyroscope. The five-year development period of the AGM-65D started in 1977 and ended with the first delivery to the USAF in October 1983. The version received initial operating capability in February 1986. The AGM-65F is a hybrid Maverick combining the AGM-65D's IIR seeker with the warhead and propulsion components of the AGM-65E. Deployed by the United States Navy (USN), the AGM-65F is optimized for maritime strike roles. The first AGM-65F launch from the P-3C took place in 1989, and in 1994, the USN awarded Unisys a contract to integrate the version with the P-3C. Meanwhile, Hughes produced the AGM-65G, which essentially has the same guidance system as the D, with some software modifications that track larger targets. In the mid-1990s to early 2000s, there were several ideas of enhancing the Maverick's potential. Among them was the stillborn plan to incorporate the Maverick millimeter wave active radar homing, which can determine the exact shape of a target. Another study called "Longhorn Project" was conducted by Hughes, and later Raytheon following the absorption of Hughes into Raytheon, looked into a Maverick version equipped with turbojet engines instead of rocket motors. The "Maverick ER", as it was dubbed, would have a "significant increase in range" compared to the Maverick's current range of . The proposal was abandoned, but if the Maverick ER had entered production, it would have replaced the AGM-119B Penguin carried on the MH-60R. The most modern versions of the Maverick are the AGM-65H/K, which were in production . The AGM-65H was developed by coupling the AGM-65B with a charge-coupled device (CCD) seeker optimized for desert operations and which has three times the range of the original TV-sensor; a parallel USN program aimed at rebuilding AGM-65Fs with newer CCD seekers resulted in the AGM-65J. The AGM-65K, meanwhile, was developed by replacing the AGM-65G's IR guidance system with an electro-optical television guidance system. Design The Maverick has a modular design, allowing for different combinations of the guidance package and warhead to be attached to the rocket motor to produce a different weapon. It has long-chord delta wings and a cylindrical body, reminiscent of the AIM-4 Falcon and the AIM-54 Phoenix. Different models of the AGM-65 have used electro-optical, laser, and imaging infrared guidance systems. The AGM-65 has two types of warhead: one has a contact fuze in the nose, the other has a heavyweight warhead fitted with a delayed-action fuze, which penetrates the target with its kinetic energy before detonating. The latter is most effective against large, hard targets. The propulsion system for both types is a solid-fuel rocket motor behind the warhead. The Maverick missile is unable to lock onto targets on its own; it has to be given input by the pilot or weapon systems officer after which it follows the path to the target autonomously. In an A-10 Thunderbolt II, for example, the video feed from the seeker head is relayed to a screen in the cockpit, where the pilot can check the locked target of the missile before launch. A crosshair on the heads-up display is shifted by the pilot to set the approximate target, where the missile will then automatically recognize and lock on to the target. Once the missile is launched, it requires no further assistance from the launch vehicle and tracks its target automatically. This fire-and-forget property is not shared by the E version that uses semi-active laser homing. Variants Maverick A is the basic model and uses an electro-optical television guidance system. No longer in U.S. service. Maverick B is similar to the A model, although the B model added optical zooming to lock onto small or distant targets. Maverick C was to be a laser-guided variant for the United States Marine Corps (USMC). It was canceled before production, however its requirement was later met by the Maverick E. Maverick D replaced the electro-optical guidance with an imaging infrared system which doubled the practical firing distance and allowed for its use at night and during bad weather. A reduced smoke rocket engine was also introduced in this model. It achieved its initial operation capability in 1983. Maverick E uses a laser designator guidance system optimized for fortified installations using a delayed fuse combined with a heavier penetrating blast-fragmentation warhead ( vs. in older models) that perforates a target with its kinetic energy before detonation. It achieved initial operating capability in 1985 and was used mainly by USMC aviation. Maverick F, designed specially for United States Navy, it uses a modified Maverick D infrared guidance system optimized for tracking ships fitted onto a Maverick-E body and warhead. Maverick G model essentially has the same guidance system as the D with some software modification that enables the pilot to track larger targets. The G model's major difference is its heavier penetrator warhead taken from the Maverick E, compared to the D model's shaped-charge warhead. It completed tests in 1988. Maverick H model is an AGM-65B/D missile upgraded with a new charge-coupled device (CCD) seeker better suited for the desert environment. Maverick J model is a Navy AGM-65F missile upgraded with the new CCD seeker. However, this conversion is not confirmed. Maverick K model is an AGM-65G upgraded with the CCD seeker; at least 1,200, but possibly up to 2,500 AGM-65G rounds are planned for conversion to AGM-65K standard. Maverick E2/L model incorporates a laser-guided seeker that allows for designation by the launch aircraft, another aircraft, or a ground source and can engage small, fast moving, and maneuvering targets on land and at sea. Deployment The Maverick was declared operational on 30 August 1972 with the F-4D/Es and A-7s initially cleared for the type; the missile made its combat debut four months later with the USAF in Operation Linebacker II, the last major USAF operation of the Vietnam War. During the Yom Kippur War in October 1973, the Israelis used Mavericks to destroy and disable enemy vehicles. Deployment of early versions of the Mavericks in these two wars were successful due to the favorable atmospheric conditions that suited the electro-optical TV seeker. Ninety-nine missiles were fired during the two wars, eighty-four of which were successful.. The Maverick was used for trials with the BGM-34A unmanned aerial vehicle in 1972–1973. Targeting could be carried out with a TV camera in the nose of the UAV or using the seeker of an AGM-45 Shrike anti-radar missile also carried by the UAV to locate the target for the Maverick's camera to lock on to. In June 1975, during a border confrontation, a formation of Iranian F-4E Phantoms destroyed a group of Iraqi tanks by firing 12 Mavericks at them. Five years later, during Operation Morvarid as part of the Iran–Iraq War, Iranian F-4s used Mavericks to sink three Osa II missile boats and four P-6 combat ships. Due to weapons embargoes, Iran had to equip its AH-1J SeaCobra helicopters with AGM-65 Maverick missiles and used them with some success in various operations such as Operation Fath ol-Mobin wherein Iranian AH-1Js fired 11 Mavericks. In August 1990, Iraq invaded Kuwait. In early 1991, the US-led Coalition executed Operation Desert Storm during which Mavericks played a crucial role in the ousting of Iraqi forces from Kuwait. Employed by F-15E Strike Eagles, F/A-18 Hornets, AV-8B Harriers, F-16 Fighting Falcons and A-10 Thunderbolt IIs, but used mainly by the last two, more than 5,000 Mavericks were used to attack armored targets. The most-used variant by the USAF was the IIR-guided AGM-65D. The reported hit rate by USAF Mavericks was 80–90%, while for the USMC it was 60%. The Maverick was used again in Iraq during the 2003 Iraq War, during which 918 were fired. The first time the Maverick was fired from a Lockheed P-3 Orion at a hostile vessel was when the USN and coalition units came to the aid of Libyan rebels to engage the Libyan Coast Guard vessel Vittoria in the port of Misrata, Libya, during the late evening of 28 March 2011. Vittoria was engaged and fired upon by a USN P-3C Maritime Patrol aircraft with AGM-65 Maverick missiles.

AIM-54 Phoenix

The AIM-54 Phoenix is an American radar-guided, long-range air-to-air missile (AAM), carried in clusters of up to six missiles on the Grumman F-14 Tomcat, its only operational launch platform. The Phoenix was the United States' only long-range air-to-air missile. The combination of Phoenix missile and the Tomcat's AN/AWG-9 guidance radar meant that it was the first aerial weapons system that could simultaneously engage multiple targets. Due to its active radar tracking, the brevity code "Fox Three" was used when firing the AIM-54. Both the missile and the aircraft were used by Iran and the United States Navy. In US service both are now retired, the AIM-54 Phoenix in 2004 and the F-14 in 2006. They were replaced by the shorter-range AIM-120 AMRAAM, employed on the F/A-18 Hornet and F/A-18E/F Super Hornet—in its AIM-120D version, the latest version of the AMRAAM just matches the Phoenix's maximum range. The AIM-54 has been used in 62 air-to-air strikes, all by Iran during the eight-year Iran–Iraq War. Following the retirement of the F-14 by the U.S. Navy, the weapon's only current operator is the Islamic Republic of Iran Air Force. Development Background Since 1951, the Navy faced the initial threat from the Tupolev Tu-4K 'Bull' carrying anti-ship missiles or nuclear bombs. Eventually, during the height of the Cold War, the threat would have expanded into regimental-size raids of Tu-16 Badger and Tu-22M Backfire bombers equipped with low-flying, long-range, high-speed, nuclear-armed cruise missiles and considerable electronic countermeasures (ECM) of various types. This combination was considered capable of saturating fleet defenses and threatening carrier groups. The Navy would require a long-range, long-endurance interceptor aircraft to defend carrier battle groups against this threat. The proposed Douglas F6D Missileer was intended to fulfill this mission and oppose the attack as far as possible from the fleet it was defending. The weapon needed for interceptor aircraft, the Bendix AAM-N-10 Eagle, was to be an air-to-air missile of unprecedented range when compared to contemporary AIM-7 Sparrow missiles. It would work together with Westinghouse AN/APQ-81 radar. The Missileer project was cancelled in December 1960. AIM-54 In the early 1960s, the U.S. Navy made the next interceptor attempt with the F-111B, and they needed a new missile design. At the same time, the USAF canceled the projects for their land-based high-speed interceptor aircraft, the North American XF-108 Rapier and the Lockheed YF-12, and left the capable AIM-47 Falcon missile at a quite advanced stage of development, but with no effective launch platform. The AIM-54 Phoenix, developed for the F-111B fleet air defense fighter, had an airframe with four cruciform fins that was a scaled-up version of the AIM-47. One characteristic of the Missileer ancestry was that the radar sent it mid-course corrections, which allowed the fire control system to "loft" the missile up over the target into thinner air where it had better range. The F-111B was canceled in 1968. Its weapons system, the AIM-54 working with the AWG-9 radar, migrated to the new U.S. Navy fighter project, the VFX, which would later become the F-14 Tomcat. The AIM-54 Phoenix was also considered by the Royal Air Force to be used on Avro Vulcan bomber planes as part of an air defence aircraft. This missileer conversion would have used 12 missiles onboard and an extensive modification to the Vulcan's radar. In 1977, development of a significantly improved Phoenix version, the AIM-54C, was developed to better counter projected threats from tactical anti-naval aircraft and cruise missiles, and its final upgrade included a re-programmable memory capability to keep pace with emerging ECM. Usage in comparison to other weapon systems The AIM-54/AWG-9 combination had multiple track (up to 24 targets) and multiple launch (up to six Phoenixes can be launched nearly simultaneously) capability; the large missile is equipped with a conventional warhead. On the F-14, four missiles can be carried under the fuselage tunnel attached to special aerodynamic pallets, plus two under glove stations. A full load of six Phoenix missiles and the unique launch rails weighs in at over , about twice the weight of Sparrows, putting it above the allowable bringback load (which also would include enough fuel for go-around attempts). As such, carrying six Phoenix missiles would necessitate the jettison of at least some of the Phoenix missiles if they were not used. The most common air superiority payload was a mix of two Phoenix, three Sparrow, and two Sidewinder missiles. Most other US aircraft relied on the smaller, semi-active medium-range AIM-7 Sparrow. Semi-active guidance meant the aircraft no longer had a search capability while supporting the launched Sparrow, reducing situational awareness. The Tomcat's radar could track up to 24 targets in track-while-scan mode, with the AWG-9 selecting up to six potential targets for the missiles. The pilot or radar intercept officer (RIO) could then launch the Phoenix missiles once parameters were met. The large tactical information display (TID) in the RIO's cockpit gave information to the aircrew (the pilot had the ability to monitor the RIO's display) and the radar could continually search and track multiple targets after Phoenix missiles were launched, thereby maintaining situational awareness of the battlespace. The Link 4 datalink allowed US Navy Tomcats to share information with the E-2C Hawkeye AEW aircraft. During Desert Shield in 1990, the Link 4A was introduced; this allowed the Tomcats to have a fighter-to-fighter datalink capability, further enhancing overall situational awareness. The F-14D entered service with JTIDS that brought the even better Link 16 datalink "picture" to the cockpit. Active guidance The Phoenix has several guidance modes and achieves its longest range by using mid-course updates from the F-14A/B AWG-9 radar (APG-71 radar in the F-14D) as it climbs to cruise between and at close to Mach 5. The Phoenix uses this high altitude to maximize its range by reducing atmospheric drag. At around from the target, the missile activates its own radar to provide terminal guidance. Minimum engagement range for the Phoenix is around ; at this range active homing would initiate upon launch. Service history U.S. combat experience On January 5, 1999, a pair of US F-14s fired two Phoenixes at Iraqi MiG-25s southeast of Baghdad. Both AIM-54s' rocket motors failed and neither missile hit its target. On September 9, 1999, another US F-14 launched an AIM-54 at an Iraqi MiG-23 that was heading south into the no-fly zone from Al Taqaddum air base west of Baghdad. The missile missed, eventually going into the ground after the Iraqi fighter reversed course and fled north. The AIM-54 Phoenix was retired from USN service on September 30, 2004. F-14 Tomcats were retired on September 22, 2006. They were replaced by shorter-range AIM-120 AMRAAMs, employed on the F/A-18E/F Super Hornet. Despite the much-vaunted capabilities, the Phoenix was rarely used in combat, with only two confirmed launches and no confirmed targets destroyed in US Navy service. The USAF F-15 Eagle had responsibility for overland combat air patrol duties in Operation Desert Storm in 1991, primarily because of the onboard F-15 IFF capabilities. The Tomcat did not have the requisite IFF capability mandated by the JFACC to satisfy the rules of engagement to utilize the Phoenix capability at beyond visual range. The AIM-54 was not adopted by any foreign nation besides Iran, or any other US armed service, and was not used on any aircraft other than the F-14. Iranian combat experience On January 7, 1974 as part of Project Persian King, the Imperial Iranian Air Force placed an order for 424 AIM-54As, later increasing it by 290 missiles that June. Of the initial order, 274 missiles and 10 training rounds were delivered for US$150 million, until the 1979 Revolution ended deliveries and left the remaining 150 missiles embargoed and the additional order of 290 cancelled. According to Tom Cooper and Farzad Bishop, during the Iran–Iraq War AIM-54s fired by IRIAF Tomcats achieved 78 victories against Iraqi MiG-21s, MiG-23s, MiG-25s, Tu-22s, Su-20/22s, Mirage F 1s, Super Étendards, and even two AM-39 Exocets and a C-601. This includes two occasions where one AIM-54 was responsible for the downing of two Iraqi aircraft, as well as an incident on January 7, 1981 where a Phoenix fired at a four-ship of MiG-23s downed three and damaged the fourth. The US refused to supply spare parts and maintenance after the 1979 Revolution, except for a brief period during the Iran–Contra affair. According to Cooper, the Islamic Republic of Iran Air Force kept its F-14 fighters and AIM-54 missiles in regular use during the entire Iran–Iraq War, though periodic lack of spares grounded large parts of the fleet at times. During late 1987, the stock of AIM-54 missiles was at its lowest, with fewer than 50 operational missiles available. The missiles needed fresh thermal batteries that could only be purchased from the US. Iran found a clandestine buyer that supplied it with batteries, which cost up to US$10,000 each. Iran received spares and parts for both the F-14s and AIM-54s from various sources during the Iran–Iraq War, and has received more spares after the conflict. Iran started a program to build spares for the planes and missiles, and although there are claims that it no longer relies on outside sources to keep its F-14s and AIM-54s operational, there is evidence that Iran continues to procure parts clandestinely. Both the F-14 Tomcat and the AIM-54 Phoenix missile continue in the service of the Islamic Republic of Iran Air Force. Iran claimed to be working on building an equivalent missile and in 2013 unveiled the Fakour-90, an upgraded and reverse-engineered version of the Phoenix. Variants Original model that became operational with the U.S. Navy in about 1974, and it was also exported to Iran before the Iran hostage crisis beginning in 1979. Also known as the 'Dry' missile. A version with simplified construction and no coolant conditioning. Did not enter series production. Developmental work started in January 1972. 7 X-AIM-54B missiles were created for testing, 6 of them by modifying pilot production IVE/PIP rounds. After two successful test firings, the 'Dry' missile effort was cancelled for being "not cost effective". The only improved model that was ever produced. It used digital electronics in the place of the analog electronics of the AIM-54A. This model had better abilities to shoot down low and high-altitude antiship missiles. This model took over from the AIM-54A beginning in 1986. /sealed round More capabilities in electronic counter-countermeasures. It did not require coolant during flight. The Missile was deployed from 1988 onwards. Because the AIM-54 ECCM/Sealed received no coolant, F-14s carrying this version of the missile could not exceed a specified airspeed. There were also test, evaluation, ground training, and captive air training versions of the missile; designated ATM-54, AEM-54, DATM-54A, and CATM-54. The flight versions had A and C versions. The DATM-54 was not made in a C version as there was no change in the ground handling characteristics. A 1970s proposal for a ship launched version of the Phoenix as an alternative/replacement for the Sea Sparrow point defense system. It would also have provided a medium-range SAM capability for smaller and/or non-Aegis equipped vessels (such as the CVV). The Sea Phoenix system would have included a modified shipborne version of the AN/AWG-9 radar. Hughes Aircraft touted the fact that 27 out of 29 major elements of the standard (airborne) AN/AWG-9 could be used in the shipborne version with little modification. Each system would have consisted of one AWG-9 radar, with associated controls and displays, and a fixed 12-cell launcher for the Phoenix missiles. In the case of an aircraft carrier, for example, at least three systems would have been fitted in order to give overlapping coverage throughout the full 360°. Both land and ship based tests of modified Phoenix (AIM-54A) missiles and a containerised AWG-9 (originally the 14th example off the AN/AWG-9 production line) were successfully carried out from 1974 onwards. AIM-54B A land based version for the USMC was also proposed. It has been suggested that the AIM-54B would have been used in operational Sea Phoenix systems, although that version had been cancelled by the second half of the 1970s. Ultimately, a mix of budgetary and political issues meant that, despite being technically and operationally attractive, further development of the Sea Phoenix did not proceed. In February 2013 Iran reportedly tested an indigenous long-range air-to-air missile. In September 2013 it displayed the Fakour-90 on a military parade. It looked almost identical to the AIM-54 Phoenix. In July 2018 as reported by Jane's, Iran started mass production of the Fakour-90.

Lockheed AC-130

The Lockheed AC-130 gunship is a heavily armed, long-endurance, ground-attack variant of the C-130 Hercules transport, fixed-wing aircraft. It carries a wide array of ground-attack weapons that are integrated with sophisticated sensors, navigation, and fire-control systems. Unlike other modern military fixed-wing aircraft, the AC-130 relies on visual targeting. Because its large profile and low operating altitudes around 7,000 feet (2,100 m) make it an easy target, its close air support missions are usually flown at night. The airframe is manufactured by Lockheed Martin, while Boeing is responsible for the conversion into a gunship and for aircraft support. Developed during the Vietnam War as "Project Gunship II", the AC-130 replaced the Douglas AC-47 Spooky, or "Gunship I". The sole operator is the United States Air Force, which uses the AC-130U Spooky and AC-130W Stinger II variants for close air support, air interdiction, and force protection, with the upgraded AC-130J Ghostrider entering service. Close air support roles include supporting ground troops, escorting convoys, and urban operations. Air-interdiction missions are conducted against planned targets and targets of opportunity. Force-protection missions include defending air bases and other facilities. AC-130Us are based at Hurlburt Field, Florida, while AC-130Ws are based at Cannon AFB, New Mexico; gunships can be deployed worldwide. The squadrons are part of the Air Force Special Operations Command (AFSOC), a component of the United States Special Operations Command. The AC-130 has an unpressurized cabin, with the weaponry mounted to fire from the port side of the fuselage. During an attack, the gunship performs a pylon turn, flying in a large circle around the target, so is able to fire at it for far longer than in a conventional strafing attack. The AC-130H Spectre was armed with two M61 Vulcan cannons, one L/60 Bofors 40 mm cannon, and M137 cannon and M37 recoil mechanism from the M102 howitzer; after 1994, the cannons were removed. The upgraded AC-130U Spooky has a GAU-12 Equalizer cannon in place of the Spectre's two cannons, an improved fire-control system, and increased ammunition capacity. The new AC-130J was based on the MC-130J Commando II special-operations tanker. The AC-130W Stinger II is a modified C-130H with upgrades including a precision strike package. Development Origins During the Vietnam War, the C-130 Hercules was selected to replace the Douglas AC-47 Spooky gunship (Project Gunship I) to improve mission endurance and increase capacity to carry munitions. Capable of flying faster than helicopters and at high altitudes with excellent loiter time, the use of the pylon turn allowed the AC-47 to deliver continuous, accurate fire to a single point on the ground. In 1967, JC-130A 54-1626 was selected for conversion into the prototype AC-130A gunship (Project Gunship II). The modifications were done at Wright-Patterson Air Force Base by the Aeronautical Systems Division. A direct-view night-vision telescope was installed in the forward door, an early forward-looking infrared device was placed in the forward part of the left wheel well, with miniguns and rotary cannons fixed facing down and aft along the left side. The analog fire-control computer prototype was handcrafted by RAF Wing Commander Tom Pinkerton at the USAF Avionics Laboratory at Wright-Patterson AFB. Flight testing of the prototype was performed primarily at Eglin Air Force Base, followed by further testing and modifications. By September 1967, the aircraft was certified ready for combat testing and was flown to Nha Trang Air Base, South Vietnam, for a 90-day test program. The AC-130 was later supplemented by the AC-119 Shadow (Project Gunship III), which later proved to be underpowered. Seven more warplanes were converted to the "Plain Jane" configuration like the AC-130 prototype in 1968, and one aircraft received the "Surprise Package" refit in 1969. The Surprise Package upgrade included the latest 20 mm rotary autocannons and 40 mm Bofors cannon, but no 7.62 mm close-support armament. The Surprise Package configuration served as a test bed for the avionic systems and armament for the AC-130E. In 1970, 10 more AC-130As were acquired under the "Pave Pronto" project. In the summer of 1971, Surprise Package AC-130s were converted to the Pave Pronto configuration and assumed the new nickname of "Thor". Conversion of C-130Es into AC-130Es for the "PAVE Spectre" project followed. Regardless of their project names, the aircraft were more commonly referred to by the squadron's call sign, Spectre. Recent and planned upgrades In 2007, AFSOC initiated a program to upgrade the armament of AC-130s. The test program planned for the 25 mm GAU-12/U and 40 mm Bofors cannon on the AC-130U gunships to be replaced with two 30 mm Mk 44 Bushmaster II cannons. In 2007, the Air Force modified four AC-130U gunships as test platforms for the Bushmasters. These were referred to as AC-130U Plus 4 or AC-130U+4. AFSOC, however, canceled its plans to install the new cannons on its fleet of AC-130Us. It has since removed the guns and reinstalled the original 40 mm and 25 mm cannons and returned the planes to combat duty. Brigadier General Bradley A. Heithold, AFSOC's director of plans, programs, requirements, and assessments, said on 11 August 2008 that the effort was canceled because of problems with the Bushmaster's accuracy in tests "at the altitude we were employing it". Also, schedule considerations drove the decision, he said. Plans were made for possible replacement of the 105 mm cannon with a breech-loading 120 mm M120 mortar, and to give the AC-130 a standoff capability using either the AGM-114 Hellfire missile, the Advanced Precision Kill Weapon System (based on the Hydra 70 rocket), or the Viper Strike glide bomb. In 2010, the Air Force awarded L-3 Communications a $61 million (~$ in ) contract to add precision strike packages to eight MC-130W Combat Spear special-mission aircraft to give them a gunship-like attack capability; such-equipped MC-130Ws are known as Dragon Spears. AFSOC is arming these aircraft to relieve the high operational demands on AC-130 gunships until new AC-130Js enter service. The MC-130W Dragon Spear was renamed AC-130W Stinger II in 2011. The precision strike packages consist of a 30 mm gun and several precision guided munitions. Rails are mounted on the outboard pylon of the wing for four Hellfire missiles, SDBs, or SDB IIs under each. Ten common launch tubes (CLTs) are mounted on the rear ramp to fire Griffin A missiles; additional missiles are stored in the aircraft that can be reloaded in flight. CLTs are able to fire other small munitions able to fit inside the -diameter, -long tubes. The AC-130J Ghostrider came from a 2011 initiative that sought to acquire 16 new gunships based on newly built MC-130J Combat Shadow II special-operations tankers outfitted with a "precision strike package" to give them an attack capability, requesting $1.6 billion from fiscal years 2011 through 2015. This was to increase the size of the gunship fleet to 33 aircraft, a net increase of eight after the planned retirement of eight aging AC-130Hs. The first aircraft would be bought in fiscal 2012, followed by two in fiscal 2013, five in fiscal 2014, and the final eight in fiscal 2015. The decision to retain the C-130 came after funding for 16 C-27Js was removed from the fiscal 2010 budget. The AC-130J was to follow the path of the Dragon Spear program. On 9 January 2013, the Air Force began converting the first MC-130J Combat Shadow II into an AC-130J. The first AC-130J was delivered to AFSOC on 29 July 2015. The first AC-130J gunships achieved initial operational capability (IOC) on 30 September 2017. The AC-130J has two planned increments: the Block 10 configuration includes an internal 30 mm gun, small diameter bombs, and laser-guided missiles launched from the rear cargo door; and Block 20 configuration adds a 105 mm cannon, large aircraft infrared countermeasures, wing-mounted Hellfire missiles, and radio-frequency countermeasures. The Air Force decided to add a 105 mm cannon to the AC-130J in addition to the 30 mm cannon and smart bombs, the shells being more accurate and cheaper than dropping SDBs. AFSOC is actively pursuing a directed-energy weapon on board the AC-130J in place of the 30 mm gun by 2022, similar to the previous Advanced Tactical Laser program. It is to produce a beam of up to 120 kW, or potentially even 180–200 kW, weigh about , defensively destroy antiaircraft missiles, and offensively engage communications towers, boats, cars, and aircraft. However, laser armament may only be installed on a few aircraft rather than the entire AC-130J fleet; the laser will be mounted on the side in place of the 30 mm cannon. Other potential additions include an active denial system to perform airborne crowd control, and small unmanned aerial vehicles from the CLTs to provide remote video feed and coordinates to weapons operators through cloud cover. Called the Tactical Off-board Sensor (TOBS), the drones would be expendable and fly along a programmed orbit to verify targets the aircraft cannot see itself because of bad weather or standing off from air defenses. AFSOC was to initially use the Raytheon Coyote small UAV for the TOBS mission, as it is an off-the-shelf design with a one-hour endurance, but plans to fulfill the role with a new drone capable of a four-hour endurance by 2019. The Air Force was also interested in acquiring a glide bomb that can be launched from the CLTs, capable of hitting ground vehicles traveling as fast as 120 km/h (70 mph) while above . In June 2016, Dynetics was awarded a contract by SOCOM to integrate its tactical munition onto the AC-130. Designated the GBU-69/B Small Glide Munition, the weapon weighs and is armed with a blast-fragmentation warhead that can detonate by direct impact or at a selected height; despite being smaller, being unpowered allows for its warhead to be heavier than those on the Hellfire and Griffin A missiles, and , respectively. Guidance is provided by a GPS receiver with antispoofing software and four distributed-aperture semiactive laser seeker apertures adapted from the WGU-59/B APKWS for terminal guidance. Approval for fielding occurred in early 2017. Dynetics was awarded a contract to deliver an initial batch of 70 SGMs in June 2017, with plans to buy up to 1,000. The SGM can travel . Future , AC-130 gunships have been providing close air support for special operators for 56 years. Although the aircraft have been kept relevant through constant upgrades to their weaponry, sensor packages, and countermeasures, they are not expected to be survivable in future nonpermissive environments due to their high signatures and low airspeeds. Military analysts, such as the Center for Strategic and Budgetary Assessments, have suggested that AFSOC invest in more advanced technologies to fill the role to operate in future contested combat zones, including a mix of low-cost disposable unmanned and stealthy strike aircraft. Design Overview The AC-130 is a heavily armed, long-endurance aircraft carrying an array of weapons against ground targets that are integrated with sophisticated sensors, navigation, and fire-control systems. It is capable of delivering precision firepower or area-saturation fire over a target area over a long period of time, at night, or in adverse weather. The sensor suite consists of an electro-optical image sensor, infrared sensor, and radar. These sensors allow the gunship to visually or electronically identify friendly ground forces and targets in most weather conditions. The AC-130U is equipped with the AN/APQ-180, a synthetic aperture radar, for long-range target detection and identification. The gunship's navigational devices include inertial navigation systems and a global positioning system. The AC-130U employs technologies developed in the 1990s, which allow it to attack two targets simultaneously. It has twice the munitions capacity of the AC-130H. Although the AC-130U conducts some operations in daylight, most of its combat missions are conducted at night. The AC-130H's unit cost is US$132.4 million, and the AC-130U's cost is $190 million (fiscal 2001 dollars). Upgrades During the Vietnam War era, the various AC-130 versions following the Pave Pronto modifications were equipped with a magnetic anomaly detector system called Black Crow (designated AN/ASD-5), a highly sensitive passive device with a phased-array antenna located in the left-front nose radome that could pick up localized deviations in the Earth's magnetic field normally used to detect submerged submarines. The Black Crow system was slaved into the targeting computers of the AC-130A/E/H, enabling the detection of the unshielded ignition coils of North Vietnamese trucks hidden under dense jungle foliage along the Ho Chi Minh Trail. It could also detect hand-held transmitter signals of air controllers on the ground to identify and locate targets. The PGM-38/U enhanced 25 mm high-explosive incendiary round was created to expand the AC-130U gunships' mission in standoff range and survivability for its 25 mm GAU-12/U gun. This round is a combination of the existing PGU-25 HEI and a M758 fuze designated as FMU-151/B to meet the MIL-STD-1316. The FMU-151 has an improved arming delay with multisensitive range. Operational history Vietnam War The AC-130 gunship first arrived in South Vietnam on 21 September 1967 under the Gunship II program and began combat operations over Laos and South Vietnam that same year. In June 1968, AC-130s were deployed to Tan Son Nhut AB near Saigon for support against the Tet Offensive. By 30 October 1968, enough AC-130 Gunship IIs arrived to form a squadron, the 16th Special Operations Squadron of the 8th Tactical Fighter Wing, at Ubon Royal Thai Air Force Base, Thailand. At this time, the C-130A gunship was designated the AC-130A. On 18 August 1968, an AC-130 gunship flying an armed reconnaissance mission in Vietnam's III Corps was diverted to support the Katum Special Forces Camp. The ground commander quickly assessed the accurate fire and capabilities of this weapons system and called for fire on his own perimeter when the Viet Cong attempted to bridge the wire on the west side of his position. By December 1968, most AC-130s flew under F-4 Phantom II escort (to protect the gunship against heavy and concentrated antiaircraft fire) from the 497th Tactical Fighter Squadron, normally three Phantoms per gunship. On 24 May 1969, the first Spectre gunship was lost to enemy fire. In late 1969, under code name "Surprise Package", 56-0490 arrived with solid-state, laser-illuminated, low light-level TV with a companion YAG laser designator, an improved forward-looking infrared (FLIR) sensor, video recording for TV and FLIR, an inertial navigation system, and a prototype digital fire-control computer. The remaining AC-130s were refitted with upgraded similar equipment in the summer of 1970, and then redeployed to Ubon RTAFB. On 25 October 1971, the first "Cadillac" gunship, the AC-130E, arrived in Vietnam. On 17 February 1972, the first 105 mm cannon arrived for service with Spectre and was installed on Gunship 570. It was used from mid-February until the aircraft received battle damage to its right flap. The cannon was switched to Gunship 571 and was used until 30 March when the aircraft was shot down. On 28 January 1973, the Vietnam peace accord went into effect, marking the end of Spectre operations in Vietnam. Spectre was still needed and active in the region, supporting operations in Laos and Cambodia. On 22 February 1973, American offensive operations in Laos ended and the gunships became totally committed to operations in the Cambodian conflict. On 12 April 1975, the Khmer Rouge was threatening the capital of Phnom Penh and AC-130s were called on to help in Operation Eagle Pull, the final evacuation of American and allied officials from Phnom Penh before it was conquered by the communists. The AC-130 was also over Saigon on 30 April 1975 to protect the final evacuation in Operation Frequent Wind. Spectres were also called in when the USS Mayaguez was seized, on the open sea, by Khmer Rouge soldiers and sailors on 15 May 1975. Six AC-130s and 52 air crew members were lost during the war. AC-130s reportedly destroyed more than 10,000 trucks and participated in many crucial close-air-support missions in Vietnam. Cold War and later action With the conclusion of hostilities in Southeast Asia in the mid-1970s, the AC-130H became the sole gunship in the regular Air Force, home based at Hurlburt Field, Florida, while the AC-130A fleet was transferred to the Air Force Reserve's 919th Tactical Airlift Group (919 TAG) at Eglin AFB Auxiliary Field #3/Duke Field, Florida. With the transition to the AC-130A, the 919 TAG was then redesignated as the 919th Special Operations Group. In the late 1970s, when the AC-130H fleet was first being modified for in-flight refueling capability, a demonstration mission was planned and flown from Hurlburt Field, Florida, nonstop, to conduct a 2-hour live-fire mission over Empire Firing Range in the Republic of Panama, then return home. This 13-hour mission with two in-flight refuelings from KC-135 tankers proved the validity of flying long-range missions outside the contiguous United States to attack targets then return to home base without intermediate stops. AC-130s from both the 4th and 16th Special Operations Squadrons have been deployed in nearly every conflict in which the United States has been involved, officially and unofficially, since the end of the Vietnam War. In July 1979, AC-130H crews deployed to Howard Air Force Base, Panama, as a precaution against possible hostile actions against American personnel during the Nicaraguan Revolution. New time aloft and nonstop distance records were subsequently set by a 16th SOS two-ship AC-130H formation flight that departed Hurlburt Field on 13 November 1979 and landed on 15 November at Andersen Air Force Base, Guam, a distance of and 29 hours 43 minutes nonstop, refueling four times in-flight. Refueling support for the Guam deployment was provided by KC-135 crews from the 305th Air Refueling Wing from Grissom AFB, Indiana. In November 1979, four AC-130H gunships flew nonstop from Hurlburt Field to Anderson AFB, Guam, because of the hostage situation at the US Embassy in Iran. On Guam, AC-130H crews developed communications-out/lights-out refueling procedures for later employment by trial-and-error. This deployment with the 1 SOW/CC as task force commander was directed from the office of the CJCS for fear that Iranian militants could begin executing American Embassy personnel who had been taken hostage on 4 November. One early option considered AC-130H retaliatory punitive strikes deep within Iran. Later gunship flights exceeded the 1979 Hurlburt-to-Guam flight. Upon return in March 1980, the four planes soon found themselves in Egypt to support the ill-fated hostage rescue attempt. During Operation Urgent Fury in Grenada in 1983, AC-130s suppressed enemy air-defense systems and attacked ground forces enabling the assault of the Point Salines Airfield via airdrop and air-land of friendly forces. The AC-130 aircrew earned the Lieutenant General William H. Tunner Award for the mission. The AC-130Hs of the 16th Special Operations Squadron unit maintained an ongoing rotation to Howard AB, Panama, monitoring activities in El Salvador and other Central American points of interest, with rules of engagement eventually permitting attacks on FMLN targets. This commitment of maintainers and crews started in 1983 and lasted until 1990. The AC-130 is considered to have hastened the end of the Salvadoran Civil War in the 1980s. Crews flew undercover missions from Honduras and attacked guerrilla camps and concentrations. AC-130s also had a primary role during the United States invasion of Panama (named Operation Just Cause) in 1989, when they destroyed Panama Defense Force headquarters and numerous command-and-control facilities, and provided close air support for US ground troops. Aircrews earned the Mackay Trophy for the most meritorious flight of the year, and the Tunner Award. Gulf War and the 1990s During the Gulf War of 1990–1991 (Operations Desert Shield and Desert Storm), Regular Air Force and Air Force Reserve AC-130s provided close air support and force protection (air base defense) for ground forces, and battlefield interdiction. The primary interdiction targets were early-warning/ground-control intercept sites along the southern border of Iraq. At its standard altitude of , the aircraft had a proven ability to engage moving ground targets. The first gunship to enter the Battle of Khafji helped stop a southbound Iraqi armored column on 29 January 1991. One day later, three more gunships provided further aid to Marines participating in the operation. The gunships attacked Iraqi positions and columns moving south to reinforce their positions north of the city. Despite the threat of SAMs and increasing visibility during the early morning hours of 31 January 1991, one AC-130H, AF Serial No. 69-6567, call-sign Spirit 03, opted to stay to continue to protect the Marines. A lone Iraqi with a Strela-2 MANPADS shot Spirit 03 down, and all 14 crew members were killed. The loss of Spirit 03 did however result in the US DoD joining the development of the AN/AAQ-24 Directed Infrared Countermeasures System which, in its updated laser-based form, is now a common fit across large US military aircraft. The military has used AC-130 gunships during the humanitarian operations in Somalia (Operation Restore Hope and Operation United Shield) in 1992–93 and Operation Uphold Democracy in Haiti in 1994. AC-130s took part in Operation Assured Response in Liberia in 1996 and in Operation Silver Wake in 1997, the evacuation of American non-combatants from Albania. AC-130s took part in the NATO missions in Bosnia and Herzegovina and Kosovo during the 1990s. The AC-130U gunship set a new record for the longest sustained flight by any C-130 on 22 and 23 October 1997, when two AC-130U gunships flew 36 hours nonstop from Hurlburt Field to Taegu Air Base (Daegu), South Korea, being refueled seven times in the air by KC-135 tankers. The two gunships took on 410,000 lb (186,000 kg) of fuel. Gunships also were part of the buildup of US forces in 1998 to compel Iraq to allow UNSCOM weapons inspections. War on Terror The US has used gunships with deployments to the War in Afghanistan (Operation Enduring Freedom, Operation Freedom's Sentinel) (2001–2021), and Iraq War (Operation Iraqi Freedom) (2003–2011). AC-130 strikes were directed by special forces on known Taliban locations during the early days of the war in Afghanistan. US Special Operations Forces used the AC-130 to support its operations. The day after arriving in Afghanistan, the AC-130s attacked Taliban and Al-Qaeda forces near the city of Konduz and were directly responsible for the city's surrender the next day. On 26 November 2001, Spectres were called in to put down a rebellion at the prison fort of Qala-I-Janghi. The 16 SOS flew missions over Mazar-i-Sharif, Kunduz, Kandahar, Shkin, Asadabad, Bagram, Baghran, Tora Bora, and virtually every other part of Afghanistan. The Spectre participated in countless operations within Afghanistan, performing on-call close air support and armed reconnaissance. In March 2002, three AC-130 Spectres provided 39 crucial combat missions in support of Operation Anaconda in Afghanistan. During the intense fighting, the planes fired more than 1,300 40 mm and 1,200 105 mm rounds. Close air support was the main mission of the AC-130 in Iraq. Night after night, at least one AC-130 was in the air to fulfill one or more air-support requests (ASRs). A typical mission had the AC–130 supporting a single brigade's ASRs followed by aerial refueling and another two hours with another brigade or SOF team. The use of AC-130s in places like Fallujah, urban settings where insurgents were among crowded populations of non-combatants, was criticized by human rights groups. AC-130s were also used for intelligence gathering with their sophisticated long-range video, infrared and radar sensors. In 2007, US Special Operations forces also used the AC-130 in attacks on suspected Al-Qaeda militants in Somalia. Eight AC-130H and 17 AC-130U aircraft were in active-duty service as of July 2010. In March 2011, the Air Force deployed two AC-130U gunships to take part in Operation Odyssey Dawn, the US military intervention in Libya, which eventually came under NATO as Operation Unified Protector. By September 2013, 14 MC-130W Dragon Spear aircraft have been converted to AC-130W Stinger II gunships. The Stinger gunships have been deployed to Afghanistan to replace the aging AC-130H aircraft and provide an example for the new AC-130J Ghostrider. Modifications began by cutting holes in the plane to make room for weapons and adding kits and bomb bases for laser-guided munitions. Crews added a 105 mm cannon, 20-inch infrared and electro-optical sensors, and the ability to carry 250-lb bombs on the wings. The final AC-130H Spectre gunship, tail number 69-6569 "Excalibur" was retired on 26 May 2015 at Cannon Air Force Base, New Mexico. On 15 November 2015, two days after the attacks in Paris by ISIL, AC-130s and A-10 Thunderbolt II attack aircraft destroyed a convoy of over 100 ISIL-operated oil tanker trucks in Syria. The attacks were part of an intensification of the US-led military intervention against ISIL called Operation Tidal Wave II (named after the original Operation Tidal Wave during World War II, a failed attempt to raid German oil fields that resulted in heavy aircraft and aircrew loss) in an attempt to cut off oil smuggling as a source of funding for the group. On 3 October 2015, an AC-130 mistakenly attacked the Doctors Without Borders hospital in Kunduz, Afghanistan, killing 42 people and injuring over 30. In five separate runs, the gunship struck the hospital, that was erroneously identified as the source of attacks on coalition members. Subsequent inquiries led to punishment of 16 military personnel and cited "human error" as the root cause. On 30 September 2017, the Air Force declared the AC-130J Ghostrider had achieved initial operational capability, with six gunships having been delivered; the aircraft is planned to reach full operational capability by 2023 with 37 gunships delivered. The J-variant is lighter and more fuel efficient than previous versions, able to fly at with a range of and service ceiling of . The AC-130U returned from its final combat deployment on 8 July 2019; the final AC-130U was retired in June 2020. AFSOC started taking delivery of the AC-130J in spring 2019, and the aircraft began deploying to Afghanistan by the summer. Variants In service AC-130J Ghostrider Based on MC-130J; 32 aircraft were procured as of 2014 to replace the AC-130H. As of 2018, the first AC-130J Ghostrider squadron, the 73rd Special Operations Squadron, is operating from Hurlburt Field, Florida. Retired AC-130A Spectre (Project Gunship II, Surprise Package, Pave Pronto) Conversions of C-130As; 19 completed; transferred to Air Force Reserve in 1975, retired in 1995.

This aircraft was a conversion of the first production C-130. On 25 March 1971, it took an anti-aircraft artillery hit in the belly just aft of the nose gear wheel well over the Ho Chi Minh trail in Laos. The 37 mm shell destroyed everything below the crew deck and barely missed striking two crew members. The pilot was able to crash land the aircraft safely. In 1975, after the conclusion of US involvement in the Vietnam war, it was transferred to the Air Force Reserve, where it served with the 711th Special Operations Squadron of the 919th Special Operations Wing. In 1980, the aircraft was upgraded from the original three-bladed propellers to the quieter four-bladed propellers and was eventually retired in late 1995. The retirement also marked an end to the Air Force Reserve Command flying the AC-130A. The aircraft now sits on display in the final Air Force Reserve Command configuration with grey paint, black markings, and the four-bladed Hamilton Sunstrand 54H60-91 props at the Air Force Armament Museum at Eglin Air Force Base, Florida, USA. A second aircraft, AF serial no. 56–0509, named the Ultimate End, was originally accepted as a C-130A by the Air Force on 28 February 1957, and modified to the AC-130A configuration on 27 July 1970. The aircraft participated in the Vietnam War and the rescue of the SS Mayaguez. Ultimate End demonstrated the durability of the C-130 after surviving hits in five places by 37 mm anti-aircraft artillery on 12 December 1970, extensive left wing leading edge damage on 12 April 1971 and a 57 mm round damaging the belly and injuring one crewman on 4 March 1972. "Ultimate End" was reassigned to the Air Force Reserve's 919th Special Operations Wing at Eglin AFB Auxiliary Field No.3 / Duke Field on 17 June 1975, where it continued in service until retired in the fall 1994 and transferred to Air Force Special Operations Command's Heritage Air Park at Hurlburt Field, Florida. While assigned to the 711th Special Operations Squadron, Ultimate End served in Operations JUST CAUSE in Panama, DESERT STORM in Kuwait and Iraq, and UPHOLD DEMOCRACY in Haiti. After 36 years and seven months of service, 24 years as a gunship, Ultimate End retired from service on 1 October 1994. It made its last flight from Duke Field to Hurlburt Field on 20 October 1994. The Spectre Association dedicated "Ultimate End" (which served with the 16 SOS in Vietnam) on 4 May 1995. Lt Col Michael Byers, then 16 SOS commander, represented the active-duty gunship force and Clyde Gowdy of the Spectre Association represented all Spectre personnel past and present for the unveiling of a monument at the aircraft and the dedication as a whole. A third AC-130A, AF serial no. 54–1630, is on display in the Cold War Gallery at the National Museum of the United States Air Force at Wright-Patterson AFB, Ohio. Named Azrael for the angel of death in Islam who severs the soul from the body, this aircraft figured prominently in the closing hours of Operation Desert Storm. On 26 February 1991, Coalition ground forces were driving the Iraqi Army out of Kuwait. With an Air Force Reserve crew called to active duty, Azrael was sent to the Al Jahra highway (Highway 80) between Kuwait City and Basra, Iraq, to intercept the convoys of tanks, trucks, buses, and cars fleeing the battle. Facing SA-6 and SA-8 surface-to-air missiles and 37 mm and 57 mm radar-guided anti-aircraft artillery the crew attacked and destroyed or disabled most of the convoys. Azrael was also assigned to the 919th Special Operations Wing and retired to the museum in October 1995. Another AC-130A, AF serial no. 54–1626, the original prototype AC-130 named "Gunship II" is on display at the outdoor Air Park at the National Museum of the United States Air Force at Wright-Patterson AFB, Ohio. This aircraft served in Southeast Asia from 1967 to 1972, then served in JC-130A test configuration. It was transferred to the National Museum of the United States Air Force in 1976, and converted back to AC-130A configuration in the late 1990s. AC-130A serial no. 54–1623, c/n 3010, named "Ghost Rider" served in Southeast Asia and later conflicts until being retired in 1997 to Dobbins AFB, Georgia. Ghost Rider eventually was transferred and displayed at the Aviation Wing Museum at Marietta, Georgia. AC-130H serial no. 69-6575, named "Wicked Wanda" is on display at the Hurlburt Field, FL airpark. Hurlburt Field adds AC-130H, MC-130 to air park AC-130U serial no. 87-0128, named "Big Daddy" is on display at the Hurlburt Field, FL airpark.

Arbitrage

In economics and finance, arbitrage (, ) is the practice of taking advantage of a difference in prices in two or more markets; striking a combination of matching deals to capitalise on the difference, the profit being the difference between the market prices at which the unit is traded. When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit after transaction costs. For example, an arbitrage opportunity is present when there is the possibility to instantaneously buy something for a low price and sell it for a higher price. In principle and in academic use, an arbitrage is risk-free; in common use, as in statistical arbitrage, it may refer to expected profit, though losses may occur, and in practice, there are always risks in arbitrage, some minor (such as fluctuation of prices decreasing profit margins), some major (such as devaluation of a currency or derivative). In academic use, an arbitrage involves taking advantage of differences in price of a single asset or identical cash-flows; in common use, it is also used to refer to differences between similar assets (relative value or convergence trades), as in merger arbitrage. The term is mainly applied to trading in financial instruments, such as bonds, stocks, derivatives, commodities, and currencies. People who engage in arbitrage are called arbitrageurs (). Arbitrage has the effect of causing prices of the same or very similar assets in different markets to converge. Etymology "Arbitrage" is a French word and denotes a decision by an arbitrator or arbitration tribunal (in modern French, "" usually means referee or umpire). In the sense used here, it was first defined in 1704 by Mathieu de la Porte in his treatise "" as a consideration of different exchange rates to recognise the most profitable places of issuance and settlement for a bill of exchange (" [, in modern spelling] ".) Arbitrage-free If the market prices do not allow for profitable arbitrage, the prices are said to constitute an arbitrage equilibrium, or an arbitrage-free market. An arbitrage equilibrium is a precondition for a general economic equilibrium. The "no arbitrage" assumption is used in quantitative finance to calculate a unique risk neutral price for derivatives. Arbitrage-free pricing approach for bonds Arbitrage-free pricing for bonds is the method of valuing a coupon-bearing financial instrument by discounting its future cash flows by multiple discount rates. By doing so, a more accurate price can be obtained than if the price is calculated with a present-value pricing approach. Arbitrage-free pricing is used for bond valuation and to detect arbitrage opportunities for investors. For the purpose of valuing the price of a bond, its cash flows can each be thought of as packets of incremental cash flows with a large packet upon maturity, being the principal. Since the cash flows are dispersed throughout future periods, they must be discounted back to the present. In the present-value approach, the cash flows are discounted with one discount rate to find the price of the bond. In arbitrage-free pricing, multiple discount rates are used. The present-value approach assumes that the bond yield will stay the same until maturity. This is a simplified model because interest rates may fluctuate in the future, which in turn affects the yield on the bond. For this reason, the discount rate may differ for each cash flow. Each cash flow can be considered a zero-coupon instrument that pays one payment upon maturity. The discount rates used should be the rates of multiple zero-coupon bonds with maturity dates the same as each cash flow and similar risk as the instrument being valued. By using multiple discount rates, the arbitrage-free price is the sum of the discounted cash flows. Arbitrage-free price refers to the price at which no price arbitrage is possible. The idea of using multiple discount rates obtained from zero-coupon bonds and discounting a similar bond's cash flow to find its price is derived from the yield curve, which is a curve of the yields of the same bond with different maturities. This curve can be used to view trends in market expectations of how interest rates will move in the future. In arbitrage-free pricing of a bond, a yield curve of similar zero-coupon bonds with different maturities is created. If the curve were to be created with Treasury securities of different maturities, they would be stripped of their coupon payments through bootstrapping. This is to transform the bonds into zero-coupon bonds. The yield of these zero-coupon bonds would then be plotted on a diagram with time on the x-axis and yield on the y-axis. Since the yield curve displays market expectations on how yields and interest rates may move, the arbitrage-free pricing approach is more realistic than using only one discount rate. Investors can use this approach to value bonds and find price mismatches, resulting in an arbitrage opportunity. If a bond valued with the arbitrage-free pricing approach turns out to be priced higher in the market, an investor could have such an opportunity: Investor shorts the bond at price at time t1. Investor longs the zero-coupon bonds making up the related yield curve and strips and sells any coupon payments at t1. As t>t1, the price spread between the prices will decrease. At maturity, the prices will converge and be equal. Investor exits both the long and short positions, realising a profit. If the outcome from the valuation were the reverse case, the opposite positions would be taken in the bonds. This arbitrage opportunity comes from the assumption that the prices of bonds with the same properties will converge upon maturity. This can be explained through market efficiency, which states that arbitrage opportunities will eventually be discovered and corrected. The prices of the bonds in t1 move closer together to finally become the same at tT. Conditions for arbitrage Arbitrage may take place when: the same asset does not trade at the same price on all markets ("the law of one price"). two assets with identical cash flows do not trade at the same price. an asset with a known price in the future does not today trade at its future price discounted at the risk-free interest rate (or the asset has significant costs of storage; so this condition holds true for something like grain but not for securities). Arbitrage is not simply the act of buying a product in one market and selling it in another for a higher price at some later time. The transactions must occur simultaneously to avoid exposure to market risk, or the risk that prices may change in one market before both transactions are complete. In practical terms, this is generally possible only with securities and financial products that can be traded electronically, and even then, when each leg of the trade is executed, the prices in the market may have moved. Missing one of the legs of the trade (and subsequently having to trade it soon after at a worse price) is called 'execution risk' or more specifically 'leg risk'. In the simplest example, any good sold in one market should sell for the same price in another. Traders may, for example, find that the price of wheat is lower in agricultural regions than in cities, purchase the good, and transport it to another region to sell at a higher price. This type of price arbitrage is the most common, but this simple example ignores the cost of transport, storage, risk, and other factors. "True" arbitrage requires that there is no market risk involved. Where securities are traded on more than one exchange, arbitrage occurs by simultaneously buying in one and selling on the other. See rational pricing, particularly § arbitrage mechanics, for further discussion. Mathematically it is defined as follows: where , denotes the portfolio value at time t and T is the time the portfolio ceases to be available on the market. This means that the value of the portfolio is never negative, and guaranteed to be positive at least once over its lifetime. Negative, or anti-, arbitrage is similarly defined as and occurs naturally in arbitrage relations as the seller view as opposed to the buyer view. Price convergence Arbitrage has the effect of causing prices in different markets to converge. As a result of arbitrage, the currency exchange rates, the price of commodities, and the price of securities in different markets tend to converge. The speed at which they do so is a measure of market efficiency. Arbitrage tends to reduce price discrimination by encouraging people to buy an item where the price is low and resell it where the price is high (as long as the buyers are not prohibited from reselling and the transaction costs of buying, holding, and reselling are small, relative to the difference in prices in the different markets). Arbitrage moves different currencies toward purchasing power parity. Assume that a car purchased in the United States is cheaper than the same car in Canada. Canadians would buy their cars across the border to exploit the arbitrage condition. At the same time, Americans would buy US cars, transport them across the border, then sell them in Canada. Canadians would have to buy American dollars to buy the cars and Americans would have to sell the Canadian dollars they received in exchange. Both actions would increase demand for US dollars and supply of Canadian dollars. As a result, there would be an appreciation of the US currency. This would make US cars more expensive and Canadian cars less so until their prices were similar. On a larger scale, international arbitrage opportunities in commodities, goods, securities, and currencies tend to change exchange rates until the purchasing power is equal. In reality, most assets exhibit some difference between countries. These, transaction costs, taxes, and other costs provide an impediment to this kind of arbitrage. Similarly, arbitrage affects the difference in interest rates paid on government bonds issued by the various countries, given the expected depreciation in the currencies relative to each other (see interest rate parity). Risks Arbitrage transactions in modern securities markets involve fairly low day-to-day risks, but can face extremely high risk in rare situations, particularly financial crises, and can lead to bankruptcy. Formally, arbitrage transactions have negative skew – prices can get a small amount closer (but often no closer than 0), while they can get very far apart. The day-to-day risks are generally small because the transactions involve small differences in price, so an execution failure will generally cause a small loss (unless the trade is very big or the price moves rapidly). The rare case risks are extremely high because these small price differences are converted to large profits via leverage (borrowed money), and in the rare event of a large price move, this may yield a large loss. The principal risk, which is typically encountered on a routine basis, is classified as execution risk. This transpires when an aspect of the financial transaction does not materialize as anticipated. Infrequent, albeit critical, risks encompass counterparty and liquidity risks. The former, counterparty risk, is characterized by the failure of the other participant in a substantial transaction, or a series of transactions, to fulfill their financial obligations. Liquidity risk, conversely, emerges when an entity is necessitated to allocate additional monetary resources as margin, but encounters a deficit in the required capital. In the academic literature, the idea that seemingly very low-risk arbitrage trades might not be fully exploited because of these risk factors and other considerations is often referred to as limits to arbitrage. Execution risk Generally, it is impossible to close two or three transactions at the same instant; therefore, there is the possibility that when one part of the deal is closed, a quick shift in prices makes it impossible to close the other at a profitable price. However, this is not necessarily the case. Many exchanges and inter-dealer brokers allow multi legged trades (e.g. basis block trades on LIFFE). Competition in the marketplace can also create risks during arbitrage transactions. As an example, if one was trying to profit from a price discrepancy between IBM on the NYSE and IBM on the London Stock Exchange, they may purchase a large number of shares on the NYSE and find that they cannot simultaneously sell on the LSE. This leaves the arbitrageur in an unhedged risk position. In the 1980s, risk arbitrage was common. In this form of speculation, one trades a security that is clearly undervalued or overvalued, when it is seen that the wrong valuation is about to be corrected. The standard example is the stock of a company, undervalued in the stock market, which is about to be the object of a takeover bid; the price of the takeover will more truly reflect the value of the company, giving a large profit to those who bought at the current price, if the merger goes through as predicted. Traditionally, arbitrage transactions in the securities markets involve high speed, high volume, and low risk. At some moment a price difference exists, and the problem is to execute two or three balancing transactions while the difference persists (that is, before the other arbitrageurs act). When the transaction involves a delay of weeks or months, as above, it may entail considerable risk if borrowed money is used to magnify the reward through leverage. One way of reducing this risk is through the illegal use of inside information, and risk arbitrage in leveraged buyouts was associated with some of the famous financial scandals of the 1980s, such as those involving Michael Milken and Ivan Boesky. Mismatch Another risk occurs if the items being bought and sold are not identical and the arbitrage is conducted under the assumption that the prices of the items are correlated or predictable; this is more narrowly referred to as a convergence trade. In the extreme case this is merger arbitrage, described below. In comparison to the classical quick arbitrage transaction, such an operation can produce disastrous losses. Counterparty risk As arbitrages generally involve future movements of cash, they are subject to counterparty risk: the risk that a counterparty fails to fulfill their side of a transaction. This is a serious problem if one has either a single trade or many related trades with a single counterparty, whose failure thus poses a threat, or in the event of a financial crisis when many counterparties fail. This hazard is serious because of the large quantities one must trade in order to make a profit on small price differences. For example, if one purchases many risky bonds, then hedges them with CDSes, profiting from the difference between the bond spread and the CDS premium, in a financial crisis, the bonds may default and the CDS writer/seller may fail, due to the stress of the crisis, causing the arbitrageur to face steep losses. Liquidity risk Arbitrage trades are necessarily synthetic, leveraged trades, as they involve a short position. If the assets used are not identical (so a price divergence makes the trade temporarily lose money), or the margin treatment is not identical, and the trader is accordingly required to post margin (faces a margin call), the trader may run out of capital (if they run out of cash and cannot borrow more) and be forced to sell these assets at a loss even though the trades may be expected to ultimately make money. In effect, arbitrage traders synthesise a put option on their ability to finance themselves. Prices may diverge during a financial crisis, often termed a "flight to quality"; these are precisely the times when it is hardest for leveraged investors to raise capital (due to overall capital constraints), and thus they will lack capital precisely when they need it most. Gray market Grey market arbitrage is the sale of goods purchased through informal channels to earn the difference in price. Excessive gray market arbitrage will lead to arbitrage behaviors in formal channels, which will reduce returns due to factors such as price confusion, and may even cause prices to plummet in severe cases. Types Spatial arbitrage Also known as geographical arbitrage, this is the simplest form of arbitrage. In spatial arbitrage, an arbitrageur looks for price differences between geographically separate markets. For example, there may be a bond dealer in Virginia offering a bond at 100-12/23 and a dealer in Washington bidding 100-15/23 for the same bond. For whatever reason, the two dealers have not spotted the difference in the prices, but the arbitrageur does. The arbitrageur immediately buys the bond from the Virginia dealer and sells it to the Washington dealer. Latency arbitrage For very short amounts of time, the prices of two assets that are either fungible or related by a strict pricing relationship may temporarily go out of sync as the market makers are slow to update the prices. This momentary mispricing creates the opportunity for an arbitrageur to capture the difference between the two prices. For example, the price of calls and puts on an underlying should be related by put-call parity. If these prices are misquoted relative to the put-call parity relationship, it provides an arbitrageur the opportunity to profit from the mispricing. Latency arbitrage is often mentioned especially in an electronic trading environment, where the use of fast server hardware allows an arbitrageur to capture realize opportunities that may exist for as little as nanoseconds. A study by the Financial Conduct Authority of the United Kingdom found that this practice generates as much as $5 billion per year in profit. Merger arbitrage Also called risk arbitrage, merger arbitrage generally consists of buying/holding the stock of a company that is the target of a takeover while shorting the stock of the acquiring company. Usually, the market price of the target company is less than the price offered by the acquiring company. The spread between these two prices depends mainly on the probability and the timing of the takeover being completed as well as the prevailing level of interest rates. The bet in a merger arbitrage is that such a spread will eventually be zero, if and when the takeover is completed. The risk is that the deal "breaks" and the spread massively widens. Municipal bond arbitrage Also called municipal bond relative value arbitrage, municipal arbitrage, or just muni arb, this hedge fund strategy involves one of two approaches. The term "arbitrage" is also used in the context of the Income Tax Regulations governing the investment of proceeds of municipal bonds; these regulations, aimed at the issuers or beneficiaries of tax-exempt municipal bonds, are different and, instead, attempt to remove the issuer's ability to arbitrage between the low tax-exempt rate and a taxable investment rate. Generally, managers seek relative value opportunities by being both long and short municipal bonds with a duration-neutral book. The relative value trades may be between different issuers, different bonds issued by the same entity, or capital structure trades referencing the same asset (in the case of revenue bonds). Managers aim to capture the inefficiencies arising from the heavy participation of non-economic investors (i.e., high income "buy and hold" investors seeking tax-exempt income) as well as the "crossover buying" arising from corporations' or individuals' changing income tax situations (i.e., insurers switching their munis for corporates after a large loss as they can capture a higher after-tax yield by offsetting the taxable corporate income with underwriting losses). There are additional inefficiencies arising from the highly fragmented nature of the municipal bond market which has two million outstanding issues and 50,000 issuers, in contrast to the Treasury market which has 400 issues and a single issuer. Second, managers construct leveraged portfolios of AAA- or AA-rated tax-exempt municipal bonds with the duration risk hedged by shorting the appropriate ratio of taxable corporate bonds. These corporate equivalents are typically interest rate swaps referencing Libor or SIFMA. The arbitrage manifests itself in the form of a relatively cheap longer maturity municipal bond, which is a municipal bond that yields significantly more than 65% of a corresponding taxable corporate bond. The steeper slope of the municipal yield curve allows participants to collect more after-tax income from the municipal bond portfolio than is spent on the interest rate swap; the carry is greater than the hedge expense. Positive, tax-free carry from muni arb can reach into the double digits. The bet in this municipal bond arbitrage is that, over a longer period of time, two similar instruments—municipal bonds and interest rate swaps—will correlate with each other; they are both very high quality credits, have the same maturity and are denominated in the same currency. Credit risk and duration risk are largely eliminated in this strategy. However, basis risk arises from use of an imperfect hedge, which results in significant, but range-bound principal volatility. The end goal is to limit this principal volatility, eliminating its relevance over time as the high, consistent, tax-free cash flow accumulates. Since the inefficiency is related to government tax policy, and hence is structural in nature, it has not been arbitraged away. However, many municipal bonds are callable, and this adds substantial risks to the strategy. Convertible bond arbitrage A convertible bond is a bond that an investor can return to the issuing company in exchange for a predetermined number of shares in the company. A convertible bond can be thought of as a corporate bond with a stock call option attached to it. The price of a convertible bond is sensitive to three major factors: interest rate. When rates move higher, the bond part of a convertible bond tends to move lower, but the call option part of a convertible bond moves higher (and the aggregate tends to move lower). stock price. When the price of the stock the bond is convertible into moves higher, the price of the bond tends to rise. credit spread. If the creditworthiness of the issuer deteriorates (e.g. rating downgrade) and its credit spread widens, the bond price tends to move lower, but, in many cases, the call option part of the convertible bond moves higher (since credit spread correlates with volatility). Given the complexity of the calculations involved and the convoluted structure that a convertible bond can have, an arbitrageur often relies on sophisticated quantitative models in order to identify bonds that are trading cheap versus their theoretical value. Convertible arbitrage consists of buying a convertible bond and hedging two of the three factors in order to gain exposure to the third factor at a very attractive price. For instance an arbitrageur would first buy a convertible bond, then sell fixed income securities or interest rate futures (to hedge the interest rate exposure) and buy some credit protection (to hedge the risk of credit deterioration). Eventually what he or she would be left with is something similar to a call option on the underlying stock, acquired at a very low price. He or she could then make money either selling some of the more expensive options that are openly traded in the market or delta hedging his or her exposure to the underlying shares. Depository receipts A depositary receipt is a security that is offered as a "tracking stock" on another foreign market. For instance, a Chinese company wishing to raise more money may issue a depository receipt on the New York Stock Exchange, as the amount of capital on the local exchanges is limited. These securities, known as ADRs (American depositary receipt) or GDRs (global depository receipt) depending on where they are issued, are typically considered "foreign" and therefore trade at a lower value when first released. Many ADR's are exchangeable into the original security (known as fungibility) and actually have the same value. In this case, there is a spread between the perceived value and real value, which can be extracted. Other ADR's that are not exchangeable often have much larger spreads. Since the ADR is trading at a value lower than what it is worth, one can purchase the ADR and expect to make money as its value converges on the original. However, there is a chance that the original stock will fall in value too, so by shorting it one can hedge that risk. Cross-border arbitrage Cross-border arbitrage exploits different prices of the same stock in different countries: Example: Apple is trading on NASDAQ at US$108.84. The stock is also traded on the German electronic exchange, XETRA. If 1 euro costs US$1.11, a cross-border trader could enter a buy order on the XETRA at €98.03 per Apple share and a sell order at €98.07 per share. Some brokers in Germany do not offer access to the U.S. exchanges. Hence if a German retail investor wants to buy Apple stock, he needs to buy it on the XETRA. The cross-border trader would sell the Apple shares on XETRA to the investor and buy the shares in the same second on NASDAQ. Afterwards, the cross-border trader would need to transfer the shares bought on NASDAQ to the German XETRA exchange, where he is obliged to deliver the stock. In most cases, the quotation on the local exchanges is done electronically by high-frequency traders, taking into consideration the home price of the stock and the exchange rate. This kind of high-frequency trading benefits the public, as it reduces the cost to the German investor and enables them to buy U.S. shares. Dual-listed companies A dual-listed company (DLC) structure involves two companies incorporated in different countries contractually agreeing to operate their businesses as if they were a single enterprise, while retaining their separate legal identity and existing stock exchange listings. In integrated and efficient financial markets, stock prices of the twin pair should move in lockstep. In practice, DLC share prices exhibit large deviations from theoretical parity. Arbitrage positions in DLCs can be set up by obtaining a long position in the relatively underpriced part of the DLC and a short position in the relatively overpriced part. Such arbitrage strategies start paying off as soon as the relative prices of the two DLC stocks converge toward theoretical parity. However, since there is no identifiable date at which DLC prices will converge, arbitrage positions sometimes have to be kept open for considerable periods of time. In the meantime, the price gap might widen. In these situations, arbitrageurs may receive margin calls, after which they would most likely be forced to liquidate part of the position at a highly unfavorable moment and suffer a loss. Arbitrage in DLCs may be profitable, but is also very risky. A good illustration of the risk of DLC arbitrage is the position in Royal Dutch Shell—which had a DLC structure until 2005—by the hedge fund Long-Term Capital Management (LTCM, see also the discussion below). Lowenstein (2000) describes that LTCM established an arbitrage position in Royal Dutch Shell in the summer of 1997, when Royal Dutch traded at an 8 to 10 percent premium. In total, $2.3 billion was invested, half of which was long in Shell and the other half was short in Royal Dutch (Lowenstein, p. 99). In the autumn of 1998, large defaults on Russian debt created significant losses for the hedge fund and LTCM had to unwind several positions. Lowenstein reports that the premium of Royal Dutch had increased to about 22 percent and LTCM had to close the position and incur a loss. According to Lowenstein (p. 234), LTCM lost $286 million in equity pairs trading and more than half of this loss is accounted for by the Royal Dutch Shell trade. (See further under Limits to arbitrage.) Private to public equities The market prices for privately held companies are typically viewed from a return on investment perspective (such as 25%), whilst publicly held and or exchange listed companies trade on a price to earnings ratio (P/E) (such as a P/E of 10, which equates to a 10% ROI). Thus, if a publicly traded company specialises in the acquisition of privately held companies, from a per-share perspective there is a gain with every acquisition that falls within these guidelines. E.g., Berkshire Hathaway. Private to public equities arbitrage is a term that can arguably be applied to investment banking in general. Private markets to public markets differences may also help explain the overnight windfall gains enjoyed by principals of companies that just did an initial public offering (IPO). Regulatory arbitrage Regulatory arbitrage "is an avoidance strategy of regulation that is exercised as a result of a regulatory inconsistency". In other words, where a regulated institution takes advantage of the difference between its real (or economic) risk and the regulatory position. For example, if a bank, operating under the Basel I accord, has to hold 8% capital against default risk, but the real risk of default is lower, it is profitable to securitise the loan, removing the low-risk loan from its portfolio. On the other hand, if the real risk is higher than the regulatory risk then it is profitable to make that loan and hold on to it, provided it is priced appropriately. Regulatory arbitrage can result in parts of entire businesses being unregulated as a result of the arbitrage. This process can increase the overall riskiness of institutions under a risk insensitive regulatory regime, as described by Alan Greenspan in his October 1998 speech on The Role of Capital in Optimal Banking Supervision and Regulation. The term "Regulatory Arbitrage" was used for the first time in 2005 when it was applied by Scott V. Simpson, a partner at law firm Skadden, Arps, to refer to a new defence tactic in hostile mergers and acquisitions where differing takeover regimes in deals involving multi-jurisdictions are exploited to the advantage of a target company under threat. In economics, regulatory arbitrage (sometimes, tax arbitrage) may refer to situations when a company can choose a nominal place of business with a regulatory, legal or tax regime with lower costs. This can occur particularly where the business transaction has no obvious physical location. In the case of many financial products, it may be unclear "where" the transaction occurs. Regulatory arbitrage can include restructuring a bank by outsourcing services such as IT. The outsourcing company takes over the installations, buying out the bank's assets and charges a periodic service fee back to the bank. This frees up cashflow usable for new lending by the bank. The bank will have higher IT costs, but counts on the multiplier effect of money creation and the interest rate spread to make it a profitable exercise. Example: Suppose the bank sells its IT installations for US$40 million. With a reserve ratio of 10%, the bank can create US$400 million in additional loans (there is a time lag, and the bank has to expect to recover the loaned money back into its books). The bank can often lend (and securitize the loan) to the IT services company to cover the acquisition cost of the IT installations. This can be at preferential rates, as the sole client using the IT installation is the bank. If the bank can generate 5% interest margin on the 400 million of new loans, the bank will increase interest revenues by 20 million. The IT services company is free to leverage their balance sheet as aggressively as they and their banker agree to. This is the reason behind the trend towards outsourcing in the financial sector. Without this money creation benefit, it is actually more expensive to outsource the IT operations as the outsourcing adds a layer of management and increases overhead. According to PBS Frontline's 2012 four-part documentary, "Money, Power, and Wall Street", regulatory arbitrage, along with asymmetric bank lobbying in Washington and abroad, allowed investment banks in the pre- and post-2008 period to continue to skirt laws and engage in the risky proprietary trading of opaque derivatives, swaps, and other credit-based instruments invented to circumvent legal restrictions at the expense of clients, government, and publics. Due to the Affordable Care Act's expansion of Medicaid coverage, one form of Regulatory Arbitrage can now be found when businesses engage in "Medicaid Migration", a maneuver by which qualifying employees who would typically be enrolled in company health plans elect to enroll in Medicaid instead. These programs that have similar characteristics as insurance products to the employee, but have radically different cost structures, resulting in significant expense reductions for employers. Telecom arbitrage Telecom arbitrage companies allow phone users to make international calls for free through certain access numbers. Such services are offered in the United Kingdom; the telecommunication arbitrage companies get paid an interconnect charge by the UK mobile networks and then buy international routes at a lower cost. The calls are seen as free by the UK contract mobile phone customers since they are using up their allocated monthly minutes rather than paying for additional calls. Such services were previously offered in the United States by companies such as FuturePhone.com. These services would operate in rural telephone exchanges, primarily in small towns in the state of Iowa. In these areas, the local telephone carriers are allowed to charge a high "termination fee" to the caller's carrier in order to fund the cost of providing service to the small and sparsely populated areas that they serve. However, FuturePhone (as well as other similar services) ceased operations upon legal challenges from AT&T and other service providers. Statistical arbitrage Statistical arbitrage is an imbalance in expected nominal values. A casino has a statistical arbitrage in every game of chance that it offers, referred to as the house advantage, house edge, vigorish, or house vigorish. Gray market To accomplish arbitrage, the grey market buys items through marketing channels that sell them without the permission of the product trademark owner and sells them in the legitimate market. A Swiss watch sold by an approved dealer for £42,600 is an excellent example of a grey market product; customers can buy the identical watch for £27,227 on the Chrono24 website, which is an unlicensed 'grey market.' The fall of Long-Term Capital Management Long-Term Capital Management (LTCM) lost 4.6 billion U.S. dollars in fixed income arbitrage in September 1998. LTCM had attempted to make money on the price difference between different bonds. For example, it would sell U.S. Treasury securities and buy Italian bond futures. The concept was that because Italian bond futures had a less liquid market, in the short term Italian bond futures would have a higher return than U.S. bonds, but in the long term, the prices would converge. Because the difference was small, a large amount of money had to be borrowed to make the buying and selling profitable. The downfall in this system began on August 17, 1998, when Russia defaulted on its ruble debt and domestic dollar debt. Because global markets were already nervous due to the 1997 Asian financial crisis, investors began selling non-U.S. treasury debt and buying U.S. treasuries, which were considered a safe investment. As a result, the price on US treasuries began to increase and the return began decreasing because there were many buyers, and the return (yield) on other bonds began to increase because there were many sellers (i.e. the price of those bonds fell). This caused the difference between the prices of U.S. treasuries and other bonds to increase, rather than to decrease as LTCM was expecting. Eventually this caused LTCM to fold, and their creditors had to arrange a bail-out. More controversially, officials of the Federal Reserve assisted in the negotiations that led to this bail-out, on the grounds that so many companies and deals were intertwined with LTCM that if LTCM actually failed, they would as well, causing a collapse in confidence in the economic system. Thus LTCM failed as a fixed income arbitrage fund, although it is unclear what sort of profit was realised by the banks that bailed LTCM out.

ANSI C

ANSI C, ISO C, and Standard C are successive standards for the C programming language published by the American National Standards Institute (ANSI) and ISO/IEC JTC 1/SC 22/WG 14 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Historically, the names referred specifically to the original and best-supported version of the standard (known as C89 or C90). Software developers writing in C are encouraged to conform to the standards, as doing so helps portability between compilers. History and outlook The first standard for C was published by ANSI. Although this document was subsequently adopted by ISO/IEC and subsequent revisions published by ISO/IEC have been adopted by ANSI, "ANSI C" is still used to refer to the standard. While some software developers use the term ISO C, others are standards-body neutral and use Standard C. Informal specification: K&R C (C78) Informal specification in 1978 (Brian Kernighan and Dennis Ritchie book The C Programming Language). Standardizing C In 1983, the American National Standards Institute formed a committee, X3J11, to establish a standard specification of C. In 1985, the first Standard Draft was released, sometimes referred to as C85. In 1986, another Draft Standard was released, sometimes referred to as C86. The prerelease Standard C was published in 1988, and sometimes referred to as C88. C89 The ANSI standard was completed in 1989 and ratified as ANSI X3.159-1989 "Programming Language C." This version of the language is often referred to as "ANSI C". Later on sometimes the label "C89" is used to distinguish it from C90 but using the same labeling method. C90 The same standard as C89 was ratified by ISO/IEC as ISO/IEC 9899:1990, with only formatting changes, which is sometimes referred to as C90. Therefore, the terms "C89" and "C90" refer to essentially the same language. This standard has been withdrawn by both ANSI/INCITS and ISO/IEC. C95 In 1995, the ISO/IEC published an extension, called Amendment 1, for the ANSI-C standard. Its full name finally was ISO/IEC 9899:1990/AMD1:1995 or nicknamed C95. Aside from error correction there were further changes to the language capabilities, such as: Improved multi-byte and wide character support in the standard library, introducing <wchar.h> and <wctype.h> as well as multi-byte I/O Addition of digraphs to the language Specification of standard macros for the alternative specification of operators, e.g. and for && Specification of the standard macro __STDC_VERSION__ In addition to the amendment, two technical corrigenda were published by ISO for C90: ISO/IEC 9899:1990/Cor 1:1994 TCOR1 in 1994 ISO/IEC 9899:1990/Cor 2:1996 in 1996 Preprocessor test for C95 compatibility #if defined(__STDC_VERSION__) && __STDC_VERSION__ >= 199409L /* C95 compatible source code. */ #elif defined() /* C89 compatible source code. */ #endif C99 In March 2000, ANSI adopted the ISO/IEC 9899:1999 standard. This standard is commonly referred to as C99. Some notable additions to the previous standard include: New built-in data types: long long, _Bool, _Complex, and _Imaginary Several new core language features, including static array indices, designated initializers, compound literals, variable-length arrays, flexible array members, variadic macros, and restrict keyword Several new library headers, including stdint.h, <tgmath.h>, fenv.h, <complex.h> Improved compatibility with several C++ features, including inline functions, single-line comments with //, mixing declarations and code, and universal character names in identifiers Removed several dangerous C89 language features such as implicit function declarations and implicit int Three technical corrigenda were published by ISO for C99: ISO/IEC 9899:1999/Cor 1:2001(E) ISO/IEC 9899:1999/Cor 2:2004(E) ISO/IEC 9899:1999/Cor 3:2007(E), notable for deprecating the standard library function gets This standard has been withdrawn by both ANSI/INCITS and ISO/IEC in favour of C11. C11 C11 was officially ratified and published on December 8, 2011. Notable features include improved Unicode support, type-generic expressions using the new _Generic keyword, a cross-platform multi-threading API (threads.h), and atomic types support in both core language and the library (stdatomic.h). One technical corrigendum has been published by ISO for C11: ISO/IEC 9899:2011/Cor 1:2012 C17 , "C17" is the current standard for the C programming language. C17 addresses defects in C11 without introducing new language features. C23 C23 is the informal name for the next major C language standard revision. Other related ISO publications As part of the standardization process, ISO/IEC also publishes technical reports and specifications related to the C language: ISO/IEC TR 19769:2004, on library extensions to support Unicode transformation formats, integrated into C11 ISO/IEC TR 24731-1:2007, on library extensions to support bounds-checked interfaces, integrated into C11 ISO/IEC TR 18037:2008, on embedded C extensions ISO/IEC TR 24732:2009, on decimal floating point arithmetic, superseded by ISO/IEC TS 18661-2:2015 ISO/IEC TR 24747:2009, on special mathematical functions, ISO/IEC TR 24731-2:2010, on library extensions to support dynamic allocation functions ISO/IEC TS 17961:2013, on secure coding in C ISO/IEC TS 18661-1:2014, on IEC 60559:2011-compatible binary floating-point arithmetic ISO/IEC TS 18661-2:2015, on IEC 60559:2011-compatible decimal floating point arithmetic ISO/IEC TS 18661-3:2015, on IEC 60559:2011-compatible interchange and extended floating-point types ISO/IEC TS 18661-4:2015, on IEC 60559:2011-compatible supplementary functions More technical specifications are in development and pending approval, including the fifth and final part of TS 18661, a software transactional memory specification, and parallel library extensions. Support from major compilers ANSI C is now supported by almost all the widely used compilers. GCC and Clang are two major C compilers popular today, both are based on the C11 with updates including changes from later specifications such as C17 and C18. Any source code written only in standard C and without any hardware dependent assumptions is virtually guaranteed to compile correctly on any platform with a conforming C implementation. Without such precautions, most programs may compile only on a certain platform or with a particular compiler, due, for example, to the use of non-standard libraries, such as GUI libraries, or to the reliance on compiler- or platform-specific attributes such as the exact size of certain data types and byte endianness. Compliance detectability To mitigate the differences between K&R C and the ANSI C standard, the ("standard c") macro can be used to split code into ANSI and K&R sections. #if defined() && extern int getopt(int, char * const *, const char *); #else extern int getopt(); #endif In the above example, a prototype is used in a function declaration for ANSI compliant implementations, while an obsolescent non-prototype declaration is used otherwise. Those are still ANSI-compliant as of C99. Note how this code checks both definition and evaluation: this is because some implementations may set to zero to indicate non-ANSI compliance.

Atom probe

The atom probe was introduced at the 14th Field Emission Symposium in 1967 by Erwin Wilhelm Müller and J. A. Panitz. It combined a field ion microscope with a mass spectrometer having a single particle detection capability and, for the first time, an instrument could “... determine the nature of one single atom seen on a metal surface and selected from neighboring atoms at the discretion of the observer”. Atom probes are unlike conventional optical or electron microscopes, in that the magnification effect comes from the magnification provided by a highly curved electric field, rather than by the manipulation of radiation paths. The method is destructive in nature removing ions from a sample surface in order to image and identify them, generating magnifications sufficient to observe individual atoms as they are removed from the sample surface. Through coupling of this magnification method with time of flight mass spectrometry, ions evaporated by application of electric pulses can have their mass-to-charge ratio computed. Through successive evaporation of material, layers of atoms are removed from a specimen, allowing for probing not only of the surface, but also through the material itself. Computer methods are used to rebuild a three-dimensional view of the sample, prior to it being evaporated, providing atomic scale information on the structure of a sample, as well as providing the type atomic species information. The instrument allows the three-dimensional reconstruction of up to billions of atoms from a sharp tip (corresponding to specimen volumes of 10,000-10,000,000 nm3). Overview Atom probe samples are shaped to implicitly provide a highly curved electric potential to induce the resultant magnification, as opposed to direct use of lensing, such as via magnetic lenses. Furthermore, in normal operation (as opposed to a field ionization modes) the atom probe does not utilize a secondary source to probe the sample. Rather, the sample is evaporated in a controlled manner (field evaporation) and the evaporated ions are impacted onto a detector, which is typically 10 to 100 cm away. The samples are required to have a needle geometry and are produced by similar techniques as TEM sample preparation electropolishing, or focused ion beam methods. Since 2006, commercial systems with laser pulsing have become available and this has expanded applications from metallic only specimens into semiconducting, insulating such as ceramics, and even geological materials. Preparation is done, often by hand, to manufacture a tip radius sufficient to induce a high electric field, with radii on the order of 100 nm. To conduct an atom probe experiment a very sharp needle shaped specimen is placed in an ultra high vacuum chamber. After introduction into the vacuum system, the sample is reduced to cryogenic temperatures (typically 20-100 K) and manipulated such that the needle's point is aimed towards an ion detector. A high voltage is applied to the specimen, and either a laser pulse is applied to the specimen or a voltage pulse (typically 1-2 kV) with pulse repetition rates in the hundreds of kilohertz range is applied to a counter electrode. The application of the pulse to the sample allows for individual atoms at the sample surface to be ejected as an ion from the sample surface at a known time. Typically the pulse amplitude and the high voltage on the specimen are computer controlled to encourage only one atom to ionize at a time, but multiple ionizations are possible. The delay between application of the pulse and detection of the ion(s) at the detector allow for the computation of a mass-to-charge ratio. Whilst the uncertainty in the atomic mass computed by time-of-flight methods in atom probe is sufficiently small to allow for detection of individual isotopes within a material this uncertainty may still, in some cases, confound definitive identification of atomic species. Effects such as superposition of differing ions with multiple electrons removed, or through the presence of complex species formation during evaporation may cause two or more species to have sufficiently close time-of-flights to make definitive identification impossible. History Field ion microscopy Field ion microscopy is a modification of field emission microscopy where a stream of tunneling electrons is emitted from the apex of a sharp needle-like tip cathode when subjected to a sufficiently high electric field (~3-6 V/nm). The needle is oriented towards a phosphor screen to create a projected image of the work function at the tip apex. The image resolution is limited to (2-2.5 nm), due to quantum mechanical effects and lateral variations in the electron velocity. In field ion microscopy the tip is cooled by a cryogen and its polarity is reversed. When an imaging gas (usually hydrogen or helium) is introduced at low pressures (< 0.1 Pascal) gas ions in the high electric field at the tip apex are field ionized and produce a projected image of protruding atoms at the tip apex. The image resolution is determined primarily by the temperature of the tip but even at 78 Kelvin atomic resolution is achieved. 10-cm Atom Probe The 10-cm Atom Probe, invented in 1973 by J. A. Panitz was a “new and simple atom probe which permits rapid, in depth species identification or the more usual atom-by atom analysis provided by its predecessors ... in an instrument having a volume of less than two liters in which tip movement is unnecessary and the problems of evaporation pulse stability and alignment common to previous designs have been eliminated.” This was accomplished by combining a time of flight (TOF) mass spectrometer with a proximity focussed, dual channel plate detector, an 11.8 cm drift region and a 38° field of view. An FIM image or a desorption image of the atoms removed from the apex of a field emitter tip could be obtained. The 10-cm Atom Probe has been called the progenitor of later atom probes including the commercial instruments. Imaging Atom Probe The Imaging Atom-Probe (IAP) was introduced in 1974 by J. A. Panitz. It incorporated the features of the 10-cm Atom-Probe yet “... departs completely from [previous] atom probe philosophy. Rather than attempt to determine the identity of a surface species producing a preselected ion-image spot, we wish to determine the complete crystallographic distribution of a surface species of preselected mass-to-charge ratio. Now suppose that instead of operating the [detector] continuously, it is turned on for a short time coincidentally with the arrival of a preselected species of interest by applying a gate pulse a time T after the evaporation pulse has reached the specimen. If the duration of the gate pulse is shorter than the travel time between adjacent species, only that surface species having the unique travel time T will be detected and its complete crystallographic distribution displayed.” It was patented in 1975 as the Field Desorption Spectrometer. The Imaging Atom-Probe moniker was coined by A. J. Waugh in 1978 and the instrument was described in detail by J. A. Panitz in the same year. Atom Probe Tomography (APT) Modern day atom probe tomography uses a position sensitive detector aka a FIM in a box to deduce the lateral location of atoms. The idea of the APT, inspired by J. A. Panitz's Field Desorption Spectrometer patent, was developed by Mike Miller starting in 1983 and culminated with the first prototype in 1986. Various refinements were made to the instrument, including the use of a so-called position-sensitive (PoS) detector by Alfred Cerezo, Terence Godfrey, and George D. W. Smith at Oxford University in 1988. The Tomographic Atom Probe (TAP), developed by researchers at the University of Rouen in France in 1993, introduced a multichannel timing system and multianode array. Both instruments (PoSAP and TAP) were commercialized by Oxford Nanoscience and CAMECA respectively. Since then, there have been many refinements to increase the field of view, mass and position resolution, and data acquisition rate of the instrument. The Local Electrode Atom Probe was first introduced in 2003 by Imago Scientific Instruments. In 2005, the commercialization of the pulsed laser atom probe (PLAP) expanded the avenues of research from highly conductive materials (metals) to poor conductors (semiconductors like silicon) and even insulating materials. AMETEK acquired CAMECA in 2007 and Imago Scientific Instruments (Madison, WI) in 2010, making the company the sole commercial developer of APTs with more than 110 instruments installed around the world in 2019. The first few decades of work with APT focused on metals. However, with the introduction of the laser pulsed atom probe systems applications have expanded to semiconductors, ceramic and geologic materials, with some work on biomaterials. The most advanced study of biological material to date using APT involved analyzing the chemical structure of teeth of the radula of chiton Chaetopleura apiculata. In this study, the use of APT showed chemical maps of organic fibers in the surrounding nano-crystalline magnetite in the chiton teeth, fibers which were often co-located with sodium or magnesium. This has been furthered to study elephant tusks, dentin and human enamel. Theory Field evaporation Field evaporation is an effect that can occur when an atom bonded at the surface of a material is in the presence of a sufficiently high and appropriately directed electric field, where the electric field is the differential of electric potential (voltage) with respect to distance. Once this condition is met, it is sufficient that local bonding at the specimen surface is capable of being overcome by the field, allowing for evaporation of an atom from the surface to which it is otherwise bonded. Ion flight Whether evaporated from the material itself, or ionised from the gas, the ions that are evaporated are accelerated by electrostatic force, acquiring most of their energy within a few tip-radii of the sample. Subsequently, the accelerative force on any given ion is controlled by the electrostatic equation, where n is the ionisation state of the ion, and e is the fundamental electric charge. This can be equated with the mass of the ion, m, via Newton's law (F=ma): Relativistic effects in the ion flight are usually ignored, as realisable ion speeds are only a very small fraction of the speed of light. Assuming that the ion is accelerated during a very short interval, the ion can be assumed to be travelling at constant velocity. As the ion will travel from the tip at voltage V1 to some nominal ground potential, the speed at which the ion is travelling can be estimated by the energy transferred into the ion during (or near) ionisation. Therefore, the ion speed can be computed with the following equation, which relates kinetic energy to energy gain due to the electric field, the negative arising from the loss of electrons forming a net positive charge. Where U is the ion velocity. Solving for U, the following relation is found: Let's say that for at a certain ionization voltage, a singly charged hydrogen ion acquires a resulting velocity of 1.4x10^6 ms−1 at 10~kV. A singly charged deuterium ion under the sample conditions would have acquired roughly 1.4x10^6/1.41 ms−1. If a detector was placed at a distance of 1 m, the ion flight times would be 1/1.4x10^6 and 1.41/1.4x10^6 s. Thus, the time of the ion arrival can be used to infer the ion type itself, if the evaporation time is known. From the above equation, it can be re-arranged to show that given a known flight distance. F, for the ion, and a known flight time, t, and thus one can substitute these values to obtain the mass-to-charge for the ion. Thus for an ion which traverses a 1 m flight path, across a time of 2000 ns, given an initial accelerating voltage of 5000 V (V in Si units is kg.m^2.s^-3.A^-1) and noting that one amu is 1×10−27 kg, the mass-to-charge ratio (more correctly the mass-to-ionisation value ratio) becomes ~3.86 amu/charge. The number of electrons removed, and thus net positive charge on the ion is not known directly, but can be inferred from the histogram (spectrum) of observed ions. Magnification The magnification in an atom is due to the projection of ions radially away from the small, sharp tip. Subsequently, in the far-field, the ions will be greatly magnified. This magnification is sufficient to observe field variations due to individual atoms, thus allowing in field ion and field evaporation modes for the imaging of single atoms. The standard projection model for the atom probe is an emitter geometry that is based upon a revolution of a conic section, such as a sphere, hyperboloid or paraboloid. For these tip models, solutions to the field may be approximated or obtained analytically. The magnification for a spherical emitter is inversely proportional to the radius of the tip, given a projection directly onto a spherical screen, the following equation can be obtained geometrically. Where rscreen is the radius of the detection screen from the tip centre, and rtip the tip radius. A practical tip to screen distances may range from several centimeters to several meters, with increased detector area required at larger to subtend the same field of view. Practically speaking, the usable magnification will be limited by several effects, such as lateral vibration of the atoms prior to evaporation. Whilst the magnification of both the field ion and atom probe microscopes is extremely high, the exact magnification is dependent upon conditions specific to the examined specimen, so unlike for conventional electron microscopes, there is often little direct control on magnification, and furthermore, obtained images may have strongly variable magnifications due to fluctuations in the shape of the electric field at the surface. Reconstruction The computational conversion of the ion sequence data, as obtained from a position-sensitive detector to a three-dimensional visualisation of atomic types, is termed "reconstruction". Reconstruction algorithms are typically geometrically based and have several literature formulations. Most models for reconstruction assume that the tip is a spherical object, and use empirical corrections to stereographic projection to convert detector positions back to a 2D surface embedded in 3D space, R3. By sweeping this surface through R3 as a function of the ion sequence input data, such as via ion-ordering, a volume is generated onto which positions the 2D detector positions can be computed and placed three-dimensional space. Typically the sweep takes the simple form of advancement of the surface, such that the surface is expanded in a symmetric manner about its advancement axis, with the advancement rate set by a volume attributed to each ion detected and identified. This causes the final reconstructed volume to assume a rounded-conical shape, similar to a badminton shuttlecock. The detected events thus become a point cloud data with attributed experimentally measured values, such as ion time of flight or experimentally derived quantities, e.g. time of flight or detector data. This form of data manipulation allows for rapid computer visualisation and analysis, with data presented as point cloud data with additional information, such as each ion's mass to charge (as computed from the velocity equation above), voltage or other auxiliary measured quantity or computation therefrom. Data features The canonical feature of atom probe data, is its high spatial resolution in the direction through the material, which has been attributed to an ordered evaporation sequence. This data can therefore image near atomically sharp buried interfaces with the associated chemical information. The data obtained from the evaporative process is however not without artefacts that form the physical evaporation or ionisation process. A key feature of the evaporation or field ion images is that the data density is highly inhomogeneous, due to the corrugation of the specimen surface at the atomic scale. This corrugation gives rise to strong electric field gradients in the near-tip zone (on the order of an atomic radii or less from the tip), which during ionisation deflects ions away from the electric field normal. The resultant deflection means that in these regions of high curvature, atomic terraces are belied by a strong anisotropy in the detection density. Where this occurs due to a few atoms on a surface is usually referred to as a "pole", as these are coincident with the crystallographic axes of the specimen (FCC, BCC, HCP) etc. Where the edges of an atomic terrace causes deflection, a low density line is formed and is termed a "zone line". These poles and zone-lines, whilst inducing fluctuations in data density in the reconstructed datasets, which can prove problematic during post-analysis, are critical for determining information such as angular magnification, as the crystallographic relationships between features are typically well known. When reconstructing the data, owing to the evaporation of successive layers of material from the sample, the lateral and in-depth reconstruction values are highly anisotropic. Determination of the exact resolution of the instrument is of limited use, as the resolution of the device is set by the physical properties of the material under analysis. Systems Many designs have been constructed since the method's inception. Initial field ion microscopes, precursors to modern atom probes, were usually glass blown devices developed by individual research laboratories. System layout At a minimum, an atom probe will consist of several key pieces of equipment. A vacuum system for maintaining the low pressures (~10−8 to 10−10 Pa) required, typically a classic 3 chambered UHV design. A system for the manipulation of samples inside the vacuum, including sample viewing systems. A cooling system to reduce atomic motion, such as a helium refrigeration circuit - providing sample temperatures as low as 15K. A high voltage system to raise the sample standing voltage near the threshold for field evaporation. A high voltage pulsing system, use to create timed field evaporation events A counter electrode that can be a simple disk shape (like the EIKOS™, or earlier generation atom probes), or a cone-shaped Local Electrode, like on a LEAP® system. The voltage pulse (negative) is typically applied to the counter electrode. A detection system for single energetic ions that includes XY position and TOF information. Optionally, an atom probe may also include laser-optical systems for laser beam targeting and pulsing, if using laser-evaporation methods. In-situ reaction systems, heaters, or plasma treatment may also be employed for some studies as well as a pure noble gas introduction for FIM. Performance Collectable ion volumes were previously limited to several thousand, or tens of thousands of ionic events. Subsequent electronics and instrumentation development has increased the rate of data accumulation, with datasets of hundreds of million atoms (dataset volumes of 107 nm3). Data collection times vary considerably depending upon the experimental conditions and the number of ions collected. Experiments take from a few minutes, to many hours to complete. Applications Metallurgy Atom probe has typically been employed in the chemical analysis of alloy systems at the atomic level. This has arisen as a result of voltage pulsed atom probes providing good chemical and sufficient spatial information in these materials. Metal samples from large grained alloys may be simple to fabricate, particularly from wire samples, with hand-electropolishing techniques giving good results. Subsequently, atom probe has been used in the analysis of the chemical composition of a wide range of alloys. Such data is critical in determining the effect of alloy constituents in a bulk material, identification of solid-state reaction features, such as solid phase precipitates. Such information may not be amenable to analysis by other means (e.g. TEM) owing to the difficulty in generating a three-dimensional dataset with composition. Semiconductors Semi-conductor materials are often analysable in atom probe, however sample preparation may be more difficult, and interpretation of results may be more complex, particularly if the semi-conductor contains phases which evaporate at differing electric field strengths. Applications such as ion implantation may be used to identify the distribution of dopants inside a semi-conducting material, which is increasingly critical in the correct design of modern nanometre scale electronics. Limitations Materials implicitly control achievable spatial resolution. Specimen geometry during the analysis is uncontrolled, yet controls projection behaviour, hence there is little control over the magnification. This induces distortions into the computer generated 3D dataset. Features of interest might evaporate in a physically different manner to the bulk sample, altering projection geometry and the magnification of the reconstructed volume. This yields strong spatial distortions in the final image. Volume selectability can be limited. Site specific preparation methods, e.g. using Focussed ion beam preparation, although more time-consuming, may be used to bypass such limitations. Ion overlap in some samples (e.g. between oxygen and sulfur) resulted in ambiguous analysed species. This may be mitigated by selection of experiment temperature or laser input energy to influence the ionisation number (+, ++, 3+ etc.) of the ionised groups. Data analysis can be used in some cases to statistically recover overlaps. Low molecular weight gases (Hydrogen & Helium) may be difficult to be removed from the analysis chamber, and may be adsorbed and emitted from the specimen, even though not present in the original specimen. This may also limit identification of Hydrogen in some samples. For this reason, deuterated samples have been used to overcome limitations. Results may be contingent on the parameters used to convert the 2D detected data into 3D. In more problematic materials, correct reconstruction may not be done, due to limited knowledge of the true magnification; particularly if zone or pole regions cannot be observed.

Amplifier figures of merit

In electronics, the figures of merit of an amplifier are numerical measures that characterize its properties and performance. Figures of merit can be given as a list of specifications that include properties such as gain, bandwidth, noise and linearity, among others listed in this article. Figures of merit are important for determining the suitability of a particular amplifier for an intended use. Gain The gain of an amplifier is the ratio of output to input power or amplitude, and is usually measured in decibels. When measured in decibels it is logarithmically related to the power ratio: G(dB)=10 log(Pout /Pin). RF amplifiers are often specified in terms of the maximum power gain obtainable, while the voltage gain of audio amplifiers and instrumentation amplifiers will be more often specified. For example, an audio amplifier with a gain given as 20 dB will have a voltage gain of ten. The use of voltage gain figure is appropriate when the amplifier's input impedance is much higher than the source impedance, and the load impedance higher than the amplifier's output impedance. If two equivalent amplifiers are being compared, the amplifier with higher gain settings would be more sensitive as it would take less input signal to produce a given amount of power. Bandwidth The bandwidth of an amplifier is the range of frequencies for which the amplifier gives "satisfactory performance". The definition of "satisfactory performance" may be different for different applications. However, a common and well-accepted metric is the half-power points (i.e. frequency where the power goes down by half its peak value) on the output vs. frequency curve. Therefore, bandwidth can be defined as the difference between the lower and upper half power points. This is therefore also known as the bandwidth. Bandwidths (otherwise called "frequency responses") for other response tolerances are sometimes quoted (, etc.) or "plus or minus 1dB" (roughly the sound level difference people usually can detect). The gain of a good quality full-range audio amplifier will be essentially flat between 20 Hz to about 20 kHz (the range of normal human hearing). In ultra-high-fidelity amplifier design, the amplifier's frequency response should extend considerably beyond this (one or more octaves either side) and might have points < 10 Hz and > . Professional touring amplifiers often have input and/or output filtering to sharply limit frequency response beyond ; too much of the amplifier's potential output power would otherwise be wasted on infrasonic and ultrasonic frequencies, and the danger of AM radio interference would increase. Modern switching amplifiers need steep low pass filtering at the output to get rid of high-frequency switching noise and harmonics. The range of frequency over which the gain is equal to or greater than 70.7% of its maximum gain is termed as bandwidth. Efficiency Efficiency is a measure of how much of the power source is usefully applied to the amplifier's output. Class A amplifiers are very inefficient, in the range of 10–20% with a max efficiency of 25% for direct coupling of the output. Inductive coupling of the output can raise their efficiency to a maximum of 50%. Drain efficiency is the ratio of output RF power to input DC power when primary input DC power has been fed to the drain of a field-effect transistor. Based on this definition, the drain efficiency cannot exceed 25% for a class A amplifier that is supplied drain bias current through resistors (because RF signal has its zero level at about 50% of the input DC). Manufacturers specify much higher drain efficiencies, and designers are able to obtain higher efficiencies by providing current to the drain of the transistor through an inductor or a transformer winding. In this case the RF zero level is near the DC rail and will swing both above and below the rail during operation. While the voltage level is above the DC rail current is supplied by the inductor. Class B amplifiers have a very high efficiency but are impractical for audio work because of high levels of distortion (See: Crossover distortion). In practical design, the result of a tradeoff is the class AB design. Modern Class AB amplifiers commonly have peak efficiencies between 30 and 55% in audio systems and 50-70% in radio frequency systems with a theoretical maximum of 78.5%. Commercially available Class D switching amplifiers have reported efficiencies as high as 90%. Amplifiers of Class C-F are usually known to be very high-efficiency amplifiers. RCA manufactured an AM broadcast transmitter employing a single class-C low-mu triode with an RF efficiency in the 90% range. More efficient amplifiers run cooler, and often do not need any cooling fans even in multi-kilowatt designs. The reason for this is that the loss of efficiency produces heat as a by-product of the energy lost during the conversion of power. In more efficient amplifiers there is less loss of energy so in turn less heat. In RF linear Power Amplifiers, such as cellular base stations and broadcast transmitters, special design techniques can be used to improve efficiency. Doherty designs, which use a second output stage as a "peak" amplifier, can lift efficiency from the typical 15% up to 30-35% in a narrow bandwidth. Envelope Tracking designs are able to achieve efficiencies of up to 60%, by modulating the supply voltage to the amplifier in line with the envelope of the signal. Linearity An ideal amplifier would be a totally linear device, but real amplifiers are only linear within limits. When the signal drive to the amplifier is increased, the output also increases until a point is reached where some part of the amplifier becomes saturated and cannot produce any more output; this is called clipping, and results in distortion. In most amplifiers a reduction in gain takes place before hard clipping occurs; the result is a compression effect, which (if the amplifier is an audio amplifier) sounds much less unpleasant to the ear. For these amplifiers, the 1 dB compression point is defined as the input power (or output power) where the gain is 1 dB less than the small signal gain. Sometimes this non linearity is deliberately designed in to reduce the audible unpleasantness of hard clipping under overload. Ill effects of non-linearity can be reduced with negative feedback. Linearization is an emergent field, and there are many techniques, such as feed forward, predistortion, postdistortion, in order to avoid the undesired effects of the non-linearities. Noise This is a measure of how much noise is introduced in the amplification process. Noise is an undesirable but inevitable product of the electronic devices and components; also, much noise results from intentional economies of manufacture and design time. The metric for noise performance of a circuit is noise figure or noise factor. Noise figure is a comparison between the output signal to noise ratio and the thermal noise of the input signal. Output dynamic range Output dynamic range is the range, usually given in dB, between the smallest and largest useful output levels. The lowest useful level is limited by output noise, while the largest is limited most often by distortion. The ratio of these two is quoted as the amplifier dynamic range. More precisely, if S = maximal allowed signal power and N = noise power, the dynamic range DR is DR = (S + N ) /N. In many switched mode amplifiers, dynamic range is limited by the minimum output step size. Slew rate Slew rate is the maximum rate of change of the output, usually quoted in volts per second (or microsecond). Many amplifiers are ultimately slew rate limited (typically by the impedance of a drive current having to overcome capacitive effects at some point in the circuit), which sometimes limits the full power bandwidth to frequencies well below the amplifier's small-signal frequency response. Rise time The rise time, tr, of an amplifier is the time taken for the output to change from 10% to 90% of its final level when driven by a step input. For a Gaussian response system (or a simple RC roll off), the rise time is approximated by: tr * BW = 0.35, where tr is rise time in seconds and BW is bandwidth in Hz. Settling time and ringing The time taken for the output to settle to within a certain percentage of the final value (for instance 0.1%) is called the settling time, and is usually specified for oscilloscope vertical amplifiers and high-accuracy measurement systems. Ringing refers to an output variation that cycles above and below an amplifier's final value and leads to a delay in reaching a stable output. Ringing is the result of overshoot caused by an underdamped circuit. Overshoot In response to a step input, the overshoot is the amount the output exceeds its final, steady-state value. Stability Stability is an issue in all amplifiers with feedback, whether that feedback is added intentionally or results unintentionally. It is especially an issue when applied over multiple amplifying stages. Stability is a major concern in RF and microwave amplifiers. The degree of an amplifier's stability can be quantified by a so-called stability factor. There are several different stability factors, such as the Stern stability factor and the Linvil stability factor, which specify a condition that must be met for the absolute stability of an amplifier in terms of its two-port parameters.

https://en.wikipedia.org/wiki/Acceptance%20testing

Acceptance testing

In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical tests, physical tests, or performance tests. In systems engineering, it may involve black-box testing performed on a system (for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products) prior to its delivery. In software testing, the ISTQB defines acceptance testing as: Acceptance testing is also known as user acceptance testing (UAT), end-user testing, operational acceptance testing (OAT), acceptance test-driven development (ATDD) or field (acceptance) testing. Acceptance criteria are the criteria that a system or component must satisfy in order to be accepted by a user, customer, or other authorized entity. Overview Testing is a set of activities conducted to facilitate discovery and/or evaluation of properties of one or more items under test. Each individual test, known as a test case, exercises a set of predefined test activities, developed to drive the execution of the test item to meet test objectives; including correct implementation, error identification, quality verification and other valued detail. The test environment is usually designed to be identical, or as close as possible, to the anticipated production environment. It includes all facilities, hardware, software, firmware, procedures and/or documentation intended for or used to perform the testing of software. UAT and OAT test cases are ideally derived in collaboration with business customers, business analysts, testers, and developers. It is essential that these tests include both business logic tests as well as operational environment conditions. The business customers (product owners) are the primary stakeholders of these tests. As the test conditions successfully achieve their acceptance criteria, the stakeholders are reassured the development is progressing in the right direction. User acceptance test (UAT) criteria (in agile software development) are usually created by business customers and expressed in a business domain language. These are high-level tests to verify the completeness of a user story or stories 'played' during any sprint/iteration. Operational acceptance test (OAT) criteria (regardless if using agile, iterative or sequential development) are defined in terms of functional and non-functional requirements; covering key quality attributes of functional stability, portability and reliability. Process The acceptance test suite may need to be performed multiple times, as all of the test cases may not be executed within a single test iteration. The acceptance test suite is run using predefined acceptance test procedures to direct the testers which data to use, the step-by-step processes to follow and the expected result following execution. The actual results are retained for comparison with the expected results. If the actual results match the expected results for each test case, the test case is said to pass. If the quantity of non-passing test cases does not breach the project's predetermined threshold, the test suite is said to pass. If it does, the system may either be rejected or accepted on conditions previously agreed between the sponsor and the manufacturer. The anticipated result of a successful test execution: test cases are executed, using predetermined data actual results are recorded actual and expected results are compared, and test results are determined. The objective is to provide confidence that the developed product meets both the functional and non-functional requirements. The purpose of conducting acceptance testing is that once completed, and provided the acceptance criteria are met, it is expected the sponsors will sign-off on the product development/enhancement as satisfying the defined requirements (previously agreed between business and product provider/developer). User acceptance testing User acceptance testing (UAT) consists of a process of verifying that a solution works for the user. It is not system testing (ensuring software does not crash and meets documented requirements) but rather ensures that the solution will work for the user (i.e. tests that the user accepts the solution); software vendors often refer to this as "Beta testing". This testing should be undertaken by the intended end user, or a subject-matter expert (SME), preferably the owner or client of the solution under test, and provide a summary of the findings for confirmation to proceed after trial or review. In software development, UAT as one of the final stages of a project often occurs before a client or customer accepts the new system. Users of the system perform tests in line with what would occur in real-life scenarios. It is important that the materials given to the tester be similar to the materials that the end user will have. Testers should be given real-life scenarios such as the three most common or difficult tasks that the users they represent will undertake. The UAT acts as a final verification of the required business functionality and proper functioning of the system, emulating real-world conditions on behalf of the paying client or a specific large customer. If the software works as required and without issues during normal use, one can reasonably extrapolate the same level of stability in production. User tests, usually performed by clients or by end-users, do not normally focus on identifying simple cosmetic problems such as spelling errors, nor on showstopper defects, such as software crashes; testers and developers identify and fix these issues during earlier unit testing, integration testing, and system testing phases. UAT should be executed against test scenarios. Test scenarios usually differ from System or Functional test cases in that they represent a "player" or "user" journey. The broad nature of the test scenario ensures that the focus is on the journey and not on technical or system-specific details, staying away from "click-by-click" test steps to allow for a variance in users' behaviour. Test scenarios can be broken down into logical "days", which are usually where the actor (player/customer/operator) or system (backoffice, front end) changes. In industry, a common UAT is a factory acceptance test (FAT). This test takes place before installation of the equipment. Most of the time testers not only check that the equipment meets the specification, but also that it is fully functional. A FAT usually includes a check of completeness, a verification against contractual requirements, a proof of functionality (either by simulation or a conventional function test) and a final inspection. The results of these tests give clients confidence in how the system will perform in production. There may also be legal or contractual requirements for acceptance of the system. Operational acceptance testing Operational acceptance testing (OAT) is used to conduct operational readiness (pre-release) of a product, service or system as part of a quality management system. OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. This type of testing focuses on the operational readiness of the system to be supported, and/or to become part of the production environment. Acceptance testing in extreme programming Acceptance testing is a term used in agile software development methodologies, particularly extreme programming, referring to the functional testing of a user story by the software development team during the implementation phase. The customer specifies scenarios to test when a user story has been correctly implemented. A story can have one or many acceptance tests, whatever it takes to ensure the functionality works. Acceptance tests are black-box system tests. Each acceptance test represents some expected result from the system. Customers are responsible for verifying the correctness of the acceptance tests and reviewing test scores to decide which failed tests are of highest priority. Acceptance tests are also used as regression tests prior to a production release. A user story is not considered complete until it has passed its acceptance tests. This means that new acceptance tests must be created for each iteration or the development team will report zero progress. Types of acceptance testing Typical types of acceptance testing include the following User acceptance testing This may include factory acceptance testing (FAT), i.e. the testing done by a vendor before the product or system is moved to its destination site, after which site acceptance testing (SAT) may be performed by the users at the site. Operational acceptance testingAlso known as operational readiness testing, this refers to the checking done to a system to ensure that processes and procedures are in place to allow the system to be used and maintained. This may include checks done to back-up facilities, procedures for disaster recovery, training for end users, maintenance procedures, and security procedures. Contract and regulation acceptance testing In contract acceptance testing, a system is tested against acceptance criteria as documented in a contract, before the system is accepted. In regulation acceptance testing, a system is tested to ensure it meets governmental, legal and safety standards. Factory acceptance testing Acceptance testing conducted at the site at which the product is developed and performed by employees of the supplier organization, to determine whether a component or system satisfies the requirements, normally including hardware as well as software. Alpha and beta testing Alpha testing takes place at developers' sites, and involves testing of the operational system by internal staff, before it is released to external customers. Beta testing takes place at customers' sites, and involves testing by a group of customers who use the system at their own locations and provide feedback, before the system is released to other customers. The latter is often called "field testing". Acceptance criteria According to the Project Management Institute, acceptance criteria is a "set of conditions that is required to be met before deliverables are accepted." Requirements found in acceptance criteria for a given component of the system are usually very detailed.

https://en.wikipedia.org/wiki/Amygdalin

Amygdalin

Amygdalin (from Ancient Greek: 'almond') is a naturally occurring chemical compound found in many plants, most notably in the seeds (kernels) of apricots, bitter almonds, apples, peaches, cherries and plums, and in the roots of manioc. Amygdalin is classified as a cyanogenic glycoside, because each amygdalin molecule includes a nitrile group, which can be released as the toxic cyanide anion by the action of a beta-glucosidase. Eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning. Since the early 1950s, both amygdalin and a chemical derivative named laetrile have been promoted as alternative cancer treatments, often under the misnomer vitamin B17 (neither amygdalin nor laetrile is a vitamin). Scientific study has found them to not only be clinically ineffective in treating cancer, but also potentially toxic or lethal when taken by mouth due to cyanide poisoning. The promotion of laetrile to treat cancer has been described in the medical literature as a canonical example of quackery, and as "the slickest, most sophisticated, and certainly the most remunerative cancer quack promotion in medical history". Chemistry Amygdalin is a cyanogenic glycoside derived from the aromatic amino acid phenylalanine. Amygdalin and prunasin are common among plants of the family Rosaceae, particularly the genus Prunus, Poaceae (grasses), Fabaceae (legumes), and in other food plants, including flaxseed and manioc. Within these plants, amygdalin and the enzymes necessary to hydrolyze it are stored in separate locations, and only mix as a result of tissue damage. This provides a natural defense system. Amygdalin is contained in stone fruit kernels, such as almonds, apricot (14 g/kg), peach (6.8 g/kg), and plum (4–17.5 g/kg depending on variety), and also in the seeds of the apple (3 g/kg). Benzaldehyde released from amygdalin provides a bitter flavor. Because of a difference in a recessive gene called Sweet kernal [Sk], much less amygdalin is present in nonbitter (or sweet) almond than bitter almond. In one study, bitter almond amygdalin concentrations ranged from 33 to 54 g/kg depending on variety; semibitter varieties averaged 1 g/kg and sweet varieties averaged 0.063 g/kg with significant variability based on variety and growing region. For one method of isolating amygdalin, the stones are removed from the fruit and cracked to obtain the kernels, which are dried in the sun or in ovens. The kernels are boiled in ethanol; on evaporation of the solution and the addition of diethyl ether, amygdalin is precipitated as minute white crystals. Natural amygdalin has the (R)-configuration at the chiral phenyl center. Under mild basic conditions, this stereogenic center isomerizes; the (S)-epimer is called neoamygdalin. Although the synthesized version of amygdalin is the (R)-epimer, the stereogenic center attached to the nitrile and phenyl groups easily epimerizes if the manufacturer does not store the compound correctly. Amygdalin is hydrolyzed by intestinal β-glucosidase (emulsin) and amygdalin beta-glucosidase (amygdalase) to give gentiobiose and L-mandelonitrile. Gentiobiose is further hydrolyzed to give glucose, whereas mandelonitrile (the cyanohydrin of benzaldehyde) decomposes to give benzaldehyde and hydrogen cyanide. Hydrogen cyanide in sufficient quantities (allowable daily intake: ~0.6 mg) causes cyanide poisoning which has a fatal oral dose range of 0.6–1.5 mg/kg of body weight. Laetrile Laetrile (patented 1961) is a simpler semisynthetic derivative of amygdalin. Laetrile is synthesized from amygdalin by hydrolysis. The usual preferred commercial source is from apricot kernels (Prunus armeniaca). The name is derived from the separate words "laevorotatory" and "mandelonitrile". Laevorotatory describes the stereochemistry of the molecule, while mandelonitrile refers to the portion of the molecule from which cyanide is released by decomposition. A 500 mg laetrile tablet may contain between 2.5 and 25 mg of hydrogen cyanide. Like amygdalin, laetrile is hydrolyzed in the duodenum (alkaline) and in the intestine (enzymatically) to D-glucuronic acid and L-mandelonitrile; the latter hydrolyzes to benzaldehyde and hydrogen cyanide, that in sufficient quantities causes cyanide poisoning. Claims for laetrile were based on three different hypotheses: The first hypothesis proposed that cancerous cells contained copious beta-glucosidases, which release HCN from laetrile via hydrolysis. Normal cells were reportedly unaffected, because they contained low concentrations of beta-glucosidases and high concentrations of rhodanese, which converts HCN to the less toxic thiocyanate. Later, however, it was shown that both cancerous and normal cells contain only trace amounts of beta-glucosidases and similar amounts of rhodanese. The second proposed that, after ingestion, amygdalin was hydrolyzed to mandelonitrile, transported intact to the liver and converted to a beta-glucuronide complex, which was then carried to the cancerous cells, hydrolyzed by beta-glucuronidases to release mandelonitrile and then HCN. Mandelonitrile, however, dissociates to benzaldehyde and hydrogen cyanide, and cannot be stabilized by glycosylation. Finally, the third asserted that laetrile is the discovered vitamin B-17, and further suggests that cancer is a result of "B-17 deficiency". It postulated that regular dietary administration of this form of laetrile would, therefore, actually prevent all incidences of cancer. There is no evidence supporting this conjecture in the form of a physiologic process, nutritional requirement, or identification of any deficiency syndrome. The term "vitamin B-17" is not recognized by Committee on Nomenclature of the American Institute of Nutrition Vitamins. Ernst T. Krebs (not to be confused with Hans Adolf Krebs, the discoverer of the citric acid cycle) branded laetrile as a vitamin in order to have it classified as a nutritional supplement rather than as a pharmaceutical. History of laetrile Early usage Amygdalin was first isolated in 1830 from bitter almond seeds (Prunus dulcis) by Pierre-Jean Robiquet and Antoine Boutron-Charlard. Liebig and Wöhler found three hydrolysis products of amygdalin: sugar, benzaldehyde, and prussic acid (hydrogen cyanide, HCN). Later research showed that sulfuric acid hydrolyzes it into D-glucose, benzaldehyde, and prussic acid; while hydrochloric acid gives mandelic acid, D-glucose, and ammonia. In 1845 amygdalin was used as a cancer treatment in Russia, and in the 1920s in the United States, but it was considered too poisonous. In the 1950s, a purportedly non-toxic, synthetic form was patented for use as a meat preservative, and later marketed as laetrile for cancer treatment. The U.S. Food and Drug Administration prohibited the interstate shipment of amygdalin and laetrile in 1977. Thereafter, 27 U.S. states legalized the use of amygdalin within those states. Subsequent results In a 1977 controlled, blinded trial, laetrile showed no more activity than placebo. Subsequently, laetrile was tested on 14 tumor systems without evidence of effectiveness. The Memorial Sloan–Kettering Cancer Center (MSKCC) concluded that "laetrile showed no beneficial effects." Mistakes in an earlier MSKCC press release were highlighted by a group of laetrile proponents led by Ralph Moss, former public affairs official of MSKCC who had been fired following his appearance at a press conference accusing the hospital of covering up the benefits of laetrile. These mistakes were considered scientifically inconsequential, but Nicholas Wade in Science stated that "even the appearance of a departure from strict objectivity is unfortunate." The results from these studies were published all together. A 2015 systematic review from the Cochrane Collaboration found: The authors also recommended, on ethical and scientific grounds, that no further clinical research into laetrile or amygdalin be conducted. Given the lack of evidence, laetrile has not been approved by the U.S. Food and Drug Administration or the European Commission. The U.S. National Institutes of Health evaluated the evidence separately and concluded that clinical trials of amygdalin showed little or no effect against cancer. For example, a 1982 trial by the Mayo Clinic of 175 patients found that tumor size had increased in all but one patient. The authors reported that "the hazards of amygdalin therapy were evidenced in several patients by symptoms of cyanide toxicity or by blood cyanide levels approaching the lethal range." The study concluded "Patients exposed to this agent should be instructed about the danger of cyanide poisoning, and their blood cyanide levels should be carefully monitored. Amygdalin (Laetrile) is a toxic drug that is not effective as a cancer treatment". Additionally, "No controlled clinical trials (trials that compare groups of patients who receive the new treatment to groups who do not) of laetrile have been reported." The side effects of laetrile treatment are the symptoms of cyanide poisoning. These symptoms include: nausea and vomiting, headache, dizziness, cherry red skin color, liver damage, abnormally low blood pressure, droopy upper eyelid, trouble walking due to damaged nerves, fever, mental confusion, coma, and death. The European Food Safety Agency's Panel on Contaminants in the Food Chain has studied the potential toxicity of the amygdalin in apricot kernels. The Panel reported, "If consumers follow the recommendations of websites that promote consumption of apricot kernels, their exposure to cyanide will greatly exceed" the dose expected to be toxic. The Panel also reported that acute cyanide toxicity had occurred in adults who had consumed 20 or more kernels and that in children "five or more kernels appear to be toxic". Advocacy and legality of laetrile Advocates for laetrile assert that there is a conspiracy between the US Food and Drug Administration, the pharmaceutical industry and the medical community, including the American Medical Association and the American Cancer Society, to exploit the American people, and especially cancer patients. Advocates of the use of laetrile have also changed the rationale for its use, first as a treatment of cancer, then as a vitamin, then as part of a "holistic" nutritional regimen, or as treatment for cancer pain, among others, none of which have any significant evidence supporting its use. Despite the lack of evidence for its use, laetrile developed a significant following due to its wide promotion as a "pain-free" treatment of cancer as an alternative to surgery and chemotherapy that have significant side effects. The use of laetrile led to a number of deaths. The FDA and AMA crackdown, begun in the 1970s, effectively escalated prices on the black market, played into the conspiracy narrative and enabled unscrupulous profiteers to foster multimillion-dollar smuggling empires. Some American cancer patients have traveled to Mexico for treatment with the substance, for example at the Oasis of Hope Hospital in Tijuana. The actor Steve McQueen died in Mexico following surgery to remove a stomach tumor, having previously undergone extended treatment for pleural mesothelioma (a cancer associated with asbestos exposure) under the care of William D. Kelley, a de-licensed dentist and orthodontist who claimed to have devised a cancer treatment involving pancreatic enzymes, 50 daily vitamins and minerals, frequent body shampoos, enemas, and a specific diet as well as laetrile. Laetrile advocates in the United States include Dean Burk, a former chief chemist of the National Cancer Institute cytochemistry laboratory, and national arm wrestling champion Jason Vale, who falsely claimed that his kidney and pancreatic cancers were cured by eating apricot seeds. Vale was convicted in 2004 for, among other things, fraudulently marketing laetrile as a cancer cure. The court also found that Vale had made at least $500,000 from his fraudulent sales of laetrile. In the 1970s, court cases in several states challenged the FDA's authority to restrict access to what they claimed are potentially lifesaving drugs. More than twenty states passed laws making the use of laetrile legal. After the unanimous Supreme Court ruling in United States v. Rutherford which established that interstate transport of the compound was illegal, usage fell off dramatically. The US Food and Drug Administration continues to seek jail sentences for vendors marketing laetrile for cancer treatment, calling it a "highly toxic product that has not shown any effect on treating cancer." In popular culture The Law & Order episode "Second Opinion" is about a nutritional counselor named "Doctor" Haas giving patients laetrile as a cancer treatment for breast cancer as an alternative to getting a mastectomy.

Acid rain

Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life-forms. In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation. Acid rain is also capable of detrimenting soil composition by stripping it of nutrients such as calcium and magnesium which play a role in plant growth and maintaining healthy soil. In terms of human infrastructure, acid rain also causes paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health. Some governments, including those in Europe and North America, have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere through air pollution regulations. These efforts have had positive results due to the widespread research on acid rain starting in the 1960s and the publicized information on its harmful effects. The main source of sulfur and nitrogen compounds that result in acid rain are anthropogenic, but nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions. Definition "Acid rain" is a popular term referring to the deposition of a mixture from wet (rain, snow, sleet, fog, cloudwater, and dew) and dry (acidifying particles and gases) acidic components. Distilled water, once carbon dioxide is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline. "Clean" or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid according to the following reaction: Carbonic acid then can ionize in water forming low concentrations of carbonate and hydronium ions: Unpolluted rain can also contain other chemicals which affect its pH (acidity level). A common example is nitric acid produced by electric discharge in the atmosphere such as lightning. Acid deposition as an environmental issue (discussed later in the article) would include additional acids other than . Occasional pH readings in rain and fog water of well below 2.4 have been reported in industrialized areas. The main sources of the SO2 and NOx pollution that causes acid rain are burning fossil fuels to generate electricity and power internal combustion vehicles, to refine oil, and in industrial manufacturing and other processes. History Acid rain was first systematically studied in Europe, in the 1960s, and in the United States and Canada, the following decade. In Europe The corrosive effect of polluted, acidic city air on limestone and marble was noted in the 17th century by John Evelyn, who remarked upon the poor condition of the Arundel marbles. Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides into the atmosphere have increased. In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England. Smith coined the term "acid rain" in 1872. In the late 1960s, scientists began widely observing and studying the phenomenon. At first, the main focus in this research lay on local effects of acid rain. Waldemar Christofer Brøgger was the first to acknowledge long-distance transportation of pollutants crossing borders from the United Kingdom to Norway – a problem systematically studied by Brynjulf Ottar in the 1970s. Ottar's work was strongly influenced by Swedish soil scientist Svante Odén, who had drawn widespread attention to Europe's acid rain problem in popular newspapers and wrote a landmark paper on the subject in 1968. In the United States The earliest report about acid rain in the United States came from chemical evidence gathered from Hubbard Brook Valley; public awareness of acid rain in the US increased in the 1970s after The New York Times reported on these findings. In 1972, a group of scientists including Gene Likens discovered the rain that was deposited at White Mountains of New Hampshire was acidic. The pH of the sample was measured to be 4.03 at Hubbard Brook. The Hubbard Brook Ecosystem Study followed up with a series of research studies that analyzed the environmental effects of acid rain. Acid rain that mixed with stream water at Hubbard Brook was neutralized by the alumina from soils. The result of this research indicated that the chemical reaction between acid rain and aluminium leads to an increasing rate of soil weathering. Experimental research was done to examine the effects of increased acidity in streams on ecological species. In 1980, a group of scientists modified the acidity of Norris Brook, New Hampshire, and observed the change in species' behaviors. There was a decrease in species diversity, an increase in community dominants, and a decrease in the food web complexity. In 1980, the US Congress passed an Acid Deposition Act. This Act established an 18-year assessment and research program under the direction of the National Acidic Precipitation Assessment Program (NAPAP). NAPAP enlarged a network of monitoring sites to determine how acidic the precipitation actually was, seeking to determine long-term trends, and established a network for dry deposition. Using a statistically based sampling design, NAPAP quantified the effects of acid rain on a regional basis by targeting research and surveys to identify and quantify the effects of acid precipitation on freshwater and terrestrial ecosystems. NAPAP also assessed the effects of acid rain on historical buildings, monuments, and building materials. It also funded extensive studies on atmospheric processes and potential control programs. From the start, policy advocates from all sides attempted to influence NAPAP activities to support their particular policy advocacy efforts, or to disparage those of their opponents. For the US Government's scientific enterprise, a significant impact of NAPAP were lessons learned in the assessment process and in environmental research management to a relatively large group of scientists, program managers, and the public. In 1981, the National Academy of Sciences was looking into research about the controversial issues regarding acid rain. President Ronald Reagan dismissed the issues of acid rain until his personal visit to Canada and confirmed that the Canadian border suffered from the drifting pollution from smokestacks originating in the US Midwest. Reagan honored the agreement to Canadian Prime Minister Pierre Trudeau's enforcement of anti-pollution regulation. In 1982, Reagan commissioned William Nierenberg to serve on the National Science Board. Nierenberg selected scientists including Gene Likens to serve on a panel to draft a report on acid rain. In 1983, the panel of scientists came up with a draft report, which concluded that acid rain is a real problem and solutions should be sought. White House Office of Science and Technology Policy reviewed the draft report and sent Fred Singer's suggestions of the report, which cast doubt on the cause of acid rain. The panelists revealed rejections against Singer's positions and submitted the report to Nierenberg in April. In May 1983, the House of Representatives voted against legislation that aimed to control sulfur emissions. There was a debate about whether Nierenberg delayed to release the report. Nierenberg himself denied the saying about his suppression of the report and stated that the report was withheld after the House's vote because it was not ready to be published. In 1991, the US National Acid Precipitation Assessment Program (NAPAP) provided its first assessment of acid rain in the United States. It reported that 5% of New England Lakes were acidic, with sulfates being the most common problem. They noted that 2% of the lakes could no longer support Brook Trout, and 6% of the lakes were unsuitable for the survival of many species of minnow. Subsequent Reports to Congress have documented chemical changes in soil and freshwater ecosystems, nitrogen saturation, decreases in amounts of nutrients in soil, episodic acidification, regional haze, and damage to historical monuments. Meanwhile, in 1990, the US Congress passed a series of amendments to the Clean Air Act. Title IV of these amendments established a cap and trade system designed to control emissions of sulfur dioxide and nitrogen oxides. Both these emissions proved to cause a significant problem on U.S. citizens and their access to healthy clean air. Title IV called for a total reduction of about 10 million tons of SO2 emissions from power plants, close to a 50% reduction. It was implemented in two phases. Phase I began in 1995, and limited sulfur dioxide emissions from 110 of the largest power plants to a combined total of 8.7 million tons of sulfur dioxide. One power plant in New England (Merrimack) was in Phase I. Four other plants (Newington, Mount Tom, Brayton Point, and Salem Harbor) were added under other provisions of the program. Phase II began in 2000, and affects most of the power plants in the country. During the 1990s, research continued. On March 10, 2005, the EPA issued the Clean Air Interstate Rule (CAIR). This rule provides states with a solution to the problem of power plant pollution that drifts from one state to another. CAIR will permanently cap emissions of SO2 and NOx in the eastern United States. When fully implemented, CAIR will reduce SO2 emissions in 28 eastern states and the District of Columbia by over 70% and NOx emissions by over 60% from 2003 levels. Overall, the program's cap and trade program has been successful in achieving its goals. Since the 1990s, SO2 emissions have dropped 40%, and according to the Pacific Research Institute, acid rain levels have dropped 65% since 1976. Conventional regulation was used in the European Union, which saw a decrease of over 70% in SO2 emissions during the same time period. In 2007, total SO2 emissions were 8.9 million tons, achieving the program's long-term goal ahead of the 2010 statutory deadline. In 2007 the EPA estimated that by 2010, the overall costs of complying with the program for businesses and consumers would be $1 billion to $2 billion a year, only one fourth of what was originally predicted. Forbes says: "In 2010, by which time the cap and trade system had been augmented by the George W. Bush administration's Clean Air Interstate Rule, SO2 emissions had fallen to 5.1 million tons." The term citizen science can be traced back as far as January 1989 to a campaign by the Audubon Society to measure acid rain. Scientist Muki Haklay cites in a policy report for the Wilson Center entitled 'Citizen Science and Policy: A European Perspective' a first use of the term 'citizen science' by R. Kerson in the magazine MIT Technology Review from January 1989. Quoting from the Wilson Center report: "The new form of engagement in science received the name "citizen science". The first recorded example of the use of the term is from 1989, describing how 225 volunteers across the US collected rain samples to assist the Audubon Society in an acid-rain awareness raising campaign. The volunteers collected samples, checked for acidity, and reported back to the organization. The information was then used to demonstrate the full extent of the phenomenon." In Canada Canadian Harold Harvey was among the first to research a "dead" lake. In 1971, he and R. J. Beamish published a report, "Acidification of the La Cloche Mountain Lakes", documenting the gradual deterioration of fish stocks in 60 lakes in Killarney Park in Ontario, which they had been studying systematically since 1966. In the 1970s and 80s, acid rain was a major topic of research at the Experimental Lakes Area (ELA) in Northwestern Ontario, Canada. Researchers added sulfuric acid to whole lakes in controlled ecosystem experiments to simulate the effects of acid rain. Because its remote conditions allowed for whole-ecosystem experiments, research at the ELA showed that the effect of acid rain on fish populations started at concentrations much lower than those observed in laboratory experiments. In the context of a food web, fish populations crashed earlier than when acid rain had direct toxic effects to the fish because the acidity led to crashes in prey populations (e.g. mysids). As experimental acid inputs were reduced, fish populations and lake ecosystems recovered at least partially, although invertebrate populations have still not completely returned to the baseline conditions. This research showed both that acidification was linked to declining fish populations and that the effects could be reversed if sulfuric acid emissions decreased, and influenced policy in Canada and the United States. In 1985, seven Canadian provinces (all except British Columbia, Alberta, and Saskatchewan) and the federal government signed the Eastern Canada Acid Rain Program. The provinces agreed to limit their combined sulfur dioxide emissions to 2.3 million tonnes by 1994. The Canada-US Air Quality Agreement was signed in 1991. In 1998, all federal, provincial, and territorial Ministers of Energy and Environment signed The Canada-Wide Acid Rain Strategy for Post-2000, which was designed to protect lakes that are more sensitive than those protected by earlier policies. Emissions of chemicals leading to acidification The most important gas which leads to acidification is sulfur dioxide. Emissions of nitrogen oxides which are oxidized to form nitric acid are of increasing importance due to stricter controls on emissions of sulfur compounds. 70 Tg(S) per year in the form of SO2 comes from fossil fuel combustion and industry, 2.8 Tg(S) from wildfires, and 7–8 Tg(S) per year from volcanoes. Natural phenomena The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes. Thus, for example, fumaroles from the Laguna Caliente crater of Poás Volcano create extremely high amounts of acid rain and fog, with acidity as high as a pH of 2, clearing an area of any vegetation and frequently causing irritation to the eyes and lungs of inhabitants in nearby settlements. Acid-producing gasses are also created by biological processes that occur on the land, in wetlands, and in the oceans. The major biological source of sulfur compounds is dimethyl sulfide. Nitric acid in rainwater is an important source of fixed nitrogen for plant life, and is also produced by electrical activity in the atmosphere such as lightning. Acidic deposits have been detected in glacial ice thousands of years old in remote parts of the globe. Human activity The principal cause of acid rain is sulfur and nitrogen compounds from human sources, such as electricity generation, animal agriculture, factories, and motor vehicles. These also include power plants, which use electric power generators that account for a quarter of nitrogen oxides and two-thirds of sulfur dioxide within the atmosphere. Industrial acid rain is a substantial problem in China and Russia and areas downwind from them. These areas all burn sulfur-containing coal to generate heat and electricity. The problem of acid rain has not only increased with population and industrial growth, but has become more widespread. The use of tall smokestacks to reduce local pollution has contributed to the spread of acid rain by releasing gases into regional atmospheric circulation; dispersal from these taller stacks causes pollutants to be carried farther, causing widespread ecological damage. Often deposition occurs a considerable distance downwind of the emissions, with mountainous regions tending to receive the greatest deposition (because of their higher rainfall). An example of this effect is the low pH of rain which falls in Scandinavia. Regarding low pH and pH imbalances in correlation to acid rain, low levels, or those under the pH value of 7, are considered acidic. Acid rain falls at a pH value of roughly 4, making it harmful to consume for humans. When these low pH levels fall in specific regions, they not only affect the environment but also human health. With acidic pH levels in humans comes hair loss, low urinary pH, severe mineral imbalances, constipation, and many cases of chronic disorders like Fibromyalgia and Basal Carcinoma. Chemical process Combustion of fuels produces sulfur dioxide and nitric oxides. They are converted into sulfuric acid and nitric acid. Gas phase chemistry In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via an intermolecular reaction: SO2 + OH· → HOSO2· which is followed by: HOSO2· + O2 → HO2· + SO3 In the presence of water, sulfur trioxide (SO3) is converted rapidly to sulfuric acid: SO3 (g) + H2O (l) → H2SO4 (aq) Nitrogen dioxide reacts with OH to form nitric acid: NO2 + OH· → HNO3 Chemistry in cloud droplets When clouds are present, the loss rate of SO2 is faster than can be explained by gas phase chemistry alone. This is due to reactions in the liquid water droplets. Hydrolysis Sulfur dioxide dissolves in water and then, like carbon dioxide, hydrolyses in a series of equilibrium reactions: SO2 (g) + H2O SO2·H2O SO2·H2O H+ + HSO3− HSO3− H+ + SO32− Oxidation There are a large number of aqueous reactions that oxidize sulfur from S(IV) to S(VI), leading to the formation of sulfuric acid. The most important oxidation reactions are with ozone, hydrogen peroxide and oxygen (reactions with oxygen are catalyzed by iron and manganese in the cloud droplets). Acid deposition Wet deposition Wet deposition of acids occurs when any form of precipitation (rain, snow, and so on) removes acids from the atmosphere and delivers it to the Earth's surface. This can result from the deposition of acids produced in the raindrops (see aqueous phase chemistry above) or by the precipitation removing the acids either in clouds or below clouds. Wet removal of both gases and aerosols are both of importance for wet deposition. Dry deposition Acid deposition also occurs via dry deposition in the absence of precipitation. This can be responsible for as much as 20 to 60% of total acid deposition. This occurs when particles and gases stick to the ground, plants or other surfaces. Adverse effects Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms as well as causing damage to buildings and having impacts on human health. Surface waters and aquatic animals Both the lower pH and higher aluminium concentrations in surface water that occur as a result of acid rain can cause damage to fish and other aquatic animals. At pH lower than 5 most fish eggs will not hatch and lower pH can kill adult fish. As lakes and rivers become more acidic biodiversity is reduced. Acid rain has eliminated insect life and some fish species, including the brook trout in some lakes, streams, and creeks in geographically sensitive areas, such as the Adirondack Mountains of the United States. However, the extent to which acid rain contributes directly or indirectly via runoff from the catchment to lake and river acidity (i.e., depending on characteristics of the surrounding watershed) is variable. The United States Environmental Protection Agency's (EPA) website states: "Of the lakes and streams surveyed, acid rain caused acidity in 75% of the acidic lakes and about 50% of the acidic streams". Lakes hosted by silicate basement rocks are more acidic than lakes within limestone or other basement rocks with a carbonate composition (i.e. marble) due to buffering effects by carbonate minerals, even with the same amount of acid rain. Soils Soil biology and chemistry can be seriously damaged by acid rain. Some microbes are unable to tolerate changes to low pH and are killed. The enzymes of these microbes are denatured (changed in shape so they no longer function) by the acid. The hydronium ions of acid rain also mobilize toxins, such as aluminium, and leach away essential nutrients and minerals such as magnesium. 2 H+ (aq) + Mg2+ (clay) 2 H+ (clay) + Mg2+ (aq) Soil chemistry can be dramatically changed when base cations, such as calcium and magnesium, are leached by acid rain, thereby affecting sensitive species, such as sugar maple (Acer saccharum). Soil acidification Impacts of acidic water and soil acidification on plants could be minor or in most cases major. Most minor cases which do not result in fatality of plant life can be attributed to the plants being less susceptible to acidic conditions and/or the acid rain being less potent. However, even in minor cases, the plant will eventually die due to the acidic water lowering the plant's natural pH. Acidic water enters the plant and causes important plant minerals to dissolve and get carried away; which ultimately causes the plant to die of lack of minerals for nutrition. In major cases, which are more extreme, the same process of damage occurs as in minor cases, which is removal of essential minerals, but at a much quicker rate. Likewise, acid rain that falls on soil and on plant leaves causes drying of the waxy leaf cuticle, which ultimately causes rapid water loss from the plant to the outside atmosphere and eventually results in death of the plant. To see if a plant is being affected by soil acidification, one can closely observe the plant leaves. If the leaves are green and look healthy, the soil pH is normal and acceptable for plant life. But if the plant leaves have yellowing between the veins on their leaves, that means the plant is suffering from acidification and is unhealthy. Moreover, a plant suffering from soil acidification cannot photosynthesize; the acid-water-induced process of drying out of the plant can destroy chloroplast organelles. Without being able to photosynthesize, a plant cannot create nutrients for its own survival or oxygen for the survival of aerobic organisms, which affects most species on Earth and ultimately ends the purpose of the plant's existence. Forests and other vegetation Adverse effects may be indirectly related to acid rain, like the acid's effects on soil (see above) or high concentration of gaseous precursors to acid rain. High altitude forests are especially vulnerable as they are often surrounded by clouds and fog which are more acidic than rain. Other plants can also be damaged by acid rain, but the effect on food crops is minimized by the application of lime and fertilizers to replace lost nutrients. In cultivated areas, limestone may also be added to increase the ability of the soil to keep the pH stable, but this tactic is largely unusable in the case of wilderness lands. When calcium is leached from the needles of red spruce, these trees become less cold tolerant and exhibit winter injury and even death. Ocean acidification Acid rain has a much less harmful effect on oceans on a global scale, but it creates an amplified impact in the shallower waters of coastal waters. Acid rain can cause the ocean's pH to fall, known as ocean acidification, making it more difficult for different coastal species to create their exoskeletons that they need to survive. These coastal species link together as part of the ocean's food chain, and without them being a source for other marine life to feed off of, more marine life will die. Coral's limestone skeleton is particularly sensitive to pH decreases, because the calcium carbonate, a core component of the limestone skeleton, dissolves in acidic (low pH) solutions. In addition to acidification, excess nitrogen inputs from the atmosphere promote increased growth of phytoplankton and other marine plants, which, in turn, may cause more frequent harmful algal blooms and eutrophication (the creation of oxygen-depleted "dead zones") in some parts of the ocean. Human health effects Acid rain does not directly affect human health. The acid in the rainwater is too dilute to have direct adverse effects. The particulates responsible for acid rain (sulfur dioxide and nitrogen oxides) do have an adverse effect. These particulates come together and react in the atmosphere, forming nitrate particles and fine sulfate. Increased amounts of fine particulate matter in the air contribute to heart and lung problems, including asthma and bronchitis. These particular effects on the heart and lungs can alter their function, including heart attack caused death for those with an increased risk of heart disease and other heart conditions. Other adverse effects Acid rain can damage buildings, historic monuments, and statues, especially those made of rocks, such as limestone and marble, that contain large amounts of calcium carbonate. Acids in the rain react with the calcium compounds in the stones to create gypsum, which then flakes off. CaCO3 (s) + H2SO4 (aq) CaSO4 (s) + CO2 (g) + H2O (l) The effects of this are commonly seen on old gravestones, where acid rain can cause the inscriptions to become completely illegible. Acid rain also increases the corrosion rate of metals, in particular iron, steel, copper and bronze. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States, and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan. Prevention methods Technical solutions Many coal-firing power stations use flue-gas desulfurization (FGD) to remove sulfur-containing gases from their stack gases. For a typical coal-fired power station, FGD will remove 95% or more of the SO2 in the flue gases. An example of FGD is the wet scrubber which is commonly used. A wet scrubber is basically a reaction tower equipped with a fan that extracts hot smoke stack gases from a power plant into the tower. Lime or limestone in slurry form is also injected into the tower to mix with the stack gases and combine with the sulfur dioxide present. The calcium carbonate of the limestone produces pH-neutral calcium sulfate that is physically removed from the scrubber. That is, the scrubber turns sulfur pollution into industrial sulfates. In some areas the sulfates are sold to chemical companies as gypsum when the purity of calcium sulfate is high. In others, they are placed in landfill. The effects of acid rain can last for generations, as the effects of pH level change can stimulate the continued leaching of undesirable chemicals into otherwise pristine water sources, killing off vulnerable insect and fish species and blocking efforts to restore native life. Fluidized bed combustion also reduces the amount of sulfur emitted by power production. Vehicle emissions control reduces emissions of nitrogen oxides from motor vehicles. International treaties International treaties on the long-range transport of atmospheric pollutants have been agreed upon by western countries for some time now. Beginning in 1979, European countries convened in order to ratify general principles discussed during the UNECE Convention. The purpose was to combat Long-Range Transboundary Air Pollution. The 1985 Helsinki Protocol on the Reduction of Sulfur Emissions under the Convention on Long-Range Transboundary Air Pollution furthered the results of the convention. Results of the treaty have already come to fruition, as evidenced by an approximate 40 percent drop in particulate matter in North America. The effectiveness of the Convention in combatting acid rain has inspired further acts of international commitment to prevent the proliferation of particulate matter. Canada and the US signed the Air Quality Agreement in 1991. Most European countries and Canada signed the treaties. Activity of the Long-Range Transboundary Air Pollution Convention remained dormant after 1999, when 27 countries convened to further reduce the effects of acid rain. In 2000, foreign cooperation to prevent acid rain was sparked in Asia for the first time. Ten diplomats from countries ranging throughout the continent convened to discuss ways to prevent acid rain. Following these discussions, the Acid Deposition Monitoring Network in East Asia (EANET) was established in 2001 as an intergovernmental initiative to provide science-based inputs for decision makers and promote international cooperation on acid deposition in East Asia. In 2023, the EANET member countries include Cambodia, China, Indonesia, Japan, Lao PDR, Malaysia, Mongolia, Myanmar, the Philippines, Republic of Korea, Russia, Thailand and Vietnam. Emissions trading In this regulatory scheme, every current polluting facility is given or may purchase on an open market an emissions allowance for each unit of a designated pollutant it emits. Operators can then install pollution control equipment, and sell portions of their emissions allowances they no longer need for their own operations, thereby recovering some of the capital cost of their investment in such equipment. The intention is to give operators economic incentives to install pollution controls. The first emissions trading market was established in the United States by enactment of the Clean Air Act Amendments of 1990. The overall goal of the Acid Rain Program established by the Act is to achieve significant environmental and public health benefits through reductions in emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx), the primary causes of acid rain. To achieve this goal at the lowest cost to society, the program employs both regulatory and market based approaches for controlling air pollution.

Antioxidant

Antioxidants are compounds that inhibit oxidation (usually occurring as autoxidation), a chemical reaction that can produce free radicals. Autoxidation leads to degradation of organic compounds, including living matter. Antioxidants are frequently added to industrial products, such as polymers, fuels, and lubricants, to extend their usable lifetimes. Food are also treated with antioxidants to forestall spoilage, in particular the rancidification of oils and fats. In cells, antioxidants such as glutathione, mycothiol or bacillithiol, and enzyme systems like superoxide dismutase, can prevent damage from oxidative stress. Known dietary antioxidants are vitamins A, C, and E, but the term antioxidant has also been applied to numerous other dietary compounds that only have antioxidant properties in vitro, with little evidence for antioxidant properties in vivo. Dietary supplements marketed as antioxidants have not been shown to maintain health or prevent disease in humans. History As part of their adaptation from marine life, terrestrial plants began producing non-marine antioxidants such as ascorbic acid (vitamin C), polyphenols and tocopherols. The evolution of angiosperm plants between 50 and 200 million years ago resulted in the development of many antioxidant pigments – particularly during the Jurassic period – as chemical defences against reactive oxygen species that are byproducts of photosynthesis. Originally, the term antioxidant specifically referred to a chemical that prevented the consumption of oxygen. In the late 19th and early 20th centuries, extensive study concentrated on the use of antioxidants in important industrial processes, such as the prevention of metal corrosion, the vulcanization of rubber, and the polymerization of fuels in the fouling of internal combustion engines. Early research on the role of antioxidants in biology focused on their use in preventing the oxidation of unsaturated fats, which is the cause of rancidity. Antioxidant activity could be measured simply by placing the fat in a closed container with oxygen and measuring the rate of oxygen consumption. However, it was the identification of vitamins C and E as antioxidants that revolutionized the field and led to the realization of the importance of antioxidants in the biochemistry of living organisms. The possible mechanisms of action of antioxidants were first explored when it was recognized that a substance with anti-oxidative activity is likely to be one that is itself readily oxidized. Research into how vitamin E prevents the process of lipid peroxidation led to the identification of antioxidants as reducing agents that prevent oxidative reactions, often by scavenging reactive oxygen species before they can damage cells. Uses in technology Food preservatives Antioxidants are used as food additives to help guard against food deterioration. Exposure to oxygen and sunlight are the two main factors in the oxidation of food, so food is preserved by keeping in the dark and sealing it in containers or even coating it in wax, as with cucumbers. However, as oxygen is also important for plant respiration, storing plant materials in anaerobic conditions produces unpleasant flavors and unappealing colors. Consequently, packaging of fresh fruits and vegetables contains an ≈8% oxygen atmosphere. Antioxidants are an especially important class of preservatives as, unlike bacterial or fungal spoilage, oxidation reactions still occur relatively rapidly in frozen or refrigerated food. These preservatives include natural antioxidants such as ascorbic acid (AA, E300) and tocopherols (E306), as well as synthetic antioxidants such as propyl gallate (PG, E310), tertiary butylhydroquinone (TBHQ), butylated hydroxyanisole (BHA, E320) and butylated hydroxytoluene (BHT, E321). Unsaturated fats can be highly susceptible to oxidation, causing rancidification. Oxidized lipids are often discolored and can impart unpleasant tastes and flavors. Thus, these foods are rarely preserved by drying; instead, they are preserved by smoking, salting, or fermenting. Even less fatty foods such as fruits are sprayed with sulfurous antioxidants prior to air drying. Metals catalyse oxidation. Some fatty foods such as olive oil are partially protected from oxidation by their natural content of antioxidants. Fatty foods are sensitive to photooxidation, which forms hydroperoxides by oxidizing unsaturated fatty acids and ester. Exposure to ultraviolet (UV) radiation can cause direct photooxidation and decompose peroxides and carbonyl molecules. These molecules undergo free radical chain reactions, but antioxidants inhibit them by preventing the oxidation processes. Cosmetics preservatives Antioxidant stabilizers are also added to fat-based cosmetics such as lipstick and moisturizers to prevent rancidity. Antioxidants in cosmetic products prevent oxidation of active ingredients and lipid content. For example, phenolic antioxidants such as stilbenes, flavonoids, and hydroxycinnamic acid strongly absorb UV radiation due to the presence of chromophores. They reduce oxidative stress from sun exposure by absorbing UV light. Industrial uses Antioxidants may be added to industrial products, such as stabilizers in fuels and additives in lubricants, to prevent oxidation and polymerization that leads to the formation of engine-fouling residues. Antioxidant polymer stabilizers are widely used to prevent the degradation of polymers such as rubbers, plastics and adhesives that causes a loss of strength and flexibility in these materials. Polymers containing double bonds in their main chains, such as natural rubber and polybutadiene, are especially susceptible to oxidation and ozonolysis. They can be protected by antiozonants. Oxidation can be accelerated by UV radiation in natural sunlight to cause photo-oxidation. Various specialised light stabilisers, such as HALS may be added to plastics to prevent this. Synthetic phenolic and aminic antioxidants are increasingly being identified as potential human and environmental health hazards. Environmental and health hazards Synthetic phenolic antioxidants (SPAs) and aminic antioxidants have potential human and environmental health hazards. SPAs are common in indoor dust, small air particles, sediment, sewage, river water and wastewater. They are synthesized from phenolic compounds and include 2,6-di-tert-butyl-4-methylphenol (BHT), 2,6-di-tert-butyl-p-benzoquinone (BHT-Q), 2,4-di-tert-butyl-phenol (DBP) and 3-tert-butyl-4-hydroxyanisole (BHA). BHT can cause hepatotoxicity and damage to the endocrine system and may increase tumor development rates due to dimethylhydrazine. BHT-Q can cause DNA damage and mismatches through the cleavage process, generating superoxide radicals. DBP is toxic to marine life if exposed long-term. Phenolic antioxidants have low biodegradability, but they do not have severe toxicity toward aquatic organisms at low concentrations. Another type of antioxidant, diphenylamine (DPA), is commonly used in the production of commercial, industrial lubricants and rubber products and it also acts as a supplement for automotive engine oils. Oxidative challenge in biology The vast majority of complex life on Earth requires oxygen for its metabolism, but this same oxygen is a highly reactive element that can damage living organisms. Organisms contain chemicals and enzymes that minimize this oxidative damage without interfering with the beneficial effect of oxygen. In general, antioxidant systems either prevent these reactive species from being formed, or remove them, thus minimizing their damage. Reactive oxygen species can have useful cellular functions, such as redox signaling. Thus, ideally, antioxidant systems do not remove oxidants entirely, but maintain them at some optimum concentration. Reactive oxygen species produced in cells include hydrogen peroxide (H2O2), hypochlorous acid (HClO), and free radicals such as the hydroxyl radical (·OH) and the superoxide anion (O2−). The hydroxyl radical is particularly unstable and will react rapidly and non-specifically with most biological molecules. This species is produced from hydrogen peroxide in metal-catalyzed redox reactions such as the Fenton reaction. These oxidants can damage cells by starting chemical chain reactions such as lipid peroxidation, or by oxidizing DNA or proteins. Damage to DNA can cause mutations and possibly cancer, if not reversed by DNA repair mechanisms, while damage to proteins causes enzyme inhibition, denaturation and protein degradation. The use of oxygen as part of the process for generating metabolic energy produces reactive oxygen species. In this process, the superoxide anion is produced as a by-product of several steps in the electron transport chain. Particularly important is the reduction of coenzyme Q in complex III, since a highly reactive free radical is formed as an intermediate (Q·−). This unstable intermediate can lead to electron "leakage", when electrons jump directly to oxygen and form the superoxide anion, instead of moving through the normal series of well-controlled reactions of the electron transport chain. Peroxide is also produced from the oxidation of reduced flavoproteins, such as complex I. However, although these enzymes can produce oxidants, the relative importance of the electron transfer chain to other processes that generate peroxide is unclear. In plants, algae, and cyanobacteria, reactive oxygen species are also produced during photosynthesis, particularly under conditions of high light intensity. This effect is partly offset by the involvement of carotenoids in photoinhibition, and in algae and cyanobacteria, by large amount of iodide and selenium, which involves these antioxidants reacting with over-reduced forms of the photosynthetic reaction centres to prevent the production of reactive oxygen species. Examples of bioactive antioxidant compounds Physiological antioxidants are classified into two broad divisions, depending on whether they are soluble in water (hydrophilic) or in lipids (lipophilic). In general, water-soluble antioxidants react with oxidants in the cell cytosol and the blood plasma, while lipid-soluble antioxidants protect cell membranes from lipid peroxidation. These compounds may be synthesized in the body or obtained from the diet. The different antioxidants are present at a wide range of concentrations in body fluids and tissues, with some such as glutathione or ubiquinone mostly present within cells, while others such as uric acid are more systemically distributed (see table below). Some antioxidants are only found in a few organisms, and can be pathogens or virulence factors. The interactions between these different antioxidants may be synergistic and interdependent. The action of one antioxidant may therefore depend on the proper function of other members of the antioxidant system. The amount of protection provided by any one antioxidant will also depend on its concentration, its reactivity towards the particular reactive oxygen species being considered, and the status of the antioxidants with which it interacts. Some compounds contribute to antioxidant defense by chelating transition metals and preventing them from catalyzing the production of free radicals in the cell. The ability to sequester iron for iron-binding proteins, such as transferrin and ferritin, is one such function. Selenium and zinc are commonly referred to as antioxidant minerals, but these chemical elements have no antioxidant action themselves, but rather are required for the activity of antioxidant enzymes, such as glutathione reductase and superoxide dismutase. (See also selenium in biology and zinc in biology.) Uric acid Uric acid (UA) is an antioxidant oxypurine produced from xanthine by the enzyme xanthine oxidase, and is an intermediate product of purine metabolism. In almost all land animals, urate oxidase further catalyzes the oxidation of uric acid to allantoin, but in humans and most higher primates, the urate oxidase gene is nonfunctional, so that UA is not further broken down. The evolutionary reasons for this loss of urate conversion to allantoin remain the topic of active speculation. The antioxidant effects of uric acid have led researchers to suggest this mutation was beneficial to early primates and humans. Studies of high altitude acclimatization support the hypothesis that urate acts as an antioxidant by mitigating the oxidative stress caused by high-altitude hypoxia. Uric acid has the highest concentration of any blood antioxidant and provides over half of the total antioxidant capacity of human serum. Uric acid's antioxidant activities are also complex, given that it does not react with some oxidants, such as superoxide, but does act against peroxynitrite, peroxides, and hypochlorous acid. Concerns over elevated UA's contribution to gout must be considered one of many risk factors. By itself, UA-related risk of gout at high levels (415–530 μmol/L) is only 0.5% per year with an increase to 4.5% per year at UA supersaturation levels (535+ μmol/L). Many of these aforementioned studies determined UA's antioxidant actions within normal physiological levels, and some found antioxidant activity at levels as high as 285 μmol/L. Vitamin C Ascorbic acid or vitamin C is a monosaccharide oxidation-reduction (redox) catalyst found in both animals and plants. As one of the enzymes needed to make ascorbic acid has been lost by mutation during primate evolution, humans must obtain it from their diet; it is therefore a dietary vitamin. Most other animals are able to produce this compound in their bodies and do not require it in their diets. Ascorbic acid is required for the conversion of the procollagen to collagen by oxidizing proline residues to hydroxyproline. In other cells, it is maintained in its reduced form by reaction with glutathione, which can be catalysed by protein disulfide isomerase and glutaredoxins. Ascorbic acid is a redox catalyst which can reduce, and thereby neutralize, reactive oxygen species such as hydrogen peroxide. In addition to its direct antioxidant effects, ascorbic acid is also a substrate for the redox enzyme ascorbate peroxidase, a function that is used in stress resistance in plants. Ascorbic acid is present at high levels in all parts of plants and can reach concentrations of 20 millimolar in chloroplasts. Glutathione Glutathione is a cysteine-containing peptide found in most forms of aerobic life. It is not required in the diet and is instead synthesized in cells from its constituent amino acids. Glutathione has antioxidant properties since the thiol group in its cysteine moiety is a reducing agent and can be reversibly oxidized and reduced. In cells, glutathione is maintained in the reduced form by the enzyme glutathione reductase and in turn reduces other metabolites and enzyme systems, such as ascorbate in the glutathione-ascorbate cycle, glutathione peroxidases and glutaredoxins, as well as reacting directly with oxidants. Due to its high concentration and its central role in maintaining the cell's redox state, glutathione is one of the most important cellular antioxidants. In some organisms glutathione is replaced by other thiols, such as by mycothiol in the Actinomycetes, bacillithiol in some gram-positive bacteria, or by trypanothione in the Kinetoplastids. Vitamin E Vitamin E is the collective name for a set of eight related tocopherols and tocotrienols, which are fat-soluble vitamins with antioxidant properties. Of these, α-tocopherol has been most studied as it has the highest bioavailability, with the body preferentially absorbing and metabolising this form. It has been claimed that the α-tocopherol form is the most important lipid-soluble antioxidant, and that it protects membranes from oxidation by reacting with lipid radicals produced in the lipid peroxidation chain reaction. This removes the free radical intermediates and prevents the propagation reaction from continuing. This reaction produces oxidised α-tocopheroxyl radicals that can be recycled back to the active reduced form through reduction by other antioxidants, such as ascorbate, retinol or ubiquinol. This is in line with findings showing that α-tocopherol, but not water-soluble antioxidants, efficiently protects glutathione peroxidase 4 (GPX4)-deficient cells from cell death. GPx4 is the only known enzyme that efficiently reduces lipid-hydroperoxides within biological membranes. However, the roles and importance of the various forms of vitamin E are presently unclear, and it has even been suggested that the most important function of α-tocopherol is as a signaling molecule, with this molecule having no significant role in antioxidant metabolism. The functions of the other forms of vitamin E are even less well understood, although γ-tocopherol is a nucleophile that may react with electrophilic mutagens, and tocotrienols may be important in protecting neurons from damage. Pro-oxidant activities Antioxidants that are reducing agents can also act as pro-oxidants. For example, vitamin C has antioxidant activity when it reduces oxidizing substances such as hydrogen peroxide; however, it will also reduce metal ions such as iron and copper that generate free radicals through the Fenton reaction. While ascorbic acid is effective antioxidant, it can also oxidatively change the flavor and color of food. With the presence of transition metals, there are low concentrations of ascorbic acid that can act as a radical scavenger in the Fenton reaction. 2 Fe3+ + Ascorbate → 2 Fe2+ + Dehydroascorbate 2 Fe2+ + 2 H2O2 → 2 Fe3+ + 2 OH· + 2 OH− The relative importance of the antioxidant and pro-oxidant activities of antioxidants is an area of current research, but vitamin C, which exerts its effects as a vitamin by oxidizing polypeptides, appears to have a mostly antioxidant action in the human body. Enzyme systems As with the chemical antioxidants, cells are protected against oxidative stress by an interacting network of antioxidant enzymes. Here, the superoxide released by processes such as oxidative phosphorylation is first converted to hydrogen peroxide and then further reduced to give water. This detoxification pathway is the result of multiple enzymes, with superoxide dismutases catalysing the first step and then catalases and various peroxidases removing hydrogen peroxide. As with antioxidant metabolites, the contributions of these enzymes to antioxidant defenses can be hard to separate from one another, but the generation of transgenic mice lacking just one antioxidant enzyme can be informative. Superoxide dismutase, catalase, and peroxiredoxins Superoxide dismutases (SODs) are a class of closely related enzymes that catalyze the breakdown of the superoxide anion into oxygen and hydrogen peroxide. SOD enzymes are present in almost all aerobic cells and in extracellular fluids. Superoxide dismutase enzymes contain metal ion cofactors that, depending on the isozyme, can be copper, zinc, manganese or iron. In humans, the copper/zinc SOD is present in the cytosol, while manganese SOD is present in the mitochondrion. There also exists a third form of SOD in extracellular fluids, which contains copper and zinc in its active sites. The mitochondrial isozyme seems to be the most biologically important of these three, since mice lacking this enzyme die soon after birth. In contrast, the mice lacking copper/zinc SOD (Sod1) are viable but have numerous pathologies and a reduced lifespan (see article on superoxide), while mice without the extracellular SOD have minimal defects (sensitive to hyperoxia). In plants, SOD isozymes are present in the cytosol and mitochondria, with an iron SOD found in chloroplasts that is absent from vertebrates and yeast. Catalases are enzymes that catalyse the conversion of hydrogen peroxide to water and oxygen, using either an iron or manganese cofactor. This protein is localized to peroxisomes in most eukaryotic cells. Catalase is an unusual enzyme since, although hydrogen peroxide is its only substrate, it follows a ping-pong mechanism. Here, its cofactor is oxidised by one molecule of hydrogen peroxide and then regenerated by transferring the bound oxygen to a second molecule of substrate. Despite its apparent importance in hydrogen peroxide removal, humans with genetic deficiency of catalase — "acatalasemia" — or mice genetically engineered to lack catalase completely, experience few ill effects. Peroxiredoxins are peroxidases that catalyze the reduction of hydrogen peroxide, organic hydroperoxides, as well as peroxynitrite. They are divided into three classes: typical 2-cysteine peroxiredoxins; atypical 2-cysteine peroxiredoxins; and 1-cysteine peroxiredoxins. These enzymes share the same basic catalytic mechanism, in which a redox-active cysteine (the peroxidatic cysteine) in the active site is oxidized to a sulfenic acid by the peroxide substrate. Over-oxidation of this cysteine residue in peroxiredoxins inactivates these enzymes, but this can be reversed by the action of sulfiredoxin. Peroxiredoxins seem to be important in antioxidant metabolism, as mice lacking peroxiredoxin 1 or 2 have shortened lifespans and develop hemolytic anaemia, while plants use peroxiredoxins to remove hydrogen peroxide generated in chloroplasts. Thioredoxin and glutathione systems The thioredoxin system contains the 12-kDa protein thioredoxin and its companion thioredoxin reductase. Proteins related to thioredoxin are present in all sequenced organisms. Plants, such as Arabidopsis thaliana, have a particularly great diversity of isoforms. The active site of thioredoxin consists of two neighboring cysteines, as part of a highly conserved CXXC motif, that can cycle between an active dithiol form (reduced) and an oxidized disulfide form. In its active state, thioredoxin acts as an efficient reducing agent, scavenging reactive oxygen species and maintaining other proteins in their reduced state. After being oxidized, the active thioredoxin is regenerated by the action of thioredoxin reductase, using NADPH as an electron donor. The glutathione system includes glutathione, glutathione reductase, glutathione peroxidases, and glutathione S-transferases. This system is found in animals, plants and microorganisms. Glutathione peroxidase is an enzyme containing four selenium-cofactors that catalyzes the breakdown of hydrogen peroxide and organic hydroperoxides. There are at least four different glutathione peroxidase isozymes in animals. Glutathione peroxidase 1 is the most abundant and is a very efficient scavenger of hydrogen peroxide, while glutathione peroxidase 4 is most active with lipid hydroperoxides. Surprisingly, glutathione peroxidase 1 is dispensable, as mice lacking this enzyme have normal lifespans, but they are hypersensitive to induced oxidative stress. In addition, the glutathione S-transferases show high activity with lipid peroxides. These enzymes are at particularly high levels in the liver and also serve in detoxification metabolism. Health research Relation to diet The dietary antioxidant vitamins A, C, and E are essential and required in specific daily amounts to prevent diseases. Polyphenols, which have antioxidant properties in vitro due to their free hydroxy groups, are extensively metabolized by catechol-O-methyltransferase which methylates free hydroxyl groups, and thereby prevents them from acting as antioxidants in vivo. Interactions Common pharmaceuticals (and supplements) with antioxidant properties may interfere with the efficacy of certain anticancer medication and radiation therapy. Pharmaceuticals and supplements that have antioxidant properties suppress the formation of free radicals by inhibiting oxidation processes. Radiation therapy induce oxidative stress that damages essential components of cancer cells, such as proteins, nucleic acids, and lipids that comprise cell membranes. Adverse effects Relatively strong reducing acids can have antinutrient effects by binding to dietary minerals such as iron and zinc in the gastrointestinal tract and preventing them from being absorbed. Examples are oxalic acid, tannins and phytic acid, which are high in plant-based diets. Calcium and iron deficiencies are not uncommon in diets in developing countries where less meat is eaten and there is high consumption of phytic acid from beans and unleavened whole grain bread. However, germination, soaking, or microbial fermentation are all household strategies that reduce the phytate and polyphenol content of unrefined cereal. Increases in Fe, Zn and Ca absorption have been reported in adults fed dephytinized cereals compared with cereals containing their native phytate. High doses of some antioxidants may have harmful long-term effects. The Beta-Carotene and Retinol Efficacy Trial (CARET) study of lung cancer patients found that smokers given supplements containing beta-carotene and vitamin A had increased rates of lung cancer. Subsequent studies confirmed these adverse effects. These harmful effects may also be seen in non-smokers, as one meta-analysis including data from approximately 230,000 patients showed that β-carotene, vitamin A or vitamin E supplementation is associated with increased mortality, but saw no significant effect from vitamin C. No health risk was seen when all the randomized controlled studies were examined together, but an increase in mortality was detected when only high-quality and low-bias risk trials were examined separately. As the majority of these low-bias trials dealt with either elderly people, or people with disease, these results may not apply to the general population. This meta-analysis was later repeated and extended by the same authors, confirming the previous results. These two publications are consistent with some previous meta-analyses that also suggested that vitamin E supplementation increased mortality, and that antioxidant supplements increased the risk of colon cancer. Beta-carotene may also increase lung cancer. Overall, the large number of clinical trials carried out on antioxidant supplements suggest that either these products have no effect on health, or that they cause a small increase in mortality in elderly or vulnerable populations. Exercise and muscle soreness A 2017 review showed that taking antioxidant dietary supplements before or after exercise does not likely lead to a noticeable reduction in muscle soreness after a person exercises. Levels in food Antioxidant vitamins are found in vegetables, fruits, eggs, legumes and nuts. Vitamins A, C, and E can be destroyed by long-term storage or prolonged cooking. The effects of cooking and food processing are complex, as these processes can also increase the bioavailability of antioxidants, such as some carotenoids in vegetables. Processed food contains fewer antioxidant vitamins than fresh and uncooked foods, as preparation exposes food to heat and oxygen. Other antioxidants are not obtained from the diet, but instead are made in the body. For example, ubiquinol (coenzyme Q) is poorly absorbed from the gut and is made through the mevalonate pathway. Another example is glutathione, which is made from amino acids. As any glutathione in the gut is broken down to free cysteine, glycine and glutamic acid before being absorbed, even large oral intake has little effect on the concentration of glutathione in the body. Although large amounts of sulfur-containing amino acids such as acetylcysteine can increase glutathione, no evidence exists that eating high levels of these glutathione precursors is beneficial for healthy adults. Measurement and invalidation of ORAC Measurement of polyphenol and carotenoid content in food is not a straightforward process, as antioxidants collectively are a diverse group of compounds with different reactivities to various reactive oxygen species. In food science analyses in vitro, the oxygen radical absorbance capacity (ORAC) was once an industry standard for estimating antioxidant strength of whole foods, juices and food additives, mainly from the presence of polyphenols. Earlier measurements and ratings by the United States Department of Agriculture were withdrawn in 2012 as biologically irrelevant to human health, referring to an absence of physiological evidence for polyphenols having antioxidant properties in vivo. Consequently, the ORAC method, derived only from in vitro experiments, is no longer considered relevant to human diets or biology, as of 2010. Alternative in vitro measurements of antioxidant content in foods – also based on the presence of polyphenols – include the Folin-Ciocalteu reagent, and the Trolox equivalent antioxidant capacity assay.

Bonn

Bonn () is a federal city in the German state of North Rhine-Westphalia, located on the banks of the Rhine. It has a population of over 300,000. About south-southeast of Cologne, Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants. It is a university city, was the birthplace of Ludwig van Beethoven and was the capital of West Germany from 1949 to 1990. Bonn was the seat of government of reunited Germany from 1990 to 1999. Founded in the 1st century BC as a Roman settlement in the province Germania Inferior, Bonn is one of Germany's oldest cities. It was the capital city of the Electorate of Cologne from 1597 to 1794, residence of the Archbishops and Prince-electors of Cologne. From 1949 to 1990, Bonn was the capital of West Germany, and Germany's present constitution, the Basic Law, was declared in the city in 1949. The era when Bonn served as the capital of West Germany is referred to by historians as the Bonn Republic. Due to a political compromise (Berlin-Bonn Act) following the reunification, the German federal government maintains a substantial presence in Bonn. Roughly a third of all ministerial jobs are located in Bonn , and the city is considered a second, unofficial, capital of the country. Bonn is the secondary seat of the President, the Chancellor, and the Bundesrat, and the primary seat of six federal government ministries and twenty federal authorities. The title of Federal City () reflects its important political status within Germany. The headquarters of Deutsche Post DHL and Deutsche Telekom, both DAX-listed corporations, are in Bonn. The city is home to the University of Bonn and a total of 20 United Nations institutions, the highest number in all of Germany. These institutions include the headquarters for Secretariat of the UN Framework Convention Climate Change (UNFCCC), the Secretariat of the UN Convention to Combat Desertification (UNCCD), and the UN Volunteers programme. Geography Topography Situated in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area with over 11 million inhabitants, Bonn lies within the German state of North Rhine-Westphalia, on the border with Rhineland-Palatinate. Spanning an area of more on both sides of the river Rhine, almost three-quarters of the city lies on the river's left bank. To the south and to the west, Bonn borders the Eifel region which encompasses the Rhineland Nature Park. To the north, Bonn borders the Cologne Lowland. Natural borders are constituted by the river Sieg to the north-east and by the Siebengebirge (also known as the Seven Hills) to the east. The largest extension of the city in north–south dimensions is and in west–east dimensions. The city borders have a total length of . The geographical centre of Bonn is the Bundeskanzlerplatz (Chancellor Square) in Bonn-Gronau. Administration The German state of North Rhine-Westphalia is divided into five governmental districts (), and Bonn is part of the governmental district of Cologne (). Within this governmental district, the city of Bonn is an urban district in its own right. The urban district of Bonn is then again divided into four administrative municipal districts (). These are Bonn, Bonn-Bad Godesberg, Bonn-Beuel and Bonn-Hardtberg. In 1969, the independent towns of Bad Godesberg and Beuel as well as several villages were incorporated into Bonn, resulting in a city more than twice as large as before. Climate Bonn has an oceanic climate (Cfb). In the south of the Cologne lowland in the Rhine valley, Bonn is in one of Germany's warmest regions. History Founding and Roman period The history of the city dates back to Roman times. In about 12 BC, the Roman army appears to have stationed a small unit in what is presently the historical centre of the city. Even earlier, the army had resettled members of a Germanic tribal group allied with Rome, the Ubii, in Bonn. The Latin name for that settlement, "Bonna", may stem from the original population of this and many other settlements in the area, the Eburoni. The Eburoni were members of a large tribal coalition effectively wiped out during the final phase of Caesar's War in Gaul. After several decades, the army gave up the small camp linked to the Ubii-settlement. During the 1st century AD, the army then chose a site to the north of the emerging town in what is now the section of Bonn-Castell to build a large military installation dubbed Castra Bonnensis, i.e., literally, "Fort Bonn". Initially built from wood, the fort was eventually rebuilt in stone. With additions, changes and new construction, the fort remained in use by the army into the waning days of the Western Roman Empire, possibly the mid-5th century. The structures themselves remained standing well into the Middle Ages, when they were called the Bonnburg. They were used by Frankish kings until they fell into disuse. Eventually, much of the building materials seem to have been re-used in the construction of Bonn's 13th-century city wall. The (star gate) in the city center is a reconstruction using the last remnants of the medieval city wall. To date, Bonn's Roman fort remains the largest fort of its type known from the ancient world, i.e. a fort built to accommodate a full-strength Imperial Legion and its auxiliaries. The fort covered an area of approximately . Between its walls it contained a dense grid of streets and a multitude of buildings, ranging from spacious headquarters and large officers' quarters to barracks, stables and a military jail. Among the legions stationed in Bonn, the "1st", i.e. the Prima Legio Minervia, seems to have served here the longest. Units of the Bonn legion were deployed to theatres of war ranging from modern-day Algeria to what is now the Russian republic of Chechnya. The chief Roman road linking the provincial capitals of Cologne and Mainz cut right through the fort where it joined the fort's main road (now, Römerstraße). Once past the South Gate, the Cologne–Mainz road continued along what are now streets named Belderberg, Adenauerallee et al. On both sides of the road, the local settlement, Bonna, grew into a sizeable Roman town. Bonn is shown on the 4th century Peutinger Map. In late antiquity, much of the town seems to have been destroyed by marauding invaders. The remaining civilian population then took refuge inside the fort along with the remnants of the troops stationed here. During the final decades of Imperial rule, the troops were supplied by Franci chieftains employed by the Roman administration. When the end came, these troops simply shifted their allegiances to the new barbarian rulers, the Kingdom of the Franks. From the fort, the Bonnburg, as well as from a new medieval settlement to the South centered around what later became the minster, grew the medieval city of Bonn. Local legends arose from this period that the name of the village came from Saint Boniface via Vulgar Latin *Bonnifatia, but this proved to be a myth. Middle ages and early modern period Between the 11th and 13th centuries, the Romanesque style Bonn Minster was built, and in 1597 Bonn became the seat of the Archdiocese of Cologne. The city gained more influence and grew considerably. The city was subject to a major bombardment during the Siege of Bonn in 1689. Bonn was then returned to Cologne where it remained the capital at the Peace of Ryswick. The elector Clemens August (ruled 1723–1761) ordered the construction of a series of Baroque buildings which still give the city its character. Another memorable ruler was Max Franz (ruled 1784–1794), who founded the university and the spa quarter of Bad Godesberg. In addition he was a patron of the young Ludwig van Beethoven, who was born in Bonn in 1770; the elector financed the composer's first journey to Vienna. In 1794, the city was seized by French troops, becoming a part of the First French Empire. In 1815 following the Napoleonic Wars, Bonn became part of the Kingdom of Prussia. Administered within the Prussian Rhine Province, the city became part of the German Empire in 1871 during the Prussian-led unification of Germany. Bonn was of little relevance in these years. 20th century and the "Bonn Republic" During the Second World War, Bonn acquired military significance because of its strategic location on the Rhine, which formed a natural barrier to easy penetration into the German heartland from the west. The Allied ground advance into Germany reached Bonn on 7 March 1945, and the US 1st Infantry Division captured the city during the battle of 8–9 March 1945. After the Second World War, Bonn was in the British zone of occupation. Following the advocacy of West Germany's first chancellor, Konrad Adenauer, a former Cologne Mayor and a native of that area, Bonn became the de facto capital, officially designated the "temporary seat of the Federal institutions," of the newly formed Federal Republic of Germany in 1949. However, the Bundestag, seated in Bonn's Bundeshaus, affirmed Berlin's status as the German capital. Bonn was chosen as the provisional capital and seat of government despite the fact that Frankfurt already had most of the required facilities and using Bonn was estimated to be 95 million DM more expensive than using Frankfurt. Bonn was chosen because Adenauer and other prominent politicians intended to make Berlin the capital of the reunified Germany, and they felt that locating the capital in a major city like Frankfurt or Hamburg would imply a permanent capital and even weaken support in West Germany for reunification. In 1949, the Parliamentary Council in Bonn drafted and adopted the current German constitution, the Basic Law for the Federal Republic of Germany. As the political centre of West Germany, Bonn saw six Chancellors and six Presidents of the Federal Republic of Germany. Bonn's time as the capital of West Germany is commonly referred to as the Bonn Republic, in contrast to the Berlin Republic which followed reunification in 1990. After national reunification German reunification in 1990 made Berlin the nominal capital of Germany again. This decision, however, did not mandate that the republic's political institutions would also move. While some argued for the seat of government to move to Berlin, others advocated leaving it in Bonn – a situation roughly analogous to that of the Netherlands, where Amsterdam is the capital but The Hague is the seat of government. Berlin's previous history as united Germany's capital was strongly connected with the German Empire, the Weimar Republic and more ominously with both Nazi Germany and Prussia. It was felt that a new peacefully united Germany should not be governed from a city connected to such overtones of war. Additionally, Bonn was closer to Brussels, headquarters of the European Economic Community. Former West German chancellor and mayor of West Berlin Willy Brandt caused considerable offence to the Western Allies during the debate by stating that France would not have kept the seat of government at Vichy after Liberation. The heated debate that resulted was settled by the Bundestag (Germany's parliament) only on 20 June 1991. By a vote of 338–320, the Bundestag voted to move the seat of government to Berlin. The vote broke largely along regional lines, with legislators from the south and west favouring Bonn and legislators from the north and east voting for Berlin. It also broke along generational lines as well; older legislators with memories of Berlin's past glory favoured Berlin, while younger legislators favoured Bonn. Ultimately, the votes of the eastern German legislators tipped the balance in favour of Berlin. From 1990 to 1999, Bonn served as the seat of government of reunited Germany. In recognition of its former status as German capital, it holds the name of Federal City (). Bonn currently shares the status of Germany's seat of government with Berlin, with the President, the Chancellor and many government ministries (such as Food & Agriculture and Defence) maintaining large presences in Bonn. Over 8,000 of the 18,000 federal officials remain in Bonn. A total of 19 United Nations (UN) institutions operate from Bonn today. Politics and government Mayor The current Mayor of Bonn is Katja Dörner of Alliance 90/The Greens since 2020.

It used to be based in the Rococo-style (old city hall), built in 1737, located adjacent to Bonn's central market square. However, due to the enlargement of Bonn in 1969 through the incorporation of Beuel and Bad Godesberg, it moved into the larger Stadthaus facilities further north. This was necessary for the city council to accommodate an increased number of representatives. The mayor of Bonn still sits in the , which is also used for representative and official purposes.

The last election took place in May 2017. The current delegates are Guido Déus (CDU), Christos Katzidis (CDU), Joachim Stamp (FDP) and Franziska Müller-Rech (FDP). Federal government Bonn's constituency is called (096). In the German federal election 2017, Ulrich Kelber (SPD) was elected a member of German Federal parliament, the Bundestag by direct mandate. It is his fifth term. Katja Dörner representing Bündnis 90/Die Grünen and Alexander Graf Lambsdorff for FDP were elected as well. Kelber resigned in 2019 because he was appointed Federal Commissioner for Data Protection and Freedom of Information. As Dörner was elected Lord Mayor of Bonn in September 2020, she resigned as a member of parliament after her entry into office. Culture Beethoven's birthplace is located in Bonngasse near the market place. Next to the market place is the Old City Hall, built in 1737 in Rococo style, under the rule of Clemens August of Bavaria. It is used for receptions of guests of the city, and as an office for the mayor. Nearby is the Kurfürstliches Schloss, built as a residence for the prince-elector and now the main building of the University of Bonn. The Poppelsdorfer Allee is an avenue flanked by Chestnut trees which had the first horsecar of the city. It connects the Kurfürstliches Schloss with the Poppelsdorfer Schloss, a palace that was built as a resort for the prince-electors in the first half of the 18th century, and whose grounds are now a botanical garden (the Botanischer Garten Bonn). This axis is interrupted by a railway line and Bonn Hauptbahnhof, a building erected in 1883/84. The Beethoven Monument stands on the Münsterplatz, which is flanked by the Bonn Minster, one of Germany's oldest churches. The three highest structures in the city are the WDR radio mast in Bonn-Venusberg (), the headquarters of the Deutsche Post called Post Tower () and the former building for the German members of parliament Langer Eugen () now the location of the UN Campus. Churches Bonn Minster Doppelkirche Schwarzrheindorf built in 1151 Old Cemetery Bonn (Alter Friedhof), one of the best known cemeteries in Germany , built in 1627 with Johann Balthasar Neumann's Heilige Stiege, it is a stairway for Christian pilgrims St. Remigius, where Beethoven was baptized Castles and residences Godesburg fortress ruins The Röttgen suburb was once home to Schloss Herzogsfreude, now lost, but once a hunting lodge of elector Clemens August.

The Haus der Geschichte is one of the foremost German museums of contemporary German history, with branches in Berlin and Leipzig. In its permanent exhibition, the Haus der Geschichte presents German history from 1945 until the present, also shedding light on Bonn's own role as former capital of West Germany. Numerous temporary exhibitions emphasize different features, such as Nazism or important personalities in German history. The Kunstmuseum Bonn or Bonn Museum of Modern Art is an art museum founded in 1947. The Kunstmuseum exhibits both temporary exhibitions and its permanent collection. The latter is focused on Rhenish Expressionism and post-war German art. German artists on display include Georg Baselitz, Joseph Beuys, Hanne Darboven, Anselm Kiefer, Blinky Palermo and Wolf Vostell. The museum owns one of the largest collections of artwork by Expressionist painter August Macke. His work is also on display in the August-Macke-Haus, located in Macke's former home where he lived from 1911 to 1914. The Bundeskunsthalle (full name: Kunst- und Ausstellungshalle der Bundesrepublik Deutschland or Art and Exhibition Hall of the Federal Republic of Germany), focuses on the crossroads of culture, arts, and science. To date, it attracted more than 17 million visitors. One of its main objectives is to show the cultural heritage outside of Germany or Europe. Next to its changing exhibitions, the Bundeskunsthalle regularly hosts concerts, discussion panels, congresses, and lectures. The Museum Koenig is Bonn's natural history museum. Affiliated with the University of Bonn, it is also a zoological research institution housing the Leibniz-Institut für Biodiversität der Tiere. Politically interesting, it is on the premises of the Museum Koenig where the Parlamentarischer Rat first met. The Deutsches Museum Bonn, affiliated with one of the world's foremost science museums, the Deutsches Museum in Munich, is an interactive science museum focusing on post-war German scientists, engineers, and inventions. Other museums include the Beethoven House, birthplace of Ludwig van Beethoven, the Rheinisches Landesmuseum Bonn (Rhinish Regional Museum Bonn), the Bonn Women's Museum, the Rheinisches Malermuseum and the Arithmeum. Nature There are several parks, leisure and protected areas in and around Bonn. The is Bonn's most important leisure park, with its role being comparable to what Central Park is for New York City. It lies on the banks of the Rhine and is the city's biggest park intra muros. The Rhine promenade and the Alter Zoll (Old Toll Station) are in direct neighbourhood of the city centre and are popular amongst both residents and visitors. The Arboretum Park Härle is an arboretum with specimens dating to back to 1870. The Botanischer Garten (Botanical Garden) is affiliated with the university. The natural reserve of Kottenforst is a large area of protected woods on the hills west of the city centre. It is about in area and part of the Rhineland Nature Park (). In the very south of the city, on the border with Wachtberg and Rhineland-Palatinate, there is an extinct volcano, the Rodderberg, featuring a popular area for hikes. Also south of the city, there is the Siebengebirge which is part of the lower half of the Middle Rhine region. The nearby upper half of the Middle Rhine from Bingen to Koblenz is a UNESCO World Heritage Site with more than 40 castles and fortresses from the Middle Ages and important German vineyards. Transportation Air traffic Named after Konrad Adenauer, the first post-war Chancellor of West Germany, Cologne Bonn Airport is situated north-east from the city centre of Bonn. With around 10.3 million passengers passing through it in 2015, it is the seventh-largest passenger airport in Germany and the third-largest in terms of cargo operations. By traffic units, which combines cargo and passengers, the airport is in fifth position in Germany. As of March 2015, Cologne Bonn Airport had services to 115 passenger destinations in 35 countries. The airport is one of Germany's few 24-hour airports, and is a hub for Eurowings and cargo operators FedEx Express and UPS Airlines. The federal motorway (Autobahn) A59 connects the airport with the city. Long distance and regional trains to and from the airport stop at Cologne/Bonn Airport station. Another major airport within a one-hour drive by car is Düsseldorf International Airport. Rail and bus system Bonn's central railway station, Bonn Hauptbahnhof is the city's main public transportation hub. It lies just outside the old town and near the central university buildings. It is served by regional (S-Bahn and Regionalbahn) and long-distance (IC and ICE) trains. Daily, more than 67,000 people travel via Bonn Hauptbahnhof. In late 2016, around 80 long distance and more than 165 regional trains departed to or from Bonn every day. Another long-distance station, (Siegburg/Bonn), is located in the nearby town of Siegburg and serves as Bonn's station on the high-speed rail line between Cologne and Frankfurt, offering faster connections to Southern Germany. It can be reached by Stadtbahn line 66 (approx. 25 minutes from central Bonn). Bonn has a Stadtbahn light rail and a tram system. The Bonn Stadtbahn has 4 regular lines that connect the main north–south axis (centre to Bad Godesberg) and quarters east of the Rhine (Beuel and Oberkassel), as well as many nearby towns like Brühl, Wesseling, Sankt Augustin, Siegburg, Königswinter, and Bad Honnef. All lines serve the Central Station and two lines continue to Cologne, where they connect to the Cologne Stadtbahn. The Bonn tram system consists of two lines that connect closer quarters in the south, north and east of Bonn to the Central Station. While the Stadtbahn mostly has its own right-of-way, the tram often operates on general road lanes. A few sections of track are used by both systems. These urban rail lines are supplemented by a bus system of roughly 30 regular lines, especially since some parts of the city like Hardtberg and most of Bad Godesberg completely lack a Stadtbahn/Tram connection. Several lines offer night services, especially during the weekends. Bonn is part of the Verkehrsverbund Rhein-Sieg (Rhine-Sieg Transport Association) which is the public transport association covering the area of the Cologne/Bonn Region. Road network Four Autobahns run through or are adjacent to Bonn: the A59 (right bank of the Rhine, connecting Bonn with Düsseldorf and Duisburg), the A555 (left bank of the Rhine, connecting Bonn with Cologne), the A562 (connecting the right with the left bank of the Rhine south of Bonn), and the A565 (connecting the A59 and the A555 with the A61 to the southwest). Three Bundesstraßen, which have a general speed limit in contrast to the Autobahn, connect Bonn to its immediate surroundings (Bundesstraßen B9, B42 and B56). With Bonn being divided into two parts by the Rhine, three bridges are crucial for inner-city road traffic: the Konrad-Adenauer-Brücke (A562) in the South, the Friedrich-Ebert-Brücke (A565) in the North, and the Kennedybrücke (B56) in the centre. In addition, regular ferries operate between Bonn-Mehlem and Königswinter, Bonn-Bad Godesberg and Königswinter-Niederdollendorf, and Bonn-Graurheindorf and Niederkassel-Mondorf. Port Located in the northern sub-district of Graurheindorf, the inland harbour of Bonn is used for container traffic as well as oversea transport. The annual turnover amounts to around . Regular passenger transport occurs to Cologne and Düsseldorf. Economy The head offices of Deutsche Telekom, its subsidiary T-Mobile, Deutsche Post, German Academic Exchange Service, and SolarWorld are in Bonn. The third largest employer in the city of Bonn is the University of Bonn (including the university clinics) and Stadtwerke Bonn also follows as a major employer. On the other hand, there are several traditional, nationally known private companies in Bonn such as luxury food producers Verpoorten and Kessko, the Klais organ manufacture and the Bonn flag factory. The largest confectionery manufacturer in Europe, Haribo, has its founding headquarters (founded in 1922) and a production site in Bonn.

About 70% of the population was entirely of German origin, while about 100,000 people, equating to roughly 30%, were at least partly of non-German origin. The city is one of the fastest-growing municipalities in Germany and the 18th most populous city in the country. Bonn's population is predicted to surpass the populations of Wuppertal and Bochum before the year 2030. The following list shows the largest groups of origin of minorites with "migration background" in Bonn . Sports Bonn is home of the Telekom Baskets Bonn, the only basketball club in Germany that owns its arena, the Telekom Dome. The club is the reigning champion of the 2022–23 Basketball Champions League. The city also has a semi-professional football team Bonner SC which was formed in 1965 through the merger of Bonner FV and Tura Bonn. The Bonn Gamecocks American football team play at the 12,000-capacity Stadion Pennenfeld. The headquarters of the International Paralympic Committee has been located in Bonn since 1999. The successful German Baseball Team Bonn Capitals are also found in the city of Bonn. International relations Since 1983, the City of Bonn has established friendship relations with the City of Tel Aviv, Israel, and since 1988 Bonn, in former times the residence of the Princes Electors of Cologne, and Potsdam, Germany, the formerly most important residential city of the Prussian rulers, have established a city-to-city partnership. Central Bonn is surrounded by a number of traditional towns and villages which were independent up to several decades ago. As many of those communities had already established their own contacts and partnerships before the regional and local reorganisation in 1969, the Federal City of Bonn now has a dense network of city district partnerships with European partner towns. The city district of Bonn is a partner of the English university city of Oxford, England, UK (since 1947), of Budafok, District XXII of Budapest, Hungary (since 1991) and of Opole, Poland (officially since 1997; contacts were established 1954). The district of Bad Godesberg has established partnerships with Saint-Cloud in France, Frascati in Italy, Windsor and Maidenhead in England, UK and Kortrijk in Belgium; a friendship agreement has been signed with the town of Yalova, Turkey. The district of Beuel on the right bank of the Rhine and the city district of Hardtberg foster partnerships with towns in France: Mirecourt and Villemomble. Moreover, the city of Bonn has developed a concept of international co-operation and maintains sustainability oriented project partnerships in addition to traditional city twinning, among others with Minsk in Belarus, Ulaanbaatar in Mongolia, Bukhara in Uzbekistan, Chengdu in China and La Paz in Bolivia. Twin towns – sister cities Bonn is twinned with: Bukhara, Uzbekistan (1999) Cape Coast, Ghana (2012) Chengdu, China (2009) Kherson, Ukraine (2023) Minsk, Belarus (1993) La Paz, Bolivia (1996) Potsdam, Germany (1988) Tel Aviv, Israel (1983) Ulaanbaatar, Mongolia (1993) Bonn city district is twinned with: Oxford, United Kingdom (1947) Budafok-Tétény (Budapest), Hungary (1991) For twin towns of other city districts, see Bad Godesberg, Beuel and Hardtberg.

Ballroom dance

Ballroom dance is a set of partner dances, which are enjoyed both socially and competitively around the world, mostly because of its performance and entertainment aspects. Ballroom dancing is also widely enjoyed on stage, film, and television. Ballroom dance may refer, at its widest definition, to almost any recreational dance with a partner. However, with the emergence of dance competition (now known as Dancesport), two principal schools have emerged and the term is used more narrowly to refer to the dances recognized by those schools. The International School, originally developed in England and now regulated by the World Dance Council (WDC) and the World DanceSport Federation (WDSF), is most prevalent in Europe. It encompasses two categories, Standard and Latin, each of which consist of five dances—International Waltz, International Tango, International Viennese Waltz, International Slow Foxtrot, and International Quickstep in the Standard category and International Samba, International Cha Cha, International Rumba, International Paso Doble, and International Jive in the Latin category. A "Standard" or "Latin" competition encompasses all five dances in the respective category, and a "Ten Dance" competition encompasses all ten dances. The two styles, while differing in technique, rhythm, and costumes, exemplify core elements of ballroom dancing such as control and cohesiveness. The American School, also called North American School, is most prevalent in the United States and Canada, where it's regulated by USA Dance and Canada Dancesport (CDS) -- the respective national member bodies of the WDSF. It also consists of two categories analogous to the Standard and Latin categories of the International School, respectively called Smooth and Rhythm. The Smooth category consists of only four dances—American Waltz, American Tango, American Foxtrot, and American Viennese Waltz, omitting American Peabody (the American School equivalent to Quickstep) -- while the dances selected for competition in the Rhythm category are American Cha Cha, American Rumba, American East Coast Swing (the American School equivalent to International Jive), American Bolero, and American Mambo. A "Smooth" or "Rhythm" competition encompasses the dances in the respective category, and a "Nine Dance" competition encompassing all nine of these dances is analogous to the "Ten Dance" competition of the International School. USA Dance additionally recognizes American Peabody, American Merengue, American Paso Doble, American Samba, American West Coast Swing, American Polka, and American Hustle as ballroom dances in which sanctioned competition may take place. Note that dances of the two schools that bear the same name may differ considerably in permitted patterns (figures), technique, and styling. Exhibitions and social situations that feature ballroom dancing also may include additional partner dances such as Lindy Hop, Night Club Two Step, Night Club Swing, Bachata, Country Two Step, and regional (local or national) favorites that normally are not regarded as part of the ballroom family, and a number of historical dances also may be danced in ballrooms or salons. Additionally, some sources regard Sequence Dancing, in pairs or other formations, to be a style of ballroom dance. Definitions and history The term 'ballroom dancing' is derived from the word ball which in turn originates from the Latin word ballare which means 'to dance' (a ball-room being a large room specially designed for such dances). In times past, ballroom dancing was social dancing for the privileged, leaving folk dancing for the lower classes. These boundaries have since become blurred. The definition of ballroom dance also depends on the era: balls have featured popular dances of the day such as the Minuet, Quadrille, Polonaise, Polka, Mazurka, and others, which are now considered to be historical dances. Early modern period The first authoritative knowledge of the earliest ballroom dances was recorded toward the end of the 16th century, when Jehan Tabourot, under the pen name "Thoinot-Arbeau", published in 1588 his Orchésographie, a study of late 16th-century French renaissance social dance. Among the dances described were the solemn basse danse, the livelier branle, pavane, and the galliarde which Shakespeare called the "cinq pace" as it was made of five steps. In 1650, the Minuet, originally a peasant dance of Poitou, was introduced into Paris and set to music by Jean-Baptiste Lully and danced by the King Louis XIV in public. The Minuet dominated the ballroom from that time until the close of the 18th century. Toward the later half of the 17th century, Louis XIV founded his 'Académie Royale de Musique et de Danse', where specific rules for the execution of every dance and the "five positions" of the feet were formulated for the first time by members of the Académie. Eventually, the first definite cleavage between ballet and ballroom came when professional dancers appeared in the ballets, and the ballets left the Court and went to the stage. Ballet technique such as the turned out positions of the feet, however, lingered for over two centuries and past the end of the Victoria era. 19th century The waltz with its modern hold took root in England in about 1812; in 1819 Carl Maria von Weber wrote Invitation to the Dance, which marked the adoption of the waltz form into the sphere of absolute music. The dance was initially met with tremendous opposition due to the semblance of impropriety associated with the closed hold, though the stance gradually softened. In the 1840s several new dances made their appearance in the ballroom, including the polka, mazurka, and the Schottische. In the meantime a strong tendency emerged to drop all 'decorative' steps such as entrechats and ronds de jambes that had found a place in the Quadrilles and other dances. Early 20th century Modern ballroom dance has its roots early in the 20th century, when several different things happened more or less at the same time. The first was a movement away from the sequence dances towards dances where the couples moved independently. This had been pre-figured by the waltz, which had already made this transition. The second was a wave of popular music, such as jazz. Since dance is to a large extent tied to music, this led to a burst of newly invented dances. There were many dance crazes in the period 1910–1930. The third event was a concerted effort to transform some of the dance crazes into dances which could be taught to a wider dance public in the U.S. and Europe. Here Vernon and Irene Castle were important, and so was a generation of English dancers in the 1920s, including Josephine Bradley and Victor Silvester. These professionals analysed, codified, published, and taught a number of standard dances. It was essential, if popular dance was to flourish, for dancers to have some basic movements they could confidently perform with any partner they might meet. Here the huge Arthur Murray organisation in America, and the dance societies in England, such as the Imperial Society of Teachers of Dancing, were highly influential. Finally, much of this happened during and after a period of World War, and the effect of such a conflict in dissolving older social customs was considerable. Later, in the 1930s, the on-screen dance pairing of Fred Astaire and Ginger Rogers influenced all forms of dance in the U.S. and elsewhere. Although both actors had separate careers, their filmed dance sequences together, which included portrayals of the Castles, have reached iconic status. Much of Astaire and Rogers' work portrayed social dancing, although the performances were highly choreographed (often by Astaire or Hermes Pan) and meticulously staged and rehearsed. Competitive dancing Competitions, sometimes referred to as dancesport, range from world championships, regulated by the World Dance Council (WDC), to less advanced dancers at various proficiency levels. Most competitions are divided into professional and amateur, though in the USA pro-am competitions typically accompany professional competitions. The International Olympic Committee now recognizes competitive ballroom dance. It has recognized another body, the World DanceSport Federation (WDSF), as the sole representative body for dancesport in the Olympic Games. Ballroom dance competitions are regulated by each country in its own way. There are about 30 countries which compete regularly in international competitions. There are another 20 or so countries which have membership of the WDC and/or the WDSF, but whose dancers rarely appear in international competitions. In Britain there is the British Dance Council, which grants national and regional championship titles, such as the British Ballroom Championships, the British Sequence Championships and the United Kingdom Championships. In the United States, the member branches of the WDC (National Dance Council of America) and the WDSF (USA Dance) both grant national and regional championship titles. Ballroom dancing competitions in the former USSR also included the Soviet Ballroom dances, or Soviet Programme. Australian New Vogue is danced both competitively and socially. In competition, there are 15 recognized New Vogue dances, which are performed by the competitors in sequence. These dance forms are not recognized internationally, neither are the US variations such as American Smooth, and Rhythm. Such variations in dance and competition methods are attempts to meets perceived needs in the local market-place. Internationally, the Blackpool Dance Festival, hosted annually at Blackpool, England is considered the most prestigious event a dancesport competitor can attend. Formation dance is another style of competitive dance recognized by the WDSF. In this style, multiple dancers (usually in couples and typically up to 16 dancers at one time) compete on the same team, moving in and out of various formations while dancing. The Blackpool Dance Festival also holds an annual event for competitive formation dancing. Elements of competition In competitive ballroom, dancers are judged by diverse criteria such as poise, the hold or frame, posture, musicality and expression, timing, body alignment and shape, floor craft, foot and leg action, and presentation. Judging in a performance-oriented sport is inevitably subjective in nature, and controversy and complaints by competitors over judging placements are not uncommon. The scorekeepers—called scrutineers—will tally the total number recalls accumulated by each couple through each round until the finals when the Skating system is used to place each couple by ordinals, typically 1–6, though the number of couples in the final may vary. Sometimes, up to 8 couples may be present on the floor during the finals. Competitors dance at different levels based on their ability and experience. The levels are split into two categories, syllabus and open. The syllabus levels are newcomer/pre-bronze, bronze, silver, and gold—with gold the highest syllabus level and newcomer the lowest. In these levels, moves are restricted to those written in a syllabus, and illegal moves can lead to disqualification. Each level, bronze, silver, and gold, has different moves on their syllabus, increasing in difficulty. There are three levels in the open category; novice, pre-champ, and champ in increasing order of skill. At those levels, dancers no longer have restrictions on their moves, so complex routines are more common. Medal evaluations Medal evaluations for amateurs enable dancers' individual abilities to be recognized according to conventional standards. In medal evaluations, which are run by bodies such as the Imperial Society of Teachers of Dancing (ISTD) and the United Kingdom Alliance (UKA), each dancer performs two or more dances in a certain genre in front of a judge. Genres such as Modern Ballroom or Latin are the most popular. Societies such as the ISTD and UKA also offer medal tests on other dance styles (such as Country & Western, Rock 'n Roll or Tap). In some North American examinations, levels include Newcomer, Bronze, Silver, Gold, Novice, Pre-championship, and Championship; each level may be further subdivided into either two or four separate sections. Collegiate ballroom There is a part of the ballroom world dedicated to students. These chapters are typically clubs or teams that have an interest in ballroom dancing. Teams hold fundraisers, social events, and ballroom dance lessons. Ballroom dance teams' goals are to have fun and learn to dance well. There is a strong focus on finding a compatible dance partner and bonding with teammates. There is also a competitive side to collegiate ballroom - collegiate teams often hold competitions and invite other teams to participate. These competitions are often run with many of the same rules are regular amateur competitions as outlined above, but are usually organized entirely by collegiate teams. Examples include the MIT Open Ballroom Dance Competition, Big Apple Dancesport Challenge, Purdue Ballroom Classic, Cardinal Classic, Berkeley Classic, and Harvard Invitational. Dances "Ballroom dance" refers most often to the ten dances of Standard and Latin, though the term is also often used interchangeably with the five International Ballroom dances. Sequence dancing, which is danced predominantly in the United Kingdom, and its development New Vogue in Australia and New Zealand, are also sometimes included as a type of Ballroom dancing. In the United States and Canada, the American Style (American Smooth and American Rhythm) also exists. The dance technique used for both International and American styles is similar, but International Ballroom allows only closed dance positions, whereas American Smooth allows closed, open and separated dance movements. In addition, different sets of dance figures are usually taught for the two styles. International Latin and American Rhythm have different styling, and have different dance figures in their respective syllabi. Other dances sometimes placed under the umbrella "ballroom dance" include nightclub dances such as Lindy Hop, West Coast swing, nightclub two step, hustle, salsa, and merengue. The categorization of dances as "ballroom dances" has always been fluid, with new dances or folk dances being added to or removed from the ballroom repertoire from time to time, so no list of subcategories or dances is any more than a description of current practices. There are other dances historically accepted as ballroom dances, and are revived via the vintage dance movement. In Europe, Latin Swing dances include Argentine tango, mambo, Lindy Hop, swing boogie (sometimes also known as nostalgic boogie), and discofox. One example of this is the subcategory of cajun dances that originated in Acadiana, with branches reaching both coasts of the United States. Standard/Smooth dances are normally danced to Western music (often from the mid-twentieth century), and couples dance counter-clockwise around a rectangular floor following the line of dance. In competitions, competitors are costumed as would be appropriate for a white tie affair, with full gowns for the ladies and bow tie and tail coats for the men; though in American Smooth it is now conventional for the men to abandon the tailsuit in favor of shorter tuxedos, vests, and other creative outfits. Latin/Rhythm dances are commonly danced to contemporary Latin American music and (in case of jive) Western music. With the exception of a few traveling dances like samba and pasodoble, couples do not follow the line of dance but perform their routines more or less in one spot. In competitions, the women are often dressed in short-skirted Latin outfits while the men are outfitted in tight-fitting shirts and pants, the goal being to emphasize the dancers' leg action and body movements. Competitive dances Standard/Smooth Waltz Waltz began as a country folk dance in Austria and Bavaria in the 17th century. In the early 19th century it was introduced in England. It was the first dance where a man held a woman close to his body. When performing the dance, the upper body is kept to the left throughout all figures, the follower's body leans to the right side of the leader while the head is extended left to follow the elbow. Figures with rotation have little rise. The start of the rise begins slowly from the first count, peaks on the 2nd count and lowers slowly on the 3rd. Sway is also used on the second step to make the step longer and also to slow down the momentum by bringing the feet together. Waltz is performed for both International Standard and American Smooth. Viennese Waltz Viennese waltz originated in Provence area in France in 1559 and is recognized as the oldest of all ballroom dances. It was introduced in England as German waltz in 1812 and became popular throughout the 19th century by the music of Josef and Johann Strauss. It is often referred to as the classic “old-school” ballroom. Viennese Waltz music is quite fast. Slight shaping of the body moves towards the inside of the turn and shaping forward and up to lengthen the opposite side from direction. Reverse turn is used to travel down long side and is overturned. While natural turn is used to travel short side and is underturned to go around the corners. Viennese waltz is performed for both International Standard and American Smooth. Tango Tango originated in Buenos Aires in the late 19th century. Modern Argentine tango is danced in both open and closed embraces which focuses on the lead and follow moving in harmony of the tango's passionate charging music. The tango's technique is like walking to the music while keeping feet grounded and allowing ankles and knees to brush against one another during each step taken. Tango is a flat-footed dance and unlike the other dances, has no rise and fall. Body weight is kept over the toes and the connection is held between the dancers in the hips. Ballroom tango, however, is a dance with a far more open frame, often utilising strong and staccato movements. Ballroom tango, rather than Argentine tango, is performed in international competition. Foxtrot The foxtrot is an American dance, believed to be of African-American origin. It was named by a vaudeville performer Harry Fox in 1914. Fox was rapidly trotting step to ragtime music. The dance therefore was originally named as the “Fox’s trot”. The foxtrot can be danced at slow, medium, or fast tempos depending on the speed of the jazz or big band music. The partners are facing one another and frame rotates from one side to another, changing direction after a measure. The dance is generally danced flat, with not much rise and fall. The walking steps are taken as slow for the two beats per steps and quick for one beat per step. Foxtrot is performed for both International Standard and American Smooth. Quickstep The quickstep is an English dance and was invented in the 1920s as a combination of faster tempo of foxtrot and the Charleston. It is a fast moving dance, so men are allowed to close their feet and the couples move in short syncopated steps. Quickstep includes the walks, runs, chasses, and turns of the original foxtrot dance, with some other fast figures such as locks, hops, run, quick step, jump and skips. Quick step is performed as an International Standard dance. Latin/Rhythm Pasodoble The pasodoble originated from Spain and its dramatic bullfights. The dance is mostly performed only in competitions and rarely socially because of its many choreographic rules. The lead plays the role of the matador while the follow takes the role of the matador's cape, the bull, or even the matador. The chasse cape refers to the lead using the follow to turn them as if they are the cape, and the appel is when the lead stomps their foot to get the bull's attention. Pasodoble is performed as an International Latin dance. Spanish bolero The Spanish bolero was developed in the late 18th century out of the seguidilla, and its popularization is attributed to court dancers such as Sebastián Cerezo. It became one of the most popular ballroom dances of the 19th century and saw many classical adaptations. However, by the 20th century it had become old-fashioned. A Cuban music genre of the same name, bolero, which became popular in the early 20th century, is unrelated to the Spanish dance. Cuban bolero Although Cuban bolero was born as a form of trova, traditional singer/songwriter tradition from eastern Cuba, with no associated dance, it soon became a ballroom favorite in Cuba and all of Latin America. The dance most commonly represents the couple falling in love. Modern bolero is seen as a combination of many dances: like a slow salsa with contra-body movement of tango, patterns of rhumba, and rise and fall technique and personality of waltz and foxtrot. Bolero can be danced in a closed hold or singly and then coming back together. It is performed as an American Rhythm dance. Samba Samba is the national dance of Brazil. The rhythm of samba and its name originated from the language and culture of West African slaves. In 1905, samba became known to other countries during an exhibition in Paris. In the 1940s, samba was introduced in America through Carmen Miranda. The international version of Ballroom Samba has been based on an early version of Brazilian Samba called Maxixe, but has since developed away and differs strongly from Brazilian Ballroom Samba, which is called Samba de Gafieira. International Ballroom Samba is danced with a slight bounce which is created through the bending and straightening the knee. It is performed as an International Latin dance, although most of its modern development has occurred outside Latin America. Rumba Rumba came to the United States from Cuba in the 1920s and became a popular cabaret dance during prohibition. Rumba is a ballroom adaptation of son cubano and bolero (the Cuban genre) and, despite its name, it rarely included elements of Cuban rumba. It includes Cuban motions through knee-strengthening, figure-eight hip rotation, and swiveling foot action. An important characteristic of rumba is the powerful and direct lead achieved through the ball of the foot. Rumba is performed for both International Latin and American Rhythm. Mambo Mambo was developed as an offshoot of danzón, the national dance of Cuba, in the late 1930s by Orestes López and his brother Cachao, of Arcaño y sus Maravillas. They conceived a new form of danzón influenced by son cubano, with a faster, improvised final section, which allowed dancers to more freely express themselves, given that danzón had traditionally a very rigid structure. In the 1940s, Dámaso Pérez Prado transformed the mambo from the charanga into the big band format, and took it to Mexico and the United States, where it became a "dance craze". Cha Cha Cha Cha (sometimes wrongly called Cha Cha Cha based on a "street version" of the dance with shifted timing) was developed by Enrique Jorrín in the early 1950s, as a slower alternative to Mambo—and, in fact, was originally called Triple Mambo. The Cha Cha is a flirtatious dance with many hip rotations and partners synchronising their movements. The dance includes bending and straightening of the knee giving it a touch of Cuban motion. Cha-cha is performed for both International Latin and American Rhythm. East Coast Swing Swing in 1927 was originally named the Lindy Hop named by Shorty George Snowden. There have been 40 different versions documented over the years; most common is the East Coast swing which is performed in the American Smooth (or American Rhythm) only in the U.S. or Canada. The East Coast swing was established by Arthur Murray and others only shortly after World War II. Swing music is very lively and upbeat and can be danced to jazz or big band music. The swing dancing style has much bounce and energy. Swing also includes many spins and underarm turns. East Coast swing is performed as an American Rhythm dance. Jive The jive is part of the swing dance group and is a very lively variation of the jitterbug. Jive originated from African American clubs in the early 1940s. During World War II, American soldiers introduced the jive in England where it was adapted to today's competitive jive. In jive, the man leads the dance while the woman encourages the man to ask her to dance. It is danced to big band music, and some technique is taken from salsa, swing and tango. Jive is performed as an International Latin dance. Dance style classification International Style competition dances According to World Dance Council.

Baltic Sea

The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden, and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. It is a shelf sea and marginal sea of the Atlantic with limited water exchange between the two, making it an inland sea. The Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia (divided into the Bothnian Bay and the Bothnian Sea), the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The "Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German Bight of the North Sea via the Kiel Canal. Definitions Administration The Helsinki Convention on the Protection of the Marine Environment of the Baltic Sea Area includes the Baltic Sea and the Kattegat, without calling Kattegat a part of the Baltic Sea, "For the purposes of this Convention the 'Baltic Sea Area' shall be the Baltic Sea and the Entrance to the Baltic Sea, bounded by the parallel of the Skaw in the Skagerrak at 57°44.43'N." Traffic history Historically, the Kingdom of Denmark collected Sound Dues from ships at the border between the ocean and the land-locked Baltic Sea, in tandem: in the Øresund at Kronborg castle near Helsingør; in the Great Belt at Nyborg; and in the Little Belt at its narrowest part then Fredericia, after that stronghold was built. The narrowest part of Little Belt is the "Middelfart Sund" near Middelfart. Oceanography Geographers widely agree that the preferred physical border between the Baltic and North Seas is the Langelandsbælt (the southern part of the Great Belt strait near Langeland) and the Drogden-Sill strait. The Drogden Sill is situated north of Køge Bugt and connects Dragør in the south of Copenhagen to Malmö; it is used by the Øresund Bridge, including the Drogden Tunnel. By this definition, the Danish Straits is part of the entrance, but the Bay of Mecklenburg and the Bay of Kiel are parts of the Baltic Sea. Another usual border is the line between Falsterbo, Sweden, and Stevns Klint, Denmark, as this is the southern border of Øresund. It is also the border between the shallow southern Øresund (with a typical depth of 5–10 meters only) and notably deeper water. Hydrography and biology Drogden Sill (depth of ) sets a limit to Øresund and Darss Sill (depth of ), and a limit to the Belt Sea. The shallow sills are obstacles to the flow of heavy salt water from the Kattegat into the basins around Bornholm and Gotland. The Kattegat and the southwestern Baltic Sea are well oxygenated and have a rich biology. The remainder of the Sea is brackish, poor in oxygen, and in species. Thus, statistically, the more of the entrance that is included in its definition, the healthier the Baltic appears; conversely, the more narrowly it is defined, the more endangered its biology appears. Etymology and nomenclature Tacitus called it the Suebic Sea, Latin: Mare Suebicum after the Germanic people of the Suebi, and Ptolemy Sarmatian Ocean after the Sarmatians, but the first to name it the Baltic Sea () was the eleventh-century German chronicler Adam of Bremen. The origin of the latter name is speculative and it was adopted into Slavic and Finnic languages spoken around the sea, very likely due to the role of Medieval Latin in cartography. It might be connected to the Germanic word belt, a name used for two of the Danish straits, the Belts, while others claim it to be directly derived from the source of the Germanic word, Latin balteus "belt". Adam of Bremen himself compared the sea with a belt, stating that it is so named because it stretches through the land as a belt (Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam). He might also have been influenced by the name of a legendary island mentioned in the Natural History of Pliny the Elder. Pliny mentions an island named Baltia (or Balcia) with reference to accounts of Pytheas and Xenophon. It is possible that Pliny refers to an island named Basilia ("the royal") in On the Ocean by Pytheas. Baltia also might be derived from "belt", and therein mean "near belt of sea, strait". Others have suggested that the name of the island originates from the Proto-Indo-European root *bʰel meaning "white, fair", which may echo the naming of seas after colours relating to the cardinal points (as per Black Sea and Red Sea). This '*bʰel' root and basic meaning were retained in Lithuanian (as baltas), Latvian (as balts) and Slavic (as bely). On this basis, a related hypothesis holds that the name originated from this Indo-European root via a Baltic language such as Lithuanian. Another explanation is that, while derived from the aforementioned root, the name of the sea is related to names for various forms of water and related substances in several European languages, that might have been originally associated with colors found in swamps (compare Proto-Slavic *bolto "swamp"). Yet another explanation is that the name originally meant "enclosed sea, bay" as opposed to open sea. In the Middle Ages the sea was known by a variety of names. The name Baltic Sea became dominant only after 1600. Usage of Baltic and similar terms to denote the region east of the sea started only in the 19th century. Name in other languages The Baltic Sea was known in ancient Latin language sources as Mare Suebicum or even Mare Germanicum. Older native names in languages that used to be spoken on the shores of the sea or near it usually indicate the geographical location of the sea (in Germanic languages), or its size in relation to smaller gulfs (in Old Latvian), or tribes associated with it (in Old Russian the sea was known as the Varanghian Sea). In modern languages, it is known by the equivalents of "East Sea", "West Sea", or "Baltic Sea" in different languages: "Baltic Sea" is used in Modern English; in the Baltic languages Latvian (Baltijas jūra; in Old Latvian it was referred to as "the Big Sea", while the present day Gulf of Riga was referred to as "the Little Sea") and Lithuanian (Baltijos jūra); in Latin (Mare Balticum) and the Romance languages French (Mer Baltique), Italian (Mar Baltico), Portuguese (Mar Báltico), Romanian (Marea Baltică) and Spanish (Mar Báltico); in Greek ( Valtikí Thálassa); in Albanian (Deti Balltik); in Welsh (Môr Baltig); in the Slavic languages Polish (Morze Bałtyckie or Bałtyk), Czech (Baltské moře or Balt), Slovenian (Baltsko morje), Bulgarian ( Baltijsko More), Kashubian (Bôłt), Macedonian (Балтичко Море Baltičko More), Ukrainian ( Baltijs′ke More), Belarusian (Балтыйскае мора Baltyjskaje Mora), Russian ( Baltiyskoye More) and Serbo-Croatian (Baltičko more / ); in Hungarian (Balti-tenger). In Germanic languages, except English, "East Sea" is used, as in Afrikaans (Oossee), Danish (Østersøen ), Dutch (Oostzee), German (Ostsee), Low German (Oostsee), Icelandic and Faroese (Eystrasalt), Norwegian (Bokmål: Østersjøen ; Nynorsk: Austersjøen), and Swedish (Östersjön). In Old English it was known as Ostsǣ; also in Hungarian the former name was Keleti-tenger ("East-sea", due to German influence). In addition, Finnish, a Finnic language, uses the term Itämeri "East Sea", possibly a calque from a Germanic language. As the Baltic is not particularly eastward in relation to Finland, the use of this term may be a leftover from the period of Swedish rule. In another Finnic language, Estonian, it is called the "West Sea" (Läänemeri), with the correct geography (the sea is west of Estonia). In South Estonian, it has the meaning of both "West Sea" and "Evening Sea" (Õdagumeri). In the endangered Livonian language of Latvia, the sea (and sometimes the Irbe Strait as well) is called the "Large Sea" (Sūŗ meŗ or Sūr meŗ). History Classical world At the time of the Roman Empire, the Baltic Sea was known as the Mare Suebicum or Mare Sarmaticum. Tacitus in his AD 98 Agricola and Germania described the Mare Suebicum, named for the Suebi tribe, during the spring months, as a brackish sea where the ice broke apart and chunks floated about. The Suebi eventually migrated southwest to temporarily reside in the Rhineland area of modern Germany, where their name survives in the historic region known as Swabia. Jordanes called it the Germanic Sea in his work, the Getica. Middle Ages In the early Middle Ages, Norse (Scandinavian) merchants built a trade empire all around the Baltic. Later, the Norse fought for control of the Baltic against Wendish tribes dwelling on the southern shore. The Norse also used the rivers of Russia for trade routes, finding their way eventually to the Black Sea and southern Russia. This Norse-dominated period is referred to as the Viking Age. Since the Viking Age, the Scandinavians have referred to the Baltic Sea as Austmarr ("Eastern Lake"). "Eastern Sea", appears in the Heimskringla and Eystra salt appears in Sörla þáttr. Saxo Grammaticus recorded in Gesta Danorum an older name, Gandvik, -vik being Old Norse for "bay", which implies that the Vikings correctly regarded it as an inlet of the sea. Another form of the name, "Grandvik", attested in at least one English translation of Gesta Danorum, is likely to be a misspelling. In addition to fish the sea also provides amber, especially from its southern shores within today's borders of Poland, Russia and Lithuania. First mentions of amber deposits on the South Coast of the Baltic Sea date back to the 12th century. The bordering countries have also traditionally exported lumber, wood tar, flax, hemp and furs by ship across the Baltic. Sweden had from early medieval times exported iron and silver mined there, while Poland had and still has extensive salt mines. Thus, the Baltic Sea has long been crossed by much merchant shipping. The lands on the Baltic's eastern shore were among the last in Europe to be converted to Christianity. This finally happened during the Northern Crusades: Finland in the twelfth century by Swedes, and what are now Estonia and Latvia in the early thirteenth century by Danes and Germans (Livonian Brothers of the Sword). The Teutonic Order gained control over parts of the southern and eastern shore of the Baltic Sea, where they set up their monastic state. Lithuania was the last European state to convert to Christianity. An arena of conflict In the period between the 8th and 14th centuries, there was much piracy in the Baltic from the coasts of Pomerania and Prussia, and the Victual Brothers held Gotland. Starting in the 11th century, the southern and eastern shores of the Baltic were settled by migrants mainly from Germany, a movement called the Ostsiedlung ("east settling"). Other settlers were from the Netherlands, Denmark, and Scotland. The Polabian Slavs were gradually assimilated by the Germans. Denmark gradually gained control over most of the Baltic coast, until she lost much of her possessions after being defeated in the 1227 Battle of Bornhöved. In the 13th to 16th centuries, the strongest economic force in Northern Europe was the Hanseatic League, a federation of merchant cities around the Baltic Sea and the North Sea. In the sixteenth and early seventeenth centuries, Poland, Denmark, and Sweden fought wars for Dominium maris baltici ("Lordship over the Baltic Sea"). Eventually, it was Sweden that virtually encompassed the Baltic Sea. In Sweden, the sea was then referred to as Mare Nostrum Balticum ("Our Baltic Sea"). The goal of Swedish warfare during the 17th century was to make the Baltic Sea an all-Swedish sea (Ett Svenskt innanhav), something that was accomplished except the part between Riga in Latvia and Stettin in Pomerania. However, the Dutch dominated the Baltic trade in the seventeenth century. In the eighteenth century, Russia and Prussia became the leading powers over the sea. Sweden's defeat in the Great Northern War brought Russia to the eastern coast. Russia became and remained a dominating power in the Baltic. Russia's Peter the Great saw the strategic importance of the Baltic and decided to found his new capital, Saint Petersburg, at the mouth of the Neva river at the east end of the Gulf of Finland. There was much trading not just within the Baltic region but also with the North Sea region, especially eastern England and the Netherlands: their fleets needed the Baltic timber, tar, flax, and hemp. During the Crimean War, a joint British and French fleet attacked the Russian fortresses in the Baltic; the case is also known as the Åland War. They bombarded Sveaborg, which guards Helsinki; and Kronstadt, which guards Saint Petersburg; and they destroyed Bomarsund in Åland. After the unification of Germany in 1871, the whole southern coast became German. World War I was partly fought in the Baltic Sea. After 1920 Poland was granted access to the Baltic Sea at the expense of Germany by the Polish Corridor and enlarged the port of Gdynia in rivalry with the port of the Free City of Danzig. After the Nazis' rise to power, Germany reclaimed the Memelland and after the outbreak of the Eastern Front (World War II) occupied the Baltic states. In 1945, the Baltic Sea became a mass grave for retreating soldiers and refugees on torpedoed troop transports. The sinking of the Wilhelm Gustloff remains the worst maritime disaster in history, killing (very roughly) 9,000 people. In 2005, a Russian group of scientists found over five thousand airplane wrecks, sunken warships, and other material, mainly from World War II, on the bottom of the sea. Since World War II Since the end of World War II, various nations, including the Soviet Union, the United Kingdom and the United States have disposed of chemical weapons in the Baltic Sea, raising concerns of environmental contamination. Today, fishermen occasionally find some of these materials: the most recent available report from the Helsinki Commission notes that four small scale catches of chemical munitions representing approximately of material were reported in 2005. This is a reduction from the 25 incidents representing of material in 2003. Until now, the U.S. Government refuses to disclose the exact coordinates of the wreck sites. Deteriorating bottles leak mustard gas and other substances, thus slowly poisoning a substantial part of the Baltic Sea. After 1945, the German population was expelled from all areas east of the Oder-Neisse line, making room for new Polish and Russian settlement. Poland gained most of the southern shore. The Soviet Union gained another access to the Baltic with the Kaliningrad Oblast, that had been part of German-settled East Prussia. The Baltic states on the eastern shore were annexed by the Soviet Union. The Baltic then separated opposing military blocs: NATO and the Warsaw Pact. Neutral Sweden developed incident weapons to defend its territorial waters after the Swedish submarine incidents. This border status restricted trade and travel. It ended only after the collapse of the Communist regimes in Central and Eastern Europe in the late 1980s. In 2023, Finland joined NATO. Since May 2004, with the accession of the Baltic states and Poland, the Baltic Sea has been almost entirely surrounded by countries of the European Union (EU). The remaining non-EU shore areas are Russian: the Saint Petersburg area and the Kaliningrad Oblast exclave. Winter storms begin arriving in the region during October. These have caused numerous shipwrecks, and contributed to the extreme difficulties of rescuing passengers of the ferry M/S Estonia en route from Tallinn, Estonia, to Stockholm, Sweden, in September 1994, which claimed the lives of 852 people. Older, wood-based shipwrecks such as the Vasa tend to remain well-preserved, as the Baltic's cold and brackish water does not suit the shipworm. Storm floods Storm surge floods are generally taken to occur when the water level is more than one metre above normal. In Warnemünde about 110 floods occurred from 1950 to 2000, an average of just over two per year. Historic flood events were the All Saints' Flood of 1304 and other floods in the years 1320, 1449, 1625, 1694, 1784 and 1825. Little is known of their extent. From 1872, there exist regular and reliable records of water levels in the Baltic Sea. The highest was the flood of 1872 when the water was an average of above sea level at Warnemünde and a maximum of above sea level in Warnemünde. In the last very heavy floods the average water levels reached above sea level in 1904, in 1913, in January 1954, on 2–4 November 1995 and on 21 February 2002. Geography Geophysical data An arm of the North Atlantic Ocean, the Baltic Sea is enclosed by Sweden and Denmark to the west, Finland to the northeast, and the Baltic countries to the southeast. It is about long, an average of wide, and an average of deep. The maximum depth is which is on the Swedish side of the center. The surface area is about and the volume is about . The periphery amounts to about of coastline. The Baltic Sea is one of the largest brackish inland seas by area, and occupies a basin (a Zungenbecken) formed by glacial erosion during the last few ice ages. {| class="wikitable" |+Physical characteristics of the Baltic Sea, its main sub-regions, and the transition zone to the Skagerrak/North Sea area! style="background: DarkCyan; color: white; text-align: center"| Sub-area ! style="background: DarkCyan; color: white; text-align: center"| Area ! style="background: DarkCyan; color: white; text-align: center"| Volume ! style="background: DarkCyan; color: white; text-align: center"| Maximum depth ! style="background: DarkCyan; color: white; text-align: center"| Average depth |- ! style="background: DarkCyan; color: white; text-align: center"| ! style="background: DarkCyan; color: white; text-align: center"| km2 ! style="background: DarkCyan; color: white; text-align: center"| km3 ! style="background: DarkCyan; color: white; text-align: center"| m ! style="background: DarkCyan; color: white; text-align: center"| m |- | style="text-align: left"|Baltic proper | style="text-align: right"| 211,069 | style="text-align: right"| 13,045 | style="text-align: right"| 459 | style="text-align: right"| 62.1 |- | style="text-align: left"|Gulf of Bothnia | style="text-align: right"| 115,516 | style="text-align: right"| 6,389 | style="text-align: right"| 230 | style="text-align: right"| 60.2 |- | style="text-align: left"|Gulf of Finland | style="text-align: right"| 29,600 | style="text-align: right"| 1,100 | style="text-align: right"| 123 | style="text-align: right"| 38.0 |- | style="text-align: left"|Gulf of Riga | style="text-align: right"| 16,300 | style="text-align: right"| 424 | style="text-align: right"| > 60 | style="text-align: right"| 26.0 |- | style="text-align: left"| Belt Sea/Kattegat | style="text-align: right"| 42,408 | style="text-align: right"| 802 | style="text-align: right"| 109 | style="text-align: right"| 18.9 |- ! style="text-align: left"| Total Baltic Sea ! style="text-align: right"| 415,266 ! style="text-align: right"| 21,721 ! style="text-align: right"| 459 ! style="text-align: right"| 52.3 |} Extent The International Hydrographic Organization defines the limits of the Baltic Sea as follows: Bordered by the coasts of Germany, Denmark, Poland, Sweden, Finland, Russia, Estonia, Latvia, and Lithuania, it extends north-eastward of the following limits: In the Little Belt. A line joining Falshöft () and Vejsnæs Nakke (Ærø: ). In the Great Belt. A line joining Gulstav (South extreme of Langeland Island) and Kappel Kirke () on Island of Lolland. In the Guldborg Sound. A line joining Flinthorne-Rev and Skjelby (). In the Sound. A line joining Stevns Lighthouse () and Falsterbo Point (). Subdivisions The northern part of the Baltic Sea is known as the Gulf of Bothnia, of which the northernmost part is the Bay of Bothnia or Bothnian Bay. The more rounded southern basin of the gulf is called Bothnian Sea and immediately to the south of it lies the Sea of Åland. The Gulf of Finland connects the Baltic Sea with Saint Petersburg. The Gulf of Riga lies between the Latvian capital city of Riga and the Estonian island of Saaremaa. The Northern Baltic Sea lies between the Stockholm area, southwestern Finland, and Estonia. The Western and Eastern Gotland basins form the major parts of the Central Baltic Sea or Baltic proper. The Bornholm Basin is the area east of Bornholm, and the shallower Arkona Basin extends from Bornholm to the Danish isles of Falster and Zealand. In the south, the Bay of Gdańsk lies east of the Hel Peninsula on the Polish coast and west of the Sambia Peninsula in Kaliningrad Oblast. The Bay of Pomerania lies north of the islands of Usedom/Uznam and Wolin, east of Rügen. Between Falster and the German coast lie the Bay of Mecklenburg and Bay of Lübeck. The westernmost part of the Baltic Sea is the Bay of Kiel. The three Danish straits, the Great Belt, the Little Belt and The Sound (Öresund/Øresund), connect the Baltic Sea with the Kattegat and Skagerrak strait in the North Sea. Temperature and ice The water temperature of the Baltic Sea varies significantly depending on exact location, season and depth. At the Bornholm Basin, which is located directly east of the island of the same name, the surface temperature typically falls to during the peak of the winter and rises to during the peak of the summer, with an annual average of around . A similar pattern can be seen in the Gotland Basin, which is located between the island of Gotland and Latvia. In the deep of these basins the temperature variations are smaller. At the bottom of the Bornholm Basin, deeper than , the temperature typically is , and at the bottom of the Gotland Basin, at depths greater than , the temperature typically is . Generally, offshore locations, lower latitudes and islands maintain maritime climates, but adjacent to the water continental climates are common, especially on the Gulf of Finland. In the northern tributaries the climates transition from moderate continental to subarctic on the northernmost coastlines. On the long-term average, the Baltic Sea is ice-covered at the annual maximum for about 45% of its surface area. The ice-covered area during such a typical winter includes the Gulf of Bothnia, the Gulf of Finland, the Gulf of Riga, the archipelago west of Estonia, the Stockholm archipelago, and the Archipelago Sea southwest of Finland. The remainder of the Baltic does not freeze during a normal winter, except sheltered bays and shallow lagoons such as the Curonian Lagoon. The ice reaches its maximum extent in February or March; typical ice thickness in the northernmost areas in the Bothnian Bay, the northern basin of the Gulf of Bothnia, is about for landfast sea ice. The thickness decreases farther south. Freezing begins in the northern extremities of the Gulf of Bothnia typically in the middle of November, reaching the open waters of the Bothnian Bay in early January. The Bothnian Sea, the basin south of Kvarken, freezes on average in late February. The Gulf of Finland and the Gulf of Riga freeze typically in late January. In 2011, the Gulf of Finland was completely frozen on 15 February. The ice extent depends on whether the winter is mild, moderate, or severe. In severe winters ice can form around southern Sweden and even in the Danish straits. According to the 18th-century natural historian William Derham, during the severe winters of 1703 and 1708, the ice cover reached as far as the Danish straits. Frequently, parts of the Gulf of Bothnia and the Gulf of Finland are frozen, in addition to coastal fringes in more southerly locations such as the Gulf of Riga. This description meant that the whole of the Baltic Sea was covered with ice. Since 1720, the Baltic Sea has frozen over entirely 20 times, most recently in early 1987, which was the most severe winter in Scandinavia since 1720. The ice then covered . During the winter of 2010–11, which was quite severe compared to those of the last decades, the maximum ice cover was , which was reached on 25 February 2011. The ice then extended from the north down to the northern tip of Gotland, with small ice-free areas on either side, and the east coast of the Baltic Sea was covered by an ice sheet about wide all the way to Gdańsk. This was brought about by a stagnant high-pressure area that lingered over central and northern Scandinavia from around 10 to 24 February. After this, strong southern winds pushed the ice further into the north, and much of the waters north of Gotland were again free of ice, which had then packed against the shores of southern Finland. The effects of the afore-mentioned high-pressure area did not reach the southern parts of the Baltic Sea, and thus the entire sea did not freeze over. However, floating ice was additionally observed near Świnoujście harbor in January 2010. In recent years before 2011, the Bothnian Bay and the Bothnian Sea were frozen with solid ice near the Baltic coast and dense floating ice far from it. In 2008, almost no ice formed except for a short period in March. During winter, fast ice, which is attached to the shoreline, develops first, rendering ports unusable without the services of icebreakers. Level ice, ice sludge, pancake ice, and rafter ice form in the more open regions. The gleaming expanse of ice is similar to the Arctic, with wind-driven pack ice and ridges up to . Offshore of the landfast ice, the ice remains very dynamic all year, and it is relatively easily moved around by winds and therefore forms pack ice, made up of large piles and ridges pushed against the landfast ice and shores. In spring, the Gulf of Finland and the Gulf of Bothnia normally thaw in late April, with some ice ridges persisting until May in the eastern extremities of the Gulf of Finland. In the northernmost reaches of the Bothnian Bay, ice usually stays until late May; by early June it is practically always gone. However, in the famine year of 1867 remnants of ice were observed as late as 17 July near Uddskär. Even as far south as Øresund, remnants of ice have been observed in May on several occasions; near Taarbaek on 15 May 1942 and near Copenhagen on 11 May 1771. Drift ice was also observed on 11 May 1799. The ice cover is the main habitat for two large mammals, the grey seal (Halichoerus grypus) and the Baltic ringed seal (Pusa hispida botnica), both of which feed underneath the ice and breed on its surface. Of these two seals, only the Baltic ringed seal suffers when there is not adequate ice in the Baltic Sea, as it feeds its young only while on ice. The grey seal is adapted to reproducing also with no ice in the sea. The sea ice also harbors several species of algae that live in the bottom and inside unfrozen brine pockets in the ice. Due to the often fluctuating winter temperatures between above and below freezing, the saltwater ice of the Baltic Sea can be treacherous and hazardous to walk on, in particular in comparison to the more stable fresh water-ice sheets in the interior lakes. Hydrography The Baltic Sea flows out through the Danish straits; however, the flow is complex. A surface layer of brackish water discharges per year into the North Sea. Due to the difference in salinity, by salinity permeation principle, a sub-surface layer of more saline water moving in the opposite direction brings in per year. It mixes very slowly with the upper waters, resulting in a salinity gradient from top to bottom, with most of the saltwater remaining below deep. The general circulation is anti-clockwise: northwards along its eastern boundary, and south along with the western one . The difference between the outflow and the inflow comes entirely from fresh water. More than 250 streams drain a basin of about , contributing a volume of per year to the Baltic. They include the major rivers of north Europe, such as the Oder, the Vistula, the Neman, the Daugava and the Neva. Additional fresh water comes from the difference of precipitation less evaporation, which is positive. An important source of salty water is infrequent inflows (also known as major Baltic inflows or MBIs) of North Sea water into the Baltic. Such inflows, important to the Baltic ecosystem because of the oxygen they transport into the Baltic deeps, happen on average once per year, but large pulses that can replace the anoxic deep water in the Gotland Deep occur about once in ten years. Previously, it was believed that the frequency of MBIs had declined since 1980, but recent studies have challenged this view and no longer display a clear change in the frequency or intensity of saline inflows. Instead, a decadal variability in the intensities of MBIs is observed with a main period of approximately 30 years. The water level is generally far more dependent on the regional wind situation than on tidal effects. However, tidal currents occur in narrow passages in the western parts of the Baltic Sea. Tides can reach in the Gulf of Finland. The significant wave height is generally much lower than that of the North Sea. Quite violent, sudden storms sweep the surface ten or more times a year, due to large transient temperature differences and a long reach of the wind. Seasonal winds also cause small changes in sea level, of the order of . According to the media, during a storm in January 2017, an extreme wave above has been measured and significant wave height of around has been measured by the FMI. A numerical study has shown the presence of events with significant wave heights. Those extreme waves events can play an important role in the coastal zone on erosion and sea dynamics. Salinity The Baltic Sea is the world's largest inland brackish sea. Only two other brackish waters are larger according to some measurements: The Black Sea is larger in both surface area and water volume, but most of it is located outside the continental shelf (only a small fraction is inland). The Caspian Sea is larger in water volume, but—despite its name—it is a lake rather than a sea. The Baltic Sea's salinity is much lower than that of ocean water (which averages 3.5%), as a result of abundant freshwater runoff from the surrounding land (rivers, streams and alike), combined with the shallowness of the sea itself; runoff contributes roughly one-fortieth its total volume per year, as the volume of the basin is about and yearly runoff is about . The open surface waters of the Baltic Sea "proper" generally have a salinity of 0.3 to 0.9%, which is border-line freshwater. The flow of freshwater into the sea from approximately two hundred rivers and the introduction of salt from the southwest builds up a gradient of salinity in the Baltic Sea. The highest surface salinities, generally 0.7–0.9%, are in the southwesternmost part of the Baltic, in the Arkona and Bornholm basins (the former located roughly between southeast Zealand and Bornholm, and the latter directly east of Bornholm). It gradually falls further east and north, reaching the lowest in the Bothnian Bay at around 0.3%. Drinking the surface water of the Baltic as a means of survival would actually hydrate the body instead of dehydrating, as is the case with ocean water. As saltwater is denser than freshwater, the bottom of the Baltic Sea is saltier than the surface. This creates a vertical stratification of the water column, a halocline, that represents a barrier to the exchange of oxygen and nutrients, and fosters completely separate maritime environments. The difference between the bottom and surface salinities varies depending on location. Overall it follows the same southwest to east and north pattern as the surface. At the bottom of the Arkona Basin (equalling depths greater than ) and Bornholm Basin (depths greater than ) it is typically 1.4–1.8%. Further east and north the salinity at the bottom is consistently lower, being the lowest in Bothnian Bay (depths greater than ) where it is slightly below 0.4%, or only marginally higher than the surface in the same region. In contrast, the salinity of the Danish straits, which connect the Baltic Sea and Kattegat, tends to be significantly higher, but with major variations from year to year. For example, the surface and bottom salinity in the Great Belt is typically around 2.0% and 2.8% respectively, which is only somewhat below that of the Kattegat. The water surplus caused by the continuous inflow of rivers and streams to the Baltic Sea means that there generally is a flow of brackish water out through the Danish Straits to the Kattegat (and eventually the Atlantic). Significant flows in the opposite direction, salt water from the Kattegat through the Danish Straits to the Baltic Sea, are less regular and are known as major Baltic inflows (MBIs). Major tributaries The rating of mean discharges differs from the ranking of hydrological lengths (from the most distant source to the sea) and the rating of the nominal lengths. Göta älv, a tributary of the Kattegat, is not listed, as due to the northward upper low-salinity-flow in the sea, its water hardly reaches the Baltic proper: Islands and archipelagoes Åland (Finland, autonomous) Archipelago Sea (Finland) Pargas Nagu Korpo Houtskär Kustavi Kimito Blekinge archipelago (Sweden) Bornholm, including Christiansø (Denmark) Falster (Denmark) Gotland (Sweden) Hailuoto (Finland) Kotlin (Russia) Lolland (Denmark) Kvarken archipelago, including Valsörarna (Finland) Møn (Denmark) Öland (Sweden) Rügen (Germany) Stockholm archipelago (Sweden) Värmdön (Sweden) Usedom or Uznam (split between Germany and Poland) West Estonian archipelago (Estonia): Hiiumaa Muhu Saaremaa Vormsi Wolin (Poland) Zealand (Denmark) Coastal countries Countries that border the sea: Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden. Countries lands in the outer drainage basin: Belarus, Czech Republic, Norway, Slovakia, Ukraine. The Baltic Sea drainage basin is roughly four times the surface area of the sea itself. About 48% of the region is forested, with Sweden and Finland containing the majority of the forest, especially around the Gulfs of Bothnia and Finland. About 20% of the land is used for agriculture and pasture, mainly in Poland and around the edge of the Baltic Proper, in Germany, Denmark, and Sweden. About 17% of the basin is unused open land with another 8% of wetlands. Most of the latter are in the Gulfs of Bothnia and Finland. The rest of the land is heavily populated. About 85 million people live in the Baltic drainage basin, 15 million within of the coast and 29 million within of the coast. Around 22 million live in population centers of over 250,000. 90% of these are concentrated in the band around the coast. Of the nations containing all or part of the basin, Poland includes 45% of the 85 million, Russia 12%, Sweden 10% and the others less than 6% each.

Geological surveys show that before the Pleistocene, instead of the Baltic Sea, there was a wide plain around a great river that paleontologists call the Eridanos. Several Pleistocene glacial episodes scooped out the river bed into the sea basin. By the time of the last, or Eemian Stage (MIS 5e), the Eemian Sea was in place. Instead of a true sea, the Baltic can even today also be understood as the common estuary of all rivers flowing into it. From that time the waters underwent a geologic history summarized under the names listed below. Many of the stages are named after marine animals (e.g. the Littorina mollusk) that are clear markers of changing water temperatures and salinity. The factors that determined the sea's characteristics were the submergence or emergence of the region due to the weight of ice and subsequent isostatic readjustment, and the connecting channels it found to the North Sea-Atlantic, either through the straits of Denmark or at what are now the large lakes of Sweden, and the White Sea-Arctic Sea. Eemian Sea, 130,000–115,000 (years ago) Baltic Ice Lake, 12,600–10,300 Yoldia Sea, 10,300–9500 Ancylus Lake, 9,500–8,000 Mastogloia Sea, 8,000–7,500 Littorina Sea, 7,500–4,000 Post-Littorina Sea, 4,000–present The land is still emerging isostatically from its depressed state, which was caused by the weight of ice during the last glaciation. The phenomenon is known as post-glacial rebound. Consequently, the surface area and the depth of the sea are diminishing. The uplift is about eight millimeters per year on the Finnish coast of the northernmost Gulf of Bothnia. In the area, the former seabed is only gently sloping, leading to large areas of land being reclaimed in what are, geologically speaking, relatively short periods (decades and centuries). The "Baltic Sea anomaly" The "Baltic Sea anomaly" is a feature on an indistinct sonar image taken by Swedish salvage divers on the floor of the northern Baltic Sea in June 2011. The treasure hunters suggested the image showed an object with unusual features of seemingly extraordinary origin. Speculation published in tabloid newspapers claimed that the object was a sunken UFO. A consensus of experts and scientists say that the image most likely shows a natural geological formation. Biology Fauna and flora The fauna of the Baltic Sea is a mixture of marine and freshwater species. Among marine fishes are Atlantic cod, Atlantic herring, European hake, European plaice, European flounder, shorthorn sculpin and turbot, and examples of freshwater species include European perch, northern pike, whitefish and common roach. Freshwater species may occur at outflows of rivers or streams in all coastal sections of the Baltic Sea. Otherwise, marine species dominate in most sections of the Baltic, at least as far north as Gävle, where less than one-tenth are freshwater species. Further north the pattern is inverted. In the Bothnian Bay, roughly two-thirds of the species are freshwater. In the far north of this bay, saltwater species are almost entirely absent. For example, the common starfish and shore crab, two species that are very widespread along European coasts, are both unable to cope with the significantly lower salinity. Their range limit is west of Bornholm, meaning that they are absent from the vast majority of the Baltic Sea. Some marine species, like the Atlantic cod and European flounder, can survive at relatively low salinities but need higher salinities to breed, which therefore occurs in deeper parts of the Baltic Sea. The common blue mussel is the dominating animal species, and makes up more than 90% of the total animal biomass in the sea. There is a decrease in species richness from the Danish belts to the Gulf of Bothnia. The decreasing salinity along this path causes restrictions in both physiology and habitats. At more than 600 species of invertebrates, fish, aquatic mammals, aquatic birds and macrophytes, the Arkona Basin (roughly between southeast Zealand and Bornholm) is far richer than other more eastern and northern basins in the Baltic Sea, which all have less than 400 species from these groups, with the exception of the Gulf of Finland with more than 750 species. However, even the most diverse sections of the Baltic Sea have far fewer species than the almost-full saltwater Kattegat, which is home to more than 1600 species from these groups. The lack of tides has affected the marine species as compared with the Atlantic. Since the Baltic Sea is so young there are only two or three known endemic species: the brown alga Fucus radicans and the flounder Platichthys solemdali. Both appear to have evolved in the Baltic basin and were only recognized as species in 2005 and 2018 respectively, having formerly been confused with more widespread relatives. The tiny Copenhagen cockle (Parvicardium hauniense), a rare mussel, is sometimes considered endemic, but has now been recorded in the Mediterranean. However, some consider non-Baltic records to be misidentifications of juvenile lagoon cockles (Cerastoderma glaucum). Several widespread marine species have distinctive subpopulations in the Baltic Sea adapted to the low salinity, such as the Baltic Sea forms of the Atlantic herring and lumpsucker, which are smaller than the widespread forms in the North Atlantic. A peculiar feature of the fauna is that it contains a number of glacial relict species, isolated populations of arctic species which have remained in the Baltic Sea since the last glaciation, such as the large isopod Saduria entomon, the Baltic subspecies of ringed seal, and the fourhorn sculpin. Some of these relicts are derived from glacial lakes, such as Monoporeia affinis, which is a main element in the benthic fauna of the low-salinity Bothnian Bay. Cetaceans in the Baltic Sea are monitored by the countries bordering the sea and data compiled by various intergovernmental bodies, such as ASCOBANS. A critically endangered population of harbor porpoise inhabit the Baltic proper, whereas the species is abundant in the outer Baltic (Western Baltic and Danish Straits) and occasionally oceanic and out-of-range species such as minke whales, bottlenose dolphins, beluga whales, orcas, and beaked whales visit the waters. In recent years, very small, but with increasing rates, fin whalesJansson N.. 2007. "Vi såg valen i viken" . Aftonbladet. Retrieved on 7 September 2017 and humpback whales migrate into Baltic sea including mother and calf pair. Now extinct Atlantic grey whales (remains found from Gräsö along Bothnian Sea/southern Bothnian Gulf and Ystad) and eastern population of North Atlantic right whales that is facing functional extinction once migrated into Baltic Sea. Other notable megafauna include the basking sharks. Environmental status Satellite images taken in July 2010 revealed a massive algal bloom covering in the Baltic Sea. The area of the bloom extended from Germany and Poland to Finland. Researchers of the phenomenon have indicated that algal blooms have occurred every summer for decades. Fertilizer runoff from surrounding agricultural land has exacerbated the problem and led to increased eutrophication. Approximately of the Baltic's seafloor (a quarter of its total area) is a variable dead zone. The more saline (and therefore denser) water remains on the bottom, isolating it from surface waters and the atmosphere. This leads to decreased oxygen concentrations within the zone. It is mainly bacteria that grow in it, digesting organic material and releasing hydrogen sulfide. Because of this large anaerobic zone, the seafloor ecology differs from that of the neighboring Atlantic. Plans to artificially oxygenate areas of the Baltic that have experienced eutrophication have been proposed by the University of Gothenburg and Inocean AB. The proposal intends to use wind-driven pumps to inject oxygen (air) into waters at, or around, 130m below sea level. After World War II, Germany had to be disarmed and large quantities of ammunition stockpiles were disposed directly into the Baltic Sea and the North Sea. Environmental experts and marine biologists warn that these ammunition dumps pose a major environmental threat with potentially life-threatening consequences to the health and safety of humans on the coastlines of these seas. Economy Construction of the Great Belt Bridge in Denmark (completed 1997) and the Øresund Bridge-Tunnel (completed 1999), linking Denmark with Sweden, provided a highway and railroad connection between Sweden and the Danish mainland (the Jutland Peninsula, precisely the Zealand). The undersea tunnel of the Øresund Bridge-Tunnel provides for navigation of large ships into and out of the Baltic Sea. The Baltic Sea is the main trade route for the export of Russian petroleum. Many of the countries neighboring the Baltic Sea have been concerned about this since a major oil leak in a seagoing tanker would be disastrous for the Baltic—given the slow exchange of water. The tourism industry surrounding the Baltic Sea is naturally concerned about oil pollution. Much shipbuilding is carried out in the shipyards around the Baltic Sea. The largest shipyards are at Gdańsk, Gdynia, and Szczecin, Poland; Kiel, Germany; Karlskrona and Malmö, Sweden; Rauma, Turku, and Helsinki, Finland; Riga, Ventspils, and Liepāja, Latvia; Klaipėda, Lithuania; and Saint Petersburg, Russia. There are several cargo and passenger ferries that operate on the Baltic Sea, such as Scandlines, Silja Line, Polferries, the Viking Line, Tallink, and Superfast Ferries. Construction of the Fehmarn Belt Fixed Link between Denmark and Germany is due to finish in 2029. It will be a three-bore tunnel carrying four motorway lanes and two rail tracks. Through the development of offshore wind power the Baltic Sea is expected to become a major source of energy for countries in the region. According to the Marienborg Declaration, signed in 2022, all EU Baltic Sea states have announced their intentions to have 19.6 gigawatts of offshore wind in operation by 2030.

The 1974 Convention entered into force on 3 May 1980. 1992 Convention In the light of political changes and developments in international environmental and maritime law, a new convention was signed in 1992 by all the states bordering on the Baltic Sea, and the European Community. After ratification, the Convention entered into force on 17 January 2000. The Convention covers the whole of the Baltic Sea area, including inland waters and the water of the sea itself, as well as the seabed. Measures are also taken in the whole catchment area of the Baltic Sea to reduce land-based pollution. The convention on the Protection of the Marine Environment of the Baltic Sea Area, 1992, entered into force on 17 January 2000. The governing body of the convention is the Helsinki Commission, also known as HELCOM, or Baltic Marine Environment Protection Commission. The present contracting parties are Denmark, Estonia, the European Community, Finland, Germany, Latvia, Lithuania, Poland, Russia, and Sweden. The ratification instruments were deposited by the European Community, Germany, Latvia and Sweden in 1994, by Estonia and Finland in 1995, by Denmark in 1996, by Lithuania in 1997, and by Poland and Russia in November 1999.

BearShare

BearShare was a peer-to-peer-file-sharing-application originally created by Free Peers, Inc. for Microsoft Windows and also a rebranded version of iMesh by MusicLab, LLC, tightly integrated with their music subscription service. History The principal operators of Free Peers, Inc. were Vincent Falco and Louis Tatta. Bearshare was launched on December 4, 2000 as a Gnutella-based peer-to-peer file sharing application with innovative features that eventually grew to include IRC, a free library of software and media called BearShare Featured Artists, online help pages and a support forum integrated as dedicated web browser windows in the application; as well as a media player and a library window to organize the user's media collection. Following the June 27, 2005 United States Supreme Court decision on the MGM Studios, Inc. v. Grokster, Ltd. case the BearShare Community support forums were abruptly closed during negotiations to settle an impending lawsuit with the RIAA. The webmaster and forum administrator immediately created a new site called Technutopia and the same support staff continue to support the gnutella versions from there. A few months later the unused Community window was removed from BearShare 5.1. On May 4, 2006, Free Peers agreed to transfer all their BearShare-related assets to MusicLab, LLC (an iMesh subsidiary) and use the $30 million raised from that sale to settle with the RIAA. On August 17, 2006, MusicLab released a reskinned and updated version of iMesh named BearSharev6 which connected to its proprietary iMesh network instead of gnutella. BearShareV6 and its successors offer paid music downloads in the PlaysForSure DRM controlled WMA format as well as free content in various formats, chiefly MP3. Like BearShare they also include a media player and embedded online and social networking features but with a Web 2.0 style, somewhat similar to MySpace or Facebook. Free content provided by users is automatically verified using acoustic fingerprinting as non-infringing before it can be shared. Video files more than 50 Mb in size and 15 minutes in length cannot be shared, ensuring television shows and feature-length movies cannot be distributed over the network. Only a limited set of music and video file types can be shared, thus excluding everything else like executable files, documents and compressed archives. In August 2006, MusicLab released a variant of the original BearShare gnutella servant, called BearFlix, which was altered to limit sharing, searches and downloads to images and videos. Shared videos were limited in length and duration, similar to limits in BearShareV6. The first release was version 1.2.1. Its version numbers appear to start from 1.1.2.1 in the user interface but it presents itself on the gnutella network as versions 6.1.2.1 to 6.2.2.530. This version has since been discontinued by MusicLab and no longer available on their websites; however, it remains in wide usage. On October 27, 2008, responding to uncertainty around the future of PlaysForSure, MusicLab added iPod support in BearShareV7. As of June 12, 2016, BearShare is no longer available to download. The official page with a message announcing its discontinuation remained active until March 2017. Popular versions Three variants of the original BearShare gnutella servant were distributed by Free Peers: Free, Lite, and Pro. The Free-version had higher performance limits than the Lite version but contained some adware. The Pro version had higher limits than both the Free and Lite versions but cost US$24. Version numbers in this series ranged from 1.0 to 5.2.5.9. Though lacking MusicLab's support a wide spread of BearShare versions from 4.7 to 5.2.5.6 remain the second most popular servant on gnutella, alongside LimeWire. Old-School fans of the gnutella versions tend to favour the last of the beta versions, 5.1.0 beta25, because it has no adware, is hard-coded for performance levels roughly between Pro and regular (ad-supported) versions and has the unique ability to switch between leaf and ultrapeer mode on demand, a feature deemed necessary for effective testing. No other gnutella servant has enjoyed this capability. The most recent MusicLab version, V10, was available by free download from their support website and "Pro" features could be unlocked with a six or twelve-month subscription. Access to premium content required a $9.95 monthly subscription. Customers in Canada and the U.S.A. could opt for a $14.95 monthly "BearShare ToGo" subscription which allowed downloads of premium music to portable music players.

Belgium

Belgium, officially the Kingdom of Belgium, is a country in Northwestern Europe. The country is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the southwest, and the North Sea to the northwest. It covers an area of and has a population of more than 11.5 million, making it the 22nd most densely populated country in the world and the 6th most densely populated country in Europe, with a density of . Belgium is part of an area known as the Low Countries, historically a somewhat larger region than the Benelux group of states, as it also included parts of northern France. The capital and largest metropolitan region is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven. Belgium is a sovereign state and a federal constitutional monarchy with a parliamentary system. Its institutional organization is complex and is structured on both regional and linguistic grounds. It is divided into three highly autonomous regions: the Flemish Region (Flanders) in the north, the Walloon Region (Wallonia) in the south, and the Brussels-Capital Region. Brussels is the smallest and most densely populated region, as well as the richest region in terms of GDP per capita. Belgium is also home to two main linguistic communities: the Flemish Community, which constitutes about 60 percent of the population, and the French Community, which constitutes about 40 percent of the population. A small German-speaking Community, making up around one percent of the population, exists in the East Cantons. The Brussels-Capital Region is officially bilingual in French and Dutch, although French is the majority language and lingua franca. Belgium's linguistic diversity and related political conflicts are reflected in its complex system of governance, made up of six different governments. Since the Middle Ages, Belgium's central location has meant that the area has been relatively prosperous, connected commercially and politically to its bigger neighbours. The country as it exists today was established following the 1830 Belgian Revolution, when it seceded from the United Kingdom of the Netherlands, which had incorporated the Southern Netherlands (which comprised most of modern-day Belgium) after the Congress of Vienna in 1815. The name chosen for the new state is derived from the Latin word , used in Julius Caesar's "Gallic Wars", to describe a nearby region in the period around 55 BCE. Belgium has also been the battleground of European powers, earning the moniker "the Battlefield of Europe", a reputation reinforced in the 20th century by both world wars. Belgium participated in the Industrial Revolution, and during the course of the 20th century, possessed a number of colonies in Africa. Between 1885 and 1908, the Congo Free State, which was privately owned by King Leopold II of Belgium, was characterized by widespread atrocities and disease; amid public outcry in Europe, Belgium annexed the territory as a colony. The Belgian colonial empire gained independence between 1960 and 1962. The second half of the 20th century was marked by rising tensions between the Dutch-speaking and the French-speaking citizens fueled by differences in language and culture and the unequal economic development of Flanders and Wallonia. This continuing antagonism has led to several far-reaching state reforms, resulting in the transition from a unitary to a federal arrangement between 1970 and 1993. Despite the reforms, tensions have persisted: there is particularly significant separatist sentiment among the Flemish, language laws such as the municipalities with language facilities have been the source of much controversy, and the government formation period following the 2010 federal election set the world record at 589 days. Unemployment in Wallonia is more than double that of Flanders, which boomed after the Second World War. Belgium is a developed country, with an advanced high-income economy. The country is one of the six founding members of the European Union, and its capital, Brussels, is also the de facto capital of the European Union itself, hosting the official seats of the European Commission, the Council of the European Union, and the European Council, as well as one of two seats of the European Parliament (the other being Strasbourg). Belgium is also a founding member of the Eurozone, NATO, OECD, and WTO, and a part of the trilateral Benelux Union and the Schengen Area. Brussels also hosts the headquarters of many major international organizations, such as NATO.{{efn-ua|Belgium is a member of, or affiliated to, many international organizations, including ACCT, AfDB, AsDB, Australia Group, Benelux, BIS, CCC, CE, CERN, EAPC, EBRD, EIB, EMU, ESA, EU, FAO, G-10, IAEA, IBRD, ICAO, ICC, ICRM, IDA, IDB, IEA, IFAD, IFC, IFRCS, IHO, ILO, IMF, IMO, IMSO, Intelsat, Interpol, IOC, IOM, ISO, ITU, MONUSCO (observers), NATO, NEA, NSG, OAS (observer), OECD, OPCW, OSCE, PCA, UN, UNCTAD, UNECE, UNESCO, UNHCR, UNIDO, UNMIK, UNMOGIP, UNRWA, UNTSO, UPU, WADB (non-regional), WEU, WHO, WIPO, WMO, WTrO, ZC. History Antiquity According to Julius Caesar, the Belgae were the inhabitants of the northernmost part of Gaul. They lived in a region stretching from Paris to the Rhine, which is much bigger than modern Belgium. But he also specifically used the Latin word "Belgium", to refer to a politically dominant part of that region, which is now in northernmost France. Modern Belgium corresponds to the lands of the most northerly Belgae, the Morini, Menapii, Nervii, Germani Cisrhenani, and Aduatuci, who Caesar found particularly warlike and economically undeveloped. Caesar described this region as having strong kinship links to the Germanic tribes east of the Rhine. The area around Arlon in southern Belgium was a part of the country of the Treveri. After Caesar's conquests, Gallia Belgica came to be the Latin name of a large Roman province covering most of Northern Gaul, including the Treveri. However, areas closer to the lower Rhine frontier, including the eastern part of modern Belgium, subsequently became part of the frontier province of Germania Inferior, which continued to interact with their neighbours outside the empire. At the time when central government collapsed in the Western Roman Empire, the Roman provinces of Belgica and Germania were inhabited by a mix of a Romanized population and Germanic-speaking Franks who came to dominate the military and political class. Middle Ages During the 5th century, the area came under the rule of the Frankish Merovingian kings, who initially established a kingdom ruling over the Romanized population in what is now northern France, and then conquered the other Frankish kingdoms. During the 8th century, the empire of the Franks came to be ruled by the Carolingian dynasty, whose centre of power included the area which is now eastern Belgium. Over the centuries, it was divided up in many ways, but the Treaty of Verdun in 843 divided the Carolingian Empire into three kingdoms whose borders had a lasting impact on medieval political boundaries. Most of modern Belgium was in the Middle Kingdom, later known as Lotharingia, but the coastal county of Flanders, west of the Scheldt, became the northernmost part of West Francia, the predecessor of France. In 870 in the Treaty of Meerssen, modern Belgium lands all became part of the western kingdom for a period, but in 880 in the Treaty of Ribemont, Lotharingia came under the lasting control of the eastern kingdom, which became the Holy Roman Empire. The lordships and bishoprics along the "March" (frontier) between the two great kingdoms maintained important connections between each other. For example, the county of Flanders expanded over the Scheldt into the empire, and during several periods was ruled by the same lords as the county of Hainaut. In the 13th and 14th centuries, the cloth industry and commerce boomed especially in the County of Flanders and it became one of the richest areas in Europe. This prosperity played a role in conflicts between Flanders and the king of France. Famously, Flemish militias scored a surprise victory at the Battle of the Golden Spurs against a strong force of mounted knights in 1302, but France soon regained control of the rebellious province. Burgundian and Habsburg Netherlands In the 15th century, the Duke of Burgundy in France took control of Flanders, and from there they proceeded to unite much of what is now the Benelux, the so-called Burgundian Netherlands. "Burgundy" and "Flanders" were the first two common names used for the Burgundian Netherlands which was the predecessor of the Austrian Netherlands, the predecessor of modern Belgium. The union, technically stretching between two kingdoms, gave the area economic and political stability which led to an even greater prosperity and artistic creation. Born in Belgium, the Habsburg Emperor Charles V was heir of the Burgundians, but also of the royal families of Austria, Castile and Aragon. With the Pragmatic Sanction of 1549 he gave the Seventeen Provinces more legitimacy as a stable entity, rather than just a temporary personal union. He also increased the influence of these Netherlands over the Prince-Bishopric of Liège, which continued to exist as a large semi-independent enclave. Spanish and Austrian Netherlands The Eighty Years' War (1568–1648) was triggered by the Spanish government's policy towards Protestantism, which was becoming popular in the Low Countries. The rebellious northern United Provinces (Belgica Foederata in Latin, the "Federated Netherlands") eventually separated from the Southern Netherlands (Belgica Regia, the "Royal Netherlands"). The southern part continued to be ruled successively by the Spanish (Spanish Netherlands) and the Austrian House of Habsburgs (Austrian Netherlands) and comprised most of modern Belgium. This was the theatre of several more protracted conflicts during much of the 17th and 18th centuries involving France, including the Franco-Dutch War (1672–1678), the Nine Years' War (1688–1697), the War of the Spanish Succession (1701–1714), and part of the War of the Austrian Succession (1740–1748). French Revolution and United Kingdom of the Netherlands Following the campaigns of 1794 in the French Revolutionary Wars, the Low Countriesincluding territories that were never nominally under Habsburg rule, such as the Prince-Bishopric of Liègewere annexed by the French First Republic, ending Austrian rule in the region. A reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1814, after the abdication of Napoleon. Independent Belgium In 1830, the Belgian Revolution led to the re-separation of the Southern Provinces from the Netherlands and to the establishment of a Catholic and bourgeois, officially French-speaking and neutral, independent Belgium under a provisional government and a national congress. Since the installation of Leopold I as king on 1831, now celebrated as Belgium's National Day, Belgium has been a constitutional monarchy and parliamentary democracy, with a laicist constitution based on the Napoleonic code. Although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 (with plural voting until 1919) and for women in 1949. The main political parties of the 19th century were the Catholic Party and the Liberal Party, with the Belgian Labour Party emerging towards the end of the 19th century. French was originally the official language used by the nobility and the bourgeoisie, especially after the rejection of the Dutch monarchy. French progressively lost its dominance as Dutch began to recover its status. This recognition became official in 1898, and in 1967, the parliament accepted a Dutch version of the Constitution. The Berlin Conference of 1885 ceded control of the Congo Free State to King Leopold II as his private possession. From around 1900 there was growing international concern for the extreme and savage treatment of the Congolese population under Leopold II, for whom the Congo was primarily a source of revenue from ivory and rubber production. Many Congolese were killed by Leopold's agents for failing to meet production quotas for ivory and rubber. In 1908, this outcry led the Belgian state to assume responsibility for the government of the colony, henceforth called the Belgian Congo. A Belgian commission in 1919 estimated that Congo's population was half what it was in 1879. Germany invaded Belgium in August 1914 as part of the Schlieffen Plan to attack France, and much of the Western Front fighting of World War I occurred in western parts of the country. The opening months of the war were known as the Rape of Belgium due to German excesses. Belgium assumed control of the German colonies of Ruanda-Urundi (modern-day Rwanda and Burundi) during the war, and in 1924 the League of Nations mandated them to Belgium. In the aftermath of the First World War, Belgium annexed the Prussian districts of Eupen and Malmedy in 1925, thereby causing the presence of a German-speaking minority. German forces again invaded the country in May 1940, and 40,690 Belgians, over half of them Jews, were killed during the subsequent occupation and the Holocaust. From September 1944 to February 1945 the Allies liberated Belgium. After World War II, a general strike forced King Leopold III to abdicate in 1951 in favour of his son, Prince Baudouin, since many Belgians thought he had collaborated with Germany during the war. The Belgian Congo gained independence in 1960 during the Congo Crisis; Ruanda-Urundi followed with its independence two years later. Belgium joined NATO as a founding member and formed the Benelux group of nations with the Netherlands and Luxembourg. Belgium became one of the six founding members of the European Coal and Steel Community in 1951 and of the European Atomic Energy Community and European Economic Community, established in 1957. The latter has now become the European Union, for which Belgium hosts major administrations and institutions, including the European Commission, the Council of the European Union and the extraordinary and committee sessions of the European Parliament. In the early 1990s, Belgium saw several large corruption scandals notably surrounding Marc Dutroux, Andre Cools, the Dioxin Affair, Agusta Scandal and the murder of Karel van Noppen. Geography Belgium shares borders with France (), Germany (), Luxembourg () and the Netherlands (). Its total surface, including water area, is . Before 2018, its total area was believed to be . However, when the country's statistics were measured in 2018, a new calculation method was used. Unlike previous calculations, this one included the area from the coast to the low-water line, revealing the country to be larger in surface area than previously thought. Its land area alone is 30,446 square kilometers. It lies between latitudes 49°30' and 51°30' N, and longitudes 2°33' and 6°24' E. Belgium has three main geographical regions; the coastal plain in the northwest and the central plateau both belong to the Anglo-Belgian Basin, and the Ardennes uplands in the southeast to the Hercynian orogenic belt. The Paris Basin reaches a small fourth area at Belgium's southernmost tip, Belgian Lorraine. The coastal plain consists mainly of sand dunes and polders. Further inland lies a smooth, slowly rising landscape irrigated by numerous waterways, with fertile valleys and the northeastern sandy plain of the Campine (Kempen). The thickly forested hills and plateaus of the Ardennes are more rugged and rocky with caves and small gorges. Extending westward into France, this area is eastwardly connected to the Eifel in Germany by the High Fens plateau, on which the Signal de Botrange forms the country's highest point at . The climate is maritime temperate with significant precipitation in all seasons (Köppen climate classification: Cfb), like most of northwest Europe. The average temperature is lowest in January at and highest in July at . The average precipitation per month varies between for February and April, to for July. Averages for the years 2000 to 2006 show daily temperature minimums of and maximums of and monthly rainfall of ; these are about 1 °C and nearly 10 millimeters above last century's normal values, respectively. Phytogeographically, Belgium is shared between the Atlantic European and Central European provinces of the Circumboreal Region within the Boreal Kingdom. According to the World Wide Fund for Nature, the territory of Belgium belongs to the terrestrial ecoregions of Atlantic mixed forests and Western European broadleaf forests. Belgium had a 2018 Forest Landscape Integrity Index mean score of 1.36/10, ranking it 163rd globally out of 172 countries. Provinces The territory of Belgium is divided into three Regions, two of which, the Flemish Region and Walloon Region, are in turn subdivided into provinces; the third Region, the Brussels Capital Region, is neither a province nor a part of a province. Politics and government Belgium is a constitutional, popular monarchy and a federal parliamentary democracy. The bicameral federal parliament is composed of a Senate and a Chamber of Representatives. The former is made up of 50 senators appointed by the parliaments of the communities and regions and 10 co-opted senators. Prior to 2014, most of the Senate's members were directly elected. The Chamber's 150 representatives are elected under a proportional voting system from 11 electoral districts. Belgium has compulsory voting and thus maintains one of the highest rates of voter turnout in the world. The King (currently Philippe) is the head of state, though with limited prerogatives. He appoints ministers, including a Prime Minister, that have the confidence of the Chamber of Representatives to form the federal government. The Council of Ministers is composed of no more than fifteen members. With the possible exception of the Prime Minister, the Council of Ministers is composed of an equal number of Dutch-speaking members and French-speaking members. The judicial system is based on civil law and originates from the Napoleonic code. The Court of Cassation is the court of last resort, with the courts of appeal one level below. Political culture Belgium's political institutions are complex; most political power rests on representation of the main cultural communities. Since about 1970, the significant national Belgian political parties have split into distinct components that mainly represent the political and linguistic interests of these communities. The major parties in each community, though close to the political center, belong to three main groups: Christian Democrats, Liberals, and Social Democrats. Further notable parties came into being well after the middle of last century, mainly to represent linguistic, nationalist, or environmental interests, and recently smaller ones of some specific liberal nature. A string of Christian Democrat coalition governments from 1958 was broken in 1999 after the first dioxin crisis, a major food contamination scandal. A "rainbow coalition" emerged from six parties: the Flemish and the French-speaking Liberals, Social Democrats and Greens. Later, a "purple coalition" of Liberals and Social Democrats formed after the Greens lost most of their seats in the 2003 election. The government led by Prime Minister Guy Verhofstadt from 1999 to 2007 achieved a balanced budget, some tax reforms, a labor-market reform, scheduled nuclear phase-out and instigated legislation allowing more stringent war crime and more lenient soft drug usage prosecution. Restrictions on euthanasia were reduced and same-sex marriage was introduced. The government promoted active diplomacy in Africa and opposed the invasion of Iraq. It is the only country that does not have age restrictions on euthanasia. Verhofstadt's coalition fared badly in the June 2007 elections. For more than a year, the country experienced a political crisis. This crisis was such that many observers speculated on a possible partition of Belgium. From 2007 until 2008 the temporary Verhofstadt III Government was in office. This was a coalition of the Flemish and Francophone Christian Democrats, the Flemish and Francophone Liberals together with the Francophone Social Democrats. On that day a new government, led by Flemish Christian Democrat Yves Leterme, the actual winner of the federal elections of , was sworn in by the king. On 2008 Leterme offered the resignation of the cabinet to the king, as no progress in constitutional reforms had been made. In December 2008, Leterme once more offered his resignation after a crisis surrounding the sale of Fortis to BNP Paribas. At this juncture, his resignation was accepted and Christian Democratic and Flemish Herman Van Rompuy was sworn in as Prime Minister on 2008. After Herman Van Rompuy was designated the first permanent President of the European Council on 2009, he offered the resignation of his government to King Albert II on 2009. A few hours later, the new government under Prime Minister Yves Leterme was sworn in. On 2010, Leterme again offered the resignation of his cabinet to the king after one of the coalition partners, the OpenVLD, withdrew from the government, and on 2010 King Albert officially accepted the resignation. The Parliamentary elections in Belgium on 2010 saw the Flemish nationalist N-VA become the largest party in Flanders, and the Socialist Party PS the largest party in Wallonia. Until December 2011, Belgium was governed by Leterme's caretaker government awaiting the end of the deadlocked negotiations for formation of a new government. By 30 March 2011, this set a new world record for the elapsed time without an official government, previously held by war-torn Iraq. Finally, in December 2011 the Di Rupo Government led by Walloon socialist Prime Minister Elio Di Rupo was sworn in. The 2014 federal election (coinciding with the regional elections) resulted in a further electoral gain for the Flemish nationalist N-VA, although the incumbent coalition (composed of Flemish and French-speaking Social Democrats, Liberals, and Christian Democrats) maintains a solid majority in Parliament and in all electoral constituencies. On 22 July 2014, King Philippe nominated Charles Michel (MR) and Kris Peeters (CD&V) to lead the formation of a new federal cabinet composed of the Flemish parties N-VA, CD&V, Open Vld and the French-speaking MR, which resulted in the Michel Government. It was the first time N-VA was part of the federal cabinet, while the French-speaking side was represented only by the MR, which achieved a minority of the public votes in Wallonia. In May 2019 federal elections in the Flemish-speaking northern region of Flanders far-right Vlaams Belang party made major gains. In the French-speaking southern area of Wallonia the Socialists were strong. The moderate Flemish nationalist party the N-VA remained the largest party in parliament. In July 2019 prime minister Charles Michel was selected to hold the post of President of the European Council. His successor Sophie Wilmès was Belgium's first female prime minister. She led the caretaker government since October 2019. The Flemish Liberal party politician Alexander De Croo became new prime minister in October 2020. The parties had agreed on federal government 16 months after the elections. Communities and regions Following a usage which can be traced back to the Burgundian and Habsburg courts, in the 19th century it was necessary to speak French to belong to the governing upper class, and those who could only speak Dutch were effectively second-class citizens. Late that century, and continuing into the 20th century, Flemish movements evolved to counter this situation. While the people in Southern Belgium spoke French or dialects of French, and most Brusselers adopted French as their first language, the Flemings refused to do so and succeeded progressively in making Dutch an equal language in the education system. Following World War II, Belgian politics became increasingly dominated by the autonomy of its two main linguistic communities. Intercommunal tensions rose and the constitution was amended to minimize the potential for conflict. Based on the four language areas defined in 1962–63 (the Dutch, bilingual, French and German language areas), consecutive revisions of the country's constitution in 1970, 1980, 1988 and 1993 established a unique form of a federal state with segregated political power into three levels: The federal government, based in Brussels. The three language communities: the Flemish Community (Dutch-speaking); the French Community (French-speaking); the German-speaking Community. The three regions: the Flemish Region, subdivided into five provinces; the Walloon Region, subdivided into five provinces; the Brussels-Capital Region. The constitutional language areas determine the official languages in their municipalities, as well as the geographical limits of the empowered institutions for specific matters. Although this would allow for seven parliaments and governments when the Communities and Regions were created in 1980, Flemish politicians decided to merge both. Thus the Flemings just have one single institutional body of parliament and government is empowered for all except federal and specific municipal matters. The overlapping boundaries of the Regions and Communities have created two notable peculiarities: the territory of the Brussels-Capital Region (which came into existence nearly a decade after the other regions) is included in both the Flemish and French Communities, and the territory of the German-speaking Community lies wholly within the Walloon Region. Conflicts about jurisdiction between the bodies are resolved by the Constitutional Court of Belgium. The structure is intended as a compromise to allow different cultures to live together peacefully. Locus of policy jurisdiction The Federal State's authority includes justice, defense, federal police, social security, nuclear energy, monetary policy and public debt, and other aspects of public finances. State-owned companies include the Belgian Post Group and Belgian Railways. The Federal Government is responsible for the obligations of Belgium and its federalized institutions towards the European Union and NATO. It controls substantial parts of public health, home affairs and foreign affairs. The budget—without the debt—controlled by the federal government amounts to about 50% of the national fiscal income. The federal government employs around 12% of the civil servants. Communities exercise their authority only within linguistically determined geographical boundaries, originally oriented towards the individuals of a Community's language: culture (including audiovisual media), education and the use of the relevant language. Extensions to personal matters less directly connected with language comprise health policy (curative and preventive medicine) and assistance to individuals (protection of youth, social welfare, aid to families, immigrant assistance services, and so on.). Regions have authority in fields that can be broadly associated with their territory. These include economy, employment, agriculture, water policy, housing, public works, energy, transport, the environment, town and country planning, nature conservation, credit and foreign trade. They supervise the provinces, municipalities and intercommunal utility companies. In several fields, the different levels each have their own say on specifics. With education, for instance, the autonomy of the Communities neither includes decisions about the compulsory aspect nor allows for setting minimum requirements for awarding qualifications, which remain federal matters. Each level of government can be involved in scientific research and international relations associated with its powers. The treaty-making power of the Regions' and Communities' Governments is the broadest of all the Federating units of all the Federations all over the world. Foreign relations Because of its location at the crossroads of Western Europe, Belgium has historically been the route of invading armies from its larger neighbors. With virtually defenseless borders, Belgium has traditionally sought to avoid domination by the more powerful nations which surround it through a policy of mediation. The Belgians have been strong advocates of European integration. The headquarters of NATO and of several of the institutions of the European Union are located in Belgium. Armed forces The Belgian Armed Forces have about 47,000 active troops. In 2019, Belgium's defense budget totaled €4.303 billion ($4.921 billion) representing .93% of its GDP. They are organized into one unified structure which consists of four main components: Land Component or the Army, Air Component or the Air Force, Naval Component or the Navy and the Medical Component. The operational commands of the four components are subordinate to the Staff Department for Operations and Training of the Ministry of Defense, which is headed by the Assistant Chief of Staff Operations and Training, and to the Chief of Defense. The effects of the Second World War made collective security a priority for Belgian foreign policy. In March 1948 Belgium signed the Treaty of Brussels and then joined NATO in 1948. However, the integration of the armed forces into NATO did not begin until after the Korean War. The Belgians, along with the Luxembourg government, sent a detachment of battalion strength to fight in Korea known as the Belgian United Nations Command. This mission was the first in a long line of UN missions which the Belgians supported. Currently, the Belgian Marine Component is working closely together with the Dutch Navy under the command of the Admiral Benelux. Economy Belgium's strongly globalized economy and its transport infrastructure are integrated with the rest of Europe. Its location at the heart of a highly industrialized region helped make it the world's 15th largest trading nation in 2007. The economy is characterized by a highly productive work force, high GNP and high exports per capita. Belgium's main imports are raw materials, machinery and equipment, chemicals, raw diamonds, pharmaceuticals, foodstuffs, transportation equipment, and oil products. Its main exports are machinery and equipment, chemicals, finished diamonds, metals and metal products, and foodstuffs. The Belgian economy is heavily service-oriented and shows a dual nature: a dynamic Flemish economy and a Walloon economy that lags behind. One of the founding members of the European Union, Belgium strongly supports an open economy and the extension of the powers of EU institutions to integrate member economies. Since 1922, through the Belgium-Luxembourg Economic Union, Belgium and Luxembourg have been a single trade market with customs and currency union. Belgium was the first continental European country to undergo the Industrial Revolution, in the early 19th century. Areas in Liège Province and around Charleroi rapidly developed mining and steelmaking, which flourished until the mid-20th century in the Sambre and Meuse valley and made Belgium one of the three most industrialized nations in the world from 1830 to 1910. However, by the 1840s the textile industry of Flanders was in severe crisis, and the region experienced famine from 1846 to 1850. After World War II, Ghent and Antwerp experienced a rapid expansion of the chemical and petroleum industries. The 1973 and 1979 oil crises sent the economy into a recession; it was particularly prolonged in Wallonia, where the steel industry had become less competitive and experienced a serious decline. In the 1980s and 1990s, the economic center of the country continued to shift northwards and is now concentrated in the populous Flemish Diamond area. By the end of the 1980s, Belgian macroeconomic policies had resulted in a cumulative government debt of about 120% of GDP. , the budget was balanced and public debt was equal to 90.30% of GDP. In 2005 and 2006, real GDP growth rates of 1.5% and 3.0%, respectively, were slightly above the average for the Euro area. Unemployment rates of 8.4% in 2005 and 8.2% in 2006 were close to the area average. By , this had grown to 8.5% compared to an average rate of 9.6% for the European Union as a whole (EU 27). From 1832 until 2002, Belgium's currency was the Belgian franc. Belgium switched to the euro in 2002, with the first sets of euro coins being minted in 1999. The standard Belgian euro coins designated for circulation show the portrait of the monarch (first King Albert II, since 2013 King Philippe). Despite an 18% decrease observed from 1970 to 1999, Belgium still had in 1999 the highest rail network density within the European Union with 113.8 km/1 000 km2. On the other hand, the same period, 1970–1999, has seen a huge growth (+56%) of the motorway network. In 1999, the density of km motorways per 1000 km2 and 1000 inhabitants amounted to 55.1 and 16.5 respectively and were significantly superior to the EU's means of 13.7 and 15.9. From a biological resource perspective, Belgium has a low endowment: Belgium's biocapacity adds up to only 0.8 global hectares in 2016, just about half of the 1.6 global hectares of biocapacity available per person worldwide. In contrast, in 2016, Belgians used on average 6.3 global hectares of biocapacity - their ecological footprint of consumption. This means they required about eight times as much biocapacity as Belgium contains. As a result, Belgium was running a biocapacity deficit of 5.5 global hectares per person in 2016. Belgium experiences some of the most congested traffic in Europe. In 2010, commuters to the cities of Brussels and Antwerp spent respectively 65 and 64 hours a year in traffic jams. Like in most small European countries, more than 80% of the airways traffic is handled by a single airport, the Brussels Airport. The ports of Antwerp and Zeebrugge (Bruges) share more than 80% of Belgian maritime traffic, Antwerp being the second European harbor with a gross weight of goods handled of 115 988 000 t in 2000 after a growth of 10.9% over the preceding five years. In 2016, the port of Antwerp handled 214 million tons after a year-on-year growth of 2.7%. There is a large economic gap between Flanders and Wallonia. Wallonia was historically wealthy compared to Flanders, mostly due to its heavy industries, but the decline of the steel industry post-World War II led to the region's rapid decline, whereas Flanders rose swiftly. Since then, Flanders has been prosperous, among the wealthiest regions in Europe, whereas Wallonia has been languishing. As of 2007, the unemployment rate of Wallonia is over double that of Flanders. The divide has played a key part in the tensions between the Flemish and Walloons in addition to the already-existing language divide. Pro-independence movements have gained high popularity in Flanders as a consequence. The separatist New Flemish Alliance (N-VA) party, for instance, is the largest party in Belgium. Science and technology Contributions to the development of science and technology have appeared throughout the country's history. The 16th century Early Modern flourishing of Western Europe included cartographer Gerardus Mercator, anatomist Andreas Vesalius, herbalist Rembert Dodoens and mathematician Simon Stevin among the most influential scientists. Chemist Ernest Solvay and engineer Zenobe Gramme (École industrielle de Liège) gave their names to the Solvay process and the Gramme dynamo, respectively, in the 1860s. Bakelite was developed in 1907–1909 by Leo Baekeland. Ernest Solvay also acted as a major philanthropist and gave his name to the Solvay Institute of Sociology, the Solvay Brussels School of Economics and Management and the International Solvay Institutes for Physics and Chemistry which are now part of the Université libre de Bruxelles. In 1911, he started a series of conferences, the Solvay Conferences on Physics and Chemistry, which have had a deep impact on the evolution of quantum physics and chemistry. A major contribution to fundamental science was also due to a Belgian, Monsignor Georges Lemaître (Catholic University of Louvain), who is credited with proposing the Big Bang theory of the origin of the universe in 1927. Three Nobel Prizes in Physiology or Medicine were awarded to Belgians: Jules Bordet (Université libre de Bruxelles) in 1919, Corneille Heymans (University of Ghent) in 1938 and Albert Claude (Université libre de Bruxelles) together with Christian de Duve (Université catholique de Louvain) in 1974. François Englert (Université libre de Bruxelles) was awarded the Nobel Prize in Physics in 2013. Ilya Prigogine (Université libre de Bruxelles) was awarded the Nobel Prize in Chemistry in 1977. Two Belgian mathematicians have been awarded the Fields Medal: Pierre Deligne in 1978 and Jean Bourgain in 1994. Belgium was ranked 23rd in the Global Innovation Index in 2023. Demographics As of 1 January 2020, the total population of Belgium according to its population register was 11,492,641. The population density of Belgium is as of January 2019, making it the 22nd most densely populated country in the world, and the 6th most densely populated country in Europe. The most densely populated province is Antwerp, the least densely populated province is Luxembourg. As of January 2019, the Flemish Region had a population of 6,589,069 (57.6% of Belgium), its most populous cities being Antwerp (523,248), Ghent (260,341) and Bruges (118,284). Wallonia had a population of 3,633,795 (31.8% of Belgium) with Charleroi (201,816), Liège (197,355) and Namur (110,939), its most populous cities. The Brussels-Capital Region has 1,208,542 inhabitants (10.6% of Belgium) in the 19 municipalities, three of which have over 100,000 residents. In 2017 the average total fertility rate (TFR) across Belgium was 1.64 children per woman, below the replacement rate of 2.1; it remains considerably below the high of 4.87 children born per woman in 1873. Belgium subsequently has one of the oldest populations in the world, with an average age of 41.6 years. Migration , nearly 92% of the population had Belgian citizenship, and other European Union member citizens account for around 6%. The prevalent foreign nationals were Italian (171,918), French (125,061), Dutch (116,970), Moroccan (80,579), Portuguese (43,509), Spanish (42,765), Turkish (39,419) and German (37,621). In 2007, there were 1.38 million foreign-born residents in Belgium, corresponding to 12.9% of the total population. Of these, 685,000 (6.4%) were born outside the EU and 695,000 (6.5%) were born in another EU Member State. At the beginning of 2012, people of foreign background and their descendants were estimated to have formed around 25% of the total population i.e. 2.8 million new Belgians. Of these new Belgians, 1,200,000 are of European ancestry and 1,350,000 are from non-Western countries (most of them from Morocco, Turkey, and the DR Congo). Since the modification of the Belgian nationality law in 1984 more than 1.3 million migrants have acquired Belgian citizenship. The largest group of immigrants and their descendants in Belgium are Italian Belgians and Moroccan Belgians. 89.2% of inhabitants of Turkish origin have been naturalized, as have 88.4% of people of Moroccan background, 75.4% of Italians, 56.2% of the French and 47.8% of Dutch people. Statbel released figures of the Belgian population in relation to the origin of people in Belgium. According to the data, as of 1 January 2021, 67.3% of the Belgian population was of ethnic Belgian origin and 32.7% were of foreign origin or nationality, with 20.3% of those of a foreign nationality or ethnic group originating from neighbouring countries. The study also found that 74.5% of the Brussels Capital Region were of non-Belgian origin, of which 13.8% originated from neighbouring countries. Languages Belgium has three official languages: Dutch, French and German. A number of non-official minority languages are spoken as well. As no census exists, there are no official statistical data regarding the distribution or usage of Belgium's three official languages or their dialects. However, various criteria, including the language(s) of parents, of education, or the second-language status of foreign born, may provide suggested figures. An estimated 60% of the Belgian population are native speakers of Dutch (often referred to as Flemish), and 40% of the population speaks French natively. French-speaking Belgians are often referred to as Walloons, although the French speakers in Brussels are not Walloons. The total number of native Dutch speakers is estimated to be about 6.23 million, concentrated in the northern Flanders region, while native French speakers number 3.32 million in Wallonia and an estimated 870,000 (or 85%) in the officially bilingual Brussels-Capital Region. The German-speaking Community is made up of 73,000 people in the east of the Walloon Region; around 10,000 German and 60,000 Belgian nationals are speakers of German. Roughly 23,000 more German speakers live in municipalities near the official Community. Both Belgian Dutch and Belgian French have minor differences in vocabulary and semantic nuances from the varieties spoken respectively in the Netherlands and France. Many Flemish people still speak dialects of Dutch in their local environment. Walloon, considered either as a dialect of French or a distinct Romance language, is now only understood and spoken occasionally, mostly by elderly people. Walloon is divided into four dialects, which along with those of Picard, are rarely used in public life and have largely been replaced by French. Religion The Constitution of Belgium provides for freedom of religion, and the government respects this right in practice. Belgium officially recognizes three religions: Christianity (Catholic, Protestantism, Orthodox churches and Anglicanism), Islam and Judaism. During the reigns of Albert I and Baudouin, the Belgian royal family had a reputation of deeply rooted Catholicism. Catholicism has traditionally been Belgium's majority religion; being especially strong in Flanders. However, by 2009 Sunday church attendance was 5% for Belgium in total; 3% in Brussels, and 5.4% in Flanders. Church attendance in 2009 in Belgium was roughly half of the Sunday church attendance in 1998 (11% for the total of Belgium in 1998). Despite the drop in church attendance, Catholic identity nevertheless remains an important part of Belgium's culture. According to the Eurobarometer 2010, 37% of Belgian citizens believe in God, 31% in some sort of spirit or life-force. 27% do not believe in any sort of spirit, God, or life-force. 5% did not respond. According to the Eurobarometer 2015, 60.7% of the total population of Belgium adhered to Christianity, with Catholicism being the largest denomination with 52.9%. Protestants comprised 2.1% and Orthodox Christians were the 1.6% of the total. Non-religious people comprised 32.0% of the population and were divided between atheists (14.9%) and agnostics (17.1%). A further 5.2% of the population was Muslim and 2.1% were believers in other religions. The same survey held in 2012 found that Christianity was the largest religion in Belgium, accounting for 65% of Belgians. In the early 2000s, there were approximately 42,000 Jews in Belgium. The Jewish Community of Antwerp (numbering some 18,000) is one of the largest in Europe, and one of the last places in the world where Yiddish is the primary language of a large Jewish community (mirroring certain Orthodox and Hasidic communities in New York, New Jersey, and Israel). In addition, most Jewish children in Antwerp receive a Jewish education. There are several Jewish newspapers and more than 45 active synagogues (30 of which are in Antwerp) in the country. A 2006 inquiry in Flanders, considered to be a more religious region than Wallonia, showed that 55% considered themselves religious and that 36% believed that God created the universe. On the other hand, Wallonia has become one of Europe's most secular/least religious regions. Most of the French-speaking region's population does not consider religion an important part of their lives, and as much as 45% of the population identifies as irreligious. This is particularly the case in eastern Wallonia and areas along the French border. A 2008 estimate found that approximately 6% of the Belgian population (628,751 people) is Muslim. Muslims constitute 23.6% of the population of Brussels, 4.9% of Wallonia and 5.1% of Flanders. The majority of Belgian Muslims live in the major cities, such as Antwerp, Brussels and Charleroi. The largest group of immigrants in Belgium are Moroccans, with 400,000 people. The Turks are the third largest group, and the second largest Muslim ethnic group, numbering 220,000. Health The Belgians enjoy good health. According to 2012 estimates, the average life expectancy is 79.65 years. Since 1960, life expectancy has, in line with the European average, grown by two months per year. Death in Belgium is mainly due to heart and vascular disorders, neoplasms, disorders of the respiratory system and unnatural causes of death (accidents, suicide). Non-natural causes of death and cancer are the most common causes of death for females up to age 24 and males up to age 44. Healthcare in Belgium is financed through both social security contributions and taxation. Health insurance is compulsory. Health care is delivered by a mixed public and private system of independent medical practitioners and public, university and semi-private hospitals. Health care service are payable by the patient and reimbursed later by health insurance institutions, but for ineligible categories (of patients and services) so-called 3rd party payment systems exist. The Belgian health care system is supervised and financed by the federal government, the Flemish and Walloon Regional governments; and the German Community also has (indirect) oversight and responsibilities. For the first time in Belgian history, the first child was euthanized following the 2-year mark of the removal of the euthanization age restrictions. The child had been euthanized due to an incurable disease that was inflicted upon the child. Although there may have been some support for the euthanization there is a possibility of controversy due to the issue revolving around the subject of assisted suicide. Excluding assisted suicide, Belgium has the highest suicide rate in Western Europe and one of the highest suicide rates in the developed world (exceeded only by Lithuania, South Korea, and Latvia). Education Education is compulsory from 6 to 18 years of age for Belgians. Among OECD countries in 2002, Belgium had the third highest proportion of 18- to 21-year-olds enrolled in postsecondary education, at 42%. Though an estimated 99% of the adult population is literate, concern is rising over functional illiteracy. The Programme for International Student Assessment (PISA), coordinated by the OECD, currently ranks Belgium's education as the 19th best in the world, being significantly higher than the OECD average. Education is organized separately by each community. The Flemish Community scores noticeably above the French and German-speaking Communities. Mirroring the structure of the 19th-century Belgian political landscape, characterized by the Liberal and the Catholic parties, the educational system is segregated into secular and religious schools. The secular branch of schooling is controlled by the communities, the provinces, or the municipalities, while religious, mainly Catholic branch education, is organized by religious authorities, which are also subsidized and supervised by the communities. Culture Despite its political and linguistic divisions, the region corresponding to today's Belgium has seen the flourishing of major artistic movements that have had tremendous influence on European art and culture. Nowadays, to a certain extent, cultural life is concentrated within each language Community, and a variety of barriers have made a shared cultural sphere less pronounced. Since the 1970s, there are no bilingual universities or colleges in the country except the Royal Military Academy and the Antwerp Maritime Academy. Fine arts Contributions to painting and architecture have been especially rich. The Mosan art, the Early Netherlandish, the Flemish Renaissance and Baroque painting and major examples of Romanesque, Gothic, Renaissance and Baroque architecture are milestones in the history of art. While the 15th century's art in the Low Countries is dominated by the religious paintings of Jan van Eyck and Rogier van der Weyden, the 16th century is characterized by a broader panel of styles such as Peter Breughel's landscape paintings and Lambert Lombard's representation of the antique. Though the Baroque style of Peter Paul Rubens and Anthony van Dyck flourished in the early 17th century in the Southern Netherlands, it gradually declined thereafter. During the 19th and 20th centuries many original romantic, expressionist and surrealist Belgian painters emerged, including James Ensor and other artists belonging to the Les XX group, Constant Permeke, Paul Delvaux and René Magritte. The avant-garde CoBrA movement appeared in the 1950s, while the sculptor Panamarenko remains a remarkable figure in contemporary art. Multidisciplinary artists Jan Fabre, Wim Delvoye and the painter Luc Tuymans are other internationally renowned figures on the contemporary art scene. Belgian contributions to architecture also continued into the 19th and 20th centuries, including the work of Victor Horta and Henry van de Velde, who were major initiators of the Art Nouveau style. The vocal music of the Franco-Flemish School developed in the southern part of the Low Countries and was an important contribution to Renaissance culture. In the 19th and 20th centuries, there was an emergence of major violinists, such as Henri Vieuxtemps, Eugène Ysaÿe and Arthur Grumiaux, while Adolphe Sax invented the saxophone in 1846. The composer César Franck was born in Liège in 1822. Contemporary popular music in Belgium is also of repute. Jazz musicians Django Reinhardt and Toots Thielemans and singer Jacques Brel have achieved global fame. Nowadays, singer Stromae has been a musical revelation in Europe and beyond, having great success. In rock/pop music, Telex, Front 242, K's Choice, Hooverphonic, Zap Mama, Soulwax and dEUS are well known. In the heavy metal scene, bands like Machiavel, Channel Zero and Enthroned have a worldwide fan-base. Belgium has produced several well-known authors, including the poets Emile Verhaeren, Guido Gezelle, Robert Goffin and novelists Hendrik Conscience, Stijn Streuvels, Georges Simenon, Suzanne Lilar, Hugo Claus and Amélie Nothomb. The poet and playwright Maurice Maeterlinck won the Nobel Prize in literature in 1911. The Adventures of Tintin by Hergé is the best known of Franco-Belgian comics, but many other major authors, including Peyo (The Smurfs), André Franquin (Gaston Lagaffe), Dupa (Cubitus), Morris (Lucky Luke), Greg (Achille Talon), Lambil (Les Tuniques Bleues), Edgar P. Jacobs and Willy Vandersteen brought the Belgian cartoon strip industry a worldwide fame. Additionally, famous crime author Agatha Christie created the character Hercule Poirot, a Belgian detective, who has served as a protagonist in a number of her acclaimed mystery novels. Belgian cinema has brought a number of mainly Flemish novels to life on-screen. Other Belgian directors include André Delvaux, Stijn Coninx, Luc and Jean-Pierre Dardenne; well-known actors include Jean-Claude Van Damme, Jan Decleir and Marie Gillain; and successful films include Bullhead, Man Bites Dog and The Alzheimer Affair. Belgium is also home to a number of successful fashion designers :Category:Belgian fashion designers. Folklore Folklore plays a major role in Belgium's cultural life; the country has a comparatively high number of processions, cavalcades, parades, ommegangs, ducasses, kermesses, and other local festivals, nearly always with an originally religious or mythological background. The three-day Carnival of Binche, near Mons, with its famous Gilles (men dressed in high, plumed hats and bright costumes) is held just before Lent (the 40 days between Ash Wednesday and Easter). Together with the 'Processional Giants and Dragons' of Ath, Brussels, Dendermonde, Mechelen and Mons, it is recognized by UNESCO as a Masterpiece of the Oral and Intangible Heritage of Humanity. Other examples are the three-day Carnival of Aalst in February or March; the still very religious processions of the Holy Blood taking place in Bruges in May, the Virga Jesse procession held every seven years in Hasselt, the annual procession of Hanswijk in Mechelen, the 15 August festivities in Liège, and the Walloon festival in Namur. Originated in 1832 and revived in the 1960s, the Gentse Feesten (a music and theatre festival organized in Ghent around Belgian National Day, on 21 July) have become a modern tradition. Several of these festivals include sporting competitions, such as cycling, and many fall under the category of kermesses. A major non-official holiday (which is however not an official public holiday) is Saint Nicholas Day (Dutch: Sinterklaas, French: la Saint-Nicolas), a festivity for children, and in Liège, for students. It takes place each year on 6 December and is a sort of early Christmas. On the evening of 5 December, before going to bed, children put their shoes by the hearth with water or wine and a carrot for Saint Nicholas' horse or donkey. According to tradition, Saint Nicholas comes at night and travels down the chimney. He then takes the food and water or wine, leaves presents, goes back up, feeds his horse or donkey, and continues on his course. He also knows whether children have been good or bad. This holiday is especially loved by children in Belgium and the Netherlands. Dutch immigrants imported the tradition into the United States, where Saint Nicholas is now known as Santa Claus. Cuisine Belgium is famous for beer, chocolate, waffles and French fries. The national dishes are steak and fries, and mussels with fries. Many highly ranked Belgian restaurants can be found in the most influential restaurant guides, such as the Michelin Guide. One of the many beers with the high prestige is that of the Trappist monks. Technically, it is an ale and traditionally each abbey's beer is served in its own glass (the forms, heights and widths are different). There are only eleven breweries (six of them are Belgian) that are allowed to brew Trappist beer. Although Belgian gastronomy is connected to French cuisine, some recipes were reputedly invented there, such as French fries (despite the name, although their exact place of origin is uncertain), Flemish Carbonade (a beef stew with beer, mustard and bay laurel), speculaas (or speculoos in French, a sort of cinnamon and ginger-flavoured shortcrust biscuit), Brussels waffles (and their variant, Liège waffles), waterzooi (a broth made with chicken or fish, cream and vegetables), endive with bechamel sauce, Brussels sprouts, Belgian pralines (Belgium has some of the most renowned chocolate houses), charcuterie (deli meats) and Paling in 't groen (river eels in a sauce of green herbs). Brands of Belgian chocolate and pralines, like Côte d'Or, Neuhaus, Leonidas and Godiva are famous, as well as independent producers such as Burie and Del Rey in Antwerp and Mary's in Brussels. Belgium produces over 1100 varieties of beer. The Trappist beer of the Abbey of Westvleteren has repeatedly been rated the world's best beer. The biggest brewer in the world by volume is Anheuser-Busch InBev, based in Leuven. Sports Since the 1970s, sports clubs and federations are organized separately within each language community.

Blues

Blues is a music genre and musical form that originated in the Deep South of the United States around the 1860s. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads from the African-American culture. The blues form is ubiquitous in jazz, rhythm and blues, and rock and roll, and is characterized by the call-and-response pattern, the blues scale, and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds, fifths or sevenths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove. Blues, as a genre, is also characterized by its lyrics, bass lines, and instrumentation. Early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the AAB pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars. Early blues frequently took the form of a loose narrative, often relating the racial discrimination and other challenges experienced by African-Americans. Many elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa. The origins of the blues are also closely related to the religious music of the Afro-American community, the spirituals. The first appearance of the blues is often dated to after the ending of slavery and, later, the development of juke joints. It is associated with the newly acquired freedom of the former slaves. Chroniclers began to report about blues music at the dawn of the 20th century. The first publication of blues sheet music was in 1908. Blues has since evolved from unaccompanied vocal music and oral traditions of slaves into a wide variety of styles and subgenres. Blues subgenres include country blues, Delta blues and Piedmont blues, as well as urban blues styles such as Chicago blues and West Coast blues. World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience, especially white listeners. In the 1960s and 1970s, a hybrid form called blues rock developed, which blended blues styles with rock music. Etymology The term Blues may have originated from "blue devils", meaning melancholy and sadness. An early use of the term in this sense is in George Colman's one-act farce Blue Devils (1798). The phrase blue devils may also have been derived from a British usage of the 1600s referring to the "intense visual hallucinations that can accompany severe alcohol withdrawal." As time went on, the phrase lost the reference to devils and came to mean a state of agitation or depression. By the 1800s in the United States, the term "blues" was associated with drinking alcohol, a meaning which survives in the phrase blue law, which prohibits the sale of alcohol on Sunday. In 1827, it was in the sense of a sad state of mind that John James Audubon wrote to his wife that he "had the blues." The phrase "the blues" was written by Charlotte Forten, then aged 25, in her diary on December 14, 1862. She was a free-born black woman from Pennsylvania who was working as a schoolteacher in South Carolina, instructing both slaves and freedmen, and wrote that she "came home with the blues" because she felt lonesome and pitied herself. She overcame her depression and later noted a number of songs, such as "Poor Rosy", that were popular among the slaves. Although she admitted being unable to describe the manner of singing she heard, Forten wrote that the songs "can't be sung without a full heart and a troubled spirit," conditions that have inspired countless blues songs. Though the use of the phrase in African-American music may be older, it has been attested to in print since 1912, when Hart Wand's "Dallas Blues" became the first copyrighted blues composition. In lyrics, the phrase is often used to describe a depressed mood. Lyrics Early traditional blues verses often consisted of a single line repeated four times. However, the most common structure of blues lyrics today was established in the first few decades of the 20th century, known as the "AAB" pattern. This structure consists of a line sung over the first four bars, its repetition over the next four, and a longer concluding line over the last bars. This pattern can be heard in some of the first published blues songs, such as "Dallas Blues" (1912) and "Saint Louis Blues" (1914). According to W.C. Handy, the "AAB" pattern was adopted to avoid the monotony of lines repeated three times. The lyrics are often sung in a rhythmic talk style rather than a melody, resembling a form of talking blues. Early blues frequently took the form of a loose narrative. African-American singers voiced their "personal woes in a world of harsh reality: a lost love, the cruelty of police officers, oppression at the hands of white folk, [and] hard times". This melancholy has led to the suggestion of an Igbo origin for blues because of the reputation the Igbo had throughout plantations in the Americas for their melancholic music and outlook on life when they were enslaved. Other historians have argued that there is little evidence of Sub-Sahelian influence in the blues as "elaborate polyrhythm, percussion on African drums (as opposed to European drums), [and] collective participation" which are characteristic of West-Central African music below the savannah, are conspicuously absent. According to the historian Paul Oliver, "the roots of the blues were not to be found in the coastal and forest regions of Africa. Rather...the blues was rooted in … the savanna hinterland, from Senegambia through Mali, Burkina Faso, Northern Ghana, Niger, and northern Nigeria." Additionally, ethnomusicologist John Storm Roberts has argued that "The parallels between African savanna-belt string-playing and the techniques of many blues guitarists are remarkable. The big kora of Senegal and Guinea are played in a rhythmic-melodic style that uses constantly changing rhythms, often providing a ground bass overlaid with complex treble patterns, while vocal supplies a third rhythmic layer. Similar techniques can be found in hundreds of blues records." The lyrics often relate troubles experienced within African American society. For instance Blind Lemon Jefferson's "Rising High Water Blues" (1927) tells of the Great Mississippi Flood of 1927: Although the blues gained an association with misery and oppression, the lyrics could also be humorous and raunchy: Hokum blues celebrated both comedic lyrical content and a boisterous, farcical performance style. Tampa Red and Georgia Tom's "It's Tight Like That" (1928) is a sly wordplay with the double meaning of being "tight" with someone, coupled with a more salacious physical familiarity. Blues songs with sexually explicit lyrics were known as dirty blues. The lyrical content became slightly simpler in postwar blues, which tended to focus on relationship woes or sexual worries. Lyrical themes that frequently appeared in prewar blues, such as economic depression, farming, devils, gambling, magic, floods and drought, were less common in postwar blues. The writer Ed Morales claimed that Yoruba mythology played a part in early blues, citing Robert Johnson's "Cross Road Blues" as a "thinly veiled reference to Eleggua, the orisha in charge of the crossroads". However, the Christian influence was far more obvious. The repertoires of many seminal blues artists, such as Charley Patton and Skip James, included religious songs or spirituals. Reverend Gary Davis and Blind Willie Johnson are examples of artists often categorized as blues musicians for their music, although their lyrics clearly belong to spirituals. Form The blues form is a cyclic musical form in which a repeating progression of chords mirrors the call and response scheme commonly found in African and African-American music. During the first decades of the 20th century blues music was not clearly defined in terms of a particular chord progression. With the popularity of early performers, such as Bessie Smith, use of the twelve-bar blues spread across the music industry during the 1920s and 30s. Other chord progressions, such as 8-bar forms, are still considered blues; examples include "How Long Blues", "Trouble in Mind", and Big Bill Broonzy's "Key to the Highway". There are also 16-bar blues, such as Ray Charles's instrumental "Sweet 16 Bars" and Herbie Hancock's "Watermelon Man". Idiosyncratic numbers of bars are occasionally used, such as the 9-bar progression in "Sitting on Top of the World", by Walter Vinson. The basic 12-bar lyric framework of many blues compositions is reflected by a standard harmonic progression of 12 bars in a 4/4 time signature. The blues chords associated to a twelve-bar blues are typically a set of three different chords played over a 12-bar scheme. They are labeled by Roman numbers referring to the degrees of the progression. For instance, for a blues in the key of C, C is the tonic chord (I) and F is the subdominant (IV). The last chord is the dominant (V) turnaround, marking the transition to the beginning of the next progression. The lyrics generally end on the last beat of the tenth bar or the first beat of the 11th bar, and the final two bars are given to the instrumentalist as a break; the harmony of this two-bar break, the turnaround, can be extremely complex, sometimes consisting of single notes that defy analysis in terms of chords. Much of the time, some or all of these chords are played in the harmonic seventh (7th) form. The use of the harmonic seventh interval is characteristic of blues and is popularly called the "blues seven". Blues seven chords add to the harmonic chord a note with a frequency in a 7:4 ratio to the fundamental note. At a 7:4 ratio, it is not close to any interval on the conventional Western diatonic scale. For convenience or by necessity it is often approximated by a minor seventh interval or a dominant seventh chord. In melody, blues is distinguished by the use of the flattened third, fifth and seventh of the associated major scale. Blues shuffles or walking bass reinforce the trance-like rhythm and call-and-response, and they form a repetitive effect called a groove. Characteristic of the blues since its Afro-American origins, the shuffles played a central role in swing music. The simplest shuffles, which were the clearest signature of the R&B wave that started in the mid-1940s, were a three-note riff on the bass strings of the guitar. When this riff was played over the bass and the drums, the groove "feel" was created. Shuffle rhythm is often vocalized as "dow, da dow, da dow, da" or "dump, da dump, da dump, da": it consists of uneven, or "swung", eighth notes. On a guitar this may be played as a simple steady bass or it may add to that stepwise quarter note motion from the fifth to the sixth of the chord and back. History Origins Hart Wand's "Dallas Blues" was published in 1912; W.C. Handy's "The Memphis Blues" followed in the same year. The first recording by an African American singer was Mamie Smith's 1920 rendition of Perry Bradford's "Crazy Blues". But the origins of the blues were some decades earlier, probably around 1890. This music is poorly documented, partly because of racial discrimination in U.S. society, including academic circles, and partly because of the low rate of literacy among rural African Americans at the time. Reports of blues music in southern Texas and the Deep South were written at the dawn of the 20th century. Charles Peabody mentioned the appearance of blues music at Clarksdale, Mississippi, and Gate Thomas reported similar songs in southern Texas around 1901–1902. These observations coincide more or less with the recollections of Jelly Roll Morton, who said he first heard blues music in New Orleans in 1902; Ma Rainey, who remembered first hearing the blues in the same year in Missouri; and W.C. Handy, who first heard the blues in Tutwiler, Mississippi, in 1903. The first extensive research in the field was performed by Howard W. Odum, who published an anthology of folk songs from Lafayette County, Mississippi, and Newton County, Georgia, between 1905 and 1908. The first noncommercial recordings of blues music, termed proto-blues by Paul Oliver, were made by Odum for research purposes at the very beginning of the 20th century. They are now lost. Other recordings that are still available were made in 1924 by Lawrence Gellert. Later, several recordings were made by Robert W. Gordon, who became head of the Archive of American Folk Songs of the Library of Congress. Gordon's successor at the library was John Lomax. In the 1930s, Lomax and his son Alan made a large number of non-commercial blues recordings that testify to the huge variety of proto-blues styles, such as field hollers and ring shouts. A record of blues music as it existed before 1920 can also be found in the recordings of artists such as Lead Belly and Henry Thomas. All these sources show the existence of many different structures distinct from twelve-, eight-, or sixteen-bar. The social and economic reasons for the appearance of the blues are not fully known. The first appearance of the blues is usually dated after the Emancipation Act of 1863, between 1860s and 1890s, a period that coincides with post-emancipation and later, the establishment of juke joints as places where African-Americans went to listen to music, dance, or gamble after a hard day's work. This period corresponds to the transition from slavery to sharecropping, small-scale agricultural production, and the expansion of railroads in the southern United States. Several scholars characterize the development of blues music in the early 1900s as a move from group performance to individualized performance. They argue that the development of the blues is associated with the newly acquired freedom of the enslaved people. According to Lawrence Levine, "there was a direct relationship between the national ideological emphasis upon the individual, the popularity of Booker T. Washington's teachings, and the rise of the blues." Levine stated that "psychologically, socially, and economically, African-Americans were being acculturated in a way that would have been impossible during slavery, and it is hardly surprising that their secular music reflected this as much as their religious music did." There are few characteristics common to all blues music, because the genre took its shape from the idiosyncrasies of individual performers. However, there are some characteristics that were present long before the creation of the modern blues. Call-and-response shouts were an early form of blues-like music; they were a "functional expression ... style without accompaniment or harmony and unbounded by the formality of any particular musical structure". A form of this pre-blues was heard in slave ring shouts and field hollers, expanded into "simple solo songs laden with emotional content". Blues has evolved from the unaccompanied vocal music and oral traditions of slaves imported from West Africa and rural blacks into a wide variety of styles and subgenres, with regional variations across the United States. Although blues (as it is now known) can be seen as a musical style based on both European harmonic structure and the African call-and-response tradition that transformed into an interplay of voice and guitar, the blues form itself bears no resemblance to the melodic styles of the West African griots. Additionally, there are theories that the four-beats-per-measure structure of the blues might have its origins in the Native American tradition of pow wow drumming. Some scholars identify strong influences on the blues from the melodic structures of certain West African musical styles of the savanna and sahel. Lucy Durran finds similarities with the melodies of the Bambara people, and to a lesser degree, the Soninke people and Wolof people, but not as much of the Mandinka people. Gerard Kubik finds similarities to the melodic styles of both the west African savanna and central Africa, both of which were sources of enslaved people. No specific African musical form can be identified as the single direct ancestor of the blues. However the call-and-response format can be traced back to the music of Africa. That blue notes predate their use in blues and have an African origin is attested to by "A Negro Love Song", by the English composer Samuel Coleridge-Taylor, from his African Suite for Piano, written in 1898, which contains blue third and seventh notes. The Diddley bow (a homemade one-stringed instrument found in parts of the American South sometimes referred to as a jitterbug or a one-string in the early twentieth century) and the banjo are African-derived instruments that may have helped in the transfer of African performance techniques into the early blues instrumental vocabulary. The banjo seems to be directly imported from West African music. It is similar to the musical instrument that griots and other Africans such as the Igbo played (called halam or akonting by African peoples such as the Wolof, Fula and Mandinka). However, in the 1920s, when country blues began to be recorded, the use of the banjo in blues music was quite marginal and limited to individuals such as Papa Charlie Jackson and later Gus Cannon. Blues music also adopted elements from the "Ethiopian airs", minstrel shows and Negro spirituals, including instrumental and harmonic accompaniment. The style also was closely related to ragtime, which developed at about the same time, though the blues better preserved "the original melodic patterns of African music". The musical forms and styles that are now considered the blues as well as modern country music arose in the same regions of the southern United States during the 19th century. Recorded blues and country music can be found as far back as the 1920s, when the record industry created the marketing categories "race music" and "hillbilly music" to sell music by blacks for blacks and by whites for whites, respectively. At the time, there was no clear musical division between "blues" and "country", except for the ethnicity of the performer, and even that was sometimes documented incorrectly by record companies. Though musicologists can now attempt to define the blues narrowly in terms of certain chord structures and lyric forms thought to have originated in West Africa, audiences originally heard the music in a far more general way: it was simply the music of the rural south, notably the Mississippi Delta. Black and white musicians shared the same repertoire and thought of themselves as "songsters" rather than blues musicians. The notion of blues as a separate genre arose during the black migration from the countryside to urban areas in the 1920s and the simultaneous development of the recording industry. Blues became a code word for a record designed to sell to black listeners. The origins of the blues are closely related to the religious music of Afro-American community, the spirituals. The origins of spirituals go back much further than the blues, usually dating back to the middle of the 18th century, when the slaves were Christianized and began to sing and play Christian hymns, in particular those of Isaac Watts, which were very popular. Before the blues gained its formal definition in terms of chord progressions, it was defined as the secular counterpart of spirituals. It was the low-down music played by rural blacks. Depending on the religious community a musician belonged to, it was more or less considered a sin to play this low-down music: blues was the devil's music. Musicians were therefore segregated into two categories: gospel singers and blues singers, guitar preachers and songsters. However, when rural black music began to be recorded in the 1920s, both categories of musicians used similar techniques: call-and-response patterns, blue notes, and slide guitars. Gospel music was nevertheless using musical forms that were compatible with Christian hymns and therefore less marked by the blues form than its secular counterpart. Pre-war blues The American sheet music publishing industry produced a great deal of ragtime music. By 1912, the sheet music industry had published three popular blues-like compositions, precipitating the Tin Pan Alley adoption of blues elements: "Baby Seals' Blues", by "Baby" Franklin Seals (arranged by Artie Matthews); "Dallas Blues", by Hart Wand; and "The Memphis Blues", by W.C. Handy. Handy was a formally trained musician, composer and arranger who helped to popularize the blues by transcribing and orchestrating blues in an almost symphonic style, with bands and singers. He became a popular and prolific composer, and billed himself as the "Father of the Blues"; however, his compositions can be described as a fusion of blues with ragtime and jazz, a merger facilitated using the Cuban habanera rhythm that had long been a part of ragtime; Handy's signature work was the "Saint Louis Blues". In the 1920s, the blues became a major element of African American and American popular music, also reaching white audiences via Handy's arrangements and the classic female blues performers. These female performers became perhaps the first African American "superstars", and their recording sales demonstrated "a huge appetite for records made by and for black people." The blues evolved from informal performances in bars to entertainment in theaters. Blues performances were organized by the Theater Owners Booking Association in nightclubs such as the Cotton Club and juke joints such as the bars along Beale Street in Memphis. Several record companies, such as the American Record Corporation, Okeh Records, and Paramount Records, began to record African-American music. As the recording industry grew, country blues performers like Bo Carter, Jimmie Rodgers, Blind Lemon Jefferson, Lonnie Johnson, Tampa Red and Blind Blake became more popular in the African American community. Kentucky-born Sylvester Weaver was in 1923 the first to record the slide guitar style, in which a guitar is fretted with a knife blade or the sawed-off neck of a bottle. The slide guitar became an important part of the Delta blues. The first blues recordings from the 1920s are categorized as a traditional, rural country blues and a more polished city or urban blues. Country blues performers often improvised, either without accompaniment or with only a banjo or guitar. Regional styles of country blues varied widely in the early 20th century. The (Mississippi) Delta blues was a rootsy sparse style with passionate vocals accompanied by slide guitar. The little-recorded Robert Johnson combined elements of urban and rural blues. In addition to Robert Johnson, influential performers of this style included his predecessors Charley Patton and Son House. Singers such as Blind Willie McTell and Blind Boy Fuller performed in the southeastern "delicate and lyrical" Piedmont blues tradition, which used an elaborate ragtime-based fingerpicking guitar technique. Georgia also had an early slide tradition, with Curley Weaver, Tampa Red, "Barbecue Bob" Hicks and James "Kokomo" Arnold as representatives of this style. The lively Memphis blues style, which developed in the 1920s and 1930s near Memphis, Tennessee, was influenced by jug bands such as the Memphis Jug Band or the Gus Cannon's Jug Stompers. Performers such as Frank Stokes, Sleepy John Estes, Robert Wilkins, Joe McCoy, Casey Bill Weldon and Memphis Minnie used a variety of unusual instruments such as washboard, fiddle, kazoo or mandolin. Memphis Minnie was famous for her virtuoso guitar style. Pianist Memphis Slim began his career in Memphis, but his distinct style was smoother and had some swing elements. Many blues musicians based in Memphis moved to Chicago in the late 1930s or early 1940s and became part of the urban blues movement. Urban blues City or urban blues styles were more codified and elaborate, as a performer was no longer within their local, immediate community, and had to adapt to a larger, more varied audience's aesthetic. Classic female urban and vaudeville blues singers were popular in the 1920s, among them "the big three"—Gertrude "Ma" Rainey, Bessie Smith, and Lucille Bogan. Mamie Smith, more a vaudeville performer than a blues artist, was the first African American to record a blues song, in 1920; her second record, "Crazy Blues", sold 75,000 copies in its first month. Ma Rainey, the "Mother of Blues", and Bessie Smith each "[sang] around center tones, perhaps in order to project her voice more easily to the back of a room". Smith would "sing a song in an unusual key, and her artistry in bending and stretching notes with her beautiful, powerful contralto to accommodate her own interpretation was unsurpassed". In 1920, the vaudeville singer Lucille Hegamin became the second black woman to record blues when she recorded "The Jazz Me Blues", and Victoria Spivey, sometimes called Queen Victoria or Za Zu Girl, had a recording career that began in 1926 and spanned forty years. These recordings were typically labeled "race records" to distinguish them from records sold to white audiences. Nonetheless, the recordings of some of the classic female blues singers were purchased by white buyers as well. These blueswomen's contributions to the genre included "increased improvisation on melodic lines, unusual phrasing which altered the emphasis and impact of the lyrics, and vocal dramatics using shouts, groans, moans, and wails. The blues women thus effected changes in other types of popular singing that had spin-offs in jazz, Broadway musicals, torch songs of the 1930s and 1940s, gospel, rhythm and blues, and eventually rock and roll." Urban male performers included popular black musicians of the era, such as Tampa Red, Big Bill Broonzy and Leroy Carr. An important label of this era was the Chicago-based Bluebird Records. Before World War II, Tampa Red was sometimes referred to as "the Guitar Wizard". Carr accompanied himself on the piano with Scrapper Blackwell on guitar, a format that continued well into the 1950s with artists such as Charles Brown and even Nat "King" Cole. Boogie-woogie was another important style of 1930s and early 1940s urban blues. While the style is often associated with solo piano, boogie-woogie was also used to accompany singers and, as a solo part, in bands and small combos. Boogie-woogie style was characterized by a regular bass figure, an ostinato or riff and shifts of level in the left hand, elaborating each chord and trills and decorations in the right hand. Boogie-woogie was pioneered by the Chicago-based Jimmy Yancey and the Boogie-Woogie Trio (Albert Ammons, Pete Johnson and Meade Lux Lewis). Chicago boogie-woogie performers included Clarence "Pine Top" Smith and Earl Hines, who "linked the propulsive left-hand rhythms of the ragtime pianists with melodic figures similar to those of Armstrong's trumpet in the right hand". The smooth Louisiana style of Professor Longhair and, more recently, Dr. John blends classic rhythm and blues with blues styles. Another development in this period was big band blues. The "territory bands" operating out of Kansas City, the Bennie Moten orchestra, Jay McShann, and the Count Basie Orchestra were also concentrating on the blues, with 12-bar blues instrumentals such as Basie's "One O'Clock Jump" and "Jumpin' at the Woodside" and boisterous "blues shouting" by Jimmy Rushing on songs such as "Going to Chicago" and "Sent for You Yesterday". A well-known big band blues tune is Glenn Miller's "In the Mood". In the 1940s, the jump blues style developed. Jump blues grew up from the boogie-woogie wave and was strongly influenced by big band music. It uses saxophone or other brass instruments and the guitar in the rhythm section to create a jazzy, up-tempo sound with declamatory vocals. Jump blues tunes by Louis Jordan and Big Joe Turner, based in Kansas City, Missouri, influenced the development of later styles such as rock and roll and rhythm and blues. Dallas-born T-Bone Walker, who is often associated with the California blues style, performed a successful transition from the early urban blues à la Lonnie Johnson and Leroy Carr to the jump blues style and dominated the blues-jazz scene at Los Angeles during the 1940s. 1950s The transition from country blues to urban blues that began in the 1920s was driven by the successive waves of economic crisis and booms that led many rural blacks to move to urban areas, in a movement known as the Great Migration. The long boom following World War II induced another massive migration of the African-American population, the Second Great Migration, which was accompanied by a significant increase of the real income of the urban blacks. The new migrants constituted a new market for the music industry. The term race record, initially used by the music industry for African-American music, was replaced by the term rhythm and blues. This rapidly evolving market was mirrored by Billboard magazine's Rhythm & Blues chart. This marketing strategy reinforced trends in urban blues music such as the use of electric instruments and amplification and the generalization of the blues beat, the blues shuffle, which became ubiquitous in rhythm and blues (R&B). This commercial stream had important consequences for blues music, which, together with jazz and gospel music, became a component of R&B. After World War II, new styles of electric blues became popular in cities such as Chicago, Memphis, Detroit and St. Louis. Electric blues used electric guitars, double bass (gradually replaced by bass guitar), drums, and harmonica (or "blues harp") played through a microphone and a PA system or an overdriven guitar amplifier. Chicago became a center for electric blues from 1948 on, when Muddy Waters recorded his first success, "I Can't Be Satisfied". Chicago blues is influenced to a large extent by Delta blues, because many performers had migrated from the Mississippi region. Howlin' Wolf, Muddy Waters, Willie Dixon and Jimmy Reed were all born in Mississippi and moved to Chicago during the Great Migration. Their style is characterized by the use of electric guitar, sometimes slide guitar, harmonica, and a rhythm section of bass and drums. The saxophonist J. T. Brown played in bands led by Elmore James and by J. B. Lenoir, but the saxophone was used as a backing instrument for rhythmic support more than as a lead instrument. Little Walter, Sonny Boy Williamson (Rice Miller) and Sonny Terry are well known harmonica (called "harp" by blues musicians) players of the early Chicago blues scene. Other harp players such as Big Walter Horton were also influential. Muddy Waters and Elmore James were known for their innovative use of slide electric guitar. Howlin' Wolf and Muddy Waters were known for their deep, "gravelly" voices. The bassist and prolific songwriter and composer Willie Dixon played a major role on the Chicago blues scene. He composed and wrote many standard blues songs of the period, such as "Hoochie Coochie Man", "I Just Want to Make Love to You" (both penned for Muddy Waters) and, "Wang Dang Doodle" and "Back Door Man" for Howlin' Wolf. Most artists of the Chicago blues style recorded for the Chicago-based Chess Records and Checker Records labels. Smaller blues labels of this era included Vee-Jay Records and J.O.B. Records. During the early 1950s, the dominating Chicago labels were challenged by Sam Phillips' Sun Records company in Memphis, which recorded B. B. King and Howlin' Wolf before he moved to Chicago in 1960. After Phillips discovered Elvis Presley in 1954, the Sun label turned to the rapidly expanding white audience and started recording mostly rock 'n' roll. In the 1950s, blues had a huge influence on mainstream American popular music. While popular musicians like Bo Diddley and Chuck Berry, both recording for Chess, were influenced by the Chicago blues, their enthusiastic playing styles departed from the melancholy aspects of blues. Chicago blues also influenced Louisiana's zydeco music, with Clifton Chenier using blues accents. Zydeco musicians used electric solo guitar and cajun arrangements of blues standards. In England, electric blues took root there during a much acclaimed Muddy Waters tour in 1958. Waters, unsuspecting of his audience's tendency towards skiffle, an acoustic, softer brand of blues, turned up his amp and started to play his Chicago brand of electric blues. Although the audience was largely jolted by the performance, the performance influenced local musicians such as Alexis Korner and Cyril Davies to emulate this louder style, inspiring the British Invasion of the Rolling Stones and the Yardbirds. In the late 1950s, a new blues style emerged on Chicago's West Side pioneered by Magic Sam, Buddy Guy and Otis Rush on Cobra Records. The "West Side sound" had strong rhythmic support from a rhythm guitar, bass guitar and drums and as perfected by Guy, Freddie King, Magic Slim and Luther Allison was dominated by amplified electric lead guitar. Expressive guitar solos were a key feature of this music. Other blues artists, such as John Lee Hooker, had influences not directly related to the Chicago style. John Lee Hooker's blues is more "personal", based on Hooker's deep rough voice accompanied by a single electric guitar. Though not directly influenced by boogie-woogie, his "groovy" style is sometimes called "guitar boogie". His first hit, "Boogie Chillen", reached number 1 on the R&B charts in 1949. By the late 1950s, the swamp blues genre developed near Baton Rouge, with performers such as Lightnin' Slim, Slim Harpo, Sam Myers and Jerry McCain around the producer J. D. "Jay" Miller and the Excello label. Strongly influenced by Jimmy Reed, swamp blues has a slower pace and a simpler use of the harmonica than the Chicago blues style performers such as Little Walter or Muddy Waters. Songs from this genre include "Scratch my Back", "She's Tough" and "I'm a King Bee". Alan Lomax's recordings of Mississippi Fred McDowell would eventually bring him wider attention on both the blues and folk circuit, with McDowell's droning style influencing North Mississippi hill country blues musicians. 1960s and 1970s By the beginning of the 1960s, genres influenced by African American music such as rock and roll and soul were part of mainstream popular music. White performers such as the Rolling Stones and the Beatles had brought African-American music to new audiences, within the U.S. and abroad. However, the blues wave that brought artists such as Muddy Waters to the foreground had stopped. Bluesmen such as Big Bill Broonzy and Willie Dixon started looking for new markets in Europe. Dick Waterman and the blues festivals he organized in Europe played a major role in propagating blues music abroad. In the UK, bands emulated U.S. blues legends, and UK blues rock-based bands had an influential role throughout the 1960s. Blues performers such as John Lee Hooker and Muddy Waters continued to perform to enthusiastic audiences, inspiring new artists steeped in traditional blues, such as New York–born Taj Mahal. John Lee Hooker blended his blues style with rock elements and playing with younger white musicians, creating a musical style that can be heard on the 1971 album Endless Boogie. B. B. King's singing and virtuoso guitar technique earned him the eponymous title "king of the blues". King introduced a sophisticated style of guitar soloing based on fluid string bending and shimmering vibrato that influenced many later electric blues guitarists. In contrast to the Chicago style, King's band used strong brass support from a saxophone, trumpet, and trombone, instead of using slide guitar or harp. Tennessee-born Bobby "Blue" Bland, like B. B. King, also straddled the blues and R&B genres. During this period, Freddie King and Albert King often played with rock and soul musicians (Eric Clapton and Booker T & the MGs) and had a major influence on those styles of music. The music of the civil rights movement and Free Speech Movement in the U.S. prompted a resurgence of interest in American roots music and early African American music. As well festivals such as the Newport Folk Festival brought traditional blues to a new audience, which helped to revive interest in prewar acoustic blues and performers such as Son House, Mississippi John Hurt, Skip James, and Reverend Gary Davis. Many compilations of classic prewar blues were republished by the Yazoo Records. J. B. Lenoir from the Chicago blues movement in the 1950s recorded several LPs using acoustic guitar, sometimes accompanied by Willie Dixon on the acoustic bass or drums. His songs, originally distributed only in Europe, commented on political issues such as racism or Vietnam War issues, which was unusual for this period. His album Alabama Blues contained a song with the following lyric: White audiences' interest in the blues during the 1960s increased due to the Chicago-based Paul Butterfield Blues Band featuring guitarist Michael Bloomfield and singer/songwriter Nick Gravenites, and the British blues movement. The style of British blues developed in the UK, when musicians such as Cyril Davies, Alexis Korner's Blues Incorporated, Fleetwood Mac, John Mayall & the Bluesbreakers, the Rolling Stones, Animals, the Yardbirds, Aynsley Dunbar Retaliation, Chicken Shack, early Jethro Tull, Cream and the Irish musician Rory Gallagher performed classic blues songs from the Delta or Chicago blues traditions. In 1963, Amiri Baraka, then known as LeRoi Jones, was the first to write a book on the social history of the blues in Blues People: The Negro Music in White America. The British and blues musicians of the early 1960s inspired a number of American blues rock performers, including Canned Heat, Janis Joplin, Johnny Winter, the J. Geils Band, Ry Cooder, and the Allman Brothers Band. One blues rock performer, Jimi Hendrix, was a rarity in his field at the time: a Black man who played psychedelic rock. Hendrix was a skilled guitarist, and a pioneer in the innovative use of distortion and audio feedback in his music. Through these artists and others, blues music influenced the development of rock music. Later in the 1960s, British singer Jo Ann Kelly started her recording career. In the US, from the 1970s, female singers Bonnie Raitt and Phoebe Snow performed blues. In the early 1970s, the Texas rock-blues style emerged, which used guitars in both solo and rhythm roles. In contrast with the West Side blues, the Texas style is strongly influenced by the British rock-blues movement. Major artists of the Texas style are Johnny Winter, Stevie Ray Vaughan, the Fabulous Thunderbirds (led by harmonica player and singer-songwriter Kim Wilson), and ZZ Top. These artists all began their musical careers in the 1970s but they did not achieve international success until the next decade. 1980s to the present Since the 1980s there has been a resurgence of interest in the blues among a certain part of the African-American population, particularly around Jackson, Mississippi and other deep South regions. Often termed "soul blues" or "Southern soul", the music at the heart of this movement was given new life by the unexpected success of two particular recordings on the Jackson-based Malaco label: Z. Z. Hill's Down Home Blues (1982) and Little Milton's The Blues is Alright (1984). Contemporary African-American performers who work in this style of the blues include Bobby Rush, Denise LaSalle, Sir Charles Jones, Bettye LaVette, Marvin Sease, Peggy Scott-Adams, Mel Waiters, Clarence Carter, Dr. "Feelgood" Potts, O.B. Buchana, Ms. Jody, Shirley Brown, and dozens of others. During the 1980s blues also continued in both traditional and new forms. In 1986 the album Strong Persuader announced Robert Cray as a major blues artist. The first Stevie Ray Vaughan recording Texas Flood was released in 1983, and the Texas-based guitarist exploded onto the international stage. John Lee Hooker's popularity was revived with the album The Healer in 1989. Eric Clapton, known for his performances with the Blues Breakers and Cream, made a comeback in the 1990s with his album Unplugged, in which he played some standard blues numbers on acoustic guitar. However, beginning in the 1990s, digital multitrack recording and other technological advances and new marketing strategies including video clip production increased costs, challenging the spontaneity and improvisation that are an important component of blues music. In the 1980s and 1990s, blues publications such as Living Blues and Blues Revue were launched, major cities began forming blues societies, outdoor blues festivals became more common, and more nightclubs and venues for blues emerged. Tedeschi Trucks Band and Gov't Mule released blues rock albums. Female blues singers such as Bonnie Raitt, Susan Tedeschi, Sue Foley and Shannon Curfman also recorded albums. In the 1990s, the largely ignored hill country blues gained minor recognition in both blues and alternative rock music circles with northern Mississippi artists R. L. Burnside and Junior Kimbrough. Blues performers explored a range of musical genres, as can be seen, for example, from the broad array of nominees of the yearly Blues Music Awards, previously named W.C. Handy Awards or of the Grammy Awards for Best Contemporary and Traditional Blues Album. The Billboard Blues Album chart provides an overview of current blues hits. Contemporary blues music is nurtured by several blues labels such as: Alligator Records, Ruf Records, Severn Records, Chess Records (MCA), Delmark Records, NorthernBlues Music, Fat Possum Records and Vanguard Records (Artemis Records). Some labels are famous for rediscovering and remastering blues rarities, including Arhoolie Records, Smithsonian Folkways Recordings (heir of Folkways Records), and Yazoo Records (Shanachie Records). Musical impact Blues musical styles, forms (12-bar blues), melodies, and the blues scale have influenced many other genres of music, such as rock and roll, jazz, and popular music. Prominent jazz, folk or rock performers, such as Louis Armstrong, Duke Ellington, Miles Davis, and Bob Dylan have performed significant blues recordings. The blues scale is often used in popular songs like Harold Arlen's "Blues in the Night", blues ballads like "Since I Fell for You" and "Please Send Me Someone to Love", and even in orchestral works such as George Gershwin's "Rhapsody in Blue" and "Concerto in F". Gershwin's second "Prelude" for solo piano is an interesting example of a classical blues, maintaining the form with academic strictness. The blues scale is ubiquitous in modern popular music and informs many modal frames, especially the ladder of thirds used in rock music (for example, in "A Hard Day's Night"). Blues forms are used in the theme to the televised Batman, teen idol Fabian Forte's hit, "Turn Me Loose", country music star Jimmie Rodgers' music, and guitarist/vocalist Tracy Chapman's hit "Give Me One Reason". Early country bluesmen such as Skip James, Charley Patton, Georgia Tom Dorsey played country and urban blues and had influences from spiritual singing. Dorsey helped to popularize Gospel music. Gospel music developed in the 1930s, with the Golden Gate Quartet. In the 1950s, soul music by Sam Cooke, Ray Charles and James Brown used gospel and blues music elements. In the 1960s and 1970s, gospel and blues were merged in soul blues music. Funk music of the 1970s was influenced by soul; funk can be seen as an antecedent of hip-hop and contemporary R&B. R&B music can be traced back to spirituals and blues. Musically, spirituals were a descendant of New England choral traditions, and in particular of Isaac Watts's hymns, mixed with African rhythms and call-and-response forms. Spirituals or religious chants in the African-American community are much better documented than the "low-down" blues. Spiritual singing developed because African-American communities could gather for mass or worship gatherings, which were called camp meetings. Edward P. Comentale has noted how the blues was often used as a medium for art or self-expression, stating: "As heard from Delta shacks to Chicago tenements to Harlem cabarets, the blues proved—despite its pained origins—a remarkably flexible medium and a new arena for the shaping of identity and community." Before World War II, the boundaries between blues and jazz were less clear. Usually, jazz had harmonic structures stemming from brass bands, whereas blues had blues forms such as the 12-bar blues. However, the jump blues of the 1940s mixed both styles. After WWII, blues had a substantial influence on jazz. Bebop classics, such as Charlie Parker's "Now's the Time", used the blues form with the pentatonic scale and blue notes. Bebop marked a major shift in the role of jazz, from a popular style of music for dancing to a "high-art", less-accessible, cerebral "musician's music". The audience for both blues and jazz split, and the border between blues and jazz became more defined. The blues' 12-bar structure and the blues scale was a major influence on rock and roll music. Rock and roll has been called "blues with a backbeat"; Carl Perkins called rockabilly "blues with a country beat". Rockabillies were also said to be 12-bar blues played with a bluegrass beat. "Hound Dog", with its unmodified 12-bar structure (in both harmony and lyrics) and a melody centered on flatted third of the tonic (and flatted seventh of the subdominant), is a blues song transformed into a rock and roll song. Jerry Lee Lewis's style of rock and roll was heavily influenced by the blues and its derivative boogie-woogie. His style of music was not exactly rockabilly but it has been often called real rock and roll (this is a label he shares with several African American rock and roll performers). Many early rock and roll songs are based on blues: "That's All Right Mama", "Johnny B. Goode", "Blue Suede Shoes", "Whole Lotta Shakin' Goin On", "Shake, Rattle, and Roll", and "Long Tall Sally". The early African American rock musicians retained the sexual themes and innuendos of blues music: "Got a gal named Sue, knows just what to do" ("Tutti Frutti", Little Richard) or "See the girl with the red dress on, She can do the Birdland all night long" ("What'd I Say", Ray Charles). The 12-bar blues structure can be found even in novelty pop songs, such as Bob Dylan's "Obviously Five Believers" and Esther and Abi Ofarim's "Cinderella Rockefella". Early country music was infused with the blues. Jimmie Rodgers, Moon Mullican, Bob Wills, Bill Monroe and Hank Williams have all described themselves as blues singers and their music has a blues feel that is different, at first glance at least, from the later country-pop of artists like Eddy Arnold. Yet, if one looks back further, Arnold also started out singing bluesy songs like 'I'll Hold You in My Heart'. A lot of the 1970s-era "outlaw" country music by Willie Nelson and Waylon Jennings also borrowed from the blues. When Jerry Lee Lewis returned to country music after the decline of 1950s style rock and roll, he sang with a blues feel and often included blues standards on his albums. In popular culture Like jazz, rock and roll, heavy metal music, hip hop music, reggae, country music, Latin music, funk, and pop music, blues has been accused of being the "devil's music" and of inciting violence and other poor behavior. In the early 20th century, the blues was considered disreputable, especially as white audiences began listening to the blues during the 1920s. In the early twentieth century, W.C. Handy was the first to popularize blues-influenced music among non-Black Americans. During the blues revival of the 1960s and 1970s, acoustic blues artist Taj Mahal and Texas bluesman Lightnin' Hopkins wrote and performed music that figured prominently in the critically acclaimed film Sounder (1972). The film earned Mahal a Grammy nomination for Best Original Score Written for a Motion Picture and a BAFTA nomination. Almost 30 years later, Mahal wrote blues for, and performed a banjo composition, claw-hammer style, in the 2001 movie release Songcatcher, which focused on the story of the preservation of the roots music of Appalachia. Perhaps the most visible example of the blues style of music in the late 20th century came in 1980, when Dan Aykroyd and John Belushi released the film The Blues Brothers. The film drew many of the biggest living influencers of the rhythm and blues genre together, such as Ray Charles, James Brown, Cab Calloway, Aretha Franklin, and John Lee Hooker. The band formed also began a successful tour under the Blues Brothers marquee. 1998 brought a sequel, Blues Brothers 2000 that, while not holding as great a critical and financial success, featured a much larger number of blues artists, such as B.B. King, Bo Diddley, Erykah Badu, Eric Clapton, Steve Winwood, Charlie Musselwhite, Blues Traveler, Jimmie Vaughan, and Jeff Baxter. In 2003, Martin Scorsese made significant efforts to promote the blues to a larger audience. He asked several famous directors such as Clint Eastwood and Wim Wenders to participate in a series of documentary films for PBS called The Blues. He also participated in the rendition of compilations of major blues artists in a series of high-quality CDs. Blues guitarist and vocalist Keb' Mo' performed his blues rendition of "America, the Beautiful" in 2006 to close out the final season of the television series The West Wing. The blues was highlighted in season 2012, episode 1 of In Performance at the White House, entitled "Red, White and Blues". Hosted by Barack and Michelle Obama, the show featured performances by B.B. King, Buddy Guy, Gary Clark Jr., Jeff Beck, Derek Trucks, Keb Mo, and others.

Berlin

Berlin ( , ) is the capital and largest city of Germany by both area and population. Its more than 3.85 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the most populous urban area in Germany. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan region after the Rhine-Ruhr region. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. About one-third of the city's area is composed of forests, parks, gardens, rivers, canals, and lakes. The city lies in the Central German dialect area, the Berlin dialect being spoken. First documented in the 13th century and at the crossing of two important historic trade routes, Berlin became the capital of the Margraviate of Brandenburg (14171701), Kingdom of Prussia (1701–1918), German Empire (1871–1918), Weimar Republic (1919–1933), and Nazi Germany (1933–1945). Berlin has served as a scientific, artistic and philosophical hub of the Enlightenment, Neoclassicism, and liberal revolution. The era's industrialization-induced economic boom multiplied Berlin's population rapidly. Berlin in the roaring 1920s was the third-largest city in the world by population. After World War II and its subsequent occupation by the victorious countries, the devastated city was divided; West Berlin became a de facto exclave of West Germany, surrounded by the Berlin Wall (from August 1961 to November 1989) and East German territory. East Berlin was declared capital of East Germany, while Bonn became the West German capital. Following German reunification in 1990, Berlin once again became the capital of all of Germany. Berlin is a world city of culture, politics, media and science. Its economy is based on high-tech firms and the service sector, encompassing a diverse range of creative industries, startup companies, research facilities, media corporations, and convention venues. Berlin serves as a continental hub for air and rail traffic and has a highly complex public transportation network. The metropolis is a popular tourist destination. Significant industries also include information technology, healthcare, biomedical engineering, biotechnology, automotive, construction, electronics, social economy and clean tech. Berlin is home to world-renowned universities such as the Humboldt University, Technical University, Free University, University of the Arts, ESMT Berlin, Hertie School, and Bard College Berlin. Its Zoological Garden is the most visited zoo in Europe and one of the most popular worldwide. With Babelsberg being the world's first large-scale movie studio complex, Berlin is an increasingly popular location for international film productions. The city is well known for its festivals, diverse architecture, nightlife, contemporary arts, and high quality of life. Berlin is also home to three World Heritage Sites: Museum Island; the Palaces and Parks of Potsdam and Berlin; and the Modernism Housing Estates. Other landmarks include the Brandenburg Gate, Reichstag building, Potsdamer Platz, Memorial to the Murdered Jews of Europe, Berlin Wall Memorial, East Side Gallery, Berlin Victory Column, Berlin Cathedral, and Berlin Television Tower, the tallest structure in Germany. Berlin has numerous museums, galleries, libraries, orchestras, and sporting events including Museum Island, the German Historical Museum, Jewish Museum, Natural History Museum, State Library, State Opera, Philharmonic, and the Berlin Marathon. History Etymology Berlin lies in northeastern Germany, east of the River Elbe, that once constituted, together with the River (Saxon or Thuringian) Saale (from their confluence at Barby onwards), the eastern border of the Frankish Realm. While the Frankish Realm was primarily inhabited by Germanic tribes like the Franks and the Saxons, the regions east of the border rivers were inhabited by Slavic tribes. This is why most of the cities and villages in northeastern Germany bear Slavic-derived names (Germania Slavica). Typical Germanized place name suffixes of Slavic origin are and , prefixes are and . The name Berlin has its roots in the language of West Slavic inhabitants of the area of today's Berlin, and may be related to the Old Polabian stem ("swamp"). or Proto-Slavic bьrlogъ, (lair, den). Since the Ber- at the beginning sounds like the German word ("bear"), a bear appears in the coat of arms of the city. It is therefore an example of canting arms. Of Berlin's twelve boroughs, five bear a (partly) Slavic-derived name: Pankow (the most populous), Steglitz-Zehlendorf, Marzahn-Hellersdorf, Treptow-Köpenick and Spandau (named Spandow until 1878). Of its ninety-six neighborhoods, twenty-two bear a (partly) Slavic-derived name: Altglienicke, Alt-Treptow, Britz, Buch, Buckow, Gatow, Karow, Kladow, Köpenick, Lankwitz, Lübars, Malchow, Marzahn, Pankow, Prenzlauer Berg, Rudow, Schmöckwitz, Spandau, Stadtrandsiedlung Malchow, Steglitz, Tegel and Zehlendorf. The neighborhood of Moabit bears a French-derived name, and Französisch Buchholz is named after the Huguenots. Prehistory of Berlin The earliest human traces in the area of modern Berlin are dated around 60,000 BC. A Mesolithic deer antler mask found in Biesdorf (Berlin) was dated around 9000 BC. During Neolithic times a large number of communities existed in the area and in the Bronze Age up to 1000 people lived in 50 villages. Early Germanic tribes took settlement from 500 BC. Slavic settlements and castles began around 750 AD. 12th to 16th centuries The earliest evidence of middle age settlements in the area of today's Berlin are remnants of a house foundation dated to 1174, found in excavations in Berlin Mitte, and a wooden beam dated from approximately 1192. The first written records of towns in the area of present-day Berlin date from the late 12th century. Spandau is first mentioned in 1197 and Köpenick in 1209, although these areas did not join Berlin until 1920. The central part of Berlin can be traced back to two towns. Cölln on the Fischerinsel is first mentioned in a 1237 document, and Berlin, across the Spree in what is now called the Nikolaiviertel, is referenced in a document from 1244. 1237 is considered the founding date of the city. The two towns over time formed close economic and social ties, and profited from the staple right on the two important trade routes Via Imperii and from Bruges to Novgorod. In 1307, they formed an alliance with a common external policy, their internal administrations still being separated. In 1415, Frederick I became the elector of the Margraviate of Brandenburg, which he ruled until 1440. During the 15th century, his successors established Berlin-Cölln as capital of the margraviate, and subsequent members of the Hohenzollern family ruled in Berlin until 1918, first as electors of Brandenburg, then as kings of Prussia, and eventually as German emperors. In 1443, Frederick II Irontooth started the construction of a new royal palace in the twin city Berlin-Cölln. The protests of the town citizens against the building culminated in 1448, in the "Berlin Indignation" ("Berliner Unwille"). This protest was not successful and the citizenry lost many of its political and economic privileges. After the royal palace was finished in 1451, it gradually came into use. From 1470, with the new elector Albrecht III Achilles, Berlin-Cölln became the new royal residence. Officially, the Berlin-Cölln palace became permanent residence of the Brandenburg electors of the Hohenzollerns from 1486, when John Cicero came to power. Berlin-Cölln, however, had to give up its status as a free Hanseatic city. In 1539, the electors and the city officially became Lutheran. 17th to 19th centuries The Thirty Years' War between 1618 and 1648 devastated Berlin. One third of its houses were damaged or destroyed, and the city lost half of its population. Frederick William, known as the "Great Elector", who had succeeded his father George William as ruler in 1640, initiated a policy of promoting immigration and religious tolerance. With the Edict of Potsdam in 1685, Frederick William offered asylum to the French Huguenots. By 1700, approximately 30 percent of Berlin's residents were French, because of the Huguenot immigration. Many other immigrants came from Bohemia, Poland, and Salzburg. Since 1618, the Margraviate of Brandenburg had been in personal union with the Duchy of Prussia. In 1701, the dual state formed the Kingdom of Prussia, as Frederick III, Elector of Brandenburg, crowned himself as king Frederick I in Prussia. Berlin became the capital of the new Kingdom, replacing Königsberg. This was a successful attempt to centralise the capital in the very far-flung state, and it was the first time the city began to grow. In 1709, Berlin merged with the four cities of Cölln, Friedrichswerder, Friedrichstadt and Dorotheenstadt under the name Berlin, "Haupt- und Residenzstadt Berlin". In 1740, Frederick II, known as Frederick the Great (1740–1786), came to power. Under the rule of Frederick II, Berlin became a center of the Enlightenment, but also, was briefly occupied during the Seven Years' War by the Russian army. Following France's victory in the War of the Fourth Coalition, Napoleon Bonaparte marched into Berlin in 1806, but granted self-government to the city. In 1815, the city became part of the new Province of Brandenburg. The Industrial Revolution transformed Berlin during the 19th century; the city's economy and population expanded dramatically, and it became the main railway hub and economic center of Germany. Additional suburbs soon developed and increased the area and population of Berlin. In 1861, neighboring suburbs including Wedding, Moabit and several others were incorporated into Berlin. In 1871, Berlin became capital of the newly founded German Empire. In 1881, it became a city district separate from Brandenburg. 20th to 21st centuries In the early 20th century, Berlin had become a fertile ground for the German Expressionist movement. In fields such as architecture, painting and cinema new forms of artistic styles were invented. At the end of the First World War in 1918, a republic was proclaimed by Philipp Scheidemann at the Reichstag building. In 1920, the Greater Berlin Act incorporated dozens of suburban cities, villages, and estates around Berlin into an expanded city. The act increased the area of Berlin from . The population almost doubled, and Berlin had a population of around four million. During the Weimar era, Berlin underwent political unrest due to economic uncertainties but also became a renowned center of the Roaring Twenties. The metropolis experienced its heyday as a major world capital and was known for its leadership roles in science, technology, arts, the humanities, city planning, film, higher education, government, and industries. Albert Einstein rose to public prominence during his years in Berlin, being awarded the Nobel Prize for Physics in 1921. In 1933, Adolf Hitler and the Nazi Party came to power. Hitler was inspired by the architecture he had experienced in Vienna, and he wished for a German Empire with a capital city that had a monumental ensemble. The National Socialist regime embarked on monumental construction projects in Berlin as a way to express their power and authority through architecture. Adolf Hitler and Albert Speer developed architectural concepts for the conversion of the city into World Capital Germania; these were never implemented. NSDAP rule diminished Berlin's Jewish community from 160,000 (one-third of all Jews in the country) to about 80,000 due to emigration between 1933 and 1939. After Kristallnacht in 1938, thousands of the city's Jews were imprisoned in the nearby Sachsenhausen concentration camp. Starting in early 1943, many were shipped to concentration camps, such as Auschwitz. Berlin hosted the 1936 Summer Olympics for which the Olympic stadium was built. During World War II, large parts of Berlin were destroyed during Allied air raids and the 1945 Battle of Berlin. The Allies dropped 67,607 tons of bombs on the city, destroying 6,427 acres of the built-up area. Around 125,000 civilians were killed. After the end of World War II in Europe in May 1945, Berlin received large numbers of refugees from the Eastern provinces. The victorious powers divided the city into four sectors, analogous to Allied-occupied Germany the sectors of the Allies of World War II (the United States, the United Kingdom, and France) formed West Berlin, while the Soviet Union formed East Berlin. All four Allies of World War II shared administrative responsibilities for Berlin. However, in 1948, when the Western Allies extended the currency reform in the Western zones of Germany to the three western sectors of Berlin, the Soviet Union imposed the Berlin Blockade on the access routes to and from West Berlin, which lay entirely inside Soviet-controlled territory. The Berlin airlift, conducted by the three western Allies, overcame this blockade by supplying food and other supplies to the city from June 1948 to May 1949. In 1949, the Federal Republic of Germany was founded in West Germany and eventually included all of the American, British and French zones, excluding those three countries' zones in Berlin, while the Marxist–Leninist German Democratic Republic was proclaimed in East Germany. West Berlin officially remained an occupied city, but it politically was aligned with the Federal Republic of Germany despite West Berlin's geographic isolation. Airline service to West Berlin was granted only to American, British and French airlines. The founding of the two German states increased Cold War tensions. West Berlin was surrounded by East German territory, and East Germany proclaimed the Eastern part as its capital, a move the western powers did not recognize. East Berlin included most of the city's historic center. The West German government established itself in Bonn. In 1961, East Germany began to build the Berlin Wall around West Berlin, and events escalated to a tank standoff at Checkpoint Charlie. West Berlin was now de facto a part of West Germany with a unique legal status, while East Berlin was de facto a part of East Germany. John F. Kennedy gave his "Ich bin ein Berliner" speech on 26 June 1963, in front of the Schöneberg city hall, located in the city's western part, underlining the US support for West Berlin. Berlin was completely divided. Although it was possible for Westerners to pass to the other side through strictly controlled checkpoints, for most Easterners, travel to West Berlin or West Germany was prohibited by the government of East Germany. In 1971, a Four-Power agreement guaranteed access to and from West Berlin by car or train through East Germany. In 1989, with the end of the Cold War and pressure from the East German population, the Berlin Wall fell on 9 November and was subsequently mostly demolished. Today, the East Side Gallery preserves a large portion of the wall. On 3 October 1990, the two parts of Germany were reunified as the Federal Republic of Germany, and Berlin again became a reunified city. Walter Momper, the mayor of West Berlin, became the first mayor of the reunified city in the interim. City-wide elections in December 1990 resulted in the first "all Berlin" mayor being elected to take office in January 1991, with the separate offices of mayors in East and West Berlin expiring by that time, and Eberhard Diepgen (a former mayor of West Berlin) became the first elected mayor of a reunited Berlin. On 18 June 1994, soldiers from the United States, France and Britain marched in a parade which was part of the ceremonies to mark the withdrawal of allied occupation troops allowing a reunified Berlin (the last Russian troops departed on 31 August, while the final departure of Western Allies forces was on 8 September 1994). On 20 June 1991, the Bundestag (German Parliament) voted to move the seat of the German capital from Bonn to Berlin, which was completed in 1999, during the chancellorship of Gerhard Schröder. Berlin's 2001 administrative reform merged several boroughs, reducing their number from 23 to 12. In 2006, the FIFA World Cup Final was held in Berlin. In a 2016 terrorist attack linked to ISIL, a truck was deliberately driven into a Christmas market next to the Kaiser Wilhelm Memorial Church, leaving 13 people dead and 55 others injured. In 2018, more than 200,000 protestors took to the streets in Berlin with demonstrations of solidarity against racism, in response to the emergence of far-right politics in Germany. Berlin Brandenburg Airport (BER) opened in 2020, nine years later than planned, with Terminal 1 coming into service at the end of October, and flights to and from Tegel Airport ending in November. Due to the fall in passenger numbers resulting from the COVID-19 pandemic, plans were announced to temporarily close BER's Terminal 5, the former Schönefeld Airport, beginning in March 2021 for up to one year. The connecting link of U-Bahn line U5 from Alexanderplatz to Hauptbahnhof, along with the new stations Rotes Rathaus and Unter den Linden, opened on 4 December 2020, with the Museumsinsel U-Bahn station expected to open around March 2021, which would complete all new works on the U5. A partial opening by the end of 2020 of the Humboldt Forum museum, housed in the reconstructed Berlin Palace, which had been announced in June, was postponed until March 2021. On 16 September 2022, the opening of the eastern wing, the last section of the Humboldt Forum museum, meant the Humboldt Forum museum was finally completed. It became Germany's currently most expensive cultural project. Berlin-Brandenburg fusion attempt The legal basis for a combined state of Berlin and Brandenburg is different from other state fusion proposals. Normally, Article 29 of the Basic Law stipulates that a state fusion requires a federal law. However, a clause added to the Basic Law in 1994, Article 118a, allows Berlin and Brandenburg to unify without federal approval, requiring a referendum and a ratification by both state parliaments. In 1996, there was an unsuccessful attempt of unifying the states of Berlin and Brandenburg. Both share a common history, dialect and culture and in 2020, there are over 225.000 residents of Brandenburg that commute to Berlin. The fusion had the near-unanimous support by a broad coalition of both state governments, political parties, media, business associations, trade unions and churches. Though Berlin voted in favor by a small margin, largely based on support in former West Berlin, Brandenburg voters disapproved of the fusion by a large margin. It failed largely due to Brandenburg voters not wanting to take on Berlin's large and growing public debt and fearing losing identity and influence to the capital. Geography Topography Berlin is in northeastern Germany, in an area of low-lying marshy woodlands with a mainly flat topography, part of the vast Northern European Plain which stretches all the way from northern France to western Russia. The Berliner Urstromtal (an ice age glacial valley), between the low Barnim Plateau to the north and the Teltow plateau to the south, was formed by meltwater flowing from ice sheets at the end of the last Weichselian glaciation. The Spree follows this valley now. In Spandau, a borough in the west of Berlin, the Spree empties into the river Havel, which flows from north to south through western Berlin. The course of the Havel is more like a chain of lakes, the largest being the Tegeler See and the Großer Wannsee. A series of lakes also feeds into the upper Spree, which flows through the Großer Müggelsee in eastern Berlin. Substantial parts of present-day Berlin extend onto the low plateaus on both sides of the Spree Valley. Large parts of the boroughs Reinickendorf and Pankow lie on the Barnim Plateau, while most of the boroughs of Charlottenburg-Wilmersdorf, Steglitz-Zehlendorf, Tempelhof-Schöneberg, and Neukölln lie on the Teltow Plateau. The borough of Spandau lies partly within the Berlin Glacial Valley and partly on the Nauen Plain, which stretches to the west of Berlin. Since 2015, the Arkenberge hills in Pankow at elevation, have been the highest point in Berlin. Through the disposal of construction debris they surpassed Teufelsberg (), which itself was made up of rubble from the ruins of the Second World War. The Müggelberge at elevation is the highest natural point and the lowest is the Spektesee in Spandau, at elevation. Climate Berlin has an oceanic climate (Köppen: Cfb) bordering on a humid continental climate (Dfb); one of the changes being the annual rainfall according to the air masses and the greater abundance during a period of the year. This type of climate features moderate summer temperatures but sometimes hot (for being semicontinental) and cold winters but not rigorous most of the time. Due to its transitional climate zones, frosts are common in winter, and there are larger temperature differences between seasons than typical for many oceanic climates. Furthermore, Berlin is classified as a temperate continental climate (Dc) under the Trewartha climate scheme, as are as the suburbs of New York City, although the Köppen system puts them in different types. Summers are warm and sometimes humid with average high temperatures of and lows of . Winters are cool with average high temperatures of and lows of . Spring and autumn are generally chilly to mild. Berlin's built-up area creates a microclimate, with heat stored by the city's buildings and pavement. Temperatures can be higher in the city than in the surrounding areas. Annual precipitation is with moderate rainfall throughout the year. Snowfall mainly occurs from December through March. The hottest month in Berlin was July 1834, with a mean temperature of and the coldest was January 1709, with a mean temperature of . The wettest month on record was July 1907, with of rainfall, whereas the driest were October 1866, November 1902, October 1908 and September 1928, all with of rainfall. Cityscape Berlin's history has left the city with a polycentric organization and a highly eclectic array of architecture and buildings. The city's appearance today has been predominantly shaped by the key role it played in Germany's history during the 20th century. All of the national governments based in Berlin the Kingdom of Prussia, the 2nd German Empire of 1871, the Weimar Republic, Nazi Germany, East Germany, as well as the reunified Germany initiated ambitious reconstruction programs, with each adding its own distinctive style to the city's architecture. Berlin was devastated by air raids, fires, and street battles during the Second World War, and many of the buildings that had survived in both East and West were demolished during the postwar period. Much of this demolition was initiated by municipal architecture programs to build new business or residential districts and the main arteries. Much ornamentation on prewar buildings was destroyed following modernist dogmas, and in both postwar systems, as well as in the reunified Berlin, many important heritage structures have been reconstructed, including the Forum Fridericianum along with, the State Opera (1955), Charlottenburg Palace (1957), the monumental buildings on Gendarmenmarkt (1980s), Kommandantur (2003) and also the project to reconstruct the baroque façades of the City Palace. Many new buildings have been inspired by their historical predecessors or the general classical style of Berlin, such as Hotel Adlon. Clusters of towers rise at various locations: Potsdamer Platz, the City West, and Alexanderplatz, the latter two delineating the former centers of East and West Berlin, with the first representing a new Berlin of the 21st century, risen from the wastes of no-man's land of the Berlin Wall. Berlin has five of the top 50 tallest buildings in Germany. Over one-third of the city area consists of green space, woodlands, and water. Berlin's second-largest and most popular park, the Großer Tiergarten, is located right in the center of the city. It covers an area of 210 hectares and stretches from Bahnhof Zoo in the City West to the Brandenburg Gate in the east. Among famous streets, Unter den Linden and Friedrichstraße are found in the city's historic heart (and were included in the former East Berlin). Some major streets in City West are Kurfürstendamm (or just Ku´damm) and Kantstraße. Architecture The Fernsehturm (TV tower) at Alexanderplatz in Mitte is among the tallest structures in the European Union at . Built in 1969, it is visible throughout most of the central districts of Berlin. The city can be viewed from its observation floor. Starting here, the Karl-Marx-Allee heads east, an avenue lined by monumental residential buildings, designed in the Socialist Classicism style. Adjacent to this area is the Rotes Rathaus (City Hall), with its distinctive red-brick architecture. In front of it is the Neptunbrunnen, a fountain featuring a mythological group of Tritons, personifications of the four main Prussian rivers, and Neptune on top of it. The Brandenburg Gate is an iconic landmark of Berlin and Germany; it stands as a symbol of eventful European history and of unity and peace. The Reichstag building is the traditional seat of the German Parliament. It was remodeled by British architect Norman Foster in the 1990s and features a glass dome over the session area, which allows free public access to the parliamentary proceedings and magnificent views of the city. The East Side Gallery is an open-air exhibition of art painted directly on the last existing portions of the Berlin Wall. It is the largest remaining evidence of the city's historical division. The Gendarmenmarkt is a neoclassical square in Berlin, the name of which derives from the headquarters of the famous Gens d'armes regiment located here in the 18th century. Two similarly designed cathedrals border it, the Französischer Dom with its observation platform and the Deutscher Dom. The Konzerthaus (Concert Hall), home of the Berlin Symphony Orchestra, stands between the two cathedrals. The Museum Island in the River Spree houses five museums built from 1830 to 1930 and is a UNESCO World Heritage site. Restoration and construction of a main entrance to all museums, as well as reconstruction of the Stadtschloss continues. Also on the island and next to the Lustgarten and palace is Berlin Cathedral, emperor William II's ambitious attempt to create a Protestant counterpart to St. Peter's Basilica in Rome. A large crypt houses the remains of some of the earlier Prussian royal family. St. Hedwig's Cathedral is Berlin's Roman Catholic cathedral. Unter den Linden is a tree-lined east–west avenue from the Brandenburg Gate to the site of the former Berliner Stadtschloss, and was once Berlin's premier promenade. Many Classical buildings line the street, and part of Humboldt University is there. Friedrichstraße was Berlin's legendary street during the Golden Twenties. It combines 20th-century traditions with the modern architecture of today's Berlin. Potsdamer Platz is an entire quarter built from scratch after the Wall came down. To the west of Potsdamer Platz is the Kulturforum, which houses the Gemäldegalerie, and is flanked by the Neue Nationalgalerie and the Berliner Philharmonie. The Memorial to the Murdered Jews of Europe, a Holocaust memorial, is to the north. The area around Hackescher Markt is home to fashionable culture, with countless clothing outlets, clubs, bars, and galleries. This includes the Hackesche Höfe, a conglomeration of buildings around several courtyards, reconstructed around 1996. The nearby New Synagogue is the center of Jewish culture. The Straße des 17. Juni, connecting the Brandenburg Gate and Ernst-Reuter-Platz, serves as the central east–west axis. Its name commemorates the uprisings in East Berlin of 17 June 1953. Approximately halfway from the Brandenburg Gate is the Großer Stern, a circular traffic island on which the Siegessäule (Victory Column) is situated. This monument, built to commemorate Prussia's victories, was relocated in 1938–39 from its previous position in front of the Reichstag. The Kurfürstendamm is home to some of Berlin's luxurious stores with the Kaiser Wilhelm Memorial Church at its eastern end on Breitscheidplatz. The church was destroyed in the Second World War and left in ruins. Nearby on Tauentzienstraße is KaDeWe, claimed to be continental Europe's largest department store. The Rathaus Schöneberg, where John F. Kennedy made his famous "Ich bin ein Berliner!" speech, is in Tempelhof-Schöneberg. West of the center, Bellevue Palace is the residence of the German President. Charlottenburg Palace, which was burnt out in the Second World War, is the largest historical palace in Berlin. The Funkturm Berlin is a lattice radio tower in the fairground area, built between 1924 and 1926. It is the only observation tower which stands on insulators and has a restaurant and an observation deck above ground, which is reachable by a windowed elevator. The Oberbaumbrücke over the Spree river is Berlin's most iconic bridge, connecting the now-combined boroughs of Friedrichshain and Kreuzberg. It carries vehicles, pedestrians, and the U1 Berlin U-Bahn line. The bridge was completed in a brick gothic style in 1896, replacing the former wooden bridge with an upper deck for the U-Bahn. The center portion was demolished in 1945 to stop the Red Army from crossing. After the war, the repaired bridge served as a checkpoint and border crossing between the Soviet and American sectors, and later between East and West Berlin. In the mid-1950s, it was closed to vehicles, and after the construction of the Berlin Wall in 1961, pedestrian traffic was heavily restricted. Following German reunification, the center portion was reconstructed with a steel frame, and U-Bahn service resumed in 1995. Demographics At the end of 2018, the city-state of Berlin had 3.75 million registered inhabitants in an area of . The city's population density was 4,206 inhabitants per km2. Berlin is the most populous city proper in the European Union. In 2019, the urban area of Berlin had about 4.5 million inhabitants. , the functional urban area was home to about 5.2 million people. The entire Berlin-Brandenburg capital region has a population of more than 6 million in an area of . In 2014, the city-state Berlin had 37,368 live births (+6.6%), a record number since 1991. The number of deaths was 32,314. Almost 2.0 million households were counted in the city. 54 percent of them were single-person households. More than 337,000 families with children under the age of 18 lived in Berlin. In 2014, the German capital registered a migration surplus of approximately 40,000 people. Nationalities National and international migration into the city has a long history. In 1685, after the revocation of the Edict of Nantes in France, the city responded with the Edict of Potsdam, which guaranteed religious freedom and tax-free status to French Huguenot refugees for ten years. The Greater Berlin Act in 1920 incorporated many suburbs and surrounding cities of Berlin. It formed most of the territory that comprises modern Berlin and increased the population from 1.9 million to 4 million. Active immigration and asylum politics in West Berlin triggered waves of immigration in the 1960s and 1970s. Berlin is home to at least 180,000 Turkish and Turkish German residents, making it the largest Turkish community outside of Turkey. In the 1990s the Aussiedlergesetze enabled immigration to Germany of some residents from the former Soviet Union. Today ethnic Germans from countries of the former Soviet Union make up the largest portion of the Russian-speaking community. The last decade experienced an influx from various Western countries and some African regions. A portion of the African immigrants have settled in the Afrikanisches Viertel. Young Germans, EU-Europeans and Israelis have also settled in the city. In December 2019, there were 777,345 registered residents of foreign nationality and another 542,975 German citizens with a "migration background" (Migrationshintergrund, MH), meaning they or one of their parents immigrated to Germany after 1955. Foreign residents of Berlin originate from about 190 countries. 48 percent of the residents under the age of 15 have a migration background in 2017. Berlin in 2009 was estimated to have 100,000 to 250,000 unregistered inhabitants. Boroughs of Berlin with a significant number of migrants or foreign born population are Mitte, Neukölln and Friedrichshain-Kreuzberg. The number of Arabic speakers in Berlin could be higher than 150,000. There are at least 40,000 Berliners with Syrian citizenship, third only behind Turkish and Polish citizens. The 2015 refugee crisis made Berlin Europe's capital of Arab culture. Berlin is among the cities in Germany that have received the biggest amount of refugees after the 2022 Russian invasion of Ukraine. As of November 2022, an estimated 85,000 Ukrainian refugees were registered in Berlin, making Berlin the most popular destination of Ukrainian refugees in Germany. There are more than 20 non-indigenous communities with a population of at least 10,000 people, including Turkish, Polish, Russian, Lebanese, Palestinian, Serbian, Italian, Indian, Bosnian, Vietnamese, American, Romanian, Bulgarian, Croatian, Chinese, Austrian, Ukrainian, French, British, Spanish, Israeli, Thai, Iranian, Egyptian and Syrian communities. Languages German is the official and predominant spoken language in Berlin. It is a West Germanic language that derives most of its vocabulary from the Germanic branch of the Indo-European language family. German is one of 24 languages of the European Union, and one of the three working languages of the European Commission. Berlinerisch or Berlinisch is not a dialect linguistically. It is spoken in Berlin and the surrounding metropolitan area. It originates from a Brandenburgish variant. The dialect is now seen more like a sociolect, largely through increased immigration and trends among the educated population to speak standard German in everyday life. The most commonly spoken foreign languages in Berlin are Turkish, Polish, English, Persian, Arabic, Italian, Bulgarian, Russian, Romanian, Kurdish, Serbo-Croatian, French, Spanish and Vietnamese. Turkish, Arabic, Kurdish, and Serbo-Croatian are heard more often in the western part due to the large Middle Eastern and former-Yugoslavian communities. Polish, English, Russian, and Vietnamese have more native speakers in East Berlin. Religion On the report of the 2011 census, approximately 37 percent of the population reported being members of a legally-recognized church or religious organization. The rest either did not belong to such an organization, or there was no information available about them. The largest religious denomination recorded in 2010 was the Protestant regional church body—the Evangelical Church of Berlin-Brandenburg-Silesian Upper Lusatia (EKBO)—a united church. EKBO is a member of the Protestant Church in Germany (EKD) and of the Union of Protestant Churches in the EKD (UEK). According to the EKBO, their membership accounted for 18.7 percent of the local population, while the Roman Catholic Church had 9.1 percent of residents registered as its members. About 2.7% of the population identify with other Christian denominations (mostly Eastern Orthodox, but also various Protestants). According to the Berlin residents register, in 2018 14.9 percent were members of the Evangelical Church, and 8.5 percent were members of the Catholic Church. The government keeps a register of members of these churches for tax purposes, because it collects church tax on behalf of the churches. It does not keep records of members of other religious organizations which may collect their own church tax, in this way. In 2009, approximately 249,000 Muslims were reported by the Office of Statistics to be members of mosques and Islamic religious organizations in Berlin, while in 2016, the newspaper Der Tagesspiegel estimated that about 350,000 Muslims observed Ramadan in Berlin. In 2019, about 437,000 registered residents, 11.6% of the total, reported having a migration background from one of the Member states of the Organization of Islamic Cooperation. Between 1992 and 2011 the Muslim population almost doubled. About 0.9% of Berliners belong to other religions. Of the estimated population of 30,000–45,000 Jewish residents, approximately 12,000 are registered members of religious organizations. Berlin is the seat of the Roman Catholic archbishop of Berlin and EKBO's elected chairperson is titled the bishop of EKBO. Furthermore, Berlin is the seat of many Orthodox cathedrals, such as the Cathedral of St. Boris the Baptist, one of the two seats of the Bulgarian Orthodox Diocese of Western and Central Europe, and the Resurrection of Christ Cathedral of the Diocese of Berlin (Patriarchate of Moscow). The faithful of the different religions and denominations maintain many places of worship in Berlin. The Independent Evangelical Lutheran Church has eight parishes of different sizes in Berlin. There are 36 Baptist congregations (within Union of Evangelical Free Church Congregations in Germany), 29 New Apostolic Churches, 15 United Methodist churches, eight Free Evangelical Congregations, four Churches of Christ, Scientist (1st, 2nd, 3rd, and 11th), six congregations of the Church of Jesus Christ of Latter-day Saints, an Old Catholic church, and an Anglican church in Berlin. Berlin has more than 80 mosques, ten synagogues, and two Buddhist temples. Government and politics City state Since reunification on 3 October 1990, Berlin has been one of the three city states in Germany among the present 16 states of Germany. The House of Representatives (Abgeordnetenhaus) functions as the city and state parliament, which has 141 seats. Berlin's executive body is the Senate of Berlin (Senat von Berlin). The Senate consists of the Governing Mayor (Regierender Bürgermeister), and up to ten senators holding ministerial positions, two of them holding the title of "Mayor" (Bürgermeister) as deputy to the Governing Mayor. The total annual state budget of Berlin in 2015 exceeded €24.5 ($30.0) billion including a budget surplus of €205 ($240) million. The state owns extensive assets, including administrative and government buildings, real estate companies, as well as stakes in the Olympic Stadium, swimming pools, housing companies, and numerous public enterprises and subsidiary companies. The Social Democratic Party (SPD) and The Left (Die Linke) took control of the city government after the 2001 state election and won another term in the 2006 state election. From the 2016 state election until the 2023 state election, there was a coalition between the Social Democratic Party, the Greens and the Left Party. Since April 2023, the government has been formed by a coalition between the Christian Democrats and the Social Democrats. The Governing Mayor is simultaneously Lord Mayor of the City of Berlin (Oberbürgermeister der Stadt) and Minister President of the State of Berlin (Ministerpräsident des Bundeslandes). The office of the Governing Mayor is in the Rotes Rathaus (Red City Hall). Since 2023, this office has been held by Kai Wegner of the Christian Democrats. He is the first conservative mayor in Berlin in more than two decades. Boroughs Berlin is subdivided into 12 boroughs or districts (Bezirke). Each borough has several subdistricts or neighborhoods (Ortsteile), which have roots in much older municipalities that predate the formation of Greater Berlin on 1 October 1920. These subdistricts became urbanized and incorporated into the city later on. Many residents strongly identify with their neighborhoods, colloquially called Kiez. At present, Berlin consists of 96 subdistricts, which are commonly made up of several smaller residential areas or quarters. Each borough is governed by a borough council (Bezirksamt) consisting of five councilors (Bezirksstadträte) including the borough's mayor (Bezirksbürgermeister). The council is elected by the borough assembly (Bezirksverordnetenversammlung). However, the individual boroughs are not independent municipalities, but subordinate to the Senate of Berlin. The borough's mayors make up the council of mayors (Rat der Bürgermeister), which is led by the city's Governing Mayor and advises the Senate. The neighborhoods have no local government bodies. Twin towns – sister cities Berlin maintains official partnerships with 17 cities. Town twinning between West Berlin and other cities began with its sister city Los Angeles, California (the 1932 and 1984 Summer Olympics host city) in 1967. East Berlin's partnerships were canceled at the time of German reunification but later partially reestablished relations in the 1990s. West Berlin's partnerships had previously been restricted to the borough level. During the Cold War, the partnerships had reflected the different power blocs, with West Berlin partnering with capitals in the Western World and East Berlin mostly partnering with cities from the Warsaw Pact and its allies. There are several joint projects with many other cities, such as Amsterdam, Beirut, Belgrade, Copenhagen, Hanoi, Helsinki, Johannesburg, Mumbai, New York City, Oslo, São Paulo, Seoul, Shanghai, Sofia, Sydney, and Vienna. Berlin participates in international city associations such as the Union of the Capitals of the European Union, Eurocities, Network of European Cities of Culture, Metropolis, Summit Conference of the World's Major Cities, and Conference of the World's Capital Cities. Berlin is twinned with: Los Angeles, United States (1967) Madrid, Spain (1988) Istanbul, Turkey (1989) Warsaw, Poland (1991) Moscow, Russia (1991) Brussels, Belgium (1992) Budapest, Hungary (1992) Tashkent, Uzbekistan (1993) Mexico City, Mexico (1993) Jakarta, Indonesia (1993) Beijing, China (1994) Tokyo, Japan (1994) Buenos Aires, Argentina (1994) Prague, Czech Republic (1995) Windhoek, Namibia (2000) London, United Kingdom (2000) Kyiv, Ukraine (2023) Since 1987, Berlin also has an official partnership with Paris, France. Every Berlin borough also established its own twin towns. For example, the borough of Friedrichshain-Kreuzberg has a partnership with the Israeli city of Kiryat Yam. Capital city Berlin is the capital of the Federal Republic of Germany. The President of Germany, whose functions are mainly ceremonial under the German constitution, has their official residence in Bellevue Palace. Berlin is the seat of the German Chancellor (Prime Minister), housed in the Chancellery building, the Bundeskanzleramt. Facing the Chancellery is the Bundestag, the German Parliament, housed in the renovated Reichstag building since the government's relocation to Berlin in 1998. The Bundesrat ("federal council", performing the function of an upper house) is the representation of the 16 constituent states (Länder) of Germany and has its seat at the former Prussian House of Lords. The total annual federal budget managed by the German government exceeded €310 ($375) billion in 2013. The relocation of the federal government and Bundestag to Berlin was mostly completed in 1999. However, some ministries, as well as some minor departments, stayed in the federal city Bonn, the former capital of West Germany. Discussions about moving the remaining ministries and departments to Berlin continue. The Federal Foreign Office and the ministries and departments of Defense, Justice and Consumer Protection, Finance, Interior, Economic Affairs and Energy, Labor and Social Affairs, Family Affairs, Senior Citizens, Women and Youth, Environment, Nature Conservation and Nuclear Safety, Food and Agriculture, Economic Cooperation and Development, Health, Transport and Digital Infrastructure and Education and Research are based in the capital. Berlin hosts in total 158 foreign embassies as well as the headquarters of many think tanks, trade unions, nonprofit organizations, lobbying groups, and professional associations. Due to the influence and international partnerships of the Federal Republic of Germany, the capital city has become a significant center of German and European affairs. Frequent official visits and diplomatic consultations among governmental representatives and national leaders are common in contemporary Berlin. Economy In 2018, the GDP of Berlin totaled €147 billion, an increase of 3.1% over the previous year. Berlin's economy is dominated by the service sector, with around 84% of all companies doing business in services. In 2015, the total labor force in Berlin was 1.85 million. The unemployment rate reached a 24-year low in November 2015 and stood at 10.0%. From 2012 to 2015 Berlin, as a German state, had the highest annual employment growth rate. Around 130,000 jobs were added in this period. Important economic sectors in Berlin include life sciences, transportation, information and communication technologies, media and music, advertising and design, biotechnology, environmental services, construction, e-commerce, retail, hotel business, and medical engineering. Research and development have economic significance for the city. Several major corporations like Volkswagen, Pfizer, and SAP operate innovation laboratories in the city. The Science and Business Park in Adlershof is the largest technology park in Germany measured by revenue. Within the Eurozone, Berlin has become a center for business relocation and international investments. Companies Many German and international companies have business or service centers in the city. For several years Berlin has been recognized as a major center of business founders. In 2015, Berlin generated the most venture capital for young startup companies in Europe. Among the 10 largest employers in Berlin are the City-State of Berlin, , the hospital providers Charité and Vivantes, the Federal Government of Germany, the local public transport provider BVG, Siemens and Deutsche Telekom. Siemens, a Global 500 and DAX-listed company is partly headquartered in Berlin. Other DAX-listed companies headquartered in Berlin are the property company Deutsche Wohnen and the online food delivery service Delivery Hero. The national railway operator , Europe's largest digital publisher Axel Springer as well as the MDAX-listed firms Zalando and HelloFresh and also have their main headquarters in the city. Among the largest international corporations who have their German or European headquarters in Berlin are Bombardier Transportation, Securing Energy for Europe, Coca-Cola, Pfizer, Sony and TotalEnergies. As of 2018, the three largest banks headquartered in the capital were Deutsche Kreditbank, Landesbank Berlin and Berlin Hyp. Mercedes-Benz Group manufactures cars, and BMW builds motorcycles in Berlin. In 2022, American electric car manufacturer Tesla opened its first European Gigafactory outside the city borders in Grünheide (Mark), Brandenburg. The Pharmaceuticals division of Bayer and Berlin Chemie are major pharmaceutical companies in the city. Tourism and conventions Berlin had 788 hotels with 134,399 beds in 2014.

Benjamin Lee Whorf

Benjamin Lee Whorf (; April 24, 1897 – July 26, 1941) was an American linguist and fire prevention engineer who is famous for proposing the "Sapir–Whorf hypothesis." He believed that the structures of different languages shape how their speakers perceive and conceptualize the world. Whorf saw this idea, named after him and his mentor Edward Sapir, as having implications similar to Einstein's principle of physical relativity. However, the concept originated from 19th-century philosophy and thinkers like Wilhelm von Humboldt and Wilhelm Wundt. Whorf initially pursued chemical engineering but developed an interest in linguistics, particularly Biblical Hebrew and indigenous Mesoamerican languages. His groundbreaking work on the Nahuatl language earned him recognition, and he received a grant to study it further in Mexico. He presented influential papers on Nahuatl upon his return. Whorf later studied linguistics with Edward Sapir at Yale University while working as a fire prevention engineer. During his time at Yale, Whorf worked on describing the Hopi language and made notable claims about its perception of time. He also conducted research on the Uto-Aztecan languages, publishing influential papers. In 1938, he substituted for Sapir, teaching a seminar on American Indian linguistics. Whorf's contributions extended beyond linguistic relativity; he wrote a grammar sketch of Hopi, studied Nahuatl dialects, proposed a deciphering of Maya hieroglyphic writing, and contributed to Uto-Aztecan reconstruction. After Whorf's death from cancer in 1941, his linguist friends curated his manuscripts and promoted his ideas regarding language, culture, and cognition. However, in the 1960s, his views fell out of favor due to criticisms claiming his ideas were untestable and poorly formulated. In recent decades, interest in Whorf's work has resurged, with scholars reevaluating his ideas and engaging in a more in-depth understanding of his theories. The field of linguistic relativity remains an active area of research in psycholinguistics and linguistic anthropology, generating ongoing debates between relativism and universalism. Whorf's contributions to linguistics, such as the allophone and the cryptotype, have been widely accepted. Biography Early life The son of Harry Church Whorf and Sarah Edna Lee Whorf, Benjamin Lee Whorf was born on April 24, 1897, in Winthrop, Massachusetts. Harry Church Whorf was an artist, intellectual, and designer – first working as a commercial artist and later as a dramatist. Whorf had two younger brothers, John and Richard, who both went on to become notable artists. John became an internationally renowned painter and illustrator; Richard was an actor in films such as Yankee Doodle Dandy and later an Emmy-nominated television director of such shows as The Beverly Hillbillies. Whorf was the intellectual of the three and started conducting chemical experiments with his father's photographic equipment at a young age. He was also an avid reader, interested in botany, astrology, and Middle American prehistory. He read William H. Prescott's Conquest of Mexico several times. At the age of 17, he began keeping a copious diary in which he recorded his thoughts and dreams. Career in fire prevention Whorf graduated from the Massachusetts Institute of Technology in 1918 with a degree in chemical engineering where his academic performance was of average quality. In 1920, he married Celia Inez Peckham, who became the mother of his three children, Raymond Ben, Robert Peckham and Celia Lee. Around the same time he began work as a fire prevention engineer (an inspector) for the Hartford Fire Insurance Company. He was particularly good at the job and was highly commended by his employers. His job required him to travel to production facilities throughout New England to be inspected. One anecdote describes him arriving at a chemical plant in which he was denied access by the director because he would not allow anyone to see the production procedure which was a trade secret. Having been told what the plant produced, Whorf wrote a chemical formula on a piece of paper, saying to the director: "I think this is what you're doing". The surprised director asked Whorf how he knew about the secret procedure, and he simply answered: "You couldn't do it in any other way." Whorf helped to attract new customers to the Fire Insurance Company; they favored his thorough inspections and recommendations. Another famous anecdote from his job was used by Whorf to argue that language use affects habitual behavior. Whorf described a workplace in which full gasoline drums were stored in one room and empty ones in another; he said that because of flammable vapor the "empty" drums were more dangerous than those that were full, although workers handled them less carefully to the point that they smoked in the room with "empty" drums, but not in the room with full ones. Whorf argued that by habitually speaking of the vapor-filled drums as empty and by extension as inert, the workers were oblivious to the risk posed by smoking near the "empty drums". Early interest in religion and language Whorf was a spiritual man throughout his lifetime although what religion he followed has been the subject of debate. As a young man, he produced a manuscript titled "Why I have discarded evolution", causing some scholars to describe him as a devout Methodist, who was impressed with fundamentalism, and perhaps supportive of creationism. However, throughout his life Whorf's main religious interest was theosophy, a nonsectarian organization based on Buddhist and Hindu teachings that promotes the view of the world as an interconnected whole and the unity and brotherhood of humankind "without distinction of race, creed, sex, caste or color". Some scholars have argued that the conflict between spiritual and scientific inclinations has been a driving force in Whorf's intellectual development, particularly in the attraction by ideas of linguistic relativity. Whorf said that "of all groups of people with whom I have come in contact, Theosophical people seem the most capable of becoming excited about ideas—new ideas." Around 1924, Whorf first became interested in linguistics. Originally, he analyzed Biblical texts, seeking to uncover hidden layers of meaning. Inspired by the esoteric work La langue hebraïque restituée by Antoine Fabre d'Olivet, he began a semantic and grammatical analysis of Biblical Hebrew. Whorf's early manuscripts on Hebrew and Maya have been described as exhibiting a considerable degree of mysticism, as he sought to uncover esoteric meanings of glyphs and letters. Early studies in Mesoamerican linguistics Whorf studied Biblical linguistics mainly at the Watkinson Library (now Hartford Public Library). This library had an extensive collection of materials about Native American linguistics and folklore, originally collected by James Hammond Trumbull. It was at the Watkinson library that Whorf became friends with the young boy, John B. Carroll, who later went on to study psychology under B. F. Skinner, and who in 1956 edited and published a selection of Whorf's essays as Language, Thought and Reality . The collection rekindled Whorf's interest in Mesoamerican antiquity. He began studying the Nahuatl language in 1925, and later, beginning in 1928, he studied the collections of Maya hieroglyphic texts. Quickly becoming conversant with the materials, he began a scholarly dialog with Mesoamericanists such as Alfred Tozzer, the Maya archaeologist at Harvard University, and Herbert Spinden of the Brooklyn Museum. In 1928, he first presented a paper at the International Congress of Americanists in which he presented his translation of a Nahuatl document held at the Peabody Museum at Harvard. He also began to study the comparative linguistics of the Uto-Aztecan language family, which Edward Sapir had recently demonstrated to be a linguistic family. In addition to Nahuatl, Whorf studied the Piman and Tepecano languages, while in close correspondence with linguist J. Alden Mason. Field studies in Mexico Because of the promise shown by his work on Uto-Aztecan, Tozzer and Spinden advised Whorf to apply for a grant with the Social Science Research Council (SSRC) to support his research. Whorf considered using the money to travel to Mexico to procure Aztec manuscripts for the Watkinson library, but Tozzer suggested he spend the time in Mexico documenting modern Nahuatl dialects. In his application Whorf proposed to establish the oligosynthetic nature of the Nahuatl language. Before leaving Whorf presented the paper "Stem series in Maya" at the Linguistic Society of America conference, in which he argued that in the Mayan languages syllables carry symbolic content. The SSRC awarded Whorf the grant and in 1930 he traveled to Mexico City, where Professor Robert H. Barlow put him in contact with several speakers of Nahuatl to serve as his informants. The outcome of the trip to Mexico was Whorf's sketch of Milpa Alta Nahuatl, published only after his death, and an article on a series of Aztec pictograms found at the Tepozteco monument at Tepoztlán, Morelos in which he noted similarities in form and meaning between Aztec and Maya day signs. At Yale Although Whorf had been entirely an autodidact in linguistic theory and field methodology up to this point, he had already made a name for himself in Mesoamerican linguistics. Whorf had met Sapir, the leading US linguist of the day, at professional conferences, and in 1931 Sapir came to Yale from the University of Chicago to take a position as Professor of Anthropology. Alfred Tozzer sent Sapir a copy of Whorf's paper on "Nahuatl tones and saltillo". Sapir replied stating that it "should by all means be published"; however, it was not until 1993 that it was prepared for publication by Lyle Campbell and Frances Karttunen. Whorf took Sapir's first course at Yale on "American Indian Linguistics". He enrolled in a program of graduate studies, nominally working towards a PhD in linguistics, but he never actually attempted to obtain a degree, satisfying himself with participating in the intellectual community around Sapir. At Yale, Whorf joined the circle of Sapir's students that included such luminaries as Morris Swadesh, Mary Haas, Harry Hoijer, G. L. Trager and Charles F. Voegelin. Whorf took on a central role among Sapir's students and was well respected. Sapir had a profound influence on Whorf's thinking. Sapir's earliest writings had espoused views of the relation between thought and language stemming from the Humboldtian tradition he acquired through Franz Boas, which regarded language as the historical embodiment of volksgeist, or ethnic world view. But Sapir had since become influenced by a current of logical positivism, such as that of Bertrand Russell and the early Ludwig Wittgenstein, particularly through Ogden and Richards' The Meaning of Meaning, from which he adopted the view that natural language potentially obscures, rather than facilitates, the mind to perceive and describe the world as it really is. In this view, proper perception could only be accomplished through formal logics. During his stay at Yale, Whorf acquired this current of thought partly from Sapir and partly through his own readings of Russell and Ogden and Richards. As Whorf became more influenced by positivist science he also distanced himself from some approaches to language and meaning that he saw as lacking in rigor and insight. One of these was Polish philosopher Alfred Korzybski's General semantics, which was espoused in the US by Stuart Chase. Chase admired Whorf's work and frequently sought out a reluctant Whorf, who considered Chase to be "utterly incompetent by training and background to handle such a subject." Ironically, Chase would later write the foreword for Carroll's collection of Whorf's writings. Work on Hopi and descriptive linguistics Sapir also encouraged Whorf to continue his work on the historical and descriptive linguistics of Uto-Aztecan. Whorf published several articles on that topic in this period, some of them with G. L. Trager, who had become his close friend. Whorf took a special interest in the Hopi language and started working with Ernest Naquayouma, a speaker of Hopi from Toreva village living in Manhattan, New York. Whorf credited Naquayouma as the source of most of his information on the Hopi language, although in 1938 he took a short field trip to the village of Mishongnovi, on the Second Mesa of the Hopi Reservation in Arizona. In 1936, Whorf was appointed honorary research fellow in anthropology at Yale, and he was invited by Franz Boas to serve on the committee of the Society of American Linguistics (later Linguistic Society of America). In 1937, Yale awarded him the Sterling Fellowship. He was a lecturer in anthropology from 1937 through 1938, replacing Sapir, who was gravely ill. Whorf gave graduate level lectures on "Problems of American Indian Linguistics". In 1938 with Trager's assistance he elaborated a report on the progress of linguistic research at the department of anthropology at Yale. The report includes some of Whorf's influential contributions to linguistic theory, such as the concept of the allophone and of covert grammatical categories. has argued, that in this report Whorf's linguistic theories exist in a condensed form, and that it was mainly through this report that Whorf exerted influence on the discipline of descriptive linguistics. Final years In late 1938, Whorf's own health declined. After an operation for cancer, he fell into an unproductive period. He was also deeply affected by Sapir's death in early 1939. It was in the writings of his last two years that he laid out the research program of linguistic relativity. His 1939 memorial article for Sapir, "The Relation of Habitual Thought And Behavior to Language", in particular has been taken to be Whorf's definitive statement of the issue, and is his most frequently quoted piece. In his last year Whorf also published three articles in the MIT Technology Review titled "Science and Linguistics", "Linguistics as an Exact Science" and "Language and Logic". He was also invited to contribute an article to a theosophical journal, Theosophist, published in Madras, India, for which he wrote "Language, Mind and Reality". In these final pieces, he offered a critique of Western science in which he suggested that non-European languages often referred to physical phenomena in ways that more directly reflected aspects of reality than many European languages, and that science ought to pay attention to the effects of linguistic categorization in its efforts to describe the physical world. He particularly criticized the Indo-European languages for promoting a mistaken essentialist world view, which had been disproved by advances in the sciences, whereas he suggested that other languages dedicated more attention to processes and dynamics rather than stable essences. Whorf argued that paying attention to how other physical phenomena are described in the study of linguistics could make valuable contributions to science by pointing out the ways in which certain assumptions about reality are implicit in the structure of language itself, and how language guides the attention of speakers towards certain phenomena in the world which risk becoming overemphasized while leaving other phenomena at risk of being overlooked. Posthumous reception and legacy At Whorf's death, his friend G. L. Trager was appointed as curator of his unpublished manuscripts. Some of them were published in the years after his death by another of Whorf's friends, Harry Hoijer. In the decade following, Trager and particularly Hoijer did much to popularize Whorf's ideas about linguistic relativity, and it was Hoijer who coined the term "Sapir–Whorf hypothesis" at a 1954 conference. Trager then published an article titled "The systematization of the Whorf hypothesis", which contributed to the idea that Whorf had proposed a hypothesis that should be the basis for a program of empirical research. Hoijer also published studies of Indigenous languages and cultures of the American South West in which Whorf found correspondences between cultural patterns and linguistic ones. The term, even though technically a misnomer, went on to become the most widely known label for Whorf's ideas. According to John A. Lucy, "Whorf's work in linguistics was and still is recognized as being of superb professional quality by linguists". Universalism and anti-Whorfianism Whorf's work began to fall out of favor less than a decade after his death, and he was subjected to severe criticism from scholars of language, culture and psychology. In 1953 and 1954, psychologists Roger Brown and Eric Lenneberg criticized Whorf for his reliance on anecdotal evidence, formulating a hypothesis to scientifically test his ideas, which they limited to an examination of a causal relation between grammatical or lexical structure and cognition or perception. Whorf himself did not advocate a straight causality between language and thought; instead he wrote that "Language and culture had grown up together"; that both were mutually shaped by the other. Hence, has argued that because the aim of the formulation of the Sapir–Whorf hypothesis was to test simple causation, it failed to test Whorf's ideas from the outset. Focusing on color terminology, with easily discernible differences between perception and vocabulary, Brown and Lenneberg published in 1954 a study of Zuni color terms that slightly support a weak effect of semantic categorization of color terms on color perception. In doing so they began a line of empirical studies that investigated the principle of linguistic relativity. Empirical testing of the Whorfian hypothesis declined in the 1960s to 1980s as Noam Chomsky began to redefine linguistics and much of psychology in formal universalist terms. Several studies from that period refuted Whorf's hypothesis, demonstrating that linguistic diversity is a surface veneer that masks underlying universal cognitive principles. Many studies were highly critical and disparaging in their language, ridiculing Whorf's analyses and examples or his lack of an academic degree. Throughout the 1980s, most mentions of Whorf or of the Sapir–Whorf hypotheses continued to be disparaging, and led to a widespread view that Whorf's ideas had been proven wrong. Because Whorf was treated so severely in the scholarship during those decades, he has been described as "one of the prime whipping boys of introductory texts to linguistics". With the advent of cognitive linguistics and psycholinguistics in the late 1980s, some linguists sought to rehabilitate Whorf's reputation, as scholarship began to question whether earlier critiques of Whorf were justified. By the 1960s, analytical philosophers also became aware of the Sapir–Whorf hypothesis, and philosophers such as Max Black and Donald Davidson published scathing critiques of Whorf's strong relativist viewpoints. Black characterized Whorf's ideas about metaphysics as demonstrating "amateurish crudity". According to Black and Davidson, Whorf's viewpoint and the concept of linguistic relativity meant that translation between languages with different conceptual schemes would be impossible. Recent assessments such as those by Leavitt and Lee, however, consider Black and Davidson's interpretation to be based on an inaccurate characterization of Whorf's viewpoint, and even rather absurd given the time he spent trying to translate between different conceptual schemes. In their view, the critiques are based on a lack of familiarity with Whorf's writings; according to these recent Whorf scholars a more accurate description of his viewpoint is that he thought translation to be possible, but only through careful attention to the subtle differences between conceptual schemes. Eric Lenneberg, Noam Chomsky, and Steven Pinker have also criticized Whorf for failing to be sufficiently clear in his formulation of how language influences thought, and for failing to provide real evidence to support his assumptions. Generally Whorf's arguments took the form of examples that were anecdotal or speculative, and functioned as attempts to show how "exotic" grammatical traits were connected to what were considered equally exotic worlds of thought. Even Whorf's defenders admitted that his writing style was often convoluted and couched in neologisms – attributed to his awareness of language use, and his reluctance to use terminology that might have pre-existing connotations. argues that Whorf was mesmerized by the foreignness of indigenous languages, and exaggerated and idealized them. According to Lakoff, Whorf's tendency to exoticize data must be judged in the historical context: Whorf and the other Boasians wrote at a time in which racism and jingoism were predominant, and when it was unthinkable to many that "savages" had redeeming qualities, or that their languages were comparable in complexity to those of Europe. For this alone Lakoff argues, Whorf can be considered to be "Not just a pioneer in linguistics, but a pioneer as a human being". Today many followers of universalist schools of thought continue to oppose the idea of linguistic relativity, seeing it as unsound or even ridiculous. For example, Steven Pinker argues in his book The Language Instinct that thought exists prior to language and independently of it, a view also espoused by philosophers of language such as Jerry Fodor, John Locke and Plato. In this interpretation, language is inconsequential to human thought because humans do not think in "natural" language, i.e. any language used for communication. Rather, we think in a meta-language that precedes natural language, which Pinker following Fodor calls "mentalese." Pinker attacks what he calls "Whorf's radical position", declaring, "the more you examine Whorf's arguments, the less sense they make." Scholars of a more "relativist" bent such as John A. Lucy and Stephen C. Levinson have criticized Pinker for misrepresenting Whorf's views and arguing against strawmen. Resurgence of Whorfianism Linguistic relativity studies have experienced a resurgence since the 1990s, and a series of favorable experimental results have brought Whorfianism back into favor, especially in cultural psychology and linguistic anthropology. The first study directing positive attention towards Whorf's relativist position was George Lakoff's "Women, Fire and Dangerous Things", in which he argued that Whorf had been on the right track in his focus on differences in grammatical and lexical categories as a source of differences in conceptualization. In 1992 psychologist John A. Lucy published two books on the topic, one analyzing the intellectual genealogy of the hypothesis, arguing that previous studies had failed to appreciate the subtleties of Whorf's thinking; they had been unable to formulate a research agenda that would actually test Whorf's claims. Lucy proposed a new research design so that the hypothesis of linguistic relativity could be tested empirically, and to avoid the pitfalls of earlier studies which Lucy claimed had tended to presuppose the universality of the categories they were studying. His second book was an empirical study of the relation between grammatical categories and cognition in the Yucatec Maya language of Mexico. In 1996 Penny Lee's reappraisal of Whorf's writings was published, reinstating Whorf as a serious and capable thinker. Lee argued that previous explorations of the Sapir–Whorf hypothesis had largely ignored Whorf's actual writings, and consequently asked questions very unlike those Whorf had asked. Also in that year a volume, "Rethinking Linguistic Relativity" edited by John J. Gumperz and Stephen C. Levinson gathered a range of researchers working in psycholinguistics, sociolinguistics and linguistic anthropology to bring renewed attention to the issue of how Whorf's theories could be updated, and a subsequent review of the new direction of the linguistic relativity paradigm cemented the development. Since then considerable empirical research into linguistic relativity has been carried out, especially at the Max Planck Institute for Psycholinguistics with scholarship motivating two edited volumes of linguistic relativity studies, and in American Institutions by scholars such as Lera Boroditsky and Dedre Gentner. In turn universalist scholars frequently dismiss as "dull" or "boring", positive findings of influence of linguistic categories on thought or behavior, which are often subtle rather than spectacular, suggesting that Whorf's excitement about linguistic relativity had promised more spectacular findings than it was able to provide. Whorf's views have been compared to those of philosophers such as Friedrich Nietzsche and the late Ludwig Wittgenstein, both of whom considered language to have important bearing on thought and reasoning. His hypotheses have also been compared to the views of psychologists such as Lev Vygotsky, whose social constructivism considers the cognitive development of children to be mediated by the social use of language. Vygotsky shared Whorf's interest in gestalt psychology, and he also read Sapir's works. Others have seen similarities between Whorf's work and the ideas of literary theorist Mikhail Bakhtin, who read Whorf and whose approach to textual meaning was similarly holistic and relativistic. Whorf's ideas have also been interpreted as a radical critique of positivist science. Work Linguistic relativity Whorf is best known as the main proponent of what he called the principle of linguistic relativity, but which is often known as "the Sapir–Whorf hypothesis", named for him and Edward Sapir. Whorf never stated the principle in the form of a hypothesis, and the idea that linguistic categories influence perception and cognition was shared by many other scholars before him. But because Whorf, in his articles, gave specific examples of how he saw the grammatical categories of specific languages related to conceptual and behavioral patterns, he pointed towards an empirical research program that has been taken up by subsequent scholars, and which is often called "Sapir–Whorf studies". Sources of influence on Whorf's thinking Whorf and Sapir both drew explicitly on Albert Einstein's principle of general relativity; hence linguistic relativity refers to the concept of grammatical and semantic categories of a specific language providing a frame of reference as a medium through which observations are made. Following an original observation by Boas, Sapir demonstrated that speakers of a given language perceive sounds that are acoustically different as the same, if the sound comes from the underlying phoneme and does not contribute to changes in semantic meaning. Furthermore, speakers of languages are attentive to sounds, particularly if the same two sounds come from different phonemes. Such differentiation is an example of how various observational frames of reference leads to different patterns of attention and perception. Whorf was also influenced by gestalt psychology, believing that languages require their speakers to describe the same events as different gestalt constructions, which he called "isolates from experience". An example is how the action of cleaning a gun is different in English and Shawnee: English focuses on the instrumental relation between two objects and the purpose of the action (removing dirt); whereas the Shawnee language focuses on the movement—using an arm to create a dry space in a hole. The event described is the same, but the attention in terms of figure and ground are different. Degree of influence of language on thought If read superficially, some of Whorf's statements lend themselves to the interpretation that he supported linguistic determinism. For example, in an often-quoted passage Whorf writes: The statements about the obligatory nature of the terms of language have been taken to suggest that Whorf meant that language completely determined the scope of possible conceptualizations. However neo-Whorfians argue that here Whorf is writing about the terms in which we speak of the world, not the terms in which we think of it. Whorf noted that to communicate thoughts and experiences with members of a speech community speakers must use the linguistic categories of their shared language, which requires moulding experiences into the shape of language to speak them—a process called "thinking for speaking". This interpretation is supported by Whorf's subsequent statement that "No individual is free to describe nature with absolute impartiality, but is constrained by certain modes of interpretation even when he thinks himself most free". Similarly the statement that observers are led to different pictures of the universe has been understood as an argument that different conceptualizations are incommensurable making translation between different conceptual and linguistic systems impossible. Neo-Whorfians argue this to be a misreading since throughout his work one of his main points was that such systems could be "calibrated" and thereby be made commensurable, but only when we become aware of the differences in conceptual schemes through linguistic analysis. Hopi time Whorf's study of Hopi time has been the most widely discussed and criticized example of linguistic relativity. In his analysis he argues that there is a relation between how the Hopi people conceptualize time, how they speak of temporal relations, and the grammar of the Hopi language. Whorf's most elaborate argument for the existence of linguistic relativity was based on what he saw as a fundamental difference in the understanding of time as a conceptual category among the Hopi. He argued that the Hopi language, in contrast to English and other SAE languages, does not treat the flow of time as a sequence of distinct countable instances, like "three days" or "five years", but rather as a single process. Because of this difference, the language lacks nouns that refer to units of time. He proposed that the Hopi view of time was fundamental in all aspects of their culture and furthermore explained certain patterns of behavior. In his 1939 memorial essay to Sapir he wrote that "... the Hopi language is seen to contain no words, grammatical forms, construction or expressions that refer directly to what we call 'time', or to past, present, or future..." Linguist Ekkehart Malotki challenged Whorf's analyses of Hopi temporal expressions and concepts with numerous examples how the Hopi language refers to time. Malotki argues that in the Hopi language the system of tenses consists of future and non-future and that the single difference between the three-tense system of European languages and the Hopi system, is that the latter combines past and present to form a single category. Malotki's critique was widely cited as the final piece of evidence in refuting Whorf's ideas and his concept of linguistic relativity while other scholars defended the analysis of Hopi, arguing that Whorf's claim was not that Hopi lacked words or categories to describe temporality, but that the Hopi concept of time is altogether different from that of English speakers. Whorf described the Hopi categories of tense, noting that time is not divided into past, present and future, as is common in European languages, but rather a single tense refers to both present and past while another refers to events that have not yet happened and may or may not happen in the future. He also described a large array of stems that he called "tensors" which describes aspects of temporality, but without referring to countable units of time as in English and most European languages. Contributions to linguistic theory Whorf's distinction between "overt" (phenotypical) and "covert" (cryptotypical) grammatical categories has become widely influential in linguistics and anthropology. British linguist Michael Halliday wrote about Whorf's notion of the "cryptotype", and the conception of "how grammar models reality", that it would "eventually turn out to be among the major contributions of twentieth century linguistics". Furthermore, Whorf introduced the concept of the allophone, a word that describes positional phonetic variants of a single superordinate phoneme; in doing so he placed a cornerstone in consolidating early phoneme theory. The term was popularized by G. L. Trager and Bernard Bloch in a 1941 paper on English phonology and went on to become part of standard usage within the American structuralist tradition. Whorf considered allophones to be another example of linguistic relativity. The principle of allophony describes how acoustically different sounds can be treated as reflections of a single phoneme in a language. This sometimes makes the different sound appear similar to native speakers of the language, even to the point that they are unable to distinguish them auditorily without special training. Whorf wrote that: "[allophones] are also relativistic. Objectively, acoustically, and physiologically the allophones of [a] phoneme may be extremely unlike, hence the impossibility of determining what is what. You always have to keep the observer in the picture. What linguistic pattern makes like is like, and what it makes unlike is unlike".(Whorf, 1940) Central to Whorf's inquiries was the approach later described as metalinguistics by G. L. Trager, who in 1950 published four of Whorf's essays as "Four articles on Metalinguistics". Whorf was crucially interested in the ways in which speakers come to be aware of the language that they use, and become able to describe and analyze language using language itself to do so. Whorf saw that the ability to arrive at progressively more accurate descriptions of the world hinged partly on the ability to construct a metalanguage to describe how language affects experience, and thus to have the ability to calibrate different conceptual schemes. Whorf's endeavors have since been taken up in the development of the study of metalinguistics and metalinguistic awareness, first by Michael Silverstein who published a radical and influential rereading of Whorf in 1979 and subsequently in the field of linguistic anthropology. Studies of Uto-Aztecan languages Whorf conducted important work on the Uto-Aztecan languages, which Sapir had conclusively demonstrated as a valid language family in 1915. Working first on Nahuatl, Tepecano, Tohono O'odham he established familiarity with the language group before he met Sapir in 1928. During Whorf's time at Yale he published several articles on Uto-Aztecan linguistics, such as "Notes on the Tübatulabal language". In 1935 he published "The Comparative Linguistics of Uto-Aztecan", and a review of Kroeber's survey of Uto-Aztecan linguistics. Whorf's work served to further cement the foundations of the comparative Uto-Aztecan studies. The first Native American language Whorf studied was the Uto-Aztecan language Nahuatl which he studied first from colonial grammars and documents, and later became the subject of his first field work experience in 1930. Based on his studies of Classical Nahuatl Whorf argued that Nahuatl was an oligosynthetic language, a typological category that he invented. In Mexico working with native speakers, he studied the dialects of Milpa Alta and Tepoztlán. His grammar sketch of the Milpa Alta dialect of Nahuatl was not published during his lifetime, but it was published posthumously by Harry Hoijer and became quite influential and used as the basic description of "Modern Nahuatl" by many scholars. The description of the dialect is quite condensed and in some places difficult to understand because of Whorf's propensity of inventing his own unique terminology for grammatical concepts, but the work has generally been considered to be technically advanced. He also produced an analysis of the prosody of these dialects which he related to the history of the glottal stop and vowel length in Nahuan languages. This work was prepared for publication by Lyle Campbell and Frances Karttunen in 1993, who also considered it a valuable description of the two endangered dialects, and the only one of its kind to include detailed phonetic analysis of supra-segmental phenomena. In Uto-Aztecan linguistics one of Whorf's achievements was to determine the reason the Nahuatl language has the phoneme , not found in the other languages of the family. The existence of in Nahuatl had puzzled previous linguists and caused Sapir to reconstruct a phoneme for proto-Uto-Aztecan based only on evidence from Aztecan. In a 1937 paper published in the journal American Anthropologist, Whorf argued that the phoneme resulted from some of the Nahuan or Aztecan languages having undergone a sound change from the original * to in the position before *. This sound law is known as "Whorf's law", considered valid although a more detailed understanding of the precise conditions under which it took place has since been developed. Also in 1937, Whorf and his friend G. L. Trager, published a paper in which they elaborated on the Azteco-Tanoan language family, proposed originally by Sapir as a family comprising the Uto-Aztecan and the Kiowa-Tanoan languages—(the Tewa and Kiowa languages). Maya epigraphy In a series of published and unpublished studies in the 1930s, Whorf argued that Mayan writing was to some extent phonetic. While his work on deciphering the Maya script gained some support from Alfred Tozzer at Harvard, the main authority on Ancient Maya culture, J. E. S. Thompson, strongly rejected Whorf's ideas, saying that Mayan writing lacked a phonetic component and is therefore impossible to decipher based on a linguistic analysis. Whorf argued that it was exactly the reluctance to apply linguistic analysis of Maya languages that had held the decipherment back. Whorf sought for cues to phonetic values within the elements of the specific signs, and never realized that the system was logo-syllabic. Although Whorf's approach to understanding the Maya script is now known to have been misguided, his central claim that the script was phonetic and should be deciphered as such was vindicated by Yuri Knorozov's syllabic decipherment of Mayan writing in the 1950s.

Bill Clinton

William Jefferson Clinton (né Blythe III; born August 19, 1946) is an American politician who served as the 42nd president of the United States from 1993 to 2001. A member of the Democratic Party, he previously served as governor of Arkansas from 1979 to 1981 and again from 1983 to 1992. Clinton, whose policies reflected a centrist "Third Way" political philosophy, became known as a New Democrat. Clinton was born and raised in Arkansas. He graduated from Georgetown University and later from Yale Law School, where he met his future wife, Hillary Rodham. After graduating from law school, Clinton returned to Arkansas and won election as state attorney general, followed by two non-consecutive tenures as Arkansas governor. As governor, he overhauled the state's education system and served as chairman of the National Governors Association. Clinton was elected president in the 1992 election, defeating incumbent Republican president George H. W. Bush and independent businessman Ross Perot. He became the first president to be born in the Baby Boomer generation. Clinton presided over the longest period of peacetime economic expansion in American history. He signed into law the North American Free Trade Agreement and the Violent Crime Control and Law Enforcement Act, but failed to pass his plan for national health care reform. The Republican Party won unified control of Congress for the first time in 40 years in the 1994 elections, but Clinton was still comfortably re-elected president in 1996 against both Republican Bob Dole and Perot—now the Reform Party nominee. Starting in the mid-1990s, he began an ideological evolution as he became much more conservative in his domestic policy, advocating for and signing the Personal Responsibility and Work Opportunity Act, the State Children's Health Insurance Program and financial deregulation measures. He appointed Ruth Bader Ginsburg and Stephen Breyer to the U.S. Supreme Court. During the last three years of Clinton's presidency, the Congressional Budget Office reported a budget surplus—the first such surplus since 1969. In foreign policy, Clinton ordered U.S. military intervention in the Bosnian and Kosovo wars, eventually signing the Dayton Peace agreement. He also called for the expansion of NATO in Eastern Europe and many former Warsaw Pact members joined NATO during his presidency. Clinton's foreign policy in the Middle East saw him sign the Iraq Liberation Act which gave aid to groups against Saddam Hussein. He also participated in the Oslo I Accord and Camp David Summit to advance the Israeli–Palestinian peace process, and assisted the Northern Ireland peace process. Clinton's second term was dominated by the Clinton–Lewinsky scandal, which began in 1995, when he had a sexual relationship with 22-year-old White House intern Monica Lewinsky. In January 1998, news of the affair made tabloid headlines. This scandal escalated throughout the year, culminating in December when Clinton was impeached by the House of Representatives. The two impeachment articles that the House passed were centered around him using the powers of the presidency to obstruct the investigation and lying under oath. In 1999, Clinton's impeachment trial began in the Senate, where he was acquitted on both charges. Clinton left office in 2001 with the joint-highest approval rating of any U.S. president. His presidency ranks among the middle to upper tier in historical rankings of U.S. presidents. However, his personal conduct and allegations of sexual assault have made him the subject of substantial scrutiny. Since leaving office, Clinton has been involved in public speaking and humanitarian work. He created the Clinton Foundation to address international causes such as the prevention of HIV/AIDS and global warming. In 2009, he was named the United Nations special envoy to Haiti. After the 2010 Haiti earthquake, Clinton founded the Clinton Bush Haiti Fund. He has remained active in Democratic Party politics, campaigning for his wife's 2008 and 2016 presidential campaigns. Early life and career Clinton was born William Jefferson Blythe III on August 19, 1946, at Julia Chester Hospital in Hope, Arkansas. He is the son of William Jefferson Blythe Jr., a traveling salesman who died in an automobile accident three months before his birth, and Virginia Dell Cassidy (later Virginia Kelley). His parents had married on September 4, 1943, but this union later proved to be bigamous, as Blythe was still married to his fourth wife. Virginia traveled to New Orleans to study nursing soon after Bill was born, leaving him in Hope with her parents Eldridge and Edith Cassidy, who owned and ran a small grocery store. At a time when the southern United States was racially segregated, Clinton's grandparents sold goods on credit to people of all races. In 1950, Bill's mother returned from nursing school and married Roger Clinton Sr., who co-owned an automobile dealership in Hot Springs, Arkansas, with his brother and Earl T. Ricks. The family moved to Hot Springs in 1950. Although he immediately assumed use of his stepfather's surname, it was not until Clinton turned 15 that he formally adopted the surname Clinton as a gesture toward him. Clinton has described his stepfather as a gambler and an alcoholic who regularly abused his mother and half-brother, Roger Clinton Jr. The physical abuse only ceased after a then-14-year-old Bill challenged his stepfather to "stand and face" him, though the verbal/emotional abuse continued. Bill would eventually forgive Roger Sr. for his abusive actions near the latter's death. In Hot Springs, Clinton attended St. John's Catholic Elementary School, Ramble Elementary School, and the segregated Hot Springs High School, where he was an active student leader, avid reader, and musician. Clinton was in the chorus and played the tenor saxophone, winning first chair in the state band's saxophone section. In 1961, Clinton became a member of the Hot Springs Chapter of the Order of DeMolay, a youth group affiliated with Freemasonry, but he never became a Freemason. He briefly considered dedicating his life to music, but as he noted in his autobiography My Life: Clinton began an interest in law at Hot Springs High, when he took up the challenge to argue the defense of the ancient Roman senator Catiline in a mock trial in his Latin class. After a vigorous defense that made use of his "budding rhetorical and political skills", he told the Latin teacher Elizabeth Buck it "made him realize that someday he would study law". Clinton has identified two influential moments in his life, both occurring in 1963, that contributed to his decision to become a public figure. One was his visit as a Boys Nation senator to the White House to meet President John F. Kennedy. The other was watching Martin Luther King Jr.'s 1963 "I Have a Dream" speech on TV, which impressed him so much that he later memorized it. College and law school years Georgetown University With the aid of scholarships, Clinton attended the School of Foreign Service at Georgetown University in Washington, D.C., receiving a Bachelor of Science in foreign service degree in 1968. Georgetown was the only school where Clinton applied. In 1964 and 1965, Clinton won elections for class president. From 1964 to 1967, he was an intern and then a clerk in the office of Arkansas Senator J. William Fulbright. While in college, he became a brother of service fraternity Alpha Phi Omega and was elected to Phi Beta Kappa. He is a member of Kappa Kappa Psi honorary band fraternity. Oxford Upon graduating from Georgetown in 1968, Clinton won a Rhodes Scholarship to University College, Oxford, where he initially read for a B.Phil. in philosophy, politics, and economics but transferred to a B.Litt. in politics and, ultimately, a B.Phil. in politics. Clinton did not expect to return for the second year because of the draft and so he switched programs; this type of activity was common among other Rhodes Scholars from his cohort. He had received an offer to study at Yale Law School, and so he left early to return to the United States and did not receive a degree from Oxford. During his time at Oxford, Clinton befriended fellow American Rhodes Scholar Frank Aller. In 1969, Aller received a draft letter that mandated deployment to the Vietnam War. Aller's 1971 suicide had an influential impact on Clinton. British writer and feminist Sara Maitland said of Clinton, "I remember Bill and Frank Aller taking me to a pub in Walton Street in the summer term of 1969 and talking to me about the Vietnam War. I knew nothing about it, and when Frank began to describe the napalming of civilians I began to cry. Bill said that feeling bad wasn't good enough. That was the first time I encountered the idea that liberal sensitivities weren't enough and you had to do something about such things". Clinton was a member of the Oxford University Basketball Club and also played for Oxford University's rugby union team. While Clinton was president in 1994, he received an honorary degree and a fellowship from the University of Oxford, specifically for being "a doughty and tireless champion of the cause of world peace", having "a powerful collaborator in his wife", and for winning "general applause for his achievement of resolving the gridlock that prevented an agreed budget". Vietnam War opposition and draft controversy During the Vietnam War, Clinton received educational draft deferments while he was in England in 1968 and 1969. While at Oxford, he participated in Vietnam War protests and organized a Moratorium to End the War in Vietnam event in October 1969. He was planning to attend law school in the U.S. and knew he might lose his deferment. Clinton tried unsuccessfully to obtain positions in the National Guard and the Air Force officer candidate school, and he then made arrangements to join the Reserve Officers' Training Corps (ROTC) program at the University of Arkansas. He subsequently decided not to join the ROTC, saying in a letter to the officer in charge of the program that he opposed the war, but did not think it was honorable to use ROTC, National Guard, or Reserve service to avoid serving in Vietnam. He further stated that because he opposed the war, he would not volunteer to serve in uniform, but would subject himself to the draft, and would serve if selected only as a way "to maintain my political viability within the system". Clinton registered for the draft and received a high number (311), meaning that those whose birthdays had been drawn as numbers1 to 310 would be drafted before him, making it unlikely he would be called up. (In fact, the highest number drafted was 195.) Colonel Eugene Holmes, the Army officer who had been involved with Clinton's ROTC application, suspected that Clinton attempted to manipulate the situation to avoid the draft and avoid serving in uniform. He issued a notarized statement during the 1992 presidential campaign: During the 1992 campaign, it was revealed that Clinton's uncle had attempted to secure him a position in the Navy Reserve, which would have prevented him from being deployed to Vietnam. This effort was unsuccessful and Clinton said in 1992 that he had been unaware of it until then. Although legal, Clinton's actions with respect to the draft and deciding whether to serve in the military were criticized during his first presidential campaign by conservatives and some Vietnam veterans, some of whom charged that he had used Fulbright's influence to avoid military service. Clinton's 1992 campaign manager, James Carville, successfully argued that Clinton's letter in which he declined to join the ROTC should be made public, insisting that voters, many of whom had also opposed the Vietnam War, would understand and appreciate his position. Law school After Oxford, Clinton attended Yale Law School and earned a Juris Doctor (J.D.) degree in 1973. In 1971, he met his future wife, Hillary Rodham, in the Yale Law Library; she was a class year ahead of him. They began dating and were soon inseparable. After only about a month, Clinton postponed his summer plans to be a coordinator for the George McGovern campaign for the 1972 United States presidential election in order to move in with her in California. The couple continued living together in New Haven when they returned to law school. Clinton eventually moved to Texas with Rodham in 1972 to take a job leading McGovern's effort there. He spent considerable time in Dallas, at the campaign's local headquarters on Lemmon Avenue, where he had an office. Clinton worked with future two-term mayor of Dallas Ron Kirk, future governor of Texas Ann Richards, and then unknown television director and filmmaker Steven Spielberg. Failed congressional campaign and tenure as Attorney General of Arkansas After graduating from Yale Law School, Clinton returned to Arkansas and became a law professor at the University of Arkansas. In 1974, he ran for the House of Representatives. Running in the conservative 3rd district against incumbent Republican John Paul Hammerschmidt, Clinton's campaign was bolstered by the anti-Republican and anti-incumbent mood resulting from the Watergate scandal. Hammerschmidt, who had received 77 percent of the vote in 1972, defeated Clinton by only a 52 percent to 48 percent margin. In 1976, Clinton ran for Arkansas attorney general. Defeating the secretary of state and the deputy attorney general in the Democratic primary, Clinton was elected with no opposition at all in the general election, as no Republican had run for the office. Governor of Arkansas (1979–1981, 1983–1992) In 1978, Clinton entered the Arkansas gubernatorial primary. At just 31 years old, he was one of the youngest gubernatorial candidates in the state's history. Clinton was elected governor of Arkansas in 1978, having defeated the Republican candidate Lynn Lowe, a farmer from Texarkana. Clinton was only 32 years old when he took office, the youngest governor in the country at the time and the second youngest governor in the history of Arkansas. Due to his youthful appearance, Clinton was often called the "Boy Governor". He worked on educational reform and directed the maintenance of Arkansas's roads, with wife Hillary leading a successful committee on urban health care reform. However, his term included an unpopular motor vehicle tax and citizens' anger over the escape of Cuban refugees (from the Mariel boatlift) detained in Fort Chaffee in 1980. Monroe Schwarzlose, of Kingsland in Cleveland County, polled 31 percent of the vote against Clinton in the Democratic gubernatorial primary of 1980. Some suggested Schwarzlose's unexpected voter turnout foreshadowed Clinton's defeat by Republican challenger Frank D. White in the general election that year. As Clinton once joked, he was the youngest ex-governor in the nation's history. Clinton joined friend Bruce Lindsey's Little Rock law firm of Wright, Lindsey and Jennings. In 1982, he was elected governor a second time and kept the office for ten years. Effective with the 1986 election, Arkansas had changed its gubernatorial term of office from two to four years. During his term, he helped transform Arkansas's economy and improved the state's educational system. For senior citizens, he removed the sales tax from medications and increased the home property-tax exemption. He became a leading figure among the New Democrats, a group of Democrats who advocated welfare reform, smaller government, and other policies not supported by liberals. Formally organized as the Democratic Leadership Council (DLC), the New Democrats argued that in light of President Ronald Reagan's landslide victory in 1984, the Democratic Party needed to adopt a more centrist political stance in order to succeed at the national level. Clinton delivered the Democratic response to Reagan's 1985 State of the Union Address and served as chair of the National Governors Association from 1986 to 1987, bringing him to an audience beyond Arkansas. In the early 1980s, Clinton made reform of the Arkansas education system a top priority of his gubernatorial administration. The Arkansas Education Standards Committee was chaired by Clinton's wife Hillary, who was also an attorney as well as the chair of the Legal Services Corporation. The committee transformed Arkansas's education system. Proposed reforms included more spending for schools (supported by a sales-tax increase), better opportunities for gifted children, vocational education, higher teachers' salaries, more course variety, and compulsory teacher competency exams. The reforms passed in September 1983 after Clinton called a special legislative session—the longest in Arkansas history. Many have considered this the greatest achievement of the Clinton governorship. He defeated four Republican candidates for governor: Lowe (1978), White (1982 and 1986), Jonesboro businessmen Woody Freeman (1984), and Sheffield Nelson of Little Rock (1990). Also in the 1980s, the Clintons' personal and business affairs included transactions that became the basis of the Whitewater controversy investigation, which later dogged his presidential administration. After extensive investigation over several years, no indictments were made against the Clintons related to the years in Arkansas. According to some sources, Clinton was a death penalty opponent in his early years, but he eventually switched positions. However he might have felt previously, by 1992, Clinton was insisting that Democrats "should no longer feel guilty about protecting the innocent". During Clinton's final term as governor, Arkansas performed its first executions since 1964 (the death penalty had been reinstated in 1976). As Governor, he oversaw the first four executions carried out by the state of Arkansas since the death penalty was reinstated there in 1976: one by electric chair and three by lethal injection. To draw attention to his stance on capital punishment, Clinton flew home to Arkansas mid-campaign in 1992, in order to affirm in person that the controversial execution of Ricky Ray Rector, would go forward as scheduled. 1988 Democratic presidential primaries In 1987, the media speculated that Clinton would enter the presidential race after incumbent New York governor Mario Cuomo declined to run and Democratic front-runner Gary Hart withdrew owing to revelations of multiple marital infidelities. Clinton decided to remain as Arkansas governor (following consideration for the potential candidacy of Hillary for governor, initially favored—but ultimately vetoed—by the First Lady). For the nomination, Clinton endorsed Massachusetts governor Michael Dukakis. He gave the nationally televised opening night address at the 1988 Democratic National Convention, but his speech, which was 33 minutes long and twice the length it was expected to be, was criticized for being too long and poorly delivered. Clinton presented himself both as a moderate and as a member of the New Democrat wing of the Democratic Party, and he headed the moderate Democratic Leadership Council in 1990 and 1991. 1992 United States presidential election In the first primary contest, the Iowa Caucus, Clinton finished a distant third to Iowa senator Tom Harkin. During the campaign for the New Hampshire primary, reports surfaced that Clinton had engaged in an extramarital affair with Gennifer Flowers. Clinton fell far behind former Massachusetts senator Paul Tsongas in the New Hampshire polls. Following Super Bowl XXVI, Clinton and his wife Hillary went on 60 Minutes to rebuff the charges. Their television appearance was a calculated risk, but Clinton regained several delegates. He finished second to Tsongas in the New Hampshire primary, but after trailing badly in the polls and coming within single digits of winning, the media viewed it as a victory. News outlets labeled him "The Comeback Kid" for earning a firm second-place finish. Winning the big prizes of Florida and Texas and many of the Southern primaries on Super Tuesday gave Clinton a sizable delegate lead. However, former California governor Jerry Brown was scoring victories and Clinton had yet to win a significant contest outside his native South. With no major Southern state remaining, Clinton targeted New York, which had many delegates. He scored a resounding victory in New York City, shedding his image as a regional candidate. Having been transformed into the consensus candidate, he secured the Democratic Party nomination, finishing with a victory in Jerry Brown's home state of California. During the campaign, questions of conflict of interest regarding state business and the politically powerful Rose Law Firm, at which Hillary Rodham Clinton was a partner, arose. Clinton argued the questions were moot because all transactions with the state had been deducted before determining Hillary's firm pay. Further concern arose when Bill Clinton announced that, with Hillary, voters would be getting two presidents "for the price of one". Clinton was still the governor of Arkansas while campaigning for U.S. president, and he returned to his home state to see that Ricky Ray Rector would be executed. After killing a police officer and a civilian, Rector shot himself in the head, leading to what his lawyers said was a state where he could still talk but did not understand the idea of death. According to both Arkansas state law and federal law, a seriously mentally impaired inmate cannot be executed. The courts disagreed with the allegation of grave mental impairment and allowed the execution. Clinton's return to Arkansas for the execution was framed in an article for The New York Times as a possible political move to counter "soft on crime" accusations. Bush's approval ratings were around 80 percent during the Gulf War, and he was described as unbeatable. When Bush compromised with Democrats to try to lower federal deficits, he reneged on his promise not to raise taxes, which hurt his approval rating. Clinton repeatedly condemned Bush for making a promise he failed to keep. By election time, the economy was souring and Bush saw his approval rating plummet to just slightly over 40 percent. Finally, conservatives were previously united by anti-communism, but with the end of the Cold War, the party lacked a uniting issue. When Pat Buchanan and Pat Robertson addressed Christian themes at the Republican National Convention—with Bush criticizing Democrats for omitting God from their platform—many moderates were alienated. Clinton then pointed to his moderate, "New Democrat" record as governor of Arkansas, though some on the more liberal side of the party remained suspicious. Many Democrats who had supported Ronald Reagan and Bush in previous elections switched their support to Clinton. Clinton and his running mate, Al Gore, toured the country during the final weeks of the campaign, shoring up support and pledging a "new beginning". On March 26, 1992, during a Democratic fund raiser of the presidential campaign, Robert Rafsky confronted then Gov. Bill Clinton of Arkansas and asked what he was going to do about AIDS, to which Clinton replied, "I feel your pain". The televised exchange led to AIDS becoming an issue in the 1992 presidential election. On April 4, then candidate Clinton met with members of ACT UP and other leading AIDS advocates to discuss his AIDS agenda and agreed to make a major AIDS policy speech, to have people with HIV speak to the Democratic Convention, and to sign onto the AIDS United Action five point plan. Clinton won the 1992 presidential election (370 electoral votes) against Republican incumbent George H. W. Bush (168 electoral votes) and billionaire populist Ross Perot (zero electoral votes), who ran as an independent on a platform that focused on domestic issues. Bush's steep decline in public approval was a significant part of Clinton's success. Clinton's victory in the election ended twelve years of Republican rule of the White House and twenty of the previous twenty-four years. The election gave Democrats full control of the United States Congress, the first time one party controlled both the executive and legislative branches since Democrats held the 96th United States Congress during the presidency of Jimmy Carter. According to Seymour Martin Lipset, the 1992 election had several unique characteristics. Voters felt that economic conditions were worse than they actually were, which harmed Bush. A rare event was the presence of a strong third-party candidate. Liberals launched a backlash against 12 years of a conservative White House. The chief factor was Clinton's uniting his party, and winning over a number of heterogeneous groups. Presidency (1993–2001) Clinton's "third way" of moderate liberalism built up the nation's fiscal health and put the nation on a firm footing abroad amid globalization and the development of anti-American terrorist organizations. During his presidency, Clinton advocated for a wide variety of legislation and programs, most of which were enacted into law or implemented by the executive branch. His policies, particularly the North American Free Trade Agreement and welfare reform, have been attributed to a centrist Third Way philosophy of governance. His policy of fiscal conservatism helped to reduce deficits on budgetary matters. Clinton presided over the longest period of peacetime economic expansion in American history. The Congressional Budget Office reported budget surpluses of $69 billion in 1998, $126 billion in 1999, and $236 billion in 2000, during the last three years of Clinton's presidency. Over the years of the recorded surplus, the gross national debt rose each year. At the end of the fiscal year (September 30) for each of the years a surplus was recorded, The U.S. treasury reported a gross debt of $5.413 trillion in 1997, $5.526 trillion in 1998, $5.656 trillion in 1999, and $5.674 trillion in 2000. Over the same period, the Office of Management and Budget reported an end of year (December 31) gross debt of $5.369 trillion in 1997, $5.478 trillion in 1998, $5.606 in 1999, and $5.629 trillion in 2000. At the end of his presidency, the Clintons moved to 15 Old House Lane in Chappaqua, New York, in order to quell political worries about his wife's residency for election as a U.S. Senator from New York. First term (1993–1997) After his presidential transition, Clinton was inaugurated as the 42nd president of the United States on January 20, 1993. Clinton was physically exhausted at the time, and had an inexperienced staff. His high levels of public support dropped in the first few weeks, as he made a series of mistakes. His first choice for attorney general had not paid her taxes on babysitters and was forced to withdraw. The second appointee also withdrew for the same reason. Clinton had repeatedly promised to encourage gays in the military service, despite what he knew to be the strong opposition of the military leadership. He tried anyway, and was publicly opposed by the top generals, and forced by Congress to a compromise position of "Don't ask, don't tell" whereby gays could serve if and only if they kept it secret. He devised a $16-billion stimulus package primarily to aid inner-city programs desired by liberals, but it was defeated by a Republican filibuster in the Senate. His popularity at the 100 day mark of his term was the lowest of any president at that point. Public opinion did support one liberal program, and Clinton signed the Family and Medical Leave Act of 1993, which required large employers to allow employees to take unpaid leave for pregnancy or a serious medical condition. This action had bipartisan support, and was popular with the public. Two days after taking office, on January 22, 1993—the 20th anniversary of the U.S. Supreme Court decision in Roe v. Wade—Clinton reversed restrictions on domestic and international family planning programs that had been imposed by Reagan and Bush. Clinton said abortion should be kept "safe, legal, and rare"—a slogan that had been suggested by political scientist Samuel L. Popkin and first used by Clinton in December 1991, while campaigning. During the eight years of the Clinton administration, the abortion rate declined by 18 percent. On February 15, 1993, Clinton made his first address to the nation, announcing his plan to raise taxes to close a budget deficit. Two days later, in a nationally televised address to a joint session of Congress, Clinton unveiled his economic plan. The plan focused on reducing the deficit rather than on cutting taxes for the middle class, which had been high on his campaign agenda. Clinton's advisers pressured him to raise taxes, based on the theory that a smaller federal budget deficit would reduce bond interest rates. President Clinton's attorney general Janet Reno authorized the FBI's use of armored vehicles to deploy tear gas into the buildings of the Branch Davidian community near Waco, Texas, in hopes of ending a 51 day siege. During the operation on April 19, 1993, the buildings caught fire and 75 of the residents died, including 24 children. The raid had originally been planned by the Bush administration; Clinton had played no role. In August, Clinton signed the Omnibus Budget Reconciliation Act of 1993, which passed Congress without a Republican vote. It cut taxes for 15million low-income families, made tax cuts available to 90 percent of small businesses, and raised taxes on the wealthiest 1.2 percent of taxpayers. Additionally, it mandated that the budget be balanced over many years through the implementation of spending restraints. On September 22, 1993, Clinton made a major speech to Congress regarding a health care reform plan; the program aimed at achieving universal coverage through a national health care plan. This was one of the most prominent items on Clinton's legislative agenda and resulted from a task force headed by Hillary Clinton. The plan was well received in political circles, but it was eventually doomed by well-organized lobby opposition from conservatives, the American Medical Association, and the health insurance industry. However, Clinton biographer John F. Harris said the program failed because of a lack of coordination within the White House. Despite the Democratic majority in Congress, the effort to create a national health care system ultimately died when compromise legislation by George J. Mitchell failed to gain a majority of support in August 1994. The failure of the bill was the first major legislative defeat of the Clinton administration. On November 30, 1993, Clinton signed into law the Brady Bill, which mandated federal background checks on people who purchase firearms in the United States. The law also imposed a five-day waiting period on purchases, until the NICS system was implemented in 1998. He also expanded the Earned Income Tax Credit, a subsidy for low-income workers. In December of the same year, allegations by Arkansas state troopers Larry Patterson and Roger Perry were first reported by David Brock in The American Spectator. In the affair later known as "Troopergate", the officers alleged that they had arranged sexual liaisons for Clinton back when he was governor of Arkansas. The story mentioned a woman named Paula, a reference to Paula Jones. Brock later apologized to Clinton, saying the article was politically motivated "bad journalism", and that "the troopers were greedy and had slimy motives". That month, Clinton implemented a Department of Defense directive known as "Don't Ask, Don't Tell", which allowed gay men and women to serve in the armed services provided they kept their sexual preferences a secret. The Act forbade the military from inquiring about an individual's sexual orientation. The policy was developed as a compromise after Clinton's proposal to allow gays to serve openly in the military met staunch opposition from prominent Congressional Republicans and Democrats, including senators John McCain (R-AZ) and Sam Nunn (D-GA). According to David Mixner, Clinton's support for the compromise led to a heated dispute with Vice President Al Gore, who felt that "the President should lift the ban ... even though [his executive order] was sure to be overridden by the Congress". Some gay-rights advocates criticized Clinton for not going far enough and accused him of making his campaign promise to get votes and contributions. Their position was that Clinton should have integrated the military by executive order, noting that President Harry S. Truman used executive order to racially desegregate the armed forces. Clinton's defenders argued that an executive order might have prompted the Senate to write the exclusion of gays into law, potentially making it harder to integrate the military in the future. Later in his presidency, in 1999, Clinton criticized the way the policy was implemented, saying he did not think any serious person could say it was not "out of whack". The policy remained controversial, and was finally repealed in 2011, removing open sexual orientation as a reason for dismissal from the armed forces. On January 1, 1994, Clinton signed the North American Free Trade Agreement into law. Throughout his first year in office, Clinton consistently supported ratification of the treaty by the U.S. Senate. Clinton and most of his allies in the Democratic Leadership Committee strongly supported free trade measures; there remained, however, strong disagreement within the party. Opposition came chiefly from anti-trade Republicans, protectionist Democrats and supporters of Ross Perot. The bill passed the house with 234 votes in favor and 200 votes opposed (132 Republicans and 102 Democrats in favor; 156 Democrats, 43 Republicans, and one independent opposed). The treaty was then ratified by the Senate and signed into law by the president. On July 29, 1994, the Clinton administration launched the first official White House website, whitehouse.gov. The site was followed with three more versions, with the final version being launched on July 21, 2000. The White House website was part of a wider movement of the Clinton administration toward web-based communication. According to Robert Longley, "Clinton and Gore were responsible for pressing almost all federal agencies, the U.S. court system and the U.S. military onto the Internet, thus opening up America's government to more of America's citizens than ever before. On July 17, 1996, Clinton issued Executive Order 13011—Federal Information Technology, ordering the heads of all federal agencies to utilize information technology fully to make the information of the agency easily accessible to the public." The Omnibus Crime Bill, which Clinton signed into law in September 1994, made many changes to U.S. crime and law enforcement legislation including the expansion of the death penalty to include crimes not resulting in death, such as running a large-scale drug enterprise. During Clinton's re-election campaign he said, "My 1994 crime bill expanded the death penalty for drug kingpins, murderers of federal law enforcement officers, and nearly 60 additional categories of violent felons." It also included a subsection of assault weapons ban for a ten-year period. After two years of Democratic Party control, the Democrats lost control of Congress to the Republicans in the mid-term elections in 1994, for the first time in forty years. A speech delivered by President Bill Clinton at the December 6, 1995 White House Conference on HIV/AIDS projected that a cure for AIDS and a vaccine to prevent further infection would be developed. The President focused on his administration's accomplishments and efforts related to the epidemic, including an accelerated drug-approval process. He also condemned homophobia and discrimination against people with HIV. Clinton announced three new initiatives: creating a special working group to coordinate AIDS research throughout the federal government; convening public health experts to develop an action plan that integrates HIV prevention with substance abuse prevention; and launching a new effort by the Department of Justice to ensure that health care facilities provide equal access to people with HIV and AIDS. On September 21, 1996, Clinton signed into law the Defense of Marriage Act (DOMA), which defined marriage for federal purposes as the legal union of one man and one woman; the legislation allowed individual states to refuse to recognize gay marriages that were performed in other states. Paul Yandura, speaking for the White House gay and lesbian liaison office, said Clinton's signing DOMA "was a political decision that they made at the time of a re-election". In defense of his actions, Clinton has said that DOMA was intended to "head off an attempt to send a constitutional amendment banning gay marriage to the states", a possibility he described as highly likely in the context of a "very reactionary Congress". Administration spokesman Richard Socarides said, "the alternatives we knew were going to be far worse, and it was time to move on and get the president re-elected." Clinton himself said DOMA was something "which the Republicans put on the ballot to try to get the base vote for Bush up, I think it's obvious that something had to be done to try to keep the Republican Congress from presenting that"; Others were more critical. The veteran gay rights and gay marriage activist Evan Wolfson has called these claims "historic revisionism". Despite this, it has been noted that other than a brief written response to a Reader's Digest that questioned whether he agreed with it, Clinton had made no documented reference to the issue of gay marriage until May 1996. In a July 2, 2011, editorial The New York Times opined, "The Defense of Marriage Act was enacted in 1996 as an election-year wedge issue, signed by President Bill Clinton in one of his worst policy moments." Ultimately, in United States v. Windsor, the U.S. Supreme Court struck down DOMA in June 2013. Despite DOMA, Clinton was the first president to select openly gay persons for administrative positions, and he is generally credited as being the first president to publicly champion gay rights. During his presidency, Clinton issued two substantially controversial executive orders on behalf of gay rights, the first lifting the ban on security clearances for LGBT federal employees and the second outlawing discrimination based on sexual orientation in the federal civilian workforce. Under Clinton's leadership, federal funding for HIV/AIDS research, prevention and treatment more than doubled. Clinton also pushed for passing hate crimes laws for gays and for the private sector Employment Non-Discrimination Act, which, buoyed by his lobbying, failed to pass the Senate by a single vote in 1996. Advocacy for these issues, paired with the politically unpopular nature of the gay rights movement at the time, led to enthusiastic support for Clinton's election and reelection by the Human Rights Campaign. Clinton came out for gay marriage in July 2009 and urged the Supreme Court to overturn DOMA in 2013. He was later honored by GLAAD for his prior pro-gay stances and his reversal on DOMA. The 1996 United States campaign finance controversy was an alleged effort by China to influence the domestic policies of the United States, before and during the Clinton administration, and involved the fundraising practices of the administration itself. Despite the evidence, the Chinese government denied all accusations. As part of a 1996 initiative to curb illegal immigration, Clinton signed the Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA) on September 30, 1996. Appointed by Clinton, the U.S. Commission on Immigration Reform recommended reducing legal immigration from about 800,000 people a year to about 550,000. In November 1996, Clinton narrowly escaped possible assassination in the Philippines, which was a bridge bomb planted by al-Qaeda and was masterminded by Osama bin Laden. During Clinton's presidency, the attempt remained top secret. 1996 presidential campaign In the 1996 presidential election, Clinton was re-elected, receiving 49.2 percent of the popular vote over Republican Bob Dole (40.7 percent of the popular vote) and Reform candidate Ross Perot (8.4 percent of the popular vote). Clinton received 379 of the Electoral College votes, with Dole receiving 159 electoral votes. With his victory, he became the first Democrat to win two consecutive presidential elections since Franklin D. Roosevelt. Second term (1997–2001) In the January 1997, State of the Union address, Clinton proposed a new initiative to provide health coverage to up to five million children. Senators Ted Kennedy—a Democrat—and Orrin Hatch—a Republican—teamed up with Hillary Rodham Clinton and her staff in 1997, and succeeded in passing legislation forming the State Children's Health Insurance Program (SCHIP), the largest (successful) health care reform in the years of the Clinton Presidency. That year, Hillary Clinton shepherded through Congress the Adoption and Safe Families Act and two years later she succeeded in helping pass the Foster Care Independence Act. Bill Clinton negotiated the passage of the Balanced Budget Act of 1997 by the Republican Congress. In October 1997, he announced he was getting hearing aids, due to hearing loss attributed to his age, and his time spent as a musician in his youth. In 1999, he signed into law the Financial Services Modernization Act also known as the Gramm–Leach–Bliley Act, which repealed the part of the Glass–Steagall Act that had prohibited a bank from offering a full range of investment, commercial banking, and insurance services since its enactment in 1933. Investigations In November 1993, David Hale—the source of criminal allegations against Bill Clinton in the Whitewater controversy—alleged that while governor of Arkansas, Clinton pressured Hale to provide an illegal $300,000 loan to Susan McDougal, the Clintons' partner in the Whitewater land deal. A U.S. Securities and Exchange Commission investigation resulted in convictions against the McDougals for their role in the Whitewater project, but the Clintons themselves were never charged, and Clinton maintains his and his wife's innocence in the affair. Investigations Robert B. Fiske and Ken Starr found insufficient to evidence to prosecute the Clintons. The White House FBI files controversy of June 1996 arose concerning improper access by the White House to FBI security-clearance documents. Craig Livingstone, head of the White House Office of Personnel Security, improperly requested, and received from the FBI, background report files without asking permission of the subject individuals; many of these were employees of former Republican administrations. In March 2000, Independent Counsel Robert Ray determined there was no credible evidence of any crime. Ray's report further stated, "there was no substantial and credible evidence that any senior White House official was involved" in seeking the files. On May 19, 1993, Clinton fired seven employees of the White House Travel Office. This caused the White House travel office controversy even though the travel office staff served at the pleasure of the president and could be dismissed without cause. The White House responded to the controversy by claiming that the firings were done in response to financial improprieties that had been revealed by a brief FBI investigation. Critics contended that the firings had been done to allow friends of the Clintons to take over the travel business and the involvement of the FBI was unwarranted. The House Government Reform and Oversight Committee issued a report which accused the Clinton administration of having obstructed their efforts to investigate the affair. Special counsel Robert Fiske said that Hillary Clinton was involved in the firing and gave "factually false" testimony to the GAO, congress, and the independent counsel. However Fiske said there was not enough evidence to prosecute. Impeachment and acquittal After a House inquiry, Clinton was impeached on December 19, 1998, by the House of Representatives. The House voted 228–206 to impeach him for perjury to a grand jury and voted 221–212 to impeach him for obstruction of justice. Clinton was only the second U.S. president (the first being Andrew Johnson) to be impeached. Impeachment proceedings were based on allegations that Clinton had illegally lied about and covered up his relationship with 22-year-old White House (and later Department of Defense) employee Monica Lewinsky. After the Starr Report was submitted to the House providing what it termed "substantial and credible information that President Clinton Committed Acts that May Constitute Grounds for an Impeachment", the House began impeachment hearings against Clinton before the mid-term elections. To hold impeachment proceedings, Republican leadership called a lame-duck session in December 1998. While the House Judiciary Committee hearings ended in a straight party-line vote, there was lively debate on the House floor. The two charges passed in the House (largely with Republican support, but with a handful of Democratic votes as well) were for perjury and obstruction of justice. The perjury charge arose from Clinton's testimony before a grand jury that had been convened to investigate perjury he may have committed in his sworn deposition during Jones v. Clinton, Paula Jones's sexual harassment lawsuit. The obstruction charge was based on his actions to conceal his relationship with Lewinsky before and after that deposition. The Senate later acquitted Clinton of both charges. The Senate refused to meet to hold an impeachment trial before the end of the old term, so the trial was held over until the next Congress. Clinton was represented by Washington law firm Williams & Connolly. The Senate finished a twenty-one-day trial on February 12, 1999, with the vote of 55 not guilty/45 guilty on the perjury charge and 50 not guilty/50 guilty on the obstruction of justice charge. Both votes fell short of the constitutional two-thirds majority requirement to convict and remove an officeholder. The final vote was generally along party lines, with no Democrats voting guilty, and only a handful of Republicans voting not guilty. On January 19, 2001, Clinton's law license was suspended for five years after he acknowledged to an Arkansas circuit court he had engaged in conduct prejudicial to the administration of justice in the Jones case. Pardons and commutations Clinton issued 141 pardons and 36 commutations on his last day in office on January 20, 2001. Controversy surrounded Marc Rich and allegations that Hillary Clinton's brother, Hugh Rodham, accepted payments in return for influencing the president's decision-making regarding the pardons. Federal prosecutor Mary Jo White was appointed to investigate the pardon of Rich. She was later replaced by then-Republican James Comey. The investigation found no wrongdoing on Clinton's part. Clinton also pardoned 4 defendants in the Whitewater Scandal, Chris Wade, Susan McDougal, Stephen Smith, and Robert W. Palmer, all of whom had ties to Clinton when he was governor of Arkansas. Former Clinton HUD Secretary Henry Cisneros, who pleaded guilty to lying to the FBI, was also among Clinton's pardons. Campaign finance controversies In February 1997 it was discovered upon documents being released by the Clinton Administration that 938 people had stayed at the White House and that 821 of them had made donations to the Democratic Party and got the opportunity to stay in the Lincoln bedroom as a result of the donations. Some donors included Steven Spielberg, Tom Hanks, Jane Fonda, and Judy Collins. Top donors also got golf games and morning jogs with Clinton as a result of the contributions. Janet Reno was called on to investigate the matter by Trent Lott, but she refused. In 1996, it was found that several Chinese foreigners made contributions to Clinton's reelection campaign and the Democratic National Committee with the backing of the People's Republic of China. Some of them also attempted to donate to Clinton's defense fund. This violated United States law forbidding non-American citizens from making campaign contributions. Clinton and Al Gore also allegedly met with the foreign donors. A Republican investigation led by Fred Thompson found that Clinton was targeted by the Chinese government. However, Democratic senators Joe Lieberman and John Glenn said that the evidence showed that China only targeted congressional elections and not presidential elections. Military and foreign affairs Somalia American troops had first entered Somalia during the Bush administration in response to a humanitarian crisis and civil war. Though initially involved to assist humanitarian efforts, the Clinton administration shifted the objectives set out in the mission and began pursuing a policy of attempting to neutralize Somali warlords. In 1993, during the Battle of Mogadishu, two U.S. helicopters were shot down by rocket-propelled grenade attacks to their tail rotors, trapping soldiers behind enemy lines. This resulted in an urban battle that killed 18 American soldiers, wounded 73 others, and resulted in one being taken prisoner. Television news programs depicted the supporters of warlord Mohammed Aidid desecrating the corpses of troops. The backlash resulting from the incident prompted in a drop in support for American intervention in the country and coincided with a more cautious use of troops throughout the rest of the Clinton administration. Following a subsequent national security policy review, U.S. forces were withdrawn from Somalia and later conflicts were approached with fewer soldiers on the ground. Rwanda In April 1994, genocide broke out in Rwanda. Intelligence reports indicate that Clinton was aware a "final solution to eliminate all Tutsis" was underway, long before the administration publicly used the word "genocide". Fearing a reprisal of the events in Somalia the previous year, Clinton chose not to intervene. Clinton has called his failure to intervene one of his main foreign policy failings, saying "I don't think we could have ended the violence, but I think we could have cut it down. And I regret it." Bosnia and Herzegovina In 1993 and 1994, Clinton pressured Western European leaders to adopt a strong military policy against Bosnian Serbs during the Bosnian War. This strategy faced staunch opposition from the United Nations, NATO allies, and Congressional Republicans, leading Clinton to adopt a more diplomatic approach. In 1995, U.S. and NATO aircraft bombed Bosnian Serb targets to halt attacks on UN safe zones and pressure them into a peace accord that would end the Bosnian war. Clinton deployed U.S. peacekeepers to Bosnia in late 1995, to uphold the subsequent Dayton Agreement. Irish peace talks In 1992, before his presidency, Clinton proposed sending a peace envoy to Northern Ireland, but this was dropped to avoid tensions with the British government. In November 1995, in a ceasefire during the Troubles, Clinton became the first president to visit Northern Ireland, examining both of the two divided communities of Belfast. Despite unionist criticism, Clinton used his visit as a way to negotiate an end to the violent conflict, playing a key role in the peace talks that produced the Good Friday Agreement in 1998. Iran Clinton sought to continue the Bush administration's policy of limiting Iranian influence in the Middle East, which he laid out in the dual containment strategy. In 1994, Clinton declared that Iran was a "state sponsor of terrorism" and a "rogue state", marking the first time that an American President used that term. Subsequent executive orders heavily sanctioned Iran's oil industry and banned almost all trade between U.S. companies and the Iranian government. In February 1996, the Clinton administration agreed to pay Iran US$131.8million (equivalent to $ million in ) in settlement to discontinue a case brought by Iran in 1989 against the U.S. in the International Court of Justice after the shooting down of Iran Air Flight 655 by the U.S. Navy guided missile cruiser. Following the 1997 election of reformist president Mohammad Khatami, the administration eased sanctions. Iraq In Clinton's 1998 State of the Union Address, he warned Congress that Iraqi dictator Saddam Hussein was building an arsenal of chemical, biological and nuclear weapons. Clinton signed the Iraq Liberation Act of 1998 on October 31, 1998, which instituted a policy of "regime change" against Iraq, though it explicitly stated it did not provide for direct intervention on the part of American military forces. The administration then launched a four-day bombing campaign named Operation Desert Fox, lasting from December 16 to 19, 1998. At the end of this operation Clinton announced that "So long as Saddam remains in power, he will remain a threat to his people, his region, and the world. With our allies, we must pursue a strategy to contain him and to constrain his weapons of mass destruction program, while working toward the day Iraq has a government willing to live at peace with its people and with its neighbors." American and British aircraft in the Iraq no-fly zones attacked hostile Iraqi air defenses 166 times in 1999 and 78 times in 2000. Osama bin Laden Capturing Osama bin Laden was an objective of the U.S. government during the Clinton presidency (and continued to be until bin Laden's death in 2011). Despite claims by Mansoor Ijaz and Sudanese officials that the Sudanese government had offered to arrest and extradite bin Laden, and that U.S. authorities rejected each offer, the 9/11 Commission Report stated that "we have not found any reliable evidence to support the Sudanese claim". In response to a 1996 State Department warning about bin Laden and the 1998 bombings of U.S. embassies in East Africa by al-Qaeda (which killed 224 people, including 12 Americans), Clinton ordered several military missions to capture or kill bin Laden, all of which were unsuccessful. In August 1998, Clinton ordered cruise missile strikes on terrorist targets in Afghanistan and Sudan, targeting the Al-Shifa pharmaceutical factory in Sudan, which was suspected of assisting bin Laden in making chemical weapons, and bin Laden's terrorist training camps in Afghanistan. The factory was destroyed by the attack, resulting in the death of one employee and the wounding of 11 other people. After the destruction of the factory, there was a medicine shortage in Sudan due to the plant providing 50 percent of Sudan's medicine, and the destruction of the plant led to a shortage of chloroquine, a drug which is used to treat malaria. U.S. officials later acknowledged that there was no evidence the plant was acknowledging manufacturing or storing nerve gas. The attack provoked criticism of Clinton from journalists and academics including Christopher Hitchens, Seymour Hersh, Max Taylor, and others. Kosovo In the midst of a brutal crackdown on ethnic Albanian separatists in the province of Kosovo by the Federal Republic of Yugoslavia, Clinton authorized the use of U.S. Armed Forces in a NATO bombing campaign against Yugoslavia in 1999, named Operation Allied Force. The stated reasoning behind the intervention was to stop the ethnic cleansing (and what the Clinton administration labeled genocide) of Albanians by Yugoslav anti-guerilla military units. General Wesley Clark was Supreme Allied Commander of NATO and oversaw the mission. With United Nations Security Council Resolution 1244, the bombing campaign ended on June 10, 1999. The resolution placed Kosovo under UN administration and authorized a peacekeeping force to be deployed to the region. NATO announced its soldiers all survived combat, though two died in an Apache helicopter crash. Journalists in the popular press criticized genocide statements by the Clinton administration as false and greatly exaggerated. Prior to the bombing campaign on March 24, 1999, estimates showed that the number of civilians killed in the over year long conflict in Kosovo had been approximately 1,800, with critics asserting that little or no evidence existed of genocide. In a post-war inquiry, the Organization for Security and Co-operation in Europe noted "the patterns of the expulsions and the vast increase in lootings, killings, rape, kidnappings and pillage once the NATO air war began on March 24." In 2001, the UN-supervised Supreme Court of Kosovo ruled that genocide (the intent to destroy a people) did not take place, but recognized "a systematic campaign of terror, including murders, rapes, arsons and severe maltreatments" with the intention being the forceful departure of the Albanian population. The term "ethnic cleansing" was used as an alternative to "genocide" to denote not just ethnically motivated murder but also displacement, though critics charge there is little difference. Slobodan Milošević, the president of Yugoslavia at the time of the atrocities, was eventually brought to trial before the International Criminal Tribunal for the former Yugoslavia in the Hague on charges including crimes against humanity and war crimes for his role in the war. He died in 2006, before the completion of the trial. China Clinton aimed to increase trade with China, minimizing import tariffs and offering the country most favoured nation status in 1993, his administration minimized tariff levels in Chinese imports. Clinton initially conditioned extension of this status on human rights reforms, but ultimately decided to extend the status despite a lack of reform in the specified areas, including free emigration, treatment of prisoners in terms of international human rights, and observation of human rights specified by UN resolutions, among others. Relations were damaged briefly by the American bombing of the Chinese embassy in Belgrade in May 1999. Clinton apologized for the bombing, stating it was accidental. On October 10, 2000, Clinton signed into law the United States–China Relations Act of 2000, which granted permanent normal trade relations (PNTR) trade status to China. The president asserted that free trade would gradually open China to democratic reform. In encouraging Congress to approve the agreement and China's accession to the World Trade Organization (WTO), Clinton stated that more trade with China would advance America's economic interests, saying that "economically, this agreement is the equivalent of a one-way street. It requires China to open its markets—with a fifth of the world's population, potentially the biggest markets in the world—to both our products and services in unprecedented new ways." Israeli-Palestinian conflict Clinton attempted to end the Israeli–Palestinian conflict. Secret negotiations mediated by Clinton between Israeli Prime Minister Yitzhak Rabin and Palestine Liberation Organization (PLO) Chairman Yasser Arafat led to a historic declaration of peace in September 1993, called the Oslo Accords, which were signed at the White House on September 13. The agreement led to the Israel–Jordan peace treaty in 1994 and the Wye River Memorandum in October 1998, however, this did not end the conflict. He brought Israeli prime minister Ehud Barak and Palestinian Authority chairman Yasser Arafat together at Camp David for the 2000 Camp David Summit, which lasted 14 days in July. Following the failure of the peace talks, Clinton said Arafat had "missed the opportunity" to facilitate a "just and lasting peace". In his autobiography, Clinton blames Arafat for the collapse of the summit. Following another attempt in December 2000 at Bolling Air Force Base, in which the president offered the Clinton Parameters, the situation broke down completely after the end of the Taba Summit and with the start of the Second Intifada. Judicial appointments Clinton appointed two justices to the Supreme Court: Ruth Bader Ginsburg in 1993 and Stephen Breyer in 1994. Both justices went on to serve until the 2020s, leaving a lasting judicial legacy for President Clinton. Clinton was the first president in history to appoint more women and minority judges than white male judges to the federal courts. In his eight years in office, 11.6% of Clinton's court of appeals nominees and 17.4% of his district court nominees were black; 32.8% of his court of appeals nominees and 28.5% of his district court nominees were women. Public opinion Throughout Clinton's first term, his job approval rating fluctuated in the 40s and 50s. In his second term, his rating consistently ranged from the high-50s to the high-60s. After his impeachment proceedings in 1998 and 1999, Clinton's rating reached its highest point. According to a CBS News/New York Times poll, Clinton left office with an approval rating of 68 percent, which matched those of Ronald Reagan and Franklin D. Roosevelt as the highest ratings for departing presidents in the modern era. Clinton's average Gallup poll approval rating for his last quarter in office was 61 percent, the highest final quarter rating any president has received for fifty years. Forty-seven percent of the respondents identified themselves as being Clinton supporters. As he was leaving office, a CNN/USA Today/Gallup poll revealed that 45 percent of Americans said they would miss him; 55 percent thought he "would have something worthwhile to contribute and should remain active in public life"; 68 percent thought he would be remembered more for his "involvement in personal scandal" than for "his accomplishments"; and 58 percent answered "No" to the question "Do you generally think Bill Clinton is honest and trustworthy?" The same percentage said he would be remembered as either "outstanding" or "above average" as a president, while 22 percent said he would be remembered as "below average" or "poor". ABC News characterized public consensus on Clinton as, "You can't trust him, he's got weak morals and ethics—and he's done a heck of a good job." In May 2006, a CNN poll comparing Clinton's job performance with that of his successor, George W. Bush, found that a strong majority of respondents said Clinton outperformed Bush in six different areas questioned. Gallup polls in 2007 and 2011 showed that Clinton was regarded by 13 percent of Americans as the greatest president in U.S. history. In 2014, 18 percent of respondents in a Quinnipiac University Polling Institute poll of American voters regarded Clinton as the best president since World War II, making him the third most popular among postwar presidents, behind John F. Kennedy and Ronald Reagan. The same poll showed that just 3 percent of American voters regarded Clinton as the worst president since World War II. A 2015 poll by The Washington Post asked 162 scholars of the American Political Science Association to rank all the U.S. presidents in order of greatness. According to their findings, Clinton ranked eighth overall, with a rating of 70 percent. Public image Clinton was the first baby boomer president. Authors Martin Walker and Bob Woodward stated that Clinton's innovative use of sound bite-ready dialogue, personal charisma, and public perception-oriented campaigning were a major factor in his high public approval ratings. When Clinton played the saxophone on The Arsenio Hall Show, he was described by some religious conservatives as "the MTV president". Opponents sometimes referred to him as "Slick Willie", a nickname which was first applied to him in 1980 by Pine Bluff Commercial journalist Paul Greenberg; Greenberg believed that Clinton was abandoning the progressive policies of previous Arkansas Governors such as Winthrop Rockefeller, Dale Bumpers and David Pryor. The claim "Slick Willie" would last throughout his presidency. His folksy manner led him to be nicknamed Bubba, especially in the South, starting from the 1992 presidential election. Since 2000, he has frequently been referred to as "The Big Dog" or "Big Dog". His prominent role in campaigning for President Obama during the 2012 presidential election and his widely publicized speech at the 2012 Democratic National Convention, where he officially nominated Obama and criticized Republican nominee Mitt Romney and Republican policies in detail, earned him the nickname "Explainer-in-Chief". Clinton drew strong support from the African American community and insisted that the improvement of race relations would be a major theme of his presidency. In 1998, Nobel laureate Toni Morrison called Clinton "the first black president", saying, "Clinton displays almost every trope of blackness: single-parent household, born poor, working-class, saxophone-playing, McDonald's-and-junk-food-loving boy from Arkansas". Morrison noted that Clinton's sex life was scrutinized more than his career accomplishments, and she compared this to the stereotyping and double standards that, she said, blacks typically endure. Many viewed this comparison as unfair and disparaging both to Clinton and to the African-American community. Sexual assault and misconduct allegations Several women have publicly accused Bill Clinton of sexual misconduct, including rape, harassment, and sexual assault. Additionally, some commentators have characterized Clinton's sexual relationship with former White House intern Monica Lewinsky as predatory or non-consensual, despite the fact that Lewinsky called the relationship consensual at the time. These allegations have been revisited and lent more credence in 2018, in light of the #MeToo movement, with many commentators and Democratic leaders now saying Clinton should have been compelled to resign after the Lewinsky affair. In 1994, Paula Jones initiated a sexual harassment lawsuit against Clinton, claiming he had made unwanted advances towards her in 1991; Clinton denied the allegations. In April 1998, the case was initially dismissed by Judge Susan Webber Wright on the grounds that it lacked legal merit. Jones appealed Webber Wright's ruling, and her suit gained traction following Clinton's admission to having an affair with Monica Lewinsky in August 1998. In 1998, lawyers for Paula Jones released court documents that alleged a pattern of sexual harassment by Clinton when he was Governor of Arkansas. Robert S. Bennett, Clinton's main lawyer for the case, called the filing "a pack of lies" and "an organized campaign to smear the President of the United States" funded by Clinton's political enemies. Clinton later agreed to an out-of-court settlement and paid Jones $850,000. Bennett said the president made the settlement only so he could end the lawsuit for good and move on with his life. During the deposition for the Jones lawsuit, which was held at the White House, Clinton denied having sexual relations with Monica Lewinsky—a denial that became the basis for an impeachment charge of perjury. In 1998, Kathleen Willey alleged that Clinton had groped her in a hallway in 1993. An independent counsel determined Willey gave "false information" to the FBI, inconsistent with sworn testimony related to the Jones allegation. On March 19, 1998, Julie Hiatt Steele, a friend of Willey, released an affidavit, accusing the former White House aide of asking her to lie to corroborate Ms. Willey's account of being sexually groped by Clinton in the Oval Office. An attempt by Kenneth Starr to prosecute Steele for making false statements and obstructing justice ended in a mistrial and Starr declined to seek a retrial after Steele sought an investigation against the former independent counsel for prosecutorial misconduct. Linda Tripp's grand jury testimony also differed from Willey's claims regarding inappropriate sexual advances. Also in 1998, Juanita Broaddrick alleged that Clinton had raped her in the spring of 1978, although she said she did not remember the exact date. To support her charge, Broaddrick notes that she told multiple witnesses in 1978 she had been raped by Clinton, something these witnesses also state in interviews to the press. Broaddrick had earlier filed an affidavit denying any "unwelcome sexual advances" and later repeated the denial in a sworn deposition. In a 1998 NBC interview wherein she detailed the alleged rape, Broaddrick said she had denied (under oath) being raped only to avoid testifying about the ordeal publicly. The Lewinsky scandal has had an enduring impact on Clinton's legacy, beyond his impeachment in 1998. In the wake of the #MeToo movement (which shed light on the widespread prevalence of sexual assault and harassment, especially in the workplace), various commentators and Democratic political leaders, as well as Lewinsky herself, have revisited their view that the Lewinsky affair was consensual, and instead characterized it as an abuse of power or harassment, in light of the power differential between a president and a 22-year old intern. In 2018, Clinton was asked in several interviews about whether he should have resigned, and he said he had made the right decision in not resigning. During the 2018 Congressional elections, The New York Times alleged that having no Democratic candidate for office asking Clinton to campaign with them was a change that attributed to the revised understanding of the Lewinsky scandal. However, former DNC interim chair Donna Brazile previously urged Clinton in November 2017 to campaign during the 2018 midterm elections, in spite of New York U.S. senator Kirsten Gillibrand's recent criticism of the Lewinsky scandal. Alleged affairs Clinton admitted to having extramarital affairs with singer Gennifer Flowers and Monica Lewinsky. Actress Elizabeth Gracen, Miss Arkansas winner Sally Perdue, and Dolly Kyle Browning all claimed that they had affairs with Clinton during his time as governor of Arkansas. Browning later sued Clinton, Bruce Lindsey, Robert S. Bennett, and Jane Mayer, alleging they engaged in a conspiracy to attempt to block her from publishing a book loosely based on her relationship with Clinton and tried to defame him. However, Browning's lawsuit was dismissed. Post-presidency (2001–present) Bill Clinton has continued to be active in public life since leaving office in 2001, giving speeches, fundraising, and founding charitable organizations, and has spoken in prime time at every Democratic National Convention. Activities until 2008 campaign In 2002, Clinton warned that pre-emptive military action against Iraq would have unwelcome consequences, and later claimed to have opposed the Iraq War from the start (though some dispute this). In 2005, Clinton criticized the Bush administration for its handling of emissions control, while speaking at the United Nations Climate Change conference in Montreal. The William J. Clinton Presidential Center and Park in Little Rock, Arkansas, was dedicated in 2004. Clinton released a best-selling autobiography, My Life, in 2004. In 2007, he released Giving: How Each of Us Can Change the World, which also became a New York Times Best Seller and garnered positive reviews. In the aftermath of the 2004 Asian tsunami, U.N. secretary-general Kofi Annan appointed Clinton to head a relief effort. After Hurricane Katrina, Clinton joined with fellow former president George H. W. Bush to establish the Bush-Clinton Tsunami Fund in January 2005, and the Bush-Clinton Katrina Fund in October of that year. As part of the tsunami effort, these two ex-presidents appeared in a Super Bowl XXXIX pre-game show, and traveled to the affected areas. They also spoke together at the funeral of Boris Yeltsin in April 2007. Based on his philanthropic worldview, Clinton created the William J. Clinton Foundation to address issues of global importance. This foundation includes the Clinton Foundation HIV and AIDS Initiative (CHAI), which strives to combat that disease, and has worked with the Australian government toward that end. The Clinton Global Initiative (CGI), begun by the Clinton Foundation in 2005, attempts to address world problems such as global public health, poverty alleviation and religious and ethnic conflict. In 2005, Clinton announced through his foundation an agreement with manufacturers to stop selling sugary drinks in schools. Clinton's foundation joined with the Large Cities Climate Leadership Group in 2006 to improve cooperation among those cities, and he met with foreign leaders to promote this initiative. The foundation has received donations from many governments all over the world, including Asia and the Middle East. In 2008, Foundation director Inder Singh announced deals to reduce the price of anti-malaria drugs by 30 percent in developing nations. Clinton also spoke in favor of California Proposition 87 on alternative energy, which was voted down. 2008 presidential election During the 2008 Democratic presidential primary campaign, Clinton vigorously advocated on behalf of his wife, Hillary. Through speaking engagements and fundraisers, he was able to raise $10 million toward her campaign. Some worried that as an ex-president, he was too active on the trail, too negative to Clinton rival Barack Obama, and alienating his supporters at home and abroad. Many were especially critical of him following his remarks in the South Carolina primary, which Obama won. Later in the 2008 primaries, there was some infighting between Bill and Hillary's staffs, especially in Pennsylvania. Considering Bill's remarks, many thought he could not rally Hillary supporters behind Obama after Obama won the primary. Such remarks led to apprehension that the party would be split to the detriment of Obama's election. Fears were allayed August 27, 2008, when Clinton enthusiastically endorsed Obama at the 2008 Democratic National Convention, saying all his experience as president assures him that Obama is "ready to lead". After Hillary Clinton's presidential campaign was over, Bill Clinton continued to raise funds to help pay off her campaign debt. After the 2008 election In 2009, Clinton travelled to North Korea on behalf of two American journalists imprisoned there. Euna Lee and Laura Ling had been imprisoned for illegally entering the country from China. Jimmy Carter had made a similar visit in 1994. After Clinton met with North Korean leader Kim Jong-il, Kim issued a pardon. Since then, Clinton has been assigned many other diplomatic missions. He was named United Nations Special Envoy to Haiti in 2009 following a series of hurricanes which caused $1 billion in damages. Clinton organized a conference with the Inter-American Development Bank, where a new industrial park was discussed in an effort to "build back better". In response to the 2010 Haiti earthquake, U.S. president Barack Obama announced that Clinton and George W. Bush would coordinate efforts to raise funds for Haiti's recovery. Funds began pouring into Haiti, which led to funding becoming available for Caracol Industrial Park in a part of the country unaffected by the earthquake. While Hillary Clinton was in South Korea, she and Cheryl Mills worked to convince SAE-A, a large apparel subcontractor, to invest in Haiti despite the company's deep concerns about plans to raise the minimum wage. In the summer of 2010, the South Korean company signed a contract at the U.S. State Department, ensuring that the new industrial park would have a key tenant. In 2010, Clinton announced support of, and delivered the keynote address for, the inauguration of NTR, Ireland's first environmental foundation. At the 2012 Democratic National Convention, Clinton gave a widely praised speech nominating Barack Obama. 2016 presidential election and after During the 2016 presidential election, Clinton again encouraged voters to support Hillary, and made appearances speaking on the campaign trail. In a series of tweets, then-President-elect Donald Trump criticized his ability to get people out to vote. Clinton served as a member of the electoral college for the state of New York. He voted for the Democratic ticket consisting of his wife Hillary and her running-mate Tim Kaine. On September 7, 2017, Clinton partnered with former presidents Jimmy Carter, George H. W. Bush, George W. Bush, and Barack Obama to work with One America Appeal to help the victims of Hurricane Harvey and Hurricane Irma in the Gulf Coast and Texas communities. In 2020, Clinton again served as a member of the United States Electoral College from New York, casting his vote for the successful Democratic ticket of Joe Biden and Kamala Harris. Post-presidential health concerns In September 2004, Clinton underwent quadruple bypass surgery. In March 2005, he again underwent surgery, this time for a partially collapsed lung. On February 11, 2010, he was rushed to New York-Presbyterian/Columbia Hospital in Manhattan after complaining of chest pains, and he had two coronary stents implanted in his heart. After this procedure, Clinton adopted a plant-based whole foods (vegan) diet, which had been recommended by doctors Dean Ornish and Caldwell Esselstyn. However, he has since incorporated fish and lean proteins at the suggestion of Mark Hyman, a proponent of the pseudoscientific ethos of functional medicine. As a result, he is no longer a strict vegan. In October 2021, Clinton was treated for sepsis at the University of California, Irvine Medical Center. In December 2022, Clinton tested positive for COVID-19. Wealth The Clintons incurred several million dollars in legal bills during his presidency, which were paid off four years after he left office. Bill and Hillary Clinton have each earned millions of dollars from book publishing. In 2016, Forbes reported Bill and Hillary Clinton made about $240million in the 15years from January 2001, to December 2015, (mostly from paid speeches, business consulting and book-writing). Also in 2016, CNN reported the Clintons combined to receive more than $153million in paid speeches from 2001 until spring 2015. In May 2015, The Hill reported that Bill and Hillary Clinton have made more than $25million in speaking fees since the start of 2014, and that Hillary Clinton also made $5million or more from her book, Hard Choices, during the same time period. In July 2014, The Wall Street Journal reported that at the end of 2012, the Clintons were worth between $5million and $25.5million, and that in 2012 (the last year they were required to disclose the information) the Clintons made between $16 and $17million, mostly from speaking fees earned by the former president. Clinton earned more than $104million from paid speeches between 2001 and 2012. In June 2014, ABC News and The Washington Post reported that Bill Clinton has made more than $100million giving paid speeches since leaving public office, and in 2008, The New York Times reported that the Clintons' income tax returns show they made $109million in the eight years from January 1, 2000, to December 31, 2007, including almost $92million from his speaking and book-writing. Bill Clinton has given dozens of paid speeches each year since leaving office in 2001, mostly to corporations and philanthropic groups in North America and Europe; he often earned $100,000 to $300,000 per speech. Russian investment bank with ties to the Kremlin paid Clinton $500,000 for a speech in Moscow. Hillary Clinton said she and Bill came out of the White House financially "broke" and in debt, especially due to large legal fees incurred during their years in the White House. "We had no money when we got there, and we struggled to, you know, piece together the resources for mortgages, for houses, for Chelsea's education". She added, "Bill has worked really hard ... we had to pay off all our debts ... he had to make double the money because of, obviously, taxes; and then pay off the debts, and get us houses, and take care of family members". Relationship with Jeffrey Epstein In the early 2000s, Clinton took flights on Jeffrey Epstein's private jet in connection with Clinton Foundation work. According to Epstein's attorney Gerald B. Lefcourt, Epstein was "part of the original group that conceived of the Clinton Global Initiative". In 2002, a spokesperson for Clinton praised Epstein as "a committed philanthropist" with "insights and generosity". While Clinton was president Epstein visited the White House at least 17 times. Years later, Epstein was convicted on sex trafficking charges. Clinton's office released a statement in 2019 saying, "President Clinton knows nothing about the terrible crimes Jeffrey Epstein pleaded guilty to in Florida some years ago, or those with which he has been recently charged in New York. In 2002 and 2003, President Clinton took four trips on Jeffrey Epstein's airplane: one to Europe, one to Asia, and two to Africa, which included stops in connection with the work of the Clinton Foundation. Staff, supporters of the Foundation, and his Secret Service detail traveled on every leg of every trip. [...] He's not spoken to Epstein in well over a decade." However, later reports showed that Clinton had flown on Epstein's plane 26 times. In another statement Clinton said "one meeting with Epstein in his Harlem office in 2002, and around the same time made one brief visit to Epstein's New York apartment with a staff member and his security detail". In July 2019 it was reported that Clinton attended a dinner with Epstein in 1995, a meeting with Epstein that Clinton had not previously disclosed. Clinton reportedly used Epstein's private jet to visit Little St. James Island, where Epstein resided. on multiple occasions between 2002 and 2005. Virginia Roberts, later known as Virginia Giuffre, says in a lawsuit that while working at Donald Trump's Mar-a-Lago resort she was lured into a sex-trafficking ring run by Epstein and while traveling with Epstein she saw Clinton on the island. In a 2011 conversation with her lawyers, Roberts stated that Clinton traveled to Epstein's retreat on Little St. James in 2002. A Freedom of Information Act request for United States Secret Service records of visits Clinton may have made to Little St. James produced no such evidence. According to Epstein's flight logs, Clinton never flew near the U.S. Virgin Islands. In July 2019, a Clinton spokesperson issued a statement saying Clinton never visited the island. Personal life At the age of 10, he was baptized at Park Place Baptist Church in Hot Springs, Arkansas. His faith grew cold during his university studies. In 1980, after participating in a pilgrimage to Israel led by Pastor W. O. Vaught, he became a member of his church, Immanuel Baptist Church Little Rock. When he became president in 1993, he became a member of Foundry United Methodist Church in Washington, D.C. with his wife, a Methodist. On October 11, 1975, in Fayetteville, Arkansas, he married Hillary Rodham, whom he met while studying at Yale University. They had Chelsea Clinton, their only child, on February 27, 1980. He is the maternal grandfather to Chelsea's three children. Honors and recognition Various colleges and universities have awarded Clinton honorary degrees, including Doctorate of Law degrees and Doctor of Humane Letters degrees. He received an honorary degree from Georgetown University, his alma mater, and was the commencement speaker in 1980. He is an honorary fellow of University College, Oxford, which he attended as a Rhodes Scholar, although he did not complete his studies there. Schools have been named for Clinton, and statues have been built to pay him homage. U.S. states where he has been honored include Missouri, Arkansas, Kentucky, and New York. He was presented with the Medal for Distinguished Public Service by Secretary of Defense William Cohen in 2001. The Clinton Presidential Center was opened in Little Rock, Arkansas, in his honor on December 5, 2001. He has been honored in various other ways, in countries that include the Czech Republic, Papua New Guinea, Germany, and Kosovo. The Republic of Kosovo, in gratitude for his help during the Kosovo War, renamed a major street in the capital city of Pristina as Bill Clinton Boulevard and added a monumental Clinton statue. Clinton was selected as Time "Man of the Year" in 1992, and again in 1998, along with Ken Starr. From a poll conducted of the American people in December 1999, Clinton was among eighteen included in Gallup's List of Most Widely Admired People of the 20th Century. In 2001, Clinton received the NAACP's President's Award. He has also been honored with a Grammy Award for Best Spoken Word Album for Children, a J. William Fulbright Prize for International Understanding, a TED Prize (named for the confluence of technology, entertainment and design), and was named as an Honorary GLAAD Media Award recipient for his work as an advocate for the LGBT community. In 2011, President Michel Martelly of Haiti awarded Clinton with the National Order of Honour and Merit to the rank of Grand Cross "for his various initiatives in Haiti and especially his high contribution to the reconstruction of the country after the earthquake of January 12, 2010". Clinton declared at the ceremony that "in the United States of America, I really don't believe former American presidents need awards anymore, but I am very honored by this one, I love Haiti, and I believe in its promise". U.S. president Barack Obama awarded Clinton the Presidential Medal of Freedom on November 20, 2013. Authored books Recordings Bill Clinton is one of the narrators on Wolf Tracks and Peter and the Wolf, a 2003 recording of Sergei Prokofiev's Peter and the Wolf performed by the Russian National Orchestra, on Pentatone, together with Mikhail Gorbachev and Sophia Loren. This garnered Clinton the 2003 Grammy Award for Best Spoken Word Album for Children. The audiobook edition of his autobiography, My Life, read by Clinton himself, won the 2005 Grammy Award for Best Spoken Word Album as well as the Audie Award as the Audiobook of the Year. Clinton has two more Grammy nominations for his audiobooks: Giving: How Each of Us Can Change the World in 2007 and Back to Work in 2012.

Black letter law

In common law legal systems, black-letter law refers to well-established legal rules that are no longer subject to reasonable dispute. For example, it is "black-letter law" that the formation of a contract requires consideration, or that the registration of a trademark requires established use in the course of trade. Black-letter law can be contrasted with legal theory or unsettled legal issues. History and etymology In an 1831 case in the U.S. Supreme Court, Jackson ex dem. Bradstreet v. Huntington, the phrase "black letter" was used: "It is seldom that a case in our time savours so much of the black letter; but the course of decisions in New York renders it unavoidable...". The phrase "black-letter law" was used in the Pennsylvania Supreme Court case Naglee v. Ingersoll, 7 Pa. 185 (1847). The phrase does not come from association with Black's Law Dictionary, which was first published in 1891. Instead, it refers to the practice of setting law books and citing legal precedents in blackletter type, a tradition that survived long after the switch to Roman and italic text for other printed works. The phrase definitely refers to a distillation of the common law into general and accepted legal principles. This can be seen in the quote above from the Supreme Court where the court is noting that while the black letter law is clear, New York precedent deviates from the general principles. In the common law, the informal notion of black letter law includes the basic principles of law generally accepted by the courts and/or embodied in the statutes of a particular jurisdiction. The letter of the law is its actual implementation, thereby demonstrating that black letter laws are those statutes, rules, acts, laws, provisions, etc. that are or have been written down, codified, or indicated somewhere in legal texts throughout history of specific state law. This is often the case for many precedents that have been set in the common law. An example of such a state within the common law jurisdiction, and using the black letter legal doctrine is Canada. Canada is a monarchical state, with its roots invested in Colonial England, and black letter law is the principles of law accepted by the majority of judges in most provinces and territories. Sometimes it is referred to as "hornbook law" meaning treatise or textbook, often relied upon as authoritative, competent, and generally accepted in the field of Canadian law. In lawyer lingo, hornbook law or black letter law is a fundamental and well-accepted legal principle that does not require any further explanation, since a hornbook is a primer of basics. Law is the rule which establish that a principle, provision, references, inference, observation, etc. may not require further explanation or clarification when the very nature of them shows that they are basic and elementary. Similar phrases The phrase is nearly synonymous with the phrase "hornbook law". There are a number of venerable legal sources that distill the common law on various subjects known as Restatement of the Law. The specific titles will be "The Restatement (First) of Contracts" or "The Restatement of Agency" etc. Each of these volumes is divided into sections that begin with a text in boldface that summarizes a basic rule on an aspect of the law of contracts, agency etc. This "restatement" is followed by commentary and examples that expand on the principle stated. Another synonymous term, usually used in the United Kingdom is "trite law". References Informal legal terminology

Beer

Beer is one of the oldest types of alcoholic drinks in the world, and the most widely consumed. It is the third most popular drink overall after potable water and tea. It is produced by the brewing and fermentation of starches, mainly derived from cereal grains—most commonly malted barley, though wheat, maize (corn), rice, and oats are also used. During the brewing process, fermentation of the starch sugars in the wort produces ethanol and carbonation in the resulting beer. Most modern beer is brewed with hops, which add bitterness and other flavours and act as a natural preservative and stabilising agent. Other flavouring agents such as gruit, herbs, or fruits may be included or used instead of hops. In commercial brewing, the natural carbonation effect is often removed during processing and replaced with forced carbonation. Some of humanity's earliest known writings refer to the production and distribution of beer: the Code of Hammurabi included laws regulating beer and beer parlours, and "The Hymn to Ninkasi", a prayer to the Mesopotamian goddess of beer, served as both a prayer and as a method of remembering the recipe for beer in a culture with few literate people. Beer is distributed in bottles and cans and is also commonly available on draught, particularly in pubs and bars. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. The strength of modern beer is usually around 4% to 6% alcohol by volume (ABV), although it may vary between 0.5% and 20%, with some breweries creating examples of 40% ABV and above. Beer forms part of the culture of many nations and is associated with social traditions such as beer festivals, as well as a rich pub culture involving activities like pub crawling, pub quizzes and pub games. When beer is distilled, the resulting liquor is a form of whisky. Etymology In early forms of English and in the Scandinavian languages, the usual word for beer was the word whose Modern English form is ale. The word beer comes into present-day English from Old English , itself from Common Germanic; although the word is not attested in the East Germanic branch of the language family, it is found throughout the West Germanic and North Germanic dialects (modern Dutch and German , Old Norse ). The earlier etymology of the word is debated: the three main theories are that the word originates in Proto-Germanic (putatively from Proto-Indo-European ), meaning 'brewer's yeast, beer dregs'; that it is related to the word barley, or that it was somehow borrowed from Latin 'to drink'. In Old English and Old Norse, the beer-word did not denote a malted alcoholic drink like ale, but a sweet, potent drink made from honey and the juice of one or more fruits other than grapes, much less ubiquitous than ale, perhaps served in the kind of tiny drinking cups sometimes found in early mediaeval grave goods: a drink more like mead or cider. In German, however, the meaning of the beer-word expanded to cover the meaning of the ale-word already before our earliest surviving written evidence. As German hopped ale became fashionable in England in the late Middle Ages, the English word beer took on the German meaning, and thus in English too, beer came during the early modern period to denote hopped, malt-based alcoholic drinks. History Beer is one of the world's oldest prepared alcoholic drinks. The earliest archaeological evidence of fermentation consists of 13,000 year-old residues of a beer with the consistency of gruel, used by the semi-nomadic Natufians for ritual feasting, at the Raqefet Cave in the Carmel Mountains near Haifa in Israel. There is evidence that beer was produced at Göbekli Tepe during the Pre-Pottery Neolithic (around 8500  to 5500 ). The earliest clear chemical evidence of beer produced from barley dates to about 3500–3100 , from the site of Godin Tepe in the Zagros Mountains of western Iran. It is possible, but not proven, that it dates back even further – to about 10,000 , when cereal was first farmed. Beer is recorded in the written history of ancient Egypt, and archaeologists speculate that beer was instrumental in the formation of civilizations. Approximately 5000 years ago, workers in the city of Uruk (modern day Iraq) were paid by their employers with volumes of beer. During the building of the Great Pyramids in Giza, Egypt, each worker got a daily ration of four to five litres of beer, which served as both nutrition and refreshment and was crucial to the pyramids' construction. Some of the earliest Sumerian writings contain references to beer; examples include a prayer to the goddess Ninkasi, known as "The Hymn to Ninkasi", which served as both a prayer and a method of remembering the recipe for beer in a culture with few literate people, and the ancient advice ("Fill your belly. Day and night make merry") to Gilgamesh, recorded in the Epic of Gilgamesh by the alewife Siduri, may, at least in part, have referred to the consumption of beer. The Ebla tablets, discovered in 1974 in Ebla, Syria, show that beer was produced in the city in 2500 BC. A fermented drink using rice and fruit was made in China around 7000 BC. Unlike sake, mould was not used to saccharify the rice (amylolytic fermentation); the rice was probably prepared for fermentation by chewing or malting. During the Vedic period in Ancient India, there are records of the consumption of the beer-like sura. Xenophon noted that during his travels, beer was being produced in Armenia. Almost any substance containing sugar can naturally undergo alcoholic fermentation and thus be utilised in the brewing of beer. It is likely that many cultures, on observing that a sweet liquid could be obtained from a source of starch, independently invented beer. Bread and beer increased prosperity to a level that allowed time for the development of other technologies and contributed to the building of civilizations. Beer was spread through Europe by Germanic and Celtic tribes as far back as 3000 BC, and it was mainly brewed on a domestic scale. The product that the early Europeans drank might not be recognised as beer by most people today. Alongside the basic starch source, the early European beers may have contained fruits, honey, numerous types of plants, spices, and other substances such as narcotic herbs. What they did not contain was hops, as that was a later addition, first mentioned in Europe around 822 by a Carolingian Abbot and again in 1067 by abbess Hildegard of Bingen. In 1516, William IV, Duke of Bavaria, adopted the Reinheitsgebot (purity law), perhaps the oldest food-quality regulation still in use in the 21st century, according to which the only allowed ingredients of beer are water, hops, and barley-malt. Beer produced before the Industrial Revolution continued to be made and sold on a domestic scale, although by the 7th century , beer was also being produced and sold by European monasteries. During the Industrial Revolution, the production of beer moved from artisanal manufacture to industrial manufacture, and domestic manufacture ceased to be significant by the end of the 19th century. The development of hydrometers and thermometers changed brewing by allowing the brewer more control of the process and greater knowledge of the results. In 1912, brown bottles began to be used by the Joseph Schlitz Brewing Company of Milwaukee, Wisconsin, in the United States. This innovation has since been accepted worldwide and prevents harmful rays from destroying the quality and stability of beer. The brewing industry is now a global business, consisting of several dominant multinational companies and many thousands of smaller producers, ranging from brewpubs to regional breweries. As of 2006, more than , the equivalent of a cube 510 metres on a side, of beer are sold per year, producing total global revenues of US$294.5 billion. In 2010, China's beer consumption hit , or nearly twice that of the United States, but only 5 per cent sold were premium draught beers, compared with 50 per cent in France and Germany. A widely publicised study in 2018 suggested that sudden decreases in barley production due to extreme drought and heat could in the future cause substantial volatility in the availability and price of beer. Brewing The process of making beer is known as brewing. A dedicated building for the making of beer is called a brewery, though beer can be made at home and has been for much of its history, in which case the brewing location is often called a brewhouse. A company that makes beer is called either a brewery or a brewing company. Beer made on a domestic scale for non-commercial reasons is today usually classified as homebrewing, regardless of where it is made, though most homebrewed beer is made at home. Historically, domestic beer was what's called farmhouse ale. Brewing beer has been subject to legislation and taxation for millennia, and from the late 19th century on, taxation largely restricted brewing to commercial operations only in the UK. However, the UK government relaxed legislation in 1963, followed by Australia in 1972 and the US in 1978, though individual states were allowed to pass their own laws limiting production, allowing homebrewing to become a popular hobby. The purpose of brewing is to convert the starch source into a sugary liquid called wort and to convert the wort into the alcoholic drink known as beer in a fermentation process effected by yeast. The first step, where the wort is prepared by mixing the starch source (normally malted barley) with hot water, is known as "mashing". Hot water (known as "liquor" in brewing terms) is mixed with crushed malt or malts (known as "grist") in a mash tun. The mashing process takes around 1 to 2 hours, during which the starches are converted to sugars, and then the sweet wort is drained off the grains. The grains are then washed in a process known as "sparging". This washing allows the brewer to gather as much of the fermentable liquid from the grains as possible. The process of filtering the spent grain from the wort and sparge water is called wort separation. The traditional process for wort separation is lautering, in which the grain bed itself serves as the filter medium. Some modern breweries prefer the use of filter frames, which allow for a more finely ground grist. Most modern breweries use a continuous sparge, collecting the original wort and the sparge water together. However, it is possible to collect a second or even third wash with the not quite spent grains as separate batches. Each run would produce a weaker wort and thus, a weaker beer. This process is known as the second (and third) runnings. Brewing with several runnings is called parti gyle brewing. The sweet wort collected from sparging is put into a kettle, or "copper" (so-called because these vessels were traditionally made from copper), and boiled, usually for about one hour. During boiling, the water in the wort evaporates, but the sugars and other components of the wort remain; this allows more efficient use of the starch sources in the beer. Boiling also destroys any remaining enzymes left over from the mashing stage. Hops are added during boiling as a source of bitterness, flavour, and aroma. Hops may be added at more than one point during the boil. The longer the hops are boiled, the more bitterness they contribute, but the less hop flavour and aroma remain in the beer. After boiling, the hopped wort is cooled and ready for the yeast. In some breweries, the hopped wort may pass through a hopback, which is a small vat filled with hops, to add aromatic hop flavouring and to act as a filter, but usually the hopped wort is simply cooled for the fermenter, where the yeast is added. During fermentation, the wort becomes beer in a process that takes a week to several months, depending on the type of yeast and strength of the beer. In addition to producing ethanol, fine particulate matter suspended in the wort settles during fermentation. Once fermentation is complete, the yeast also settles, leaving the beer clear. During fermentation, most of the carbon dioxide is allowed to escape through a trap, and the beer is left with carbonation of only about one atmosphere of pressure. The carbonation is often increased either by transferring the beer to a pressure vessel such as a keg and introducing pressurised carbon dioxide or by transferring it before the fermentation is finished so that carbon dioxide pressure builds up inside the container as the fermentation finishes. Sometimes the beer is put unfiltered (so it still contains yeast) into bottles with some added sugar, which then produces the desired amount of carbon dioxide inside the bottle. Fermentation is sometimes carried out in two stages: primary and secondary. Once most of the alcohol has been produced during primary fermentation, the beer is transferred to a new vessel and allowed a period of secondary fermentation. Secondary fermentation is used when the beer requires long storage before packaging or greater clarity. When the beer has fermented, it is packaged either into casks for cask ale or kegs, aluminium cans, or bottles for other sorts of beer. Ingredients The basic ingredients of beer are water; a starch source, such as malted barley or malted maize (such as used in the preparation of Tiswin and Tesgüino), able to be saccharified (converted to sugars) and then fermented (converted into ethanol and carbon dioxide); a brewer's yeast to produce the fermentation; and a flavouring such as hops. A mixture of starch sources may be used, with a secondary carbohydrate source, such as maize (corn), rice, wheat, or sugar, often termed an adjunct, especially when used alongside malted barley. Less widely used starch sources include millet, sorghum, and cassava root in Africa; potato in Brazil; and agave in Mexico, among others. The amount of each starch source in a beer recipe is collectively called the grain bill. Water is the main ingredient in beer, accounting for 93% of its weight. Though water itself is, ideally, flavourless, its level of dissolved minerals, specifically bicarbonate ions, does influence beer's finished taste. Due to the mineral properties of each region's water, specific areas were originally the sole producers of certain types of beer, each identifiable by regional characteristics. Regional geology accords that Dublin's hard water is well-suited to making stout, such as Guinness, while the Plzeň Region's soft water is ideal for brewing Pilsner (pale lager), such as Pilsner Urquell. The waters of Burton in England contain gypsum, which benefits making pale ale to such a degree that brewers of pale ales will add gypsum to the local water in a process known as Burtonisation. The starch source, termed the "mash ingredients", in a beer provides the fermentable material and is a key determinant of the strength and flavour of the beer. The most common starch source used in beer is malted grain. Grain is malted by soaking it in water, allowing it to begin germination, and then drying the partially germinated grain in a kiln. Malting grain produces enzymes that convert starches in the grain into fermentable sugars. Different roasting times and temperatures are used to produce different colours of malt from the same grain. Darker malts will produce darker beers. Nearly all beers include barley malt as the majority of the starch. This is because its fibrous hull remains attached to the grain during threshing. After malting, barley is milled, which finally removes the hull, breaking it into large pieces. These pieces remain with the grain during the mash and act as a filter bed during lautering, when sweet wort is separated from insoluble grain material. Other malted and unmalted grains (including wheat, rice, oats, and rye, and less frequently, corn and sorghum) may be used. Some brewers have produced gluten-free beer, made with sorghum with no barley malt, for those who cannot consume gluten-containing grains like wheat, barley, and rye. Flavouring beer is the sole major commercial use of hops. The flower of the hop vine is used as a flavouring and preservative agent in nearly all beer made today. The flowers themselves are often called "hops". The first historical mention of the use of hops in beer dates from 822 AD in monastery rules written by Adalhard the Elder, also known as Adalard of Corbie, though the date normally given for widespread cultivation of hops for use in beer is the thirteenth century. Before the thirteenth century and until the sixteenth century, during which hops took over as the dominant flavouring, beer was flavoured with other plants, for instance, grains of paradise or alehoof. Combinations of various aromatic herbs, berries, and even ingredients like wormwood would be combined into a mixture known as gruit and used as hops are now used. Some beers today, such as Fraoch' by the Scottish Heather Ales company and Cervoise Lancelot by the French Brasserie-Lancelot company, use plants other than hops for flavouring. Hops contain several characteristics that brewers desire in beer. Hops contribute a bitterness that balances the sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale. Hops contribute floral, citrus, and herbal aromas and flavours to beer. Hops have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms and aids in "head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops is a preservative. Yeast is the microorganism that is responsible for fermentation in beer. Yeast metabolises the sugars extracted from grains, which produce alcohol and carbon dioxide, and thereby turns wort into beer. In addition to fermenting the beer, yeast influences the character and flavour. The dominant types of yeast used to make beer are top-fermenting Saccharomyces cerevisiae and bottom-fermenting Saccharomyces pastorianus. Brettanomyces ferments lambics, and Torulaspora delbrueckii ferments Bavarian weissbier. Before the role of yeast in fermentation was understood, fermentation involved wild or airborne yeasts. A few styles, such as lambics, rely on this method today, but most modern fermentation adds pure yeast cultures. Some brewers add one or more clarifying agents or finings to beer, which typically precipitate (collect as a solid) out of the beer along with protein solids and are found only in trace amounts in the finished product. This process makes the beer appear bright and clean, rather than the cloudy appearance of ethnic and older styles of beer, such as wheat beers. Examples of clarifying agents include isinglass, obtained from the swimbladders of fish; Irish moss, a seaweed; kappa carrageenan, from the seaweed Kappaphycus cottonii; Polyclar (artificial); and gelatin. If a beer is marked "suitable for vegans", it is clarified either with seaweed or with artificial agents. Brewing industry The history of breweries in the 21st century has included larger breweries absorbing smaller breweries in order to ensure economy of scale. In 2002, South African Breweries bought the North American Miller Brewing Company to found SABMiller, becoming the second-largest brewery after North American Anheuser-Busch. In 2004, the Belgian Interbrew was the third-largest brewery by volume, and the Brazilian AmBev was the fifth-largest. They merged into InBev, becoming the largest brewery. In 2007, SABMiller surpassed InBev and Anheuser-Busch when it acquired Royal Grolsch, the brewer of Dutch premium beer brand Grolsch. In 2008, when InBev (the second-largest) bought Anheuser-Busch (the third-largest), the new Anheuser-Busch InBev company became again the largest brewer in the world. , according to the market research firm Technavio, AB InBev remains the largest brewing company in the world, with Heineken second, CR Snow third, Carlsberg fourth, and Molson Coors fifth. A microbrewery, or craft brewery, produces a limited amount of beer. The maximum amount of beer a brewery can produce and still be classed as a 'microbrewery' varies by region and by authority; in the US, it is a year. A brewpub is a type of microbrewery that incorporates a pub or other drinking establishment. The highest density of breweries in the world, most of them microbreweries, exists in Franconia, Germany, especially in the district of Upper Franconia, which has about 200 breweries. The Benedictine Weihenstephan brewery in Bavaria, Germany, can trace its roots to the year 768, as a document from that year refers to a hop garden in the area paying a tithe to the monastery. The brewery was licensed by the City of Freising in 1040 and is therefore the oldest working brewery in the world. Varieties While there are many types of beer brewed, the basics of brewing beer are shared across national and cultural boundaries. The traditional European brewing regions—Germany, Belgium, England and the Czech Republic—have local varieties of beer. English writer Michael Jackson, in his 1977 book The World Guide To Beer, categorised beers from around the world in local style groups suggested by local customs and names. Fred Eckhardt furthered Jackson's work in The Essentials of Beer Style in 1989. Top-fermented beers Top-fermented beers are most commonly produced with Saccharomyces cerevisiae, a top-fermenting yeast which clumps and rises to the surface, typically between . At these temperatures, yeast produces significant amounts of esters and other secondary flavour and aroma products, and the result is often a beer with slightly "fruity" compounds resembling apple, pear, pineapple, banana, plum, or prune, among others. After the introduction of hops into England from Flanders in the 15th century, "ale" referred to an unhopped fermented drink, "beer" being used to describe a brew with an infusion of hops. Real ale is the term coined by the Campaign for Real Ale (CAMRA) in 1973 for "beer brewed from traditional ingredients, matured by secondary fermentation in the container from which it is dispensed, and served without the use of extraneous carbon dioxide". It is applied to bottle conditioned and cask conditioned beers. Pale ale is a beer which uses a top-fermenting yeast and predominantly pale malt. It is one of the world's major beer styles. The India pale ale (IPA) variety is especially popular. Mild ale has a predominantly malty palate. It is usually dark coloured with an abv of 3% to 3.6%, although there are lighter hued milds as well as stronger examples reaching 6% abv and higher. Wheat beer is brewed with a large proportion of wheat although it often also contains a significant proportion of malted barley. Wheat beers are usually top-fermented. The flavour of wheat beers varies considerably, depending upon the specific style. Stout is a dark beer made using roasted barley, and typically brewed with slow fermenting yeast. There are a number of variations including dry stout (such as Guinness), sweet stout, and Imperial (or Russian) stout. Like stout, porter is a dark beer, but made with malted barley. The name "porter" was first used in 1721 to describe a dark brown beer popular with the street and river porters of London. This same beer later also became known as stout, though the word stout had been used as early as 1677. The history and development of stout and porter are intertwined, though now distinguished by whether the barley has been malted or not. Bottom-fermented beers Lager is cool fermented beer. Pale lagers are the most commonly consumed beers in the world. Many are of the "pilsner" type. The name "lager" comes from the German "lagern" for "to store", as brewers around Bavaria stored beer in cool cellars and caves during the warm summer months. These brewers noticed that the beers continued to ferment, and to also clear of sediment, when stored in cool conditions. Lager yeast is a cool bottom-fermenting yeast (Saccharomyces pastorianus) and typically undergoes primary fermentation at (the fermentation phase), and then is given a long secondary fermentation at (the lagering phase). During the secondary stage, the lager clears and mellows. The cooler conditions also inhibit the natural production of esters and other byproducts, resulting in a "cleaner"-tasting beer. With improved modern yeast strains, most lager breweries use only short periods of cold storage, typically 1–3 weeks. Other types of beer Lambic, a beer of Belgium, is naturally fermented using wild yeasts, rather than cultivated. Many of these are not strains of brewer's yeast (Saccharomyces cerevisiae) and may have significant differences in aroma and sourness. Yeast varieties such as Brettanomyces bruxellensis and Brettanomyces lambicus are common in lambics. In addition, other organisms such as Lactobacillus bacteria produce acids which contribute to the sourness. Measurement Beer is measured and assessed by colour, by strength and by bitterness. The perceived bitterness is measured by the International Bitterness Units scale (IBU), defined in co-operation between the American Society of Brewing Chemists and the European Brewery Convention. The international scale was a development of the European Bitterness Units scale, often abbreviated as EBU, and the bitterness values should be identical. Colour Beer colour is determined by the malt. The most common colour is a pale amber produced from using pale malts. Pale lager and pale ale are terms used for beers made from malt dried with the fuel coke. Coke was first used for roasting malt in 1642, but it was not until around 1703 that the term pale ale was used. In terms of sales volume, most of today's beer is based on the pale lager brewed in 1842 in the town of Pilsen in the present-day Czech Republic. The modern pale lager is light in colour with a noticeable carbonation (fizzy bubbles) and a typical alcohol by volume content of around 5%. The Pilsner Urquell, Bitburger, and Heineken brands of beer are typical examples of pale lager, as are the American brands Budweiser, Coors, and Miller. Dark beers are usually brewed from a pale malt or lager malt base with a small proportion of darker malt added to achieve the desired shade. Other colourants—such as caramel—are also widely used to darken beers. Very dark beers, such as stout, use dark or patent malts that have been roasted longer. Some have roasted unmalted barley. Strength Beer ranges from less than 3% alcohol by volume (abv) to around 14% abv, though this strength can be increased to around 20% by re-pitching with champagne yeast, and to 55% abv by the freeze-distilling process. The alcohol content of beer varies by local practice or beer style. The pale lagers that most consumers are familiar with fall in the range of 4–6%, with a typical abv of 5%. The customary strength of British ales is quite low, with many session beers being around 4% abv. In Belgium, some beers, such as table beer are of such low alcohol content (1%–4%) that they are served instead of soft drinks in some schools. The weakest beers are dealcoholized beers, which typically have less than 0.05% alcohol (also called "near beer") and light beers, which usually have 4% alcohol. The alcohol in beer comes primarily from the metabolism of sugars that are produced during fermentation. The quantity of fermentable sugars in the wort and the variety of yeast used to ferment the wort are the primary factors that determine the amount of alcohol in the final beer. Additional fermentable sugars are sometimes added to increase alcohol content, and enzymes are often added to the wort for certain styles of beer (primarily "light" beers) to convert more complex carbohydrates (starches) to fermentable sugars. Alcohol is a by-product of yeast metabolism and is toxic to the yeast in higher concentrations; typical brewing yeast cannot survive at alcohol concentrations above 12% by volume. Low temperatures and too little fermentation time decreases the effectiveness of yeasts and consequently decreases the alcohol content. The strength of beers has climbed during the later years of the 20th century. Vetter 33, a 10.5% abv (33 degrees Plato, hence Vetter "33") doppelbock, was listed in the 1994 Guinness Book of World Records as the strongest beer at that time, though Samichlaus, by the Swiss brewer Hürlimann, had also been listed by the Guinness Book of World Records as the strongest at 14% abv. Since then, some brewers have used champagne yeasts to increase the alcohol content of their beers. Samuel Adams reached 20% abv with Millennium, and then surpassed that amount to 25.6% abv with Utopias. The strongest beer brewed in Britain was Baz's Super Brew by Parish Brewery, a 23% abv beer. In September 2011, the Scottish brewery BrewDog produced Ghost Deer, which, at 28%, they claim to be the world's strongest beer produced by fermentation alone. The product claimed to be the strongest beer made is Schorschbräu's 2011 Schorschbock 57 with 57,5%. It was preceded by The End of History, a 55% Belgian ale, made by BrewDog in 2010. The same company had previously made Sink The Bismarck!, a 41% abv IPA, and Tactical Nuclear Penguin, a 32% abv Imperial stout. Each of these beers are made using the eisbock method of fractional freezing, in which a strong ale is partially frozen and the ice is repeatedly removed, until the desired strength is reached, a process that may class the product as spirits rather than beer. The German brewery Schorschbräu's Schorschbock, a 31% abv eisbock, and Hair of the Dog's Dave, a 29% abv barley wine made in 1994, used the same fractional freezing method. A 60% abv blend of beer with whiskey was jokingly claimed as the strongest beer by a Dutch brewery in July 2010. Serving Draught Draught (also spelled "draft") beer from a pressurised keg using a lever-style dispenser and a spout is the most common method of dispensing in bars around the world. A metal keg is pressurised with carbon dioxide (CO2) gas which drives the beer to the dispensing tap or faucet. Some beers may be served with a nitrogen/carbon dioxide mixture. Nitrogen produces fine bubbles, resulting in a dense head and a creamy mouthfeel. Some types of beer can also be found in smaller, disposable kegs called beer balls. In traditional pubs, the pull levers for major beer brands may include the beer's logo and trademark. In the 1980s, Guinness introduced the beer widget, a nitrogen-pressurised ball inside a can which creates a dense, tight head, similar to beer served from a nitrogen system. The words draft and draught can be used as marketing terms to describe canned or bottled beers containing a beer widget, or which are cold-filtered rather than pasteurised. Cask-conditioned ales (or cask ales) are unfiltered and unpasteurised beers. These beers are termed "real ale" by the CAMRA organisation. Typically, when a cask arrives in a pub, it is placed horizontally on a frame called a "stillage" which is designed to hold it steady and at the right angle, and then allowed to cool to cellar temperature (typically between ), before being tapped and vented—a tap is driven through a (usually rubber) bung at the bottom of one end, and a hard spile or other implement is used to open a hole in the side of the cask, which is now uppermost. The act of stillaging and then venting a beer in this manner typically disturbs all the sediment, so it must be left for a suitable period to "drop" (clear) again, as well as to fully condition—this period can take anywhere from several hours to several days. At this point the beer is ready to sell, either being pulled through a beer line with a hand pump, or simply being "gravity-fed" directly into the glass. Draught beer's environmental impact can be 68% lower than bottled beer due to packaging differences. A life cycle study of one beer brand, including grain production, brewing, bottling, distribution and waste management, shows that the CO2 emissions from a 6-pack of micro-brew beer is about 3 kilograms (6.6 pounds). The loss of natural habitat potential from the 6-pack of micro-brew beer is estimated to be 2.5 square metres (26 square feet). Downstream emissions from distribution, retail, storage and disposal of waste can be over 45% of a bottled micro-brew beer's CO2 emissions. Where legal, the use of a refillable jug, reusable bottle or other reusable containers to transport draught beer from a store or a bar, rather than buying pre-bottled beer, can reduce the environmental impact of beer consumption. Packaging Most beers are cleared of yeast by filtering when packaged in bottles and cans. However, bottle conditioned beers retain some yeast—either by being unfiltered, or by being filtered and then reseeded with fresh yeast. It is usually recommended that the beer be poured slowly, leaving any yeast sediment at the bottom of the bottle. However, some drinkers prefer to pour in the yeast; this practice is customary with wheat beers. Typically, when serving a hefeweizen wheat beer, 90% of the contents are poured, and the remainder is swirled to suspend the sediment before pouring it into the glass. Alternatively, the bottle may be inverted prior to opening. Glass bottles are always used for bottle conditioned beers. Many beers are sold in cans, though there is considerable variation in the proportion between different countries. In Sweden in 2001, 63.9% of beer was sold in cans. People either drink from the can or pour the beer into a glass. A technology developed by Crown Holdings for the 2010 FIFA World Cup is the 'full aperture' can, so named because the entire lid is removed during the opening process, turning the can into a drinking cup. Cans protect the beer from light (thereby preventing "skunked" beer) and have a seal less prone to leaking over time than bottles. Cans were initially viewed as a technological breakthrough for maintaining the quality of a beer, then became commonly associated with less expensive, mass-produced beers, even though the quality of storage in cans is much like bottles. Plastic (PET) bottles are used by some breweries. Temperature The temperature of a beer has an influence on a drinker's experience; warmer temperatures reveal the range of flavours in a beer but cooler temperatures are more refreshing. Most drinkers prefer pale lager to be served chilled, a low- or medium-strength pale ale to be served cool, while a strong barley wine or imperial stout to be served at room temperature. Beer writer Michael Jackson proposed a five-level scale for serving temperatures: well chilled () for "light" beers (pale lagers); chilled () for Berliner Weisse and other wheat beers; lightly chilled () for all dark lagers, altbier and German wheat beers; cellar temperature () for regular British ale, stout and most Belgian specialities; and room temperature () for strong dark ales (especially trappist beer) and barley wine. Drinking chilled beer began with the development of artificial refrigeration and by the 1870s, was spread in those countries that concentrated on brewing pale lager. Chilling beer makes it more refreshing, though below 15.5 °C (60 °F) the chilling starts to reduce taste awareness and reduces it significantly below . Beer served unchilled—either cool or at room temperature—reveal more of their flavours. Cask Marque, a non-profit UK beer organisation, has set a temperature standard range of 12°–14 °C (53°–57 °F) for cask ales to be served. Vessels Beer is consumed out of a variety of vessels, such as a glass, a beer stein, a mug, a pewter tankard, a beer bottle or a can; or at music festivals and some bars and nightclubs, from a plastic cup. The shape of the glass from which beer is consumed can influence the perception of the beer and can define and accent the character of the style. Breweries offer branded glassware intended only for their own beers as a marketing promotion, as this increases sales of their product. The pouring process has an influence on a beer's presentation. The rate of flow from the tap or other serving vessel, tilt of the glass, and position of the pour (in the centre or down the side) into the glass all influence the result, such as the size and longevity of the head, lacing (the pattern left by the head as it moves down the glass as the beer is drunk), and the release of carbonation. A beer tower is a beer dispensing device, usually found in bars and pubs, that consists of a cylinder attached to a beer cooling device at the bottom. Beer is dispensed from the beer tower into a drinking vessel. Health effects A 2016 systematic review and meta-analysis found that moderate ethanol consumption brought no mortality benefit compared with lifetime abstention from ethanol consumption. Some studies have concluded that drinking small quantities of alcohol (less than one drink in women and two in men, per day) is associated with a decreased risk of heart disease, stroke, diabetes mellitus, and early death. Some of these studies combined former ethanol drinkers and lifelong abstainers into a single group of nondrinkers, which hides the health benefits of lifelong abstention from ethanol. The long-term health effects of continuous, moderate or heavy alcohol consumption include the risk of developing alcoholism and alcoholic liver disease. Alcoholism, also known as "alcohol use disorder", is a broad term for any drinking of alcohol that results in problems. It was previously divided into two types: alcohol abuse and alcohol dependence. In a medical context, alcoholism is said to exist when two or more of the following conditions are present: a person drinks large amounts over a long time period, has difficulty cutting down, acquiring and drinking alcohol takes up a great deal of time, alcohol is strongly desired, usage results in not fulfilling responsibilities, usage results in social problems, usage results in health problems, usage results in risky situations, withdrawal occurs when stopping, and alcohol tolerance has occurred with use. Alcoholism reduces a person's life expectancy by around ten years and alcohol use is the third leading cause of early death in the United States. No professional medical association recommends that people who are nondrinkers should start drinking alcoholic beverages. In the United States, a total of 3.3 million deaths per year (5.9% of all deaths) are believed to be due to alcohol. It is considered that overeating and lack of muscle tone is the main cause of a beer belly, rather than beer consumption. A 2004 study, however, found a link between binge drinking and a beer belly. But with most overconsumption, it is more a problem of improper exercise and overconsumption of carbohydrates than the product itself. Several diet books quote beer as having an undesirably high glycemic index of 110, the same as maltose; however, the maltose in beer undergoes metabolism by yeast during fermentation so that beer consists mostly of water, hop oils and only trace amounts of sugars, including maltose. Nutritional information Beers vary in their nutritional content. The ingredients used to make beer, including the yeast, provide a rich source of nutrients; therefore beer may contain nutrients including magnesium, selenium, potassium, phosphorus, biotin, chromium and B vitamins. Beer is sometimes referred to as "liquid bread", though beer is not a meal in itself. Society and culture In many societies, beer is the most popular alcoholic drink. Various social traditions and activities are associated with beer drinking, such as playing cards, darts, or other pub games; attending beer festivals; engaging in zythology (the study of beer); visiting a series of pubs in one evening; visiting breweries; beer-oriented tourism; or rating beer. Drinking games, such as beer pong, are also popular. A relatively new profession is that of the beer sommelier, who informs restaurant patrons about beers and food pairings. Beer is considered to be a social lubricant in many societies and is consumed in countries all over the world. There are breweries in Middle Eastern countries such as Syria, and in some African countries. Sales of beer are four times those of wine, which is the second most popular alcoholic drink. A study published in the Neuropsychopharmacology journal in 2013 revealed the finding that the flavour of beer alone could provoke dopamine activity in the brain of the male participants, who wanted to drink more as a result. The 49 men in the study were subject to positron emission tomography scans, while a computer-controlled device sprayed minute amounts of beer, water and a sports drink onto their tongues. Compared with the taste of the sports drink, the taste of beer significantly increased the participants desire to drink. Test results indicated that the flavour of the beer triggered a dopamine release, even though alcohol content in the spray was insufficient for the purpose of becoming intoxicated. Some breweries have developed beers to pair with food. Wine writer Malcolm Gluck disputed the need to pair beer with food, while beer writers Roger Protz and Melissa Cole contested that claim. Related drinks Around the world, there are many traditional and ancient starch-based drinks classed as beer. In Africa, there are various ethnic beers made from sorghum or millet, such as Oshikundu in Namibia and Tella in Ethiopia. Kyrgyzstan also has a beer made from millet; it is a low alcohol, somewhat porridge-like drink called "Bozo". Bhutan, Nepal, Tibet and Sikkim also use millet in Chhaang, a popular semi-fermented rice/millet drink in the eastern Himalayas. Further east in China are found Huangjiu and Choujiu—traditional rice-based drinks related to beer. The Andes in South America has Chicha, made from germinated maize (corn); while the indigenous peoples in Brazil have Cauim, a traditional drink made since pre-Columbian times by chewing manioc so that an enzyme (amylase) present in human saliva can break down the starch into fermentable sugars; this is similar to Masato in Peru. Some beers which are made from bread, which is linked to the earliest forms of beer, are Sahti in Finland, Kvass in Russia and Ukraine, and Bouza in Sudan. 4000 years ago fermented bread was used in Mesopotamia. Food waste activists got inspired by these ancient recipes and use leftover bread to replace a third of the malted barley that would otherwise be used for brewing their craft ale. Chemistry Beer contains the phenolic acids 4-hydroxyphenylacetic acid, vanillic acid, caffeic acid, syringic acid, p-coumaric acid, ferulic acid, and sinapic acid. Alkaline hydrolysis experiments show that most of the phenolic acids are present as bound forms and only a small portion can be detected as free compounds. Hops, and beer made with it, contain 8-prenylnaringenin which is a potent phytoestrogen. Hop also contains myrcene, humulene, xanthohumol, isoxanthohumol, myrcenol, linalool, tannins, and resin. The alcohol 2M2B is a component of hops brewing. Barley, in the form of malt, brings the condensed tannins prodelphinidins B3, B9 and C2 into beer. Tryptophol, tyrosol, and phenylethanol are aromatic higher alcohols found in beer as secondary products of alcoholic fermentation (products also known as congeners) by Saccharomyces cerevisiae.

Bit

The bit is the most basic unit of information in computing and digital communications. The name is a portmanteau of binary digit. The bit represents a logical state with one of two possible values. These values are most commonly represented as either , but other representations such as true/false, yes/no, on/off, or +/− are also widely used. The relation between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. It may be physically implemented with a two-state device. A contiguous group of binary digits is commonly called a bit string, a bit vector, or a single-dimensional (or multi-dimensional) bit array. A group of eight bits is called one byte, but historically the size of the byte is not strictly defined. Frequently, half, full, double and quadruple words consist of a number of bytes which is a low power of two. A string of four bits is a nibble. In information theory, one bit is the information entropy of a random binary variable that is 0 or 1 with equal probability, or the information that is gained when the value of such a variable becomes known. As a unit of information, the bit is also known as a shannon, named after Claude E. Shannon. The symbol for the binary digit is either "bit", per the IEC 80000-13:2008 standard, or the lowercase character "b", per the IEEE 1541-2002 standard. Use of the latter may create confusion with the capital "B" which is the international standard symbol for the byte. History The encoding of data by discrete bits was used in the punched cards invented by Basile Bouchon and Jean-Baptiste Falcon (1732), developed by Joseph Marie Jacquard (1804), and later adopted by Semyon Korsakov, Charles Babbage, Herman Hollerith, and early computer manufacturers like IBM. A variant of that idea was the perforated paper tape. In all those systems, the medium (card or tape) conceptually carried an array of hole positions; each position could be either punched through or not, thus carrying one bit of information. The encoding of text by bits was also used in Morse code (1844) and early digital communications machines such as teletypes and stock ticker machines (1870). Ralph Hartley suggested the use of a logarithmic measure of information in 1928. Claude E. Shannon first used the word "bit" in his seminal 1948 paper "A Mathematical Theory of Communication". He attributed its origin to John W. Tukey, who had written a Bell Labs memo on 9 January 1947 in which he contracted "binary information digit" to simply "bit". Vannevar Bush had written in 1936 of "bits of information" that could be stored on the punched cards used in the mechanical computers of that time. The first programmable computer, built by Konrad Zuse, used binary notation for numbers. Physical representation A bit can be stored by a digital device or other physical system that exists in either of two possible distinct states. These may be the two stable states of a flip-flop, two positions of an electrical switch, two distinct voltage or current levels allowed by a circuit, two distinct levels of light intensity, two directions of magnetization or polarization, the orientation of reversible double stranded DNA, etc. Bits can be implemented in several forms. In most modern computing devices, a bit is usually represented by an electrical voltage or current pulse, or by the electrical state of a flip-flop circuit. For devices using positive logic, a digit value of (or a logical value of true) is represented by a more positive voltage relative to the representation of . Different logic families require different voltages, and variations are allowed to account for component aging and noise immunity. For example, in transistor–transistor logic (TTL) and compatible circuits, digit values and at the output of a device are represented by no higher than 0.4 volts and no lower than 2.6 volts, respectively; while TTL inputs are specified to recognize 0.8 volts or below as and 2.2 volts or above as . Transmission and processing Bits are transmitted one at a time in serial transmission, and by a multiple number of bits in parallel transmission. A bitwise operation optionally processes bits one at a time. Data transfer rates are usually measured in decimal SI multiples of the unit bit per second (bit/s), such as kbit/s. Storage In the earliest non-electronic information processing devices, such as Jacquard's loom or Babbage's Analytical Engine, a bit was often stored as the position of a mechanical lever or gear, or the presence or absence of a hole at a specific point of a paper card or tape. The first electrical devices for discrete logic (such as elevator and traffic light control circuits, telephone switches, and Konrad Zuse's computer) represented bits as the states of electrical relays which could be either "open" or "closed". When relays were replaced by vacuum tubes, starting in the 1940s, computer builders experimented with a variety of storage methods, such as pressure pulses traveling down a mercury delay line, charges stored on the inside surface of a cathode-ray tube, or opaque spots printed on glass discs by photolithographic techniques. In the 1950s and 1960s, these methods were largely supplanted by magnetic storage devices such as magnetic-core memory, magnetic tapes, drums, and disks, where a bit was represented by the polarity of magnetization of a certain area of a ferromagnetic film, or by a change in polarity from one direction to the other. The same principle was later used in the magnetic bubble memory developed in the 1980s, and is still found in various magnetic strip items such as metro tickets and some credit cards. In modern semiconductor memory, such as dynamic random-access memory, the two values of a bit may be represented by two levels of electric charge stored in a capacitor. In certain types of programmable logic arrays and read-only memory, a bit may be represented by the presence or absence of a conducting path at a certain point of a circuit. In optical discs, a bit is encoded as the presence or absence of a microscopic pit on a reflective surface. In one-dimensional bar codes, bits are encoded as the thickness of alternating black and white lines. Unit and symbol The bit is not defined in the International System of Units (SI). However, the International Electrotechnical Commission issued standard IEC 60027, which specifies that the symbol for binary digit should be 'bit', and this should be used in all multiples, such as 'kbit', for kilobit. However, the lower-case letter 'b' is widely used as well and was recommended by the IEEE 1541 Standard (2002). In contrast, the upper case letter 'B' is the standard and customary symbol for byte. Multiple bits Multiple bits may be expressed and represented in several ways. For convenience of representing commonly reoccurring groups of bits in information technology, several units of information have traditionally been used. The most common is the unit byte, coined by Werner Buchholz in June 1956, which historically was used to represent the group of bits used to encode a single character of text (until UTF-8 multibyte encoding took over) in a computer and for this reason it was used as the basic addressable element in many computer architectures. The trend in hardware design converged on the most common implementation of using eight bits per byte, as it is widely used today. However, because of the ambiguity of relying on the underlying hardware design, the unit octet was defined to explicitly denote a sequence of eight bits. Computers usually manipulate bits in groups of a fixed size, conventionally named "words". Like the byte, the number of bits in a word also varies with the hardware design, and is typically between 8 and 80 bits, or even more in some specialized computers. In the 21st century, retail personal or server computers have a word size of 32 or 64 bits. The International System of Units defines a series of decimal prefixes for multiples of standardized units which are commonly also used with the bit and the byte. The prefixes kilo (103) through yotta (1024) increment by multiples of one thousand, and the corresponding units are the kilobit (kbit) through the yottabit (Ybit). Information capacity and information compression When the information capacity of a storage system or a communication channel is presented in bits or bits per second, this often refers to binary digits, which is a computer hardware capacity to store binary data ( or , up or down, current or not, etc.). Information capacity of a storage system is only an upper bound to the quantity of information stored therein. If the two possible values of one bit of storage are not equally likely, that bit of storage contains less than one bit of information. If the value is completely predictable, then the reading of that value provides no information at all (zero entropic bits, because no resolution of uncertainty occurs and therefore no information is available). If a computer file that uses n bits of storage contains only m < n bits of information, then that information can in principle be encoded in about m bits, at least on the average. This principle is the basis of data compression technology. Using an analogy, the hardware binary digits refer to the amount of storage space available (like the number of buckets available to store things), and the information content the filling, which comes in different levels of granularity (fine or coarse, that is, compressed or uncompressed information). When the granularity is finer—when information is more compressed—the same bucket can hold more. For example, it is estimated that the combined technological capacity of the world to store information provides 1,300 exabytes of hardware digits. However, when this storage space is filled and the corresponding content is optimally compressed, this only represents 295 exabytes of information. When optimally compressed, the resulting carrying capacity approaches Shannon information or information entropy. Bit-based computing Certain bitwise computer processor instructions (such as bit set) operate at the level of manipulating bits rather than manipulating data interpreted as an aggregate of bits. In the 1980s, when bitmapped computer displays became popular, some computers provided specialized bit block transfer instructions to set or copy the bits that corresponded to a given rectangular area on the screen. In most computers and programming languages, when a bit within a group of bits, such as a byte or word, is referred to, it is usually specified by a number from 0 upwards corresponding to its position within the byte or word. However, 0 can refer to either the most or least significant bit depending on the context. Other information units Similar to torque and energy in physics; information-theoretic information and data storage size have the same dimensionality of units of measurement, but there is in general no meaning to adding, subtracting or otherwise combining the units mathematically, although one may act as a bound on the other. Units of information used in information theory include the shannon (Sh), the natural unit of information (nat) and the hartley (Hart). One shannon is the maximum amount of information needed to specify the state of one bit of storage. These are related by 1 Sh ≈ 0.693 nat ≈ 0.301 Hart. Some authors also define a binit as an arbitrary information unit equivalent to some fixed but unspecified number of bits.

Byte

The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words of 12, 18, 24, 30, 36, 48, or 60 bits, corresponding to 2, 3, 4, 5, 6, 8, or 10 six-bit bytes. In this era, bit groupings in the instruction stream were often referred to as syllables or slab, before the term byte became common. The modern de facto standard of eight bits, as documented in ISO/IEC 2382-1:1993, is a convenient power of two permitting the binary-encoded values 0 through 255 for one byte, as 2 to the power of 8 is 256. The international standard IEC 80000-13 codified this common meaning. Many types of applications use information representable in eight or fewer bits and processor designers commonly optimize for this usage. The popularity of major commercial computing architectures has aided in the ubiquitous acceptance of the 8-bit byte. Modern architectures typically use 32- or 64-bit words, built of four or eight bytes, respectively. The unit symbol for the byte was designated as the upper-case letter B by the International Electrotechnical Commission (IEC) and Institute of Electrical and Electronics Engineers (IEEE). Internationally, the unit octet, symbol o, explicitly defines a sequence of eight bits, eliminating the potential ambiguity of the term "byte". Etymology and history The term byte was coined by Werner Buchholz in June 1956, during the early design phase for the IBM Stretch computer, which had addressing to the bit and variable field length (VFL) instructions with a byte size encoded in the instruction. It is a deliberate respelling of bite to avoid accidental mutation to bit. Another origin of byte for bit groups smaller than a computer's word size, and in particular groups of four bits, is on record by Louis G. Dooley, who claimed he coined the term while working with Jules Schwartz and Dick Beeler on an air defense system called SAGE at MIT Lincoln Laboratory in 1956 or 1957, which was jointly developed by Rand, MIT, and IBM. Later on, Schwartz's language JOVIAL actually used the term, but the author recalled vaguely that it was derived from AN/FSQ-31. Early computers used a variety of four-bit binary-coded decimal (BCD) representations and the six-bit codes for printable graphic patterns common in the U.S. Army (FIELDATA) and Navy. These representations included alphanumeric characters and special graphical symbols. These sets were expanded in 1963 to seven bits of coding, called the American Standard Code for Information Interchange (ASCII) as the Federal Information Processing Standard, which replaced the incompatible teleprinter codes in use by different branches of the U.S. government and universities during the 1960s. ASCII included the distinction of upper- and lowercase alphabets and a set of control characters to facilitate the transmission of written language as well as printing device functions, such as page advance and line feed, and the physical or logical control of data flow over the transmission media. During the early 1960s, while also active in ASCII standardization, IBM simultaneously introduced in its product line of System/360 the eight-bit Extended Binary Coded Decimal Interchange Code (EBCDIC), an expansion of their six-bit binary-coded decimal (BCDIC) representations used in earlier card punches. The prominence of the System/360 led to the ubiquitous adoption of the eight-bit storage size, while in detail the EBCDIC and ASCII encoding schemes are different. In the early 1960s, AT&T introduced digital telephony on long-distance trunk lines. These used the eight-bit μ-law encoding. This large investment promised to reduce transmission costs for eight-bit data. In Volume 1 of The Art of Computer Programming (first published in 1968), Donald Knuth uses byte in his hypothetical MIX computer to denote a unit which "contains an unspecified amount of information ... capable of holding at least 64 distinct values ... at most 100 distinct values. On a binary computer a byte must therefore be composed of six bits". He notes that "Since 1975 or so, the word byte has come to mean a sequence of precisely eight binary digits...When we speak of bytes in connection with MIX we shall confine ourselves to the former sense of the word, harking back to the days when bytes were not yet standardized." The development of eight-bit microprocessors in the 1970s popularized this storage size. Microprocessors such as the Intel 8008, the direct predecessor of the 8080 and the 8086, used in early personal computers, could also perform a small number of operations on the four-bit pairs in a byte, such as the decimal-add-adjust (DAA) instruction. A four-bit quantity is often called a nibble, also nybble, which is conveniently represented by a single hexadecimal digit. The term octet is used to unambiguously specify a size of eight bits. It is used extensively in protocol definitions. Historically, the term octad or octade was used to denote eight bits as well at least in Western Europe; however, this usage is no longer common. The exact origin of the term is unclear, but it can be found in British, Dutch, and German sources of the 1960s and 1970s, and throughout the documentation of Philips mainframe computers. Unit symbol The unit symbol for the byte is specified in IEC 80000-13, IEEE 1541 and the Metric Interchange Format as the upper-case character B. In the International System of Quantities (ISQ), B is also the symbol of the bel, a unit of logarithmic power ratio named after Alexander Graham Bell, creating a conflict with the IEC specification. However, little danger of confusion exists, because the bel is a rarely used unit. It is used primarily in its decadic fraction, the decibel (dB), for signal strength and sound pressure level measurements, while a unit for one-tenth of a byte, the decibyte, and other fractions, are only used in derived units, such as transmission rates. The lowercase letter o for octet is defined as the symbol for octet in IEC 80000-13 and is commonly used in languages such as French and Romanian, and is also combined with metric prefixes for multiples, for example ko and Mo. Multiple-byte units More than one system exists to define unit multiples based on the byte. Some systems are based on powers of 10, following the International System of Units (SI), which defines for example the prefix kilo as 1000 (103); other systems are based on powers of 2. Nomenclature for these systems has confusion. Systems based on powers of 10 use standard SI prefixes (kilo, mega, giga, ...) and their corresponding symbols (k, M, G, ...). Systems based on powers of 2, however, might use binary prefixes (kibi, mebi, gibi, ...) and their corresponding symbols (Ki, Mi, Gi, ...) or they might use the prefixes K, M, and G, creating ambiguity when the prefixes M or G are used. While the difference between the decimal and binary interpretations is relatively small for the kilobyte (about 2% smaller than the kibibyte), the systems deviate increasingly as units grow larger (the relative deviation grows by 2.4% for each three orders of magnitude). For example, a power-of-10-based terabyte is about 9% smaller than power-of-2-based teribyte. Units based on powers of 10 Definition of prefixes using powers of 10—in which 1 kilobyte (symbol kB) is defined to equal 1,000 bytes—is recommended by the International Electrotechnical Commission (IEC). The IEC standard defines eight such multiples, up to 1 yottabyte (YB), equal to 10008 bytes. The additional prefixes ronna- for 10009 and quetta- for 100010 were adopted by the International Bureau of Weights and Measures (BIPM) in 2022. This definition is most commonly used for data-rate units in computer networks, internal bus, hard drive and flash media transfer speeds, and for the capacities of most storage media, particularly hard drives, flash-based storage, and DVDs. Operating systems that use this definition include macOS, iOS, Ubuntu, and Debian. It is also consistent with the other uses of the SI prefixes in computing, such as CPU clock speeds or measures of performance. Units based on powers of 2 A system of units based on powers of 2 in which 1 kibibyte (KiB) is equal to 1,024 (i.e., 210) bytes is defined by international standard IEC 80000-13 and is supported by national and international standards bodies (BIPM, IEC, NIST). The IEC standard defines eight such multiples, up to 1 yobibyte (YiB), equal to 10248 bytes. The natural binary counterparts to ronna- and quetta- were given in a consultation paper of the International Committee for Weights and Measures' Consultative Committee for Units (CCU) as robi- (Ri, 10249) and quebi- (Qi, 102410), but have not yet been adopted by the IEC and ISO. An alternate system of nomenclature for the same units (referred to here as the customary convention), in which 1 kilobyte (KB) is equal to 1,024 bytes, 1 megabyte (MB) is equal to 10242 bytes and 1 gigabyte (GB) is equal to 10243 bytes is mentioned by a 1990s JEDEC standard. Only the first three multiples (up to GB) are mentioned by the JEDEC standard, which makes no mention of TB and larger. The customary convention is used by the Microsoft Windows operating system and random-access memory capacity, such as main memory and CPU cache size, and in marketing and billing by telecommunication companies, such as Vodafone, AT&T, Orange and Telstra. For storage capacity, the customary convention was used by macOS and iOS through Mac OS X 10.6 Snow Leopard and iOS 10, after which they switched to units based on powers of 10. Parochial units Various computer vendors have coined terms for data of various sizes, sometimes with different sizes for the same term even within a single vendor. These terms include double word, half word, long word, quad word, slab, superword and syllable. There are also informal terms. e.g., half byte and nybble for 4 bits, octal K for . History of the conflicting definitions Contemporary computer memory has a binary architecture making a definition of memory units based on powers of 2 most practical. The use of the metric prefix kilo for binary multiples arose as a convenience, because 1,024 is approximately 1,000. This definition was popular in early decades of personal computing, with products like the Tandon 5-inch DD floppy format (holding 368,640 bytes) being advertised as "360 KB", following the 1,024-byte convention. It was not universal, however. The Shugart SA-400 5-inch floppy disk held 109,375 bytes unformatted, and was advertised as "110 Kbyte", using the 1000 convention. Likewise, the 8-inch DEC RX01 floppy (1975) held 256,256 bytes formatted, and was advertised as "256k". Other disks were advertised using a mixture of the two definitions: notably, -inch HD disks advertised as "1.44 MB" in fact have a capacity of 1,440 KiB, the equivalent of 1.47 MB or 1.41 MiB. In 1995, the International Union of Pure and Applied Chemistry's (IUPAC) Interdivisional Committee on Nomenclature and Symbols attempted to resolve this ambiguity by proposing a set of binary prefixes for the powers of 1024, including kibi (kilobinary), mebi (megabinary), and gibi (gigabinary). In December 1998, the IEC addressed such multiple usages and definitions by adopting the IUPAC's proposed prefixes (kibi, mebi, gibi, etc.) to unambiguously denote powers of 1024. Thus one kibibyte (1 KiB) is 10241  bytes = 1024 bytes, one mebibyte (1 MiB) is 10242  bytes = bytes, and so on. In 1999, Donald Knuth suggested calling the kibibyte a "large kilobyte" (KKB). Modern standard definitions The IEC adopted the IUPAC proposal and published the standard in January 1999. The IEC prefixes are part of the International System of Quantities. The IEC further specified that the kilobyte should only be used to refer to 1,000 bytes. Lawsuits over definition Lawsuits arising from alleged consumer confusion over the binary and decimal definitions of multiples of the byte have generally ended in favor of the manufacturers, with courts holding that the legal definition of gigabyte or GB is 1 GB = 1,000,000,000 (109) bytes (the decimal definition), rather than the binary definition (230, i.e., 1,073,741,824). Specifically, the United States District Court for the Northern District of California held that "the U.S. Congress has deemed the decimal definition of gigabyte to be the 'preferred' one for the purposes of 'U.S. trade and commerce' [...] The California Legislature has likewise adopted the decimal system for all 'transactions in this state. Earlier lawsuits had ended in settlement with no court ruling on the question, such as a lawsuit against drive manufacturer Western Digital. Western Digital settled the challenge and added explicit disclaimers to products that the usable capacity may differ from the advertised capacity. Seagate was sued on similar grounds and also settled. Practical examples Common uses Many programming languages define the data type byte. The C and C++ programming languages define byte as an "addressable unit of data storage large enough to hold any member of the basic character set of the execution environment" (clause 3.6 of the C standard). The C standard requires that the integral data type unsigned char must hold at least 256 different values, and is represented by at least eight bits (clause 5.2.4.2.1). Various implementations of C and C++ reserve 8, 9, 16, 32, or 36 bits for the storage of a byte. In addition, the C and C++ standards require that there are no gaps between two bytes. This means every bit in memory is part of a byte. Java's primitive data type byte is defined as eight bits. It is a signed data type, holding values from −128 to 127. .NET programming languages, such as C#, define byte as an unsigned type, and the sbyte as a signed data type, holding values from 0 to 255, and −128 to 127, respectively. In data transmission systems, the byte is used as a contiguous sequence of bits in a serial data stream, representing the smallest distinguished unit of data. A transmission unit might additionally include start bits, stop bits, and parity bits, and thus its size may vary from seven to twelve bits to contain a single seven-bit ASCII code.

Boron nitride

Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN. It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products. The cubic (zincblende aka sphalerite structure) variety analogous to diamond is called c-BN; it is softer than diamond, but its thermal and chemical stability is superior. The rare wurtzite BN modification is similar to lonsdaleite but slightly softer than the cubic form. Because of excellent thermal and chemical stability, boron nitride ceramics are used in high-temperature equipment and metal casting. Boron nitride has potential use in nanotechnology. Structure Boron nitride exists in multiple forms that differ in the arrangement of the boron and nitrogen atoms, giving rise to varying bulk properties of the material. Amorphous form (a-BN) The amorphous form of boron nitride (a-BN) is non-crystalline, lacking any long-distance regularity in the arrangement of its atoms. It is analogous to amorphous carbon. All other forms of boron nitride are crystalline. Hexagonal form (h-BN) The most stable crystalline form is the hexagonal one, also called h-BN, α-BN, g-BN, and graphitic boron nitride. Hexagonal boron nitride (point group = D6h; space group = P63/mmc) has a layered structure similar to graphite. Within each layer, boron and nitrogen atoms are bound by strong covalent bonds, whereas the layers are held together by weak van der Waals forces. The interlayer "registry" of these sheets differs, however, from the pattern seen for graphite, because the atoms are eclipsed, with boron atoms lying over and above nitrogen atoms. This registry reflects the local polarity of the B–N bonds, as well as interlayer N-donor/B-acceptor characteristics. Likewise, many metastable forms consisting of differently stacked polytypes exist. Therefore, h-BN and graphite are very close neighbors, and the material can accommodate carbon as a substituent element to form BNCs. BC6N hybrids have been synthesized, where carbon substitutes for some B and N atoms. Hexagonal boron nitride monolayer is analogous to graphene, having a honeycomb lattice structure of nearly the same dimensions. Unlike graphene, which is black and an electrical conductor, h-BN monolayer is white and an insulator. It has been proposed for use as an atomic flat insulating substrate or a tunneling dielectric barrier in 2D electronics. . Cubic form (c-BN) Cubic boron nitride has a crystal structure analogous to that of diamond. Consistent with diamond being less stable than graphite, the cubic form is less stable than the hexagonal form, but the conversion rate between the two is negligible at room temperature, as it is for diamond. The cubic form has the sphalerite crystal structure (space group = F3m), the same as that of diamond (with ordered B and N atoms), and is also called β-BN or c-BN. Wurtzite form (w-BN) The wurtzite form of boron nitride (w-BN; point group = C6v; space group = P63mc) has the same structure as lonsdaleite, a rare hexagonal polymorph of carbon. As in the cubic form, the boron and nitrogen atoms are grouped into tetrahedra. In the wurtzite form, the boron and nitrogen atoms are grouped into 6-membered rings. In the cubic form all rings are in the chair configuration, whereas in w-BN the rings between 'layers' are in boat configuration. Earlier optimistic reports predicted that the wurtzite form was very strong, and was estimated by a simulation as potentially having a strength 18% stronger than that of diamond. Since only small amounts of the mineral exist in nature, this has not yet been experimentally verified. Its hardness is 46 GPa, slightly harder than commercial borides but softer than the cubic form of boron nitride. Properties Physical The partly ionic structure of BN layers in h-BN reduces covalency and electrical conductivity, whereas the interlayer interaction increases resulting in higher hardness of h-BN relative to graphite. The reduced electron-delocalization in hexagonal-BN is also indicated by its absence of color and a large band gap. Very different bonding – strong covalent within the basal planes (planes where boron and nitrogen atoms are covalently bonded) and weak between them – causes high anisotropy of most properties of h-BN. For example, the hardness, electrical and thermal conductivity are much higher within the planes than perpendicular to them. On the contrary, the properties of c-BN and w-BN are more homogeneous and isotropic. Those materials are extremely hard, with the hardness of bulk c-BN being slightly smaller and w-BN even higher than that of diamond. Polycrystalline c-BN with grain sizes on the order of 10 nm is also reported to have Vickers hardness comparable or higher than diamond. Because of much better stability to heat and transition metals, c-BN surpasses diamond in mechanical applications, such as machining steel. The thermal conductivity of BN is among the highest of all electric insulators (see table). Boron nitride can be doped p-type with beryllium and n-type with boron, sulfur, silicon or if co-doped with carbon and nitrogen. Both hexagonal and cubic BN are wide-gap semiconductors with a band-gap energy corresponding to the UV region. If voltage is applied to h-BN or c-BN, then it emits UV light in the range 215–250 nm and therefore can potentially be used as light-emitting diodes (LEDs) or lasers. Little is known on melting behavior of boron nitride. It sublimates at 2973 °C at normal pressure releasing nitrogen gas and boron, but melts at elevated pressure. Thermal stability Hexagonal and cubic BN (and probably w-BN) show remarkable chemical and thermal stabilities. For example, h-BN is stable to decomposition at temperatures up to 1000 °C in air, 1400 °C in vacuum, and 2800 °C in an inert atmosphere. The reactivity of h-BN and c-BN is relatively similar, and the data for c-BN are summarized in the table below. Thermal stability of c-BN can be summarized as follows: In air or oxygen: protective layer prevents further oxidation to ~1300 °C; no conversion to hexagonal form at 1400 °C. In nitrogen: some conversion to h-BN at 1525 °C after 12 h. In vacuum (): conversion to h-BN at 1550–1600 °C. Chemical stability Boron nitride is insoluble in the usual acids, but is soluble in alkaline molten salts and nitrides, such as LiOH, KOH, NaOH-, , , , , or , which are therefore used to etch BN. Thermal conductivity The theoretical thermal conductivity of hexagonal boron nitride nanoribbons (BNNRs) can approach 1700–2000 W/(m⋅K), which has the same order of magnitude as the experimental measured value for graphene, and can be comparable to the theoretical calculations for graphene nanoribbons. Moreover, the thermal transport in the BNNRs is anisotropic. The thermal conductivity of zigzag-edged BNNRs is about 20% larger than that of armchair-edged nanoribbons at room temperature. Natural occurrence In 2009, a naturally occurring boron nitride mineral in the cubic form (c-BN) was reported in Tibet, and the name qingsongite proposed. The substance was found in dispersed micron-sized inclusions in chromium-rich rocks. In 2013, the International Mineralogical Association affirmed the mineral and the name. Synthesis Preparation and reactivity of hexagonal BN Boron nitride is produced synthetically. Hexagonal boron nitride is obtained by the reacting boron trioxide () or boric acid () with ammonia () or urea () in a nitrogen atmosphere: (T = 900 °C) (T = 900 °C) (T > 1000 °C) (T > 1500 °C) The resulting disordered (amorphous) boron nitride contains 92–95% BN and 5–8% . The remaining can be evaporated in a second step at temperatures in order to achieve BN concentration >98%. Such annealing also crystallizes BN, the size of the crystallites increasing with the annealing temperature. h-BN parts can be fabricated inexpensively by hot-pressing with subsequent machining. The parts are made from boron nitride powders adding boron oxide for better compressibility. Thin films of boron nitride can be obtained by chemical vapor deposition from boron trichloride and nitrogen precursors. ZYP Coatings also has developed boron nitride coatings that may be painted on a surface. Combustion of boron powder in nitrogen plasma at 5500 °C yields ultrafine boron nitride used for lubricants and toners. Boron nitride reacts with iodine fluoride in trichlorofluoromethane at −30 °C to produce an extremely sensitive contact explosive, , in low yield. Boron nitride reacts with nitrides of lithium, alkaline earth metals and lanthanides to form nitridoborate compounds. For example: Intercalation of hexagonal BN Similar to graphite, various molecules, such as or alkali metals, can be intercalated into hexagonal boron nitride, that is inserted between its layers. Both experiment and theory suggest the intercalation is much more difficult for BN than for graphite. Preparation of cubic BN Synthesis of c-BN uses same methods as that of diamond: cubic boron nitride is produced by treating hexagonal boron nitride at high pressure and temperature, much as synthetic diamond is produced from graphite. Direct conversion of hexagonal boron nitride to the cubic form has been observed at pressures between 5 and 18 GPa and temperatures between 1730 and 3230 °C, that is similar parameters as for direct graphite-diamond conversion. The addition of a small amount of boron oxide can lower the required pressure to 4–7 GPa and temperature to 1500 °C. As in diamond synthesis, to further reduce the conversion pressures and temperatures, a catalyst is added, such as lithium, potassium, or magnesium, their nitrides, their fluoronitrides, water with ammonium compounds, or hydrazine. Other industrial synthesis methods, again borrowed from diamond growth, use crystal growth in a temperature gradient, or explosive shock wave. The shock wave method is used to produce material called heterodiamond, a superhard compound of boron, carbon, and nitrogen. Low-pressure deposition of thin films of cubic boron nitride is possible. As in diamond growth, the major problem is to suppress the growth of hexagonal phases (h-BN or graphite, respectively). Whereas in diamond growth this is achieved by adding hydrogen gas, boron trifluoride is used for c-BN. Ion beam deposition, plasma-enhanced chemical vapor deposition, pulsed laser deposition, reactive sputtering, and other physical vapor deposition methods are used as well. Preparation of wurtzite BN Wurtzite BN can be obtained via static high-pressure or dynamic shock methods. The limits of its stability are not well defined. Both c-BN and w-BN are formed by compressing h-BN, but formation of w-BN occurs at much lower temperatures close to 1700 °C. Production statistics Whereas the production and consumption figures for the raw materials used for BN synthesis, namely boric acid and boron trioxide, are well known (see boron), the corresponding numbers for the boron nitride are not listed in statistical reports. An estimate for the 1999 world production is 300 to 350 metric tons. The major producers and consumers of BN are located in the United States, Japan, China and Germany. In 2000, prices varied from about $75–120/kg for standard industrial-quality h-BN and were about up to $200–400/kg for high purity BN grades. Applications Hexagonal BN Hexagonal BN (h-BN) is the most widely used polymorph. It is a good lubricant at both low and high temperatures (up to 900 °C, even in an oxidizing atmosphere). h-BN lubricant is particularly useful when the electrical conductivity or chemical reactivity of graphite (alternative lubricant) would be problematic. In internal combustion engines, where graphite could be oxidized and turn into carbon sludge, h-BN with its superior thermal stability can be added to engine lubricants. As with all nano-particle suspensions, Brownian-motion settlement is a problem. Settlement can clog engine oil filters, which limits solid lubricant applications in a combustion engine to automotive racing, where engine re-building is common. Since carbon has appreciable solubility in certain alloys (such as steels), which may lead to degradation of properties, BN is often superior for high temperature and/or high pressure applications. Another advantage of h-BN over graphite is that its lubricity does not require water or gas molecules trapped between the layers. Therefore, h-BN lubricants can be used in vacuum, such as space applications. The lubricating properties of fine-grained h-BN are used in cosmetics, paints, dental cements, and pencil leads. Hexagonal BN was first used in cosmetics around 1940 in Japan. Because of its high price, h-BN was abandoned for this application. Its use was revitalized in the late 1990s with the optimization h-BN production processes, and currently h-BN is used by nearly all leading producers of cosmetic products for foundations, make-up, eye shadows, blushers, kohl pencils, lipsticks and other skincare products. Because of its excellent thermal and chemical stability, boron nitride ceramics and coatings are used high-temperature equipment. h-BN can be included in ceramics, alloys, resins, plastics, rubbers, and other materials, giving them self-lubricating properties. Such materials are suitable for construction of e.g. bearings and in steelmaking. Recently, h-BN coatings have been used in 3d printing  applications. Plastics filled with BN have less thermal expansion as well as higher thermal conductivity and electrical resistivity. Due to its excellent dielectric and thermal properties, BN is used in electronics as a substrate for semiconductors, microwave-transparent windows, as a heat conductive yet electrically insulating filler in thermal pastes and as a structural material for seals. Many quantum devices use multilayer h-BN as a substrate material. It can also be used as a dielectric in resistive random access memories. Hexagonal BN is used in xerographic process and laser printers as a charge leakage barrier layer of the photo drum. In the automotive industry, h-BN mixed with a binder (boron oxide) is used for sealing oxygen sensors, which provide feedback for adjusting fuel flow. The binder utilizes the unique temperature stability and insulating properties of h-BN. Parts can be made by hot pressing from four commercial grades of h-BN. Grade HBN contains a boron oxide binder; it is usable up to 550–850 °C in oxidizing atmosphere and up to 1600 °C in vacuum, but due to the boron oxide content is sensitive to water. Grade HBR uses a calcium borate binder and is usable at 1600 °C. Grades HBC and HBT contain no binder and can be used up to 3000 °C. Boron nitride nanosheets (h-BN) can be deposited by catalytic decomposition of borazine at a temperature ~1100 °C in a chemical vapor deposition setup, over areas up to about 10 cm2. Owing to their hexagonal atomic structure, small lattice mismatch with graphene (~2%), and high uniformity they are used as substrates for graphene-based devices. BN nanosheets are also excellent proton conductors. Their high proton transport rate, combined with the high electrical resistance, may lead to applications in fuel cells and water electrolysis. h-BN has been used since the mid-2000s as a bullet and bore lubricant in precision target rifle applications as an alternative to molybdenum disulfide coating, commonly referred to as "moly". It is claimed to increase effective barrel life, increase intervals between bore cleaning and decrease the deviation in point of impact between clean bore first shots and subsequent shots. h-BN is used as a release agent in molten metal and glass applications. For example, ZYP Coatings developed and currently produces a line of paintable h-BN coatings that are used by manufacturers of molten aluminium, non-ferrous metal, and glass. Because h-BN is nonwetting and lubricious to these molten materials, the coated surface (i.e. mold or crucible) does not stick to the material. Cubic BN Cubic boron nitride (CBN or c-BN) is widely used as an abrasive. Its usefulness arises from its insolubility in iron, nickel, and related alloys at high temperatures, whereas diamond is soluble in these metals. Polycrystalline c-BN (PCBN) abrasives are therefore used for machining steel, whereas diamond abrasives are preferred for aluminum alloys, ceramics, and stone. When in contact with oxygen at high temperatures, BN forms a passivation layer of boron oxide. Boron nitride binds well with metals due to formation of interlayers of metal borides or nitrides. Materials with cubic boron nitride crystals are often used in the tool bits of cutting tools. For grinding applications, softer binders such as resin, porous ceramics and soft metals are used. Ceramic binders can be used as well. Commercial products are known under names "Borazon" (by Hyperion Materials & Technologies), and "Elbor" or "Cubonite" (by Russian vendors). Contrary to diamond, large c-BN pellets can be produced in a simple process (called sintering) of annealing c-BN powders in nitrogen flow at temperatures slightly below the BN decomposition temperature. This ability of c-BN and h-BN powders to fuse allows cheap production of large BN parts. Similar to diamond, the combination in c-BN of highest thermal conductivity and electrical resistivity is ideal for heat spreaders. As cubic boron nitride consists of light atoms and is very robust chemically and mechanically, it is one of the popular materials for X-ray membranes: low mass results in small X-ray absorption, and good mechanical properties allow usage of thin membranes, further reducing the absorption. Amorphous BN Layers of amorphous boron nitride (a-BN) are used in some semiconductor devices, e.g. MOSFETs. They can be prepared by chemical decomposition of trichloroborazine with caesium, or by thermal chemical vapor deposition methods. Thermal CVD can be also used for deposition of h-BN layers, or at high temperatures, c-BN. Other forms of boron nitride Atomically thin boron nitride Hexagonal boron nitride can be exfoliated to mono or few atomic layer sheets. Due to its analogous structure to that of graphene, atomically thin boron nitride is sometimes called white graphene. Mechanical properties Atomically thin boron nitride is one of the strongest electrically insulating materials. Monolayer boron nitride has an average Young's modulus of 0.865TPa and fracture strength of 70.5GPa, and in contrast to graphene, whose strength decreases dramatically with increased thickness, few-layer boron nitride sheets have a strength similar to that of monolayer boron nitride. Thermal conductivity Atomically thin boron nitride has one of the highest thermal conductivity coefficients (851 W/mK at room temperature) among semiconductors and electrical insulators, and its thermal conductivity increases with reduced thickness due to less intra-layer coupling. Thermal stability The air stability of graphene shows a clear thickness dependence: monolayer graphene is reactive to oxygen at 250 °C, strongly doped at 300 °C, and etched at 450 °C; in contrast, bulk graphite is not oxidized until 800 °C. Atomically thin boron nitride has much better oxidation resistance than graphene. Monolayer boron nitride is not oxidized till 700 °C and can sustain up to 850 °C in air; bilayer and trilayer boron nitride nanosheets have slightly higher oxidation starting temperatures. The excellent thermal stability, high impermeability to gas and liquid, and electrical insulation make atomically thin boron nitride potential coating materials for preventing surface oxidation and corrosion of metals and other two-dimensional (2D) materials, such as black phosphorus. Better surface adsorption Atomically thin boron nitride has been found to have better surface adsorption capabilities than bulk hexagonal boron nitride. According to theoretical and experimental studies, atomically thin boron nitride as an adsorbent experiences conformational changes upon surface adsorption of molecules, increasing adsorption energy and efficiency. The synergic effect of the atomic thickness, high flexibility, stronger surface adsorption capability, electrical insulation, impermeability, high thermal and chemical stability of BN nanosheets can increase the Raman sensitivity by up to two orders, and in the meantime attain long-term stability and reusability not readily achievable by other materials. Dielectric properties Atomically thin hexagonal boron nitride is an excellent dielectric substrate for graphene, molybdenum disulfide (), and many other 2D material-based electronic and photonic devices. As shown by electric force microscopy (EFM) studies, the electric field screening in atomically thin boron nitride shows a weak dependence on thickness, which is in line with the smooth decay of electric field inside few-layer boron nitride revealed by the first-principles calculations. Raman characteristics Raman spectroscopy has been a useful tool to study a variety of 2D materials, and the Raman signature of high-quality atomically thin boron nitride was first reported by Gorbachev et al. in 2011. and Li et al. However, the two reported Raman results of monolayer boron nitride did not agree with each other. Cai et al., therefore, conducted systematic experimental and theoretical studies to reveal the intrinsic Raman spectrum of atomically thin boron nitride. It reveals that atomically thin boron nitride without interaction with a substrate has a G band frequency similar to that of bulk hexagonal boron nitride, but strain induced by the substrate can cause Raman shifts. Nevertheless, the Raman intensity of G band of atomically thin boron nitride can be used to estimate layer thickness and sample quality. Boron nitride nanomesh Boron nitride nanomesh is a nanostructured two-dimensional material. It consists of a single BN layer, which forms by self-assembly a highly regular mesh after high-temperature exposure of a clean rhodium or ruthenium surface to borazine under ultra-high vacuum. The nanomesh looks like an assembly of hexagonal pores. The distance between two pore centers is 3.2 nm and the pore diameter is ~2 nm. Other terms for this material are boronitrene or white graphene. The boron nitride nanomesh is air-stable and compatible with some liquids. up to temperatures of 800 °C. Boron nitride nanotubes Boron nitride tubules were first made in 1989 by Shore and Dolan This work was patented in 1989 and published in 1989 thesis (Dolan) and then 1993 Science. The 1989 work was also the first preparation of amorphous BN by B-trichloroborazine and cesium metal. Boron nitride nanotubes were predicted in 1994 and experimentally discovered in 1995. They can be imagined as a rolled up sheet of h-boron nitride. Structurally, it is a close analog of the carbon nanotube, namely a long cylinder with diameter of several to hundred nanometers and length of many micrometers, except carbon atoms are alternately substituted by nitrogen and boron atoms. However, the properties of BN nanotubes are very different: whereas carbon nanotubes can be metallic or semiconducting depending on the rolling direction and radius, a BN nanotube is an electrical insulator with a bandgap of ~5.5 eV, basically independent of tube chirality and morphology. In addition, a layered BN structure is much more thermally and chemically stable than a graphitic carbon structure. Boron nitride aerogel Boron nitride aerogel is an aerogel made of highly porous BN. It typically consists of a mixture of deformed BN nanotubes and nanosheets. It can have a density as low as 0.6 mg/cm3 and a specific surface area as high as 1050 m2/g, and therefore has potential applications as an absorbent, catalyst support and gas storage medium. BN aerogels are highly hydrophobic and can absorb up to 160 times their weight in oil. They are resistant to oxidation in air at temperatures up to 1200 °C, and hence can be reused after the absorbed oil is burned out by flame. BN aerogels can be prepared by template-assisted chemical vapor deposition using borazine as the feed gas. Composites containing BN Addition of boron nitride to silicon nitride ceramics improves the thermal shock resistance of the resulting material. For the same purpose, BN is added also to silicon nitride-alumina and titanium nitride-alumina ceramics. Other materials being reinforced with BN include alumina and zirconia, borosilicate glasses, glass ceramics, enamels, and composite ceramics with titanium boride-boron nitride, titanium boride-aluminium nitride-boron nitride, and silicon carbide-boron nitride composition. Health issues Boron nitride (along with , NbN, and BNC) is generally considered to be non-toxic and does not exhibit chemical activity in biological systems. Due to its excellent safety profile and lubricious properties, boron nitride finds widespread use in various applications, including cosmetics and food processing equipment.

Beryllium

Beryllium is a chemical element with the symbol Be and atomic number 4. It is a steel-gray, strong, lightweight and brittle alkaline earth metal. It is a divalent element that occurs naturally only in combination with other elements to form minerals. Gemstones high in beryllium include beryl (aquamarine, emerald, red beryl) and chrysoberyl. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars, beryllium is depleted as it is fused into heavier elements. Beryllium constitutes about 0.0004 percent by mass of Earth's crust. The world's annual beryllium production of 220 tons is usually manufactured by extraction from the mineral beryl, a difficult process because beryllium bonds strongly to oxygen. In structural applications, the combination of high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of water) make beryllium metal a desirable aerospace material for aircraft components, missiles, spacecraft, and satellites. Because of its low density and atomic mass, beryllium is relatively transparent to X-rays and other forms of ionizing radiation; therefore, it is the most common window material for X-ray equipment and components of particle detectors. When added as an alloying element to aluminium, copper (notably the alloy beryllium copper), iron, or nickel, beryllium improves many physical properties. For example, tools and components made of beryllium copper alloys are strong and hard and do not create sparks when they strike a steel surface. In air, the surface of beryllium oxidizes readily at room temperature to form a passivation layer 1–10 nm thick that protects it from further oxidation and corrosion. The metal oxidizes in bulk (beyond the passivation layer) when heated above , and burns brilliantly when heated to about . The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis. Berylliosis causes pneumonia and other associated respiratory illness. Characteristics Physical properties Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. It has exceptional stiffness (Young's modulus 287 GPa) and a melting point of 1287 °C. The modulus of elasticity of beryllium is approximately 35% greater than that of steel. The combination of this modulus and a relatively low density results in an unusually fast sound conduction speed in beryllium – about 12.9 km/s at ambient conditions. Other significant properties are high specific heat () and thermal conductivity (), which make beryllium the metal with the best heat dissipation characteristics per unit weight. In combination with the relatively low coefficient of linear thermal expansion (11.4×10−6 K−1), these characteristics result in a unique stability under conditions of thermal loading. Nuclear properties Naturally occurring beryllium, save for slight contamination by the cosmogenic radioisotopes, is isotopically pure beryllium-9, which has a nuclear spin of . Beryllium has a large scattering cross section for high-energy neutrons, about 6 barns for energies above approximately 10 keV. Therefore, it works as a neutron reflector and neutron moderator, effectively slowing the neutrons to the thermal energy range of below 0.03 eV, where the total cross section is at least an order of magnitude lower; the exact value strongly depends on the purity and size of the crystallites in the material. The single primordial beryllium isotope 9Be also undergoes a (n,2n) neutron reaction with neutron energies over about 1.9 MeV, to produce 8Be, which almost immediately breaks into two alpha particles. Thus, for high-energy neutrons, beryllium is a neutron multiplier, releasing more neutrons than it absorbs. This nuclear reaction is: + n → 2 + 2 n Neutrons are liberated when beryllium nuclei are struck by energetic alpha particles producing the nuclear reaction + → + n where is an alpha particle and is a carbon-12 nucleus. Beryllium also releases neutrons under bombardment by gamma rays. Thus, natural beryllium bombarded either by alphas or gammas from a suitable radioisotope is a key component of most radioisotope-powered nuclear reaction neutron sources for the laboratory production of free neutrons. Small amounts of tritium are liberated when nuclei absorb low energy neutrons in the three-step nuclear reaction + n → + ,    → + β−,    + n → + has a half-life of only 0.8 seconds, β− is an electron, and has a high neutron absorption cross section. Tritium is a radioisotope of concern in nuclear reactor waste streams. Optical properties As a metal, beryllium is transparent or translucent to most wavelengths of X-rays and gamma rays, making it useful for the output windows of X-ray tubes and other such apparatus. Isotopes and nucleosynthesis Both stable and unstable isotopes of beryllium are created in stars, but the radioisotopes do not last long. It is believed that most of the stable beryllium in the universe was originally created in the interstellar medium when cosmic rays induced fission in heavier elements found in interstellar gas and dust. Primordial beryllium contains only one stable isotope, 9Be, and therefore beryllium is a monoisotopic and mononuclidic element. Radioactive cosmogenic 10Be is produced in the atmosphere of the Earth by the cosmic ray spallation of oxygen. 10Be accumulates at the soil surface, where its relatively long half-life (1.36 million years) permits a long residence time before decaying to boron-10. Thus, 10Be and its daughter products are used to examine natural soil erosion, soil formation and the development of lateritic soils, and as a proxy for measurement of the variations in solar activity and the age of ice cores. The production of 10Be is inversely proportional to solar activity, because increased solar wind during periods of high solar activity decreases the flux of galactic cosmic rays that reach the Earth. Nuclear explosions also form 10Be by the reaction of fast neutrons with 13C in the carbon dioxide in air. This is one of the indicators of past activity at nuclear weapon test sites. The isotope 7Be (half-life 53 days) is also cosmogenic, and shows an atmospheric abundance linked to sunspots, much like 10Be. 8Be has a very short half-life of about 8 s that contributes to its significant cosmological role, as elements heavier than beryllium could not have been produced by nuclear fusion in the Big Bang. This is due to the lack of sufficient time during the Big Bang's nucleosynthesis phase to produce carbon by the fusion of 4He nuclei and the very low concentrations of available beryllium-8. British astronomer Sir Fred Hoyle first showed that the energy levels of 8Be and 12C allow carbon production by the so-called triple-alpha process in helium-fueled stars where more nucleosynthesis time is available. This process allows carbon to be produced in stars, but not in the Big Bang. Star-created carbon (the basis of carbon-based life) is thus a component in the elements in the gas and dust ejected by AGB stars and supernovae (see also Big Bang nucleosynthesis), as well as the creation of all other elements with atomic numbers larger than that of carbon. The 2s electrons of beryllium may contribute to chemical bonding. Therefore, when 7Be decays by L-electron capture, it does so by taking electrons from its atomic orbitals that may be participating in bonding. This makes its decay rate dependent to a measurable degree upon its chemical surroundings – a rare occurrence in nuclear decay. The shortest-lived known isotope of beryllium is 16Be, which decays through neutron emission with a half-life of . The exotic isotopes 11Be and 14Be are known to exhibit a nuclear halo. This phenomenon can be understood as the nuclei of 11Be and 14Be have, respectively, 1 and 4 neutrons orbiting substantially outside the classical Fermi 'waterdrop' model of the nucleus. Occurrence The Sun has a concentration of 0.1 parts per billion (ppb) of beryllium. Beryllium has a concentration of 2 to 6 parts per million (ppm) in the Earth's crust. It is most concentrated in the soils, 6 ppm. Trace amounts of 9Be are found in the Earth's atmosphere. The concentration of beryllium in sea water is 0.2–0.6 parts per trillion. In stream water, however, beryllium is more abundant with a concentration of 0.1 ppb. Beryllium is found in over 100 minerals, but most are uncommon to rare. The more common beryllium containing minerals include: bertrandite (Be4Si2O7(OH)2), beryl (Al2Be3Si6O18), chrysoberyl (Al2BeO4) and phenakite (Be2SiO4). Precious forms of beryl are aquamarine, red beryl and emerald. The green color in gem-quality forms of beryl comes from varying amounts of chromium (about 2% for emerald). The two main ores of beryllium, beryl and bertrandite, are found in Argentina, Brazil, India, Madagascar, Russia and the United States. Total world reserves of beryllium ore are greater than 400,000 tonnes. Production The extraction of beryllium from its compounds is a difficult process due to its high affinity for oxygen at elevated temperatures, and its ability to reduce water when its oxide film is removed. Currently the United States, China and Kazakhstan are the only three countries involved in the industrial-scale extraction of beryllium. Kazakhstan produces beryllium from a concentrate stockpiled before the breakup of the Soviet Union around 1991. This resource had become nearly depleted by mid-2010s. Production of beryllium in Russia was halted in 1997, and is planned to be resumed in the 2020s. Beryllium is most commonly extracted from the mineral beryl, which is either sintered using an extraction agent or melted into a soluble mixture. The sintering process involves mixing beryl with sodium fluorosilicate and soda at to form sodium fluoroberyllate, aluminium oxide and silicon dioxide. Beryllium hydroxide is precipitated from a solution of sodium fluoroberyllate and sodium hydroxide in water. Extraction of beryllium using the melt method involves grinding beryl into a powder and heating it to . The melt is quickly cooled with water and then reheated in concentrated sulfuric acid, mostly yielding beryllium sulfate and aluminium sulfate. Aqueous ammonia is then used to remove the aluminium and sulfur, leaving beryllium hydroxide. Beryllium hydroxide created using either the sinter or melt method is then converted into beryllium fluoride or beryllium chloride. To form the fluoride, aqueous ammonium hydrogen fluoride is added to beryllium hydroxide to yield a precipitate of ammonium tetrafluoroberyllate, which is heated to to form beryllium fluoride. Heating the fluoride to with magnesium forms finely divided beryllium, and additional heating to creates the compact metal. Heating beryllium hydroxide forms the oxide, which becomes beryllium chloride when combined with carbon and chlorine. Electrolysis of molten beryllium chloride is then used to obtain the metal. Chemical properties A beryllium atom has the electronic configuration [He] 2s2. The predominant oxidation state of beryllium is +2; the beryllium atom has lost both of its valence electrons. Lower oxidation states complexes of beryllium are exceedingly rare. For example, bis(carbene) compounds proposed to contain beryllium in the 0- and +1-oxidation state have been reported, although these claims have proved controversial. A stable complex with a Be-Be bond, which formally features beryllium in the +1 oxidation state, has been described. Beryllium's chemical behavior is largely a result of its small atomic and ionic radii. It thus has very high ionization potentials and strong polarization while bonded to other atoms, which is why all of its compounds are covalent. Its chemistry has similarities to that of aluminium, an example of a diagonal relationship. At room temperature, the surface of beryllium forms a 1−10 nm-thick oxide passivation layer that prevents further reactions with air, except for gradual thickening of the oxide up to about 25 nm. When heated above about 500 °C, oxidation into the bulk metal progresses along grain boundaries. Once the metal is ignited in air by heating above the oxide melting point around 2500 °C, beryllium burns brilliantly, forming a mixture of beryllium oxide and beryllium nitride. Beryllium dissolves readily in non-oxidizing acids, such as HCl and diluted H2SO4, but not in nitric acid or water as this forms the oxide. This behavior is similar to that of aluminium metal. Beryllium also dissolves in alkali solutions. Binary compounds of beryllium(II) are polymeric in the solid state. BeF2 has a silica-like structure with corner-shared BeF4 tetrahedra. BeCl2 and BeBr2 have chain structures with edge-shared tetrahedra. Beryllium oxide, BeO, is a white refractory solid, which has the wurtzite crystal structure and a thermal conductivity as high as some metals. BeO is amphoteric. Beryllium sulfide, selenide and telluride are known, all having the zincblende structure. Beryllium nitride, Be3N2 is a high-melting-point compound which is readily hydrolyzed. Beryllium azide, BeN6 is known and beryllium phosphide, Be3P2 has a similar structure to Be3N2. A number of beryllium borides are known, such as Be5B, Be4B, Be2B, BeB2, BeB6 and BeB12. Beryllium carbide, Be2C, is a refractory brick-red compound that reacts with water to give methane. No beryllium silicide has been identified. The halides BeX2 (X = F, Cl, Br, I) have a linear monomeric molecular structure in the gas phase. Complexes of the halides are formed with one or more ligands donating at total of two pairs of electrons. Such compounds obey the octet rule. Other 4-coordinate complexes such as the aqua-ion [Be(H2O)4]2+ also obey the octet rule. Aqueous solutions Solutions of beryllium salts, such as beryllium sulfate and beryllium nitrate, are acidic because of hydrolysis of the [Be(H2O)4]2+ ion. The concentration of the first hydrolysis product, [Be(H2O)3(OH)]+, is less than 1% of the beryllium concentration. The most stable hydrolysis product is the trimeric ion [Be3(OH)3(H2O)6]3+. Beryllium hydroxide, Be(OH)2, is insoluble in water at pH 5 or more. Consequently, beryllium compounds are generally insoluble at biological pH. Because of this, inhalation of beryllium metal dust by people leads to the development of the fatal condition of berylliosis. Be(OH)2 dissolves in strongly alkaline solutions. Beryllium(II) forms few complexes with monodentate ligands because the water molecules in the aquo-ion, [Be(H2O)4]2+ are bound very strongly to the beryllium ion. Notable exceptions are the series of water-soluble complexes with the fluoride ion: [Be(H2O)4]^2+{} + \mathit{n}\,F^- <=> Be[(H2O)_{2\!-\mathit{n}}F_\mathit{n}]^{2\!-\mathit{n}}{} + \mathit{n}\,H2O Beryllium(II) forms many complexes with bidentate ligands containing oxygen-donor atoms. The species [Be3O(H2PO4)6]2- is notable for having a 3-coordinate oxide ion at its center. Basic beryllium acetate, Be4O(OAc)6, has an oxide ion surrounded by a tetrahedron of beryllium atoms. With organic ligands, such as the malonate ion, the acid deprotonates when forming the complex. The donor atoms are two oxygens. H2A + [Be(H2O)4]^2+ <=> [BeA(H2O)2] + 2H+ + 2H2O H2A + [BeA(H2O)2] <=> [BeA2]^2- + 2H+ + 2H2O Formation of a complex is in competition with the metal ion-hydrolysis reaction and mixed complexes with both the anion and the hydroxide ion are also formed. For example, derivatives of the cyclic trimer are known, with a bidentate ligand replacing one or more pairs of water molecules. Aliphatic hydroxycarboxylic acids such as glycollic acid form rather weak, monodentate complexes in solution, in which the hydroxyl group remains intact. In the solid state, the hydroxyl group may deprotonate: a hexamer, Na_4[Be_6(OCH_2(O)O)_6] , was isolated long ago. Aromatic hydroxy ligands (i.e. phenols) form relatively strong complexes. For example, log K1 and log K2 values of 12.2 and 9.3 have been reported for complexes with tiron. Beryllium has generally a rather poor affinity for ammine ligands. Ligands such as EDTA behave as dicarboxylic acids. There are many early reports of complexes with amino acids, but unfortunately they are not reliable as the concomitant hydrolysis reactions were not understood at the time of publication. Values for log β of ca. 6 to 7 have been reported. The degree of formation is small because of competition with hydrolysis reactions. Organic chemistry Organoberyllium chemistry is limited to academic research due to the cost and toxicity of beryllium, beryllium derivatives and reagents required for the introduction of beryllium, such as beryllium chloride. Organometallic beryllium compounds are known to be highly reactive Examples of known organoberyllium compounds are dineopentylberyllium, beryllocene (Cp2Be), diallylberyllium (by exchange reaction of diethyl beryllium with triallyl boron), bis(1,3-trimethylsilylallyl)beryllium, Be(mes)2, and (beryllium(I) complex) diberyllocene. Ligands can also be aryls and alkynyls. History The mineral beryl, which contains beryllium, has been used at least since the Ptolemaic dynasty of Egypt. In the first century CE, Roman naturalist Pliny the Elder mentioned in his encyclopedia Natural History that beryl and emerald ("smaragdus") were similar. The Papyrus Graecus Holmiensis, written in the third or fourth century CE, contains notes on how to prepare artificial emerald and beryl. Early analyses of emeralds and beryls by Martin Heinrich Klaproth, Torbern Olof Bergman, Franz Karl Achard, and Johann Jakob Bindheim always yielded similar elements, leading to the mistaken conclusion that both substances are aluminium silicates. Mineralogist René Just Haüy discovered that both crystals are geometrically identical, and he asked chemist Louis-Nicolas Vauquelin for a chemical analysis. In a 1798 paper read before the Institut de France, Vauquelin reported that he found a new "earth" by dissolving aluminium hydroxide from emerald and beryl in an additional alkali. The editors of the journal Annales de Chimie et de Physique named the new earth "glucine" for the sweet taste of some of its compounds. Klaproth preferred the name "beryllina" due to the fact that yttria also formed sweet salts. The name "beryllium" was first used by Wöhler in 1828. Friedrich Wöhler and Antoine Bussy independently isolated beryllium in 1828 by the chemical reaction of metallic potassium with beryllium chloride, as follows: BeCl2 + 2 K → 2 KCl + Be Using an alcohol lamp, Wöhler heated alternating layers of beryllium chloride and potassium in a wired-shut platinum crucible. The above reaction immediately took place and caused the crucible to become white hot. Upon cooling and washing the resulting gray-black powder he saw that it was made of fine particles with a dark metallic luster. The highly reactive potassium had been produced by the electrolysis of its compounds, a process discovered 21 years before. The chemical method using potassium yielded only small grains of beryllium from which no ingot of metal could be cast or hammered. The direct electrolysis of a molten mixture of beryllium fluoride and sodium fluoride by Paul Lebeau in 1898 resulted in the first pure (99.5 to 99.8%) samples of beryllium. However, industrial production started only after the First World War. The original industrial involvement included subsidiaries and scientists related to the Union Carbide and Carbon Corporation in Cleveland, Ohio, and Siemens & Halske AG in Berlin. In the US, the process was ruled by Hugh S. Cooper, director of The Kemet Laboratories Company. In Germany, the first commercially successful process for producing beryllium was developed in 1921 by Alfred Stock and Hans Goldschmidt. A sample of beryllium was bombarded with alpha rays from the decay of radium in a 1932 experiment by James Chadwick that uncovered the existence of the neutron. This same method is used in one class of radioisotope-based laboratory neutron sources that produce 30 neutrons for every million α particles. Beryllium production saw a rapid increase during World War II, due to the rising demand for hard beryllium-copper alloys and phosphors for fluorescent lights. Most early fluorescent lamps used zinc orthosilicate with varying content of beryllium to emit greenish light. Small additions of magnesium tungstate improved the blue part of the spectrum to yield an acceptable white light. Halophosphate-based phosphors replaced beryllium-based phosphors after beryllium was found to be toxic. Electrolysis of a mixture of beryllium fluoride and sodium fluoride was used to isolate beryllium during the 19th century. The metal's high melting point makes this process more energy-consuming than corresponding processes used for the alkali metals. Early in the 20th century, the production of beryllium by the thermal decomposition of beryllium iodide was investigated following the success of a similar process for the production of zirconium, but this process proved to be uneconomical for volume production. Pure beryllium metal did not become readily available until 1957, even though it had been used as an alloying metal to harden and toughen copper much earlier. Beryllium could be produced by reducing beryllium compounds such as beryllium chloride with metallic potassium or sodium. Currently, most beryllium is produced by reducing beryllium fluoride with magnesium. The price on the American market for vacuum-cast beryllium ingots was about $338 per pound ($745 per kilogram) in 2001. Between 1998 and 2008, the world's production of beryllium had decreased from 343 to about 200 tonnes. It then increased to 230 tonnes by 2018, of which 170 tonnes came from the United States. Etymology Named after beryl, a semiprecious mineral, from which it was first isolated. Applications Radiation windows Because of its low atomic number and very low absorption for X-rays, the oldest and still one of the most important applications of beryllium is in radiation windows for X-ray tubes. Extreme demands are placed on purity and cleanliness of beryllium to avoid artifacts in the X-ray images. Thin beryllium foils are used as radiation windows for X-ray detectors, and the extremely low absorption minimizes the heating effects caused by high intensity, low energy X-rays typical of synchrotron radiation. Vacuum-tight windows and beam-tubes for radiation experiments on synchrotrons are manufactured exclusively from beryllium. In scientific setups for various X-ray emission studies (e.g., energy-dispersive X-ray spectroscopy) the sample holder is usually made of beryllium because its emitted X-rays have much lower energies (≈100 eV) than X-rays from most studied materials. Low atomic number also makes beryllium relatively transparent to energetic particles. Therefore, it is used to build the beam pipe around the collision region in particle physics setups, such as all four main detector experiments at the Large Hadron Collider (ALICE, ATLAS, CMS, LHCb), the Tevatron and at SLAC. The low density of beryllium allows collision products to reach the surrounding detectors without significant interaction, its stiffness allows a powerful vacuum to be produced within the pipe to minimize interaction with gases, its thermal stability allows it to function correctly at temperatures of only a few degrees above absolute zero, and its diamagnetic nature keeps it from interfering with the complex multipole magnet systems used to steer and focus the particle beams. Mechanical applications Because of its stiffness, light weight and dimensional stability over a wide temperature range, beryllium metal is used for lightweight structural components in the defense and aerospace industries in high-speed aircraft, guided missiles, spacecraft, and satellites, including the James Webb Space Telescope. Several liquid-fuel rockets have used rocket nozzles made of pure beryllium. Beryllium powder was itself studied as a rocket fuel, but this use has never materialized. A small number of extreme high-end bicycle frames have been built with beryllium. From 1998 to 2000, the McLaren Formula One team used Mercedes-Benz engines with beryllium-aluminium-alloy pistons. The use of beryllium engine components was banned following a protest by Scuderia Ferrari. Mixing about 2.0% beryllium into copper forms an alloy called beryllium copper that is six times stronger than copper alone. Beryllium alloys are used in many applications because of their combination of elasticity, high electrical conductivity and thermal conductivity, high strength and hardness, nonmagnetic properties, as well as good corrosion and fatigue resistance. These applications include non-sparking tools that are used near flammable gases (beryllium nickel), in springs and membranes (beryllium nickel and beryllium iron) used in surgical instruments and high temperature devices. As little as 50 parts per million of beryllium alloyed with liquid magnesium leads to a significant increase in oxidation resistance and decrease in flammability. The high elastic stiffness of beryllium has led to its extensive use in precision instrumentation, e.g. in inertial guidance systems and in the support mechanisms for optical systems. Beryllium-copper alloys were also applied as a hardening agent in "Jason pistols", which were used to strip the paint from the hulls of ships. Beryllium was also used for cantilevers in high performance phonograph cartridge styli, where its extreme stiffness and low density allowed for tracking weights to be reduced to 1 gram, yet still track high frequency passages with minimal distortion. An earlier major application of beryllium was in brakes for military airplanes because of its hardness, high melting point, and exceptional ability to dissipate heat. Environmental considerations have led to substitution by other materials. To reduce costs, beryllium can be alloyed with significant amounts of aluminium, resulting in the AlBeMet alloy (a trade name). This blend is cheaper than pure beryllium, while still retaining many desirable properties. Mirrors Beryllium mirrors are of particular interest. Large-area mirrors, frequently with a honeycomb support structure, are used, for example, in meteorological satellites where low weight and long-term dimensional stability are critical. Smaller beryllium mirrors are used in optical guidance systems and in fire-control systems, e.g. in the German-made Leopard 1 and Leopard 2 main battle tanks. In these systems, very rapid movement of the mirror is required which again dictates low mass and high rigidity. Usually the beryllium mirror is coated with hard electroless nickel plating which can be more easily polished to a finer optical finish than beryllium. In some applications, though, the beryllium blank is polished without any coating. This is particularly applicable to cryogenic operation where thermal expansion mismatch can cause the coating to buckle. The James Webb Space Telescope has 18 hexagonal beryllium sections for its mirrors, each plated with a thin layer of gold. Because JWST will face a temperature of 33 K, the mirror is made of gold-plated beryllium, capable of handling extreme cold better than glass. Beryllium contracts and deforms less than glass – and remains more uniform – in such temperatures. For the same reason, the optics of the Spitzer Space Telescope are entirely built of beryllium metal. Magnetic applications Beryllium is non-magnetic. Therefore, tools fabricated out of beryllium-based materials are used by naval or military explosive ordnance disposal teams for work on or near naval mines, since these mines commonly have magnetic fuzes. They are also found in maintenance and construction materials near magnetic resonance imaging (MRI) machines because of the high magnetic fields generated. In the fields of radio communications and powerful (usually military) radars, hand tools made of beryllium are used to tune the highly magnetic klystrons, magnetrons, traveling wave tubes, etc., that are used for generating high levels of microwave power in the transmitters. Nuclear applications Thin plates or foils of beryllium are sometimes used in nuclear weapon designs as the very outer layer of the plutonium pits in the primary stages of thermonuclear bombs, placed to surround the fissile material. These layers of beryllium are good "pushers" for the implosion of the plutonium-239, and they are good neutron reflectors, just as in beryllium-moderated nuclear reactors. Beryllium is also commonly used in some neutron sources in laboratory devices in which relatively few neutrons are needed (rather than having to use a nuclear reactor, or a particle accelerator-powered neutron generator). For this purpose, a target of beryllium-9 is bombarded with energetic alpha particles from a radioisotope such as polonium-210, radium-226, plutonium-238, or americium-241. In the nuclear reaction that occurs, a beryllium nucleus is transmuted into carbon-12, and one free neutron is emitted, traveling in about the same direction as the alpha particle was heading. Such alpha decay driven beryllium neutron sources, named "urchin" neutron initiators, were used in some early atomic bombs. Neutron sources in which beryllium is bombarded with gamma rays from a gamma decay radioisotope, are also used to produce laboratory neutrons. Beryllium is also used in fuel fabrication for CANDU reactors. The fuel elements have small appendages that are resistance brazed to the fuel cladding using an induction brazing process with Be as the braze filler material. Bearing pads are brazed in place to prevent contact between the fuel bundle and the pressure tube containing it, and inter-element spacer pads are brazed on to prevent element to element contact. Beryllium is also used at the Joint European Torus nuclear-fusion research laboratory, and it will be used in the more advanced ITER to condition the components which face the plasma. Beryllium has also been proposed as a cladding material for nuclear fuel rods, because of its good combination of mechanical, chemical, and nuclear properties. Beryllium fluoride is one of the constituent salts of the eutectic salt mixture FLiBe, which is used as a solvent, moderator and coolant in many hypothetical molten salt reactor designs, including the liquid fluoride thorium reactor (LFTR). Acoustics The low weight and high rigidity of beryllium make it useful as a material for high-frequency speaker drivers. Because beryllium is expensive (many times more than titanium), hard to shape due to its brittleness, and toxic if mishandled, beryllium tweeters are limited to high-end home, pro audio, and public address applications. Some high-fidelity products have been fraudulently claimed to be made of the material. Some high-end phonograph cartridges used beryllium cantilevers to improve tracking by reducing mass. Electronic Beryllium is a p-type dopant in III-V compound semiconductors. It is widely used in materials such as GaAs, AlGaAs, InGaAs and InAlAs grown by molecular beam epitaxy (MBE). Cross-rolled beryllium sheet is an excellent structural support for printed circuit boards in surface-mount technology. In critical electronic applications, beryllium is both a structural support and heat sink. The application also requires a coefficient of thermal expansion that is well matched to the alumina and polyimide-glass substrates. The beryllium-beryllium oxide composite "E-Materials" have been specially designed for these electronic applications and have the additional advantage that the thermal expansion coefficient can be tailored to match diverse substrate materials. Beryllium oxide is useful for many applications that require the combined properties of an electrical insulator and an excellent heat conductor, with high strength and hardness, and a very high melting point. Beryllium oxide is frequently used as an insulator base plate in high-power transistors in radio frequency transmitters for telecommunications. Beryllium oxide is also being studied for use in increasing the thermal conductivity of uranium dioxide nuclear fuel pellets. Beryllium compounds were used in fluorescent lighting tubes, but this use was discontinued because of the disease berylliosis which developed in the workers who were making the tubes. Healthcare Beryllium is a component of several dental alloys. Toxicity and safety Biological effects Approximately 35 micrograms of beryllium is found in the average human body, an amount not considered harmful. Beryllium is chemically similar to magnesium and therefore can displace it from enzymes, which causes them to malfunction. Because Be2+ is a highly charged and small ion, it can easily get into many tissues and cells, where it specifically targets cell nuclei, inhibiting many enzymes, including those used for synthesizing DNA. Its toxicity is exacerbated by the fact that the body has no means to control beryllium levels, and once inside the body, beryllium cannot be removed. Inhalation Chronic beryllium disease (CBD), or berylliosis, is a pulmonary and systemic granulomatous disease caused by inhalation of dust or fumes contaminated with beryllium; either large amounts over a short time or small amounts over a long time can lead to this ailment. Symptoms of the disease can take up to five years to develop; about a third of patients with it die and the survivors are left disabled. The International Agency for Research on Cancer (IARC) lists beryllium and beryllium compounds as Category 1 carcinogens. Occupational exposure In the US, the Occupational Safety and Health Administration (OSHA) has designated a permissible exposure limit (PEL) for beryllium and beryllium compounds of 0.2 µg/m3 as an 8-hour time-weighted average (TWA) and 2.0 µg/m3 as a short-term exposure limit over a sampling period of 15 minutes. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) upper-bound threshold of 0.5 µg/m3. The IDLH (immediately dangerous to life and health) value is 4 mg/m3. The toxicity of beryllium is on par with other toxic metalloids/metals, such as arsenic and mercury. Exposure to beryllium in the workplace can lead to a sensitization immune response and can over time develop chronic beryllium disease. The National Institute for Occupational Safety and Health (NIOSH) in the United States researches these effects in collaboration with a major manufacturer of beryllium products. NIOSH also conducts genetic research on sensitization and CBD, independently of this collaboration. Acute beryllium disease in the form of chemical pneumonitis was first reported in Europe in 1933 and in the United States in 1943. A survey found that about 5% of workers in plants manufacturing fluorescent lamps in 1949 in the United States had beryllium-related lung diseases. Chronic berylliosis resembles sarcoidosis in many respects, and the differential diagnosis is often difficult. It killed some early workers in nuclear weapons design, such as Herbert L. Anderson. Beryllium may be found in coal slag. When the slag is formulated into an abrasive agent for blasting paint and rust from hard surfaces, the beryllium can become airborne and become a source of exposure. Although the use of beryllium compounds in fluorescent lighting tubes was discontinued in 1949, potential for exposure to beryllium exists in the nuclear and aerospace industries and in the refining of beryllium metal and melting of beryllium-containing alloys, the manufacturing of electronic devices, and the handling of other beryllium-containing material. Detection Early researchers undertook the highly hazardous practice of identifying beryllium and its various compounds from its sweet taste. Identification is now performed using safe modern diagnostics techniques. A successful test for beryllium in air and on surfaces has been developed and published as an international voluntary consensus standard ASTM D7202. The procedure uses dilute ammonium bifluoride for dissolution and fluorescence detection with beryllium bound to sulfonated hydroxybenzoquinoline, allowing up to 100 times more sensitive detection than the recommended limit for beryllium concentration in the workplace. Fluorescence increases with increasing beryllium concentration. The new procedure has been successfully tested on a variety of surfaces and is effective for the dissolution and detection of refractory beryllium oxide and siliceous beryllium in minute concentrations (ASTM D7458). The NIOSH Manual of Analytical Methods contains methods for measuring occupational exposures to beryllium. References Cited sources Further reading Mroz MM, Balkissoon R, Newman LS. "Beryllium".

Britney Spears

Britney Jean Spears (born December 2, 1981) is an American singer. Often referred to as the "Princess of Pop", she is credited with influencing the revival of teen pop during the late 1990s and early 2000s. Spears has sold over 150 million records worldwide, including over 70 million in the United States, making her one of the world's best-selling music artists. She has earned numerous awards and accolades, including a Grammy Award, 15 Guinness world records, six MTV Video Music Awards, seven Billboard Music Awards (including the Millennium Award), the inaugural Radio Disney Icon Award, and a star on the Hollywood Walk of Fame. Her heavily choreographed videos earned her the Michael Jackson Video Vanguard Award. After appearing in stage productions and television series, Spears signed with Jive Records in 1997 at age fifteen. Her first two studio albums, ...Baby One More Time (1999) and Oops!... I Did It Again (2000), are among the best-selling albums of all time and made Spears the best-selling teenage artist of all time. With first-week sales of over 1.3 million copies, Oops!... I Did It Again held the record for the fastest-selling album by a female artist in the United States for fifteen years. Spears adopted a more mature and provocative style for her albums Britney (2001) and In the Zone (2003), and starred in the 2002 film Crossroads. She was executive producer of her fifth studio album, Blackout (2007), often referred to as her best work. Following a series of highly publicized personal problems, promotion for the album was limited, and Spears was involuntarily placed in a conservatorship. Subsequently, Spears released the chart-topping albums, Circus (2008) and Femme Fatale (2011), the latter of which became her most successful era of singles in the US charts. With "3" in 2009 and "Hold It Against Me" in 2011, Spears became the second artist after Mariah Carey in the Billboard Hot 100's history to debut at number one with two or more songs. She embarked on a four-year concert residency, Britney: Piece of Me, at Planet Hollywood Resort & Casino in Las Vegas to promote her next two albums Britney Jean (2013) and Glory (2016). In 2019, Spears's legal battle over her conservatorship became more publicized and led to the establishment of the #FreeBritney movement. In 2021, the conservatorship was terminated following her public testimony in which she accused her management team and family of abuse. In the United States, Spears is the fourth best-selling female album artist of the Nielsen SoundScan era, as well as the best-selling female album artist of the 2000s. She was ranked by Billboard as the eighth-biggest artist of the 2000s. The singer has amassed six number-one albums on the Billboard 200 and five number-one singles on the US Billboard Hot 100: "...Baby One More Time", "Womanizer", "3", "Hold It Against Me", and "S&M (Remix)". Other hit singles include "Oops!... I Did It Again", "I'm a Slave 4 U", and "Toxic". "...Baby One More Time" was named the greatest debut single of all time by Rolling Stone in 2020. In 2004, Spears launched a perfume brand with Elizabeth Arden, Inc.; sales exceeded $1.5 billion . Forbes has reported Spears as the highest-earning female musician of 2001 and 2012. By 2012, she had topped Yahoo!'s list of most searched celebrities seven times in twelve years. Time named Spears one of the 100 most influential people in the world in 2021, with Spears also placing first in the magazine's reader poll. Life and career 1981–1997: Early life, family, and career beginnings Britney Jean Spears was born on December 2, 1981, in McComb, Mississippi, the second child of James "Jamie" Parnell Spears and Lynne Irene Bridges. Her maternal grandmother, Lillian Portell, was English (born in London), and one of Spears's maternal grandfathers was Maltese. Her siblings are Bryan James Spears and Jamie Lynn Spears. In her memoir The Woman in Me, Spears wrote that her paternal grandmother, Jean, was sent to an asylum by Spears's paternal grandfather. Their three-day-old baby had died and Jean was overwhelmed by grief. While at the asylum, Jean was put on lithium; subsequently, she shot herself over the child's grave. Born in the Bible Belt, where socially conservative evangelical Protestantism is a particularly strong religious influence, she was baptized as a Southern Baptist and sang in a church choir as a child. As an adult, she has studied Kabbalist teachings. On August 5, 2021, Spears announced that she had converted to Catholicism. Her mother, sister, and nieces Maddie Aldridge and Ivey Joan Watson, are also Catholic. However, on September 5, 2022, after Spears's ex-husband, Kevin Federline, and youngest son did an interview defending her father's actions during her conservatorship, she stated: "I don't believe in God anymore because of the way my children and my family have treated me. There is nothing to believe in anymore. I'm an atheist y'all". At age three, Spears began attending dance lessons in her hometown of Kentwood, Louisiana, and was selected to perform as a solo artist at the annual recital. Aged five she made her local stage debut, singing "What Child Is This?" at her kindergarten graduation. During her childhood, she also had gymnastics and voice lessons, and won many state-level competitions and children's talent shows. In gymnastics, Spears attended Béla Károlyi's training camp. She said of her ambition as a child, "I was in my own world, ... I found out what I'm supposed to do at an early age". When Spears was eight, she and her mother Lynne traveled to Atlanta, Georgia, to audition for the 1990s revival of The Mickey Mouse Club. Casting director Matt Casella rejected her as too young, but introduced her to Nancy Carson, a New York City talent agent. Carson was impressed with Spears's singing and suggested enrolling her at the Professional Performing Arts School; shortly afterward, Lynne and her daughters moved to a sublet apartment in New York. Spears was hired for her first professional role as the understudy for the lead role of Tina Denmark in the off-Broadway musical Ruthless! She also appeared as a contestant on the popular television show Star Search and was cast in a number of commercials. In December 1992, she was cast in The Mickey Mouse Club alongside Christina Aguilera, Justin Timberlake, Ryan Gosling, and Keri Russell. After the show was canceled in 1994, she returned to Mississippi and enrolled at McComb's Parklane Academy. Although she made friends with most of her classmates, she compared the school to "the opening scene in Clueless with all the cliques. ... I was so bored. I was the point guard on the basketball team. I had my boyfriend, and I went to homecoming and Christmas formal. But I wanted more." In June 1997, Spears was in talks with manager Lou Pearlman to join the female pop group Innosense. Lynne asked family friend and entertainment lawyer Larry Rudolph for his opinion and submitted a tape of Spears singing over a Whitney Houston karaoke song along with some pictures. Rudolph decided that he wanted to pitch her to record labels, for which she needed a professional demo made. He sent Spears an unused song of Toni Braxton; she rehearsed for a week and recorded her vocals in a studio. Spears traveled to New York with the demo and met with executives from four labels, returning to Kentwood the same day. Three of the labels rejected her, saying that audiences wanted pop bands such as the Backstreet Boys and the Spice Girls, and "there wasn't going to be another Madonna, another Debbie Gibson, or another Tiffany." Two weeks later, executives from Jive Records returned calls to Rudolph. Senior vice president of A&R Jeff Fenster said about Spears's audition that "it's very rare to hear someone that age who can deliver emotional content and commercial appeal ... For any artist, the motivation—the 'eye of the tiger'—is extremely important. And Britney had that." Spears sang Houston's "I Have Nothing" (1992) for the executives, and was subsequently signed to the label. They assigned her to work with producer Eric Foster White for a month; he reportedly shaped her voice from "lower and less poppy" delivery to "distinctively, unmistakably Britney". After hearing the recorded material, president Clive Calder ordered a full album. Spears had originally envisioned "Sheryl Crow music, but younger; more adult contemporary". She felt secure with her label's appointment of producers, since "It made more sense to go pop, because I can dance to it—it's more me." She flew to Cheiron Studios in Stockholm, Sweden, where half of the album was recorded from March to April 1998, with producers Max Martin, Denniz Pop, and Rami Yacoub, among others. 1998–2000: ...Baby One More Time and Oops!... I Did It Again After Spears returned to the United States, she embarked on a shopping mall promotional tour, titled L'Oreal Hair Zone Mall Tour, to promote her upcoming debut album. Her show was a four-song set and she was accompanied by two back-up dancers. Her first concert tour followed, as an opening act for NSYNC. Her debut studio album, ...Baby One More Time, was released on January 12, 1999. It debuted at number one on the U.S. Billboard 200 and was certified two-times platinum by the Recording Industry Association of America after a month. Worldwide, the album topped the charts in fifteen countries and sold over 10 million copies in a year. It became the biggest-selling album ever by a teenage artist. "...Baby One More Time" was released as the lead single from the album. Originally, Jive Records wanted its music video to be animated; however, Spears rejected it, and suggested the final concept of a Catholic schoolgirl. The single sold 500,000 copies on its first day, and peaked at number one on the Billboard Hot 100, topping the chart for two consecutive weeks. It has sold more than 10 million copies, making it one of the best-selling singles of all time. "...Baby One More Time" later received a Grammy nomination for Best Female Pop Vocal Performance. The title track also topped the singles chart for two weeks in the United Kingdom, and became the fastest-selling single ever by a female artist, shipping over 460,000 copies. It would later become the 25th-most successful song of all time in British chart history. Spears is the youngest female artist to have a million seller in the UK. The album's third single "(You Drive Me) Crazy" became a top-ten hit worldwide and further propelled the success of the ...Baby One More Time album. The album has sold 25 million copies worldwide, making it one of the best-selling albums of all time. It is the best-selling debut album by any artist. On June 28, 1999, Spears began her first headlining ...Baby One More Time Tour in North America, which was positively received by critics. It also generated some controversy due to her racy outfits. An extension of the tour, titled (You Drive Me) Crazy Tour, followed in March 2000. Spears premiered songs from her upcoming second album during the show. Oops!... I Did It Again, Spears's second studio album, was released in May 2000. It debuted at number one in the US, selling 1.3 million copies, breaking the Nielsen SoundScan record for the highest debut sales by any solo artist. It has sold over 20 million copies worldwide to date, making it one of the best-selling albums of all time. Rob Sheffield of Rolling Stone said that "the great thing about Oops! – under the cheese surface, Britney's demand for satisfaction is complex, fierce and downright scary, making her a true child of rock & roll tradition." The album's lead single, "Oops!... I Did It Again", peaked at the top of the charts in Australia, New Zealand, the United Kingdom, and many other European nations, while the second single "Lucky", peaked at number one in Austria, Germany, Sweden, and Switzerland. The album as well as the title track received Grammy nominations for Best Pop Vocal Album and Best Female Pop Vocal Performance, respectively. The same year, Spears embarked on the Oops!... I Did It Again Tour, which grossed $40.5 million; she also released her first book, Britney Spears' Heart to Heart, co-written with her mother. On September 7, 2000, Spears performed at the 2000 MTV Video Music Awards. Halfway through the performance, she ripped off her black suit to reveal a sequined flesh-colored bodysuit, followed by heavy dance routine. It is noted by critics as the moment that Spears showed signs of becoming a more provocative performer. Amidst media speculation, Spears confirmed she was dating NSYNC member Justin Timberlake. Spears and Timberlake both graduated from high school via distance learning from the University of Nebraska High School. She also bought a home in Destin, Florida. In her 2023 memoir, Spears revealed that she had an abortion during late 2000 while dating Timberlake after he said they were not prepared for parenthood. Spears called the abortion "one of the most agonizing things I have ever experienced in my life." 2001–2002: Britney and Crossroads In January 2001, Spears hosted the 28th Annual American Music Awards, starred at Rock in Rio alongside NSYNC, and performed as a special guest in the Super Bowl XXXV halftime show headlined by Aerosmith and NSYNC. In February 2001, she signed a $7–8 million promotional deal with Pepsi, and released another book co-written with her mother, titled A Mother's Gift. Her self-titled third studio album, Britney, was released in November 2001. While on tour, she felt inspired by hip hop artists such as Jay-Z and The Neptunes and wanted to create a record with a funkier sound. The album debuted at number one in the Billboard 200 and reached top five positions in Australia, the United Kingdom, and mainland Europe, and has sold 10 million copies worldwide. Stephen Thomas Erlewine of AllMusic called Britney "the record where she strives to deepen her persona, making it more adult while still recognizably Britney. ... It does sound like the work of a star who has now found and refined her voice, resulting in her best record yet." The album was honored with two Grammy nominations—Best Pop Vocal Album and Best Female Pop Vocal Performance for "Overprotected"—and was listed in 2007 as one of Entertainment Weeklys "100 Best Albums from the Past 25 Years". The album's lead single, "I'm a Slave 4 U", became a top ten hit worldwide. Spears's performance of the single at the 2001 MTV Video Music Awards featured a caged tiger (wrangled by Bhagavan Antle) and a large albino python draped over her shoulders. It was harshly received by animal rights organization PETA, who claimed the animals were mistreated and scrapped plans for an anti-fur billboard that was to feature Spears. Jocelyn Vena of MTV summarized Spears's performance at the ceremony, saying, "draping herself in a white python and slithering around a steamy garden setting – surrounded by dancers in zebra and tiger outfits – Spears created one of the most striking visuals in the 27-year history of the show." To support the album, Spears embarked on the Dream Within a Dream Tour. The show was critically praised for its technical innovations, the pièce de résistance being a water screen that pumped two tons of water into the stage. The tour grossed $43.7 million, becoming the second highest-grossing tour of 2002 by a female artist, behind Cher's Farewell Tour. Her career success was highlighted by Forbes in 2002, as Spears was ranked the world's most powerful celebrity. Spears also landed her first starring role in Crossroads, released in February 2002. Although the film was largely panned, critics praised Spears's acting and the film was a box office success. Crossroads, which had a $12 million budget, went on to gross over $61.1 million worldwide. In June 2002, Spears opened her first restaurant, Nyla, in New York City, but terminated her relationship in November, citing mismanagement and "management's failure to keep her fully apprised". In July 2002, Spears announced she would take a six-month break from her career; however, she went back into the studio in November to record her new album. Spears's relationship with Justin Timberlake ended after three years. In November 2002, Timberlake released the song "Cry Me a River" as the second single from his solo debut album. The music video featured a Spears look-alike and fueled the rumors that she had been unfaithful to him, fueled by further rumors of a reported relationship with Limp Bizkit frontman Fred Durst, though Spears initially denied the allegations despite the two being spotted together on multiple occasions, even claiming the two had a friendly connection. As a response, Spears wrote the ballad "Everytime" with her backing vocalist and friend Annet Artani. 2003–2005: In the Zone and first two marriages In 2003, Spears worked with the electronic musician James Murphy of LCD Soundsystem, but the collaboration was unsuccessful. A track from their collaboration was leaked online in 2006. In August, Spears opened the MTV Video Music Awards with Christina Aguilera, performing "Like a Virgin". Halfway through they were joined by Madonna, whom they both kissed. The incident was highly publicized. In 2008, MTV listed the performance as the number-one opening moment in the history of MTV Video Music Awards, while Blender cited it as one of the 25 sexiest music moments on television history. Spears released her fourth studio album, In the Zone, in November 2003. She assumed more creative control by writing and co-producing most of the material. Vibe called it "A supremely confident dance record that also illustrates Spears's development as a songwriter." NPR listed the album as one of "The 50 Most Important Recording of the Decade", adding that "the decade's history of impeccably crafted pop is written on her body of work." In the Zone sold over 609,000 copies in the United States during its first week of availability in the United States, debuting at the top of the charts, making Spears the first female artist in the SoundScan era to have her first four studio albums to debut at number one. It also debuted at the top of the charts in France and the top ten in Belgium, Denmark, Sweden, and the Netherlands. The album produced four singles: "Me Against the Music", a collaboration with Madonna; "Toxic"—which won Spears her first Grammy for Best Dance Recording; "Everytime", and "Outrageous". In January 2004, Spears married her childhood friend at A Little White Wedding Chapel in Las Vegas, Nevada. The marriage was annulled 55 hours later, following a petition to the court that stated that Spears "lacked understanding of her actions". In March 2004, Spears embarked on The Onyx Hotel Tour in support of In the Zone. In June 2004, Spears fell and injured her left knee during the music video shoot for "Outrageous". Spears underwent arthroscopic surgery. She was forced to remain six weeks with a thigh brace, followed by eight to twelve weeks of rehabilitation, which caused The Onyx Hotel Tour to be canceled. During 2004, Spears became involved in the Kabbalah Centre through her friendship with Madonna. In July 2004, Spears became engaged to dancer Kevin Federline, whom she had met three months earlier. The romance was the subject of intense media attention, since Federline had recently broken up with actress Shar Jackson, who was still pregnant with their second child at the time. The stages of their relationship were chronicled in Spears's first reality show Britney and Kevin: Chaotic, which premiered on May 17, 2005, on UPN. Spears later referred to the show in a 2013 interview as "probably the worst thing I've done in my career". They held a wedding ceremony on September 18, 2004, but were not legally married until three weeks later on October 6 due to a delay finalizing the couple's prenuptial agreement. Shortly after, she released her first perfume, Curious, with Elizabeth Arden, which broke the company's first-week gross for a perfume. In October 2004, Spears took a career break to start a family. Greatest Hits: My Prerogative, her first greatest hits compilation album, was released in November 2004. Spears's cover version of Bobby Brown's "My Prerogative" was released as the lead single from the album, reaching the top of the charts in Finland, Ireland, Italy, and Norway. The second single, "Do Somethin'", was a top ten hit in Australia, the United Kingdom, and other countries of mainland Europe. In August 2005, Spears released "Someday (I Will Understand)", which was dedicated to her first child, a son named Sean Preston, who was born the following month. In November 2005, she released her first remix compilation, B in the Mix: The Remixes, which consists of 11 remixes. 2006–2007: Personal struggles and Blackout In February 2006, pictures surfaced of Spears driving with her son, Sean, on her lap instead of in a car seat. Child advocates were horrified by the photos of her holding the wheel with one hand and Sean with the other. Spears claimed that the situation happened because of a frightening encounter with paparazzi, and that it was a mistake on her part. The following month, she guest-starred on the Will & Grace episode "Buy, Buy Baby" as closeted lesbian Amber-Louise. She announced she no longer studied Kabbalah in May 2006, explaining, "my baby is my religion". Spears posed nude for the August 2006 cover of Harper's Bazaar; the photograph was compared to Demi Moore's August 1991 Vanity Fair cover. In September 2006, she gave birth to her second son, Jayden James. In November 2006, Spears filed for divorce from Federline, citing irreconcilable differences. Their divorce was finalized in July 2007, when the two reached a global settlement and agreed to share joint custody of their sons. Spears's maternal aunt Sandra Bridges Covington, with whom she had been very close, died of ovarian cancer in January 2007. In February, Spears stayed in a drug rehabilitation facility in Antigua for less than a day. The following night, she shaved her head with electric clippers at a hair salon in Tarzana, Los Angeles. She admitted herself to other treatment facilities during the following weeks. In May 2007, she produced a series of promotional concerts at House of Blues venues, titled The M+M's Tour. In October 2007, Spears lost physical custody of her sons to Federline. The reasons of the court ruling were not revealed to the public. Spears was also sued by Louis Vuitton over her 2005 music video "Do Somethin'" for upholstering her Hummer interior in counterfeit Louis Vuitton cherry blossom fabric, which resulted in the video being banned on European TV stations. In October 2007, Spears released her fifth studio album, Blackout. The album debuted atop the charts in Canada and Ireland, at number two in the U.S. Billboard 200, France, Japan, Mexico, and the United Kingdom, and the top ten in Australia, South Korea, New Zealand, and many European nations. In the United States, it was Spears's first album not to debut at number one, although, she did become the only female artist to have her first five studio albums debut at the two top slots of the chart. The album received positive reviews from critics and had sold 3.1 million copies worldwide by the end of 2008. Blackout won Album of the Year at the 2008 MTV Europe Music Awards and was listed as the fifth Best Pop Album of the Decade by The Times. Spears performed the lead single "Gimme More" at the 2007 MTV Video Music Awards. The performance was widely panned by critics. Despite the criticism, the single enjoyed worldwide success, peaking at number one in Canada and within the top ten in almost every country it charted. The second single "Piece of Me" reached the top of the charts in Ireland and reached the top five in Australia, Canada, Denmark, New Zealand, and the United Kingdom. The third single "Break the Ice" was released the following year, and respectively reached numbers seven and nine in Ireland and Canada. In December 2007, Spears began a relationship with paparazzo Adnan Ghalib. 2008–2010: Conservatorship and Circus In January 2008, Spears refused to relinquish custody of her sons to Federline's representatives. She was hospitalized at Cedars-Sinai Medical Center after police that had arrived at her house noted she appeared to be under the influence of an unidentified substance. The following day, Spears's visitation rights were suspended at an emergency court hearing, and Federline was given sole physical and legal custody of their sons. She was committed to the psychiatric ward of Ronald Reagan UCLA Medical Center and put on 5150 involuntary psychiatric hold under California state law. The court placed her under a conservatorship led by her father, Jamie Spears, and attorney Andrew Wallet, giving them complete control of her assets. She was released five days later. The following month, Spears guest-starred on the How I Met Your Mother episode "Ten Sessions" as receptionist Abby. She received positive reviews for her performance, as well as bringing the series its highest ratings ever. In July 2008, Spears regained some visitation rights after coming to an agreement with Federline and his counsel. In September 2008, Spears opened the MTV Video Music Awards with a pre-taped comedy sketch with Jonah Hill and an introduction speech. She won Best Female Video, Best Pop Video, and Video of the Year for "Piece of Me". A 60-minute introspective documentary, Britney: For the Record, was produced to chronicle Spears's return to the recording industry. Directed by Phil Griffin, For the Record was shot in Beverly Hills, Hollywood, and New York City during the third quarter of 2008. The documentary was broadcast on MTV to 5.6 million viewers for the two airings on the premiere night. It was the highest rating in its Sunday night timeslot and in the network's history. In December 2008, Spears's sixth studio album Circus was released. It received positive reviews from critics and debuted at number one in Canada, Czech Republic, and the United States, and within the top ten in many European nations. In the United States, Spears became the youngest female artist to have five albums debut at number one, earning a place in Guinness World Records. She also became the only act in the SoundScan era to have four albums debut with 500,000 or more copies sold. The album was one of the fastest-selling albums of the year, and has sold 4 million copies worldwide. Its lead single, "Womanizer", became Spears's first chart-topper on the Billboard Hot 100 since "...Baby One More Time". The single also topped the charts in Belgium, Canada, Denmark, Finland, France, Norway, and Sweden. It was also nominated for the Grammy Award for Best Dance Recording. In January 2009, Spears and her father obtained a restraining order against her former manager Sam Lutfi, ex-boyfriend Adnan Ghalib, and attorney Jon Eardley, all of whom had been accused of conspiring to gain control of Spears's affairs. Spears embarked on The Circus Starring Britney Spears tour in March 2009. With a gross of U.S. $131.8 million, it became the fifth highest-grossing tour of the year. In November 2009, Spears released her second greatest hits album, The Singles Collection. The album's lead and only single, "3", became her third number-one single in the U.S. In May 2010, Spears's representatives confirmed she was dating her agent, Jason Trawick, and that they had decided to end their professional relationship to focus on their personal relationship. Spears designed a limited edition clothing line for Candie's, which was released in stores in July 2010. In September 2010, she made a cameo appearance on a Spears-themed tribute episode of the television series Glee, titled "Britney/Brittany"; the episode drew the highest Nielsen ratingup to that point in the series's runin the 18–49 demographic. 2011–2012: Femme Fatale and The X Factor In March 2011, Spears released her seventh studio album, Femme Fatale. The album peaked at number one in the United States, Canada, and Australia, and within the top ten on nearly every other chart. Its peak in the United States tied Spears with Mariah Carey and Janet Jackson for the third-most number ones among women. Femme Fatale has been certified platinum by the RIAA and as of February 2014, it had sold 2.4 million copies worldwide. The album's lead single, "Hold It Against Me" debuted atop the Billboard Hot 100, becoming Spears's fourth number-one single on the chart and making her the second artist in history to have two consecutive singles debut at number one, after Mariah Carey. The second single "Till the World Ends" peaked at number three on the Billboard Hot 100 in May, while the third single "I Wanna Go" reached number seven in August. Femme Fatale became Spears's first album in which three of its songs reached the top ten of the chart. The fourth and final single "Criminal" was released in September 2011. The music video sparked controversy when British politicians criticized Spears for using replica guns while filming the video in a London area that had been badly affected by the 2011 England riots. Spears's management briefly responded, stating, "The video is a fantasy story featuring Britney's boyfriend, Jason Trawick, which literally plays out the lyrics of a song written three years before the riots ever happened." In April 2011, Spears appeared in a remix of Rihanna's song "S&M". It reached number one in the US later that month, giving Spears her fifth number one on the chart. On Billboards 2011 Year-End list, Spears was ranked number fourteen on the Artists of the Year, thirty-two on Billboard 200 artists, and ten on Billboard Hot 100 artists. Spears co-wrote "Whiplash", a song from the album When the Sun Goes Down (2011) by Selena Gomez & the Scene. In June 2011, Spears embarked on her Femme Fatale Tour. The first ten dates of the tour grossed $6.2 million, landing the fifty-fifth spot on Pollstar's Top 100 North American Tours list for the half-way point of the year. The tour ended on December 10, 2011, in Puerto Rico after 79 performances. A DVD of the tour was released in November 2011. In August 2011, Spears received the Michael Jackson Video Vanguard Award at the 2011 MTV Video Music Awards. The next month, she released her second remix album, B in the Mix: The Remixes Vol. 2. In December 2011, Spears became engaged to her long-time boyfriend Jason Trawick, who had formerly been her agent. Trawick was legally granted a role as co-conservator, alongside her father, in April 2012. In May 2012, Spears was hired to replace Paula Abdul as a judge for the second season of the USA show of The X Factor, joining Simon Cowell, L.A. Reid, and fellow new judge Demi Lovato, who replaced Nicole Scherzinger. With a reported salary of $15 million, she became the highest-paid judge on a singing competition series in television history. However, Katy Perry broke her record in 2018 after Perry was signed for a $25-million salary to serve as a judge on ABC's revival of American Idol. Spears mentored the Teens category; her final act, Carly Rose Sonenclar, was named the runner-up of the season. Spears did not return for the show's third season and was replaced by Paulina Rubio. Spears appeared on the song "Scream & Shout" with will.i.am, which was released as the third single from his fourth studio album, #willpower (2013). The song later became Spears's sixth number-one single on the UK Singles Chart and peaked at number three on the Billboard Hot 100. "Scream & Shout" was among the best-selling songs of 2012 and 2013 with denoting sales of over 8.1 million worldwide, the accompanying music video was the third most-viewed video in 2013 on Vevo despite the video being released in 2012. In December 2012, Forbes named her music's top-earning woman of 2012, with estimated earnings of $58 million. 2013–2015: Britney Jean and Britney: Piece of Me Spears began work on her eighth studio album, Britney Jean, in December 2012, and enlisted will.i.am as its executive producer in May 2013. In January 2013, Spears and Jason Trawick ended their engagement. Trawick was also removed as Spears's co-conservator, restoring her father as the sole conservator. Following the breakup, she began dating David Lucado in March; the couple split in August 2014. During the production of Britney Jean, Spears recorded the song "Ooh La La" for the soundtrack of The Smurfs 2, which was released in June 2013. On September 17, 2013, she appeared on Good Morning America to announce her two-year concert residency at Planet Hollywood Resort & Casino in Las Vegas, titled Britney: Piece of Me. It began on December 27, 2013, and included a total of 100 shows throughout 2014 and 2015. During the same appearance, Spears announced that Britney Jean would be released on December 3, 2013, in the United States. It was released through RCA Records due to the disbandment of Jive Records in 2011, which had formed the joint RCA/Jive Label Group (initially known as BMG Label Group) between 2007 and 2011. Britney Jean became Spears's final project under her original recording contract with Jive, which had guaranteed the release of eight studio albums. The record received a low amount of promotion and had little commercial impact, reportedly due to time conflicts involving preparations for Britney: Piece of Me. Upon its release, the record debuted at number four on the U.S. Billboard 200 with first-week sales of 107,000 copies, becoming her lowest-peaking and lowest-selling album in the United States. Britney Jean debuted at number 34 on the UK Albums Chart, selling 12,959 copies in its first week. In doing so, it became Spears's lowest-charting and lowest-selling album in the country. "Work Bitch" was released as the lead single from Britney Jean in September 2013. It debuted and peaked at number 12 on the U.S. Billboard Hot 100 marking Spears's 31st entry on the chart and the fifth highest debut of her career on the chart, and her seventh in the top 20. It also marked Spears's 19th top 20 entry and overall her 23rd top 40 single. The song marked Spears's highest sales debut since her 2011 number-one single "Hold It Against Me". "Work Bitch" debuted and peaked at number seven on the UK Singles Chart. The song also peaked within the top ten of the charts in Brazil, Canada, France, Italy, Mexico, and Spain. The second single "Perfume" premiered in November 2013. It debuted and peaked at number 76 on the U.S. Billboard Hot 100. In October 2013, she was featured as a guest vocalist on the song "SMS (Bangerz)" by Miley Cyrus, from the latter's fourth studio album Bangerz (2013).

In March 2015, it was confirmed by People magazine that Spears would release a new single, "Pretty Girls", with Iggy Azalea, on May 4, 2015. The song debuted and peaked at number 29 on the Billboard Hot 100 and charted moderately in international territories. Spears and Azalea performed the track live at the 2015 Billboard Music Awards from The AXIS, the home of Spears's residency, to positive critical response. Entertainment Weekly praised the performance, noting "Spears gave one of her most energetic televised performances in years." On June 16, 2015, Giorgio Moroder released his album, Déjà Vu, that featured Spears on "Tom's Diner". The song was released as the fourth single from the album on October 9, 2015. In an interview, Moroder praised Spears's vocals and said that she did a "good job" with the song and also stated that Spears "sounds so good that you would hardly recognize her." At the 2015 Teen Choice Awards, Spears received the Candie's Style Icon Award, her ninth Teen Choice Award. In November 2015, Spears guest-starred as a fictionalized version of herself on The CW series, Jane the Virgin.

Along with "Make Me", Spears and G-Eazy also performed the latter's hit song "Me, Myself & I". Spears appeared on the cover of Marie Claire UK for the October 2016 issue.

"My boys don't care if everything isn't perfect. They don't judge me", Spears said in the issue. In November 2016, during an interview with Las Vegas Blog, Spears confirmed she had already begun work on her next album, stating: "I'm not sure what I want the next album to sound like. ...

In January 2018, Spears released her 24th perfume with Elizabeth Arden, Sunset Fantasy, and announced the Piece of Me Tour which took place in July 2018 in North America and Europe. Tickets were sold out within minutes for major cities, and additional dates were added to meet the demand. Pitbull was the supporting act for the European leg.

On October 21, 2018, Spears performed at the Formula One Grand Prix in Austin, the final performance of her Piece of Me Tour. 2019–2021: Conservatorship dispute, #FreeBritney, and abuse allegations On January 4, 2019, Spears announced an indefinite hiatus and the cancellation of her Las Vegas residency after her father, Jamie, suffered a near-fatal colon rupture. In March 2019, Andrew Wallet resigned as co-conservator of her estate after 11 years. Spears entered a psychiatric facility amidst stress from her father's illness that same month. The following month, a fan podcast, Britney's Gram, released a voicemail message from a source who claimed to be a former member of Spears's legal team. They alleged that Jamie had canceled the residency due to Spears's refusal to take her medication, that he had been holding her in the facility against her will since January 2019 after she violated a no-driving rule, and that her conservatorship was supposed to have ended in 2009. The allegations gave rise to a movement to terminate the conservatorship, #FreeBritney, which received support from celebrities including singers Cher, Paris Hilton, and Miley Cyrus, and the nonprofit organization American Civil Liberties Union. On April 22, 2019, fans protested outside the West Hollywood City Hall and demanded Spears's release. Spears said "all [was] well" two days later and left the facility later that month. In a May 2019 hearing, Judge Brenda Penny ordered a professional evaluation of the conservatorship. In September, Spears's ex-husband Federline obtained a restraining order against Britney's father, Jamie, following an alleged physical altercation between Jamie and one of her sons. Spears's longtime care manager, Jodi Montgomery, temporarily replaced Jamie as her conservator that same month, which also saw a hearing where no decisions about the arrangement were reached. An interactive pop-up museum dedicated to Spears, dubbed "The Zone", opened in Los Angeles in February 2020, though it was later suspended in the wake of the COVID-19 pandemic. She released Glorys Japanese-exclusive bonus track, "Mood Ring" as a single, and debuted a new cover of the album to streaming and digital platforms worldwide in May 2020. In August, Jamie called the #FreeBritney movement "a joke" and its organizers "conspiracy theorists". On August 17, 2020, Spears's court-appointed lawyer, Samuel D. Ingham III, submitted a court filing that documented Spears's desire to have her conservatorship altered to reflect her wishes as well as lifestyle, to instate Montgomery as her permanent conservator, and to replace Jamie with a fiduciary as conservator of her estate. Four days later, Penny extended the established arrangement until February 2021. In November 2020, Penny approved Bessemer Trust as co-conservator of Spears's estate alongside Jamie. The following month, Spears released a new deluxe edition of Glory, which includes "Mood Ring" and new songs "Swimming in the Stars" and "Matches". A documentary about Spears's career and conservatorship, Framing Britney Spears, premiered on FX in February 2021. Spears later revealed that she had seen parts of the documentary, stating that she felt humiliated by the perception of her that was presented and that she "cried for two weeks" following the initial broadcast. The following month, Ingham filed a petition to permanently replace Jamie with Montgomery as the conservator of Spears's person, citing a 2014 order that determined that Spears did not have the capacity to consent to medical treatment of any form. On June 22, 2021, shortly before Spears was set to speak to the court, The New York Times obtained confidential court documents stating that Spears had pushed for years to end her conservatorship. Spears spoke to the court on June 23, calling the conservatorship "abusive". She said she had lied by "telling the whole world I'm OK and I'm happy", and that she was traumatized and angry. The court statement received widespread media coverage and generated over 1 million shares on Twitter, over 500,000 messages using the tag #FreeBritney, and more than 150,000 messages with a new hashtag referencing the court appearance, #BritneySpeaks. On July 1, Bessemer Trust asked the judge to allow them to withdraw from the conservatorship, saying that they had been misled and had entered into the arrangement on the understanding that the conservatorship was voluntary. The same day, senators Elizabeth Warren and Bob Casey Jr. called on federal agencies to increase oversight of the country's conservatorship systems. Spears's manager of 25 years, Larry Rudolph, resigned on July 6 due to her "intention to officially retire" and on that same day, it was reported that Ingham planned to file documents to the court asking to be dismissed. In a July 14 hearing, Judge Penny approved the resignations of Bessemer Trust and Ingham. The court also approved of Spears's request to hire attorney Mathew S. Rosengart to represent her. Rosengart informed the court that he would be working to terminate the conservatorship. Later that day, Spears publicly endorsed the #FreeBritney movement for the first time, using the hashtag in a caption on an Instagram post. She mentioned feeling "blessed" after earning "real representation", referring to Judge Penny's decision to allow her to choose her own counsel. On July 26, Rosengart filed a petition seeking to remove Jamie as conservator of Spears's estate and to replace him with Jason Rubin, a Certified Public Accountant (CPA) at Certified Strategies Inc. in Woodland Hills, California. On August 12, Jamie agreed to step down as conservator at some future date, with his lawyers stating that he wanted "an orderly transition to a new conservator". On September 7, Jamie filed a petition to end the conservatorship. Five days later, Spears announced her engagement to her longtime boyfriend, Sam Asghari, through an Instagram post. On September 29, Judge Penny suspended Jamie as conservator of Spears's estate, with accountant John Zabel replacing him on a temporary basis. On November 12, Judge Penny terminated the conservatorship. 2022–present: Third marriage, musical collaborations, and The Woman in Me In April 2022, she announced her pregnancy with Asghari's child, which ended in a miscarriage the following month. The couple married on June 9 at her home in Thousand Oaks, Los Angeles. None of Spears's immediate family (including her parents, sister, and brother) were invited; her two sons did not attend. Spears's first husband, Jason Alexander, attempted to crash the wedding by breaking into her home, armed with a knife, but was arrested. Spears had a three-year restraining order against him. On August 26, Spears and English musician Elton John released the duet "Hold Me Closer", a remake of John's 1972 single "Tiny Dancer". It was Spears's first musical release since the termination of her conservatorship. "Hold Me Closer" debuted at number six on the US Billboard Hot 100, becoming her 14th top-ten single and her highest-charting song in the chart since "Scream & Shout" (2012). It debuted at number three on the UK Singles Chart, earning Spears her 24th top-ten. Since the termination of her conservatorship, Spears's personal life, social media presence, and overall well-being have been subject to renewed media interest and fan speculation, giving rise to conspiracy theories. On January 24, 2023, deputies from the Ventura County Sheriff's Office performed a welfare check at Spears's residence after receiving several calls from fans who were concerned after she deleted her Instagram account. A spokesperson for the Sheriff's Department stated that Spears "was safe and in no danger." Spears addressed the incident on her Twitter account, asking fans to respect her privacy. Spears and the rapper will.i.am released their single, "Mind Your Business", on July 21, 2023. On August 16, it was announced Spears and Asghari separated after 14 months of marriage. In September 2023, an additional welfare check was initiated when Spears posted an Instagram video of herself dancing with knives. Her security team assured the attending officer that there was no immediate threat to her safety, and the officer departed. Spears also clarified that the knives were not real. In February 2022, Spears signed a $15 million book deal for a memoir in one of the biggest book deals of all time. The memoir, The Woman in Me, was released on October 24, 2023. It details her rise to fame, public media events, her conservatorship, and her newfound freedom. Artistry Influences Spears has cited Madonna, Janet Jackson, and Whitney Houston as major influences, her "three favorite artists" as a child, whom she would "sing along to ... day and night in [her] living room"; Houston's "I Have Nothing" was the song she auditioned to that landed her record deal with Jive Records. Spears also named Mariah Carey as "one of the main reasons I started singing". Throughout her career, Spears has drawn frequent comparisons to Madonna and Jackson in particular, in terms of vocals, choreography, and stage presence. According to Spears: "I know when I was younger, I looked up to people ... like, you know, Janet Jackson and Madonna. And they were major inspirations for me. But I also had my own identity and I knew who I was." In the 2002 book Madonnastyle by Carol Clerk, she is quoted saying: "I have been a huge fan of Madonna since I was a little girl. She's the person that I've really looked up to. I would really, really like to be a legend like Madonna." Spears cited "That's the Way Love Goes" as the inspiration for her song "Touch of My Hand" from her album In the Zone, saying "I like to compare it to 'That's the Way Love Goes,' kind of a Janet Jackson thing." She also said her song "Just Luv Me" from her Glory album also reminded her of "That's the Way Love Goes". After meeting Spears face to face, Janet Jackson stated: "she said to me, 'I'm such a big fan; I really admire you.' That's so flattering. Everyone gets inspiration from some place. And it's awesome to see someone else coming up who's dancing and singing, and seeing how all these kids relate to her. A lot of people put it down, but what she does is a positive thing." Madonna said of Spears in the documentary Britney: For the Record: "I admire her talent as an artist ... There are aspects about her that I recognize in myself when I first started out in my career". Spears has also named Michael Jackson, Mariah Carey, Sheryl Crow, Otis Redding, Shania Twain, Brandy, Beyoncé, Natalie Imbruglia, Cher, and Prince as inspirations, and younger artists such as Selena Gomez and Ariana Grande. Musical style Spears is described as a pop artist and generally explores the genre in the form of Following her debut, she was credited with influencing the revival of teen pop in the late 1990s. Rob Sheffield of Rolling Stone wrote: "Spears carries on the classic archetype of the rock & roll teen queen, the dungaree doll, the angel baby who just has to make a scene." In a review of ...Baby One More Time, Stephen Thomas Erlewine of AllMusic described her music as a "blend of infectious, rap-inflected dance-pop and smooth balladry." Oops!... I Did It Again saw Spears working with several R&B producers to create "a combination of bubblegum, urban soul, and raga". Her third studio album, Britney derived from the teen pop niche "[r]hythmically and melodically", but was described as "sharper, tougher than what came before", incorporating genres such as R&B, disco, and funk. Spears has explored and heavily incorporated the genres of electropop and dance music in her records, as well as influences of urban and hip hop, which are most present on In the Zone and Blackout. In the Zone also experiments with Euro trance, reggae, and Middle Eastern music. Femme Fatale and Britney Jean were also heavily influenced by electronic music genres. Spears's ninth studio album Glory is more eclectic and experimental than her previous released work. She commented that it "took a lot of time ... it's really different ... there are like two or three songs that go in the direction of more urban that I've wanted to do for a long time now, and I just haven't really done that." ...Baby One More Time and Oops!... I Did It Again address themes such as love and relationships from a teenager's point of view. Following the massive commercial success of her first two studio albums, Spears's team and producers wanted to maintain the formula that took her to the top of the charts. Spears, however, was no longer satisfied with the sound and themes covered on her records. She co-wrote five songs and choose each track's producer on her third studio album, Britney, which lyrics address the subjects of reaching adulthood, sexuality, and self-discovery. Sex, dancing, freedom, and love continued to be Spears's music main subjects on her subsequent albums. Her fifth studio effort, Blackout, also addresses issues such as fame and media scrutiny, including on the song "Piece of Me". Spears's music has also been noted for some catchphrases. The opening in her debut single "...Baby One More Time", "Oh, baby baby" is considered to be one of her signature lines and has been parodied in the media by various artists such as Nicole Scherzinger and Ariana Grande. It has been used in variating forms throughout her music, such as simply, "baby" and "oh baby", as well as the Blackout track, "Ooh Ooh Baby". On the initial development of "...Baby One More Time", Barry Weiss noted Spears's inception of the catchphrase from her strange ad-libbing during the recording of the song. He commented further, "We thought it was really weird at first. It was strange. It was not the way Max wrote it. But it worked! We thought it could be a really good opening salvo for her." The opening line in "Gimme More", "It's Britney, bitch" has become another signature phrase. An early review of Blackout suggested the phrase was "simply laughable". Amy Roberts of Bustle called it "an indelible cultural turning point, transforming a frenetic, floundering moment in the superstars career to one of strength and empowerment". Voice Spears is a soprano. Other sources state that she possesses a contralto vocal range. Prior to her breakthrough success, she is described as having sung "much deeper than her highly recognizable trademark voice of today", with Eric Foster White, who worked with Spears on her debut album ...Baby One More Time, being cited as "[shaping] her voice over the course of a month" upon being signed to Jive Records "to where it is today—distinctively, unmistakably Britney". Rami Yacoub, who co-produced Spears's debut album with lyricist Max Martin, commented, "I know from Denniz Pop and Max's previous productions, when we do songs, there's kind of a nasal thing. With N' Sync and the Backstreet Boys, we had to push for that mid-nasal voice. When Britney did that, she got this kind of raspy, sexy voice." Guy Blackman of The Age wrote that "[t]he thing about Spears, though, is that her biggest songs, no matter how committee-created or impossibly polished, have always been convincing because of her delivery, her commitment and her presence. ... Spears expresses perfectly the conflicting urges of adolescence, the tension between chastity and sexual experience, between hedonism and responsibility, between confidence and vulnerability." Producer William Orbit, who worked with Spears on her album Britney Jean, stated regarding her vocals: "[Britney] didn't get so big just because [she] put on great shows; [she] got to be that way because [her voice is] unique: you hear two words and you know who is singing". Spears has also been criticized for her reliance on Auto-Tune and her vocals being "over-processed" on records. Erlewine criticized Spears's singing abilities in a review of her Blackout album, stating: "Never the greatest vocalist, her thin squawk could be dismissed early in her career as an adolescent learning the ropes, but nearly a decade later her singing hasn't gotten any better, even if the studio tools to masquerade her weaknesses have." Joan Anderman of The Boston Globe remarked that "Spears sounds robotic, nearly inhuman, on her records, so processed is her voice by digital pitch-shifters and synthesizers." Kayla Upadhyaya of The Michigan Daily has provided a different point of view, stating: "Auto-tuned and over-processed vocals define [Spears]'s voice as an artist, and in her music, auto-tune isn't so much a gimmick as it is an instrument used to highlight, contort and make a statement." Adam Markovitz of Entertainment Weekly opines that "Spears is no technical singer, that's for sure. But backed by Martin and Dr. Luke's wall of pound, her vocals melt into a mix of babytalk coo and coital panting that is, in its own overprocessed way, just as iconic and propulsive as Michael Jackson's yips or Eminem's snarls." Stage performances and videos Spears is known for her stage performances, particularly the elaborate dance routines which incorporate "belly-dancing and tempered erotic moves" that are credited with influencing "dance-heavy acts" such as Danity Kane and the Pussycat Dolls. Rolling Stone readers voted Spears their second-favorite dancing musician. Spears is described as being much more shy than her stage persona suggests. She said that performing is "a boost to [her] confidence. It's like an alter-ego type thing. Something clicks and I go and turn into this different person. I think it's kind of a gift to be able to do that." Her 2000, 2001, and 2003 MTV Video Music Awards performances were lauded, while her 2007 presentation was widely panned by critics, as she "teetered through her dance steps and mouthed only occasional words". Billboard called her 2016 "comeback" performance at the show "an effective, but not entirely glorious, bid to regain pop superstardom". After her knee injuries and personal problems, Spears's "showmanship" and dance abilities came under criticism. Serge F. Kovaleski of The New York Times watched her Las Vegas concert residency in 2016 and stated: "Once a fluid, natural dancer, Ms. Spears can appear stiff, even robotic, today, relying on flailing arms and flashy sets." Las Vegas Suns Robin Leach seemed more impressed over Spears's efforts on the concert by saying that she delivered a "flawless performance" on the residency's opening night. It has been widely reported that Spears lip-syncs during live performances, which often prompts criticism from music critics and concert goers. Some, however, claimed that, although she "got plenty of digital support", she "doesn't merely lip-sync" during her live shows. In 2016, Sabrina Weiss of Refinery29 referred to her lip-syncing as a "well-known fact that's not even taboo anymore." Noting on the prevalence of lip-syncing, the Los Angeles Daily News opined: "In the context of a Britney Spears concert, does it really matter? ... you [just] go for the somewhat-ridiculous spectacle of it all". Spears herself has commented on the topic, arguing: "Because I'm dancing so much, I do have a little bit of playback, but there's a mixture of my voice and the playback. ... It really pisses me off because I'm busting my ass out there and singing at the same time and nobody ever gives me credit for it". In 2012, VH1 ranked Spears as the fourth Greatest Woman of the Video Era, while Billboard ranked her as the eight Greatest Music Video Artist of All Time in 2020, explaining: "The storylines, the dancing, the outfits. Right from the start, the pop princess established the lengths of her creativity with some of the most memorable videos of the last three decades." She has been retroactively noted as the pioneer for her early career videography. She conceptualized the "iconic Catholic schoolgirl and cheerleader motif" in the "...Baby One More Time" video, rejecting the animation video idea. She also made the "Oops!... I Did It Again" video "dance-centric rather than space-centric as her producers suggested". She also used her dancer's intuition to help select the beats for each track. Public image Upon launching her music career with ...Baby One More Time, Spears was labeled a teen idol, and Rolling Stone described her as "the latest model of a classic product: the unneurotic pop star who performs her duties with vaudevillian pluck and spokesmodel charm." The April 1999 cover of Rolling Stone featured Spears lying on her bed, wearing an open top revealing her bra, and shorts, while clutching a Teletubby. The American Family Association (AFA) referred to the shoot as "a disturbing mix of childhood innocence and adult sexuality" and called on "God-loving Americans to boycott stores selling Britney's albums." Spears addressed the outcry, commenting: "What's the big deal? I have strong morals. ... I'd do it again. I thought the pictures were fine. And I was tired of being compared to Debbie Gibson and all of this bubblegum pop all the time." Shortly prior, Spears had announced publicly she would remain abstinent until marriage. An early criticism of Spears dismissed her as a "manufactured pop star, the product of a Swedish songwriting factory that had no real hand in either her music or her persona", which Vox editor Constance Grady assesses as being perpetuated from the fact that Spears debuted in the late 1990s, when music was dominated by rockism, that prizes "so-called authenticity and grittiness of rock above all else". Spears's "slick, breezy pop was an affront to rockist sensibilities, and claiming that Spears was fake was an easy way to dismiss her." Ron Levy for Rolling Stone noted that "I have to tell you, if the record company could have created more than one Britney Spears, they would have done it, and they tried!" Billboard opined that, by the time Spears released her sophomore album Oops!... I Did It Again, "There was a shift occurring in both the music and her public image: She was sharper, sexier and singing about more grown-up fare, setting the stage for 2001's Britney, which shed her innocent skin and ushered her into adulthood." Britneys lead single "I'm a Slave 4 U" and its music video were also credited for distancing her from her previous "wholesome bubblegum star" image. Stephen Thomas Erlewine of AllMusic remarked, "If 2001's Britney was a transitional album, capturing Spears at the point when she wasn't a girl and not yet a woman, its 2003 follow-up, In the Zone, is where she has finally completed that journey and turned into Britney, the Adult Woman." Erlewine likened Spears to fellow singer Christina Aguilera, explaining that both equated "maturity with transparent sexuality and the pounding sounds of nightclubs". Brittany Spanos of LA Weekly stated that Spears "set the bar for the 'adulthood' transition teen pop stars often struggle with". Spears's erratic behavior and personal problems during 2006–2008 were highly publicized and affected both her career and public image. Erlewine reflected on this period of her life, stating that "each new disaster [was] stripping away any residual sexiness in her public image". In a 2008 article, Rolling Stones Vanessa Grigoriadis described her much-publicized personal issues as "the most public downfall of any star in history". Spears later received favorable media attention; Billboard opined that her appearance at the 2008 MTV Video Music Awards "was a picture of professionalism and poise" after her "disastrous" performance at the previous year's show, while Business Insider ran an article on how she had "lost control of her life ... and then made an incredible career comeback". Spears later reflected on this tumultuous period, saying: "I think I had to give myself more breaks through my career and take responsibility for my mental health. ... I wrote back then, that I was lost and didn't know what to do with myself. I was trying to please everyone around me because that's who I am deep inside. There are moments where I look back and think: 'What the hell was I thinking?'" In September 2002, Spears was placed at number eight on VH1's 100 Sexiest Artists list. She was placed at number one on FHMs 100 Sexiest Women in the World list in 2004, and, in December 2012, Complex ranked her 12th on its 100 Hottest Female Singers of All Time list. Remarking upon her perceived image as a sex symbol, Spears stated: "When I'm on stage, that's my time to do my thing and go there and be that and it's fun. It's exhilarating just to be something that you're not. And people tend to believe it." In 2003, People magazine cited her as one of the 50 Most Beautiful People. Spears is recognized as a gay icon and was honored with the 2018 GLAAD Vanguard Award at the GLAAD Media Awards for her role in "accelerating acceptance for the LGBTQ community". Spears addressed the "unwavering loyalty" and "lack of judgment" of her LGBTQ fans in Billboards Love Letters to the LGBTQ Community. She said: "Your stories are what inspire me, bring me joy, and make me and my sons strive to be better people." Manuel Betancourt of Vice magazine wrote about the "queer adoration", especially of gay men, on Spears, and said that "Where other gay icons exude self-possession, Spears' fragile resilience has made her an even more fascinating role model, closer to Judy Garland than to Lady Gaga ... she's a glittering mirror ball, a fractured reflection of those men on the dance floor back onto themselves." HuffPosts Ben Appel attributed Spears's status as a gay icon to "her oh-so-innocent/"not that innocent" Monroe-like sensuality, her sweet, almost saccharine nature, her beyond basic but addictive pop songs, her dance moves, her phoenix-out-of-the-fire comeback from a series of mental health crises, and her unmistakable tenderness. Britney is camp. She is a fashion plate. A doll. Britney is a drag queen." Since her early years in the public eye, Spears has been a tabloid fixture and a paparazzi target. Steve Huey of AllMusic remarked that "among female singers of [Spears's] era ... her celebrity star power was rivaled only by Jennifer Lopez." 'Britney Spears' was Yahoo!'s most popular search term between 2005 and 2008, and has been in a total of seven different years. Spears was named as Most Searched Person in the Guinness World Records book edition 2007 and 2009. She was later named as the most searched person of the decade 2000–2009. As a public figure, Spears "has never been known to her fans as a politically active, committed—or even aware—entertainer." In a 2003 interview with Tucker Carlson, she commented on President George W. Bush and the Iraq War, saying that "we should just trust our president in every decision that he makes ... and be faithful in what happens". Michael Moore included the footage of Spears's answer in his "anti-Bush" documentary Fahrenheit 9/11, which, according to The Washington Timess James Frazier, presented her "as an example of a naive American blindly trusting a dishonest commander in chief" and fueled the "urban legend" of a "conservative" Spears. Frazier also said that "the few positions she has taken can hardly be considered conservative", such as supporting same-sex marriage. In 2016, Spears posted pictures of a meeting with Hillary Clinton on social media. She described Clinton as "an inspiration and [a] beautiful voice for women around the world". In December 2017, Spears publicly showed support for the DREAM Act in the wake of the announcement that Donald Trump would end the DACA policy, which previously granted undocumented immigrants who came to the country as minors a renewable two-year period of deferred action from deportation. She posted a photo of herself on social media wearing a black T-shirt that reads "We Are All Dreamers" in white letters. The caption read, "Tell Congress to pass the #DreamAct". In 2020, amidst the COVID-19 pandemic, Spears posted an image on Instagram and wrote: "During this time of isolation ... We will feed each other, redistribute wealth, strike. We will understand our own importance from the places we must stay", along with three emoji roses, "a symbol commonly used by the Democratic Socialists of America". She later voiced support for the Black Lives Matter movement and George Floyd protests in the wake of his murder, saying: "My heart breaks for my friends in the black community ... and for everything going on in our country. Right now I think we should all do what we can to listen, learn, do better, and use our voices for good." On September 15, 2021, Spears was named one of the 100 most influential people of 2021 by Time. A few days before the editors's list was released, Spears was put at the top of the readers voting list of which personalities should be included on the annual Time 100 list. Deemed an icon of 2021, editors highlighted the impact of her fight against her conservatorship as well as of the #FreeBritney movement. In October 2021, Spears thanked her fans and the #FreeBritney movement for "freeing me from my conservatorship". Legacy Referred to as the "Princess of Pop", Spears was credited as one of the "driving force[s] behind the return of teen pop in the late 1990s". Rolling Stones Stacy Lambe explained that she "help[ed] to usher in a new era for the genre that had gone dormant in the decade that followed New Kids on the Block. ... Spears would lead an army of pop stars ... built on slick Max Martin productions, plenty of sexual innuendo and dance-heavy performances. [She became] one of the most successful artists of all time—and a cautionary tale for a generation, whether they paid attention or not." In a 2021 article for Time, Maura Johnston opined that "Spears' legacy as a pop artist is complex, made up of dazzling musical heights and music-business-borne lows". Johnston also commented: "While Spears' catalog is part of the canon that defines the first 20 years of this millennium, one hopes that her public struggles, and the strength she's shown while enduring them, will lead to her cementing her true legacy: Reshaping the machine that turns those songs into cultural touchstones." Glamour magazine contributor Christopher Rosa described her as "one of pop music's defining voices. ... When she emerged onto the scene in 1998 with ...Baby One More Time, the world hadn't seen a performer like her. Not since Madonna had a female artist affected the genre so profoundly." Billboards Robert Kelly observed that Spears's "sexy and coy" vocals on her debut single "...Baby One More Time" "kicked off a new era of pop vocal stylings that would influence countless artists to come." In 2020, Rolling Stone ranked the song at number one on a list of the 100 Greatest Debut Singles of All Time and Rob Sheffield described it as "One of those pop manifestos that announces a new sound, a new era, a new century. But most of all, a new star ... With "...Baby One More Time", [Spears] changed the sound of pop forever: It's Britney, bitch. Nothing was ever the same." Spears was at the forefront of the female teen pop explosion starting in 1999 and extending through the 2000s, leading the pack of Christina Aguilera, Jessica Simpson, and Mandy Moore. All of these performers had been developing material in 1998, but the market changed dramatically in December 1998 when Spears's single and video were charting highly. RCA Records quickly signed Aguilera and released her debut single to capitalize on Spears's success, producing her debut hit single "Genie in a Bottle". Simpson consciously modeled her persona as more mature than Spears; her "I Wanna Love You Forever" charted in September 1999, and her album Sweet Kisses followed shortly after. Moore's first single, "Candy", hit the airwaves a month before Simpson's single, but it did not perform as well on the charts; Moore was often seen as less accomplished than Spears and the others, coming in fourth of the "pop princesses". Fueling media stories about their competition for first place, Spears and Aguilera traded barbs but also compliments through the 2000s. Alim Kheraj of Dazed called Spears "one of pop's most important pioneers". After eighteen years as a performer, Billboard described her as having "earned her title as one of pop's reigning queens. Since her early days as a Mouseketeer, [Spears] has pushed the boundaries of 21st century sounds, paving the way for a generation of artists to shamelessly embrace glossy pop and redefine how one can accrue consistent success in the music industry." Entertainment Weeklys Adam Markovitz described Spears as "an American institution, as deeply sacred and messed up as pro wrestling or the filibuster." In 2012, she was ranked as the fourth VH1's 50 Greatest Women of the Video Era show list. VH1 also cited her among its choices on the 100 Greatest Women in Music in 2012 and the 200 Greatest Pop Culture Icons in 2003. In 2020, Billboard ranked her eight on its 100 Greatest Music Video Artists of all-time list. Spears and her work have influenced various artists including Katy Perry, Meghan Trainor, Demi Lovato, Kelly Key, Kristinia DeBarge, Little Boots, Charli XCX, Marina Diamandis, the Weeknd, Tegan and Sara, Pixie Lott, Grimes, Selena Gomez, Hailee Steinfeld, Pabllo Vittar, Tinashe, Victoria Justice, Cassie, Leah Wellbaum of Slothrust, the Saturdays, Normani, Miley Cyrus, Cheryl, Lana Del Rey, Ava Max, Billie Eilish, Sam Smith, and Rina Sawayama. During the 2011 MTV Video Music Awards, Lady Gaga said that Spears "taught us all how to be fearless, and the industry wouldn't be the same without her." Gaga has also cited Spears as an influence, calling her "the most provocative performer of my time." Before Spears joined The X Factor, Simon Cowell explained that he is "fascinated by [Britney]. The fact that she's one of the most talked about – not just pop stars – but people in the world today, means that you've got this star power. ... She's still hot, she's still having hit records and she's still controversial, there's a reason for that." Marina Diamandis named Spears as the main influence behind her album Electra Heart. Lana Del Rey has said that the music video for "Toxic" inspires her. Spears has had a direct influence on singer Porcelain Black's work after growing up around her music as a child. Black describes her music as a "love child between" Spears and Marilyn Manson. Rita Ora's 2019 music video for "Only Want You" was inspired by Spears's "Everytime" music video, and said in a stories from Instagram, "Hey @britneyspears this was for you because I love you so. Pay homage to the ones who inspire! #icon." Spears has been credited with redefining Las Vegas residencies as a retirement place for musicians. Her debut concert residency Britney: Piece of Me was described as "the natural evolution of Celine Dion's powerhourse Vegas residency, a still-charting star of another generation redefining the role of Strip headliner." Forbes named Spears the sixth-highest-earning female musician of 2015." She is credited with influencing and paving the way for other artists's residencies such as Jennifer Lopez's Jennifer Lopez: All I Have, Bruno Mars's Bruno Mars at Park MGM, and Backstreet Boys' Backstreet Boys: Larger Than Life. The arrival of Spears "saw the pop promoters finally tap into the younger crowd arriving in town for a good time." Spears's much-publicized personal problems and her subsequent career comeback have inspired some artists. Gwyneth Paltrow's character in the 2010 film Country Strong was inspired by Spears's treatment by the media. According to film director Shana Fest, "that's where this movie came from. I mean, I was seeing what was happening in the media to Britney Spears. I think it's tragic how we treat people who give us so much, and we love to see them knocked down to build them back up again, to knock them down again." Nicki Minaj has cited Spears's comeback after her much-publicized personal issues as an inspiration. Spears's hounding by paparazzi and personal problems also inspired Barry Manilow's album 15 Minutes. Manilow said: "She couldn't have a life without them pulling up next to her car and following her and driving her crazy to the point where, that was around the time she shaved off her hair. ... We all looked at it in horror ... So it seemed like a thing to be writing an album about." Bebo Norman wrote a song about Spears, called "Britney", which was inspired by "culture's make-or-break treatment of celebrities." Achievements Spears's awards and accolades include a Grammy Award; 15 Guinness world records; six MTV Video Music Awards, including the Michael Jackson Video Vanguard Award; seven Billboard Music Awards, including the Millennium Award; the inaugural Radio Disney Icon Award; the GLAAD Media Award's Vanguard Award; and a star on the Hollywood Walk of Fame. Spears is listed by the Guinness World Records as having the "Best-selling album by a teenage solo artist" for her debut studio album, ...Baby One More Time, which sold over 13 million copies in the United States. Melissa Ruggieri of the Richmond Times-Dispatch reported: "She's also marked for being the best-selling teenage artist. Before she turned 20 in 2001, Spears had sold over 37 million albums worldwide". , according to the Evening Standard, Spears has sold over 150 million records worldwide, making her one of the best-selling music artists of all time. She also sold more than 70 million records in United States, including 36.9 million digital singles and 33.6 million digital albums. Spears is further recognized as the best-selling female albums artist of the 2000s in the United States, as well as the fifth overall. In December 2009, Billboard ranked Spears the 8th Artist of the 2000s decade in the United States. She is one of the few artists in history to have had a number-one single and a number-one studio album in the US during each of the three decades of her career. With "3" in 2009 and "Hold It Against Me" in 2011, she became the second artist after Mariah Carey in the Hot 100's history to debut at number one with two or more songs. In 2016, Spears ranked at number twenty on Billboards Greatest Of All Time Top Dance Club Artists list. Other ventures Product and endorsements In 2000, Spears released a limited edition of sunglasses titled Shades of Britney. In 2001, she signed a deal with shoe company Skechers, and a $7–8 million promotional deal with Pepsi, their biggest entertainment deal at the time.

The philosophy behind the Foundation was that music and entertainment has a healing quality that can benefit children. The Foundation also supported the annual Britney Spears Camp for the Performing Arts, where campers had the opportunity to explore and develop their talents. In April 2002, through the efforts of Spears and The Britney Spears Foundation, a grant of $1 million was made to the Twin Towers Fund to support the children of uniformed service heroes affected by the terrorist attacks of September 11, 2001, including New York City Fire Department and its Emergency Medical Services Command, the New York City Police Department, the Port Authority of New York and New Jersey, the New York State Office of court Administration and other government offices. However, it was reported in 2008 that the Foundation had a deficit of $200,000. After Spears went through conservatorship, her father and lawyer Andrew Wallet zeroed out the effort, leading to its closure in 2011. On October 30, 2001, Spears, alongside Bono and other popular recording artists under the name "Artists Against AIDS Worldwide", released an album consisting of multiple versions of Marvin Gaye's "What's Going On", with the intention to benefit AIDS programs in Africa and other impoverished regions. In the wake of Hurricane Katrina in 2005, Spears donated $350,000 to Music Rising. Later in 2011, she raised $200,000 during An Evening of Southern Style at a private residence in Beverly Hills to benefit the St. Bernard Project, with the help of several celebrities, including Hilary Duff, Selena Gomez, Kelly Osbourne, Kellan Lutz, and Kim Kardashian. Spears has also helped several charities during her career, including Madonna's Kabbalah-based Spirituality for Kids, cancer charity Gilda's Club Worldwide, Promises Foundation, and United Way, with the latter two focused on giving families from various disadvantaged situations new hope and stable foundations for the future. On October 24, 2015, Spears donated $120,000 to the Nevada Childhood Cancer Foundation. In addition, $1 of each ticket sale for her Las Vegas residency, Britney: Piece of Me, was donated to the nonprofit organization. Spears also fundraised for the charity through social media, in addition to selling limited edition merchandise, with all proceeds going to the NCCF. On October 27, 2016, Spears partnered with Zappos and XCYCLE to host the Britney Spears Piece of Me Charity Ride in Boca Park, Las Vegas to raise additional money toward her goal of $1 million for the NCCF, with $450,000 having already been raised from Spears's ticket sales and merchandise. Participants were entered for a chance to win a spin class with Spears herself. The event ultimately went on to raise $553,130. The fundraising ultimately led to the development of the NCCF Britney Spears Campus in Las Vegas, which saw its grand opening on November 4, 2017. Spears also regularly participates in Spirit Day to combat bullying of LGBTQ youth and bullying. In March 2020, Spears was participating in the #DoYourPartChallenge, which entails helping people with anything they might need during the COVID-19 pandemic. She told fans to send her messages on Instagram if they need supportive words during the coronavirus pandemic, with Spears picking three fans. Discography ...Baby One More Time (1999) Oops!...

Brazil

Brazil (; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in South America and in Latin America. Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo. The federation is composed of the union of the 26 states and the Federal District. It is the only country in the Americas to have Portuguese as an official language. It is one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world, and the most populous Roman Catholic-majority country. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other countries and territories in South America except Ecuador and Chile and covers roughly half of the continent's land area. Its Amazon basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage positions Brazil at number one of 17 megadiverse countries, and is the subject of significant global interest, as environmental degradation through processes like deforestation has direct impacts on global issues like climate change and biodiversity loss. The territory which would become known as Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of explorer Pedro Álvares Cabral, who claimed the discovered land for the Portuguese Empire. Brazil remained a Portuguese colony until 1808 when the capital of the empire was transferred from Lisbon to Rio de Janeiro. In 1815, the colony was elevated to the rank of kingdom upon the formation of the United Kingdom of Portugal, Brazil and the Algarves. Independence was achieved in 1822 with the creation of the Empire of Brazil, a unitary state governed under a constitutional monarchy and a parliamentary system. The ratification of the first constitution in 1824 led to the formation of a bicameral legislature, now called the National Congress. Slavery was abolished in 1888. The country became a presidential republic in 1889 following a military coup d'état. An authoritarian military dictatorship emerged in 1964 and ruled until 1985, after which civilian governance resumed. Brazil's current constitution, formulated in 1988, defines it as a democratic federal republic. Due to its rich culture and history, the country ranks thirteenth in the world by number of UNESCO World Heritage Sites. Brazil is a regional and middle power and is also classified as an emerging power and a major non-NATO ally. Categorised as a developing country with a high Human Development Index, Brazil is considered an advanced emerging economy, having the ninth largest GDP in the world by nominal, and eighth by PPP measures, the largest in Latin America. As an upper-middle income economy by the World Bank and a newly industrialized country, Brazil has the largest share of global wealth in South America and it is one of the world's major breadbaskets, being the largest producer of coffee for the last 150 years. However, the country retains noticeable corruption, crime and social inequality. Brazil is a founding member of the United Nations, the G20, BRICS, G4, Mercosul, Organization of American States, Organization of Ibero-American States and the Community of Portuguese Language Countries. Brazil is also an Observer State of the Arab League. Etymology The word "Brazil" likely comes from the Portuguese word for brazilwood, a tree that once grew plentifully along the Brazilian coast. In Portuguese, brazilwood is called pau-brasil, with the word brasil commonly given the etymology "red like an ember", formed from brasa ("ember") and the suffix -il (from -iculum or -ilium). As brazilwood produces a deep red dye, it was highly valued by the European textile industry and was the earliest commercially exploited product from Brazil. Throughout the 16th century, massive amounts of brazilwood were harvested by indigenous peoples (mostly Tupi) along the Brazilian coast, who sold the timber to European traders (mostly Portuguese, but also French) in return for assorted European consumer goods. The official Portuguese name of the land, in original Portuguese records, was the "Land of the Holy Cross" (Terra da Santa Cruz), but European sailors and merchants commonly called it the "Land of Brazil" (Terra do Brasil) because of the brazilwood trade. The popular appellation eclipsed and eventually supplanted the official Portuguese name. Some early sailors called it the "Land of Parrots". In the Guaraní language, an official language of Paraguay, Brazil is called "Pindorama", meaning "land of the palm trees". History Pre-Cabraline era Some of the earliest human remains found in the Americas, Luzia Woman, were found in the area of Pedro Leopoldo, Minas Gerais and provide evidence of human habitation going back at least 11,000 years. The earliest pottery ever found in the Western Hemisphere was excavated in the Amazon basin of Brazil and radiocarbon dated to 8,000 years ago (6000 BC). The pottery was found near Santarém and provides evidence that the region supported a complex prehistoric culture. The Marajoara culture flourished on Marajó in the Amazon delta from AD 400 to 1400, developing sophisticated pottery, social stratification, large populations, mound building, and complex social formations such as chiefdoms. Around the time of the Portuguese arrival, the territory of current day Brazil had an estimated indigenous population of 7 million people, mostly semi-nomadic, who subsisted on hunting, fishing, gathering, and migrant agriculture. The population comprised several large indigenous ethnic groups (e.g., the Tupis, Guaranis, Gês, and Arawaks). The Tupi people were subdivided into the Tupiniquins and Tupinambás. Before the arrival of the Europeans, the boundaries between these groups and their subgroups were marked by wars that arose from differences in culture, language and moral beliefs. These wars also involved large-scale military actions on land and water, with cannibalistic rituals on prisoners of war. While heredity had some weight, leadership was a status more won over time than assigned in succession ceremonies and conventions. Slavery among the indigenous groups had a different meaning than it had for Europeans, since it originated from a diverse socioeconomic organization, in which asymmetries were translated into kinship relations. Portuguese colonization Following the 1494 Treaty of Tordesillas, the land now called Brazil was claimed for the Portuguese Empire on 22 April 1500, with the arrival of the Portuguese fleet commanded by Pedro Álvares Cabral. The Portuguese encountered indigenous peoples divided into several ethnic societies, most of whom spoke languages of the Tupi–Guarani family and fought among themselves. Though the first settlement was founded in 1532, colonization effectively began in 1534, when King John III of Portugal divided the territory into the fifteen private and autonomous captaincies. However, the decentralized and unorganized tendencies of the captaincies proved problematic, and in 1549 the Portuguese king restructured them into the Governorate General of Brazil in the city of Salvador, which became the capital of a single and centralized Portuguese colony in South America. In the first two centuries of colonization, Indigenous and European groups lived in constant war, establishing opportunistic alliances in order to gain advantages against each other. By the mid-16th century, cane sugar had become Brazil's most important export, while slaves purchased in Sub-Saharan Africa in the slave market of Western Africa (not only those from Portuguese allies of their colonies in Angola and Mozambique), had become its largest import, to cope with sugarcane plantations, due to increasing international demand for Brazilian sugar. Brazil received more than 2.8 million slaves from Africa between the years 1500 and 1800. By the end of the 17th century, sugarcane exports began to decline and the discovery of gold by bandeirantes in the 1690s would become the new backbone of the colony's economy, fostering a gold rush which attracted thousands of new settlers to Brazil from Portugal and all Portuguese colonies around the world. This increased level of immigration in turn caused some conflicts between newcomers and old settlers. Portuguese expeditions known as bandeiras gradually expanded Brazil's original colonial frontiers in South America to its approximately current borders. In this era other European powers tried to colonize parts of Brazil, in incursions that the Portuguese had to fight, notably the French in Rio during the 1560s, in Maranhão during the 1610s, and the Dutch in Bahia and Pernambuco, during the Dutch–Portuguese War, after the end of Iberian Union. The Portuguese colonial administration in Brazil had two objectives that would ensure colonial order and the monopoly of Portugal's wealthiest and largest colony: to keep under control and eradicate all forms of slave rebellion and resistance, such as the Quilombo of Palmares, and to repress all movements for autonomy or independence, such as the Minas Gerais Conspiracy. Elevation to kingdom In late 1807, Spanish and Napoleonic forces threatened the security of continental Portugal, causing Prince Regent John, in the name of Queen Maria I, to move the royal court from Lisbon to Rio de Janeiro. There they established some of Brazil's first financial institutions, such as its local stock exchanges and its National Bank, additionally ending the Portuguese monopoly on Brazilian trade and opening Brazil's ports to other nations. In 1809, in retaliation for being forced into exile, the Prince Regent ordered the conquest of French Guiana. With the end of the Peninsular War in 1814, the courts of Europe demanded that Queen Maria I and Prince Regent John return to Portugal, deeming it unfit for the head of an ancient European monarchy to reside in a colony. In 1815, to justify continuing to live in Brazil, where the royal court had thrived for six years, the Crown established the United Kingdom of Portugal, Brazil and the Algarves, thus creating a pluricontinental transatlantic monarchic state. However, the leadership in Portugal, resentful of the new status of its larger colony, continued to demand the return of the court to Lisbon (see Liberal Revolution of 1820). In 1821, acceding to the demands of revolutionaries who had taken the city of Porto, John VI departed for Lisbon. There he swore an oath to the new constitution, leaving his son, Prince Pedro de Alcântara, as Regent of the Kingdom of Brazil. Independent empire Tensions between Portuguese and Brazilians increased and the Portuguese Cortes, guided by the new political regime imposed by the Liberal Revolution, tried to re-establish Brazil as a colony. The Brazilians refused to yield, and Prince Pedro decided to stand with them, declaring the country's independence from Portugal on 7 September 1822. A month later, Prince Pedro was declared the first Emperor of Brazil, with the royal title of Dom Pedro I, resulting in the founding of the Empire of Brazil. The Brazilian War of Independence, which had already begun along this process, spread through the northern, northeastern regions and in the Cisplatina province. The last Portuguese soldiers surrendered on 8 March 1824; Portugal officially recognized Brazilian independence on 29 August 1825. On 7 April 1831, worn down by years of administrative turmoil and political dissent with both liberal and conservative sides of politics, including an attempt of republican secession and unreconciled to the way that absolutists in Portugal had given in the succession of King John VI, Pedro I departed for Portugal to reclaim his daughter's crown after abdicating the Brazilian throne in favor of his five-year-old son and heir (Dom Pedro II). As the new Emperor could not exert his constitutional powers until he came of age, a regency was set up by the National Assembly. In the absence of a charismatic figure who could represent a moderate face of power, during this period a series of localized rebellions took place, such as the Cabanagem in Grão-Pará, the Malê Revolt in Salvador, the Balaiada (Maranhão), the Sabinada (Bahia), and the Ragamuffin War, which began in Rio Grande do Sul and was supported by Giuseppe Garibaldi. These emerged from the provinces' dissatisfaction with the central power, coupled with old and latent social tensions peculiar to a vast, slaveholding and newly independent nation state. This period of internal political and social upheaval, which included the Praieira revolt in Pernambuco, was overcome only at the end of the 1840s, years after the end of the regency, which occurred with the premature coronation of Pedro II in 1841. During the last phase of the monarchy, internal political debate centered on the issue of slavery. The Atlantic slave trade was abandoned in 1850, as a result of the British Aberdeen Act and the Eusébio de Queirós Law, but only in May 1888, after a long process of internal mobilization and debate for an ethical and legal dismantling of slavery in the country, was the institution formally abolished with the approval of the Golden Law. The foreign-affairs policies of the monarchy dealt with issues with the countries of the Southern Cone with whom Brazil had borders. Long after the Cisplatine War that resulted in the independence of Uruguay, Brazil won three international wars during the 58-year reign of Pedro II: the Platine War, the Uruguayan War and the devastating Paraguayan War, the largest war effort in Brazilian history. Although there was no desire among the majority of Brazilians to change the country's form of government, on 15 November 1889, in disagreement with the majority of the Imperial Army officers, as well as with rural and financial elites (for different reasons), the monarchy was overthrown by a military coup. A few days later, the national flag was replaced with a new design that included the national motto "Ordem e Progresso", influenced by positivism. 15 November is now Republic Day, a national holiday. Early republic The early republican government was a military dictatorship, with the army dominating affairs both in Rio de Janeiro and in the states. Freedom of the press disappeared and elections were controlled by those in power. Not until 1894, following an economic crisis and a military one, did civilians take power, remaining there until October 1930. If in relation to its foreign policy, the country in this first republican period maintained a relative balance characterized by a success in resolving border disputes with neighboring countries, only broken by the Acre War (1899–1902) and its involvement in World War I (1914–1918), followed by a failed attempt to exert a prominent role in the League of Nations; Internally, from the crisis of Encilhamento and the Navy Revolts, a prolonged cycle of financial, political and social instability began until the 1920s, keeping the country besieged by various rebellions, both civilian and military. Little by little, a cycle of general instability sparked by these crises undermined the regime to such an extent that in the wake of the murder of his running mate, the defeated opposition presidential candidate Getúlio Vargas, supported by most of the military, successfully led the Revolution of 1930. Vargas and the military were supposed to assume power temporarily, but instead closed down Congress, extinguished the Constitution, ruled with emergency powers and replaced the states' governors with his own supporters. In the 1930s, three attempts to remove Vargas and his supporters from power failed. The first was the Constitutionalist Revolution in 1932, led by the São Paulo's oligarchy. The second was a Communist uprising in November 1935, and the last one a putsch attempt by local fascists in May 1938. The 1935 uprising created a security crisis in which Congress transferred more power to the executive branch. The 1937 coup d'état resulted in the cancellation of the 1938 election and formalized Vargas as dictator, beginning the Estado Novo era. During this period, government brutality and censorship of the press increased. During World War II, Brazil remained neutral until August 1942, when the country suffered retaliation by Nazi Germany and Fascist Italy in a strategic dispute over the South Atlantic, and, therefore, entered the war on the allied side. In addition to its participation in the battle of the Atlantic, Brazil also sent an expeditionary force to fight in the Italian campaign. With the Allied victory in 1945 and the end of the fascist regimes in Europe, Vargas's position became unsustainable, and he was swiftly overthrown in another military coup, with democracy "reinstated" by the same army that had ended it 15 years earlier. Vargas committed suicide in August 1954 amid a political crisis, after having returned to power by election in 1950. Contemporary era Several brief interim governments followed Vargas's suicide. Juscelino Kubitschek became president in 1956 and assumed a conciliatory posture towards the political opposition that allowed him to govern without major crises. The economy and industrial sector grew remarkably, but his greatest achievement was the construction of the new capital city of Brasília, inaugurated in 1960. Kubitschek's successor, Jânio Quadros, resigned in 1961 less than a year after taking office. His vice-president, João Goulart, assumed the presidency, but aroused strong political opposition and was deposed in April 1964 by a coup that resulted in a military dictatorship. The new regime was intended to be transitory but gradually closed in on itself and became a full dictatorship with the promulgation of the Fifth Institutional Act in 1968. Oppression was not limited to those who resorted to guerrilla tactics to fight the regime, but also reached institutional opponents, artists, journalists and other members of civil society, inside and outside the country through the infamous "Operation Condor". Like other brutal authoritarian regimes, due to an economic boom, known as the "economic miracle", the regime reached a peak in popularity in the early 1970s. Slowly, however, the wear and tear of years of dictatorial power that had not slowed the repression, even after the defeat of the leftist guerrillas. The inability to deal with the economic crises of the period and popular pressure made an opening policy inevitable, which from the regime side was led by Generals Ernesto Geisel and Golbery do Couto e Silva. With the enactment of the Amnesty Law in 1979, Brazil began a slow return to democracy, which was completed during the 1980s. Civilians returned to power in 1985 when José Sarney assumed the presidency. He became unpopular during his tenure through failure to control the economic crisis and hyperinflation he inherited from the military regime. Sarney's unsuccessful government led to the election in 1989 of the almost-unknown Fernando Collor, who was subsequently impeached by the National Congress in 1992. Collor was succeeded by his vice-president, Itamar Franco, who appointed Fernando Henrique Cardoso Minister of Finance. In 1994, Cardoso produced a highly successful Plano Real, that, after decades of failed economic plans made by previous governments attempting to curb hyperinflation, finally stabilized the Brazilian economy. Cardoso won the 1994 election, and again in 1998. The peaceful transition of power from Cardoso to his main opposition leader, Luiz Inácio Lula da Silva (elected in 2002 and re-elected in 2006), was seen as proof that Brazil had achieved a long-sought political stability. However, sparked by indignation and frustrations accumulated over decades from corruption, police brutality, inefficiencies of the political establishment and public service, numerous peaceful protests erupted in Brazil from the middle of first term of Dilma Rousseff, who had succeeded Lula after winning election in 2010 and again in 2014 by narrow margins. Rousseff was impeached by the Brazilian Congress in 2016, halfway into her second term, and replaced by her Vice-president Michel Temer, who assumed full presidential powers after Rousseff's impeachment was accepted on 31 August. Large street protests for and against her took place during the impeachment process. The charges against her were fueled by political and economic crises along with evidence of involvement with politicians from all the primary political parties. In 2017, the Supreme Court requested the investigation of 71 Brazilian lawmakers and nine ministers of President Michel Temer's cabinet who were allegedly linked to the Petrobras corruption scandal. President Temer himself was also accused of corruption. According to a 2018 poll, 62% of the population said that corruption was Brazil's biggest problem. In the fiercely disputed 2018 elections, the controversial conservative candidate Jair Bolsonaro of the Social Liberal Party (PSL) was elected president, winning in the second round Fernando Haddad, of the Workers Party (PT), with the support of 55.13% of the valid votes. In the early 2020s, Brazil became one of the hardest hit countries during the COVID-19 pandemic, receiving the second-highest death toll worldwide after the United States. In May 2021, Luiz Inácio Lula da Silva stated that he would run for a third term in the 2022 Brazilian general election against Bolsonaro. On october 2022, Lula was in first place in first round, with 48.43% of the support from the electorate, and received 50.90% of the votes in the second round. On 8 January 2023, a week after Lula's inauguration, a mob of Bolsonaro's supporters attacked Brazil's federal government buildings in the capital, Brasília, after several weeks of unrest. Geography Brazil occupies a large area along the eastern coast of South America and includes much of the continent's interior, sharing land borders with Uruguay to the south; Argentina and Paraguay to the southwest; Bolivia and Peru to the west; Colombia to the northwest; and Venezuela, Guyana, Suriname and France (French overseas region of French Guiana) to the north. It shares a border with every South American country except Ecuador and Chile. The brazilian territory also encompasses a number of oceanic archipelagos, such as Fernando de Noronha, Rocas Atoll, Saint Peter and Paul Rocks, and Trindade and Martim Vaz. Its size, relief, climate, and natural resources make Brazil geographically diverse. Including its Atlantic islands, Brazil lies between latitudes 6°N and 34°S, and longitudes 28° and 74°W. Brazil is the fifth largest country in the world, and third largest in the Americas, with a total area of , including of water. North to South, Brazil is also the longest country in the world, spanning 4,395 km (2,731 mi) from north to south, and the only country in the world that has the equator and the Tropic of Capricorn running through it. It spans four time zones; from UTC−5 comprising the state of Acre and the westernmost portion of Amazonas, to UTC−4 in the western states, to UTC−3 in the eastern states (the national time) and UTC−2 in the Atlantic islands. Climate The climate of Brazil comprises a wide range of weather conditions across a large area and varied topography, but most of the country is tropical. According to the Köppen system, Brazil hosts six major climatic subtypes: desert, equatorial, tropical, semiarid, oceanic and subtropical. The different climatic conditions produce environments ranging from equatorial rainforests in the north and semiarid deserts in the northeast, to temperate coniferous forests in the south and tropical savannas in central Brazil. Many regions have starkly different microclimates. An equatorial climate characterizes much of northern Brazil. There is no real dry season, but there are some variations in the period of the year when most rain falls. Temperatures average , with more significant temperature variation between night and day than between seasons. Over central Brazil rainfall is more seasonal, characteristic of a savanna climate. This region is as extensive as the Amazon basin but has a very different climate as it lies farther south at a higher altitude. In the interior northeast, seasonal rainfall is even more extreme. South of Bahia, near the coasts, and more southerly most of the state of São Paulo, the distribution of rainfall changes, with rain falling throughout the year. The south enjoys subtropical conditions, with cool winters and average annual temperatures not exceeding ; winter frosts and snowfall are not rare in the highest areas. The semiarid climatic region generally receives less than of rain, most of which generally falls in a period of three to five months of the year and occasionally less than this, creating long periods of drought. Brazil's 1877–78 Grande Seca (Great Drought), the worst in Brazil's history, caused approximately half a million deaths. A similarly devastating drought occurred in 1915. In 2020 the government of Brazil pledged to reduce its annual greenhouse gases emissions by 43% by 2030. It also set as indicative target of reaching carbon neutrality by 2060 if the country gets 10 billion dollars per year. Topography and hydrography Brazilian topography is also diverse and includes hills, mountains, plains, highlands, and scrublands. Much of the terrain lies between and in elevation. The main upland area occupies most of the southern half of the country. The northwestern parts of the plateau consist of broad, rolling terrain broken by low, rounded hills. The southeastern section is more rugged, with a complex mass of ridges and mountain ranges reaching elevations of up to . These ranges include the Mantiqueira and Espinhaço mountains and the Serra do Mar. In the north, the Guiana Highlands form a major drainage divide, separating rivers that flow south into the Amazon Basin from rivers that empty into the Orinoco River system, in Venezuela, to the north. The highest point in Brazil is the Pico da Neblina at , and the lowest is the Atlantic Ocean. Brazil has a dense and complex system of rivers, one of the world's most extensive, with eight major drainage basins, all of which drain into the Atlantic. Major rivers include the Amazon (the world's second-longest river and the largest in terms of volume of water), the Paraná and its major tributary the Iguaçu (which includes the Iguazu Falls), the Negro, São Francisco, Xingu, Madeira and Tapajós rivers. Biodiversity and conservation The wildlife of Brazil comprises all naturally occurring animals, plants, and fungi in the South American country. Home to 60% of the Amazon rainforest, which accounts for approximately one-tenth of all species in the world, Brazil is considered to have the greatest biodiversity of any country on the planet, containing over 70% of all animal and plant species catalogued. Brazil has the most known species of plants (55,000), freshwater fish (3,000), and mammals (over 689). It also ranks third on the list of countries with the most bird species (1,832) and second with the most reptile species (744). The number of fungal species is unknown but is large. Brazil is second only to Indonesia as the country with the most endemic species. Brazil's large territory comprises different ecosystems, such as the Amazon rainforest, recognized as having the greatest biological diversity in the world, with the Atlantic Forest and the Cerrado, sustaining the greatest biodiversity. In the south, the Araucaria moist forests grow under temperate conditions. The rich wildlife of Brazil reflects the variety of natural habitats. Scientists estimate that the total number of plant and animal species in Brazil could approach four million, mostly invertebrates. Larger mammals include carnivores pumas, jaguars, ocelots, rare bush dogs, and foxes, and herbivores peccaries, tapirs, anteaters, sloths, opossums, and armadillos. Deer are plentiful in the south, and many species of New World monkeys are found in the northern rain forests. More than one-fifth of the Amazon rainforest in Brazil has been completely destroyed, and more than 70 mammals are endangered. The threat of extinction comes from several sources, including deforestation and poaching. Extinction is even more problematic in the Atlantic Forest, where nearly 93% of the forest has been cleared. Of the 202 endangered animals in Brazil, 171 are in the Atlantic Forest. The Amazon rainforest has been under direct threat of deforestation since the 1970s because of rapid economic and demographic expansion. Extensive legal and illegal logging destroy forests the size of a small country per year, and with it a diverse series of species through habitat destruction and habitat fragmentation. Since 1970, over of the Amazon rainforest have been cleared by logging. In 2017, preserved native vegetation occupies 61% of the Brazilian territory. Agriculture occupied only 8% of the national territory and pastures 19.7%. In terms of comparison, in 2019, although 43% of the entire European continent has forests, only 3% of the total forest area in Europe is of native forest. Brazil has a strong interest in conservation as its agriculture sector directly depends on its forests. Government and politics The form of government is a democratic federative republic, with a presidential system. The president is both head of state and head of government of the Union and is elected for a four-year term, with the possibility of re-election for a second successive term. The current president is Luiz Inácio Lula da Silva. The President appoints the Ministers of State, who assist in government. Legislative houses in each political entity are the main source of law in Brazil. The National Congress is the Federation's bicameral legislature, consisting of the Chamber of Deputies and the Federal Senate. Judiciary authorities exercise jurisdictional duties almost exclusively. In 2021, the Economist Intelligence Unit's Democracy Index categorized Brazil as a "flawed democracy", ranking 46th in the report, and Freedom House classified it as a free country at Freedom in the World report. The political-administrative organization of the Federative Republic of Brazil comprises the Union, the states, the Federal District, and the municipalities. The Union, the states, the Federal District, and the municipalities, are the "spheres of government". The federation is set on five fundamental principles: sovereignty, citizenship, dignity of human beings, the social values of labor and freedom of enterprise, and political pluralism. The classic tripartite branches of government (executive, legislative and judicial under a checks and balances system) are formally established by the Constitution. The executive and legislative are organized independently in all three spheres of government, while the judiciary is organized only at the federal and state and Federal District spheres. All members of the executive and legislative branches are directly elected. For most of its democratic history, Brazil has had a multi-party system, with proportional representation. Voting is compulsory for the literate between 18 and 70 years old and optional for illiterates and those between 16 and 18 or beyond 70. The country has more than 40 active political parties. Fifteen political parties are represented in Congress. It is common for politicians to switch parties, and thus the proportion of congressional seats held by particular parties changes regularly. Law Brazilian law is based on the civil law legal system and civil law concepts prevail over common law practice. Most of Brazilian law is codified, although non-codified statutes also represent a substantial part, playing a complementary role. Court decisions set out interpretive guidelines; however, they are seldom binding on other specific cases. Doctrinal works and the works of academic jurists have strong influence in law creation and in law cases. Judges and other judicial officials are appointed after passing entry exams. The legal system is based on the Federal Constitution, promulgated on 5 October 1988, and the fundamental law of Brazil. All other legislation and court decisions must conform to its rules. , there have been 124 amendments. The highest court is the Supreme Federal Court. States have their own constitutions, which must not contradict the Federal Constitution. Municipalities and the Federal District have "organic laws" (), which act in a similar way to constitutions. Legislative entities are the main source of statutes, although in certain matters judiciary and executive bodies may enact legal norms. Jurisdiction is administered by the judiciary entities, although in rare situations the Federal Constitution allows the Federal Senate to pass on legal judgments. There are also specialized military, labor, and electoral courts. Military The armed forces of Brazil are the largest in Latin America by active personnel and the largest in terms of military equipment. The country was considered the 9th largest military power on the planet in 2021. It consists of the Brazilian Army (including the Army Aviation Command), the Brazilian Navy (including the Marine Corps and Naval Aviation), and the Brazilian Air Force. Brazil's conscription policy gives it one of the world's largest military forces, estimated at more than 1.6 million reservists annually. Numbering close to 236,000 active personnel, the Brazilian Army has the largest number of armored vehicles in South America, including armored transports and tanks. The states' Military Police and the Military Firefighters Corps are described as an ancillary forces of the Army by the constitution, but are under the control of each state's governor. Brazil's navy once operated some of the most powerful warships in the world with the two dreadnoughts, sparking a naval arms race between Argentina, Brazil, and Chile. Today, it is a green water force and has a group of specialized elite in retaking ships and naval facilities, GRUMEC, unit specially trained to protect Brazilian oil platforms along its coast. , it is the only navy in Latin America that operates an helicopter carrier, NAM Atlântico, and one of twelve navies in the world to operate or have one under construction. The Air Force is the largest in Latin America and has about 700 crewed aircraft in service and effective about 67,000 personnel. Foreign policy Brazil's international relations are based on Article 4 of the Federal Constitution, which establishes non-intervention, self-determination, international cooperation and the peaceful settlement of conflicts as the guiding principles of Brazil's relationship with other countries and multilateral organizations. According to the Constitution, the President has ultimate authority over foreign policy, while the Congress is tasked with reviewing and considering all diplomatic nominations and international treaties, as well as legislation relating to Brazilian foreign policy. Brazil's foreign policy is a by-product of the country's position as a regional power in Latin America, a leader among developing countries, and an emerging world power. Brazilian foreign policy has generally been based on the principles of multilateralism, peaceful dispute settlement, and non-intervention in the affairs of other countries. Brazil is a founding member state of the Community of Portuguese Language Countries (CPLP), also known as the Lusophone Commonwealth, an international organization and political association of Lusophone nations. An increasingly well-developed tool of Brazil's foreign policy is providing aid as a donor to other developing countries. Brazil does not just use its growing economic strength to provide financial aid, but it also provides high levels of expertise and most importantly of all, a quiet non-confrontational diplomacy to improve governance levels. Total aid is estimated to be around $1 billion per year, which includes. In addition, Brazil already managed a peacekeeping mission in Haiti ($350 million) and makes in-kind contributions to the World Food Programme ($300 million). This is in addition to humanitarian assistance and contributions to multilateral development agencies. The scale of this aid places it on par with China and India. The Brazilian South-South aid has been described as a "global model in waiting". Law enforcement and crime In Brazil, the Constitution establishes six different police agencies for law enforcement: Federal Police Department, Federal Highway Police, Federal Railroad Police, Federal, District and State Penal Police (included by the Constitutional Amendment No. 104, of 2019), Military Police and Civil Police. Of these, the first three are affiliated with federal authorities, the last two are subordinate to state governments and the Penal Police can be subordinated to the federal or state/district government. All police forces are the responsibility of the executive branch of any of the federal or state powers. The National Public Security Force also can act in public disorder situations arising anywhere in the country. The country still has above-average levels of violent crime and particularly high levels of gun violence and homicide. In 2012, the World Health Organization (WHO) estimated the number of 32 deaths per 100,000 inhabitants, one of the highest rates of homicide of the world. The number considered tolerable by the WHO is about 10 homicides per 100,000 inhabitants. In 2018, Brazil had a record 63,880 murders. However, there are differences between the crime rates in the Brazilian states. While in São Paulo the homicide rate registered in 2013 was 10.8 deaths per 100,000 inhabitants, in Alagoas it was 64.7 homicides per 100,000 inhabitants. Brazil also has high levels of incarceration and the third largest prison population in the world (behind only China and the United States), with an estimated total of approximately 700,000 prisoners around the country (June 2014), an increase of about 300% compared to the index registered in 1992. The high number of prisoners eventually overloaded the Brazilian prison system, leading to a shortfall of about 200,000 accommodations. Human rights LGBT rights are generally supported within Brazil, and same-sex marriage has been fully recognised since 2013. However, police violence and gender-based discrimination remain prevalent throughout the nation. Brazil has one of the highest Gini coefficient rankings in Latin America. Political subdivisions Brazil is a federation composed of 26 states, one federal district, and the 5,570 municipalities. States have autonomous administrations, collect their own taxes and receive a share of taxes collected by the Federal government. They have a governor and a unicameral legislative body elected directly by their voters. They also have independent Courts of Law for common justice. Despite this, states have much less autonomy to create their own laws than in other federal states such as the United States. For example, criminal and civil laws can be voted by only the federal bicameral Congress and are uniform throughout the country. The states and the federal district are grouped into regions: Northern, Northeast, Central-West, Southeast and Southern. The Brazilian regions are merely geographical, not political or administrative divisions, and they do not have any specific form of government. Although defined by law, Brazilian regions serve mainly statistical purposes, and also to define the distribution of federal funds in development projects. Municipalities, as the states, have autonomous administrations, collect their own taxes and receive a share of taxes collected by the federal and state government. Each has an elected mayor and legislative body, but no separate Court of Law. Indeed, a Court of Law organized by the state can encompass many municipalities in a single justice administrative division called comarca (county). Brazil's constitution also provides for the creation of federal territories, which are administrative divisions directly controlled by the federal government. However, there are currently no federal territories in the country, as the 1988 Constitution abolished the last three: Amapá and Roraima (which gained statehood status) and Fernando de Noronha, which became a state district of Pernambuco. Economy Brazil's upper-middle income mixed market economy is rich in natural resources. It has the largest national economy in Latin America, the tenth-largest economy in the world by nominal GDP, and the ninth-largest by PPP. After rapid growth in preceding decades, the country entered an ongoing recession in 2014 amid a political corruption scandal and nationwide protests. A developing country, Brazil has a labor force of roughly 100 million, which is the world's fifth-largest; with a high unemployment rate of 14.4% . Its foreign exchange reserves are the tenth-highest in the world. The B3 in São Paulo is the largest stock exchange of Latin America by market capitalization. In regards to poverty, about 1.9% of the total population lives at $2.15 a day, while about 19% live at $6.85 a day. Brazil's economy suffers from endemic corruption and high income inequality. The Brazilian real is the national currency. Brazil's diversified economy includes agriculture, industry, and a wide range of services. The large service sector accounts for about 72.7% of total GDP, followed by the industrial sector (20.7%), while the agriculture sector is by far the smallest, making up 6.6% of total GDP. Brazil is one of the largest producers of various agricultural commodities, and also has a large cooperative sector that provides 50% of the food in the country. It has been the world's largest producer of coffee for the last 150 years. Brazil is the world's largest producer of sugarcane, soy, coffee and orange; is one of the top 5 producers of maize, cotton, lemon, tobacco, pineapple, banana, beans, coconut, watermelon and papaya; and is one of the top 10 world producers of cocoa, cashew, mango, rice, tomato, sorghum, tangerine, avocado, persimmon, and guava, among others. Regarding livestock, it is one of the 5 largest producers of chicken meat, beef, pork and cow's milk in the world. In the mining sector, Brazil is among the largest producers of iron ore, copper, gold, bauxite, manganese, tin, niobium, and nickel. In terms of precious stones, Brazil is the world's largest producer of amethyst, topaz, agate and one of the main producers of tourmaline, emerald, aquamarine, garnet and opal. The country is a major exporter of soy, iron ore, pulp (cellulose), maize, beef, chicken meat, soybean meal, sugar, coffee, tobacco, cotton, orange juice, footwear, airplanes, cars, vehicle parts, gold, ethanol, semi-finished iron, among other products. Brazil is the world's 24th-largest exporter and 26th-largest importer . China is its largest trading partner, accounting for 32% of the total trade. Other large trading partners include the United States, Argentina, the Netherlands and Canada. Its automotive industry is the eighth-largest in the world. In the food industry, Brazil was the second-largest exporter of processed foods in the world in 2019. The country was the second-largest producer of pulp in the world and the eighth-largest producer of paper in 2016. In the footwear industry, Brazil was the fourth-largest producer in 2019. It was also the ninth-largest producer of steel in the world. In 2018, the chemical industry of Brazil was the eighth-largest in the world. Although, it was among the five largest world producers in 2013, Brazil's textile industry is very little integrated into world trade. The tertiary sector (trade and services) represented 75.8% of the country's GDP in 2018, according to the IBGE. The service sector was responsible for 60% of GDP and trade for 13%. It covers a wide range of activities: commerce, accommodation and catering, transport, communications, financial services, real estate activities and services provided to businesses, public administration (urban cleaning, sanitation, etc.) and other services such as education, social and health services, research and development, sports activities, etc., since it consists of activities complementary to other sectors. Micro and small businesses represent 30% of the country's GDP. In the commercial sector, for example, they represent 53% of the GDP within the activities of the sector. Tourism Tourism in Brazil is a growing sector and key to the economy of several regions of the country. The country had 6.36 million visitors in 2015, ranking in terms of the international tourist arrivals as the main destination in South America and second in Latin America after Mexico. Revenues from international tourists reached billion in 2010, showing a recovery from the 2008–2009 economic crisis. Historical records of 5.4 million visitors and billion in receipts were reached in 2011. In the list of world tourist destinations, in 2018, Brazil was the 48th most visited country, with 6.6 million tourists (and revenues of 5.9 billion dollars). Natural areas are its most popular tourism product, a combination of ecotourism with leisure and recreation, mainly sun and beach, and adventure travel, as well as cultural tourism. Among the most popular destinations are the Amazon Rainforest, beaches and dunes in the Northeast Region, the Pantanal in the Center-West Region, beaches at Rio de Janeiro and Santa Catarina, cultural tourism in Minas Gerais and business trips to São Paulo. In terms of the 2015 Travel and Tourism Competitiveness Index (TTCI), which is a measurement of the factors that make it attractive to develop business in the travel and tourism industry of individual countries, Brazil ranked in the 28th place at the world's level, third in the Americas, after Canada and United States. Domestic tourism is a key market segment for the tourism industry in Brazil. In 2005, 51 million Brazilian nationals made ten times more trips than foreign tourists and spent five times more money than their international counterparts. The main destination states in 2005 were São Paulo (27.7%), Minas Gerais (10.8%), Rio de Janeiro (8.4%), Bahia (7.4%), and Santa Catarina (7.2%). The top three states by trip origin were São Paulo (35.7%), Minas Gerais (13.6%). In terms of tourism revenues, the top earners by state were São Paulo (16.4%) and Bahia (11.7%). For 2005, the three main trip purposes were visiting friends and family (53.1%), sun and beach (40.8%), and cultural tourism (12.5%). Science and technology Technological research in Brazil is largely carried out in public universities and research institutes, with the majority of funding for basic research coming from various government agencies. Brazil's most esteemed technological hubs are the Oswaldo Cruz Institute, the Butantan Institute, the Air Force's Aerospace Technical Center, the Brazilian Agricultural Research Corporation and the National Institute for Space Research. The Brazilian Space Agency has the most advanced space program in Latin America, with significant resources to launch vehicles, and manufacture of satellites. Owner of relative technological sophistication, the country develops submarines, aircraft, as well as being involved in space research, having a Vehicle Launch Center Light and being the only country in the Southern Hemisphere the integrate team building International Space Station (ISS). The country is also a pioneer in the search for oil in deep water, from where it extracts 73% of its reserves. Uranium is enriched at the Resende Nuclear Fuel Factory, mostly for research purposes (as Brazil obtains 88% of its electricity from hydroelectricity) and the country's first nuclear submarine is expected to be launched in 2029. Brazil is one of the three countries in Latin America with an operational Synchrotron Laboratory, a research facility on physics, chemistry, material science and life sciences, and Brazil is the only Latin American country to have a semiconductor company with its own fabrication plant, the CEITEC. According to the Global Information Technology Report 2009–2010 of the World Economic Forum, Brazil is the world's 61st largest developer of information technology. Brazil was ranked 49th in the Global Innovation Index in 2023, up from 66th in 2019. Among the most renowned Brazilian inventors are priests Bartolomeu de Gusmão, Landell de Moura and Francisco João de Azevedo, besides Alberto Santos-Dumont, Evaristo Conrado Engelberg, Manuel Dias de Abreu, Andreas Pavel and Nélio José Nicolai. Brazilian science is represented by the likes of César Lattes (Brazilian physicist Pathfinder of Pi Meson), Mário Schenberg (considered the greatest theoretical physicist of Brazil), José Leite Lopes (only Brazilian physicist holder of the UNESCO Science Prize), Artur Ávila (the first Latin American winner of the Fields Medal) and Fritz Müller (pioneer in factual support of the theory of evolution by Charles Darwin). Energy Brazil is the world's ninth largest energy consumer. Much of its energy comes from renewable sources, particularly hydroelectricity and ethanol; the Itaipu Dam is the world's largest hydroelectric plant by energy generation, and the country has other large plants like Belo Monte and Tucuruí. The first car with an ethanol engine was produced in 1978 and the first airplane engine running on ethanol in 2005. At the end of 2021 Brazil was the 2nd country in the world in terms of installed hydroelectric power (109.4 GW) and biomass (15.8 GW), the 7th country in the world in terms of installed wind power (21.1 GW) and the 14th country in the world in terms of installed solar power (13.0 GW) – on track to also become one of the top 10 in the world in solar energy. At the end of 2021, Brazil was the 4th largest producer of wind energy in the world (72 TWh), behind only China, the United States and Germany, and the 11th largest producer of solar energy in the world (16.8 TWh). The main characteristic of the Brazilian energy matrix is that it is much more renewable than that of the world. While in 2019 the world matrix was only 14% made up of renewable energy, Brazil's was at 45%. Petroleum and oil products made up 34.3% of the matrix; sugar cane derivatives, 18%; hydraulic energy, 12.4%; natural gas, 12.2%; firewood and charcoal, 8.8%; varied renewable energies, 7%; mineral coal, 5.3%; nuclear, 1.4%, and other non-renewable energies, 0.6%. In the electric energy matrix, the difference between Brazil and the world is even greater: while the world only had 25% of renewable electric energy in 2019, Brazil had 83%. The Brazilian electric matrix was composed of: hydraulic energy, 64.9%; biomass, 8.4%; wind energy, 8.6%; solar energy, 1%; natural gas, 9.3%; oil products, 2%; nuclear, 2.5%; coal and derivatives, 3.3%. Brazil has the largest electricity sector in Latin America. Its capacity at the end of 2021 was 181,532 MW. As for oil, the Brazilian government has embarked on a program over the decades to reduce dependence on imported oil, which previously accounted for more than 70% of the country's oil needs. Brazil became self-sufficient in oil in 2006–2007. In 2021, the country closed the year as the 7th oil producer in the world, with an average of close to three million barrels per day, becoming an exporter of the product. Transportation Brazilian roads are the primary carriers of freight and passenger traffic. The road system totaled in 2019. The total of paved roads increased from in 1967 to in 2018. Brazil's railway system has been declining since 1945, when emphasis shifted to highway construction. The country's total railway track length was in 2015, as compared with in 1970, making it the ninth largest network in the world. Most of the railway system belonged to the Federal Railroad Network Corporation (RFFSA), which was privatized in 2007. The São Paulo Metro was the first underground transit system in Brazil, which began operating on 14 September 1974. There are about 2,500 airports in Brazil, including landing fields: the second largest number in the world, after the United States. São Paulo–Guarulhos International Airport, near São Paulo, is the largest and busiest airport with nearly 20 million passengers annually, while handling the vast majority of commercial traffic for the country. For freight transport waterways are of importance, e.g. the industrial zones of Manaus can be reached only by means of the Solimões–Amazonas waterway ( in length, with a minimum depth of ). The country also has of waterways. Coastal shipping links widely separated parts of the country. Bolivia and Paraguay have been given free ports at Santos. Of the 36 deep-water ports, Santos, Itajaí, Rio Grande, Paranaguá, Rio de Janeiro, Sepetiba, Vitória, Suape, Manaus, and São Francisco do Sul are the most important. Bulk carriers have to wait up to 18 days before being serviced, container ships 36.3 hours on average. Demographics The population of Brazil, as recorded by the 2008 PNAD, was approximately 190 million (), with a ratio of men to women of 0.95:1 and 83.75% of the population defined as urban. The population is heavily concentrated in the Southeastern (79.8 million inhabitants) and Northeastern (53.5 million inhabitants) regions, while the two most extensive regions, the Center-West and the North, which together make up 64.12% of the Brazilian territory, have a total of only 29.1 million inhabitants. The first census in Brazil was carried out in 1872 and recorded a population of 9,930,478. From 1880 to 1930, 4 million Europeans arrived. Brazil's population increased significantly between 1940 and 1970, because of a decline in the mortality rate, even though the birth rate underwent a slight decline. In the 1940s the annual population growth rate was 2.4%, rising to 3.0% in the 1950s and remaining at 2.9% in the 1960s, as life expectancy rose from 44 to 54 years and to 72.6 years in 2007. It has been steadily falling since the 1960s, from 3.04% per year between 1950 and 1960 to 1.05% in 2008 and is expected to fall to a negative value of –0.29% by 2050 thus completing the demographic transition. In 2008, the illiteracy rate was 11.48%. Race and ethnicity According to the National Research by Household Sample (PNAD) of 2022, 45.3% of the population (about 91 million) described themselves as Pardo, 43.8% (about 88 million) as White, 10.6% (about 21 million) as Black, 1.1% (about 2 million) as East Asian (officially called yellow or amarela) and 0.8% (about 1 million) as Amerindian (officially called indígena, Indigenous), while 0.07% (about 130 thousand) did not declare their race. Since the arrival of the Portuguese in 1500, considerable genetic mixing between Amerindians, Europeans, and Africans has taken place in all regions of the country (with European ancestry being dominant nationwide according to the vast majority of all autosomal studies undertaken covering the entire population, accounting for between 65% and 77%). From the 19th century, Brazil opened its borders to immigration. About five million people from over 60 countries migrated to Brazil between 1808 and 1972, most of them of Portuguese, Italian, Spanish, German, Ukrainian, Polish, Jewish, Armenian, Russian, Chinese, Japanese, and Arab origin. Brazil has the second largest Jewish community in Latin America making up 0.06% of its population. Brazil also has the largest Arab (or Arab ancestry) community in the world outside the Arab world, with 15–20 million people. Brazilian society is more markedly divided by social class lines, although a high income disparity is found between race groups, so racism and classism often overlap. The brown population (officially called pardo in Portuguese, also colloquially moreno) is a broad category that includes caboclos (assimilated Amerindians in general, and descendants of Whites and Natives), mulatos (descendants of primarily Whites and Afro-Brazilians) and cafuzos (descendants of Afro-Brazilians and Natives). Higher percents of Blacks, mulattoes and tri-racials can be found in the eastern coast of the Northeastern region from Bahia to Paraíba and also in northern Maranhão, southern Minas Gerais and in eastern Rio de Janeiro. People of considerable Amerindian ancestry form the majority of the population in the Northern, Northeastern and Center-Western regions. In 2007, the National Indian Foundation estimated that Brazil has 67 different uncontacted tribes, up from their estimate of 40 in 2005. Brazil is believed to have the largest number of uncontacted peoples in the world. Religion Christianity is the country's predominant faith, with Roman Catholicism being its largest denomination. Brazil has the world's largest Catholic population. According to the 2010 Demographic Census (the PNAD survey does not inquire about religion), 64.63% of the population followed Roman Catholicism; 22.2% Protestantism; 2.0% Kardecist spiritism; 3.2% other religions, undeclared or undetermined; while 8.0% had no religion. Religion in Brazil was formed from the meeting of the Catholic Church with the religious traditions of enslaved African peoples and indigenous peoples. This confluence of faiths during the Portuguese colonization of Brazil led to the development of a diverse array of syncretistic practices within the overarching umbrella of Brazilian Catholic Church, characterized by traditional Portuguese festivities, Religious pluralism increased during the 20th century, and the Protestant community has grown to include over 22% of the population. The most common Protestant denominations are Evangelical Pentecostal ones. Other Protestant branches with a notable presence in the country include the Baptists, Seventh-day Adventists, Lutherans and the Reformed tradition. In recent decades, Protestantism, particularly in forms of Pentecostalism and Evangelicalism, has spread in Brazil, while the proportion of Catholics has dropped significantly. After Protestantism, individuals professing no religion are also a significant group, exceeding 8% of the population as of the 2010 census. The cities of Boa Vista, Salvador, and Porto Velho have the greatest proportion of Irreligious residents in Brazil. Teresina, Fortaleza, and Florianópolis were the most Roman Catholic in the country. Greater Rio de Janeiro, not including the city proper, is the most irreligious and least Roman Catholic Brazilian periphery, while Greater Porto Alegre and Greater Fortaleza are on the opposite sides of the lists, respectively. In October 2009, the Brazilian Senate approved and enacted by the President of Brazil in February 2010, an agreement with the Vatican, in which the Legal Statute of the Catholic Church in Brazil is recognized. Health The Brazilian public health system, the Unified Health System (Sistema Único de Saúde – SUS), is managed and provided by all levels of government, being the largest system of this type in the world. On the other hand, private healthcare systems play a complementary role. Public health services are universal and offered to all citizens of the country for free. However, the construction and maintenance of health centers and hospitals are financed by taxes, and the country spends about 9% of its GDP on expenditures in the area. In 2012, Brazil had 1.85 doctors and 2.3 hospital beds for every 1,000 inhabitants. Despite all the progress made since the creation of the universal health care system in 1988, there are still several public health problems in Brazil. In 2006, the main points to be solved were the high infant (2.51%) and maternal mortality rates (73.1 deaths per 1000 births). The number of deaths from noncommunicable diseases, such as cardiovascular diseases (151.7 deaths per 100,000 inhabitants) and cancer (72.7 deaths per 100,000 inhabitants), also has a considerable impact on the health of the Brazilian population. Finally, external but preventable factors such as car accidents, violence and suicide caused 14.9% of all deaths in the country. The Brazilian health system was ranked 125th among the 191 countries evaluated by the World Health Organization (WHO) in 2000. Education The Federal Constitution and the Law of Guidelines and Bases of National Education determine that the Union, the states, the Federal District, and the municipalities must manage and organize their respective education systems. Each of these public educational systems is responsible for its own maintenance, which manages funds as well as the mechanisms and funding sources. The constitution reserves 25% of the state budget and 18% of federal taxes and municipal taxes for education. According to the IBGE, in 2019, the literacy rate of the population was 93.4%, meaning that 11.3 million (6.6% of population) people are still illiterate in the country, with some states like Rio de Janeiro and Santa Catarina reaching around 97% of literacy rate; functional illiteracy has reached 21.6% of the population. Illiteracy is higher in the Northeast, where 13.87% of the population is illiterate, while the South, has 3.3% of its population illiterate. Brazil's private institutions tend to be more exclusive and offer better quality education, so many high-income families send their children there. The result is a segregated educational system that reflects extreme income disparities and reinforces social inequality. However, efforts to change this are making impacts. The University of São Paulo is the second best university in Latin America, according to recent 2019 QS World University Rankings. Of the top 20 Latin American universities, eight are Brazilian. Most of them are public. Attending an institution of higher education is required by Law of Guidelines and Bases of Education. Kindergarten, elementary and medium education are required of all students. Language The official language of Brazil is Portuguese (Article 13 of the Constitution of the Federal Republic of Brazil), which almost all of the population speaks and is virtually the only language used in newspapers, radio, television, and for business and administrative purposes. Brazil is the only Portuguese-speaking nation in the Americas, making the language an important part of Brazilian national identity and giving it a national culture distinct from those of its Spanish-speaking neighbors. Brazilian Portuguese has had its own development, mostly similar to 16th-century Central and Southern dialects of European Portuguese (despite a very substantial number of Portuguese colonial settlers, and more recent immigrants, coming from Northern regions, and in minor degree Portuguese Macaronesia), with a few influences from the Amerindian and African languages, especially West African and Bantu restricted to the vocabulary only. As a result, the language is somewhat different, mostly in phonology, from the language of Portugal and other Portuguese-speaking countries (the dialects of the other countries, partly because of the more recent end of Portuguese colonialism in these regions, have a closer connection to contemporary European Portuguese). These differences are comparable to those between American and British English. The 2002 sign language law requires government authorities and public agencies to accept and provide information in Língua Brasileira dos Sinais or "LIBRAS", the Brazilian Sign Language, while a 2005 presidential edict extends this to require teaching of the language as a part of the education and speech and language pathology curricula. LIBRAS teachers, instructors and translators are recognized professionals. Schools and health services must provide access ("inclusion") to deaf people. Minority languages are spoken throughout the nation. One hundred and eighty Amerindian languages are spoken in remote areas and a significant number of other languages are spoken by immigrants and their descendants. In the municipality of São Gabriel da Cachoeira, Nheengatu (a currently endangered South American creole language – or an 'anti-creole', according to some linguists – with mostly Indigenous Brazilian languages lexicon and Portuguese-based grammar that, together with its southern relative língua geral paulista, once was a major lingua franca in Brazil, being replaced by Portuguese only after governmental prohibition led by major political changes), Baniwa and Tucano languages had been granted co-official status with Portuguese. There are significant communities of German (mostly the Brazilian Hunsrückisch, a High German language dialect) and Italian (mostly the Talian, a Venetian dialect) origins in the Southern and Southeastern regions, whose ancestors' native languages were carried along to Brazil, and which, still alive there, are influenced by the Portuguese language. Talian is officially a historic patrimony of Rio Grande do Sul, and two German dialects possess co-official status in a few municipalities. Italian is also recognized as ethnic language in the Santa Teresa microregion and Vila Velha (Espirito Santo state), and is taught as mandatory second language at school. Urbanization According to IBGE (Brazilian Institute of Geography and Statistics) urban areas already concentrate 84.35% of the population, while the Southeast region remains the most populated one, with over 80 million inhabitants. The largest urban agglomerations in Brazil are São Paulo, Rio de Janeiro, and Belo Horizonte – all in the Southeastern Region – with 21.1, 12.3, and 5.1 million inhabitants respectively. The majority of state capitals are the largest cities in their states, except for Vitória, the capital of Espírito Santo, and Florianópolis, the capital of Santa Catarina. Culture The core culture of Brazil is derived from Portuguese culture, because of its strong colonial ties with the Portuguese Empire. Among other influences, the Portuguese introduced the Portuguese language, Roman Catholicism and colonial architectural styles. The culture was also strongly influenced by African, indigenous and non-Portuguese European cultures and traditions. Some aspects of Brazilian culture were influenced by the contributions of Italian, German and other European as well as Japanese, Jewish and Arab immigrants who arrived in large numbers in the South and Southeast of Brazil during the 19th and 20th centuries. The indigenous Amerindians influenced Brazil's language and cuisine; and the Africans influenced language, cuisine, music, dance and religion. Brazilian art has developed since the 16th century into different styles that range from Baroque (the dominant style in Brazil until the early 19th century) to Romanticism, Modernism, Expressionism, Cubism, Surrealism and Abstractionism. Brazilian cinema dates back to the birth of the medium in the late 19th century and has gained a new level of international acclaim since the 1960s. Architecture The architecture of Brazil is influenced by Europe, especially Portugal. It has a history that goes back 500 years to the time when Pedro Álvares Cabral landed in Brazil in 1500. Portuguese colonial architecture was the first wave of architecture to go to Brazil. It is the basis for all Brazilian architecture of later centuries. In the 19th century during the time of the Empire of Brazil, the country followed European trends and adopted Neoclassical and Gothic Revival architecture. Then in the 20th century especially in Brasilia, Brazil experimented with Modernist architecture. The colonial architecture of Brazil dates to the early 16th century when Brazil was first explored, conquered and settled by the Portuguese. The Portuguese built architecture familiar to them in Europe in their aim to colonize Brazil. They built Portuguese colonial architecture which included churches, civic architecture including houses and forts in Brazilian cities and the countryside. During 19th century, Brazilian architecture saw the introduction of more European styles to Brazil such as Neoclassical and Gothic Revival architecture. This was usually mixed with Brazilian influences from their own heritage which produced a unique form of Brazilian architecture. In the 1950s, the modernist architecture was introduced when Brasilia was built as new federal capital in the interior of Brazil to help develop the interior. The architect Oscar Niemeyer idealized and built government buildings, churches and civic buildings in the modernist style. Music The music of Brazil was formed mainly from the fusion of European, Native Indigenous, and African elements. Until the nineteenth century, Portugal was the gateway to most of the influences that built Brazilian music, although many of these elements were not of Portuguese origin, but generally European. The first was José Maurício Nunes Garcia, author of sacred pieces with influence of Viennese classicism. The major contribution of the African element was the rhythmic diversity and some dances and instruments that had a bigger role in the development of popular music and folk, flourishing especially in the twentieth century. Popular music since the late eighteenth century began to show signs of forming a characteristically Brazilian sound, with samba considered the most typical and on the UNESCO cultural heritage list. Maracatu and Afoxê are two music traditions that have been popularized by their appearance in the annual Brazilian Carnivals. Capoeira is usually played with its own music referred to as capoeira music, which is usually considered to be a call-and-response type of folk music. Forró is a type of folk music prominent during the Festa Junina in northeastern Brazil. Jack A. Draper III, a professor of Portuguese at the University of Missouri, argues that Forró was used as a way to subdue feelings of nostalgia for a rural lifestyle. Choro is a very popular music instrumental style. Its origins are in 19th-century Rio de Janeiro. In spite of the name, the style often has a fast and happy rhythm, characterized by virtuosity, improvisation, subtle modulations and full of syncopation and counterpoint. Bossa nova is also a well-known style of Brazilian music developed and popularized in the 1950s and 1960s. The phrase "bossa nova" means literally "new trend". A lyrical fusion of samba and jazz, bossa nova acquired a large following starting in the 1960s. Literature Brazilian literature dates back to the 16th century, to the writings of the first Portuguese explorers in Brazil, such as Pêro Vaz de Caminha, filled with descriptions of fauna, flora and commentary about the indigenous population that fascinated European readers. Brazil produced significant works in Romanticism – novelists like Joaquim Manuel de Macedo and José de Alencar wrote novels about love and pain. Alencar, in his long career, also treated indigenous people as heroes in the Indigenist novels O Guaraní, Iracema and Ubirajara. Machado de Assis, one of his contemporaries, wrote in virtually all genres and continues to gain international prestige from critics worldwide. Brazilian Modernism, evidenced by the Modern Art Week in 1922, was concerned with a nationalist avant-garde literature, while Post-Modernism brought a generation of distinct poets like João Cabral de Melo Neto, Carlos Drummond de Andrade, Vinicius de Moraes, Cora Coralina, Graciliano Ramos, Cecília Meireles, and internationally known writers dealing with universal and regional subjects like Jorge Amado, João Guimarães Rosa, Clarice Lispector and Manuel Bandeira. Brazil's most significant literary award is the Camões Prize, which it shares with the rest of the Portuguese-speaking world. As of 2016, Brazil has eleven recipients of the prize. Brazil also holds its own literary academy, the Brazilian Academy of Letters, a non-profit cultural organization pointed in perpetuating the care of the national language and literature. Cuisine Brazilian cuisine varies greatly by region, reflecting the country's varying mix of indigenous and immigrant populations. This has created a national cuisine marked by the preservation of regional differences. Examples are Feijoada, considered the country's national dish; and regional foods such as beiju, feijão tropeiro, vatapá, moqueca, polenta (from Italian cuisine) and acarajé (from African cuisine). The national beverage is coffee and cachaça is Brazil's native liquor. Cachaça is distilled from sugar cane and is the main ingredient in the national cocktail, Caipirinha. A typical meal consists mostly of rice and beans with beef, salad, french fries and a fried egg. Often, it is mixed with cassava flour (farofa). Fried potatoes, fried cassava, fried banana, fried meat and fried cheese are very often eaten in lunch and served in most typical restaurants. Popular snacks are pastel (a fried pastry); coxinha (a variation of chicken croquete); pão de queijo (cheese bread and cassava flour / tapioca); pamonha (corn and milk paste); esfirra (a variation of Lebanese pastry); kibbeh (from Arabic cuisine); empanada (pastry) and empada, little salt pies filled with shrimps or heart of palm. Brazil has a variety of desserts such as brigadeiros (chocolate fudge balls), bolo de rolo (roll cake with goiabada), cocada (a coconut sweet), beijinhos (coconut truffles and clove) and Romeu e Julieta (cheese with goiabada). Peanuts are used to make paçoca, rapadura and pé-de-moleque. Local common fruits like açaí, cupuaçu, mango, papaya, cocoa, cashew, guava, orange, lime, passionfruit, pineapple, and hog plum are turned in juices and used to make chocolates, ice pops and ice cream. Cinema The Brazilian film industry began in the late 19th century, during the early days of the Belle Époque. While there were national film productions during the early 20th century, American films such as Rio the Magnificent were made in Rio de Janeiro to promote tourism in the city. The films Limite (1931) and Ganga Bruta (1933), the latter being produced by Adhemar Gonzaga through the prolific studio Cinédia, were poorly received at release and failed at the box office, but are acclaimed nowadays and placed among the finest Brazilian films of all time. The 1941 unfinished film It's All True was divided in four segments, two of which were filmed in Brazil and directed by Orson Welles; it was originally produced as part of the United States' Good Neighbor Policy during Getúlio Vargas' Estado Novo government. During the 1960s, the Cinema Novo movement rose to prominence with directors such as Glauber Rocha, Nelson Pereira dos Santos, Paulo Cesar Saraceni and Arnaldo Jabor. Rocha's films Deus e o Diabo na Terra do Sol (1964) and Terra em Transe (1967) are considered to be some of the greatest and most influential in Brazilian film history. During the 1990s, Brazil saw a surge of critical and commercial success with films such as O Quatrilho (Fábio Barreto, 1995), O Que É Isso, Companheiro? (Bruno Barreto, 1997) and Central do Brasil (Walter Salles, 1998), all of which were nominated for the Academy Award for Best Foreign Language Film, the latter receiving a Best Actress nomination for Fernanda Montenegro. The 2002 crime film City of God, directed by Fernando Meirelles, was critically acclaimed, scoring 90% on Rotten Tomatoes, being placed in Roger Ebert's Best Films of the Decade list and receiving four Academy Award nominations in 2004, including Best Director. Notable film festivals in Brazil include the São Paulo and Rio de Janeiro International Film Festivals and the Gramado Festival. Media The Brazilian press was officially born in Rio de Janeiro on 13 May 1808 with the creation of the Royal Printing National Press by the Prince Regent Dom João. The Gazeta do Rio de Janeiro, the first newspaper published in the country, began to circulate on 10 September 1808. The largest newspapers nowadays are , Super Notícia, O Globo and O Estado de S. Paulo. Radio broadcasting began on 7 September 1922, with a speech by then President Pessoa, and was formalized on 20 April 1923 with the creation of "Radio Society of Rio de Janeiro". Television in Brazil began officially on 18 September 1950, with the founding of TV Tupi by Assis Chateaubriand. Since then television has grown in the country, creating large commercial broadcast networks such as Globo, SBT, RecordTV, Bandeirantes and RedeTV. Today it is the most important factor in popular culture of Brazilian society, indicated by research showing that as much as 67% of the general population follow the same daily soap opera broadcast. By the mid-1960s Brazilian universities had installed mainframe computers from IBM, and Burroughs Large Systems. In the 1970s and 1980s the Brazilian government restricted foreign imports to protect the local manufacturing of computers. In the 1980s Brazil produced half of the computers sold in the country. By 2009 the mobile phone and Internet use of Brazil was the fifth largest in the world. In May 2010, the Brazilian government launched TV Brasil Internacional, an international television station, initially broadcasting to 49 countries. Commercial television channels broadcast internationally include Globo Internacional, RecordTV Internacional and Band Internacional. Visual arts Brazilian painting emerged in the late 16th century, influenced by Baroque, Rococo, Neoclassicism, Romanticism, Realism, Modernism, Expressionism, Surrealism, Cubism and Abstracionism making it a major art style called Brazilian academic art. The French Artistic Mission arrived in Brazil in 1816 proposing the creation of an art academy modeled after the respected Académie des Beaux-Arts, with graduation courses both for artists and craftsmen for activities such as modeling, decorating, carpentry and others and bringing artists like Jean-Baptiste Debret. Upon the creation of the Imperial Academy of Fine Arts, new artistic movements spread across the country during the 19th century and later the event called Modern Art Week definitely broke with academic tradition in 1922 and started a nationalist trend which was influenced by modernist arts. Among the best-known Brazilian painters are Ricardo do Pilar and Manuel da Costa Ataíde (baroque and rococo), Victor Meirelles, Pedro Américo and Almeida Júnior (romanticism and realism), Anita Malfatti, Ismael Nery, Lasar Segall, Emiliano di Cavalcanti, Vicente do Rego Monteiro, and Tarsila do Amaral (expressionism, surrealism and cubism), Aldo Bonadei, José Pancetti and Cândido Portinari (modernism). Sports The most popular sport in Brazil is football. The Brazilian men's national team is ranked among the best in the world according to the FIFA World Rankings, and has won the World Cup tournament a record five times. Volleyball, basketball, auto racing, and martial arts also attract large audiences. The Brazil men's national volleyball team, for example, currently holds the titles of the World League, World Grand Champions Cup, World Championship and the World Cup. In auto racing, three Brazilian drivers have won the Formula One world championship eight times. The country has also produced significant achievements in other sports such as sailing, swimming, tennis, surfing, skateboarding, MMA, gymnastics, boxing, judo, athletics and table tennis. Some sport variations have their origins in Brazil: beach football, futsal (indoor football) and footvolley emerged in Brazil as variations of football. In martial arts, Brazilians developed Capoeira, Vale tudo, and Brazilian jiu-jitsu. Brazil has hosted several high-profile international sporting events, like the 1950 FIFA World Cup and recently has hosted the 2014 FIFA World Cup, 2019 Copa América and 2021 Copa América . The São Paulo circuit, Autódromo José Carlos Pace, hosts the annual Grand Prix of Brazil. São Paulo organized the IV Pan American Games in 1963, and Rio de Janeiro hosted the XV Pan American Games in 2007. On 2 October 2009, Rio de Janeiro was selected to host the 2016 Olympic Games and 2016 Paralympic Games, making it the first South American city to host the games and second in Latin America, after Mexico City. Furthermore, the country hosted the FIBA Basketball World Cups in 1954 and 1963. At the 1963 event, the Brazil national basketball team won one of its two world championship titles.

Black Forest

The Black Forest ( ) is a large forested mountain range in the state of Baden-Württemberg in southwest Germany, bounded by the Rhine Valley to the west and south and close to the borders with France and Switzerland. It is the source of the Danube and Neckar rivers. Its highest peak is the Feldberg with an elevation of above sea level. Roughly oblong in shape, with a length of and breadth of up to , it has an area of about . Historically, the area was known for forestry and the mining of ore deposits, but tourism has now become the primary industry, accounting for around 300,000 jobs. There are several ruined military fortifications dating back to the 17th century. History In ancient times, the Black Forest was known as , after the Celtic deity, Abnoba. In Roman times (Late antiquity), it was given the name ("Marcynian Forest", from the Germanic word marka = "border"). The Black Forest probably represented the border area of the Marcomanni ("border people") who were settled east of the Roman . They, in turn, were part of the Germanic tribe of Suebi, who subsequently gave their name to the historic state of Swabia. With the exception of Roman settlements on the perimeter (e.g. the baths in Badenweiler, and mines near Badenweiler and Sulzburg) and the construction of the Roman road of Kinzigtalstraße, the colonization of the Black Forest was not carried out by the Romans but by the Alemanni. They settled and first colonized the valleys, crossing the old settlement boundary, the so-called "red sandstone border", for example, from the region of Baar. Soon afterwards, increasingly higher areas and adjacent forests were colonized, so that by the end of the 10th century, the first settlements could be found in the red (bunter) sandstone region. These include, for example, Rötenbach, which was first mentioned in 819. Some of the uprisings (including the Bundschuh movement) that preceded the 16th century German Peasants' War, originated in the Black Forest. Further peasant unrest, in the shape of the saltpetre uprisings, took place over the next two centuries in Hotzenwald. Remnants of military fortifications dating from the 17th and 18th centuries can be found in the Black Forest, especially on the mountain passes. Examples include the multiple baroque fieldworks of Margrave Louis William of Baden-Baden or individual defensive positions such as the Alexanderschanze (Alexander's Redoubt), the Röschenschanze and the Schwedenschanze (Swedish Redoubt). Originally, the Black Forest was a mixed forest of deciduous trees and firs. At the higher elevations spruce also grew. In the middle of the 19th century, the Black Forest was almost completely deforested by intensive forestry and was subsequently replanted, mostly with spruce monocultures. In 1990, extensive damage to the forest was caused by a series of windstorms. On 26 December 1999, Cyclone Lothar raged across the Black Forest and caused even greater damage, especially to the spruce monocultures. As had happened following the 1990 storms, large quantities of fallen logs were kept in provisional wet-storage areas for years. The effects of the storm are demonstrated by the Lothar Path, a forest educational and adventure trail at the nature centre in Ruhestein on a highland timber forest of about 10 hectares that was destroyed by a hurricane. Several areas of storm damage, both large and small, were left to nature and have developed today into a natural mixed forest again. Geography The Black Forest stretches from the High Rhine in the south to the Kraichgau in the north. In the west it is bounded by the Upper Rhine Plain (which, from a natural region perspective, also includes the low chain of foothills); in the east it transitions to the Gäu, Baar and hill country west of the Klettgau. From north to south, the Black Forest extends for over , attaining a width of up to in the south and in the north. The Black Forest is the highest part of the South German Scarplands, and much of it is densely wooded, a fragment of the Hercynian Forest of antiquity. Administratively, the Black Forest belongs completely to the state of Baden-Württemberg and comprises the cities of Freiburg, Pforzheim and Baden-Baden as well as the following districts (Kreise). In the north: Enz, Rastatt and Calw; in the middle: Freudenstadt, Ortenaukreis and Rottweil; in the south: Emmendingen, Schwarzwald-Baar, Breisgau-Hochschwarzwald, Lörrach and Waldshut. Natural regions The natural regions of the Black Forest are separated by various features. Geomorphologically, the main division is between the gentle eastern slopes with their mostly rounded hills and broad plateaux (so-called Danubian relief, especially prominent in the north and east on the Bunter Sandstone) and the deeply incised, steeply falling terrain in the west that drops into the Upper Rhine Graben; the so-called Valley Black Forest () with its Rhenanian relief. It is here, in the west, where the highest mountains and the greatest local differences in height (of up to 1000 metres) are found. The valleys are often narrow and ravine-like. The summits are rounded, and there are remnants of plateaux and -like landforms. Geologically the clearest division is also between east and west. Large areas of the eastern Black Forest, the lowest layer of the South German Scarplands composed of Bunter Sandstone, are covered by seemingly endless coniferous forest with their island clearings. The exposed basement in the west, predominantly made up of metamorphic rocks and granites, was, despite its rugged topography, easier to settle and appears much more open and inviting today with its varied meadow valleys. The most common way of dividing the regions of the Black Forest is, however, from north to south. Until the 1930s, the Black Forest was divided into the Northern and Southern Black Forest, the boundary being the line of the Kinzig valley. Later the Black Forest was divided into the heavily forested Northern Black Forest, the lower, central section, predominantly used for agriculture in the valleys, was the Central Black Forest and the much higher Southern Black Forest with its distinctive highland economy and ice age glacial relief. The term High Black Forest referred to the highest areas of the South and southern Central Black Forest. The boundaries drawn were, however, quite varied. In 1931, Robert Gradmann called the Central Black Forest the catchment area of the Kinzig and in the west the section up to the lower Elz and Kinzig tributary of the Gutach. A pragmatic division, which is oriented not just on natural and cultural regions, uses the most important transverse valleys. Based on that, the Central Black Forest is bounded by the Kinzig in the north and the line from Dreisam to Gutach in the south, corresponding to the Bonndorf Graben zone and the course of the present day B 31. In 1959, Rudolf Metz combined the earlier divisions and proposed a modified tripartite division, which combined natural and cultural regional approaches and was widely used. His Central Black Forest is bounded in the north by the watershed between the Acher and Rench and subsequently between the Murg and Kinzig or Forbach and Kinzig, in the south by the Bonndorf Graben zone, which restricts the Black Forest in the east as does the Freudenstadt Graben further north by its transition into the Northern Black Forest. Work of the Institute of Applied Geography The Handbook of the Natural Region Divisions of Germany published by the Federal Office of Regional Geography () since the early 1950s names the Black Forest as one of six tertiary-level major landscape regions within the secondary-level region of the South German Scarplands and, at the same time, one of nine new major landscape unit groups. It is divided into six so-called major units (level 4 landscapes). This division was refined and modified in several successor publications (1:200,000 individual map sheets) up to 1967, each covering individual sections of the map. The mountain range was also divided into three regions. The northern boundary of the Central Black Forest in this classification runs south of the Rench Valley and the Kniebis to near Freudenstadt. Its southern boundary varied with each edition. In 1998, the Baden-Württemberg State Department for Environmental Protection (today the Baden-Württemberg State Department for the Environment, Survey and Nature Conservation) published a reworked Natural Region Division of Baden-Württemberg. It is restricted to the level of the natural regional major units and has been used since for the state's administration of nature conservation: The Black Forest Foothills (, 150) geomorphologically form plateaux on the north and northeast periphery of the mountain range that descend to the Kraichgau in the north and the Heckengäu landscapes in the east. They are incised by valleys, especially those of the Nagold river system, into individual interfluves; a narrow northwestern finger extends to beyond the Enz near Neuenbürg and also borders the middle reaches of the Alb to the west as far as a point immediately above Ettlingen. To the southwest it is adjoined by the Black Forest Grinden and Enz Hills (, 151), along the upper reaches of the Enz and Murg, forming the heart of the Northern Black Forest. The west of the Northern Black Forest is formed by the Northern Black Forest Valleys (, 152) with the middle reaches of the Murg around Gernsbach, the middle course of the Oos to Baden-Baden, the middle reaches of the Bühlot above Bühls and the upper reaches of the Rench around Oppenau. Their exit valleys from the mountain range are all oriented towards the northwest. The Central Black Forest (153) is mainly restricted to the catchment area of the River Kinzig above Offenburg as well as the Schutter and the low hills north of the Elz. The Southeastern Black Forest (, 154) consists mainly of the catchment areas of the upper reaches of the Danube headstreams, the Brigach and Breg as well as the left side valleys of the Wutach north of Neustadt – and thus draining from the northeast of the Southern Black Forest. To the south and west it is adjoined by the High Black Forest (, 155) with the highest summits in the whole range around the Feldberg and the Belchen. Its eastern part, the Southern Black Forest Plateau, is oriented towards the Danube, but drained over the Wutach and the Alb into the Rhine. The southern crest of the Black Forest in the west is deeply incised by the Rhine into numerous ridges. Immediately right of the Wiese above Lörrach rises the relatively small Bunter Sandstone-Rotliegendes table of the Weintenau Uplands () in the extreme southwest of the Black Forest; morphologically, geologically and climatically it is separate from the other parts of the Southern Black Forest and, in this classification, is also counted as part of the High Black Forest. Mountains At the Feldberg in the Southern Black Forest is the range's highest summit. Also in the same area are the Herzogenhorn (1,415 m) and the Belchen (1,414 m). In general the mountains of the Southern or High Black Forest are higher than those in the Northern Black Forest. The highest Black Forest peak north of the Freiburg–Höllental–Neustadt line is the Kandel (1,241.4 m). Like the highest point of the Northern Black Forest, the Hornisgrinde (1,163 m), or the Southern Black Forest lookout mountains, the Schauinsland (1,284.4 m) and Blauen (1,164.7 m) it lies near the western rim of the range. Rivers and lakes Rivers in the Black Forest include the Danube (which originates in the Black Forest as the confluence of the Brigach and Breg rivers), the Enz, the Kinzig, the Murg, the Nagold, the Neckar, the Rench, and the Wiese. The Black Forest occupies part of the continental divide between the Atlantic Ocean drainage basin (drained by the Rhine) and the Black Sea drainage basin (drained by the Danube). The longest Black Forest rivers are (length includes stretches outside the Black Forest): Enz () Kinzig () Elz () Wutach () Nagold (), hydrological main artery of the Nagold-Enz systems Danube (), headstreams: Breg () Brigach () Murg () Rench () Schutter () Wiese () Acher () Dreisam (incl. Rotbach ) Alb (incl. Menzenschwander Alb ) Glatt () Möhlin () Wolf () Schiltach () Wehra (incl. Rüttebach ) Oos () Glasbach (), hydrological main artery of the Neckar system Important lakes of natural, glacial origin in the Black Forest include the Titisee, the Mummelsee and the Feldsee. Especially in the Northern Black Forest are a number of other, smaller tarns. Numerous reservoirs like the – formerly natural but much smaller – Schluchsee with the other lakes of the Schluchseewerk, the Schwarzenbach Reservoir, the Kleine Kinzig Reservoir or the Nagold Reservoir are used for electricity generation, flood protection or drinking water supply. Geology The Black Forest consists of a cover of sandstone on top of a core of gneiss and granite. Formerly it shared tectonic evolution with the nearby Vosges Mountains. Later during the Middle Eocene a rifting period affected the area and caused formation of the Upper Rhine Plain. During the last glacial period of the Würm glaciation, the Black Forest was covered by glaciers; several tarns (or lakes) such as the Mummelsee are remains of this period. Basement The geological foundation of the Black Forest is formed by the crystalline bedrock of the Variscan basement. This is covered in the east and northeast by Bunter Sandstone slabs, the so-called platforms. On the western edge a descending, step-fault-like, foothill zone borders the Upper Rhine Graben consisting of rocks of the Triassic and Jurassic periods. The dominant rocks of the basement are gneiss (ortho- and paragneisses, in the south also migmatites and diatexites, for example on the Schauinsland and Kandel). These gneisses were penetrated by a number of granitic bodies during the Carboniferous period. Among the bigger ones are the Triberg Granite and the Forbach Granite, the youngest is the Bärhalde Granite. In the south lies the zone of Badenweiler-Lenzkirch, in which Palaeozoic rocks have been preserved (volcanite and sedimentary rocks), which are interpreted as the intercalated remains of a microcontinental collision. Still further in the southeast (around Todtmoos) is a range of exotic inclusions: gabbro from Ehrsberg, serpentinites and pyroxenites near Todtmoos, norite near Horbach), which are possibly the remnants of an accretionary wedge from a continental collision. Also noteworthy are the basins in the Rotliegend, for example the Schramberg or the Baden-Baden Basin with thick quartz-porphyry and tuff plates (exposed, for example, on the rock massif of Battert near Baden-Baden). Thick rock, covered by bunter, also occurs in the north of the Dinkelberg block (several hundred metres thick in the Basel geothermal borehole). Even further to the southeast, under the Jura, lies the North Swiss Permocarboniferous Basin. Uplift of the mountains Since the downfaulting of the Upper Rhine Graben during the Eocene epoch, the two shoulders on either side have been uplifted: the Black Forest to the east and the Vosges to the west. In the centre lies the Kaiserstuhl volcano, which dates to the Miocene. In the times that followed, the Mesozoic platform on the uplands was largely eroded, apart from remains of Bunter Sandstone and Rotliegend Group, but it has survived within the graben itself. During the Pliocene a pronounced but uneven bulge especially affected the southern Black Forest, including the Feldberg. As a result, the upper surface of the basement in the northern part of the forest around the Hornisgrinde is considerably lower. In the central Black Forest, the tectonic syncline of the Kinzig and Murg emerged. Geomorphologist Walther Penck regarded the Black Forest as an uplifted geologic dome and modeled his theory of piedmonttreppen (piedmont benchlands) on it. Platform Above the crystalline basement of the Northern Black Forest and the adjacent parts of the Central Black Forest, the bunter sandstone platforms rise in prominent steps. The most resistant surface strata on the stepped terrain of the uplands and the heights around the upper reaches of the Enz, which have been heavily eroded by the tributaries of the Murg, is the silicified main conglomerate (Middle Bunter). To the east and north are the nappes of the Upper Bunter (platten sandstones and red clays). South of the Kinzig the Bunter Sandstone zone narrows to a fringe in the east of the mountain range. Ice age and topography It is considered proven that the Black Forest was heavily glaciated during the peak periods of at least the Riss and Würm glaciations (up to about 10,000 years ago). This glacial geomorphology characterizes almost all of the High Black Forest as well as the main ridge of the Northern Black Forest. Apart from that, it is only discernible from a large number of cirques mainly facing northeast. Especially in this direction snow accumulated on the shaded and leeward slopes of the summit plateau to form short cirque glaciers that made the sides of these funnel-shaped depressions. There are still tarns in some of these old cirques, partly a result of the anthropogenic elevation of the low-side lip of the cirque, such as the Mummelsee, Wildsee, Schurmsee, Glaswaldsee, Buhlbachsee, Nonnenmattweiher, and Feldsee. The Titisee formed as glacial lake behind a glacial moraine. Culture The Black Forest is mainly rural, with many scattered villages and a few large towns. Tradition and custom are celebrated in many places in the form of annual festivities. The main dialect spoken in the Black Forest area is Alemannic. The forest is best known for its typical farmhouses with their sweeping half-hipped roofs, its Black Forest gâteaus, Black Forest ham, Black Forest gnomes, Kirschwasser and the cuckoo clock. Traditional costume Traditional costume or Tracht is still sometimes worn today, usually at festive occasions. The appearance of such costume varies from region to region, sometimes markedly. One of the best-known Black Forest costumes is that of the villages of Kirnbach, Reichenbach and Gutach im Kinzigtal with the characteristic Bollenhut headdress. Unmarried women wear the hats with red bobbles or Bollen; married women wear black. Engaged women sometimes wear a bridal crown (Schäppel) before and on the day of their wedding, whose largest examples from the town of St. Georgen weigh up to 5 kilograms. Art Its rural beauty as well as the sense of tradition of its inhabitants attracted many artists in the 19th and early 20th centuries, whose works made the Black Forest famous the world over. Notable were Hans Thoma from Bernau and his fellow student, Rudolf Epp, who was sponsored by the Grand Duke of Baden, Frederick I. Both artists painted motifs from the Black Forest throughout their lives. Artist J. Metzler from Düsseldorf travelled through the Black Forest to paint his landscapes. The works of the Gutach artist colony around Wilhelm Hasemann were widely admired, their landscape and genre motifs capturing the character of the Black Forest. Like local author Heinrich Hansjakob, they were part of a Baden folk costume movement. Crafts In the field of handicrafts, wood carving produces folk art like the Longinus crosses along with sculptors like Matthias Faller. Wood carving is a traditional cottage industry in the region, and carved ornaments now are produced in substantial numbers as souvenirs for tourists. Cuckoo clocks are a popular example. Glassblowing is another notable craft of the Black Forest region. At the beginning of the 15th century, the art of glassmaking took hold in the Bavarian-Bohemian border mountains, especially since the necessary raw materials such as quartz and wood were abundant here. With the permission of the manor, glassblowers operated simple glass production facilities as "wandering huts" (Wanderhütten), the locations of which were relocated when the local resources were available. They needed huge amounts of firewood and wood for potash. In the second half of the 18th century, the huts had to close due to a shortage of wood and sales difficulties. Only after 1800, when the demand for luxury glass increased enormously, when a few decades of regulated forestry had ensured the regrowth of the raw material wood and when the forest-destroying potash extraction had become unnecessary due to the new glass flux soda, some glass huts (Glashütten) revived. Some glassblowing factories still testify to this today, for example in Höllental, near Todtnau and in Wolfach. Cuisine Black Forest ham originated from this region, as did the Black Forest gâteau, which is also known as "Black Forest Cherry Cake" or "Black Forest Cake" and is made with chocolate cake, cream, sour cherries and Kirsch. The Black Forest variety of Flammekueche is a Baden specialty made with ham, cheese and cream. Pfannkuchen, a crêpe or crêpe-like (Eierkuchen or Palatschinken) pastry, is also common. The Black Forest is known for its long tradition in gourmet cuisine. No fewer than 17 Michelin starred restaurants are located in the region, among them two restaurants with three stars (Restaurants Bareiss and Schwarzwaldstube in Baiersbronn) as well as the only restaurant in Germany that has been awarded a Michelin star every year since 1966. At Schwarzwald Hotel Adler in Häusern, three generations of chefs from the same family have defended the award from the first year the Michelin Guide selected restaurants in Germany until today. Fasnet The German holiday of Fastnacht, or Fasnet, as it is known in the Black Forest region, occurs in the time leading up to Lent. On Fasnetmendig, or the Monday before Ash Wednesday, crowds of people line the streets, wearing wooden, mostly hand-carved masks. One prominent style of mask is called the Black Forest Style, originating from the Black Forest Region. Cego The Black Forest is home to an unusual tarot card game called Cego, that is part of the region's cultural heritage. After the defeat of Further Austria in 1805, much of its territory was allocated to the Grand Duchy of Baden. During the ensuing Napoleonic Wars, soldiers from Baden deployed with Napoleon's troops to Spain where, among other things, they learned a new card game, Ombre. They took this back to Baden and adapted it to be played with Tarot cards which were then in common use in southern Germany. Cego soon developed into the national game of Baden and Hohenzollern, and these are the only regions of Germany where tarot cards are still used for playing games. The game has grown organically, and there are many regional variations, but in recent years the establishment of a Cego Black Forest Championship has led to official tournament rules being defined. In addition, regular courses and local tournaments are held and it is a permanent feature of Alemannic Week, held annually in the Black Forest at the end of September. Nature Conservation areas There are two nature parks and one national park named after the Black Forest that cover the region: the Southern Black Forest Nature Park, the Central/North Black Forest and the Black Forest National Park. The difference between a nature park and a national park is that a nature park's aim is to strive for environmentally sustainable land use, to preserve the countryside as a cultural landscape, to market local produce more effectively, to make the area more suitable for sustainable tourism and to practice environmental education. A national park's aims are to protect the country's natural heritage, to practice environmental education, to serve purposes of scientific environmental observation and to prevent the area from being commercially exploited. The Southern Black Forest Nature Park (Naturpark Südschwarzwald) was founded in 1999. It comprises 394,000 ha and is therefore Germany's largest nature park (as of 2020). It encloses the southern part of the Central Black Forest, the Southern Black Forest and adjacent areas. The Central/North Black Forest Nature Park (Naturpark Schwarzwald Mitte/Nord) was founded in 2000. It covers 375,000 ha and is thus the second-largest in Germany (as of 2020). It begins in the southern part of the Central Black Forest, bordering on the Southern Black Forest Nature Park and covers the rest of the Black Forest to the north. The Black Forest National Park, established in 2014, is the first national park in Baden-Württemberg. It lies completely within the Central/North Black Forest Nature Park between the cities of Freudenstadt and Baden-Baden and covers an area of 10,062 ha. Its motto is "Natur Natur sein lassen" (let nature be nature). Fauna In addition to the characteristic range of fauna found in Central European forests, the following less common animals may be observed in the Black Forest: Black Forest cattle which belong to the rare breed of Hinterwälder cattle, the giant earthworm Lumbricus badensis, which is found only in the Black Forest region, the Black Forest Horse, a draft horse once indispensable for heavy field work and nowadays an endangered breed, and the endangered Western capercaillie. Climate The mountain range has lower temperatures and higher rainfall than its surrounding countryside. The highlands of the Black Forest are characterized by regular rainfall throughout the year. However, temperatures do not fall evenly with increasing elevation, nor does the rainfall increase uniformly. Rather, the precipitation rises quickly even in the lower regions and is disproportionately heavy on the rainier western side of the mountains. The wettest areas are the highlands around the Hornisgrinde in the north and around the Belchen and Feldberg in the south, where annual rainfall reaches 1,800–2,100 mm. Moisture-laden Atlantic westerlies dump about as much rain in the Northern Black Forest, despite its lower elevation, than in the higher area of the Southern Black Forest. There, the Vosges act as a rain shield in the face of the prevailing winds. On the exposed east side of the Central Black Forest, it is much drier; the annual rainfall there is about 750 L/m2. The higher elevations of the Black Forest are characterized by relatively small annual fluctuations and steamed extreme values. This is the result of the frequent light winds and greater cloud cover in summer. During the winter months, frequent high pressure means that the summits are often bathed in sunshine, while the valleys disappear under a thick blanket of fog as a result of pockets of cold air (temperature inversion). Tourism and transport The main industry of the Black Forest is tourism. Black Forest Tourism (Schwarzwald Tourismus) assesses that there are around 140,000 direct full-time jobs in the tourist sector and around 34.8 million tourist overnight stays in 2009. In spring, summer and autumn an extensive network of hiking trails and mountain bike routes enable different groups of people to use the natural region. In winter, it is the various types of winter sport that come to the fore. There are facilities for both downhill and Nordic skiing in many places. Tourist attractions The most heavily frequented tourist destinations and resorts in the Black Forest are the Titisee and the Schluchsee. Both lakes offer opportunities for water sports like diving and windsurfing. The Mummelsee is a recreational lake and a starting point for a number of hiking trails including the Kunstpfad am Mummelsee ("sculpture trail at the Mummelsee"). The Murg valley, the Kinzig valley, the Triberg Waterfalls and the Open Air Museum at Vogtsbauernhof are also popular. Lookout mountains include the Feldberg, the Belchen, the Kandel and the Schauinsland in the Southern Black Forest; and the Hornisgrinde, the Schliffkopf, the Hohloh, the Merkur and the Teufelsmühle in the Northern Black Forest. The height differences in the mountains are used in many places for hang gliding and paragliding. One oft-visited town is Baden-Baden with its thermal baths and festival hall. Other thermal baths are found in the spa resorts of Badenweiler, Bad Herrenalb, Bad Wildbad, Bad Krozingen, Bad Liebenzell and Bad Bellingen. From the beginning of the 19th century, the desire for spa and bathing resorts arose in all of Central Europe because of the increasing economic potential, increasing mobility and the use of advertising. The Neo-renaissance style Friedrichsbad and the Palais Thermal are examples for spas built in this era. Other tourist destinations are the old imperial town of Gengenbach, the former county towns of Wolfach, Schiltach and Haslach im Kinzigtal and the flower and wine village of Sasbachwalden at the foot of the Hornisgrinde. Picturesque old towns may be visited in Altensteig, Dornstetten, Freiburg im Breisgau, Gernsbach, Villingen and Zell am Harmersbach. Baiersbronn is a centre of gastronomic excellence, Freudenstadt is built around the largest market place in Germany. Gersbach's floral displays have won awards as the German Golden Village of 2004 and the European Golden Village of 2007. Noted for their fine interiors are the former monastery of St. Blasien as well as the abbeys of Sankt Trudpert, St. Peter and St. Märgen. Alpirsbach Abbey and the ruined Hirsau Abbey were built of red sandstone in the Hirsau style. Another idyllic rural edifice is Wittichen Abbey near Schenkenzell. There are well known winter sports areas around the Feldberg, near Todtnau with its FIS downhill ski run of Fahler Loch and in Hinterzarten, a centre and talent forge for German ski jumpers. In the Northern Black Forest, the winter-sports areas are concentrated along the Black Forest High Road and on the ridge between the Murg and Enz rivers around Kaltenbronn. Hiking trails The Black Forest has a great number of very varied trails; some of pan-regional significance. The European long-distance path E1 crosses the Black Forest following the routes of some of the local long-distance paths. Their framework is a network of long-distance paths with main routes and side branches, many of which were laid out in the early 20th century by the Black Forest Club (Schwarzwaldverein). The best known of these is the challenging West Way (Westweg) with its many steep inclines. After 1950, circular walks were constructed to meet the changing demand, initially from the relatively dense railway network and, later, mainly from locally established hiking car parks. Currently, special, more experience-oriented themed paths are being laid out, such as the Dornstetten Barefoot Park (Barfußpark Dornstetten), the Park of All Senses (Park mit allen Sinnen) in Gutach (Black Forest Railway), as well as those designed to bring the walker more directly in contact with nature (e.g. the Schluchtensteig). Roads and wide forest tracks are thus less often used than hitherto. There are numerous shorter paths suitable for day walks, as well as mountain biking and cross-country skiing trails. The total network of tracks amounts to around , and is maintained and overseen by volunteers of the Black Forest Club (figures from Bremke, 1999, p. 9), which is the second largest German hiking association. As of 2021, the club counts 65,000 members. Museums in the Black Forest Culture and crafts The Black Forest Open Air Museum at the Vogtsbauernhof farm in Gutach has original Black Forest houses offering insights into farming life of the 16th and 17th centuries. The buildings were dismantled at their original sites, the individual pieces numbered and then re-erected to exactly the same plan in the museum. The open-air museum shows the life of 16th and 17th century farmers in the region featuring the Vogtsbauernhof which dates back to 1612. The German Clock Museum in Furtwangen gives a comprehensive cross-section of the history of the watchmaking and clockmaking industries. From this early precision engineering a formerly important phonographic industry developed in the 20th century; the history of leisure electronics is presented in the German Phono Museum in St. Georgen. The Schüttesäge Museum in Schiltach has information and living history demonstrations covering the themes of lumbering and timber rafting in the Kinzig valley as well as tanning. The Black Forest Costume Museum in Haslach im Kinzigtal offers an overview of the traditional costume of the whole of the Black Forest and its peripheral regions. Also located in Haslach: the Hansjakob Museum and the Hansjakob Archive with numerous works of the writer, priest, politician, historian and chronicler, Heinrich Hansjakob. Nature and science The MiMa Mineralogy and Mathematics Museum in Oberwolfach houses minerals and mining exhibits from the whole of the Black Forest and links them to mathematical explanations. Infrastructure Road transport Several tourist routes run through the Black Forest. Well known holiday routes are the Black Forest High Road (B 500) and the German Clock Road. Thanks to its winding country roads, the Black Forest is a popular destination for motorcyclists. This arm of tourism is controversial due to the high number of accidents and the wide-ranging noise pollution and has been restricted through the introduction of speed limits and by placing certain roads out of bounds. For example, since 1984, motorcyclists have been banned from using the mountain-racing route on the Schauinsland during summer weekends. Railway transport The whole of the Black Forest was once linked by railway. In the eastern part of the Northern Black Forest by the Enz Valley Railway from Pforzheim to Bad Wildbad, by the Nagold Valley Railway from Pforzheim via Calw and Nagold to Horb am Neckar, by the Württemberg Black Forest Railway from Stuttgart to Calw and the Gäu Railway from Stuttgart to Freudenstadt or its present-day section from Eutingen to Freudenstadt. Many railway lines run from the Rhine Plain up the valleys into the Black Forest: the Alb Valley Railway runs from Karlsruhe to Bad Herrenalb, the Murg Valley Railway from Rastatt to Freudenstadt, the Acher Valley Railway from Achern to Ottenhöfen im Schwarzwald and the Rench Valley Railway from Appenweier to Bad Griesbach. The Baden Black Forest Railway has linked Offenburg with Konstanz on Lake Constance since 1873, running via Hausach, Triberg, St. Georgen, Villingen and Donaueschingen. In Hausach the Kinzig Valley Railway branches off to Freudenstadt, in Denzlingen the Elz Valley Railway peels off towards Elzach, the Höllental Railway runs from Freiburg im Breisgau through the Höllental valley to Donaueschingen, the Münstertal Railway from Bad Krozingen to Münstertal, the Kander Valley Railway from Haltingen near Basel through the Kander valley to Kandern and the Wiesen Valley Railway from Basel to Zell im Wiesental. The Three Lakes Railway branches off at the Titisee from the Höllental Railway and runs to the Windgfällweiher and the Schluchsee. The Wutach Valley Railway runs along the border between Baden-Württemberg and Switzerland, linking Waldshut-Tiengen with Immendingen on the Black Forest Railway. Most of these routes are still busy today, whilst some are popular heritage lines. Administration Since January 2006, the Black Forest Tourist organisation, Schwarzwald Tourismus, whose head office is in Freiburg, has been responsible for the administration of tourism in the 320 municipalities of the region. Hitherto there had been four separate tourist associations. Points of interest There are many historic towns in the Black Forest. Popular tourist destinations include Baden-Baden, Freiburg, Calw (the birth town of Hermann Hesse), Gengenbach, Staufen, Schiltach, Haslach and Altensteig. Other popular destinations include such mountains as the Feldberg, the Belchen, the Kandel, and the Schauinsland; the Titisee and Schluchsee lakes; the All Saints Waterfalls; the Triberg Waterfalls, not the highest, but the most famous waterfalls in Germany; and the gorge of the River Wutach. For drivers, the main route through the region is the fast A 5 (E35) motorway, but a variety of signposted scenic routes such as the Schwarzwaldhochstraße (, Baden-Baden to Freudenstadt), Schwarzwald Tälerstraße (, the Murg and Kinzig valleys) or Badische Weinstraße (Baden Wine Street, , a wine route from Baden-Baden to Weil am Rhein) offers calmer driving along high roads. The last is a picturesque trip starting in the south of the Black Forest going north and includes numerous old wineries and tiny villages. Another, more specialized route is the German Clock Route, a circular route that traces the horological history of the region. Due to the rich mining history dating from medieval times (the Black Forest was one of the most important mining regions of Europe ) there are many mines re-opened to the public. Such mines may be visited in the Kinzig valley, the Suggental, the Muenster valley, and around Todtmoos. The Black Forest was visited on several occasions by Count Otto von Bismarck during his years as Prussian and later German chancellor (1862–1890). Allegedly, he was especially interested in the Triberg Waterfalls. There is now a monument in Triberg dedicated to Bismarck, who apparently enjoyed the tranquility of the region as an escape from his day-to-day political duties in Berlin. The Black Forest featured in the philosophical development of Martin Heidegger. Heidegger wrote and edited some of his philosophical works in a small hut in the Black Forest, and would receive visitors there for walks, including his former pupil Hannah Arendt. This hut features explicitly in his essay Building, Dwelling, Thinking. His walks in the Black Forest are supposed to have inspired the title of his collection of essays Holzwege, translated as Off The Beaten Track. Economy and craftsmanship Mining Mining developed in the Black Forest due to its ore deposits, which were often lode-shaped. The formation of these deposits (Schauinsland Pit: zinc, lead, about 700–1000 g silver/ton of lead; baryte, fluorite, less lead and zinc in the Kinzig valley; BiCoNi ores near Wittichen, uranium discovered in the Krunkelbach valley near Menzenschwand but never officially mined) often used to be linked to the intrusion of Carboniferous granite in the para- and orthogneisses. More recent research has revealed that most of these lode fillings are much younger (Triassic to Tertiary). Economic deposits of other minerals included: fluorite in the Northern Black Forest near Pforzheim, baryte in the central region near Freudenstadt, fluorite along with lead and silver near Wildschapbach, baryte and fluorite in the Rankach valley and near Ohlsbach, in the Southern Black Forest near Todtnau, Wieden and Urberg. Small liquid magmatic deposits of nickel-magnetite gravel in norite were mined or prospected in the Hotzenwald forest near Horbach and Todtmoos. Strata-bound deposits include iron ores in the Dogger layer of the foothill zone and uranium near Müllenbach/Baden-Baden. Stone coal is only found near Berghaupten and Diersburg, but was always only of local importance. Chronology: Stone Age mining of haematite (as red pigment) near Sulzburg. By the 5th and 6th centuries B.C. iron ore was being mined by the Celts in the Northern Black Forest (for example in Neuenbürg). Especially in the Middle Black Forest, but also in the south (for example in the Münster valley) ore mining was already probably taking place in Roman times (mining of silver and lead ore; evidence of this at Sulzburg and possibly Badenweiler). Until the High Middle Ages the High Black Forest was practically unsettled. In the course of inland colonisation in the Late High Middle Ages even the highlands were cultivated by settlers from the abbeys (St. Peter's, St. Märgen's). In the Late High Middle Ages (from about 1100) mining experienced another boom, especially around Todtnau, in the Münster and Suggen valleys and, later, on the Schauinsland too. It is believed that around 800–1,000 miners lived and worked in the Münster valley until the end of the Middle Ages. After the Plague, which afflicted the valley in 1516, the German Peasants' War (1524–26) and the Thirty Years' War, mining in the region declined until just a few pits remained. An important mining area was the Kinzig valley and its side valleys. The small mining settlement of Wittichen near Schenkenzell in the upper Kinzig valley had many pits from which miners dug baryte, cobalt and silver of many kinds. A circular, geological footpath runs today past the old pits and tips. Another boom began in the early 18th century after the loss of the Alsace to France. It lasted until the 19th century. Many pits from this period may be visited today as show mines; for example the Teufelsgrund Pit (Münstertal), the Finstergrund Pit near Wieden, the Hoffnungsstollen ("Hope Gallery") at Todtmoos, the mine in the Schauinsland, the formerly especially silver-rich Wenzel Pit in Oberwolfach and Gr. Segen Gottes ("God's Great Blessing") in Haslach-Schnellingen. Non-ferrous metal mining in the Black Forest continued until the middle of the 20th century near Wildschapbach and on the Schauinsland (to 1954); fluorite and baryte are still mined today at the Clara Pit in the Rankach valley in Oberwolfach. Iron ores of the Dogger formation was worked until the 1970s near Ringsheim and was smelted in Kehl. Compared with the Harz and Ore Mountains the quantities of silver extracted in the Black Forest were rather modest and reached only about ten percent of that produced in the other silver-mining regions. There are many show mines in the Black Forest. These include: the Frischglück Pit near Neuenbürg, the Hella Glück Pit near Neubulach, the Silbergründle Pit near Seebach, the Himmlich Heer Pit near Hallwangen, the Heilige Drei Könige Pit near Freudenstadt, the Segen Gottes Pit near Haslach, the Wenzel Pit near Oberwolfach, the Caroline Pit near Sexau, the Suggental Silver Mine near Waldkirch, the Schauinsland Pit near Freiburg, the Teufelsgrund Pit near Münstertal, the Finstergrund Pit near Wieden and the Hoffnungsstollen Pit near Todtmoos. Forestry For several centuries logs from the Black Forest were rafted down the Enz, Kinzig, Murg, Nagold and Rhine rivers for use in the shipping industry, as construction timber and for other purposes. This branch of industry boomed in the 18th century and led to large-scale clearances. As most of the long, straight pine logs were transported downriver for shipbuilding in the Netherlands, they were referred to as "Dutchmen". The logs were used in the Netherlands, above all, as piles for house construction in the sandy and wet ground. Even today in Amsterdam large numbers of historic building are built on these posts and the reforestation of the Black Forest with spruce monocultures testifies to the destruction of the original mixed forest. With the expansion of the railway and road network as alternative transportation, rafting largely came to an end in the late 19th century. Today, loggers harvest fir trees—especially very tall and branchless ones—mainly to ship to Japan. The global advertising impact of Expo 2000 fuelled a resurgence of timber exports. The importance of the timber resources of the Black Forest has also increased sharply recently due to the increasing demand for wood pellets for heating. Glass-making, charcoal-burning and potash-mining The timber resources of the Black Forest provided the basis for other sectors of the economy that have now largely disappeared. Charcoal burners (Köhler) built their wood piles (Meiler) in the woods and produced charcoal, which, like the products of the potash boilers—further processed inter alia for the glassmaking industry. The Black Forest supplied raw materials and energy for the manufacture of forest glass. This is evidenced today by a number of glassblowing houses e.g. in the Hoellental in Todtnau and Wolfach and the Forest Glass Centre in Gersbach (Schopfheim), which is open to visitors. Precision-engineering, clock and jewellery manufacture In the relatively inaccessible Black Forest valleys industrialization did not arrive until late in the day. In winter, many farmers made wooden cuckoo clocks to supplement their income. This developed in the 19th century into the precision engineering and watch industry, which boomed with the arrival of the railway in many of the Black Forest valleys. The initial disadvantage of their remote location, which led to the development of precision-engineered wooden handicrafts, became a competitive advantage because of their access to raw materials: timber from the forest and metal from the mines. As part of a structural support programme the Baden State Government founded the first clockmaking school in 1850 in Furtwangen to ensure that small artisans were given good training and thus better sales opportunities. Due to the increasing demand for mechanical devices, large companies such as Junghans and Kienzle became established. In the 20th century, the production of consumer electronics was developed by companies such as SABA, Dual and Becker. In the 1970s, the industry declined due to Far Eastern competition. Nevertheless, the Black Forest remains a centre for the metalworking industry and is home to many high-tech companies. Since the start of industrialisation there have been numerous firms in Pforzheim that manufacture jewellery and work with precious metals and stones. There is also a goldsmith's school in Pforzheim. Hydropower Due to the large amounts of precipitation and elevation changes the Black Forest has significant hydropower potential. This was used until the 19th century especially for operating numerous mills, including sawmills and hammer mills and was one of the local factors in the industrialization of some Black Forest valleys. Since the 20th century, the Black Forest has seen the large-scale generation of electrical power using run-of-the-river power plants and pumped storage power stations. From 1914 to 1926, the Rudolf Fettweis Company was established in the Murg valley in the Northern Black Forest with the construction of the Schwarzenbach Dam. In 1932, the Schluchsee reservoir, with its new dam, became the upper basin of a pumped-storage power plant. In 2013 the association of the Southern Black Forest's Schluchseewerk owned five power plants with 14 storage tanks. At the Hornberg Basin topographical conditions allow an average head of water of 625 m to drive the turbines before it flows into the Wehra Reservoir. In the 21st century, in the wake of the Renewable Energy Sources Act, numerous smaller run-of-the-river power stations were re-opened or newly constructed. Notable people and residents Hans Jakob Christoffel von Grimmelshausen (1621/22–1676), German novelist; in 1665–67, he kept an inn in Gaisbach in the Black Forest while writing his famous picaresque novel Simplicius Simplicissimus (1669) Hans Thoma, born in Bernau (1839–1924), German painter Hermann Hesse, born in Calw (1877–1962), German poet and novelist Jürgen Klopp, football manager, who grew up in village of Glatten Martin Heidegger, German philosopher, who spent much of his time in Todtnauberg, where he wrote most of Being and Time.

British Columbia

British Columbia (commonly abbreviated as BC) is the westernmost province of Canada. Situated between the Pacific Ocean and the Rocky Mountains, the province has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains. British Columbia borders the province of Alberta to the east; the territories of Yukon to the north; the Northwest Territories to the northeast; the US states of Washington, Idaho and Montana to the south; and Alaska to the northwest. With an estimated population of over 5.5million as of 2023, it is Canada's third-most populous province. The capital of British Columbia is Victoria, while the province's largest city is Vancouver. Vancouver and its suburbs together make up the third-largest metropolitan area in Canada; with the 2021 census recording 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established in 1843, which gave rise to the city of Victoria, the capital of the Colony of Vancouver Island. The Colony of British Columbia (1858–1866) was subsequently founded by Richard Clement Moody, and by the Royal Engineers, Columbia Detachment, in response to the Fraser Canyon Gold Rush. Moody selected the site for and founded the mainland colony's capital New Westminster. The colonies of Vancouver Island and British Columbia were incorporated in 1866, subsequent to which Victoria became the united colony's capital. In 1871, British Columbia entered Confederation as the sixth province of Canada, in enactment of the British Columbia Terms of Union. British Columbia is a diverse and cosmopolitan province, drawing on a plethora of cultural influences from its British Canadian, European, and Asian diasporas, as well as the Indigenous population. Though the province's ethnic majority originates from the British Isles, many British Columbians also trace their ancestors to continental Europe, East Asia, and South Asia. Indigenous Canadians constitute about 6 percent of the province's total population. Christianity is the largest religion in the region, though the majority of the population is non-religious. English is the common language of the province, although Punjabi, Mandarin Chinese, and Cantonese also have a large presence in the Metro Vancouver region. The Franco-Columbian community is an officially recognized linguistic minority, and around one percent of British Columbians claim French as their mother tongue. British Columbia is home to at least 34 distinct Indigenous languages. Major sectors of British Columbia's economy include forestry, mining, filmmaking and video production, tourism, real estate, construction, wholesale, and retail. Its main exports include lumber and timber, pulp and paper products, copper, coal, and natural gas. British Columbia exhibits high property values and is a significant centre for maritime trade: the Port of Vancouver is the largest port in Canada and the most diversified port in North America. Although less than 5 percent of the province's territory is arable land, significant agriculture exists in the Fraser Valley and Okanagan due to the warmer climate. British Columbia is home to 45% of all publicly listed companies in Canada. Etymology The province's name was chosen by Queen Victoria, when the Colony of British Columbia (1858–1866), i.e., "the Mainland", became a British colony in 1858. It refers to the Columbia District, the British name for the territory drained by the Columbia River, in southeastern British Columbia, which was the namesake of the pre-Oregon Treaty Columbia Department of the Hudson's Bay Company. Queen Victoria chose British Columbia to distinguish what was the British sector of the Columbia District from the United States' ("American Columbia" or "Southern Columbia"), which became the Oregon Territory on August 8, 1848, as a result of the treaty. Ultimately, the Columbia in the name British Columbia is derived from the name of the Columbia Rediviva, an American ship which lent its name to the Columbia River and later the wider region; the Columbia in the name Columbia Rediviva came from the name Columbia for the New World or parts thereof, a reference to Christopher Columbus. The governments of Canada and British Columbia recognize as the French name for the province. Geography British Columbia is bordered to the west by the Pacific Ocean and the American state of Alaska, to the north by Yukon and the Northwest Territories, to the east by the province of Alberta, and to the south by the American states of Washington, Idaho, and Montana. The southern border of British Columbia was established by the 1846 Oregon Treaty, although its history is tied with lands as far south as California. British Columbia's land area is . British Columbia's rugged coastline stretches for more than , and includes deep, mountainous fjords and about 6,000 islands, most of which are uninhabited. It is the only province in Canada that borders the Pacific Ocean. British Columbia's capital is Victoria, located at the southeastern tip of Vancouver Island. Only a narrow strip of Vancouver Island, from Campbell River to Victoria, is significantly populated. Much of the western part of Vancouver Island and the rest of the coast is covered by temperate rainforest. The province's most populous city is Vancouver, which is at the confluence of the Fraser River and Georgia Strait, in the mainland's southwest corner (an area often called the Lower Mainland). By land area, Abbotsford is the largest city. Vanderhoof is near the geographic centre of the province. The Coast Mountains and the Inside Passage's many inlets provide some of British Columbia's renowned and spectacular scenery, which forms the backdrop and context for a growing outdoor adventure and ecotourism industry. 75 percent of the province is mountainous (more than above sea level); 60 percent is forested; and only about 5 percent is arable. The province's mainland away from the coastal regions is somewhat moderated by the Pacific Ocean. Terrain ranges from dry inland forests and semi-arid valleys, to the range and canyon districts of the Central and Southern Interior, to boreal forest and subarctic prairie in the Northern Interior. High mountain regions both north and south have subalpine flora and subalpine climate. The Okanagan wine area, extending from Vernon to Osoyoos at the United States border, is one of several wine and cider-producing regions in Canada. Other wine regions in British Columbia include the Cowichan Valley on Vancouver Island and the Fraser Valley. The Southern Interior cities of Kamloops and Penticton have some of the warmest and longest summer climates in Canada (while higher elevations are cold and snowy), although their temperatures are often exceeded north of the Fraser Canyon, close to the confluence of the Fraser and Thompson rivers, where the terrain is rugged and covered with desert-type flora. Semi-desert grassland is found in large areas of the Interior Plateau, with land uses ranging from ranching at lower altitudes to forestry at higher ones. The northern, mostly mountainous, two-thirds of the province is largely unpopulated and undeveloped, except for the area east of the Rockies, where the Peace River Country contains BC's portion of the Canadian Prairies, centred at the city of Dawson Creek. British Columbia is considered part of the Pacific Northwest and the Cascadia bioregion, along with the American states of Alaska, Idaho, (western) Montana, Oregon, Washington, and (northern) California. Climate Because of the many mountain ranges and rugged coastline, British Columbia's climate varies dramatically across the province. Coastal southern British Columbia has a mild, rainy oceanic climate, influenced by the North Pacific Current, which has its origins in the Kuroshio Current. Hucuktlis Lake on Vancouver Island receives an average of of rain annually, and some parts of the area are even classified as warm-summer Mediterranean, the northernmost occurrence in the world. Due to the blocking presence of successive mountain ranges, the climate of some of the interior valleys of the province (such as the Thompson, parts of the Fraser Canyon, the southern Cariboo and parts of the Okanagan) is semi-arid with certain locations receiving less than in annual precipitation. The annual mean temperature in the most populated areas of the province is up to , the mildest anywhere in Canada. The valleys of the Southern Interior have short winters with only brief bouts of cold or infrequent heavy snow, while those in the Cariboo, in the Central Interior, are colder because of increased altitude and latitude, but without the intensity or duration experienced at similar latitudes elsewhere in Canada. Outside of the driest valleys, the Southern and Central Interior generally have a humid continental climate with widely variable precipitation. For example, the average daily low in Prince George (roughly in the middle of the province) in January is . Small towns in the southern interior with high elevation such as Princeton are typically colder and snowier than cities in the valleys. Heavy snowfall occurs in all elevated mountainous terrain providing bases for skiers in both south and central British Columbia. Annual snowfall on highway mountain passes in the southern interior rivals some of the snowiest cities in Canada, and freezing rain and fog are sometimes present on such roads as well. This can result in hazardous driving conditions, as people are usually travelling between warmer areas such as Vancouver or Kamloops, and may be unaware that the conditions may be slippery and cold. Winters are generally severe in the Northern Interior which is generally in the subarctic climate zone, but even there, milder air can penetrate far inland. The coldest temperature in British Columbia was recorded in Smith River, where it dropped to on January 31, 1947, one of the coldest readings recorded anywhere in North America. Atlin in the province's far northwest, along with the adjoining Southern Lakes region of Yukon, get midwinter thaws caused by the Chinook effect, which is also common (and much warmer) in more southerly parts of the Interior. During winter on the coast, rainfall, sometimes relentless heavy rain, dominates because of consistent barrages of cyclonic low-pressure systems from the North Pacific. Average snowfall on the coast during a normal winter is between , but on occasion (and not every winter) heavy snowfalls with more than and well below freezing temperatures arrive when modified arctic air reaches coastal areas, typically for short periods, and can take temperatures below , even at sea level. Arctic outflow winds can occasionally result in wind chill temperatures at or even below .. While winters are very wet, coastal areas are generally milder and dry during summer under the influence of stable anti-cyclonic high pressure. Southern Interior valleys are hot in summer; for example, in Osoyoos, the July maximum temperature averages , making it the hottest month of any location in Canada; this hot weather sometimes spreads towards the coast or to the far north of the province. Temperatures often exceed in the lower elevations of valleys in the Interior during mid-summer, with the record high of being held in Lytton on June 29, 2021, during a record-breaking heat wave that year. The extended summer dryness often creates conditions that spark forest fires, from dry-lightning or man-made causes. Many areas of the province are often covered by a blanket of heavy cloud and low fog during the winter months, in contrast to abundant summer sunshine. Annual sunshine hours vary from 2200 near Cranbrook and Victoria to less than 1300 in Prince Rupert, on the North Coast just south of Southeast Alaska. The exception to British Columbia's wet and cloudy winters is during the El Niño phase. During El Niño events, the jet stream is much farther south across North America, making the province's winters milder and drier than normal. Winters are much wetter and cooler during the opposite phase, La Niña. Parks and protected areas There are 14 designations of parks and protected areas in the province that reflect the different administration and creation of these areas in a modern context. There are 141 ecological reserves, 35 provincial marine parks, 7 provincial heritage sites, 6 National Historic Sites of Canada, 4 national parks and 3 national park reserves. 12.5 percent of the province's area () is considered protected under one of the 14 different designations that includes over 800 distinct areas. British Columbia contains seven of Canada's national parks and National Park Reserves: Glacier National Park Gulf Islands National Park Reserve Gwaii Haanas National Park Reserve and Haida Heritage Site Kootenay National Park Mount Revelstoke National Park Pacific Rim National Park Reserve Yoho National Park British Columbia contains a large number of provincial parks, run by BC Parks under the aegis of the Ministry of Environment. British Columbia's provincial parks system is the second largest parks system in Canada, the largest being Canada's National Parks system. Another tier of parks in British Columbia are regional parks, which are maintained and run by the province's regional districts. The Ministry of Forests operates forest recreation sites. In addition to these areas, over of arable land are protected by the Agricultural Land Reserve. Fauna Much of the province is undeveloped, so populations of many mammalian species that have become rare in much of the United States still flourish in British Columbia. Watching animals of various sorts, including a very wide range of birds, has long been popular. Bears (grizzly, black—including the Kermode bear or spirit bear) live here, as do deer, elk, moose, caribou, big-horn sheep, mountain goats, marmots, beavers, muskrats, coyotes, wolves, mustelids (such as wolverines, badgers and fishers), cougars, eagles, ospreys, herons, Canada geese, swans, loons, hawks, owls, ravens, harlequin ducks, and many other sorts of ducks. Smaller birds (robins, jays, grosbeaks, chickadees, and so on) also abound. Murrelets are known from Frederick Island, a small island off the coast of Haida Gwaii. Many healthy populations of fish are present, including salmonids such as several species of salmon, trout, steelhead, and char. Besides salmon and trout, sport-fishers in BC also catch halibut, bass, and sturgeon. On the coast, harbour seals and river otters are common. Cetacean species native to the coast include the orca, humpback whale, grey whale, harbour porpoise, Dall's porpoise, Pacific white-sided dolphin and minke whale. Some endangered species in British Columbia are: Vancouver Island marmot, spotted owl, American white pelican, and badgers. Forests White spruce or Engelmann spruce and their hybrids occur in 12 of the 14 biogeoclimatic zones of British Columbia. Common types of trees present in BC's forests include western redcedar, yellow-cedar, Rocky Mountain juniper, lodgepole pine, ponderosa or yellow pine, whitebark pine, limber pine, western white pine, western larch, tamarack, alpine larch, white spruce, Engelmann spruce, Sitka spruce, black spruce, grand fir, Amabilis fir, subalpine fir, western hemlock, mountain hemlock, Douglas-fir, western yew, Pacific dogwood, bigleaf maple, Douglas maple, vine maple, arbutus, black hawthorn, cascara, Garry oak, Pacific crab apple, choke cherry, pin cherry, bitter cherry, red alder, mountain alder, paper birch, water birch, black cottonwood, balsam poplar, trembling aspen. Traditional plant foods First Nations peoples of British Columbia used plants for food, and to produce material goods like fuel and building products. Plant foods included berries, and roots like camas. Ecozones Environment Canada subdivides British Columbia into six ecozones: Pacific Marine Pacific Maritime Boreal Cordillera Montane Cordillera Taiga Plains Boreal Plains Ecozones. History Indigenous societies The area now known as British Columbia is home to First Nations groups that have a deep history with a significant number of indigenous languages. There are more than 200 First Nations in BC. Prior to contact (with non-Aboriginal people), human history is known from oral histories of First Nations groups, archaeological investigations, and from early records from explorers encountering societies early in the period. The arrival of Paleoindians from Beringia took place between 20,000 and 12,000 years ago. Hunter-gatherer families were the main social structure from 10,000 to 5,000 years ago. The nomadic population lived in non-permanent structures foraging for nuts, berries and edible roots while hunting and trapping larger and small game for food and furs. Around 5,000 years ago individual groups started to focus on resources available to them locally. Coast Salish peoples had complex land management practices linked to ecosystem health and resilience. Forest gardens on Canada's northwest coast included crabapple, hazelnut, cranberry, wild plum, and wild cherry species. Thus with the passage of time there is a pattern of increasing regional generalization with a more sedentary lifestyle. These indigenous populations evolved over the next 5,000 years across a large area into many groups with shared traditions and customs. To the northwest of the province are the peoples of the Na-Dene languages, which include the Athapaskan-speaking peoples and the Tlingit, who lived on the islands of southern Alaska and northern British Columbia. The Na-Dene language group is believed to be linked to the Yeniseian languages of Siberia. The Dene of the western Arctic may represent a distinct wave of migration from Asia to North America. The Interior of British Columbia was home to the Salishan language groups such as the Shuswap (Secwepemc), Okanagan and Athabaskan language groups, primarily the Dakelh (Carrier) and the Tsilhqot'in. The inlets and valleys of the British Columbia coast sheltered large, distinctive populations, such as the Haida, Kwakwaka'wakw and Nuu-chah-nulth, sustained by the region's abundant salmon and shellfish. These peoples developed complex cultures dependent on the western red cedar that included wooden houses, seagoing whaling and war canoes and elaborately carved potlatch items and totem poles. Contact with Europeans brought a series of devastating epidemics of diseases from Europe the people had no immunity to. The result was a dramatic population collapse, culminating in the 1862 Smallpox outbreak in Victoria that spread throughout the coast. European settlement did not bode well for the remaining native population of British Columbia. Colonial officials deemed colonists could make better use of the land than the First Nations people, and thus the land territory be owned by the colonists. To ensure colonists would be able to settle properly and make use of the land, First Nations were forcibly relocated onto reserves, which were often too small to support their way of life. By the 1930s, British Columbia had over 1500 reserves. Fur trade and colonial era Lands now known as British Columbia were added to the British Empire during the 19th century. Colonies originally begun with the support of the Hudson's Bay Company (Vancouver Island, the mainland) were amalgamated, then entered Confederation as British Columbia in 1871 as part of the Dominion of Canada. During the 1770s, smallpox killed at least 30 percent of the Pacific Northwest First Nations. This devastating epidemic was the first in a series; the 1862 Pacific Northwest smallpox epidemic killed about half to two-thirds of the native population of what became British Columbia. The arrival of Europeans began around the mid-18th century, as fur traders entered the area to harvest sea otters. While it is thought Sir Francis Drake may have explored the British Columbian coast in 1579, it was Juan Pérez who completed the first documented voyage, which took place in 1774. Juan Francisco de la Bodega y Quadra explored the coast in 1775. In doing so, Pérez and Quadra reasserted the Spanish claim for the Pacific coast, first made by Vasco Núñez de Balboa in 1513. The explorations of James Cook in 1778 and George Vancouver in 1792 and 1793 established British jurisdiction over the coastal area north and west of the Columbia River. In 1793, Sir Alexander Mackenzie was the first European to journey across North America overland to the Pacific Ocean, inscribing a stone marking his accomplishment on the shoreline of Dean Channel near Bella Coola. His expedition theoretically established British sovereignty inland, and a succession of other fur company explorers charted the maze of rivers and mountain ranges between the Canadian Prairies and the Pacific. Mackenzie and other explorers—notably John Finlay, Simon Fraser, Samuel Black, and David Thompson—were primarily concerned with extending the fur trade, rather than political considerations. In 1794, by the third of a series of agreements known as the Nootka Conventions, Spain conceded its claims of exclusivity in the Pacific. This opened the way for formal claims and colonization by other powers, including Britain, but because of the Napoleonic Wars, there was little British action on its claims in the region until later. The establishment of trading posts by the North West Company and the Hudson's Bay Company (HBC), effectively established a permanent British presence in the region. The Columbia District was broadly defined as being south of 54°40 north latitude, (the southern limit of Russian America), north of Mexican-controlled California, and west of the Rocky Mountains. It was, by the Anglo-American Convention of 1818, under the "joint occupancy and use" of citizens of the United States and subjects of Britain (which is to say, the fur companies). This co-occupancy was ended with the Oregon Treaty of 1846. The major supply route was the York Factory Express between Hudson Bay and Fort Vancouver. Some of the early outposts grew into settlements, communities, and cities. Among the places in British Columbia that began as fur trading posts are Fort St. John (established 1794); Hudson's Hope (1805); Fort Nelson (1805); Fort St. James (1806); Prince George (1807); Kamloops (1812); Fort Langley (1827); Fort Victoria (1843); Yale (1848); and Nanaimo (1853). Fur company posts that became cities in what is now the United States include Vancouver, Washington (Fort Vancouver), formerly the "capital" of Hudson's Bay operations in the Columbia District, Colville, Washington and Walla Walla, Washington (old Fort Nez Percés). With the amalgamation of the two fur trading companies in 1821, modern-day British Columbia existed in three fur trading departments. The bulk of the central and northern interior was organized into the New Caledonia district, administered from Fort St. James. The interior south of the Thompson River watershed and north of the Columbia was organized into the Columbia District, administered from Fort Vancouver on the lower Columbia River. The northeast corner of the province east of the Rockies, known as the Peace River Block, was attached to the much larger Athabasca District, headquartered in Fort Chipewyan, in present-day Alberta. Until 1849, these districts were a wholly unorganized area of British North America under the de facto jurisdiction of HBC administrators; however, unlike Rupert's Land to the north and east, the territory was not a concession to the company. Rather, it was simply granted a monopoly to trade with the First Nations inhabitants. All that was changed with the westward extension of American exploration and the concomitant overlapping claims of territorial sovereignty, especially in the southern Columbia Basin (within present day Washington and Oregon). In 1846, the Oregon Treaty divided the territory along the 49th parallel to the Strait of Georgia, with the area south of this boundary (excluding Vancouver Island and the Gulf Islands) transferred to sole American sovereignty. The Colony of Vancouver Island was created in 1849, with Victoria designated as the capital. New Caledonia, as the whole of the mainland rather than just its north-central Interior came to be called, continued to be an unorganized territory of British North America, "administered" by individual HBC trading post managers. Colony of British Columbia (1858–1866) With the Fraser Canyon Gold Rush in 1858, an influx of Americans into New Caledonia prompted the colonial office to designate the mainland as the Colony of British Columbia. When news of the Fraser Canyon Gold Rush reached London, Richard Clement Moody was hand-picked by the Colonial Office, under Sir Edward Bulwer-Lytton, to establish British order and to transform the newly established Colony of British Columbia into the British Empire's "bulwark in the farthest west" and "found a second England on the shores of the Pacific". Lytton desired to send to the colony "representatives of the best of British culture, not just a police force": he sought men who possessed "courtesy, high breeding and urbane knowledge of the world" and he decided to send Moody, whom the government considered to be the "English gentleman and British Officer" to lead the Royal Engineers, Columbia Detachment. Moody and his family arrived in British Columbia in December 1858, commanding the Royal Engineers, Columbia Detachment. He was sworn in as the first lieutenant governor of British Columbia and appointed Chief Commissioner of Lands and Works for British Columbia. On the advice of Lytton, Moody hired Robert Burnaby as his personal secretary. In British Columbia, Moody "wanted to build a city of beauty in the wilderness" and planned his city as an iconic visual metaphor for British dominance, "styled and located with the objective of reinforcing the authority of the crown and of the robe". Subsequent to the enactment of the Pre-emption Act of 1860, Moody settled the Lower Mainland. He selected the site and founded the new capital, New Westminster. He selected the site due to the strategic excellence of its position and the quality of its port. He was also struck by the majestic beauty of the site, writing in his letter to Blackwood, Lord Lytton "forgot the practicalities of paying for clearing and developing the site and the town" and the efforts of Moody's engineers were continuously hampered by insufficient funds, which, together with the continuous opposition of Governor James Douglas, whom Sir Thomas Frederick Elliot (1808 - 1880) described as 'like any other fraud', 'made it impossible for [Moody's] design to be fulfilled'. Moody and the Royal Engineers also built an extensive road network, including what would become Kingsway, connecting New Westminster to False Creek, the North Road between Port Moody and New Westminster, and the Cariboo Road and Stanley Park. He named Burnaby Lake after his private secretary Robert Burnaby and named Port Coquitlam's 400-foot "Mary Hill" after his wife. As part of the surveying effort, several tracts were designated "government reserves", which included Stanley Park as a military reserve (a strategic location in case of an American invasion). The Pre-emption Act did not specify conditions for distributing the land, so large parcels were snapped up by speculators, including by Moody himself. For this he was criticized by local newspapermen for land grabbing. Moody designed the first coat of arms of British Columbia. Port Moody is named after him. It was established at the end of a trail that connected New Westminster with Burrard Inlet to defend New Westminster from potential attack from the US. By 1862, the Cariboo Gold Rush, attracting an additional 5000 miners, was underway, and Douglas hastened construction of the Great North Road (commonly known now as the Cariboo Wagon Road) up the Fraser Canyon to the prospecting region around Barkerville. By the time of this gold rush, the character of the colony was changing, as a more stable population of British colonists settled in the region, establishing businesses, opening sawmills, and engaging in fishing and agriculture. With this increased stability, objections to the colony's absentee governor and the lack of responsible government began to be vocalized, led by the influential editor of the New Westminster British Columbian and future premier, John Robson. A series of petitions requesting an assembly were ignored by Douglas and the colonial office until Douglas was eased out of office in 1864. Finally, the colony would have both an assembly and a resident governor. Later gold rushes A series of gold rushes in various parts of the province followed, the largest being the Cariboo Gold Rush in 1862, forcing the colonial administration into deeper debt as it struggled to meet the extensive infrastructure needs of far-flung boom communities like Barkerville and Lillooet, which sprang up overnight. The Vancouver Island colony was facing financial crises of its own, and pressure to merge the two eventually succeeded in 1866, when the colony of British Columbia was amalgamated with the Colony of Vancouver Island to form the Colony of British Columbia (1866–1871), which was, in turn, succeeded by the present day province of British Columbia following the Canadian Confederation of 1871. Rapid growth and development The Confederation League, including such figures as Amor De Cosmos, John Robson, and Robert Beaven, led the chorus pressing for the colony to join Canada, which had been created out of three British North American colonies in 1867 (the Province of Canada, Nova Scotia and New Brunswick). Several factors motivated this agitation, including the fear of annexation to the United States, the overwhelming debt created by rapid population growth, the need for government-funded services to support this population, and the economic depression caused by the end of the gold rush. With the agreement by the Canadian government to extend the Canadian Pacific Railway to British Columbia and to assume the colony's debt, British Columbia became the sixth province to join Confederation on July 20, 1871. The borders of the province were not completely settled. The Treaty of Washington sent the Pig War San Juan Islands Border dispute to arbitration in 1871 and in 1903, the province's territory shrank again after the Alaska boundary dispute settled the vague boundary of the Alaska Panhandle. Population in British Columbia continued to expand as the province's mining, forestry, agriculture, and fishing sectors were developed. Mining activity was particularly notable throughout the Mainland, particularly in the Boundary Country, in the Slocan, in the West Kootenay around Trail, the East Kootenay (the southeast corner of the province), the Fraser Canyon, the Cariboo, the Omineca and the Cassiar, so much so a common epithet for the Mainland, even after provincehood, was "the Gold Colony". Agriculture attracted settlers to the fertile Fraser Valley, and cattle ranchers and later fruit growers came to the drier grasslands of the Thompson River area, the Cariboo, the Chilcotin, and the Okanagan. Forestry drew workers to the lush temperate rainforests of the coast, which was also the locus of a growing fishery. The completion of the railway in 1885 was a huge boost to the province's economy, facilitating the transportation of the region's considerable resources to the east. The milltown of Granville, known as Gastown, near the mouth of the Burrard Inlet was selected as the terminus of the railway, prompting the incorporation of the city as Vancouver in 1886. The completion of the Port of Vancouver spurred rapid growth, and in less than fifty years the city surpassed Winnipeg, Manitoba, as the largest in Western Canada. The early decades of the province were ones in which issues of land use—specifically, its settlement and development—were paramount. This included expropriation from First Nations people of their land, control over its resources, as well as the ability to trade in some resources (such as fishing). Establishing a labour force to develop the province was problematic from the start, and British Columbia was the locus of immigration from Europe, China, Japan and India. The influx of a non-European population stimulated resentment from the dominant ethnic groups, resulting in agitation (much of it successful) to restrict the ability of Asian people to immigrate to British Columbia through the imposition of a head tax. This resentment culminated in mob attacks against Chinese and Japanese immigrants in Vancouver in 1887 and 1907. The subsequent Komagata Maru incident in 1914, where hundreds of Indians were denied entry into Vancouver, was also a direct result of the anti-Asian resentment at the time. By 1923, almost all Chinese immigration had been blocked except for merchants, professionals, students and investors. Meanwhile, the province continued to grow. In 1914, the last spike of a second transcontinental rail line, the Grand Trunk Pacific, linking north-central British Columbia from the Yellowhead Pass through Prince George to Prince Rupert was driven at Fort Fraser. This opened up the North Coast and the Bulkley Valley region to new economic opportunities. What had previously been an almost exclusively fur trade and subsistence economy soon became a locus for forestry, farming, and mining. In World War I, the province responded strongly to the call to assist the British Empire against its German foes in French and Belgian battlefields. About 55,570 of the 400,000 British Columbian residents, the highest per-capita rate in Canada, responded to the military needs. Horseriders from the province's Interior region and First Nations soldiers made contributions to Vimy Ridge and other battles. About 6,225 men from the province died in combat. 1920s to 1940s When men returned from the First World War, they discovered the recently enfranchised women of the province voted for the prohibition of liquor in an effort to end the social problems associated with the hard-core drinking in the province was until the war. However, with pressure from veterans, prohibition was quickly relaxed so the "soldier and the working man" could enjoy a drink, but widespread unemployment among veterans was hardened by many of the available jobs being taken by European immigrants and disgruntled veterans organized a range of "soldier parties" to represent their interests, variously named Soldier-Farmer, Soldier-Labour, and Farmer-Labour Parties. These formed the basis of the fractured labour-political spectrum that would generate a host of fringe leftist and rightist parties, including those who would eventually form the Co-operative Commonwealth Federation and the early Social Credit splinter groups. The advent of prohibition in the United States created opportunities, and many found employment or at least profit in cross-border liquor smuggling. By the end of the 1920s, the end of prohibition in the U.S., combined with the onset of the Great Depression, plunged the province into economic destitution during the 1930s. Compounding the already dire local economic situation, tens of thousands of men from colder parts of Canada swarmed into Vancouver, creating huge hobo jungles around False Creek and the Burrard Inlet rail yards, including the old Canadian Pacific Railway mainline right-of-way through the heart of Downtown Vancouver. Increasingly desperate times led to intense political efforts, an occupation of the main Post Office at Granville and Hastings which was violently put down by the police and an effective imposition of martial law on the docks for almost three years due to the Battle of Ballantyne Pier. A Vancouver contingent for the On-to-Ottawa Trek was organized and seized a train, which was loaded with thousands of men bound for the capital but was met by a Gatling gun straddling train tracks at Mission. All the men were arrested and sent to work camps for the duration of the Depression. There were signs of an economic return towards the end of the 1930s, however, the onset of World War II transformed the national economy and ended the Depression. British Columbia has long taken advantage of its location on the Pacific Ocean to have close relations with East Asia and South Asia. These relations have often caused friction between cultures which has sometimes escalated into racist animosity towards those of Asian descent. This was manifest during the Second World War when many people of Japanese descent were relocated or interned in the Interior region of the province. Coalition and the post-war boom During the Second World War the mainstream BC Liberal and BC Conservative parties united in a formal coalition government under new Liberal leader John Hart, who replaced Duff Pattullo when the latter failed to win a majority in the 1941 election. While the Liberals won the most seats, they actually received fewer votes than the socialist Co-operative Commonwealth Federation (CCF). Pattullo was unwilling to form a coalition with the rival Conservatives led by Royal Maitland and was replaced by Hart, who formed a coalition cabinet made up of five Liberal and three Conservative ministers. The CCF was invited to join the coalition but refused. The pretext for continuing the coalition after the end of the Second World War was to prevent the CCF, which had won a surprise victory in Saskatchewan in 1944, from ever coming to power in British Columbia. The CCF's popular vote was high enough in the 1945 election that they were likely to have won three-way contests and could have formed government; however, the coalition prevented that by uniting the anti-socialist vote. In the post-war environment the government initiated a series of infrastructure projects, notably the completion of Highway 97 north of Prince George to the Peace River Block, a section called the John Hart Highway and also public hospital insurance. In 1947 the reins of the Coalition were taken by Byron Ingemar Johnson. The Conservatives had wanted their new leader Herbert Anscomb to be premier, but the Liberals in the Coalition refused. Johnson led the coalition to the highest percentage of the popular vote in British Columbia history (61 percent) in the 1949 election. This victory was attributable to the popularity of his government's spending programmes, despite rising criticism of corruption and abuse of power. During his tenure, major infrastructures continued to expand, such as the agreement with Alcan Aluminum to build the town of Kitimat with an aluminum smelter and the large Kemano Hydro Project. Johnson achieved popularity for flood relief efforts during the 1948 flooding of the Fraser Valley, which was a major blow to that region and to the province's economy. On February 13, 1950, a Convair B-36B crashed in northern British Columbia after jettisoning a Mark IV atomic bomb. This was the first such nuclear weapon loss in history. Increasing tension between the Liberal and Conservative coalition partners led the Liberal Party executive to vote to instruct Johnson to terminate the arrangement. Johnson ended the coalition and dropped his Conservative cabinet ministers, including Deputy Premier and Finance minister Herbert Anscomb, precipitating the general election of 1952. A referendum on electoral reform prior to this election had instigated an elimination ballot (similar to a preferential ballot), where voters could select second and third choices. The intent of the ballot, as campaigned for by Liberals and Conservatives, was that their supporters would list the rival party in lieu of the CCF, but this plan backfired when a large group of voters from all major parties, including the CCF, voted for the fringe Social Credit Party, who wound up with the largest number of seats in the House (19), only one seat ahead of the CCF, despite the CCF having 34.3 percent of the vote to Social Credit's 30.18 percent. The Social Credit Party, led by rebel former Conservative MLA W. A. C. Bennett, formed a minority government backed by the Liberals and Conservatives (with 6 and 4 seats respectively). Bennett began a series of fiscal reforms, preaching a new variety of populism as well as waxing eloquent on progress and development, laying the ground for a second election in 1953 in which the new Bennett regime secured a majority of seats, with 38 percent of the vote. Secure with that majority, Bennett returned the province to the first-past-the-post system thereafter, which is still in use. 1952–1960s With the election of the Social Credit Party, British Columbia embarked on a phase of rapid economic development. Bennett and his party governed the province for the next twenty years, during which time the government initiated an ambitious programme of infrastructure development, fuelled by a sustained economic boom in the forestry, mining, and energy sectors. During these two decades, the government nationalized British Columbia Electric and the British Columbia Power Company, as well as smaller electric companies, renaming the entity BC Hydro. West Kootenay Power and Light remained independent of BC Hydro, being owned and operated by Cominco, though tied into the regional power grid. By the end of the 1960s, several major dams had been begun or completed in—among others—the Peace, Columbia, and Nechako River watersheds (the Nechako Diversion to Kemano, was to supply power to the Alcan Inc. aluminum smelter at Kitimat, and was not part of the provincial power grid but privately owned). Major transmission deals were concluded, most notably the Columbia River Treaty between Canada and the United States. The province's economy was also boosted by unprecedented growth in the forest sector, as well as oil and gas development in the province's northeast. The 1950s and 1960s were also marked by development in the province's transportation infrastructure. In 1960, the government established BC Ferries as a crown corporation, to provide a marine extension of the provincial highway system, also supported by federal grants as being part of the Trans-Canada Highway system. That system was improved and expanded through the construction of new highways and bridges, and paving of existing highways and provincial roads. Vancouver and Victoria became cultural centres as poets, authors, artists, musicians, as well as dancers, actors, and haute cuisine chefs flocked to its scenery and warmer temperatures, with the cultural and entrepreneurial community bolstered by many Draft dodgers from the United States. Tourism also played a role in the economy. The rise of Japan and other Pacific economies was a boost to British Columbia's economy, primarily because of exports of lumber products and unprocessed coal and trees. Politically and socially, the 1960s brought a period of significant social ferment. The divide between the political left and right, which had prevailed in the province since the Depression and the rise of the labour movement, sharpened as so-called free enterprise parties coalesced into the de facto coalition represented by Social Credit—in opposition to the social democratic New Democratic Party (NDP), the successor to the Co-operative Commonwealth Federation. As the province's economy blossomed, so did labour-management tensions. Tensions emerged, also, from the counterculture movement of the late 1960s, of which Vancouver and Nanaimo were centres. The conflict between hippies and Vancouver mayor Tom Campbell was particularly legendary, culminating in the Gastown riots of 1971. By the end of the decade, with social tensions and dissatisfaction with the status quo rising, the Bennett government's achievements could not stave off its growing unpopularity. 1970s and 1980s On August 27, 1969, the Social Credit Party was re-elected in a general election for what would be Bennett's final term in power. At the start of the 1970s, the economy was quite strong because of rising coal prices and an increase in annual allowable cuts in the forestry sector, but BC Hydro reported its first loss, which was the beginning of the end for Bennett and the Social Credit Party. The Socreds were forced from power in the August 1972 election, paving the way for a provincial NDP government under Dave Barrett. Under Barrett, the large provincial surplus soon became a deficit, although changes to the accounting system makes it likely some of the deficit was carried over from the previous Social Credit regime and its "two sets of books", as W. A. C. Bennett had once referred to his system of fiscal management. The brief three-year ("Thousand Days") period of NDP governance brought several lasting changes to the province, most notably the creation of the Agricultural Land Reserve, intended to protect farmland from redevelopment, and the Insurance Corporation of British Columbia, a crown corporation charged with a monopoly on providing single-payer basic automobile insurance. Perceptions the government had instituted reforms either too swiftly or that were too far-reaching, coupled with growing labour disruptions led to the ouster of the NDP in the 1975 general election. Social Credit, under W.A.C. Bennett's son, Bill Bennett, was returned to office. Under the younger Bennett's government, 85 percent of the province's land base was transferred from government reserve to management by the Ministry of Forests, reporting of deputy ministers was centralized to the Premier's Office, and NDP-instigated social programs were rolled back, with then-human resources minister infamously demonstrating a golden shovel to highlight his welfare policy, although the new-era Social Credit Party also reinforced and backed certain others instigated by the NDP—notably the creation of the Resort Municipality of Whistler, whose special status including Sunday drinking, then an anomaly in BC. Also during the "MiniWac" regime (a reference to his father's acronym, W. A. C.) certain money-losing Crown-owned assets were "privatized" in a mass giveaway of shares in the British Columbia Resources Investment Corporation, "BCRIC", with the "Brick shares" soon becoming near-worthless. Towards the end of his tenure in power, Bennett oversaw the completion of several megaprojects meant to stimulate the economy and win votes – unlike most right-wing parties, British Columbia's Social Credit actively practiced government stimulation of the economy. Most notable of these was the winning of a world's fair for Vancouver, which came in the form of Expo 86, to which was tied the construction of the Coquihalla Highway and Vancouver's SkyTrain system. The Coquihalla Highway project became the subject of a scandal after revelations the premier's brother bought large tracts of land needed for the project before it was announced to the public, and also because of graft investigations of the huge cost overruns on the project. Both investigations were derailed in the media by a still further scandal, the Doman Scandal, in which the premier and millionaire backer Herb Doman were investigated for insider-trading and securities fraud. Nonetheless, the Socreds were re-elected in 1979 under Bennett, who led the party until 1986. As the province entered a sustained recession, Bennett's popularity and media image were in decline. On April 1, 1983, Premier Bennett overstayed his constitutional limits of power by exceeding the legal tenure of a government, and the lieutenant governor, Henry Pybus Bell-Irving, was forced to call Bennett to Government House to resolve the impasse, and an election was called for April 30, while in the meantime government cheques were covered by special emergency warrants as the Executive Council no longer had signing authority because of the constitutional crisis. Campaigning on a platform of moderation, Bennett won an unexpected majority. After several weeks of silence in the aftermath, a sitting of the House was finally called and in the speech from the throne, Social Credit instituted a programme of fiscal cutbacks dubbed "restraint", which had been a buzzword for moderation during the campaign. The programme included cuts to "motherhood" issues of the left, including the human rights branch, the offices of the Ombudsman and Rentalsman, women's programs, environmental and cultural programs, while still supplying mass capital infusions to corporate British Columbia. This sparked a backlash, with tens of thousands of people in the streets the next day after the budget speech, and through the course of a summer repeated large demonstrations of up to 100,000 people. This became known as the 1983 Solidarity Crisis, from the name of the Solidarity Coalition, a huge grassroots opposition movement mobilized, consisting of organized labour and community groups, with the British Columbia Federation of Labour forming a separate organization of unions, Operation Solidarity, under the direction of Jack Munro, then-president of the International Woodworkers of America (IWA), the most powerful of the province's resource unions. Tens of thousands participated in protests and many felt a general strike would be the inevitable result unless the government backed down from its policies they had claimed were only about restraint and not about recrimination against the NDP and the left. Just as a strike at Pacific Press ended, which had limited the political management of the public agenda by the publishers of the province's major papers, the movement collapsed after an apparent deal was struck by union leader and IWA president, Jack Munro and Premier Bennett. A tense winter of blockades at various job sites around the province ensued, as among the new laws were those enabling non-union labour to work on large projects and other sensitive labour issues, with companies from Alberta and other provinces brought in to compete with union-scale British Columbia companies. Despite the tension, Bennett's last few years in power were relatively peaceful as economic and political momentum grew on the megaprojects associated with Expo, and Bennett was to end his career by hosting Prince Charles and Lady Diana on their visit to open Expo 86. His retirement being announced, a Social Credit convention was scheduled for the Whistler Resort, which came down to a three-way shooting match between Bud Smith, the Premier's right-hand man but an unelected official, Social Credit party grande dame Grace McCarthy, and the charismatic but eccentric Bill Vander Zalm. Bill Vander Zalm became the new Social Credit leader when Smith threw his support to him rather than see McCarthy win, and led the party to victory in the election later that year. Vander Zalm was later involved in a conflict of interest scandal following the sale of Fantasy Gardens, a Christian and Dutch culture theme park built by the Premier, to Tan Yu, a Filipino Chinese gambling kingpin. There were also concerns over Yu's application to the government for a bank licence, and lurid stories from flamboyant realtor Faye Leung of a party in the "Howard Hughes Suite" on the top two floors of the Bayshore Inn, where Tan Yu had been staying, with reports of a bag of money in a brown paper bag passed from Yu to Vander Zalm during the goings-on. These scandals forced Vander Zalm's resignation, and Rita Johnston became premier of the province. Johnston presided over the end of Social Credit power, calling an election which reduced the party's caucus to only two seats, and the revival of the long-defunct British Columbia Liberal Party as Opposition to the victorious NDP under former Vancouver mayor Mike Harcourt. In 1988, David Lam was appointed as British Columbia's twenty-fifth lieutenant governor, and was the province's first lieutenant governor of Chinese origin. 1990s to present Johnston lost the 1991 general election to the NDP, under the leadership of Mike Harcourt, a former mayor of Vancouver. The NDP's unprecedented creation of new parkland and protected areas was popular and helped boost the province's growing tourism sector, although the economy continued to struggle against the backdrop of a weak resource economy. Housing starts and an expanded service sector saw growth overall through the decade, despite political turmoil. Harcourt ended up resigning over "Bingogate"—a political scandal involving the funnelling of charity bingo receipts into party coffers in certain ridings. Harcourt was not implicated, but he resigned nonetheless in respect of constitutional conventions calling for leaders under suspicion to step aside. Glen Clark, a former president of the BC Federation of Labour, was chosen the new leader of the NDP, which won a second term in 1996. More scandals dogged the party, most notably the fast ferry scandal involving the province trying to develop the shipbuilding industry in British Columbia. An allegation (never substantiated) that the premier had received a favour in return for granting a gaming licence led to Clark's resignation as premier. He was succeeded on an interim basis by Dan Miller who was in turn followed by Ujjal Dosanjh following a leadership convention. In the 2001 provincial election, Gordon Campbell's Liberals defeated the NDP, gaining 77 out of 79 total seats in the provincial legislature. Campbell instituted various reforms and removed some of the NDP's policies including scrapping the "fast ferries" project, lowering income taxes, and the controversial sale of BC Rail to Canadian National Railway. Campbell was also the subject of criticism after he was arrested for driving under the influence during a vacation in Hawaii, but he still managed to lead his party to victory in the 2005 provincial election against a substantially strengthened NDP opposition. Campbell won a third term in the 2009 provincial election, marking the first time in 23 years a premier has been elected to a third term. The province won a bid to host the 2010 Winter Olympics in Vancouver and Whistler. As promised in his 2002 re-election campaign, Vancouver Mayor Larry Campbell staged a non-binding civic referendum regarding the hosting of the Olympics. In February 2003, Vancouver's residents voted in a referendum accepting the responsibilities of the host city should it win its bid. Sixty-four percent of residents voted in favour of hosting the games. After the Olympic joy had faded, Campbell's popularity started to fall. His management style, the implementation of the Harmonized Sales Tax (HST) against election promises and the cancelling of the BC Rail corruption trial led to low approval ratings and loss of caucus support. He resigned in November 2010 and called on the party to elect a new leader. In early 2011, former deputy premier Christy Clark became leader of the Liberal Party. Though she was not a sitting MLA, she went on to win the seat left vacant by Campbell. For the next two years, she attempted to distance herself from the unpopularity of Campbell and forge an image for the upcoming 2013 election. Among her early accomplishments were raising the minimum wage, creating a new statutory holiday in February called "Family Day", and pushing the development of BC's liquefied natural gas industry. In the lead-up to the 2013 election, the Liberals lagged behind the NDP by a double-digit gap in the polls, but were able to achieve a surprise victory on election night, winning a majority and making Clark the first woman to lead a party to victory in a general election in BC. While Clark lost her seat to NDP candidate David Eby, she later won a by-election in the riding of Westside-Kelowna. Her government went on to balance the budget, implement changes to liquor laws and continue with the question of the proposed Enbridge Northern Gateway Pipelines. In the 2017 election, the NDP formed a minority government with the support of the Green Party through a confidence and supply agreement. The NDP and Green caucuses together controlled 44 seats, compared to the Liberals' 43. On July 18, 2017, NDP leader John Horgan was sworn in as the premier of British Columbia. He was the province's first NDP premier in 16 years. Clark resigned shortly thereafter, and Andrew Wilkinson was voted to become leader of the BC Liberals. In late 2020, Horgan called an early election. In the 2020 British Columbia general election, the NDP won 57 seats and formed a majority government, making Horgan the first NDP premier to be re-elected in the province. Wilkinson resigned as the leader of the BC Liberals two days later. British Columbia was significantly affected by demographic changes within Canada and around the world. Vancouver (and to a lesser extent some other parts of British Columbia) was a major destination for many of the immigrants from Hong Kong who left the former UK colony (either temporarily or permanently) in the years immediately prior to its handover to China. British Columbia has also been a significant destination for internal Canadian migrants. This has been the case throughout recent decades, because of its natural environment, mild climate and relaxed lifestyle, but has been particularly true during periods of economic growth. British Columbia has moved from approximately 10 percent of Canada's population in 1971 to approximately 13 percent in 2006. Trends of urbanization mean the Greater Vancouver area now includes 51 percent of the province's population, followed by Greater Victoria with 8 percent. These two metropolitan regions have traditionally dominated the demographics of BC. By 2018, housing prices in Vancouver were the second-least affordable in the world, behind only Hong Kong. Many experts point to evidence of money-laundering from mainland China as a contributing factor. The high price of residential real estate has led to the implementation of an empty homes tax, a housing speculation and vacancy tax, and a foreign buyers' tax on housing. The net number of people coming to BC from other provinces in 2016 was almost four times larger than in 2012. BC was the largest net recipient of interprovincial migrants in Canada in the first quarter of 2016 with half of the 5,000 people coming from Alberta. By 2021, the COVID-19 pandemic had had a major effect on the province, with over 2,000 deaths and 250,000 confirmed cases. However, the COVID-19 vaccine reduced the spread of the virus, with 78 percent of people in BC over the age of five having been fully vaccinated. In 2021, the unmarked gravesites of hundreds of Indigenous children were discovered at three former Indian residential schools (Kamloops, St. Eugene's Mission, Kuper Island). Demographics Population Statistics Canada's 2021 Canadian census recorded a population of 5,000,879 — making British Columbia Canada's third-most populous province after Ontario and Quebec. Cities Half of all British Columbians live in the Metro Vancouver Regional District, which includes Vancouver, Surrey, Burnaby, Richmond, Coquitlam, Langley (district municipality), Delta, North Vancouver (district municipality), Maple Ridge, New Westminster, Port Coquitlam, North Vancouver (city), West Vancouver, Port Moody, Langley (city), White Rock, Pitt Meadows, Bowen Island, Anmore, Lions Bay, and Belcarra, with adjacent unincorporated areas (including the University Endowment Lands) represented in the regional district as the electoral area known as Greater Vancouver Electoral Area A. The metropolitan area has seventeen Indian reserves, but they are outside of the regional district's jurisdiction and are not represented in its government. The second largest concentration of British Columbia population is at the southern tip of Vancouver Island, which is made up of the 13 municipalities of Greater Victoria, Victoria, Saanich, Esquimalt, Oak Bay, View Royal, Highlands, Colwood, Langford, Central Saanich/Saanichton, North Saanich, Sidney, Metchosin, Sooke, which are part of the Capital Regional District. The metropolitan area also includes several Indian reserves (the governments of which are not part of the regional district). Almost half of the Vancouver Island population is in Greater Victoria. Cultural origins British Columbia is the most diverse province in Canada; as of 2021, the province had the highest proportion of visible minorities in the country. The five largest pan-ethnic groups in the province are Europeans (60 percent), East Asians (14 percent), South Asians (10 percent), Indigenous (6 percent) and Southeast Asians (5 percent). Visible minorities and Indigenous peoples In 2021, 34.4 percent of the population consisted of visible minorities and 5.9 percent of the population was Indigenous, mostly of First Nations and Métis descent. Religion According to the 2021 census, religious groups in British Columbia included: Irreligion (2,559,250 persons or 52.1%) Christianity (1,684,870 persons or 34.3%) Sikhism (290,870 persons or 5.9%) Islam (125,915 persons or 2.6%) Buddhism (83,860 persons or 1.7%) Hinduism (81,320 persons or 1.7%) Judaism (26,850 persons or 0.5%) Indigenous spirituality (11,570 persons or 0.2%) Other (51,440 persons or 1.0%) Language As of the 2021 Canadian Census, the ten most spoken languages in the province included English (4,753,280 or 96.69%), French (327,350 or 6.66%), Punjabi (315,000 or 6.41%), Mandarin (312,625 or 6.36%), Cantonese (246,045 or 5.01%), Spanish (143,900 or 2.93%), Hindi (134,950 or 2.75%), Tagalog (133,780 or 2.72%), German (84,325 or 1.72%), and Korean (69,935 or 1.42%). The question on knowledge of languages allows for multiple responses. Of the 4,648,055 population counted by the 2016 census, 4,598,415 people completed the section about language. Of these, 4,494,995 gave singular responses to the question regarding their first language. The languages most commonly reported were the following: While these languages all reflect the last centuries of colonialism and recent immigration, British Columbia is home to 34 Indigenous languages. They are spoken by about 6000 people in total, with 4000 people fluent in their Indigenous languages. They are members of the province's First Nations. One of the main Indigenous languages in BC is Kwakʼwala, the language of the Kwakwakaʼwakw First Nations. Economy BC's economy is diverse, with service-producing industries accounting for the largest portion of the province's GDP. It is the terminus of two transcontinental railways, and the site of 27 major marine cargo and passenger terminals. Though less than 5 percent of its vast land is arable, the province is agriculturally rich (particularly in the Fraser and Okanagan valleys), because of milder weather near the coast and in certain sheltered southern valleys. Its climate encourages outdoor recreation and tourism, though its economic mainstay has long been resource extraction, principally logging, farming, and mining. Vancouver, the province's largest city, serves as the headquarters of many western-based natural resource companies. It also benefits from a strong housing market and a per capita income well above the national average. While the coast of British Columbia and some valleys in the south-central part of the province have mild weather, the majority of its land mass experiences a cold-winter-temperate climate similar to the rest of Canada. The Northern Interior region has a subarctic climate with very cold winters. The climate of Vancouver is by far the mildest winter climate of the major Canadian cities, with nighttime January temperatures averaging above the freezing point. British Columbia has a history of being a resource dominated economy, centred on the forestry industry but also with fluctuating importance in mining. Employment in the resource sector has fallen steadily as a percentage of employment, and new jobs are mostly in the construction and retail/service sectors. It now has the highest percentage of service industry jobs in the west, constituting 72 percent of industry (compared to 60 percent Western Canadian average). The largest section of this employment is in finance, insurance, real estate and corporate management; however, many areas outside of metropolitan areas are still heavily reliant on resource extraction. With its film industry known as Hollywood North, the Vancouver region is the third-largest feature film production location in North America, after Los Angeles and New York City. The economic history of British Columbia is replete with tales of dramatic upswings and downswings, and this boom and bust pattern has influenced the politics, culture and business climate of the province. Economic activity related to mining in particular has widely fluctuated with changes in commodity prices over time, with documented costs to community health. In 2020, British Columbia had the third-largest GDP in Canada, with a GDP of $309 billion and a GDP per capita of $60,090. British Columbia's debt-to-GDP ratio is edging up to 15.0 percent in fiscal year 2019–20, and it is expected to reach 16.1 percent by 2021–22. British Columbia's economy experienced strong growth in recent years with a total growth rate of 9.6% from 2017 to 2021, a growth rate that was second in the country. Government and politics The lieutenant governor, Janet Austin, is the Crown's representative in the province. During the absence of the lieutenant governor, the Governor in Council (federal Cabinet) may appoint an administrator to execute the duties of the office. This is usually the chief justice of British Columbia. British Columbia is divided into regional districts as a means to better enable municipalities and rural areas to work together at a regional level. British Columbia has an 87-member elected Legislative Assembly, elected by the plurality voting system, though from 2003 to 2009 there was significant debate about switching to a single transferable vote system called BC-STV. The government of the day appoints ministers for various portfolios, what are officially part of the Executive Council, of whom the premier is chair. The province is currently governed by the British Columbia New Democratic Party (BC NDP) under Premier David Eby. The 2017 provincial election saw the Liberal Party take 43 seats, the NDP take 41, and the British Columbia Green Party take 3. No party met the minimum of 44 seats for a majority, therefore leading to the first minority government since 1953. Following the election, the Greens entered into negotiations with both the Liberals and NDP, eventually announcing they would support the current NDP minority. Previously, the right-of-centre British Columbia Liberal Party governed the province for 16 years between 2001 and 2017, and won the largest landslide election in British Columbia history in 2001, with 77 of 79 seats. The legislature became more evenly divided between the Liberals and NDP following the 2005 (46 Liberal seats of 79) and 2009 (49 Liberal seats of 85) provincial elections. The NDP and its predecessor the Co-operative Commonwealth Federation (CCF) have been the main opposition force to right-wing parties since the 1930s and have ruled with majority governments in 1972–1975 and 1991–2001. The Green Party plays a larger role in the politics of British Columbia than Green parties do in most other jurisdictions in Canada. After a breakthrough election in 2001 (12.39 percent), the party's vote share declined (2005 – 9.17 percent, 2009 – 8.09 percent, 2013 – 8.13 percent) before increasing again to a record high of 16.84 percent at the 2017 election. The British Columbia Liberal Party is not related to the federal Liberal Party and does not share the same ideology. Instead, the BC Liberal party is a rather diverse coalition, made up of the remnants of the Social Credit Party, many federal Liberals, federal Conservatives, and those who would otherwise support right-of-centre or free enterprise parties. Historically, there have commonly been third parties present in the legislature (including the Liberals themselves from 1952 to 1975); the BC Green Party are the current third party in British Columbia, with three seats in the legislature. Prior to the rise of the Liberal Party, British Columbia's main political party was the British Columbia Social Credit Party which ruled British Columbia for 20 continuous years. While sharing some ideology with the current Liberal government, they were more right-wing although undertook nationalization of various important monopolies, notably BC Hydro and BC Ferries. British Columbia is known for having politically active labour unions who have traditionally supported the NDP or its predecessor, the CCF. British Columbia's political history is typified by scandal and a cast of colourful characters, beginning with various colonial-era land scandals and abuses of power by early officials (such as those that led to McGowan's War in 1858–59). Notable scandals in Social Credit years included the Robert Bonner Affair and the Fantasy Gardens scandal which forced Premier Bill Vander Zalm to resign and ended the Social Credit era. NDP scandals included Bingogate, which brought down NDP Premier Mike Harcourt, and the alleged scandal named Casinogate which drove NDP Premier Glen Clark to resign. A variety of scandals plagued the 2001–2017 Liberal government, including Premier Gordon Campbell's arrest for drunk driving in Maui and the resignation of various cabinet ministers because of conflict-of-interest allegations. A raid on the Parliament Buildings on December 28, 2003, in Victoria, including the Premier's Office, resulted in charges only for ministerial aides, although key cabinet members from the time have since resigned. The case, currently in preliminary hearings in the courts and relating to the sale of BC Rail to CN Rail, may not reach trial because of the mass of evidence and various procedural problems. Campbell eventually resigned in late 2010 due to opposition to his government's plan to introduce a Harmonized Sales Tax (HST) and was replaced by Christy Clark as premier in a 2011 BC Liberal leadership election. British Columbia is underrepresented in the Senate of Canada, leading Premier Christy Clark to refuse to cooperate with the federal government's reforms for senate appointments to be made based on the recommendations of a new advisory board that would use non-partisan criteria. Hours after that plan was unveiled in Ottawa on December 3, 2015, Clark issued a statement that it did "not address what's been wrong with the Senate since the beginning". The imbalance in representation in that House is apparent when considering population size. The six senators from BC constitute only one for every 775,000 people vs. one for every 75,000 in P.E.I. which has four senators. Nova Scotia and New Brunswick have much smaller populations than BC, yet each has ten senators according to a Global News summary. Correcting this imbalance would require a constitutional amendment, but that is unlikely to be supported by the Atlantic provinces. Official symbols The government of British Columbia has designated several official symbols: Flag: Flag of British Columbia Coat of arms: Coat of arms of British Columbia Floral emblem: Pacific dogwood Mineral emblem: Jade Tree emblem: Western red cedar Bird emblem: Steller's jay Mammal emblem: "Spirit" or Kermode bear Fish emblem: Pacific salmon Tartan emblem: British Columbia Tartan Transportation Transportation played a huge role in British Columbia's history. The Rocky Mountains and the ranges west of them constituted a significant obstacle to overland travel until the completion of the transcontinental railway in 1885. The Peace River Canyon through the Rocky Mountains was the route the earliest explorers and fur traders used. Fur trade routes were only marginally used for access to British Columbia through the mountains. Travel from the rest of Canada before 1885 meant the difficulty of overland travel via the United States, around Cape Horn or overseas from Asia. Nearly all travel and freight to and from the region occurred via the Pacific Ocean, primarily through the ports of Victoria and New Westminster. Until the 1930s, rail was the only means of overland travel to and from the rest of Canada; travellers using motor vehicles needed to journey through the United States. With the construction of the Inter-Provincial Highway in 1932 (now known as the Crowsnest Pass Highway), and later the Trans-Canada Highway, road transportation evolved into the preferred mode of overland travel to and from the rest of the country. , the number of electric vehicles sold in British Columbia (as a percentage of total vehicle sales) was the highest of any Canadian province or U.S. state. Roads and highways Because of its size and rugged, varying topography, British Columbia requires thousands of kilometres of provincial highways to connect its communities. British Columbia's roads systems were notoriously poorly maintained and dangerous until a concentrated programme of improvement was initiated in the 1950s and 1960s. There are now freeways in Greater Victoria, the Lower Mainland, and Central Interior of the province. Much of the rest of the province, where traffic volumes are generally low, is accessible by well-maintained generally high-mobility two-lane arterial highways with additional passing lanes in mountainous areas and usually only a few stop-controlled intersections outside the main urban areas. A couple of busy intercity corridors outside Greater Vancouver feature more heavily signalized limited-mobility arterial highways that are mostly four-lane and often divided by portable median traffic barriers. Highway 1 on Vancouver Island and Highway 97 through the Okanagan Valley are medium- to high-volume roadways with variable posted speeds that range from to maximums just slightly lower than the principal grade-separated highways. Numerous traffic lights operate in place of interchanges on both arterials as long-term cost-cutting measures. Signalization along both these highways is heaviest through urban areas and along inter-urban sections where traffic volumes are similar to and sometimes higher than the freeways, but where funding is not available for upgrades to interchanges or construction of high-mobility alternative routes or bypasses. The building and maintenance of provincial highways is the responsibility of the British Columbia Ministry of Transportation and Infrastructure. There are only five major routes to the rest of Canada. From south to north they are: BC Highway 3 through the Crowsnest Pass, the Vermilion Pass (Highway 93 in both British Columbia and Alberta), the Kicking Horse Pass, the latter being used by the Trans-Canada Highway entering Alberta through Banff National Park, the Yellowhead Highway (16) through Jasper National Park, and Highway 2 through Dawson Creek. There are also several highway crossings to the adjoining American states of Washington, Idaho, and Montana. The longest highway is Highway 97, running from the British Columbia-Washington border at Osoyoos north to Watson Lake, Yukon and which includes the British Columbia portion of the Alaska Highway. Public transit Prior to 1979, surface public transit in the Vancouver and Victoria metropolitan areas was administered by BC Hydro, the provincially owned electricity utility. Subsequently, the province established BC Transit to oversee and operate all municipal transportation systems. In 1998, the Greater Vancouver Transportation Authority, now TransLink, a separate authority for routes within the Greater Vancouver Regional District, was established. Some smaller island communities, such as Gabriola Island and, formerly, Pender Island operate routes independent of BC Transit or TransLink. BC Transit has recently expanded to provide intercity routes, particularly in the Northern region of British Columbia. Other intercity routes were introduced connecting southern communities in preparation of the cancellation of Greyhound Canada's pullout from Western Canada, though options for intercity bus travel are still extremely limited. Public transit in British Columbia consists mainly of diesel buses, although Vancouver is also serviced by a fleet of trolley buses. Several experimental buses are being tested such as hybrid buses that have both gasoline and electric engines. Additionally, there are CNG-fuelled buses being tested and used in Nanaimo and Kamloops systems. British Columbia also tested a fleet of Hydrogen-fuelled buses for the Vancouver-Whistler Winter Olympics in 2010. TransLink operates SkyTrain, an automated metro system serving the cities of Vancouver, Burnaby, New Westminster, Surrey, Richmond, Coquitlam, and Port Moody. In 2009, the Canada Line SkyTrain was completed, linking Vancouver International Airport and the city of Richmond to downtown Vancouver bringing the total to three operating metro lines. A new extension to Coquitlam and Port Moody (the Evergreen Extension of the Millennium Line) was completed in December 2016. Construction of an extension of the Millennium Line westwards through Vancouver to Arbutus Street began in February 2021, with future plans to extend the line farther west from Arbutus station to the University of British Columbia. Fare gates have been added to all existing stations, though in the past, SkyTrain used a proof of payment honour system. In the capital city of Victoria, BC Transit and the provincial government's infrastructure ministry are working together to create a bus rapid transit from the Westshore communities to downtown Victoria. In Kamloops, there is a bus rapid transit GPS trial underway to see how bus rapid transit affects smaller cities, rather than larger ones, like Victoria and Vancouver. Rail Rail development expanded greatly in the decades after the Canadian Pacific Railway was completed, in 1885, and was the chief mode of long-distance surface transportation until the expansion and improvement of the provincial highways system began in the 1950s. Two major routes through the Yellowhead Pass competed with the Canadian Pacific Railway – the Grand Trunk Pacific, terminating at Prince Rupert, and the Canadian Northern Railway, terminating at Vancouver. The British Columbia Electric Railway provided rail services in Victoria and Vancouver between the nineteenth century and mid twentieth century. The Pacific Great Eastern line supplemented this service, providing a north–south route between interior resource communities and the coast. The Pacific Great Eastern (later known as British Columbia Railway and now owned by Canadian National Railway) connects Fort St James, Fort Nelson, and Tumbler Ridge with North Vancouver. The E&N Railway, rebranded as Southern Railway of Vancouver Island, formerly served the commercial and passenger train markets of Vancouver Island. Service along the route is now minimal. Vancouver Island was also host to the last logging railway in North America until its closure in 2017. Current passenger services in British Columbia are limited. Via Rail Canada operates 10 long-distance trains per week on two lines. Local services are limited to two regions, with TransLink providing rapid transit and commuter services in the Lower Mainland and by the Seton Lake Indian Band South of Lillooet with the Kaoham Shuttle. Amtrak runs international passenger service between Vancouver, Seattle, and intermediate points. Several heritage railways operate within the province, including the White Pass & Yukon Route that runs between Alaska and the Yukon via British Columbia. Water BC Ferries was established as a provincial crown corporation in 1960 to provide passenger and vehicle ferry service between Vancouver Island and the Lower Mainland as a cheaper and more reliable alternative to the service operated by the Canadian Pacific Railway and other private operators. It now operates 25 routes among the islands of British Columbia, as well as between the islands and the mainland. Ferry service to Washington is offered by the Washington State Ferries (between Sidney and Anacortes) and Black Ball Transport (between Victoria and Port Angeles, Washington). Ferry service over inland lakes and rivers is provided by the Ministry of Transportation and Infrastructure. Various other coastal ferries are operated privately. Commercial ocean transport is of vital importance. Major ports are at Vancouver, Roberts Bank (near Tsawwassen), Prince Rupert, and Victoria. Vancouver, Victoria, and Prince Rupert are also major ports of call for cruise ships. In 2007, a large maritime container port was opened in Prince Rupert with an inland sorting port in Prince George. Air There are over 200 airports throughout British Columbia, the major ones being the Vancouver International Airport, the Victoria International Airport, the Kelowna International Airport, and the Abbotsford International Airport, the first three of which each served over 1,000,000 passengers in 2005. , Vancouver International Airport is the 2nd busiest airport in the country and the second biggest International Gateway on the west coast (after Los Angeles) with an estimated 26.4 million travellers passing through in 2019. Arts and culture Visual arts The earliest known visual art produced in the Pacific Northwest, and what would become British Columbia, was by First Nations such as the Coast Salish, Haida, Heiltsuk, and Tsimshian, among others. Such Indigenous work comes particularly in the form of woodcarving, as seen in totem poles, transformation masks, and canoes, as well as textile arts like Chilkat weaving and button blankets. Traditional Indigenous art of the Pacific Northwest is typically distinguished by the formline style, which is defined as "continuous, flowing, curvilinear lines that turn, swell and diminish in a prescribed manner. They are used for figure outlines, internal design elements and in abstract compositions." Western styles and forms were introduced to the region through the establishment of British North American settlements in the late 18th century. Notable English-Canadian artists of 19th and early 20th century British Columbia include architect Francis Rattenbury, designer James Blomfield, and painter Emily Carr. Vancouver's art scene was dominated by lyrical abstraction and surrealist landscape painting in the mid-20th century through such artists as B. C. Binning, Jack Shadbolt, Gordon A. Smith, Takao Tanabe, Don Jarvis, and Toni Onley. In the following decades, the city would undergo more artistic diversification with the emergence of conceptual art, communication art, video art, and performance art. The Vancouver School of conceptual photography encompasses a cohort of Vancouver-based artists who gained notoriety in the 1980s. This school is generally considered to include artists Jeff Wall, Ian Wallace, Ken Lum, Roy Arden, Stan Douglas, and Rodney Graham. Vancouver maintains roughly 350 works of outdoor public art. Some notable works include A-maze-ing Laughter, Digital Orca, Girl in a Wetsuit, Angel of Victory, The Birds, and the Brockton Point totem poles. Performing arts British Columbia is home to the Vancouver Opera, the City Opera of Vancouver, Ballet BC, contemporary dance companies Holy Body Tattoo, Kidd Pivot, Mascall Dance Society, and butoh dance troupe Kokoro Dance. It is also the home province for a plethora of independent theatre companies, including the Arts Club Theatre Company, the Shakespearean Bard on the Beach, and Theatre Under the Stars. Performing arts venues include the Queen Elizabeth Theatre, the Orpheum Theatre, and the Royal Theatre, among others. Music British Columbia is the third largest music-producing province in Canada and the local music industry generates an estimated yearly revenue of $265million. The province is home to the Vancouver Symphony Orchestra, the Okanagan Symphony Orchestra, the Vancouver Metropolitan Orchestra, the Vancouver Youth Symphony Orchestra, the Richmond Delta Youth Orchestra, and the Victoria Symphony. Some important popular music acts include bands such as Spirit of the West, Theory of a Deadman, Trooper, Gob, and The New Pornographers, and solo artists such as Bryan Adams, Carly Rae Jepsen, Mac DeMarco, Michael Bublé, Nelly Furtado, and Diana Krall. Music festivals include the Squamish Valley Music Festival, Shambhala Music Festival, and Pemberton Music Festival. Cuisine British Columbian cuisine is commonly associated with healthy living, fusion, fresh local ingredients, and innovation. It can be divided into two broadly-defined traditions: cuisine associated with the west coast, which incorporates a variety of seafood elements, and cuisine associated with the interior of the province, which embraces local game meat, farm-to-table produce, and methods of curing and smoking. Seafood is an important staple of the province's local food culture due to its proximity to the Pacific Ocean, as well as the region's numerous rivers and lakes. BC is known for several unique dishes and is a producer of fruit, wine, and cheese. Seafoods of British Columbia include sushi (BC roll, dynamite roll, California roll), dungeness crab (boiled, tacos), spot prawns, wild pacific salmon (smoked, candied, teriyaki, chowder, sandwich) , and halibut (baked, lemon ginger), as well as delicacies like white sturgeon caviar and geoduck British Columbia is also home to numerous unique non-seafood culinary staples. Some dishes include Doukhobour borscht, Salt Spring Island lamb, Japadog street food, and Butter chicken pizza. Some unique pastries include apple cranberry cinnamon buns, Nanaimo bars, and Victoria creams. British Columbia also produces several distinct local cheeses, such as kabritt, Castle Blue, and Comox Brie. The London Fog tea latte was invented in Vancouver and remains a popular beverage among coffee shops in the Pacific Northwest and Western Canada; it is referred to as a "Vancouver Fog" in Scotland. The Okanagan produces many unique fruits originating from the region, including Ambrosia and Spartan apples, Stella and Skeena cherries, and Corontation grapes. Other fruits grown in the province include peaches, pears, plums, apricots, strawberries, blackberries, cranberries, and loganberries. British Columbia is renowned for its wine production. The primary wine-producing regions include the Okanagan, the Similkameen Valley, Vancouver Island, the Gulf Islands, and the Fraser Valley. As of November 2014, there are 280 licensed grape wineries and 929 vineyards. Outdoor life and athletics Given its varied mountainous terrain and its coasts, lakes, rivers, and forests, British Columbia has long been enjoyed for pursuits like hiking and camping, rock climbing and mountaineering, hunting and fishing. Water sports, both motorized and non-motorized, are enjoyed in many places. Sea kayaking opportunities abound on the British Columbia coast with its fjords. Whitewater rafting and kayaking are popular on many inland rivers. Sailing and sailboarding are widely enjoyed. In winter, cross-country and telemark skiing are much enjoyed, and in recent decades high-quality downhill skiing has been developed in the Coast Mountain range and the Rockies, as well as in the southern areas of the Shuswap Highlands and the Columbia Mountains. Snowboarding has mushroomed in popularity since the early 1990s. The 2010 Winter Olympics downhill events were held in Whistler Blackcomb area of the province, while the indoor events were conducted in the Vancouver area. In Vancouver and Victoria (as well as some other cities), opportunities for joggers and bicyclists have been developed. Cross-country bike touring has been popular since the ten-speed bike became available many years ago. Since the advent of the more robust mountain bike, trails in more rugged and wild places have been developed for them. A 2016 poll on global biking website Pinkbike rated BC as the top destination mountain bikers would like to ride. Some of the province's retired rail beds have been converted and maintained for hiking, biking, and cross-country skiing. Longboarding is also a popular activity because of the hilly geography of the region. Horseback riding is enjoyed by many British Columbians. Opportunities for trail riding, often into especially scenic areas, have been established for tourists in numerous areas of the province. British Columbia also has strong participation levels in many other sports, including golf, tennis, soccer, hockey, Canadian football, rugby union, lacrosse, baseball, softball, basketball, curling, disc golf, Ultimate and figure skating. British Columbia has produced many outstanding athletes, especially in aquatic and winter sports. Consistent with both increased tourism and increased participation in diverse recreations by British Columbians has been the proliferation of lodges, chalets, bed and breakfasts, motels, hotels, fishing camps, and park-camping facilities in recent decades. In certain areas, there are businesses, non-profit societies, or municipal governments dedicated to promoting ecotourism in their region. A number of British Columbia farmers offer visitors to combine tourism with farm work, for example, through the WWOOF Canada program. Sports Education K-12 education British Columbia is home to a comprehensive education system consisting of public schools and independent schools that is overseen by the provincial Ministry of Education. The public school system is divided in 59 anglophone school districts and one francophone school district, the Conseil scolaire francophone de la Colombie-Britannique, which operates French-language public schools throughout the province. The anglophone school districts are governed by school board trustees who are directly elected by the school district's residents. Although 86 percent of students are enrolled in the public school system, British Columbia has one of the highest shares of independent school enrolment among Canadian province, at 14 percent of the student population, due to its relatively generous funding model; most independent schools receive 50 percent of the operating funding that their public counterparts receive from the government. A very small percentage (less than 1 percent) of students are home schooled. Like most other provinces in Canada, education is compulsory from ages 6 to 16 (grades 1–10), although the vast majority of students remain in school until they graduate from high school (grade 12) at the age of 18. In order to graduate with a graduation certificate, known as a Dogwood Diploma in BC, students must take a minimum of 80 course credits during grades 10 to 12. These credits include a variety of required courses (e.g. in language arts, social studies, mathematics, and science), as well as elective courses. Academic achievement in British Columbia is relatively good, although it has been slipping in recent years by some measures. In 2020, 86 percent of students in British Columbia graduated from high school within six years of entering grade 8. According to the 2018 Programme for International Student Assessment (PISA) scores, students in British Columbia scored the second highest in reading ability, fourth highest in mathematic prowess, and fourth highest in science knowledge of the 10 Canadian provinces, although these scores have declined significantly since the 2000 and 2015 assessments. International students In September 2014, there were 11,000 international students in BC public K-12 schools and about 3,000 international students in other BC K-12 schools. Higher education British Columbia has diverse array of higher educational institutions, ranging from publicly funded universities, colleges, and institutes, to private universities, colleges, seminaries, and career institutes. Public institutions receive approximately half of their funding from grants from the provincial government, with the remaining revenue stemming from tuition charges and philanthropic donations. Each post-secondary institution sets its own admission requirements, although the standard requirement is the completion of high school. Public universities and colleges include: University of British Columbia Simon Fraser University University of Victoria University of Northern British Columbia Vancouver Island University British Columbia Institute of Technology Kwantlen Polytechnic University Thompson Rivers University Emily Carr University of Art and Design Royal Roads University Capilano University University of the Fraser Valley Douglas College Camosun College Langara College Selkirk College College of New Caledonia College of the Rockies Okanagan College Coast Mountain College Justice Institute of BC British Columbia is also home to 11 private colleges and universities located throughout the province, including: Quest University Trinity Western University Alexander College University Canada West Columbia College Coquitlam College Tamwood International College Ashton College Blanche Macdonald Vanwest College Two American universities (Fairleigh Dickinson University and Northeastern University) also have degree-granting campuses located in Vancouver.

The Buddha

Siddhartha Gautama, most commonly referred to as the Buddha ('the awakened'), was a wandering ascetic and religious teacher who lived in South Asia during the 6th or 5th century BCE and founded Buddhism. According to Buddhist tradition, he was born in Lumbini, in what is now Nepal, to royal parents of the Shakya clan, but renounced his home life to live as a wandering ascetic (). After leading a life of mendicancy, asceticism, and meditation, he attained enlightenment at Bodh Gaya in what is now India. The Buddha thereafter wandered through the lower Indo-Gangetic Plain, teaching and building a monastic order. He taught a Middle Way between sensual indulgence and severe asceticism, leading to Nirvana, that is, freedom from ignorance, craving, rebirth, and suffering. His teachings are summarized in the Noble Eightfold Path, a training of the mind that includes ethical training and meditative practices such as sense restraint, kindness toward others, mindfulness, and (meditation proper). He died in Kushinagar, attaining parinirvana. The Buddha has since been venerated by numerous religions and communities across Asia. A couple of centuries after his death, he came to be known by the title Buddha, which means 'Awakened One' or 'Enlightened One'. His teachings were compiled by the Buddhist community in the Vinaya, his codes for monastic practice, and the Sutta Piṭaka, a compilation of teachings based on his discourses. These were passed down in Middle Indo-Aryan dialects through an oral tradition. Later generations composed additional texts, such as systematic treatises known as Abhidharma, biographies of the Buddha, collections of stories about his past lives known as Jataka tales, and additional discourses, i.e., the Mahayana sutras. Etymology, names and titles Siddhārtha Gautama and Buddha Shakyamuni According to Donald Lopez Jr., "... he tended to be known as either Buddha or Sakyamuni in China, Korea, Japan, and Tibet, and as either Gotama Buddha or Samana Gotama ('the ascetic Gotama') in Sri Lanka and Southeast Asia." Buddha, "Awakened One" or "Enlightened One", is the masculine form of budh (बुध् ), "to wake, be awake, observe, heed, attend, learn, become aware of, to know, be conscious again", "to awaken" to open up' (as does a flower)", "one who has awakened from the deep sleep of ignorance and opened his consciousness to encompass all objects of knowledge". It is not a personal name, but a title for those who have attained bodhi (awakening, enlightenment). Buddhi, the power to "form and retain concepts, reason, discern, judge, comprehend, understand", is the faculty which discerns truth (satya) from falsehood. The name of his clan was Gautama (Pali: Gotama). His given name, "Siddhārtha" (Sanskrit; P. Siddhattha; T. Don grub; C. Xidaduo; J. Shiddatta/Shittatta; K. Siltalta) means "He Who Achieves His Goal". The clan name of Gautama means "descendant of Gotama", "Gotama" meaning "one who has the most light", and comes from the fact that Kshatriya clans adopted the names of their house priests. While the term "Buddha" is used in the Agamas and the Pali Canon, the oldest surviving written records of the term "Buddha" is from the middle of the 3rd century BCE, when several Edicts of Ashoka (reigned c. 269–232 BCE) mention the Buddha and Buddhism. Ashoka's Lumbini pillar inscription commemorates the Emperor's pilgrimage to Lumbini as the Buddha's birthplace, calling him the Buddha Shakyamuni (Brahmi script: 𑀩𑀼𑀥 𑀲𑀓𑁆𑀬𑀫𑀼𑀦𑀻 Bu-dha Sa-kya-mu-nī, "Buddha, Sage of the Shakyas"). Shakyamuni () means "Sage of the Shakyas". Tathāgata Tathāgata (Pali; ) is a term the Buddha commonly used when referring to himself or other Buddhas in the Pāli Canon. The exact meaning of the term is unknown, but it is often thought to mean either "one who has thus gone" (tathā-gata), "one who has thus come" (tathā-āgata), or sometimes "one who has thus not gone" (tathā-agata). This is interpreted as signifying that the Tathāgata is beyond all coming and going – beyond all transitory phenomena. A tathāgata is "immeasurable", "inscrutable", "hard to fathom", and "not apprehended". Other epithets A list of other epithets is commonly seen together in canonical texts and depicts some of his perfected qualities: Bhagavato (Bhagavan) – The Blessed one, one of the most used epithets, together with tathāgata Sammasambuddho – Perfectly self-awakened Vijja-carana-sampano – Endowed with higher knowledge and ideal conduct. Sugata – Well-gone or Well-spoken. Lokavidu – Knower of the many worlds. Anuttaro Purisa-damma-sarathi – Unexcelled trainer of untrained people. Satthadeva-Manussanam – Teacher of gods and humans. Araham – Worthy of homage. An Arahant is "one with taints destroyed, who has lived the holy life, done what had to be done, laid down the burden, reached the true goal, destroyed the fetters of being, and is completely liberated through final knowledge". Jina – Conqueror. Although the term is more commonly used to name an individual who has attained liberation in the religion Jainism, it is also an alternative title for the Buddha. The Pali Canon also contains numerous other titles and epithets for the Buddha, including: All-seeing, All-transcending sage, Bull among men, The Caravan leader, Dispeller of darkness, The Eye, Foremost of charioteers, Foremost of those who can cross, King of the Dharma (Dharmaraja), Kinsman of the Sun, Helper of the World (Lokanatha), Lion (Siha), Lord of the Dhamma, Of excellent wisdom (Varapañña), Radiant One, Torchbearer of mankind, Unsurpassed doctor and surgeon, Victor in battle, and Wielder of power. Another epithet, used at inscriptions throughout South and Southeast Asia, is Maha sramana, "great sramana" (ascetic, renunciate). Sources Historical sources Pali suttas On the basis of philological evidence, Indologist and Pāli expert Oskar von Hinüber says that some of the Pāli suttas have retained very archaic place-names, syntax, and historical data from close to the Buddha's lifetime, including the Mahāparinibbāṇa Sutta which contains a detailed account of the Buddha's final days. Hinüber proposes a composition date of no later than 350–320 BCE for this text, which would allow for a "true historical memory" of the events approximately 60 years prior if the Short Chronology for the Buddha's lifetime is accepted (but he also points out that such a text was originally intended more as hagiography than as an exact historical record of events). John S. Strong sees certain biographical fragments in the canonical texts preserved in Pāli, as well as Chinese, Tibetan and Sanskrit as the earliest material. These include texts such as the "Discourse on the Noble Quest" (Ariyapariyesanā-sutta) and its parallels in other languages. Pillar and rock inscriptions No written records about Gautama were found from his lifetime or from the one or two centuries thereafter. But from the middle of the 3rd century BCE, several Edicts of Ashoka (reigned c. 268 to 232 BCE) mention the Buddha and Buddhism. Particularly, Ashoka's Lumbini pillar inscription commemorates the Emperor's pilgrimage to Lumbini as the Buddha's birthplace, calling him the Buddha Shakyamuni (Brahmi script: 𑀩𑀼𑀥 𑀲𑀓𑁆𑀬𑀫𑀼𑀦𑀻 Bu-dha Sa-kya-mu-nī, "Buddha, Sage of the Shakyas"). Another one of his edicts (Minor Rock Edict No. 3) mentions the titles of several Dhamma texts (in Buddhism, "dhamma" is another word for "dharma"), establishing the existence of a written Buddhist tradition at least by the time of the Maurya era. These texts may be the precursor of the Pāli Canon. "Sakamuni" is also mentioned in a relief of Bharhut, dated to c. 100 BCE, in relation with his illumination and the Bodhi tree, with the inscription Bhagavato Sakamunino Bodho ("The illumination of the Blessed Sakamuni"). Oldest surviving manuscripts The oldest surviving Buddhist manuscripts are the Gandhāran Buddhist texts, found in Gandhara (corresponding to modern northwestern Pakistan and eastern Afghanistan) and written in Gāndhārī, they date from the first century BCE to the third century CE. Biographical sources Early canonical sources include the Ariyapariyesana Sutta (MN 26), the Mahāparinibbāṇa Sutta (DN 16), the Mahāsaccaka-sutta (MN 36), the Mahapadana Sutta (DN 14), and the Achariyabhuta Sutta (MN 123), which include selective accounts that may be older, but are not full biographies. The Jātaka tales retell previous lives of Gautama as a bodhisattva, and the first collection of these can be dated among the earliest Buddhist texts. The Mahāpadāna Sutta and Achariyabhuta Sutta both recount miraculous events surrounding Gautama's birth, such as the bodhisattva's descent from the Tuṣita Heaven into his mother's womb. The sources which present a complete picture of the life of Siddhārtha Gautama are a variety of different, and sometimes conflicting, traditional biographies from a later date. These include the Buddhacarita, Lalitavistara Sūtra, Mahāvastu, and the Nidānakathā. Of these, the Buddhacarita is the earliest full biography, an epic poem written by the poet Aśvaghoṣa in the first century CE. The Lalitavistara Sūtra is the next oldest biography, a Mahāyāna/Sarvāstivāda biography dating to the 3rd century CE. The Mahāvastu from the Mahāsāṃghika Lokottaravāda tradition is another major biography, composed incrementally until perhaps the 4th century CE. The Dharmaguptaka biography of the Buddha is the most exhaustive, and is entitled the Abhiniṣkramaṇa Sūtra, and various Chinese translations of this date between the 3rd and 6th century CE. The Nidānakathā is from the Theravada tradition in Sri Lanka and was composed in the 5th century by Buddhaghoṣa. Historical person Understanding the historical person Scholars are hesitant to make claims about the historical facts of the Buddha's life. Most of them accept that the Buddha lived, taught, and founded a monastic order during the Mahajanapada, and during the reign of Bimbisara (his friend, protector, and ruler of the Magadha empire); and died during the early years of the reign of Ajatashatru (who was the successor of Bimbisara) thus making him a younger contemporary of Mahavira, the Jain tirthankara. There is less consensus on the veracity of many details contained in traditional biographies, as "Buddhist scholars [...] have mostly given up trying to understand the historical person." The earliest versions of Buddhist biographical texts that we have already contain many supernatural, mythical or legendary elements. In the 19th century some scholars simply omitted these from their accounts of the life, so that "the image projected was of a Buddha who was a rational, socratic teacher—a great person perhaps, but a more or less ordinary human being". More recent scholars tend to see such demythologisers as remythologisers, "creating a Buddha that appealed to them, by eliding one that did not". Dating The dates of Gautama's birth and death are uncertain. Within the Eastern Buddhist tradition of China, Vietnam, Korea and Japan, the traditional date for Buddha's death was 949 BCE, but according to the Ka-tan system of the Kalachakra tradition, Buddha's death was about 833 BCE. Buddhist texts present two chronologies which have been used to date the lifetime of the Buddha. The "long chronology", from Sri Lankese chronicles, states the Buddha was born 298 years before Asoka's coronation and died 218 years before the coronation, thus a lifespan of about 80 years. According to these chronicles, Asoka was crowned in 326 BCE, which gives Buddha's lifespan as 624 – 544 BCE, and are the accepted dates in Sri Lanka and South-East Asia. Alternatively, most scholars who also accept the long chronology but date Asoka's coronation around 268 BCE (based on Greek evidence) put the Buddha's lifespan later at 566 – 486 BCE. However, the "short chronology", from Indian sources and their Chinese and Tibetan translations, place the Buddha's birth at 180 years before Asoka's coronation and death 100 years before the coronation, still about 80 years. Following the Greek sources of Asoka's coronation as 268 BCE, this dates the Buddha's lifespan even later as 448 – 368 BCE. Most historians in the early 20th century use the earlier dates of 563 – 483 BCE, differing from the long chronology based on Greek evidence by just three years. More recently, there are attempts to put his death midway between the long chronology's 480s BCE and the short chronology's 360s BCE, so circa 410 BCE. At a symposium on this question held in 1988, the majority of those who presented gave dates within 20 years either side of 400 BCE for the Buddha's death. These alternative chronologies, however, have not been accepted by all historians. The dating of Bimbisara and Ajatashatru also depends on the long or short chronology. In the long chrononology, Bimbisara reigned , and died 492 BCE, while Ajatashatru reigned . In the short chronology Bimbisara reigned c. 400 BCE, while Ajatashatru died between c. 380 BCE and 330 BCE.) Historical context Shakyas According to the Buddhist tradition, Shakyamuni Buddha was a Shakya, a sub-Himalayan ethnicity and clan of north-eastern region of the Indian subcontinent. The Shakya community was on the periphery, both geographically and culturally, of the eastern Indian subcontinent in the 5th century BCE. The community, though describable as a small republic, was probably an oligarchy, with his father as the elected chieftain or oligarch. The Shakyas were widely considered to be non-Vedic (and, hence impure) in Brahminic texts; their origins remain speculative and debated. Bronkhorst terms this culture, which grew alongside Aryavarta without being affected by the flourish of Brahminism, as Greater Magadha. The Buddha's tribe of origin, the Shakyas, seems to have had non-Vedic religious practices which persist in Buddhism, such as the veneration of trees and sacred groves, and the worship of tree spirits (yakkhas) and serpent beings (nagas). They also seem to have built burial mounds called stupas. Tree veneration remains important in Buddhism today, particularly in the practice of venerating Bodhi trees. Likewise, yakkas and nagas have remained important figures in Buddhist religious practices and mythology. Shramanas The Buddha's lifetime coincided with the flourishing of influential śramaṇa schools of thought like Ājīvika, Cārvāka, Jainism, and Ajñana. The Brahmajala Sutta records sixty-two such schools of thought. In this context, a śramaṇa refers to one who labours, toils or exerts themselves (for some higher or religious purpose). It was also the age of influential thinkers like Mahavira, Pūraṇa Kassapa, Makkhali Gosāla, Ajita Kesakambalī, Pakudha Kaccāyana, and Sañjaya Belaṭṭhaputta, as recorded in Samaññaphala Sutta, with whose viewpoints the Buddha must have been acquainted. Śāriputra and Moggallāna, two of the foremost disciples of the Buddha, were formerly the foremost disciples of Sañjaya Belaṭṭhaputta, the sceptic. The Pāli canon frequently depicts Buddha engaging in debate with the adherents of rival schools of thought. There is philological evidence to suggest that the two masters, Alara Kalama and Uddaka Rāmaputta, were historical figures and they most probably taught Buddha two different forms of meditative techniques. Thus, Buddha was just one of the many śramaṇa philosophers of that time. In an era where holiness of person was judged by their level of asceticism, Buddha was a reformist within the śramaṇa movement, rather than a reactionary against Vedic Brahminism. Coningham and Young note that both Jains and Buddhists used stupas, while tree shrines can be found in both Buddhism and Hinduism. Urban environment and egalitarianism The rise of Buddhism coincided with the Second Urbanisation, in which the Ganges Basin was settled and cities grew, in which egalitarianism prevailed. According to Thapar, the Buddha's teachings were "also a response to the historical changes of the time, among which were the emergence of the state and the growth of urban centres". While the Buddhist mendicants renounced society, they lived close to the villages and cities, depending for alms-givings on lay supporters. According to Dyson, the Ganges basin was settled from the north-west and the south-east, as well as from within, "[coming] together in what is now Bihar (the location of Pataliputra)". The Ganges basin was densely forested, and the population grew when new areas were deforestated and cultivated. The society of the middle Ganges basin lay on "the outer fringe of Aryan cultural influence", and differed significantly from the Aryan society of the western Ganges basin. According to Stein and Burton, "[t]he gods of the brahmanical sacrificial cult were not rejected so much as ignored by Buddhists and their contemporaries." Jainism and Buddhism opposed the social stratification of Brahmanism, and their egalitarism prevailed in the cities of the middle Ganges basin. This "allowed Jains and Buddhists to engage in trade more easily than Brahmans, who were forced to follow strict caste prohibitions." Semi-legendary biography Nature of traditional depictions In the earliest Buddhist texts, the nikāyas and āgamas, the Buddha is not depicted as possessing omniscience (sabbaññu) nor is he depicted as being an eternal transcendent (lokottara) being. According to Bhikkhu Analayo, ideas of the Buddha's omniscience (along with an increasing tendency to deify him and his biography) are found only later, in the Mahayana sutras and later Pali commentaries or texts such as the Mahāvastu. In the Sandaka Sutta, the Buddha's disciple Ananda outlines an argument against the claims of teachers who say they are all knowing while in the Tevijjavacchagotta Sutta the Buddha himself states that he has never made a claim to being omniscient, instead he claimed to have the "higher knowledges" (abhijñā). The earliest biographical material from the Pali Nikayas focuses on the Buddha's life as a śramaṇa, his search for enlightenment under various teachers such as Alara Kalama and his forty-five-year career as a teacher. Traditional biographies of Gautama often include numerous miracles, omens, and supernatural events. The character of the Buddha in these traditional biographies is often that of a fully transcendent (Skt. lokottara) and perfected being who is unencumbered by the mundane world. In the Mahāvastu, over the course of many lives, Gautama is said to have developed supramundane abilities including: a painless birth conceived without intercourse; no need for sleep, food, medicine, or bathing, although engaging in such "in conformity with the world"; omniscience, and the ability to "suppress karma". As noted by Andrew Skilton, the Buddha was often described as being superhuman, including descriptions of him having the 32 major and 80 minor marks of a "great man", and the idea that the Buddha could live for as long as an aeon if he wished (see DN 16). The ancient Indians were generally unconcerned with chronologies, being more focused on philosophy. Buddhist texts reflect this tendency, providing a clearer picture of what Gautama may have taught than of the dates of the events in his life. These texts contain descriptions of the culture and daily life of ancient India which can be corroborated from the Jain scriptures, and make the Buddha's time the earliest period in Indian history for which significant accounts exist. British author Karen Armstrong writes that although there is very little information that can be considered historically sound, we can be reasonably confident that Siddhārtha Gautama did exist as a historical figure. Michael Carrithers goes further, stating that the most general outline of "birth, maturity, renunciation, search, awakening and liberation, teaching, death" must be true. Previous lives Legendary biographies like the Pali Buddhavaṃsa and the Sanskrit Jātakamālā depict the Buddha's (referred to as "bodhisattva" before his awakening) career as spanning hundreds of lifetimes before his last birth as Gautama. Many of these previous lives are narrated in the Jatakas, which consists of 547 stories. The format of a Jataka typically begins by telling a story in the present which is then explained by a story of someone's previous life. Besides imbuing the pre-Buddhist past with a deep karmic history, the Jatakas also serve to explain the bodhisattva's (the Buddha-to-be) path to Buddhahood. In biographies like the Buddhavaṃsa, this path is described as long and arduous, taking "four incalculable ages" (asamkheyyas). In these legendary biographies, the bodhisattva goes through many different births (animal and human), is inspired by his meeting of past Buddhas, and then makes a series of resolves or vows (pranidhana) to become a Buddha himself. Then he begins to receive predictions by past Buddhas. One of the most popular of these stories is his meeting with Dipankara Buddha, who gives the bodhisattva a prediction of future Buddhahood. Another theme found in the Pali Jataka Commentary (Jātakaṭṭhakathā) and the Sanskrit Jātakamālā is how the Buddha-to-be had to practice several "perfections" (pāramitā) to reach Buddhahood. The Jatakas also sometimes depict negative actions done in previous lives by the bodhisattva, which explain difficulties he experienced in his final life as Gautama. Birth and early life According to the Buddhist tradition, Gautama was born in Lumbini, now in modern-day Nepal, and raised in Kapilavastu. The exact site of ancient Kapilavastu is unknown. It may have been either Piprahwa, Uttar Pradesh, in present-day India, or Tilaurakot, in present-day Nepal. Both places belonged to the Sakya territory, and are located only apart. In the mid-3rd century BCE the Emperor Ashoka determined that Lumbini was Gautama's birthplace and thus installed a pillar there with the inscription: "...this is where the Buddha, sage of the Śākyas (Śākyamuni), was born." According to later biographies such as the Mahavastu and the Lalitavistara, his mother, Maya (Māyādevī), Suddhodana's wife, was a princess from Devdaha, the ancient capital of the Koliya Kingdom (what is now the Rupandehi District of Nepal). Legend has it that, on the night Siddhartha was conceived, Queen Maya dreamt that a white elephant with six white tusks entered her right side, and ten months later Siddhartha was born. As was the Shakya tradition, when his mother Queen Maya became pregnant, she left Kapilavastu for her father's kingdom to give birth. Her son is said to have been born on the way, at Lumbini, in a garden beneath a sal tree. The earliest Buddhist sources state that the Buddha was born to an aristocratic Kshatriya (Pali: khattiya) family called Gotama (Sanskrit: Gautama), who were part of the Shakyas, a tribe of rice-farmers living near the modern border of India and Nepal. His father Śuddhodana was "an elected chief of the Shakya clan", whose capital was Kapilavastu, and who were later annexed by the growing Kingdom of Kosala during the Buddha's lifetime. The early Buddhist texts contain very little information about the birth and youth of Gotama Buddha. Later biographies developed a dramatic narrative about the life of the young Gotama as a prince and his existential troubles. They depict his father Śuddhodana as a hereditary monarch of the Suryavansha (Solar dynasty) of (Pāli: Okkāka). This is unlikely, as many scholars think that Śuddhodana was merely a Shakya aristocrat (khattiya), and that the Shakya republic was not a hereditary monarchy. The more egalitarian form of government, as a political alternative to Indian monarchies, may have influenced the development of the śramanic Jain and Buddhist sanghas, where monarchies tended toward Vedic Brahmanism. The day of the Buddha's birth, enlightenment and death is widely celebrated in Theravada countries as Vesak and the day he got conceived as Poson. Buddha's Birthday is called Buddha Purnima in Nepal, Bangladesh, and India as he is believed to have been born on a full moon day. According to later biographical legends, during the birth celebrations, the hermit seer Asita journeyed from his mountain abode, analyzed the child for the "32 marks of a great man" and then announced that he would either become a great king (chakravartin) or a great religious leader. Suddhodana held a naming ceremony on the fifth day and invited eight Brahmin scholars to read the future. All gave similar predictions. Kondañña, the youngest, and later to be the first arhat other than the Buddha, was reputed to be the only one who unequivocally predicted that Siddhartha would become a Buddha. Early texts suggest that Gautama was not familiar with the dominant religious teachings of his time until he left on his religious quest, which is said to have been motivated by existential concern for the human condition. According to the early Buddhist Texts of several schools, and numerous post-canonical accounts, Gotama had a wife, Yasodhara, and a son, named Rāhula. Besides this, the Buddha in the early texts reports that "I lived a spoilt, a very spoilt life, monks (in my parents' home)." The legendary biographies like the Lalitavistara also tell stories of young Gotama's great martial skill, which was put to the test in various contests against other Shakyan youths. Renunciation While the earliest sources merely depict Gotama seeking a higher spiritual goal and becoming an ascetic or śramaṇa after being disillusioned with lay life, the later legendary biographies tell a more elaborate dramatic story about how he became a mendicant. The earliest accounts of the Buddha's spiritual quest is found in texts such as the Pali Ariyapariyesanā-sutta ("The discourse on the noble quest", MN 26) and its Chinese parallel at MĀ 204. These texts report that what led to Gautama's renunciation was the thought that his life was subject to old age, disease and death and that there might be something better (i.e. liberation, nirvana). The early texts also depict the Buddha's explanation for becoming a sramana as follows: "The household life, this place of impurity, is narrow – the samana life is the free open air. It is not easy for a householder to lead the perfected, utterly pure and perfect holy life." MN 26, MĀ 204, the Dharmaguptaka Vinaya and the Mahāvastu all agree that his mother and father opposed his decision and "wept with tearful faces" when he decided to leave. Legendary biographies also tell the story of how Gautama left his palace to see the outside world for the first time and how he was shocked by his encounter with human suffering. These depict Gautama's father as shielding him from religious teachings and from knowledge of human suffering, so that he would become a great king instead of a great religious leader. In the Nidanakatha (5th century CE), Gautama is said to have seen an old man. When his charioteer Chandaka explained to him that all people grew old, the prince went on further trips beyond the palace. On these he encountered a diseased man, a decaying corpse, and an ascetic that inspired him. This story of the "four sights" seems to be adapted from an earlier account in the Digha Nikaya (DN 14.2) which instead depicts the young life of a previous Buddha, Vipassi. The legendary biographies depict Gautama's departure from his palace as follows. Shortly after seeing the four sights, Gautama woke up at night and saw his female servants lying in unattractive, corpse-like poses, which shocked him. Therefore, he discovered what he would later understand more deeply during his enlightenment: dukkha ("standing unstable", "dissatisfaction") and the end of dukkha. Moved by all the things he had experienced, he decided to leave the palace in the middle of the night against the will of his father, to live the life of a wandering ascetic. Accompanied by Chandaka and riding his horse Kanthaka, Gautama leaves the palace, leaving behind his son Rahula and Yaśodhara. He travelled to the river Anomiya, and cut off his hair. Leaving his servant and horse behind, he journeyed into the woods and changed into monk's robes there, though in some other versions of the story, he received the robes from a Brahma deity at Anomiya. According to the legendary biographies, when the ascetic Gautama first went to Rajagaha (present-day Rajgir) to beg for alms in the streets, King Bimbisara of Magadha learned of his quest, and offered him a share of his kingdom. Gautama rejected the offer but promised to visit his kingdom first, upon attaining enlightenment. Ascetic life and awakening Majjhima Nikaya 4 mentions that Gautama lived in "remote jungle thickets" during his years of spiritual striving and had to overcome the fear that he felt while living in the forests. The Nikaya-texts narrate that the ascetic Gautama practised under two teachers of yogic meditation. According to the Ariyapariyesanā-sutta (MN 26) and its Chinese parallel at MĀ 204, after having mastered the teaching of Ārāḍa Kālāma (), who taught a meditation attainment called "the sphere of nothingness", he was asked by Ārāḍa to become an equal leader of their spiritual community. Gautama felt unsatisfied by the practice because it "does not lead to revulsion, to dispassion, to cessation, to calm, to knowledge, to awakening, to Nibbana", and moved on to become a student of Udraka Rāmaputra (). With him, he achieved high levels of meditative consciousness (called "The Sphere of Neither Perception nor Non-Perception") and was again asked to join his teacher. But, once more, he was not satisfied for the same reasons as before, and moved on. According to some sutras, after leaving his meditation teachers, Gotama then practiced ascetic techniques. The ascetic techniques described in the early texts include very minimal food intake, different forms of breath control, and forceful mind control. The texts report that he became so emaciated that his bones became visible through his skin. The Mahāsaccaka-sutta and most of its parallels agree that after taking asceticism to its extremes, Gautama realized that this had not helped him attain nirvana, and that he needed to regain strength to pursue his goal. One popular story tells of how he accepted milk and rice pudding from a village girl named Sujata. His break with asceticism is said to have led his five companions to abandon him, since they believed that he had abandoned his search and become undisciplined. At this point, Gautama remembered a previous experience of dhyana ("meditation") he had as a child sitting under a tree while his father worked. This memory leads him to understand that dhyana is the path to liberation, and the texts then depict the Buddha achieving all four dhyanas, followed by the "three higher knowledges" (tevijja), culminating in complete insight into the Four Noble Truths, thereby attaining liberation from samsara, the endless cycle of rebirth. According to the Dhammacakkappavattana Sutta (SN 56), the Tathagata, the term Gautama uses most often to refer to himself, realized "the Middle Way"—a path of moderation away from the extremes of self-indulgence and self-mortification, or the Noble Eightfold Path. In later centuries, Gautama became known as the Buddha or "Awakened One". The title indicates that unlike most people who are "asleep", a Buddha is understood as having "woken up" to the true nature of reality and sees the world 'as it is' (yatha-bhutam). A Buddha has achieved liberation (vimutti), also called Nirvana, which is seen as the extinguishing of the "fires" of desire, hatred, and ignorance, that keep the cycle of suffering and rebirth going. Following his decision to leave his meditation teachers, MĀ 204 and other parallel early texts report that Gautama sat down with the determination not to get up until full awakening (sammā-sambodhi) had been reached; the Ariyapariyesanā-sutta does not mention "full awakening", but only that he attained nirvana. This event was said to have occurred under a pipal tree—known as "the Bodhi tree"—in Bodh Gaya, Bihar. As reported by various texts from the Pali Canon, the Buddha sat for seven days under the bodhi tree "feeling the bliss of deliverance". The Pali texts also report that he continued to meditate and contemplated various aspects of the Dharma while living by the River Nairañjanā, such as Dependent Origination, the Five Spiritual Faculties and suffering (dukkha). The legendary biographies like the Mahavastu, Nidanakatha and the Lalitavistara depict an attempt by Mara, the ruler of the desire realm, to prevent the Buddha's nirvana. He does so by sending his daughters to seduce the Buddha, by asserting his superiority and by assaulting him with armies of monsters. However the Buddha is unfazed and calls on the earth (or in some versions of the legend, the earth goddess) as witness to his superiority by touching the ground before entering meditation. Other miracles and magical events are also depicted. First sermon and formation of the saṅgha According to MN 26, immediately after his awakening, the Buddha hesitated on whether or not he should teach the Dharma to others. He was concerned that humans were overpowered by ignorance, greed, and hatred that it would be difficult for them to recognise the path, which is "subtle, deep and hard to grasp". However, the god Brahmā Sahampati convinced him, arguing that at least some "with little dust in their eyes" will understand it. The Buddha relented and agreed to teach. According to Anālayo, the Chinese parallel to MN 26, MĀ 204, does not contain this story, but this event does appear in other parallel texts, such as in an Ekottarika-āgama discourse, in the Catusparisat-sūtra, and in the Lalitavistara. According to MN 26 and MĀ 204, after deciding to teach, the Buddha initially intended to visit his former teachers, Alara Kalama and Udaka Ramaputta, to teach them his insights, but they had already died, so he decided to visit his five former companions. MN 26 and MĀ 204 both report that on his way to Vārānasī (Benares), he met another wanderer, an Ājīvika ascetic named Upaka in MN 26. The Buddha proclaimed that he had achieved full awakening, but Upaka was not convinced and "took a different path". MN 26 and MĀ 204 continue with the Buddha reaching the Deer Park (Sarnath) (Mrigadāva, also called Rishipatana, "site where the ashes of the ascetics fell") near Vārānasī, where he met the group of five ascetics and was able to convince them that he had indeed reached full awakening. According to MĀ 204 (but not MN 26), as well as the Theravāda Vinaya, an Ekottarika-āgama text, the Dharmaguptaka Vinaya, the Mahīśāsaka Vinaya, and the Mahāvastu, the Buddha then taught them the "first sermon", also known as the "Benares sermon", i.e. the teaching of "the noble eightfold path as the middle path aloof from the two extremes of sensual indulgence and self-mortification". The Pali text reports that after the first sermon, the ascetic Koṇḍañña (Kaundinya) became the first arahant (liberated being) and the first Buddhist bhikkhu or monastic. The Buddha then continued to teach the other ascetics and they formed the first , the company of Buddhist monks. Various sources such as the Mahāvastu, the Mahākhandhaka of the Theravāda Vinaya and the Catusparisat-sūtra also mention that the Buddha taught them his second discourse, about the characteristic of "not-self" (Anātmalakṣaṇa Sūtra), at this time or five days later. After hearing this second sermon the four remaining ascetics also reached the status of arahant. The Theravāda Vinaya and the Catusparisat-sūtra also speak of the conversion of Yasa, a local guild master, and his friends and family, who were some of the first laypersons to be converted and to enter the Buddhist community. The conversion of three brothers named Kassapa followed, who brought with them five hundred converts who had previously been "matted hair ascetics", and whose spiritual practice was related to fire sacrifices. According to the Theravāda Vinaya, the Buddha then stopped at the Gayasisa hill near Gaya and delivered his third discourse, the Ādittapariyāya Sutta (The Discourse on Fire), in which he taught that everything in the world is inflamed by passions and only those who follow the Eightfold path can be liberated. At the end of the rainy season, when the Buddha's community had grown to around sixty awakened monks, he instructed them to wander on their own, teach and ordain people into the community, for the "welfare and benefit" of the world. Travels and growth of the saṅgha For the remaining 40 or 45 years of his life, the Buddha is said to have travelled in the Gangetic Plain, in what is now Uttar Pradesh, Bihar, and southern Nepal, teaching a diverse range of people: from nobles to servants, ascetics and householders, murderers such as Angulimala, and cannibals such as Alavaka. According to Schumann, the Buddha's travels ranged from "Kosambi on the Yamuna (25 km south-west of Allahabad )", to Campa (40 km east of Bhagalpur)" and from "Kapilavatthu (95 km north-west of Gorakhpur) to Uruvela (south of Gaya)". This covers an area of 600 by 300 km. His sangha enjoyed the patronage of the kings of Kosala and Magadha and he thus spent a lot of time in their respective capitals, Savatthi and Rajagaha. Although the Buddha's language remains unknown, it is likely that he taught in one or more of a variety of closely related Middle Indo-Aryan dialects, of which Pali may be a standardisation. The sangha wandered throughout the year, except during the four months of the Vassa rainy season when ascetics of all religions rarely travelled. One reason was that it was more difficult to do so without causing harm to flora and animal life. The health of the ascetics might have been a concern as well. At this time of year, the sangha would retreat to monasteries, public parks or forests, where people would come to them. The first vassana was spent at Varanasi when the sangha was formed. According to the Pali texts, shortly after the formation of the sangha, the Buddha travelled to Rajagaha, capital of Magadha, and met with King Bimbisara, who gifted a bamboo grove park to the sangha. The Buddha's sangha continued to grow during his initial travels in north India. The early texts tell the story of how the Buddha's chief disciples, Sāriputta and Mahāmoggallāna, who were both students of the skeptic sramana Sañjaya Belaṭṭhiputta, were converted by Assaji. They also tell of how the Buddha's son, Rahula, joined his father as a bhikkhu when the Buddha visited his old home, Kapilavastu. Over time, other Shakyans joined the order as bhikkhus, such as Buddha's cousin Ananda, Anuruddha, Upali the barber, the Buddha's half-brother Nanda and Devadatta. Meanwhile, the Buddha's father Suddhodana heard his son's teaching, converted to Buddhism and became a stream-enterer. The early texts also mention an important lay disciple, the merchant Anāthapiṇḍika, who became a strong lay supporter of the Buddha early on. He is said to have gifted Jeta's grove (Jetavana) to the sangha at great expense (the Theravada Vinaya speaks of thousands of gold coins). Formation of the bhikkhunī order The formation of a parallel order of female monastics (bhikkhunī) was another important part of the growth of the Buddha's community. As noted by Anālayo's comparative study of this topic, there are various versions of this event depicted in the different early Buddhist texts. According to all the major versions surveyed by Anālayo, Mahāprajāpatī Gautamī, Buddha's step-mother, is initially turned down by the Buddha after requesting ordination for her and some other women. Mahāprajāpatī and her followers then shave their hair, don robes and begin following the Buddha on his travels. The Buddha is eventually convinced by Ānanda to grant ordination to Mahāprajāpatī on her acceptance of eight conditions called gurudharmas which focus on the relationship between the new order of nuns and the monks. According to Anālayo, the only argument common to all the versions that Ananda uses to convince the Buddha is that women have the same ability to reach all stages of awakening. Anālayo also notes that some modern scholars have questioned the authenticity of the eight gurudharmas in their present form due to various inconsistencies. He holds that the historicity of the current lists of eight is doubtful, but that they may have been based on earlier injunctions by the Buddha. Anālayo notes that various passages indicate that the reason for the Buddha's hesitation to ordain women was the danger that the life of a wandering sramana posed for women that were not under the protection of their male family members, such as dangers of sexual assault and abduction. Due to this, the gurudharma injunctions may have been a way to place "the newly founded order of nuns in a relationship to its male counterparts that resembles as much as possible the protection a laywoman could expect from her male relatives". Later years According to J.S. Strong, after the first 20 years of his teaching career, the Buddha seems to have slowly settled in Sravasti, the capital of the Kingdom of Kosala, spending most of his later years in this city. As the sangha grew in size, the need for a standardized set of monastic rules arose and the Buddha seems to have developed a set of regulations for the sangha. These are preserved in various texts called "Pratimoksa" which were recited by the community every fortnight. The Pratimoksa includes general ethical precepts, as well as rules regarding the essentials of monastic life, such as bowls and robes. In his later years, the Buddha's fame grew and he was invited to important royal events, such as the inauguration of the new council hall of the Shakyans (as seen in MN 53) and the inauguration of a new palace by Prince Bodhi (as depicted in MN 85). The early texts also speak of how during the Buddha's old age, the kingdom of Magadha was usurped by a new king, Ajatashatru, who overthrew his father Bimbisara. According to the Samaññaphala Sutta, the new king spoke with different ascetic teachers and eventually took refuge in the Buddha. However, Jain sources also claim his allegiance, and it is likely he supported various religious groups, not just the Buddha's sangha exclusively. As the Buddha continued to travel and teach, he also came into contact with members of other śrāmana sects. There is evidence from the early texts that the Buddha encountered some of these figures and critiqued their doctrines. The Samaññaphala Sutta identifies six such sects. The early texts also depict the elderly Buddha as suffering from back pain. Several texts depict him delegating teachings to his chief disciples since his body now needed more rest. However, the Buddha continued teaching well into his old age. One of the most troubling events during the Buddha's old age was Devadatta's schism. Early sources speak of how the Buddha's cousin, Devadatta, attempted to take over leadership of the order and then left the sangha with several Buddhist monks and formed a rival sect. This sect is said to have been supported by King Ajatashatru. The Pali texts depict Devadatta as plotting to kill the Buddha, but these plans all fail. They depict the Buddha as sending his two chief disciples (Sariputta and Moggallana) to this schismatic community in order to convince the monks who left with Devadatta to return. All the major early Buddhist Vinaya texts depict Devadatta as a divisive figure who attempted to split the Buddhist community, but they disagree on what issues he disagreed with the Buddha on. The Sthavira texts generally focus on "five points" which are seen as excessive ascetic practices, while the Mahāsaṅghika Vinaya speaks of a more comprehensive disagreement, which has Devadatta alter the discourses as well as monastic discipline. At around the same time of Devadatta's schism, there was also war between Ajatashatru's Kingdom of Magadha, and Kosala, led by an elderly king Pasenadi. Ajatashatru seems to have been victorious, a turn of events the Buddha is reported to have regretted. Last days and parinirvana The main narrative of the Buddha's last days, death and the events following his death is contained in the Mahaparinibbana Sutta (DN 16) and its various parallels in Sanskrit, Chinese, and Tibetan. According to Anālayo, these include the Chinese Dirgha Agama 2, "Sanskrit fragments of the Mahaparinirvanasutra", and "three discourses preserved as individual translations in Chinese". The Mahaparinibbana sutta depicts the Buddha's last year as a time of war. It begins with Ajatashatru's decision to make war on the Vajjika League, leading him to send a minister to ask the Buddha for advice. The Buddha responds by saying that the Vajjikas can be expected to prosper as long as they do seven things, and he then applies these seven principles to the Buddhist Sangha, showing that he is concerned about its future welfare. The Buddha says that the Sangha will prosper as long as they "hold regular and frequent assemblies, meet in harmony, do not change the rules of training, honour their superiors who were ordained before them, do not fall prey to worldly desires, remain devoted to forest hermitages, and preserve their personal mindfulness". He then gives further lists of important virtues to be upheld by the Sangha. The early texts depict how the Buddha's two chief disciples, Sariputta and Moggallana, died just before the Buddha's death. The Mahaparinibbana depicts the Buddha as experiencing illness during the last months of his life but initially recovering. It depicts him as stating that he cannot promote anyone to be his successor. When Ānanda requested this, the Mahaparinibbana records his response as follows: After travelling and teaching some more, the Buddha ate his last meal, which he had received as an offering from a blacksmith named Cunda. Falling violently ill, Buddha instructed his attendant Ānanda to convince Cunda that the meal eaten at his place had nothing to do with his death and that his meal would be a source of the greatest merit as it provided the last meal for a Buddha. Bhikkhu Mettanando and Oskar von Hinüber argue that the Buddha died of mesenteric infarction, a symptom of old age, rather than food poisoning. The precise contents of the Buddha's final meal are not clear, due to variant scriptural traditions and ambiguity over the translation of certain significant terms. The Theravada tradition generally believes that the Buddha was offered some kind of pork, while the Mahayana tradition believes that the Buddha consumed some sort of truffle or other mushroom. These may reflect the different traditional views on Buddhist vegetarianism and the precepts for monks and nuns. Modern scholars also disagree on this topic, arguing both for pig's flesh or some kind of plant or mushroom that pigs like to eat. Whatever the case, none of the sources which mention the last meal attribute the Buddha's sickness to the meal itself. As per the Mahaparinibbana sutta, after the meal with Cunda, the Buddha and his companions continued travelling until he was too weak to continue and had to stop at Kushinagar, where Ānanda had a resting place prepared in a grove of Sala trees. After announcing to the sangha at large that he would soon be passing away to final Nirvana, the Buddha ordained one last novice into the order personally. His name was Subhadda. He then repeated his final instructions to the sangha, which was that the Dhamma and Vinaya was to be their teacher after his death. Then he asked if anyone had any doubts about the teaching, but nobody did. The Buddha's final words are reported to have been: "All saṅkhāras decay. Strive for the goal with diligence (appamāda)" (Pali: 'vayadhammā saṅkhārā appamādena sampādethā'). He then entered his final meditation and died, reaching what is known as parinirvana (final nirvana, the end of rebirth and suffering achieved after the death of the body). The Mahaparinibbana reports that in his final meditation he entered the four dhyanas consecutively, then the four immaterial attainments and finally the meditative dwelling known as nirodha-samāpatti, before returning to the fourth dhyana right at the moment of death. Posthumous events According to the Mahaparinibbana sutta, the Mallians of Kushinagar spent the days following the Buddha's death honouring his body with flowers, music and scents. The sangha waited until the eminent elder Mahākassapa arrived to pay his respects before cremating the body. The Buddha's body was then cremated and the remains, including his bones, were kept as relics and they were distributed among various north Indian kingdoms like Magadha, Shakya and Koliya. These relics were placed in monuments or mounds called stupas, a common funerary practice at the time. Centuries later they would be exhumed and enshrined by Ashoka into many new stupas around the Mauryan realm. Many supernatural legends surround the history of alleged relics as they accompanied the spread of Buddhism and gave legitimacy to rulers. According to various Buddhist sources, the First Buddhist Council was held shortly after the Buddha's death to collect, recite and memorize the teachings. Mahākassapa was chosen by the sangha to be the chairman of the council. However, the historicity of the traditional accounts of the first council is disputed by modern scholars. Teachings and views Core teachings A number of teachings and practices are deemed essential to Buddhism, including: the samyojana (fetters, chains or bounds), that is, the sankharas ("formations"), the kleshas (uwholesome mental states), including the three poisons, and the āsavas ("influx, canker"), that perpetuate sasāra, the repeated cycle of becoming; the six sense bases and the five aggregates, which describe the process from sense contact to consciousness which lead to this bondage to sasāra; dependent origination, which describes this process, and its reversal, in detail; and the Middle Way, with the Four Noble Truths and the Noble Eightfold Path, which prescribes how this bondage can be reversed. According to N. Ross Reat, the Theravada Pali texts and the Mahasamghika school's Śālistamba Sūtra share these basic teachings and practices. Bhikkhu Analayo concludes that the Theravada Majjhima Nikaya and Sarvastivada Madhyama Agama contain mostly the same major doctrines. Likewise, Richard Salomon has written that the doctrines found in the Gandharan Manuscripts are "consistent with non-Mahayana Buddhism, which survives today in the Theravada school of Sri Lanka and Southeast Asia, but which in ancient times was represented by eighteen separate schools". Samsara All beings have deeply entrenched samyojana (fetters, chains or bounds), that is, the sankharas ("formations"), kleshas (unwholesome mental states), including the three poisons, and āsavas ("influx, canker"), that perpetuate sasāra, the repeated cycle of becoming and rebirth. According to the Pali suttas, the Buddha stated that "this saṃsāra is without discoverable beginning. A first point is not discerned of beings roaming and wandering on hindered by ignorance and fettered by craving." In the Dutiyalokadhammasutta sutta (AN 8:6) the Buddha explains how "eight worldly winds" "keep the world turning around [...] Gain and loss, fame and disrepute, praise and blame, pleasure and pain". He then explains how the difference between a noble (arya) person and an uninstructed worldling is that a noble person reflects on and understands the impermanence of these conditions. This cycle of becoming is characterized by dukkha, commonly referred to as "suffering", dukkha is more aptly rendered as "unsatisfactoriness" or "unease". It is the unsatisfactoriness and unease that comes with a life dictated by automatic responses and habituated selfishness, and the unsatifacories of expecting enduring happiness from things which are impermanent, unstable and thus unreliable. The ultimate noble goal should be liberation from this cycle. Samsara is dictated by karma, which is an impersonal natural law, similar to how certain seeds produce certain plants and fruits. Karma is not the only cause for one's conditions, as the Buddha listed various physical and environmental causes alongside karma. The Buddha's teaching of karma differed to that of the Jains and Brahmins, in that on his view, karma is primarily mental intention (as opposed to mainly physical action or ritual acts). The Buddha is reported to have said "By karma I mean intention." Richard Gombrich summarizes the Buddha's view of karma as follows: "all thoughts, words, and deeds derive their moral value, positive or negative, from the intention behind them." The six sense bases and the five aggregates The āyatana (six sense bases) and the five skandhas (aggregates) describe how sensory contact leads to attachment and dukkha. The six sense bases are eye and sight, ear and sound, nose and odour, tongue and taste, body and touch, and mind and thoughts. Together they create the input from which we create our world or reality, "the all". This process takes place through the five skandhas, "aggregates", "groups", "heaps", five groups of physical and mental processes, anmely form (or material image, impression) (), sensations (or feelings, received from form) (), perceptions (), mental activity or formations (), consciousness (). They form part of other Buddhist teachings and lists, such as dependent origination, and explain how sensory input ultimately leads to bondage to samsara by the mental defilements. Dependent Origination In the early texts, the process of the arising of dukkha is explicated through the teaching of dependent origination, which says that everything that exists or occurs is dependent on conditioning factors. The most basic formulation of dependent origination is given in the early texts as: 'It being thus, this comes about' (Pali: evam sati idam hoti). This can be taken to mean that certain phenomena only arise when there are other phenomena present, thus their arising is "dependent" on other phenomena. The philosopher Mark Siderits has outlined the basic idea of the Buddha's teaching of Dependent Origination of dukkha as follows: In numerous early texts, this basic principle is expanded with a list of phenomena that are said to be conditionally dependent, as a result of later elaborations, including Vedic cosmogenies as the basis for the first four links. According to Boisvert, nidana 3-10 correlate with the five skandhas. According to Richard Gombrich, the twelve-fold list is a combination of two previous lists, the second list beginning with tanha, "thirst", the cause of suffering as described in the second noble truth". According to Gombrich, the two lists were combined, resulting in contradictions in its reverse version. Anatta The Buddha saw his analysis of dependent origination as a "Middle Way" between "eternalism" (sassatavada, the idea that some essence exists eternally) and "annihilationism" (ucchedavada, the idea that we go completely out of existence at death). in this view, persons are just a causal series of impermanent psycho-physical elements, which are anatta, without an independent or permanent self. The Buddha instead held that all things in the world of our experience are transient and that there is no unchanging part to a person. According to Richard Gombrich, the Buddha's position is simply that "everything is process". The Buddha's arguments against an unchanging self rely on the scheme of the five skandhas, as can be seen in the Pali Anattalakkhaṇa Sutta (and its parallels in Gandhari and Chinese). In the early texts the Buddha teaches that all five aggregates, including consciousness (viññana, which was held by Brahmins to be eternal), arise due to dependent origination. Since they are all impermanent, one cannot regard any of the psycho-physical processes as an unchanging self. Even mental processes such as consciousness and will (cetana) are seen as being dependently originated and impermanent and thus do not qualify as a self (atman). The Buddha saw the belief in a self as arising from our grasping at and identifying with the various changing phenomena, as well as from ignorance about how things really are. Furthermore, the Buddha held that we experience suffering because we hold on to erroneous self views. As Rupert Gethin explains, for the Buddha, a person is Due to this view (termed ), the Buddha's teaching was opposed to all soul theories of his time, including the Jain theory of a "jiva" ("life monad") and the Brahmanical theories of atman (Pali: atta) and purusha. All of these theories held that there was an eternal unchanging essence to a person, which was separate from all changing experiences, and which transmigrated from life to life. The Buddha's anti-essentialist view still includes an understanding of continuity through rebirth, it is just the rebirth of a process (karma), not an essence like the atman. The path to liberation The Buddha taught a path (marga) of training to undo the samyojana, kleshas and āsavas and attain vimutti (liberation). This path taught by the Buddha is depicted in the early texts (most famously in the Pali Dhammacakkappavattana Sutta and its numerous parallel texts) as a "Middle Way" between sensual indulgence on one hand and mortification of the body on the other. A common presentation of the core structure of Buddha's teaching found in the early texts is that of the Four Noble Truths, which refers to the Noble Eightfold Path. According to Gethin, another common summary of the path to awakening wisely used in the early texts is "abandoning the hindrances, practice of the four establishments of mindfulness and development of the awakening factors". According to Rupert Gethin, in the Nikayas and Agamas, the Buddha's path is mainly presented in a cumulative and gradual "step by step" process, such as that outlined in the Samaññaphala Sutta. Other early texts like the Upanisa sutta (SN 12.23), present the path as reversions of the process of Dependent Origination. Bhāvanā, cultivation of wholesome states, is central to the Buddha's path. Common practices to this goal, which are shared by most of these early presentations of the path, include sila (ethical training), restraint of the senses (indriyasamvara), sati (mindfulness) and sampajañña (clear awareness), and the practice of dhyana, the cumulative development of wholesome states leading to a "state of perfect equanimity and awareness (upekkhā-sati-parisuddhi)". Dhyana is preceded and supported by various aspects of the path such as sense restraint and mindfulness, which is elaborated in the satipatthana-scheme, as taught in the Pali Satipatthana Sutta and the sixteen elements of Anapanasati, as taught in the Anapanasati Sutta. Jain and Brahmanical influences In various texts, the Buddha is depicted as having studied under two named teachers, Āḷāra Kālāma and Uddaka Rāmaputta. According to Alexander Wynne, these were yogis who taught doctrines and practices similar to those in the Upanishads. According to Johannes Bronkhorst, the "meditation without breath and reduced intake of food" which the Buddha practiced before his awakening are forms of asceticism which are similar to Jain practices. According to Richard Gombrich, the Buddha's teachings on Karma and Rebirth are a development of pre-Buddhist themes that can be found in Jain and Brahmanical sources, like the Brihadaranyaka Upanishad. Likewise, samsara, the idea that we are trapped in cycles of rebirth and that we should seek liberation from them through non-harming (ahimsa) and spiritual practices, pre-dates the Buddha and was likely taught in early Jainism. According to K.R. Norman, the Buddhist teaching of the three marks of existence may also reflect Upanishadic or other influences . The Buddhist practice called Brahma-vihara may have also originated from a Brahmanic term; but its usage may have been common in the sramana traditions. Scholarly views on the earliest teachings One method to obtain information on the oldest core of Buddhism is to compare the oldest versions of the Pali Canon and other texts, such as the surviving portions of Sarvastivada, Mulasarvastivada, Mahisasaka, Dharmaguptaka, and the Chinese Agamas. The reliability of these sources, and the possibility of drawing out a core of oldest teachings, is a matter of dispute. According to Lambert Schmithausen, there are three positions held by modern scholars of Buddhism with regard to the authenticity of the teachings contained in the Nikayas: "Stress on the fundamental homogeneity and substantial authenticity of at least a considerable part of the Nikayic materials". "Scepticism with regard to the possibility of retrieving the doctrine of earliest Buddhism". "Cautious optimism in this respect". Scholars such as Richard Gombrich, Akira Hirakawa, Alexander Wynne and A.K. Warder hold that these Early Buddhist Texts contain material that could possibly be traced to the Buddha. Richard Gombrich argues that since the content of the earliest texts "presents such originality, intelligence, grandeur and—most relevantly—coherence...it is hard to see it as a composite work." Thus he concludes they are "the work of one genius". Peter Harvey also agrees that "much" of the Pali Canon "must derive from his [the Buddha's] teachings". Likewise, A. K. Warder has written that "there is no evidence to suggest that it [the shared teaching of the early schools] was formulated by anyone other than the Buddha and his immediate followers." According to Alexander Wynne, "the internal evidence of the early Buddhist literature proves its historical authenticity." Other scholars of Buddhist studies have disagreed with the mostly positive view that the early Buddhist texts reflect the teachings of the historical Buddha, arguing that some teachings contained in the early texts are the authentic teachings of the Buddha, but not others. According to Tilmann Vetter, inconsistencies remain, and other methods must be applied to resolve those inconsistencies. According to Tilmann Vetter, the earliest core of the Buddhist teachings is the meditative practice of dhyāna, but "liberating insight" became an essential feature of the Buddhist tradition only at a later date. He posits that the Fourth Noble Truths, the Eightfold path and Dependent Origination, which are commonly seen as essential to Buddhism, are later formulations which form part of the explanatory framework of this "liberating insight". Lambert Schmithausen similarly argues that the mention of the four noble truths as constituting "liberating insight", which is attained after mastering the four dhyānas, is a later addition. Johannes Bronkhorst also argues that the four truths may not have been formulated in earliest Buddhism, and did not serve in earliest Buddhism as a description of "liberating insight". Edward Conze argued that the attempts of European scholars to reconstruct the original teachings of the Buddha were "all mere guesswork". Homeless life The early Buddhist texts depict the Buddha as promoting the life of a homeless and celibate "sramana", or mendicant, as the ideal way of life for the practice of the path. He taught that mendicants or "beggars" (bhikkhus) were supposed to give up all possessions and to own just a begging bowl and three robes. As part of the Buddha's monastic discipline, they were also supposed to rely on the wider lay community for the basic necessities (mainly food, clothing, and lodging). The Buddha's teachings on monastic discipline were preserved in the various Vinaya collections of the different early schools. Buddhist monastics, which included both monks and nuns, were supposed to beg for their food, were not allowed to store up food or eat after noon and they were not allowed to use gold, silver or any valuables. Society Critique of Brahmanism According to Bronkhorst, "the bearers of [the Brahmanical] tradition, the Brahmins, did not occupy a dominant position in the area in which the Buddha preached his message." Nevertheless, the Buddha was acquainted with Brahmanism, and in the early Buddhist Texts, the Buddha references Brahmanical devices. For example, in Samyutta Nikaya 111, Majjhima Nikaya 92 and Vinaya i 246 of the Pali Canon, the Buddha praises the Agnihotra as the foremost sacrifice and the Gayatri mantra as the foremost meter. In general, the Buddha critiques the Brahmanical religion and social system on certain key points. The Brahmin caste held that the Vedas were eternal revealed (sruti) texts. The Buddha, on the other hand, did not accept that these texts had any divine authority or value. The Buddha also did not see the Brahmanical rites and practices as useful for spiritual advancement. For example, in the Udāna, the Buddha points out that ritual bathing does not lead to purity, only "truth and morality" lead to purity. He especially critiqued animal sacrifice as taught in Vedas. The Buddha contrasted his teachings, which were taught openly to all people, with that of the Brahmins', who kept their mantras secret. The Buddha also critiqued the Brahmins' claims of superior birth and the idea that different castes and bloodlines were inherently pure or impure, noble or ignoble. In the Vasettha sutta the Buddha argues that the main difference among humans is not birth but their actions and occupations. According to the Buddha, one is a "Brahmin" (i.e. divine, like Brahma) only to the extent that one has cultivated virtue. Because of this the early texts report that he proclaimed: "Not by birth one is a Brahman, not by birth one is a non-Brahman; – by moral action one is a Brahman" The Aggañña Sutta explains all classes or varnas can be good or bad and gives a sociological explanation for how they arose, against the Brahmanical idea that they are divinely ordained. According to Kancha Ilaiah, the Buddha posed the first contract theory of society. The Buddha's teaching then is a single universal moral law, one Dharma valid for everybody, which is opposed to the Brahmanic ethic founded on "one's own duty" (svadharma) which depends on caste. Because of this, all castes including untouchables were welcome in the Buddhist order and when someone joined, they renounced all caste affiliation. Socio-political teachings The early texts depict the Buddha as giving a deflationary account of the importance of politics to human life. Politics is inevitable and is probably even necessary and helpful, but it is also a tremendous waste of time and effort, as well as being a prime temptation to allow ego to run rampant. Buddhist political theory denies that people have a moral duty to engage in politics except to a very minimal degree (pay the taxes, obey the laws, maybe vote in the elections), and it actively portrays engagement in politics and the pursuit of enlightenment as being conflicting paths in life. In the Aggañña Sutta, the Buddha teaches a history of how monarchy arose which according to Matthew J. Moore is "closely analogous to a social contract". The Aggañña Sutta also provides a social explanation of how different classes arose, in contrast to the Vedic views on social caste. Other early texts like the Cakkavatti-Sīhanāda Sutta and the Mahāsudassana Sutta focus on the figure of the righteous wheel turning leader (Cakkavatti). This ideal leader is one who promotes Dharma through his governance. He can only achieve his status through moral purity and must promote morality and Dharma to maintain his position. According to the Cakkavatti-Sīhanāda Sutta, the key duties of a Cakkavatti are: "establish guard, ward, and protection according to Dhamma for your own household, your troops, your nobles, and vassals, for Brahmins and householders, town and country folk, ascetics and Brahmins, for beasts and birds. let no crime prevail in your kingdom, and to those who are in need, give property." The sutta explains the injunction to give to the needy by telling how a line of wheel-turning monarchs falls because they fail to give to the needy, and thus the kingdom falls into infighting as poverty increases, which then leads to stealing and violence. In the Mahāparinibbāna Sutta, the Buddha outlines several principles that he promoted among the Vajjika tribal federation, which had a quasi-republican form of government. He taught them to "hold regular and frequent assemblies", live in harmony and maintain their traditions. The Buddha then goes on to promote a similar kind of republican style of government among the Buddhist Sangha, where all monks had equal rights to attend open meetings and there would be no single leader, since The Buddha also chose not to appoint one. Some scholars have argued that this fact signals that the Buddha preferred a republican form of government, while others disagree with this position. Worldly happiness As noted by Bhikkhu Bodhi, the Buddha as depicted in the Pali suttas does not exclusively teach a world transcending goal, but also teaches laypersons how to achieve worldly happiness (sukha). According to Bodhi, the "most comprehensive" of the suttas that focus on how to live as a layperson is the Sigālovāda Sutta (DN 31). This sutta outlines how a layperson behaves towards six basic social relationships: "parents and children, teacher and pupils, husband and wife, friend and friend, employer and workers, lay follower and religious guides." This Pali text also has parallels in Chinese and in Sanskrit fragments. In another sutta (Dīghajāṇu Sutta, AN 8.54) the Buddha teaches two types of happiness. First, there is the happiness visible in this very life. The Buddha states that four things lead to this happiness: "The accomplishment of persistent effort, the accomplishment of protection, good friendship, and balanced living." Similarly, in several other suttas, the Buddha teaches on how to improve family relationships, particularly on the importance of filial love and gratitude as well as marital well-being. Regarding the happiness of the next life, the Buddha (in the Dīghajāṇu Sutta) states that the virtues which lead to a good rebirth are: faith (in the Buddha and the teachings), moral discipline, especially keeping the five precepts, generosity, and wisdom (knowledge of the arising and passing of things). According to the Buddha of the suttas then, achieving a good rebirth is based on cultivating wholesome or skillful (kusala) karma, which leads to a good result, and avoiding unwholesome (akusala) karma. A common list of good karmas taught by the Buddha is the list of ten courses of action (kammapatha) as outlined in MN 41 Saleyyaka Sutta (and its Chinese parallel in SĀ 1042). Good karma is also termed merit (puñña), and the Buddha outlines three bases of meritorious actions: giving, moral discipline and meditation (as seen in AN 8:36). Physical characteristics Early sources depict the Buddha's as similar to other Buddhist monks. Various discourses describe how he "cut off his hair and beard" when renouncing the world. Likewise, Digha Nikaya 3 has a Brahmin describe the Buddha as a shaved or bald (mundaka) man. Digha Nikaya 2 also describes how king Ajatashatru is unable to tell which of the monks is the Buddha when approaching the sangha and must ask his minister to point him out. Likewise, in MN 140, a mendicant who sees himself as a follower of the Buddha meets the Buddha in person but is unable to recognize him. The Buddha is also described as being handsome and with a clear complexion (Digha I:115; Anguttara I:181), at least in his youth. In old age, however, he is described as having a stooped body, with slack and wrinkled limbs. Various Buddhist texts attribute to the Buddha a series of extraordinary physical characteristics, known as "the 32 Signs of the Great Man" (Skt. mahāpuruṣa lakṣaṇa). According to Anālayo, when they first appear in the Buddhist texts, these physical marks were initially held to be imperceptible to the ordinary person, and required special training to detect. Later though, they are depicted as being visible by regular people and as inspiring faith in the Buddha. These characteristics are described in the Digha Nikaya's (D, I:142). In other religions Hinduism This Hindu synthesis emerged after the lifetime of the Buddha, between 500–200 BCE and , under the pressure of the success of Buddhism and Jainism. In response to the success of Buddhism, Gautama also came to be regarded as the 9th avatar of Vishnu. Many Hindus claim that Buddha was Hindu and cite a belief that the Buddha is the ninth avatar of Vishnu in support. The adoption of the Buddha as an incarnation began at approximately the same time as Hinduism began to predominate and Buddhism to decline in India, the co-option into a list of avatars seen to be an aspect of Hindu efforts to decisively weaken Buddhist power and appeal in India. However, Buddha's teachings deny the authority of the Vedas and the concepts of Brahman-Atman. Consequently, Buddhism is generally classified as a nāstika school (heterodox, literally "It is not so") in contrast to the six orthodox schools of Hinduism. Islam Islamic prophet Dhu al-Kifl has been identified with the Buddha based on Surah 95:1 of the Qur'an, which references a fig tree – a symbol that does not feature prominently in the lives of any of the other prophets mentioned in the Qur'an. It has meanwhile been suggested that the name Al-Kifl could be a reference to Kapilavastu, the home of Siddartha Gautama as a boy. Classical Sunni scholar Tabari reports that Buddhist idols were brought from Afghanistan to Baghdad in the ninth century. Such idols had been sold in Buddhist temples next to a mosque in Bukhara, but he does not further discuss the role of Buddha. According to the works on Buddhism by Al-Biruni (973–after 1050), views regarding the exact identity of Buddha were diverse. Accordingly, some regarded him as the divine incarnate, others as an apostle of the angels or as an Ifrit and others as an apostle of God sent to the human race. By the 12th century, al-Shahrastani even compared Buddha to Khidr, described as an ideal human. Ibn Nadim, who was also familiar with Manichaean teachings, even identifies Buddha as a prophet, who taught a religion to "banish Satan", although he does not mention it explicitly. The Buddha is also regarded as a prophet by the minority Ahmadiyya sect. Christianity The Christian Saint Josaphat is based on the Buddha. The name comes from the Sanskrit Bodhisattva via Arabic Būdhasaf and Georgian Iodasaph. The only story in which St. Josaphat appears, Barlaam and Josaphat, is based on the life of the Buddha. Josaphat was included in earlier editions of the Roman Martyrology (feast-day 27 November)—though not in the Roman Missal—and in the Eastern Orthodox Church liturgical calendar (26 August). Other religions In the Baháʼí Faith, Buddha is regarded as one of the Manifestations of God. Some early Chinese Taoist-Buddhists thought the Buddha to be a reincarnation of Laozi. In the ancient Gnostic sect of Manichaeism, the Buddha is listed among the prophets who preached the word of God before Mani. In Sikhism, Buddha is mentioned as the 23rd avatar of Vishnu in the Chaubis Avtar, a composition in Dasam Granth traditionally and historically attributed to Guru Gobind Singh. Artistic depictions The earliest artistic depictions of the Buddha found at Bharhut and Sanchi are aniconic and symbolic. During this early aniconic period, the Buddha is depicted by other objects or symbols, such as an empty throne, a riderless horse, footprints, a Dharma wheel or a Bodhi tree. Since aniconism precludes single devotional figures, most representations are of narrative scenes from his life. These continued to be very important after the Buddha's person could be shown, alongside larger statues. The art at Sanchi also depicts Jataka tales, narratives of the Buddha in his past lives. Other styles of Indian Buddhist art depict the Buddha in human form, either standing, sitting crossed legged (often in the Lotus Pose) or lying down on one side. Iconic representations of the Buddha became particularly popular and widespread after the first century CE. Some of these depictions, particularly those of Gandharan Buddhism and Central Asian Buddhism, were influenced by Hellenistic art, a style known as Greco-Buddhist art. The subsequently influenced the art of East Asian Buddhist images, as well as those of Southeast Asian Theravada Buddhism.

Bridge

A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning. The word can be traced directly back to Proto-Indo-European *bʰrēw-. The origin of the word for the card game of the same name is unknown. History The simplest and earliest types of bridges were stepping stones. Neolithic people also built a form of boardwalk across marshes; examples of such bridges include the Sweet Track and the Post Track in England, approximately 6000 years old. Undoubtedly, ancient people would also have used log bridges; that is a timber bridge that fall naturally or are intentionally felled or placed across streams. Some of the first human-made bridges with significant span were probably intentionally felled trees. Among the oldest timber bridges is the Holzbrücke Rapperswil-Hurden bridge that crossed upper Lake Zürich in Switzerland; prehistoric timber pilings discovered to the west of the Seedamm causeway date back to 1523 BC. The first wooden footbridge there led across Lake Zürich; it was reconstructed several times through the late 2nd century AD, when the Roman Empire built a wooden bridge to carry transport across the lake. Between 1358 and 1360, Rudolf IV, Duke of Austria, built a 'new' wooden bridge across the lake that was used until 1878; it was approximately long and wide. On April 6, 2001, a reconstruction of the original wooden footbridge was opened; it is also the longest wooden bridge in Switzerland. The Arkadiko Bridge is one of four Mycenaean corbel arch bridges part of a former network of roads, designed to accommodate chariots, between the fort of Tiryns and town of Epidauros in the Peloponnese, in southern Greece. Dating to the Greek Bronze Age (13th century BC), it is one of the oldest arch bridges still in existence and use. Several intact arched stone bridges from the Hellenistic era can be found in the Peloponnese. The greatest bridge builders of antiquity were the ancient Romans. The Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs. Some stand today. An example is the Alcántara Bridge, built over the river Tagus, in Spain. The Romans also used cement, which reduced the variation of strength found in natural stone. One type of cement, called pozzolana, consisted of water, lime, sand, and volcanic rock. Brick and mortar bridges were built after the Roman era, as the technology for cement was lost (then later rediscovered). In India, the Arthashastra treatise by Kautilya mentions the construction of dams and bridges. A Mauryan bridge near Girnar was surveyed by James Princep. The bridge was swept away during a flood, and later repaired by Puspagupta, the chief architect of emperor Chandragupta I. The use of stronger bridges using plaited bamboo and iron chain was visible in India by about the 4th century. A number of bridges, both for military and commercial purposes, were constructed by the Mughal administration in India. Although large Chinese bridges of wooden construction existed at the time of the Warring States period, the oldest surviving stone bridge in China is the Zhaozhou Bridge, built from 595 to 605 AD during the Sui dynasty. This bridge is also historically significant as it is the world's oldest open-spandrel stone segmental arch bridge. European segmental arch bridges date back to at least the Alconétar Bridge (approximately 2nd century AD), while the enormous Roman era Trajan's Bridge (105 AD) featured open-spandrel segmental arches in wooden construction. Rope bridges, a simple type of suspension bridge, were used by the Inca civilization in the Andes mountains of South America, just prior to European colonization in the 16th century. The Ashanti built bridges over streams and rivers. They were constructed by pounding four large forked tree trunks into the stream bed, placing beams along these forked pillars, then positioning cross-beams that were finally covered with four to six inches of dirt. During the 18th century, there were many innovations in the design of timber bridges by Hans Ulrich Grubenmann, Johannes Grubenmann, and others. The first book on bridge engineering was written by Hubert Gautier in 1716. A major breakthrough in bridge technology came with the erection of the Iron Bridge in Shropshire, England in 1779. It used cast iron for the first time as arches to cross the river Severn. With the Industrial Revolution in the 19th century, truss systems of wrought iron were developed for larger bridges, but iron does not have the tensile strength to support large loads. With the advent of steel, which has a high tensile strength, much larger bridges were built, many using the ideas of Gustave Eiffel. In Canada and the United States, numerous timber covered bridges were built in the late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Some covered bridges were also built in Asia. In later years, some were partly made of stone or metal but the trusses were usually still made of wood; in the United States, there were three styles of trusses, the Queen Post, the Burr Arch and the Town Lattice. Hundreds of these structures still stand in North America. They were brought to the attention of the general public in the 1990s by the novel, movie, and play The Bridges of Madison County. In 1927 welding pioneer Stefan Bryła designed the first welded road bridge in the world, the Maurzyce Bridge which was later built across the river Słudwia at Maurzyce near Łowicz, Poland in 1929. In 1995, the American Welding Society presented the Historic Welded Structure Award for the bridge to Poland. Types of bridges Bridges can be categorized in several different ways. Common categories include the type of structural elements used, by what they carry, whether they are fixed or movable, and by the materials used. Structure types Bridges may be classified by how the actions of tension, compression, bending, torsion and shear are distributed through their structure. Most bridges will employ all of these to some degree, but only a few will predominate. The separation of forces and moments may be quite clear. In a suspension or cable-stayed bridge, the elements in tension are distinct in shape and placement. In other cases the forces may be distributed among a large number of members, as in a truss. Some Engineers sub-divide 'beam' bridges into slab, beam-and-slab and box girder on the basis of their cross-section. A slab can be solid or voided (though this is no longer favored for inspectability reasons) while beam-and-slab consists of concrete or steel girders connected by a concrete slab. A box-girder cross-section consists of a single-cell or multi-cellular box. In recent years, integral bridge construction has also become popular. Fixed or movable bridges Most bridges are fixed bridges, meaning they have no moving parts and stay in one place until they fail or are demolished. Temporary bridges, such as Bailey bridges, are designed to be assembled, taken apart, transported to a different site, and re-used. They are important in military engineering and are also used to carry traffic while an old bridge is being rebuilt. Movable bridges are designed to move out of the way of boats or other kinds of traffic, which would otherwise be too tall to fit. These are generally electrically powered. The Tank bridge transporter (TBT) has the same cross-country performance as a tank even when fully loaded. It can deploy, drop off and load bridges independently, but it cannot recover them. Double-decked bridges Double-decked (or double-decker) bridges have two levels, such as the George Washington Bridge, connecting New York City to Bergen County, New Jersey, US, as the world's busiest bridge, carrying 102 million vehicles annually; truss work between the roadway levels provided stiffness to the roadways and reduced movement of the upper level when the lower level was installed three decades after the upper level. The Tsing Ma Bridge and Kap Shui Mun Bridge in Hong Kong have six lanes on their upper decks, and on their lower decks there are two lanes and a pair of tracks for MTR metro trains. Some double-decked bridges only use one level for street traffic; the Washington Avenue Bridge in Minneapolis reserves its lower level for automobile and light rail traffic and its upper level for pedestrian and bicycle traffic (predominantly students at the University of Minnesota). Likewise, in Toronto, the Prince Edward Viaduct has five lanes of motor traffic, bicycle lanes, and sidewalks on its upper deck; and a pair of tracks for the Bloor–Danforth subway line on its lower deck. The western span of the San Francisco–Oakland Bay Bridge also has two levels. Robert Stephenson's High Level Bridge across the River Tyne in Newcastle upon Tyne, completed in 1849, is an early example of a double-decked bridge. The upper level carries a railway, and the lower level is used for road traffic. Other examples include Britannia Bridge over the Menai Strait and Craigavon Bridge in Derry, Northern Ireland. The Oresund Bridge between Copenhagen and Malmö consists of a four-lane highway on the upper level and a pair of railway tracks at the lower level. Tower Bridge in London is different example of a double-decked bridge, with the central section consisting of a low-level bascule span and a high-level footbridge. Viaducts A viaduct is made up of multiple bridges connected into one longer structure. The longest and some of the highest bridges are viaducts, such as the Lake Pontchartrain Causeway and Millau Viaduct. Multi-way bridge A multi-way bridge has three or more separate spans which meet near the center of the bridge. Multi-way bridges with only three spans appear as a "T" or "Y" when viewed from above. Multi-way bridges are extremely rare. The Tridge, Margaret Bridge, and Zanesville Y-Bridge are examples. Bridge types by use A bridge can be categorized by what it is designed to carry, such as trains, pedestrian or road traffic (road bridge), a pipeline (Pipe bridge) or waterway for water transport or barge traffic. An aqueduct is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height. A road-rail bridge carries both road and rail traffic. Overway is a term for a bridge that separates incompatible intersecting traffic, especially road and rail. A bridge can carry overhead power lines as does the Storstrøm Bridge. Some bridges accommodate other purposes, such as the tower of Nový Most Bridge in Bratislava, which features a restaurant, or a bridge-restaurant which is a bridge built to serve as a restaurant. Other suspension bridge towers carry transmission antennas. Conservationists use wildlife overpasses to reduce habitat fragmentation and animal-vehicle collisions. The first animal bridges sprung up in France in the 1950s, and these types of bridges are now used worldwide to protect both large and small wildlife. Bridges are subject to unplanned uses as well. The areas underneath some bridges have become makeshift shelters and homes to homeless people, and the undertimbers of bridges all around the world are spots of prevalent graffiti. Some bridges attract people attempting suicide, and become known as suicide bridges. Bridge types by material The materials used to build the structure are also used to categorize bridges. Until the end of the 18th century, bridges were made out of timber, stone and masonry. Modern bridges are currently built in concrete, steel, fiber reinforced polymers (FRP), stainless steel or combinations of those materials. Living bridges have been constructed of live plants such as Ficus elastica tree roots in India and wisteria vines in Japan. Analysis and design Unlike buildings whose design is led by architects, bridges are usually designed by engineers. This follows from the importance of the engineering requirements; namely spanning the obstacle and having the durability to survive, with minimal maintenance, in an aggressive outdoor environment. Bridges are first analysed; the bending moment and shear force distributions are calculated due to the applied loads. For this, the finite element method is the most popular. The analysis can be one-, two-, or three-dimensional. For the majority of bridges, a two-dimensional plate model (often with stiffening beams) is sufficient or an upstand finite element model. On completion of the analysis, the bridge is designed to resist the applied bending moments and shear forces, section sizes are selected with sufficient capacity to resist the stresses. Many bridges are made of prestressed concrete which has good durability properties, either by pre-tensioning of beams prior to installation or post-tensioning on site. In most countries, bridges, like other structures, are designed according to Load and Resistance Factor Design (LRFD) principles. In simple terms, this means that the load is factored up by a factor greater than unity, while the resistance or capacity of the structure is factored down, by a factor less than unity. The effect of the factored load (stress, bending moment) should be less than the factored resistance to that effect. Both of these factors allow for uncertainty and are greater when the uncertainty is greater. Aesthetics Most bridges are utilitarian in appearance, but in some cases, the appearance of the bridge can have great importance. Often, this is the case with a large bridge that serves as an entrance to a city, or crosses over a main harbor entrance. These are sometimes known as signature bridges. Designers of bridges in parks and along parkways often place more importance on aesthetics, as well. Examples include the stone-faced bridges along the Taconic State Parkway in New York. Generally bridges are more aesthetically pleasing if they are simple in shape, the deck is thinner (in proportion to its span), the lines of the structure are continuous, and the shapes of the structural elements reflect the forces acting on them. To create a beautiful image, some bridges are built much taller than necessary. This type, often found in east-Asian style gardens, is called a Moon bridge, evoking a rising full moon. Other garden bridges may cross only a dry bed of stream-washed pebbles, intended only to convey an impression of a stream. Often in palaces, a bridge will be built over an artificial waterway as symbolic of a passage to an important place or state of mind. A set of five bridges cross a sinuous waterway in an important courtyard of the Forbidden City in Beijing, China. The central bridge was reserved exclusively for the use of the Emperor and Empress, with their attendants. Bridge maintenance The estimated life of bridges varies between 25 and 80 years depending on location and material. However, bridges may age hundred years with proper maintenance and rehabilitation. Bridge maintenance consisting of a combination of structural health monitoring and testing. This is regulated in country-specific engineer standards and includes an ongoing monitoring every three to six months, a simple test or inspection every two to three years and a major inspection every six to ten years. In Europe, the cost of maintenance is considerable and is higher in some countries than spending on new bridges. The lifetime of welded steel bridges can be significantly extended by aftertreatment of the weld transitions. This results in a potential high benefit, using existing bridges far beyond the planned lifetime. Bridge traffic loading While the response of a bridge to the applied loading is well understood, the applied traffic loading itself is still the subject of research. This is a statistical problem as loading is highly variable, particularly for road bridges. Load Effects in bridges (stresses, bending moments) are designed for using the principles of Load and Resistance Factor Design. Before factoring to allow for uncertainty, the load effect is generally considered to be the maximum characteristic value in a specified return period. Notably, in Europe, it is the maximum value expected in 1000 years. Bridge standards generally include a load model, deemed to represent the characteristic maximum load to be expected in the return period. In the past, these load models were agreed by standard drafting committees of experts but today, this situation is changing. It is now possible to measure the components of bridge traffic load, to weigh trucks, using weigh-in-motion (WIM) technologies. With extensive WIM databases, it is possible to calculate the maximum expected load effect in the specified return period. This is an active area of research, addressing issues of opposing direction lanes, side-by-side (same direction) lanes, traffic growth, permit/non-permit vehicles and long-span bridges (see below). Rather than repeat this complex process every time a bridge is to be designed, standards authorities specify simplified notional load models, notably HL-93, intended to give the same load effects as the characteristic maximum values. The Eurocode is an example of a standard for bridge traffic loading that was developed in this way. Traffic loading on long span bridges Most bridge standards are only applicable for short and medium spans - for example, the Eurocode is only applicable for loaded lengths up to 200 m. Longer spans are dealt with on a case-by-case basis. It is generally accepted that the intensity of load reduces as span increases because the probability of many trucks being closely spaced and extremely heavy reduces as the number of trucks involved increases. It is also generally assumed that short spans are governed by a small number of trucks traveling at high speed, with an allowance for dynamics. Longer spans on the other hand, are governed by congested traffic and no allowance for dynamics is needed. Calculating the loading due to congested traffic remains a challenge as there is a paucity of data on inter-vehicle gaps, both within-lane and inter-lane, in congested conditions. Weigh-in-Motion (WIM) systems provide data on inter-vehicle gaps but only operate well in free flowing traffic conditions. Some authors have used cameras to measure gaps and vehicle lengths in jammed situations and have inferred weights from lengths using WIM data. Others have used microsimulation to generate typical clusters of vehicles on the bridge. Bridge vibration Bridges vibrate under load and this contributes, to a greater or lesser extent, to the stresses. Vibration and dynamics are generally more significant for slender structures such as pedestrian bridges and long-span road or rail bridges. One of the most famous examples is the Tacoma Narrows Bridge that collapsed shortly after being constructed due to excessive vibration. More recently, the Millennium Bridge in London vibrated excessively under pedestrian loading and was closed and retrofitted with a system of dampers. For smaller bridges, dynamics is not catastrophic but can contribute an added amplification to the stresses due to static effects. For example, the Eurocode for bridge loading specifies amplifications of between 10% and 70%, depending on the span, the number of traffic lanes and the type of stress (bending moment or shear force). Vehicle-bridge dynamic interaction There have been many studies of the dynamic interaction between vehicles and bridges during vehicle crossing events. Fryba did pioneering work on the interaction of a moving load and an Euler-Bernoulli beam. With increased computing power, vehicle-bridge interaction (VBI) models have become ever more sophisticated. The concern is that one of the many natural frequencies associated with the vehicle will resonate with the bridge first natural frequency. The vehicle-related frequencies include body bounce and axle hop but there are also pseudo-frequencies associated with the vehicle's speed of crossing and there are many frequencies associated with the surface profile. Given the wide variety of heavy vehicles on road bridges, a statistical approach has been suggested, with VBI analyses carried out for many statically extreme loading events. Bridge failures The failure of bridges is of special concern for structural engineers in trying to learn lessons vital to bridge design, construction and maintenance. The failure of bridges first assumed national interest in Britain during the Victorian era when many new designs were being built, often using new materials, with some of them failing catastrophically. In the United States, the National Bridge Inventory tracks the structural evaluations of all bridges, including designations such as "structurally deficient" and "functionally obsolete". Bridge health monitoring There are several methods used to monitor the condition of large structures like bridges. Many long-span bridges are now routinely monitored with a range of sensors, including strain transducers, accelerometers, tiltmeters, and GPS. Accelerometers have the advantage that they are inertial, i.e., they do not require a reference point to measure from. This is often a problem for distance or deflection measurement, especially if the bridge is over water. Crowdsourcing bridge conditions by accessing data passively captured by cell phones, which routinely include accelerometers and GPS sensors, has been suggested as an alternative to including sensors during bridge construction and an augment for professional examinations. An option for structural-integrity monitoring is "non-contact monitoring", which uses the Doppler effect (Doppler shift). A laser beam from a Laser Doppler Vibrometer is directed at the point of interest, and the vibration amplitude and frequency are extracted from the Doppler shift of the laser beam frequency due to the motion of the surface. The advantage of this method is that the setup time for the equipment is faster and, unlike an accelerometer, this makes measurements possible on multiple structures in as short a time as possible. Additionally, this method can measure specific points on a bridge that might be difficult to access. However, vibrometers are relatively expensive and have the disadvantage that a reference point is needed to measure from. Snapshots in time of the external condition of a bridge can be recorded using Lidar to aid bridge inspection. This can provide measurement of the bridge geometry (to facilitate the building of a computer model) but the accuracy is generally insufficient to measure bridge deflections under load. While larger modern bridges are routinely monitored electronically, smaller bridges are generally inspected visually by trained inspectors. There is considerable research interest in the challenge of smaller bridges as they are often remote and do not have electrical power on site. Possible solutions are the installation of sensors on a specialist inspection vehicle and the use of its measurements as it drives over the bridge to infer information about the bridge condition. These vehicles can be equipped with accelerometers, gyrometers, Laser Doppler Vibrometers and some even have the capability to apply a resonant force to the road surface in order to dynamically excite the bridge at its resonant frequency.

Board game

Board games are tabletop games that typically use . These pieces are moved or placed on a pre-marked board (playing surface) and often include elements of table, card, role-playing, and miniatures games as well. Many board games feature a competition between two or more players. To show a few examples: in checkers (British English name 'draughts'), a player wins by capturing all opposing pieces, while Eurogames often end with a calculation of final scores. Pandemic is a cooperative game where players all win or lose as a team, and peg solitaire is a puzzle for one person. There are many varieties of board games. Their representation of real-life situations can range from having no inherent theme, such as checkers, to having a specific theme and narrative, such as Cluedo. Rules can range from the very simple, such as in snakes and ladders; to deeply complex, as in Advanced Squad Leader. Play components now often include custom figures or shaped counters, and distinctively shaped player pieces commonly known as as well as traditional cards and dice. The time required to learn or master varies greatly from game to game, but is not necessarily related to the number or complexity of rules; for example, chess or Go possess relatively simple but have great strategic depth. History Ancient Classical board games are divided into four categories: race games (such as pachisi), space games (such as noughts and crosses), chase games (such as hnefatafl), and games of displacement (such as chess). Board games have been played, traveled, and evolved in most cultures and societies throughout history. Several important historical sites, artifacts, and documents shed light on early board games such as Jiroft civilization game boards in Iran. Senet, found in Predynastic and First Dynasty burials of Egypt, and 3100 BC respectively, is the oldest board game known to have existed. Senet was pictured in a fresco painting found in Merknera's tomb (3300–2700 BC). Also from predynastic Egypt is mehen. Hounds and jackals, another ancient Egyptian board game, appeared around 2000 BC. The first complete set of this game was discovered from a Theban tomb that dates to the 13th dynasty. This game was also popular in Mesopotamia and the Caucasus. Backgammon originated in ancient Mesopotamia about 5,000 years ago. Ashtapada, chess, pachisi and chaupar originated in India. Go and liubo originated in China. Patolli originated in Mesoamerica played by the ancient Aztecs and the royal game of Ur was found in the royal tombs of Ur, dating to Mesopotamia 4,600 years ago. European Board games have a long tradition in Europe. The oldest records of board gaming in Europe date back to Homer's Iliad (written in the 8th century BC), in which he mentions the Ancient Greek game of petteia. This game of petteia would later evolve into the Roman ludus latrunculorum. Board gaming in ancient Europe was not unique to the Greco-Roman world, with records estimating that the ancient Norse game of hnefatafl was developed sometime before 400AD. In ancient Ireland, the game of fidchell or ficheall, is said to date back to at least 144 AD, though this is likely an anachronism. A fidchell board dating from the 10th century has been uncovered in Co. Westmeath, Ireland. The association of dice and cards with gambling led to all dice games except backgammon being treated as lotteries by dice in the gaming acts of 1710 and 1845. Early board game producers in the second half of the eighteenth century were mapmakers. The global popularization of Board Games, with special themes and branding, coincided with the formation of the global dominance of the British Empire. John Wallis was an English board game publisher, bookseller, map/chart seller, printseller, music seller, and cartographer. With his sons John Wallis Jr. and Edward Wallis, he was one of the most prolific publishers of board games of the late 18th and early 19th centuries. John Betts' A Tour of the British Colonies and Foreign Possessions and William Spooner's A Voyage of Discovery were popular in the British empire. is a genre of wargaming developed in 19th century Prussia to teach battle tactics to officers. American The board game Traveller's Tour Through the United States and its sister game Traveller's Tour Through Europe were published by New York City bookseller F. & R. Lockwood in 1822 and claim the distinction of being the first board games published in the United States. Margaret Hofer described the period of the 1880s–1920s as "The Golden Age" of board gaming in America. Board game popularity was boosted, like that of many items, through mass production, which made them cheaper and more easily available. Although there are no detailed statistics, some scholars suggest that the 20th century saw a decline in the popularity of the hobby. Chinese, Arabic, and Indian Outside of Europe and the U.S., many traditional board games are popular. In China, Go and many variations of chess are popular. In Africa and the Middle East, mancala is a popular board game archetype with many regional variations. In India, a community game called Carrom is popular. Modern The late 1990s onwards have seen substantial growth in the reach and market of board games. This has been attributed to, among other factors, the Internet, which has made it easier for people to find out about games and to find opponents to play against, as well as with a general increase in leisure time and consumer spending on entertainment. Around the year 2000, the board gaming industry began significant growth, with companies producing a rising number of new games to be sold to a growing worldwide audience. In the 2010s, several publications referred to board games as having a new Golden Age, though some board-gamers prefer to call it a 'renaissance', as The Golden Age is both predefined and a common term. Board game venues are also growing in popularity; in 2016, over 5,000 board game cafés opened in the U.S. alone. Board game cafés are also reported to be very popular in China. Board games have also been used as a mechanism for science communication. Luck, strategy, and diplomacy Some games, such as chess, depend completely on player skill, while many children's games such as Candy Land and snakes and ladders require no decisions by the players and are decided purely by luck. Many games require some level of both skill and luck. A player may be hampered by bad luck in backgammon, Monopoly, or Risk; but over many games, a skilled player will win more often. The elements of luck can also make for more excitement at times, and allow for more diverse and multifaceted strategies, as concepts such as expected value and risk management must be considered. Luck may be introduced into a game by several methods. The use of dice of various sorts goes back to the earliest board games. These can decide everything from how many steps a player moves their token, as in Monopoly, to how their forces fare in battle, as in Risk, or which resources a player gains, as in Catan. Other games such as Sorry! use a deck of special cards that, when shuffled, create randomness. Scrabble does something similar with randomly picked letters. Other games use spinners, timers of random length, or other sources of randomness. German-style board games are notable for often having fewer elements of luck than many North American board games. Another important aspect of some games is diplomacy, that is, players, making deals with one another. Negotiation generally features only in games with three or more players, cooperative games being the exception. An important facet of Catan, for example, is convincing players to trade with you rather than with opponents. In Risk, two or more players may team up against others. Easy diplomacy involves convincing other players that someone else is winning and should therefore be teamed up against. Advanced diplomacy (e.g., in the aptly named game Diplomacy) consists of making elaborate plans together, with the possibility of betrayal. In perfect information games, such as chess, each player has complete information on the state of the game, but in other games, such as Tigris and Euphrates or Stratego, some information is hidden from players. This makes finding the best move more difficult and may involve estimating probabilities by the opponents. Software Many board games are now available as video games. These are aptly termed digital board games, and their distinguishing characteristic compared to traditional board games is they can now be played online against a computer or other players. Some websites (such as boardgamearena.com, yucata.de, etc.) allow play in real time and immediately show the opponents' moves, while others use email to notify the players after each move. The Internet and cheaper home printing has also influenced board games via print-and-play games that may be purchased and printed. Some games use external media such as audio cassettes or DVDs in accompaniment to the game. There are also virtual tabletop programs that allow online players to play a variety of existing and new board games through tools needed to manipulate the game board but do not necessarily enforce the game's rules, leaving this up to the players. There are generalized programs such as Vassal, Tabletop Simulator and Tabletopia that can be used to play any board or card game, while programs like Roll20 and Fantasy Grounds that are more specialized for role-playing games. Some of these virtual tabletops have worked with the license holders to allow for use of their game's assets within the program; for example, Fantasy Grounds has licenses for both Dungeons & Dragons and Pathfinder materials, while Tabletop Simulator allows game publishers to provide paid downloadable content for their games. However, as these games offer the ability to add in the content through user modifications, there are also unlicensed uses of board game assets available through these programs. Market While the board gaming market is estimated to be smaller than that for video games, it has also experienced significant growth from the late 1990s. A 2012 article in The Guardian described board games as "making a comeback". Other expert sources suggest that board games never went away, and that board games have remained a popular leisure activity which has only grown over time. Another from 2014 gave an estimate that put the growth of the board game market at "between 25% and 40% annually" since 2010, and described the current time as the "golden era for board games". The rise in board game popularity has been attributed to quality improvement (more elegant mechanics, , artwork, and graphics) as well as increased availability thanks to sales through the Internet. Crowd-sourcing for board games is a large facet of the market, with $233 million raised on Kickstarter in 2020. A 1991 estimate for the global board game market was over $1.2 billion. A 2001 estimate for the United States "board games and puzzle" market gave a value of under $400 million, and for United Kingdom, of about £50 million. A 2009 estimate for the Korean market was put at 800 million won, and another estimate for the American board game market for the same year was at about $800 million. A 2011 estimate for the Chinese board game market was at over 10 billion yuan. A 2013 estimate put the size of the German toy market at 2.7 billion euros (out of which the board games and puzzle market is worth about 375 million euros), and Polish markets at 2 billion and 280 million zlotys, respectively. In 2009, Germany was considered to be the best market per capita, with the highest number of games sold per individual. Hobby board games Some academics, such as Erica Price and Marco Arnaudo, have differentiated "hobby" board games and gamers from other board games and gamers. A 2014 estimate placed the U.S. and Canada market for hobby board games (games produced for a "gamer" market) at only $75 million, with the total size of what it defined as the "hobby game market" ("the market for those games regardless of whether they’re sold in the hobby channel or other channels,") at over $700 million. A similar 2015 estimate suggested a hobby game market value of almost $900 million. Research A dedicated field of research into gaming exists, known as game studies or ludology. While there has been a fair amount of scientific research on the psychology of older board games (e.g., chess, Go, mancala), less has been done on contemporary board games such as Monopoly, Scrabble, and Risk, and especially modern board games such as Catan, Agricola, and Pandemic. Much research has been carried out on chess, partly because many tournament players are publicly ranked in national and international lists, which makes it possible to compare their levels of expertise. The works of Adriaan de Groot, William Chase, Herbert A. Simon, and Fernand Gobet have established that knowledge, more than the ability to anticipate moves, plays an essential role in chess-playing ability. Linearly arranged board games have improved children's spatial numerical understanding. This is because the game is similar to a number line in that they promote a linear understanding of numbers rather than the innate logarithmic one. Research studies show that board games such as Snakes and Ladders result in children showing significant improvements in aspects of basic number skills such as counting, recognizing numbers, numerical estimation, and number comprehension. They also practice fine motor skills each time they grasp a game piece. Playing board games has also been tied to improving children's executive functions and help reduce risks of dementia for the elderly. Related to this is a growing academic interest in the topic of game accessibility, culminating in the development of guidelines for assessing the accessibility of modern tabletop games and the extent to which they are playable for people with disabilities. Additionally, board games can be therapeutic. Bruce Halpenny, a games inventor said when interviewed about his game, The Great Train Robbery:With crime you deal with every basic human emotion and also have enough elements to combine action with melodrama. The player's imagination is fired as they plan to rob the train. Because of the gamble, they take in the early stage of the game there is a build-up of tension, which is immediately released once the train is robbed. Release of tension is therapeutic and useful in our society because most jobs are boring and repetitive. Playing games has been suggested as a viable addition to the traditional educational curriculum if the content is appropriate and the gameplay informs students on the curriculum content. Categories There are several ways in which board games can be classified, and considerable overlap may exist, so that a game belongs to several categories. H. J. R. Murray's A History of Board Games Other Than Chess (1952) has been called the first attempt to develop a "scheme for the classification of board games". David Parlett's Oxford History of Board Games (1999) defines four primary categories: race games (where the goal is to be the first to move all one's pieces to the final destination), space games (in which the object is to arrange the pieces into some special configuration), chase games (asymmetrical games, where players start the game with different sets of pieces and objectives) and displace games (where the main objective is the capture the opponents' pieces). Parlett also distinguishes between abstract and thematic games, the latter having a specific theme or frame narrative (ex. regular chess versus, for example, Star Wars-themed chess). The following is a list of some of the most common game categories: Abstract strategy games – e.g. chess, checkers, Go, reversi, tafl games, or modern games such as Abalone, Dameo, Stratego, Hive, or GIPF Alignment games – e.g. renju, gomoku, Connect6, Nine men's morris, or tic-tac-toe Auction games – e.g. Hoity Toity, Power Grid Chess variants – traditional variants e.g. shogi, xiangqi, or janggi; modern variants e.g. Chess960, Grand Chess, Hexagonal chess, or Alice Chess Configuration games – e.g. Lines of Action, Hexade, or Entropy Connection games – e.g. TwixT, Hex, or Havannah Cooperative games – e.g. Max the Cat, Caves and Claws, or Pandemic Count and capture games – e.g. mancala games Cross and circle games – e.g. Yut, Ludo, or Aggravation Deduction games – e.g. Mastermind or Black Box Dexterity games – e.g. Tumblin' Dice or Pitch Car Economic simulation games – e.g. The Business Game, Monopoly, The Game of Life, Power Grid, or Food Chain Magnate Educational games – e.g. Arthur Saves the Planet, Cleopatra and the Society of Architects, or Shakespeare: The Bard Game Elimination games – e.g. draughts, Alquerque, Fanorona, Yoté, or Surakarta Family games – e.g. Roll Through the Ages, Birds on a Wire, or For Sale Fantasy games – e.g. Shadows Over Camelot German-style board games or Eurogames – e.g. Catan, Carcassonne, Decatur • The Game, Carson City, or Puerto Rico Guessing games – e.g. Pictionary or Battleship Hidden-movement games – e.g. Clue or Escape from the Aliens in Outer Space Hidden-role games – e.g. Mafia or The Resistance Historical simulation games – e.g. Through the Ages or Railways of the World Horror games – e.g. Arkham Horror Large multiplayer games – e.g. Take It Easy or Swat (2010) Learning/communication non-competitive games – e.g. The Ungame (1972) Mancala games – e.g. Wari, Oware, or The Glass Bead Game Multiplayer games – e.g. Risk, Monopoly, or Four-player chess Musical games – e.g. Spontuneous Negotiation games – e.g. Diplomacy Paper-and-pencil games – e.g. Tic-tac-toe or Dots and Boxes Physical skill games – e.g. Camp Granada Position games (no captures; win by leaving the opponent unable to move) – e.g. kōnane, mū tōrere, or the L game Race games – e.g. Pachisi, backgammon, snakes and ladders, hyena chase, or Worm Up Role-playing games – e.g. Dungeons & Dragons Roll-and-move games – e.g. Monopoly or Life Running-fight games – e.g. bul Share-buying games (games in which players buy stakes in each other's positions) – typically longer economic-management games, e.g. Acquire or Panamax Single-player puzzle games – e.g. peg solitaire or Sudoku Spiritual development games (games with no winners or losers) – e.g. Transformation Game or Psyche's Key Stacking games – e.g. Lasca or DVONN Storytelling games – e.g. Dixit or Tales of the Arabian Nights Territory games – e.g. Go or Reversi Tile-based games – e.g. Carcassonne, Scrabble, Tigris and Euphrates, or Evo Train games – e.g. Ticket to Ride, Steam, or 18xx Trivia games – e.g. Trivial Pursuit Two-player-only themed games – e.g. En Garde or Dos de Mayo Unequal forces (or "hunt") games – e.g. fox and geese or tablut Wargames – ranging from Risk, Diplomacy, or Axis & Allies, to Attack! or Conquest of the Empire Word games – e.g. Scrabble, Boggle, Anagrams, or What's My Word? (2010) Glossary Although many board games have a jargon all their own, there is a generalized terminology to describe concepts applicable to basic game mechanics and attributes common to nearly all board games.

Baruch Spinoza

Baruch (de) Spinoza (24 November 1632 – 21 February 1677) was a philosopher of Portuguese-Jewish origin, born in Amsterdam, the Dutch Republic, and mostly known under his Latinized pen name Benedictus de Spinoza. One of the foremost and seminal thinkers of the Enlightenment, modern biblical criticism, and 17th-century Rationalism, including modern conceptions of the self and the universe, he came to be considered "one of the most important philosophers—and certainly the most radical—of the early modern period". Inspired by Stoicism, Jewish Rationalism, Machiavelli, Hobbes, Descartes, and a variety of heterodox Christian thinkers of his day. His controversial ideas challenged the divine origin of the Hebrew Bible, the nature of God, and the earthly power wielded by religious authorities, Jewish and Christian alike. He was frequently called an "atheist" by contemporaries, although nowhere in his work does Spinoza argue against the existence of God. Spinoza was raised in the Portuguese-Jewish community of Amsterdam, where his father Michael was a leading figure. His schooling was curtailed, and he joined his father's importing business, following the unexpected death of his older brother. The previously prosperous business was in deep trouble when his father died in 1654. While an active member of the synagogue, Spinoza developed highly controversial ideas regarding the authenticity of the Hebrew Bible, the nature of the Divine, and questioned rabbinic authority, but kept his views to himself until 1655. The break with rabbinic authorities coincided with the collapse of the family business and the loss of his honored position within the synagogue as a financial supporter. When he openly defied rabbinic authorities in 1655-56, they issued a herem () against him, expelling him permanently from the congregation; he was shunned by Jewish society at age 23, including by his own family. After his expulsion, Spinoza lived an outwardly simple life as an optical lens grinder. But the center of his life was philosophy, and he had a dedicated clandestine circle of supporters, a philosophical sect, who met in person to discuss the writings he shared with them. The secrecy was necessary because his ideas were so explosive, with his 1670 anonymously published Tractatus Theologico-Politicus (TTP) denounced as "A book forged in hell". He died at the age of 44 in 1677 from a lung illness, perhaps tuberculosis, and was buried in a Protestant cemetery in The Hague. His unpublished manuscripts were swiftly removed from his lodgings, to prevent their destruction by authorities; his circle of supporters prepared his works with speed and secrecy for posthumous publication in both their original Latin and Dutch. In June 1678—just over a year after Spinoza's death—the States of Holland, controlled by the Dutch Reformed Church, banned his entire works, since they "contain very many profane, blasphemous and atheistic propositions." The prohibition was sweeping, and included the owning, reading, distribution, copying, and restating of Spinoza's books, and even the reworking of his fundamental ideas. Shortly after (1679/1690) his books were added to the Catholic Church's Index of Forbidden Books. Spinoza's philosophy encompasses nearly every area of philosophical discourse, including metaphysics, epistemology, political philosophy, ethics, philosophy of mind, and philosophy of science. It earned Spinoza an enduring reputation as one of the most important and original thinkers of the seventeenth century. Spinoza's philosophy is largely contained in two books: the Theologico-Political Treatise, published anonymously in his lifetime in Latin, and the Ethics, published posthumously. He also left behind a number of letters that help to illuminate his ideas and provide some insight into what may have been motivating his views. Although cautious in his lifetime about publication, his death and his stalwart supporters' efforts to publish his work in Latin and in Dutch allowed his ideas to circulate to a wider educated readership, despite authorities' concerted efforts to suppress them. He has been called "the renegade Jew who gave us modernity." Biography Family background Both sides of Spinoza’s family were originally Sephardic Jews from Iberia. His immediate family immigrated to Amsterdam, arriving in the early seventeenth century, where they could practice their religion without persecution by the Portuguese Inquisition. The family in Portugal were New Christian forced converts (conversos) to Christianity. In Portugal in the early sixteenth century, the crown initially looked the other way as outwardly Catholic New Christians practiced Judaism in private. The Portuguese Inquisition was not even established until 1536. As the Inquisition increasingly cracked down, more New Christians continued practicing Judaism in secrecy. A legacy of the era was that many in Spinoza's family had both Christian and Jewish names. Spinoza’s father Michael, also known by his Christian name Gabriel Álvares d’Espinosa, was a successful merchant in Amsterdam, dealing internationally in various commodities, including dried figs from Morocco and textiles from France. Spinoza’s paternal grandfather, Isaac d’Espinosa (alias Pedro Rodrigues d’Espinosa) (d. 1627) had emigrated from Portugal to Nantes, a major trading hub with a New Christian community practicing Judaism in secret; he died, living as a Jew, in Rotterdam. Spinoza’s great uncle Abraham d’Espinosa (d. 1637) had provided capital for Michael’s business. Michael married his cousin Raquel d’Espinosa, daughter of his uncle Abraham d’Espinosa, a pattern fairly common in the Jewish merchant community, keeping commercial and religious ties strong. When Michael’s wife died in 1627, he married again to Hannah Deborah, and had five children, including Spinoza. Spinoza's maternal grandfather was Henrique Garces, known in the Jewish community as Baruch Senior (d. 1619), for whom Spinoza was named. Baruch Senior’s parents, Francisco Bentalhado and Violante Gomes, were from Porto, the northern port of Portugal. In At some point Spinoza’s maternal grandfather Henrique Garces moved to the trading hub of Antwerp and was one of 75 male heads of household of the “Portuguese nation” (a term with the strong connotation of being Jews). Spinoza’s grandfather Henrique married a cousin of the Bentalhado family, Maria Nunes, called Miriam, in 1605 in Amsterdam. Miriam’s parents, Duarte Fernandes (Joshua Habilho or Gabilho, 1541-ca. 1623) and his wife Isabel Nunes were Henrique’s uncle and aunt by marriage and moved to Amsterdam. Spinoza’s maternal great grandfather Duarte Fernandez was a wealthy merchant who had fled Portugal, briefly lived in Venice, a center of Sephardic settlement, and then moved to the Netherlands. Spinoza’s maternal grandmother Miriam was born and raised in Lisbon, where she was baptized, then taken as a child to Venice, where the family lived as Jews. Dealing in sugar from Brazil and Baltic grain, Duarte emerged as a major leader of the nascent Jewish community in Amsterdam. Henrique Garces’s marriage into this wealthy branch of the family increased his involvement in the Jewish community in Amsterdam, but regularly took him on business to Antwerp, where he had to be circumspect about his religious practice. Spinoza’s maternal grandfather did not evince as strong a commitment to formal Judaism as his uncle/father-in-law. Spinoza’s father Michael married his cousin Raquel d'Espinosa, giving him access to his uncle/father-in-law’s commercial network and capital, but she died without the couple having offspring. Despite Abraham having sons who might have been his commercial heirs, he maintained close relations with Michael, his nephew and son-in-law. After being widowed, Michael then married Hannah Deborah, who brought a dowry to the marriage. This marriage proved fruitful, with five children who survived to adulthood. The first-born was Miriam, followed by Isaac (1631-49), named after his paternal grandfather, Isaac Senior. Isaac d'Espinosa was expected to take over as head of family and its commercial enterprise. Spinoza was born in 1632 and named as per tradition for his maternal grandfather, Baruch Senior. Spinoza’s younger brother Gabriel (Abraham) was born in 1634, followed by another sister, Rebecca (Ribca). Spinoza’s sister Miriam married Samuel de Caceres, and the couple had one child, with Miriam dying shortly after giving birth. Following Jewish tradition, the widower Samuel married his former sister-in-law Rebecca. Spinoza was related in a complicated way with the highly controversial figure in the Amsterdam Jewish community, Uriel da Costa (1585-1640), through his mother’s family in Porto. DaCosta was twice sanctioned by rabbinic authorities, and committed suicide in 1640, more than a decade before Spinoza's birth. He might not have known of the scandalous family connection until he was an adolescent. School days Baruch Espinosa was born on 24 November 1632 in the Jodenbuurt in Amsterdam, Netherlands. He was the third child and second son of Michael de Espinoza, a successful, although not enormously wealthy, Portuguese Sephardic Jewish merchant in Amsterdam, prominent in the community. His mother, Hannah Déborah, Michael's second wife, died when Baruch was only six years old and Michael remarried to give his five children a mother figure; the third marriage was childless so that Spinoza and his siblings had no half- or step-siblings. The family spoke Portuguese, as did other Sephardim. He studied Hebrew at school and heard it Jewish liturgy; he knew Dutch, which he likely learned informally. He learned Latin only later as a young man. His name in contemporary documents before his 1656 expulsion from the Jewish community is given as the Portuguese "Bento"; his Hebrew name "Baruch" was used in the religious context. Following his expulsion at age 23, he used the Latinized version of his name, "Benedictus de Spinoza." Spinoza had a traditional upbringing for a Jewish boy, attending a local religious school, the Keter Torah yeshiva of the Amsterdam Talmud Torah congregation headed by the learned and traditional senior Rabbi Saul Levi Morteira. Teachers also included the less traditional Rabbi Manasseh ben Israel. Since Spinoza never reached the level of advanced study of the Torah, the senior rabbis were unlikely to have had Spinoza as their pupil. Spinoza's end of schooling was due the unexpected death of his elder brother Isaac, who had been actively involved in the family business. The family business and intellectual explorations When Spinoza's father, Michael, died in 1654, Spinoza had been actively involved in the running of the family business. As with other merchants in Amsterdam, the Spinozas' business was affected by the First Anglo-Dutch War 1652-1654, but also some commercial deals that soured. The business was in severe difficulty. Spinoza was just 21 when his father died, in Dutch law a legal minor until age 25. Nonetheless, he and his younger brother Gabriel (Abraham) formed a business partnership, attempting to continue the family business, including collecting unpaid debts owed by merchants to their father's estate. Although Spinoza duly recited Kaddish, the Jewish prayer of mourning, for eleven months as required by Jewish law, there is evidence that his relations with his father had been chilly. Michael had absorbed the dowry of Spinoza's mother as regular capital for his business, rather than keeping it separate for her children after her death. As such, the money was at risk for collection by Michael's many creditors. Spinoza had continued to support the synagogue financially and attend services. When his sister Rebekah disputed his inheritance seeking it for herself, on principle he sued her to seek a court judgment, he won the case, but then renounced claim to the court's judgment in his favor and assigned his inheritance to her. In March 1656, Spinoza filed suit with the Amsterdam municipal authorities to be declared an orphan, since he was still a legal minor. He sought relief through Dutch law, not through judgment by Jewish authorities, from whom he had become increasingly estranged, but not openly as yet. He won the civil lawsuit which allowed him to inherit his mother's estate without it being subject to his father's creditors and devote himself chiefly to the study of philosophy, especially the system expounded by Descartes, and to optics. At some point between 1654 and 1658, Spinoza began to study Latin with Franciscus van den Enden. Van den Enden was a former Jesuit who was a political radical, and likely introduced Spinoza to scholastic and modern philosophy, including that of Descartes. Spinoza adopted the Latin name Benedictus de Spinoza, began boarding with Van den Enden, and began teaching in his school. During this period Spinoza also became acquainted with the Collegiants, an anti-clerical sect of Remonstrants with tendencies towards rationalism, and with the liberal faction among the Mennonites who had existed for a century but were close to the Remonstrants. Many of his friends belonged to dissident Christian groups which met regularly as discussion groups and which typically rejected the authority of established churches as well as traditional dogmas. In the second half on the 1650s and the first half of the 1660s Spinoza became acquainted with several persons who would themselves emerge as unorthodox thinkers: this group, known as the Spinoza Circle, included , , Lodewijk Meyer, Johannes Bouwmeester and Adriaen Koerbagh. Expulsion from the Jewish community Spinoza did not openly break with Jewish authorities until after his father's death in 1654. He challenged the prevailing dogmas of Judaism, and particularly the insistence on non-Mosaic authorship of the Pentateuch, was not sudden; rather, it appears to have been the result of a lengthy internal struggle as well as a degree of filial piety. Nevertheless, after he was branded as a heretic, Spinoza's clashes with authority became more pronounced. He was later attacked on the steps of the synagogue by a knife-wielding assailant shouting "Heretic!" He was apparently quite shaken by this attack and for years kept (and wore) his torn cloak, unmended, as a reminder. On 27 July 1656, the Talmud Torah congregation of Amsterdam issued a writ of herem (Hebrew: , a kind of ban, shunning, ostracism, expulsion, or excommunication) against the 23-year-old Spinoza. The Talmud Torah congregation issued censures routinely, on matters great and small, so such an edict was not unusual. However, language of Spinoza's censure is unusually harsh, however, and does not appear in any other censure known to have been issued by the Portuguese Jewish community in Amsterdam. The exact reason for expelling Spinoza is not stated. The censure refers only to the "abominable heresies [horrendas heregias] that he practised and taught", to his "monstrous deeds", and to the testimony of witnesses "in the presence of the said Espinoza". There is no record of such testimony, but there appear to have been several likely reasons for the issuance of the censure. Spinoza began publicly expressing radical religious views that were highly controversial. Spinoza biographer Steven Nadler wrote: "No doubt he was giving utterance to just those ideas that would soon appear in his philosophical treatises. In those works, Spinoza denies the immortality of the soul; strongly rejects the notion of a providential God—the God of Abraham, Isaac and Jacob; and claims that the [Mosiac] Law was neither literally given by God nor any longer binding on Jews." The Amsterdam Jewish community was largely composed of Spanish and Portuguese conversos, "New Christians", who had respectively migrated from Spain via Portugal to escape the Spanish Inquisition and Portuguese conversos, following the establishment of the Portuguese Inquisition, with their children and grandchildren. Amsterdam was tolerant of religious diversity so long as it was practiced discreetly, Jews were not legally confined to a ghetto, and the city presented economic opportunities for those willing to move. This community must have been concerned to protect its reputation from any association with Spinoza lest his controversial views provide the basis for their own possible persecution or expulsion. There is little evidence that the Amsterdam municipal authorities were directly involved in Spinoza's censure itself. But "in 1619, the town council expressly ordered [the Portuguese Jewish community] to regulate their conduct and ensure that the members of the community kept to a strict observance of Jewish law." Other evidence makes it clear that the danger of upsetting the civil authorities was never far from mind, such as bans adopted by the synagogue on public wedding or funeral processions and on discussing religious matters with Christians, lest such activity might "disturb the liberty we enjoy". Thus, the issuance of Spinoza's censure was almost certainly, in part, an exercise in self-censorship by the Portuguese Jewish community in Amsterdam. It appears likely that Spinoza had already taken the initiative to separate himself from the Talmud Torah congregation and was vocally expressing his hostility to Judaism itself, also through his philosophical works, such as the Part I of Ethics. He had probably stopped attending services at the synagogue, either after the lawsuit with his sister or after the knife attack on its steps. He might already have been voicing the view expressed later in his Theological-Political Treatise that the civil authorities should suppress Judaism as harmful to the Jews themselves. Either for financial or other reasons, he had in any case effectively stopped contributing to the synagogue by March 1656. He had also committed the "monstrous deed", contrary to the regulations of the synagogue and the views of some rabbinical authorities (including Maimonides), of filing suit in a civil court rather than with the synagogue authorities—to renounce his father's heritage, no less. Upon being notified of the issuance of the censure, he is reported to have said: "Very well; this does not force me to do anything that I would not have done of my own accord, had I not been afraid of a scandal." Thus, unlike most of the censure issued routinely by the Amsterdam congregation to discipline its members, the censure issued against Spinoza did not lead to repentance and so was never withdrawn. After the censure, Spinoza is said to have addressed an Apologia (defense), written in Spanish, to the elders of the synagogue, "in which he defended his views as orthodox, and condemned the rabbis for accusing him of 'horrible practices and other enormities' merely because he had neglected ceremonial observances". This apologia does not survive, but some of its contents may later have been included in his Theological-Political Treatise. Spinoza's expulsion from the Jewish community did not lead to his conversion to Christianity. Spinoza used the Latinized name Benedictus de Spinoza and maintained a close association with the Collegiants (a liberal Protestant sect of Remonstrants) and Quakers, even moved to a town near the Collegiants' headquarters, and was buried at the Protestant Church, Nieuwe Kerk, The Hague, since burial was a sectarian matter and he was ineligible to be buried in the Jewish cemetery. There is no evidence he maintained any sense of Jewish identity. "Spinoza did not envision secular Judaism. To be a secular and assimilated Jew is, in his view, nonsense." Spinoza scholar Yirmiyahu Yovel raises the question of whether or not Spinoza could be categorized as the first "secular Jew" since he was still regarded as a Jew although he did not adhere to Jewish law or belong to the Jewish community. Yovel writes that Spinoza "exemplifies the situation of the modern Jew—secular, assimilationist, or national—without himself falling neatly into any of these categories. Countless Jews in the coming centuries were to find themselves in a similar predicament." Career as a philosopher Spinoza spent his remaining 22 years writing and studying as a private scholar, initially teaching in the school of his Latin tutor, Franciscus Van den Enden, with whom he boarded for a time, and later upon leaving Amsterdam, earning a living as a lens grinder. He also received some financial assistance from supporters of his intellectual stance. After the herem, the Amsterdam municipal authorities expelled Spinoza from Amsterdam, "responding to the appeals of the rabbis, and also of the Calvinist clergy, who had been vicariously offended by the existence of a free thinker in the synagogue". He spent a brief time in or near the village of Ouderkerk aan de Amstel, but returned soon afterwards to Amsterdam and lived there quietly for several years, giving private philosophy lessons and grinding lenses, before leaving the city in 1660 or 1661. During this time in Amsterdam, Spinoza wrote his Short Treatise on God, Man, and His Well-Being, which he never published in his lifetime—assuming with good reason that it might get suppressed. Two Dutch translations of it survive, discovered about 1810. In 1660 or 1661, Spinoza moved from Amsterdam to Rijnsburg (near Leiden), the center of Dutch Remonstrants known as the Collegiants. In Rijnsburg, he began work on his Descartes' "Principles of Philosophy" as well as on his masterpiece, the Ethics. In 1663, he returned briefly to Amsterdam, where he finished and published Descartes' "Principles of Philosophy", the only work published in his lifetime under his own name, and then moved the same year to Voorburg. In Voorburg, Spinoza continued work on his magnum opus, eventually entitled Ethics, and corresponded with scientists, philosophers, and theologians throughout Europe. He published in Latin, anonymously, and with false printer information Theological-Political Treatise (TTP) in 1670, in defense of secular and constitutional government, and in support of Jan de Witt, the Grand Pensionary of Holland, against the Stadtholder, the Prince of Orange. Leibniz visited Spinoza and claimed that Spinoza's life was in danger when supporters of the Prince of Orange murdered de Witt in 1672. While the TTP published anonymously, the work did not long remain so, and de Witt's enemies characterized it as "forged in Hell by a renegade Jew and the Devil, and issued with the knowledge of Jan de Witt". It was condemned in 1673 by the Synod of the Dutch Reformed Church and formally banned in 1674. In 1670, Spinoza moved to The Hague where he lived on a small pension from Jan de Witt and a small annuity from the brother of his dead friend, Simon de Vries. He worked on the Ethics, wrote an unfinished Hebrew grammar, began his Political Treatise (TP), left unfinished at his death, wrote two scientific essays ("On the Rainbow" and "On the Calculation of Chances"), and began a Dutch translation of the Bible (which he later destroyed). Spinoza was offered the chair of philosophy at the University of Heidelberg, but he refused it, perhaps because of the possibility that it might in some way curb his freedom of thought. Spinoza also corresponded with Peter Serrarius, a radical Protestant and millenarian merchant. Serrarius was a patron to Spinoza after Spinoza was expelled from the Jewish community. He acted as an intermediary for Spinoza's correspondence, sending and receiving letters of the philosopher to and from third parties. Spinoza and Serrarius maintained their relationship until Serrarius' death in 1669. By the beginning of the 1660s, Spinoza's name became more widely known. The Secretary of the British Royal Society Henry Oldenburg paid him visits and became a correspondent with Spinoza for the rest of his life. In 1676, Leibniz came to the Hague to discuss the unpublished Ethics, Spinoza's principal philosophical work, parts of which apparently circulates in manuscript form. Lens-grinding and optics Spinoza earned a modest living from lens-grinding and instrument making, yet he was involved in important optical investigations of the day while living in Voorburg, through correspondence and friendships with scientist Christiaan Huygens and mathematician Johannes Hudde, including debate over microscope design with Huygens, favouring small objectives and collaborating on calculations for a prospective focal length telescope which would have been one of the largest in Europe at the time. He was known for making not just lenses but also telescopes and microscopes. The quality of Spinoza's lenses was much praised by Christiaan Huygens, among others. In fact, his technique and instruments were so esteemed that Constantijn Huygens ground a "clear and bright" telescope lens with focal length of in 1687 from one of Spinoza's grinding dishes, ten years after his death. He was said by anatomist Theodor Kerckring to have produced an "excellent" microscope, the quality of which was the foundation of Kerckring's anatomy claims. During his time as a lens and instrument maker, he was also supported by small but regular donations from close friends. Death and burial Spinoza's health began to fail in 1676, dying in The Hague on 21 February 1677 at the age of 44, attended by a physician friend, Georg Herman Schuller. Although he had been ill with some form of lung affliction, described as "ex phthisi [from consumption]", perhaps complicated by silicosis brought on by grinding glass lenses, his death on that particular day was unexpected by himself or his landlord and landlady with whom he lived, and he died without leaving a will. His personal belongings and papers, most importantly his unpublished manuscripts, were stored in a cabinet attached to his writing desk, and were taken away for safekeeping from seizure by those wishing to suppress his writings. They do not appear in the inventory of his possessions at death. There were assertions that he had repented his philosophical stances on his deathbed, but all credible evidence points to his dying unrepentant and in tranquility. The first biography of Spinoza by Lutheran preacher Johannes Colerus (1647-1707), was prompted to investigate Spinoza's last days. Spinoza was buried in the Nieuwe Kerk (New Church) on the Spui four days after his death, on 25 February, inside the church, with six others in the same vault. At the time there was no memorial plaque for Spinoza. In the 18th century, the vault was emptied, and the remains disposed of, with the "remnants scattered over the earth of the churchyard." The memorial plaque visitors now see is outside, where some of his remains are part of the churchyard's soil. Writings Spinoza published little in his lifetime and most of his formal writings were in Latin, which would have reached only a small number of readers. His supporters published his works posthumously, in Latin and in Dutch, with other translations to European languages following. A descriptive bibliography has been published that contextualizes all aspects of the publication history of Spinoza's writings from manuscript to print. The reaction to the anonymously published work, Theologico-Political Treatise (TTP)(1670), was extremely unfavorable. Spinoza abstained from publishing further, but his writings circulated among his supporters during his lifetime. Wary and independent, he wore a signet ring which he used to mark his letters and which was engraved with the word caute (Latin for "cautiously") underneath a rose, itself a symbol of secrecy. The Ethics and all other works, apart from the Descartes' Principles of Philosophy and the Theologico-Political Treatise, were published after his 1677 death. The Opera Posthuma was edited by his friends in secrecy to prevent confiscation and destruction of manuscripts. The Ethics contains many still-unresolved obscurities and is written with a forbidding mathematical structure modeled on Euclid's geometry and has been described as a "superbly cryptic masterwork".

Correspondence Few letters are extant for such an important intellectual figure and none before 1661. Spinoza engaged in correspondence from December 1664 to June 1665 with Willem van Blijenbergh, an amateur Calvinist theologian, who questioned Spinoza on the definition of evil. Later in 1665, Spinoza notified Oldenburg that he had started to work on a new book, the Theologico-Political Treatise, published in 1670. Leibniz disagreed harshly with Spinoza in his own manuscript "Refutation of Spinoza", but he is also known to have met with Spinoza on at least one occasion (as mentioned above), and his own work bears some striking resemblances to specific important parts of Spinoza's philosophy (see: Monadology). In a letter, written in December 1675 and sent to Albert Burgh, who wanted to defend Catholicism, Spinoza clearly explained his view of both Catholicism and Islam. He stated that both religions are made "to deceive the people and to constrain the minds of men". He also states that Islam far surpasses Catholicism in doing so. The Tractatus de Deo, Homine, ejusque Felicitate (Treatise on God, man and his happiness) was one of the last Spinoza's works to be published, between 1851 and 1862. Philosophy Spinoza's philosophy is explicated in his two major publications originally written in Latin, the Tratacus Theologico-Politicus (TTP) (1670) and the Ethics, published posthumously in Latin and Dutch. Tractacus Theologico-Politicus Despite its being published in Latin rather than a vernacular language, this 1670 treatise published in Spinoza's lifetime caused an uproar described as "one of the most significant events in European intellectual history." Ethics The Ethics has been associated with that of Leibniz and René Descartes as part of the rationalist school of thought, which includes the assumption that ideas correspond to reality perfectly, in the same way that mathematics is supposed to be an exact representation of the world. The writings of René Descartes have been described as "Spinoza's starting point". Spinoza's first publication was his 1663 geometric exposition of proofs using Euclid's model with definitions and axioms of Descartes' Principles of Philosophy. Following Descartes, Spinoza aimed to understand truth through logical deductions from 'clear and distinct ideas', a process which always begins from the 'self-evident truths' of axioms. Metaphysics Spinoza's metaphysics consists of one thing, substance, and its modifications (modes). Early in The Ethics Spinoza argues that there is only one substance, which is absolutely infinite, self-caused, and eternal. He calls this substance "God", or "Nature". In fact, he takes these two terms to be synonymous (in the Latin the phrase he uses is "Deus sive Natura"). For Spinoza the whole of the natural universe is made of one substance, God, or, what is the same, Nature, and its modifications (modes). Substance, attributes, and modes Following Maimonides, Spinoza defined substance as "that which is in itself and is conceived through itself", meaning that it can be understood without any reference to anything external. Being conceptually independent also means that the same thing is ontologically independent, depending on nothing else for its existence and being the 'cause of itself' (causa sui). A mode is something which cannot exist independently but rather must do so as part of something else on which it depends, including properties (for example colour), relations (such as size) and individual things. Modes can be further divided into 'finite' and 'infinite' ones, with the latter being evident in every finite mode (he gives the examples of "motion" and "rest"). The traditional understanding of an attribute in philosophy is similar to Spinoza's modes, though he uses that word differently. To him, an attribute is "that which the intellect perceives as constituting the essence of substance", and there are possibly an infinite number of them. It is the essential nature which is "attributed" to reality by intellect. Spinoza defined God as "a substance consisting of infinite attributes, each of which expresses eternal and infinite essence", and since "no cause or reason" can prevent such a being from existing, it therefore must exist. This is a form of the ontological argument, which is claimed to prove the existence of God, but Spinoza went further in stating that it showed that only God exists. Accordingly, he stated that "Whatever is, is in God, and nothing can exist or be conceived without God". This means that God is identical with the universe, an idea which he encapsulated in the phrase "Deus sive Natura" ('God or Nature'), which has been interpreted by some as atheism or pantheism. God can be known either through the attribute of extension or the attribute of thought. Thought and extension represent giving complete accounts of the world in mental or physical terms. To this end, he says that "the mind and the body are one and the same thing, which is conceived now under the attribute of thought, now under the attribute of extension". After stating his proof for God's existence, Spinoza addresses who "God" is. Spinoza believed that God is "the sum of the natural and physical laws of the universe and certainly not an individual entity or creator". Spinoza attempts to prove that God is just the substance of the universe by first stating that substances do not share attributes or essences and then demonstrating that God is a "substance" with an infinite number of attributes, thus the attributes possessed by any other substances must also be possessed by God. Therefore, God is just the sum of all the substances of the universe. God is the only substance in the universe, and everything is a part of God. This view was described by Charles Hartshorne as Classical Pantheism. Spinoza argues that "things could not have been produced by God in any other way or in any other order than is the case". Therefore, concepts such as 'freedom' and 'chance' have little meaning. This picture of Spinoza's determinism is illuminated in Ethics: "the infant believes that it is by free will that it seeks the breast; the angry boy believes that by free will he wishes vengeance; the timid man thinks it is with free will he seeks flight; the drunkard believes that by a free command of his mind he speaks the things which when sober he wishes he had left unsaid. … All believe that they speak by a free command of the mind, whilst, in truth, they have no power to restrain the impulse which they have to speak." In his letter to G. H. Schuller (Letter 58), he wrote: "men are conscious of their desire and unaware of the causes by which [their desires] are determined." He also held that knowledge of true causes of passive emotion can transform it into an active emotion, thus anticipating one of the key ideas of Sigmund Freud's psychoanalysis. According to Professor Eric Schliesser, Spinoza was skeptical regarding the possibility of knowledge of nature and as a consequence at odds with scientists like Galileo and Huygens. Causality Though the principle of sufficient reason is most commonly associated with Gottfried Leibniz, it is arguably found in its strongest form in Spinoza's philosophy. Within the context of Spinoza's philosophical system, the principle can be understood to unify causation and explanation. What this means is that for Spinoza, questions regarding the reason why a given phenomenon is the way it is (or exists) are always answerable, and are always answerable in terms of the relevant cause(s). This constitutes a rejection of teleological, or final causation, except possibly in a more restricted sense for human beings. Given this, Spinoza's views regarding causality and modality begin to make much more sense. Spinoza has also been described as an "Epicurean materialist", specifically in reference to his opposition to Cartesian mind-body dualism. This view was held by Epicureans before him, as they believed that atoms with their probabilistic paths were the only substance that existed fundamentally. Spinoza, however, deviated significantly from Epicureans by adhering to strict determinism, much like the Stoics before him, in contrast to the Epicurean belief in the probabilistic path of atoms, which is more in line with contemporary thought on quantum mechanics. The emotions One thing which seems, on the surface, to distinguish Spinoza's view of the emotions from both Descartes' and Hume's pictures of them is that he takes the emotions to be cognitive in some important respect. Jonathan Bennett claims that "Spinoza mainly saw emotions as caused by cognitions. [However] he did not say this clearly enough and sometimes lost sight of it entirely." Spinoza provides several demonstrations which purport to show truths about how human emotions work. The picture presented is, according to Bennett, "unflattering, coloured as it is by universal egoism". Ethical philosophy Spinoza's notion of blessedness figures centrally in his ethical philosophy. Blessedness (or salvation or freedom), Spinoza thinks, And this means, as Jonathan Bennett explains, that "Spinoza wants "blessedness" to stand for the most elevated and desirable state one could possibly be in." Here, understanding what is meant by 'most elevated and desirable state' requires understanding Spinoza's notion of conatus (read: striving, but not necessarily with any teleological baggage) and that "perfection" refers not to (moral) value, but to completeness. Given that individuals are identified as mere modifications of the infinite Substance, it follows that no individual can ever be fully complete, i.e., perfect, or blessed. Absolute perfection, is, as noted above, reserved solely for Substance. Nevertheless, mere modes can attain a lesser form of blessedness, namely, that of pure understanding of oneself as one really is, i.e., as a definite modification of Substance in a certain set of relationships with everything else in the universe. That this is what Spinoza has in mind can be seen at the end of the Ethics, in E5P24 and E5P25, wherein Spinoza makes two final key moves, unifying the metaphysical, epistemological, and ethical propositions he has developed over the course of the work. In E5P24, he links the understanding of particular things to the understanding of God, or Substance; in E5P25, the conatus of the mind is linked to the third kind of knowledge (Intuition). From here, it is a short step to the connection of Blessedness with the amor dei intellectualis ("intellectual love of God"). Legacy Pantheism controversy Spinoza was considered to be an atheist because he used the word "God" [Deus] to signify a concept that was different from that of traditional Judeo–Christian monotheism. "Spinoza expressly denies personality and consciousness to God; he has neither intelligence, feeling, nor will; he does not act according to purpose, but everything follows necessarily from his nature, according to law...." Thus, Spinoza's cool, indifferent God differs from the concept of an anthropomorphic, fatherly God who cares about humanity. In 1785, Friedrich Heinrich Jacobi published a condemnation of Spinoza's pantheism, after Gotthold Lessing was thought to have confessed on his deathbed to being a "Spinozist", which was the equivalent in his time of being called an atheist. Jacobi claimed that Spinoza's doctrine was pure materialism, because all Nature and God are said to be nothing but extended substance. This, for Jacobi, was the result of Enlightenment rationalism and it would finally end in absolute atheism. Moses Mendelssohn disagreed with Jacobi, saying that there is no actual difference between theism and pantheism. The issue became a major intellectual and religious concern for European civilization at the time. The attraction of Spinoza's philosophy to late 18th-century Europeans was that it provided an alternative to materialism, atheism, and deism. Three of Spinoza's ideas strongly appealed to them: the unity of all that exists; the regularity of all that happens; the identity of spirit and nature. By 1879, Spinoza's pantheism was praised by many, but was considered by some to be alarming and dangerously inimical. Spinoza's "God or Nature" (Deus sive Natura) provided a living, natural God, in contrast to Isaac Newton's first cause argument and the dead mechanism of Julien Offray de La Mettrie's (1709–1751) work, Man a Machine (). Coleridge and Shelley saw in Spinoza's philosophy a religion of nature. Novalis called him the "God-intoxicated man". Spinoza inspired the poet Shelley to write his essay "The Necessity of Atheism". It is a widespread belief that Spinoza equated God with the material universe. He has therefore been called the "prophet" and "prince" and most eminent expounder of pantheism. More specifically, in a letter to Henry Oldenburg he states, "as to the view of certain people that I identify God with Nature (taken as a kind of mass or corporeal matter), they are quite mistaken". For Spinoza, the universe (cosmos) is a mode under two attributes of Thought and Extension. God has infinitely many other attributes which are not present in the world. According to German philosopher Karl Jaspers (1883–1969), when Spinoza wrote (Latin for 'God or Nature'), Spinoza meant God was (nature doing what nature does; literally, 'nature naturing'), not (nature already created; literally, 'nature natured'). Jaspers believed that Spinoza, in his philosophical system, did not mean to say that God and Nature are interchangeable terms, but rather that God's transcendence was attested by his infinitely many attributes, and that two attributes known by humans, namely Thought and Extension, signified God's immanence. Even God under the attributes of thought and extension cannot be identified strictly with our world. That world is of course "divisible"; it has parts. But Spinoza said, "no attribute of a substance can be truly conceived from which it follows that the substance can be divided", meaning that one cannot conceive an attribute in a way that leads to division of substance. He also said, "a substance which is absolutely infinite is indivisible" (Ethics, Part I, Propositions 12 and 13). Following this logic, our world should be considered as a mode under two attributes of thought and extension. Therefore, according to Jaspers, the pantheist formula "One and All" would apply to Spinoza only if the "One" preserves its transcendence and the "All" were not interpreted as the totality of finite things. Martial Guéroult (1891–1976) suggested the term "panentheism", rather than "pantheism" to describe Spinoza's view of the relation between God and the world. The world is not God, but it is, in a strong sense, "in" God. Not only do finite things have God as their cause; they cannot be conceived without God. However, American panentheist philosopher Charles Hartshorne (1897–2000) insisted on the term Classical Pantheism to describe Spinoza's view. According to the Stanford Encyclopedia of Philosophy, Spinoza's God is an "infinite intellect" (Ethics 2p11c) — all knowing (2p3), and capable of loving both himself—and us, insofar as we are part of his perfection (5p35c). And if the mark of a personal being is that it is one towards which we can entertain personal attitudes, then we should note too that Spinoza recommends amor intellectualis dei (the intellectual love of God) as the supreme good for man (5p33). However, the matter is complex. Spinoza's God does not have free will (1p32c1), he does not have purposes or intentions (1 appendix), and Spinoza insists that "neither intellect nor will pertain to the nature of God" (1p17s1). Moreover, while we may love God, we need to remember that God is really not the kind of being who could ever love us back. "He who loves God cannot strive that God should love him in return", says Spinoza (5p19). Steven Nadler suggests that settling the question of Spinoza's atheism or pantheism depends on an analysis of attitudes. If pantheism is associated with religiosity, then Spinoza is not a pantheist, since Spinoza believes that the proper stance to take towards God is not one of reverence or religious awe, but instead one of objective study and reason, since taking the religious stance would leave one open to the possibility of error and superstition. In modern and contemporary philosophy Hegel said, "The fact is that Spinoza is made a testing-point in modern philosophy, so that it may really be said: You are either a Spinozist or not a philosopher at all." Similarities between Spinoza's philosophy and Eastern philosophical traditions have been discussed by many authors. The 19th-century German Sanskritist Theodor Goldstücker was one of the early figures to notice the similarities between Spinoza's religious conceptions and the Vedanta tradition of India, writing that Spinoza's thought was "... so exact a representation of the ideas of the Vedanta, that we might have suspected its founder to have borrowed the fundamental principles of his system from the Hindus, did his biography not satisfy us that he was wholly unacquainted with their doctrines..." Max Müller also noted the striking similarities between Vedanta and the system of Spinoza, equating the Brahman in Vedanta to Spinoza's 'Substantia.' When George Santayana graduated from college, he published an essay, "The Ethical Doctrine of Spinoza", in The Harvard Monthly. Later, he wrote an introduction to Spinoza's Ethics and "De Intellectus Emendatione". In 1932, Santayana was invited to present an essay (published as "Ultimate Religion") at a meeting at The Hague celebrating the tricentennial of Spinoza's birth. In Santayana's autobiography, he characterized Spinoza as his "master and model" in understanding the naturalistic basis of morality. Philosopher Ludwig Wittgenstein evoked Spinoza with the title (suggested to him by G. E. Moore) of the English translation of his first definitive philosophical work, Tractatus Logico-Philosophicus, an allusion to Spinoza's Tractatus Theologico-Politicus. Elsewhere, Wittgenstein deliberately borrowed the expression sub specie aeternitatis from Spinoza (Notebooks, 1914–16, p. 83). The structure of his Tractatus Logico-Philosophicus does have some structural affinities with Spinoza's Ethics (though, admittedly, not with the Spinoza's Tractatus) in erecting complex philosophical arguments upon basic logical assertions and principles. Furthermore, in propositions 6.4311 and 6.45 he alludes to a Spinozian understanding of eternity and interpretation of the religious concept of eternal life, stating, "If by eternity is understood not eternal temporal duration, but timelessness, then he lives eternally who lives in the present." (6.4311) "The contemplation of the world sub specie aeterni is its contemplation as a limited whole." (6.45) Spinoza's philosophy played an important role in the development of post-war French philosophy. Many of these philosophers "used Spinoza to erect a bulwark against the nominally irrationalist tendencies of phenomenology", which was associated with the dominance of Hegel, Martin Heidegger, and Edmund Husserl in France at that time. Louis Althusser, as well as his colleagues such as Étienne Balibar, saw in Spinoza a philosophy which could lead Marxism out of what they considered to be flaws in its original formulation, particularly its reliance upon Hegel's conception of the dialectic, as well as Spinoza's concept of immanent causality. Antonio Negri, in exile in France for much of this period, also wrote a number of books on Spinoza, most notably The Savage Anomaly (1981) in his own reconfiguration of Italian Autonomia Operaia. Other notable French scholars of Spinoza in this period included Alexandre Matheron, Martial Gueroult, André Tosel, and Pierre Macherey, the last of whom published a widely read and influential five-volume commentary on Spinoza's Ethics, which has been described as "a monument of Spinoza commentary". His philosophical accomplishments and moral character prompted Gilles Deleuze in his doctoral thesis (1968) to name him "the prince of philosophers". Deleuze's interpretation of Spinoza's philosophy was highly influential among French philosophers, especially in restoring to prominence the political dimension of Spinoza's thought. Deleuze published two books on Spinoza and gave numerous lectures on Spinoza in his capacity as a professor at the University of Paris VIII. His own work was deeply influenced by Spinoza's philosophy, particularly the concepts of immanence and univocity. Marilena de Souza Chaui described Deleuze's Expressionism in Philosophy (1968) as a "revolutionary work for its discovery of expression as a central concept in Spinoza's philosophy." Albert Einstein named Spinoza as the philosopher who exerted the most influence on his world view (Weltanschauung). Spinoza equated God (infinite substance) with Nature, consistent with Einstein's belief in an impersonal deity. In 1929, Einstein was asked in a telegram by Rabbi Herbert S. Goldstein whether he believed in God. Einstein responded by telegram: "I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with the fates and actions of human beings." Leo Strauss dedicated his first book, Spinoza's Critique of Religion, to an examination of the latter's ideas. In the book, Strauss identified Spinoza as part of the tradition of Enlightenment rationalism that eventually produced Modernity. Moreover, he identifies Spinoza and his works as the beginning of Jewish Modernity. More recently Jonathan Israel argued that, from 1650 to 1750, Spinoza was "the chief challenger of the fundamentals of revealed religion, received ideas, tradition, morality, and what was everywhere regarded, in absolutist and non-absolutist states alike, as divinely constituted political authority." Spinoza is an important historical figure in the Netherlands, where his portrait was featured prominently on the Dutch 1000-guilder banknote, legal tender until the euro was introduced in 2002. The highest and most prestigious scientific award of the Netherlands is named the Spinozaprijs (Spinoza prize). Spinoza was included in a 50 theme canon that attempts to summarise the history of the Netherlands. In 2014 a copy of Spinoza's Tractatus Theologico-Politicus was presented to the Chair of the Dutch Parliament, and shares a shelf with the Bible and the Quran. Reconsideration of excommunication in modern times There has been a renewed debate in modern times about Spinoza's excommunication among Israeli politicians, rabbis and Jewish press, with many calling for the cherem to be reversed. Since such a cherem can only be rescinded by the congregation that issued it, and the chief rabbi of that community, Haham Pinchas Toledano, declined to do so, citing Spinoza's "preposterous ideas, where he was tearing apart the very fundamentals of our religion", the Amsterdam Jewish community organised a symposium in December 2015 to discuss lifting the cherem, inviting scholars from around the world to form an advisory committee at the meeting. However, the rabbi of the congregation ruled that it should hold, on the basis that he had no greater wisdom than his predecessors, and that Spinoza's views had not become less problematic over time. Memory and memorials Spinoza Lyceum, a high school in Amsterdam South was named after Spinoza. There is also a 3 metre tall marble statute of him on the grounds of the school carved by Hildo Krop. The Spinoza Havurah (a Humanistic Jewish community) was named in Spinoza's honor. The Spinoza Foundation Monument has a statute of Spinoza located in front of the Amsterdam City Hall (at Zwanenburgwal) It was created by Dutch sculptor Nicolas Dings and was erected in 2008.

Bird

Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. The study of birds is called ornithology. Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs. Likewise, birds are considered reptiles in the modern cladistic sense of the term, and their closest living relatives are the crocodilians. Birds are descendants of the primitive avialans (whose members include Archaeopteryx) which first appeared during the Late Jurassic. According to DNA evidence, modern birds (Neornithes) evolved in the Early to Late Cretaceous, and diversified dramatically around the time of the Cretaceous–Paleogene extinction event 66 mya, which killed off the pterosaurs and all non-avian dinosaurs. Many social species pass on knowledge across generations, which is considered a form of culture. Birds are social, communicating with visual signals, calls, and songs, and participating in such behaviours as cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of bird species are socially (but not necessarily sexually) monogamous, usually for one breeding season at a time, sometimes for years, and rarely for life. Other species have breeding systems that are polygynous (one male with many females) or, rarely, polyandrous (one female with many males). Birds produce offspring by laying eggs which are fertilised through sexual reproduction. They are usually laid in a nest and incubated by the parents. Most birds have an extended period of parental care after hatching. Many species of birds are economically important as food for human consumption and raw material in manufacturing, with domesticated and undomesticated birds being important sources of eggs, meat, and feathers. Songbirds, parrots, and other species are popular as pets. Guano (bird excrement) is harvested for use as a fertiliser. Birds figure throughout human culture. About 120 to 130 species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry. Evolution and classification The first classification of birds was developed by Francis Willughby and John Ray in their 1676 volume Ornithologiae. Carl Linnaeus modified that work in 1758 to devise the taxonomic classification system currently in use. Birds are categorised as the biological class Aves in Linnaean taxonomy. Phylogenetic taxonomy places Aves in the clade Theropoda. Definition Aves and a sister group, the order Crocodilia, contain the only living representatives of the reptile clade Archosauria. During the late 1990s, Aves was most commonly defined phylogenetically as all descendants of the most recent common ancestor of modern birds and Archaeopteryx lithographica. However, an earlier definition proposed by Jacques Gauthier gained wide currency in the 21st century, and is used by many scientists including adherents to the PhyloCode. Gauthier defined Aves to include only the crown group of the set of modern birds. This was done by excluding most groups known only from fossils, and assigning them, instead, to the broader group Avialae, in part to avoid the uncertainties about the placement of Archaeopteryx in relation to animals traditionally thought of as theropod dinosaurs. Gauthier and de Queiroz identified four different definitions for the same biological name "Aves", which is a problem. The authors proposed to reserve the term Aves only for the crown group consisting of the last common ancestor of all living birds and all of its descendants, which corresponds to meaning number 4 below. He assigned other names to the other groups. Aves can mean all archosaurs closer to birds than to crocodiles (alternately Avemetatarsalia) Aves can mean those advanced archosaurs with feathers (alternately Avifilopluma) Aves can mean those feathered dinosaurs that fly (alternately Avialae) Aves can mean the last common ancestor of all the currently living birds and all of its descendants (a "crown group", in this sense synonymous with Neornithes) Under the fourth definition Archaeopteryx, traditionally considered one of the earliest members of Aves, is removed from this group, becoming a non-avian dinosaur instead. These proposals have been adopted by many researchers in the field of palaeontology and bird evolution, though the exact definitions applied have been inconsistent. Avialae, initially proposed to replace the traditional fossil content of Aves, is often used synonymously with the vernacular term "bird" by these researchers. Most researchers define Avialae as branch-based clade, though definitions vary. Many authors have used a definition similar to "all theropods closer to birds than to Deinonychus", with Troodon being sometimes added as a second external specifier in case it is closer to birds than to Deinonychus. Avialae is also occasionally defined as an apomorphy-based clade (that is, one based on physical characteristics). Jacques Gauthier, who named Avialae in 1986, re-defined it in 2001 as all dinosaurs that possessed feathered wings used in flapping flight, and the birds that descended from them. Despite being currently one of the most widely used, the crown-group definition of Aves has been criticised by some researchers. Lee and Spencer (1997) argued that, contrary to what Gauthier defended, this definition would not increase the stability of the clade and the exact content of Aves will always be uncertain because any defined clade (either crown or not) will have few synapomorphies distinguishing it from its closest relatives. Their alternative definition is synonymous to Avifilopluma. Dinosaurs and the origin of birds Based on fossil and biological evidence, most scientists accept that birds are a specialised subgroup of theropod dinosaurs and, more specifically, members of Maniraptora, a group of theropods which includes dromaeosaurids and oviraptorosaurs, among others. As scientists have discovered more theropods closely related to birds, the previously clear distinction between non-birds and birds has become blurred. By the 2000s, discoveries in the Liaoning Province of northeast China, which demonstrated many small theropod feathered dinosaurs, contributed to this ambiguity. The consensus view in contemporary palaeontology is that the flying theropods, or avialans, are the closest relatives of the deinonychosaurs, which include dromaeosaurids and troodontids. Together, these form a group called Paraves. Some basal members of Deinonychosauria, such as Microraptor, have features which may have enabled them to glide or fly. The most basal deinonychosaurs were very small. This evidence raises the possibility that the ancestor of all paravians may have been arboreal, have been able to glide, or both. Unlike Archaeopteryx and the non-avialan feathered dinosaurs, who primarily ate meat, studies suggest that the first avialans were omnivores. The Late Jurassic Archaeopteryx is well known as one of the first transitional fossils to be found, and it provided support for the theory of evolution in the late 19th century. Archaeopteryx was the first fossil to display both clearly traditional reptilian characteristics—teeth, clawed fingers, and a long, lizard-like tail—as well as wings with flight feathers similar to those of modern birds. It is not considered a direct ancestor of birds, though it is possibly closely related to the true ancestor. Early evolution Over 40% of key traits found in modern birds evolved during the 60 million year transition from the earliest bird-line archosaurs to the first maniraptoromorphs, i.e. the first dinosaurs closer to living birds than to Tyrannosaurus rex. The loss of osteoderms otherwise common in archosaurs and acquisition of primitive feathers might have occurred early during this phase. After the appearance of Maniraptoromorpha, the next 40 million years marked a continuous reduction of body size and the accumulation of neotenic (juvenile-like) characteristics. Hypercarnivory became increasingly less common while braincases enlarged and forelimbs became longer. The integument evolved into complex, pennaceous feathers. The oldest known paravian (and probably the earliest avialan) fossils come from the Tiaojishan Formation of China, which has been dated to the late Jurassic period (Oxfordian stage), about 160 million years ago. The avialan species from this time period include Anchiornis huxleyi, Xiaotingia zhengi, and Aurornis xui. The well-known probable early avialan, Archaeopteryx, dates from slightly later Jurassic rocks (about 155 million years old) from Germany. Many of these early avialans shared unusual anatomical features that may be ancestral to modern birds but were later lost during bird evolution. These features include enlarged claws on the second toe which may have been held clear of the ground in life, and long feathers or "hind wings" covering the hind limbs and feet, which may have been used in aerial maneuvering. Avialans diversified into a wide variety of forms during the Cretaceous period. Many groups retained primitive characteristics, such as clawed wings and teeth, though the latter were lost independently in a number of avialan groups, including modern birds (Aves). Increasingly stiff tails (especially the outermost half) can be seen in the evolution of maniraptoromorphs, and this process culminated in the appearance of the pygostyle, an ossification of fused tail vertebrae. In the late Cretaceous, about 100 million years ago, the ancestors of all modern birds evolved a more open pelvis, allowing them to lay larger eggs compared to body size. Around 95 million years ago, they evolved a better sense of smell. A third stage of bird evolution starting with Ornithothoraces (the "bird-chested" avialans) can be associated with the refining of aerodynamics and flight capabilities, and the loss or co-ossification of several skeletal features. Particularly significant are the development of an enlarged, keeled sternum and the alula, and the loss of grasping hands. Early diversity of bird ancestors The first large, diverse lineage of short-tailed avialans to evolve were the Enantiornithes, or "opposite birds", so named because the construction of their shoulder bones was in reverse to that of modern birds. Enantiornithes occupied a wide array of ecological niches, from sand-probing shorebirds and fish-eaters to tree-dwelling forms and seed-eaters. While they were the dominant group of avialans during the Cretaceous period, enantiornithes became extinct along with many other dinosaur groups at the end of the Mesozoic era. Many species of the second major avialan lineage to diversify, the Euornithes (meaning "true birds", because they include the ancestors of modern birds), were semi-aquatic and specialised in eating fish and other small aquatic organisms. Unlike the Enantiornithes, which dominated land-based and arboreal habitats, most early euornithes lacked perching adaptations and likely included shorebird-like species, waders, and swimming and diving species. The latter included the superficially gull-like Ichthyornis and the Hesperornithiformes, which became so well adapted to hunting fish in marine environments that they lost the ability to fly and became primarily aquatic. The early euornithes also saw the development of many traits associated with modern birds, like strongly keeled breastbones, toothless, beaked portions of their jaws (though most non-avian euornithes retained teeth in other parts of the jaws). Euornithes also included the first avialans to develop true pygostyle and a fully mobile fan of tail feathers, which may have replaced the "hind wing" as the primary mode of aerial maneuverability and braking in flight. A study on mosaic evolution in the avian skull found that the last common ancestor of all Neornithes might have had a beak similar to that of the modern hook-billed vanga and a skull similar to that of the Eurasian golden oriole. As both species are small aerial and canopy foraging omnivores, a similar ecological niche was inferred for this hypothetical ancestor. Diversification of modern birds Most studies agree on a Cretaceous age for the most recent common ancestor of modern birds but estimates range from the Early Cretaceous to the latest Cretaceous. Similarly, there is no agreement on whether most of the early diversification of modern birds occurred in the Cretaceous and associated withe breakup of the supercontinent Gondwana or occurred later and potentially as a consequence of the Cretaceous–Palaeogene extinction event. This disagreement is in part caused by a divergence in the evidence; most molecular dating studies suggests a Cretaceous evolutionary radiation, while fossil evidence points to a Cenozoic radiation (the so-called 'rocks' versus 'clocks' controversy). The discovery of Vegavis from the Maastrichtian, the last stage of the Late Cretaceous proved that the diversification of modern birds started before the Cenozoic era. The affinities of an earlier fossil, the possible galliform Austinornis lentus, dated to about 85 million years ago, are still too controversial to provide a fossil evidence of modern bird diversification. In 2020, Asteriornis from the Maastrichtian was described, it appears to be a close relative of Galloanserae, the earliest diverging lineage within Neognathae. Attempts to reconcile molecular and fossil evidence using genomic-scale DNA data and comprehensive fossil information have not resolved the controversy. However, a 2015 estimate that used a new method for calibrating molecular clocks confirmed that while modern birds originated early in the Late Cretaceous, likely in Western Gondwana, a pulse of diversification in all major groups occurred around the Cretaceous–Palaeogene extinction event. Modern birds would have expanded from West Gondwana through two routes. One route was an Antarctic interchange in the Paleogene. The other route was probably via Paleocene land bridges between South American and North America, which allowed for the rapid expansion and diversification of Neornithes into the Holarctic and Paleotropics. On the other hand, the occurrence of Asteriornis in the Northern Hemisphere suggest that Neornithes dispersed out of East Gondwana before the Paleocene. Classification of bird orders All modern birds lie within the crown group Aves (alternately Neornithes), which has two subdivisions: the Palaeognathae, which includes the flightless ratites (such as the ostriches) and the weak-flying tinamous, and the extremely diverse Neognathae, containing all other birds. These two subdivisions have variously been given the rank of superorder, cohort, or infraclass. Depending on the taxonomic viewpoint, the number of known living bird species is around 10,906 although other sources may differ in their precise number. Cladogram of modern bird relationships based on Braun & Kimball (2021) The classification of birds is a contentious issue. Sibley and Ahlquist's Phylogeny and Classification of Birds (1990) is a landmark work on the subject. Most evidence seems to suggest the assignment of orders is accurate, but scientists disagree about the relationships among the orders themselves; evidence from modern bird anatomy, fossils and DNA have all been brought to bear on the problem, but no strong consensus has emerged. Fossil and molecular evidence from the 2010s is providing an increasingly clear picture of the evolution of modern bird orders. Genomics , the genome had been sequenced for only two birds, the chicken and the zebra finch. the genomes of 542 species of birds had been completed. At least one genome has been sequenced from every order. These include at least one species in about 90% of extant avian families (218 out of 236 families recognised by the Howard and Moore Checklist). Being able to sequence and compare whole genomes gives researchers many types of information, about genes, the DNA that regulates the genes, and their evolutionary history. This has led to reconsideration of some of the classifications that were based solely on the identification of protein-coding genes. Waterbirds such as pelicans and flamingos, for example, may have in common specific adaptations suited to their environment that were developed independently. Distribution Birds live and breed in most terrestrial habitats and on all seven continents, reaching their southern extreme in the snow petrel's breeding colonies up to inland in Antarctica. The highest bird diversity occurs in tropical regions. It was earlier thought that this high diversity was the result of higher speciation rates in the tropics; however studies from the 2000s found higher speciation rates in the high latitudes that were offset by greater extinction rates than in the tropics. Many species migrate annually over great distances and across oceans; several families of birds have adapted to life both on the world's oceans and in them, and some seabird species come ashore only to breed, while some penguins have been recorded diving up to deep. Many bird species have established breeding populations in areas to which they have been introduced by humans. Some of these introductions have been deliberate; the ring-necked pheasant, for example, has been introduced around the world as a game bird. Others have been accidental, such as the establishment of wild monk parakeets in several North American cities after their escape from captivity. Some species, including cattle egret, yellow-headed caracara and galah, have spread naturally far beyond their original ranges as agricultural expansion created alternative habitats although modern practices of intensive agriculture have negatively impacted farmland bird populations. Anatomy and physiology Compared with other vertebrates, birds have a body plan that shows many unusual adaptations, mostly to facilitate flight. Skeletal system The skeleton consists of very lightweight bones. They have large air-filled cavities (called pneumatic cavities) which connect with the respiratory system. The skull bones in adults are fused and do not show cranial sutures. The orbital cavities that house the eyeballs are large and separated from each other by a bony septum (partition). The spine has cervical, thoracic, lumbar and caudal regions with the number of cervical (neck) vertebrae highly variable and especially flexible, but movement is reduced in the anterior thoracic vertebrae and absent in the later vertebrae. The last few are fused with the pelvis to form the synsacrum. The ribs are flattened and the sternum is keeled for the attachment of flight muscles except in the flightless bird orders. The forelimbs are modified into wings. The wings are more or less developed depending on the species; the only known groups that lost their wings are the extinct moa and elephant birds. Excretory system Like the reptiles, birds are primarily uricotelic, that is, their kidneys extract nitrogenous waste from their bloodstream and excrete it as uric acid, instead of urea or ammonia, through the ureters into the intestine. Birds do not have a urinary bladder or external urethral opening and (with exception of the ostrich) uric acid is excreted along with faeces as a semisolid waste. However, birds such as hummingbirds can be facultatively ammonotelic, excreting most of the nitrogenous wastes as ammonia. They also excrete creatine, rather than creatinine like mammals. This material, as well as the output of the intestines, emerges from the bird's cloaca. The cloaca is a multi-purpose opening: waste is expelled through it, most birds mate by joining cloaca, and females lay eggs from it. In addition, many species of birds regurgitate pellets. It is a common but not universal feature of altricial passerine nestlings (born helpless, under constant parental care) that instead of excreting directly into the nest, they produce a fecal sac. This is a mucus-covered pouch that allows parents to either dispose of the waste outside the nest or to recycle the waste through their own digestive system. Reproductive system Males within Palaeognathae (with the exception of the kiwis), the Anseriformes (with the exception of screamers), and in rudimentary forms in Galliformes (but fully developed in Cracidae) possess a penis, which is never present in Neoaves. The length is thought to be related to sperm competition. For male birds to get an erection, they depend on lymphatic fluid instead of blood. When not copulating, it is hidden within the proctodeum compartment within the cloaca, just inside the vent. Female birds have sperm storage tubules that allow sperm to remain viable long after copulation, a hundred days in some species. Sperm from multiple males may compete through this mechanism. Most female birds have a single ovary and a single oviduct, both on the left side, but there are exceptions: species in at least 16 different orders of birds have two ovaries. Even these species, however, tend to have a single oviduct. It has been speculated that this might be an adaptation to flight, but males have two testes, and it is also observed that the gonads in both sexes decrease dramatically in size outside the breeding season. Also terrestrial birds generally have a single ovary, as does the platypus, an egg-laying mammal. A more likely explanation is that the egg develops a shell while passing through the oviduct over a period of about a day, so that if two eggs were to develop at the same time, there would be a risk to survival. While rare, mostly abortive, parthenogenesis is not unknown in birds and eggs can be diploid, automictic and results in male offspring. Birds are solely gonochoric. Meaning they have two sexes: either female or male. The sex of birds is determined by the Z and W sex chromosomes, rather than by the X and Y chromosomes present in mammals. Male birds have two Z chromosomes (ZZ), and female birds have a W chromosome and a Z chromosome (WZ). A complex system of disassortative mating with two morphs is involved in the white-throated sparrow Zonotrichia albicollis, where white- and tan-browed morphs of opposite sex pair, making it appear as if four sexes were involved since any individual is compatible with only a fourth of the population. In nearly all species of birds, an individual's sex is determined at fertilisation. However, one 2007 study claimed to demonstrate temperature-dependent sex determination among the Australian brushturkey, for which higher temperatures during incubation resulted in a higher female-to-male sex ratio. This, however, was later proven to not be the case. These birds do not exhibit temperature-dependent sex determination, but temperature-dependent sex mortality. Respiratory and circulatory systems Birds have one of the most complex respiratory systems of all animal groups. Upon inhalation, 75% of the fresh air bypasses the lungs and flows directly into a posterior air sac which extends from the lungs and connects with air spaces in the bones and fills them with air. The other 25% of the air goes directly into the lungs. When the bird exhales, the used air flows out of the lungs and the stored fresh air from the posterior air sac is simultaneously forced into the lungs. Thus, a bird's lungs receive a constant supply of fresh air during both inhalation and exhalation. Sound production is achieved using the syrinx, a muscular chamber incorporating multiple tympanic membranes which diverges from the lower end of the trachea; the trachea being elongated in some species, increasing the volume of vocalisations and the perception of the bird's size. In birds, the main arteries taking blood away from the heart originate from the right aortic arch (or pharyngeal arch), unlike in the mammals where the left aortic arch forms this part of the aorta. The postcava receives blood from the limbs via the renal portal system. Unlike in mammals, the circulating red blood cells in birds retain their nucleus. Heart type and features The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication. The heart itself is divided into a right and left half, each with an atrium and ventricle. The atrium and ventricles of each side are separated by atrioventricular valves which prevent back flow from one chamber to the next during contraction. Being myogenic, the heart's pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium. The sinoatrial node uses calcium to cause a depolarising signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles. The avian heart also consists of muscular arches that are made up of thick bundles of muscular layers. Much like a mammalian heart, the avian heart is composed of endocardial, myocardial and epicardial layers. The atrium walls tend to be thinner than the ventricle walls, due to the intense ventricular contraction used to pump oxygenated blood throughout the body. Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight. Organisation Birds have a very efficient system for diffusing oxygen into the blood; birds have a ten times greater surface area to gas exchange volume than mammals. As a result, birds have more blood in their capillaries per unit of volume of lung than a mammal. The arteries are composed of thick elastic muscles to withstand the pressure of the ventricular contractions, and become more rigid as they move away from the heart. Blood moves through the arteries, which undergo vasoconstriction, and into arterioles which act as a transportation system to distribute primarily oxygen as well as nutrients to all tissues of the body. As the arterioles move away from the heart and into individual organs and tissues they are further divided to increase surface area and slow blood flow. Blood travels through the arterioles and moves into the capillaries where gas exchange can occur. Capillaries are organised into capillary beds in tissues; it is here that blood exchanges oxygen for carbon dioxide waste. In the capillary beds, blood flow is slowed to allow maximum diffusion of oxygen into the tissues. Once the blood has become deoxygenated, it travels through venules then veins and back to the heart. Veins, unlike arteries, are thin and rigid as they do not need to withstand extreme pressure. As blood travels through the venules to the veins a funneling occurs called vasodilation bringing blood back to the heart. Once the blood reaches the heart, it moves first into the right atrium, then the right ventricle to be pumped through the lungs for further gas exchange of carbon dioxide waste for oxygen. Oxygenated blood then flows from the lungs through the left atrium to the left ventricle where it is pumped out to the body. Nervous system The nervous system is large relative to the bird's size. The most developed part of the brain of birds is the one that controls the flight-related functions, while the cerebellum coordinates movement and the cerebrum controls behaviour patterns, navigation, mating and nest building. Most birds have a poor sense of smell with notable exceptions including kiwis, New World vultures and tubenoses. The avian visual system is usually highly developed. Water birds have special flexible lenses, allowing accommodation for vision in air and water. Some species also have dual fovea. Birds are tetrachromatic, possessing ultraviolet (UV) sensitive cone cells in the eye as well as green, red and blue ones. They also have double cones, likely to mediate achromatic vision. Many birds show plumage patterns in ultraviolet that are invisible to the human eye; some birds whose sexes appear similar to the naked eye are distinguished by the presence of ultraviolet reflective patches on their feathers. Male blue tits have an ultraviolet reflective crown patch which is displayed in courtship by posturing and raising of their nape feathers. Ultraviolet light is also used in foraging—kestrels have been shown to search for prey by detecting the UV reflective urine trail marks left on the ground by rodents. With the exception of pigeons and a few other species, the eyelids of birds are not used in blinking. Instead the eye is lubricated by the nictitating membrane, a third eyelid that moves horizontally. The nictitating membrane also covers the eye and acts as a contact lens in many aquatic birds. The bird retina has a fan shaped blood supply system called the pecten. Eyes of most birds are large, not very round and capable of only limited movement in the orbits, typically 10–20°. Birds with eyes on the sides of their heads have a wide visual field, while birds with eyes on the front of their heads, such as owls, have binocular vision and can estimate the depth of field. The avian ear lacks external pinnae but is covered by feathers, although in some birds, such as the Asio, Bubo and Otus owls, these feathers form tufts which resemble ears. The inner ear has a cochlea, but it is not spiral as in mammals. Defence and intraspecific combat A few species are able to use chemical defences against predators; some Procellariiformes can eject an unpleasant stomach oil against an aggressor, and some species of pitohuis from New Guinea have a powerful neurotoxin in their skin and feathers. A lack of field observations limit our knowledge, but intraspecific conflicts are known to sometimes result in injury or death. The screamers (Anhimidae), some jacanas (Jacana, Hydrophasianus), the spur-winged goose (Plectropterus), the torrent duck (Merganetta) and nine species of lapwing (Vanellus) use a sharp spur on the wing as a weapon. The steamer ducks (Tachyeres), geese and swans (Anserinae), the solitaire (Pezophaps), sheathbills (Chionis), some guans (Crax) and stone curlews (Burhinus) use a bony knob on the alular metacarpal to punch and hammer opponents. The jacanas Actophilornis and Irediparra have an expanded, blade-like radius. The extinct Xenicibis was unique in having an elongate forelimb and massive hand which likely functioned in combat or defence as a jointed club or flail. Swans, for instance, may strike with the bony spurs and bite when defending eggs or young. Feathers, plumage, and scales Feathers are a feature characteristic of birds (though also present in some dinosaurs not currently considered to be true birds). They facilitate flight, provide insulation that aids in thermoregulation, and are used in display, camouflage, and signalling. There are several types of feathers, each serving its own set of purposes. Feathers are epidermal growths attached to the skin and arise only in specific tracts of skin called pterylae. The distribution pattern of these feather tracts (pterylosis) is used in taxonomy and systematics. The arrangement and appearance of feathers on the body, called plumage, may vary within species by age, social status, and sex. Plumage is regularly moulted; the standard plumage of a bird that has moulted after breeding is known as the "" plumage, or—in the Humphrey–Parkes terminology—"basic" plumage; breeding plumages or variations of the basic plumage are known under the Humphrey–Parkes system as "" plumages. Moulting is annual in most species, although some may have two moults a year, and large birds of prey may moult only once every few years. Moulting patterns vary across species. In passerines, flight feathers are replaced one at a time with the innermost being the first. When the fifth of sixth primary is replaced, the outermost begin to drop. After the innermost tertiaries are moulted, the starting from the innermost begin to drop and this proceeds to the outer feathers (centrifugal moult). The greater primary are moulted in synchrony with the primary that they overlap. A small number of species, such as ducks and geese, lose all of their flight feathers at once, temporarily becoming flightless. As a general rule, the tail feathers are moulted and replaced starting with the innermost pair. Centripetal moults of tail feathers are however seen in the Phasianidae. The centrifugal moult is modified in the tail feathers of woodpeckers and treecreepers, in that it begins with the second innermost pair of feathers and finishes with the central pair of feathers so that the bird maintains a functional climbing tail. The general pattern seen in passerines is that the primaries are replaced outward, secondaries inward, and the tail from centre outward. Before nesting, the females of most bird species gain a bare brood patch by losing feathers close to the belly. The skin there is well supplied with blood vessels and helps the bird in incubation. Feathers require maintenance and birds preen or groom them daily, spending an average of around 9% of their daily time on this. The bill is used to brush away foreign particles and to apply waxy secretions from the uropygial gland; these secretions protect the feathers' flexibility and act as an antimicrobial agent, inhibiting the growth of feather-degrading bacteria. This may be supplemented with the secretions of formic acid from ants, which birds receive through a behaviour known as anting, to remove feather parasites. The scales of birds are composed of the same keratin as beaks, claws, and spurs. They are found mainly on the toes and metatarsus, but may be found further up on the ankle in some birds. Most bird scales do not overlap significantly, except in the cases of kingfishers and woodpeckers. The scales of birds are thought to be homologous to those of reptiles and mammals. Flight Most birds can fly, which distinguishes them from almost all other vertebrate classes. Flight is the primary means of locomotion for most bird species and is used for searching for food and for escaping from predators. Birds have various adaptations for flight, including a lightweight skeleton, two large flight muscles, the pectoralis (which accounts for 15% of the total mass of the bird) and the supracoracoideus, as well as a modified forelimb (wing) that serves as an aerofoil. Wing shape and size generally determine a bird's flight style and performance; many birds combine powered, flapping flight with less energy-intensive soaring flight. About 60 extant bird species are flightless, as were many extinct birds. Flightlessness often arises in birds on isolated islands, most likely due to limited resources and the absence of mammalian land predators. Flightlessness is almost exclusively correlated with gigantism due to an island's inherent condition of isolation. Although flightless, penguins use similar musculature and movements to "fly" through the water, as do some flight-capable birds such as auks, shearwaters and dippers. Behaviour Most birds are diurnal, but some birds, such as many species of owls and nightjars, are nocturnal or crepuscular (active during twilight hours), and many coastal waders feed when the tides are appropriate, by day or night. Diet and feeding are varied and often include nectar, fruit, plants, seeds, carrion, and various small animals, including other birds. The digestive system of birds is unique, with a crop for storage and a gizzard that contains swallowed stones for grinding food to compensate for the lack of teeth. Some species such as pigeons and some psittacine species do not have a gallbladder. Most birds are highly adapted for rapid digestion to aid with flight. Some migratory birds have adapted to use protein stored in many parts of their bodies, including protein from the intestines, as additional energy during migration. Birds that employ many strategies to obtain food or feed on a variety of food items are called generalists, while others that concentrate time and effort on specific food items or have a single strategy to obtain food are considered specialists. Avian foraging strategies can vary widely by species. Many birds glean for insects, invertebrates, fruit, or seeds. Some hunt insects by suddenly attacking from a branch. Those species that seek pest insects are considered beneficial 'biological control agents' and their presence encouraged in biological pest control programmes. Combined, insectivorous birds eat 400–500 million metric tons of arthropods annually. Nectar feeders such as hummingbirds, sunbirds, lories, and lorikeets amongst others have specially adapted brushy tongues and in many cases bills designed to fit co-adapted flowers. Kiwis and shorebirds with long bills probe for invertebrates; shorebirds' varied bill lengths and feeding methods result in the separation of ecological niches. Loons, diving ducks, penguins and auks pursue their prey underwater, using their wings or feet for propulsion, while aerial predators such as sulids, kingfishers and terns plunge dive after their prey. Flamingos, three species of prion, and some ducks are filter feeders. Geese and dabbling ducks are primarily grazers. Some species, including frigatebirds, gulls, and skuas, engage in kleptoparasitism, stealing food items from other birds. Kleptoparasitism is thought to be a supplement to food obtained by hunting, rather than a significant part of any species' diet; a study of great frigatebirds stealing from masked boobies estimated that the frigatebirds stole at most 40% of their food and on average stole only 5%. Other birds are scavengers; some of these, like vultures, are specialised carrion eaters, while others, like gulls, corvids, or other birds of prey, are opportunists. Water and drinking Water is needed by many birds although their mode of excretion and lack of sweat glands reduces the physiological demands. Some desert birds can obtain their water needs entirely from moisture in their food. They may also have other adaptations such as allowing their body temperature to rise, saving on moisture loss from evaporative cooling or panting. Seabirds can drink seawater and have salt glands inside the head that eliminate excess salt out of the nostrils. Most birds scoop water in their beaks and raise their head to let water run down the throat. Some species, especially of arid zones, belonging to the pigeon, finch, mousebird, button-quail and bustard families are capable of sucking up water without the need to tilt back their heads. Some desert birds depend on water sources and sandgrouse are particularly well known for their daily congregations at waterholes. Nesting sandgrouse and many plovers carry water to their young by wetting their belly feathers. Some birds carry water for chicks at the nest in their crop or regurgitate it along with food. The pigeon family, flamingos and penguins have adaptations to produce a nutritive fluid called crop milk that they provide to their chicks. Feather care Feathers, being critical to the survival of a bird, require maintenance. Apart from physical wear and tear, feathers face the onslaught of fungi, ectoparasitic feather mites and bird lice. The physical condition of feathers are maintained by often with the application of secretions from the . Birds also bathe in water or dust themselves. While some birds dip into shallow water, more aerial species may make aerial dips into water and arboreal species often make use of dew or rain that collect on leaves. Birds of arid regions make use of loose soil to dust-bathe. A behaviour termed as anting in which the bird encourages ants to run through their plumage is also thought to help them reduce the ectoparasite load in feathers. Many species will spread out their wings and expose them to direct sunlight and this too is thought to help in reducing fungal and ectoparasitic activity that may lead to feather damage. Migration Many bird species migrate to take advantage of global differences of seasonal temperatures, therefore optimising availability of food sources and breeding habitat. These migrations vary among the different groups. Many landbirds, shorebirds, and waterbirds undertake annual long-distance migrations, usually triggered by the length of daylight as well as weather conditions. These birds are characterised by a breeding season spent in the temperate or polar regions and a non-breeding season in the tropical regions or opposite hemisphere. Before migration, birds substantially increase body fats and reserves and reduce the size of some of their organs. Migration is highly demanding energetically, particularly as birds need to cross deserts and oceans without refuelling. Landbirds have a flight range of around and shorebirds can fly up to , although the bar-tailed godwit is capable of non-stop flights of up to . Seabirds also undertake long migrations, the longest annual migration being those of sooty shearwaters, which nest in New Zealand and Chile and spend the northern summer feeding in the North Pacific off Japan, Alaska and California, an annual round trip of . Other seabirds disperse after breeding, travelling widely but having no set migration route. Albatrosses nesting in the Southern Ocean often undertake circumpolar trips between breeding seasons. Some bird species undertake shorter migrations, travelling only as far as is required to avoid bad weather or obtain food. Irruptive species such as the boreal finches are one such group and can commonly be found at a location in one year and absent the next. This type of migration is normally associated with food availability. Species may also travel shorter distances over part of their range, with individuals from higher latitudes travelling into the existing range of conspecifics; others undertake partial migrations, where only a fraction of the population, usually females and subdominant males, migrates. Partial migration can form a large percentage of the migration behaviour of birds in some regions; in Australia, surveys found that 44% of non-passerine birds and 32% of passerines were partially migratory. Altitudinal migration is a form of short-distance migration in which birds spend the breeding season at higher altitudes and move to lower ones during suboptimal conditions. It is most often triggered by temperature changes and usually occurs when the normal territories also become inhospitable due to lack of food. Some species may also be nomadic, holding no fixed territory and moving according to weather and food availability. Parrots as a family are overwhelmingly neither migratory nor sedentary but considered to either be dispersive, irruptive, nomadic or undertake small and irregular migrations. The ability of birds to return to precise locations across vast distances has been known for some time; in an experiment conducted in the 1950s, a Manx shearwater released in Boston in the United States returned to its colony in Skomer, in Wales within 13 days, a distance of . Birds navigate during migration using a variety of methods. For diurnal migrants, the sun is used to navigate by day, and a stellar compass is used at night. Birds that use the sun compensate for the changing position of the sun during the day by the use of an internal clock. Orientation with the stellar compass depends on the position of the constellations surrounding Polaris. These are backed up in some species by their ability to sense the Earth's geomagnetism through specialised photoreceptors. Communication Birds communicate primarily using visual and auditory signals. Signals can be interspecific (between species) and intraspecific (within species). Birds sometimes use plumage to assess and assert social dominance, to display breeding condition in sexually selected species, or to make threatening displays, as in the sunbittern's mimicry of a large predator to ward off hawks and protect young chicks. Visual communication among birds may also involve ritualised displays, which have developed from non-signalling actions such as preening, the adjustments of feather position, pecking, or other behaviour. These displays may signal aggression or submission or may contribute to the formation of pair-bonds. The most elaborate displays occur during courtship, where "dances" are often formed from complex combinations of many possible component movements; males' breeding success may depend on the quality of such displays. Bird calls and songs, which are produced in the syrinx, are the major means by which birds communicate with sound. This communication can be very complex; some species can operate the two sides of the syrinx independently, allowing the simultaneous production of two different songs. Calls are used for a variety of purposes, including mate attraction, evaluation of potential mates, bond formation, the claiming and maintenance of territories, the identification of other individuals (such as when parents look for chicks in colonies or when mates reunite at the start of breeding season), and the warning of other birds of potential predators, sometimes with specific information about the nature of the threat. Some birds also use mechanical sounds for auditory communication. The Coenocorypha snipes of New Zealand drive air through their feathers, woodpeckers drum for long-distance communication, and palm cockatoos use tools to drum. Flocking and other associations While some birds are essentially territorial or live in small family groups, other birds may form large flocks. The principal benefits of flocking are safety in numbers and increased foraging efficiency. Defence against predators is particularly important in closed habitats like forests, where ambush predation is common and multiple eyes can provide a valuable early warning system. This has led to the development of many mixed-species feeding flocks, which are usually composed of small numbers of many species; these flocks provide safety in numbers but increase potential competition for resources. Costs of flocking include bullying of socially subordinate birds by more dominant birds and the reduction of feeding efficiency in certain cases. Birds sometimes also form associations with non-avian species. Plunge-diving seabirds associate with dolphins and tuna, which push shoaling fish towards the surface. Some species of hornbills have a mutualistic relationship with dwarf mongooses, in which they forage together and warn each other of nearby birds of prey and other predators. Resting and roosting The high metabolic rates of birds during the active part of the day is supplemented by rest at other times. Sleeping birds often use a type of sleep known as vigilant sleep, where periods of rest are interspersed with quick eye-opening "peeks", allowing them to be sensitive to disturbances and enable rapid escape from threats. Swifts are believed to be able to sleep in flight and radar observations suggest that they orient themselves to face the wind in their roosting flight. It has been suggested that there may be certain kinds of sleep which are possible even when in flight. Some birds have also demonstrated the capacity to fall into slow-wave sleep one hemisphere of the brain at a time. The birds tend to exercise this ability depending upon its position relative to the outside of the flock. This may allow the eye opposite the sleeping hemisphere to remain vigilant for predators by viewing the outer margins of the flock. This adaptation is also known from marine mammals. Communal roosting is common because it lowers the loss of body heat and decreases the risks associated with predators. Roosting sites are often chosen with regard to thermoregulation and safety. Unusual mobile roost sites include large herbivores on the African savanna that are used by oxpeckers. Many sleeping birds bend their heads over their backs and tuck their bills in their back feathers, although others place their beaks among their breast feathers. Many birds rest on one leg, while some may pull up their legs into their feathers, especially in cold weather. Perching birds have a tendon-locking mechanism that helps them hold on to the perch when they are asleep. Many ground birds, such as quails and pheasants, roost in trees. A few parrots of the genus Loriculus roost hanging upside down. Some hummingbirds go into a nightly state of torpor accompanied with a reduction of their metabolic rates. This physiological adaptation shows in nearly a hundred other species, including owlet-nightjars, nightjars, and woodswallows. One species, the common poorwill, even enters a state of hibernation. Birds do not have sweat glands, but can lose water directly through the skin, and they may cool themselves by moving to shade, standing in water, panting, increasing their surface area, fluttering their throat or using special behaviours like urohidrosis to cool themselves. Breeding Social systems Ninety-five per cent of bird species are socially monogamous. These species pair for at least the length of the breeding season or—in some cases—for several years or until the death of one mate. Monogamy allows for both paternal care and biparental care, which is especially important for species in which care from both the female and the male parent is required in order to successfully rear a brood. Among many socially monogamous species, extra-pair copulation (infidelity) is common. Such behaviour typically occurs between dominant males and females paired with subordinate males, but may also be the result of forced copulation in ducks and other anatids. For females, possible benefits of extra-pair copulation include getting better genes for her offspring and insuring against the possibility of infertility in her mate. Males of species that engage in extra-pair copulations will closely guard their mates to ensure the parentage of the offspring that they raise. Other mating systems, including polygyny, polyandry, polygamy, polygynandry, and promiscuity, also occur. Polygamous breeding systems arise when females are able to raise broods without the help of males. Mating systems vary across bird families but variations within species are thought to be driven by environmental conditions. Breeding usually involves some form of courtship display, typically performed by the male. Most displays are rather simple and involve some type of song. Some displays, however, are quite elaborate. Depending on the species, these may include wing or tail drumming, dancing, aerial flights, or communal lekking. Females are generally the ones that drive partner selection, although in the polyandrous phalaropes, this is reversed: plainer males choose brightly coloured females. Courtship feeding, billing and are commonly performed between partners, generally after the birds have paired and mated. Homosexual behaviour has been observed in males or females in numerous species of birds, including copulation, pair-bonding, and joint parenting of chicks. Over 130 avian species around the world engage in sexual interactions between the same sex or homosexual behaviours. "Same-sex courtship activities may involve elaborate displays, synchronized dances, gift-giving ceremonies, or behaviors at specific display areas including bowers, arenas, or leks." Territories, nesting and incubation Many birds actively defend a territory from others of the same species during the breeding season; maintenance of territories protects the food source for their chicks. Species that are unable to defend feeding territories, such as seabirds and swifts, often breed in colonies instead; this is thought to offer protection from predators. Colonial breeders defend small nesting sites, and competition between and within species for nesting sites can be intense. All birds lay amniotic eggs with hard shells made mostly of calcium carbonate. Hole and burrow nesting species tend to lay white or pale eggs, while open nesters lay camouflaged eggs. There are many exceptions to this pattern, however; the ground-nesting nightjars have pale eggs, and camouflage is instead provided by their plumage. Species that are victims of brood parasites have varying egg colours to improve the chances of spotting a parasite's egg, which forces female parasites to match their eggs to those of their hosts. Bird eggs are usually laid in a nest. Most species create somewhat elaborate nests, which can be cups, domes, plates, mounds, or burrows. Some bird nests can be a simple scrape, with minimal or no lining; most seabird and wader nests are no more than a scrape on the ground. Most birds build nests in sheltered, hidden areas to avoid predation, but large or colonial birds—which are more capable of defence—may build more open nests. During nest construction, some species seek out plant matter from plants with parasite-reducing toxins to improve chick survival, and feathers are often used for nest insulation. Some bird species have no nests; the cliff-nesting common guillemot lays its eggs on bare rock, and male emperor penguins keep eggs between their body and feet. The absence of nests is especially prevalent in open habitat ground-nesting species where any addition of nest material would make the nest more conspicuous. Many ground nesting birds lay a clutch of eggs that hatch synchronously, with precocial chicks led away from the nests (nidifugous) by their parents soon after hatching. Incubation, which regulates temperature for chick development, usually begins after the last egg has been laid. In monogamous species incubation duties are often shared, whereas in polygamous species one parent is wholly responsible for incubation. Warmth from parents passes to the eggs through brood patches, areas of bare skin on the abdomen or breast of the incubating birds. Incubation can be an energetically demanding process; adult albatrosses, for instance, lose as much as of body weight per day of incubation. The warmth for the incubation of the eggs of megapodes comes from the sun, decaying vegetation or volcanic sources. Incubation periods range from 10 days (in woodpeckers, cuckoos and passerine birds) to over 80 days (in albatrosses and kiwis). The diversity of characteristics of birds is great, sometimes even in closely related species. Several avian characteristics are compared in the table below. Parental care and fledging At the time of their hatching, chicks range in development from helpless to independent, depending on their species. Helpless chicks are termed altricial, and tend to be born small, blind, immobile and naked; chicks that are mobile and feathered upon hatching are termed precocial. Altricial chicks need help thermoregulating and must be brooded for longer than precocial chicks. The young of many bird species do not precisely fit into either the precocial or altricial category, having some aspects of each and thus fall somewhere on an "altricial-precocial spectrum". Chicks at neither extreme but favouring one or the other may be termed or . The length and nature of parental care varies widely amongst different orders and species. At one extreme, parental care in megapodes ends at hatching; the newly hatched chick digs itself out of the nest mound without parental assistance and can fend for itself immediately. At the other extreme, many seabirds have extended periods of parental care, the longest being that of the great frigatebird, whose chicks take up to six months to fledge and are fed by the parents for up to an additional 14 months. The chick guard stage describes the period of breeding during which one of the adult birds is permanently present at the nest after chicks have hatched. The main purpose of the guard stage is to aid offspring to thermoregulate and protect them from predation. In some species, both parents care for nestlings and fledglings; in others, such care is the responsibility of only one sex. In some species, other members of the same species—usually close relatives of the breeding pair, such as offspring from previous broods—will help with the raising of the young. Such alloparenting is particularly common among the Corvida, which includes such birds as the true crows, Australian magpie and fairy-wrens, but has been observed in species as different as the rifleman and red kite. Among most groups of animals, male parental care is rare. In birds, however, it is quite common—more so than in any other vertebrate class. Although territory and nest site defence, incubation, and chick feeding are often shared tasks, there is sometimes a division of labour in which one mate undertakes all or most of a particular duty. The point at which chicks fledge varies dramatically. The chicks of the Synthliboramphus murrelets, like the ancient murrelet, leave the nest the night after they hatch, following their parents out to sea, where they are raised away from terrestrial predators. Some other species, such as ducks, move their chicks away from the nest at an early age. In most species, chicks leave the nest just before, or soon after, they are able to fly. The amount of parental care after fledging varies; albatross chicks leave the nest on their own and receive no further help, while other species continue some supplementary feeding after fledging. Chicks may also follow their parents during their first migration. Brood parasites Brood parasitism, in which an egg-layer leaves her eggs with another individual's brood, is more common among birds than any other type of organism. After a parasitic bird lays her eggs in another bird's nest, they are often accepted and raised by the host at the expense of the host's own brood. Brood parasites may be either obligate brood parasites, which must lay their eggs in the nests of other species because they are incapable of raising their own young, or non-obligate brood parasites, which sometimes lay eggs in the nests of conspecifics to increase their reproductive output even though they could have raised their own young. One hundred bird species, including honeyguides, icterids, and ducks, are obligate parasites, though the most famous are the cuckoos. Some brood parasites are adapted to hatch before their host's young, which allows them to destroy the host's eggs by pushing them out of the nest or to kill the host's chicks; this ensures that all food brought to the nest will be fed to the parasitic chicks. Sexual selection Birds have evolved a variety of mating behaviours, with the peacock tail being perhaps the most famous example of sexual selection and the Fisherian runaway. Commonly occurring sexual dimorphisms such as size and colour differences are energetically costly attributes that signal competitive breeding situations. Many types of avian sexual selection have been identified; intersexual selection, also known as female choice; and intrasexual competition, where individuals of the more abundant sex compete with each other for the privilege to mate. Sexually selected traits often evolve to become more pronounced in competitive breeding situations until the trait begins to limit the individual's fitness. Conflicts between an individual fitness and signalling adaptations ensure that sexually selected ornaments such as plumage colouration and courtship behaviour are "honest" traits. Signals must be costly to ensure that only good-quality individuals can present these exaggerated sexual ornaments and behaviours. Inbreeding depression Inbreeding causes early death (inbreeding depression) in the zebra finch Taeniopygia guttata. Embryo survival (that is, hatching success of fertile eggs) was significantly lower for sib-sib mating pairs than for unrelated pairs. Darwin's finch Geospiza scandens experiences inbreeding depression (reduced survival of offspring) and the magnitude of this effect is influenced by environmental conditions such as low food availability. Inbreeding avoidance Incestuous matings by the purple-crowned fairy wren Malurus coronatus result in severe fitness costs due to inbreeding depression (greater than 30% reduction in hatchability of eggs). Females paired with related males may undertake extra pair matings (see Promiscuity#Other animals for 90% frequency in avian species) that can reduce the negative effects of inbreeding. However, there are ecological and demographic constraints on extra pair matings. Nevertheless, 43% of broods produced by incestuously paired females contained extra pair young. Inbreeding depression occurs in the great tit (Parus major) when the offspring produced as a result of a mating between close relatives show reduced fitness. In natural populations of Parus major, inbreeding is avoided by dispersal of individuals from their birthplace, which reduces the chance of mating with a close relative. Southern pied babblers Turdoides bicolor appear to avoid inbreeding in two ways. The first is through dispersal, and the second is by avoiding familiar group members as mates. Cooperative breeding in birds typically occurs when offspring, usually males, delay dispersal from their natal group in order to remain with the family to help rear younger kin. Female offspring rarely stay at home, dispersing over distances that allow them to breed independently, or to join unrelated groups. In general, inbreeding is avoided because it leads to a reduction in progeny fitness (inbreeding depression) due largely to the homozygous expression of deleterious recessive alleles. Cross-fertilisation between unrelated individuals ordinarily leads to the masking of deleterious recessive alleles in progeny. Ecology Birds occupy a wide range of ecological positions. While some birds are generalists, others are highly specialised in their habitat or food requirements. Even within a single habitat, such as a forest, the niches occupied by different species of birds vary, with some species feeding in the forest canopy, others beneath the canopy, and still others on the forest floor. Forest birds may be insectivores, frugivores, or nectarivores. Aquatic birds generally feed by fishing, plant eating, and piracy or kleptoparasitism. Many grassland birds are granivores. Birds of prey specialise in hunting mammals or other birds, while vultures are specialised scavengers. Birds are also preyed upon by a range of mammals including a few avivorous bats. A wide range of endo- and ectoparasites depend on birds and some parasites that are transmitted from parent to young have co-evolved and show host-specificity. Some nectar-feeding birds are important pollinators, and many frugivores play a key role in seed dispersal. Plants and pollinating birds often coevolve, and in some cases a flower's primary pollinator is the only species capable of reaching its nectar. Birds are often important to island ecology. Birds have frequently reached islands that mammals have not; on those islands, birds may fulfil ecological roles typically played by larger animals. For example, in New Zealand nine species of moa were important browsers, as are the kererū and kokako today. Today the plants of New Zealand retain the defensive adaptations evolved to protect them from the extinct moa. Many birds act as ecosystem engineers through the construction of nests, which provide important microhabitats and food for hundreds of species of invertebrates. Nesting seabirds may affect the ecology of islands and surrounding seas, principally through the concentration of large quantities of guano, which may enrich the local soil and the surrounding seas. A wide variety of avian ecology field methods, including counts, nest monitoring, and capturing and marking, are used for researching avian ecology. Relationship with humans Since birds are highly visible and common animals, humans have had a relationship with them since the dawn of man. Sometimes, these relationships are mutualistic, like the cooperative honey-gathering among honeyguides and African peoples such as the Borana. Other times, they may be commensal, as when species such as the house sparrow have benefited from human activities. Several bird species have become commercially significant agricultural pests, and some pose an aviation hazard. Human activities can also be detrimental, and have threatened numerous bird species with extinction (hunting, avian lead poisoning, pesticides, roadkill, wind turbine kills and predation by pet cats and dogs are common causes of death for birds). Birds can act as vectors for spreading diseases such as psittacosis, salmonellosis, campylobacteriosis, mycobacteriosis (avian tuberculosis), avian influenza (bird flu), giardiasis, and cryptosporidiosis over long distances. Some of these are zoonotic diseases that can also be transmitted to humans. Economic importance Domesticated birds raised for meat and eggs, called poultry, are the largest source of animal protein eaten by humans; in 2003, tons of poultry and tons of eggs were produced worldwide. Chickens account for much of human poultry consumption, though domesticated turkeys, ducks, and geese are also relatively common. Many species of birds are also hunted for meat. Bird hunting is primarily a recreational activity except in extremely undeveloped areas. The most important birds hunted in North and South America are waterfowl; other widely hunted birds include pheasants, wild turkeys, quail, doves, partridge, grouse, snipe, and woodcock. Muttonbirding is also popular in Australia and New Zealand. Although some hunting, such as that of muttonbirds, may be sustainable, hunting has led to the extinction or endangerment of dozens of species. Other commercially valuable products from birds include feathers (especially the down of geese and ducks), which are used as insulation in clothing and bedding, and seabird faeces (guano), which is a valuable source of phosphorus and nitrogen. The War of the Pacific, sometimes called the Guano War, was fought in part over the control of guano deposits. Birds have been domesticated by humans both as pets and for practical purposes. Colourful birds, such as parrots and mynas, are bred in captivity or kept as pets, a practice that has led to the illegal trafficking of some endangered species. Falcons and cormorants have long been used for hunting and fishing, respectively. Messenger pigeons, used since at least 1 AD, remained important as recently as World War II. Today, such activities are more common either as hobbies, for entertainment and tourism, Amateur bird enthusiasts (called birdwatchers, twitchers or, more commonly, birders) number in the millions. Many homeowners erect bird feeders near their homes to attract various species. Bird feeding has grown into a multimillion-dollar industry; for example, an estimated 75% of households in Britain provide food for birds at some point during the winter. In religion and mythology Birds play prominent and diverse roles in religion and mythology. In religion, birds may serve as either messengers or priests and leaders for a deity, such as in the Cult of Makemake, in which the Tangata manu of Easter Island served as chiefs or as attendants, as in the case of Hugin and Munin, the two common ravens who whispered news into the ears of the Norse god Odin. In several civilisations of ancient Italy, particularly Etruscan and Roman religion, priests were involved in augury, or interpreting the words of birds while the "auspex" (from which the word "auspicious" is derived) watched their activities to foretell events. They may also serve as religious symbols, as when Jonah (, dove) embodied the fright, passivity, mourning, and beauty traditionally associated with doves. Birds have themselves been deified, as in the case of the common peacock, which is perceived as Mother Earth by the people of southern India. In the ancient world, doves were used as symbols of the Mesopotamian goddess Inanna (later known as Ishtar), the Canaanite mother goddess Asherah, and the Greek goddess Aphrodite. In ancient Greece, Athena, the goddess of wisdom and patron deity of the city of Athens, had a little owl as her symbol. In religious images preserved from the Inca and Tiwanaku empires, birds are depicted in the process of transgressing boundaries between earthly and underground spiritual realms. Indigenous peoples of the central Andes maintain legends of birds passing to and from metaphysical worlds. In culture and folklore Birds have featured in culture and art since prehistoric times, when they were represented in early cave painting and carvings. Some birds have been perceived as monsters, including the mythological Roc and the Māori's legendary , a giant bird capable of snatching humans. Birds were later used as symbols of power, as in the magnificent Peacock Throne of the Mughal and Persian emperors. With the advent of scientific interest in birds, many paintings of birds were commissioned for books. Among the most famous of these bird artists was John James Audubon, whose paintings of North American birds were a great commercial success in Europe and who later lent his name to the National Audubon Society. Birds are also important figures in poetry; for example, Homer incorporated nightingales into his Odyssey, and Catullus used a sparrow as an erotic symbol in his Catullus 2. The relationship between an albatross and a sailor is the central theme of Samuel Taylor Coleridge's The Rime of the Ancient Mariner, which led to the use of the term as a metaphor for a 'burden'. Other English metaphors derive from birds; vulture funds and vulture investors, for instance, take their name from the scavenging vulture. Aircraft, particularly military aircraft, are frequently named after birds. The predatory nature of raptors make them popular choices for fighter aircraft such as the F-16 Fighting Falcon and the Harrier Jump Jet, while the names of seabirds may be chosen for aircraft primarily used by naval forces such as the HU-16 Albatross and the V-22 Osprey. Perceptions of bird species vary across cultures. Owls are associated with bad luck, witchcraft, and death in parts of Africa, but are regarded as wise across much of Europe. Hoopoes were considered sacred in Ancient Egypt and symbols of virtue in Persia, but were thought of as thieves across much of Europe and harbingers of war in Scandinavia. In heraldry, birds, especially eagles, often appear in coats of arms In vexillology, birds are a popular choice on flags. Birds feature in the flag designs of 17 countries and numerous subnational entities and territories. Birds are used by nations to symbolize a country's identity and heritage, with 91 countries officially recognizing a national bird. Birds of prey are highly represented, though some nations have chosen other species of birds with parrots being popular among smaller, tropical nations. In music In music, birdsong has influenced composers and musicians in several ways: they can be inspired by birdsong; they can intentionally imitate bird song in a composition, as Vivaldi, Messiaen, and Beethoven did, along with many later composers; they can incorporate recordings of birds into their works, as Ottorino Respighi first did; or like Beatrice Harrison and David Rothenberg, they can duet with birds. A 2023 archaeological excavation of a 10000-year-old site in Israel yielded hollow wing bones of coots and ducks with perforations made on the side that are thought to have allowed them to be used as flutes or whistles possibly used by Natufian people to lure birds of prey. Conservation Although human activities have allowed the expansion of a few species, such as the barn swallow and European starling, they have caused population decreases or extinction in many other species. Over a hundred bird species have gone extinct in historical times, although the most dramatic human-caused avian extinctions, eradicating an estimated 750–1800 species, occurred during the human colonisation of Melanesian, Polynesian, and Micronesian islands. Many bird populations are declining worldwide, with 1,227 species listed as threatened by BirdLife International and the IUCN in 2009. The most commonly cited human threat to birds is habitat loss. Other threats include overhunting, accidental mortality due to collisions with buildings or vehicles, long-line fishing bycatch, pollution (including oil spills and pesticide use), competition and predation from nonnative invasive species, and climate change. Governments and conservation groups work to protect birds, either by passing laws that preserve and restore bird habitat or by establishing captive populations for reintroductions. Such projects have produced some successes; one study estimated that conservation efforts saved 16 species of bird that would otherwise have gone extinct between 1994 and 2004, including the California condor and Norfolk parakeet.

...Baby One More Time (album)

...Baby One More Time is the debut studio album by American singer Britney Spears. It was released on January 12, 1999, by Jive Records. Spears had been a child performer on The All-New Mickey Mouse Club from 1993 to 1994, and was looking to expand her career as a teen singer. After being turned away by several record companies, Spears signed with Jive for a multi-album deal in 1997. She travelled to Sweden to collaborate with producers Max Martin and Rami Yacoub, who had been writing songs with producer Denniz Pop and others, for ...Baby One More Time. Their collaboration created a pop, bubblegum pop, dance-pop, and teen pop record, with Spears later saying that she felt excited when she heard it and knew it was going to be a hit record. The album was completed in June 1998. Upon its release, ...Baby One More Time garnered mixed reviews from music critics, with many praising its commercial appeal but deeming it silly and premature. Despite its initial mixed reception, it helped Spears receive a nomination for Best New Artist at the 42nd Annual Grammy Awards (2000). Retrospectively, it has been hailed for its major impact on pop culture, citing it as one of the most influential pop records of all time. A massive global commercial success, it made Spears the fifth artist under the age of 18 to top the US Billboard 200. It has been certified 14× platinum (diamond) by the Recording Industry Association of America (RIAA). Spears's best-selling album, it has sold over 25 million copies worldwide, making it one of the best-selling albums of all time, as well as the best-selling debut album by a female artist. ...Baby One More Time produced five singles. The lead single, "...Baby One More Time", brought Spears tremendous global success, reaching number one in most countries it charted in and becoming one of the best-selling physical singles of all time. In 2020, it was named the greatest debut single of all time by Rolling Stone. Subsequent singles "Sometimes" and "Born to Make You Happy" peaked within the top ten in most international countries while "(You Drive Me) Crazy" became Spears's second US Billboard Hot 100 top-ten hit. Spears heavily promoted the album through interviews and televised performances. Furthermore, she embarked on her first headlining concert tour, entitled ...Baby One More Time Tour (1999) and later continued with (You Drive Me) Crazy Tour (2000). Recording and production In June 1997, Spears was in talks with then-manager Lou Pearlman to join the female pop group Innosense. Her mother, Lynne Spears, asked family friend and entertainment lawyer Larry Rudolph for his opinion and submitted a tape of Spears singing over a Whitney Houston karaoke song along with some pictures. Rudolph decided to pitch her to record labels, which required a professional demo. He sent Spears an unused song from Toni Braxton; she rehearsed for a week and recorded in a studio with an audio engineer. Spears traveled from her hometown Kentwood, Louisiana, to New York City with the demo and met executives from four labels, returning to Kentwood the same day. Three rejected her, arguing audiences wanted pop bands such as the Backstreet Boys and the Spice Girls, and "there wasn't going to be another Madonna, another Debbie Gibson or another Tiffany." Two weeks later, executives from Jive Records returned calls to Rudolph. Jive's senior vice president of A&R Jeff Fenster stated: "It's very rare to hear someone that age who can deliver emotional content and commercial appeal. [...] For any artist, the motivation—the 'eye of the tiger'—is extremely important. And Britney had that." Jive soon appointed Britney to work with producer Eric Foster White for a month, who reportedly shaped her voice from "lower and less poppy" delivery to "distinctively, unmistakably Britney." One of the first songs Spears recorded with Foster White was "From the Bottom of My Broken Heart", which was released as the album's 4th single. Foster White also produced "Autumn Goodbye", which was the B-side to Spears' debut single "...Baby One More Time". During the same session for "Autumn Goodbye", Spears and Foster White also worked on a song called "Love Is On", which ultimately did not make the album and was later given to Sharon Cuneta. Spears recorded a lot of material with Eric Foster White, such as "Autumn Goodbye", "E-Mail My Heart", "From the Bottom of My Broken Heart", "I'm So Curious", "I Will Still Love You", "Way It Is Loving You", "I'll Be There For You", "Soda Pop", "Thinkin' About You", "Nothing Less Than Real", "Wishing on a Falling Star" and a cover of "You Got It All" by the Jets. She also recorded a cover of Sonny & Cher's 1967 single "The Beat Goes On". White was responsible for the vocal recording and song production, while additional production was handled by English electronic music group All Seeing I. After hearing the material, Jive Records president Clive Calder ordered a full studio album. Spears flew to Cheiron Studios in Stockholm, where half of ...Baby One More Time was recorded from May 1998, with producers Max Martin and Rami Yacoub, and contributions from others, including songwriting from Denniz Pop, who was too ill to attend any recording sessions. Martin showed Spears and her management a track titled "Hit Me Baby One More Time", originally written for American group TLC, who had rejected it. Spears later said that she felt excited when she heard it and knew it was going to be a hit. "We at Jive said, 'This is a fuckin' smash, revealed the label's A&R executive, Steven Lunt; however, other executives were concerned that the line "Hit Me" would condone domestic violence, and later revised it to "...Baby One More Time". Spears revealed that she "didn't do well at all the first day in the studio [recording the song], I was just too nervous. So I went out that night and had some fun. The next day I was completely relaxed and nailed it. You gotta be relaxed singing '... Baby One More Time'." By June 1998, the album had been completed. Music and lyrics Spears originally envisioned "Sheryl Crow music, but younger – more adult contemporary" for ...Baby One More Time, but acquiesced to the wishes of her label, since "It made more sense to go pop, because I can dance to it—it's more me." The album opens with its lead single, "...Baby One More Time", a teen pop and dance-pop song beginning with a three-note motif in the bass range of the piano. Its opening was compared to many other songs, such as "We Will Rock You" (1977), "Start Me Up" (1981), "These Words" (2004) and the theme song of the film Jaws due to the fact the track "makes its presence known in exactly one second". According to Blender, "...Baby One More Time" is composed of "wah-wah guitar lines and EKG-machine bass-slaps". Claudia Mitchell and Jacqueline Reid-Walsh, authors of Girl Culture: Studying Girl Culture: A Readers' Guide (2008), observed that the lyrics of the song "gesture toward [Spears] longing for the return of an ex-boyfriend." "(You Drive Me) Crazy" runs through a moderately slow dance beat, and has an R&B melody mixed with edgy synthesized instrumentals. "Sometimes" is a ballad, which Spears begins with the lines "You tell me you're in love with me / That you can't take your pretty eyes away from me / It's not that I don't wanna stay / But every time you come too close I move away". Stephen Thomas Erlewine of AllMusic noted the song has "a catchy hook and endearing melody, with a reminiscent euro-dance rhythm." "Soda Pop" draws influences from bubblegum pop and dancehall, and features background vocals from co-writer Mikey Bassie. Spears' vocals on the fifth track, "Born to Make You Happy" span more than an octave. Its lyrics allude to a relationship that a woman desires to repair, not quite understanding what went wrong, as she comes to realize that "I don't know how to live without your love / I was born to make you happy". "From the Bottom of My Broken Heart" is a sentimental slow-tempo teen pop ballad. "I Will Be There" is a pop rock song featuring a guitar riff similar to Natalie Imbruglia's "Torn" (1997), with a "rousing chorus about standing by your man (or a best friend or a house pet)", as noted by Kyle Anderson of MTV. "E-Mail My Heart" is a sensitive piano ballad on which Spears sings: "E-mail me back / And say our love will stay alive". The cover of Sonny & Cher's 1967 single "The Beat Goes On" is influenced by bossa nova and trip hop, and features a sound similar to spy film themes. Among the bonus tracks included on select editions of the album is a cover of J'Son's 1996 song "I'll Never Stop Loving You". Release and promotion Promotion for ...Baby One More Time began in May 1998, when Spears performed "...Baby One More Time", "Sometimes" and "You Got It All" at the Singapore Jazz Festival. Subsequently, she embarked on the L'Oréal-sponsored promotional tour titled L'Oreal Hair Zone Mall Tour, visiting malls and food courts across North America from June to August. In December, "...Baby One More Time" first showed up on MTV's and The Box's most-requested video charts. In the United States, ...Baby One More Time was originally set for an October 1998 release, but was pushed back to January 12, 1999, due to marketing issues, with its international release occurring within the following three months. Spears had appeared on Ricki Lake, The Howie Mandel Show, and was a presenter at the 1999 American Music Awards prior to the release. However, after hurting her knee in February, she rescheduled appearances on several shows, such as The Tonight Show with Jay Leno and Live with Regis and Kathie Lee. Additionally, she appeared on MTV Spring Break and on the hundredth episode of Nickelodeon's All That. After recovering, Spears embarked on another promotional schedule, appearing at the 1999 Kids' Choice Awards on May 1, Live with Regis and Kathie Lee on May 3, MTV's FANatic on May 12, and The Rosie O'Donnell Show on May 25. Outside the US, Spears visited the German shows Wetten, dass..? and Top of the Pops on June 25. She also went to the United Kingdom, making appearances on programmes such as This Morning, CD:UK and National Lottery. Spears visited the music variety show Hey! Hey! Hey! Music Champ in Japan, and performed at the Festival Bar in Italy. Spears was also featured on an episode of the ABC sitcom Sabrina, the Teenage Witch, in which she played herself. According to People, Spears was returning a favor to actress Melissa Joan Hart, who played a cameo role in Spears' music video for "(You Drive Me) Crazy". The episode aired on September 24. The same month, Spears performed on The Rosie O'Donnell Show on September 27, and visited Carson Daly on MTV's Total Request Live the following day. Spears also performed live with Joey McIntyre in the Disney Channel taped concert event titled Britney Spears & Joey McIntyre in Concert. In November, Spears performed "...Baby One More Time" and "(You Drive Me) Crazy" at the 1999 MTV Europe Music Awards. Promotion for the album continued in early 2000, when Spears performed at the 2000 American Music Awards, and also performed "From the Bottom of My Broken Heart" in a medley with "...Baby One More Time" at the 42nd Annual Grammy Awards. On March 5, 1999, it was reported that Spears was planning her first headlining tour. She announced that the tour would start in July. On May 12, Tommy Hilfiger was announced as the main tour sponsor, as Spears was being featured in the company's "AllStars" campaign at the time. On December 17, during the premiere of the music video of "From the Bottom of My Broken Heart" on Total Request Live, Spears called the show to announce the March 2000 US tour dates. The extension, entitled (You Drive Me) Crazy Tour, was considered a prelude to her future world tour, Oops!... I Did It Again Tour. The leg's main sponsor was Got Milk?, whose media director Peter Gardiner explained: "Britney is magic with teen-age girls, and that's an absolutely crucial target for milk". Spears shot an advertising campaign to be shown before her performances began. The secondary sponsor was Polaroid, who released I-Zone as the tour's official camera. Spears used the I-Zone onstage to take pictures of the audience and further promote the product. The show was divided into segments, separated by interludes, and ended with an encore. The set list consisted of songs from ...Baby One More Time and several covers. Some changes were made during the 2000 leg, with the covers replaced by songs from her second studio album Oops!... I Did It Again (2000). The tour received positive critical reception. During the tour, Spears was accused of lip synching, although she denied those claims. On April 20, the concert at Hilton Hawaiian Village in Honolulu, Hawaii, was taped. It was slightly altered from its tour incarnation and featured different costumes. On June 5, it was broadcast on Fox, airing several times during the year. On November 21, Jive Records released the video album Britney Spears: Live and More!, which included the Fox special. It was certified triple platinum by the Recording Industry Association of America (RIAA) for shipping 300,000 units. On August 14, 2017, 18 years after the release of ...Baby One More Time, it was announced that 2,500 pink-and-white-swirl copies of the album would be released on vinyl exclusively through Urban Outfitters on November 3. During the celebration of the 20th anniversary of Spears' debut single "...Baby One More Time", on October 19, 2018, Legacy Recordings announced the global release of the album on vinyl for November 23. Singles The title track was released as the lead single from ...Baby One More Time and Spears' debut single on September 28, 1998. It received generally favorable critical reviews, which mostly praised its composition. After its accompanying music video premiered in late November, the single attained worldwide success in early 1999, peaking atop the US Billboard Hot 100 and in most countries it charted in. It received numerous certifications around the world, and is one of the best-selling singles of all time, selling over ten million copies. The music video, directed by Nigel Dick, portrays Spears as a high school student who starts to sing and dance around the school, while watching her love interest from afar. In 2010, the video was voted the third most influential video in the history of pop music on Jam!. "Sometimes" was released as the second single from ...Baby One More Time on April 6, 1999. It achieved commercial success internationally, reaching number one in Belgium, the Netherlands and New Zealand. In the United States, however, it missed the top 20, peaking at number 21 on the Billboard Hot 100. The song's accompanying music video was directed by Nigel Dick. During rehearsals, on February 11, 1999, Spears injured her left knee and needed surgery. After recuperating in Kentwood, Louisiana, the video was filmed on April 9–10 at Paradise Cove in Malibu, California. It premiered on MTV's Total Request Live on May 6. In May 1999, Max Martin and Spears went to the Battery Studios in New York City to re-record the vocals of "(You Drive Me) Crazy", for a reproduced version subtitled "The Stop! Remix", which was going to be included on the original motion picture soundtrack for the film Drive Me Crazy (1999). The remix was subsequently released as the third single from ...Baby One More Time on August 24. It features the addition of a stanza in which Spears yells "Stop!", then all sound cutting out, followed by a transition, while omitting the lines "Lovin' you mean so much more, more than anything I ever loved before". The video was directed by Nigel Dick, and featured actors Melissa Joan Hart and Adrian Grenier. "Born to Make You Happy" was released as the fourth and final European single from ...Baby One More Time on December 6, 1999, to a mixed critical reception. A commercial success, it peaked within the top five in 11 countries and atop the UK Singles Chart. Its accompanying music video was directed by Bille Woodruff, and choreographed by Wade Robson. Despite its success in Europe, the song was never released as a single in the US. "From the Bottom of My Broken Heart" was released as the fourth and final North American and Oceanian single from ...Baby One More Time on December 14, 1999. The song received mixed critical reviews, which branded it a classic hit and competent single, despite considering it an unremarkable song referring only to kissing. It achieved moderate commercial success, peaking at number 14 on the US Billboard Hot 100. In Oceania, it peaked at number 37 in Australia and number 23 in New Zealand. It was certified platinum by the Recording Industry Association of America (RIAA) on March 28, 2000. The song's accompanying music video, directed by Gregory Dark, was released on December 17, 1999. It elicited controversy due to the fact that Dark had previously directed pornographic films. Critical reception ...Baby One More Time received mixed reviews from music critics upon its release. In a positive review, Stephen Thomas Erlewine of AllMusic gave the album four out of five stars. Paul Verna from Billboard considered the album "a top 40-ready workout filled with hook-laden songs from the same bag as the title cut". The Village Voice critic Robert Christgau highlighted the title track and "Soda Pop" while summing the album up as a "girl next door" version of Madonna. Kyle Anderson of MTV said he "was surprised in more ways than one" with his first listening of ...Baby One More Time, commenting he "expected there to be a lot of filler (there sort of is), though I didn't expect it to be as odd (at least sonically) as it ended up being. There has never been any mystery to why Spears became such a superstar, but these songs probably would have been huge even if Britney wore burlap sacks in all of her videos." Barry Walters of Rolling Stone gave the album two stars out of five, and compared the album's sound to early hits of Debbie Gibson, Mariah Carey and Samantha Fox. Walters also said that "while several Cherion-crafted kiddie-funk jams serve up beefy hooks, shameless schlock slowies, like 'E-Mail My Heart', is pure spam." An NME reviewer rated ...Baby One More Time one out of ten, saying that "we seem to have reached crisis point: pubescent pop is now so rife that 17-year-old Britney 'lizard-lounge' Spears is already halfway through her lucrative showbiz career". He also found the album premature, commenting: "hopefully, if she starts to live the wretched life that we all eventually do, her voice will show the scars, she'll stop looking so fucking smug, she'll find solace in drugs and we'll be all the happier for it. Now grow up, girl. Quick!" Amanda Murray of Sputnikmusic felt that "with the exception of the terrific title track, ...Baby One More Time is a collection of either competent pop songs underwhelmingly executed or underwhelmingly written pop songs competently executed."

Spears broke several records by doing so. The singer became the first new female artist to have a number-one single on the Billboard Hot 100 and number one album on the Billboard 200 at the same time; the first new artist (male or female) to have a single go to the number one spot the same week that the album debuted at number one; and the first new female artist to have the first single and first album at number one the same week. Spears is also the youngest female in Billboard history to have a simultaneous single and album at number one in the same week, and became the fifth artist under the age of 18 to top the Billboard 200. After fluctuating within the top five, the album went back to the summit in its fourth week. It sold over 500,000 copies within its first month, according to Nielsen SoundScan. Its fifth week became the album's highest-selling week with 229,000 copies sold, bringing the total to 804,000 copies. ...Baby One More Time spent a total of six non-consecutive weeks at number one, and sold over 1.8 million copies in the US within its first two months. In its 47th week on the Billboard 200, the album held strong at number three, reaching the ten-million sales mark in the country. The album was certified diamond by the Recording Industry Association of America (RIAA) on December 9, 1999, making then-18-year-old Spears the youngest artist to receive that certification, breaking the record held by Alanis Morissette, who was 21 when her album Jagged Little Pill (1995) was certified diamond. It became the 14th album since 1991 to sell over ten million copies in the US, and Spears became the best-selling female artist of 1999. ...Baby One More Time spent a total of 51 weeks within the top ten on the Billboard 200. It was the second best-selling album of 1999 in the US, only behind Millennium by the Backstreet Boys. The album has spent a total of 103 weeks on the Billboard 200. ...Baby One More Time landed at number three on BMG Music Club's all-time best-sellers list, selling 1.6 million units through the club. As of May 2020, it has sold 10.7 million copies in the US according to Nielsen SoundScan, with the BMG Music Club sales bringing its total to 12.3 million units. ...Baby One More Time debuted atop the Canadian Albums Chart, spending nine non-consecutive weeks at the summit. On December 12, 1999, the Canadian Recording Industry Association (CRIA) certified it diamond, for sales of over one million units. The album spent two weeks at number two on the European Top 100 Albums, and sold over four million copies across Europe, being certified quadruple platinum by the International Federation of the Phonographic Industry (IFPI). It peaked at number two on the UK Albums Chart, and has been certified quadruple platinum by the British Phonographic Industry (BPI). It peaked at number four in France, being certified double platinum by the Syndicat National de l'Édition Phonographique (SNEP). In addition, it has been certified triple gold in Germany, and decuple platinum (diamond) by the Polish Society of the Phonographic Industry (ZPAV). In Australia, it debuted at number nine on the ARIA Albums Chart, reaching number two nine weeks later. The album became the seventh highest-selling of 1999 in the country, and was certified quadruple platinum by the Australian Recording Industry Association (ARIA) the following year after shipping 280,000 copies to retailers. The album debuted at number three in New Zealand, later being certified triple platinum by the Recording Industry Association of New Zealand (RIANZ). Impact and legacy Spears was at the forefront of the female teen pop explosion starting in 1999 and extending through the 2000s, leading the pack of Christina Aguilera, Jessica Simpson, and Mandy Moore. All of these performers had been developing material in 1998, but the market changed dramatically in December 1998 when Spears' debut single and video were charting highly. RCA Records signed Aguilera and rushed her debut single to capitalize on Spears' success, producing the hit single "Genie in a Bottle" in May 1999 and Aguilera's eponymous debut studio album in August. Aguilera's album sold millions but not as many as ...Baby One More Time. Simpson consciously modeled her persona as more mature than Spears; her single "I Wanna Love You Forever" charted in September 1999, and her album Sweet Kisses followed shortly after. Moore's first single, "Candy", hit the airwaves a month before Simpson's single, but it did not perform as well on the charts; Moore was often seen as less accomplished than Spears and the others, coming in fourth of the "pop princesses". Fueling media stories about their competition for first place, Spears and Aguilera traded barbs but also compliments through the 2000s. The Daily Yomiuri reported that "critics have hailed her as the most gifted teenage pop idol for many years, but Spears has set her sights a little higher-she is aiming for the level of superstardom that has been achieved by Madonna and Janet Jackson." Rolling Stone wrote: "Britney Spears carries on the classic archetype of the rock & roll teen queen, the dungaree doll, the angel baby who just has to make a scene." Rami Yacoub who co-produced Spears's debut album with lyricist Max Martin commented: "I know from Denniz Pop and Max's previous productions, when we do songs, there's kind of a nasal thing. With N' Sync and the Backstreet Boys, we had to push for that mid-nasal voice. When Britney did that, she got this kind of raspy, sexy voice." Chuck Taylor of Billboard observed, "Spears has become a consummate performer, with snappy dance moves, a clearly real-albeit young-and funkdified voice ... "(You Drive Me) Crazy", her third single ... demonstrates Spears' own development, proving that the 17-year-old is finding her own vocal personality after so many months of steadfast practice." Stephen Thomas Erlewine of AllMusic referred to her music as a "blend of infectious, rap-inflected dance-pop and smooth balladry." Sputnikmusic writer Amanda Murray noted the album "offers a marker for Spears' progression as an artist, as a celebrity, and as a woman." In 2010, the album was included in the book 1001 Albums You Must Hear Before You Die. Spears became an international pop culture icon immediately after launching her recording career. Rolling Stone wrote: "One of the most controversial and successful female vocalists of the 21st century," she "spearheaded the rise of post-millennial teen pop ... Spears early on cultivated a mixture of innocence and experience that generated lots of cash". She is listed by the Guinness World Records as having the "Best-selling album by a teenage solo artist". Melissa Ruggieri of the Richmond Times-Dispatch reported, "She's also marked for being the best-selling teenage artist. Before she turned 20 in 2001, Spears sold more than 25 million albums worldwide". Barbara Ellen of The Observer reported: "Spears is famously one of the 'oldest' teenagers pop has ever produced, almost middle aged in terms of focus and determination. Many 19-year-olds haven't even started working by that age, whereas Britney, a former Mouseketeer, was that most unusual and volatile of American phenomena — a child with a full-time career. While other little girls were putting posters on their walls, Britney was wanting to be the poster on the wall. Whereas other children develop at their own pace, Britney was developing at a pace set by the ferociously competitive American entertainment industry". ...Baby One More Time is Spears' most commercially successful album to date, with worldwide sales of 25 million copies. It was ranked at number 41 on the all-time US Billboard 200 chart, and at number 16 on the Billboard 200 albums by women. Track listing Notes The very first pressings of the album feature a hidden spoken message by Spears after "The Beat Goes On". In it, Spears thanks fans and promotes the then-upcoming Backstreet Boys album, Millennium, with snippets of songs featured on the album. "Soda Pop" originally appeared on the soundtrack to the TV series Sabrina the Teenage Witch in 1998, in a slightly longer version. signifies a co-producer signifies an additional producer signifies a remixer Personnel Credits are adapted from the liner notes of ...Baby One More Time, except where noted.

Bulgaria

Bulgaria (; ), officially the Republic of Bulgaria, is a country in Southeast Europe. Located west of the Black Sea and south of the Danube river, Bulgaria is bordered by Greece and Turkey to the south, Serbia and North Macedonia to the west, and Romania to the north. It covers a territory of and is the 16th largest country in Europe. Sofia is the nation's capital and largest city; other major cities include Burgas, Plovdiv, and Varna. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asparuh, attacked from the lands of Old Great Bulgaria and permanently invaded the Balkans in the late 7th century. They established the First Bulgarian Empire, victoriously recognised by treaty in 681 AD by the Eastern Roman Empire. It dominated most of the Balkans and significantly influenced Slavic cultures by developing the Cyrillic script. The First Bulgarian Empire lasted until the early 11th century, when Byzantine emperor Basil II conquered and dismantled it. A successful Bulgarian revolt in 1185 established a Second Bulgarian Empire, which reached its apex under Ivan Asen II (1218–1241). After numerous exhausting wars and feudal strife, the empire disintegrated and in 1396 fell under Ottoman rule for nearly five centuries. The Russo-Turkish War of 1877–78 resulted in the formation of the third and current Bulgarian state. Many ethnic Bulgarians were left outside the new nation's borders, which stoked irredentist sentiments that led to several conflicts with its neighbours and alliances with Germany in both world wars. In 1946, Bulgaria came under the Soviet-led Eastern Bloc and became a socialist state. The ruling Communist Party gave up its monopoly on power after the revolutions of 1989 and allowed multiparty elections. Bulgaria then transitioned into a democracy and a market-based economy. Since adopting a democratic constitution in 1991, Bulgaria has been a unitary parliamentary republic composed of 28 provinces, with a high degree of political, administrative, and economic centralisation. Bulgaria is a developing country, with an upper-middle-income economy, ranking 68th in the Human Development Index. Its market economy is part of the European Single Market and is largely based on services, followed by industry—especially machine building and mining—and agriculture. A major socioeconomic issue in the country is widespread corruption, with Bulgaria being one of the most corrupt countries in the European Union. The country also faces a demographic crisis; its population peaked at 9 million in 1989, and has since decreased to 6.4 million as of 2023. Bulgaria is a member of the European Union, NATO, and the Council of Europe. It is also a founding member of the OSCE and has taken a seat on the United Nations Security Council three times. Etymology The name Bulgaria is derived from the Bulgars, a tribe of Turkic origin that founded the First Bulgarian Empire. Their name is not completely understood and is difficult to trace back earlier than the 4th century AD, but it is possibly derived from the Proto-Turkic word bulģha ("to mix", "shake", "stir") and its derivative bulgak ("revolt", "disorder"). The meaning may be further extended to "rebel", "incite" or "produce a state of disorder", and so, in the derivative, the "disturbers". Tribal groups in Inner Asia with phonologically close names were frequently described in similar terms, as the Buluoji, a component of the "Five Barbarian" groups, which during the 4th century were portrayed as both: a "mixed race" and "troublemakers". History Prehistory and Antiquity Neanderthal remains dating to around 150,000 years ago, or the Middle Paleolithic, are some of the earliest traces of human activity in the lands of modern Bulgaria. Remains from Homo sapiens found there are dated c. 47,000 years BP. This result represents the earliest arrival of modern humans in Europe. The Karanovo culture arose and was one of several Neolithic societies in the region that thrived on agriculture. The Copper Age Varna culture (fifth millennium BC) is credited with inventing gold metallurgy. The associated Varna Necropolis treasure contains the oldest golden jewellery in the world with an approximate age of over 6,000 years. The treasure has been valuable for understanding social hierarchy and stratification in the earliest European societies. The Thracians, one of the three primary ancestral groups of modern Bulgarians, appeared on the Balkan Peninsula some time before the 12th century BC. The Thracians excelled in metallurgy and gave the Greeks the Orphean and Dionysian cults, but remained tribal and stateless. The Persian Achaemenid Empire conquered parts of present-day Bulgaria (in particular eastern Bulgaria) in the 6th century BC and retained control over the region until 479 BC. The invasion became a catalyst for Thracian unity, and the bulk of their tribes united under king Teres to form the Odrysian kingdom in the 470s BC. It was weakened and vassalised by Philip II of Macedon in 341 BC, attacked by Celts in the 3rd century, and finally became a province of the Roman Empire in AD 45. By the end of the 1st century AD, Roman governance was established over the entire Balkan Peninsula and Christianity began spreading in the region around the 4th century. The Gothic Bible—the first Germanic language book—was created by Gothic bishop Ulfilas in what is today northern Bulgaria around 381. The region came under Byzantine control after the fall of Rome in 476. The Byzantines were engaged in prolonged warfare against Persia and could not defend their Balkan territories from barbarian incursions. This enabled the Slavs to enter the Balkan Peninsula as marauders, primarily through an area between the Danube River and the Balkan Mountains known as Moesia. Gradually, the interior of the peninsula became a country of the South Slavs, who lived under a democracy. The Slavs assimilated the partially Hellenised, Romanised, and Gothicised Thracians in the rural areas. First Bulgarian Empire Not long after the Slavic incursion, Moesia was once again invaded, this time by the Bulgars under Khan Asparukh. Their horde was a remnant of Old Great Bulgaria, an extinct tribal confederacy situated north of the Black Sea in what is now Ukraine and southern Russia. Asparukh attacked Byzantine territories in Moesia and conquered the Slavic tribes there in 680. A peace treaty with the Byzantine Empire was signed in 681, marking the foundation of the First Bulgarian Empire. The minority Bulgars formed a close-knit ruling caste. Succeeding rulers strengthened the Bulgarian state throughout the 8th and 9th centuries. Krum introduced a written code of law and checked a major Byzantine incursion at the Battle of Pliska, in which Byzantine emperor Nicephorus I was killed. Boris I abolished paganism in favour of Eastern Orthodox Christianity in 864. The conversion was followed by a Byzantine recognition of the Bulgarian church and the adoption of the Cyrillic alphabet, developed in the capital, Preslav. The common language, religion and script strengthened central authority and gradually fused the Slavs and Bulgars into a unified people speaking a single Slavic language. A golden age began during the 34-year rule of Simeon the Great, who oversaw the largest territorial expansion of the state. After Simeon's death, Bulgaria was weakened by wars with Magyars and Pechenegs and the spread of the Bogomil heresy. Preslav was seized by the Byzantine army in 971 after consecutive Rus' and Byzantine invasions. The empire briefly recovered from the attacks under Samuil, but this ended when Byzantine emperor Basil II defeated the Bulgarian army at Klyuch in 1014. Samuil died shortly after the battle, and by 1018 the Byzantines had conquered the First Bulgarian Empire. After the conquest, Basil II prevented revolts by retaining the rule of local nobility, integrating them in Byzantine bureaucracy and aristocracy, and relieving their lands of the obligation to pay taxes in gold, allowing tax in kind instead. The Bulgarian Patriarchate was reduced to an archbishopric, but retained its autocephalous status and its dioceses. Second Bulgarian Empire Byzantine domestic policies changed after Basil's death and a series of unsuccessful rebellions broke out, the largest being led by Peter Delyan. The empire's authority declined after a catastrophic military defeat at Manzikert against Seljuk invaders, and was further disturbed by the Crusades. This prevented Byzantine attempts at Hellenisation and created fertile ground for further revolt. In 1185, Asen dynasty nobles Ivan Asen I and Peter IV organised a major uprising and succeeded in re-establishing the Bulgarian state. Ivan Asen and Peter laid the foundations of the Second Bulgarian Empire with its capital at Tarnovo. Kaloyan, the third of the Asen monarchs, extended his dominion to Belgrade and Ohrid. He acknowledged the spiritual supremacy of the pope and received a royal crown from a papal legate. The empire reached its zenith under Ivan Asen II (1218–1241), when its borders expanded as far as the coast of Albania, Serbia and Epirus, while commerce and culture flourished. Ivan Asen's rule was also marked by a shift away from Rome in religious matters. The Asen dynasty became extinct in 1257. Internal conflicts and incessant Byzantine and Hungarian attacks followed, enabling the Mongols to establish suzerainty over the weakened Bulgarian state. In 1277, swineherd Ivaylo led a great peasant revolt that expelled the Mongols from Bulgaria and briefly made him emperor. He was overthrown in 1280 by the feudal landlords, whose factional conflicts caused the Second Bulgarian Empire to disintegrate into small feudal dominions by the 14th century. These fragmented rump states—two tsardoms at Vidin and Tarnovo and the Despotate of Dobrudzha—became easy prey for a new threat arriving from the Southeast: the Ottoman Turks. Ottoman rule The Ottomans were employed as mercenaries by the Byzantines in the 1340s but later became invaders in their own right. Sultan Murad I took Adrianople from the Byzantines in 1362; Sofia fell in 1382, followed by Shumen in 1388. The Ottomans completed their conquest of Bulgarian lands in 1393 when Tarnovo was sacked after a three-month siege and the Battle of Nicopolis which brought about the fall of the Vidin Tsardom in 1396. Sozopol was the last Bulgarian settlement to fall, in 1453. The Bulgarian nobility was subsequently eliminated and the peasantry was enserfed to Ottoman masters, while much of the educated clergy fled to other countries. Bulgarians were subjected to heavy taxes (including Devshirme, or blood tax), their culture was suppressed, and they experienced partial Islamisation. Ottoman authorities established a religious administrative community called the Rum Millet, which governed all Orthodox Christians regardless of their ethnicity. Most of the local population then gradually lost its distinct national consciousness, identifying only by its faith. The clergy remaining in some isolated monasteries kept their ethnic identity alive, enabling its survival in remote rural areas, and in the militant Catholic community in the northwest of the country. As Ottoman power began to wane, Habsburg Austria and Russia saw Bulgarian Christians as potential allies. The Austrians first backed an uprising in Tarnovo in 1598, then a second one in 1686, the Chiprovtsi Uprising in 1688 and finally Karposh's Rebellion in 1689. The Russian Empire also asserted itself as a protector of Christians in Ottoman lands with the Treaty of Küçük Kaynarca in 1774. The Western European Enlightenment in the 18th century influenced the initiation of a national awakening of Bulgaria. It restored national consciousness and provided an ideological basis for the liberation struggle, resulting in the 1876 April Uprising. Up to 30,000 Bulgarians were killed as Ottoman authorities put down the rebellion. The massacres prompted the Great Powers to take action. They convened the Constantinople Conference in 1876, but their decisions were rejected by the Ottomans. This allowed the Russian Empire to seek a military solution without risking confrontation with other Great Powers, as had happened in the Crimean War. In 1877, Russia declared war on the Ottomans and defeated them with the help of Bulgarian rebels, particularly during the crucial Battle of Shipka Pass which secured Russian control over the main road to Constantinople. Third Bulgarian state The Treaty of San Stefano was signed on 3 March 1878 by Russia and the Ottoman Empire. It was to set up an autonomous Bulgarian principality spanning Moesia, Macedonia and Thrace, roughly on the territories of the Second Bulgarian Empire, and this day is now a public holiday called National Liberation Day. The other Great Powers immediately rejected the treaty out of fear that such a large country in the Balkans might threaten their interests. It was superseded by the Treaty of Berlin, signed on 13 July. It provided for a much smaller state, the Principality of Bulgaria, only comprising Moesia and the region of Sofia, and leaving large populations of ethnic Bulgarians outside the new country. This significantly contributed to Bulgaria's militaristic foreign affairs approach during the first half of the 20th century. The Bulgarian principality won a war against Serbia and incorporated the semi-autonomous Ottoman territory of Eastern Rumelia in 1885, proclaiming itself an independent state on 5 October 1908. In the years following independence, Bulgaria increasingly militarised and was often referred to as "the Balkan Prussia". It became involved in three consecutive conflicts between 1912 and 1918—two Balkan Wars and World War I. After a disastrous defeat in the Second Balkan War, Bulgaria again found itself fighting on the losing side as a result of its alliance with the Central Powers in World War I. Despite fielding more than a quarter of its population in a 1,200,000-strong army and achieving several decisive victories at Doiran and Monastir, the country capitulated in 1918. The war resulted in significant territorial losses and a total of 87,500 soldiers killed. More than 253,000 refugees from the lost territories immigrated to Bulgaria from 1912 to 1929, placing additional strain on the already ruined national economy. The resulting political unrest led to the establishment of a royal authoritarian dictatorship by Tsar Boris III (1918–1943). Bulgaria entered World War II in 1941 as a member of the Axis but declined to participate in Operation Barbarossa and saved its Jewish population from deportation to concentration camps. The sudden death of Boris III in mid-1943 pushed the country into political turmoil as the war turned against Germany, and the communist guerrilla movement gained momentum. The government of Bogdan Filov subsequently failed to achieve peace with the Allies. Bulgaria did not comply with Soviet demands to expel German forces from its territory, resulting in a declaration of war and an invasion by the USSR in September 1944. The communist-dominated Fatherland Front took power, ended participation in the Axis and joined the Allied side until the war ended. Bulgaria suffered little war damage and the Soviet Union demanded no reparations. But all wartime territorial gains, with the notable exception of Southern Dobrudzha, were lost. The left-wing coup d'état of 9 September 1944 led to the abolition of the monarchy and the executions of some 1,000–3,000 dissidents, war criminals, and members of the former royal elite. But it was not until 1946 that a one-party people's republic was instituted following a referendum. It fell into the Soviet sphere of influence under the leadership of Georgi Dimitrov (1946–1949), who established a repressive, rapidly industrialising Stalinist state. By the mid-1950s, standards of living rose significantly and political repression eased. The Soviet-style planned economy saw some experimental market-oriented policies emerging under Todor Zhivkov (1954–1989). Compared to wartime levels, national GDP increased five-fold and per capita GDP quadrupled by the 1980s, although severe debt spikes took place in 1960, 1977 and 1980. Zhivkov's daughter Lyudmila bolstered national pride by promoting Bulgarian heritage, culture and arts worldwide. Facing declining birth rates among the ethnic Bulgarian majority, Zhivkov's government in 1984 forced the minority ethnic Turks to adopt Slavic names in an attempt to erase their identity and assimilate them. These policies resulted in the emigration of some 300,000 ethnic Turks to Turkey. The Communist Party was forced to give up its political monopoly on 10 November 1989 under the influence of the Revolutions of 1989. Zhivkov resigned and Bulgaria embarked on a transition to a parliamentary democracy. The first free elections in June 1990 were won by the Communist Party, now rebranded as the Bulgarian Socialist Party. A new constitution that provided for a relatively weak elected president and for a prime minister accountable to the legislature was adopted in July 1991. The new system initially failed to improve living standards or create economic growth—the average quality of life and economic performance remained lower than under communism well into the early 2000s. After 2001, economic, political and geopolitical conditions improved greatly, and Bulgaria achieved high Human Development status in 2003. It became a member of NATO in 2004 and participated in the War in Afghanistan. After several years of reforms, it joined the European Union and the single market in 2007, despite EU concerns over government corruption. Bulgaria hosted the 2018 Presidency of the Council of the European Union at the National Palace of Culture in Sofia. Geography Bulgaria is a middle-sized country situated in Southeastern Europe, in the east of the Balkans. Its territory covers an area of , while land borders with its five neighbouring countries run a total length of , and its coastline is long. Bulgaria's geographic coordinates are 43° N 25° E. The most notable topographical features of the country are the Danubian Plain, the Balkan Mountains, the Thracian Plain, and the Rila-Rhodope massif. The southern edge of the Danubian Plain slopes upward into the foothills of the Balkans, while the Danube defines the border with Romania. The Thracian Plain is roughly triangular, beginning southeast of Sofia and broadening as it reaches the Black Sea coast. The Balkan mountains run laterally through the middle of the country from west to east. The mountainous southwest has two distinct alpine type ranges—Rila and Pirin, which border the lower but more extensive Rhodope Mountains to the east, and various medium altitude mountains to west, northwest and south, like Vitosha, Osogovo and Belasitsa. Musala, at , is the highest point in both Bulgaria and the Balkans. The Black Sea coast is the country's lowest point. Plains occupy about one third of the territory, while plateaux and hills occupy 41%. Most rivers are short and with low water levels. The longest river located solely in Bulgarian territory, the Iskar, has a length of . The Struma and the Maritsa are two major rivers in the south. Climate Bulgaria has a varied and changeable climate, which results from being positioned at the meeting point of the Mediterranean, Oceanic and Continental air masses combined with the barrier effect of its mountains. Northern Bulgaria averages cooler, and registers more precipitation, than the regions south of the Balkan mountains. Temperature amplitudes vary significantly in different areas. The lowest recorded temperature is , while the highest is . Precipitation averages about per year, and varies from in Dobrudja to more than in the mountains. Continental air masses bring significant amounts of snowfall during winter. Considering its relatively small area, Bulgaria has variable and complex climate. The country occupies the southernmost part of the continental climatic zone, with small areas in the south falling within the Mediterranean climatic zone. The continental zone is predominant, because continental air masses flow easily into the unobstructed Danubian Plain. The continental influence, stronger during the winter, produces abundant snowfall; the Mediterranean influence increases during the second half of summer and produces hot and dry weather. Bulgaria is subdivided into five climatic zones: continental zone (Danubian Plain, Pre-Balkan and the higher valleys of the Transitional geomorphological region); transitional zone (Upper Thracian Plain, most of the Struma and Mesta valleys, the lower Sub-Balkan valleys); continental-Mediterranean zone (the southernmost areas of the Struma and Mesta valleys, the eastern Rhodope Mountains, Sakar and Strandzha); Black Sea zone along the coastline with an average length of 30–40 km inland; and alpine zone in the mountains above 1000 m altitude (central Balkan Mountains, Rila, Pirin, Vitosha, western Rhodope Mountains, etc.). Biodiversity and conservation The interaction of climatic, hydrological, geological and topographical conditions has produced a relatively wide variety of plant and animal species. Bulgaria's biodiversity, one of the richest in Europe, is conserved in three national parks, 11 nature parks, 10 biosphere reserves and 565 protected areas. Ninety-three of the 233 mammal species of Europe are found in Bulgaria, along with 49% of butterfly and 30% of vascular plant species. Overall, 41,493 plant and animal species are present. Larger mammals with sizable populations include deer (106,323 individuals), wild boar (88,948), golden jackal (47,293) and red fox (32,326). Partridges number some 328,000 individuals, making them the most widespread gamebird. A third of all nesting birds in Bulgaria can be found in Rila National Park, which also hosts Arctic and alpine species at high altitudes. Flora includes more than 3,800 vascular plant species of which 170 are endemic and 150 are considered endangered. A checklist of larger fungi in Bulgaria by the Institute of Botany identifies more than 1,500 species. More than 35% of the land area is covered by forests. In 1998, the Bulgarian government adopted the National Biological Diversity Conservation Strategy, a comprehensive programme seeking the preservation of local ecosystems, protection of endangered species and conservation of genetic resources. Bulgaria has some of the largest Natura 2000 areas in Europe covering 33.8% of its territory. It also achieved its Kyoto Protocol objective of reducing carbon dioxide emissions by 30% from 1990 to 2009. Bulgaria ranks 30th in the 2018 Environmental Performance Index, but scores low on air quality. Particulate levels are the highest in Europe, especially in urban areas affected by automobile traffic and coal-based power stations. One of these, the lignite-fired Maritsa Iztok-2 station, is causing the highest damage to health and the environment in the European Union. Pesticide use in agriculture and antiquated industrial sewage systems produce extensive soil and water pollution. Water quality began to improve in 1998 and has maintained a trend of moderate improvement. Over 75% of surface rivers meet European standards for good quality. Politics Bulgaria is a parliamentary democracy where the prime minister is the head of government and the most powerful executive position. The political system has three branches—legislative, executive and judicial, with universal suffrage for citizens at least 18 years old. The Constitution also provides possibilities of direct democracy, namely petitions and national referendums. Elections are supervised by an independent Central Election Commission that includes members from all major political parties. Parties must register with the commission prior to participating in a national election. Normally, the prime minister-elect is the leader of the party receiving the most votes in parliamentary elections, although this is not always the case. Unlike the prime minister, presidential domestic power is more limited. The directly elected president serves as head of state and commander-in-chief of the armed forces, and has the authority to return a bill for further debate, although the parliament can override the presidential veto by a simple majority vote. Political parties gather in the National Assembly, a body of 240 deputies elected to four-year terms by direct popular vote. The National Assembly has the power to enact laws, approve the budget, schedule presidential elections, select and dismiss the prime minister and other ministers, declare war, deploy troops abroad, and ratify international treaties and agreements. Overall, Bulgaria displays a pattern of unstable governments. Boyko Borisov, the leader of the centre-right, pro-EU party GERB, served three terms as prime minister between 2009 and 2021. It won the 2009 general election and formed a minority government, which resigned in February 2013 after nationwide protests over the low living standards, corruption and the perceived failure of the democratic system. The subsequent snap elections in May resulted in a narrow win for GERB, but the Bulgarian Socialist Party eventually formed a government led by Plamen Oresharski after Borisov failed to secure parliamentary support. The Oresharski government resigned in July 2014 amid continuing large-scale protests. The October 2014 elections resulted in a third GERB victory. Borisov formed a coalition with several right-wing parties, but resigned again after the candidate backed by his party failed to win the 2016 Presidential election. The March 2017 snap election was again won by GERB, but with 95 seats in Parliament. They formed a coalition with the far-right United Patriots, who held 27 seats. Borisov's last cabinet saw a dramatic decrease in freedom of the press, and a number of corruption revelations that triggered yet another wave of mass protests in 2020. GERB came out first in the regular April 2021 election, but with its weakest result so far. All other parties refused to form a government, and after a brief deadlock, another election was called for July 2021. It too failed to break the stalemate, as no political party was able to form a coalition government. In April 2023, because of the political deadlock, Bulgaria held its fifth parliamentary election since April 2021. GERB was the biggest, winning 69 seats. The bloc led by We Continue the Change won 64 seats in the 240-seat parliament. In June 2023, Prime Minister Nikolai Denkov formed a new coalition between We Continue The Change and GERB. According to the coalition agreement, Denkov will lead the government for the first nine months. He will be succeeded by former European Commissioner, Mariya Gabriel, of the GERB party. She will take over as Prime Minister after nine months. Freedom House has reported a continuing deterioration of democratic governance after 2009, citing reduced media independence, stalled reforms, abuse of authority at the highest level and increased dependence of local administrations on the central government. Bulgaria is still listed as "Free", with a political system designated as a semi-consolidated democracy, albeit with deteriorating scores. The Democracy Index defines it as a "Flawed democracy". A 2018 survey by the Institute for Economics and Peace reported that less than 15% of respondents considered elections to be fair. Legal system Bulgaria has a civil law legal system. The judiciary is overseen by the Ministry of Justice. The Supreme Administrative Court and the Supreme Court of Cassation are the highest courts of appeal and oversee the application of laws in subordinate courts. The Supreme Judicial Council manages the system and appoints judges. The legal system is regarded by both domestic and international observers as one of Europe's most inefficient due to a pervasive lack of transparency and corruption. Law enforcement is carried out by organisations mainly subordinate to the Ministry of the Interior. The General Directorate of National Police (GDNP) combats general crime and maintains public order. GDNP fields 26,578 police officers in its local and national sections. The bulk of criminal cases are transport-related, followed by theft and drug-related crime; homicide rates are low. The Ministry of the Interior also heads the Border Police Service and the National Gendarmerie—a specialised branch for anti-terrorist activity, crisis management and riot control. Counterintelligence and national security are the responsibility of the State Agency for National Security. Administrative divisions Bulgaria is a unitary state. Since the 1880s, the number of territorial management units has varied from seven to 26. Between 1987 and 1999, the administrative structure consisted of nine provinces (oblasti, singular oblast). A new administrative structure was adopted in parallel with the decentralisation of the economic system. It includes 27 provinces and a metropolitan capital province (Sofia-Grad). All areas take their names from their respective capital cities. The provinces are subdivided into 265 municipalities. Municipalities are run by mayors, who are elected to four-year terms, and by directly elected municipal councils. Bulgaria is a highly centralised state where the Council of Ministers directly appoints regional governors and all provinces and municipalities are heavily dependent on it for funding. Foreign relations Bulgaria became a member of the United Nations in 1955 and since 1966 has been a non-permanent member of the Security Council three times, most recently from 2002 to 2003. It was also among the founding nations of the Organization for Security and Co-operation in Europe (OSCE) in 1975. Euro-Atlantic integration has been a priority since the fall of communism, although the communist leadership also had aspirations of leaving the Warsaw Pact and joining the European Communities by 1987. Bulgaria signed the European Union Treaty of Accession on 25 April 2005, and became a full member of the European Union on 1 January 2007. In addition, it has a tripartite economic and diplomatic collaboration with Romania and Greece, good ties with China and Vietnam and a historical relationship with Russia. Bulgaria deployed significant numbers of both civilian and military advisors in Soviet-allied countries like Nicaragua and Libya during the Cold War. The first deployment of foreign troops on Bulgarian soil since World War II occurred in 2001, when the country hosted six KC-135 Stratotanker aircraft and 200 support personnel for the war effort in Afghanistan. International military relations were further expanded with accession to NATO in March 2004 and the US-Bulgarian Defence Cooperation Agreement signed in April 2006. Bezmer and Graf Ignatievo air bases, the Novo Selo training range, and a logistics centre in Aytos subsequently became joint military training facilities cooperatively used by the United States and Bulgarian militaries. Despite its active international defence collaborations, Bulgaria ranks as among the most peaceful countries globally, tying 6th alongside Iceland regarding domestic and international conflicts, and 26th on average in the Global Peace Index. Military The Bulgarian Armed Forces are the military of Bulgaria and they are composed of land forces, navy and an air force. The Armed Forces have 36,950 active troops, supplemented by 3,000 reservists. The land forces consist of two mechanised brigades and eight independent regiments and battalions; the air force operates 106 aircraft and air defence systems across six air bases, and the navy operates various ships, helicopters and coastal defence weapons. Military inventory mainly consists of Soviet equipment like Mikoyan MiG-29 and Sukhoi Su-25 jets, S-300PT air defence systems and SS-21 Scarab short-range ballistic missiles.Bulgaria's Armed Forces are modernizing with F-16 Block 70 fighter jets, new Multi-Purpose corvettes and other modern NATO-standard equipment. Bulgaria is in the process of buying new US built Stryker vehicles, new 155 mm Self-propelled howitzers,new 3D Early-warning radars, new Surface-to-air missiles and more. Economy Bulgaria has an open, upper middle income range market economy where the private sector accounts for more than 70% of GDP. From a largely agricultural country with a predominantly rural population in 1948, by the 1980s Bulgaria had transformed into an industrial economy, with scientific and technological research at the top of its budgetary expenditure priorities. The loss of COMECON markets in 1990 and the subsequent "shock therapy" of the planned system caused a steep decline in industrial and agricultural production, ultimately followed by an economic collapse in 1997. The economy largely recovered during a period of rapid growth several years later, but the average salary of 1,036 leva ($615) per month remains the lowest in the EU. More than a fifth of the labour force work for a minimum wage of $1.16 per hour. A balanced budget was achieved in 2003 and the country began running a surplus the following year. Expenditures amounted to $21.15 billion and revenues were $21.67 billion in 2017. Most government spending on institutions is earmarked for security. The ministries of defence, the interior and justice are allocated the largest share of the annual government budget, whereas those responsible for the environment, tourism and energy receive the least funding. Taxes form the bulk of government revenue at 30% of GDP. Bulgaria has some of the lowest corporate income tax rates in the EU at a flat 10% rate. The tax system is two-tier. Value added tax, excise duties, corporate and personal income tax are national, whereas real estate, inheritance, and vehicle taxes are levied by local authorities. Strong economic performance in the early 2000s reduced government debt from 79.6% in 1998 to 14.1% in 2008. It has since increased to 28.7% of GDP by 2016, but remains the third lowest in the EU. The Yugozapaden planning area is the most developed region with a per capita gross domestic product (PPP) of $29,816 in 2018. It includes the capital city and the surrounding Sofia Province, which alone generate 42% of national gross domestic product despite hosting only 22% of the population. GDP per capita (in PPS) and the cost of living in 2019 stood at 53 and 52.8% of the EU average (100%), respectively. National PPP GDP was estimated at $143.1 billion in 2016, with a per capita value of $20,116. Economic growth statistics take into account illegal transactions from the informal economy, which is the largest in the EU as a percentage of economic output. The Bulgarian National Bank issues the national currency, lev, which is pegged to the euro at a rate of 1.95583 levа per euro. After several consecutive years of high growth, repercussions of the financial crisis of 2007–2008 resulted in a 3.6% contraction of GDP in 2009 and increased unemployment. Positive growth was restored in 2010 but intercompany debt exceeded $59 billion, meaning that 60% of all Bulgarian companies were mutually indebted. By 2012, it had increased to $97 billion, or 227% of GDP. The government implemented strict austerity measures with IMF and EU encouragement to some positive fiscal results, but the social consequences of these measures, such as increased income inequality and accelerated outward migration, have been "catastrophic" according to the International Trade Union Confederation. Siphoning of public funds to the families and relatives of politicians from incumbent parties has resulted in fiscal and welfare losses to society. Bulgaria ranks 71st in the Corruption Perceptions Index and experiences the worst levels of corruption in the European Union, a phenomenon that remains a source of profound public discontent. Along with organised crime, corruption has resulted in a rejection of the country's Schengen Area application and withdrawal of foreign investment. Government officials reportedly engage in embezzlement, influence trading, government procurement violations and bribery with impunity. Government procurement in particular is a critical area in corruption risk. An estimated 10 billion leva ($5.99 billion) of state budget and European cohesion funds are spent on public tenders each year; nearly 14 billion ($8.38 billion) were spent on public contracts in 2017 alone. A large share of these contracts are awarded to a few politically connected companies amid widespread irregularities, procedure violations and tailor-made award criteria. Despite repeated criticism from the European Commission, EU institutions refrain from taking measures against Bulgaria because it supports Brussels on a number of issues, unlike Poland or Hungary. Structure and sectors The labour force is 3.36 million people, of whom 6.8% are employed in agriculture, 26.6% in industry and 66.6% in the services sector. Extraction of metals and minerals, production of chemicals, machine building, steel, biotechnology, tobacco, food processing and petroleum refining are among the major industrial activities. Mining alone employs 24,000 people and generates about 5% of the country's GDP; the number of employed in all mining-related industries is 120,000. Bulgaria is Europe's fifth-largest coal producer. Local deposits of coal, iron, copper and lead are vital for the manufacturing and energy sectors. The main destinations of Bulgarian exports outside the EU are Turkey, China and the United States, while Russia and Turkey are by far the largest import partners. Most of the exports are manufactured goods, machinery, chemicals, fuel products and food. Two-thirds of food and agricultural exports go to OECD countries. Although cereal and vegetable output dropped by 40% between 1990 and 2008, output in grains has since increased, and the 2016–2017 season registered the biggest grain output in a decade. Maize, barley, oats and rice are also grown. Quality Oriental tobacco is a significant industrial crop. Bulgaria is also the largest producer globally of lavender and rose oil, both widely used in fragrances. Within the services sector, tourism is a significant contributor to economic growth. Sofia, Plovdiv, Veliko Tarnovo, coastal resorts Albena, Golden Sands and Sunny Beach and winter resorts Bansko, Pamporovo and Borovets are some of the locations most visited by tourists. Most visitors are Romanian, Turkish, Greek and German. Tourism is additionally encouraged through the 100 Tourist Sites system. Science and technology Spending on research and development amounts to 0.78% of GDP, and the bulk of public R&D funding goes to the Bulgarian Academy of Sciences (BAS). Private businesses accounted for more than 73% of R&D expenditures and employed 42% of Bulgaria's 22,000 researchers in 2015. The same year, Bulgaria ranked 39th out of 50 countries in the Bloomberg Innovation Index, the highest score being in education (24th) and the lowest in value-added manufacturing (48th). Bulgaria was ranked 38th in the Global Innovation Index in 2023. Chronic government underinvestment in research since 1990 has forced many professionals in science and engineering to leave Bulgaria. Despite the lack of funding, research in chemistry, materials science and physics remains strong. Antarctic research is actively carried out through the St. Kliment Ohridski Base on Livingston Island in Western Antarctica. The information and communication technologies (ICT) sector generates three per cent of economic output and employs 40,000 to 51,000 software engineers. Bulgaria was known as a "Communist Silicon Valley" during the Soviet era due to its key role in COMECON computing technology production. A concerted effort by the communist government to teach computing and IT skills in schools also indirectly made Bulgaria a major source of computer viruses in the 1980s and 90s. The country is a regional leader in high performance computing: it operates Avitohol, the most powerful supercomputer in Southeast Europe, and will host one of the eight petascale EuroHPC supercomputers. Bulgaria has made numerous contributions to space exploration. These include two scientific satellites, more than 200 payloads and 300 experiments in Earth orbit, as well as two cosmonauts since 1971. Bulgaria was the first country to grow wheat and vegetables in space with its Svet greenhouses on the Mir space station. It was involved in the development of the Granat gamma-ray observatory and the Vega program, particularly in modelling trajectories and guidance algorithms for both Vega probes. Bulgarian instruments have been used in the exploration of Mars, including a spectrometer that took the first high quality spectroscopic images of Martian moon Phobos with the Phobos 2 probe. Cosmic radiation en route to and around the planet has been mapped by Liulin-ML dosimeters on the ExoMars TGO. Variants of these instruments have also been fitted on the International Space Station and the Chandrayaan-1 lunar probe. Another lunar mission, SpaceIL's Beresheet, was also equipped with a Bulgarian-manufactured imaging payload. Bulgaria's first geostationary communications satellite—BulgariaSat-1—was launched by SpaceX in 2017. Infrastructure Telephone services are widely available, and a central digital trunk line connects most regions. Vivacom (BTC) serves more than 90% of fixed lines and is one of the three operators providing mobile services, along with A1 and Telenor. Internet penetration stood at 69.2% of the population aged 16–74 and 78.9% of households in 2020. Bulgaria's strategic geographic location and well-developed energy sector make it a key European energy centre despite its lack of significant fossil fuel deposits. Thermal power plants generate 48.9% of electricity, followed by nuclear power from the Kozloduy reactors (34.8%) and renewable sources (16.3%). Equipment for a second nuclear power station at Belene has been acquired, but the fate of the project remains uncertain. Installed capacity amounts to 12,668 MW, allowing Bulgaria to exceed domestic demand and export energy. The national road network has a total length of , of which are paved. Railroads are a major mode of freight transportation, although highways carry a progressively larger share of freight. Bulgaria has of railway track, with rail links available to Romania, Turkey, Greece, and Serbia, and express trains serving direct routes to Kyiv, Minsk, Moscow and Saint Petersburg. Sofia is the country's air travel hub, while Varna and Burgas are the principal maritime trade ports. Demographics According to the government's official 2022 estimate, the population of Bulgaria consists of 6,447,710 people, down from 6,519,789 according to the last official census in 2021. The majority of the population, 72.5%, reside in urban areas. , Sofia is the most populated urban centre with 1,241,675 people, followed by Plovdiv (346,893), Varna (336,505), Burgas (202,434) and Ruse (142,902). Bulgarians are the main ethnic group and constitute 84.6% of the population. Turkish and Roma minorities account for 8.4 and 4.4%, respectively; some 40 smaller minorities account for 1.3%, and 1.3% do not self-identify with an ethnic group. The Roma minority is usually underestimated in census data and may represent up to 11% of the population. Population density is 55-60 per square kilometre (ultimo 2023), almost half the European Union average. Bulgaria is in a state of demographic crisis. It has had negative population growth since 1989, when the post-Cold War economic collapse caused a long-lasting emigration wave. Some 937,000 to 1,200,000 people—mostly young adults—had left the country by 2005. The majority of children are born to unmarried women. In 2018, the average total fertility rate (TFR) in Bulgaria was 1.56 children per woman, below the replacement rate of 2.1 and considerably below the historical high of 5.83 children per woman in 1905. Bulgaria thus has one of the oldest populations in the world, with an average age of 43 years. Furthermore, a third of all households consist of only one person and 75.5% of families do not have children under the age of 16. The resulting birth rates are among the lowest in the world while death rates are among the highest. Bulgaria scores high in gender equality, ranking 18th in the 2018 Global Gender Gap Report. Although women's suffrage was enabled relatively late, in 1937, women today have equal political rights, high workforce participation and legally mandated equal pay. In 2021, market research agency Reboot Online ranked Bulgaria as the best European country for women to work. Bulgaria has the highest ratio of female ICT researchers in the EU, as well as the second-highest ratio of females in the technology sector at 44.6% of the workforce. High levels of female participation are a legacy of the Socialist era. Largest cities Health High death rates result from a combination of an ageing population, high numbers of people at risk of poverty, and a weak healthcare system. Over 80% of deaths are due to cancer and cardiovascular conditions; nearly a fifth of those are avoidable. Although healthcare in Bulgaria is nominally universal, out-of-pocket expenses account for nearly half of all healthcare spending, significantly limiting access to medical care. Other problems disrupting care provision are the emigration of doctors due to low wages, understaffed and under-equipped regional hospitals, supply shortages and frequent changes to the basic service package for those insured. The 2018 Bloomberg Health Care Efficiency Index ranked Bulgaria last out of 56 countries. Average life expectancy is 74.8 years, compared with an EU average of 80.99 and a world average of 72.38. Education Public expenditures for education are far below the European Union average as well. Educational standards were once high, but have declined significantly since the early 2000s. Bulgarian students were among the highest-scoring in the world in terms of reading in 2001, performing better than their Canadian and German counterparts; by 2006, scores in reading, math and science had dropped. By 2018, Programme for International Student Assessment studies found 47% of pupils in the 9th grade to be functionally illiterate in reading and natural sciences. Average basic literacy stands high at 98.4% with no significant difference between sexes. The Ministry of Education and Science partially funds public schools, colleges and universities, sets criteria for textbooks and oversees the publishing process. Education in primary and secondary public schools is free and compulsory. The process spans 12 grades, in which grades one through eight are primary and nine through twelve are secondary level. Higher education consists of a 4-year bachelor degree and a 1-year master's degree. Bulgaria's highest-ranked higher education institution is Sofia University. Language Bulgarian is the only language with official status. It belongs to the Slavic group of languages but has a number of grammatical peculiarities, that set it apart from other Slavic languages: these include a complex verbal morphology (which also codes for distinctions in evidentiality), the absence of noun cases and infinitives, and the use of a suffixed definite article. Religion Bulgaria is a secular state with guaranteed freedom of religion by constitution, but Eastern Orthodox Christianity is designated as the traditional religion of the country. Approximately two-thirds of Bulgarians identify as Eastern Orthodox Christians. The Bulgarian Orthodox Church was the first church apart from the Four Ancient Patriarchates—in Constantinople, Alexandria, Antioch and Jerusalem—and the first national church to gain autocephalous status in 927 AD. The Bulgarian Patriarchate has 12 dioceses and over 2,000 priests. Muslims are the second-largest religious community and constitute approx. 10% of Bulgaria's overall religious makeup. A 2011 survey of 850 Muslims in Bulgaria found 30% self-professing as deeply religious and 50% as just religious. According to the study, some religious teachings, like Islamic funeral, have been traditionally incorporated and are widely practiced while other major ones are less observed, such as the Muslim prayer or abstaining from drinking alcohol, eating pork, and cohabitation. Other important religions include Roman Catholicism and Judaism, whose history in Bulgaria dates back to the early Middle Ages, the Armenian Apostolic Church, as well as various Protestant denominations, all of which stand for around 2% of Bulgaria's population. An ever increasing number of Bulgarians are either irreligious or unaffiliated with any religion, a percentage that has been growing rapidly over the past 20 years, from 3.9% in 2001, through 9.3% in 2011 and all the way to 15.9% in 2021. 1Data borrowed from administrative sources. Culture Contemporary Bulgarian culture blends the formal culture that helped forge a national consciousness towards the end of Ottoman rule with millennia-old folk traditions. An essential element of Bulgarian folklore is fire, used to banish evil spirits and illnesses. Many of these are personified as witches, whereas other creatures like zmey and samodiva (veela) are either benevolent guardians or ambivalent tricksters. Some rituals against evil spirits have survived and are still practised, most notably kukeri and survakari. Martenitsa is also widely celebrated. Nestinarstvo, a ritual fire-dance of Thracian origin, is included in the list of UNESCO Intangible Cultural Heritage. Nine historical and natural objects are UNESCO World Heritage Sites: Pirin National Park, Sreburna Nature Reserve, the Madara Rider, the Thracian tombs in Sveshtari and Kazanlak, the Rila Monastery, the Boyana Church, the Rock-hewn Churches of Ivanovo and the ancient city of Nesebar. The Rila Monastery was established by Saint John of Rila, Bulgaria's patron saint, whose life has been the subject of numerous literary accounts since Medieval times. The establishment of the Preslav and Ohrid literary schools in the 10th century is associated with a golden period in Bulgarian literature during the Middle Ages. The schools' emphasis on Christian scriptures made the Bulgarian Empire a centre of Slavic culture, bringing Slavs under the influence of Christianity and providing them with a written language. Its alphabet, Cyrillic script, was developed by the Preslav Literary School. The Tarnovo Literary School, on the other hand, is associated with a Silver age of literature defined by high-quality manuscripts on historical or mystical themes under the Asen and Shishman dynasties. Many literary and artistic masterpieces were destroyed by the Ottoman conquerors, and artistic activities did not re-emerge until the National Revival in the 19th century. The enormous body of work of Ivan Vazov (1850–1921) covered every genre and touched upon every facet of Bulgarian society, bridging pre-Liberation works with literature of the newly established state. Notable later works are Bay Ganyo by Aleko Konstantinov, the Nietzschean poetry of Pencho Slaveykov, the Symbolist poetry of Peyo Yavorov and Dimcho Debelyanov, the Marxist-inspired works of Geo Milev and Nikola Vaptsarov, and the Socialist realism novels of Dimitar Dimov and Dimitar Talev. Tzvetan Todorov is a notable contemporary author, while Bulgarian-born Elias Canetti was awarded the Nobel Prize in Literature in 1981. А religious visual arts heritage includes frescoes, murals and icons, many produced by the medieval Tarnovo Artistic School. Like literature, it was not until the National Revival when Bulgarian visual arts began to reemerge. Zahari Zograf was a pioneer of the visual arts in the pre-Liberation era. After the Liberation, Ivan Mrkvička, Anton Mitov, Vladimir Dimitrov, Tsanko Lavrenov and Zlatyu Boyadzhiev introduced newer styles and substance, depicting scenery from Bulgarian villages, old towns and historical subjects. Christo is the most famous Bulgarian artist of the 21st century, known for his outdoor installations. Folk music is by far the most extensive traditional art and has slowly developed throughout the ages as a fusion of Far Eastern, Oriental, medieval Eastern Orthodox and standard Western European tonalities and modes. Bulgarian folk music has a distinctive sound and uses a wide range of traditional instruments, such as gadulka, gaida, kaval and tupan. A distinguishing feature is extended rhythmical time, which has no equivalent in the rest of European music. The State Television Female Vocal Choir won a Grammy Award in 1990 for its performances of Bulgarian folk music. Written musical composition can be traced back to the works of Yoan Kukuzel (–1360), but modern classical music began with Emanuil Manolov, who composed the first Bulgarian opera in 1890. Pancho Vladigerov and Petko Staynov further enriched symphony, ballet and opera, which singers Ghena Dimitrova, Boris Christoff, Ljuba Welitsch and Nicolai Ghiaurov elevated to a world-class level. Bulgarian performers have gained acclaim in other genres like electropop (Mira Aroyo), jazz (Milcho Leviev) and blends of jazz and folk (Ivo Papazov). The Bulgarian National Radio, bTV and daily newspapers Trud, and 24 Chasa are some of the largest national media outlets. Bulgarian media were described as generally unbiased in their reporting in the early 2000s and print media had no legal restrictions. Since then, freedom of the press has deteriorated to the point where Bulgaria scores 111th globally in the World Press Freedom Index, lower than all European Union members and membership candidate states. The government has diverted EU funds to sympathetic media outlets and bribed others to be less critical on problematic topics, while attacks against individual journalists have increased. Collusion between politicians, oligarchs and the media is widespread. Bulgarian cuisine is similar to that of other Balkan countries and demonstrates strong Turkish and Greek influences. Yogurt, lukanka, banitsa, shopska salad, lyutenitsa and kozunak are among the best-known local foods. Meat consumption is lower than the European average, given a cultural preference for a large variety of salads. Bulgaria was the world's second-largest wine exporter until 1989, but has since lost that position. The 2016 harvest yielded 128 million litres of wine, of which 62 million was exported mainly to Romania, Poland and Russia. Mavrud, Rubin, Shiroka melnishka, Dimiat and Cherven Misket are the typical grapes used in Bulgarian wine. Rakia is a traditional fruit brandy that was consumed in Bulgaria as early as the 14th century. Sports Bulgaria appeared at the first modern Olympic games in 1896, when it was represented by gymnast Charles Champaud. Since then, Bulgarian athletes have won 55 gold, 90 silver, and 85 bronze medals, ranking 25th in the all-time medal table. Weight-lifting is a signature sport of Bulgaria. Coach Ivan Abadzhiev developed innovative training practices that have produced many Bulgarian world and Olympic champions in weight-lifting since the 1980s. Bulgarian athletes have also excelled in wrestling, boxing, gymnastics, volleyball and tennis. Stefka Kostadinova is the reigning world record holder in the women's high jump at , achieved during the 1987 World Championships. Grigor Dimitrov is the first Bulgarian tennis player in the Top 3 ATP rankings. Football is the most popular sport in the country by a substantial margin. The national football team's best performance was a semi-final at the 1994 FIFA World Cup, when the squad was spearheaded by forward Hristo Stoichkov. Stoichkov is the most successful Bulgarian player of all time; he was awarded the Golden Boot and the Golden Ball and was considered one of the best in the world while playing for FC Barcelona in the 1990s. CSKA and Levski, both based in Sofia, are the most successful clubs domestically and long-standing rivals. Ludogorets is remarkable for having advanced from the local fourth division to the 2014–15 UEFA Champions League group stage in a mere nine years. Placed 39th in 2018, it is Bulgaria's highest-ranked club in UEFA. See also Outline of Bulgaria Explanatory notes References Bibliography External links Bulgaria at UCB Libraries GovPubs.

Bryozoa

Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (Aethozooides and Monobryozoon); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups were noted to be very different internally. The new group was given the name "Entoprocta", while the original Bryozoa were called "Ectoprocta". Disagreements about terminology persisted well into the 20th century, but "Bryozoa" is now the generally accepted term. Colonies take a variety of forms, including fans, bushes and sheets. Single animals, called zooids, live throughout the colony and are not fully independent. These individuals can have unique and diverse functions. All colonies have "autozooids", which are responsible for feeding, excretion, and supplying nutrients to the colony through diverse channels. Some classes have specialist zooids like hatcheries for fertilized eggs, colonial defence structures, and root-like attachment structures. Cheilostomata is the most diverse order of bryozoan, possibly because its members have the widest range of specialist zooids. They have mineralized exoskeletons and form single-layered sheets which encrust over surfaces, and some colonies can creep very slowly by using spiny defensive zooids as legs. Each zooid consists of a "cystid", which provides the body wall and produces the exoskeleton, and a "polypide", which holds the organs. Zooids have no special excretory organs, and autozooids' polypides are scrapped when they become overloaded with waste products; usually the body wall then grows a replacement polypide. Their gut is U-shaped, with the mouth inside the crown of tentacles and the anus outside it. Zooids of all the freshwater species are simultaneous hermaphrodites. Although those of many marine species function first as males and then as females, their colonies always contain a combination of zooids that are in their male and female stages. All species emit sperm into the water. Some also release ova into the water, while others capture sperm via their tentacles to fertilize their ova internally. In some species the larvae have large yolks, go to feed, and quickly settle on a surface. Others produce larvae that have little yolk but swim and feed for a few days before settling. After settling, all larvae undergo a radical metamorphosis that destroys and rebuilds almost all the internal tissues. Freshwater species also produce statoblasts that lie dormant until conditions are favorable, which enables a colony's lineage to survive even if severe conditions kill the mother colony. Predators of marine bryozoans include sea slugs (nudibranchs), fish, sea urchins, pycnogonids, crustaceans, mites and starfish. Freshwater bryozoans are preyed on by snails, insects, and fish. In Thailand, many populations of one freshwater species have been wiped out by an introduced species of snail. A fast-growing invasive bryozoan off the northeast and northwest coasts of the US has reduced kelp forests so much that it has affected local fish and invertebrate populations. Bryozoans have spread diseases to fish farms and fishermen. Chemicals extracted from a marine bryozoan species have been investigated for treatment of cancer and Alzheimer's disease, but analyses have not been encouraging. Mineralized skeletons of bryozoans first appear in rocks from the Early Ordovician period, making it the last major phylum to appear in the fossil record. This has led researchers to suspect that bryozoans arose earlier but were initially unmineralized, and may have differed significantly from fossilized and modern forms. In 2021, some research suggested Protomelission, a genus known from the Cambrian period, could be an example of an early bryozoan, but later research suggested that this taxon may instead represent a dasyclad alga. Early fossils are mainly of erect forms, but encrusting forms gradually became dominant. It is uncertain whether the phylum is monophyletic. Bryozoans' evolutionary relationships to other phyla are also unclear, partly because scientists' view of the family tree of animals is mainly influenced by better-known phyla. Both morphological and molecular phylogeny analyses disagree over bryozoans' relationships with entoprocts, about whether bryozoans should be grouped with brachiopods and phoronids in Lophophorata, and whether bryozoans should be considered protostomes or deuterostomes. Description Distinguishing features Bryozoans, phoronids and brachiopods strain food out of the water by means of a lophophore, a "crown" of hollow tentacles. Bryozoans form colonies consisting of clones called zooids that are typically about long. Phoronids resemble bryozoan zooids but are long and, although they often grow in clumps, do not form colonies consisting of clones. Brachiopods, generally thought to be closely related to bryozoans and phoronids, are distinguished by having shells rather like those of bivalves. All three of these phyla have a coelom, an internal cavity lined by mesothelium. Some encrusting bryozoan colonies with mineralized exoskeletons look very like small corals. However, bryozoan colonies are founded by an ancestrula, which is round rather than shaped like a normal zooid of that species. On the other hand, the founding polyp of a coral has a shape like that of its daughter polyps, and coral zooids have no coelom or lophophore. Entoprocts, another phylum of filter-feeders, look rather like bryozoans but their lophophore-like feeding structure has solid tentacles, their anus lies inside rather than outside the base of the "crown" and they have no coelom. Types of zooid All bryozoans are colonial except for one genus, Monobryozoon. Individual members of a bryozoan colony are about long and are known as zooids, since they are not fully independent animals. All colonies contain feeding zooids, known as autozooids. Those of some groups also contain non-feeding heterozooids, also known as polymorphic zooids, which serve a variety of functions other than feeding; colony members are genetically identical and co-operate, rather like the organs of larger animals. What type of zooid grows where in a colony is determined by chemical signals from the colony as a whole or sometimes in response to the scent of predators or rival colonies. The bodies of all types have two main parts. The cystid consists of the body wall and whatever type of exoskeleton is secreted by the epidermis. The exoskeleton may be organic (chitin, polysaccharide or protein) or made of the mineral calcium carbonate. The latter is always absent in freshwater species. The body wall consists of the epidermis, basal lamina (a mat of non-cellular material), connective tissue, muscles, and the mesothelium which lines the coelom (main body cavity) – except that in one class, the mesothelium is split into two separate layers, the inner one forming a membranous sac that floats freely and contains the coelom, and the outer one attached to the body wall and enclosing the membranous sac in a pseudocoelom. The other main part of the bryozoan body, known as the polypide and situated almost entirely within the cystid, contains the nervous system, digestive system, some specialized muscles and the feeding apparatus or other specialized organs that take the place of the feeding apparatus. Feeding zooids The most common type of zooid is the feeding autozooid, in which the polypide bears a "crown" of hollow tentacles called a lophophore, which captures food particles from the water. In all colonies a large percentage of zooids are autozooids, and some consist entirely of autozooids, some of which also engage in reproduction. The basic shape of the "crown" is a full circle. Among the freshwater bryozoans (Phylactolaemata) the crown appears U-shaped, but this impression is created by a deep dent in the rim of the crown, which has no gap in the fringe of tentacles. The sides of the tentacles bear fine hairs called cilia, whose beating drives a water current from the tips of the tentacles to their bases, where it exits. Food particles that collide with the tentacles are trapped by mucus, and further cilia on the inner surfaces of the tentacles move the particles towards the mouth in the center. The method used by ectoprocts is called "upstream collecting", as food particles are captured before they pass through the field of cilia that creates the feeding current. This method is also used by phoronids, brachiopods and pterobranchs. The lophophore and mouth are mounted on a flexible tube called the "invert", which can be turned inside-out and withdrawn into the polypide, rather like the finger of a rubber glove; in this position the lophophore lies inside the invert and is folded like the spokes of an umbrella. The invert is withdrawn, sometimes within 60milliseconds, by a pair of retractor muscles that are anchored at the far end of the cystid. Sensors at the tips of the tentacles may check for signs of danger before the invert and lophophore are fully extended. Extension is driven by an increase in internal fluid pressure, which species with flexible exoskeletons produce by contracting circular muscles that lie just inside the body wall, while species with a membranous sac use circular muscles to squeeze this. Some species with rigid exoskeletons have a flexible membrane that replaces part of the exoskeleton, and transverse muscles anchored on the far side of the exoskeleton increase the fluid pressure by pulling the membrane inwards. In others there is no gap in the protective skeleton, and the transverse muscles pull on a flexible sac which is connected to the water outside by a small pore; the expansion of the sac increases the pressure inside the body and pushes the invert and lophophore out. In some species the retracted invert and lophophore are protected by an operculum ("lid"), which is closed by muscles and opened by fluid pressure. In one class, a hollow lobe called the "epistome" overhangs the mouth. The gut is U-shaped, running from the mouth, in the center of the lophophore, down into the animal's interior and then back to the anus, which is located on the invert, outside and usually below the lophophore. A network of strands of mesothelium called "funiculi" ("little ropes") connects the mesothelium covering the gut with that lining the body wall. The wall of each strand is made of mesothelium, and surrounds a space filled with fluid, thought to be blood. A colony's zooids are connected, enabling autozooids to share food with each other and with any non-feeding heterozooids. The method of connection varies between the different classes of bryozoans, ranging from quite large gaps in the body walls to small pores through which nutrients are passed by funiculi. There is a nerve ring round the pharynx (throat) and a ganglion that serves as a brain to one side of this. Nerves run from the ring and ganglion to the tentacles and to the rest of the body. Bryozoans have no specialized sense organs, but cilia on the tentacles act as sensors. Members of the genus Bugula grow towards the sun, and therefore must be able to detect light. In colonies of some species, signals are transmitted between zooids through nerves that pass through pores in the body walls, and coordinate activities such as feeding and the retraction of lophophores. The solitary individuals of Monobryozoon are autozooids with pear-shaped bodies. The wider ends have up to 15 short, muscular projections by which the animals anchor themselves to sand or gravel and pull themselves through the sediments. Avicularia and vibracula Some authorities use the term avicularia (plural of avicularium) to refer to any type of zooid in which the lophophore is replaced by an extension that serves some protective function, while others restrict the term to those that defend the colony by snapping at invaders and small predators, killing some and biting the appendages of others. In some species the snapping zooids are mounted on a peduncle (stalk), their bird-like appearance responsible for the term – Charles Darwin described these as like "the head and beak of a vulture in miniature, seated on a neck and capable of movement". Stalked avicularia are placed upside-down on their stalks. The "lower jaws" are modified versions of the opercula that protect the retracted lophophores in autozooids of some species, and are snapped shut "like a mousetrap" by similar muscles, while the beak-shaped upper jaw is the inverted body wall. In other species the avicularia are stationary box-like zooids laid the normal way up, so that the modified operculum snaps down against the body wall. In both types the modified operculum is opened by other muscles that attach to it, or by internal muscles that raise the fluid pressure by pulling on a flexible membrane. The actions of these snapping zooids are controlled by small, highly modified polypides that are located inside the "mouth" and bear tufts of short sensory cilia. These zooids appear in various positions: some take the place of autozooids, some fit into small gaps between autozooids, and small avicularia may occur on the surfaces of other zooids. In vibracula, regarded by some as a type of avicularia, the operculum is modified to form a long bristle that has a wide range of motion. They may function as defenses against predators and invaders, or as cleaners. In some species that form mobile colonies, vibracula around the edges are used as legs for burrowing and walking. Structural polymorphs Kenozooids (from the Greek 'empty') consist only of the body wall and funicular strands crossing the interior, and no polypide. The functions of these zooids include forming the stems of branching structures, acting as spacers that enable colonies to grow quickly in a new direction, strengthening the colony's branches, and elevating the colony slightly above its substrate for competitive advantages against other organisms. Some kenozooids are hypothesized to be capable of storing nutrients for the colony. Because kenozooids' function is generally structural, they are called "structural polymorphs." Some heterozooids found in extinct trepostome bryozoans, called mesozooids, are thought to have functioned to space the feeding autozooids an appropriate distance apart. In thin sections of trepostome fossils, mesozooids can be seen in between the tubes that held autozooids; they are smaller tubes that are divided along their length by diaphragms, making them look like rows of box-like chambers sandwiched between autozooidal tubes. Reproductive polymorphs Gonozooids act as brood chambers for fertilized eggs. Almost all modern cyclostome bryozoans have them, but they can be hard to locate on a colony because there are so few gonozooids in one colony. The aperture in gonozooids, which is called an ooeciopore, acts as a point for larvae to exit. Some gonozooids have very complex shapes with autozooidal tubes passing through chambers within them. All larvae released from a gonozooid are clones created by division of a single egg; this is called monozygotic polyembryony, and is a reproductive strategy also used by armadillos. Cheilostome bryozoans also brood their embryos; one of the common methods is through ovicells, capsules attached to autozooids. The autozooids possessing ovicells are normally still able to feed, however, so these are not considered heterozooids. "Female" polymorphs are more common than "male" polymorphs, but specialized zooids that produce sperm are also known. These are called androzooids, and some are found in colonies of Odontoporella bishopi, a species that is symbiotic with hermit crabs and lives on their shells. These zooids are smaller than the others and have four short tentacles and four long tentacles, unlike the autozooids which have 15–16 tentacles. Androzooids are also found in species with mobile colonies that can crawl around. It is possible that androzooids are used to exchange sperm between colonies when two mobile colonies or bryozoan-encrusted hermit crabs happen to encounter one another. Other polymorphs Spinozooids are hollow, movable spines, like very slender, small tubes, present on the surface of colonies, which probably are for defense. Some species have miniature nanozooids with small single-tentacled polypides, and these may grow on other zooids or within the body walls of autozooids that have degenerated. Colony forms and composition Although zooids are microscopic, colonies range in size from to over . However, the majority are under across. The shapes of colonies vary widely, depend on the pattern of budding by which they grow, the variety of zooids present and the type and amount of skeletal material they secrete. Some marine species are bush-like or fan-like, supported by "trunks" and "branches" formed by kenozooids, with feeding autozooids growing from these. Colonies of these types are generally unmineralized but may have exoskeletons made of chitin. Others look like small corals, producing heavy lime skeletons. Many species form colonies which consist of sheets of autozooids. These sheets may form leaves, tufts or, in the genus Thalamoporella, structures that resemble an open head of lettuce. The most common marine form, however, is encrusting, in which a one-layer sheet of zooids spreads over a hard surface or over seaweed. Some encrusting colonies may grow to over and contain about 2,000,000 zooids. These species generally have exoskeletons reinforced with calcium carbonate, and the openings through which the lophophores protrude are on the top or outer surface. The moss-like appearance of encrusting colonies is responsible for the phylum's name (Ancient Greek words meaning 'moss' and meaning 'animal'). Large colonies of encrusting species often have "chimneys", gaps in the canopy of lophophores, through which they swiftly expel water that has been sieved, and thus avoid re-filtering water that is already exhausted. They are formed by patches of non-feeding heterozooids. New chimneys appear near the edges of expanding colonies, at points where the speed of the outflow is already high, and do not change position if the water flow changes. Some freshwater species secrete a mass of gelatinous material, up to in diameter, to which the zooids stick. Other freshwater species have plant-like shapes with "trunks" and "branches", which may stand erect or spread over the surface. A few species can creep at about per day. Each colony grows by asexual budding from a single zooid known as the ancestrula, which is round rather than shaped like a normal zooid. This occurs at the tips of "trunks" or "branches" in forms that have this structure. Encrusting colonies grow round their edges. In species with calcareous exoskeletons, these do not mineralize until the zooids are fully grown. Colony lifespans range from one to about 12 years, and the short-lived species pass through several generations in one season. Species that produce defensive zooids do so only when threats have already appeared, and may do so within 48 hours. The theory of "induced defenses" suggests that production of defenses is expensive and that colonies which defend themselves too early or too heavily will have reduced growth rates and lifespans. This "last minute" approach to defense is feasible because the loss of zooids to a single attack is unlikely to be significant. Colonies of some encrusting species also produce special heterozooids to limit the expansion of other encrusting organisms, especially other bryozoans. In some cases this response is more belligerent if the opposition is smaller, which suggests that zooids on the edge of a colony can somehow sense the size of the opponent. Some species consistently prevail against certain others, but most turf wars are indecisive and the combatants soon turn to growing in uncontested areas. Bryozoans competing for territory do not use the sophisticated techniques employed by sponges or corals, possibly because the shortness of bryozoan lifespans makes heavy investment in turf wars unprofitable. Bryozoans have contributed to carbonate sedimentation in marine life since the Ordovician period. Bryozoans take responsibility for many of the colony forms, which have evolved in different taxonomic groups and vary in sediment producing ability. The nine basic bryozoan colony-forms include: encrusting, dome-shaped, palmate, foliose, fenestrate, robust branching, delicate branching, articulated and free-living. Most of these sediments come from two distinct groups of colonies: domal, delicate branching, robust branching and palmate; and fenestrate. Fenestrate colonies generate rough particles both as sediment and components of stromatoporoids coral reefs. The delicate colonies however, create both coarse sediment and form the cores of deep-water, subphotic biogenic mounds. Nearly all post- bryozoan sediments are made up of growth forms, with the addition to free-living colonies which include significant numbers of various colonies. "In contrast to the Palaeozoic, post-Palaeozoic bryozoans generated sediment varying more widely with the size of their grains; they grow as they moved from mud, to sand, to gravel." Taxonomy The phylum was originally called "Polyzoa", but this name was eventually replaced by Ehrenberg's term "Bryozoa". The name "Bryozoa" was originally applied only to the animals also known as Ectoprocta (), in which the anus lies outside the "crown" of tentacles. After the discovery of the Entoprocta (), in which the anus lies within a "crown" of tentacles, the name "Bryozoa" was promoted to phylum level to include the two classes Ectoprocta and Entoprocta. However, in 1869 Hinrich Nitsche regarded the two groups as quite distinct for a variety of reasons, and coined the name "Ectoprocta" for Ehrenberg's "Bryozoa". Despite their apparently similar methods of feeding, they differed markedly anatomically; in addition to the different positions of the anus, ectoprocts have hollow tentacles and a coelom, while entoprocts have solid tentacles and no coelom. Hence the two groups are now widely regarded as separate phyla, and the name "Bryozoa" is now synonymous with "Ectoprocta". This has remained the majority view ever since, although most publications have preferred the name "Bryozoa" rather than "Ectoprocta". Nevertheless, some notable scientists have continued to regard the "Ectoprocta" and Entoprocta as close relatives and group them under "Bryozoa". The ambiguity about the scope of the name "Bryozoa" led to proposals in the 1960s and 1970s that it should be avoided and the unambiguous term "Ectoprocta" should be used. However, the change would have made it harder to find older works in which the phylum was called "Bryozoa", and the desire to avoid ambiguity, if applied consistently to all classifications, would have necessitated renaming of several other phyla and many lower-level groups. In practice, zoological naming of split or merged groups of animals is complex and not completely consistent. Works since 2000 have used various names to resolve the ambiguity, including: "Bryozoa", "Ectoprocta", "Bryozoa (Ectoprocta)", and "Ectoprocta (Bryozoa)". Some have used more than one approach in the same work. The common name "moss animals" is the literal meaning of "Bryozoa", from Greek ('moss') and ('animals'), based on the mossy appearance of encrusting species. Until 2008 there were "inadequately known and misunderstood type species belonging to the Cyclostome Bryozoan family Oncousoeciidae." Modern research and experiments have been done using low-vacuum scanning electron microscopy of uncoated type material to critically examine and perhaps revise the taxonomy of three genera belonging to this family, including Oncousoecia, Microeciella, and Eurystrotos. This method permits data to be obtained that would be difficult to recognize with an optical microscope. The valid type species of Oncousoecia was found to be Oncousoecia lobulata. This interpretation stabilizes Oncousoecia by establishing a type species that corresponds to the general usage of the genus. Fellow Oncousoeciid Eurystrotos is now believed to be not conspecific with O. lobulata, as previously suggested, but shows enough similarities to be considered a junior synonym of Oncousoecia. Microeciella suborbicularus has also been recently distinguished from O. lobulata and O. dilatans, using this modern method of low vacuum scanning, with which it has been inaccurately synonymized with in the past. A new genus has also been recently discovered called Junerossia in the family Stomachetosellidae, along with 10 relatively new species of bryozoa such as Alderina flaventa, Corbulella extenuata, Puellina septemcryptica, Junerossia copiosa, Calyptotheca kapaaensis, Bryopesanser serratus, Cribellopora souleorum, Metacleidochasma verrucosa, Disporella compta, and Favosipora adunca. Classification and diversity Counts of formally described species range between 4,000 and 4,500. The Gymnolaemata and especially Cheilostomata have the greatest numbers of species, possibly because of their wide range of specialist zooids. Under the Linnaean system of classification, which is still used as a convenient way to label groups of organisms, living members of the phylum Bryozoa are divided into: Fossil record Fossils of about 15,000 bryozoan species have been found. Bryozoans are among the three dominant groups of Paleozoic fossils. Bryozoans with calcitic skeletons were a major source of the carbonate minerals that make up limestones, and their fossils are incredibly common in marine sediments worldwide from the Ordovician onward. However, unlike corals and other colonial animals found in the fossil record, Bryozoan colonies did not reach large sizes. Fossil bryozoan colonies are typically found highly fragmented and scattered; the preservation of complete zoaria is uncommon in the fossil record, and relatively little study has been devoted to reassembling fragmented zoaria. The largest known fossil colonies are branching trepostome bryozoans from Ordovician rocks in the United States, reaching 66 centimeters in height. The oldest species with a mineralized skeleton occurs in the Lower Ordovician. It is likely that the first bryozoans appeared much earlier and were entirely soft-bodied, and the Ordovician fossils record the appearance of mineralized skeletons in this phylum. By the Arenigian stage of the Early Ordovician period, about , all the modern orders of stenolaemates were present, and the ctenostome order of gymnolaemates had appeared by the Middle Ordovician, about . The Early Ordovician fossils may also represent forms that had already become significantly different from the original members of the phylum. Ctenostomes with phosphatized soft tissue are known from the Devonian. Other types of filter feeders appeared around the same time, which suggests that some change made the environment more favorable for this lifestyle. Fossils of cheilostomates, an order of gymnolaemates with mineralized skeletons, first appear in the Mid Jurassic, about , and these have been the most abundant and diverse bryozoans from the Cretaceous to the present. Evidence compiled from the last 100 million years show that cheilostomatids consistently grew over cyclostomatids in territorial struggles, which may help to explain how cheilostomatids replaced cyclostomatids as the dominant marine bryozoans. Marine fossils from the Paleozoic era, which ended , are mainly of erect forms, those from the Mesozoic are fairly equally divided by erect and encrusting forms, and more recent ones are predominantly encrusting. Fossils of the soft, freshwater phylactolaemates are very rare, appear in and after the Late Permian (which began about ) and consist entirely of their durable statoblasts. There are no known fossils of freshwater members of other classes. Evolutionary family tree Scientists are divided about whether the Bryozoa (Ectoprocta) are a monophyletic group (whether they include all and only a single ancestor species and all its descendants), about what are the phylum's closest relatives in the family tree of animals, and even about whether they should be regarded as members of the protostomes or deuterostomes, the two major groups that account for all moderately complex animals. Molecular phylogeny, which attempts to work out the evolutionary family tree of organisms by comparing their biochemistry and especially their genes, has done much to clarify the relationships between the better-known invertebrate phyla. However, the shortage of genetic data about "minor phyla" such as bryozoans and entoprocts has left their relationships to other groups unclear. Traditional view The traditional view is that the Bryozoa are a monophyletic group, in which the class Phylactolaemata is most closely related to Stenolaemata and Ctenostomatida, the classes that appear earliest in the fossil record. However, in 2005 a molecular phylogeny study that focused on phylactolaemates concluded that these are more closely related to the phylum Phoronida, and especially to the only phoronid species that is colonial, than they are to the other ectoproct classes. That implies that the Entoprocta are not monophyletic, as the Phoronida are a sub-group of ectoprocts but the standard definition of Entoprocta excludes the Phoronida. In 2009 another molecular phylogeny study, using a combination of genes from mitochondria and the cell nucleus, concluded that Bryozoa is a monophyletic phylum, in other words includes all the descendants of a common ancestor that is itself a bryozoan. The analysis also concluded that the classes Phylactolaemata, Stenolaemata and Gymnolaemata are also monophyletic, but could not determine whether Stenolaemata are more closely related to Phylactolaemata or Gymnolaemata. The Gymnolaemata are traditionally divided into the soft-bodied Ctenostomatida and mineralized Cheilostomata, but the 2009 analysis considered it more likely that neither of these orders is monophyletic and that mineralized skeletons probably evolved more than once within the early Gymnolaemata. Bryozoans' relationships with other phyla are uncertain and controversial. Traditional phylogeny, based on anatomy and on the development of the adult forms from embryos, has produced no enduring consensus about the position of ectoprocts. Attempts to reconstruct the family tree of animals have largely ignored ectoprocts and other "minor phyla", which have received little scientific study because they are generally tiny, have relatively simple body plans, and have little impact on human economies – despite the fact that the "minor phyla" include most of the variety in the evolutionary history of animals. In the opinion of Ruth Dewel, Judith Winston, and Frank McKinney, "Our standard interpretation of bryozoan morphology and embryology is a construct resulting from over 100 years of attempts to synthesize a single framework for all invertebrates," and takes little account of some peculiar features of ectoprocts. In ectoprocts, all of the larva's internal organs are destroyed during the metamorphosis to the adult form and the adult's organs are built from the larva's epidermis and mesoderm, while in other bilaterians some organs including the gut are built from endoderm. In most bilaterian embryos the blastopore, a dent in the outer wall, deepens to become the larva's gut, but in ectoprocts the blastopore disappears and a new dent becomes the point from which the gut grows. The ectoproct coelom is formed by neither of the processes used by other bilaterians, enterocoely, in which pouches that form on the wall of the gut become separate cavities, nor schizocoely, in which the tissue between the gut and the body wall splits, forming paired cavities. Entoprocts When entoprocts were discovered in the 19th century, they and bryozoans (ectoprocts) were regarded as classes within the phylum Bryozoa, because both groups were sessile animals that filter-fed by means of a crown of tentacles that bore cilia. From 1869 onwards increasing awareness of differences, including the position of the entoproct anus inside the feeding structure and the difference in the early pattern of division of cells in their embryos, caused scientists to regard the two groups as separate phyla, and "Bryozoa" became just an alternative name for ectoprocts, in which the anus is outside the feeding organ. A series of molecular phylogeny studies from 1996 to 2006 have also concluded that bryozoans (ectoprocts) and entoprocts are not sister groups. However, two well-known zoologists, Claus Nielsen and Thomas Cavalier-Smith, maintain on anatomical and developmental grounds that bryozoans and entoprocts are member of the same phylum, Bryozoa. A molecular phylogeny study in 2007 also supported this old idea, while its conclusions about other phyla agreed with those of several other analyses. Grouping into the Lophophorata By 1891 bryozoans (ectoprocts) were grouped with phoronids in a super-phylum called "Tentaculata". In the 1970s comparisons between phoronid larvae and the cyphonautes larva of some gymnolaete bryozoans produced suggestions that the bryozoans, most of which are colonial, evolved from a semi-colonial species of phoronid. Brachiopods were also assigned to the "Tentaculata", which were renamed Lophophorata as they all use a lophophore for filter feeding. The majority of scientists accept this, but Claus Nielsen thinks these similarities are superficial. The Lophophorata are usually defined as animals with a lophophore, a three-part coelom and a U-shaped gut. In Nielsen's opinion, phoronids' and brachiopods' lophophores are more like those of pterobranchs, which are members of the phylum Hemichordata. Bryozoan's tentacles bear cells with multiple cilia, while the corresponding cells of phoronids', brachiopods' and pterobranchs' lophophores have one cilium per cell; and bryozoan tentacles have no hemal canal ("blood vessel"), which those of the other three phyla have. If the grouping of bryozoans with phoronids and brachiopods into Lophophorata is correct, the next issue is whether the Lophophorata are protostomes, along with most invertebrate phyla, or deuterostomes, along with chordates, hemichordates and echinoderms. The traditional view was that lophophorates were a mix of protostome and deuterostome features. Research from the 1970s onwards suggested they were deuterostomes, because of some features that were thought characteristic of deuterostomes: a three-part coelom; radial rather than spiral cleavage in the development of the embryo; and formation of the coelom by enterocoely. However the coelom of ectoproct larvae shows no sign of division into three sections, and that of adult ectoprocts is different from that of other coelomate phyla as it is built anew from epidermis and mesoderm after metamorphosis has destroyed the larval coelom. Lophophorate molecular phylogenetics Molecular phylogeny analyses from 1995 onwards, using a variety of biochemical evidence and analytical techniques, placed the lophophorates as protostomes and closely related to annelids and molluscs in a super-phylum called Lophotrochozoa. "Total evidence" analyses, which used both morphological features and a relatively small set of genes, came to various conclusions, mostly favoring a close relationship between lophophorates and Lophotrochozoa. A study in 2008, using a larger set of genes, concluded that the lophophorates were closer to the Lophotrochozoa than to deuterostomes, but also that the lophophorates were not monophyletic. Instead, it concluded that brachiopods and phoronids formed a monophyletic group, but bryozoans (ectoprocts) were closest to entoprocts, supporting the original definition of "Bryozoa". They are the only major phylum of exclusively clonal animals, composed of modular units known as zooids. Because they thrive in colonies, colonial growth allows them to develop unrestricted variations in form. Despite this, only a small number of basic growth forms have been found and have commonly reappeared throughout the history of the bryozoa. Ectoproct molecular phylogenetics The phylogenetic position of the ectoproct bryozoans remains uncertain, but it remains certain that they belong to the Protostomia and more specifically to the Lophotrochozoa. This implies that the ectoproct larva is a trochophore with the corona being a homologue of the prototroch; this is supported from the similarity between the coronate larvae and the Type 1 pericalymma larvae of some molluscs and sipunculans, where the prototroch zone is expanded to cover the hyposphere. A study of the mitochondrial DNA sequence suggests that the Bryozoa may be related to the Chaetognatha. Physiology Feeding and excretion Most species are filter feeders that sieve small particles, mainly phytoplankton (microscopic floating plants), out of the water. The freshwater species Plumatella emarginata feeds on diatoms, green algae, cyanobacteria, non-photosynthetic bacteria, dinoflagellates, rotifers, protozoa, small nematodes, and microscopic crustaceans. While the currents that bryozoans generate to draw food towards the mouth are well understood, the exact method of capture is still debated. All species also flick larger particles towards the mouth with a tentacle, and a few capture zooplankton (planktonic animals) by using their tentacles as cages. In addition the tentacles, whose surface area is increased by microvilli (small hairs and pleats), absorb organic compounds dissolved in the water. Unwanted particles may be flicked away by tentacles or shut out by closing the mouth. A study in 2008 showed that both encrusting and erect colonies fed more quickly and grew faster in gentle than in strong currents. In some species the first part of the stomach forms a muscular gizzard lined with chitinous teeth that crush armored prey such as diatoms. Wave-like peristaltic contractions move the food through the stomach for digestion. The final section of the stomach is lined with cilia (minute hairs) that compress undigested solids, which then pass through the intestine and out through the anus. There are no nephridia ("little kidneys") or other excretory organs in bryozoa, and it is thought that ammonia diffuses out through the body wall and lophophore. More complex waste products are not excreted but accumulate in the polypide, which degenerates after a few weeks. Some of the old polypide is recycled, but much of it remains as a large mass of dying cells containing accumulated wastes, and this is compressed into a "brown body". When the degeneration is complete, the cystid (outer part of the animal) produces a new polypide, and the brown body remains in the coelom, or in the stomach of the new polypide and is expelled next time the animal defecates. Respiration and circulation There are no respiratory organs, heart or blood vessels. Instead, zooids absorb oxygen and eliminate carbon dioxide through diffusion. Bryozoa accomplish diffusion through the use of either a thin membrane (in the case of anascans and some polyzoa) or through pseudopores located on the outer dermis of the zooid. The different bryozoan groups use various methods to share nutrients and oxygen between zooids: some have quite large gaps in the body walls, allowing the coelomic fluid to circulate freely; in others, the funiculi (internal "little ropes") of adjacent zooids connect via small pores in the body wall. Reproduction and life cycles Zooids of all phylactolaemate species are simultaneous hermaphrodites. Although those of many marine species are protandric, in other words function first as males and then as females, their colonies contain a combination of zooids that are in their male and female stages. In all species the ovaries develop on the inside of the body wall, and the testes on the funiculus connecting the stomach to the body wall. Eggs and sperm are released into the coelom, and sperm exit into the water through pores in the tips of some of the tentacles, and then are captured by the feeding currents of zooids that are producing eggs. Some species' eggs are fertilized externally after being released through a pore between two tentacles, which in some cases is at the tip of a small projection called the "intertentacular organ" in the base of a pair of tentacles. Others' are fertilized internally, in the intertentacular organ or in the coelom. In ctenostomes the mother provides a brood chamber for the fertilized eggs, and her polypide disintegrates, providing nourishment to the embryo. Stenolaemates produce specialized zooids to serve as brood chambers, and their eggs divide within this to produce up to 100 identical embryos. The cleavage of bryozoan eggs is biradial, in other words the early stages are bilaterally symmetrical. It is unknown how the coelom forms, since the metamorphosis from larva to adult destroys all of the larva's internal tissues. In many animals the blastopore, an opening in the surface of the early embryo, tunnels through to form the gut. However, in bryozoans the blastopore closes, and a new opening develops to create the mouth. Bryozoan larvae vary in form, but all have a band of cilia round the body which enables them to swim, a tuft of cilia at the top, and an adhesive sac that everts and anchors them when they settle on a surface. Some gymnolaemate species produce cyphonautes larvae which have little yolk but a well-developed mouth and gut, and live as plankton for a considerable time before settling. These larvae have triangular shells of chitin, with one corner at the top and the base open, forming a hood round the downward-facing mouth. In 2006 it was reported that the cilia of cyphonautes larvae use the same range of techniques as those of adults to capture food. Species that brood their embryos form larvae that are nourished by large yolks, have no gut and do not feed, and such larvae quickly settle on a surface. In all marine species the larvae produce cocoons in which they metamorphose completely after settling: the larva's epidermis becomes the lining of the coelom, and the internal tissues are converted to a food reserve that nourishes the developing zooid until it is ready to feed. The larvae of phylactolaemates produce multiple polypides, so that each new colony starts with several zooids. In all species the founder zooids then grow the new colonies by budding clones of themselves. In phylactolaemates, zooids die after producing several clones, so that living zooids are found only round the edges of a colony. Phylactolaemates can also reproduce asexually by a method that enables a colony's lineage to survive the variable and uncertain conditions of freshwater environments. Throughout summer and autumn they produce disc-shaped statoblasts, masses of cells that function as "survival pods" rather like the gemmules of sponges. Statoblasts form on the funiculus connected to the parent's gut, which nourishes them. As they grow, statoblasts develop protective bivalve-like shells made of chitin. When they mature, some statoblasts stick to the parent colony, some fall to the bottom ("sessoblasts"), some contain air spaces that enable them to float ("floatoblasts"), and some remain in the parent's cystid to re-build the colony if it dies. Statoblasts can remain dormant for considerable periods, and while dormant can survive harsh conditions such as freezing and desiccation. They can be transported across long distances by animals, floating vegetation, currents and winds, and even in the guts of larger animals. When conditions improve, the valves of the shell separate and the cells inside develop into a zooid that tries to form a new colony. Plumatella emarginata produces both "sessoblasts", which enable the lineage to control a good territory even if hard times decimate the parent colonies, and "floatoblasts", which spread to new sites. New colonies of Plumatella repens produce mainly "sessoblasts" while mature ones switch to "floatoblasts". A study estimated that one group of colonies in a patch measuring produced 800,000 statoblasts. Cupuladriid Bryozoa are capable of both sexual and asexual reproduction. The sexually reproducing colonies (aclonal) are the result of a larval cupuladriid growing into an adult stage whereas the asexual colonies(clonal) are a result of a fragment of a colony of cupuladriids growing into its own colony. The different forms of reproduction in cupuladriids are achieved through a variety of methods depending on the morphology and classification of the zooid. Ecology Habitats and distribution Most marine species live in tropical waters at depths less than . However, a few have been found in deep-sea trenches, especially around cold seeps, and others near the poles. The great majority of bryozoans are sessile. Typically, sessile bryozoans live on hard substrates including rocks, sand or shells. Encrusting forms are much the commonest of these in shallow seas, but erect forms become more common as the depth increases. An example of incrustation on pebbles and cobbles is found in the diverse Pleistocene bryozoans found in northern Japan, where fossils have been found of single stones covered with more than 20 bryozoan species. Sediments with smaller particles, like sand or silt, are usually unsuitable habitat for bryozoans, but tiny colonies have been found encrusting grains of coarse sand. Some bryozoan species specialize in colonizing marine algae, seagrasses, and even mangrove roots; the genus Amphibiobeania lives on the leaves of mangrove trees and is called "amphibious" because it can survive regular exposure to air at low tide. There are a variety of "free-living" bryozoans that live un-attached to a substrate. A few forms such as Cristatella can move. Lunulitiform cheilostomes are one group of free-living bryozoans with mobile colonies. They form small round colonies un-attached to any substrate; colonies of the genus Selenaria have been observed to "walk" around using setae. Another cheilostome family, the Cupuladriidae, convergently evolved similarly shaped colonies capable of movement. When observed in an aquarium, Selenaria maculata colonies were recorded to crawl at a speed of one meter per hour, climb over each other, move toward light, and right themselves when turned upside-down. Later study of this genus showed that neuroelectrical activity in the colonies increased in correlation with movement toward light sources. It is theorized that the capacity for movement arose as a side effect when colonies evolved longer setae for unburying themselves from sediment. Other free-living bryozoans are moved freely by waves, currents, or other phenomena. An Antarctic species, Alcyonidium pelagosphaera, consists of floating colonies. The pelagic species is between in diameter, has the shape of a hollow sphere and consists of a single layer of autozooids. It is still not known if these colonies are pelagic their whole life or only represents a temporarily and previously undescribed juvenile stage. Colonies of the species Alcyonidium disciforme, which is disc-shaped and similarly free-living, inhabit muddy seabeds in the Arctic and can sequester sand grains they have engulfed, potentially using the sand as ballast to turn themselves right-side-up after they have been overturned. Some bryozoan species can form bryoliths, sphere-shaped free-living colonies that grow outward in all directions as they roll about on the seabed. In 2014 it was reported that the bryozoan Fenestrulina rugula had become a dominant species in parts of Antarctica. Global warming has increased the rate of scouring by icebergs, and this species is particularly adept at recolonizing scoured areas. The phylactolaemates live in all types of freshwater environment – lakes and ponds, rivers and streams, and estuaries – and are among the most abundant sessile freshwater animals. Some ctenostomes are exclusively freshwater while others prefer brackish water but can survive in freshwater. Scientists' knowledge of freshwater bryozoan populations in many parts of the world is incomplete, even in some parts of Europe. It was long thought that some freshwater species occurred worldwide, but since 2002 all of these have been split into more localized species. Bryozoans grow in clonal colonies. A larval Bryozoan settles on a hard substance and produces a colony asexually through budding. These colonies can grow thousands of individual zooids in a relatively short period of time. Even though colonies of zooids grow through asexual reproduction, Bryozoans are hermaphrodites and new colonies can be formed through sexual reproduction and the generation of free swimming larvae. When colonies grow too large, however, they can split in two. This is the only case where asexual reproduction results in a new colony separate from its predecessor. Most colonies are stationary. Indeed, these colonies tend to be settled on immobile substances such as sediment and coarse substances. There are some colonies of freshwater species such as Cristatella mucedo that are able to move slowly on a creeping foot. Interactions with non-human organisms Marine species are common on coral reefs, but seldom a significant proportion of the total biomass. In temperate waters, the skeletons of dead colonies form a significant component of shell gravels, and live ones are abundant in these areas. The marine lace-like bryozoan Membranipora membranacea produces spines in response to predation by several species of sea slugs (nudibranchs). Other predators on marine bryozoans include fish, sea urchins, pycnogonids, crustaceans, mites and starfish. In general marine echinoderms and molluscs eat masses of zooids by gouging pieces of colonies, breaking their mineralized "houses", while most arthropod predators on bryozoans eat individual zooids. In freshwater, bryozoans are among the most important filter feeders, along with sponges and mussels. Freshwater bryozoans are attacked by many predators, including snails, insects, and fish. In Thailand the introduced species Pomacea canaliculata (golden apple snail), which is generally a destructive herbivore, has wiped out phylactolaemate populations wherever it has appeared. P. canaliculata also preys on a common freshwater gymnolaemate, but with less devastating effect. Indigenous snails do not feed on bryozoans. Several species of the hydroid family Zancleidae have symbiotic relationships with bryozoans, some of which are beneficial to the hydroids while others are parasitic. Modifications appear in the shapes of some these hydroids, for example smaller tentacles or encrustation of the roots by bryozoans. The bryozoan Alcyonidium nodosum protects the whelk Burnupena papyracea against predation by the powerful and voracious rock lobster Jasus lalandii. While whelk shells encrusted by the bryozoans are stronger than those without this reinforcement, chemical defenses produced by the bryozoans are probably the more significant deterrent. In the Banc d'Arguin offshore Mauritania the species Acanthodesia commensale, which is generally growing attached to gravel and hard-substrate, has formed a facultative symbiotic relationship with hermit crabs of the species Pseudopagurus cf. granulimanus resulting in egg-size structures known as bryoliths. Nucleating on an empty gastropod shell, the bryozoan colonies form multilamellar skeletal crusts that produce spherical encrustations and extend the living chamber of the hermit crab through helicospiral tubular growth. Some phylactolaemate species are intermediate hosts for a group of myxozoa that have also been found to cause proliferative kidney disease, which is often fatal in salmonid fish, and has severely reduced wild fish populations in Europe and North America. Membranipora membranacea, whose colonies feed and grow exceptionally fast in a wide range of current speeds, was first noticed in the Gulf of Maine in 1987 and quickly became the most abundant organism living on kelps. This invasion reduced the kelp population by breaking their fronds, so that its place as the dominant "vegetation" in some areas was taken by another invader, the large alga Codium fragile tomentosoides. These changes reduced the area of habitat available for local fish and invertebrates. M. membranacea has also invaded the northwest coast of the US. A few freshwater species have been also found thousands of kilometers from their native ranges. Some may have been transported naturally as statoblasts. Others more probably were spread by humans, for example on imported water plants or as stowaways on ships. Interaction with humans Fish farms and hatcheries have lost stock to proliferative kidney disease, which is caused by one or more myxozoans that use bryozoans as alternate hosts. Some fishermen in the North Sea have had to find other work because of a form of eczema (a skin disease) known as "Dogger Bank itch", caused by contact with bryozoans that have stuck to nets and lobster pots. Marine bryozoans are often responsible for biofouling on ships' hulls, on docks and marinas, and on offshore structures. They are among the first colonizers of new or recently cleaned structures. Freshwater species are occasional nuisances in water pipes, drinking water purification equipment, sewage treatment facilities, and the cooling pipes of power stations. A group of chemicals called bryostatins can be extracted from the marine bryozoan Bugula neritina. In 2001 pharmaceutical company GPC Biotech licensed bryostatin 1 from Arizona State University for commercial development as a treatment for cancer. GPC Biotech canceled development in 2003, saying that bryostatin 1 showed little effectiveness and some toxic side effects. In January 2008 a clinical trial was submitted to the United States National Institutes of Health to measure the safety and effectiveness of Bryostatin 1 in the treatment of Alzheimer's disease. However, no participants had been recruited by the end of December 2008, when the study was scheduled for completion. More recent work shows it has positive effects on cognition in patients with Alzheimer's disease with few side effects. About of bryozoans must be processed to extract of bryostatin, As a result, synthetic equivalents have been developed that are simpler to produce and apparently at least as effective.

Beavis and Butt-Head

Beavis and Butt-Head is an American adult animated television series created by Mike Judge for MTV (seasons 1–8) and later Paramount+ (season 9–present, as Mike Judge's Beavis and Butt-Head). The series follows Beavis and Butt-Head, both voiced by Judge, a pair of teenage slackers characterized by their apathy, lack of intelligence, lowbrow humor, and love for hard rock and heavy metal. The characters originated in Judge's 1992 short film Frog Baseball with the second film being called Peace, Love and Understanding, which was broadcast by MTV's animation showcase Liquid Television. After MTV commissioned a full series, Beavis and Butt-Head ran for seven seasons from 1993 to 1997. It was revived with an eighth season aired on MTV in 2011. A second revival, consisting of an initial two-season order, premiered on Paramount+ in 2022. During its initial run, Beavis and Butt-Head received critical acclaim for its satirical, scathing commentary on society, as well as criticism for its alleged influence on adolescents. It produced various other media, including the theatrical film Beavis and Butt-Head Do America in 1996. A second film, Beavis and Butt-Head Do the Universe, was released in 2022 on Paramount+. Premise Beavis and Butt-Head are unintelligent teenage boys who live in the town of Highland, Texas. Rolling Stone described them as "thunderously stupid and excruciatingly ugly". They spend time watching television, drinking unhealthy beverages, eating, and embarking on "mundane, sordid" adventures, which often involve vandalism, abuse, violence, or animal cruelty. According to The Baltimore Sun, Beavis and Butt-Head are "at their most incorrect when it comes to sexuality and matters of gender. The nicest thing you can say about them in this regard is that they are budding misogynists." When Beavis consumes too much caffeine or sugar, he becomes Cornholio, a hyperactive alter ego. Over the course of the series, Beavis and Butt-Head developed more distinct personalities; Butt-Head is the leader and "devious visionary", while Beavis, the sidekick, is the "loose cannon". Most episodes integrate sequences where Beavis and Butt-Head watch music videos and offer commentary. They prefer videos with "explosions, loud guitars, screaming and death", and favor rock bands such as the Butthole Surfers, Corrosion of Conformity, and Metallica. Judge said he saw Beavis and Butt-Head as "pretty positive characters, generally speaking ... They usually think everything's pretty cool. Or, in one way or another, everything sucks." He said his perception of the characters changed over the years: "When I first started out with the first show, which was Frog Baseball, they were just two guys that I would definitely want to keep my distance from ... But, by the end of the series, I would think that two guys like that would at least be fun to sit and watch TV with." Voice cast Mike Judge as Beavis, Butt-Head, Principal McVicker, Coach Buzzcut, David Van Driessen, Tom Anderson, Todd, and others Tracy Grandstaff as Daria Morgendorffer and Mrs. Stevenson Kristofer Brown as various History 1993–1997: First seven seasons and first film Beavis and Butt-Head was created by the American animator Mike Judge for his short film Frog Baseball, which was played on MTV's animation showcase Liquid Television. MTV ordered a full series, which ran for seven seasons from March 8, 1993, to November 28, 1997. Judge is critical of the animation in earlier episodes, in particular the first two—"Give Blood/Blood Drive" and "Door to Door"—which he described as "Horrible. Those first two episodes were awful, I don't know why anybody liked it... I was burying my head in the sand." In addition, the studio which worked on the first season was supposed to have 22 episodes done by March 8, 1993, and only had two finished ("Give Blood/Blood Drive" and "Door to Door"). In 1993, Rolling Stone described Beavis and Butt-Head as the "biggest phenomenon on MTV since the heyday of Michael Jackson". In Time, Kurt Andersen wrote that Beavis and Butt-Head "may be the bravest show ever run on national television". In 1997, Judge said the show was "my reaction to the whole fringe aspects of the political correctness movement". Beavis and Butt-Head became pop culture icons and their sniggering and dialogue became catchphrases. From 1994 to 1996, Marvel Comics published a monthly Beavis and Butt-Head comic under the Marvel Absurd imprint by a variety of writers, but with each issue drawn by artist Rick Parker. It was also reprinted by Marvel UK, which created new editorial material. A theatrical film, Beavis and Butt-Head Do America, released in the US 1996 and later in the UK and Europe in 1997. It features the voices of Bruce Willis, Demi Moore, Cloris Leachman, Robert Stack, Eric Bogosian, Richard Linklater, Greg Kinnear (in an uncredited role) and David Letterman (credited as Earl Hofert). It opened at number one at the US box office and grossed more than $60 million 2011: Eighth season On July 14, 2010, a spokesperson for MTV Networks informed a New York Post reporter that Mike Judge was creating a new Beavis and Butt-Head series, that Judge would reprise his voice-acting roles for the show, and that the animation would be hand-drawn. According to TMZ, MTV had not asked Tracy Grandstaff to reprise her role as Daria Morgendorffer. Later, in a Rolling Stone interview, Judge was asked if Daria was coming back, and he said: "No. There's sort of a cameo in one episode. That'll be a surprise." As in the old series, Beavis and Butt-Head are high school students who, among other things, criticize contemporary music videos. In an interview with Rolling Stone, MTV president Van Toffler said the duo would also watch Jersey Shore, Ultimate Fighting Championship matches, and amateur videos from YouTube, as well as give movie reviews. "The biggest change is obviously the references are updated, it's set in modern day, and there's going to be a movie review segment," Linn said, "Otherwise they're still true to their prior passions." John Altschuler, formerly a writer for King of the Hill, told a Rolling Stone reporter that he saw signs that Mike Judge was thinking of reviving Beavis and Butt-Head. On more than one occasion, Judge told the writers that one of their ideas for an episode of King of the Hill would work well for Beavis and Butt-Head; eventually he concluded, "Maybe we should just actually make some good Beavis and Butt-Head episodes." Later, a Lady Gaga video convinced Van Toffler of the tenability of a Beavis and Butt-Head revival: "I felt like there was a whole crop of new artists—and what the world sorely missed was the point of view that only Beavis and Butt-Head could bring." As part of a promotional campaign for the new series, cinemas screening Jackass 3D opened the feature film with a 3-D Beavis and Butt-Head short subject. Months later, in a media presentation on February 2, 2011, MTV announced that the series would premiere in mid-2011. On July 21, 2011, Judge spoke and fielded questions on a panel at Comic-Con International. A preview of the episode "Holy Cornholio" was also shown. Judge told Rolling Stone that at least 24 episodes (12 half-hour programs) will definitely air. The new episodes debuted in the United States and Canada on October 27, 2011. Conflicting with the actual season number, MTV incorrectly refers to this season as "Season 9", even though it is technically the eighth season. The premiere was dubbed a ratings hit with an audience of 3.3 million total viewers. This number eventually dwindled to 900,000 by the season's end, mainly due to its challenging time slot pitted against regular prime time shows on other networks. According to Mike Judge, MTV's modern demographic are females 12–14 years old. On July 28, 2016, it was reported that VH1 Classic was to be rebranded as MTV Classic on August 1, 2016, on the 35th anniversary of the original MTV. With a focus on 1990s programming, Beavis and Butt-Head were a major part of this alongside Daria and Æon Flux at the launch; they were also a major focus in the promotion of the re-brand. MTV Classic only broadcast episodes from the 2011 reboot. However, it and all non-music video programming only lasted a few months before being pulled. 2022–present: Second film and revival In May 2008, Judge stated that he previously hated the idea of producing a live-action film, but had come to believe that "maybe there's something there." He also revealed that Johnny Depp had expressed interest in the role of Beavis, having imitated the character while Marlon Brando imitated Butt-Head during the production of Don Juan DeMarco (1995). He also stated in an interview that "Seann William Scott's kinda got Butt-Head eyes." In 2016, Judge told Radio Times "Maybe it could be a live-action someday", then went on to speculate that Beavis might be homeless by now. In August 2009, Judge stated, "I like to keep the door open on Beavis and Butt-Head, because it's my favorite thing that I've ever done. It's the thing I'm most proud of." While promoting his film Extract that month, Judge said he would like to see the characters on the big screen again, and that "I kind of think of them as being either 15 or in their 60s.... I wouldn't mind doing something with them as these two dirty old men sitting on the couch." On January 10, 2014, Judge announced that, while he was busy working on Silicon Valley, there was a chance of his pitching Beavis and Butt-Head to another network and that he would not mind making more episodes. During an interview with Howard Stern on May 6, 2014, Judge mentioned that the show's ratings on MTV were second only to Jersey Shore, but the show did not fit MTV's target demographic of young women, which is why the revived series has not been brought back on MTV. He also said that MTV was close to selling it to another network, but it became "lost in deal stuff". On July 1, 2020, Comedy Central announced it had ordered a second revival of the series consisting of two new seasons along with spin-offs and specials. In the new series, Beavis and Butt-Head will enter a "whole new Gen Z world" with meta-themes that are said to be relatable to both new fans, who may be unfamiliar with the original series, and old. Mike Judge would return as the writer, producer, and principal voice actor for the series. In February 2022, it was announced that the revival would instead premiere on Paramount+, following a second Beavis and Butt-Head feature film entitled Beavis and Butt-Head Do the Universe. Originally, Paramount executives wanted a live-action Beavis and Butt-Head movie. Judge held auditions over Zoom for the project. He eventually talked the company into doing an animated movie instead to reestablish the characters first, with a future live-action movie still a possibility. In June 2022, it was confirmed that new episodes would debut later that year, along with the full library of over 227 original episodes, newly remastered, with music videos intact. One month later, it was announced that the revival would premiere on August 4, 2022. Season 9 continued the concept of the Beavis and Butt-Head multiverse initially explored in Beavis and Butt-Head Do the Universe. Teenage Beavis and Butt-Head, Old Beavis and Butt-Head, and Smart Beavis and Butt-Head all get their own dedicated episodes in the revival. On March 8, 2023, Paramount+ announced that the series would return with a new season, which would premiere on April 20, 2023 in the US and Canada, and in Australia and the UK on April 21, with further international markets to follow. Episodes Reception During its original run, Beavis and Butt-Head was MTV's highest rated show. It was one of the most popular series when it premiered in 1993. Over its run, Beavis and Butt-Head received both positive and negative reactions from the public with its combination of lewd humor and implied criticism of society. It became the focus of criticism from some social critics such as Michael Medved, while others such as David Letterman and the National Review defended it as a cleverly subversive vehicle for social criticism and a particularly creative and intelligent comedy. Either way, the show captured the attention of many young television viewers and is often considered a classic piece of 1990s youth culture and Generation X. Trey Parker and Matt Stone, creators of South Park, cite the series as an influence and compared it to the blues. In 1997, Dan Tobin of The Boston Phoenix commented on the series' humor, saying it transformed "stupidity into a crusade, forcing us to acknowledge how little it really takes to make us laugh." In 1997, Ted Drozdowski of The Boston Phoenix described the 1997 Beavis and Butt-Head state as "reduced to self-parody of their self-parody". In the Baltimore Sun, David Zurawik said that Beavis and Butt-Head was "intelligent social satire that especially speaks in a meaningful way to a generation of teenage boys who are going through a uniquely complicated socialization at the hands of their baby-boomer parents". He said that its popularity may have taught audiences about male adolescence in the 1990s; he wrote that they were the postmodern descendants of Tom Sawyer and Huckleberry Finn, who were the "exemplars of males coming of age in American popular culture". In December 2005, TV Guide ranked the duo's distinct laughing at #66 on their list of the 100 Greatest TV Quotes and Catchphrases. In 2012, TV Guide ranked Beavis and Butt-Head as one of the top 60 Greatest TV Cartoons of All Time. Controversies The show was blamed for the death of two-year-old Jessica Matthews in Moraine, Ohio, in October 1993. The girl's five-year-old brother, Austin Messner, set fire to his mother's mobile home with a cigarette lighter, killing the two-year-old. The mother later claimed that her son watched an episode in which the characters said "fire was fun". However, the neighbors stated that the family did not even have cable television and would thus be unable to view the show. As a result, all references to fire were removed from subsequent airings and prompted the show to a later time slot. The creators found a censorship loophole and took delight in sometimes making Beavis scream things that sounded very similar to his previous "Fire! Fire!" (such as "Fryer! Fryer!" when he and Butt-Head are working the late shift at Burger World) and also having him almost say the forbidden word (such as one time when he sang "Liar, liar, pants on..." and pausing before "fire"). There was also a music video where a man runs on fire in slow motion ("California" by Wax). Beavis is hypnotized by it and can barely say "fire". However, MTV eventually removed the episode entirely, leading it to be locked away in the MTV vault. References to fire were cut from earlier episodes—even the original master tapes were altered permanently. Other episodes MTV opted not to rerun included "Stewart's House" and "Way Down Mexico Way". Copies of early episodes with the controversial content intact are rare, and the copies that exist are made from home video recordings of the original broadcasts, typically on VHS. In an interview included with the Mike Judge Collection DVD set, Judge said he is uncertain whether some of the earlier episodes still exist in their original, uncensored form. When the series returned in 2011, MTV allowed Beavis to use the word "fire" once again uncensored. During the first video segment, "Werewolves of Highland", the first new episode of the revival, Beavis utters the word "fire" a total of seven times within 28 seconds, with Butt-Head saying it once as well. In February 1994, watchdog group Morality in Media claimed that the death of eight-month-old Natalia Rivera, struck by a bowling ball thrown from an overpass onto a highway in Jersey City, New Jersey, near the Holland Tunnel by 18-year-old Calvin J. Settle, was partially inspired by Beavis and Butt-Head. The group said that Settle was influenced by the episode "Ball Breakers", in which Beavis and Butt-Head load a bowling ball with explosives and drop it from a rooftop. While Morality in Media claimed that the show inspired Settle's actions, the case's prosecutors did not. It was later revealed by both prosecutors and the defendant that Settle did not have cable TV, nor did he watch the show. MTV also responded by broadcasting the program after 11:00 p.m. and included a disclaimer, reminding viewers: Beavis and Butt-Head are not real. They are stupid cartoon people completely made up by this Texas guy whom we hardly even know. Beavis and Butt-Head are dumb, crude, thoughtless, ugly, sexist, self-destructive fools. But for some reason, the little wienerheads make us laugh. This was later changed to: Beavis and Butt-Head are not role models. They're not even human. They're cartoons. Some of the things they do would cause a person to get hurt, expelled, arrested, possibly deported. To put it another way: don't try this at home. This disclaimer also appears before the opening of their Sega Genesis and Super NES games as well as their Windows game Beavis and Butt-Head in Virtual Stupidity. They were famously lambasted by Senator Fritz Hollings (D-SC) as "Buffcoat and Beaver". This subsequently became a running gag on the show where adults mispronounced their names. For example, one character on the show, Tom Anderson, originally called them "Butthole" and "Joe" and believed the two to be of Asian ethnicity (describing them to the police as "Oriental"). In later episodes, Anderson uses the Hollings mispronunciation once and, on at least one occasion, refers to them as "Penis and Butt-Munch". President Clinton called them "Beavis and Bum-head" in "Citizen Butt-head", as well as in the movie, where an old lady (voiced by Cloris Leachman) consistently calls them "Travis" and "Bob-head". In "Incognito", when another student threatens to kill them, the duo uses this to their advantage, pretending to be exchange students named "Crevis and Bung-Head". The bully, seeing through the disguises, calls them "Beaver and Butt-Plug". In "Right On!", when the duo appear on the Gus Baker Show, host Gus Baker (a caricature of Rush Limbaugh) introduces them as "Beavis and Buffcoat". And in the original series finale, "Beavis and Butt-head Are Dead", a news reporter refers to the two boys as "Brevis and Head-Butt". In the Season 9 episode "Locked Out" Tom Anderson mistakes Beavis and Butthead for honest and responsible boys, and blames "Buford" and "Bernardo" for the alleged damage to the paint on his new truck, though Beavis and Butthead lied about the damage. Beavis and Butt-Head have been compared to idiot savants because of their creative and subversively intelligent observations of music videos. This part of the show was mostly improvised by Mike Judge. With regard to criticisms of the two as "idiots", Judge responded that a show about straight-A students would not be funny. Guinness World Records On September 25, 2022, Beavis and Butt-Head and Paramount+ attempted to break the world record for the largest serving of nachos at S. Alameda St in Los Angeles to celebrate the return of the show. They were successful and were given a ceremonial plaque from the Guinness World Records representative which stated "The largest serving of nachos was achieved by Mike Judge's Beavis and Butt-Head and Paramount+." Related media Daria A spin-off based on classmate Daria Morgendorffer premiered in 1997. Mike Judge was not involved at all except to give permission for use of the character (created by Glenn Eichler and designed by Bill Peckmann). The only reference to the original show is Daria's mentioning that Lawndale cannot be a second Highland "unless there's uranium in the drinking water here too".

Bulletin board system

A bulletin board system (BBS), also called a computer bulletin board service (CBBS), is a computer server running software that allows users to connect to the system using a terminal program. Once logged in, the user can perform functions such as uploading and downloading software and data, reading news and bulletins, and exchanging messages with other users through public message boards and sometimes via direct chatting. In the early 1980s, message networks such as FidoNet were developed to provide services such as NetMail, which is similar to internet-based email. Many BBSes also offer online games in which users can compete with each other. BBSes with multiple phone lines often provide chat rooms, allowing users to interact with each other. Bulletin board systems were in many ways a precursor to the modern form of the World Wide Web, social networks, and other aspects of the Internet. Low-cost, high-performance asynchronous modems drove the use of online services and BBSes through the early 1990s. InfoWorld estimated that there were 60,000 BBSes serving 17 million users in the United States alone in 1994, a collective market much larger than major online services such as CompuServe. The introduction of inexpensive dial-up internet service and the Mosaic web browser offered ease of use and global access that BBS and online systems did not provide, and led to a rapid crash in the market starting in late 1994 to early 1995. Over the next year, many of the leading BBS software providers went bankrupt and tens of thousands of BBSes disappeared. Today, BBSing survives largely as a nostalgic hobby in most parts of the world, but it is still an extremely popular form of communication for Taiwanese youth (see PTT Bulletin Board System). Most surviving BBSes are accessible over Telnet and typically offer free email accounts, FTP services, IRC and all the protocols commonly used on the Internet. Some offer access through packet switched networks or packet radio connections. History Precursors A precursor to the public bulletin board system was Community Memory, started in August 1973 in Berkeley, California. Useful microcomputers did not exist at that time, and modems were both expensive and slow. Community Memory therefore ran on a mainframe computer and was accessed through terminals located in several San Francisco Bay Area neighborhoods. The poor quality of the original modem connecting the terminals to the mainframe prompted Community Memory hardware person, Lee Felsenstein, to invent the Pennywhistle modem, whose design was highly influential in the mid-1970s. Community Memory allowed the user to type messages into a computer terminal after inserting a coin, and offered a "pure" bulletin board experience with public messages only (no email or other features). It did offer the ability to tag messages with keywords, which the user could use in searches. The system acted primarily in the form of a buy and sell system with the tags taking the place of the more traditional classifications. But users found ways to express themselves outside these bounds, and the system spontaneously created stories, poetry and other forms of communications. The system was expensive to operate, and when their host machine became unavailable and a new one could not be found, the system closed in January 1975. Similar functionality was available to most mainframe users, which might be considered a sort of ultra-local BBS when used in this fashion. Commercial systems, expressly intended to offer these features to the public, became available in the late 1970s and formed the online service market that lasted into the 1990s. One particularly influential example was PLATO, which had thousands of users by the late 1970s, many of whom used the messaging and chat room features of the system in the same way that would later become common on BBSes. The first BBSes Early modems were generally either expensive or very simple devices using acoustic couplers to handle telephone operation. The user would pick up the phone, dial a number, then press the handset into rubber cups on the top of the modem. Disconnecting at the end of a call required the user to pick up the handset and return it to the phone. Examples of direct-connecting modems did exist, and these often allowed the host computer to send it commands to answer or hang up calls, but these were very expensive devices used by large banks and similar companies. With the introduction of microcomputers with expansion slots, like the S-100 bus machines and Apple II, it became possible for the modem to communicate instructions and data on separate lines. These machines typically only supported asynchronous communications, and synchronous modems were much more expensive than asynchronous modems. A number of modems of this sort were available by the late 1970s. This made the BBS possible for the first time, as it allowed software on the computer to pick up an incoming call, communicate with the user, and then hang up the call when the user logged off. The first public dial-up BBS was developed by Ward Christensen and Randy Suess, members of the Chicago Area Computer Hobbyists' Exchange (CACHE). According to an early interview, when Chicago was snowed under during the Great Blizzard of 1978, the two began preliminary work on the Computerized Bulletin Board System, or CBBS. The system came into existence largely through a fortuitous combination of Christensen having a spare S-100 bus computer and an early Hayes internal modem, and Suess's insistence that the machine be placed at his house in Chicago where it would be a local phone call for more users. Christensen patterned the system after the cork board his local computer club used to post information like "need a ride". CBBS officially went online on 16 February 1978. CBBS, which kept a count of callers, reportedly connected 253,301 callers before it was finally retired. Smartmodem A key innovation required for the popularization of the BBS was the Smartmodem manufactured by Hayes Microcomputer Products. Internal modems like the ones used by CBBS and similar early systems were usable, but generally expensive due to the manufacturer having to make a different modem for every computer platform they wanted to target. They were also limited to those computers with internal expansion, and could not be used with other useful platforms like video terminals. External modems were available for these platforms but required the phone to be dialed using a conventional handset. Internal modems could be software-controlled to perform both outbound and inbound calls, but external modems had only the data pins to communicate with the host system. Hayes' solution to the problem was to use a small microcontroller to implement a system that examined the data flowing into the modem from the host computer, watching for certain command strings. This allowed commands to be sent to and from the modem using the same data pins as all the rest of the data, meaning it would work on any system that could support even the most basic modems. The Smartmodem could pick up the phone, dial numbers, and hang up again, all without any operator intervention. The Smartmodem was not necessary for BBS use but made overall operation dramatically simpler. It also improved usability for the caller, as most terminal software allowed different phone numbers to be stored and dialed on command, allowing the user to easily connect to a series of systems. The introduction of the Smartmodem led to the first real wave of BBS systems. Limited in both speed and storage capacity, these systems were normally dedicated solely to messaging, both private email and public forums. File transfers were extremely slow at these speeds, and file libraries were typically limited to text files containing lists of other BBS systems. These systems attracted a particular type of user who used the BBS as a unique type of communications medium, and when these local systems were crowded from the market in the 1990s, their loss was lamented for many years. Higher speeds, commercialization Speed improved with the introduction of 1200 bit/s asynchronous modems in the early 1980s, giving way to 2400 bit/s fairly rapidly. The improved performance led to a substantial increase in BBS popularity. Most of the information was displayed using ordinary ASCII text or ANSI art, but a number of systems attempted character-based graphical user interfaces which began to be practical at 2400 bit/s. There was a lengthy delay before 9600 bit/s models began to appear on the market. 9600 bit/s was not even established as a strong standard before V.32bis at 14.4 kbit/s took over in the early 1990s. This period also saw the rapid rise in capacity and a dramatic drop in the price of hard drives. By the late 1980s, many BBS systems had significant file libraries, and this gave rise to leechingusers calling BBSes solely for their files. These users would use the modem for some time, leaving less time for other users, who got busy signals. The resulting upheaval eliminated many of the pioneering message-centric systems. This also gave rise to a new class of BBS systems, dedicated solely to file upload and downloads. These systems charged for access, typically a flat monthly fee, compared to the per-hour fees charged by Event Horizons BBS and most online services. Many third-party services were developed to support these systems, offering simple credit card merchant account gateways for the payment of monthly fees, and entire file libraries on compact disk that made initial setup very easy. Early 1990s editions of Boardwatch were filled with ads for single-click install solutions dedicated to these new sysops. While this gave the market a bad reputation, it also led to its greatest success. During the early 1990s, there were a number of mid-sized software companies dedicated to BBS software, and the number of BBSes in service reached its peak. Towards the early 1990s, BBS became so popular that it spawned three monthly magazines, Boardwatch, BBS Magazine, and in Asia and Australia, Chips 'n Bits Magazine which devoted extensive coverage of the software and technology innovations and people behind them, and listings to US and worldwide BBSes. In addition, in the US, a major monthly magazine, Computer Shopper, carried a list of BBSes along with a brief abstract of each of their offerings. GUIs Through the late 1980s and early 1990s, there was considerable experimentation with ways to develop user-friendly interfaces for BBSes. Almost every popular system used ANSI-based color menus to make reading easier on capable hardware and terminal emulators, and most also allowed cursor commands to offer command-line recall and similar features. Another common feature was the use of autocomplete to make menu navigation simpler, a feature that would not re-appear on the Web until decades later. A number of systems also made forays into GUI-based interfaces, either using character graphics sent from the host, or using custom GUI-based terminal systems. The latter initially appeared on the Macintosh platform, where TeleFinder and FirstClass became very popular. FirstClass offered a host of features that would be difficult or impossible under a terminal-based solution, including bi-directional information flow and non-blocking operation that allowed the user to exchange files in both directions while continuing to use the message system and chat, all in separate windows. Will Price's "Hermes", released in 1988, combined a familiar PC style with Macintosh GUI interface. (Hermes was already "venerable" by 1994 although the Hermes II release remained popular.) Skypix featured on Amiga a complete markup language. It used a standardized set of icons to indicate mouse driven commands available online and to recognize different filetypes present on BBS storage media. It was capable of transmitting data like images, audio files, and audio clips between users linked to the same BBS or off-line if the BBS was in the circuit of the FidoNet organization. On the PC, efforts were more oriented to extensions of the original terminal concept, with the GUI being described in the information on the host. One example was the Remote Imaging Protocol, essentially a picture description system, which remained relatively obscure. Probably the ultimate development of this style of operation was the dynamic page implementation of the University of Southern California BBS (USCBBS) by Susan Biddlecomb, which predated the implementation of the HTML Dynamic web page. A complete Dynamic web page implementation was accomplished using TBBS with a TDBS add-on presenting a complete menu system individually customized for each user. Rise of the Internet and decline of BBS The demand for complex ANSI and ASCII screens and larger file transfers taxed available channel capacity, which in turn increased demand for faster modems. 14.4 kbit/s modems were standard for a number of years while various companies attempted to introduce non-standard systems with higher performancenormally about 19.2 kbit/s. Another delay followed due to a long V.34 standards process before 28.8 kbit/s was released, only to be quickly replaced by 33.6 kbit/s, and then 56 kbit/s. These increasing speeds had the side effect of dramatically reducing the noticeable effects of channel efficiency. When modems were slow, considerable effort was put into developing the most efficient protocols and display systems possible. TCP/IP ran slowly over 1200 bit/s modems. 56 kbit/s modems could access the protocol suite more quickly than with slower modems. Dial-up Internet service became widely available in the mid-1990s to the general public outside of universities and research laboratories, and connectivity was included in most general-use operating systems by default as Internet access became popular. These developments together resulted in the sudden obsolescence of bulletin board technology in 1995 and the collapse of its supporting market. Technically, Internet service offered an enormous advantage over BBS systems, as a single connection to the user's Internet service provider allowed them to contact services around the world. In comparison, BBS systems relied on a direct point-to-point connection, so even dialing multiple local systems required multiple phone calls. Internet protocols also allowed a single connection to be used to contact multiple services simultaneously; for example, downloading files from an FTP library while checking the weather on a local news website. In comparison, a connection to a BBS allowed access only to the information on that system. Estimating numbers According to the FidoNet Nodelist, BBSes reached their peak usage around 1996, which was the same period that the World Wide Web and AOL became mainstream. BBSes rapidly declined in popularity thereafter, and were replaced by systems using the Internet for connectivity. Some of the larger commercial BBSes, such as MaxMegabyte and ExecPC BBS, evolved into Internet service providers. The website textfiles.com serves as an archive that documents the history of the BBS. The historical BBS list on textfiles.com contains over 105,000 BBSes that have existed over a span of 20 years in North America alone. The owner of textfiles.com, Jason Scott, also produced BBS: The Documentary, a DVD film that chronicles the history of the BBS and features interviews with well-known people (mostly from the United States) from the heyday BBS era. In the 2000s, most traditional BBS systems migrated to the Internet using Telnet or SSH protocols. As of September 2022, between 900 and 1000 are thought to be active via the Internet fewer than 30 of these being of the traditional "dial-up" (modem) variety. Software and hardware Unlike modern websites and online services that are typically hosted by third-party companies in commercial data centers, BBS computers (especially for smaller boards) were typically operated from the system operator's home. As such, access could be unreliable, and in many cases, only one user could be on the system at a time. Only larger BBSes with multiple phone lines using specialized hardware, multitasking software, or a LAN connecting multiple computers, could host multiple simultaneous users. The first BBSes used homebrew software, quite often written or customized by the system operators themselves, running on early S-100 bus microcomputer systems such as the Altair 8800, IMSAI 8080 and Cromemco under the CP/M operating system. Soon after, BBS software was being written for all of the major home computer systems of the late 1970s erathe Apple II, Atari 8-bit family, Commodore and TRS-80 being some of the most popular. A few years later, in 1981, IBM introduced the first DOS based IBM PC, and due to the overwhelming popularity of PCs and their clones, DOS soon became the operating system on which the majority of BBS programs were run. RBBS-PC, ported over from the CP/M world, and Fido BBS, developed by Tom Jennings (who later founded FidoNet) were the first notable DOS BBS programs. Many successful commercial BBS programs were developed for DOS, such as PCBoard BBS, RemoteAccess BBS, Magpie and Wildcat! BBS. Some popular freeware BBS programs for DOS included Telegard BBS and Renegade BBS, which both had early origins from leaked WWIV BBS source code. There were several dozen other BBS programs developed over the DOS era, and many were released under the shareware concept, while some were released as freeware including iniquity. BBS systems on other systems remained popular, especially home computers, largely because they catered to the audience of users running those machines. The ubiquitous Commodore 64 (introduced in 1982) was a common platform in the 1980s. Popular commercial BBS programs were Blue Board, Ivory BBS, Color64 and CNet 64. In the early 1990s, a small number of BBSes were also running on the Commodore Amiga. Popular BBS software for the Amiga were ABBS, Amiexpress, C-Net, StormforceBBS, Infinity and Tempest. There was also a small faction of devoted Atari BBSes that used the Atari 800, then the 800XL, and eventually the 1040ST. The earlier machines generally lacked hard drive capabilities, which limited them primarily to messaging. MS-DOS continued to be the most popular operating system for BBS use up until the mid-1990s, and in the early years, most multi-node BBSes were running under a DOS based multitasker such as DESQview or consisted of multiple computers connected via a LAN. In the late 1980s, a handful of BBS developers implemented multitasking communications routines inside their software, allowing multiple phone lines and users to connect to the same BBS computer. These included Galacticomm's MajorBBS (later WorldGroup), eSoft The Bread Board System (TBBS), and Falken. Other popular BBS's were Maximus and Opus, with some associated applications such as BinkleyTerm being based on characters from the Berkley Breathed cartoon strip of Bloom County. Though most BBS software had been written in BASIC or Pascal (with some low-level routines written in assembly language), the C language was starting to gain popularity. By 1995, many of the DOS-based BBSes had begun switching to modern multitasking operating systems, such as OS/2, Windows 95, and Linux. One of the first graphics-based BBS applications was Excalibur BBS with low-bandwidth applications that required its own client for efficiency. This led to one of the earliest implementations of Electronic Commerce in 1996 with replication of partner stores around the globe. TCP/IP networking allowed most of the remaining BBSes to evolve and include Internet hosting capabilities. Recent BBS software, such as Synchronet, Mystic BBS, EleBBS, DOC, Magpie or Wildcat! BBS, provide access using the Telnet protocol rather than dialup, or by using legacy DOS-based BBS software with a FOSSIL-to-Telnet redirector such as NetFoss. Presentation BBSes were generally text-based, rather than GUI-based, and early BBSes conversed using the simple ASCII character set. However, some home computer manufacturers extended the ASCII character set to take advantage of the advanced color and graphics capabilities of their systems. BBS software authors included these extended character sets in their software, and terminal program authors included the ability to display them when a compatible system was called. Atari's native character set was known as ATASCII, while most Commodore BBSes supported PETSCII. PETSCII was also supported by the nationwide online service Quantum Link. The use of these custom character sets was generally incompatible between manufacturers. Unless a caller was using terminal emulation software written for, and running on, the same type of system as the BBS, the session would simply fall back to simple ASCII output. For example, a Commodore 64 user calling an Atari BBS would use ASCII rather than the native character set of either. As time progressed, most terminal programs began using the ASCII standard, but could use their native character set if it was available. COCONET, a BBS system made by Coconut Computing, Inc., was released in 1988 and only supported a GUI (no text interface was initially available but eventually became available around 1990), and worked in EGA/VGA graphics mode, which made it stand out from text-based BBS systems. COCONET's bitmap and vector graphics and support for multiple type fonts were inspired by the PLATO system, and the graphics capabilities were based on what was available in the Borland Graphics Interface library. A competing approach called Remote Imaging Protocol (RIP) emerged and was promoted by Telegrafix in the early to mid-1990s but it never became widespread. A teletext technology called NAPLPS was also considered, and although it became the underlying graphics technology behind the Prodigy service, it never gained popularity in the BBS market. There were several GUI-based BBSes on the Apple Macintosh platform, including TeleFinder and FirstClass, but these were mostly confined to the Mac market. In the UK, the BBC Micro based OBBS software, available from Pace for use with their modems, optionally allowed for color and graphics using the Teletext based graphics mode available on that platform. Other systems used the Viewdata protocols made popular in the UK by British Telecom's Prestel service, and the on-line magazine Micronet 800 whom were busy giving away modems with their subscriptions. Over time, terminal manufacturers started to support ANSI X3.64 in addition to or instead of proprietary terminal control codes, e.g., color, cursor positioning. The most popular form of online graphics was ANSI art, which combined the IBM Extended ASCII character set's blocks and symbols with ANSI escape sequences to allow changing colors on demand, provide cursor control and screen formatting, and even basic musical tones. During the late 1980s and early 1990s, most BBSes used ANSI to make elaborate welcome screens, and colorized menus, and thus, ANSI support was a sought-after feature in terminal client programs. The development of ANSI art became so popular that it spawned an entire BBS "artscene" subculture devoted to it. The Amiga Skyline BBS software was the first in 1987 featuring a script markup language communication protocol called Skypix which was capable of giving the user a complete graphical interface, featuring rich graphics, changeable fonts, mouse-controlled actions, animations and sound. Today, most BBS software that is still actively supported, such as Worldgroup, Wildcat! BBS and Citadel/UX, is Web-enabled, and the traditional text interface has been replaced (or operates concurrently) with a Web-based user interface. For those more nostalgic for the true BBS experience, one can use NetSerial (Windows) or DOSBox (Windows/*nix) to redirect DOS COM port software to telnet, allowing them to connect to Telnet BBSes using 1980s and 1990s era modem terminal emulation software, like Telix, Terminate, Qmodem and Procomm Plus. Modern 32-bit terminal emulators such as mTelnet and SyncTerm include native telnet support. Content and access Since most early BBSes were run by computer hobbyists, they were typically technical in topic, with user communities revolving around hardware and software discussions. As the BBS phenomenon grew, so did the popularity of special interest boards. Bulletin Board Systems could be found for almost every hobby and interest. Popular interests included politics, religion, music, dating, and alternative lifestyles. Many system operators also adopted a theme in which they customized their entire BBS (welcome screens, prompts, menus, and so on) to reflect that theme. Common themes were based on fantasy, or were intended to give the user the illusion of being somewhere else, such as in a sanatorium, wizard's castle, or on a pirate ship. In the early days, the file download library consisted of files that the system operators obtained themselves from other BBSes and friends. Many BBSes inspected every file uploaded to their public file download library to ensure that the material did not violate copyright law. As time went on, shareware CD-ROMs were sold with up to thousands of files on each CD-ROM. Small BBSes copied each file individually to their hard drive. Some systems used a CD-ROM drive to make the files available. Advanced BBSes used Multiple CD-ROM disc changer units that switched 6 CD-ROM disks on demand for the caller(s). Large systems used all 26 DOS drive letters with multi-disk changers housing tens of thousands of copyright-free shareware or freeware files available to all callers. These BBSes were generally more family-friendly, avoiding the seedier side of BBSes. Access to these systems varied from single to multiple modem lines with some requiring little or no confirmed registration. Some BBSes, called elite, WaReZ or pirate boards, were exclusively used for distributing cracked software, phreaking, and other questionable or unlawful content. These BBSes often had multiple modems and phone lines, allowing several users to upload and download files at once. Most elite BBSes used some form of new user verification, where new users would have to apply for membership and attempt to prove that they were not a law enforcement officer or a lamer. The largest elite boards accepted users by invitation only. Elite boards also spawned their own subculture and gave rise to the slang known today as leetspeak. Another common type of board was the support BBS run by a manufacturer of computer products or software. These boards were dedicated to supporting users of the company's products with question and answer forums, news and updates, and downloads. Most of them were not a free call. Today, these services have moved to the Web. Some general-purpose Bulletin Board Systems had special levels of access that were given to those who paid extra money, uploaded useful files or knew the system operator personally. These specialty and pay BBSes usually had something unique to offer their users, such as large file libraries, warez, pornography, chat rooms or Internet access. Pay BBSes such as The WELL and Echo NYC (now Internet forums rather than dial-up), ExecPC, PsudNetwork and MindVox (which folded in 1996) were admired for their tight-knit communities and quality discussion forums. However, many free BBSes also maintained close knit communities, and some even had annual or bi-annual events where users would travel great distances to meet face-to-face with their on-line friends. These events were especially popular with BBSes that offered chat rooms. Some of the BBSes that provided access to illegal content faced opposition. On July 12, 1985, in conjunction with a credit card fraud investigation, the Middlesex County, New Jersey Sheriff's department raided and seized The Private Sector BBS, which was the official BBS for grey hat hacker quarterly 2600 Magazine at the time. The notorious Rusty n Edie's BBS, in Boardman, Ohio, was raided by the FBI in January 1993 for trading unlicensed software, and later sued by Playboy for copyright infringement in November 1997. In Flint, Michigan, a 21-year-old man was charged with distributing child pornography through his BBS in March 1996. Networks Most early BBSes operated as individual systems. Information contained on that BBS never left the system, and users would only interact with the information and user community on that BBS alone. However, as BBSes became more widespread, there evolved a desire to connect systems together to share messages and files with distant systems and users. The largest such network was FidoNet. As is it was prohibitively expensive for the hobbyist system operator to have a dedicated connection to another system, FidoNet was developed as a store and forward network. Private email (Netmail), public message boards (Echomail) and eventually even file attachments on a FidoNet-capable BBS would be bundled into one or more archive files over a set time interval. These archive files were then compressed with ARC or ZIP and forwarded to (or polled by) another nearby node or hub via a dialup Xmodem session. Messages would be relayed around various FidoNet hubs until they were eventually delivered to their destination. The hierarchy of FidoNet BBS nodes, hubs, and zones was maintained in a routing table called a Nodelist. Some larger BBSes or regional FidoNet hubs would make several transfers per day, some even to multiple nodes or hubs, and as such, transfers usually occurred at night or in the early morning when toll rates were lowest. In Fido's heyday, sending a Netmail message to a user on a distant FidoNet node, or participating in an Echomail discussion could take days, especially if any FidoNet nodes or hubs in the message's route only made one transfer call per day. FidoNet was platform-independent and would work with any BBS that was written to use it. BBSes that did not have integrated FidoNet capability could usually add it using an external FidoNet front-end mailer such as SEAdog, FrontDoor, BinkleyTerm, InterMail or D'Bridge, and a mail processor such as FastEcho or Squish. The front-end mailer would conduct the periodic FidoNet transfers, while the mail processor would usually run just before and just after the mailer ran. This program would scan for and pack up new outgoing messages, and then unpack, sort and "toss" the incoming messages into a BBS user's local email box or into the BBS's local message bases reserved for Echomail. As such, these mail processors were commonly called "scanner/tosser/packers". Many other BBS networks followed the example of FidoNet, using the same standards and the same software. These were called FidoNet Technology Networks (FTNs). They were usually smaller and targeted at selected audiences. Some networks used QWK doors, and others such as RelayNet (RIME) and WWIVnet used non-Fido software and standards. Before commercial Internet access became common, these networks of BBSes provided regional and international e-mail and message bases. Some even provided gateways, such as UFGATE, by which members could send and receive e-mail to and from the Internet via UUCP, and many FidoNet discussion groups were shared via gateway to Usenet. Elaborate schemes allowed users to download binary files, search gopherspace, and interact with distant programs, all using plain-text e-mail. As the volume of FidoNet Mail increased and newsgroups from the early days of the Internet became available, satellite data downstream services became viable for larger systems. The satellite service provided access to FidoNet and Usenet newsgroups in large volumes at a reasonable fee. By connecting a small dish and receiver, a constant downstream of thousands of FidoNet and Usenet newsgroups could be received. The local BBS only needed to upload new outgoing messages via the modem network back to the satellite service. This method drastically reduced phone data transfers while dramatically increasing the number of message forums. FidoNet is still in use today, though in a much smaller form, and many Echomail groups are still shared with Usenet via FidoNet to Usenet gateways. Widespread abuse of Usenet with spam and pornography has led to many of these FidoNet gateways to cease operation completely. Shareware and freeware Much of the shareware movement was started via user distribution of software through BBSes. A notable example was Phil Katz's PKARC (and later PKZIP, using the same ".zip" algorithm that WinZip and other popular archivers now use); also other concepts of software distribution like freeware, postcardware like JPEGview and donationware like Red Ryder for the Macintosh first appeared on BBS sites. Doom from id Software and nearly all Apogee Software games were distributed as shareware (Apogee is, in fact, credited for adding an order form to a shareware demo). The Internet has largely erased the distinction of sharewaremost users now download the software directly from the developer's website rather than receiving it from another BBS user 'sharing' it. Today shareware is commonly used to mean electronically-distributed software from a small developer. Many commercial BBS software companies that continue to support their old BBS software products switched to the shareware model or made it entirely free. Some companies were able to make the move to the Internet and provide commercial products with BBS capabilities. Features A classic BBS had: A computer One or more modems One or more phone lines, with more allowing for increased concurrent users A BBS software package A sysop – system operator A user community The BBS software usually provides: Menu systems One or more message bases Uploading and downloading of message packets in QWK format using XMODEM, YMODEM or ZMODEM File areas Live viewing of all caller activity by the system operator Voting – opinion booths Statistics on message posters, top uploaders / downloaders Online games (usually single player or only a single active player at a given time) A doorway to third-party online games Usage auditing capabilities Multi-user chat (only possible on multi-line BBSes) Internet email (more common in later Internet-connected BBSes) Networked message boards Most modern BBSes allow telnet access over the Internet using a telnet server and a virtual FOSSIL driver.

Symphony No. 9 (Beethoven)

The Symphony No. 9 in D minor, Op. 125, is a choral symphony, the final complete symphony by Ludwig van Beethoven, composed between 1822 and 1824. It was first performed in Vienna on 7 May 1824. The symphony is regarded by many critics and musicologists as a masterpiece of Western classical music and one of the supreme achievements in the entire history of music. One of the best-known works in common practice music, it stands as one of the most frequently performed symphonies in the world. The Ninth was the first example of a major composer scoring vocal parts in a symphony. The final (4th) movement of the symphony features four vocal soloists and a chorus in the parallel modulated key of D major. The text was adapted from the "An die Freude (Ode to Joy)", a poem written by Friedrich Schiller in 1785 and revised in 1803, with additional text written by Beethoven. In 2001, Beethoven's original, hand-written manuscript of the score, held by the Berlin State Library, was added to the Memory of the World Programme Heritage list established by the United Nations, becoming the first musical score so designated. History Composition The Philharmonic Society of London originally commissioned the symphony in 1817. Preliminary sketches (rough outlines) for the work were also made that year, with the key set as D minor and vocal participation also forecast. The main composition work was done between autumn 1822 and the completion of the autograph in February 1824. The symphony emerged from other pieces by Beethoven that, while completed works in their own right, are also in some sense forerunners of the future symphony. The 1808 Choral Fantasy, Op. 80, basically a piano concerto movement, brings in a choir and vocal soloists near the end for the climax. The vocal forces sing a theme first played instrumentally, and this theme is reminiscent of the corresponding theme in the Ninth Symphony. Going further back, an earlier version of the Choral Fantasy theme is found in the song "Gegenliebe" (Returned Love) for piano and high voice, which dates from before 1795. According to Robert W. Gutman, Mozart's Offertory in D minor, "Misericordias Domini", K. 222, written in 1775, contains a melody that foreshadows "Ode to Joy". Premiere Although most of his major works had been premiered in Vienna, Beethoven was keen to have his latest composition performed in Berlin as soon as possible after finishing it, as he thought that musical taste in Vienna had become dominated by Italian composers such as Rossini. When his friends and financiers heard this, they urged him to premiere the symphony in Vienna in the form of a petition signed by a number of prominent Viennese music patrons and performers. Beethoven was flattered by the adoration of Vienna, so the Ninth Symphony was premiered on 7 May 1824 in the Theater am Kärntnertor in Vienna along with the overture The Consecration of the House () and three parts of the Missa solemnis (the Kyrie, Credo, and Agnus Dei). This was the composer's first onstage appearance in 12 years; the hall was packed with an eager and curious audience and a number of musicians and figures in Vienna including Franz Schubert, Carl Czerny, and the Austrian chancellor Klemens von Metternich. The premiere of Symphony No. 9 involved the largest orchestra ever assembled by Beethoven and required the combined efforts of the Kärntnertor house orchestra, the Vienna Music Society (Gesellschaft der Musikfreunde), and a select group of capable amateurs. While no complete list of premiere performers exists, many of Vienna's most elite performers are known to have participated. The soprano and alto parts were sung by two famous young singers: Henriette Sontag and Caroline Unger. German soprano Henriette Sontag was 18 years old when Beethoven personally recruited her to perform in the premiere of the Ninth. Also personally recruited by Beethoven, 20-year-old contralto Caroline Unger, a native of Vienna, had gained critical praise in 1821 appearing in Rossini's Tancredi. After performing in Beethoven's 1824 premiere, Unger then found fame in Italy and Paris. Italian composers Donizetti and Bellini were known to have written roles specifically for her voice. Anton Haizinger and Joseph Seipelt sang the tenor and bass/baritone parts, respectively. Although the performance was officially directed by Michael Umlauf, the theatre's Kapellmeister, Beethoven shared the stage with him. However, two years earlier, Umlauf had watched as the composer's attempt to conduct a dress rehearsal for a revision of his opera Fidelio ended in disaster. So this time, he instructed the singers and musicians to ignore the almost completely deaf Beethoven. At the beginning of every part, Beethoven, who sat by the stage, gave the tempos. He was turning the pages of his score and beating time for an orchestra he could not hear. There are a number of anecdotes concerning the premiere of the Ninth. Based on the testimony of some of the participants, there are suggestions that the symphony was under-rehearsed (there were only two full rehearsals) and somewhat uneven in execution. On the other hand, the premiere was a great success. In any case, Beethoven was not to blame, as violinist Joseph Böhm recalled:Beethoven himself conducted, that is, he stood in front of a conductor's stand and threw himself back and forth like a madman. At one moment he stretched to his full height, at the next he crouched down to the floor, he flailed about with his hands and feet as though he wanted to play all the instruments and sing all the chorus parts. —The actual direction was in [Louis] Duport's hands; we musicians followed his baton only. Reportedly, the scherzo was completely interrupted at one point by applause. Either at the end of the scherzo or the end of the symphony (testimonies differ), Beethoven was several bars off and still conducting; the contralto Caroline Unger walked over and gently turned Beethoven around to accept the audience's cheers and applause. According to the critic for the Theater-Zeitung, "the public received the musical hero with the utmost respect and sympathy, listened to his wonderful, gigantic creations with the most absorbed attention and broke out in jubilant applause, often during sections, and repeatedly at the end of them." The audience acclaimed him through standing ovations five times; there were handkerchiefs in the air, hats, and raised hands, so that Beethoven, who they knew could not hear the applause, could at least see the ovations. Editions The first German edition was printed by B. Schott's Söhne (Mainz) in 1826. The Breitkopf & Härtel edition dating from 1864 has been used widely by orchestras. In 1997, Bärenreiter published an edition by Jonathan Del Mar. According to Del Mar, this edition corrects nearly 3,000 mistakes in the Breitkopf edition, some of which were "remarkable". David Levy, however, criticized this edition, saying that it could create "quite possibly false" traditions. Breitkopf also published a new edition by Peter Hauschild in 2005. Instrumentation The symphony is scored for the following orchestra. These are by far the largest forces needed for any Beethoven symphony; at the premiere, Beethoven augmented them further by assigning two players to each wind part. Woodwinds 2 Flutes 2 Oboes 2 Clarinets in A, B and C 2 Bassoons Brass 4 Horns in D, B and E 2 Trumpets in D and B Percussion Timpani Bass drum (fourth movement only) Triangle (fourth movement only) Cymbals (fourth movement only) Soprano solo Alto solo Tenor solo Strings Violins I, II Violas Cellos Double basses Form The symphony is in four movements. The structure of each movement is as follows: {| class="wikitable" ! style="background: Silver" |Tempo marking ! style="background: Silver" |Meter ! style="background: Silver" |Key |- ! colspan="3" align="center" |Movement I |- |Allegro ma non troppo, un poco maestoso = 88 | align="center" | | align="center" | d |- ! colspan="3" align="center" |Movement II |- |Molto vivace = 116 | align="center" | | align="center" | d |- |Tempo#Basic_tempo_markings|Presto = 116 | align="center" | | align="center" | D |- |Molto vivace | align="center" | | align="center" | d |- |Presto | align="center" | | align="center" | D |- ! colspan="3" align="center" |Movement III |- |Tempo#Basic_tempo_markings|Adagio molto e cantabile = 60 | align="center" | | align="center" | B |- |Tempo#Basic_tempo_markings|Andante moderato = 63 | align="center" | | align="center" | D |- |Tempo I | align="center" | | align="center" | B |- |Andante moderato | align="center" | | align="center" | G |- |Adagio | align="center" | | align="center" | E |- |Lo stesso tempo | align="center" | | align="center" | B |- ! colspan="3" align="center" |Movement IV |- |Presto = 96 | align="center" | | align="center" | d |- |Allegro assai = 80 | align="center" | | align="center" | D |- |Presto ("O Freunde") | align="center" | | align="center" | d |- |Allegro assai ("Freude, schöner Götterfunken") | align="center" | | align="center" | D |- |Alla marcia; Allegro assai vivace = 84 ("Froh, wie seine Sonnen") | align="center" | | align="center" | B |- |Andante maestoso = 72 ("Seid umschlungen, Millionen!") | align="center" | | align="center" | G |- |Allegro energico, sempre ben marcato = 84("Freude, schöner Götterfunken" – "Seid umschlungen, Millionen!") | align="center" | | align="center" | D |- |Allegro ma non tanto = 120 ("Freude, Tochter aus Elysium!") | align="center" | | align="center" | D |- |Tempo#Basic_tempo_markings|Prestissimo = 132 ("Seid umschlungen, Millionen!") | align="center" | | align="center" | D |- |} Beethoven changes the usual pattern of Classical symphonies in placing the scherzo movement before the slow movement (in symphonies, slow movements are usually placed before scherzi). This was the first time he did this in a symphony, although he had done so in some previous works, including the String Quartet Op. 18 no. 5, the "Archduke" piano trio Op. 97, the Hammerklavier piano sonata Op. 106. And Haydn, too, had used this arrangement in a number of his own works such as the String Quartet No. 30 in E major, as did Mozart in three of the Haydn Quartets and the G minor String Quintet. I. Allegro ma non troppo, un poco maestoso The first movement is in sonata form without an exposition repeat. It begins with open fifths (A and E) played pianissimo by tremolo strings, steadily building up until the first main theme in D minor at bar 17. The opening, with its perfect fifth quietly emerging, resembles the sound of an orchestra tuning up. At the outset of the recapitulation (which repeats the main melodic themes) in bar 301, the theme returns, this time played fortissimo and in D major, rather than D minor. The movement ends with a massive coda that takes up nearly a quarter of the movement, as in Beethoven's Third and Fifth Symphonies. A typical performance lasts about 15 minutes. II. Molto vivace The second movement is a scherzo and trio. Like the first movement, the scherzo is in D minor, with the introduction bearing a passing resemblance to the opening theme of the first movement, a pattern also found in the Hammerklavier piano sonata, written a few years earlier. At times during the piece, Beethoven specifies one downbeat every three bars—perhaps because of the fast tempo—with the direction ritmo di tre battute (rhythm of three beats) and one beat every four bars with the direction ritmo di quattro battute (rhythm of four beats). Normally, a scherzo is in triple time. Beethoven wrote this piece in triple time but punctuated it in a way that, when coupled with the tempo, makes it sound as if it is in quadruple time. While adhering to the standard compound ternary design (three-part structure) of a dance movement (scherzo-trio-scherzo or minuet-trio-minuet), the scherzo section has an elaborate internal structure; it is a complete sonata form. Within this sonata form, the first group of the exposition (the statement of the main melodic themes) starts out with a fugue in D minor on the subject below. For the second subject, it modulates to the unusual key of C major. The exposition then repeats before a short development section, where Beethoven explores other ideas. The recapitulation (repeating of the melodic themes heard in the opening of the movement) further develops the exposition's themes, also containing timpani solos. A new development section leads to the repeat of the recapitulation, and the scherzo concludes with a brief codetta. The contrasting trio section is in D major and in duple time. The trio is the first time the trombones play. Following the trio, the second occurrence of the scherzo, unlike the first, plays through without any repetition, after which there is a brief reprise of the trio, and the movement ends with an abrupt coda. The duration of the movement is about 11 minutes, but this may vary depending on whether two (frequently omitted) repeats are played. III. Adagio molto e cantabile The third movement is a lyrical, slow movement in B major—a minor sixth away from the symphony's main key of D minor. It is in a double variation form, with each pair of variations progressively elaborating the rhythm and melodic ideas. The first variation, like the theme, is in time, the second in . The variations are separated by passages in , the first in D major, the second in G major, the third in E major, and the fourth in B major. The final variation is twice interrupted by episodes in which loud fanfares from the full orchestra are answered by octaves by the first violins. A prominent French horn solo is assigned to the fourth player. A performance lasts about 16 minutes. IV. Finale The choral finale is Beethoven's musical representation of universal brotherhood based on the "Ode to Joy" theme and is in theme and variations form. The movement starts with an introduction in which musical material from each of the preceding three movements—though none are literal quotations of previous music—are successively presented and then dismissed by instrumental recitatives played by the low strings. Following this, the "Ode to Joy" theme is finally introduced by the cellos and double basses. After three instrumental variations on this theme, the human voice is presented for the first time in the symphony by the baritone soloist, who sings words written by Beethoven himself: ''O Freunde, nicht diese Töne!' Sondern laßt uns angenehmere anstimmen, und freudenvollere.'' ("Oh friends, not these sounds! Let us instead strike up more pleasing and more joyful ones!"). At about 24 minutes in length, the last movement is the longest of the four movements. Indeed, it is longer than some entire symphonies of the Classical era. Its form has been disputed by musicologists, as Nicholas Cook explains: Cook gives the following table describing the form of the movement: In line with Cook's remarks, Charles Rosen characterizes the final movement as a symphony within a symphony, played without interruption. This "inner symphony" follows the same overall pattern as the Ninth Symphony as a whole, with four "movements": Theme and variations with slow introduction. The main theme, first in the cellos and basses, is later recapitulated by voices. Scherzo in a military style. It begins at Alla marcia (bar 331 - 594) and concludes with a variation of the main theme with chorus. Slow section with a new theme on the text "Seid umschlungen, Millionen!" It begins at Andante maestoso (bar 595–654). Fugato finale on the themes of the first and third "movements". It begins at Allegro energico (bar 655–762), and two canons on main theme and "Seid unschlungen, Millionen!" respectively. It begins at Allegro ma non tanto (bar 763–940). Rosen notes that the movement can also be analysed as a set of variations and simultaneously as a concerto sonata form with double exposition (with the fugato acting both as a development section and the second tutti of the concerto). Text of the fourth movement The text is largely taken from Friedrich Schiller's "Ode to Joy", with a few additional introductory words written specifically by Beethoven (shown in italics). The text, without repeats, is shown below, with a translation into English. The score includes many repeats. For the full libretto, including all repetitions, see German Wikisource. Towards the end of the movement, the choir sings the last four lines of the main theme, concluding with "Alle Menschen" before the soloists sing for one last time the song of joy at a slower tempo. The chorus repeats parts of "Seid umschlungen, Millionen!", then quietly sings, "Tochter aus Elysium", and finally, "Freude, schöner Götterfunken, Götterfunken!". Reception The symphony was dedicated to the King of Prussia, Frederick William III. Music critics almost universally consider the Ninth Symphony one of Beethoven's greatest works, and among the greatest musical works ever written. The finale, however, has had its detractors: "[e]arly critics rejected [the finale] as cryptic and eccentric, the product of a deaf and ageing composer." Verdi admired the first three movements but lamented what he saw as the bad writing for the voices in the last movement: Performance challenges Metronome markings Conductors in the historically informed performance movement, notably Roger Norrington, have used Beethoven's suggested tempos, to mixed reviews. Benjamin Zander has made a case for following Beethoven's metronome markings, both in writing and in performances with the Boston Philharmonic Orchestra and Philharmonia Orchestra of London. Beethoven's metronome still exists and was tested and found accurate, but the original heavy weight (whose position is vital to its accuracy) is missing and many musicians have considered his metronome marks to be unacceptably high. Re-orchestrations and alterations A number of conductors have made alterations in the instrumentation of the symphony. Notably, Richard Wagner doubled many woodwind passages, a modification greatly extended by Gustav Mahler, who revised the orchestration of the Ninth to make it sound like what he believed Beethoven would have wanted if given a modern orchestra. Wagner's Dresden performance of 1864 was the first to place the chorus and the solo singers behind the orchestra as has since become standard; previous conductors placed them between the orchestra and the audience. 2nd bassoon doubling basses in the finale Beethoven's indication that the 2nd bassoon should double the basses in bars 115–164 of the finale was not included in the Breitkopf & Härtel parts, though it was included in the full score. Notable performances and recordings The British premiere of the symphony was presented on 21 March 1825 by its commissioners, the Philharmonic Society of London, at its Argyll Rooms conducted by Sir George Smart and with the choral part sung in Italian. The American premiere was presented on 20 May 1846 by the newly formed New York Philharmonic at Castle Garden (in an attempt to raise funds for a new concert hall), conducted by the English-born George Loder, with the choral part translated into English for the first time. Leopold Stokowski's 1934 Philadelphia Orchestra and 1941 NBC Symphony Orchestra recordings also used English lyrics in the fourth movement. Richard Wagner inaugurated his Bayreuth Festspielhaus by conducting the Ninth; since then it is traditional to open each Bayreuth Festival with a performance of the Ninth. Following the festival's temporary suspension after World War II, Wilhelm Furtwängler and the Bayreuth Festival Orchestra reinaugurated it with a performance of the Ninth. Leonard Bernstein conducted a version of the Ninth Symphony at the Konzerthaus Berlin with (Freedom) replacing (Joy), to celebrate the fall of the Berlin Wall during Christmas of 1989. This concert was performed by an orchestra and chorus made up of many nationalities: from East and West Germany, the Bavarian Radio Symphony Orchestra and Chorus, the Chorus of the Berlin Radio Symphony Orchestra, and members of the Sächsische Staatskapelle Dresden, the Philharmonischer Kinderchor Dresden (Philharmonic Children's Choir Dresden); from the Soviet Union, members of the orchestra of the Kirov Theatre; from the United Kingdom, members of the London Symphony Orchestra; from the US, members of the New York Philharmonic; and from France, members of the Orchestre de Paris. Soloists were June Anderson, soprano, Sarah Walker, mezzo-soprano, Klaus König, tenor, and Jan-Hendrik Rootering, bass. This was Bernstein's final performance of Beethoven's Ninth Symphony; he died less than a year later, in October 1990. In 1998, Japanese conductor Seiji Ozawa conducted the fourth movement for the 1998 Winter Olympics opening ceremony, with six different choirs simultaneously singing from Japan, Germany, South Africa, China, the United States, and Australia. In 1923, the first complete recording of Beethoven's Ninth Symphony was made by the acoustic recording process and conducted by Bruno Seidler-Winkler. The recording was issued by Deutsche Grammophon in Germany; the records were issued in the United States on the Vocalion label. The first electrical recording of the Ninth was recorded in England in 1926, with Felix Weingartner conducting the London Symphony Orchestra, issued by Columbia Records. The first complete American recording was made by RCA Victor in 1934 with Leopold Stokowski conducting the Philadelphia Orchestra. Since the late 20th century, the Ninth has been recorded regularly by period performers, including Roger Norrington, Christopher Hogwood, and Sir John Eliot Gardiner. The BBC Proms Youth Choir performed the piece alongside Georg Solti's UNESCO World Orchestra for Peace at the Royal Albert Hall during the 2018 Proms at Prom 9, titled "War & Peace" as a commemoration to the centenary of the end of World War One. At 79 minutes, one of the longest Ninths recorded is Karl Böhm's, conducting the Vienna Philharmonic in 1981 with Jessye Norman and Plácido Domingo among the soloists. Influence Many later composers of the Romantic period and beyond were influenced by the Ninth Symphony. An important theme in the finale of Johannes Brahms' Symphony No. 1 in C minor is related to the "Ode to Joy" theme from the last movement of Beethoven's Ninth Symphony. When this was pointed out to Brahms, he is reputed to have retorted "Any fool can see that!" Brahms's first symphony was, at times, both praised and derided as "Beethoven's Tenth". The Ninth Symphony influenced the forms that Anton Bruckner used for the movements of his symphonies. His Symphony No. 3 is in the same key (D minor) as Beethoven's 9th and makes substantial use of thematic ideas from it. The slow movement of Bruckner's Symphony No. 7 uses the A–B–A–B–A form found in the 3rd movement of Beethoven's piece and takes various figurations from it. In the opening notes of the third movement of his Symphony No. 9 (From the New World), Antonín Dvořák pays homage to the scherzo of Beethoven's Ninth Symphony with his falling fourths and timpani strokes. Béla Bartók borrowed the opening motif of the scherzo from Beethoven's Ninth Symphony to introduce the second movement (scherzo) in his own Four Orchestral Pieces, Op. 12 (Sz 51). Michael Tippett in his Third Symphony (1972) quotes the opening of the finale of Beethoven's Ninth and then criticises the utopian understanding of the brotherhood of man as expressed in the Ode to Joy and instead stresses man's capacity for both good and evil. In the film The Pervert's Guide to Ideology, the philosopher Slavoj Žižek comments on the use of the Ode by Nazism, Bolshevism, the Chinese Cultural Revolution, the East-West German Olympic team, Southern Rhodesia, Abimael Guzmán (leader of the Shining Path), and the Council of Europe and the European Union. Compact disc format One legend is that the compact disc was deliberately designed to have a 74-minute playing time so that it could accommodate Beethoven's Ninth Symphony. Kees Immink, Philips' chief engineer, who developed the CD, recalls that a commercial tug-of-war between the development partners, Sony and Philips, led to a settlement in a neutral 12-cm diameter format. The 1951 performance of the Ninth Symphony conducted by Furtwängler was brought forward as the perfect excuse for the change, and was put forth in a Philips news release celebrating the 25th anniversary of the Compact Disc as the reason for the 74-minute length. TV theme music The Huntley–Brinkley Report used the opening to the second movement as its theme music during the run of the program on NBC from 1956 until 1970. The theme was taken from the 1952 RCA Victor recording of the Ninth Symphony by the NBC Symphony Orchestra conducted by Arturo Toscanini. A synthesized version of the opening bars of the second movement were also used as the theme for Countdown with Keith Olbermann on MSNBC and Current TV. A rock guitar version of the "Ode to Joy" theme was used as the theme for Suddenly Susan in its first season. Use as (national) anthem During the division of Germany in the Cold War, the "Ode to Joy" segment of the symphony was played in lieu of a national anthem at the Olympic Games for the United Team of Germany between 1956 and 1968. In 1972, the musical backing (without the words) was adopted as the Anthem of Europe by the Council of Europe and subsequently by the European Communities (now the European Union) in 1985. Also, the "Ode to Joy" was used as the national anthem of Rhodesia between 1974 and 1979, as "Rise, O Voices of Rhodesia". During the early 1990s, South Africa used an instrumental version of "Ode to Joy" in lieu of its national anthem at the time "Die Stem van Suid-Afrika" at sporting events, though it was never actually adopted as an official national anthem. Use as a hymn melody In 1907, the Presbyterian pastor Henry van Dyke Jr. wrote the hymn "Joyful, Joyful, we adore thee" while staying at Williams College. The hymn is commonly sung in English-language churches to the "Ode to Joy" melody from this symphony. Year-end tradition The German workers' movement began the tradition of performing the Ninth Symphony on New Year's Eve in 1918. Performances started at 11 p.m. so that the symphony's finale would be played at the beginning of the new year. This tradition continued during the Nazi period and was also observed by East Germany after the war. The Ninth Symphony is traditionally performed throughout Japan at the end of the year. In December 2009, for example, there were 55 performances of the symphony by various major orchestras and choirs in Japan. It was introduced to Japan during World War I by German prisoners held at the Bandō prisoner-of-war camp. Japanese orchestras, notably the NHK Symphony Orchestra, began performing the symphony in 1925 and during World War II; the Imperial government promoted performances of the symphony, including on New Year's Eve. In an effort to capitalize on its popularity, orchestras and choruses undergoing economic hard times during Japan's reconstruction performed the piece at year's end. In the 1960s, these year-end performances of the symphony became more widespread, and included the participation of local choirs and orchestras, firmly establishing a tradition that continues today. Some of these performances feature massed choirs of up to 10,000 singers. WQXR-FM, a classical radio station serving the New York metropolitan area, ends every year with a countdown of the pieces of classical music most requested in a survey held every December; though any piece could win the place of honor and thus welcome the New Year, i.e. play through midnight on January 1, Beethoven's Choral has won in every year on record. Other choral symphonies Prior to Beethoven's ninth, symphonies had not used choral forces and the piece thus established the genre of choral symphony. Numbered choral symphonies as part of a cycle of otherwise instrumental works have subsequently been written by numerous composers, including Felix Mendelssohn, Gustav Mahler, Ralph Vaughan Williams and Charles Ives among many others. Other ninth symphonies The scale and influence of Beethoven's ninth led later composers to ascribe a special significance to their own ninth symphonies, which may have contributed to the cultural phenomenon known as the curse of the ninth. A number of other composers' ninth symphonies also employ a chorus, such as those by Kurt Atterberg, Mieczysław Weinberg, Edmund Rubbra, Hans Werner Henze, and Robert Kyr. Anton Bruckner had not originally intended his unfinished ninth symphony to feature choral forces, however the use of his choral Te Deum in lieu of the uncompleted Finale was supposedly sanctioned by the composer. Dmitri Shostakovich had originally intended his Ninth Symphony to be a large work with chorus and soloists, although the symphony as it eventually appeared was a relatively short work without vocal forces. Of his own Ninth Symphony, George Lloyd wrote: "When a composer has written eight symphonies he may find that the horizon has been blacked out by the overwhelming image of Beethoven and his one and only Ninth. There are other very good No. 5s and No. 3s, for instance, but how can one possibly have the temerity of trying to write another Ninth Symphony?" Niels Gade composed only eight symphonies, despite living for another twenty years after completing the eighth. He is believed to have replied, when asked why he did not compose another symphony, "There is only one ninth", in reference to Beethoven.

Bangladesh

Bangladesh (; , ), officially the People's Republic of Bangladesh, is a country in South Asia. It is the eighth-most-populous and among the most densely populated countries, with a population of around 170 million in an area of . Bangladesh shares land borders with India to the west, north, and east, and Myanmar to the southeast; to the south it has a coastline along the Bay of Bengal. It is narrowly separated from Bhutan and Nepal by the Siliguri Corridor; and from China by the Indian state of Sikkim in the north. Dhaka, the capital and largest city, is the nation's political, financial and cultural centre. Chittagong, the second-largest city, is the busiest port on the Bay of Bengal. The official language is Bengali. Bangladesh forms the sovereign part of the historic and ethnolinguistic region of Bengal, which was divided during the Partition of India in 1947. The country has a Bengali Muslim majority. Ancient Bengal was known as Gangaridai and was a bastion of pre-Islamic kingdoms. Muslim conquests after 1204 heralded the sultanate and Mughal periods, during which an independent Bengal Sultanate and a wealthy Mughal Bengal transformed the region into an important centre of regional affairs, trade, and diplomacy. After 1757, Bengal's administrative jurisdiction reached its greatest extent under the Bengal Presidency of the British Empire. The creation of Eastern Bengal and Assam in 1905 set a precedent for the emergence of Bangladesh. In 1940, the first Prime Minister of Bengal A. K. Fazlul Huq supported the Lahore Resolution. Before the partition of Bengal, a Bengali sovereign state was first proposed by premier H. S. Suhrawardy. A referendum and the announcement of the Radcliffe Line established the present-day territorial boundary. In 1947, East Bengal became the most populous province in the Dominion of Pakistan. It was renamed as East Pakistan, with Dhaka becoming the country's legislative capital. The Bengali Language Movement in 1952; the East Bengali legislative election, 1954; the 1958 Pakistani coup d'état; the six point movement of 1966; and the 1970 Pakistani general election resulted in the rise of Bengali nationalism and pro-democracy movements. The refusal of the Pakistani military junta to transfer power to the Awami League led by Sheikh Mujibur Rahman led to the Bangladesh Liberation War in 1971, in which the Mukti Bahini aided by India waged a successful armed revolution. The conflict saw the Bangladesh genocide and the massacre of pro-independence Bengali civilians, including intellectuals. The new state of Bangladesh became the first constitutionally secular state in South Asia in 1972. Islam was declared the state religion in 1988. In 2010, the Bangladesh Supreme Court reaffirmed secular principles in the constitution. A middle power in the Indo-Pacific, Bangladesh is home to the sixth-most spoken language in the world, the third-largest Muslim-majority population in the world, and the second-largest economy in South Asia. It maintains the third-largest military in the region and is the largest contributor of personnel to UN peacekeeping operations. Bangladesh is a unitary parliamentary republic based on the Westminster system. Bengalis make up 99% of the total population. The country consists of eight divisions, 64 districts and 495 subdistricts, as well as the world's largest mangrove forest. It hosts one of the largest refugee populations in the world due to the Rohingya genocide. Bangladesh faces many challenges, particularly corruption, political instability, overpopulation and effects of climate change. Bangladesh has been a leader within the Climate Vulnerable Forum. It hosts the headquarters of BIMSTEC. It is a founding member of SAARC, as well as a member of the Organisation of Islamic Cooperation and the Commonwealth of Nations. Etymology The etymology of Bangladesh ("Bengali country") can be traced to the early 20th century, when Bengali patriotic songs, such as Namo Namo Namo Bangladesh Momo by Kazi Nazrul Islam and Aaji Bangladesher Hridoy by Rabindranath Tagore, used the term. Starting in the 1950s, Bengali nationalists used the term in political rallies in East Pakistan. The term Bangla is a major name for both the Bengal region and the Bengali language. The origins of the term Bangla are unclear, with theories pointing to a Bronze Age proto-Dravidian tribe, and the Iron Age Vanga Kingdom. The earliest known usage of the term is the Nesari plate in 805 AD. The term Vangala Desa is found in 11th-century South Indian records. The term gained official status during the Sultanate of Bengal in the 14th century. Shamsuddin Ilyas Shah proclaimed himself as the first "Shah of Bangala" in 1342. The word Bangāl became the most common name for the region during the Islamic period. 16th-century historian Abu'l-Fazl ibn Mubarak mentions in his Ain-i-Akbari that the addition of the suffix "al" came from the fact that the ancient rajahs of the land raised mounds of earth in lowlands at the foot of the hills which were called "al". This is also mentioned in Ghulam Husain Salim's Riyaz-us-Salatin. The Indo-Aryan suffix Desh is derived from the Sanskrit word deśha, which means "land" or "country". Hence, the name Bangladesh means "Land of Bengal" or "Country of Bengal". History Ancient Bengal Stone Age tools have been found in different parts of Bangladesh. Remnants of Copper Age settlements date back 4,000 years. Ancient Bengal was settled by Austroasiatics, Tibeto-Burmans, Dravidians and Indo-Aryans in consecutive waves of migration. Archaeological evidence confirms that by the second millennium BCE, rice-cultivating communities inhabited the region. By the 11th century, people lived in systemically aligned housing, buried their dead, and manufactured copper ornaments and black and red pottery. The Ganges, Brahmaputra and Meghna rivers were natural arteries for communication and transportation, and estuaries on the Bay of Bengal permitted maritime trade. The early Iron Age saw the development of metal weaponry, coinage, agriculture and irrigation. Major urban settlements formed during the late Iron Age, in the mid-first millennium BCE, when the Northern Black Polished Ware culture developed. In 1879, Alexander Cunningham identified Mahasthangarh as the capital of the Pundra Kingdom mentioned in the Rigveda. The oldest inscription in Bangladesh was found in Mahasthangarh and dates from the 3rd century BCE, written in the Brahmi script. Greek and Roman records of the ancient Gangaridai Kingdom, which (according to legend) deterred the invasion of Alexander the Great, are linked to the fort city in Wari-Bateshwar. The site is also identified with the prosperous trading centre of Souanagoura listed on Ptolemy's world map. Roman geographers noted a large seaport in southeastern Bengal, corresponding to the present-day Chittagong region. Ancient Buddhist and Hindu states which ruled Bangladesh included the Vanga, Samatata and Pundra kingdoms, the Mauryan and Gupta Empires, the Varman dynasty, Shashanka's kingdom, the Khadga and Candra dynasties, the Pala Empire, the Sena dynasty, the Harikela kingdom and the Deva dynasty. These states had well-developed currencies, banking, shipping, architecture, and art, and the ancient universities of Bikrampur and Mainamati hosted scholars from other parts of Asia. Gopala I was the first ever elected ruler of the region in 750 AD; he went on to form the Pala dynasty that ruled until 1161 AD, during which time Bengal prospered. Xuanzang of China was a noted scholar who resided at the Somapura Mahavihara (the largest monastery in ancient India), and Atisa travelled from Bengal to Tibet to preach Buddhism. The earliest form of the Bengali language emerged during the eighth century. Seafarers in the Bay of Bengal sailed and traded with Southeast Asia and exported Buddhist and Hindu cultures to the region since the early Christian era. Islamic Bengal The early history of Islam in Bengal is divided into two phases: the period of maritime trade with Arabia and Persia between the 8th and 12th centuries, and centuries of Muslim dynastic rule after the Islamic conquest of Bengal. The writings of Al-Idrisi, Ibn Hawqal, Al-Masudi, Ibn Khordadbeh and Sulaiman record the maritime links between Arabia, Persia and Bengal. Muslim trade with Bengal flourished after the fall of the Sasanian Empire and the Arab takeover of Persian trade routes. Much of this trade occurred with southeastern Bengal in areas east of the Meghna River. There is speculation regarding the presence of a Muslim community in Bangladesh as early as 690 CE; this is based on the discovery of one of South Asia's oldest mosques in northern Bangladesh. Bengal was possibly used as a transit route to China by the earliest Muslims. Abbasid coins have been discovered in the archaeological ruins of Paharpur and Mainamati. Sultanate period The Muslim conquest of Bengal began with the 1204 Ghurid expeditions led by Muhammad bin Bakhtiyar Khalji, who overran the Sena capital in Gauda and led the first Muslim army into Tibet. Bengal was ruled by the Sultans of the Delhi Sultanate for a century under the Mamluk, Balban, and Tughluq dynasties. In the 14th century, three city-states emerged in Bengal, including Sonargaon led by Fakhruddin Mubarak Shah, Satgaon led by Shamsuddin Ilyas Shah and Lakhnauti led by Alauddin Ali Shah. These city-states were led by former governors who declared independence from Delhi. In 1352, Shamsuddin Ilyas Shah united the three city-states into a single, unitary and independent Bengal Sultanate. The new Sultan of Bengal forced the Sultan of Delhi to retreat during an invasion. The army of Ilyas Shah reached as far as Varanasi in the northwest, Kathmandu in the north, Kamarupa in the east, and Orissa in the south. During the reign of Sikandar Shah, Delhi recognised Bengal's independence. The Bengal Sultanate established a network of mint towns that acted as provincial capitals where the Sultan's currency was minted. As Bengal became the easternmost frontier of the Islamic world, Bengali crystallized as an official court language, giving rise to various prominent writers. The sultanate was evolving as a commercialized and monetized economy and as a melting pot of Muslim political, mercantile and military elites. The two most prominent dynasties of the Bengal Sultanate were the Ilyas Shahi and Hussain Shahi dynasties. The reign of Sultan Ghiyasuddin Azam Shah saw the opening of diplomatic relations with Ming China. The reign of the Sultan Jalaluddin Muhammad Shah saw the development of Bengali architecture. During the early 15th century, Bengal aided the Restoration of Min Saw Mon in Arakan, which led to the latter becoming a tributary state of Bengal. During the reign of Sultan Alauddin Hussain Shah, Bengali forces penetrated deep into the Brahmaputra Valley—and being led by Shah Ismail Ghazi, conquered Assam, Jajnagar in Orissa, the Jaunpur Sultanate, Pratapgarh Kingdom and the island of Chandradwip. By 1500, Gaur became the fifth-most populous city in the world with a population of 200,000. Maritime trade linked Bengal with China, Malacca, Sumatra, Brunei, Portuguese India, East Africa, Arabia, Persia, Mesopotamia, Yemen and the Maldives. The Sultans permitted the opening of the Portuguese settlement in Chittagong. The disintegration of the Bengal Sultanate began with the intervention of the Suri Empire. Babur began invading Bengal after creating the Mughal Empire. The Bengal Sultanate collapsed with the overthrow of the Karrani dynasty during the reign of Akbar. However, the Bhati region of eastern Bengal continued to be ruled by aristocrats of the former Bengal Sultanate led by Isa Khan. They formed an independent federation called the Twelve Bhuiyans, with their capital in Sonargaon. The Bhuiyans ultimately succumbed to the Mughals after Musa Khan was defeated. Mughal period The Mughal Empire controlled Bengal by the 17th century. Musa Khan of Bengal, the last independent ruler of Sonargaon after resisting Mughal conquest for several years on 10 July 1610 was defeated and dethroned by Islam Khan Chishti, the army general of Mughal Emperor Jahangir. Islam Khan Chisty became the first Mughal Subahdar of Bengal. After his defeat Musa Khan became loyal to the Mughal Empire. He actively participated in the conquest of Tripura and the suppression of revolt in Kamrup. The Mughals established Dhaka as a fort city and commercial metropolis. It was the capital of Bengal Subah for 75 years. n 1666, the Mughals expelled the Arakanese from the port of Chittagong. Mughal Bengal attracted foreign traders for its muslin and silk goods, and the Armenians were a notable merchant community. A Portuguese settlement in Chittagong flourished in the southeast, and a Dutch settlement in Rajshahi existed in the north. Bengal accounted for 40% of overall Dutch imports from Asia, including more than 50% of textiles and around 80% of silks. The Bengal Subah, described as the Paradise of the Nations, was the empire's wealthiest province, and a major global exporter, a notable centre of worldwide industries such as muslin, cotton textiles, silk, and shipbuilding. Its citizens enjoyed one of the world's best living standards. During the 18th century, the Nawabs of Bengal became the region's de facto rulers, with a realm encompassing much of eastern South Asia. The Nawabs forged alliances with European colonial companies, making the region relatively prosperous early in the century. Bengal accounted for 50% of the gross domestic product of the empire. The Bengali economy relied on textile manufacturing, shipbuilding, saltpetre production, craftsmanship, and agricultural produce. Bengal was a major hub for international trade, renowned for its silk and cotton textiles worldwide. Bengal was also famed as a shipbuilding hub. Eastern Bengal was a thriving melting pot with strong trade and cultural networks. It was a relatively prosperous part of the subcontinent and the centre of the Muslim population in the eastern subcontinent. The Bengali Muslim population was a product of conversion and religious evolution, and their pre-Islamic beliefs included elements of Buddhism and Hinduism. The construction of mosques, Islamic academies (madrasas), and Sufi monasteries (khanqahs) facilitated conversion, and Islamic cosmology played a significant role in developing Bengali Muslim society. Scholars have theorised that Bengalis were attracted to Islam by its egalitarian social order, which contrasted with the Hindu caste system. By the 15th century, Muslim poets were widely writing in the Bengali language. Syncretic cults, such as the Baul movement, emerged on the fringes of Bengali Muslim society. The Persianate culture was significant in Bengal, where cities like Sonargaon became the easternmost centres of Persian influence. In 1756, nawab Siraj ud-Daulah sought to rein in the rising power of the British East India Company by revoking their free trade rights and demanding the dismantling of their fortification in Calcutta. A military conflict culminated in the Battle of Plassey on 23 June 1757. Robert Clive exploited rivalries within the nawab's family, bribing Mir Jafar, the nawab's uncle and commander in chief, to ensure Siraj-ud-Daula's defeat. Clive rewarded Mir Jafar by making him nawab in place of Siraj-ud-Daula, but henceforth the position was a figurehead appointed and controlled by the company. Historians often describe the battle as "the beginning of British colonial rule in South Asia". The Company replaced Mir Jafar with his son-in-law, Mir Kasim, in 1760. Mir Kasim challenged British control by allying with Mughal emperor Shah Alam II and the Nawab of Awadh, Shuja ud-Daulah, but the company decisively defeated the three at the Battle of Buxar on 23 October 1764. The resulting treaty made the Mughal emperor a puppet of the British and gave the company the right to collect taxes (diwani) in Bengal, Bihar, and Orissa, giving them de facto control of the region. The Company used Bengal's tax revenue to conquer the rest of India. Colonial period Initial period The Bengal Sultanate permitted the Portuguese settlement in Chittagong to be established in 1528. It became the first European colonial enclave in Bengal. The Bengal Sultanate lost control of Chittagong in 1531 after Arakan declared independence and the established Kingdom of Mrauk U. Portuguese ships from Goa and Malacca began frequenting the port city in the 16th century. The cartaz system was introduced and required all ships in the area to purchase naval trading licenses from the Portuguese. Slave trade and piracy flourished. The nearby island of Sandwip was conquered in 1602. In 1615, the Portuguese Navy defeated a joint Dutch East India Company and Arakanese fleet near the coast of Chittagong. The Bengal Sultan after 1534 allowed the Portuguese to create several settlements at Chitagoong, Satgaon, Hughli, Bandel, and Dhaka. In 1535, the Portuguese allied with the Bengal sultan and held the Teliagarhi pass from Patna helping to avoid the invasion by the Mughals. By then several of the products came from Patna and the Portuguese send in traders, establishing a factory there in 1580. The region accounted for 40% of Dutch imports outside Europe.In 1666, the Mughal government of Bengal led by viceroy Shaista Khan moved to retake Chittagong from Portuguese and Arakanese control. The Anglo-Mughal War was witnessed in 1686. Company rule After the 1757 Battle of Plassey, Bengal was the first region of the Indian subcontinent conquered by the British East India Company. The company formed the Presidency of Fort William, which administered the region until 1858. A notable aspect of Company rule was the Permanent Settlement, which established the feudal zamindari system; in addition, Company policies led to the deindustrialisation of Bengal's textile industry. The capital amassed by the East India Company in Bengal was invested in the emerging Industrial Revolution in Great Britain. Economic mismanagement, alongside drought and a smallpox epidemic, directly led to the Great Bengal famine of 1770, which is estimated to have caused the deaths of between 1 million and 10 million people. Several rebellions broke out during the early 19th century, as Company rule had displaced the Muslim ruling class from power. A conservative Islamic cleric, Haji Shariatullah, sought to overthrow the British by propagating Islamic revivalism. Several towns in Bangladesh participated in the Indian Rebellion of 1857. British Raj The challenge posed to company rule by the failed Indian Mutiny led to the creation of the British Indian Empire as a crown colony. The British established several schools, colleges, and a university in Bangladesh. Syed Ahmed Khan and Ram Mohan Roy promoted modern and liberal education in the subcontinent, inspiring the Aligarh movement and the Bengal Renaissance. During the late 19th century, novelists, social reformers, and feminists emerged from Muslim Bengali society. Electricity and municipal water systems were introduced in the 1890s; cinemas opened in many towns during the early 20th century. East Bengal's plantation economy was important to the British Empire, particularly its jute and tea. The British established tax-free river ports, such as the Port of Narayanganj, and large seaports like the Port of Chittagong. Bengal had the highest gross domestic product in British India. Bengal was one of the first regions in Asia to have a railway, which began operating in 1862. The main railway companies in the region were the Eastern Bengal Railway and Assam Bengal Railway. Railways competed with waterborne transport to become one of the main means of transport. Supported by the Muslim aristocracy, the British government created the province of Eastern Bengal and Assam in 1905; the new province received increased investment in education, transport, and industry. However, the first partition of Bengal created an uproar in Calcutta and the Indian National Congress. In response to growing Hindu nationalism, the All India Muslim League was formed in Dhaka in 1906. The British government reorganised the provinces in 1912, reuniting East and West Bengal and making Assam a second province. The Raj was slow to allow self-rule in the colonial subcontinent. It established the Bengal Legislative Council in 1862, and the council's native Bengali representation increased during the early 20th century. The Bengal Provincial Muslim League was formed in 1913 to advocate civil rights for Bengali Muslims. During the 1920s, the league was divided into factions supporting the Khilafat movement and favouring cooperation with the British to achieve self-rule. Segments of the Bengali elite supported Mustafa Kemal Atatürk's secularist forces. In 1929, the All Bengal Tenants Association was formed in the Bengal Legislative Council to counter the influence of the Hindu landed gentry, and the Indian Independence and Pakistan Movements strengthened during the early 20th century. After the Morley-Minto Reforms and the diarchy era in the legislatures of British India, the British government promised limited provincial autonomy in 1935. The Bengal Legislative Assembly, British India's largest legislature, was established in 1937. Although it won most seats in 1937, the Bengal Congress boycotted the legislature. A. K. Fazlul Huq of the Krishak Praja Party was elected as the first Prime Minister of Bengal. In 1940 Huq supported the Lahore Resolution, which envisaged independent states in the subcontinent's northwestern and eastern Muslim-majority regions. Huq was succeeded by Khawaja Nazimuddin, who grappled with the effects of the Burma Campaign, the Bengal famine of 1943, which killed up to 3 million people, and the Quit India movement. In 1946, the Bengal Provincial Muslim League won the provincial election with the largest Muslim League mandate in British India. H. S. Suhrawardy, who made a final futile effort for a United Bengal in 1946, was the last premier of Bengal. Partition of Bengal (1947) On 3 June 1947, the Mountbatten Plan outlined the partition of British India. On 6 July, the Sylhet region of Assam voted in a referendum to join East Bengal. Cyril Radcliffe was tasked with drawing the borders of Pakistan and India, and the Radcliffe Line established the boundaries of present-day Bangladesh. The Radcliffe Line awarded two-thirds of Bengal as the eastern wing of Pakistan, but the medieval and early modern Bengali capitals of Gaur, Pandua and Murshidabad fell on the Indian side close to the border with Pakistan. Union with Pakistan The Dominion of Pakistan was created on 14 August 1947. East Bengal, with Dhaka as its capital, was the most populous province of the 1947 Pakistani federation (led by Muhammad Ali Jinnah, who promised freedom of religion and secular democracy in the new state). Khawaja Nazimuddin was East Bengal's first chief minister with Frederick Chalmers Bourne its governor. The All Pakistan Awami Muslim League was formed in 1949. In 1950, the East Bengal Legislative Assembly enacted land reform, abolishing the Permanent Settlement and the zamindari system. The 1952 Bengali Language Movement was the first sign of friction between the country's geographically separated wings. The Awami Muslim League was renamed the more secular Awami League in 1953. The first constituent assembly was dissolved in 1954. The United Front coalition swept aside the Muslim League in a landslide victory in the 1954 East Bengali legislative election. The following year, East Bengal renamed East Pakistan as part of the One Unit programme, and the province became a vital part of the Southeast Asia Treaty Organization. Pakistan adopted a new constitution in 1956. The Pakistan Army imposed military rule in 1958, and Ayub Khan was the country's strongman for 11 years. Political repression increased after the coup. Khan introduced a new constitution in 1962, replacing Pakistan's parliamentary system with a presidential and gubernatorial system (based on electoral college selection) known as Basic Democracy. In 1962, Dhaka became the seat of the National Assembly of Pakistan, a move seen as appeasing increased Bengali nationalism. The Pakistani government built the controversial Kaptai Dam, displacing the Chakma people from their indigenous homeland in the Chittagong Hill Tracts. The Indo-Pakistani War of 1965 blocked cross-border transport links with neighbouring India in what is described as a second partition. In 1966, Awami League leader Sheikh Mujibur Rahman announced a six-point movement for a federal parliamentary democracy. According to senior World Bank officials, the Pakistani government practised extensively economic discrimination against East Pakistan. Despite generating 70 per cent of Pakistan's export revenue with jute and tea, East Pakistan received much less government spending than West Pakistan. Economists in East Pakistan, including Rehman Sobhan and Nurul Islam among others, demanded a separate foreign exchange account for the eastern wing. The economists paraphrased Pakistan's Two-Nation Theory ideology against India, by pointing to the existence of two different economies with Pakistan itself, dubbed the Two-Economies Theory. The central government also refused to release foreign aid allocated for East Pakistan. The populist leader Sheikh Mujibur Rahman was arrested for treason in the Agartala Conspiracy Case and was released during the 1969 uprising in East Pakistan which resulted in Ayub Khan's resignation. General Yahya Khan assumed power, reintroducing martial law. Ethnic and linguistic discrimination was common in Pakistan's civil and military services, in which Bengalis were under-represented. Cultural discrimination also prevailed, making East Pakistan forge a distinct political identity. Authorities banned Bengali literature and music in state media. A cyclone devastated the coast of East Pakistan in 1970, killing an estimated 500,000 people, and the central government was criticised for its poor response. After the December 1970 elections, the Bengali-nationalist Awami League won 167 of 169 East Pakistani seats in the National Assembly. The League claimed the right to form a government and develop a new constitution but was strongly opposed by the Pakistani military and the Pakistan Peoples Party (led by Zulfikar Ali Bhutto). War of Independence In early 1971, negotiations began on the transfer of power. The Awami League wanted to develop a constitution based on its Six Points agenda; this was opposed by the Pakistani military, the Pakistan Peoples Party and the Muslim League factions. Talks eventually broke down as the junta led by Yahya Khan prepared for a military operation in East Pakistan. The Bengali population was angered when the newly elected National Assembly was not convened under pressure from the junta and West Pakistani politicians. Despite enjoying an absolute majority in the newly elected parliament, Prime Minister-elect Sheikh Mujibur Rahman was prevented from taking the oath. Zulfikar Ali Bhutto threatened to break the legs of West Pakistani MPs if they flew to Dhaka for the first session of parliament. Civil disobedience erupted across East Pakistan, with loud calls for independence. Mujib addressed a pro-independence rally of nearly 2 million people on 7 March 1971, where he said, "This time the struggle is for our liberation. This time the struggle is for our independence". The flag of Bangladesh was raised for the first time on 23 March, Pakistan's Republic Day. Around midnight on 26 March 1971, military operations under the code name of Operation Searchlight began. The first targets were the student dormitories of Dhaka University, the police barracks in Dhaka's Rajarbagh locality, and Hindu neighbourhoods in Old Dhaka. The Pakistan Army arrested Sheikh Mujibur Rahman and flew him to a jail in West Pakistan. The army burnt down the Ittefaq newspaper's office. Before his arrest, Mujib proclaimed the independence of Bangladesh. Pakistani forces launched a widespread campaign of killings, torture, rape, arson and destruction across East Pakistan, targeting segments of the population perceived to be pro-Awami League and pro-independence. The Hindu minority was distinctly targeted because of Pakistan's hostility with neighbouring Hindu-majority India. During the Bangladesh Liberation War, the Mukti Bahini emerged as the Bengali resistance force. A highly successful guerrilla war was fought against Pakistan. Bengalis continued to defect from Pakistan's diplomatic service, military, police, and bureaucracy. In April, they helped Awami League leaders to set up the Provisional Government of Bangladesh, which operated in exile from Calcutta with the support of the Indian government until December 1971. The Bangladesh Armed Forces was formally established in November 1971, when Bengali forces secured control of much of the countryside. The Mukti Bahini forced the railway network to shut down to stop Pakistani troop movements. Some of the notable operations of the Mukti Bahini included Operation Jackpot and Operation Barisal. India intervened in the war on 3 December 1971, after Pakistan's failed pre-emptive air strikes on India's northwestern flank. With a joint ground advance by Bangladeshi and Indian forces, coupled with air strikes by both India and the small Bangladeshi air contingent, the capital Dhaka was liberated from Pakistani occupation in mid-December. During the last phase of the war, both the Soviet Union and the United States dispatched naval forces to the Bay of Bengal in a Cold War standoff. The nine-month-long war ended with the surrender of the Pakistan Eastern Command to the Bangladesh-India Allied Forces on 16 December 1971. Under international pressure, Pakistan released Mujib from imprisonment on 8 January 1972 and he was flown to a million-strong homecoming in Dhaka. Remaining Indian troops were withdrawn by 12 March 1972. By August 1972, the new state was recognised by 86 countries. Pakistan recognised Bangladesh in 1974 after pressure from most of the Muslim countries. The government of Bangladesh records the official death toll of the war at 3 million, including victims of atrocities and those who died from starvation. Minimum estimates for the number of those killed range between 300,000 and 500,000. An estimated 10 million refugees fled to neighboring India and 30 million were internally displaced. The war was one of the first to record the use of rape as a weapon of war, with an estimated 200,000 women being subjected to sexual abuse by the Pakistani army. The war saw the systematic targeting of Bengali elites, particularly intellectuals. The Jamaat-e-Islami formed paramilitary militias, which aided Pakistani troops and guided them to their intended targets. While Bengali Muslims bore the brunt of atrocities because of racial tensions with the largely Punjabi Muslim West Pakistani forces, the minority Bengali Hindu community was singled out for attacks by the Pakistani armed forces, a legacy which has led Hindu nationalist groups to claim that the war was a Hindu genocide. Archer Blood, the US Consul General in East Pakistan at the time of the war, described the situation as "selective genocide". In 1974 and 2002, Pakistan formally expressed "regret" for what happened. In 2015, Pakistan denied any atrocities took place. In 2022, a bipartisan resolution was introduced in the US Congress to "Recognize the Bangladesh Genocide of 1971". The International Association of Genocide Scholars regards the atrocities as a genocide. Modern Bangladesh First parliamentary era The new government of Bangladesh transformed East Pakistan's state apparatus into an independent Bangladeshi state. The Awami League successfully reorganised the bureaucracy, framed a written constitution, and rehabilitated war victims. In January 1972, Mujib introduced a parliamentary republic through a presidential decree. On 12 January 1972 Mujib took oath and assumed office as Prime Minister of Bangladesh. The emerging state structure was heavily influenced by the British Westminster model. The Constitution Drafting Committee led by Kamal Hossain established a bill of rights influenced by the Universal Declaration of Human Rights. The constituent assembly adopted the constitution of Bangladesh on 4 November 1972, establishing a secular, multiparty parliamentary democracy. Bangladesh joined the Commonwealth of Nations, the UN, the OIC, and the Non-Aligned Movement. In his maiden speech to the UNGA, Mujib stated that "the Bengali has struggled for many centuries for the right to live a free and honourable life as independent citizens of an independent country. They expected to live in peace and harmony with all the nations in the world". He strengthened relations with India by signing a 25-year friendship treaty, a border demarcation agreement, and protocols on cross-border trade. The land boundary treaty was aimed at resolving border disputes inherited from East Pakistan and swapping the Indo-Bangladesh enclaves. The land boundary agreement was challenged in court, which ruled that the government needed the prior approval of parliament to implement the land boundary treaty. Mujib was a vocal supporter of Palestinian rights despite Israel being one of the first countries to recognize Bangladesh's independence. In what became Bangladesh's first dispatch of military aid overseas, Mujib sent an army medical unit to Egypt during the 1973 Arab-Israeli War. In economic policy, the first five years of Bangladesh was the only socialist period in its history. Mujib nationalized 580 industrial plants, as well as banks and insurance companies. In 1974, the government invited international oil companies to explore the Bay of Bengal for oil and natural gas. Petrobangla was established as the national oil and gas corporation. The Mujib government faced huge economic problems exasperated by the resettlement of millions of people displaced in 1971, a breakdown in the food supply chain, poor health services and a lack of other necessities. The effects of the 1970 cyclone were still being felt, and the economy needed reconstruction after the war. The Bangladesh famine of 1974 damaged Mujib's popularity. Mujib presided over a regime that was built around his personality cult. Sycophants and loyalists developed an ideology called Mujibism. Presidential era (1975–1991) In January 1975, Sheikh Mujibur Rahman introduced one-party socialist rule under BAKSAL. Rahman banned all newspapers except four state-owned publications and amended the constitution to increase his power. He was assassinated during a coup on 15 August 1975, and the presidency passed to the usurper Khondaker Mostaq Ahmad for four months. Ahmad is widely regarded as a traitor by Bangladeshis. Tajuddin Ahmad, the nation's first prime minister, and four other independence leaders were assassinated on 4 November 1975. Chief Justice Abu Sadat Mohammad Sayem was installed as president by the military on 6 November 1975. Bangladesh was governed by a military junta led by the Chief Martial Law Administrator for three years. In 1977, the army chief Ziaur Rahman became president. Rahman reinstated multiparty politics, privatised industries and newspapers, re-opened the Dhaka Stock Exchange, established BEPZA and held the country's second general election in 1979. In 1978, 200,000 Arakanese Muslim refugees crossed the Naf River into Bangladesh due to a Burmese military crackdown. The refugees were later repatriated. A semi-presidential system evolved, with the Bangladesh Nationalist Party (BNP) governing until 1982. Rahman was assassinated in 1981 and was succeeded by vice-president Abdus Sattar. After a year in office, Sattar was overthrown in the 1982 Bangladesh coup d'état. Chief Justice A. F. M. Ahsanuddin Chowdhury was installed as president, but army chief Hussain Muhammad Ershad became the country's de facto leader and assumed the presidency in 1983. Ershad lifted martial law in 1986. He governed with four successive prime ministers (Ataur Rahman Khan, Mizanur Rahman Chowdhury, Moudud Ahmed and Kazi Zafar Ahmed) and a parliament dominated by his Jatiyo Party. Ershad pursued administrative decentralisation, dividing the country into 64 districts, and pushed Parliament to make Islam the state religion in 1988. Bangladesh dispatched its first contingent of UN peacekeepers in 1988. In 1990, Bangladesh joined the US-led coalition to liberate Kuwait during the Gulf War. A mass uprising forced Ershad to resign, and Chief Justice Shahabuddin Ahmed led the country's first caretaker government as part of the transition to parliamentary rule. Parliamentary era (1991–present) After the 1991 general election, the twelfth amendment to the constitution restored the parliamentary republic, and Begum Khaleda Zia became Bangladesh's first female prime minister. Zia, a former first lady, led a BNP government from 1990 to 1996. In 1991, her finance minister, Saifur Rahman, began a major programme to liberalise the Bangladeshi economy. In addition to setting up the Chittagong Stock Exchange; banking, pharmaceuticals, aviation, ceramics, steel, telecoms, and tertiary education were opened up for investments, resulting in increased market competition. In 1992, an estimated 250,000 refugees from Burma took shelter in Bangladesh due to the suppression of the Burmese pro-democracy movement; most of these refugees returned to Burma by 1993. In 1994, Bangladesh provided the largest non-US contingent in Operation Uphold Democracy, a military intervention in Haiti. In 1996, a year of political upheaval saw a boycotted February election, an attempted military coup, and mediation efforts producing a caretaker government to oversee elections. For three months, Muhammad Habibur Rahman served as the interim leader of the country. The Awami League returned to power in the June election after 21 years. One of the first initiatives of Prime Minister Sheikh Hasina was to repeal the deeply controversial Indemnity Ordinance, which protected her father's killers from prosecution. Hasina also signed the Chittagong Hill Tracts Peace Accord, which ended an insurgency in the southeastern hill districts. She reached an agreement with India for sharing the water of the Ganges. The economic reform momentum lost steam due to political instability, including frequent hartals and strikes by the opposition. In 2001, the BNP returned to power on the back of promises to improve the economy. The second Zia administration saw higher economic growth, but security and political problems gripped the country between 2004 and 2006. A radical Islamist militant group, the JMB, carried out a series of terror attacks. At the end of the BNP's term in 2006, there was widespread political unrest. The Bangladeshi military urged President Iajuddin Ahmed to impose a state of emergency and a caretaker government, led by Fakhruddin Ahmed, was installed from January 2007 to December 2008 to implement reforms to the electoral system, judiciary, and bureaucracy. The JMB leaders were arrested and later executed in March 2007. After achieving a landslide victory in the 2008 Bangladeshi general election the Awami League Government returned to power taking oath on 6 January 2009, with Sheikh Hasina once again becoming the Prime Minister and brought political stability and economic growth to the nation. In 2010, the Supreme Court reduced the scope for military interventions through legal loopholes and reaffirmed secular principles in the constitution. The Awami League set up a war crimes tribunal to prosecute surviving Bengali Islamist collaborators of the 1971 atrocities. Human rights abuses increased under the Hasina administration, particularly enforced disappearances by the Rapid Action Battalion. The 2014 election was boycotted by the BNP-Jamaat alliance. The BNP and Jamaat have often engaged in violent protests to overthrow the government. In 2017, Bangladesh experienced the largest influx of Arakanese refugees in its history. An estimated 700,000 Rohingya refugees took shelter in Cox's Bazar after a campaign of ethnic cleansing in Rakhine State, Myanmar. The national poverty rate went down from 80% in 1971 to 44.2% in 1991 to 12.9% in 2021. Bangladeshi economist Muhammad Yunus and the Grameen Bank, which Yunus founded, were awarded the Nobel Peace Prize for pioneering microfinance and their efforts to eradicate poverty. Bangladesh has emerged as the second-largest economy in South Asia, surpassing the per capita income levels of both India and Pakistan. Since 2009, Bangladesh has launched a series of infrastructure megaprojects. On 25 June 2022, the Padma Bridge opened and connected southwestern Bangladesh with the rest of the country, while the Dhaka Metro was opened in 2023. As part of the green transition, Bangladesh's industrial sector emerged as a leader in building green factories, with the country having the largest number of certified green factories in the world in 2023. Geography Bangladesh is in South Asia on the Bay of Bengal. It is surrounded almost entirely by neighbouring India, and shares a small border with Myanmar to its southeast, though it lies very close to Nepal, Bhutan, and China. The country is divided into three regions. Most of the country is dominated by the fertile Ganges Delta, the largest river delta in the world. The northwest and central parts of the country are formed by the Madhupur and the Barind plateaus. The northeast and southeast are home to evergreen hill ranges. The Ganges delta is formed by the confluence of the Ganges (local name Padma or Pôdda), Brahmaputra (Jamuna or Jomuna), and Meghna rivers and their tributaries. The Ganges unites with the Jamuna (main channel of the Brahmaputra) and later join the Meghna, finally flowing into the Bay of Bengal. Bangladesh is called the "Land of Rivers"; as it is home to over 57 trans-boundary rivers, the most of any nation-state. Water issues are hence politically complicated inasmuch as the country is a lower riparian state to India. Bangladesh is predominantly rich fertile flat land. Most of it is less than above sea level, and it is estimated that about 10% of its land would be flooded if the sea level were to rise by . 17% of the country is covered by forests and 12% is covered by hill systems. The country's haor wetlands are of significance to global environmental science. The highest point in Bangladesh is the Saka Haphong, located near the border with Myanmar, with an elevation of . Previously, either Keokradong or Tazing Dong were considered the highest. Administrative divisions Bangladesh is divided into eight administrative divisions, each named after their respective divisional headquarters: Barisal (officially Barishal), Chittagong (officially Chattogram), Dhaka, Khulna, Mymensingh, Rajshahi, Rangpur, and Sylhet. Divisions are subdivided into districts (zila). There are 64 districts in Bangladesh, each further subdivided into upazila (subdistricts) or thana. The area within each police station, except for those in metropolitan areas, is divided into several unions, with each union consisting of multiple villages. In the metropolitan areas, police stations are divided into wards, further divided into mahallas. There are no elected officials at the divisional or district levels, and the administration is composed only of government officials. Direct elections are held in each union (or ward) for a chairperson and a number of members. In 1997, a parliamentary act was passed to reserve three seats (out of 12) in every union for female candidates. Climate Straddling the Tropic of Cancer, Bangladesh's climate is tropical, with a mild winter from October to March and a hot, humid summer from March to June. The country has never recorded an air temperature below , with a record low of in the northwest city of Dinajpur on 3 February 1905. A warm and humid monsoon season lasts from June to October and supplies most of the country's rainfall. Natural calamities, such as floods, tropical cyclones, tornadoes, and tidal bores occur almost every year, combined with the effects of deforestation, soil degradation and erosion. The cyclones of 1970 and 1991 were particularly devastating, the latter killing approximately 140,000 people. In September 1998, Bangladesh saw the most severe flooding in modern history, after which two-thirds of the country went underwater, along with a death toll of 1,000. As a result of various international and national level initiatives in disaster risk reduction, the human toll and economic damage from floods and cyclones have come down over the years. The 2007 South Asian floods ravaged areas across the country, leaving five million people displaced, had a death toll around 500. Bangladesh is recognised to be one of the countries most vulnerable to climate change. Over the course of a century, 508 cyclones have affected the Bay of Bengal region, 17 percent of which are believed to have made landfall in Bangladesh. Natural hazards that come from increased rainfall, rising sea levels, and tropical cyclones are expected to increase as the climate changes, each seriously affecting agriculture, water and food security, human health, and shelter. It is estimated that by 2050, a three-foot rise in sea levels will inundate some 20 percent of the land and displace more than 30 million people. To address the sea level rise threat in Bangladesh, the Bangladesh Delta Plan 2100 has been launched. Biodiversity Bangladesh is located in the Indomalayan realm, and lies within four terrestrial ecoregions: Lower Gangetic Plains moist deciduous forests, Mizoram–Manipur–Kachin rain forests, Sundarbans freshwater swamp forests, and Sundarbans mangroves. Its ecology includes a long sea coastline, numerous rivers and tributaries, lakes, wetlands, evergreen forests, semi evergreen forests, hill forests, moist deciduous forests, freshwater swamp forests and flat land with tall grass. The Bangladesh Plain is famous for its fertile alluvial soil which supports extensive cultivation. The country is dominated by lush vegetation, with villages often buried in groves of mango, jackfruit, bamboo, betel nut, coconut, and date palm. The country has up to 6000 species of plant life, including 5000 flowering plants. Water bodies and wetland systems provide a habitat for many aquatic plants. Water lilies and lotuses grow vividly during the monsoon season. The country has 50 wildlife sanctuaries. Bangladesh is home to much of the Sundarbans, the world's largest mangrove forest, covering an area of in the southwest littoral region. It is divided into three protected sanctuaries–the South, East, and West zones. The forest is a UNESCO World Heritage Site. The northeastern Sylhet region is home to haor wetlands, a unique ecosystem. It also includes tropical and subtropical coniferous forests, a freshwater swamp forest, and mixed deciduous forests. The southeastern Chittagong region covers evergreen and semi-evergreen hilly jungles. Central Bangladesh includes the plainland Sal forest running along with the districts of Gazipur, Tangail, and Mymensingh. St. Martin's Island is the only coral reef in the country. Bangladesh has an abundance of wildlife in its forests, marshes, woodlands, and hills. The vast majority of animals dwell within a habitat of . The Bengal tiger, clouded leopard, saltwater crocodile, black panther and fishing cat are among the chief predators in the Sundarbans. Northern and eastern Bangladesh is home to the Asian elephant, hoolock gibbon, Asian black bear and oriental pied hornbill. The Chital deer are widely seen in southwestern woodlands. Other animals include the black giant squirrel, capped langur, Bengal fox, sambar deer, jungle cat, king cobra, wild boar, mongooses, pangolins, pythons and water monitors. Bangladesh has one of the largest populations of Irrawaddy and Ganges dolphins. The country has numerous species of amphibians (53), reptiles (139), marine reptiles (19) and marine mammals (5). It also has 628 species of birds. Several animals became extinct in Bangladesh during the last century, including the one-horned and two-horned rhinoceros and common peafowl. The human population is concentrated in urban areas, limiting deforestation to a certain extent. Rapid urban growth has threatened natural habitats. The country has widespread environmental issues, pollution of the Dhaleshwari River by the textile industry and shrimp cultivation in Chakaria Sundarbans have both been described by academics as ecocides. Although many areas are protected under law, some Bangladeshi wildlife is threatened by this growth. The Bangladesh Environment Conservation Act was enacted in 1995. The government has designated several regions as Ecologically Critical Areas, including wetlands, forests, and rivers. The Sundarbans tiger project and the Bangladesh Bear Project are among the key initiatives to strengthen conservation. It ratified the Rio Convention on Biological Diversity on 3 May 1994. , the country was set to revise its National Biodiversity Strategy and Action Plan. Politics and government Bangladesh is a de jure representative democracy under its constitution, with a Westminster-style parliamentary republic that has universal suffrage. The head of government is the Prime Minister, who forms a government every five years. The President invites the leader of the largest party in parliament to become Prime Minister. The Jatiya Sangshad (National Parliament) is the unicameral parliament. It has 350 Members of Parliament (MPs), including 300 MPs elected on the first past the post system and 50 MPs appointed to reserved seats for women's empowerment. Article 70 of the Constitution of Bangladesh forbids MPs from voting against their party. However, several laws proposed independently by MPs have been transformed into legislation, including the anti-torture law. The parliament is presided over by the Speaker of the Jatiya Sangsad, who is second in line to the president as per the constitution. The Government of Bangladesh is overseen by a cabinet headed by the Prime Minister of Bangladesh. The tenure of a parliamentary government is five years. The Bangladesh Civil Service assists the cabinet in running the government. Recruitment for the civil service is based on a public examination. In theory, the civil service should be a meritocracy. But a disputed quota system coupled with politicisation and preference for seniority have allegedly affected the civil service's meritocracy. The President of Bangladesh is the ceremonial head of state whose powers include signing bills passed by parliament into law. The President is the Supreme Commander of the Bangladesh Armed Forces and the chancellor of all universities. The Supreme Court of Bangladesh is the highest court of the land, followed by the High Court and Appellate Divisions. The head of the judiciary is the Chief Justice of Bangladesh, who sits on the Supreme Court. The courts have wide latitude in judicial review, and judicial precedent is supported by Article 111 of the constitution. The judiciary includes district and metropolitan courts divided into civil and criminal courts. Due to a shortage of judges, the judiciary has a large backlog. Military The Bangladesh Armed Forces have inherited the institutional framework of the British military and the British Indian Army. In 2022, the active personnel strength of the Bangladesh Army was around 250,000, excluding the Air Force and the Navy (24,000). In addition to traditional defence roles, the military has supported civil authorities in disaster relief and provided internal security during periods of political unrest. For many years, Bangladesh has been the world's largest contributor to UN peacekeeping forces. The military budget of Bangladesh accounts for 1.3% of GDP, amounting to US$4.3 billion in 2021. The Bangladesh Navy, one of the largest in the Bay of Bengal, includes a fleet of frigates, submarines, corvettes, and other vessels. The Bangladesh Air Force has a small fleet of multi-role combat aircraft. Most of Bangladesh's military equipment comes from China. In recent years, Bangladesh and India have increased joint military exercises, high-level visits of military leaders, counter-terrorism cooperation and intelligence sharing. Bangladesh is vital to ensuring stability and security in northeast India. Bangladesh's strategic importance in the eastern subcontinent hinges on its proximity to China, its frontier with Burma, the separation of mainland and northeast India, and its maritime territory in the Bay of Bengal. In 2002, Bangladesh and China signed a Defence Cooperation Agreement. The United States has pursued negotiations with Bangladesh on a Status of Forces Agreement, an Acquisition and Cross-Servicing Agreement and a General Security of Military Information Agreement. In 2019, Bangladesh ratified the UN Treaty on the Prohibition of Nuclear Weapons. Foreign relations Bangladesh is considered a middle power in global politics. It plays an important role in the geopolitical affairs of the Indo-Pacific, due to its strategic location between South and Southeast Asia. Bangladesh joined the Commonwealth of Nations in 1972 and the United Nations in 1974. It relies on multilateral diplomacy on issues like climate change, nuclear nonproliferation, trade policy and non-traditional security issues. Bangladesh pioneered the creation of SAARC, which has been the preeminent forum for regional diplomacy among the countries of the Indian subcontinent. It joined the Organisation of Islamic Cooperation in 1974, and is a founding member of the Developing 8 Countries. In recent years, Bangladesh has focused on promoting regional trade and transport links with support from the World Bank. Dhaka hosts the headquarters of BIMSTEC, an organisation that brings together countries dependent on the Bay of Bengal. Relations with neighbouring Myanmar have been severely strained since 2016–2017, after over 700,000 Rohingya refugees illegally entered Bangladesh. The parliament, government, and civil society of Bangladesh have been at the forefront of international criticism against Myanmar for military operations against the Rohingya, and have demanded their right of return to Arakan. Bangladesh shares an important bilateral and economic relationship with its largest neighbour India, which is often strained by water politics of the Ganges and the Teesta, and the border killings of Bangladeshi civilians. Post-independent Bangladesh has continued to have a problematic relationship with Pakistan, mainly due to its denial of the 1971 Bangladesh genocide. It maintains a warm relationship with China, which is its largest trading partner, and the largest arms supplier. Japan is Bangladesh's largest economic aid provider, and the two maintain a strategic and economic partnership. Political relations with Middle Eastern countries are robust. Bangladesh receives 59% of its remittances from the Middle East, despite poor working conditions affecting over 4 million Bangladeshi workers. Bangladesh plays a major role in global climate diplomacy as a leader of the Climate Vulnerable Forum. Civil society Since the colonial period, Bangladesh has had a prominent civil society. There are various special interest groups, including non-governmental organisations, human rights organisations, professional associations, chambers of commerce, employers' associations, and trade unions. The National Human Rights Commission of Bangladesh was set up in 2007. Notable human rights organisations and initiatives include the Centre for Law and Mediation, Odhikar, the Alliance for Bangladesh Worker Safety, the Bangladesh Environmental Lawyers Association, the Bangladesh Hindu Buddhist Christian Unity Council and the War Crimes Fact Finding Committee. The world's largest international NGO BRAC is based in Bangladesh. There have been concerns regarding the shrinking space for independent civil society in recent years. Human rights Torture is banned by the Constitution of Bangladesh, but is rampantly used by Bangladesh's security forces. Bangladesh joined the Convention against Torture in 1998 and it enacted its first anti-torture law, the Torture and Custodial Death (Prevention) Act, in 2013. The first conviction under this law was announced in 2020. Amnesty International Prisoners of Conscience from Bangladesh have included Saber Hossain Chowdhury and Shahidul Alam. The Digital Security Act of 2018 has greatly reduced freedom of expression in Bangladesh and has been used to target critics of the government. On International Human Rights Day in December 2021, the United States Department of Treasury announced sanctions on commanders of the Rapid Action Battalion for extrajudicial killings, torture, and other human rights abuses. Freedom House has criticised the ruling party for human rights abuses, the crackdown on the opposition, mass media, and civil society through politicized enforcement. Bangladesh is ranked "partly free" in Freedom House's Freedom in the World report, but its press freedom has deteriorated from "free" to "not free" in recent years due to increasing pressure from the authoritarian government. According to the British Economist Intelligence Unit, the country has a hybrid regime: the third of four rankings in its Democracy Index. Bangladesh was ranked 96th among 163 countries in the 2022 Global Peace Index. According to National Human Rights Commission, 70% of alleged human-rights violations are committed by law-enforcement agencies. LGBT rights are heavily suppressed: homosexuality is punishable by a maximum of life imprisonment. However, Bangladesh recognises the third gender and accords limited rights for transgender people. According to the 2016 Global Slavery Index, an estimated 1,531,300 people are enslaved in Bangladesh, or roughly 1% of the population. Corruption Like many developing countries, institutional corruption is an issue of concern for Bangladesh. Bangladesh was ranked 146th among 180 countries on Transparency International's 2018 Corruption Perceptions Index. Land administration was the sector with the most bribery in 2015, followed by education, police and water supply. The Anti Corruption Commission was formed in 2004, and it was active during the 2006–08 Bangladeshi political crisis, indicting many leading politicians, bureaucrats and businessmen for graft. Economy Bangladesh is the second largest economy in South Asia after India. The country has outpaced India and Pakistan in terms of per capita income. According to the World Bank, When the newly independent country of Bangladesh was born on December 16, 1971, it was the second poorest country in the world—making the country's transformation over the next 50 years one of the great development stories. Since then, poverty has been cut in half at record speed. Enrolment in primary school is now nearly universal. Hundreds of thousands of women have entered the workforce. Steady progress has been made on maternal and child health. And the country is better buttressed against the destructive forces posed by climate change and natural disasters. Bangladesh's success comprises many moving parts—from investing in human capital to establishing macroeconomic stability. Building on this success, the country is now setting the stage for further economic growth and job creation by ramping up investments in energy, inland connectivity, urban projects, and transport infrastructure, as well as focusing on climate change adaptation and disaster preparedness on its path toward sustainable growth. In 2022, Bangladesh had the second largest foreign-exchange reserves in South Asia. The reserves have boosted the government's spending capacity despite tax revenues forming only 7.7% of government revenue. A big chunk of investments have gone into the power sector. In 2009, Bangladesh was experiencing daily blackouts several times a day. In 2022, the country achieved 100% electrification. One of the major anti-poverty schemes of the Bangladeshi government is the Ashrayan Project which aims to eradicate homelessness by providing free housing. The poverty rate has gone down from 80% in 1971, to 44.2% in 1991, to 12.9% in 2021. The literacy rate was 74.66% in 2022. Bangladesh has a labor force of roughly 70 million, which is the world's seventh-largest; with an unemployment rate of 5.2% . The government is setting up 100 special economic zones to attract foreign direct investment (FDI) and generate 10 million jobs. The Bangladesh Investment Development Authority (BIDA) and the Bangladesh Economic Zones Authority (BEZA) have been established to help investors in setting up factories; and to complement the longstanding Bangladesh Export Processing Zone Authority (BEPZA). The Bangladeshi taka is the national currency. The service sector accounts for about 51.3% of total GDP and employs 39% of the workforce. The industrial sector accounts for 35.1% of GDP and employs 20.4% of the workforce. The agriculture sector makes up 13.6% of the economy but is the biggest employment sector, with 40.6% of the workforce. In agriculture, the country is a major producer of rice, fish, tea, fruits, vegetables, flowers, and jute. Lobsters and shrimps are some of Bangladesh's well-known exports. Private sector The private sector accounts for 80% of GDP compared to the dwindling role of state-owned companies. Bangladesh's economy is dominated by family-owned conglomerates and small and medium-sized businesses. Some of the largest publicly traded companies in Bangladesh include Beximco, BRAC Bank, BSRM, GPH Ispat, Grameenphone, Summit Group, and Square Pharmaceuticals. Capital markets include the Dhaka Stock Exchange and the Chittagong Stock Exchange. Its telecommunications industry is one of the world's fastest-growing, with 171.854 million cellphone subscribers in January 2021. Over 80% of Bangladesh's export earnings come from the garments industry. Other major industries include shipbuilding, pharmaceuticals, steel, ceramics, electronics, and leather goods. Muhammad Aziz Khan became the first person from Bangladesh to be listed as a billionaire by Forbes. Infrastructure Since 2009, Bangladesh has embarked on a series of megaprojects. The 6.15 km long Padma Bridge was built for US$3.86 billion. The bridge was the first self-financed megaproject in the country's history. Other megaprojects include the Dhaka Metro, Karnaphuli Tunnel, Dhaka Elevated Expressway and Chittagong Elevated Expressway; as well as the Bangladesh Delta Plan to mitigate the impact of climate change. Tourism The tourism industry is expanding, contributing some 3.02% of total GDP. Bangladesh's international tourism receipts in 2019 amounted to $391 million. The country has three UNESCO World Heritage Sites (the Mosque City, the Paharpur Buddhist Ruins and the Sundarbans) and five tentative-list sites. Activities for tourists include angling, water skiing, river cruising, hiking, rowing, yachting, and beachgoing. The World Travel and Tourism Council (WTTC) reported in 2019 that the travel and tourism industry in Bangladesh directly generated 1,180,500 jobs in 2018 or 1.9% of the country's total employment. According to the same report, Bangladesh experiences around 125,000 international tourist arrivals per year. Domestic spending generated 97.7 percent of direct travel and tourism gross domestic product (GDP) in 2012. Energy and electricity Bangladesh is gradually transitioning to a green economy. It has the largest off-grid solar power programme in the world, benefiting 20 million people. An electric car called the Palki is being developed for production in the country. Biogas is being used to produce organic fertilizer. Bangladesh continues to have huge untapped reserves of natural gas, particularly in its maritime territory. A lack of exploration and decreasing proven reserves have forced Bangladesh to import LNG from abroad. Gas shortages were further exasperated by the Russia-Ukraine War. While government-owned companies in Bangladesh generate nearly half of Bangladesh's electricity, privately owned companies like the Summit Group and Orion Group are playing an increasingly important role in both generating electricity, and supplying machinery, reactors, and equipment. Bangladesh increased electricity production from 5 gigawatts in 2009 to 25.5 gigawatts in 2022. It plans to produce 50 gigawatts by 2041. U.S. companies like Chevron and General Electric supply around 55% of Bangladesh's domestic natural gas production and are among the largest investors in power projects. 80% of Bangladesh's installed gas-fired power generation capacity comes from turbines manufactured in the United States. On 4 October 2022, the national grid collapsed and plunged the entire country into a nationwide blackout lasting eight hours. The government's investigation focused on technical failure, negligence, and possible sabotage. The investigation found that grid capacity has not kept up with the expansion of electricity generation and the opening of new power plants. Gas shortages were also to blame. The electricity sector in Bangladesh is heavily reliant on natural gas. Gas shortages forced the government to import LNG from abroad. As a result, Texas-based Excelerate Energy opened Bangladesh's first floating LNG terminal in 2018 off the coast of Maheshkhali Island. The Summit LNG Terminal was opened in 2019. The Government of Bangladesh has subsidized LNG imports worth several billion dollars. Since October 2021, Bangladesh imported LNG for US$30–37 per million Btu which is 10 times the price it paid in May 2020. The government stopped buying spot price LNG in June 2022. The country's forex reserves declined due to surging fuel imports. Bangladesh imported 30% of its LNG on the spot price market in 2022, down from 40% in 2021. Bangladesh continues to trade in LNG on the futures exchange markets. The Rooppur Nuclear Power Plant, Bangladesh's first operational nuclear plant, is nearing completion as of the end of 2023. Demographics According to the 2022 Census, Bangladesh has a population of 165.1 million, and is the eighth-most-populous country in the world, the fifth-most populous country in Asia, and the most densely populated large country in the world, with a headline population density of 1,265 people/km2 . Its total fertility rate (TFR), once among the highest in the world, has experienced a dramatic decline, from 5.5 in 1985 to 3.7 in 1995, down to 2.0 in 2020, which is below the sub-replacement fertility of 2.1. The vast majority of Bangladeshis live in rural areas, with only 39% of the population living in urban areas . It has a median age of roughly 28 years, with 26% of the total population aged 14 or younger, and merely 5% aged 65 and above. Bangladesh is an ethnically and culturally homogeneous society, as Bengalis form 99% of the population. The Adivasi population includes the Chakmas, Marmas, Santhals, Mros, Tanchangyas, Bawms, Tripuris, Khasis, Khumis, Kukis, Garos, and Bisnupriya Manipuris. The Chittagong Hill Tracts region experienced unrest and an insurgency from 1975 to 1997 in an autonomy movement by its indigenous people. Although a peace accord was signed in 1997, the region remains militarised. Urdu-speaking stranded Pakistanis were given citizenship by the Supreme Court in 2008. Bangladesh also hosts over 700,000 Rohingya refugees since 2017, giving it one of the largest refugee populations in the world. Urban centres Bangladesh's capital Dhaka and the largest city and is overseen by two city corporations that manage between them the northern and southern parts of the city. There are 12 city corporations which hold mayoral elections: Dhaka South, Dhaka North, Chittagong, Comilla, Khulna, Mymensingh, Sylhet, Rajshahi, Barisal, Rangpur, Gazipur and Narayanganj. Mayors are elected for five-year terms. Altogether there are 506 urban centres in Bangladesh which 43 cities have a population of more than 100,000. Language The official and predominant language of Bangladesh is Bengali, which is spoken by more than 98% of the population as their native language. Bengali is described as a dialect continuum where there are various dialects spoken throughout the country. There is a diglossia in which much of the population is able to understand or speak Standard Colloquial Bengali, and in their regional dialects. These include Chittagonian or Sylheti, though some linguists consider them as separate languages. English plays an important role in Bangladesh's judicial and educational affairs, due to the country's history as part of the British Empire. It is widely spoken and commonly understood, and is taught as a compulsory subject in all schools, colleges and universities, while the English-medium educational system is widely attended. Tribal languages, although increasingly endangered, include the Chakma language, another native Eastern Indo-Aryan language, spoken by the Chakma people. Others are Garo, Meitei, Kokborok and Rakhine. Among the Austroasiatic languages, the most spoken is the Santali language, native to the Santal people. The stranded Pakistanis and some sections of the Old Dhakaites often use Urdu as their native tongue, but the usage of the latter remains highly reproached. Religion Bangladesh was constitutionally proclaimed as the first secular state of South Asia in 1972. It grants freedom of religion and claims to be "secular in practise" while establishing Islam as the state religion. The constitution bans religion-based politics and discrimination, and proclaims equal recognition of people adhering to all faiths. Islam is the largest religion across the country, being followed by about 91.1% of the population. The vast majority of Bangladeshi citizens are Bengali Muslims, adhering to Sunni Islam. The country is the third-most populous Muslim-majority state in the world and has the fourth-largest overall Muslim population. Hinduism is followed by 7.9% of the population, mainly by the Bengali Hindus, who form the country's second-largest religious group and the third-largest Hindu community globally, after those in India and Nepal. Buddhism is the third-largest religion, at 0.6% of the population. Bangladeshi Buddhists are concentrated among the tribal ethnic groups in the Chittagong Hill Tracts. At the same time, coastal Chittagong is home to many Bengali Buddhists. Christianity is the fourth-largest religion at 0.3%, followed mainly by a small Bengali Christian minority. 0.1% of the population practices other religions like Animism or is irreligious. Education The constitution states that all children shall receive free and compulsory education. Education in Bangladesh is overseen by the Ministry of Education. The Ministry of Primary and Mass Education is responsible for implementing policy for primary education and state-funded schools at a local level. Primary and secondary education is compulsory, and is financed by the state and free of charge in public schools. Bangladesh has a literacy rate of 74.7% per cent as of 2019: 77.4% for males and 71.9% for females. The country's educational system is three-tiered and heavily subsidised, with the government operating many schools at the primary, secondary and higher secondary levels and subsidising many private schools. In the tertiary education sector, the Bangladeshi government funds over 45 state universities through the University Grants Commission (UGC), created by Presidential Order 10 in 1973. The education system is divided into five levels: primary (first to fifth grade), junior secondary (sixth to eighth grade), secondary (ninth and tenth grade), higher secondary (11th and 12th grade), and tertiary which is university level. According to Hossain 2016, the formal schooling of secondary education in Bangladesh is seven years. The first three years are called junior secondary and include grades six to eight. The next two years are called secondary and include grades nine and ten. The final two years are called higher secondary and include grade eleven and twelve. Based on the information from Hossain 2016 and Daily Star 2010, to pass the fifth grade the Bangladesh Education Ministry requires a public exam called Primary School Certificate (PSC). During the eighth grade students have to pass the Junior School Certificate (JSC) exam to get enrolled in ninth grade, while tenth-grade students have to pass the Secondary School Certificate (SSC) exam to proceed to eleventh grade. Lastly, students have to pass the Higher Secondary Certificate (HSC) exam at grade twelve to apply for university. Universities in Bangladesh are of three general types: public (government-owned and subsidised), private (privately owned universities) and international (operated and funded by international organisations). The country has 47 public, 105 private and two international universities; Bangladesh National University has the largest enrolment, and the University of Dhaka (established in 1921) is the oldest. Bangladesh University of Engineering and Technology (BUET) is a premiere university for engineering education. University of Chittagong, established in 1966, has the largest campus. Dhaka College, established in 1841, is the oldest educational institution for higher education in Bangladesh. Medical education is provided by 29 government and private medical colleges. All medical colleges are affiliated with the Ministry of Health and Family Welfare. Bangladesh was ranked 105th in the Global Innovation Index in 2023. Health Bangladesh, by the constitution, guarantees healthcare services as a fundamental right to all of its citizens. The Ministry of Health and Family Welfare is the largest institutional healthcare provider in Bangladesh, and contains two divisions: Health Service Division and Medical Education And Family Welfare Division. However, healthcare facilities in Bangladesh are considered less than adequate, although they have improved as the economy has grown and poverty levels have decreased significantly. Bangladesh faces a severe health workforce crisis, as formally-trained providers make up a short percentage of the total health workforce. Significant deficiencies in the treatment practices of village doctors persist, with widespread harmful and inappropriate drug prescribing. Bangladesh's poor healthcare system suffers from severe underfunding from the government. , some 2.48% of total GDP was attributed to healthcare, and domestic general government spending on healthcare was 18.63% of the total budget, while out-of-pocket expenditures made up the vast majority of the total budget, totalling 72.68%. Domestic private health expenditure was about 75% of the total healthcare expenditure. , there are only 5.3 doctors per 10,000 people, and about six physicians and three nurses per 10,000 people, while the number of hospital beds is 8 per 10,000. The overall life expectancy in Bangladesh at birth was 73 years (71 years for males and 75 years for females) , and it has a comparably high infant mortality rate (24 per 1,000 live births) and child mortality rate (29 per 1,000 live births). Maternal mortality remains high, clocking at 173 per 100,000 live births. Bangladesh is a key source market for medical tourism for various countries, mainly India, due to its citizens dissatisfaction and distrust over their own healthcare system. The main causes of death are coronary artery disease, stroke, and chronic respiratory disease; comprising 62% and 60% of all adult male and female deaths, respectively. Malnutrition is a major and persistent problem in Bangladesh, mainly affecting the rural regions, more than half of the population suffers from it. Severe acute malnutrition affects 450,000 children, while nearly 2 million children have moderate acute malnutrition. For children under the age of five, 52% are affected by anaemia, 41% are stunted, 16% are wasted, and 36% are underweight. A quarter of women are underweight and around 15% have short stature, while over half also suffer from anaemia. Culture Visual arts and crafts The recorded history of art in Bangladesh can be traced to the 3rd century BCE, when terracotta sculptures were made in the region. In classical antiquity, notable sculptural Hindu, Jain, and Buddhist art developed in the Pala Empire and the Sena dynasty. Islamic art has evolved since the 14th century. The architecture of the Bengal Sultanate saw a distinct style of domed mosques with complex niche pillars that had no minarets. Mughal Bengal's most celebrated artistic tradition was the weaving of Jamdani motifs on fine muslin, which is now classified by UNESCO as an intangible cultural heritage. Jamdani motifs were similar to Iranian textile art (buta motifs) and Western textile art (paisley). The Jamdani weavers in Dhaka received imperial patronage. Ivory and brass were also widely used in Mughal art. Pottery is thoroughly used in Bengali culture. The modern art movement in Bangladesh took shape during the 1950s, particularly with the pioneering works of Zainul Abedin. East Bengal developed its own modernist painting and sculpture traditions, which were distinct from the art movements in West Bengal. The Art Institute Dhaka has been a significant centre for visual art in the region. Its annual Bengali New Year parade was enlisted as an intangible cultural heritage by UNESCO in 2016. Modern Bangladesh has produced many of South Asia's leading painters, including SM Sultan, Mohammad Kibria, Shahabuddin Ahmed, Kanak Chanpa Chakma, Kafil Ahmed, Saifuddin Ahmed, Qayyum Chowdhury, Rashid Choudhury, Quamrul Hassan, Rafiqun Nabi and Syed Jahangir, among others. Novera Ahmed and Nitun Kundu were the country's pioneers of modernist sculpture. In recent times, photography as a medium of art has become popular. Biennial Chobi Mela is considered the largest photography festival in Asia. Literature Bengali literature is a millennium-old tradition; the Charyapadas are the earliest examples of Bengali poetry. Sufi spiritualism inspired many Bengali Muslim writers. During the Bengal Sultanate, medieval Bengali writers were influenced by Arabic and Persian works. Sultans of Bengal patronized Bengali literature. Examples include the writings of Maladhar Basu, Bipradas Pipilai, Vijay Gupta, and Yasoraj Khan. The Chandidas are notable lyric poets from the early Medieval Age. Syed Alaol was the bard of Middle Bengali literature. The Bengal Renaissance shaped modern Bengali literature, including novels, short stories, and science fiction. Rabindranath Tagore was the first non-European laureate of the Nobel Prize in Literature and is described as the Bengali Shakespeare. Kazi Nazrul Islam was a revolutionary poet who espoused political rebellion against colonialism and fascism. Begum Rokeya is regarded as the pioneer feminist writer of Bangladesh. Other renaissance icons included Michael Madhusudan Dutt and Sarat Chandra Chattopadhyay. The writer Syed Mujtaba Ali is noted for his cosmopolitan Bengali worldview. Jasimuddin was a renowned pastoral poet. Shamsur Rahman and Al Mahmud are considered two of the greatest Bengali poets to have emerged in the 20th century. Farrukh Ahmad, Sufia Kamal, Syed Ali Ahsan, Ahsan Habib, Abul Hussain, Shahid Qadri, Fazal Shahabuddin, Abu Zafar Obaidullah, Omar Ali, Al Mujahidi, Syed Shamsul Huq, Nirmalendu Goon, Abid Azad, Hasan Hafizur Rahman and Abdul Hye Sikder are important figures of modern Bangladeshi poetry. Ahmed Sofa is regarded as the most important Bangladeshi intellectual in the post-independence era. Humayun Ahmed was a popular writer of modern Bangladeshi magical realism and science fiction. Notable writers of Bangladeshi fictions include Mir Mosharraf Hossain, Akhteruzzaman Elias, Alauddin Al Azad, Shahidul Zahir, Rashid Karim, Mahmudul Haque, Syed Waliullah, Shahidullah Kaiser, Shawkat Osman, Selina Hossain, Shahed Ali, Razia Khan, Anisul Hoque, and Abdul Mannan Syed. The annual Ekushey Book Fair and Dhaka Literature Festival, organised by the Bangla Academy, are among the enormous literary festivals in South Asia. Women Although , several women occupied a key political office in Bangladesh. Its women continue to live under a patriarchal social regime where violence is common. Whereas in India and Pakistan, women participate less in the workforce as their education increases, the reverse is the case in Bangladesh. Bengal has a long history of feminist activism dating back to the 19th century. Begum Rokeya and Faizunnessa Chowdhurani played an important role in emancipating Bengali Muslim women from purdah, before the country's division, as well as promoting girls' education. Several women were elected to the Bengal Legislative Assembly in the British Raj. The first women's magazine, Begum, was published in 1948. In 2008, Bangladeshi female workforce participation stood at 26%. Women dominate blue collar jobs in the Bangladeshi garment industry. Agriculture, social services, healthcare, and education are chosen occupations for Bangladeshi women, while their employment in white collar positions has steadily increased. Architecture The architectural traditions of Bangladesh have a 2,500-year-old heritage. Terracotta architecture is a distinct feature of Bengal. Pre-Islamic Bengali architecture reached its pinnacle in the Pala Empire when the Pala School of Sculptural Art established grand structures such as the Somapura Mahavihara. Islamic architecture began developing under the Bengal Sultanate, when local terracotta styles influenced medieval mosque construction. The Sixty Dome Mosque was the largest medieval mosque built in Bangladesh and is a fine example of Turkic-Bengali architecture. The Mughal style replaced indigenous architecture when Bengal became a province of the Mughal Empire and influenced urban housing development. The Kantajew Temple and Dhakeshwari Temple are excellent examples of late medieval Hindu temple architecture. Indo-Saracenic Revival architecture, based on Indo-Islamic styles, flourished during the British period. The zamindar gentry in Bangladesh built numerous Indo-Saracenic palaces and country mansions, such as the Ahsan Manzil, Tajhat Palace, Dighapatia Palace, Puthia Rajbari and Natore Rajbari. Bengali vernacular architecture is noted for pioneering the bungalow. Bangladeshi villages consist of thatched roofed houses made of natural materials like mud, straw, wood, and bamboo. In modern times, village bungalows are increasingly made of tin. Muzharul Islam was the pioneer of Bangladeshi modern architecture. His varied works set the course of modern architectural practice in the country. Islam brought leading global architects, including Louis Kahn, Richard Neutra, Stanley Tigerman, Paul Rudolph, Robert Boughey and Konstantinos Doxiadis, to work in erstwhile East Pakistan. Louis Kahn was chosen to design the National Parliament Complex in Sher-e-Bangla Nagar. Kahn's monumental designs, combining regional red brick aesthetics, his concrete and marble brutalism and the use of lakes to represent Bengali geography, are regarded as one of the masterpieces of the 20th century. In recent times, award-winning architects like Rafiq Azam have set the course of contemporary architecture by adopting influences from the works of Islam and Kahn. Performing arts Theatre in Bangladesh includes various forms with a history dating back to the 4th century CE. It includes narrative forms, song and dance forms, supra-personae forms, performances with scroll paintings, puppet theatre and processional forms. The Jatra is the most popular form of Bengali folk theatre. The dance traditions of Bangladesh include indigenous tribal and Bengali dance forms, as well as classical Indian dances, including the Kathak, Odissi and Manipuri dances. The music of Bangladesh features the Baul mystical tradition, listed by UNESCO as a Masterpiece of Intangible Cultural Heritage. Fakir Lalon Shah popularised Baul music in the country in the 18th century and it has since been one of the most popular music genres in the country since then. Most modern Bauls are devoted to Lalon Shah. Numerous lyric-based musical traditions, varying from one region to the next, exist, including Gombhira, Bhatiali and Bhawaiya. Folk music is accompanied by a one-stringed instrument known as the ektara. Other instruments include the dotara, dhol, flute, and tabla. Bengali classical music includes Tagore songs and Nazrul Sangeet. Bangladesh has a rich tradition of Indian classical music, which uses instruments like the sitar, tabla, sarod, and santoor. Sabina Yasmin and Runa Laila were considered the leading playback singers in the 1990s, while musicians such as Ayub Bachchu and James are credited with popularising rock music in Bangladesh. Textiles The Nakshi Kantha is a centuries-old embroidery tradition for quilts, said to be indigenous to eastern Bengal (Bangladesh). The sari is the national dress for Bangladeshi women. Mughal Dhaka was renowned for producing the finest muslin saris, as well as the famed Dhakai and Jamdani, the weaving of which is listed by UNESCO as one of the masterpieces of humanity's intangible cultural heritage. Bangladesh also produces the Rajshahi silk. The shalwar kameez is also widely worn by Bangladeshi women. In urban areas, some women can be seen in Western clothing. The kurta and sherwani are the national dress of Bangladeshi men; the lungi and dhoti are worn in informal settings. Aside from ethnic wear, domestically tailored suits and neckties are customarily worn by the country's men in offices, in schools, and at social events. The handloom industry supplies 60–65% of the country's clothing demand. The Bengali ethnic fashion industry has flourished. The retailer Aarong is one of South Asia's most successful ethnic wear brands. The development of the Bangladesh textile industry, which supplies leading international brands, has promoted the local production and retail of modern Western attire. The country now has several expanding local brands like Westecs and Yellow. Bangladesh is the world's second-largest garment exporter. Among Bangladesh's fashion designers, Bibi Russell has received international acclaim for her "Fashion for Development" shows. Cuisine Bangladeshi cuisine, formed by its geographic location and climate, is rich and diverse; sharing its culinary heritage with the neighbouring Indian state of West Bengal. White rice is the staple, and along with fish, forms the culinary base. Varieties of leaf vegetables, potatoes, gourds and lentils (dal) also play an important role. Curries of beef, mutton, chicken and duck are commonly consumed, along with multiple types of bhortas, bhajis and torkaris. Mughal-influenced dishes include kormas, kalias, biryanis, pulaos, teharis and khichuris. Among the various spices, turmeric, fenugreek, nigella, coriander, anise, cardamom and chili powder are widely used; a famous spice mix is the panch phoron. Condiments and herbs used include red onions, green chillies, garlic, ginger, cilantro, and mint. Coconut milk, mustard paste, mustard seeds, mustard oil, ghee, achars and chutneys are also widely used in the cuisine. Fish is the main source of protein, owing to the country's riverine geography, and it is often enjoyed with its roe. The hilsa is the national fish and is immensely popular; a famous dish is shorshe ilish. Rohu, pangas, tilapia, lobsters, shrimps and dried fish (shutki) are also widely consumed, with the chingri malai curry being a famous shrimp dish. In Chittagong, famous dishes include kala bhuna and mezban, the latter being a traditionally popular feast, featuring the serving of mezbani gosht, a hot and spicy beef curry. In Sylhet, the shatkora lemons are used to marinate dishes, a notable one is beef hatkora. Among the tribal communities in the Chittagong Hill Tracts, cooking with bamboo shoots is popular. Khulna is renowned for using chui jhal (piper chaba) in its meat-based dishes. Bangladesh has a vast spread of desserts, including distinctive sweets such as the rôshogolla, roshmalai, chomchom, sondesh, mishti doi and kalojaam, and jilapi. Pithas are traditional boiled desserts made with rice or fruits. Halwa and shemai, the latter being a variation of vermicelli; are popular desserts during religious festivities. Ruti, naan, paratha, luchi and bakarkhani are the main local breads. Hot milk tea is the most commonly consumed beverage in the country, being the centre of addas. Borhani, mattha and lassi are popular traditionally consumed beverages. Kebabs are widely popular, particularly seekh kebab, chapli kebab, shami kebab, chicken tikka and shashlik, along with various types of chaaps. Popular street foods include chotpoti, jhal muri and fuchka. Festivals Pahela Baishakh, the Bengali new year, is the major festival of Bengali culture and sees widespread festivities. Of the major holidays celebrated in Bangladesh, only Pahela Baishakh comes without any pre-existing expectations (specific religious identity, a culture of gift-giving, etc.) and has become an occasion for celebrating the simpler, rural roots of Bengal. Other cultural festivals include Nabonno and Poush Parbon, Bengali harvest festivals. The Muslim festivals of Eid al-Fitr, Eid al-Adha, Mawlid, Muharram, Chand Raat, Shab-e-Barat; the Hindu festivals of Durga Puja, Janmashtami and Rath Yatra; the Buddhist festival of Buddha Purnima, which marks the birth of Gautama Buddha, and the Christian festival of Christmas are national holidays in Bangladesh and see the most widespread celebrations in the country. The two Eids are celebrated with a long streak of public holidays and allow celebrating the festivals with their families outside the city. Alongside national days like the remembrance of 21 February 1952 Language Movement Day (declared as International Mother Language Day by UNESCO in 1999), Independence Day and Victory Day. On Language Movement Day, people congregate at the Shaheed Minar in Dhaka to remember the national heroes of the Bengali Language Movement. Similar gatherings are observed at the National Martyrs' Memorial on Independence Day and Victory Day to remember the national heroes of the Bangladesh Liberation War. Sports In rural Bangladesh, several traditional indigenous sports such as Kabaddi, Boli Khela, Lathi Khela and Nouka Baich remain fairly popular. While Kabaddi is the national sport, Cricket is the most popular sport in the country. The national cricket team participated in their first Cricket World Cup in 1999 and the following year was granted Test cricket status. Bangladesh reached the quarter-final of the 2015 Cricket World Cup, the semi-final of the 2017 ICC Champions Trophy and they reached the final of the Asia Cup 3 times – in 2012, 2016, and 2018. Shakib Al Hasan is widely regarded as one of the greatest All-rounders in the history of Cricket and as one of the greatest Bangladeshi sportsman ever. On 9 February 2020, the Bangladesh youth national cricket team won the men's Under-19 Cricket World Cup, held in South Africa. This was Bangladesh's first World Cup victory. Women's Cricket saw significant progress in the 2010s decade in Bangladesh. In 2018, the Bangladesh women's national cricket team won the 2018 Women's Twenty20 Asia Cup defeating India women's national cricket team in the final. Football is also a leading sport in Bangladesh. Although football was seen as the most popular sport in the country before the 21st century, success in cricket has overshadowed its previous popularity. The first instance of a national football team was the emergence of the Shadhin Bangla Team, which played friendly matches throughout India to raise international awareness about the Bangladesh Liberation War in 1971. On 26 July 1971, the team's captain, Zakaria Pintoo, became the first person to hoist the Bangladesh flag on foreign land before their match in Nadia district of West Bengal. Following independence, the national football team participated in the AFC Asian Cup (1980), becoming only the second South Asian team to do so. Bangladesh's most notable achievements in football include the 2003 SAFF Gold Cup and 1999 South Asian Games. In 2022, the Bangladesh women's national football team won the 2022 SAFF Women's Championship. Bangladesh archers Ety Khatun and Roman Sana won several gold medals winning all the 10 archery events (both individual and team events) in the 2019 South Asian Games. The National Sports Council regulates 42 sporting federations. Chess is very popular in Bangladesh. Bangladesh has five grandmasters in chess. Among them, Niaz Murshed was the first grandmaster in South Asia. In 2010, mountain climber Musa Ibrahim became the first Bangladeshi climber to conquer Mount Everest. Wasfia Nazreen is the first Bangladeshi climber to climb the Seven Summits. Bangladesh hosts several international tournaments. Bangabandhu Cup is an international football tournament hosted in the country. Bangladesh hosted the South Asian Games several times. In 2011, Bangladesh co-hosted the ICC Cricket World Cup 2011 with India and Sri Lanka. Bangladesh solely hosted the 2014 ICC World Twenty20 championship. Bangladesh hosted the Asia Cup Cricket Tournament in 2000, 2012, 2014 and 2016. Media and cinema The Bangladeshi press is diverse and privately owned. Over 200 newspapers are published in the country. Bangladesh Betar is a state-run radio service. The British Broadcasting Corporation operates the popular BBC Bangla news and current affairs service. Bengali broadcasts from Voice of America are also very popular. Bangladesh Television (BTV) is a state-owned television network. More than 20 privately owned television networks, including several news channels. Freedom of the media remains a major concern due to government attempts at censorship and the harassment of journalists. The cinema of Bangladesh dates back to 1898 when films began screening at the Crown Theatre in Dhaka. The Dhaka Nawab Family patronised the production of several silent films in the 1920s and 30s. In 1931, the East Bengal Cinematograph Society released the first full-length feature film in Bangladesh, titled Last Kiss. The first feature film in East Pakistan, Mukh O Mukhosh, was released in 1956. During the 1960s, 25–30 films were produced annually in Dhaka. By the 2000s, Bangladesh produced 80–100 films a year. While the Bangladeshi film industry has achieved limited commercial success, the country has produced notable independent filmmakers. Zahir Raihan was a prominent documentary maker assassinated in 1971. Tareque Masud is regarded as one of Bangladesh's outstanding directors. Masud was honoured by FIPRESCI at the 2002 Cannes Film Festival for his film The Clay Bird. Tanvir Mokammel, Mostofa Sarwar Farooki, Humayun Ahmed, Alamgir Kabir, Chashi Nazrul Islam and Sohanur Rahman Sohan, who was best known in Dhallywood for directing romantic films. His film Ananta Bhalobasha released in 1999 marked a turning point in Bangladeshi cinema by introducing Shakib Khan, who is now one of the biggest superstars in the industry, are some of the prominent directors of Bangladeshi cinema. Bangladesh has a very active film society culture. It started in 1963 in Dhaka. Now around 40 Film Societies are active all over Bangladesh. Federation of Film Societies of Bangladesh is the parent organisation of the film society movement of Bangladesh. Active film societies include the Rainbow Film Society, Children's Film Society, Moviyana Film Society, and Dhaka University Film Society. Museums and libraries The Varendra Research Museum is the oldest museum in Bangladesh. It houses important collections from both the pre-Islamic and Islamic periods, including the sculptures of the Pala-Sena School of Art and the Indus Valley civilisation, and Sanskrit, Arabic, and Persian manuscripts and inscriptions. The Ahsan Manzil, the former residence of the Nawab of Dhaka, is a national museum housing collections from the British Raj. The Tajhat Palace Museum preserves artifacts of the rich cultural heritage of North Bengal, including Hindu-Buddhist sculptures and Islamic manuscripts. The Mymensingh Museum houses the personal antique collections of Bengali aristocrats in central Bengal. The Ethnological Museum of Chittagong showcases the lifestyle of various tribes in Bangladesh. The Bangladesh National Museum is located in Ramna, Dhaka, and has a rich collection of antiquities. The Liberation War Museum documents the Bangladeshi struggle for independence and the 1971 genocide. The Hussain Shahi dynasty established royal libraries during the Bengal Sultanate. Libraries were established in each district of Bengal by the Zamindar gentry during the Bengal Renaissance in the 19th century. The trend of establishing libraries continued until the beginning of World War II. In 1854, four major public libraries were opened, including the Bogra Woodburn Library, the Rangpur Public Library, the Jessore Institute Public Library, and the Barisal Public Library. The Northbrook Hall Public Library was established in Dhaka in 1882 in honour of Lord Northbrook, the Governor-General. Other libraries inaugurated in the British period included the Victoria Public Library, Natore (1901), the Sirajganj Public Library (1882), the Rajshahi Public Library (1884), the Comilla Birchandra Library (1885), the Shah Makhdum Institute Public Library, Rajshahi (1891), the Noakhali Town Hall Public Library (1896), the Prize Memorial Library, Sylhet (1897), the Chittagong Municipality Public Library (1904) and the Varendra Research Library (1910). The Great Bengal Library Association was formed in 1925. The Central Public Library of Dhaka was established in 1959. The National Library of Bangladesh was established in 1972. The World Literature Centre, founded by Ramon Magsaysay Award winner Abdullah Abu Sayeed, is noted for operating numerous mobile libraries across Bangladesh and was awarded the UNESCO Jon, Amos Comenius Medal.

Barbados

Barbados ( ; ; ) is an island country in the Lesser Antilles of the West Indies, in the Caribbean region of North America and the most easterly of the Caribbean Islands. It lies on the boundary of the South American and the Caribbean Plates. Its capital and largest city is Bridgetown. Inhabited by Kalinago people since the 13th century, and prior to that by other Amerindians, Spanish navigators took possession of Barbados in the late 15th century, claiming it for the Crown of Castile. It first appeared on a Spanish map in 1511. The Portuguese Empire claimed the island between 1532 and 1536, but abandoned it in 1620 with their only remnants being an introduction of wild boars for a good supply of meat whenever the island was visited. An English ship, the Olive Blossom, arrived in Barbados on 14 May 1625; its men took possession of the island in the name of King James I. In 1627, the first permanent settlers arrived from England, and Barbados became an English and later British colony. During this period, the colony operated on a plantation economy, relying on the labour of African slaves who worked on the island's plantations. Slavery continued until it was phased out through most of the British Empire by the Slavery Abolition Act 1833. On 30 November 1966, Barbados gained independence and became a Commonwealth realm with Elizabeth II as Queen of Barbados. On 30 November 2021, Barbados transitioned to a republic within the Commonwealth. Barbados's population is predominantly of African ancestry. While it is technically an Atlantic island, Barbados is closely associated with the Caribbean and is ranked as one of its leading tourist destinations. Etymology The name "Barbados" is from either the Portuguese term or the Spanish equivalent, , both meaning "the bearded ones". It is unclear whether "bearded" refers to the long, hanging roots of the bearded fig-tree (Ficus citrifolia), a species of banyan indigenous to the island, or to the allegedly bearded Caribs who once inhabited the island, or, more fancifully, to a visual impression of a beard formed by the sea foam that sprays over the outlying coral reefs. In 1519, a map produced by the Genoese mapmaker Visconte Maggiolo showed and named Barbados in its correct position. Furthermore, the island of Barbuda in the Leewards is very similar in name and was once named "" by the Spanish. The original name for Barbados in the Pre-Columbian era was , according to accounts by descendants of the indigenous Arawakan-speaking tribes in other regional areas, with possible translations including "Red land with white teeth" or "Redstone island with teeth outside (reefs)" or simply "Teeth". Colloquially, Barbadians refer to their home island as "Bim" or other nicknames associated with Barbados, including "Bimshire". The origin is uncertain, but several theories exist. The National Cultural Foundation of Barbados says that "Bim" was a word commonly used by slaves, and that it derives from the Igbo term from meaning "my home, kindred, kind"; the Igbo phoneme in the Igbo orthography is very close to . The name could have arisen due to the relatively large percentage of Igbo slaves from modern-day southeastern Nigeria arriving in Barbados in the 18th century. The words "Bim" and "Bimshire" are recorded in the Oxford English Dictionary and Chambers Twentieth Century Dictionaries. Another possible source for "Bim" is reported to be in the Agricultural Reporter of 25 April 1868, where the Rev. N. Greenidge (father of one of the island's most famous scholars, Abel Hendy Jones Greenidge) suggested that Bimshire was "introduced by an old planter listing it as a county of England". Expressly named were "Wiltshire, Hampshire, Berkshire and Bimshire". Lastly, in the Daily Argosy (of Demerara, i.e. Guyana) of 1652, there is a reference to Bim as a possible corruption of "Byam", the name of a Royalist leader against the Parliamentarians. That source suggested the followers of Byam became known as "Bims" and that this became a word for all Barbadians. History Geological history About 700 thousand years ago, the island emerged from the ocean as a result of a rising body of soft rock in the mantle known as a diapir, located under Barbados, pushing it upwards. This process is still happening, and makes the island rise about 30 centimeters on average every thousand years. Currently, dozens of inland sea reefs still dominate coastal features within terraces and cliffs of the island. Pre-colonial period Archeological evidence suggests humans may have first settled or visited the island circa 1600 BC. More permanent Amerindian settlement of Barbados dates to about the 4th to 7th centuries AD, by a group known as the Saladoid-Barrancoid. Settlements of Arawaks from South America appeared by around 800 AD and again in the 12th–13th century. The Kalinago (called "Caribs" by the Spanish) visited the island regularly, although there is no evidence of permanent settlement. European arrival It is uncertain which European nation arrived first in Barbados, which probably would have been at some point in the 15th century or 16th century. One lesser-known source points to earlier revealed works antedating contemporary sources, indicating it could have been the Spanish. Many, if not most, believe the Portuguese, en route to Brazil, were the first Europeans to come upon the island. The island was largely ignored by Europeans, though Spanish slave raiding is thought to have reduced the native population, with many fleeing to other islands. English settlement in the 17th century The first English ship, which had arrived on 14 May 1625, was captained by John Powell. The first settlement began on 17 February 1627, near what is now Holetown (formerly Jamestown, after King James I of England), by a group led by John Powell's younger brother, Henry, consisting of 80 settlers and 10 English indentured labourers. Some sources state that some Africans were amongst these first settlers. The settlement was established as a proprietary colony and funded by Sir William Courten, a City of London merchant who acquired the title to Barbados and several other islands. The first colonists were actually tenants, and much of the profits of their labour returned to Courten and his company. Courten's title was later transferred to James Hay, 1st Earl of Carlisle, in what was called the "Great Barbados Robbery". Carlisle then chose as governor Henry Powell, who established the House of Assembly in 1639, in an effort to appease the planters, who might otherwise have opposed his controversial appointment. In the period 1640–1660, the West Indies attracted more than two-thirds of the total number of English emigrants to the Americas. By 1650, there were 44,000 settlers in the West Indies, as compared to 12,000 on the Chesapeake and 23,000 in New England. Most English arrivals were indentured. After five years of labour, they were given "freedom dues" of about £10, usually in goods. Before the mid-1630s, they also received of land, but after that time the island filled and there was no more free land. During the Cromwellian era (1650s) this included a large number of prisoners-of-war, vagrants and people who were illicitly kidnapped, who were forcibly transported to the island and sold as servants. These last two groups were predominantly Irish, as several thousand were infamously rounded up by English merchants and sold into servitude in Barbados and other Caribbean islands during this period, a practice that came to be known as being Barbadosed. Cultivation of tobacco, cotton, ginger and indigo was thus handled primarily by European indentured labour until the start of the sugar cane industry in the 1640s and the growing reliance on and importation of African slaves. Parish registers from the 1650s show that, for the white population, there were four times as many deaths as marriages. The mainstay of the infant colony's economy was the growth export of tobacco, but tobacco prices eventually fell in the 1630s as Chesapeake production expanded. Effects of the English Civil War Around the same time, fighting during the War of the Three Kingdoms and the Interregnum spilled over into Barbados and Barbadian territorial waters. The island was not involved in the war until after the execution of Charles I, when the island's government fell under the control of Royalists (ironically the Governor, Philip Bell, remaining loyal to Parliament while the Barbadian House of Assembly, under the influence of Humphrey Walrond, supported Charles II). To try to bring the recalcitrant colony to heel, the Commonwealth Parliament passed an act on 3 October 1650 prohibiting trade between England and Barbados, and because the island also traded with the Netherlands, further Navigation Acts were passed, prohibiting any but English vessels trading with Dutch colonies. These acts were a precursor to the First Anglo-Dutch War. The Commonwealth of England sent an invasion force under the command of Sir George Ayscue, which arrived in October 1651. Ayscue, with a smaller force that included Scottish prisoners, surprised a larger force of Royalists, but had to resort to spying and diplomacy ultimately. On 11 January 1652, the Royalists in the House of Assembly led by Lord Willoughby surrendered, which marked the end of royalist privateering as a major threat. The conditions of the surrender were incorporated into the Charter of Barbados (Treaty of Oistins), which was signed at the Mermaid's Inn, Oistins, on 17 January 1652. Irish people in Barbados Starting with Cromwell, a large percentage of the white labourer population were indentured servants and involuntarily transported people from Ireland. Irish servants in Barbados were often treated poorly, and Barbadian planters gained a reputation for cruelty. The decreased appeal of an indenture on Barbados, combined with enormous demand for labour caused by sugar cultivation, led to the use of involuntary transportation to Barbados as a punishment for crimes, or for political prisoners, and also to the kidnapping of labourers who were deported to Barbados. Irish indentured servants were a significant portion of the population throughout the period when white servants were used for plantation labour in Barbados, and while a "steady stream" of Irish servants entered the Barbados throughout the 17th century, Cromwellian efforts to pacify Ireland created a "veritable tidal wave" of Irish labourers who were sent to Barbados during the 1650s. Due to inadequate historical records, the total number of Irish labourers sent to Barbados is unknown, and estimates have been "highly contentious". While one historical source estimated that as many as 50,000 Irish people were deported to either Barbados or Virginia during the 1650s, this estimate is "quite likely exaggerated". Another estimate that 12,000 Irish prisoners had arrived in Barbados by 1655 has been described as "probably exaggerated" by historian Richard B. Sheridan. According to historian Thomas Bartlett, it is "generally accepted" that approximately 10,000 Irish were deported to the West Indies and approximately 40,000 came as voluntary indentured servants, while many also travelled as voluntary, un-indentured emigrants. The sugar revolution The introduction of sugar cane from Dutch Brazil in 1640 completely transformed society, the economy and the physical landscape. Barbados eventually had one of the world's biggest sugar industries. One group instrumental in ensuring the early success of the industry was the Sephardic Jews, who had originally been expelled from the Iberian peninsula, to end up in Dutch Brazil. As the effects of the new crop increased, so did the shift in the ethnic composition of Barbados and surrounding islands. The workable sugar plantation required a large investment and a great deal of heavy labour. At first, Dutch traders supplied the equipment, financing, and African slaves, in addition to transporting most of the sugar to Europe. In 1644 the population of Barbados was estimated at 30,000, of which about 800 were of African ancestry, with the remainder mainly of English ancestry. These English smallholders were eventually bought out and the island filled up with large sugar plantations worked by African slaves. By 1660 there was near parity with 27,000 blacks and 26,000 whites. By 1666 at least 12,000 white smallholders had been bought out, died, or left the island, many choosing to emigrate to Jamaica or the American Colonies (notably the Carolinas). As a result, Barbados enacted a slave code as a way of legislatively controlling its black slave population. The law's text was influential in laws in other colonies. By 1680 there were 20,000 free whites and 46,000 enslaved Africans; by 1724, there were 18,000 free whites and 55,000 enslaved Africans. 18th and 19th centuries The harsh conditions endured by the slaves resulted in several planned slave rebellions, the largest of which was Bussa's rebellion in 1816 which was rapidly suppressed by the colonial authorities. In 1819, another slave revolt broke out on Easter Day. The revolt was put down in blood, with heads being displayed on stakes. Nevertheless, the brutality of the repression shocked even England and strengthened the abolitionist movement. Growing opposition to slavery led to its abolition in the British Empire in 1833. The plantocracy class retained control of political and economic power on the island, with most workers living in relative poverty. The 1780 hurricane killed more than 4,000 people on Barbados. In 1854, a cholera epidemic killed more than 20,000 inhabitants. 20th century before independence Deep dissatisfaction with the situation on Barbados led many to emigrate. Things came to a head in the 1930s during the Great Depression, as Barbadians began demanding better conditions for workers, the legalisation of trade unions and a widening of the franchise, which at that point was limited to male property owners. As a result of the increasing unrest the British sent a commission, called the West Indies Royal Commission, or Moyne Commission, in 1938, which recommended enacting many of the requested reforms on the islands. As a result, Afro-Barbadians began to play a much more prominent role in the colony's politics, with universal suffrage being introduced in 1950. Prominent among these early activists was Grantley Herbert Adams, who helped found the Barbados Labour Party (BLP) in 1938. He became the first Premier of Barbados in 1953, followed by fellow BLP-founder Hugh Gordon Cummins from 1958 to 1961. A group of left-leaning politicians who advocated swifter moves to independence broke off from the BLP and founded the Democratic Labour Party (DLP) in 1955. The DLP subsequently won the 1961 Barbadian general election and their leader Errol Barrow became premier. Full internal self-government was enacted in 1961. Barbados joined the short-lived West Indies Federation from 1958 to 1962, later gaining full independence on 30 November 1966. Errol Barrow became the country's first prime minister. Barbados opted to remain within the Commonwealth of Nations. The broken trident on its national flag recalls its legacy when Barbados was a British colony and symbolises that it has broken away from three centuries of colonial rule. The effect of independence meant that the Queen of the United Kingdom ceased to have sovereignty over Barbados, but the island chose to remain a constitutional monarchy with Elizabeth II as Queen of Barbados. The monarch was represented locally by a Governor-General. Post-independence era The Barrow government sought to diversify the economy away from agriculture, seeking to boost industry and the tourism sector. Barbados was also at the forefront of regional integration efforts, spearheading the creation of CARIFTA and CARICOM. The DLP lost the 1976 Barbadian general election to the BLP under Tom Adams. Adams adopted a more conservative and strongly pro-Western stance, allowing the Americans to use Barbados as the launchpad for their invasion of Grenada in 1983. Adams died in office in 1985 and was replaced by Harold Bernard St. John; however, St. John lost the 1986 Barbadian general election, which saw the return of the DLP under Errol Barrow, who had been highly critical of the US intervention in Grenada. Barrow, too, died in office, and was replaced by Lloyd Erskine Sandiford, who remained Prime Minister until 1994. Owen Arthur of the BLP won the 1994 Barbadian general election, remaining Prime Minister until 2008. Arthur was a strong advocate of republicanism, though a planned referendum to replace Queen Elizabeth as Head of State in 2008 never took place. The DLP won the 2008 Barbadian general election, but the new Prime Minister David Thompson died in 2010 and was replaced by Freundel Stuart. The BLP returned to power in 2018 under Mia Mottley, who became Barbados's first female Prime Minister. Transition to republic The Government of Barbados announced on 15 September 2020 that it intended to become a republic by 30 November 2021, the 55th anniversary of its independence resulting in the replacement of the Barbadian monarchy with an elected president. Barbados would then cease to be a Commonwealth realm, but could maintain membership in the Commonwealth of Nations, like Guyana and Trinidad and Tobago. On 20 September 2021, just over a full year after the announcement for the transition was made, the Constitution (Amendment) (No. 2) Bill, 2021 was introduced to the Parliament of Barbados. Passed on 6 October, the Bill made amendments to the Constitution of Barbados, introducing the office of the president of Barbados to replace the role of Elizabeth II as Queen of Barbados. The following week, on 12 October 2021, incumbent Governor-General of Barbados Sandra Mason was jointly nominated by the Prime Minister and Leader of the Opposition as candidate to be the first president of Barbados, and was subsequently elected on 20 October. Mason took office on 30 November 2021. Prince Charles, the heir apparent to the Barbadian Crown at the time, attended the swearing-in ceremony in Bridgetown at the invitation of the Government of Barbados. Queen Elizabeth sent a message of congratulations to President Mason and the people of Barbados, saying: "As you celebrate this momentous day, I send you and all Barbadians my warmest good wishes for your happiness, peace and prosperity in the future." A survey that was conducted between 23 October 2021, and 10 November 2021, by the University of the West Indies showed 34% of respondents being in favour of transitioning to a republic, while 30% were indifferent. Notably, no overall majority was found in the survey; with 24% not indicating a preference, and the remaining 12% being opposed to the removal of Queen Elizabeth. On 20 June 2022, a Constitutional Review Commission was formed and sworn in by Jeffrey Gibson (who, at the time, was serving temporarily as Acting President of Barbados) to review the Constitution of Barbados. The Commission will have an 18-month timeline to complete its work. They are expected to solicit input from members of the public in Barbados via a series of face-to-face and online events. Geography and climate Barbados is situated in the Atlantic Ocean, east of the other West Indies Islands. Barbados is the easternmost island in the Lesser Antilles. It is long and up to wide, covering an area of . It lies about east of both the countries of Saint Lucia and Saint Vincent and the Grenadines; south-east of Martinique and north-east of Trinidad and Tobago. It is flat in comparison to its island neighbours to the west, the Windward Islands. The island rises gently to the central highland region known as Scotland District, with the highest point being Mount Hillaby above sea level. In the parish of Saint Michael lies Barbados's capital and main city, Bridgetown, containing one third of the country's population. Other major towns scattered across the island include Holetown, in the parish of Saint James; Oistins, in the parish of Christ Church; and Speightstown, in the parish of Saint Peter. Geology Barbados lies on the boundary of the South American and the Caribbean Plates. The subduction of the South American plate beneath the Caribbean plate scrapes sediment from the South American plate and deposits it above the subduction zone forming an accretionary prism. The rate of this depositing of material allows Barbados to rise at a rate of about per 1,000 years. This subduction means geologically the island is composed of coral roughly thick, where reefs formed above the sediment. The land slopes in a series of "terraces" in the west and goes into an incline in the east. A large proportion of the island is circled by coral reefs. The erosion of limestone in the northeast of the island, in the Scotland District, has resulted in the formation of various caves and gullies. On the Atlantic east coast of the island coastal landforms, including stacks, have been created due to the limestone composition of the area. Also notable in the island is the rocky cape known as Pico Teneriffe or Pico de Tenerife, which is named after the fact that the island of Tenerife in Spain is the first land east of Barbados according to the belief of the locals. Climate The country generally experiences two seasons, one of which includes noticeably higher rainfall. Known as the "wet season", this period runs from June to December. By contrast, the "dry season" runs from December to May. Annual precipitation ranges between . From December to May the average temperatures range from , while between June and November, they range from . On the Köppen climate classification scale, much of Barbados is regarded as a tropical monsoon climate (Am). However, breezes of abound throughout the year and give Barbados a climate which is moderately tropical. Infrequent natural hazards include earthquakes, landslips, and hurricanes. Barbados lies outside the principal Atlantic hurricane belt and is often spared the worst effects of the region's tropical storms and hurricanes during the rainy season. Its location in the south-east of the Caribbean region puts the country just outside the principal hurricane strike zone. On average, a major hurricane strikes about once every 26 years. The last significant hit from a hurricane to cause severe damage to Barbados was Hurricane Janet in 1955; in 2010 the island was struck by Hurricane Tomas, but this caused only minor damage across the country as it was only at Tropical Storm level of formation. Environmental issues Barbados is susceptible to environmental pressures. As one of the world's most densely populated isles, the government worked during the 1990s to aggressively integrate the growing south coast of the island into the Bridgetown Sewage Treatment Plant to reduce contamination of offshore coral reefs. As of the first decade of the 21st century, a second treatment plant has been proposed along the island's west coast. Being so densely populated, Barbados has made great efforts to protect its underground aquifers. As a coral-limestone island, Barbados is highly permeable to seepage of surface water into the earth. The government has placed great emphasis on protecting the catchment areas that lead directly into the huge network of underground aquifers and streams. On occasion illegal squatters have breached these areas, and the government has removed squatters to preserve the cleanliness of the underground springs which provide the island's drinking water. The government has placed a huge emphasis on keeping Barbados clean with the aim of protecting the environment and preserving offshore coral reefs which surround the island. Many initiatives to mitigate human pressures on the coastal regions of Barbados and seas come from the Coastal Zone Management Unit (CZMU). Barbados has nearly of coral reefs just offshore and two protected marine parks have been established off the west coast. Overfishing is another threat which faces Barbados. Although on the opposite side of the Atlantic, and some west of Africa, Barbados is one of many places in the American continent that experience heightened levels of mineral dust from the Sahara Desert. Some particularly intense dust episodes have been blamed partly for the impacts on the health of coral reefs surrounding Barbados or asthmatic episodes, but evidence has not wholly supported the former claim. Access to biocapacity in Barbados is much lower than world average. In 2016, Barbados had 0.17 global hectares of biocapacity per person within its territory, much less than the world average of 1.6 global hectares per person. In 2016 Barbados used 0.84 global hectares of biocapacity per person - their ecological footprint of consumption. This means they use approximately five times as much biocapacity as Barbados contains. As a result, Barbados is running a biocapacity deficit. Wildlife Barbados is host to four species of nesting turtles (green turtles, loggerheads, hawksbill turtles, and leatherbacks) and has the second-largest hawksbill turtle-breeding population in the Caribbean. The driving of vehicles on beaches can crush nests buried in the sand and such activity is discouraged in nesting areas. Barbados is also the host to the green monkey. The green monkey is found in West Africa from Senegal to the Volta River. It has been introduced to the Cape Verde islands off north-western Africa, and the West Indian islands of Saint Kitts, Nevis, Saint Martin, and Barbados. It was introduced to the West Indies in the late 17th century when slave trade ships travelled to the Caribbean from West Africa. The green monkey is considered a very curious and mischievous/troublesome animal by locals. Demographics The 2010 national census conducted by the Barbados Statistical Service reported a resident population of 277,821, of which 144,803 were female and 133,018 were male. The life expectancy for Barbados residents is 80 years. The average life expectancy is 83 years for females and 79 years for males (2020). Barbados and Japan have the highest per capita occurrences of centenarians in the world. The crude birth rate is 12.23 births per 1,000 people, and the crude death rate is 8.39 deaths per 1,000 people. The infant mortality rate is 11.63 infant deaths per 1,000 live births. Ethnic groups Close to 90% of all Barbadians (also known colloquially as "Bajan") are of Afro-Caribbean ancestry ("Afro-Bajans") and mixed ancestry. The remainder of the population includes groups of Europeans ("Anglo-Bajans" / "Euro-Bajans") mainly from the United Kingdom, Ireland, Germany, and Italy. Other European groups consisted of the French, Austrians, Spaniards, and Russians. Asians, predominantly from Hong Kong and India (both Hindu and Muslim) make up less than 1% of the population. Other groups in Barbados include people from the United States and Canada. Barbadians who return after years of residence in the United States and children born in America to Bajan parents are called "Bajan Yankees", a term considered derogatory by some. Generally, Bajans recognise and accept all "children of the island" as Bajans, and refer to each other as such. The biggest communities outside the Afro-Caribbean community are: The Indo-Guyanese, an important part of the economy due to the increase of immigrants from partner country Guyana. There are reports of a growing Indo-Bajans diaspora originating from Guyana and India starting around 1990. Predominantly from southern India, they are growing in size but are smaller than the equivalent communities in Trinidad and Guyana. The Muslim Barbadians of Indian origin are largely of Gujarati ancestry. Many small businesses in Barbados are run and operated by Muslim-Indian Bajans. Euro-Bajans (5% of the population) have settled in Barbados since the 17th century, originating from England, Ireland, Portugal, and Scotland. In 1643, there were 37,200 whites in Barbados (86% of the population). More commonly they are known as "White Bajans". Euro-Bajans introduced folk music, such as Irish music and Highland music, and certain place names, such as "Scotland District", a hilly region in the parish of St. Andrew. Among White Barbadians there exists an underclass known as Redlegs comprising followers of the Duke of Monmouth after his defeat at the Battle of Sedgemoor, as well as the descendants of Irish indentured labourers and prisoners imported to the island. Many additionally moved on to become the earliest settlers of modern-day North and South Carolina in the United States. Today the Redlegs number only around 400. Chinese-Barbadians are a small portion of Barbados's wider Asian population. Chinese food and culture is becoming part of everyday Bajan culture. Lebanese and Syrians form the island's Arab Barbadian community. Jews arrived in Barbados just after the first settlers in 1627. Bridgetown is the home of Nidhe Israel Synagogue, one of the oldest Jewish synagogues in the Americas, dating from 1654, though the current structure was erected in 1833, replacing one ruined by the hurricane of 1831. Tombstones in the neighbouring cemetery date from the 1630s. Now under the care of the Barbados National Trust, the site was deserted in 1929 but was saved and restored by the Jewish community beginning in 1986. In the 17th century, Romani people were sent from the United Kingdom to work as slaves in the plantations in Barbados. Languages English is the official language of Barbados, and is used for communications, administration, and public services all over the island. In its capacity as the official language of the country, the standard of English tends to conform to vocabulary, pronunciations, spellings, and conventions akin to, but not exactly the same as, those of British English. For most people, however, Bajan Creole is the language of everyday life. It does not have a standardised written form, but it is used by over 90% of the population. Religion Christianity is the largest religion in Barbados, with the largest denomination being Anglican (23.9% of the population in 2019). Other Christian denominations with significant followings in Barbados are the Catholic Church (administered by Roman Catholic Diocese of Bridgetown), Pentecostals (19.5%), Jehovah's Witnesses, the Seventh-day Adventist Church and Spiritual Baptists. The Church of England was the official state religion until its legal disestablishment by the Parliament of Barbados following independence. As of 2019, 21% of Barbadians report having no religion, making the non-religious the second largest group after Anglicans. Smaller religions in Barbados include Hinduism, Islam, the Baháʼí Faith, and Judaism. The state is considered secular, guaranteeing freedom of religion or belief to all and featuring only symbolic allusions to a higher power in the preamble to the constitution. Government and politics Barbados has been an independent country since 30 November 1966. It functions as a parliamentary republic modelled on the British Westminster system. The head of state is the President of Barbados – presently Sandra Mason – elected by the Parliament of Barbados for a term of four years, and advised on matters of the Barbadian state by the Prime Minister of Barbados, who is head of government. There are 30 representatives within the House of Assembly, the lower chamber of Parliament. In the Senate, the upper chamber of Parliament, there are 21 senators. The Constitution of Barbados is the supreme law of the country. Legislation is passed by the Parliament of Barbados but does not have the force of law unless the President grants her assent to that law. The right to withhold assent is absolute and cannot be overridden by Parliament. The Attorney General heads the independent judiciary. During the 1990s, at the suggestion of Trinidad and Tobago's Patrick Manning, Barbados attempted a political union with Trinidad and Tobago and Guyana. The project stalled after the then prime minister of Barbados, Lloyd Erskine Sandiford, became ill and his Democratic Labour Party lost the next general election. Barbados continues to share close ties with Trinidad and Tobago and with Guyana, claiming the highest number of Guyanese immigrants after the United States, Canada and the United Kingdom. Barbados is a party to the Rome Statute of the International Criminal Court. Political culture Barbados functions as a two-party system. The dominant political parties are the Democratic Labour Party and the incumbent Barbados Labour Party. Since independence on 30 November 1966, the Democratic Labour Party (DLP) has governed from 1966 to 1976; 1986 to 1994; and from 2008 to 2018; and the Barbados Labour Party (BLP) has governed from 1976 to 1986; 1994 to 2008; and from 2018 to present. Foreign relations Barbados follows a policy of nonalignment and seeks cooperative relations with all friendly states. Barbados is a full and participating member of the Caribbean Community (CARICOM), CARICOM Single Market and Economy (CSME), the Association of Caribbean States (ACS), the Organization of American States (OAS), the Commonwealth of Nations, and the Caribbean Court of Justice (CCJ). In 2005, Barbados replaced the Judicial Committee of the Privy Council with the Caribbean Court of Justice as its final court of appeal. World Trade Organization, European Commission, CARIFORUM Barbados is an original member (1995) of the World Trade Organization (WTO) and participates actively in its work. It grants at least MFN treatment to all its trading partners. European Union relations and cooperation with Barbados are carried out both on a bilateral and a regional basis. Barbados is party to the Cotonou Agreement, through which, , it is linked by an Economic Partnership Agreement with the European Commission. The pact involves the Caribbean Forum (CARIFORUM) subgroup of the African, Caribbean and Pacific Group of States (ACP). CARIFORUM is the only part of the wider ACP-bloc that has concluded the full regional trade-pact with the European Union. There are also ongoing EU-Community of Latin American and Caribbean States (CELAC) and EU-CARIFORUM dialogues. Trade policy has also sought to protect a small number of domestic activities, mostly food production, from foreign competition, while recognising that most domestic needs are best met by imports. The Double Taxation Relief (CARICOM) Treaty 1994 On 6 July 1994, at the Sherbourne Conference Centre, St. Michael, Barbados, representatives of eight countries signed the Double Taxation Relief (CARICOM) Treaties 1994. The countries which were represented were: Antigua and Barbuda, Belize, Grenada, Jamaica, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, and Trinidad and Tobago. On 19 August 1994, a representative of the Government of Guyana signed a similar treaty. Military and law enforcement The Barbados Defence Force has roughly 800 members. Within it, service members aged 14 to 18 years make up the Barbados Cadet Corps. The defence preparations of the island nation are closely tied to defence treaties with the United Kingdom, the United States, and the People's Republic of China. The Barbados Police Service is the sole law enforcement agency on the island of Barbados. Administrative divisions Barbados is divided into 11 parishes: Economy Barbados is the 52nd richest country in the world in terms of GDP (Gross Domestic Product) per capita, has a well-developed mixed economy, and a moderately high standard of living. According to the World Bank, Barbados is one of 83 high income economies in the world. Despite this, a 2012 self-study in conjunction with the Caribbean Development Bank revealed 20% of Barbadians live in poverty, and nearly 10% cannot meet their basic daily food needs. Historically, the economy of Barbados had been dependent on sugarcane cultivation and related activities, but since the late 1970s and early 1980s it has diversified into the manufacturing and tourism sectors. Offshore finance and information services have become important foreign exchange earners. Partly due to the staging of the 2007 Cricket World Cup, the island saw a construction boom, with the development and redevelopment of hotels, office complexes, and homes. This slowed during the 2008 to 2012 world economic crisis and the recession. There was a strong economy between 1999 and 2000 but the economy went into recession in 2001 and 2002 due to slowdowns in tourism, consumer spending and the impact of the 11 September 2001 attacks in the United States and the 7 July 2005 London bombings in the United Kingdom. The economy rebounded in 2003 and has shown growth since 2004 which continued right through to 2008. The economy went into recession again from 2008 to 2013 before showing growth from 2014 to 2017. Then it declined to another recession from 2017 to 2019 during the world economic crisis. There were 23 downgrades by both Standard & Poor's and Moody's in 2016, 2017 and 2018. The economy showed signs of recovery with 3 upgrades from Standard and Poor's and Moody's in 2019. From 1 January to 31 March 2020 the economy had started to grow, but then it experienced another decline due to the COVID-19 economic recession. Traditional trading partners include Canada, the Caribbean Community (especially Trinidad and Tobago), the United Kingdom and the United States. Recent government administrations have continued efforts to reduce unemployment, encourage foreign direct investment, and privatise remaining state-owned enterprises. Unemployment was reduced to 10.7% in 2003. However, it has since increased to 11.9% in second quarter, 2015. The European Union is assisting Barbados with a program of modernisation of the country's International Business and Financial Services Sector. Barbados maintains the third largest stock exchange in the Caribbean region. , officials at the stock exchange were investigating the possibility of augmenting the local exchange with an International Securities Market (ISM) venture. Sovereign default and restructuring By May 2018, Barbados's outstanding debt climbed to , more than 1.7 times the country's GDP. In June 2018 the government defaulted on its sovereign debt when it failed to make a coupon on Eurobonds maturing in 2035. Outstanding bond debt of Barbados reached . In October 2019, Barbados concluded restructuring negotiations with a creditor group including investments funds Eaton Vance Management, Greylock Capital Management, Teachers Advisors and Guyana Bank for Trade and Industry. Creditors will exchange existing bonds for a new debt series maturing in 2029. The new bonds involve a principal "haircut" of approximately 26% and include a clause allowing for deferment of principal and capitalization of interest in the event of a natural disaster. Health The main hospital on the island is the Queen Elizabeth Hospital; however, Barbados has eight polyclinics across five parishes. There are also well-known medical care centres in Barbados such as Bayview Hospital, Sandy Crest Medical Centre and FMH Emergency Medical Clinic. Education The Barbados literacy rate is ranked close to 100%. The mainstream public education system of Barbados is fashioned after the British model. The government of Barbados spends 6.7% of its GDP on education (2008). All young people in the country must attend school until age 16. Barbados has over 70 primary schools and over 20 secondary schools throughout the island. There are a number of private schools, including those offering Montessori and International Baccalaureate education. Student enrolment at these schools represents less than 5% of the total enrolment of the public schools. Certificate-, diploma- and degree-level education in the country is provided by the Barbados Community College, the Samuel Jackman Prescod Institute of Technology, Codrington College, and the Cave Hill campus and Open Campus of the University of the West Indies. Barbados is also home to several overseas medical schools, such as Ross University School of Medicine and the American University of Integrative Sciences, School of Medicine. Educational testing Barbados Secondary School Entrance Examination: Children who are 11 years old on 1 September in the year of the examination are required to write the examination as a means of allocation to secondary school. Caribbean Secondary Education Certificate (CSEC) examinations are usually taken by students after five years of secondary school and mark the end of standard secondary education. The CSEC examinations are equivalent to the Ordinary Level (O-Levels) examinations and are targeted toward students 16 and older. Caribbean Advanced Proficiency Examinations (CAPE) are taken by students who have completed their secondary education and wish to continue their studies. Students who sit for the CAPE usually possess CSEC or an equivalent certification. The CAPE is equivalent to the British Advanced Levels (A-Levels), voluntary qualifications that are intended for university entrance. Culture Barbados is a blend of West African, Portuguese, Creole, Indian and British cultures. Citizens are officially called Barbadians. The term "Bajan" (pronounced BAY-jun) may have come from a localised pronunciation of the word Barbadian, which at times can sound more like "Bar-bajan"; or, more likely, from English bay ("bayling"), Portuguese . The largest carnival-like cultural event that takes place on the island is the Crop Over festival, which was established in 1974. As in many other Caribbean and Latin American countries, Crop Over is an important event for many people on the island, as well as the thousands of tourists that flock to there to participate in the annual events. The festival includes musical competitions and other traditional activities, and features the majority of the island's homegrown calypso and soca music for the year. The male and female Barbadians who harvested the most sugarcane are crowned as the King and Queen of the crop. Crop Over gets under way at the beginning of July and ends with the costumed parade on Kadooment Day, held on the first Monday of August. New calypso/soca music is usually released and played more frequently from the beginning of May to coincide with the start of the festival. Cuisine Bajan cuisine is a mixture of African, Indian, Irish, Creole and British influences. A typical meal consists of a main dish of meat or fish, normally marinated with a mixture of herbs and spices, hot side dishes, and one or more salads. A common Bajan side dish could be pickled cucumber, fish cakes, bake, etc. The meal is usually served with one or more sauces. The national dish of Barbados is cou-cou and flying fish with spicy gravy. Another traditional meal is pudding and souse, a dish of pickled pork with spiced sweet potatoes. A wide variety of seafood and meats are also available. The Mount Gay Rum visitor's centre in Barbados claims to be the world's oldest remaining rum company, with the earliest confirmed deed from 1703. Cockspur Rum and Malibu are also from the island. Barbados is home to the Banks Barbados Brewery, which brews Banks Beer, a pale lager, as well as Banks Amber Ale. Banks also brews Tiger Malt, a non-alcoholic malted beverage. 10 Saints beer is brewed in Speightstown, St. Peter in Barbados and aged for 90 days in Mount Gay 'Special Reserve' Rum casks. It was first brewed in 2009 and is available in certain Caricom nations. Music In 2009, Rihanna was appointed as an Honorary Ambassador of Youth and Culture for Barbados by the late Prime Minister, David Thompson. Sports As in other Caribbean countries of British colonial heritage, cricket is very popular on the island. The West Indies cricket team usually includes several Barbadian players. In addition to several warm-up matches and six "Super Eight" matches, the country hosted the final of the 2007 Cricket World Cup. Barbados has produced many great cricketers including Sir Garfield Sobers, Sir Frank Worrell, Sir Clyde Walcott, Sir Everton Weekes, Gordon Greenidge, Wes Hall, Charlie Griffith, Joel Garner, Desmond Haynes and Malcolm Marshall. In Track and Field Obadele Thompson won a bronze medal in the 100m at the 2000 Summer Olympic Games He's the first to win an Olympic medal. He is also the only Bajan to run sub 10 and sub 20 over 100m and 200m. Ryan Brathwaite won a gold medal in the 110 metres hurdles at the 2009 World Championships in Athletics in Berlin. Rugby is also popular in Barbados. Horse racing takes place at the Historic Garrison Savannah close to Bridgetown. Spectators can pay for admission to the stands, or else can watch races from the public "rail", which encompasses the track. Basketball is an increasingly popular sport, played at school or college. Barbados's national team has shown some unexpected results as in the past it beat many much larger countries. Polo is very popular amongst the rich elite on the island and the "High-Goal" Apes Hill team is based at the St James's Club. It is also played at the private Holders Festival ground. In golf, the Barbados Open, played at Royal Westmoreland Golf Club, was an annual stop on the European Seniors Tour from 2000 to 2009. In December 2006 the WGC-World Cup took place at the country's Sandy Lane resort on the Country Club course, an 18-hole course designed by Tom Fazio. The Barbados Golf Club is another course on the island. It has hosted the Barbados Open on several occasions. Volleyball is also popular and is mainly played indoors. Tennis is gaining popularity and Barbados is home to Darian King, who has achieved a career-high ranking of 106 in May 2017 and has played in the 2016 Summer Olympics and the 2017 US Open. Motorsports also play a role, with Rally Barbados occurring each summer and being listed on the FIA NACAM calendar. Also, the Bushy Park Circuit hosted the Race of Champions and Global RallyCross Championship in 2014. The presence of the trade winds along with favourable swells make the southern tip of the island an ideal location for wave sailing (an extreme form of the sport of windsurfing). Barbados also hosts several international surfing competitions. Netball is also popular with women in Barbados. Several players in the National Football League (NFL) are from Barbados, including Robert Bailey, Roger Farmer, Elvis Joseph, Ramon Harewood and Sam Seale. Transport Although Barbados is about across at its widest point, a car journey from Six Cross Roads in St. Philip (south-east) to North Point in St. Lucy (north-central) can take one and a half hours or longer due to traffic. Barbados has half as many registered cars as citizens. In Barbados, drivers drive on the left side of the road. Barbados is known for its many roundabouts. One famous roundabout is a roundabout located east of Bridgetown, where you will see an emancipation statue commonly associated with a slave named Bussa. Transport on the island is relatively convenient with "route taxis" called "ZRs" (pronounced "Zed-Rs") travelling to most points on the island. These small buses can at times be crowded, as passengers are generally never turned down regardless of the number. They will usually take the more scenic routes to destinations. They generally depart from the capital Bridgetown or from Speightstown in the northern part of the island. Including the ZRs, there are three bus systems running seven days a week (though less frequently on Sundays). There are ZRs, the yellow minibuses and the blue Transport Board buses. A ride on any of them costs . The smaller buses from the two privately owned systems ("ZRs" and "minibuses") can give change; the larger blue buses from the government-operated Barbados Transport Board system cannot, but do give receipts. The Barbados Transport Board buses travel in regular bus routes and scheduled timetables across Barbados. Schoolchildren in school uniform including some Secondary schools ride for free on the government buses and for on the ZRs. Most routes require a connection in Bridgetown. Barbados Transport Board's headquarters are located at Kay's House, Roebuck Street, St. Michael, and the bus depots and terminals are located in the Fairchild Street Bus Terminal in Fairchild Street and the Princess Alice Bus Terminal (which was formerly the Lower Green Bus Terminal in Jubilee Gardens, Bridgetown, St. Michael) in Princess Alice Highway, Bridgetown, St. Michael; the Speightstown Bus Terminal in Speightstown, St. Peter; the Oistins Bus Depot in Oistins, Christ Church; and the Mangrove Bus Depot in Mangrove, St. Philip. In July 2020, the Barbados Transport Board received 33 BYD electric buses which were obtained not only to add to the aging fleet of diesel buses but also to assist the Government in their goal of eliminating the use of fossil fuels by 2030. Some hotels also provide visitors with shuttles to points of interest on the island from outside the hotel lobby. There are several locally owned and operated vehicle rental agencies in Barbados but there are no multi-national companies. The island's lone airport is the Grantley Adams International Airport. It receives daily flights by several major airlines from points around the globe, as well as several smaller regional commercial airlines and charters. The airport serves as the main air-transportation hub for the eastern Caribbean. In the first decade of the 21st century it underwent a upgrade and expansion in February 2003 until completion in August 2005. The island also has a sea port which is the primary port of call for commercial container and cruise traffic. There was also a helicopter shuttle service, which offered air taxi services to a number of sites around the island, mainly on the West Coast tourist belt. Air and maritime traffic was regulated by the Barbados Port Authority.

Belarus

Belarus, officially the Republic of Belarus, is a landlocked country in Eastern Europe. It is bordered by Russia to the east and northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Covering an area of and with a population of 9.2 million, Belarus is the 13th-largest and the 20th-most populous country in Europe. The country has a hemiboreal climate and is administratively divided into six regions. Minsk is the capital and largest city; it is administered separately as a city with special status. Between the medieval period and the 20th century, different states at various times controlled the lands of modern-day Belarus, including Kievan Rus', the Principality of Polotsk, the Grand Duchy of Lithuania, the Polish–Lithuanian Commonwealth, and the Russian Empire. In the aftermath of the Russian Revolution in 1917, different states arose competing for legitimacy amid the Civil War, ultimately ending in the rise of the Byelorussian SSR, which became a founding constituent republic of the Soviet Union in 1922. After the Polish-Soviet War, Belarus lost almost half of its territory to Poland. Much of the borders of Belarus took their modern shape in 1939, when some lands of the Second Polish Republic were reintegrated into it after the Soviet invasion of Poland, and were finalized after World War II. During World War II, military operations devastated Belarus, which lost about a quarter of its population and half of its economic resources. In 1945, the Byelorussian SSR became a founding member of the United Nations, along with the Soviet Union. The republic was home to a widespread and diverse anti-Nazi insurgent movement which dominated politics until well into the 1970s, overseeing Belarus' transformation from an agrarian to industrial economy. The parliament of the republic proclaimed the sovereignty of Belarus on 27 July 1990, and during the dissolution of the Soviet Union, Belarus gained independence on 25 August 1991. Following the adoption of a new constitution in 1994, Alexander Lukashenko was elected Belarus's first president in the country's first and only free election after independence, serving as president ever since. Lukashenko heads a highly centralized authoritarian government. Belarus ranks low in international measurements of freedom of the press and civil liberties. It has continued a number of Soviet-era policies, such as state ownership of large sections of the economy. Belarus is the only European country that continues to use capital punishment. In 2000, Belarus and Russia signed a treaty for greater cooperation, forming the Union State. Belarus is a developing country, ranking 60th on the Human Development Index. The country has been a member of the United Nations since its founding and has joined the CIS, the CSTO, the EAEU, the OSCE, and the Non-Aligned Movement. It has shown no aspirations of joining the European Union but nevertheless maintains a bilateral relationship with the bloc, and also participates in the Baku Initiative. Etymology The name Belarus is closely related with the term Belaya Rus', i.e., White Rus'. There are several claims to the origin of the name White Rus'. An ethno-religious theory suggests that the name used to describe the part of old Ruthenian lands within the Grand Duchy of Lithuania that had been populated mostly by Slavs who had been Christianized early, as opposed to Black Ruthenia, which was predominantly inhabited by pagan Balts. An alternative explanation for the name comments on the white clothing worn by the local Slavic population. A third theory suggests that the old Rus' lands that were not conquered by the Tatars (i.e., Polotsk, Vitebsk and Mogilev) had been referred to as White Rus'. A fourth theory suggests that the color white was associated with the west, and Belarus was the western part of Rus' in the 9th to 13th centuries. The name Rus' is often conflated with its Latin forms Russia and Ruthenia, thus Belarus is often referred to as White Russia or White Ruthenia. The name first appeared in German and Latin medieval literature; the chronicles of Jan of Czarnków mention the imprisonment of Lithuanian grand duke Jogaila and his mother at "" in 1381. The first known use of White Russia to refer to Belarus was in the late-16th century by Englishman Sir Jerome Horsey, who was known for his close contacts with the Russian royal court. During the 17th century, the Russian tsars used the term to describe the lands added from the Grand Duchy of Lithuania. The term Belorussia (, the latter part similar but spelled and stressed differently from Росси́я, Russia) first rose in the days of the Russian Empire, and the Russian Tsar was usually styled "the Tsar of All the Russias", as Russia or the Russian Empire was formed by three parts of Russia—the Great, Little, and White. This asserted that the territories are all Russian and all the peoples are also Russian; in the case of the Belarusians, they were variants of the Russian people. After the Bolshevik Revolution in 1917, the term White Russia caused some confusion, as it was also the name of the military force that opposed the red Bolsheviks. During the period of the Byelorussian SSR, the term Byelorussia was embraced as part of a national consciousness. In western Belarus under Polish control, Byelorussia became commonly used in the regions of Białystok and Grodno during the interwar period. The term Byelorussia (its names in other languages such as English being based on the Russian form) was only used officially until 1991. Officially, the full name of the country is Republic of Belarus (, , ). In Russia, the usage of Belorussia is still very common. In Lithuanian, besides Baltarusija (White Russia), Belarus is also called Gudija. The etymology of the word Gudija is not clear. By one hypothesis the word derives from the Old Prussian name Gudwa, which, in turn, is related to the form Żudwa, which is a distorted version of Sudwa, Sudovia. Sudovia, in its turn, is one of the names of the Yotvingians. Another hypothesis connects the word with the Gothic Kingdom that occupied parts of the territory of modern Belarus and Ukraine in the 4th and 5th centuries. The self-naming of Goths was Gutans and Gytos, which are close to Gudija. Yet another hypothesis is based on the idea that Gudija in Lithuanian means "the other" and may have been used historically by Lithuanians to refer to any people who did not speak Lithuanian. History Early history From 5000 to 2000 BC, the Bandkeramik predominated in what now constitutes Belarus, and the Cimmerians as well as other pastoralists roamed through the area by 1,000 BC. The Zarubintsy culture later became widespread at the beginning of the 1st millennium. In addition, remains from the Dnieper–Donets culture were found in Belarus and parts of Ukraine. The region was first permanently settled by Baltic tribes in the 3rd century. Around the 5th century, the area was taken over by the Slavs. The takeover was partially due to the lack of military coordination of the Balts, but their gradual assimilation into Slavic culture was peaceful in nature. Invaders from Asia, among whom were the Huns and Avars, swept through c. 400–600 AD, but were unable to dislodge the Slavic presence. Kievan Rus' In the 9th century, the territory of modern Belarus became part of Kievan Rus', a vast East Slavic state ruled by the Rurikids. Upon the death of its ruler Yaroslav the Wise in 1054, the state split into independent principalities. The Battle on the Nemiga River in 1067 was one of the more notable events of the period, the date of which is considered the founding date of Minsk. Many early principalities were virtually razed or severely affected by a major Mongol invasion in the 13th century, but the lands of modern-day Belarus avoided the brunt of the invasion and eventually joined the Grand Duchy of Lithuania. There are no sources of military seizure, but the annals affirm the alliance and united foreign policy of Polotsk and Lithuania for decades. Trying to avoid the "Tatar yoke", the Principality of Minsk sought protection from Lithuanian princes further north and in 1242, the Principality of Minsk became a part of the expanding Grand Duchy of Lithuania. Incorporation into the Grand Duchy of Lithuania resulted in an economic, political and ethno-cultural unification of Belarusian lands. Of the principalities held by the duchy, nine of them were settled by a population that would eventually become the Belarusians. During this time, the duchy was involved in several military campaigns, including fighting on the side of Poland against the Teutonic Knights at the Battle of Grunwald in 1410; the joint victory allowed the duchy to control the northwestern borderlands of Eastern Europe. The Muscovites, led by Ivan III of Russia, began military campaigns in 1486 in an attempt to incorporate the former lands of Kievan Rus', including the territories of modern-day Belarus and Ukraine. Polish–Lithuanian Commonwealth On 2 February 1386, the Grand Duchy of Lithuania and the Kingdom of Poland were joined in a personal union through a marriage of their rulers. This union set in motion the developments that eventually resulted in the formation of the Polish–Lithuanian Commonwealth, created in 1569 by the Union of Lublin. The Lithuanian nobles were forced to seek rapprochement with the Poles because of a potential threat from Muscovy. To strengthen their independence within the format of the union, three editions of the Statutes of Lithuania were issued in the second half of the 16th century. The third Article of the Statutes established that all lands of the duchy will be eternally within the Grand Duchy of Lithuania and never enter as a part of other states. The Statutes allowed the right to own land only to noble families of the Grand Duchy of Lithuania. Anyone from outside the duchy gaining rights to a property would actually own it only after swearing allegiance to the Grand Duke of Lithuania (a title dually held by the King of Poland). These articles were aimed to defend the rights of the Lithuanian nobility within the duchy against Polish and other nobles of the Polish–Lithuanian Commonwealth. In the years following the union, the process of gradual Polonization of both Lithuanians and Ruthenians gained steady momentum. In culture and social life, both the Polish language and Catholicism became dominant, and in 1696, Polish replaced Ruthenian as the official language, with Ruthenian being banned from administrative use. However, the Ruthenian peasants continued to speak their native language. Also, the Belarusian Byzantine Catholic Church was formed by the Poles in order to bring Orthodox Christians into the See of Rome. The Belarusian church entered into a full communion with the Latin Church through the Union of Brest in 1595, while keeping its Byzantine liturgy in the Church Slavonic language. The Statutes were initially issued in the Ruthenian language alone and later also in Polish. Around 1840 the Statutes were banned by the Russian tsar following the November Uprising. Ukrainian lands used them until the 1860s. Russian Empire The union between Poland and Lithuania ended in 1795 with the Third Partition of Poland by Imperial Russia, Prussia, and Austria. The Belarusian territories acquired by the Russian Empire under the reign of Catherine II were included into the Belarusian Governorate () in 1796 and held until their occupation by the German Empire during World War I. Under Nicholas I and Alexander III the national cultures were repressed. Policies of Polonization changed by Russification, which included the return to Orthodox Christianity of Belarusian Uniates. Belarusian language was banned in schools while in neighboring Samogitia primary school education with Samogitian literacy was allowed. In a Russification drive in the 1840s, Nicholas I prohibited use of the Belarusian language in public schools, campaigned against Belarusian publications and tried to pressure those who had converted to Catholicism under the Poles to reconvert to the Orthodox faith. In 1863, economic and cultural pressure exploded in a revolt, led by Konstanty Kalinowski (also known as Kastus). After the failed revolt, the Russian government reintroduced the use of Cyrillic to Belarusian in 1864 and no documents in Belarusian were permitted by the Russian government until 1905. During the negotiations of the Treaty of Brest-Litovsk, Belarus first declared independence under German occupation on 25 March 1918, forming the Belarusian People's Republic. Immediately afterwards, the Polish–Soviet War ignited, and the territory of Belarus was divided between Poland and Soviet Russia. The Rada of the Belarusian Democratic Republic exists as a government in exile ever since then; in fact, it is currently the world's longest serving government in exile. Early states and interwar period The Belarusian People's Republic was the first attempt to create an independent Belarusian state under the name "Belarus". Despite significant efforts, the state ceased to exist, primarily because the territory was continually dominated by the German Imperial Army and the Imperial Russian Army in World War I, and then the Bolshevik Red Army. It existed from only 1918 to 1919 but created prerequisites for the formation of a Belarusian state. The choice of name was probably based on the fact that core members of the newly formed government were educated in tsarist universities, with corresponding emphasis on the ideology of West-Russianism. The Republic of Central Lithuania was a short-lived political entity, which was the last attempt to restore Lithuania in the historical confederacy state (it was also supposed to create Lithuania Upper and Lithuania Lower). The republic was created in 1920 following the staged rebellion of soldiers of the 1st Lithuanian–Belarusian Division of the Polish Army under Lucjan Żeligowski. Centered on the historical capital of the Grand Duchy of Lithuania, Vilna (, ), for 18 months the entity served as a buffer state between Poland, upon which it depended, and Lithuania, which claimed the area. After a variety of delays, a disputed election took place on 8 January 1922, and the territory was annexed to Poland. Żeligowski later in his memoir which was published in London in 1943 condemned the annexation of the Republic by Poland, as well as the policy of closing Belarusian schools and general disregard of Marshal Józef Piłsudski's confederation plans by Polish ally. In January 1919, a part of Belarus under Bolshevik Russian control was declared the Socialist Soviet Republic of Byelorussia (SSRB) for just two months, but then merged with the Lithuanian Soviet Socialist Republic (LSSR) to form the Socialist Soviet Republic of Lithuania and Belorussia (SSR LiB), which lost control of its territories by August. The Byelorussian Soviet Socialist Republic (BSSR) was created in July 1920. The contested lands were divided between Poland and the Soviet Union after the war ended in 1921, and the Byelorussian SSR became a founding member of the Union of Soviet Socialist Republics in 1922. In the 1920s and 1930s, Soviet agricultural and economic policies, including collectivization and five-year plans for the national economy, led to famine and political repression. The western part of modern Belarus remained part of the Second Polish Republic. After an early period of liberalization, tensions between increasingly nationalistic Polish government and various increasingly separatist ethnic minorities started to grow, and the Belarusian minority was no exception. The polonization drive was inspired and influenced by the Polish National Democracy, led by Roman Dmowski, who advocated refusing Belarusians and Ukrainians the right for a free national development. A Belarusian organization, the Belarusian Peasants' and Workers' Union, was banned in 1927, and opposition to Polish government was met with state repressions. Nonetheless, compared to the (larger) Ukrainian minority, Belarusians were much less politically aware and active, and thus suffered fewer repressions than the Ukrainians. In 1935, after the death of Piłsudski, a new wave of repressions was released upon the minorities, with many Orthodox churches and Belarusian schools being closed. Use of the Belarusian language was discouraged. Belarusian leadership was sent to Bereza Kartuska prison. World War II In September 1939, the Soviet Union invaded and occupied eastern Poland, following the German invasion of Poland two weeks earlier which marked the beginning of World War II. The territories of Western Belorussia were annexed and incorporated into the Byelorussian SSR. The Soviet-controlled Byelorussian People's Council officially took control of the territories, whose populations consisted of a mixture of Poles, Ukrainians, Belarusians and Jews, on 28 October 1939 in Białystok. Nazi Germany invaded the Soviet Union in 1941. The defense of Brest Fortress was the first major battle of Operation Barbarossa. The Byelorussian SSR was the hardest-hit Soviet republic in World War II; it remained under German occupation until 1944. The German called for the extermination, expulsion, or enslavement of most or all Belarusians for the purpose of providing more living space in the East for Germans. Most of Western Belarus became part of the Reichskommissariat Ostland in 1941, but in 1943 the German authorities allowed local collaborators to set up a client state, the Belarusian Central Council. During World War II, Belarus was home to a variety of guerrilla movements, including Jewish, Polish, and Soviet partisans. Belarusian partisan formations formed a large part of the Soviet partisans, and in the modern day these partisans have formed a core part of the Belarusian national identity, with Belarus continuing to refer to itself as the "partisan republic" since the 1970s. Following the war, many former Soviet partisans entered positions of government, among them Pyotr Masherov and Kirill Mazurov, both of whom were First Secretary of the Communist Party of Byelorussia. Until the late 1970s, the Belarusian government was almost entirely composed of former partisans. Numerous pieces of media have been made about the Belarusian partisans, including the 1985 film Come and See and the works of authors Ales Adamovich and Vasil Bykaŭ. The German occupation in 1941–1944 and war on the Eastern Front devastated Belarus. During that time, 209 out of 290 towns and cities were destroyed, 85% of the republic's industry, and more than one million buildings. After the war, it was estimated that 2.2 million local inhabitants had died and of those some 810,000 were combatants—some foreign. This figure represented a staggering quarter of the prewar population. In the 1990s some raised the estimate even higher, to 2.7 million. The Jewish population of Belarus was devastated during the Holocaust and never recovered. The population of Belarus did not regain its pre-war level until 1971. Belarus was also hit hard economically, losing around half of its economic resources. Post-war After the war, Belarus was among the 51 founding member states of the United Nations Charter and as such it was allowed an additional vote at the UN, on top of the Soviet Union's vote. Vigorous postwar reconstruction promptly followed the end of the war and the Byelorussian SSR became a major center of manufacturing in the western USSR, creating jobs and attracting ethnic Russians. The borders of the Byelorussian SSR and Poland were redrawn, in accord with the 1919-proposed Curzon Line. Joseph Stalin implemented a policy of Sovietization to isolate the Byelorussian SSR from Western influences. This policy involved sending Russians from various parts of the Soviet Union and placing them in key positions in the Byelorussian SSR government. After Stalin's death in 1953, Nikita Khrushchev continued his predecessor's cultural hegemony program, stating, "The sooner we all start speaking Russian, the faster we shall build communism." Soviet Belarusian communist politician Andrei Gromyko, who served as Soviet foreign minister (1957–1985) and as Chairman of the Presidium of the Supreme Soviet (1985–1988), was responsible for many top decisions on Soviet foreign policy until he was replaced by Eduard Shevardnadze. In 1986, the Byelorussian SSR was contaminated with most (70%) of the nuclear fallout from the explosion at the Chernobyl power plant located 16 km beyond the border in the neighboring Ukrainian SSR. By the late 1980s, political liberalization led to a national revival, with the Belarusian Popular Front becoming a major pro-independence force. Independence In March 1990, elections for seats in the Supreme Soviet of the Byelorussian SSR took place. Though the opposition candidates, mostly associated with the pro-independence Belarusian Popular Front, took only 10% of the seats, Belarus declared itself sovereign on 27 July 1990 by issuing the Declaration of State Sovereignty of the Belarusian Soviet Socialist Republic. Mass protests erupted in April 1991 and became known as the 1991 Belarusian strikes. With the support of the Communist Party of Byelorussia, the country's name was changed to the Republic of Belarus on 25 August 1991. Stanislav Shushkevich, the chairman of the Supreme Soviet of Belarus, met with Boris Yeltsin of Russia and Leonid Kravchuk of Ukraine on 8 December 1991 in Białowieża Forest to formally declare the dissolution of the Soviet Union and the formation of the Commonwealth of Independent States. Lukashenko era A national constitution was adopted in March 1994 in which the functions of prime minister were given to the President of Belarus. A two-round election for the presidency on 24 June 1994 and 10 July 1994 catapulted the formerly unknown Alexander Lukashenko into national prominence. He garnered 45% of the vote in the first round and 80% in the second, defeating Vyacheslav Kebich who received 14% of the vote. The elections were the first and only free elections in Belarus after independence. The 2000s saw a number of economic disputes between Belarus and its primary economic partner, Russia. The first one was the 2004 Russia–Belarus energy dispute when Russian energy giant Gazprom ceased the import of gas into Belarus because of price disagreements. The 2007 Russia–Belarus energy dispute centered on accusations by Gazprom that Belarus was siphoning oil off of the Druzhba pipeline that runs through Belarus. Two years later the so-called Milk War, a trade dispute, started when Russia wanted Belarus to recognize the independence of Abkhazia and South Ossetia and through a series of events ended up banning the import of dairy products from Belarus. In 2011, Belarus suffered a severe economic crisis attributed to Lukashenko's government's centralized control of the economy, with inflation reaching 108.7%. Around the same time the 2011 Minsk Metro bombing occurred in which 15 people were killed and 204 were injured. Two suspects, who were arrested within two days, confessed to being the perpetrators and were executed by shooting in 2012. The official version of events as publicised by the Belarusian government was questioned in the unprecedented wording of the UN Security Council statement condemning "the apparent terrorist attack" intimating the possibility that the Belarusian government itself was behind the bombing. Mass protests erupted across the country following the disputed 2020 Belarusian presidential election, in which Lukashenko sought a sixth term in office. Neighbouring countries Poland and Lithuania do not recognize Lukashenko as the legitimate president of Belarus and the Lithuanian government has allotted a residence for main opposition candidate Sviatlana Tsikhanouskaya and other members of the Belarusian opposition in Vilnius. Neither is Lukashenko recognized as the legitimate president of Belarus by the European Union, Canada, the United Kingdom nor the United States. The European Union, Canada, the United Kingdom and the United States have all imposed sanctions against Belarus because of the rigged election and political oppression during the ongoing protests in the country. Further sanctions were imposed in 2022 following the country's role and complicity in the Russian invasion of Ukraine; Russian troops were allowed to stage part of the invasion from Belarusian territory. These include not only corporate offices and individual officers of government but also private individuals who work in the state-owned enterprise industrial sector. Norway and Japan have joined the sanctions regime which aims to isolate Belarus from the international supply chain. Most major Belarusian banks are also under restrictions. Geography Belarus lies between latitudes 51° and 57° N, and longitudes 23° and 33° E. Its extension from north to south is , from west to east is . It is landlocked, relatively flat, and contains large tracts of marshy land. About 40% of Belarus is covered by forests. The country lies within two ecoregions: Sarmatic mixed forests and Central European mixed forests. Many streams and 11,000 lakes are found in Belarus. Three major rivers run through the country: the Neman, the Pripyat, and the Dnieper. The Neman flows westward towards the Baltic sea and the Pripyat flows eastward to the Dnieper; the Dnieper flows southward towards the Black Sea. The highest point is Dzyarzhynskaya Hara (Dzyarzhynsk Hill) at , and the lowest point is on the Neman River at . The average elevation of Belarus is above sea level. The climate features mild to cold winters, with January minimum temperatures ranging from in southwest (Brest) to in northeast (Vitebsk), and cool and moist summers with an average temperature of . Belarus has an average annual rainfall of . The country is in the transitional zone between continental climates and maritime climates. Natural resources include peat deposits, small quantities of oil and natural gas, granite, dolomite (limestone), marl, chalk, sand, gravel, and clay. About 70% of the radiation from neighboring Ukraine's 1986 Chernobyl nuclear disaster entered Belarusian territory, and about a fifth of Belarusian land (principally farmland and forests in the southeastern regions) was affected by radiation fallout. The United Nations and other agencies have aimed to reduce the level of radiation in affected areas, especially through the use of caesium binders and rapeseed cultivation, which are meant to decrease soil levels of caesium-137. Belarus borders five countries: Latvia to the north, Lithuania to the northwest, Poland to the west, Russia to the north and the east, and Ukraine to the south. Treaties in 1995 and 1996 demarcated Belarus's borders with Latvia and Lithuania, and Belarus ratified a 1997 treaty establishing the Belarus-Ukraine border in 2009. Belarus and Lithuania ratified final border demarcation documents in February 2007. Government and politics Belarus, by constitution, is a presidential republic with separation of powers, governed by a president and the National Assembly. However, Belarus has been led by a highly centralized and authoritarian government, and has often been described as "Europe's last dictatorship" and president Alexander Lukashenko as "Europe's last dictator" by some media outlets, politicians and authors. Belarus has been considered an autocracy where power is ultimately concentrated in the hands of the president, elections are not free and judicial independence is weak. The Council of Europe removed Belarus from its observer status since 1997 as a response for election irregularities in the November 1996 constitutional referendum and parliament by-elections. Re-admission of the country into the council is dependent on the completion of benchmarks set by the council, including the improvement of human rights, rule of law, and democracy. The term for each presidency is five years. Under the 1994 constitution, the president could serve for only two terms as president, but a change in the constitution in 2004 eliminated term limits. Lukashenko has been the president of Belarus since 1994. In 1996, Lukashenko called for a controversial vote to extend the presidential term from five to seven years, and as a result the election that was supposed to occur in 1999 was pushed back to 2001. The referendum on the extension was denounced as a "fantastic" fake by the chief electoral officer, Viktar Hanchar, who was removed from the office for official matters only during the campaign. The National Assembly is a bicameral parliament comprising the 110-member House of Representatives (the lower house) and the 64-member Council of the Republic (the upper house). The House of Representatives has the power to appoint the prime minister, make constitutional amendments, call for a vote of confidence on the prime minister, and make suggestions on foreign and domestic policy. The Council of the Republic has the power to select various government officials, conduct an impeachment trial of the president, and accept or reject the bills passed by the House of Representatives. Each chamber has the ability to veto any law passed by local officials if it is contrary to the constitution. The government includes a Council of Ministers, headed by the prime minister and five deputy prime ministers. The members of this council need not be members of the legislature and are appointed by the president. The judiciary comprises the Supreme Court and specialized courts such as the Constitutional Court, which deals with specific issues related to constitutional and business law. The judges of national courts are appointed by the president and confirmed by the Council of the Republic. For criminal cases, the highest court of appeal is the Supreme Court. The Belarusian Constitution forbids the use of special extrajudicial courts. Elections Lukashenko was officially re-elected as president in 2001, in 2006, in 2010, in 2015 and again in 2020, although none of those elections were considered free or fair nor democratic. Neither the pro-Lukashenko parties, such as the Belarusian Social Sporting Party and the Republican Party of Labour and Justice (RPTS), nor the People's Coalition 5 Plus opposition parties, such as the BPF Party and the United Civic Party, won any seats in the 2004 elections. The Organization for Security and Co-operation in Europe (OSCE) ruled that the elections were unfair because opposition candidates were arbitrarily denied registration and the election process was designed to favor the ruling party. In the 2006 presidential election, Lukashenko was opposed by Alaksandar Milinkievič, who represented a coalition of opposition parties, and by Alyaksandr Kazulin of the Social Democrats. Kazulin was detained and beaten by police during protests surrounding the All Belarusian People's Assembly. Lukashenko won the election with 80% of the vote; the Russian Federation and the CIS deemed the vote open and fair while the OSCE and other organizations called the election unfair. After the December completion of the 2010 presidential election, Lukashenko was elected to a fourth straight term with nearly 80% of the vote in elections. The runner-up opposition leader Andrei Sannikov received less than 3% of the vote; independent observers criticized the election as fraudulent. When opposition protesters took to the streets in Minsk, many people, including some presidential candidates, were beaten and arrested by the riot police. Many of the candidates, including Sannikov, were sentenced to prison or house arrest for terms which are mainly and typically over four years. Six months later amid an unprecedented economic crisis, activists utilized social networking to initiate a fresh round of protests characterized by wordless hand-clapping. In the 2012 parliamentary election, 105 of the 110 members elected to the House of Representatives were not affiliated with any political party. The Communist Party of Belarus won 3 seats, and the Belarusian Agrarian Party and RPTS, one each. Most non-partisans represent a wide scope of social organizations such as workers' collectives, public associations, and civil society organizations, similar to the composition of the Soviet legislature. In the 2020 presidential election, Lukashenko won again with official results giving him 80% of the vote, leading to mass protests. The European Union and the United Kingdom did not recognise the result and the EU imposed sanctions. Foreign relations The Byelorussian SSR was one of the two Soviet republics that joined the United Nations along with the Ukrainian SSR as one of the original 51 members in 1945. Belarus and Russia have been close trading partners and diplomatic allies since the breakup of the Soviet Union. Belarus is dependent on Russia for imports of raw materials and for its export market. The Union State, a supranational confederation between Belarus and Russia, was established in a 1996–99 series of treaties that called for monetary union, equal rights, single citizenship, and a common foreign and defense policy. However, the future of the union has been placed in doubt because of Belarus's repeated delays of monetary union, the lack of a referendum date for the draft constitution, and a dispute over the petroleum trade. Belarus was a founding member of the Commonwealth of Independent States (CIS). Belarus has trade agreements with several European Union member states (despite other member states' travel ban on Lukashenko and top officials), including neighboring Latvia, Lithuania, and Poland. Travel bans imposed by the European Union have been lifted in the past in order to allow Lukashenko to attend diplomatic meetings and also to engage his government and opposition groups in dialogue. Bilateral relations with the United States are strained; the United States had not had an ambassador in Minsk since 2007 and Belarus never had an ambassador in Washington since 2008. Diplomatic relations remained tense, and in 2004, the United States passed the Belarus Democracy Act, which authorized funding for anti-government Belarusian NGOs, and prohibited loans to the Belarusian government, except for humanitarian purposes. Relations between China and Belarus are close, with Lukashenko visiting China multiple times during his tenure. Belarus also has strong ties with Syria, considered a key partner in the Middle East. In addition to the CIS, Belarus is a member of the Eurasian Economic Union (previously the Eurasian Economic Community), the Collective Security Treaty Organization, the international Non-Aligned Movement since 1998, and the Organization on Security and Cooperation in Europe (OSCE). As an OSCE member state, Belarus's international commitments are subject to monitoring under the mandate of the U.S. Helsinki Commission. Belarus is included in the European Union's Eastern Partnership program, part of the EU's European Neighbourhood Policy (ENP), which aims to bring the EU and its neighbours closer in economic and geopolitical terms. However, Belarus suspended its participation in the Eastern Partnership program on 28 June 2021, after the EU imposed more sanctions against the country. Military Lieutenant General Viktor Khrenin heads the Ministry of Defence, and Alexander Lukashenko (as president) serves as Commander-in-Chief. The armed forces were formed in 1992 using parts of the former Soviet Armed Forces on the new republic's territory. The transformation of the ex-Soviet forces into the Armed Forces of Belarus, which was completed in 1997, reduced the number of its soldiers by 30,000 and restructured its leadership and military formations. Most of Belarus's service members are conscripts, who serve for 12 months if they have higher education or 18 months if they do not. Demographic decreases in the Belarusians of conscription age have increased the importance of contract soldiers, who numbered 12,000 in 2001. In 2005, about 1.4% of Belarus's gross domestic product was devoted to military expenditure. Belarus has not expressed a desire to join NATO but has participated in the Individual Partnership Program since 1997, and Belarus provided refueling and airspace support for the International Security Assistance Force mission in Afghanistan. Belarus first began to cooperate with NATO upon signing documents to participate in their Partnership for Peace Program in 1995. However, Belarus cannot join NATO because it is a member of the CSTO. Tensions between NATO and Belarus peaked after the March 2006 presidential election in Belarus. Human rights and corruption Amnesty International, and Human Rights Watch have criticized Lukashenko's violations of human rights. Belarus's Democracy Index rating is the lowest in Europe, the country is labelled as "not free" by Freedom House, as "repressed" in the Index of Economic Freedom, and in the Press Freedom Index published by Reporters Without Borders, Belarus is ranked 153th out of 180 countries for 2022. The Belarusian government is also criticized for human rights violations and its persecution of non-governmental organizations, independent journalists, national minorities, and opposition politicians. Lukashenko announced a new law in 2014 that will prohibit kolkhoz workers (around 9% of total work force) from leaving their jobs at will—a change of job and living location will require permission from governors. The law was compared with serfdom by Lukashenko himself. Similar regulations were introduced for the forestry industry in 2012. Belarus is the only European country still using capital punishment, having carried out executions in 2011. LGBT rights in the country are also ranked among the lowest in Europe. The judicial system in Belarus lacks independence and is subject to political interference. Corrupt practices such as bribery often took place during tender processes, and whistleblower protection and national ombudsman are lacking in Belarus's anti-corruption system. On 1 September 2020, the Office of the United Nations High Commissioner for Human Rights declared that its experts received reports of 450 documented cases of torture and ill-treatment of people who were arrested during the protests following the presidential election. The experts also received reports of violence against women and children, including sexual abuse and rape with rubber batons. At least three detainees suffered injuries indicative of sexual violence in Okrestino prison in Minsk or on the way there. The victims were hospitalized with intramuscular bleeding of the rectum, anal fissure and bleeding, and damage to the mucous membrane of the rectum. In an interview from September 2020 Lukashenko claimed that detainees faked their bruises, saying, "Some of the girls there had their butts painted in blue". On 23 May 2021, Belarusian authorities forcibly diverted a Ryanair flight from Athens to Vilnius in order to detain opposition activist and journalist Roman Protasevich along with his girlfriend; in response, the European Union imposed stricter sanctions on Belarus. In May 2021, Lukashenko threatened that he will flood the European Union with migrants and drugs as a response to the sanctions. In July 2021, Belarusian authorities launched a hybrid warfare by human trafficking of migrants to the European Union. Lithuanian authorities and top European officials Ursula von der Leyen, Josep Borrell condemned the usage of migrants as a weapon and suggested that Belarus could be subject to further sanctions. In August 2021, Belarusian officials, wearing uniforms, riot shields and helmets, were recorded on camera near the Belarus–Lithuania border pushing and urging the migrants to cross the European Union border. Following the granting of humanitarian visas to an Olympic athlete Krystsina Tsimanouskaya and her husband, Poland also accused Belarus for organizing a hybrid warfare as the number of migrants crossing the Belarus–Poland border sharply increased multiple times when compared to the 2020 statistics. Illegal migrants numbers also exceeded the previous annual numbers in Latvia. On 2 December 2021, the United States, European Union, United Kingdom and Canada imposed new sanctions on Belarus. Administrative divisions Belarus is divided into six regions called oblasts (; ), which are named after the cities that serve as their administrative centers: Brest, Gomel, Grodno, Mogilev, Minsk, and Vitebsk. Each region has a provincial legislative authority, called a region council (; ), which is elected by its residents, and a provincial executive authority called a region administration (; ), whose chairman is appointed by the president. The regions are further subdivided into 118 raions, commonly translated as districts (; ). Each raion has its own legislative authority, or raion council, (; ) elected by its residents, and an executive authority or raion administration appointed by oblast executive powers. The city of Minsk is split into nine districts and enjoys special status as the nation's capital at the same administration level as the oblasts. It is run by an executive committee and has been granted a charter of self-rule. Local government Local government in Belarus is administered by administrative-territorial units (; ), and occurs on two levels: basic and primary. At the basic level are 118 raions councils and 10 cities of oblast subordination councils, which are supervised by the governments of the oblasts. At the primary level are 14 cities of raion subordination councils, 8 urban-type settlements councils, and 1,151 village councils. The councils are elected by their residents, and have executive committees appointed by their executive committee chairs. The chairs of executive committees for raions and city of oblast subordinations are appointed by the regional executive committees at the level above; the chairs of executive committees for towns of raion subordination, settlements and villages are appointed by their councils, but upon the recommendation of the raion executive committees. In either case, the councils have the power to approve or reject a nonimee for executive committee chair. Settlements without their own local council and executive committee are called territorial units (; ). These territorial units may also be classified as a city of regional or raion subordination, urban-type settlement or rural settlement, but whose government is administered by the council of another primary or basic unit. In October 1995, a presidential decree abolished the local governments of cities of raion subordination and urban-type settlements which served as the administrative center of raions, demoting them from administrative-territorial units to territorial units. As for 2019, the administrative-territorial and territorial units include 115 cities, 85 urban-type settlements, and 23,075 rural settlements. Economy Belarus is a developing country. However, its 60th-place ranking in the United Nations' Human Development Index places it in the category of states with "very high" human development. It is one of the most equal countries in the world, with one of the lowest Gini-coefficient measures of national resource distribution, and it ranks 82nd in GDP per capita. Belarus has trade relations with over 180 countries. The main trading partners are Russia, which accounts for about 45% of Belarusian exports and 55% of imports, and the EU countries, which account for 25% of exports and 20% of imports. In 2019 the share of manufacturing in GDP was 31%, over two-thirds of this amount falls on manufacturing industries. The number of people employed in the industry is 34.7% of the working population. The growth rate is much lower than for the economy as a whole—about 2.2% in 2021. At the time of the dissolution of the Soviet Union in 1991, Belarus was one of the world's most industrially developed states by percentage of GDP as well as the richest CIS member-state. In 2015, 39.3% of Belarusians were employed by state-controlled companies, 57.2% were employed by private companies (in which the government has a 21.1% stake) and 3.5% were employed by foreign companies. The country relies on Russia for various imports, including petroleum. Important agricultural products include potatoes and cattle byproducts, including meat. In 1994, Belarus's main exports included heavy machinery (especially tractors), agricultural products, and energy products. Economically, Belarus involved itself in the CIS, Eurasian Economic Community, and Union with Russia. In the 1990s, however, industrial production plunged due to decreases in imports, investment, and demand for Belarusian products from its trading partners. GDP only began to rise in 1996; the country was the fastest-recovering former Soviet republic in the terms of its economy. In 2006, GDP amounted to US$83.1 billion in purchasing power parity (PPP) dollars (estimate), or about $8,100 per capita. In 2005, GDP increased by 9.9%; the inflation rate averaged 9.5%.Belarus was ranked 80th in the Global Innovation Index in 2023. Since the disintegration of the Soviet Union, under Lukashenko's leadership, Belarus has maintained government control over key industries and eschewed the large-scale privatizations seen in other former Soviet republics. Due to its failure to protect labor rights, including passing laws forbidding unemployment or working outside of state-controlled sectors, Belarus lost its EU Generalized System of Preferences status on 21 June 2007, which raised tariff rates to their prior most favored nation levels. Belarus applied to become a member of the World Trade Organization in 1993. The labor force consists of more than four million people, among whom women hold slightly more jobs than men. In 2005, nearly a quarter of the population was employed by industrial factories. Employment is also high in agriculture, manufacturing sales, trading goods, and education. The unemployment rate, according to government statistics, was 1.5% in 2005. There were 679,000 unemployed Belarusians, two-thirds of whom were women. The unemployment rate has been in decline since 2003, and the overall rate of employment is the highest since statistics were first compiled in 1995. The currency of Belarus is the Belarusian ruble. The currency was introduced in May 1992 to replace the Soviet ruble and it has undergone redenomination twice since then. The first coins of the Republic of Belarus were issued on 27 December 1996. The ruble was reintroduced with new values in 2000 and has been in use ever since. As part of the Union of Russia and Belarus, both states have discussed using a single currency along the same lines as the Euro. This led to a proposal that the Belarusian ruble be discontinued in favor of the Russian ruble (RUB), starting as early as 1 January 2008. The National Bank of Belarus abandoned pegging the Belarusian ruble to the Russian ruble in August 2007. On 23 May 2011, the ruble depreciated 56% against the United States dollar. The depreciation was even steeper on the black market and financial collapse seemed imminent as citizens rushed to exchange their rubles for dollars, euros, durable goods, and canned goods. On 1 June 2011, Belarus requested an economic rescue package from the International Monetary Fund. A new currency, the new Belarusian ruble (ISO 4217 code: BYN) was introduced in July 2016, replacing the Belarusian ruble in a rate of 1:10,000 (10,000 old ruble = 1 new ruble). From 1 July until 31 December 2016, the old and new currencies were in parallel circulation and series 2000 notes and coins could be exchanged for series 2009 from 1 January 2017 to 31 December 2021. This redenomination can be considered an effort to fight the high inflation rate. On 6 October 2022, Lukashenka has banned price increases to combat rise of food prices. In January 2023, Belarus legalized copyright infringement of media and intellectual property created by "unfriendly" foreign nations. The banking system of Belarus consists of two levels: Central Bank (National Bank of the Republic of Belarus) and 25 commercial banks. Demographics According to the 2019 census the population was 9.41 million with ethnic Belarusians constituting 84.9% of Belarus's total population. Minority groups include: Russians (7.5%), Poles (3.1%), and Ukrainians (1.7%). Belarus has a population density of about 50 people per square kilometre (127 per sq mi); 70% of its total population is concentrated in urban areas. Minsk, the nation's capital and largest city, was home to 1,937,900 residents . Gomel, with a population of 481,000, is the second-largest city and serves as the capital of the Gomel Region. Other large cities are Mogilev (365,100), Vitebsk (342,400), Grodno (314,800) and Brest (298,300). Like many other Eastern European countries, Belarus has a negative population growth rate and a negative natural growth rate. In 2007, Belarus's population declined by 0.41% and its fertility rate was 1.22, well below the replacement rate. Its net migration rate is +0.38 per 1,000, indicating that Belarus experiences slightly more immigration than emigration. , 69.9% of Belarus's population is aged 14 to 64; 15.5% is under 14, and 14.6% is 65 or older. Its population is also aging; the median age of 30–34 is estimated to rise to between 60 and 64 in 2050. There are about 0.87 males per female in Belarus. The average life expectancy is 72.15 (66.53 years for men and 78.1 years for women). Over 99% of Belarusians aged 15 and older are literate. Religion and languages According to the census of November 2011, 58.9% of all Belarusians adhered to some kind of religion; out of those, Eastern Orthodoxy made up about 82%: Eastern Orthodox in Belarus are mainly part of the Belarusian Exarchate of the Russian Orthodox Church, though a small Belarusian Autocephalous Orthodox Church also exists. Roman Catholicism is practiced mostly in the western regions, and there are also different denominations of Protestantism. Minorities also practice Greek Catholicism, Judaism, Islam and neo-paganism. Overall, 48.3% of the population is Orthodox Christian, 41.1% is not religious, 7.1% is Roman Catholic and 3.3% follows other religions. Belarus's Catholic minority is concentrated in the western part of the country, especially around Grodno, consisting in a mixture of Belarusians and the country's Polish and Lithuanian minorities. President Lukashenko has stated that Orthodox and Catholic believers are the "two main confessions in our country". Belarus was once a major center of European Jews, with 10% of the population being Jewish. But since the mid-20th century, the number of Jews has been reduced by the Holocaust, deportation, and emigration, so that today it is a very small minority of less than one percent. The Lipka Tatars, numbering over 15,000, are predominantly Muslims. According to Article 16 of the Constitution, Belarus has no official religion. While the freedom of worship is granted in the same article, religious organizations deemed harmful to the government or social order can be prohibited. Belarus's two official languages are Russian and Belarusian; Russian is the most common language spoken at home, used by 70% of the population, while Belarusian, the official first language, is spoken at home by 23%. Minorities also speak Polish, Ukrainian and Eastern Yiddish. Belarusian, although not as widely used as Russian, is the mother tongue of 53.2% of the population, whereas Russian is the mother tongue of only 41.5%. Culture Arts and literature The Belarusian government sponsors annual cultural festivals such as the Slavianski Bazaar in Vitebsk, which showcases Belarusian performers, artists, writers, musicians, and actors. Several state holidays, such as Independence Day and Victory Day, draw big crowds and often include displays such as fireworks and military parades, especially in Vitebsk and Minsk. The government's Ministry of Culture finances events promoting Belarusian arts and culture both inside and outside the country. Belarusian literature began with 11th- to 13th-century religious scripture, such as the 12th-century poetry of Cyril of Turaw. By the 16th century, Polotsk resident Francysk Skaryna translated the Bible into Belarusian. It was published in Prague and Vilnius sometime between 1517 and 1525, making it the first book printed in Belarus or anywhere in Eastern Europe. The modern era of Belarusian literature began in the late 19th century; one prominent writer was Yanka Kupala. Many Belarusian writers of the time, such as Uładzimir Žyłka, Kazimir Svayak, Yakub Kolas, Źmitrok Biadula, and Maksim Haretski, wrote for Nasha Niva, a Belarusian-language paper published that was previously published in Vilnius but now is published in Minsk. After Belarus was incorporated into the Soviet Union, the Soviet government took control of the Republic's cultural affairs. At first, a policy of "Belarusianization" was followed in the newly formed Byelorussian SSR. This policy was reversed in the 1930s, and the majority of prominent Belarusian intellectuals and nationalist advocates were either exiled or killed in Stalinist purges. The free development of literature occurred only in Polish-held territory until Soviet occupation in 1939. Several poets and authors went into exile after the Nazi occupation of Belarus and would not return until the 1960s. The last major revival of Belarusian literature occurred in the 1960s with novels published by Vasil Bykaŭ and Uladzimir Karatkievich. An influential author who devoted his work to awakening the awareness of the catastrophes the country has suffered, was Ales Adamovich. He was named by Svetlana Alexievich, the Belarusian winner of the Nobel Prize in Literature 2015, as "her main teacher, who helped her to find a path of her own". Music in Belarus largely comprises a rich tradition of folk and religious music. The country's folk music traditions can be traced back to the times of the Grand Duchy of Lithuania. In the 19th century, Polish composer Stanisław Moniuszko composed operas and chamber music pieces while living in Minsk. During his stay, he worked with Belarusian poet Vintsent Dunin-Martsinkyevich and created the opera Sialanka (Peasant Woman). At the end of the 19th century, major Belarusian cities formed their own opera and ballet companies. The ballet Nightingale by M. Kroshner was composed during the Soviet era and became the first Belarusian ballet showcased at the National Academic Vialiki Ballet Theatre in Minsk. After the Second World War, music focused on the hardships of the Belarusian people or on those who took up arms in defense of the homeland. During this period, Anatoly Bogatyrev, creator of the opera In Polesye Virgin Forest, served as the "tutor" of Belarusian composers. The National Academic Theatre of Ballet in Minsk was awarded the Benois de la Dance Prize in 1996 as the top ballet company in the world. Rock music has become increasingly popular in recent years, though the Belarusian government has attempted to limit the amount of foreign music aired on the radio in favor of traditional Belarusian music. Since 2004, Belarus has been sending artists to the Eurovision Song Contest. Marc Chagall was born in Liozna (near Vitebsk) in 1887. He spent the World War I years in Soviet Belarus, becoming one of the country's most distinguished artists and a member of the modernist avant-garde and was a founder of the Vitebsk Arts College. Dress The traditional Belarusian dress originates from the Kievan Rus' period. Due to the cool climate, clothes were designed to conserve body heat and were usually made from flax or wool. They were decorated with ornate patterns influenced by the neighboring cultures: Poles, Lithuanians, Latvians, Russians, and other European nations. Each region of Belarus has developed specific design patterns. One ornamental pattern common in early dresses currently decorates the hoist of the Belarusian national flag, adopted in a disputed referendum in 1995. Cuisine Belarusian cuisine consists mainly of vegetables, meat (particularly pork), and bread. Foods are usually either slowly cooked or stewed. Typically, Belarusians eat a light breakfast and two hearty meals later in the day. Wheat and rye bread are consumed in Belarus, but rye is more plentiful because conditions are too harsh for growing wheat. To show hospitality, a host traditionally presents an offering of bread and salt when greeting a guest or visitor. Sport Belarus has competed in the Olympic Games since the 1994 Winter Olympics as an independent nation. Receiving heavy sponsorship from the government, ice hockey is the nation's second most popular sport after football. The national football team has never qualified for a major tournament; however, BATE Borisov has played in the Champions League. The national hockey team finished fourth at the 2002 Salt Lake City Olympics following a memorable upset win over Sweden in the quarterfinals and regularly competes in the World Championships, often making the quarterfinals. Numerous Belarusian players are present in the Kontinental Hockey League in Eurasia, particularly for Belarusian club HC Dinamo Minsk, and several have also played in the National Hockey League in North America. The 2014 IIHF World Championship was hosted in Belarus and the 2021 IIHF World Championship was supposed to be co-hosted in Latvia and Belarus but it was cancelled due to widespread protests and security concerns. The 2021 UEC European Track Championships in cycling was also cancelled because Belarus was not considered a safe host. Darya Domracheva is a leading biathlete whose honours include three gold medals at the 2014 Winter Olympics. Tennis player Victoria Azarenka became the first Belarusian to win a Grand Slam singles title at the Australian Open in 2012. She also won the gold medal in mixed doubles at the 2012 Summer Olympics with Max Mirnyi, who holds ten Grand Slam titles in doubles. Other notable Belarusian sportspeople include cyclist Vasil Kiryienka, who won the 2015 Road World Time Trial Championship, and middle-distance runner Maryna Arzamasava, who won the gold medal in the 800m at the 2015 World Championships in Athletics. Andrei Arlovski, who was born in Babruysk, Byelorussian SSR, is a current UFC fighter and the former UFC heavyweight champion of the world. Belarus is also known for its strong rhythmic gymnasts. Noticeable gymnasts include Inna Zhukova, who earned silver at the 2008 Beijing Olympics, Liubov Charkashyna, who earned bronze at the 2012 London Olympics and Melitina Staniouta, Bronze All-Around Medalist of the 2015 World Championships. The Belarusian senior group earned bronze at the 2012 London Olympics. Telecommunications Country code: .by The state telecom monopoly, Beltelecom, holds the exclusive interconnection with Internet providers outside of Belarus. Beltelecom owns all the backbone channels that linked to the Lattelecom, TEO LT, Tata Communications (former Teleglobe), Synterra, Rostelecom, Transtelekom and MTS ISPs. Beltelecom is the only operator licensed to provide commercial VoIP services in Belarus. World Heritage Sites Belarus has four UNESCO-designated World Heritage Sites: the Mir Castle Complex, the Nesvizh Castle, the Belovezhskaya Pushcha (shared with Poland), and the Struve Geodetic Arc (shared with nine other countries).

Belize

Belize (, ; ) is a country on the north-eastern coast of Central America. It is bordered by Mexico to the north, the Caribbean Sea to the east, and Guatemala to the west and south. It also shares a water boundary with Honduras to the southeast. It has an area of and a population of 441,471 (2022). Its mainland is about long and wide. It is the least populated and least densely populated country in Central America. Its population growth rate of 1.87% per year (2018 estimate) is the second-highest in the region and one of the highest in the Western Hemisphere. Its capital is Belmopan, and its largest city is the namesake city of Belize City. Belize is often thought of as a Caribbean country in Central America because it has a history similar to that of English-speaking Caribbean nations. Belize's institutions and official language reflect its history as a British colony. The Maya civilization spread into the area of Belize between 1500 BC and AD 300 and flourished until about 1200. European contact began in 1492 when Christopher Columbus sailed along the Gulf of Honduras. European exploration was begun by English settlers in 1638. Spain and Britain both laid claim to the land until Britain defeated the Spanish in the Battle of St. George's Caye (1798). In 1840 it became a British colony known as British Honduras, and a Crown colony in 1862. Belize achieved its independence from the United Kingdom on 21 September 1981. It is the only mainland Central American country which is a Commonwealth realm, with King Charles III as its monarch and head of state, represented by a governor-general. Belize has a diverse society composed of many cultures and languages. It is the only Central American country where English is the official language, while Belizean Creole is the most widely spoken dialect. Spanish is the second-most-commonly-spoken language, followed by the Mayan languages, German dialects, and Garifuna. Over half the population is multilingual, due to the diverse linguistic backgrounds of the population. It is known for its September Celebrations, its extensive coral reefs, and punta music. Belize's abundance of terrestrial and marine species and its diversity of ecosystems give it a key place in the globally significant Mesoamerican Biological Corridor. It is considered a Central American and Caribbean nation with strong ties to both the American and Caribbean regions. It is a member of the Caribbean Community (CARICOM), the Community of Latin American and Caribbean States (CELAC), and the Central American Integration System (SICA), the only country to hold full membership in all three regional organizations. Name The earliest known record of the name "Belize" appears in the journal of the Dominican priest Fray José Delgado, dating to 1677. Delgado recorded the names of three major rivers that he crossed while travelling north along the Caribbean coast: Rio Soyte, Rio Kibum, and Rio Balis. The names of these waterways, which correspond to the Sittee River, Sibun River, and Belize River, were provided to Delgado by his translator. It has been proposed that Delgado's "Balis" was actually the Mayan word belix (or beliz), meaning "muddy water", although no such Mayan word actually exists. More recently, it has been proposed that the name comes from the Mayan phrase "bel Itza", meaning "the way to Itza". In the 1820s, the Creole elite of Belize invented the legend that the toponym Belize derived from the Spanish pronunciation of the name of a Scottish buccaneer, Peter Wallace, who established a settlement at the mouth of the Belize River in 1638. There is no proof that buccaneers settled in this area and the very existence of Wallace is considered a myth. Writers and historians have suggested several other possible etymologies, including postulated French and African origins. History Early history The Maya civilization emerged at least three millennia ago in the lowland area of the Yucatán Peninsula and the highlands to the south, in the area of present-day southeastern Mexico, Belize, Guatemala, and western Honduras. Many aspects of this culture persist in the area, despite nearly 500 years of European domination. Prior to about 2500 BC, some hunting and foraging bands settled in small farming villages; they domesticated crops such as corn, beans, squash, and chili peppers. A profusion of languages and subcultures developed within the Maya core culture. Between about 2500 BC and 250 AD, the basic institutions of Maya civilization emerged. Maya civilization The Maya civilization spread across the territory of present-day Belize around 1500BC, and flourished until about 900 AD. The recorded history of the middle and southern regions focuses on Caracol, an urban political centre that may have supported over 140,000 people. North of the Maya Mountains, the most important political centre was Lamanai. In the late Classic Era of Maya civilization (600–1000AD), an estimated 400,000 to 1,000,000 people inhabited the area of present-day Belize. When Spanish explorers arrived in the 16th century, the area of present-day Belize included at least three distinct Maya territories: Chetumal province, which encompassed the area around Corozal Bay Dzuluinicob province, which encompassed the area between the lower New River and the Sibun River, west to Tipu a southern territory controlled by the Manche Ch'ol Maya, encompassing the area between the Monkey River and the Sarstoon River. Early colonial period (1506–1862) Spanish conquistadors explored the land and declared it part of the Spanish Empire, but they failed to settle the territory because of its lack of resources and the hostile tribes of the Yucatán. English pirates sporadically visited the coast of what is now Belize, seeking a sheltered region from which they could attack Spanish ships (see English settlement in Belize) and cut logwood (Haematoxylum campechianum) trees. The first British permanent settlement was founded around 1716, in what became the Belize District, and during the 18th century, established a system using enslaved Africans to cut logwood trees. This yielded a valuable fixing agent for clothing dyes, and was one of the first ways to achieve a fast black before the advent of artificial dyes. The Spanish granted the British settlers the right to occupy the area and cut logwood in exchange for their help suppressing piracy. The British first appointed a superintendent over the Belize area in 1786. Before then the British government had not recognized the settlement as a colony for fear of provoking a Spanish attack. The delay in government oversight allowed the settlers to establish their own laws and forms of government. During this period, a few successful settlers gained control of the local legislature, known as the Public Meeting, as well as of most of the settlement's land and timber. Throughout the 18th century, the Spanish attacked Belize every time war broke out with Britain. The Battle of St. George's Caye was the last of such military engagements, in 1798, between a Spanish fleet and a small force of Baymen and their slaves. From 3 to 5 September, the Spaniards tried to force their way through Montego Caye shoal, but were blocked by defenders. Spain's last attempt occurred on 10 September, when the Baymen repelled the Spanish fleet in a short engagement with no known casualties on either side. The anniversary of the battle has been declared a national holiday in Belize and is celebrated to commemorate the "first Belizeans" and the defence of their territory taken from the Spanish empire. As part of the British Empire (1862–1981) In the early 19th century, the British sought to reform the settlers, threatening to suspend the Public Meeting unless it observed the government's instructions to eliminate slavery outright. After a generation of wrangling, slavery was abolished in the British Empire in 1833. As a result of their enslaved Africans' abilities in the work of mahogany extraction, owners in British Honduras were compensated at £53.69 per enslaved African on average, the highest amount paid in any British territory. This was a form of reparation that was not given to the enslaved Africans at the time, nor since. The end of slavery did little to change the formerly enslaved Africans' working conditions if they stayed at their trade. A series of institutions restricted the ability of emancipated African individuals to buy land, in a debt-peonage system. Former "extra special" mahogany or logwood cutters undergirded the early ascription of the capacities (and consequently the limitations) of people of African descent in the colony. Because a small elite controlled the settlement's land and commerce, formerly enslaved Africans had little choice but to continue to work in timber cutting. In 1836, after the emancipation of Central America from Spanish rule, the British claimed the right to administer the region. In 1862, the United Kingdom formally declared it a British Crown Colony, subordinate to Jamaica, and named it British Honduras. Since 1854, the richest inhabitants elected an assembly of notables by censal vote, which was replaced by a legislative council appointed by the British monarchy. As a colony, Belize began to attract British investors. Among the British firms that dominated the colony in the late 19th century was the Belize Estate and Produce Company, which eventually acquired half of all privately held land and eventually eliminated peonage. Belize Estate's influence accounts in part for the colony's reliance on the mahogany trade throughout the rest of the 19th century and the first half of the 20th century. The Great Depression of the 1930s caused a near-collapse of the colony's economy as British demand for timber plummeted. The effects of widespread unemployment were worsened by a devastating hurricane that struck the colony in 1931. Perceptions of the government's relief effort as inadequate were aggravated by its refusal to legalize labour unions or introduce a minimum wage. Economic conditions improved during World War II, as many Belizean men entered the armed forces or otherwise contributed to the war effort. Following the war, the colony's economy stagnated. Britain's decision to devalue the British Honduras dollar in 1949 worsened economic conditions and led to the creation of the People's Committee, which demanded independence. The People's Committee's successor, the People's United Party (PUP), sought constitutional reforms that expanded voting rights to all adults. The first election under universal suffrage was held in 1954 and was decisively won by the PUP, beginning a three-decade period in which the PUP dominated the country's politics. Pro-independence activist George Cadle Price became PUP's leader in 1956 and the effective head of government in 1961, a post he would hold under various titles until 1984. Progress toward independence was hampered by a Guatemalan claim to sovereignty over Belizean territory. In 1964 Britain granted British Honduras self-government under a new constitution. On 1 June 1973, British Honduras was officially renamed Belize. Independent Belize (since 1981) Belize was granted independence on 21 September 1981. Guatemala refused to recognize the new nation because of its longstanding territorial dispute, claiming that Belize belonged to Guatemala. After independence about 1,500 British troops remained in Belize to deter any possible Guatemalan incursions. With George Cadle Price at the helm, the PUP won all national elections until 1984. In that election, the first national election after independence, the PUP was defeated by the United Democratic Party (UDP). UDP leader Manuel Esquivel replaced Price as prime minister, with Price himself unexpectedly losing his own House seat to a UDP challenger. The PUP under Price returned to power after elections in 1989. The following year the United Kingdom announced that it would end its military involvement in Belize, and the RAF Harrier detachment was withdrawn the same year, having remained stationed in the country continuously since its deployment had become permanent there in 1980. British soldiers were withdrawn in 1994, but the United Kingdom left behind a military training unit to assist with the newly created Belize Defence Force. The UDP regained power in the 1993 national election, and Esquivel became prime minister for a second time. Soon afterwards, Esquivel announced the suspension of a pact reached with Guatemala during Price's tenure, claiming Price had made too many concessions to gain Guatemalan recognition. The pact may have curtailed the 130-year-old border dispute between the two countries. Border tensions continued into the early 2000s, although the two countries cooperated in other areas. In 1996, the Belize Barrier Reef, one of the Western Hemisphere's most pristine ecosystems, was designated as a UNESCO World Heritage Site. The PUP won a landslide victory in the 1998 national elections, and PUP leader Said Musa was sworn in as prime minister. In the 2003 elections the PUP maintained its majority, and Musa continued as prime minister. He pledged to improve conditions in the underdeveloped and largely inaccessible southern part of Belize. In 2005, Belize was the site of unrest caused by discontent with the PUP government, including tax increases in the national budget. On 8 February 2008, Dean Barrow was sworn in as prime minister after his UDP won a landslide victory in general elections. Barrow and the UDP were re-elected in 2012 with a considerably smaller majority. Barrow led the UDP to a third consecutive general election victory in November 2015, increasing the party's number of seats from 17 to 19. He said the election would be his last as party leader and preparations are under way for the party to elect his successor. On 11 November 2020, the People's United Party (PUP), led by Johnny Briceño, defeated the United Democratic Party (UDP) for the first time since 2003, having won 26 seats out of 31 to form the new government of Belize. Briceño took office as Prime Minister on 12 November. Government and politics Belize is a parliamentary constitutional monarchy. The structure of government is based on the British parliamentary system, and the legal system is modelled on the common law of England. The head of state is Charles III, who is the king of Belize. He lives in the United Kingdom, and is represented in Belize by the governor-general. Executive authority is exercised by the cabinet, which advises the governor-general and is led by the prime minister, who is head of government. Cabinet ministers are members of the majority political party in parliament and usually hold elected seats within it concurrent with their cabinet positions. The bicameral National Assembly of Belize comprises a House of Representatives and a Senate. The 31 members of the House are popularly elected to a maximum five-year term and introduce legislation affecting the development of Belize. The governor-general appoints the 12 members of the Senate, with a Senate president selected by the members. The Senate is responsible for debating and approving bills passed by the House. Legislative power is vested in both the government and the Parliament of Belize. Constitutional safeguards include freedom of speech, press, worship, movement, and association. The judiciary is independent of the executive and the legislature. Members of the independent judiciary are appointed. The judicial system includes local magistrates grouped under the Magistrates' Court, which hears less serious cases. The Supreme Court (chief justice) hears murder and similarly serious cases, and the Court of Appeal hears appeals from convicted individuals seeking to have their sentences overturned. Defendants may, under certain circumstances, appeal their cases to the Caribbean Court of Justice. Political culture In 1935, elections were reinstated, but only 1.8 percent of the population was eligible to vote. In 1954, women won the right to vote. Since 1974, the party system in Belize has been dominated by the centre-left People's United Party and the centre-right United Democratic Party, although other small parties took part in all levels of elections in the past. Though none of these small political parties has ever won any significant number of seats or offices, their challenge has been growing over the years. Foreign relations Belize is a full participating member of the United Nations; the Commonwealth of Nations; the Organization of American States (OAS); the Central American Integration System (SICA); the Caribbean Community (CARICOM); the CARICOM Single Market and Economy (CSME); the Association of Caribbean States (ACS); and the Caribbean Court of Justice (CCJ), which currently serves as a final court of appeal for only Barbados, Belize, Guyana and Saint Lucia. In 2001 the Caribbean Community heads of government voted on a measure declaring that the region should work towards replacing the UK's Judicial Committee of the Privy Council as final court of appeal with the Caribbean Court of Justice. It is still in the process of acceding to CARICOM treaties including the trade and single market treaties. Belize is an original member (1995) of the World Trade Organization (WTO), and participates actively in its work. The pact involves the Caribbean Forum (CARIFORUM) subgroup of the Group of African, Caribbean, and Pacific states (ACP). CARIFORUM presently the only part of the wider ACP-bloc that has concluded the full regional trade-pact with the European Union. The British Army Garrison in Belize is used primarily for jungle warfare training, with access to over of jungle terrain. Belize is a party to the Rome Statute of the International Criminal Court. Armed forces The Belize Defence Force (BDF) serves as the country's military. The BDF, with the Belize National Coast Guard and the Immigration Department, is a department of the Ministry of Defence and Immigration. In 1997 the regular army numbered over 900, the reserve army 381, the air wing 45 and the maritime wing 36, amounting to an overall strength of approximately 1,400. In 2005, the maritime wing became part of the Belizean Coast Guard. In 2012, the Belizean government spent about $17 million on the military, constituting 1.08% of the country's gross domestic product (GDP). After Belize achieved independence in 1981 the United Kingdom maintained a deterrent force (British Forces Belize) in the country to protect it from invasion by Guatemala (see Guatemalan claim to Belizean territory). During the 1980s this included a battalion and No. 1417 Flight RAF of Harriers. The main British force left in 1994, three years after Guatemala recognized Belizean independence, but the United Kingdom maintained a training presence via the British Army Training and Support Unit Belize (BATSUB) and 25 Flight AAC until 2011 when the last British Forces left Ladyville Barracks, with the exception of seconded advisers. Administrative divisions Belize is divided into six districts. These districts are further divided into 31 constituencies. Local government in Belize comprises four types of local authorities: city councils, town councils, village councils and community councils. The two city councils (Belize City and Belmopan) and seven town councils cover the urban population of the country, while village and community councils cover the rural population. Guatemalan territorial dispute Throughout Belize's history, Guatemala has claimed sovereignty over all or part of Belizean territory. This claim is occasionally reflected in maps drawn by Guatemala's government, showing Belize as Guatemala's twenty-third department. The Guatemalan territorial claim involves approximately 53% of Belize's mainland, which includes significant portions of four districts: Belize, Cayo, Stann Creek, and Toledo. Roughly 43% of the country's population (≈154,949 Belizeans) reside in this region. , the border dispute with Guatemala remains unresolved and contentious. Guatemala's claim to Belizean territory rests, in part, on Clause VII of the Anglo-Guatemalan Treaty of 1859, which obligated the British to build a road between Belize City and Guatemala. At various times, the issue has required mediation by the United Kingdom, Caribbean Community heads of government, the Organization of American States (OAS), Mexico, and the United States. On 15 April 2018, Guatemala's government held a referendum to determine if the country should take its territorial claim on Belize to the International Court of Justice (ICJ) to settle the long-standing issue. Guatemalans voted 95% yes on the matter. A similar referendum was to be held in Belize on 10 April 2019, but a court ruling led to its postponement. The referendum was held on 8 May 2019, and 55.4% of voters opted to send the matter to the ICJ. Both countries submitted requests to the ICJ (in 2018 and 2019, respectively) and the ICJ ordered Guatemala's initial brief be submitted by December 2020 and Belize's response by 2022. Indigenous land claims Belize backed the United Nations (UN) Declaration on the Rights of Indigenous Peoples in 2007, which established legal land rights to indigenous groups. Other court cases have affirmed these rights like the Supreme Court of Belize's 2013 decision to uphold its ruling in 2010 that acknowledges customary land titles as communal land for indigenous peoples. Another such case is the Caribbean Court of Justice's (CCJ) 2015 order on the Belizean government, which stipulated that the country develop a land registry to classify and exercise traditional governance over Mayan lands. Despite these rulings, Belize has made little progress to support the land rights of indigenous communities; for instance, in the two years after the CCJ's decision, Belize's government failed to launch the Mayan land registry, prompting the group to take action into its own hands. The exact ramifications of these cases need to be examined. , Belize still struggles to recognize indigenous populations and their respective rights. According to the 50-page voluntary national report Belize created on its progress toward the UN's 2030 Sustainable Development Goals, indigenous groups are not factored into the country's indicators whatsoever. Belize's Maya population is only mentioned once in the entirety of the report. Geography Belize is on the Caribbean coast of northern Central America. It shares a border on the north with the Mexican state of Quintana Roo, on the west with the Guatemalan department of Petén, and on the south with the Guatemalan department of Izabal. To the east in the Caribbean Sea, the second-longest barrier reef in the world flanks much of the of predominantly marshy coastline. The area of the country totals , an area slightly larger than El Salvador, Israel, New Jersey, or Wales. The many lagoons along the coasts and in the northern interior reduces the actual land area to . It is the only Central American country with no Pacific coastline. Belize is shaped roughly like a rhombus that extends about north-south and about east-west, with a total land boundary length of . The undulating courses of two rivers, the Hondo and the Sarstoon River, define much of the course of the country's northern and southern boundaries. The western border follows no natural features and runs north–south through lowland forest and highland plateau. The north of Belize consists mostly of flat, swampy coastal plains, in places heavily forested. The flora is highly diverse considering the small geographical area. The south contains the low mountain range of the Maya Mountains. The highest point in Belize is Doyle's Delight at . Belize's rugged geography has also made the country's coastline and jungle attractive to drug smugglers, who use the country as a gateway into Mexico. In 2011, the United States added Belize to the list of nations considered major drug producers or transit countries for narcotics. Environment preservation and biodiversity Belize has a rich variety of wildlife because of its position between North and South America and a wide range of climates and habitats for plant and animal life. Belize's low human population and approximately of undistributed land make for an ideal home for the more than 5,000 species of plants and hundreds of species of animals, including armadillos, snakes, and monkeys. The Cockscomb Basin Wildlife Sanctuary is a nature reserve in south-central Belize established to protect the forests, fauna, and watersheds of an approximately area of the eastern slopes of the Maya Mountains. The reserve was founded in 1990 as the first wilderness sanctuary for the jaguar and is regarded by one author as the premier site for jaguar preservation in the world. Vegetation and flora While over 60% of Belize's land surface is covered by lush forest, some 20% of the country's land is covered by cultivated land (agriculture) and human settlements. Belize had a 2018 Forest Landscape Integrity Index mean score of 6.15/10, ranking it 85th globally out of 172 countries. Savanna, scrubland and wetland constitute the remainder of Belize's land cover. Important mangrove ecosystems are also represented across Belize's landscape. Four terrestrial ecoregions lie within the country's borders – the Petén–Veracruz moist forests, Belizian pine forests, Belizean Coast mangroves, and Belizean Reef mangroves. As a part of the globally significant Mesoamerican Biological Corridor that stretches from southern Mexico to Panama, Belize's biodiversity – both marine and terrestrial – is rich, with abundant flora and fauna. Belize is also a leader in protecting biodiversity and natural resources. According to the World Database on Protected Areas, 37% of Belize's land territory falls under some form of official protection, giving Belize one of the most extensive systems of terrestrial protected areas in the Americas. By contrast, Costa Rica only has 27% of its land territory protected. Around 13.6% of Belize's territorial waters, which contain the Belize Barrier Reef, are also protected. The Belize Barrier Reef is a UNESCO-recognized World Heritage Site and is the second-largest barrier reef in the world, behind Australia's Great Barrier Reef. A remote sensing study conducted by the Water Center for the Humid Tropics of Latin America and the Caribbean (CATHALAC) and NASA, in collaboration with the Forest Department and the Land Information Centre (LIC) of the government of Belize's Ministry of Natural Resources and the Environment (MNRE), and published in August 2010 revealed that Belize's forest cover in early 2010 was approximately 62.7%, down from 75.9% in late 1980. A similar study by Belize Tropical Forest Studies and Conservation International revealed similar trends in terms of Belize's forest cover. Both studies indicate that each year, 0.6% of Belize's forest cover is lost, translating to the clearing of an average of each year. The USAID-supported SERVIR study by CATHALAC, NASA, and the MNRE also showed that Belize's protected areas have been extremely effective in protecting the country's forests. While only some 6.4% of forests inside of legally declared protected areas were cleared between 1980 and 2010, over a quarter of forests outside of protected areas were lost between 1980 and 2010. As a country with a relatively high forest cover and a low deforestation rate, Belize has significant potential for participation in initiatives such as REDD. Significantly, the SERVIR study on Belize's deforestation was also recognized by the Group on Earth Observations (GEO), of which Belize is a member nation. Natural resources and energy Belize is known to have a number of economically important minerals, but none in quantities large enough to warrant mining. These minerals include dolomite, barite (source of barium), bauxite (source of aluminium), cassiterite (source of tin), and gold. In 1990 limestone, used in road construction, was the only mineral resource exploited for domestic or export use. In 2006, the cultivation of newly discovered crude oil in the town of Spanish Lookout has presented new prospects and problems for this developing nation. Access to biocapacity in Belize is much higher than world average. In 2016, Belize had 3.8 global hectares of biocapacity per person within its territory, much more than the world average of 1.6 global hectares per person. In 2016 Belize used 5.4 global hectares of biocapacity per person – their ecological footprint of consumption. This means they use more biocapacity than Belize contains. As a result, Belize is running a biocapacity deficit. Belize Barrier Reef The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly offshore in the north and in the south within the country limits. The Belize Barrier Reef is a section of the Mesoamerican Barrier Reef System, which is continuous from Cancún on the northeast tip of the Yucatán Peninsula through the Riviera Maya up to Honduras making it one of the largest coral reef systems in the world. It is the top tourist destination in Belize, popular for scuba diving and snorkelling, and attracting almost half of its 260,000 visitors. It is also vital to its fishing industry. In 1842 Charles Darwin described it as "the most remarkable reef in the West Indies". The Belize Barrier Reef was declared a World Heritage Site by UNESCO in 1996 due to its vulnerability and the fact that it contains important natural habitats for in-situ conservation of biodiversity. Species The Belize Barrier Reef is home to a large diversity of plants and animals, and is one of the most diverse ecosystems of the world: 70 hard coral species 36 soft coral species 500 species of fish hundreds of invertebrate species With ~90% of the reef still yet to be researched, some estimate that only 10% of all species have been discovered. Conservation Belize became the first country in the world to completely ban bottom trawling in December 2010. In December 2015, Belize banned offshore oil drilling within of the Barrier Reef and all of its seven World Heritage Sites. Despite these protective measures, the reef remains under threat from oceanic pollution as well as uncontrolled tourism, shipping, and fishing. Other threats include hurricanes, along with global warming and the resulting increase in ocean temperatures, which causes coral bleaching. It is claimed by scientists that over 40% of Belize's coral reef has been damaged since 1998. Climate Belize has a tropical climate with pronounced wet and dry seasons, although there are significant variations in weather patterns by region. Temperatures vary according to elevation, proximity to the coast, and the moderating effects of the northeast trade winds off the Caribbean. Average temperatures in the coastal regions range from in January to in July. Temperatures are slightly higher inland, except for the southern highland plateaus, such as the Mountain Pine Ridge, where it is noticeably cooler year round. Overall, the seasons are marked more by differences in humidity and rainfall than in temperature. Average rainfall varies considerably, from in the north and west to over in the extreme south. Seasonal differences in rainfall are greatest in the northern and central regions of the country where, between January and April or May, less than of rainfall per month. The dry season is shorter in the south, normally only lasting from February to April. A shorter, less rainy period, known locally as the "little dry", usually occurs in late July or August, after the onset of the rainy season. Hurricanes have played key—and devastating—roles in Belizean history. In 1931, an unnamed hurricane destroyed over two-thirds of the buildings in Belize City and killed more than 1,000 people. In 1955, Hurricane Janet levelled the northern town of Corozal. Only six years later, Hurricane Hattie struck the central coastal area of the country, with winds in excess of and storm tides. The devastation of Belize City for the second time in thirty years prompted the relocation of the capital some inland to the planned city of Belmopan. In 1978, Hurricane Greta caused more than US$25 million in damage along the southern coast. In 2000, Hurricane Keith, the wettest tropical cyclone in the nation's record, stalled, and hit the nation as a Category 4 storm on 1 October, causing 19 deaths and at least $280 million in damage. Soon after, on 9 October 2001, Hurricane Iris made landfall at Monkey River Town as a Category 4 storm. The storm demolished most of the homes in the village, and destroyed the banana crop. In 2007, Hurricane Dean made landfall as a Category 5 storm only north of the Belize–Mexico border. Dean caused extensive damage in northern Belize. In 2010, Belize was directly affected by the Category 2 Hurricane Richard, which made landfall approximately south-southeast of Belize City at around 00:45 UTC on 25 October 2010. The storm moved inland towards Belmopan, causing estimated damage of BZ$33.8 million ($17.4 million 2010 USD), primarily from damage to crops and housing. The most recent hurricane to make landfall in Belize was Hurricane Lisa in 2022. Economy Belize has a small, mostly private enterprise economy that is based primarily on agriculture, agro-based industry, and merchandising, with tourism and construction recently assuming greater importance. The country is also a producer of industrial minerals, crude oil, and petroleum. , oil production was . In agriculture, sugar, like in colonial times, remains the chief crop, accounting for nearly half of exports, while the banana industry is the largest employer. In 2007 Belize became the world's third largest exporter of papaya. The government of Belize faces important challenges to economic stability. Rapid action to improve tax collection has been promised, but a lack of progress in reining in spending could bring the exchange rate under pressure. The tourist and construction sectors strengthened in early 1999, leading to a preliminary estimate of revived growth at four percent. Infrastructure remains a major economic development challenge; Belize has the region's most expensive electricity. Trade is important and the major trading partners are the United States, Mexico, the United Kingdom, the European Union, and CARICOM. Belize has four commercial bank groups, of which the largest and oldest is Belize Bank. The other three banks are Heritage Bank, Atlantic Bank, and Scotiabank (Belize). A robust complex of credit unions began in the 1940s under the leadership of Marion M. Ganey, S.J. Because of its location on the coast of Central America, Belize is a popular destination for vacationers and for many North American drug traffickers. The Belize currency is pegged to the U.S. dollar and banks in Belize offer non-residents the ability to establish accounts, so drug traffickers and money launderers are attracted to banks in Belize. As a result, the United States Department of State has recently named Belize one of the world's "major money laundering countries". Industrial infrastructure The largest integrated electric utility and the principal distributor in Belize is Belize Electricity Limited. BEL was approximately 70% owned by Fortis Inc., a Canadian investor-owned distribution utility. Fortis took over the management of BEL in 1999, at the invitation of the government of Belize in an attempt to mitigate prior financial problems with the locally managed utility. In addition to its regulated investment in BEL, Fortis owns Belize Electric Company Limited (BECOL), a non-regulated hydroelectric generation business that operates three hydroelectric generating facilities on the Macal River. On 14 June 2011, the government of Belize nationalized the ownership interest of Fortis Inc. in Belize Electricity Ltd. The utility encountered serious financial problems after the country's Public Utilities Commission (PUC) in 2008 "disallowed the recovery of previously incurred fuel and purchased power costs in customer rates and set customer rates at a level that does not allow BEL to earn a fair and reasonable return", Fortis said in a June 2011 statement. BEL appealed this judgement to the Court of Appeal, with a hearing expected in 2012. In May 2011, the Supreme Court of Belize granted BEL's application to prevent the PUC from taking any enforcement actions pending the appeal. The Belize Chamber of Commerce and Industry issued a statement saying the government had acted in haste and expressed concern over the message it sent to investors. In August 2009, the government of Belize nationalized Belize Telemedia Limited (BTL), which now competes directly with Speednet. As a result of the nationalization process, the interconnection agreements are again subject to negotiations. Both BTL and Speednet sell basic telephone services, national and international calls, prepaid services, cellular services via GSM 1900 megahertz (MHz) and 4G LTE respectively, international cellular roaming, fixed wireless, fibre-to-the-home internet service, and national and international data networks. Tourism A combination of natural factors – climate, the Belize Barrier Reef, over 450 offshore Cays (islands), excellent fishing, safe waters for boating, scuba diving, snorkelling and freediving, numerous rivers for rafting, and kayaking, various jungle and wildlife reserves of fauna and flora, for hiking, bird watching, and helicopter touring, as well as many Maya sites – support the thriving tourism and ecotourism industry. Development costs are high, but the government of Belize has made tourism its second development priority after agriculture. In 2012, tourist arrivals totalled 917,869 (with about 584,683 from the United States) and tourist receipts amounted to over $1.3 billion. After COVID-19 struck tourism, Belize became the first country in the Caribbean to allow vaccinated travelers to visit without a COVID-19 test. Demographics Belize's population is estimated to be 441,471 in 2022. Belize's total fertility rate in 2009 was 3.6 children per woman. Its birth rate was 22.9 births/1,000 population (2018 estimate), and the death rate was 4.2 deaths/1,000 population (2018 estimate). A substantial ethnic-demographic shift has been occurring since 1980 when the Creole/Mestizo ratio shifted from 58/38 to currently 26/53, due to many Creoles moving to the US and a rising Mestizo birth rate and migration from El Salvador. Ethnic groups The Maya The Maya are thought to have been in Belize and the Yucatán region since the second millennium BCE. Many died in conflicts between constantly warring tribes or by catching disease from invading Europeans. Three Maya groups now inhabit the country: The Yucatec (who came from Yucatán, Mexico, to escape the savage Caste War of the 1840s), the Mopan (indigenous to Belize but were forced out to Guatemala by the British for raiding settlements; they returned to Belize to evade enslavement by the Guatemalans in the 19th century), and Q'eqchi' (also fled from slavery in Guatemala in the 19th century). The latter groups are chiefly found in the Toledo District. The Maya speak their native languages and Spanish, and are also often fluent in English and Belizean Creole. Creoles Belizean Creoles are primarily mixed-raced descendants of West and Central Africans who were brought to the British Honduras (present-day Belize along the Bay of Honduras) as well as the English and Scottish log cutters, known as the Baymen who trafficked them. Over the years they have also intermarried with Miskito from Nicaragua, Jamaicans and other Caribbean people, Mestizos, Europeans, Garifunas, Mayas, and Chinese and Indians. The latter were brought to Belize as indentured laborers. Majority of Creoles trace their ancestry to several of the aforementioned groups. For all intents and purposes, Creole is an ethnic and linguistic denomination. Some natives, even with blonde hair and blue eyes, may call themselves Creoles. Belize Creole or Kriol developed during the time of slavery, and historically was only spoken by former enslaved Africans. It became an integral part of the Belizean identity, and is now spoken by about 45% of Belizeans. Belizean Creole is derived mainly from English. Its substrate languages are the Native American language Miskito, and the various West African and Bantu languages, native languages of the enslaved Africans. Creoles are found all over Belize, but predominantly in urban areas such as Belize City, coastal towns and villages, and in the Belize River Valley. Garinagu The Garinagu (singular Garifuna), at around 4.5% of the population, are a mix of West/Central African, Arawak, and Island Carib ancestry. Though they were captives removed from their homelands, these people were never documented as slaves. The two prevailing theories are that, in 1635, they were either the survivors of two recorded shipwrecks or somehow took over the ship they came on. Throughout history they have been incorrectly labelled as Black Caribs. When the British took over Saint Vincent and the Grenadines after the Treaty of Paris in 1763, they were opposed by French settlers and their Garinagu allies. The Garinagu eventually surrendered to the British in 1796. The British separated the more African-looking Garifunas from the more indigenous-looking ones. 5,000 Garinagu were exiled from the Grenadine island of Baliceaux. About 2,500 of them survived the voyage to Roatán, an island off the coast of Honduras. The Garifuna language belongs to the Arawakan language family, but has a large number of loanwords from Carib languages and from English. Because Roatán was too small and infertile to support their population, the Garinagu petitioned the Spanish authorities of Honduras to be allowed to settle on the mainland coast. The Spanish employed them as soldiers, and they spread along the Caribbean coast of Central America. The Garinagu settled in Seine Bight, Punta Gorda and Punta Negra, Belize, by way of Honduras as early as 1802. In Belize, 19 November 1832 is the date officially recognized as "Garifuna Settlement Day" in Dangriga. According to one genetic study, their ancestry is on average 76% Sub Saharan African, 20% Arawak/Island Carib and 4% European. Mestizos The Mestizo culture are people of mixed Spanish and Yucatec Maya descent. They originally came to Belize in 1847, to escape the Caste War, which occurred when thousands of Mayas rose against the state in Yucatán and massacred over one-third of the population. The surviving others fled across the borders into British territory. The Mestizos are found everywhere in Belize but most make their homes in the northern districts of Corozal and Orange Walk. Some other Hispanics came from Latin and Central America like El Salvador, Guatemala, Honduras, and Nicaragua. The Mestizos along with Latin Americans are the largest ethnic group in Belize and make up approximately half of the population. The Mestizo towns centre on a main square, and social life focuses on the Hispanic and Catholic Church traditions and customs. Spanish is the main language of most Mestizos and Hispanic descendants, but many speak English and Belizean Creole fluently. Due to the influences of Belizean Creole and English, many Mestizos speak what is known as "Kitchen Spanish". The mixture of Yucatec Mestizo and Yucatec Maya foods like tamales, escabeche, chirmole, relleno, and empanadas came from their Mexican side and corn tortillas were handed down by their Mayan side. Music comes mainly from the marimba, but they also play and sing with the guitar. Dances performed at village fiestas include the Hog-Head, Zapateados, the Mestizada, Paso Doble and many more. German-speaking Mennonites The majority of the Mennonite population comprises so-called Russian Mennonites of German descent who settled in the Russian Empire during the 18th and 19th centuries. Most Russian Mennonites live in Mennonite settlements like Spanish Lookout, Shipyard, Little Belize, and Blue Creek. These Mennonites speak Plautdietsch (a Low German dialect) in everyday life, but use mostly Standard German for reading (the Bible) and writing. The Plautdietsch-speaking Mennonites came mostly from Mexico in the years after 1958 and they are trilingual with proficiency in Spanish. There are also some mainly Pennsylvania Dutch-speaking Old Order Mennonites who came from the United States and Canada in the late 1960s. They live primarily in Upper Barton Creek and associated settlements. These Mennonites attracted people from different Anabaptist backgrounds who formed a new community. They look quite similar to Old Order Amish, but are different from them. Other groups The remaining 5% or so of the population consist of a mix of Indians, Chinese, Whites from the United Kingdom, United States and Canada, and many other foreign groups brought to assist the country's development. During the 1860s, a large influx of East Indians who spent brief periods in Jamaica and American Civil War veterans from Louisiana and other Southern states established Confederate settlements in British Honduras and introduced commercial sugar cane production to the colony, establishing 11 settlements in the interior. The 20th century saw the arrival of more Asian settlers from Mainland China, India, Syria and Lebanon. Said Musa, the son of an immigrant from Palestine, was the Prime Minister of Belize from 1998 to 2008. Central American immigrants from El Salvador, Guatemala, Honduras and Nicaragua and expatriate Americans and Africans also began to settle in the country. 6,000 Mexicans live in Belize. Emigration, immigration, and demographic shifts Creoles and other ethnic groups are emigrating mostly to the United States, but also to the United Kingdom and other developed nations for better opportunities. Based on the latest US Census, the number of Belizeans in the United States is approximately 160,000 (including 70,000 legal residents and naturalized citizens), consisting mainly of Creoles and Garinagu. Because of conflicts in neighbouring Central American nations, Hispanics or Latin American refugees from El Salvador, Guatemala, and Honduras have fled to Belize in significant numbers during the 1980s, and have been significantly adding to Belize's Hispanic population. These two events have been changing the demographics of the nation for the last 30 years. Languages English is the official language of Belize. This stems from the country being a former British colony. Belize is the only country in Central America with English as the official language. Also, English is the primary language of public education, government and most media outlets. About half of Belizeans regardless of ethnicity speak a mostly English-based creole called Belizean Creole (or Kriol in Belizean Creole). Although English is widely used, Belizean Creole is spoken in all situations whether informal, formal, social or interethnic dialogue, even in meetings of the House of Representatives. When a Creole language exists alongside its lexifier language, as is the case in Belize, a continuum forms between the Creole and the lexifier language. It is therefore difficult to substantiate or differentiate the number of Belize Creole speakers compared to English speakers. Creole might best be described as the lingua franca of the nation. Approximately 50% of Belizeans self-identify as Mestizo, Latino, or Hispanic and 50–70% speak Caribbean Spanish as a native language. When Belize was a British colony, Spanish was banned in schools, but today it is widely spoken. "Kitchen Spanish" is an intermediate form of Spanish mixed with Belize Creole, spoken in the northern towns such as Corozal and San Pedro. Over half the population is multilingual. Being a small, multiethnic state, surrounded by Spanish-speaking nations, the economic and social benefits from multilingualism are high. Belize is also home to three Maya languages: Q'eqchi', Mopan (an endangered language), and Yucatec Maya. Approximately 16,100 people speak the Arawakan-based Garifuna language, and 6,900 Mennonites in Belize speak mainly Plautdietsch while a minority of Mennonites speak Pennsylvania Dutch. Largest cities Religion According to the 2010 census, 40.1% of Belizeans are Roman Catholics, 31.8% are Protestants (8.4% Pentecostal; 5.4% Adventist; 4.7% Anglican; 3.7% Mennonite; 3.6% Baptist; 2.9% Methodist; 2.8% Nazarene), 1.7% are Jehovah's Witnesses, 10.3% adhere to other religions (Maya religion, Garifuna religion, Obeah and Myalism, and minorities of the Church of Jesus Christ of Latter-day Saints, Hindus, Buddhists, Muslims, Baháʼís, Rastafarians and other) and 15.5% profess to be irreligious. According to PROLADES, Belize was 64.6% Roman Catholic, 27.8% Protestant, 7.6% Other in 1971. Until the late 1990s, Belize was a Roman Catholic majority country. Catholics formed 57% of the population in 1991, and dropped to 49% in 2000. The percentage of Roman Catholics in the population has been decreasing in the past few decades due to the growth of Protestant churches, other religions and non-religious people. In addition to Catholics, there has always been a large accompanying Protestant minority. It was brought by British, German, and other settlers to the British colony of British Honduras. From the beginning, it was largely Anglican and Mennonite in nature. The Protestant community in Belize experienced a large Pentecostal and Seventh-Day Adventist influx tied to the recent spread of various Evangelical Protestant denominations throughout Latin America. Geographically speaking, German Mennonites live mostly in the rural districts of Cayo and Orange Walk. The Greek Orthodox Church has a presence in Santa Elena. The Association of Religion Data Archives estimates there were 7,776 Baháʼís in Belize in 2005, or 2.5% of the national population. Their estimates suggest this is the highest proportion of Baháʼís in any country. Their data also states that the Baháʼí Faith is the second most common religion in Belize, following Christianity. Hinduism is followed by most Indian immigrants. Sikhs were the first Indian immigrants to Belize (not counting indentured workers), and the former Chief Justice of Belize George Singh was the son of a Sikh immigrant, there was also a Sikh cabinet minister. Muslims claim that there have been Muslims in Belize since the 16th century having been brought over from Africa as slaves, but there are no sources for that claim. The Muslim population of today started in the 1980s. Muslims numbered 243 in 2000 and 577 in 2010 according to the official statistics. and comprise 0.16 percent of the population. A mosque is at the Islamic Mission of Belize (IMB), also known as the Muslim Community of Belize. Another mosque, Masjid Al-Falah, officially opened in 2008 in Belize City. Health Belize has a high prevalence of communicable diseases such as respiratory diseases and intestinal illnesses. Education A number of kindergartens, secondary, and tertiary schools in Belize provide quality education for students—mostly funded by the government. Belize has about a dozen tertiary level institutions, the most prominent of which is the University of Belize, which evolved out of the University College of Belize founded in 1986. Before that St. John's College, founded in 1877, dominated the tertiary education field. The Open Campus of the University of the West Indies has a site in Belize. It also has campuses in Barbados, Trinidad, and Jamaica. The government of Belize contributes financially to the UWI. Education in Belize is compulsory between the ages of 6 and 14 years. , the literacy rate in Belize was estimated at 79.7%, one of the lowest in the Western Hemisphere. The educational policy is currently following the "Education Sector Strategy 2011–2016", which sets three objectives for the years to come: Improving access, quality, and governance of the education system by providing technical and vocational education and training. Crime Belize has moderate rates of violent crime. The majority of violence in Belize stems from gang activity, which includes trafficking of drugs and persons, protecting drug smuggling routes, and securing territory for drug dealing. In 2019, 102 murders were recorded in Belize, giving the country a homicide rate of 24 murders per 100,000 inhabitants, lower than the neighbouring countries of Mexico and Honduras, but higher than Guatemala and El Salvador. Belize District (containing Belize City) had the most murders by far compared to all the other districts. In 2019, 58% of the murders occurred in the Belize District. The violence in Belize City (especially the southern part of the city) is largely due to gang warfare. In 2015, there were 40 reported cases of rape, 214 robberies, 742 burglaries, and 1027 cases of theft. The Belize Police Department has implemented many protective measures in hopes of decreasing the high number of crimes. These measures include adding more patrols to "hot spots" in Belize City, obtaining more resources to deal with the predicament, creating the "Do the Right Thing for Youths at Risk" program, creating the Crime Information Hotline, creating the Yabra Citizen Development Committee, an organization that helps youth, and other initiatives. In 2011, the government established a truce among many major gangs, lowering the murder rate. Social structure Belize's social structure is marked by enduring differences in the distribution of wealth, power, and prestige. Because of the small size of Belize's population and the intimate scale of social relations, the social distance between the rich and the poor, while significant, is nowhere as vast as in other Caribbean and Central American societies, such as Jamaica and El Salvador. Belize lacks the violent class and racial conflict that has figured so prominently in the social life of its Central American neighbours. Political and economic power remain vested in the hands of the local elite. The sizeable middle group is composed of peoples of different ethnic backgrounds. This middle group does not constitute a unified social class, but rather a number of middle-class and working-class groups, loosely oriented around shared dispositions toward education, cultural respectability, and possibilities for upward social mobility. These beliefs, and the social practices they engender, help distinguish the middle group from the grass roots majority of the Belizean people. Women In 2021, the World Economic Forum ranked Belize 90th out of 156 countries in its Global Gender Gap Report. Of all the countries in Latin America and the Caribbean, Belize ranked fourth from last. It ranked higher in the categories of "economic participation and opportunity" and "health and survival", but very low in "political empowerment". In 2019, the UN gave Belize a Gender Inequality Index score of 0.415, ranking it 97th out of 162 countries. , 49.9% of women in Belize participate in the workforce, compared to 80.6% of men. 11.1% of the seats in Belize's National Assembly are filled by women. Culture In Belizean folklore, there are the legends of Lang Bobi Suzi, La Llorona, La Sucia, Tata Duende, Anansi, Xtabay, Sisimite and the cadejo. Most of the public holidays in Belize are traditional Commonwealth and Christian holidays, although some are specific to Belizean culture such as Garifuna Settlement Day and Heroes and Benefactors' Day, formerly Baron Bliss Day. In addition, the month of September is considered a special time of national celebration called September Celebrations with a whole month of activities on a special events calendar. Besides Independence Day and St. George's Caye Day, Belizeans also celebrate Carnival during September, which typically includes several events spread across multiple days, with the main event being the Carnival Road March, usually held the Saturday before 10 September. In some areas of Belize, it is celebrated at the traditional time before Lent (in February). Cuisine Belizean cuisine is an amalgamation of all ethnicities in the nation, and their respectively wide variety of foods. It might best be described as both similar to Mexican/Central American cuisine and Jamaican/Anglo-Caribbean cuisine but very different from these areas as well, with Belizean touches and innovation which have been handed down by generations. All immigrant communities add to the diversity of Belizean food, including the Indian and Chinese communities. The Belizean diet can be both very modern and traditional. There are no rules. Breakfast typically consists of bread, flour tortillas, or fry jacks (deep fried dough pieces) that are often homemade. Fry jacks are eaten with various cheeses, "fry" beans, various forms of eggs or cereal, along with powdered milk, coffee, or tea. Tacos made from corn or flour tortillas and meat pies can also be consumed for a hearty breakfast from a street vendor. Midday meals are the main meals for Belizeans, usually called "dinner". They vary, from foods such as rice and beans with or without coconut milk, tamales, "panades" (fried maize shells with beans or fish), meat pies, escabeche (onion soup), chimole (soup), caldo, stewed chicken, and garnaches (fried tortillas with beans, cheese, and sauce) to various constituted dinners featuring some type of rice and beans, meat and salad, or coleslaw. Fried "fry" chicken is another common course. In rural areas, meals are typically simpler than in cities. The Maya use maize, beans, or squash for most meals, and the Garifuna are fond of seafood, cassava (particularly made into cassava bread or ereba), and vegetables. The nation abounds with restaurants and fast food establishments that are fairly affordable. Local fruits are quite common, but raw vegetables from the markets less so. Mealtime is a communion for families and schools and some businesses close at midday for lunch, reopening later in the afternoon. Music In recent years, Latin music, including reggaeton and banda, has experienced a surge in popularity in Belize, alongside the traditional genres of punta and brukdown. This growing trend reflects the influence of neighboring Latin American countries and the cultural connections that exist within the region. The rise in popularity of Latin music in Belize demonstrates the vibrant and diverse musical landscape of the country, showcasing the ability of music to transcend borders and bring people together. Punta is distinctly Caribbean, and is sometimes said to be ready for international popularization like similarly descended styles (reggae, calypso, merengue). Brukdown is a modern style of Belizean music related to calypso. It evolved out of the music and dance of loggers, especially a form called buru. Reggae, dance hall, and soca imported from Trinidad, Jamaica, and the rest of the West Indies, rap, hip-hop, heavy metal, and rock music from the United States, are also popular among the youth of Belize. Sports The major sports in Belize are football, basketball, volleyball and cycling, with smaller followings of boat racing, athletics, softball, cricket and rugby. Fishing is also popular in coastal areas of Belize. The Cross Country Cycling Classic, also known as the "cross country" race or the Holy Saturday Cross Country Cycling Classic, is considered one of the most important Belize sports events. This one-day sports event is meant for amateur cyclists but has also gained worldwide popularity. The history of Cross Country Cycling Classic in Belize dates back to the period when Monrad Metzgen picked up the idea from a small village on the Northern Highway (now Phillip Goldson Highway). The people from this village used to cover long distances on their bicycles to attend the weekly game of cricket. He improvised on this observation by creating a sporting event on the difficult terrain of the Western Highway, which was then poorly built. Another major annual sporting event in Belize is the La Ruta Maya Belize River Challenge, a 4-day canoe marathon held each year in March. The race runs from San Ignacio to Belize City, a distance of . On Easter day, citizens of Dangriga participate in a yearly fishing tournament. First, second, and third prize are awarded based on a scoring combination of size, species, and number. The tournament is broadcast over local radio stations, and prize money is awarded to the winners. The Belize national basketball team is the only national team that has achieved major victories internationally. The team won the 1998 CARICOM Men's Basketball Championship, held at the Civic Centre in Belize City, and subsequently participated in the 1999 Centrobasquet Tournament in Havana. The national team finished seventh of eight teams after winning only 1 game despite playing close all the way. In a return engagement at the 2000 CARICOM championship in Barbados, Belize placed fourth. Shortly thereafter, Belize moved to the Central American region and won the Central American Games championship in 2001. The team has failed to duplicate this success, most recently finishing with a 2–4 record in the 2006 COCABA championship. The team finished second in the 2009 COCABA tournament in Cancun, Mexico where it went 3–0 in group play. Belize won its opening match in the Centrobasquet Tournament, 2010, defeating Trinidad and Tobago, but lost badly to Mexico in a rematch of the COCABA final. A tough win over Cuba set Belize in position to advance, but they fell to Puerto Rico in their final match and failed to qualify. Simone Biles, the winner of four gold medals in the 2016 Rio Summer Olympics is a dual citizen of the United States and of Belize, which she considers her second home. Biles is of Belizean-American descent. National symbols The national flower of Belize is the black orchid (Prosthechea cochleata, also known as Encyclia cochleata). The national tree is the mahogany tree (Swietenia macrophylla), which inspired the national motto Sub Umbra Floreo, which means "Under the shade I flourish". The national ground-dwelling animal is the Baird's tapir and the national bird is the keel-billed toucan (Ramphastos sulphuratus).

Bermuda

Bermuda (; historically known as the Bermudas or Somers Isles) is a British Overseas Territory in the North Atlantic Ocean. The closest land outside the territory is in the American state of North Carolina, about to the west-northwest. Bermuda is an archipelago consisting of 181 islands, although the most significant islands are connected by bridges and appear to form one landmass. It has a land area of . Bermuda has a sub-tropical climate, with mild winters and warm summers. Its climate also exhibits oceanic features similar to other coastal areas in the Northern Hemisphere with warm, moist air from the ocean ensuring relatively high humidity and stabilising temperatures. Bermuda lies in Hurricane Alley and thus is prone to severe weather; however, it receives some protection from a coral reef and its position at the north of the belt, which limits the direction and severity of approaching storms. Bermuda is named after Spanish explorer Juan de Bermúdez, who discovered the archipelago in 1505. The islands have been permanently inhabited since 1612 when an English settlement was established at St. George's. Forming part of British America, Bermuda was governed under royal charter by the Somers Isles Company until 1684, when it became a crown colony. The first African slaves were taken to Bermuda in 1616, but a full plantation economy did not develop and the slave trade largely ceased by the end of the 17th century. The economy instead became maritime-focused, with the colony serving as a base for merchants, privateers and the Royal Navy, giving its name to the Bermuda rig and Bermuda sloop. It became an imperial fortress, the most important British naval and military base in the western hemisphere with vast funds lavished on its Royal Naval Dockyard and military defences. Tourism has been a significant contributor to Bermuda's economy since the 19th century and after World War II, the territory became a prominent offshore financial centre and tax haven. Divided into nine parishes, Bermuda is a self-governing parliamentary democracy with a bicameral parliament located in the capital Hamilton. The House of Assembly dates from 1620, making it one of the world's oldest legislatures. The premier is the head of government and is formally appointed by the governor, who is nominated by the British government as the representative of the King. The United Kingdom is responsible for foreign affairs and defence. An independence referendum was held in 1995 with a large majority voting against independence. As of 2019, Bermuda had a population of around 64,000 people, making it the second-most populous of the British Overseas Territories. Black Bermudians, primarily descended from African slaves, make up around 50% of the population, while White Bermudians, primarily of British, Irish and Portuguese descent, make up 30% of the population. There are smaller groups from other races or identifying as mixed race and about 30% of the population is not Bermudian by birth. Bermuda has a distinct dialect of English and has historically had strong ties with other English-speaking countries in the Americas, including the United States, Canada, and the Commonwealth Caribbean. It is an associate member of the Caribbean Community. Etymology Bermuda is named after the Spanish sailor Juan de Bermúdez, who discovered the islands in 1505, while sailing for Spain from a provisioning voyage to Hispaniola in the ship La Garça. History Discovery Bermuda was discovered in the early 1500s by Spanish explorer Juan de Bermúdez. Bermuda had no indigenous population when it was discovered, nor during initial British settlement a century later. It was mentioned in Legatio Babylonica, published in 1511 by historian Pedro Mártir de Anglería, and was included on Spanish charts of that year. Both Spanish and Portuguese ships used the islands as a replenishment spot to take on fresh meat and water. Shipwrecked Portuguese mariners are now thought to have been responsible for the 1543 inscription on Portuguese Rock, previously called Spanish Rock. Legends arose of spirits and devils, now thought to have stemmed from the calls of raucous birds (most likely the Bermuda petrel, or cahow) and loud nocturnal noises from wild hogs. With its frequent storm-racked conditions and dangerous reefs, the archipelago became known as the "Isle of Devils". Neither Spain nor Portugal attempted to settle it. Settlement by the English For the next century, the island was frequently visited but not settled. The English began to focus on the New World, initially settling in Virginia, starting British colonization in North America, establishing a colony at Jamestown, Virginia in 1607. Two years later, a flotilla of seven ships left England with several hundred settlers, food, and supplies to relieve the Jamestown colony. However, the flotilla was broken up by a storm and the flagship, the Sea Venture, drove onto Bermuda's reef to prevent her sinking, resulting in the survival of all her passengers and crew. The settlers were unwilling to move on, having now heard about the true conditions in Jamestown from the sailors, and made multiple attempts to rebel and stay in Bermuda. They argued that they had a right to stay and establish their own government. The new settlement became a prison labour camp, and built two ships, the Deliverance and the Patience. In 1612, the English began settlement of the archipelago, officially named Virgineola, with arrival of the ship the Plough. New London (renamed St. George's Town) was settled that year and designated as the colony's first capital. It is the oldest continuously inhabited English town in the New World. In 1615, the colony, which had been renamed the Somers Isles in commemoration of Sir George Somers, was passed on to the Somers Isles Company. As Bermudians settled the Carolina Colony and contributed to establishing other English colonies in the Americas, several other locations were named after the archipelago. During this period the first slaves were held and trafficked to the islands. These were a mixture of native Africans who were trafficked to the Americas via the African slave trade and Native Americans who were enslaved from the Thirteen Colonies. The archipelago's limited land area and resources led to the creation of what may be the earliest conservation laws of the New World. In 1616 and 1620 acts were passed banning the hunting of certain birds and young tortoises. Civil War In 1649, the English Civil War was taking place and King Charles I was beheaded in Whitehall, London. The conflict spilled over into Bermuda, where most of the colonists developed a strong sense of devotion to the Crown. The royalists ousted the Somers Isles Company's Governor and elected John Trimingham as their leader (see Governor of Bermuda). Bermuda's civil war was ended by militias, and dissenters were pushed to settle The Bahamas under William Sayle. The rebellious royalist colonies of Bermuda, Virginia, Barbados and Antigua, were the subjects of an Act of the Rump Parliament of England. The royalist colonies were also threatened with invasion. The Government of Bermuda eventually reached an agreement with the Parliament of England which retained the status quo in Bermuda. Later 17th century In the 17th century, the Somers Isles Company suppressed shipbuilding, as it needed Bermudians to farm in order to generate income from the land. The Virginia colony, however, far surpassed Bermuda in quality and quantity of tobacco produced. Bermudians began to turn to maritime trades relatively early in the 17th century, but the Somers Isles Company used all its authority to suppress turning away from agriculture. This interference led to islanders demanding, and receiving, revocation of the company's charter in 1684, and the company was dissolved. Bermudians rapidly abandoned agriculture for shipbuilding, replanting farmland with the native juniper trees (Juniperus bermudiana, called Bermuda cedar). Establishing effective control over the Turks Islands, Bermudians deforested their landscape to begin the salt trade. It became the world's largest and remained the cornerstone of Bermuda's economy for the next century. Bermudians also vigorously pursued whaling, privateering, and the merchant trade Some islanders, especially in St David's, still trace their ancestry to Native Americans, and many more are ignorant of having such ancestry. Hundreds of Native Americans were shipped to Bermuda. The best-known examples were the Algonquian peoples such as (Pequots, Wampanoags, Podunks, Nipmucks, Narragansetts,...), who were exiled from the New England colonies and sold into slavery in the seventeenth century, notably in the aftermaths of the Pequot War and King Philip's War, but some are believed to have been brought from as far away as Mexico. The American War of Independence Bermuda's ambivalence towards the American rebellion changed in September 1774, when the Continental Congress resolved to ban trade with Great Britain, Ireland, and the West Indies after 10 September 1775. Such an embargo would mean the collapse of their inter-colonial commerce, famine and civil unrest. Lacking political channels with Great Britain, the Tucker Family met in May 1775 with eight other parishioners and resolved to send delegates to the Continental Congress in July, aiming for an exemption from the ban. Henry Tucker noted a clause in the ban which allowed the exchange of American goods for military supplies. The clause was confirmed by Benjamin Franklin when Tucker met with the Pennsylvania Committee of Safety. Independently, others confirmed this business arrangement with Peyton Randolph, the Charlestown Committee of Safety, and George Washington. Three American boats, operating from Charlestown, Philadelphia and Newport, sailed to Bermuda, and on 14 August 1775, 100 barrels of gunpowder were taken from the Bermudian magazine while Governor George James Bruere slept, and loaded onto these boats. As a consequence, on 2 October the Continental Congress exempted Bermuda from their trade ban, and Bermuda acquired a reputation for disloyalty. Later that year, the British Parliament passed the Prohibitory Act to prohibit trade with the American rebelling colonies and sent HMS Scorpion to keep watch over the island. The island's forts were stripped of cannons. Yet, wartime trade of contraband continued along well-established family connections. With 120 boats by 1775, Bermuda continued to trade with St. Eustatius until 1781 and provided salt to North American ports. In June 1776, HMS Nautilus secured the island, followed by in September. Yet, the two British captains seemed more intent on capturing prize money, causing a severe food shortage on the island until the departure of Nautilus in October. After France's entry into the war in 1778, Henry Clinton refortified the island under the command of Major William Sutherland. As a result, 91 French and American ships were captured in the winter of 1778–1779, bringing the population once again to the brink of starvation. Bermudian trade was severely hampered by the combined efforts of the Royal Navy, the British garrison and loyalist privateers, such that famine struck the island in 1779. Upon the death of George Bruere in 1780, the governorship passed to his son, George Jr., an active loyalist. Under his leadership, smuggling was stopped, and the Bermudian colonial government was populated with like-minded loyalists. Even Henry Tucker abandoned trading with the United States, because of the presence of many privateers. The Bermuda Gazette, Bermuda's first newspaper, began publishing in 1784. The editor, Joseph Stockdale, had been given financial incentive to move to Bermuda with his family and establish the newspaper. He also provided other printing services and operated Bermuda's first local postal service. The Bermuda Gazette was sold by subscription and delivered to subscribers, with Stockdale's employee also delivering mail for a fee. 19th century After the American Revolution, the Royal Navy began improving the harbours on the Bermudas. In 1811, work began on the large Royal Naval Dockyard on Ireland Island, which was to serve as the islands' principal naval base guarding the western Atlantic Ocean shipping lanes. To guard the dockyard, the British Army built the Bermuda Garrison, and heavily fortified the archipelago. During the War of 1812 between Britain and the United States, the British attacks on Washington, D.C., and the Chesapeake were planned and launched from Bermuda, where the headquarters of the Royal Navy's North American Station had recently been moved from Halifax, Nova Scotia. In 1816, James Arnold, the son of Benedict Arnold, fortified Bermuda's Royal Naval Dockyard against possible US attacks. Today, the National Museum of Bermuda, which incorporates Bermuda's Maritime Museum, occupies the Keep of the Royal Naval Dockyard. Due to its proximity to the southeastern US coast, Bermuda was frequently used during the American Civil War as a stopping point base for the Confederate States' blockade runners on their runs to and from the Southern states, and England, to evade Union naval vessels on blockade patrol. The blockade runners were then able to transport essential war goods from England and deliver valuable cotton back to England. The old Globe Hotel in St. George's, which was a centre of intrigue for Confederate agents, is preserved as a public museum. Anglo-Boer War During the Anglo-Boer War (1899–1902), 5,000 Boer prisoners of war were housed on five islands of Bermuda. They were located according to their views of the war. "Bitterenders" (Afrikaans: Bittereinders), who refused to pledge allegiance to the British Crown, were interned on Darrell's Island and closely guarded. Other islands such as Morgan's Island held 884 men, including 27 officers; Tucker's Island held 809 Boer prisoners, Burt's Island 607, and Port's Island held 35. Hinson's Island housed underage prisoners. The camp cemetery is on Long Island. The New York Times reported an attempted mutiny by Boer prisoners of war en route to Bermuda and that martial law was enacted on Darrell's Island. The most famous escapee was the Boer prisoner of war Captain Fritz Joubert Duquesne, who was serving a life sentence for "conspiracy against the British government and on (the charge of) espionage". On the night of 25 June 1902, Duquesne slipped out of his tent, worked his way over a barbed-wire fence, swam past patrol boats and bright spotlights, through storm-swept waters, using the distant Gibbs Hill Lighthouse for navigation until he arrived ashore on the main island. He settled in the U.S. and later became a spy for Germany in both World Wars. In 1942, Col. Duquesne was arrested by the FBI for leading the Duquesne Spy Ring, which to this day remains the largest espionage case in the history of the United States. 20th and 21st centuries In the early 20th century Bermuda became a popular destination for American, Canadian and British tourists arriving by sea. The US Smoot–Hawley Tariff Act of 1930, which enacted protectionist trade tariffs on goods imported into the US, led to the demise of Bermuda's once-thriving agricultural export trade to America and encouraged development of tourism as an alternative source of income. The island was one of the centres for illegal alcohol smuggling during the era of Prohibition in the United States (1920–1933). A rail line was constructed in Bermuda in the 1920s, opening in 1931 as the Bermuda Railway, which was abandoned in 1948. The right of way is now the Bermuda Railway Trail. In 1930, after several failed attempts, a Stinson Detroiter seaplane flew to Bermuda from New York City: It was the first aeroplane ever to reach the islands. In 1936, Deutsche Luft Hansa began to experiment with seaplane flights from Berlin via the Azores with continuation flights to New York City. In 1937, Imperial Airways and Pan American Airways began operating scheduled flying boat airline services from New York and Baltimore to Darrell's Island, Bermuda. In World War II, the Hamilton Princess Hotel became a censorship centre. All mail, radio and telegraphic traffic bound for Europe, the US and the Far East was intercepted and analysed by 1,200 censors, of British Imperial Censorship, part of British Security Coordination (BSC), before being routed to their destination. With BSC working closely with the FBI, the censors were responsible for the discovery and arrest of a number of Axis spies operating in the US, including the Joe K ring. In 1948, a regularly scheduled commercial airline service began to operate, using land-based aeroplanes landing at Kindley Field (now L.F. Wade International Airport), helping tourism to reach a peak in the 1960s and 1970s. By the end of the 1970s, however, international business had supplanted tourism as the dominant sector of Bermuda's economy. The Royal Naval Dockyard and its attendant military garrison remained important to Bermuda's economy until the mid-20th century. In addition to considerable building work, the armed forces needed to source food and other materials from local vendors. Beginning in World War II, US military installations were also located in Bermuda, including a naval air station, and submarine base. The American military presence lasted until 1995. Universal adult suffrage and development of a two-party political system took place in the 1960s. Universal suffrage was adopted as part of Bermuda's Constitution in 1967; voting had previously been dependent on a certain level of property ownership. On 10 March 1973, the governor of Bermuda, Richard Sharples, was assassinated by local Black Power militants during a period of civil unrest. Some moves were made towards possible independence for the islands, however, this was decisively rejected in a referendum in 1995. At the 2020 Summer Olympics, Bermuda became the smallest overseas territory to earn a gold medal, as Flora Duffy won Bermuda's first ever Olympic gold medal in the women's triathlon. Geography Bermuda is a group of low-forming volcanoes in the Atlantic Ocean, in the west of the Sargasso Sea, roughly east-southeast of Cape Hatteras on the Outer Banks of North Carolina, United States which is the nearest landmass. Its next nearest neighbour is Cape Sable Island, Nova Scotia Canada which is north of Bermuda. It is also located north-northeast of Havana, Cuba, north of the British Virgin Islands, and north of San Juan, Puerto Rico. The territory consists of 181 islands, with a total area of . The largest island is Main Island (also called Bermuda). Eight larger and populated islands are connected by bridges. The territory's tallest peak is Town Hill on Main Island at 79 metres tall (260′). The territory's coastline is . Bermuda gives its name to the Bermuda Triangle, a region of sea in which, according to legend, a number of aircraft and boats have disappeared under unexplained or mysterious circumstances. Main sights Bermuda's pink sand beaches and clear, cerulean blue ocean waters are popular with tourists. Many of Bermuda's hotels are located along the south shore of the island. In addition to its beaches, there are a number of sightseeing attractions. Historic St. George's is a designated World Heritage Site. Scuba divers can explore numerous wrecks and coral reefs in relatively shallow water (typically in depth), with virtually unlimited visibility. Many nearby reefs are readily accessible from shore by snorkellers, especially at Church Bay. Bermuda's most popular visitor attraction is the Royal Naval Dockyard, which includes the National Museum of Bermuda. Other attractions include the Bermuda Aquarium, Museum and Zoo, Bermuda Underwater Exploration Institute, the Botanical Gardens and Masterworks Museum of Bermuda Art, lighthouses, and the Crystal Caves with stalactites and underground saltwater pools. Non-residents are prohibited from driving cars on the island. Public transport and taxis are available or visitors can rent scooters for use as private transport. Geology Bermuda consists of over 150 limestone islands, but especially five main islands, along the southern margin of the Bermuda Platform, one of three topographic highs found on the Bermuda Pedestal. This Bermuda Pedestal sits atop the Bermuda Rise, a mid-basin swell surrounded by abyssal plains. The Bermuda Pedestal is one of four topographic highs aligned roughly from North-East to South-West. The others, all submerged, being Bowditch Seamount to the North-East, and Challenger Bank and Argus Bank to the South-West. Initial uplift of this rise occurred in the Middle to Late Eocene and concluded by the Late Oligocene, when it subsided below sea level. The volcanic rocks associated with this rise are tholeiitic lavas and intrusive lamprophyre sheets, which form a volcanic basement, on average, below the island carbonate surface. The limestones of Bermuda consist of biocalcarenites with minor conglomerates. The portion of Bermuda above sea level consists of rocks deposited by aeolian processes, with a karst terrain. These eolianites are actually the type locality, and formed during interglaciations (i.e., the upper levels of the limestone cap, formed primarily by calcium-secreting algae, was broken down into sand by wave action during interglaciation when the seamount was submerged, and during glaciation, when the top of the seamount was above sea level, that sand was blown into dunes and fused together into a limestone sandstone), and are laced by red paleosols, also referred to as geosols or terra rossas, indicative of Saharan atmospheric dust and forming during glacial stages. The stratigraphic column starts with the Walsingham Formation, overlain by the Castle Harbour Geosol, the Lower and Upper Town Hill Formations separated by the Harbour Road Geosol, the Ord Road Geosol, the Belmont Formation, the Shore Hills Geosol, the Rocky Bay Formation, and the Southampton Formation. The older eolianite ridges (older Bermuda) are more rounded and subdued compared to the outer coastline (Younger Bermuda). Thus, post deposition morphology includes chemical erosion, with inshore water bodies demonstrating that much of Bermuda is partially drowned Pleistocene karst. The Walsingham Formation is a clear example, constituting the cave district around Castle Harbour. The Upper Town Hill Formation forms the core of the Main Island, and prominent hills such as Town Hill, Knapton Hill, and St. David's Lighthouse, while the highest hills, Gibbs Hill Lighthouse, are due to the Southampton Formation. Bermuda has two major aquifers, the Langton Aquifer located within the Southampton, Rocky Bay and Belmont Formations, and the Brighton Aquifer located within the Town Hill Formation. Four freshwater lenses occur in Bermuda, with the Central Lens being the largest on Main Island, containing an area of and a thickness greater than . Climate Bermuda has a tropical rainforest climate (Köppen climate classification: Af), bordering very closely on a humid subtropical climate (Köppen climate classification: Cfa). It is also an oceanic climate, common to many oceanic islands and to the western coasts of continents in the Northern Hemisphere (resulting in a more moderate climate on the western coast of Europe than on the eastern coast of North America), characterised by high relative humidity that moderates temperature, ensuring generally mild winters and summers. Bermuda is warmed by the nearby Gulf Stream. The islands may experience modestly cooler temperatures in January, February, and March [average ]. There has never been snow, a frost or freeze on record in Bermuda. The hardiness zone is 11b/12a. In other words, the coldest that the annual minimum temperature may be expected to be is around .) This is very high for such a latitude and is a half-zone higher than the Florida Keys. Summertime heat index in Bermuda can be high, although mid-August temperatures rarely exceed . The highest recorded temperature was in August 1989. The average annual temperature of the Atlantic Ocean around Bermuda is , from in February to in August. Bermuda is in the hurricane belt. Along the Gulf Stream, it is often directly in the path of hurricanes recurving in the westerlies, although they usually begin to weaken as they approach Bermuda, whose small size means that direct landfalls of hurricanes are rare. Hurricane Emily was the first to do so in three decades when it struck Bermuda without warning in 1987. The most recent hurricanes to cause significant damage to Bermuda were category 2 Hurricane Gonzalo on 18 October 2014 and category 3 Hurricane Nicole on 14 October 2016, both of which struck the island directly. Category 2 Hurricane Paulette directly hit the island in 2020. Before that, Hurricane Fabian on 5 September 2003 was the last major hurricane to hit Bermuda directly, with wind speeds of over , category 3). With no rivers or freshwater lakes, the only source of fresh water is rainfall, which is collected on roofs and catchments (or drawn from underground lenses) and stored in tanks. Each dwelling usually has at least one of these tanks forming part of its foundation. The law requires that each household collect rainwater that is piped down from the roof of each house. Average monthly rainfall is highest in October, at over , and lowest in April and May. Access to biocapacity in Bermuda is much lower than world average. In 2016, Bermuda had 0.14 global hectares of biocapacity per person within its territory, far lower than the world average of 1.6 global hectares per person. In 2016 Bermuda used 7.5 global hectares of biocapacity per person — their ecological footprint of consumption. This means they use much more biocapacity than Bermuda contains. As a result, Bermuda runs a biocapacity deficit. Flora and fauna When discovered, Bermuda was uninhabited by humans and mostly dominated by forests of Bermuda cedar, with mangrove marshes along its shores. Only 165 of the island's current 1,000 vascular plant species are considered native; fifteen of those, including the eponymous cedar, are endemic. The subtropical climate of Bermuda allowed settlers to introduce many species of trees and plants to the island. Today, many types of palm trees, fruit trees, and bananas grow on Bermuda, though the cultivated coconut palms are considered non-native and may be removed. The country contains the Bermuda subtropical conifer forests terrestrial ecoregion. The only indigenous mammals of Bermuda are five species of bat, all of which are also found in the eastern United States: Lasionycteris noctivagans, Lasiurus borealis, Lasiurus cinereus, Lasiurus seminolus and Perimyotis subflavus. Other commonly known fauna of Bermuda include its national bird, the Bermuda petrel or cahow, which was rediscovered in 1951 after having been thought extinct since the 1620s. The cahow is important as an example of a Lazarus species, hence the government has a programme to protect it, including restoration of its habitat areas. Another well-known species includes the white-tailed tropicbird, locally known as the Longtail. These birds come inland to breed around February to March and are Bermudians' first sign of incoming spring. The Bermuda rock lizard (or Bermuda rock skink) was long thought to have been the only indigenous land vertebrate of Bermuda, discounting the marine turtles that lay their eggs on its beaches. However, scientists have recently discovered through genetic DNA studies that a species of turtle, the diamondback terrapin, previously thought to have been introduced to the archipelago, actually pre-dated the arrival of humans. Demographics Bermuda's 2016 Census put its population at 63,779 and, with an area of , it has a calculated population density of 1,201 people/km2 (3,111/mi2). As of July 2018, the population is estimated to be 71,176. The racial makeup of Bermuda was 52% Black, 31% White, 9% multiracial, 4% Asian, and 4% other races, these numbers being based on self-identification recorded by the 2016 census. The majority of those who answered "Black" may have any mixture of black, white or other ancestry. Native-born Bermudians made up 70% of the population, compared to 30% non-natives. The island experienced large-scale immigration over the 20th century, especially after World War II. About 64% of the population identified themselves with Bermudian ancestry in 2010, which was an increase from the 51% who did so in the 2000 census. Those identifying with British ancestry dropped by 1% to 11% (although those born in the United Kingdom remain the largest non-native group at 3,942 people). The number of people born in Canada declined by 13%. Those who reported West Indian ancestry were 13%. The number of people born in the West Indies actually increased by 538. A significant segment of the population is of Portuguese ancestry (25%), the result of immigration over the past 160 years, of whom 79% have residency status. In June 2018, Premier Edward David Burt announced that 4 November 2019 "will be declared a public holiday to mark the 170th anniversary of the arrival of the first Portuguese immigrants in Bermuda" due to the significant impact that Portuguese immigration has had on the territory. Those first immigrants arrived from Madeira aboard the vessel the Golden Rule on 4 November 1849. There are also several thousand expatriate workers, principally from the United Kingdom, Canada, the West Indies, South Africa, and the United States, who reside in Bermuda. They are primarily engaged in specialised professions such as accounting, finance, and insurance. Others are employed in various trades, such as hotels, restaurants, construction, and landscaping services. Despite the high cost of living, the high salaries offer expatriates several benefits by moving to Bermuda and working for a period of time. Of the total workforce of 38,947 people in 2005, government employment figures stated that 11,223 (29%) were non-Bermudians. Languages The predominant language in Bermuda is Bermudian English. British English spellings and conventions are used in print media and formal written communications. Portuguese is also spoken by migrants from the Azores, Madeira, and the Cape Verde Islands and their descendants. Religion Christianity is the largest religion on Bermuda. Various Protestant denominations are dominant at 46.2% (including Anglican 15.8%; African Methodist Episcopal 8.6%; Seventh-day Adventist 6.7%; Pentecostal 3.5%; Methodist 2.7%; Presbyterian 2.0%; Church of God 1.6%; Baptist 1.2%; Salvation Army 1.1%; Brethren 1.0%; other Protestant 2.0%). Roman Catholics form 14.5%, Jehovah's Witnesses 1.3%, and other Christians 9.1%. The balance of the population are Muslim 1%, other 3.9%, none 17.8%, or unspecified 6.2% (2010 est.). The Anglican Church of Bermuda, an Anglican Communion diocese separate from the Church of England, operates the oldest non-Catholic parish in the New World, St. Peter's Church. Catholics are served by a single Latin diocese, the Diocese of Hamilton in Bermuda. Politics Bermuda is an Overseas Territory of the United Kingdom, and the Government of the United Kingdom is the sovereign government. Executive authority in Bermuda is vested in the British monarch (currently Charles III) and is exercised on his behalf by the governor of Bermuda. The governor is appointed by the king on the advice of the British Government. Since December 2020, the governor is Rena Lalgie; she was sworn in on 14 December 2020. There is also a deputy governor (currently Alison Crocket). Defence and foreign affairs are the responsibility of the United Kingdom, which also retains responsibility to ensure good government and must approve any changes to the Constitution of Bermuda. Bermuda is Britain's oldest overseas territory. Although the UK Parliament retains ultimate legislative authority over the territory, in 1620, a Royal Proclamation granted Bermuda limited self-governance, delegating to the House of Assembly of the Parliament of Bermuda the internal legislation of the colony. The Parliament of Bermuda is the fifth oldest legislature in the world, behind the Parliament of England, the Tynwald of the Isle of Man, the Althing of Iceland, and the Sejm of Poland. The Constitution of Bermuda came into force in 1968 and has been amended several times since then. The head of government is the premier of Bermuda; a cabinet is nominated by the premier and appointed officially by the governor. The legislative branch consists of a bicameral parliament modelled on the Westminster system. The Senate is the upper house, consisting of 11 members appointed by the governor on the advice of the premier and the leader of the opposition. The House of Assembly, or lower house, has 36 members, elected by the eligible voting populace in secret ballot to represent geographically defined constituencies. Elections for the Parliament of Bermuda must be called at no more than five-year intervals. The most recent took place on 1 October 2020. Following this election, the Progressive Labour Party held onto power, with Edward David Burt sworn in as Premier for the second time. There are few accredited diplomats in Bermuda. The United States maintains the largest diplomatic mission in Bermuda, comprising both the United States Consulate and the US Customs and Border Protection Services at the L.F. Wade International Airport. The United States is Bermuda's largest trading partner (providing over 71% of total imports, 85% of tourist visitors, and an estimated $163 billion of US capital in the Bermuda insurance/re-insurance industry). According to the 2016 Bermuda census 5.6% of Bermuda residents were born in the US, representing over 18% of all foreign-born people. Nationality and citizenship Historically, English (later British) colonials shared the same citizenship as those born within that part of the sovereign territory of the Kingdom of England (including the Principality of Wales) that lay within the Island of Britain (although the Magna Carta had effectively created English citizenship, citizens were still termed 'subjects of the King of England' or 'English subjects'. With the 1707 union of the Kingdoms of England and Scotland, this was replaced with 'British Subject', which encompassed citizens throughout the sovereign territory of the British Government, including its colonies, though not the British protectorates). With no representation at the sovereign or national level of government, British colonials were therefore not consulted, or required to give their consent, to a series of Acts passed by the Parliament of the United Kingdom between 1968 and 1982, which were to limit their rights and ultimately change their citizenship. When several colonies had been elevated before the Second World War to Dominion status, collectively forming the old British Commonwealth (as distinct from the United Kingdom and its dependent colonies), their citizens remained British Subjects, and in theory, any British Subject born anywhere in the World had the same basic right to enter, reside, and work in the United Kingdom as a British Subject born in the United Kingdom whose parents were also both British Subjects born in the United Kingdom (although many governmental policies and practices acted to thwart the free exercise of these rights by various groups of colonials, including Greek Cypriots). When the Dominions and an increasing number of colonies began choosing complete independence from the United Kingdom after the Second World War, the Commonwealth was transformed into a community of independent nations, or Commonwealth Realms, each recognising the British monarch as its own head of state (creating separate monarchies with the same person occupying all of the separate Thrones; the exception being republican India). 'British Subject' was replaced by the British Nationality Act 1948 with 'Citizen of the United Kingdom and Colonies' for the residents of the United Kingdom and its colonies, as well as for the Crown Dependencies. However, as it was desired to retain free movement for all Commonwealth Citizens throughout the Commonwealth, 'British Subject' was retained as a blanket nationality shared by Citizens of the United Kingdom and Colonies (the 'British realm') as well as the citizens of the various other Commonwealth realms. The inflow of people of colour to the United Kingdom in the 1940s and 1950s from both the remaining colonies and newly independent Commonwealth nations was responded to with a backlash that led to the passing of the Commonwealth Immigrants Act 1962, which restricted the rights of Commonwealth nationals to enter, reside and work in the United Kingdom. This Act also allowed certain colonials (primarily ethnic-Indians in African colonies) to retain Citizenship of the United Kingdom and Colonies if their colonies became independent, which was intended as a measure to ensure these people did not become stateless if they were denied the citizenship of their newly independent nation. Many ethnic-Indians from former African colonies (notably Kenya) subsequently relocated to the United Kingdom, in response to which the Commonwealth Immigrants Act 1968 was rapidly passed, stripping all British Subjects (including Citizens of the United Kingdom and Colonies) who were not born in the United Kingdom, and who did not have a Citizen of the United Kingdom and Colonies parent or grandparent born in the United Kingdom or some other qualification (such as existing residence status), of the rights to freely enter, reside and work in the United Kingdom. Although the 1968 Act was intended primarily to bar immigration of specific British passport holders from Commonwealth countries in Africa, it amended the wording of the Commonwealth Immigrants Act 1962 in such a way as to apply to all Citizens of the United Kingdom and Colonies who were not specifically excepted, including most colonials. This was followed by the Immigration Act 1971, which effectively divided Citizens of the United Kingdom and Colonies into two types, although their citizenship remained the same: Patrials, who were those from (or with a specified qualifying connection to) the United Kingdom itself, who retained the rights of free entry, abode, and work in the United Kingdom; and those born in the colonies (or in foreign countries to British Colonial parents), from whom those rights were denied. The British Nationality Act 1981, which entered into force on 1 January 1983, abolished British Subject status, and stripped colonials of their full British Citizenship of the United Kingdom and Colonies, replacing it with British Dependent Territories Citizenship, which entailed no right of abode or to work anywhere. This left Bermudians and most other erstwhile British colonials as British nationals without the rights of British citizenship. The exceptions were the Gibraltarians (permitted to retain British Citizenship in order to also retain Citizenship of the European Union) and the Falkland Islanders, who were permitted to retain the same new British Citizenship that became the default citizenship for those from the United Kingdom and the Crown Dependencies. The stripping of birthright citizenship from Bermudians by the British Government in 1968 and 1971, and the change of their citizenship in 1983, violated the rights granted them by Royal Charters at the founding of the colony. Bermuda (fully The Somers Isles or Islands of Bermuda) had been settled by the London Company (which had been in occupation of the archipelago since the 1609 wreck of the Sea Venture) in 1612, when it received its Third Royal Charter from King James I, amending the boundaries of the First Colony of Virginia far enough across the Atlantic to include Bermuda. The citizenship rights guaranteed to settlers by King James I in the original Royal Charter of 10 April 1606, thereby applied to Bermudians: These rights were confirmed in the Royal Charter granted to the London Company's spin-off, the Company of the City of London for the Plantacion of The Somers Isles, in 1615 on Bermuda being separated from Virginia: Bermuda is not the only territory whose citizenship rights were laid down in a Royal Charter. In regards to St. Helena, Lord Beaumont of Whitley in the House of Lords debate on the British Overseas Territories Bill on 10 July 2001, stated: Some Conservative Party backbenchers stated that it was the unpublished intention of the Conservative British Government to return to a single citizenship for the United Kingdom and all of the remaining territories once Hong Kong had been handed over to China. Whether this was so will never be known as by 1997 the Labour Party was in Government. The Labour Party had declared prior to the election that the colonies had been ill-treated by the British Nationality Act 1981, and it had made a pledge to return to a single citizenship for the United Kingdom and the remaining territories part of its election manifesto. Other matters took precedence, however, and this commitment was not acted upon during Labour's first term in Government. The House of Lords, in which many former colonial Governors sat (including former Governor of Bermuda Lord Waddington), lost patience and tabled and passed its own bill, then handed it down to the House of Commons to confirm in 2001. As a result, the British Dependent Territories were renamed the British Overseas Territories in 2002 (the term 'dependent territory' had caused much ire in the former colonies, especially well-heeled and self-reliant Bermuda, as it implied not only that British Dependent Territories Citizens were 'other than British', but that their relationship to Britain and to 'real British people' was both inferior and parasitic). At the same time, although Labour had promised a return to a single citizenship for the United Kingdom, Crown dependencies, and all remaining territories, British Dependent Territories Citizenship, renamed British Overseas Territories Citizenship, remained the default citizenship for the territories, other than the Falkland Islands and Gibraltar (for which British Citizenship is still the default citizenship). The bars to residence and work in the United Kingdom that had been raised against holders of British Dependent Territories Citizenship by The British Nationality Act 1981 were, however, removed, and British Citizenship was made attainable by simply obtaining a second British passport with the citizenship recorded as British Citizen (requiring a change to passport legislation as prior to 2002, it had been illegal to possess two British Passports). In March 2021, the government implemented a new visa policy towards foreigners, through which residency can be obtained by way of investing at least $2.5 million in "real estate, Bermuda government bonds, a contribution to the island's debt relief fund or the Bermuda Trust Fund, and charity", among other options. According to the Labour Minister, Jason Hayward, this step had to be taken to relieve some of the country's debt resulting from the Covid pandemic. Administrative divisions Bermuda is divided into nine parishes and two incorporated municipalities. Bermuda's nine parishes are: Devonshire Hamilton Paget Pembroke Sandys Smith's Southampton St George's Warwick Bermuda's two incorporated municipalities are: Hamilton (city) St George's (town) Bermuda's two informal villages are: Flatts Village Somerset Village Jones Village in Warwick, Cashew City (St. George's), Claytown (Hamilton), Middle Town (Pembroke), and Tucker's Town (St. George's) are neighbourhoods (the original settlement at Tucker's Town was replaced with a golf course in the 1920s and the few houses in the area today are mostly on the water's edge of Castle Harbour or the adjacent peninsula); Dandy Town and North Village are sports clubs, and Harbour View Village is a small public housing development. International relations As a British Overseas Territory, Bermuda does not have a seat in the United Nations; it is represented by Britain in matters of foreign affairs. To promote its economic interests abroad, Bermuda maintains representative offices in London and Washington, D.C. Only the United States and Portugal have full-time diplomatic representation in Bermuda (the U.S. maintains a Consulate-General, and Portugal maintains a Consulate), while 17 countries maintain honorary consuls in Bermuda. Bermuda's proximity to the US had made it attractive as the site for summit conferences between British prime ministers and US presidents. The first summit was held in December 1953, at the insistence of Prime Minister Winston Churchill, to discuss relations with the Soviet Union during the Cold War. Participants included Churchill, US president Dwight D. Eisenhower and French premier Joseph Laniel. In 1957 a second summit conference was held. The British prime minister, Harold Macmillan, arrived earlier than President Eisenhower, to demonstrate they were meeting on British territory, as tensions were still high regarding the previous year's conflict over the Suez Canal. Macmillan returned in 1961 for the third summit with President John F. Kennedy. The meeting was called to discuss Cold War tensions arising from construction of the Berlin Wall. The most recent summit conference in Bermuda between the two powers occurred in 1990, when British prime minister Margaret Thatcher met US president George H. W. Bush. Direct meetings between the president of the United States and the premier of Bermuda have been rare. The most recent meeting was on 23 June 2008, between Premier Ewart Brown and President George W. Bush. Prior to this, the leaders of Bermuda and the United States had not met at the White House since a 1996 meeting between Premier David Saul and President Bill Clinton. Bermuda has also joined several other jurisdictions in efforts to protect the Sargasso Sea. In 2013 and 2017 Bermuda chaired the United Kingdom Overseas Territories Association. Asylum offer to four former Guantánamo detainees On 11 June 2009, four Uyghurs who had been held in the United States Guantánamo Bay detention camp, in Cuba, were transferred to Bermuda. The four men were among 22 Uyghurs who claimed to be refugees who were captured in 2001 in Pakistan after fleeing the American aerial bombardment of Afghanistan. They were accused of training to assist the Taliban's military. They were cleared as safe for release from Guantánamo in 2005 or 2006, but US domestic law prohibited deporting them back to China, their country of citizenship, because the US government determined that China was likely to violate their human rights. In September 2008, the men were cleared of all suspicion and Judge Ricardo Urbina in Washington ordered their release. Congressional opposition to their admittance to the United States was very strong and the US failed to find a home for them until Bermuda and Palau agreed to accept the 22 men in June 2009. The secret bilateral discussions that led to prisoner transfers between the US and the devolved Bermuda government sparked diplomatic ire from the United Kingdom, which was not consulted on the move despite Bermuda being a British territory. The British Foreign Office issued the following statement: In August 2018, the four Uyghurs were granted limited citizenship in Bermuda. The men now have the same rights as Bermudians except the right to vote. British North America, British West Indies and the Caribbean Community The British Government originally grouped Bermuda with North America (given its proximity, and Bermuda having been established as an extension of the Colony of Virginia, and with Carolina Colony, the nearest landfall, having been settled from Bermuda). After the acknowledgement by the British Government of the independence of thirteen continental colonies (including Virginia and the Carolinas) in 1783, Bermuda was generally grouped regionally by the British Government with The Maritimes and Newfoundland and Labrador (and more widely, as part of British North America), substantially nearer to Bermuda than is the Caribbean. From 1783 through 1801, the British Empire, including British North America, was administered by the Home Office and by the Home Secretary, then from 1801 to 1854 by the War Office (which became the War and Colonial Office) and Secretary of State for War and Colonies (as the Secretary of State for War was renamed). From 1824, the British Empire was divided by the War and Colonial Office into four administrative departments, including North America, the West Indies, Mediterranean and Africa, and Eastern Colonies, of which North America included: North America Upper Canada, Lower Canada New Brunswick, Nova Scotia, Prince Edward Island Bermuda, Newfoundland The Colonial Office and War Office, and the Secretary of State for the Colonies and the Secretary of State for War, were separated in 1854. The War Office, from then until the 1867 confederation of the Dominion of Canada, split the military administration of the British colonial and foreign stations into nine districts: North America and North Atlantic; West Indies; Mediterranean; West Coast of Africa and South Atlantic; South Africa; Egypt and the Sudan; Indian Ocean; Australasia; China. North America and North Atlantic included the following 'stations' (or garrisons): North America and North Atlantic New Westminster (British Columbia) Newfoundland Quebec Halifax Kingston, Canada West Bermuda However, with the confederation of the Canadas and the Maritimes and their attainment of Dominion status in the 1860s, the British political, naval and military hierarchy in Bermuda became increasingly separated from that of the Canadian Government (the Royal Navy headquarters for the North America and West Indies Station had spent summers at Halifax, Nova Scotia, and winters at Bermuda, but settled at Bermuda year round with the Royal Naval Dockyard, Halifax finally being transferred to the Royal Canadian Navy in 1907, and the Bermuda Garrison had been placed under the military Commander-in-Chief America in New York during the American War of Independence, and had been part of the Nova Scotia Command thereafter, but became the separate Bermuda Command from the 1860s with the Major-General or Lieutenant-General appointed as Commander-in-Chief of Bermuda also filling the civil role of Governor of Bermuda), and Bermuda was increasingly perceived by the British Government as in, or at least grouped for convenience with, the British West Indies (although the established Church of England in Bermuda, which from 1825 to 1839 had been attached to the See of Nova Scotia) remained part of the Diocese of Newfoundland and Bermuda until 1879, when the Synod of the Church of England in Bermuda was formed and a Diocese of Bermuda became separate from the Diocese of Newfoundland, but continued to be grouped under the Bishop of Newfoundland and Bermuda until 1919, when Newfoundland and Bermuda each received its own bishop. Newfoundland attained Dominion status in 1907, leaving the nearest other territories to Bermuda that were still within the British Realm (a term which replaced Dominion in 1952 as the dominions and many colonies moved towards full political independence) as the British colonies in the British West Indies. Other denominations also at one time included Bermuda with Nova Scotia or Canada. Following the separation of the Church of England from the Roman Catholic Church, Roman Catholic worship was outlawed in England (subsequently Britain) and its colonies, including Bermuda, until the Roman Catholic Relief Act 1791, and operated thereafter under restrictions until the Twentieth Century. Once Roman Catholic worship was established, Bermuda formed part of the Archdiocese of Halifax, Nova Scotia until 1953, when it was separated to become the Apostolic Prefecture of Bermuda Islands. The congregation of the first African Methodist Episcopal Church in Bermuda (St. John African Methodist Episcopal Church, erected in 1885 in Hamilton Parish) had previously been part of the British Methodist Episcopal Church of Canada. Bermuda became an associate member of the Caribbean Community (CARICOM) in July 2003, despite not being in the Caribbean region. CARICOM is a socio-economic bloc of nations in or near the Caribbean Sea established in 1973. Other outlying member states include the Co-operative Republic of Guyana and the Republic of Suriname in South America, and Belize in Central America. The Turks and Caicos Islands, an associate member of CARICOM, and the Commonwealth of The Bahamas, a full member of CARICOM, are in the Atlantic, but close to the Caribbean. Other nearby nations or territories, such as the United States, are not members (although the US Commonwealth of Puerto Rico has observer status, and the United States Virgin Islands announced in 2007 that they would seek ties with CARICOM). Bermuda has minimal trade with the Caribbean region, and little in common with it economically, being roughly from the Caribbean Sea; it joined CARICOM primarily to strengthen cultural links with the region. Among some scholars, "the Caribbean" can be a socio-historical category, commonly referring to a cultural zone characterised by the legacy of slavery (a characteristic Bermuda shared with the Caribbean and the US) and the plantation system (which did not exist in Bermuda). It embraces the islands and parts of the neighbouring continent, and may be extended to include the Caribbean Diaspora overseas. The PLP, which was the party in government when the decision was made to join CARICOM, has been dominated for decades by West Indians and their descendants. The prominent roles of West Indians among Bermuda's black politicians and labour activists predated party politics in Bermuda, as exemplified by E. F. Gordon. The late PLP leader, Dame Lois Browne-Evans, and her Trinidadian-born husband, John Evans (who co-founded the West Indian Association of Bermuda in 1976), were prominent members of this group. A generation later, PLP politicians included Senator Rolfe Commissiong (son of Trinidadian musician Rudolph Patrick Commissiong). They have emphasised Bermuda's cultural connections with the West Indies. Many Bermudians, both black and white, who lack family connections to the West Indies have objected to this emphasis. The decision to join CARICOM stirred up a huge amount of debate and speculation among the Bermudian community and politicians. Opinion polls conducted by two Bermudian newspapers, The Royal Gazette and The Bermuda Sun, showed that clear majorities of Bermudians were opposed to joining CARICOM. The UBP, which had been in government from 1968 to 1998, argued that joining CARICOM was detrimental to Bermuda's interests, in that: Bermuda's trade with the West Indies is negligible, its primary economic partners being the US, Canada, and UK (it has no direct air or shipping links to Caribbean islands); CARICOM is moving towards a single economy; the Caribbean islands are generally competitors to Bermuda's already ailing tourism industry; and participation in CARICOM would involve considerable investment of money and the time of government officials that could more profitably be spent elsewhere. Police Law enforcement in Bermuda is provided chiefly by the Bermuda Police Service and is also supported with the Customs Department and Immigration Department. During certain times the Royal Bermuda Regiment can be called in to assist law enforcement personnel. Military and defence A former Imperial fortress colony once known as "the Gibraltar of the West" and "Fortress Bermuda", defence of Bermuda, as part of the British nation-state, is the responsibility of the British Government. For the first two centuries of settlement, the most potent armed force operating from Bermuda was its merchant shipping fleet, which turned to privateering at every opportunity. The Bermuda government maintained a local (infantry) militia and fortified coastal artillery batteries manned by volunteer artillerymen. Bermuda tended toward the Royalist side during the English Civil War, being the first of six colonies to recognise Charles II as King on the execution of his father, Charles I, in 1649, and was one of those targeted by the Rump Parliament in An Act for prohibiting Trade with the Barbadoes, Virginia, Bermuda and Antego, which was passed on 30 October 1650. With control of the "army" (the militia and coastal artillery), the colony's Royalists deposed the Governor, Captain Thomas Turner, elected John Trimingham to replace him, and exiled many of its Parliamentary leaning Independents to settle the Bahamas under William Sayle as the Eleutheran Adventurers. Bermuda's barrier reef, coastal artillery batteries and militia provided a defence too powerful for the fleet sent in 1651 by Parliament under the command of Admiral Sir George Ayscue to capture the Royalist colonies. The Parliamentary Navy was consequently forced to blockade Bermuda for several months 'til the Bermudians negotiated a peace. After the American Revolutionary War, Bermuda was established as the Western Atlantic headquarters of the North America Station (later called the North America and West Indies Station, and later still the America and West Indies Station as it absorbed other stations) of the Royal Navy. Once the Royal Navy established a base and dockyard defended by regular soldiers, however, the militias were disbanded following the War of 1812. At the end of the 19th century, the colony raised volunteer units to form a reserve for the military garrison. Due to its isolated location in the North Atlantic Ocean, Bermuda was vital to the Allies' war effort during both world wars of the 20th century, serving as a marshalling point for trans-Atlantic convoys, as well as a naval air base. By the Second World War, both the Royal Navy's Fleet Air Arm and the Royal Air Force were operating Seaplane bases on Bermuda. In May 1940, the US requested base rights in Bermuda from the United Kingdom, but British Prime Minister Winston Churchill was initially unwilling to accede to the American request without getting something in return. In September 1940, as part of the Destroyers for Bases Agreement, the UK granted the US base rights in Bermuda. Bermuda and Newfoundland were not originally included in the agreement, but both were added to it, with no war material received by the UK in exchange. One of the terms of the agreement was that the airfield the US Army built would be used jointly by the US and the UK (which it was for the duration of the war, with RAF Transport Command relocating there from Darrell's Island in 1943). The US Army established the Bermuda Base Command in 1941 to co-ordinate its air, anti-aircraft, and coast artillery assets during the war. The US Navy operated a submarine base on Ordnance Island from 1942 through 1945. Construction began in 1941 of two airbases consisting of of land, largely reclaimed from the sea. For many years, Bermuda's bases were used by US Air Force transport and refuelling aircraft and by US Navy aircraft patrolling the Atlantic for enemy submarines, first German and, later, Soviet. The principal installation, Kindley Air Force Base on the eastern coast, was transferred to the US Navy in 1970 and redesignated Naval Air Station Bermuda. As a naval air station, the base continued to host both transient and deployed USN and USAF aircraft, as well as transitioning or deployed Royal Air Force and Canadian Forces aircraft. The original NAS Bermuda on the west side of the island, a seaplane base until the mid-1960s, was designated as the Naval Air Station Bermuda Annex. It provided optional anchorage and/or dockage facilities for transiting US Navy, US Coast Guard and NATO vessels, depending on size. An additional US Navy compound known as Naval Facility Bermuda (NAVFAC Bermuda), a submarine-detecting SOSUS station, was located to the west of the Annex near a Canadian Forces communications facility in the Tudor Hill area; it was converted from a US Army coast artillery bunker in 1954 and operated until 1995. Although leased for 99 years, US forces withdrew in 1995, as part of the wave of base closures following the end of the Cold War. Canada, which had operated a war-time naval base, HMCS Somers Isles, on the old Royal Navy base at Convict Bay, St George's, also established a radio-listening post at Daniel's Head in the West End of the islands during this time. In the 1950s, after the end of World War II, the Royal Naval dockyard and the military garrison were closed. A small Royal Navy supply base, HMS Malabar, continued to operate within the dockyard area, supporting transiting Royal Navy ships and submarines until it, too, was closed in 1995, along with the American and Canadian bases. Bermudians served in the British armed forces during both World War I and World War II. After the latter, Major-General Glyn Charles Anglim Gilbert, Bermuda's highest-ranking soldier, was instrumental in developing the Bermuda Regiment. A number of other Bermudians and their descendants had preceded him into senior ranks, including Bahamian-born Admiral Lord Gambier, and Bermudian-born Royal Marines Brigadier Harvey. When promoted to brigadier at age 39, following his wounding at the Anzio landings, Harvey became the youngest-ever Royal Marine Brigadier. The Cenotaph in front of the Cabinet Building (in Hamilton) was erected in tribute to Bermuda's Great War dead (the tribute was later extended to Bermuda's Second World War dead) and is the site of the annual Remembrance Day commemoration. Today, the only military unit remaining in Bermuda, other than naval and army cadet corps, is the Royal Bermuda Regiment, an amalgam of the voluntary units originally formed toward the end of the 19th century. Although the Regiment's predecessors were voluntary units, until 2018 the modern body was formed primarily by conscription: balloted males were required to serve for three years, two months part-time, once they turn 18. Conscription was abolished 1 July 2018. In early 2020 Bermuda formed the Bermuda Coast Guard. Its 24-hour on-duty service includes search and rescue, counter-narcotics operations, border control, and protection of Bermuda's maritime interests. The Bermuda Coast Guard will interact with the Bermuda Regiment, Bermuda Police Service. Economy Banking and other financial services now form the largest sector of the economy at about 85% of GDP, with tourism being the second largest industry at 5%. Industrial and agriculture activities occur; however, these are on a very limited scale and Bermuda is heavily reliant on imports. Living standards are high and as of 2019 Bermuda has the 6th-highest GDP per capita in the world. 1890s to 1920s: economy severely affected by lily virus Early Easter Lily bulb exports to New York—then vital financially for Bermuda—became badly diseased from the late 19th century to the mid-1920s. Lawrence Ogilvie, the Department of Agriculture plant pathologist saved the industry by identifying the problem as a virus (not aphid damage as previously thought) and instituting controls in the fields and packing houses. Exports showed a marked improvement: from 23 cases of lily bulbs in 1918, to 6,043 cases in 1927 from the 204 lily fields then in existence. Still in his 20s at the time, Ogilvie was professionally honoured by an article in Nature magazine. The lily export trade continued to flourish until the 1940s when the Japanese captured much of the market. Currency In 1970, the country switched its currency from the Bermudian pound to the Bermudian dollar, which is pegged at par with the US dollar. US notes and coins are used interchangeably with Bermudian notes and coins within the islands for most practical purposes; however, banks levy an exchange rate fee for the purchase of US dollars with Bermudian dollars. The Bermuda Monetary Authority is the issuing authority for all banknotes and coins and regulates financial institutions. Finance Bermuda is an offshore financial centre, which results from its minimal standards of business regulation/laws and direct taxation on personal or corporate income. It has one of the highest consumption taxes in the world and taxes all imports in lieu of an income tax system. Bermuda's consumption tax is equivalent to local income tax to local residents and funds government and infrastructure expenditures. The local tax system depends upon import duties, payroll taxes and consumption taxes. Foreign private individuals cannot easily open bank accounts or subscribe to mobile phone or internet services. Having no corporate income tax, Bermuda is a popular tax avoidance location. Google, for example, is known to have shifted over $10 billion in revenue to its Bermuda subsidiary utilising the Double Irish and Dutch Sandwich tax avoidance strategies, reducing its 2011 tax liability by $2 billion. The Bermuda Black Hole is another tax avoidance method in which untaxed profits end up in Bermuda. Large numbers of leading international insurance companies operate in Bermuda. Those internationally owned and operated businesses that are physically based in Bermuda (around four hundred) are represented by the Association of Bermuda International Companies (ABIC). In total, over 15,000 exempted or international companies are currently registered with the Registrar of Companies in Bermuda, most of which hold no office space or employees. The Bermuda Stock Exchange (BSX) specialises in listing and trading of capital market instruments such as equities, debt issues, funds (including hedge fund structures) and depository receipt programmes. The BSX is a full member of the World Federation of Exchanges and is located in an OECD member nation. It also has Approved Stock Exchange status under Australia's Foreign Investment Fund (FIF) taxation rules and Designated Investment Exchange status by the UK's Financial Services Authority. Four banks operate in Bermuda, having consolidated total assets of $24.3 billion (March 2014). Tourism Tourism is Bermuda's second-largest industry, with the island attracting over half a million visitors annually, of whom more than 80% are from the United States. Other significant sources of visitors are from Canada and the United Kingdom. However, the sector is vulnerable to external shocks, such as the 2008 recession. Housing The affordability of housing became a prominent issue during Bermuda's business peak in 2005 but has softened with the decline of Bermuda's real estate prices. The World Factbook lists the average cost of a house in June 2003 as $976,000, while real estate agencies have claimed that this figure had risen to between $1.6 million and $1.845 million by 2007, though such high figures have been disputed. Education The Bermuda Education Act 1996 requires that only three categories of schools can operate in the Bermuda Education system: An aided school has all or a part of its property vested in a body of trustees or board of governors and is partially maintained by public funding or, since 1965 and the desegregation of schools, has received a grant-in-aid out of public funds. A maintained school has the whole of its property belonging to the Government and is fully maintained by public funds. A private school, not maintained by public funds and which has not, since 1965 and the desegregation of schools, received any capital grant-in-aid out of public funds. The private school sector consists of six traditional private schools, two of which are religious schools, and the remaining four are secular with one of these being a single-gender school and another a Montessori school. Also, within the private sector there are a number of home schools, which must be registered with the government and receive minimal government regulation. The only boys' school opened its doors to girls in the 1990s, and in 1996, one of the aided schools became a private school. Prior to 1950, the Bermuda school system was racially segregated. When the desegregation of schools was enacted in 1965, two of the formerly maintained "white" schools and both single-sex schools opted to become private schools. The rest became part of the public school system and were either aided or maintained. There are 38 schools in the Bermuda Public School System, including 10 preschools, 18 primary schools, 5 middle schools, 2 senior schools (The Berkeley Institute and Cedarbridge Academy), 1 school for students with physical and cognitive challenges, and 1 for students with behavioural problems. There is one aided primary school, two aided middle schools, and one aided senior school. Since 2010, Portuguese has been taught as an optional foreign language in the Bermudian school system. For higher education, the Bermuda College offers various associate degrees and other certificate programmes. Bermuda does not have any Bachelor-level colleges or universities. Bermuda's graduates usually attend Bachelor-level universities in the United States, Canada and the United Kingdom. In May 2009, the Bermudian Government's application was approved to become a contributory member of the University of the West Indies (UWI). Bermuda's membership enabled Bermudian students to enter the university at an agreed-upon subsidised rate by 2010. UWI also agreed that its Open Campus (online degree courses) would become open to Bermudian students in the future, with Bermuda becoming the 13th country to have access to the Open Campus. In 2010, it was announced that Bermuda would be an "associate contributing country" due to local Bermudian laws. Culture Bermuda's culture is a mixture of the various sources of its population: Native American, Spanish-Caribbean, English, Irish, and Scots cultures were evident in the 17th century, and became part of the dominant British culture. English is the primary and official language. Due to 160 years of immigration from Portuguese Atlantic islands (primarily the Azores, though also from Madeira and the Cape Verde Islands), a portion of the population also speaks Portuguese. There are strong British influences, together with Afro-Caribbean ones. The first notable, and historically important, book credited to a Bermudian was The History of Mary Prince, a slave narrative by Mary Prince. The book was published in 1831 at the height of Great Britain's abolitionist movement. Ernest Graham Ingham, an expatriate author, published his books at the turn of the 19th and 20th centuries. The novelist Brian Burland (1931– 2010) achieved a degree of success and acclaim internationally. More recently, Angela Barry has won critical recognition for her published fiction. Arts West Indian musicians introduced calypso music when Bermuda's tourist industry was expanded with the increase of visitors brought by post-Second World War aviation. Local icons the Talbot Brothers performed calypso music for many decades both in Bermuda and the United States, and appeared on the Ed Sullivan Show. While calypso appealed more to tourists than to the local residents, reggae has been embraced by many Bermudians since the 1970s with the influx of Jamaican immigrants. Noted Bermudian musicians include operatic tenor Gary Burgess; jazz pianist Lance Hayward; singer-songwriter and poet, Heather Nova, and her brother Mishka, reggae musician; classical musician and conductor Kenneth Amis; and more recently, dancehall artist Collie Buddz. The dances of the Gombey dancers, seen at many events, are strongly influenced by African, Caribbean and British cultural traditions. Alfred Birdsey was one of the more famous and talented watercolourists, known for his impressionistic landscapes of Hamilton, St George's, and the surrounding sailboats, homes, and bays of Bermuda. Hand-carved cedar sculptures are another speciality. In 2010, his sculpture We Arrive was unveiled in Barr's Bay Park, overlooking Hamilton Harbour, to commemorate the freeing of slaves in 1835 from the American brig Enterprise. Local resident Tom Butterfield founded the Masterworks Museum of Bermuda Art in 1986, initially featuring works about Bermuda by artists from other countries. He began with pieces by American artists, such as Winslow Homer, Charles Demuth, and Georgia O'Keeffe, who had lived and worked on Bermuda. In 2008, the museum opened its new building, constructed within the Botanical Gardens. Bermuda hosts an annual international film festival, which shows many independent films. One of the founders is film producer and director Arthur Rankin Jr., co-founder of the Rankin/Bass production company. Sport Many sports popular today were formalised by British public schools and universities in the 19th century. These schools produced the civil servants and military and naval officers required to build and maintain the British Empire, and team sports were considered a vital tool for training their students to think and act as part of a team. Former public schoolboys continued to pursue these activities, and founded organisations such as the Football Association (FA). Bermuda's role as the primary Royal Navy base in the Western Hemisphere ensured that the naval and military officers quickly introduced the newly formalised sports to Bermuda, including cricket, football, rugby football, and even tennis and rowing. Bermuda's national cricket team participated in the Cricket World Cup 2007 in the West Indies but were knocked out of the World Cup. The Bermuda national football team managed to qualify to the 2019 CONCACAF Gold Cup, the country's first ever major football competition. In 2007, Bermuda hosted the 25th PGA Grand Slam of Golf. This 36-hole event was held on 16–17 October 2007, at the Mid Ocean Club in Tucker's Town. This season-ending tournament is limited to four golfers: the winners of the Masters, U.S. Open, The Open Championship and PGA Championship. The event returned to Bermuda in 2008 and 2009. One-armed Bermudian golfer Quinn Talbot was both the United States National Amputee Golf Champion for five successive years and the British World One-Arm Golf Champion. The Government announced in 2006 that it would provide substantial financial support to Bermuda's cricket and football teams. Football did not become popular with Bermudians until after the Second World War. Bermuda's most prominent footballers are Clyde Best, Shaun Goater, Kyle Lightbourne, Reggie Lambe, Sam Nusum and Nahki Wells. In 2006, the Bermuda Hogges were formed as the nation's first professional football team to raise the standard of play for the Bermuda national football team. The team played in the United Soccer Leagues Second Division but folded in 2013. Sailing, fishing and equestrian sports are popular with both residents and visitors alike. The prestigious Newport–Bermuda Yacht Race is a more than 100-year-old tradition, with boats racing between Newport, Rhode Island, and Bermuda. In 2007, the 16th biennial Marion-Bermuda yacht race occurred. A sport unique to Bermuda is racing the Bermuda Fitted Dinghy. International One Design racing also originated in Bermuda. At the 2004 Summer Olympics, Bermuda competed in sailing, athletics, swimming, diving, triathlon and equestrian events. In those Olympics, Bermuda's Katura Horton-Perinchief made history by becoming the first black female diver to compete in the Olympic Games. Bermuda has had two Olympic medallists, Clarence Hill - who won a bronze medal in boxing - and Flora Duffy, who won a gold medal in triathlon. It is tradition for Bermuda to march in the Opening Ceremony in Bermuda shorts, regardless of the summer or winter Olympic celebration. Bermuda also competes in the biennial Island Games, which it hosted in 2013. In 1998, Bermuda established its own Basketball Association. Healthcare The Bermuda Hospitals Board operates the King Edward VII Memorial Hospital, located in Paget Parish, and the Mid-Atlantic Wellness Institute, located in Devonshire Parish. Boston's Lahey Medical Center has an established visiting specialists program on the island which provides Bermudians and expats with access to specialists regularly on the island. There were about 6,000 hospital admissions, 30,000 emergency department attendances and 6,300 outpatient procedures in 2017. Unlike the other territories that still remain under British rule, Bermuda does not have national healthcare. Employers must provide a healthcare plan and pay for up to 50% of the cost for each employee. Healthcare is a mandatory requirement and is expensive, even with the help provided by employers. There are only a few approved healthcare providers that offer insurance to Bermudians. , these were the Bermudian government's Health Insurance Department, three other approved licensed health insurance companies, and three approved health insurance schemes (provided by the Bermudian government for its employees and by two banks). There are no paramedics on the island. The Bermuda Hospitals Board said in 2018 that they were not vital in Bermuda because of its small size. Nurse practitioners on the island, of which there are not many, can be granted authority to write prescriptions "under the authority of a medical practitioner". COVID-19 pandemic The Minister for Health during the COVID-19 pandemic was Kim Wilson, who led the territory's approach with "an abundance of caution."

Bolivia

Bolivia, officially the Plurinational State of Bolivia, is a landlocked country located in western-central South America. It is bordered by Brazil to the north and east, Paraguay to the southeast, Argentina to the south, Chile to the southwest, and Peru to the west. The seat of government and administrative capital is La Paz, which contains the executive, legislative, and electoral branches of government, while the constitutional capital is Sucre, the seat of the judiciary. The largest city and principal industrial center is Santa Cruz de la Sierra, located on the Llanos Orientales (tropical lowlands), a mostly flat region in the east of the country. The sovereign state of Bolivia is a constitutionally unitary state, divided into nine departments. Its geography varies from the peaks of the Andes in the West, to the Eastern Lowlands, situated within the Amazon basin. One-third of the country is within the Andean mountain range. With of area, Bolivia is the fifth largest country in South America, after Brazil, Argentina, Peru, and Colombia (and alongside Paraguay, one of the only two landlocked countries in the Americas), the 27th largest in the world, the largest landlocked country in the Southern Hemisphere, and the world's seventh largest landlocked country, after Kazakhstan, Mongolia, Chad, Niger, Mali, and Ethiopia. The country's population, estimated at 12 million, is multiethnic, including Amerindians, Mestizos, Europeans, Asians, and Africans. Spanish is the official and predominant language, although 36 indigenous languages also have official status, of which the most commonly spoken are Guarani, Aymara, and Quechua languages. Before Spanish colonization, the Andean region of Bolivia was part of the Inca Empire, while the northern and eastern lowlands were inhabited by independent tribes. Spanish conquistadors arriving from Cusco and Asunción took control of the region in the 16th century. During the Spanish colonial period Bolivia was administered by the Real Audiencia of Charcas. Spain built its empire in large part upon the silver that was extracted from Bolivia's mines. After the first call for independence in 1809, 16 years of war followed before the establishment of the Republic, named for Simón Bolívar. Over the course of the 19th and early 20th century Bolivia lost control of several peripheral territories to neighboring countries including the seizure of its coastline by Chile in 1879 and Acre territory to Brazil. Bolivia experienced a succession of military and civilian governments until 1971, when Hugo Banzer led a CIA-supported coup d'état that replaced the socialist government of Juan José Torres with a military dictatorship. Banzer's regime cracked down on left-wing and socialist opposition and other forms of dissent, resulting in the torture and deaths of a number of Bolivian citizens. Banzer was ousted in 1978 and later returned as the democratically elected president of Bolivia from 1997 to 2001. Under the 2006–2019 presidency of Evo Morales the country saw significant economic growth and political stability. Modern Bolivia is a charter member of the UN, IMF, NAM, OAS, ACTO, Bank of the South, ALBA, and USAN. Bolivia remains the second poorest country in South America, though it has slashed poverty rates and has the fastest growing economy in South America (in terms of GDP). It is a developing country. Its main economic activities include agriculture, forestry, fishing, mining, and manufacturing goods such as textiles, clothing, refined metals, and refined petroleum. Bolivia is very rich in minerals, including tin, silver, lithium, and copper. Bolivia is also known for its production of coca leaves and refined cocaine. In 2021, estimated coca cultivation and cocaine production was 39,700 hectares and 317 metric tons, respectively. Etymology Bolivia is named after Simón Bolívar, a Venezuelan leader in the Spanish American wars of independence. The leader of Venezuela, Antonio José de Sucre, had been given the option by Bolívar to either unite Charcas (present-day Bolivia) with the newly formed Republic of Peru, to unite with the United Provinces of the Río de la Plata, or to formally declare its independence from Spain as a wholly independent state. Sucre opted to create a brand new state and on 6 August 1825, with local support, named it in honor of Simón Bolívar. The original name was Republic of Bolívar. Some days later, congressman Manuel Martín Cruz proposed: "If from Romulus, Rome, then from Bolívar, Bolivia" (). The name was approved by the Republic on 3 October 1825. In 2009, a new constitution changed the country's official name to "Plurinational State of Bolivia" to reflect the multi-ethnic nature of the country and the strengthened rights of Bolivia's indigenous peoples under the new constitution. History Pre-colonial The region now known as Bolivia had been occupied for over 2,500 years when the Aymara arrived. However, present-day Aymara associate themselves with the ancient civilization of the Tiwanaku Empire which had its capital at Tiwanaku, in Western Bolivia. The capital city of Tiwanaku dates from as early as 1500 BC when it was a small, agriculturally-based village. The Aymara community grew to urban proportions between AD 600 and AD 800, becoming an important regional power in the southern Andes. According to early estimates, the city covered approximately at its maximum extent and had between 15,000 and 30,000 inhabitants. In 1996 satellite imaging was used to map the extent of fossilized suka kollus (flooded raised fields) across the three primary valleys of Tiwanaku, arriving at population-carrying capacity estimates of anywhere between 285,000 and 1,482,000 people. Around AD 400, Tiwanaku went from being a locally dominant force to a predatory state. Tiwanaku expanded its reaches into the Yungas and brought its culture and way of life to many other cultures in Peru, Bolivia, and Chile. Tiwanaku was not a violent culture in many respects. To expand its reach, Tiwanaku exercised great political astuteness, creating colonies, fostering trade agreements (which made the other cultures rather dependent), and instituting state cults. As the rainfall decreased, the surplus of food decreased, and thus the amount available to underpin the power of the elites. Tiwanaku disappeared around AD 1000. The area remained uninhabited for centuries thereafter. Between 1438 and 1527, the Inca empire expanded from its capital at Cusco, Peru. It gained control over much of what is now Andean Bolivia and extended its control into the fringes of the Amazon basin. Colonial period The Spanish conquest of the Inca empire began in 1524 and was mostly completed by 1533. The territory now called Bolivia was known as Charcas, and was under the authority of the Viceroy of Peru in Lima. Local government came from the Audiencia de Charcas located in Chuquisaca (La Plata—modern Sucre). Founded in 1545 as a mining town, Potosí soon produced fabulous wealth, becoming the largest city in the New World with a population exceeding 150,000 people. By the late 16th century, Bolivian silver was an important source of revenue for the Spanish Empire. A steady stream of natives served as labor force under the brutal, slave conditions of the Spanish version of the pre-Columbian draft system called the mita. Charcas was transferred to the Viceroyalty of the Río de la Plata in 1776 and the people from Buenos Aires, the capital of the Viceroyalty, coined the term "Upper Peru" () as a popular reference to the Royal Audiencia of Charcas. Túpac Katari led the indigenous rebellion that laid siege to La Paz in March 1781, during which 20,000 people died. As Spanish royal authority weakened during the Napoleonic Wars, sentiment against colonial rule grew. Independence and subsequent wars The struggle for independence started in the city of Sucre on 25 May 1809 and the Chuquisaca Revolution (Chuquisaca was then the name of the city) is known as the first cry of Freedom in Latin America. That revolution was followed by the La Paz revolution on 16 July 1809. The La Paz revolution marked a complete split with the Spanish government, while the Chuquisaca Revolution established a local independent junta in the name of the Spanish King deposed by Napoleon Bonaparte. Both revolutions were short-lived and defeated by the Spanish authorities in the Viceroyalty of the Rio de La Plata, but the following year the Spanish American wars of independence raged across the continent. Bolivia was captured and recaptured many times during the war by the royalists and patriots. Buenos Aires sent three military campaigns, all of which were defeated, and eventually limited itself to protecting the national borders at Salta. Bolivia was finally freed of Royalist dominion by Marshal Antonio José de Sucre, with a military campaign coming from the North in support of the campaign of Simón Bolívar. After 16 years of war the Republic was proclaimed on 6 August 1825. In 1836, Bolivia, under the rule of Marshal Andrés de Santa Cruz, invaded Peru to reinstall the deposed president, General Luis José de Orbegoso. Peru and Bolivia formed the Peru-Bolivian Confederation, with de Santa Cruz as the Supreme Protector. Following tension between the Confederation and Chile, Chile declared war on 28 December 1836. Argentina separately declared war on the Confederation on 9 May 1837. The Peruvian-Bolivian forces achieved several major victories during the War of the Confederation: the defeat of the Argentine expedition and the defeat of the first Chilean expedition on the fields of Paucarpata near the city of Arequipa. The Chilean army and its Peruvian rebel allies surrendered unconditionally and signed the Paucarpata Treaty. The treaty stipulated that Chile would withdraw from Peru-Bolivia, Chile would return captured Confederate ships, economic relations would be normalized, and the Confederation would pay Peruvian debt to Chile. However, the Chilean government and public rejected the peace treaty. Chile organized a second attack on the Confederation and defeated it in the Battle of Yungay. After this defeat, Santa Cruz resigned and went to exile in Ecuador and then Paris, and the Peruvian-Bolivian Confederation was dissolved. Following the renewed independence of Peru, Peruvian president General Agustín Gamarra invaded Bolivia. On 18 November 1841, the battle de Ingavi took place, in which the Bolivian Army defeated the Peruvian troops of Gamarra (killed in the battle). After the victory, Bolivia invaded Perú on several fronts. The eviction of the Bolivian troops from the south of Peru would be achieved by the greater availability of material and human resources of Peru; the Bolivian Army did not have enough troops to maintain an occupation. In the district of Locumba – Tacna, a column of Peruvian soldiers and peasants defeated a Bolivian regiment in the so-called Battle of Los Altos de Chipe (Locumba). In the district of Sama and in Arica, the Peruvian colonel José María Lavayén organized a troop that managed to defeat the Bolivian forces of Colonel Rodríguez Magariños and threaten the port of Arica. In the battle of Tarapacá on 7 January 1842, Peruvian militias formed by the commander Juan Buendía defeated a detachment led by Bolivian colonel José María García, who died in the confrontation. Bolivian troops left Tacna, Arica and Tarapacá in February 1842, retreating towards Moquegua and Puno. The battles of Motoni and Orurillo forced the withdrawal of Bolivian forces occupying Peruvian territory and exposed Bolivia to the threat of counter-invasion. The Treaty of Puno was signed on 7 June 1842, ending the war. However, the climate of tension between Lima and La Paz would continue until 1847, when the signing of a Peace and Trade Treaty became effective. A period of political and economic instability in the early-to-mid-19th century weakened Bolivia. In addition, during the War of the Pacific (1879–83), Chile occupied vast territories rich in natural resources south west of Bolivia, including the Bolivian coast. Chile took control of today's Chuquicamata area, the adjoining rich salitre (saltpeter) fields, and the port of Antofagasta among other Bolivian territories. Since independence, Bolivia has lost over half of its territory to neighboring countries. Through diplomatic channels in 1909, it lost the basin of the Madre de Dios River and the territory of the Purus in the Amazon, yielding 250,000 km2 to Peru. It also lost the state of Acre, in the Acre War, important because this region was known for its production of rubber. Peasants and the Bolivian army fought briefly but after a few victories, and facing the prospect of a total war against Brazil, it was forced to sign the Treaty of Petrópolis in 1903, in which Bolivia lost this rich territory. Popular myth has it that Bolivian president Mariano Melgarejo (1864–71) traded the land for what he called "a magnificent white horse" and Acre was subsequently flooded by Brazilians, which ultimately led to confrontation and fear of war with Brazil. In the late 19th century, an increase in the world price of silver brought Bolivia relative prosperity and political stability. Early 20th century During the early 20th century, tin replaced silver as the country's most important source of wealth. A succession of governments controlled by the economic and social elite followed laissez-faire capitalist policies through the first 30 years of the 20th century. Living conditions of the native people, who constitute most of the population, remained deplorable. With work opportunities limited to primitive conditions in the mines and in large estates having nearly feudal status, they had no access to education, economic opportunity, and political participation. Bolivia's defeat by Paraguay in the Chaco War (1932–1935), where Bolivia lost a great part of the Gran Chaco region in dispute, marked a turning-point. On 7 April 1943, Bolivia entered World War II, joining part of the Allies, which caused president Enrique Peñaranda to declare war on the Axis powers of Germany, Italy and Japan. The Revolutionary Nationalist Movement (MNR), the most historic political party, emerged as a broad-based party. Denied its victory in the 1951 presidential elections, the MNR led a successful revolution in 1952. Under President Víctor Paz Estenssoro, the MNR, having strong popular pressure, introduced universal suffrage into his political platform and carried out a sweeping land-reform promoting rural education and nationalization of the country's largest tin mines. Late 20th century Twelve years of tumultuous rule left the MNR divided. In 1964, a military junta overthrew President Estenssoro at the outset of his third term. The 1969 death of President René Barrientos Ortuño, a former member of the junta who was elected president in 1966, led to a succession of weak governments. Alarmed by the rising Popular Assembly and the increase in the popularity of President Juan José Torres, the military, the MNR, and others installed Colonel (later General) Hugo Banzer Suárez as president in 1971. He returned to the presidency in 1997 through 2001. Juan José Torres, who had fled Bolivia, was kidnapped and assassinated in 1976 as part of Operation Condor, the U.S.-supported campaign of political repression by South American right-wing dictators. The United States' Central Intelligence Agency (CIA) financed and trained the Bolivian military dictatorship in the 1960s. The revolutionary leader Che Guevara was killed by a team of CIA officers and members of the Bolivian Army on 9 October 1967, in Bolivia. Félix Rodríguez was a CIA officer on the team with the Bolivian Army that captured and shot Guevara. Rodriguez said that after he received a Bolivian presidential execution order, he told "the soldier who pulled the trigger to aim carefully, to remain consistent with the Bolivian government's story that Che had been killed in action during a clash with the Bolivian army." Rodriguez said the US government had wanted Che in Panama, and "I could have tried to falsify the command to the troops, and got Che to Panama as the US government said they had wanted", but that he had chosen to "let history run its course" as desired by Bolivia. Elections in 1979 and 1981 were inconclusive and marked by fraud. There were coups d'état, counter-coups, and caretaker governments. In 1980, General Luis García Meza Tejada carried out a ruthless and violent coup d'état that did not have popular support. The Bolivian Workers' Center, which tried to resist the putsch, was violently repressed. More than a thousand people were killed in less than a year. Cousin of one of the most important narco-trafficker of the country, Luis García Meza Tejada favors the production of cocaine. He pacified the people by promising to remain in power only for one year. At the end of the year, he staged a televised rally to claim popular support and announced, "", or, "All right; I'll stay [in office]". After a military rebellion forced out Meza in 1981, three other military governments in 14 months struggled with Bolivia's growing problems. Unrest forced the military to convoke the Congress, elected in 1980, and allow it to choose a new chief executive. In October 1982, Hernán Siles Zuazo again became president, 22 years after the end of his first term of office (1956–1960). Democratic transition In 1993, Gonzalo Sánchez de Lozada was elected president in alliance with the Tupac Katari Revolutionary Liberation Movement, which inspired indigenous-sensitive and multicultural-aware policies. Sánchez de Lozada pursued an aggressive economic and social reform agenda. The most dramatic reform was privatization under the "capitalization" program, under which investors, typically foreign, acquired 50% ownership and management control of public enterprises in return for agreed upon capital investments. In 1993, Sanchez de Lozada introduced the Plan de Todos, which led to the decentralization of government, introduction of intercultural bilingual education, implementation of agrarian legislation, and privatization of state owned businesses. The plan explicitly stated that Bolivian citizens would own a minimum of 51% of enterprises; under the plan, most state-owned enterprises (SOEs), though not mines, were sold. This privatization of SOEs led to a neoliberal structuring. The reforms and economic restructuring were strongly opposed by certain segments of society, which instigated frequent and sometimes violent protests, particularly in La Paz and the Chapare coca-growing region, from 1994 through 1996. The indigenous population of the Andean region was not able to benefit from government reforms. During this time, the umbrella labor-organization of Bolivia, the Central Obrera Boliviana (COB), became increasingly unable to effectively challenge government policy. A teachers' strike in 1995 was defeated because the COB could not marshal the support of many of its members, including construction and factory workers. 1997–2002 General Banzer presidency In the 1997 elections, General Hugo Banzer, leader of the Nationalist Democratic Action party (ADN) and former dictator (1971–1978), won 22% of the vote, while the MNR candidate won 18%. At the outset of his government, President Banzer launched a policy of using special police-units to eradicate physically the illegal coca of the Chapare region. The MIR of Jaime Paz Zamora remained a coalition-partner throughout the Banzer government, supporting this policy (called the Dignity Plan). The Banzer government basically continued the free-market and privatization-policies of its predecessor. The relatively robust economic growth of the mid-1990s continued until about the third year of its term in office. After that, regional, global and domestic factors contributed to a decline in economic growth. Financial crises in Argentina and Brazil, lower world prices for export commodities, and reduced employment in the coca sector depressed the Bolivian economy. The public also perceived a significant amount of public sector corruption. These factors contributed to increasing social protests during the second half of Banzer's term. Between January 1999 and April 2000, large-scale protests erupted in Cochabamba, Bolivia's third largest city at the time, in response to the privatization of water resources by foreign companies and a subsequent doubling of water prices. On 6 August 2001, Banzer resigned from office after being diagnosed with cancer. He died less than a year later. Vice President Jorge Fernando Quiroga Ramírez completed the final year of his term. 2002–2005 Sánchez de Lozada / Mesa presidency In the June 2002 national elections, former President Gonzalo Sánchez de Lozada (MNR) placed first with 22.5% of the vote, followed by coca-advocate and native peasant-leader Evo Morales (Movement Toward Socialism, MAS) with 20.9%. A July agreement between the MNR and the fourth-place MIR, which had again been led in the election by former President Jaime Paz Zamora, virtually ensured the election of Sánchez de Lozada in the congressional run-off, and on 6 August he was sworn in for the second time. The MNR platform featured three overarching objectives: economic reactivation (and job creation), anti-corruption, and social inclusion. In 2003, the Bolivian gas conflict broke out. On 12 October 2003, the government imposed martial law in El Alto after 16 people were shot by the police and several dozen wounded in violent clashes. Faced with the option of resigning or more bloodshed, Sánchez de Lozada offered his resignation in a letter to an emergency session of Congress. After his resignation was accepted and his vice president, Carlos Mesa, invested, he left on a commercially scheduled flight for the United States. The country's internal situation became unfavorable for such political action on the international stage. After a resurgence of gas protests in 2005, Carlos Mesa attempted to resign in January 2005, but his offer was refused by Congress. On 22 March 2005, after weeks of new street protests from organizations accusing Mesa of bowing to U.S. corporate interests, Mesa again offered his resignation to Congress, which was accepted on 10 June. The chief justice of the Supreme Court, Eduardo Rodríguez, was sworn as interim president to succeed the outgoing Carlos Mesa. 2005–2019 Morales presidency Evo Morales won the 2005 presidential election with 53.7% of the votes in Bolivian elections. On 1 May 2006, Morales announced his intent to re-nationalize Bolivian hydrocarbon assets following protests which demanded this action. Fulfilling a campaign promise, on 6 August 2006, Morales opened the Bolivian Constituent Assembly to begin writing a new constitution aimed at giving more power to the indigenous majority. 2009 marked the creation of a new constitution and the renaming of the country to the Plurinational State of Bolivia. The previous constitution did not allow a consecutive reelection of a president, but the new constitution allowed for just one reelection, starting the dispute if Evo Morales was enabled to run for a second term arguing he was elected under the last constitution. This also triggered a new general election in which Evo Morales was re-elected with 61.36% of the vote. His party, Movement for Socialism, also won a two-thirds majority in both houses of the National Congress. By 2013, after being reelected under the new constitution, Evo Morales and his party attempted a third term as President of Bolivia. The opposition argued that a third term would be unconstitutional, but the Bolivian Constitutional Court ruled that Morales' first term under the previous constitution did not count towards his term limit. This allowed Evo Morales to run for a third term in 2014, and he was re-elected with 64.22% of the vote. During his third term, Evo Morales began to plan for a fourth, and the 2016 Bolivian constitutional referendum asked voters to override the constitution and allow Evo Morales to run for an additional term in office. Morales narrowly lost the referendum; however, in 2017 his party then petitioned the Bolivian Constitutional Court to override the constitution on the basis that the American Convention on Human Rights made term limits a human rights violation. The Inter-American Court of Human Rights determined that term limits are not a human rights violation in 2018; however, once again the Bolivian Constitutional Court ruled that Morales has permission to run for a fourth term in the 2019 elections, and this permission was not retracted. "[T]he country's highest court overruled the constitution, scrapping term limits altogether for every office. Morales can now run for a fourth term in 2019 – and for every election thereafter." The revenues generated by the partial nationalization of hydrocarbons made it possible to finance several social measures: the Renta Dignidad (or old age minimum) for people over 60 years old; the Juana Azurduy voucher (named after the revolutionary Juana Azurduy de Padilla, 1780–1862), which ensures the complete coverage of medical expenses for pregnant women and their children in order to fight infant mortality; the Juancito Pinto voucher (named after a child hero of the Pacific War, 1879–1884), an aid paid until the end of secondary school to parents whose children are in school in order to combat school dropout, and the Single Health System, which since 2018 has offered all Bolivians free medical care. The reforms adopted have made the Bolivian economic system the most successful and stable in the region. Between 2006 and 2019, GDP has grown from $9 billion to over $40 billion, real wages have increased, GDP per capita has tripled, foreign exchange reserves are on the rise, inflation has been essentially eliminated, and extreme poverty has fallen from 38% to 15%, a 23-point drop. Interim government 2019–2020 During the 2019 elections, the Transmisión de Resultados Electorales Preliminares (TREP) (a quick count process used in Latin America as a transparency measure in electoral processes) was interrupted; at the time, Morales had a lead of 46.86 percent to Mesa's 36.72, after 95.63 percent of tally sheets were counted. Two days after the interruption, the official count showed Morales fractionally clearing the 10-point margin he needed to avoid a runoff election, with the final official tally counted as 47.08 percent to Mesa's 36.51 percent, starting a wave of protests and tension in the country. Amidst allegations of fraud perpetrated by the Morales government, widespread protests were organized to dispute the election. On 10 November, the Organization of American States (OAS) released a preliminary report concluding several irregularities in the election, though these findings were heavily disputed. The New York Times reported on 7 June 2020 that the OAS analysis immediately after the 20 October election was flawed yet fuelled "a chain of events that changed the South American nation's history". After weeks of protests, Morales resigned on national television shortly after the Commander-in-Chief of the armed forces General Williams Kaliman had urged that he do so to restore "peace and stability". Opposition Senator Jeanine Áñez's declared herself interim president, claiming constitutional succession after the president, vice president and both head of the legislature chambers. She was confirmed as interim president by the constitutional court who declared her succession to be constitutional and automatic. International politicians, scholars and journalists are divided between describing the event as a coup or a spontaneous social uprising against an unconstitutional fourth term. Protests to reinstate Morales as president continued becoming highly violent: burning public buses and private houses, destroying public infrastructure and harming pedestrians. The protests were met with more violence by security forces against Morales supporters after Áñez exempted police and military from criminal responsibility in operations for "the restoration of order and public stability". In April 2020, the interim government took out a loan of more than $327 million from the International Monetary Fund to meet the country's needs during the COVID-19 pandemic. New elections were scheduled for 3 May 2020. In response to the coronavirus pandemic, the Bolivian electoral body, the TSE, made an announcement postponing the election. MAS reluctantly agreed with the first delay only. A date for the new election was delayed twice more, in the face of massive protests and violence. The final proposed date for the elections was 18 October 2020. Observers from the OAS, UNIORE, and the UN all reported that they found no fraudulent actions in the 2020 elections. The general election had a record voter turnout of 88.4% and ended in a landslide win for MAS which took 55.1% of the votes compared to 28.8% for centrist former president Carlos Mesa. Both Mesa and Áñez conceded defeat. Government of Luis Arce: 2020–present On 8 November 2020, Luis Arce was sworn in as President of Bolivia alongside his Vice President David Choquehuanca. In February 2021, the Arce government returned an amount of around $351 million to the IMF. This comprised a loan of $327 million taken out by the interim government in April 2020 and interest of around $24 million. The government said it returned the loan to protect Bolivia's economic sovereignty and because the conditions attached to the loan were unacceptable. Geography Bolivia is located in the central zone of South America, between 57°26'–69°38'W and 9°38'–22°53'S. With an area of , Bolivia is the world's 28th-largest country, and the fifth largest country in South America, extending from the Central Andes through part of the Gran Chaco, Pantanal and as far as the Amazon. The geographic center of the country is the so-called Puerto Estrella ("Star Port") on the Río Grande, in Ñuflo de Chávez Province, Santa Cruz Department. The geography of the country exhibits a great variety of terrain and climates. Bolivia has a high level of biodiversity, considered one of the greatest in the world, as well as several ecoregions with ecological sub-units such as the Altiplano, tropical rainforests (including Amazon rainforest), dry valleys, and the Chiquitania, which is a tropical savanna. These areas feature enormous variations in altitude, from an elevation of above sea level in Nevado Sajama to nearly along the Paraguay River. Although a country of great geographic diversity, Bolivia has remained a landlocked country since the War of the Pacific. Puerto Suárez, San Matías and Puerto Quijarro are located in the Bolivian Pantanal. Bolivia can be divided into three physiographic regions: The Andean region in the southwest spans 28% of the national territory, extending over . This area is located above altitude and is located between two big Andean chains, the Cordillera Occidental ("Western Range") and the Cordillera Central ("Central Range"), with some of the highest spots in the Americas such as the Nevado Sajama, with an altitude of , and the Illimani, at . Also located in the Cordillera Central is Lake Titicaca, the highest commercially navigable lake in the world and the largest lake in South America; the lake is shared with Peru. Also in this region are the Altiplano and the Salar de Uyuni, which is the largest salt flat in the world and an important source of lithium. The Sub-Andean region in the center and south of the country is an intermediate region between the Altiplano and the eastern llanos (plain); this region comprises 13% of the territory of Bolivia, extending over , and encompassing the Bolivian valleys and the Yungas region. It is distinguished by its farming activities and its temperate climate. The Llanos region in the northeast comprises 59% of the territory, with . It is located to the north of the Cordillera Central and extends from the Andean foothills to the Paraguay River. It is a region of flat land and small plateaus, all covered by extensive rain forests containing enormous biodiversity. The region is below above sea level. Geology The geology of Bolivia comprises a variety of different lithologies as well as tectonic and sedimentary environments. On a synoptic scale, geological units coincide with topographical units. Most elementally, the country is divided into a mountainous western area affected by the subduction processes in the Pacific and an eastern lowlands of stable platforms and shields. Climate The climate of Bolivia varies drastically from one eco-region to the other, from the tropics in the eastern llanos to a polar climate in the western Andes. The summers are warm, humid in the east and dry in the west, with rains that often modify temperatures, humidity, winds, atmospheric pressure and evaporation, yielding very different climates in different areas. When the climatological phenomenon known as El Niño takes place, it causes great alterations in the weather. Winters are very cold in the west, and it snows in the mountain ranges, while in the western regions, windy days are more common. The autumn is dry in the non-tropical regions. Llanos. A humid tropical climate with an average temperature of . The wind coming from the Amazon rainforest causes significant rainfall. In May, there is low precipitation because of dry winds, and most days have clear skies. Even so, winds from the south, called surazos, can bring cooler temperatures lasting several days. Altiplano. Desert-Polar climates, with strong and cold winds. The average temperature ranges from 15 to 20 °C. At night, temperatures descend drastically to slightly above 0 °C, while during the day, the weather is dry and solar radiation is high. Ground frosts occur every month, and snow is frequent. Valleys and Yungas. Temperate climate. The humid northeastern winds are pushed to the mountains, making this region very humid and rainy. Temperatures are cooler at higher elevations. Snow occurs at altitudes of . Chaco. Subtropical semi-arid climate. Rainy and humid in January and the rest of the year, with warm days and cold nights. Issues with climate change Bolivia is especially vulnerable to the negative consequences of climate change. Twenty percent of the world's tropical glaciers are located within the country, and are more sensitive to change in temperature due to the tropical climate they are located in. Temperatures in the Andes increased by 0.1 °C per decade from 1939 to 1998, and more recently the rate of increase has tripled (to 0.33 °C per decade from 1980 to 2005), causing glaciers to recede at an accelerated pace and create unforeseen water shortages in Andean agricultural towns. Farmers have taken to temporary city jobs when there is poor yield for their crops, while others have started permanently leaving the agricultural sector and are migrating to nearby towns for other forms of work; some view these migrants as the first generation of climate refugees. Cities that are neighbouring agricultural land, like El Alto, face the challenge of providing services to the influx of new migrants; because there is no alternative water source, the city's water source is now being constricted. Bolivia's government and other agencies have acknowledged the need to instill new policies battling the effects of climate change. The World Bank has provided funding through the Climate Investment Funds (CIF) and are using the Pilot Program for Climate Resilience (PPCR II) to construct new irrigation systems, protect riverbanks and basins, and work on building water resources with the help of indigenous communities. Biodiversity Bolivia, with an enormous variety of organisms and ecosystems, is part of the "Like-Minded Megadiverse Countries". Bolivia's variable altitudes, ranging from above sea level, allow for a vast biologic diversity. The territory of Bolivia comprises four types of biomes, 32 ecological regions, and 199 ecosystems. Within this geographic area there are several natural parks and reserves such as the Noel Kempff Mercado National Park, the Madidi National Park, the Tunari National Park, the Eduardo Avaroa Andean Fauna National Reserve, and the Kaa-Iya del Gran Chaco National Park and Integrated Management Natural Area, among others. Bolivia boasts over 17,000 species of seed plants, including over 1,200 species of fern, 1,500 species of marchantiophyta and moss, and at least 800 species of fungus. In addition, there are more than 3,000 species of medicinal plants. Bolivia is considered the place of origin for such species as peppers and chili peppers, peanuts, the common beans, yucca, and several species of palm. Bolivia also naturally produces over 4,000 kinds of potatoes. The country had a 2018 Forest Landscape Integrity Index mean score of 8.47/10, ranking it 21st globally out of 172 countries. Bolivia has more than 2,900 animal species, including 398 mammals, over 1,400 birds (about 14% of birds known in the world, being the sixth most diverse country in terms of bird species), 204 amphibians, 277 reptiles, and 635 fish, all fresh water fish as Bolivia is a landlocked country. In addition, there are more than 3,000 types of butterfly, and more than 60 domestic animals. In 2020 a new species of snake, the Mountain Fer-De-Lance Viper, was discovered in Bolivia. Environmental policy A Ministry of Environment and Water was created in 2006 after the election of Evo Morales, who reversed the privatization of the water distribution sector in the 1990s by President Gonzalo Sánchez de Lozada. The new Constitution, approved by referendum in 2009, makes access to water a fundamental right. In July 2010, at the initiative of Bolivia, the United Nations passed a resolution recognizing as "fundamental" the "right to safe and clean drinking water." Bolivia has gained global attention for its 'Law of the Rights of Mother Earth', which accords nature the same rights as humans. Government and politics Bolivia has been governed by democratically elected governments since 1982; prior to that, it was governed by various dictatorships. Presidents Hernán Siles Zuazo (1982–85) and Víctor Paz Estenssoro (1985–89) began a tradition of ceding power peacefully which has continued, although three presidents have stepped down in the face of extraordinary circumstances: Gonzalo Sánchez de Lozada in 2003, Carlos Mesa in 2005, and Evo Morales in 2019. Bolivia's multiparty democracy has seen a wide variety of parties in the presidency and parliament, although the Revolutionary Nationalist Movement, Nationalist Democratic Action, and the Revolutionary Left Movement predominated from 1985 to 2005. On 11 November 2019, all senior governmental positions were vacated following the resignation of Evo Morales and his government. On 13 November 2019, Jeanine Áñez, a former senator representing Beni, declared herself acting President of Bolivia. Luis Arce was elected on 23 October 2020; he took office as president on 8 November 2020. The constitution, drafted in 2006–07 and approved in 2009, provides for balanced executive, legislative, judicial, and electoral powers, as well as several levels of autonomy. The traditionally strong executive branch tends to overshadow the Congress, whose role is generally limited to debating and approving legislation initiated by the executive. The judiciary, consisting of the Supreme Court and departmental and lower courts, has long been riddled with corruption and inefficiency. Through revisions to the constitution in 1994, and subsequent laws, the government has initiated potentially far-reaching reforms in the judicial system as well as increasing decentralizing powers to departments, municipalities, and indigenous territories. The executive branch is headed by a president and vice president, and consists of a variable number (currently, 20) of government ministries. The president is elected to a five-year term by popular vote, and governs from the Presidential Palace (popularly called the Burnt Palace, ) in La Paz. In the case that no candidate receives an absolute majority of the popular vote or more than 40% of the vote with an advantage of more than 10% over the second-place finisher, a run-off is to be held among the two candidates most voted. The Asamblea Legislativa Plurinacional (Plurinational Legislative Assembly or National Congress) has two chambers. The (Chamber of Deputies) has 130 members elected to five-year terms, 63 from single-member districts (circunscripciones), 60 by proportional representation, and seven by the minority indigenous peoples of seven departments. The Cámara de Senadores (Chamber of Senators) has 36 members (four per department). Members of the Assembly are elected to five-year terms. The body has its headquarters on the Plaza Murillo in La Paz, but also holds honorary sessions elsewhere in Bolivia. The Vice President serves as titular head of the combined Assembly. The judiciary consists of the Supreme Court of Justice, the Plurinational Constitutional Court, the Judiciary Council, Agrarian and Environmental Court, and District (departmental) and lower courts. In October 2011, Bolivia held its first judicial elections to choose members of the national courts by popular vote, a reform brought about by Evo Morales. The Plurinational Electoral Organ is an independent branch of government which replaced the National Electoral Court in 2010. The branch consists of the Supreme Electoral Courts, the nine Departmental Electoral Court, Electoral Judges, the anonymously selected Juries at Election Tables, and Electoral Notaries. Wilfredo Ovando presides over the seven-member Supreme Electoral Court. Its operations are mandated by the Constitution and regulated by the Electoral Regime Law (Law 026, passed 2010). The Organ's first elections were the country's first judicial election in October 2011, and five municipal special elections held in 2011. Capital Bolivia has its constitutionally recognized capital in Sucre, while La Paz is the seat of government. La Plata (now Sucre) was proclaimed the provisional capital of the newly independent Alto Perú (later, Bolivia) on 1 July 1826. On 12 July 1839, President José Miguel de Velasco proclaimed a law naming the city as the capital of Bolivia, and renaming it in honor of the revolutionary leader Antonio José de Sucre. The Bolivian seat of government moved to La Paz at the start of the twentieth century as a consequence of Sucre's relative remoteness from economic activity after the decline of Potosí and its silver industry and of the Liberal Party in the War of 1899. The 2009 Constitution assigns the role of national capital to Sucre, not referring to La Paz in the text. In addition to being the constitutional capital, the Supreme Court of Bolivia is located in Sucre, making it the judicial capital. Nonetheless, the Palacio Quemado (the Presidential Palace and seat of Bolivian executive power) is located in La Paz, as are the National Congress and Plurinational Electoral Organ. La Paz thus continues to be the seat of government. Foreign relations Despite losing its maritime coast, the so-called Litoral Department, after the War of the Pacific, Bolivia has historically maintained, as a state policy, a maritime claim to that part of Chile; the claim asks for sovereign access to the Pacific Ocean and its maritime space. The issue has also been presented before the Organization of American States; in 1979, the OAS passed the 426 Resolution, which declared that the Bolivian problem is a hemispheric problem. On 4 April 1884, a truce was signed with Chile, whereby Chile gave facilities of access to Bolivian products through Antofagasta, and freed the payment of export rights in the port of Arica. In October 1904, the Treaty of Peace and Friendship was signed, and Chile agreed to build a railway between Arica and La Paz, to improve access of Bolivian products to the ports. The Special Economical Zone for Bolivia in Ilo (ZEEBI) is a special economic area of of maritime coast, and a total extension of , called Mar Bolivia ("Sea Bolivia"), where Bolivia may maintain a free port near Ilo, Peru under its administration and operation for a period of 99 years starting in 1992; once that time has passed, all the construction and territory revert to the Peruvian government. Since 1964, Bolivia has had its own port facilities in the Bolivian Free Port in Rosario, Argentina. This port is located on the Paraná River, which is directly connected to the Atlantic Ocean. In 2018, Bolivia signed the UN treaty on the Prohibition of Nuclear Weapons. The dispute with Chile was taken to the International Court of Justice. The court ruled in support of the Chilean position, and declared that although Chile may have held talks about a Bolivian corridor to the sea, the country was not required to negotiate one or to surrender its territory. Military The Bolivian military comprises three branches: Ejército (Army), Naval (Navy) and Fuerza Aérea (Air Force). The Bolivian army has around 31,500 men. There are six military regions (regiones militares—RMs) in the army. The army is organized into ten divisions. Although it is landlocked Bolivia keeps a navy. The Bolivian Naval Force (Fuerza Naval Boliviana in Spanish) is a naval force about 5,000 strong in 2008. The Bolivian Air Force ('Fuerza Aérea Boliviana' or "FAB") has nine air bases, located at La Paz, Cochabamba, Santa Cruz, Puerto Suárez, Tarija, Villamontes, Cobija, Riberalta, and Roboré. Law and crime There are 54 prisons in Bolivia, which incarcerate around 8,700 people . The prisons are managed by the Penitentiary Regime Directorate (). There are 17 prisons in departmental capital cities and 36 provincial prisons. Administrative divisions Bolivia has nine departments—Pando, La Paz, Beni, Oruro, Cochabamba, Santa Cruz, Potosí, Chuquisaca, Tarija. According to what is established by the Bolivian Political Constitution, the Law of Autonomies and Decentralization regulates the procedure for the elaboration of Statutes of Autonomy, the transfer and distribution of direct competences between the central government and the autonomous entities. There are four levels of decentralization: 1) Departmental government is constituted by the Departmental Assembly, with rights over the legislation of the department. The department governor is chosen by universal suffrage. 2) Municipal government is constituted by a Municipal Council which is responsible for legislation of the municipality. The municipality's mayor is chosen by universal suffrage. 3) Regional government is formed by several provinces or municipalities of geographical continuity within a department. It is constituted by a Regional Assembly. 4) Original indigenous government is constituted by self-governance of original indigenous people on the ancient territories where they live. While Bolivia's administrative divisions have similar status under governmental jurisprudence, each department varies in quantitative and qualitative factors. Generally speaking, Departments can be grouped either by geography or by political-cultural orientation. For example, Santa Cruz, Beni and Pando make up the low-lying "Camba" heartlands of the Amazon, Moxos and Chiquitanía. When considering political orientation, Beni, Pando, Santa Cruz, Tarija are generally grouped for regionalist autonomy movements; this region is known as the "Media Luna". Conversely, La Paz, Oruro, Potosí, Cochabamba have been traditionally associated with Andean politics and culture. Today, Chuquisaca vacillates between the Andean cultural bloc and the Camba bloc. Economy Driven largely by its natural resources Bolivia has become a region leader in measures of economic growth, fiscal stability and foreign reserves, although it remains a historically poor country. Bolivia's estimated 2012 gross domestic product (GDP) totaled $27.43 billion at official exchange rate and $56.14 billion at purchasing power parity. Despite a series of mostly political setbacks, between 2006 and 2009 the Morales administration spurred growth higher than at any point in the preceding 30 years. The growth was accompanied by a moderate decrease in inequality. Under Morales, per capita GDP doubled from US$1,182 in 2006 to US$2,238 in 2012. GDP growth under Morales averaged 5 percent a year, and in 2014 only Panama and the Dominican Republic performed better in all of Latin America. Bolivia's nominal GDP increased from 11.5 billion in 2006 to 41 billion in 2019. Bolivia in 2016 boasted the highest proportional rate of financial reserves of any nation in the world, with Bolivia's rainy day fund totaling some US$15 billion or nearly two-thirds of total annual GDP, up from a fifth of GDP in 2005. Even the IMF was impressed by Morales' fiscal prudence. Agriculture Agriculture is less relevant in the country's GDP compared to the rest of Latin America. The country produces close to 10 million tons of sugarcane per year and is the 10th largest producer of soybean in the world. It also has considerable yields of maize, potato, sorghum, banana, rice, and wheat. The country's largest exports are based on soy (soybean meal and soybean oil). The culture of soy was brought by Brazilians to the country: in 2006, almost 50% of soy producers in Bolivia were people from Brazil, or descendants of Brazilians. The first Brazilian producers began to arrive in the country in the 1990s. Before that, there was a lot of land in the country that was not used, or where only subsistence agriculture was practiced. Bolivia's most lucrative agricultural product continues to be coca, of which Bolivia is currently the world's third largest cultivator. Mineral resources Bolivia, while historically renowned for its vast mineral wealth, is relatively under-explored in geological and mineralogical terms. The country is rich in various mineral and natural resources, sitting at the heart of South America in the Central Andes. Mining is a major sector of the economy, with most of the country's exports being dependent on it. In 2019, the country was the eighth largest world producer of silver; fifth largest world producer of tin and antimony; seventh largest producer of zinc, eighth largest producer of lead, fourth largest world producer of boron; and the sixth largest world producer of tungsten. The country also has considerable gold production, which varies close to 25 tons/year, and also has amethyst extraction. Bolivia has the world's largest lithium reserves, second largest antimony reserves, third largest iron ore reserves, sixth largest tin reserves, ninth largest lead, silver, and copper reserves, tenth largest zinc reserves, and undisclosed but productive reserves of gold and tungsten. Additionally, there is believed to be considerable reserves of uranium and nickel present in the country's largely under-explored eastern regions. Diamond reserves may also be present in some formations of the Serranías Chiquitanas in Santa Cruz Department. Bolivia has the second largest natural gas reserves in South America. Its natural gas exports bring in millions of dollars per day, in royalties, rents, and taxes. From 2007 to 2017, what is referred to as the "government take" on gas totaled approximately $22 billion. The government held a binding referendum in 2005 on the Hydrocarbon Law. Among other provisions, the law requires that companies sell their production to the state hydrocarbons company Yacimientos Petroliferos Fiscales Bolivianos (YPFB) and for domestic demand to be met before exporting hydrocarbons and increased the state's royalties from natural gas. The passage of the Hydrocarbon law in opposition to then-President Carlos Mesa can be understood as part of the Bolivian gas conflict which ultimately resulted in election of Evo Morales, Bolivia's first indigenous president. The US Geological Service estimates that Bolivia has 21 million tonnes of lithium, which represent at least 25% of world reserves – the largest in the world. However, to mine for it would involve disturbing the country's salt flats (called Salar de Uyuni), an important natural feature which boosts tourism in the region. The government does not want to destroy this unique natural landscape to meet the rising world demand for lithium. On the other hand, sustainable extraction of lithium is attempted by the government. This project is carried out by the public company "Recursos Evaporíticos" subsidiary of COMIBOL. Tourism The income from tourism has become increasingly important. Bolivia's tourist industry has placed an emphasis on attracting ethnic diversity. The most visited places include Nevado Sajama, Torotoro National Park, Madidi National Park, Tiwanaku and the city of La Paz. The best known of the various festivals found in the country is the "Carnaval de Oruro", which was among the first 19 "Masterpieces of the Oral and Intangible Heritage of Humanity", as proclaimed by UNESCO in May 2001. Transport Roads Bolivia's Yungas Road was called the "world's most dangerous road" by the Inter-American Development Bank, called () in Spanish. The northern portion of the road, much of it unpaved and without guardrails, was cut into the Cordillera Oriental Mountain in the 1930s. The fall from the narrow path is as much as in some places and due to the humid weather from the Amazon there are often poor conditions like mudslides and falling rocks. Each year over 25,000 bikers cycle along the road. In 2018, an Israeli woman was killed by a falling rock while cycling on the road. The Apolo road goes deep into La Paz. Roads in this area were originally built to allow access to mines located near Charazani. Other noteworthy roads run to Coroico, Sorata, the Zongo Valley (Illimani mountain), and along the Cochabamba highway (). According to researchers with the Center for International Forestry Research (CIFOR), Bolivia's road network was still underdeveloped as of 2014. In lowland areas of Bolivia there is less than of paved road. There have been some recent investments; animal husbandry has expanded in Guayaramerín, which might be due to a new road connecting Guayaramerín with Trinidad. The country only opened its first duplicated highway in 2015: a 203 km stretch between the capital La Paz and Oruro. Air The General Directorate of Civil Aeronautics (Dirección General de Aeronáutica Civil—DGAC) formerly part of the FAB, administers a civil aeronautics school called the National Institute of Civil Aeronautics (Instituto Nacional de Aeronáutica Civil—INAC), and two commercial air transport services TAM and TAB. TAM – Transporte Aéreo Militar (the Bolivian Military Airline) was an airline based in La Paz, Bolivia. It was the civilian wing of the 'Fuerza Aérea Boliviana' (the Bolivian Air Force), operating passenger services to remote towns and communities in the North and Northeast of Bolivia. TAM (a.k.a. TAM Group 71) has been a part of the FAB since 1945. The airline company has suspended its operations since 23 September 2019. Boliviana de Aviación, often referred to as simply BoA, is the flag carrier airline of Bolivia and is wholly owned by the country's government. A private airline serving regional destinations is Línea Aérea Amaszonas, with services including some international destinations. Although a civil transport airline, TAB – Transportes Aéreos Bolivianos, was created as a subsidiary company of the FAB in 1977. It is subordinate to the Air Transport Management (Gerencia de Transportes Aéreos) and is headed by an FAB general. TAB, a charter heavy cargo airline, links Bolivia with most countries of the Western Hemisphere; its inventory includes a fleet of Hercules C130 aircraft. TAB is headquartered adjacent to El Alto International Airport. TAB flies to Miami and Houston, with a stop in Panama. The three largest, and main international airports in Bolivia are El Alto International Airport in La Paz, Viru Viru International Airport in Santa Cruz, and Jorge Wilstermann International Airport in Cochabamba. There are regional airports in other cities that connect to these three hubs. Technology Bolivia owns a communications satellite which was offshored/outsourced and launched by China, named Túpac Katari 1. In 2015, it was announced that electrical power advancements include a planned $300 million nuclear reactor developed by the Russian nuclear company Rosatom. Bolivia was ranked 97th in the Global Innovation Index in 2023, up from 110th in 2019. Water supply and sanitation Bolivia's drinking water and sanitation coverage has greatly improved since 1990 due to a considerable increase in sectoral investment. However, the country has the continent's lowest coverage levels and services are of low quality. Political and institutional instability have contributed to the weakening of the sector's institutions at the national and local levels. Two concessions to foreign private companies in two of the three largest cities – Cochabamba and La Paz/El Alto – were prematurely ended in 2000 and 2006 respectively. The country's second largest city, Santa Cruz de la Sierra, manages its own water and sanitation system relatively successfully by way of cooperatives. The government of Evo Morales intends to strengthen citizen participation within the sector. Increasing coverage requires a substantial increase of investment financing. According to the government the main problems in the sector are low access to sanitation throughout the country; low access to water in rural areas; insufficient and ineffective investments; a low visibility of community service providers; a lack of respect of indigenous customs; "technical and institutional difficulties in the design and implementation of projects"; a lack of capacity to operate and maintain infrastructure; an institutional framework that is "not consistent with the political change in the country"; "ambiguities in the social participation schemes"; a reduction in the quantity and quality of water due to climate change; pollution and a lack of integrated water resources management; and the lack of policies and programs for the reuse of wastewater. Only 27% of the population has access to improved sanitation, 80 to 88% has access to improved water sources. Coverage in urban areas is bigger than in rural ones. Some regions of Bolivia are largely under the power of the ganaderos, the large cattle and pig owners, and many small farmers are still reduced to peons. Nevertheless, the presence of the state has been clearly reinforced under the government of Evo Morales. The government tends to accommodate the interests of large landowners while trying to improve the living and working conditions of small farmers. Agriculture The agrarian reform promised by Evo Morales – and approved in a referendum by nearly 80 per cent of the population – has never been implemented. Intended to abolish latifundism by reducing the maximum size of properties that do not have an "economic and social function" to 5,000 hectares, with the remainder to be distributed among small agricultural workers and landless indigenous people, it was strongly opposed by the Bolivian oligarchy. In 2009, the government gave in to the agribusiness sector, which in return committed to end the pressure it was exerting and jeopardizing until the new constitution was in place. However, a series of economic reforms and projects have improved the condition of modest peasant families. They received farm machinery, tractors, fertilizers, seeds and breeding stock, while the state built irrigation systems, roads and bridges to make it easier for them to sell their produce in the markets. The situation of many indigenous people and small farmers was regularized through the granting of land titles for the land they were using. In 2007, the government created a "Bank for Productive Development" through which small workers and agricultural producers can borrow easily, at low rates and with repayment terms adapted to agricultural cycles. As a result of improved banking supervision, borrowing rates have been reduced by a factor of three between 2014 and 2019 across all banking institutions for small and medium-sized agricultural producers. In addition, the law now requires banks to devote at least 60% of their resources to productive credits or to the construction of social housing. With the creation of the Food Production Support Enterprise (Emapa), the government sought to stabilize the domestic market for agricultural products by buying the best prices for the production of small and medium-sized farmers, thus forcing agribusinesses to offer them fairer remuneration. According to Vice President Àlvaro García Linera, "by setting the rules of the game, the State establishes a new balance of power that gives more power to small producers. Wealth is better redistributed to balance the power of the agribusiness sector. This generates stability, which allows the economy to flourish and benefits everyone. Demographics According to the last two censuses carried out by the Bolivian National Statistics Institute (Instituto Nacional de Estadística, INE), the population increased from 8,274,325 (from which 4,123,850 were men and 4,150,475 were women) in 2001 to 10,059,856 in 2012. In the last fifty years the Bolivian population has tripled, reaching a population growth rate of 2.25%. The growth of the population in the inter-census periods (1950–1976 and 1976–1992) was approximately 2.05%, while between the last period, 1992–2001, it reached 2.74% annually. Some 67.49% of Bolivians live in urban areas, while the remaining 32.51% in rural areas. The most part of the population (70%) is concentrated in the departments of La Paz, Santa Cruz and Cochabamba. In the Andean Altiplano region the departments of La Paz and Oruro hold the largest percentage of population, in the valley region the largest percentage is held by the departments of Cochabamba and Chuquisaca, while in the Llanos region by Santa Cruz and Beni. At national level, the population density is 8.49, with variations marked between 0.8 (Pando Department) and 26.2 (Cochabamba Department). The largest population center is located in the so-called "central axis" and in the Llanos region. Bolivia has a young population. According to the 2011 census, 59% of the population is between 15 and 59 years old, 39% is less than 15 years old. Almost 60% of the population is younger than 25 years of age. Ethnic groups The vast majority of Bolivians are mestizo (with the indigenous component higher than the European one), although the government has not included the cultural self-identification "mestizo" in the November 2012 census. There are approximately three dozen native groups totaling approximately half of the Bolivian population – the largest proportion of indigenous people in the Americas. A 2018 estimate of racial classification put mestizo (mixed white and Amerindian) at 68%, indigenous at 20%, white at 5%, cholo at 2%, black at 1%, other at 4%, while 2% were unspecified; 44% attributed themselves to some indigenous group, predominantly the linguistic categories of Quechuas or Aymaras. White Bolivians comprised about 14% of the population in 2006, and are usually concentrated in the largest cities: La Paz, Santa Cruz de la Sierra and Cochabamba, but as well in some minor cities like Tarija and Sucre. The ancestry of whites and the white ancestry of mestizos lies within Europe and the Middle East, most notably Spain, Italy, Germany, Croatia, Lebanon and Syria. In the Santa Cruz Department, there are several dozen colonies of German-speaking Mennonites from Russia totaling around 40,000 inhabitants (). Afro-Bolivians, descendants of African slaves who arrived in the time of the Spanish Empire, inhabit the department of La Paz, and are located mainly in the provinces of Nor Yungas and Sud Yungas. Slavery was abolished in Bolivia in 1831. There are also important communities of Japanese (14,000) and Lebanese (12,900). Indigenous peoples, also called "originarios" ("native" or "original") and less frequently, Amerindians, could be categorized by geographic area, such as Andean, like the Aymaras and Quechuas (who formed the ancient Inca Empire), who are concentrated in the western departments of La Paz, Potosí, Oruro, Cochabamba and Chuquisaca. There also are ethnic populations in the east, composed of the Chiquitano, Chané, Guaraní and Moxos, among others, who inhabit the departments of Santa Cruz, Beni, Tarija and Pando. There are small numbers of European citizens from Germany, France, Italy and Portugal, as well as from other countries of the Americas, as Argentina, Brazil, Chile, Colombia, Cuba, Ecuador, the United States, Paraguay, Peru, Mexico and Venezuela, among others. There are important Peruvian colonies in La Paz, El Alto and Santa Cruz de la Sierra. There are around 140,000 Mennonites in Bolivia of Friesian, Flemish and German ethnic origins. Language Bolivia has great linguistic diversity as a result of its multiculturalism. The Constitution of Bolivia recognizes 36 official languages besides Spanish: Aymara, Araona, Baure, Bésiro, Canichana, Cavineño, Cayubaba, Chácobo, Chimán, Ese Ejja, Guaraní, Guarasu'we, Guarayu, Itonama, Leco, Machajuyai-Kallawaya, Machineri, Maropa, Mojeño-Ignaciano, Mojeño-Trinitario, Moré, Mosetén, Movima, Pacawara, Puquina, Quechua, Sirionó, Tacana, Tapieté, Toromona, Uru-Chipaya, Weenhayek, Yaminawa, Yuki, Yuracaré, and Zamuco. Spanish is the most spoken official language in the country, according to the 2001 census; as it is spoken by two-thirds of the population. All legal and official documents issued by the State, including the Constitution, the main private and public institutions, the media, and commercial activities, are in Spanish. The main indigenous languages are: Quechua (21.2% of the population in the 2001 census), Aymara (14.6%), Guarani (0.6%) and others (0.4%) including the Moxos in the department of Beni. Plautdietsch, a German dialect, is spoken by about 70,000 Mennonites in Santa Cruz. Portuguese is spoken mainly in the areas close to Brazil. Bilingual education was implemented in Bolivia under the leadership of President Evo Morales. His program placed emphasis on the expansion of indigenous languages in the educational systems of the country. Religion Bolivia is a constitutionally secular state that guarantees the freedom of religion and the independence of government from religion. According to the 2001 census conducted by the National Institute of Statistics of Bolivia, 78% of the population is Roman Catholic, followed by 19% that are Protestant, as well as a small number of Bolivians that are Orthodox, and 3% non-religious. The Association of Religion Data Archives (relying on the World Christian Database) records that in 2010, 92.5% of Bolivians identified as Christian (of any denomination), 3.1% identified with indigenous religion, 2.2% identified as Baháʼí, 1.9% identified as agnostic, and all other groups constituted 0.1% or less. Much of the indigenous population adheres to different traditional beliefs marked by inculturation or syncretism with Christianity. The cult of Pachamama, or "Mother Earth", is notable. The veneration of the Virgin of Copacabana, Virgin of Urkupiña and Virgin of Socavón, is also an important feature of Christian pilgrimage. There also are important Aymaran communities near Lake Titicaca that have a strong devotion to James the Apostle. Deities worshiped in Bolivia include Ekeko, the Aymaran god of abundance and prosperity, whose day is celebrated every 24 January, and Tupá, a god of the Guaraní people. Largest cities and towns Approximately 67% of Bolivians live in urban areas, among the lowest proportion in South America. Nevertheless, the rate of urbanization is growing steadily, at around 2.5% annually. According to the 2012 census, there are total of 3,158,691 households in Bolivia – an increase of 887,960 from 2001. In 2009, 75.4% of homes were classified as a house, hut, or Pahuichi; 3.3% were apartments; 21.1% were rental residences; and 0.1% were mobile homes. Most of the country's largest cities are located in the highlands of the west and central regions. Culture Bolivian culture has been heavily influenced by the Spanish, the Aymara, the Quechua, as well as the popular cultures of Latin America as a whole. The cultural development is divided into three distinct periods: precolumbian, colonial, and republican. Important archaeological ruins, gold and silver ornaments, stone monuments, ceramics, and weavings remain from several important pre-Columbian cultures. Major ruins include Tiwanaku, El Fuerte de Samaipata, Inkallaqta and Iskanwaya. The country abounds in other sites that are difficult to reach and have seen little archaeological exploration. The Spanish brought their own tradition of religious art which, in the hands of local native and mestizo builders and artisans, developed into a rich and distinctive style of architecture, painting, and sculpture known as "Mestizo Baroque". The colonial period produced not only the paintings of Pérez de Holguín, Flores, Bitti, and others but also the works of skilled but unknown stonecutters, woodcarvers, goldsmiths, and silversmiths. An important body of Native Baroque religious music of the colonial period was recovered and has been performed internationally to wide acclaim since 1994. Bolivian artists of stature in the 20th century include María Luisa Pacheco, Roberto Mamani Mamani, Alejandro Mario Yllanes, Alfredo Da Silva, and Marina Núñez del Prado. Bolivia has a rich folklore. Its regional folk music is distinctive and varied. The "devil dances" at the annual carnival of Oruro are one of the great folkloric events of South America, as is the lesser known carnival at Tarabuco. Education In 2008, following UNESCO standards, Bolivia was declared free of illiteracy, making it the fourth country in South America to attain this status. Bolivia has public and private universities. Among them: Universidad Mayor, Real y Pontificia de San Francisco Xavier de Chuquisaca USFX – Sucre, founded in 1624; Universidad Mayor de San Andrés UMSA – La Paz, founded in 1830; Universidad Mayor de San Simon UMSS – Cochabamba, founded in 1832; Universidad Autónoma Gabriel René Moreno UAGRM – Santa Cruz de la Sierra, founded in 1880; Universidad Técnica de Oruro UTO – Oruro, founded in 1892; Universidad Evangélica Boliviana UEB – Santa Cruz de la Sierra, founded in 1980; and Universidad Autónoma Tomás Frías UATF – Potosi, founded in 1892. Health According to UNICEF under-five mortality rate in 2006 was 52.7 per 1000 and was reduced to 26 per 1000 by 2019. The infant mortality rate was 40.7 per 1000 in 2006 and was reduced to 21.2 per 1000 in 2019. Before Morales took office, nearly half of all infants were not vaccinated; now nearly all are vaccinated. Morales also put into place several supplemental nutrition programs, including an effort to supply free food in public health and social security offices, and his desnutrición cero (zero malnutrition) program provides free school lunches. Between 2006 and 2016, extreme poverty in Bolivia fell from 38.2% to 16.8%. Chronic malnutrition in children under five years of age also went down by 14% and the child mortality rate was reduced by more than 50%, according to World Health Organization. In 2019 the Bolivian government created a universal healthcare system which has been cited as a model for all by the World Health Organization. Women's rights With the election of Evo Morales to the presidency in 2005, "chola" or "cholitas" women, who had long been despised, gained new rights and social recognition. More generally, the 2009 Constitution improves the rights of Bolivian women. Despite a 2013 law against violence against women, a decade later Bolivia is the Latin American country with the highest rate of femicide. Thanks to a quota policy, by 2022 Bolivia will be the second country in the world, after Rwanda, to have as many women parliamentarians (52% in the Legislative Assembly and 47% in the Chamber of Senators). Sports Football is popular. The national team is the Bolivia national football team. Racquetball is the second most popular sport in Bolivia as for the results in the Odesur 2018 Games held in Cochabamba. Bolivia has won 13 medals at the Pan American Games and 10 of them came from racquetball events, including their only gold medal won in the Men's Team event in 2019. Basketball is especially popular and influential in the Potosí Department.

Botswana

Botswana (; , ), officially the Republic of Botswana (, ), is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 per cent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. It is connected by the Kazungula Bridge to Zambia, across the world's shortest border between two countries. A country of slightly over 2.3 million people, Botswana is one of the most sparsely populated countries in the world. It is essentially the nation state of the Tswana, who make up 79% of the population. About 11.6 per cent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—it has since transformed itself into an upper-middle-income country, with one of the world's fastest-growing economies. Modern-day humans first inhabited the country over 200,000 years ago. The Tswana ethnic group were descended mainly from Bantu-speaking tribes who migrated southward of Africa to modern Botswana around 600 AD, living in tribal enclaves as farmers and herders. In 1885, the British colonised the area and declared a protectorate under the name of Bechuanaland. As decolonisation occurred, Bechuanaland became an independent Commonwealth republic under its current name on 30 September 1966. Since then, it has been a representative republic, with a consistent record of uninterrupted democratic elections and the lowest perceived corruption ranking in Africa since at least 1998. The economy is dominated by mining and tourism. Botswana has a GDP (purchasing power parity) per capita of about $18,113 , one of the highest in the subsaharan Africa. Botswana is the world's biggest diamond producing country. Its relatively high gross national income per capita (by some estimates the fourth-largest in Africa) gives the country a relatively high standard of living and the third-highest Human Development Index of continental Sub-Saharan Africa (after Gabon and South Africa). Botswana is the first African country to host Forbes 30 Under 30 and the 2017 Netball World Youth Cup. Botswana is a member of the Southern African Customs Union, the Southern African Development Community, the Commonwealth of Nations, and the United Nations. The country has been adversely affected by the HIV/AIDS epidemic. In 2002, Botswana became the first country to offer anti-retroviral drugs (ARVs) to help combat the epidemic. Despite the launch of programs to make treatment available and to educate the populace about the epidemic, the number of people with AIDS rose from 290,000 in 2005 to 320,000 in 2013. , Botswana had the third-highest prevalence rate for HIV/AIDS, with roughly 20% of the population infected. However, in recent years the country has made strides in combatting HIV/AIDS, with efforts being made to provide proper treatment and lower the rate of mother-to-child transmission. Etymology The country's name means "Land of the Tswana", referring to the dominant ethnic group in Botswana. The Constitution of Botswana recognizes a homogeneous Tswana state. The term Batswana was originally applied to the Tswana, which is still the case. However, it has also come to be used generally as a demonym for all citizens of Botswana. History Early history Archaeological digs demonstrate that hominids lived in Botswana for around two million years. Stone tools and fauna remains have shown that all areas of the country were inhabited at least 400,000 years ago. In October 2019, researchers reported that Botswana was the birthplace of all modern humans about 200,000 years ago. Evidence left by modern humans, such as cave paintings, is about 73,000 years old. The earliest known inhabitants of southern Africa are thought to have been the forebears of present-day San ("Bushmen") and Khoi peoples. Both groups speak click languages from the small Khoe-Kwadi, Kx’a and Tuu families whose members hunted, gathered, and traded over long distances. When cattle were first introduced about 2000 years ago into southern Africa, pastoralism became a major feature of the economy, since the region had large grasslands free of tsetse flies. It is unclear when Bantu-speaking peoples first moved into the country from the north, although AD 600 seems to be a consensus estimate. In that era the ancestors of the modern-day Kalanga moved into what is now the north-eastern areas of the country. These proto-Kalanga were closely connected to states in Zimbabwe as well as to the Mapungubwe state and the notable of these was Domboshaba ruins, a cultural and heritage site in Botswana originally occupied towards the end of the Great Zimbabwe period (1250–1450 AD), with stone walls that have an average height of 1.8 metres. The site is a respected place for the people living in the region and it is believed that the chief lived on the top of the hill together with his helpers or assistants. These states, located outside of current Botswana's borders, appear to have kept massive herds of cattle in what is now the Central District—apparently at numbers approaching modern cattle density. This massive cattle-raising complex prospered until 1300 AD or so and seems to have regressed following the collapse of Mapungubwe. During this era the first Tswana-speaking groups, the Bakgalagadi, moved into the southern areas of the Kalahari. All these various peoples were connected to trade routes that ran via the Limpopo River to the Indian Ocean, and trade goods from Asia such as beads made their way to Botswana, most likely in exchange for ivory, gold and rhinoceros horn. Toutswemogala Hill Iron Age Settlement's radio-carbon dates for this settlement range from 7th to late 19th century AD indicating occupation of more than one thousand years. The hill was part of the formation of early states in Southern Africa with cattle keeping as major source of economy. Toutswe settlement include house-floors, large heaps of vitrified cow-dung and burials while the outstanding structure is the stone wall. There are large tracts of centaurs ciliaris, a type of grass which has come to be associated with cattle-keeping settlements in South, Central Africa. Around 700 A.D., the Toutswe people moved westward into Botswana and began an agricultural and pastoral land tenure system based on sorghum and millet, and domesticated stock, respectively. The site was situated in the centre of a broader cultural area in Eastern Botswana and shares many commonalities with other archaeological sites of this region, in both ceramic production styles and also time frames inhabited. Large structures were observed that contained vitrified remains of animal dung, leading to the theory that these were animal enclosures and that Toutswemogala Hill was thus a major centre of animal husbandry in the region. However, agriculture also played a vital role in the longevity of Toutswemogala Hill's extended occupation, as many grain storage structures have also been found on the site. Many different stratified layers of housing floors further signal continuous occupation over hundreds of years. The arrival of the ancestors of the Tswana-speakers who came to control the region has yet to be dated precisely. Members of the Bakwena, a chieftaincy under a legendary leader named Kgabo II, made their way into the southern Kalahari by AD 1500, at the latest, and his people drove the Bakgalagadi inhabitants west into the desert. Over the years, several offshoots of the Bakwena moved into adjoining territories. The Bangwaketse occupied areas to the west, while the Bangwato moved northeast into formerly Kalanga areas. Not long afterwards, a Bangwato offshoot known as the Batawana migrated into the Okavango Delta, probably in the 1790s. Effects of the Mfecane and Batswana-Boer Wars The first written records relating to modern-day Botswana appear in 1824. What these records show is that the Bangwaketse had become the predominant power in the region. Under the rule of Makaba II, the Bangwaketse kept vast herds of cattle in well-protected desert areas, and used their military prowess to raid their neighbours. Other chiefdoms in the area, by this time, had capitals of 10,000 or so and were fairly prosperous. This equilibrium came to end during the Mfecane period, 1823–1843, when a succession of invading peoples from South Africa entered the country. Although the Bangwaketse were able to defeat the invading Bakololo in 1826, over time all the major chiefdoms in Botswana were attacked, weakened, and impoverished. The Bakololo and AmaNdebele raided repeatedly and took large numbers of cattle, women, and children from the Batswana—most of whom were driven into the desert or sanctuary areas such as hilltops and caves. Only after 1843, when the Amandebele moved into western Zimbabwe, did this threat subside. During the 1840s and 1850s trade with Cape Colony-based merchants opened up and enabled the Batswana chiefdoms to rebuild. The Bakwena, Bangwaketse, Bangwato and Batawana cooperated to control the lucrative ivory trade and then used the proceeds to import horses and guns, which in turn enabled them to establish control over what is now Botswana. This process was largely complete by 1880, and thus the Bushmen, the Kalanga, the Bakgalagadi, and other current minorities were subjugated by the Batswana. The earliest known map of Botswana dates from 1849, drawn by David Livingstone. Following the Great Trek, Afrikaners from the Cape Colony established themselves on the borders of Botswana in the Transvaal. In 1852 a coalition of Tswana chiefdoms led by Sechele I defeated Afrikaner incursions at the Battle of Dimawe and, after about eight years of intermittent tensions and hostilities, eventually came to a peace agreement in Potchefstroom in 1860. From that point on, the modern-day border between South Africa and Botswana was agreed on, and the Afrikaners and Batswana traded and worked together comparatively peacefully. In 1884 Batawana, a northern based Tswana clan's cavalry under the command of Kgosi Moremi fought and defeated the Ndebele's invasion of northern Botswana at the Battle of Khutiyabasadi. This blow to the larger invading Ndebele force signalled the start of the collapse of the Ndebele Kingdom in Zimbabwe and helped galvanise Tswana speaking authority of the area now making part of northern Botswana. Due to newly peaceful conditions, trade thrived between 1860 and 1880. Taking advantage of this were Christian missionaries. The Lutherans and the London Missionary Society both became established in the country by 1856. By 1880, every major village had a resident missionary, and their influence slowly became felt. Khama III (reigned 1875–1923) was the first of the Tswana chiefs to make Christianity a state religion and changed a great deal of Tswana customary law as a result. Christianity became the de facto official religion in all the chiefdoms by World War I. Colonialism and the Bechuanaland Protectorate During the Scramble for Africa the territory of Botswana was coveted by both the German Empire and Britain. During the Berlin Conference, Britain decided to annex Botswana in order to safeguard the Road to the North and thus connect the Cape Colony to its territories further north. It unilaterally annexed Tswana territories in January 1885 and then sent the Warren Expedition north to consolidate control over the area and convince the chiefs to accept British overrule. Despite their misgivings, they eventually acquiesced to this fait accompli. In 1890 areas north of 22 degrees were added to the new Bechuanaland Protectorate. During the 1890s the new territory was divided into eight different reserves, with fairly small amounts of land being left as freehold for white settlers. During the early 1890s, the British government decided to hand over the Bechuanaland Protectorate to the British South Africa Company. This plan, which was well on its way to fruition despite the entreaties of Tswana leaders who toured England in protest, was eventually foiled by the failure of the Jameson Raid in January 1896. When the Union of South Africa was formed in 1910 from the main British colonies in the region, the High Commission Territories—the Bechuanaland Protectorate, Basutoland (now Lesotho), and Swaziland (now Eswatini)—were not included, but provision was made for their later incorporation. However, the UK began to consult with their inhabitants as to their wishes. Although successive South African governments sought to have the territories transferred to their jurisdiction, the UK kept delaying; subsequently, it never occurred. The election of the Nationalist government in 1948, which instituted apartheid, and South Africa's withdrawal from the Commonwealth in 1961, ended any prospect of the UK or these territories agreeing to incorporation into South Africa. An expansion of British central authority and the evolution of native government resulted in the 1920 establishment of two advisory councils to represent both Africans and Europeans. The African Council consisted of the eight heads of the Tswana tribes and some elected members. Proclamations in 1934 regulated tribal rule and powers. A European-African advisory council was formed in 1951, and the 1961 constitution established a consultative legislative council. Independence In June 1964, the United Kingdom accepted proposals for a democratic self-government in Botswana. An independence conference was held in London in February 1966. The seat of government was moved in 1965 from Mahikeng in South Africa, to the newly established Gaborone, which is located near Botswana's border with South Africa. Based on the 1965 constitution, the country held its first general elections under universal suffrage and gained independence on 30 September 1966. Seretse Khama, a leader in the independence movement and the legitimate claimant to the Ngwato chiefship, was elected as the first president, and subsequently re-elected twice. Queen Elizabeth II, accompanied by Prince Philip, Duke of Edinburgh and her son Prince Andrew, Duke of York, arrived in Botswana during the fourth-leg tour of Africa on 25–27 July 1979. During their visit, they were greeted by tribal dancers and a 21-gun salute. Khama died in office in 1980. The presidency passed to the sitting vice-president, Quett Masire, who was elected in his own right in 1984 and re-elected in 1989 and 1994. Masire retired from office in 1998. He was succeeded by Festus Mogae, who was elected in his own right in 1999 and re-elected in 2004. The presidency passed in 2008 to Ian Khama (son of the first president), who had been serving as Mogae's vice-president since resigning his position in 1998 as Commander of the Botswana Defence Force to take up this civilian role. On 1 April 2018 Mokgweetsi Eric Keabetswe Masisi was sworn in as the fifth president of Botswana, succeeding Ian Khama. He represents the Botswana Democratic Party, which has also won a majority in every parliamentary election since independence. All the previous presidents have also represented the same party. A long-running dispute over the northern border with Namibia's Caprivi Strip was the subject of a ruling by the International Court of Justice in December 1999. It ruled that Kasikili Island belongs to Botswana. In 2014, the Okavango Delta of Botswana, the largest inland delta in the world, was inscribed as the 1000th World Heritage Site. In the 1970s, Botswana held a reputation of being one the world's principal producers of diamonds. This reputation has held into the modern day as Botswana's diamond mining industry is among the world's largest. Botswana's Jwaneng mine in particular is the world's richest. Geography At Botswana is the world's 48th-largest country. It is similar in size to Madagascar or France. It lies between latitudes 17° and 27° south, and longitudes 20° and 30° east. Botswana is predominantly flat, tending towards gently rolling tableland. Botswana is dominated by the Kalahari Desert, which covers up to 70% of its land surface. The Okavango Delta, one of the world's largest inland river deltas, is in the north-west. The Makgadikgadi Pan, a large salt pan, lies in the north. The Limpopo River Basin, the major landform of all of southern Africa, lies partly in Botswana, with the basins of its tributaries, the Notwane, Bonwapitse, Mahalapye, Lotsane, Motloutse and the Shashe, located in the eastern part of the country. The Notwane provides water to the capital through the Gaborone Dam. The Chobe River lies to the north, providing a boundary between Botswana and Namibia's Zambezi Region. The Chobe River meets with the Zambezi River at a place called Kazungula (meaning a small sausage tree, a point where Sebitwane and his Makololo tribe crossed the Zambezi into Zambia). Biodiversity and conservation Botswana has diverse areas of wildlife habitat. In addition to the delta and desert areas, there are grasslands and savannas, where blue wildebeest, antelopes, and other mammals and birds are found. Northern Botswana has one of the few remaining large populations of the endangered African wild dog. Chobe National Park, found in the Chobe District, has the world's largest concentration of African elephants. The park covers about and supports about 350 species of birds. The Chobe National Park and Moremi Game Reserve (in the Okavango Delta) are major tourist destinations. Other reserves include the Central Kalahari Game Reserve located in the Kalahari Desert in Ghanzi District; Makgadikgadi Pans National Park and Nxai Pan National Park are in Central District in the Makgadikgadi Pan. Mashatu Game Reserve is privately owned, located at the confluence of the Shashe and Limpopo Rivers in eastern Botswana. The other privately owned reserve is Mokolodi Nature Reserve near Gaborone. There are also specialised sanctuaries like Khama Rhino Sanctuary (for rhinoceros) and Makgadikgadi Sanctuary (for flamingos). They are both located in Central District. Botswana faces two major environmental problems, drought and desertification, which are heavily linked. Three-quarters of the country's human and animal populations depend on groundwater due to drought. Groundwater use through deep borehole drilling has somewhat eased the effects of drought. Surface water is scarce in Botswana and less than 5% of the agriculture in the country is sustainable by rainfall. In the remaining 95% of the country, raising livestock is the primary source of rural income. Approximately 71% of the country's land is used for communal grazing, which has been a major cause of the desertification and the accelerating soil erosion of the country. Since raising livestock has been profitable for the people of Botswana, they continue to exploit the land with dramatically increasing numbers of animals. From 1966 to 1991, the livestock population grew from 1.7 million to 5.5 million. Similarly, the human population has increased from 574,000 in 1971 to 1.5 million in 1995, a 161% increase in 24 years. Over 50% of all households in Botswana own cattle, which is currently the largest single source of rural income. Rangeland degradation or desertification is regarded as the reduction in land productivity as a result of overstocking and overgrazing, or as a result of veld product gathering for commercial use. Degradation is exacerbated by the effects of drought and climate change. Environmentalists report that the Okavango Delta is drying up due to the increased grazing of livestock. The Okavango Delta is one of the major semi-forested wetlands in Botswana and one of the largest inland deltas in the world; it is a crucial ecosystem to the survival of many animals. The Department of Forestry and Range Resources has already begun to implement a project to reintroduce indigenous vegetation into communities in Kgalagadi South, Kweneng North and Boteti. Reintroduction of indigenous vegetation will help reduce the degradation of the land. The United States Government has also entered into an agreement with Botswana, giving them US$7 million to reduce Botswana's debt by US$8.3 million. The stipulation of the US reducing Botswana's debt is that Botswana will focus on more extensive conservation of the land. The country had a 2018 Forest Landscape Integrity Index mean score of 9.13/10, ranking it 8th globally out of 172 countries. The United Nations Development Programme claims that poverty is a major problem behind the overexploitation of resources, including land, in Botswana. To help change this the UNDP joined in with a project started in the southern community of Struizendam in Botswana. The purpose of the project is to draw from "indigenous knowledge and traditional land management systems". The leaders of this movement are supposed to be the people in the community, to draw them in, in turn increasing their possibilities to earn an income and thus decreasing poverty. The UNDP also stated that the government has to effectively implement policies to allow people to manage their own local resources and are giving the government information to help with policy development. Government and politics Botswana is a parliamentary republic governed by the Constitution of Botswana, and it is the longest uninterrupted democracy in Africa. Its seat of government is in Gaborone. Botswana's governing institutions were established after it became an independent nation in 1966. Botswana's governmental structure is based on both the Westminster system of the United Kingdom and the tribal governments of the Tswana people. Botswana has a centralised government in which national law supersedes local law. Local laws are developed by local councils and district councils. They are heavily influenced by tribal governments, which are led by the tribe's chief. The Parliament of Botswana consists of the National Assembly, which serves as the nation's formal legislature, and the Ntlo ya Dikgosi, an advisory body made up of tribal chiefs and other appointed members. Botswana's executive branch is led by the President of Botswana, who serves as both the head of state and head of government. The members of parliament choose the president, and the president then appoints the Vice-President and the members of the Cabinet. The president has significant power in Botswana, and the legislature has little power to check the president once appointed. The judiciary includes the High Court of Botswana, the Court of Appeal, and Magistrates' Courts. Cases are often settled by customary courts with tribal chiefs presiding. Elections in Botswana are held every five years and overseen by the Independent Electoral Commission (IEC). Botswana operates a multi-party system in which many political parties compete in elections, but it is effectually a dominant-party state in which the Botswana Democratic Party has ruled with a majority government since independence. The nation's elections are recognised as free and fair, but the ruling party has institutional advantages that other parties do not. Factionalism is common within Botswana's political parties, and several groups have formed new parties by splitting from established ones. Since 2019, the Umbrella for Democratic Change has operated as a coalition of opposition parties. The most recent election was held in 2019, with the Botswana Democratic Party maintaining its majority and Mokgweetsi Masisi being re-elected president. In Botswana's early years, its politics were managed by President Seretse Khama and Vice-President (later president) Quett Masire. Since the Kgabo Commission in 1991, factionalism and political rivalries have dominated Batswana politics. The Barata-Phathi faction was led by Peter Mmusi, Daniel Kwelagobe, and Ponatshego Kedikilwe, while the A-Team faction was led by Mompati Merafhe and Jacob Nkate. When Festus Mogae and Ian Khama became president and vice-president, respectively, they aligned with the A-Team. Khama effectively expelled the A-Team from the party in 2010 after he became president. A new rivalry formed in 2018 when Khama's chosen successor, Mokgweetsi Masisi, became president. He opposed Khama, and the two formed a political rivalry that looms over Batswana politics in the 2020s. Foreign relations and military At the time of independence, Botswana had no armed forces. It was only after the Rhodesian and South African armies attacked the Zimbabwe People's Revolutionary Army and Umkhonto we Sizwe bases respectively that the Botswana Defence Force (BDF) was formed in 1977. The president is commander-in-chief of the armed forces and appoints a defence council and the BDF currently consists of roughly 60,000 servicemen. In 2019, Botswana signed the UN treaty on the Prohibition of Nuclear Weapons. Following political changes in South Africa and the region, the BDF's missions have increasingly focused on prevention of poaching, preparing for disasters, and foreign peacekeeping. The United States has been the largest single foreign contributor to the development of the BDF, and a large segment of its officer corps have received U.S. training. The Botswana government gave the United States permission to explore the possibility of establishing an Africa Command (AFRICOM) base in the country. Human rights Many of the indigenous San people have been forcibly relocated from their land to reservations. To make them relocate, they were denied access to water on their land and faced arrest if they hunted, which was their primary source of food. Their lands lie in the middle of the world's richest diamond field. Officially, the government denies that there is any link to mining and claims the relocation is to preserve the wildlife and ecosystem, even though the San people have lived sustainably on the land for millennia. On the reservations they struggle to find employment, and alcoholism is rampant. On 24 August 2018 the UN Special Rapporteur on Minorities, Fernand de Varennes, issued a statement calling on Botswana "to step up efforts to recognise and protect the rights of minorities in relation to public services, land and resource use and the use of minority languages in education and other critical areas." Botswana was ranked as a "flawed democracy" and 30th out of 167 states in the 2021 Democracy Index (The Economist), higher than Italy and Belgium, and just below the Czech Republic. This was the second highest rating in Africa, and highest ranking in continental Africa (only the offshore island nation of Mauritius bested its ranking). According to 2023 V-Dem Democracy indices Botswana ranks as 75th electoral democracy worldwide and 12th electoral democracy in Africa. According to Transparency International, Botswana is the least corrupt country in Africa and ranks just below Portugal and South Korea. Until June 2019, homosexual acts were illegal in Botswana. A Botswana High Court decision of 11 June of that year struck down provisions in the Criminal Code that punished "carnal knowledge of any person against the order of nature" and "acts of gross indecency", making Botswana one of twenty-two African countries that have either decriminalised or legalised homosexual acts. Capital punishment is a legal penalty for murder in Botswana, and executions are carried out by hanging. The Botswana Centre for Human Rights, Ditshwanelo, was established in 1993. Administrative divisions Botswana's ten districts are: Southern District South-East District Kweneng District Kgatleng District Central District North-East District Ngamiland District Kgalagadi District Chobe District Ghanzi District Botswana's councils created from urban or town councils are: Gaborone City, Francistown, Lobatse Town, Selebi-Phikwe Town, Jwaneng Town, Orapa Town and Sowa Township. Economy Since independence, Botswana has had one of the fastest growth rates in per capita income in the world. Botswana has transformed itself from one of the poorest countries in the world to an upper middle-income country. GDP per capita grew from $1,344 in 1950 to $15,015 in 2016. Although Botswana was resource-abundant, a good institutional framework allowed the country to reinvest resource-income in order to generate stable future income. By one estimate, it has the fourth highest gross national income at purchasing power parity in Africa, giving it a standard of living around that of Mexico. The Ministry of Trade and Industry of Botswana is responsible for promoting business development throughout the country. According to the International Monetary Fund, economic growth averaged over 9% per year from 1966 to 1999. Botswana has a high level of economic freedom compared to other African countries. The government has maintained a sound fiscal policy, despite consecutive budget deficits in 2002 and 2003, and a negligible level of foreign debt. It earned the highest sovereign credit rating in Africa and has stockpiled foreign exchange reserves (over $7 billion in 2005/2006) amounting to almost two and a half years of current imports. The constitution provides for an independent judiciary, and the government respects this in practice. The legal system is sufficient to conduct secure commercial dealings, although a serious and growing backlog of cases prevents timely trials. The protection of intellectual property rights has improved significantly. Botswana is ranked second only to South Africa among sub-Saharan Africa countries in the 2014 International Property Rights Index. While generally open to foreign participation in its economy, Botswana reserves some sectors for citizens. Increased foreign investment plays a significant role in the privatisation of state-owned enterprises. Investment regulations are transparent, and bureaucratic procedures are streamlined and open, although somewhat slow. Investment returns such as profits and dividends, debt service, capital gains, returns on intellectual property, royalties, franchise's fees, and service fees can be repatriated without limits. Botswana imports refined petroleum products and electricity from South Africa. There is some domestic production of electricity from coal. Energy Transport During SONA 2020 summit it was announced that Botswana has a network of roads, of varied quality and capacity, totalling about . Of these, are paved (this is including of motorways. The remaining worth are unpaved. Road distances are shown in kilometers and speed limits are indicated in kilometers per hour (kph) or by the use of the national speed limit (NSL) symbol. Some vehicle categories have various lower maximum limits enforced by speed limits, for example trucks. Finance An array of financial institutions populates the country's financial system, with pension funds and commercial banks being the two most important segments by asset size. Banks remain profitable, well-capitalised, and liquid, as a result of growing national resources and high interest rates. The Bank of Botswana serves as a central bank. The country's currency is the Botswana pula. Botswana's competitive banking system is one of Africa's most advanced. Generally adhering to global standards in the transparency of financial policies and banking supervision, the financial sector provides ample access to credit for entrepreneurs. The Capital Bank opened in 2008. , there are a dozen licensed banks in the country. The government is involved in banking through state-owned financial institutions and a special financial incentives programme that is aimed at increasing Botswana's status as a financial centre. Credit is allocated on market terms, although the government provides subsidised loans. Reform of non-bank financial institutions has continued in recent years, notably through the establishment of a single financial regulatory agency that provides more effective supervision. The government has abolished exchange controls, and with the resulting creation of new portfolio investment options, the Botswana Stock Exchange is growing. Gemstones and precious metals In Botswana, the Department of Mines and Mineral Resources, Green Technology and Energy Security led by Hon Sadique Kebonang in Gaborone, maintains data regarding mining throughout the country. Debswana, the largest diamond mining company operating in Botswana, is 50% owned by the government. The mineral industry provides about 40% of all government revenues. In 2007, significant quantities of uranium were discovered, and mining was projected to begin by 2010. Several international mining corporations have established regional headquarters in Botswana, and prospected for diamonds, gold, uranium, copper, and even oil, many coming back with positive results. Government announced in early 2009 that they would try to shift their economic dependence on diamonds, over serious concern that diamonds are predicted to dry out in Botswana over the next twenty years. Botswana's Orapa mine is the largest diamond mine in the world in terms of value and quantity of carats produced annually. Estimated to have produced over 11 million carats in 2013, with an average price of $145/carat, the Orapa mine was estimated to produce over $1.6 billion worth of diamonds in 2013. Creative industries Increasing importance is being given to the economic contribution of the creative industries to national economies. The United Nations Conference on Trade and Development (UNCTAD) recompiles statistics about the export and import of goods and services related to the creative industries. The World Intellectual Property Organization (WIPO) has assisted in the preparation of national studies measuring the size of over 50 copyright industries around the world. According to the WIPO compiled data, the national contribution of creative industries varies from 2% to 11% depending on the country. Using the WIPO-framework, the Companies and Intellectual Property Authority(CIPA) and the Botswana Institute for Development Policy Analysis were published by a sector-specific study in 2019. In 2016, copyright industries contributed 5.46% to value-added and 2.66% to the total labour force, 1.28% to exports, and 3.47% to imports. Demographics As of 2012, the Tswana are the majority ethnic group in Botswana, making up approximately 79% of the population, followed by Kalanga at 11% and the San (Basarwa) at 3%. The remaining 7% is made up of White Batswana/European Batswana, Indians, and a number of other smaller Southern African ethnic groups. Native groups include the Bayei, Bambukushu, Basubia, Baherero and Bakgalagadi. The Indian minority is made up of both recent migrants and descendants of Indian migrants who arrived from Mozambique, Kenya, Tanzania, Mauritius and South Africa. Since 2000, because of deteriorating economic conditions in Zimbabwe, the number of Zimbabweans in Botswana has risen into the tens of thousands. Fewer than 10,000 San people are still living their traditional hunter-gatherer way of life. Since the mid-1990s the central government of Botswana has been trying to move San out of their historic lands. James Anaya, as the Special Rapporteur on the situation of human rights and fundamental freedoms of indigenous people for the United Nations in 2010, described loss of land as a major contributor to many of the problems facing Botswana's indigenous people, citing the San's eviction from the Central Kalahari Game Reserve (CKGR) as a special example. Among Anaya's recommendations in a report to the United Nations Human Rights Council was that development programs should promote, in consultation with indigenous communities such as the San and Bakgalagadi people, activities in harmony with the culture of those communities such as traditional hunting and gathering activities. Languages The official language of Botswana is English, while Setswana is widely spoken across the country. In Setswana, prefixes are more important than they are in many other languages, since Setswana is a Bantu language and has noun classes denoted by these prefixes. They include Bo, which refers to the country, Ba, which refers to the people, Mo, which is one person, and Se which is the language. For example, the main ethnic group of Botswana is the Tswana people, hence the name Botswana for its country. The people as a whole are Batswana, one person is a Motswana, and the language they speak is Setswana. Other languages spoken in Botswana include Kalanga (Sekalanga), Sarwa (Sesarwa), Ndebele, Kgalagadi, Tswapong, !Xóõ, Yeyi, and, in some parts, Afrikaans. Religion An estimated 77% of the country's citizens identify as Christians. Anglicans, Methodists, and the United Congregational Church of Southern Africa make up the majority of Christians. There are also congregations of Lutherans, Baptists, Roman Catholics, The Church of Jesus Christ of Latter-day Saints, the Dutch Reformed Church, Mennonites, Seventh-day Adventists, Jehovah's Witnesses and Serbian Orthodox in the country. According to the 2001 census, the nation has around 5,000 Muslims (mainly from South Asia), 3,000 Hindus, and 700 of the Baháʼí Faith. Approximately 20% of citizens identify with no religion. Culture Literature and cinema Botswana literature belongs somewhere in the strong African literary writing circles. African literature is known for its consciousness and didactic writing styles. Writing as an art form has existed in Botswana for a long while, from the rock painting era — especially in the Tsodilo Hills, known to be 20,000 years old — to the present day, with the movie production of The No.1 Ladies Detective Agency, based on a series of more than 20 novels set in Botswana. [[File:Unity Dow - PopTech 2011 - Camden Maine USA (cropped).jpg|thumb|left|Unity Dow, author of Far and Beyon''', The Screaming of the Innocent, and Heavens May Fall]] In recent times and to date Botswana has seen a remarkable appearance of distinguished writers whose genres range from historical, political and witty story writing. Prominent amongst these are the South African-born Bessie Head, who settled in Serowe; Andrew Sesinyi; Barolong Seboni (whose works include Images of the Sun, Screams and Pleas, Lovesongs, Windsongs of the Kgalagadi and Lighting the Fire, and several other publications that include a play, Sechele I, and Setswana Riddles Translated into English); Unity Dow, Galesiti Baruti; Caitlin Davies; Lauri Kubuetsile; Albert Malikongwa; Toro Mositi; and Moteane Melamu. Most of Bessie Head's important works are set in Serowe. When Rain Clouds Gather (1968), Maru (1971), and A Question of Power (1973) all have this setting. The three are also autobiographical; When Rain Clouds Gather is based on her experience living on a development farm, Maru incorporates her experience of being considered racially inferior, and A Question of Power draws on her understanding of what it was like to experience acute psychological distress. Head also published a number of short stories, including the collection The Collector of Treasures (1977). She published a book on the history of Serowe, Serowe: Village of the Rainwind. Her last novel, A Bewitched Crossroad (1984), is historical, set in 19th-century Botswana. She had also written a story of two prophets, one wealthy and one who lived poorly, called Jacob: The Faith-Healing Priest."Bessie Amelia Head, SA novelist dies", South African History Online, 17 April 1986. The 1981 comedy The Gods Must Be Crazy was set in Botswana and became a major international hit; 2000's Disney production Whispers: An Elephant's Tale was filmed in Botswana. In 2009, parts of M. Saravanan's Tamil-language Indian action film Ayan were filmed in Botswana. The critically acclaimed A United Kingdom, about the real-life love story of Seretse Khama and Ruth Williams, was filmed partly between Botswana and London, and was released internationally in 2016. Media There are six television stations in Botswana, one of which is state-owned (Botswana TV), along with Now TV, Khuduga HD, Maru TV, Access TV and EBotswana. There are five local radio stations (RB1, RB2, Duma FM, Gabz FM, and Yarona FM) and thirteen newspapers (Mmegi, Sunday Standard, The Telegraph, Business Weekly, The Botswana Gazette, The Voice, The Guardian, Echo, Botswana People's Daily, DailyNews, Tswana Times, Weekend Post, and The Monitor) that publish regularly. Music Botswana's music is mostly vocal and performed, sometimes without drums depending on the occasion; it also makes heavy use of string instruments. Botswana folk music has instruments such as setinkane (a sort of miniature piano), segankure/segaba (a Botswanan version of the Chinese instrument erhu), moropa (meropa -plural) (many varieties of drums), phala (a whistle used mostly during celebrations, which comes in a variety of forms). Botswanan cultural musical instruments are not confined only to the strings or drums. The hands are used as musical instruments too, by either clapping them together or against (goat skin turned inside out wrapped around the calf area, only used by men) to create music and rhythm. For the last few decades, the guitar has been celebrated as a versatile music instrument for Tswana music as it offers a variety in string which the segaba instrument does not have. The national anthem is "Fatshe leno la rona". Written and composed by Kgalemang Tumediso Motsete, it was adopted upon independence in 1966. Visual arts In the northern part of Botswana, women in the villages of Etsha and Gumare are noted for their skill at crafting baskets from Mokola Palm and local dyes. The baskets are generally woven into three types: large, lidded baskets used for storage, large, open baskets for carrying objects on the head or for winnowing threshed grain, and smaller plates for winnowing pounded grain. The artistry of these baskets is being steadily enhanced through colour use and improved designs as they are increasingly produced for international markets. The oldest paintings from both Botswana and South Africa depict hunting, animal and human figures, and were made by the Khoisan (!Kung San/Bushmen) over twenty thousand years ago within the Kalahari Desert. Food The cuisine of Botswana mostly includes meat as Botswana is a cattle country. The national dish is seswaa, pounded meat made from goat meat or beef, Segwapa dried, cured meat ranging from beef to game meats & the cut may also vary, either fillets of meat cut into strips following the grain of the muscle, or flat pieces sliced across the grain. Botswana's cuisine shares some characteristics with other cuisine of Southern Africa. Examples of Botswana food are: Bogobe, pap (maize porridge), boerewors, samp, Magwinya (fried dough bread) and mopane worms. Porridge (bogobe) is made by putting sorghum, maize, or millet flour into boiling water, stirring into a soft paste, and cooking it slowly. A dish called ting is made when the sorghum or maize is fermented and milk and sugar added. Without the milk and sugar, ting is sometimes eaten with meat or vegetables as lunch or dinner. Another way of making bogobe is to add sour milk and a cooking melon (lerotse). This dish is called tophi by the Kalanga tribe. Madila is a traditional fermented milk product similar to yogurt or sour cream. Many different kinds of beans are grown, including cowpeas, ditloo, and letlhodi. Some vegetables grow in the wild and are available seasonally including thepe and Delele (okra). Many fruits are locally available, including marula. Watermelons, believed to have come originally from Botswana, are plentiful in season. Another kind of melon, called lerotse or lekatane, is also grown. Some kinds of wild melon found in sandy desert areas are an important food and water source for the people who live in those areas. Kgalagadi Breweries Limited produces the national beer, St. Louis Lager, Botswana's first and only local beer brand that has also been a part of Botswana's rich history since 1989, and non-alcoholic beverage Keone Mooka Mageu, a traditional fermented porridge. Sports Football is the most popular sport in Botswana, with qualification for the 2012 Africa Cup of Nations being the national team's highest achievement to date. Other popular sports are softball, cricket, tennis, rugby, badminton, handball, golf, and track and field. Botswana is an associate member of the International Cricket Council. Botswana became a member of The International Badminton Federation and Africa Badminton Federation in 1991. The Botswana Golf Union has an amateur golf league in which golfers compete in tournaments and championships. Botswana won the country's first Olympic medal in 2012 when runner Nijel Amos won silver in the 800 metres. In 2011, Amantle Montsho became world champion in the 400 metres and won Botswana's first athletics medal at the world level. High jumper Kabelo Kgosiemang is a three-time African champion, Isaac Makwala is a sprinter who specialises in the 400 metres, he was the gold medalist at the Commonwealth Games in 2018, Baboloki Thebe was a silver medalist in the 200 metres at the 2014 Summer Youth Olympics and reached the semi-finals at the 2014 World Junior Championships in Athletics, and Ross Branch Ross, a motor-biker, holds the number one plate in the South African Cross Country Championship and has competed at the Dakar Rally. Letsile Tebogo set the world junior record in the 100 metres with a time of 9.94 at the 2022 World Athletics Championships. On 7 August 2021 Botswana won the bronze medal in the Men's 4 × 400 metres relay at the Olympics in Tokyo. The card game bridge has a strong following; it was first played in Botswana around 40 years ago, and it grew in popularity during the 1980s. Many British expatriate school teachers informally taught the game in Botswana's secondary schools. The Botswana Bridge Federation (BBF) was founded in 1988 and continues to organise tournaments. Bridge has remained popular and the BBF has over 800 members. In 2007, the BBF invited the English Bridge Union to host a week-long teaching programme in May 2008. Education Botswana has made great strides in educational development since independence in 1966. At that time there were very few graduates in the country and only a very small percentage of the population attended secondary school. Botswana increased its adult literacy rate from 69% in 1991 to 83% in 2008. Among sub-Saharan African countries, Botswana has one of the highest literacy rates. According to The World Factbook - Central Intelligence Agency as of 2015, 88.5% of the population age 15 and over could read and write and were respectively literate. With the discovery of diamonds and the increase in government revenue that this brought, there was a huge increase in educational provision in the country. All students were guaranteed ten years of basic education, leading to a Junior Certificate qualification. Approximately half of the school population attends a further two years of secondary schooling leading to the award of the Botswana General Certificate of Secondary Education (BGCSE). Secondary education in Botswana is neither free nor compulsory. After leaving school, students can attend one of the seven technical colleges in the country, or take vocational training courses in teaching or nursing. Students enter the University of Botswana, Botswana University of Agriculture and Natural Resources, Botswana International University of Science and Technology and the Botswana Accountancy College in Gaborone. Many other students end up in the numerous private tertiary education colleges around the country. Notable among these is Botho University, the country's first private university which offers undergraduate programs in Accounting, Business and Computing. Another international university is the Limkokwing University of Creative Technology which offers various associate degrees in Creative Arts. Other tertiary institutions include Ba Isago, ABM University College the largest school of business and management, New Era, Gaborone Institute of Professional Studies, Gaborone University College of Law And Professional Studies etc. Tremendous strides in providing quality education have been made by private education providers such that a large number of the best students in the country are now applying to them as well. A vast majority of these students are government sponsored. The nation's second international university, the Botswana International University of Science and Technology, was completed in Palapye in 2011. The quantitative gains have not always been matched by qualitative ones. Primary schools in particular still lack resources, and the teachers are less well paid than their secondary school colleagues. The Botswana Ministry of Education is working to establish libraries in primary schools in partnership with the African Library Project. The Government of Botswana hopes that by investing a large part of national income in education, the country will become less dependent on diamonds for its economic survival, and less dependent on expatriates for its skilled workers. Those objectives are in part pursued through policies in favour of vocational education, gathered within the NPVET (National Policy on Vocational Education and Training), aiming to "integrate the different types of vocational education and training into one comprehensive system". Botswana invests 21% of its government spending in education. In January 2006, Botswana announced the reintroduction of school fees after two decades of free state education though the government still provides full scholarships with living expenses to any Botswana citizen in university, either at the University of Botswana or if the student wishes to pursue an education in any field not offered locally, they are provided with a full scholarship to study abroad. Science and technology Botswana is planning to use science and technology to diversify its economy and thereby reduce its dependence on diamond mining. To this end, the government has set up six hubs since 2008, in the agriculture, diamonds, innovation, transport, health and education sectors. Botswana published its updated National Policy on Research, Science and Technology in 2011, within a UNESCO project sponsored by the Spanish Agency for International Cooperation and Development (AECID). This policy aims to take up the challenges of rapid technological evolution, globalisation and the achievement of the national development goals formulated in high-level strategic documents that include Botswana's Tenth National Development Plan to 2016 and Vision 2016. The National Policy on Research, Science, Technology and Innovation (2011) fixes the target of raising gross domestic expenditure on research and development (R&D) from 0.26% of GDP in 2012 to over 2% of GDP by 2016. This target can only be reached within the specified time frame by raising public spending on R&D. Despite the modest level of financial investment in research, Botswana counts one of the highest researcher densities in sub-Saharan Africa: 344 per million inhabitants (in head counts), compared to an average of 91 per million inhabitants for the subcontinent in 2013. Botswana was ranked 85th in the Global Innovation Index in 2023. In 2009, Botswana-based company Deaftronics launched a solar-powered hearing aid after six years of prototype development. Since then, Deaftronics has sold over 10,000 of the hearing aids. Priced at $200 per unit, each hearing aid includes four rechargeable batteries (lasting up to three years) and a solar charger for them. The product is inexpensive compared to many similar devices, that can start from around $600. In 2011, Botswana's Department of Agricultural Research (DAR) unveiled Musi cattle, designed to ultimately optimise the overall efficiency for beef production under Botswana conditions. A hybrid of Tswana, Bonsmara, Brahman, Tuli and Simmental breeds, it is hoped that the composite will lead to increased beef production. The objective of the research was to find a genetic material that could perform like cross-breeds already found in Botswana and well above the indigenous Tswana breed while retaining the hardiness and adaptability of the native stock in one package. In 2016, the Botswana Institute of Technology Research and Innovation (BITRI) developed a rapid testing kit for foot-and-mouth disease in collaboration with the Botswana Vaccine Institute and Canadian Food Inspection Agency. The existing diagnostic methods required highly trained laboratory personnel and special equipment, which caused delays in the implementation of control procedures; whereas the kit developed in Botswana allows for on-site diagnosis to be made. The Square Kilometre Array (SKA) (MeerKAT) will consist of thousands of dishes and antennas spread over large distances linked together to form one giant telescope. Additional dishes will be located in eight other African countries Botswana among them. Botswana was selected to participate because of its ideal location in the southern hemisphere and environment, which could enable easier data collection from the universe. Botswana government has built SKA precursor telescope at Kgale View, called the African Very Long Base Line Interferometry Network (AVN) & sent student on Astronomy scholarships. Botswana launched its own 3-year programme to build & launch a Micro Satellite (CubeSat) Botswana Satellite Technology (Sat-1 Project) in Gaborone on 18 December 2020. The development of the satellite will be led by Botswana International University of Science and Technology (BIUST) with technical support from University of Oulu in Finland and Loon, a giant leap forward in the realisation of Botswana's ambition to become a technologically driven economy. The satellite, which will be used for earth observation, will generate data for smart farming and real-time virtual tourism. Furthermore, it will help us predict and forecast harvest time through the use of robotics and automated technology. In the IT sector in 2016 a firm, Almaz, opened a first-of-its-kind computer assembly company. Ditec, a Botswana company, also customises, designs and manufactures mobile phones. Ditec is one of the leading experts in design, development and customisation of Microsoft powered devices. On 19 November 2021 scientists at the Botswana Harvard HIV Reference Laboratory (BHHRL) first discovered the variant Omicron subsequently designated B.1.1.529, and then named "Omicron" becoming the first country in the world to discover the variant. Since early 2021, they have genome-sequenced some 2,300 positive SARS-CoV-2 virus samples. According to Dr Gaseitsiwe, Botswana's genome sequence submissions to GISAID are among the highest in the African region on a per capita basis, on a par with its well-resourced neighbour South Africa. Botswana Harvard AIDS Institute Partnership (BHP) was built in 2003, two years after the umbrella organisation opened the BHHRL, its purpose-built HIV research lab and one of the first on the continent. Infrastructure Botswana has of railway lines, of roads, and 92 airports, of which 12 have paved runways. The paved road network has almost entirely been constructed since independence in 1966. The national airline is Air Botswana, which flies domestically and to other countries in Africa. Botswana Railways is the national railway company, which forms a crucial link in the Southern African regional railway system. Botswana Railways offers rail-based transport facilities for moving a range of commodities for the mining sector and primary industries, as well as passenger-train services and dry ports. In terms of power infrastructure in Botswana, the country produces coal for electricity and oil is imported into the country. Recently, the country has taken a large interest in renewable energy sources and has completed a comprehensive strategy that will attract investors in the wind, solar and biomass renewable energy industries. Botswana's power stations include Morupule B Power Station (600 MW), Morupule A Power Station (132 MW), Orapa Power Station (90 MW), Phakalane Power Station (1.3 MW) and Mmamabula Power Station (300 MW), which is expected to be online in the near future. A 200 MW solar power plant is at the planning and design stage by Ministry of Mineral Resources, Green Technology and Energy Security.. Health Health industry The Ministry of Health in Botswana is responsible for overseeing the quality and distribution of healthcare throughout the country. Life expectancy at birth was 55 in 2009 according to the World Bank, having previously fallen from a peak of 64.1 in 1990 to a low of 49 in 2002. After Botswana's 2011 census, current life expectancy is estimated at 54.06 years. The Cancer Association of Botswana is a voluntary non-governmental organisation. The association is a member of the Union for International Cancer Control. The Association supplements existing services through provision of cancer prevention and health awareness programs, facilitating access to health services for cancer patients and offering support and counseling to those affected. HIV/AIDS epidemic Like elsewhere in Sub-Saharan Africa, the economic impact of AIDS is considerable. Economic development spending was cut by 10% in 2002–3 as a result of recurring budget deficits and rising expenditure on healthcare services. Botswana has been hit very hard by the AIDS pandemic; in 2006 it was estimated that life expectancy at birth had dropped from 65 to 35 years. However, after Botswana's 2011 census current life expectancy is estimated at 54.06 years. However the graph here shows over 65 years, therefore there is conflicting information about life expectancy. The prevalence of HIV/AIDS in Botswana was estimated at 25.4% for adults aged 15–49 in 2009 and 21.9% in 2013, exceeded by Lesotho and Eswatini in sub-Saharan African nations. This places Botswana at the third highest prevalence in the world, in 2013, while "leading the way in prevention and treatment programmes". In 2003, the government began a comprehensive programme involving free or cheap generic antiretroviral drugs as well as an information campaign designed to stop the spread of the virus; in 2013, over 40% of adults in Botswana had access to antiretroviral therapy. In the age group of 15–19 years old, prevalence was estimated at 6% for females and 3.5% for males in 2013, and for the 20–24 age group, 15% for females and 5% for males. Botswana is one of 21 priority countries identified by the UN AIDS group in 2011 in the Global Plan to eliminate new HIV infections among children and to keep their mothers alive. From 2009 to 2013, the country saw a decrease over 50% in new HIV infections in children. A further measure of the success, or reason for hope, in dealing with HIV in Botswana, is that less than 10% of pregnant HIV-infected women were not receiving antiretroviral medications in 2013, with a corresponding large decrease (over 50%) in the number of new HIV infections in children under 5. Among the UN Global Plan countries, people living with HIV in Botswana have the highest percentage receiving antiretroviral treatment: about 75% for adults (age 15+) and about 98% for children. With a nationwide Prevention of Mother-to-Child Transmission program, Botswana has reduced HIV transmission from infected mothers to their children from about 40% to just 4%. Under the leadership of Festus Mogae, the Government of Botswana solicited outside help in fighting HIV/AIDS and received early support from the Bill and Melinda Gates Foundation, the Merck Foundation, and together formed the African Comprehensive HIV/AIDS Partnership (ACHAP). Other early partners include the Botswana-Harvard AIDS Institute, of the Harvard School of Public Health and the Botswana-UPenn Partnership of the University of Pennsylvania. According to the 2011 UNAIDS Report, universal access to treatment – defined as 80% coverage or greater – has been achieved in Botswana. Tourism The Botswana Tourism Organisation is the country's official tourism group. Primarily, tourists visit Gaborone due to the city having numerous activities for visitors. The Lion Park Resort is Botswana's first permanent amusement park and hosts events such as birthday parties for families. Other destinations in Botswana include the Gaborone Yacht Club and the Kalahari Fishing Club and natural attractions such as the Gaborone Dam and Mokolodi Nature Reserve. There are golf courses which are maintained by the Botswana Golf Union (BGU). The Phakalane Golf Estate is a multi-million-dollar clubhouse that offers both hotel accommodations and access to golf courses. Museums in Botswana include: Botswana National Museum in Gaborone Kgosi Bathoen II (Segopotso) Museum in Kanye Kgosi Sechele I Museum in Molepolole Khama III Memorial Museum in Serowe Nhabe Museum in Maun Phuthadikobo Museum in Mochudi Supa Ngwano Museum Centre in Francistown See also Outline of Botswana List of Botswana-related topics Notes References Citations Bibliography General sources Further reading Charles, Thalefang (2016).

British Virgin Islands

The British Virgin Islands (BVI), officially the Virgin Islands, is a British Overseas Territory in the Caribbean, to the east of Puerto Rico and the US Virgin Islands and north-west of Anguilla. The islands are geographically part of the Virgin Islands archipelago and are located in the Leeward Islands of the Lesser Antilles and part of the West Indies. The British Virgin Islands consist of the main islands of Tortola, Virgin Gorda, Anegada and Jost Van Dyke, along with more than 50 other smaller islands and cays. About 16 of the islands are inhabited. The capital, Road Town, is on Tortola, the largest island, which is about long and wide. The islands had a population of 28,054 at the 2010 Census, of whom 23,491 lived on Tortola; current estimates put the population at 35,802 (July 2018). British Virgin Islanders are British Overseas Territories citizens and since 2002, are also British citizens. Etymology The islands were named "Santa Úrsula y las Once Mil Vírgenes" by Christopher Columbus in 1493 after the legend of Saint Ursula and the 11,000 virgins. The name was later shortened to "the Virgin Islands". The official name of the territory is still simply the "Virgin Islands", but the prefix "British" is often used. This is commonly believed to distinguish it from the neighbouring American territory which changed its name from the "Danish West Indies" to "Virgin Islands of the United States" in 1917. However, local historians have disputed this, pointing to a variety of publications and public records dating from between 21 February 1857 and 12 September 1919 where the territory is referred to as the British Virgin Islands. British Virgin Islands government publications continue to begin with the name "The territory of the Virgin Islands", and the territory's passports simply refer to the "Virgin Islands", and all laws begin with the words "Virgin Islands". Moreover, the territory's Constitutional Commission has expressed the view that "every effort should be made" to encourage the use of the name "Virgin Islands". But various public and quasi-public bodies continue to use the name "British Virgin Islands" or "BVI", including BVI Finance, BVI Electricity Corporation, BVI Tourist Board, BVI Athletic Association, BVI Bar Association and others. In 1968 the British Government issued a memorandum requiring that the postage stamps in the territory should say "British Virgin Islands" (whereas previously they had simply stated "Virgin Islands"), a practice which is still followed today. This was likely to prevent confusion following on from the adoption of US currency in the territory in 1959, and the references to US currency on the stamps of the territory. History It is generally thought that the Virgin Islands were first settled by the Arawak from South America around 100 BC to AD 200, though there is some evidence of Amerindian presence on the islands as far back as 1500 BC. The Arawaks inhabited the islands until the 15th century when they were displaced by the more aggressive Caribs, a tribe from the Lesser Antilles islands. The first European sighting of the Virgin Islands was by the Spanish expedition of Christopher Columbus in 1493 on his second voyage to the Americas, who gave the islands their modern name. The Spanish Empire claimed the islands by discovery in the early 16th century, but never settled them, and subsequent years saw the English, Dutch, French, Spanish, and Danish all jostling for control of the region, which became a notorious haunt for pirates. There is no record of any native Amerindian population in the British Virgin Islands during this period; it is thought that they either fled to safer islands or were killed. The Dutch established a permanent settlement on the island of Tortola by 1648, frequently clashing with the Spanish who were based on nearby Puerto Rico. In 1672, the English captured Tortola from the Dutch, and the English annexation of Anegada and Virgin Gorda followed in 1680. Meanwhile, over the period 1672–1733, the Danish gained control of the nearby islands of Saint Thomas, Saint John and Saint Croix (i.e. the modern US Virgin Islands). The British islands were considered principally a strategic possession. The British introduced sugar cane which was to become the main crop and source of foreign trade, and large numbers of slaves were forcibly brought from Africa to work on the sugar cane plantations. The islands prospered economically until the middle of the nineteenth century, when a combination of the abolition of slavery in the British Empire in 1834, a series of disastrous hurricanes, and the growth in the sugar beet crop in Europe and the United States significantly reduced sugar cane production and led to a period of economic decline. In 1917, the United States purchased the Danish Virgin Islands for US$25 million, renaming them the United States Virgin Islands. Economic linkages with the US islands prompted the British Virgin Islands to adopt the US dollar as its currency in 1959. The British Virgin Islands were administered variously as part of the British Leeward Islands or with St. Kitts and Nevis, with an administrator representing the British Government on the islands. The islands gained separate colony status in 1960 and became autonomous in 1967 under the new post of Chief Minister. Since the 1960s, the islands have diversified away from their traditionally agriculture-based economy towards tourism and financial services, becoming one of the wealthiest areas in the Caribbean. The constitution of the islands was amended in 1977, 2004 and 2007, giving them greater local autonomy. In 2017 Hurricane Irma struck the islands, causing four deaths and immense damage. Geography The British Virgin Islands comprise around 60 tropical Caribbean islands, ranging in size from the largest, Tortola, being long and wide, to tiny uninhabited islets, altogether about in extent. They are located in the Virgin Islands archipelago, a few miles east of the US Virgin Islands, and about from the Puerto Rican mainland. About east south-east lies Anguilla. The North Atlantic Ocean lies to the east of the islands, and the Caribbean Sea lies to the west. Most of the islands are volcanic in origin and have a hilly, rugged terrain. The highest point is Mount Sage on Tortola at 521m. Anegada is geologically distinct from the rest of the group, being a flat island composed of limestone and coral. The British Virgin Islands contain the Leeward Islands moist forests and Leeward Islands xeric scrub terrestrial ecoregions. Climate The British Virgin Islands have a tropical rainforest climate, moderated by trade winds. Temperatures vary little throughout the year. In the capital, Road Town, typical daily maxima are around in the summer and in the winter. Typical daily minima are around in the summer and in the winter. Rainfall averages about per year, higher in the hills and lower on the coast. Rainfall can be quite variable, but the wettest months on average are September to November and the driest months on average are February and March. Hurricanes Hurricanes occasionally hit the islands, with the Atlantic hurricane season running from June to November. Hurricane Irma On 6 September 2017, Hurricane Irma struck the islands, causing extensive damage, especially on Tortola, and killing four people. The Caribbean Disaster Emergency Management Agency declared a state of emergency. Visiting Tortola on 13 September 2017, UK Foreign Secretary Boris Johnson said that he was reminded of photos of Hiroshima after it had been hit by the atom bomb. By 8 September, the UK government sent troops with medical supplies and other aid. More troops were expected to arrive a day or two later, but , carrying more extensive assistance, was not expected to reach the islands for another two weeks. Entrepreneur Richard Branson, a resident of Necker Island, called on the UK government to develop a massive disaster recovery plan to include "both through short-term aid and long-term infrastructure spending". Premier Orlando Smith also called for a comprehensive aid package to rebuild the territory. On 10 September UK Prime Minister Theresa May pledged £32 million to the Caribbean for a hurricane relief fund and promised that the UK government would match donations from the public to the British Red Cross appeal. Specifics were not provided to the news media as to the amount that would be allocated to the Virgin Islands. Boris Johnson's visit to Tortola on 13 September 2017 during his Caribbean tour was intended to confirm the UK's commitment to helping restore British islands but he provided no additional comments on the aid package. He did confirm that HMS Ocean had departed for the BVI carrying items like timber, buckets, bottled water, food, baby milk, bedding and clothing, as well as ten pickup trucks, building materials and hardware. The UK offered to underwrite rebuilding loans up to US$400m as long as there was accountability as to how the monies were spent. Successive NDP and VIP governments declined, despite there having been created a Recovery & Development Authority led by highly skilled infrastructure personnel, many of whom were ex-military with decades of infrastructure rebuilding expertise from war zones and natural disaster sites. Many wealthy residents also proposed a large rebuilding plan, starting with key infrastructure, such as the high school. Nearly five years later, there was no sign of any such rebuilding of the high school or certain other key infrastructure. Politics The territory operates as a parliamentary democracy. Ultimate executive authority in the British Virgin Islands is vested in the King, and is exercised on his behalf by the Governor of the British Virgin Islands. The governor is appointed by the King on the advice of the British Government. Defence and most foreign affairs remain the responsibility of the United Kingdom. The most recent constitution was adopted in 2007 (the Virgin Islands Constitution Order, 2007) and came into force when the Legislative Council was dissolved for the 2007 general election. The head of government under the constitution is the Premier (before the new constitution the office was referred to as Chief Minister), who is elected in a general election along with the other members of the ruling government as well as the members of the opposition. Elections are held roughly every four years. A cabinet is nominated by the Premier and appointed and chaired by the Governor. The Legislature consists of the King (represented by the Governor) and a unicameral House of Assembly made up of 13 elected members plus the Speaker and the Attorney General. The current Governor is John Rankin (since 29 January 2020). The current Premier is Natalio Wheatley (since 5 May 2022), who is leader of the Virgin Islands Party. On 8 June 2022, subordinate UK legislation was made allowing for direct rule for the islands. However, the British Government decided on that date not to implement direct rule. Subdivisions The British Virgin Islands is a unitary territory. The territory is divided into nine electoral districts, and each voter is registered in one of those districts. Eight of the nine districts are partly or wholly on Tortola, and encompass nearby neighbouring islands. Only the ninth district (Virgin Gorda and Anegada) does not include any part of Tortola. At elections, in addition to voting their local representative, voters also cast votes for four "at-large" candidates who are elected upon a territory-wide basis. The territory is also technically divided into five administrative districts (one for each of the four largest islands, with the fifth covering all other islands), and into six civil registry districts (three for Tortola, Jost Van Dyke, Virgin Gorda and Anegada) although these have little practical relevance. Law and criminal justice Crime in the British Virgin Islands is comparatively low by Caribbean standards. Whilst statistics and hard data are relatively rare, and are not regularly published by governmental sources in the British Virgin Islands, the Premier did announce that in 2013 there has been a 14% decline in recorded crime as against 2012. Homicides are rare, with just one incident recorded in 2013. The Virgin Islands Prison Service operates a single facility, His Majesty's Prison in East End, Tortola. The British and US Virgin Islands sit at the axis of a major drugs transshipment point between Latin America and the continental United States. The American Drug Enforcement Administration regards the adjacent US territories of Puerto Rico and the US Virgin Islands as a "High Intensity Drug Trafficking Area". A co-operation agreement exists between the British Virgin Islands and the US Coast Guard allowing American forces to pursue suspected drug traffickers through the territorial waters of the British Virgin Islands. In August 2011 a joint raid between the American DEA and the Royal Virgin Islands Police Force arrested a number of British Virgin Islands residents who are accused of being involved in major drugs transshipments, although their extradition to the United States has since become stalled in protracted legal wrangling. Military As a British Overseas territory, defence of the islands is the responsibility of the United Kingdom. Economy The twin pillars of the economy are financial services (60%) and tourism (roughly 40-45% of GDP). Politically, tourism is the more important of the two, as it employs a greater number of people within the territory, and a larger proportion of the businesses in the tourist industry are locally owned, as are a number of the highly tourism-dependent sole traders (for example, taxi drivers and street vendors). Economically however, financial services associated with the territory's status as an offshore financial centre are by far the more important. 51.8% of the Government's revenue comes directly from licence fees for offshore companies, and considerable further sums are raised directly or indirectly from payroll taxes relating to salaries paid within the trust industry sector (which tend to be higher on average than those paid in the tourism sector). The official currency of the British Virgin Islands has been the United States dollar (US$) since 1959, the currency also used by the United States Virgin Islands. The British Virgin Islands enjoys one of the more prosperous economies of the Caribbean region, with a per capita average income of around $42,300 (2010 est.) The average monthly income earned by a worker in the territory was US$2,452 as at the time of the 2010 Census. 29% of the population fell into the "low income" category. Although it is common to hear criticism in the British Virgin Islands' press about income inequality, no serious attempt has been made by economists to calculate a Gini coefficient or similar measure of income equality for the territory. A report from 2000 suggested that, despite the popular perception, income inequality was actually lower in the British Virgin Islands than in any other OECS state, although in global terms income equality is higher in the Caribbean than in many other regions. Tourism Tourism accounts for approximately 45% of national income. The islands are a popular destination for US citizens. Tourists frequent the numerous white sand beaches, visit The Baths on Virgin Gorda, snorkel the coral reefs near Anegada, or experience the well-known bars of Jost Van Dyke. The BVI are known as one of the world's greatest sailing destinations, and charter sailboats are a very popular way to visit less accessible islands. Established in 1972, the BVI hosts the BVI Spring Regatta and Sailing Festival. A substantial number of the tourists who visit the BVI are cruise ship passengers, and although they produce far lower revenue per head than charter boat tourists and hotel based tourists, they are nonetheless important to the substantial - and politically important - taxi driving community. Only Virgin Islanders are permitted to work as taxi drivers. Financial services Financial services account for over half of the income of the territory. The majority of this revenue is generated by the licensing of offshore companies and related services. The British Virgin Islands is a significant global player in the offshore financial services industry. Since 2001, financial services in the British Virgin Islands have been regulated by the independent Financial Services Commission. The BVI is relied upon for its sophisticated Commercial Court division of the Eastern Caribbean Supreme Court, as well as the more recent BVI Arbitration Centre. Caribbean KCs and British KCs preside over the majority of important cases and the laws of the Virgin Islands are based on English laws, meaning the jurisdiction provides clarity and consistency should parties require commercial disputes to be resolved. Owing to the international nature of BVI companies' operations and asset holdings, the BVI Commercial Court routinely hears highly sophisticated matters at the cutting edge of cross-border litigation and enforcement, where billions of dollars are at issue. Citco, also known as the Citco Group of Companies and the Curaçao International Trust Co., is a privately owned global hedge fund administrator headquartered in the British Virgin Islands, founded in 1948. It is the world's largest hedge fund administrator, managing over $1 trillion in assets under administration. In May 2022, the banking sector of the British Virgin Islands comprised only seven commercial banks and one restricted bank, 12 authorised custodians, two licensed money services businesses and one licensed financing service provider. The British Virgin Islands is frequently referred to as a "tax haven" by campaigners and NGOs, including Oxfam, which itself has investment funds registered in lesser regulated jurisdictions such as Lichtenstein and Delaware and has been expressly named in anti-tax-haven legislation in other countries on various occasions. Successive governments in the British Virgin Islands have implemented tax exchange agreements and verified beneficial ownership information of companies following the 2013 G8 summit putting their governance and regulatory regimes far ahead of many "onshore" jurisdictions. On 10 September 2013, British Prime Minister David Cameron said "I do not think it is fair any longer to refer to any of the Overseas Territories or Crown Dependencies as tax havens. They have taken action to make sure that they have fair and open tax systems. It is very important that our focus should now shift to those territories and countries that really are tax havens." Yet journalist and author for The Economist, Nicholas Shaxson, writes in his 2016 Treasure Islands, tax havens and the men who stole the world: "...Britain sits, spider-like, at the centre of a vast international web of tax havens, which hoover up trillions of dollars' worth of business and capital from around the globe and funnel it up to the City of London. The British Crown Dependencies and Overseas Territories - ...the British Virgin Islands... are some of the biggest players in the offshore world."(pp. vii-viii) Shaxson points out that despite BVI having fewer than 25000 inhabitants, hosts over 800,000 companies. In the April 2016 Panama Papers leak, while all of the wrongdoing by Mossack Fonseca personnel occurred in Panama and the US, the British Virgin Islands was by far the most commonly-used jurisdiction by clients of Mossack Fonseca. In 2022, the verified nature of beneficial ownership registers of the British Overseas Territories and Crown Dependencies were a crucial tool in giving effect to sanctions against Russia and Belarus, enabling the efficient identification and seizure of yachts, real estate and businesses. Foreign Account Tax Compliance Act On 30 June 2014, The British Virgin Islands was deemed to have an Inter- Governmental Agreement (IGA) with the United States of America with respect to the "Foreign Account Tax Compliance Act" of the United States of America. The Model 1 Agreement (14 Pages) recognizes that: The Government of the United Kingdom of Great Britain and Northern Ireland provided a copy of the Letter of Entrustment which was sent to the Government of the British Virgin Islands, to the Government of the United States of America "via diplomatic note of 28 May 2014". The Letter of Entrustment dated 14 July 2010 was originally provided to the Government of the British Virgin Islands and authorised the Government of the BVI "to negotiate and conclude Agreements relating to taxation that provide for exchange of information on tax matters to the OECD standard" (Paragraph 2 of the FATCA Agreement). Via an "Entrustment Letter" dated 24 March 2014, The Government of the United Kingdom, authorised the Government of the BVI to sign an agreement on information exchange to facilitate the Implementation of the Foreign Account Tax Compliance Act. On 27 March 2017, the US Treasury site disclosed that the Model 1 agreement and related agreement were "In Force" on 13 July 2015. Sanctions and Anti-Money Laundering Act Under the UK Sanctions and Anti-Money Laundering Act of 2018, beneficial ownership of companies in British overseas territories such as the British Virgin Islands must be publicly registered for disclosure by 31 December 2020. The Government of the British Virgin Islands has not yet formally challenged this law, yet has criticised it, noting that it violates the Constitutional sovereignty granted to the islands, and would in practice be relatively ineffective in anti-money laundering and counter-terrorism financing, while raising serious privacy and human rights issues. Further, this would put the British Virgin Islands in a position where it would be at a severe disadvantage because other International Finance Centres do not have this in place, and in the case of the US and the UK, there is very little near-term prospect of the same. In late 2022, both of the USA and EU appeared to have endorsed the British Overseas Territories' beneficial ownership register regimes. In a judgment dated 22 November 2022, the European Court of Justice (ECJ) has at last decided that open public access to the beneficial owner registers of EU member state companies is no longer valid, as it is in contravention of articles 7 and 8 of the Charter of Fundamental Rights of the European Union (the Charter). The USA appears to have come to a similar conclusion regarding balancing confidentiality and legitimate privacy with the Anti-Money Laundering advantages of having verified beneficial ownerships registers. The resultant goal appears to be to bring the USA in line with the current Cayman and BVI regimes. The UK's Crown Dependencies have already stated that they will not implement public registers without beforehand having received fresh legal advice on the matter and it is thought that the Overseas Territories would logically take a similar position. The UK is yet to come out in support of the BOTs and CDs and their current gold standard regulatory positions. Agriculture and industry Agriculture and industry account for only a small proportion of the islands' GDP. Agricultural produce includes fruit, vegetables, sugar cane, livestock and poultry, and industries include rum distillation, construction and boat building. Commercial fishing is also practised in the islands' waters. Workforce The British Virgin Islands is heavily dependent on migrant workers, and over 50% of all workers on the islands are of a foreign descent. Only 37% of the entire population were born in the territory. The national labour-force is estimated at 12,770, of whom approximately 59.4% work in the service sector but less than 0.6% are estimated to work in agriculture (the balance working in industry). The British Virgin Islands has met challenges in recruiting sufficient numbers in recent years, having been affected by hurricanes Irma and Maria, and having continued to lag behind other jurisdictions in providing a reliable permanent residence regime. This has had a knock-on effect in limiting schooling and amenities when compared to IFCs like Cayman, UAE, Singapore, and Hong Kong. CARICOM status and the CARICOM Single Market Economy As of 2 July 1991, the British Virgin Islands holds Associate Member status in CARICOM, the Caribbean Single Market and Economy (CSME). In recognition of the CARICOM (Free Movement) Skilled Persons Act which came into effect in July 1997 in some of the CARICOM countries such as Jamaica and which has been adopted in other CARICOM countries, such as Trinidad and Tobago, it is possible that CARICOM nationals who hold the "A Certificate of Recognition of Caribbean Community Skilled Person" may be allowed to work in the BVI under normal working conditions. Transport There are of roads. The main airport, Terrance B. Lettsome International Airport, also known as Beef Island Airport, is located on Beef Island, which lies off the eastern tip of Tortola and is accessible by the Queen Elizabeth II Bridge. Cape Air, and Air Sunshine are among the airlines offering scheduled service. Virgin Gorda and Anegada have their own smaller airports. Private air charter services operated by Island Birds Air Charter fly directly to all three islands from any major airport in the Caribbean. Helicopters are used to get to islands with no runway facilities; Antilles Helicopter Services is the only helicopter service based in the country. The main harbour is in Road Town. There are also ferries that operate within the British Virgin Islands and to the neighbouring United States Virgin Islands. Cars in the British Virgin Islands drive on the left just as they do in the United Kingdom and the United States Virgin Islands. However, most cars are left hand drive, because they are from the United States. The roads are often quite steep, narrow and winding, and ruts, mudslides and rockfall can be a problem when it rains. Demographics As of the 2010 Census, the population of the territory was 28,054. Estimates put the population at 35,800 (July 2018) yet in 2022, it is thought to be much less than 30,000 post-Irma and with people having left during COVID lockdowns due to unemployment in the tourism industry. The majority of the population (76.9%) are Afro-Caribbean, descended from slaves brought to the islands by the British. Other large ethnic groups include Latinos (5.6%), those of European ancestry (5.4%), Mixed ancestry (5.4%) and Indian (2.1%). The 2010 Census reports: 76.9% African 5.6% Hispanic 5.4% European/Caucasian 5.4% Mixed 2.1% East Indian 4.6% Others* The 2010 Census reports the main places of origin of residents as follows: 39.1% local born (though many locals go to St. Thomas or the United States for maternity services) 7.2% Guyana 7.0% St. Vincent and the Grenadines 6.0% Jamaica 5.5% United States 5.4% Dominican Republic 5.3% United States Virgin Islands The islands are heavily dependent upon migrant labour. In 2004, migrant workers accounted for 50% of the total population. 32% of workers employed in the British Virgin Islands work for the government. In the late 2000s the first Overseas Filipino Worker came to the British Virgin Islands, by 2020 total British Filipino population was about 800. Unusually, the territory has one of the highest drowning mortality rates in the world, being higher than other high-risk countries such as China and India. 20% of deaths in the British Virgin Islands during 2012 were recorded as drownings, all of them being tourists. Despite this, the territory's most popular beach still has no lifeguard presence. Religion Over 90% of the population who indicated a religious affiliation at the 2010 Census were Christian with the largest individual Christian denominations being Methodist (17.6%), Anglican (9.5%), Church of God (10.4%), Seventh-Day Adventists (9.0%) and Roman Catholic (8.9%). The largest non-Christian faiths in 2010 were Hinduism (1.9%) and Islam (0.9%). However Hindus and Muslims constitute each approximately 1.2% of the population according to Word Religion Database 2005. The Constitution of the British Virgin Islands commences with a professed national belief in God. Education The British Virgin Islands operates several government schools as well as private schools. There is also a community college, H. Lavity Stoutt Community College, that is located on the eastern end of Tortola. This college was named after Lavity Stoutt, the first Chief Minister of the British Virgin Islands. There remains segregation in the school system; while BVIslander and Belonger children make up a significant proportion of pupils in private schools, Non-Belongers are prohibited from attending government schools. It is extremely common for students from the British Virgin Islands to travel overseas for secondary and tertiary education, either to the University of the West Indies, or to colleges and universities in either the United Kingdom, United States or Canada. Coaching in certain sports, such as athletics, squash and football is of a high level. The literacy rate in the British Virgin Islands is high at 98%. There is a University of the West Indies Open campus in the territory and a Marine Science educational facility. Culture Language The primary language is English, although there is a local dialect. Spanish is spoken by Puerto Rican, Dominican and other Hispanic immigrants. Music The traditional music of the British Virgin Islands is called fungi after the local cornmeal dish with the same name, often made with okra. The special sound of fungi is due to a unique local fusion between African and European music. It functions as a medium of local history and folklore and is therefore a cherished cultural form of expression that is part of the curriculum in BVI schools. The fungi bands, also called "scratch bands", use instruments ranging from calabash, washboard, bongos and ukulele, to more traditional western instruments like keyboard, banjo, guitar, bass, triangle and saxophone. Apart from being a form of festive dance music, fungi often contains humorous social commentaries, as well as BVI oral history. Sport Because of its location and climate, the British Virgin Islands has long been a haven for sailing enthusiasts. Sailing is regarded as one of the foremost sports in all of the BVI. Calm waters and steady breezes provide some of the best sailing conditions in the Caribbean. Many sailing events are held in the waters of this country, the largest of which is a week-long series of races called the Spring Regatta, the premier sailing event of the Caribbean, with several races hosted each day. Boats include everything from full-size mono-hull yachts to dinghies. Captains and their crews come from all around the world to attend these races. The Spring Regatta is part race, part party, part festival. The Spring Regatta is normally held during the first week of April. Since 2009, the BVI have made a name for themselves as a host of international basketball events. The BVI hosted three of the last four events of the Caribbean Basketball Championship (FIBA CBC Championship).

Burkina Faso

Burkina Faso ( , ; , ) is a landlocked country in West Africa with an area of , bordered by Mali to the northwest, Niger to the northeast, Benin to the southeast, Togo and Ghana to the south, and the Ivory Coast to the southwest. As of 2021, the country had an estimated population of 20,321,378. Previously called Republic of Upper Volta (1958–1984), it was renamed Burkina Faso by President Thomas Sankara. Its citizens are known as Burkinabè ( ), and its capital and largest city is Ouagadougou. Its name is often translated into English as the "Land of Honest Men". The largest ethnic group in Burkina Faso is the Mossi people, who settled the area in the 11th and 13th centuries. They established powerful kingdoms such as the Ouagadougou, Tenkodogo, and Yatenga. In 1896, it was colonized by the French as part of French West Africa; in 1958, Upper Volta became a self-governing colony within the French Community. In 1960, it gained full independence with Maurice Yaméogo as president. Since it gained its independence, the country was subject to instability, droughts, famines and corruption. Various coups have also taken place in the country, in 1966, 1980, 1982, 1983, 1987, and twice in 2022, in January and in September, as well as an attempt in 1989 and another in 2015. Thomas Sankara came to power following a successful coup in 1982. As president, Sankara embarked on a series of ambitious socioeconomic reforms which included a nationwide literacy campaign, land redistribution to peasants, provided vaccinations to over 2 million children, railway and road construction, equalized access to education, and the outlawing of female genital mutilation, forced marriages, and polygamy. He served as the country's president until 1987 when he was deposed and assassinated in a coup led by Blaise Compaoré, who became president and ruled the country until his removal on 31 October 2014. Burkina Faso has been severely affected by the rise of Islamist terrorism in the Sahel since the mid-2010s. Several militias, partly allied with the Islamic State (IS) or al-Qaeda, operate in Burkina Faso and across the border in Mali and Niger. More than one million of the country's 21 million inhabitants are internally displaced persons. Burkina Faso's military seized power in a coup d'état on 23–24 January 2022, overthrowing President Roch Marc Kaboré. On 31 January, the military junta restored the constitution and appointed Paul-Henri Sandaogo Damiba as interim president, who was himself overthrown in a second coup on 30 September and replaced by military captain Ibrahim Traoré. Burkina Faso is one of the least developed countries, with a GDP of $16.226 billion. Approximately 63.8 percent of its population practices Islam, while 26.3 percent practice Christianity. The country's official language of government and business is French. There are 60 indigenous languages officially recognized by the Burkinabè government, with the most common language, Mooré, spoken by over half the population. The country has a strong culture and is geographically biodiverse, with plentiful reserves of gold, manganese, copper and limestone. Burkinabè art has a rich and long history, and is globally renowned for its orthodox style. The country is governed as a semi-presidential republic with executive, legislative and judicial powers. Burkina Faso is a member of the United Nations, La Francophonie and the Organisation of Islamic Cooperation. It is currently suspended from ECOWAS and the African Union. Etymology Formerly the Republic of Upper Volta, the country was renamed "Burkina Faso" on 4 August 1984 by then-President Thomas Sankara. The words "Burkina" and "Faso" stem from different languages spoken in the country: "Burkina" comes from Mooré and means "upright", showing how the people are proud of their integrity, while "Faso" comes from the Dioula language (as written in N'Ko: faso) and means "fatherland" (literally, "father's house"). The "-bè" suffix added onto "Burkina" to form the demonym "Burkinabè" comes from the Fula language and means "women or men". The CIA summarizes the etymology as "land of the honest (incorruptible) men". The French colony of Upper Volta was named for its location on the upper courses of the Volta River (the Black, Red and White Volta). History Early history The northwestern part of present-day Burkina Faso was populated by hunter-gatherers from 14,000 BCE to 5000 BCE. Their tools, including scrapers, chisels and arrowheads, were discovered in 1973 through archaeological excavations. Agricultural settlements were established between 3600 and 2600 BCE. The Bura culture was an Iron-Age civilization centred in the southwest portion of modern-day Niger and in the southeast part of contemporary Burkina Faso. Iron industry, in smelting and forging for tools and weapons, had developed in Sub-Saharan Africa by 1200 BCE. To date, the oldest evidence of iron smelting found in Burkina Faso dates from 800 to 700 BC and form part of the Ancient Ferrous Metallurgy World Heritage Site. From the 3rd to the 13th centuries CE, the Iron Age Bura culture existed in the territory of present-day southeastern Burkina Faso and southwestern Niger. Various ethnic groups of present-day Burkina Faso, such as the Mossi, Fula and Dioula, arrived in successive waves between the 8th and 15th centuries. From the 11th century, the Mossi people established several separate kingdoms. 8th century to 18th century There is debate about the exact dates when Burkina Faso's many ethnic groups arrived to the area. The Proto-Mossi arrived in the far Eastern part of what is today Burkina Faso sometime between the 8th and 11th centuries, the Samo arrived around the 15th century, the Dogon lived in Burkina Faso's north and northwest regions until sometime in the 15th or 16th centuries and many of the other ethnic groups that make up the country's population arrived in the region during this time. During the Middle Ages, the Mossi established several separate kingdoms including those of Tenkodogo, Yatenga, Zandoma, and Ouagadougou. Sometime between 1328 and 1338 Mossi warriors raided Timbuktu but the Mossi were defeated by Sonni Ali of Songhai at the Battle of Kobi in Mali in 1483. During the early 16th century the Songhai conducted many slave raids into what is today Burkina Faso. During the 18th century the Gwiriko Empire was established at Bobo Dioulasso and ethnic groups such as the Dyan, Lobi, and Birifor settled along the Black Volta. From colony to independence (1890s–1958) Starting in the early 1890s during the European Scramble for Africa, a series of European military officers made attempts to claim parts of what is today Burkina Faso. At times these colonialists and their armies fought the local peoples; at times they forged alliances with them and made treaties. The colonialist officers and their home governments also made treaties among themselves. The territory of Burkina Faso was invaded by France, becoming a French protectorate in 1896. The eastern and western regions, where a standoff against the forces of the powerful ruler Samori Ture complicated the situation, came under French occupation in 1897. By 1898, the majority of the territory corresponding to Burkina Faso was nominally conquered; however, French control of many parts remained uncertain. The Franco-British Convention of 14 June 1898 created the country's modern borders. In the French territory, a war of conquest against local communities and political powers continued for about five years. In 1904, the largely pacified territories of the Volta basin were integrated into the Upper Senegal and Niger colony of French West Africa as part of the reorganization of the French West African colonial empire. The colony had its capital in Bamako. The language of colonial administration and schooling became French. The public education system started from humble origins. Advanced education was provided for many years during the colonial period in Dakar. The indigenous population was highly discriminated against. For example, African children were not allowed to ride bicycles or pick fruit from trees, "privileges" reserved for the children of colonists. Violating these regulations could land parents in jail. Draftees from the territory participated in the European fronts of World War I in the battalions of the Senegalese Rifles. Between 1915 and 1916, the districts in the western part of what is now Burkina Faso and the bordering eastern fringe of Mali became the stage of one of the most important armed oppositions to colonial government: the Volta-Bani War. The French government finally suppressed the movement but only after suffering defeats. It also had to organize its largest expeditionary force of its colonial history to send into the country to suppress the insurrection. Armed opposition wracked the Sahelian north when the Tuareg and allied groups of the Dori region ended their truce with the government. French Upper Volta was established on 1 March 1919. The French feared a recurrence of armed uprising and had related economic considerations. To bolster its administration, the colonial government separated the present territory of Burkina Faso from Upper Senegal and Niger. The new colony was named Haute Volta for its location on the upper courses of the Volta River (the Black, Red and White Volta), and François Charles Alexis Édouard Hesling became its first governor. Hesling initiated an ambitious road-making program to improve infrastructure and promoted the growth of cotton for export. The cotton policy – based on coercion – failed, and revenue generated by the colony stagnated. The colony was dismantled on 5 September 1932, being split between the French colonies of Ivory Coast, French Sudan and Niger. Ivory Coast received the largest share, which contained most of the population as well as the cities of Ouagadougou and Bobo-Dioulasso. France reversed this change during the period of intense anti-colonial agitation that followed the end of World War II. On 4 September 1947, it revived the colony of Upper Volta, with its previous boundaries, as a part of the French Union. The French designated its colonies as departments of metropolitan France on the European continent. On 11 December 1958 the colony achieved self-government as the Republic of Upper Volta; it joined the Franco-African Community. A revision in the organization of French Overseas Territories had begun with the passage of the Basic Law (Loi Cadre) of 23 July 1956. This act was followed by reorganization measures approved by the French parliament early in 1957 to ensure a large degree of self-government for individual territories. Upper Volta became an autonomous republic in the French community on 11 December 1958. Full independence from France was received in 1960. Upper Volta (1958–1984) The Republic of Upper Volta () was established on 11 December 1958 as a self-governing colony within the French Community. The name Upper Volta related to the nation's location along the upper reaches of the Volta River. The river's three tributaries are called the Black, White and Red Volta. These were expressed in the three colors of the former national flag. Before attaining autonomy, it had been French Upper Volta and part of the French Union. On 5 August 1960, it attained full independence from France. The first president, Maurice Yaméogo, was the leader of the Voltaic Democratic Union (UDV). The 1960 constitution provided for election by universal suffrage of a president and a national assembly for five-year terms. Soon after coming to power, Yaméogo banned all political parties other than the UDV. The government lasted until 1966. After much unrest, including mass demonstrations and strikes by students, labor unions, and civil servants, the military intervened. Lamizana's rule and multiple coups The 1966 military coup deposed Yaméogo, suspended the constitution, dissolved the National Assembly, and placed Lt. Col. Sangoulé Lamizana at the head of a government of senior army officers. The army remained in power for four years. On 14 June 1976, the Voltans ratified a new constitution that established a four-year transition period toward complete civilian rule. Lamizana remained in power throughout the 1970s as president of military or mixed civil-military governments. Lamizana's rule coincided with the beginning of the Sahel drought and famine which had a devastating impact on Upper Volta and neighboring countries. After conflict over the 1976 constitution, a new constitution was written and approved in 1977. Lamizana was re-elected by open elections in 1978. Lamizana's government faced problems with the country's traditionally powerful trade unions, and on 25 November 1980, Col. Saye Zerbo overthrew President Lamizana in a bloodless coup. Colonel Zerbo established the Military Committee of Recovery for National Progress as the supreme governmental authority, thus eradicating the 1977 constitution. Colonel Zerbo also encountered resistance from trade unions and was overthrown two years later by Maj. Dr. Jean-Baptiste Ouédraogo and the Council of Popular Salvation (CSP) in the 1982 Upper Voltan coup d'état. The CSP continued to ban political parties and organizations, yet promised a transition to civilian rule and a new constitution. 1983 coup d'état Infighting developed between the right and left factions of the CSP. The leader of the leftists, Capt. Thomas Sankara, was appointed prime minister in January 1983, but was subsequently arrested. Efforts to free him, directed by Capt. Blaise Compaoré, resulted in a military coup d'état on 4 August 1983. The coup brought Sankara to power and his government began to implement a series of revolutionary programs which included mass-vaccinations, infrastructure improvements, the expansion of women's rights, encouragement of domestic agricultural consumption, and anti-desertification projects. Burkina Faso (since 1984) On 2 August 1984, on President Sankara's initiative, the country's name changed from "Upper Volta" to "Burkina Faso", or land of the honest men; (the literal translation is land of the upright men.) The presidential decree was confirmed by the National Assembly on 4 August. The demonym for people of Burkina Faso, "Burkinabè", includes expatriates or descendants of people of Burkinabè origin. Sankara's government comprised the National Council for the Revolution (CNR – ), with Sankara as its president, and established popular Committees for the Defense of the Revolution (CDRs). The Pioneers of the Revolution youth programme was also established. Sankara launched an ambitious socioeconomic programme for change, one of the largest ever undertaken on the African continent. His foreign policies centred on anti-imperialism, with his government rejecting all foreign aid, pushing for odious debt reduction, nationalising all land and mineral wealth and averting the power and influence of the International Monetary Fund (IMF) and World Bank. His domestic policies included a nationwide literacy campaign, land redistribution to peasants, railway and road construction and the outlawing of female genital mutilation, forced marriages and polygamy. Sankara pushed for agrarian self-sufficiency and promoted public health by vaccinating 2,500,000 children against meningitis, yellow fever, and measles. His national agenda also included planting over 10,000,000 trees to halt the growing desertification of the Sahel. Sankara called on every village to build a medical dispensary and had over 350 communities build schools with their own labour. In the 1980s, when ecological awareness was still very low, Thomas Sankara was one of the few African leaders to consider environmental protection a priority. He engaged in three major battles: against bush fires "which will be considered as crimes and will be punished as such"; against cattle roaming "which infringes on the rights of peoples because unattended animals destroy nature"; and against the anarchic cutting of firewood "whose profession will have to be organized and regulated". As part of a development program involving a large part of the population, ten million trees were planted in Burkina Faso in fifteen months during the revolution. To face the advancing desert and recurrent droughts, Thomas Sankara also proposed the planting of wooded strips of about fifty kilometers, crossing the country from east to west. He then thought of extending this vegetation belt to other countries. Cereal production, close to 1.1 billion tons before 1983, was predicted to rise to 1.6 billion tons in 1987. Jean Ziegler, former UN special rapporteur for the right to food, said that the country "had become food self-sufficient." Compaoré presidency On 15 October 1987, Sankara, along with twelve other officials, was assassinated in a coup d'état organized by Blaise Compaoré, Sankara's former colleague, who would go on to serve as Burkina Faso's president from October 1987 until October 2014. After the coup and although Sankara was known to be dead, some CDRs mounted an armed resistance to the army for several days. A majority of Burkinabè citizens hold that France's foreign ministry, the Quai d'Orsay, was behind Compaoré in organizing the coup. There is some evidence for France's support of the coup. Compaoré gave as one of the reasons for the coup the deterioration in relations with neighbouring countries. Compaoré argued that Sankara had jeopardised foreign relations with the former colonial power (France) and with neighbouring Ivory Coast. Following the coup Compaoré immediately reversed the nationalizations, overturned nearly all of Sankara's policies, returned the country back into the IMF fold, and ultimately spurned most of Sankara's legacy. Following an alleged coup-attempt in 1989, Compaoré introduced limited democratic reforms in 1990. Under the new (1991) constitution, Compaoré was re-elected without opposition in December 1991. In 1998 Compaoré won election in a landslide. In 2004, 13 people were tried for plotting a coup against President Compaoré and the coup's alleged mastermind was sentenced to life imprisonment. , Burkina Faso remained one of the least-developed countries in the world. In 2000, the constitution was amended to reduce the presidential term to five years and set term limits to two, preventing successive re-election. The amendment took effect during the 2005 elections. If passed beforehand, it would have prevented Compaoré from being reelected. Other presidential candidates challenged the election results. But in October 2005, the constitutional council ruled that, because Compaoré was the sitting president in 2000, the amendment would not apply to him until the end of his second term in office. This cleared the way for his candidacy in the 2005 election. On 13 November 2005, Compaoré was reelected in a landslide, because of a divided political opposition. In the 2010 presidential election, President Compaoré was re-elected. Only 1.6 million Burkinabè voted, out of a total population 10 times that size. In February 2011, the death of a schoolboy provoked the 2011 Burkinabè protests, a series of popular protests, coupled with a military mutiny and a magistrates' strike, that called for the resignation of Compaoré, democratic reforms, higher wages for troops and public servants and economic freedom. As a result, governors were replaced and wages for public servants were raised. In April 2011, there was an army mutiny; the president named new chiefs of staff, and a curfew was imposed in Ouagadougou. Compaoré's government played the role of negotiator in several West-African disputes, including the 2010–11 Ivorian crisis, the Inter-Togolese Dialogue (2007), and the 2012 Malian Crisis. Kafando presidency Starting on 28 October 2014 protesters began to march and demonstrate in Ouagadougou against President Compaoré, who appeared ready to amend the constitution and extend his 27-year rule. On 30 October some protesters set fire to the parliament building and took over the national TV headquarters. Ouagadougou International Airport closed and MPs suspended the vote on changing the constitution (the change would have allowed Compaoré to stand for re-election in 2015). Later in the day, the military dissolved all government institutions and imposed a curfew. On 31 October 2014, President Compaoré, facing mounting pressure, resigned after 27 years in office. Lt. Col. Isaac Zida said that he would lead the country during its transitional period before the planned 2015 presidential election, but there were concerns over his close ties to the former president. In November 2014 opposition parties, civil-society groups and religious leaders adopted a plan for a transitional authority to guide Burkina Faso to elections. Under the plan Michel Kafando became the transitional President of Burkina Faso and Lt. Col. Zida became the acting Prime Minister and Defense Minister. On 16 September 2015, the Regiment of Presidential Security (RSP) carried out a coup d'état, seizing the president and prime minister and then declaring the National Council for Democracy the new national government. However, on 22 September 2015, the coup leader, Gilbert Diendéré, apologized and promised to restore civilian government. On 23 September 2015 the prime minister and interim president were restored to power. Kaboré presidency and Jihadist insurgency (2015-2023) General elections took place on 29 November 2015. Roch Marc Christian Kaboré won the election in the first round with 53.5% of the vote, defeating businessman Zéphirin Diabré, who took 29.7%. Kaboré was sworn in as president on 29 December 2015. Kaboré was re-elected in the general election of 22 November 2020, but his party Mouvement du Peuple pour le Progrès (MPP), failed to reach absolute parliamentary majority. It secured 56 seats out of a total of 127. The Congress for Democracy and Progress (CDP), the party of former President Blaise Compaoré, was distant second with 20 seats. A Jihadist insurgency began in August 2015, part of the Islamist insurgency in the Sahel. Between August 2015 and October 2016, seven different posts were attacked across the country. On 15 January 2016, terrorists attacked the capital city of Ouagadougou, killing 30 people. Al-Qaeda in the Islamic Maghreb and Al-Mourabitoune, which until then had mostly operated in neighbouring Mali, claimed responsibility for the attack. In 2016, attacks increased after a new group Ansarul Islam, led by imam Ibrahim Malam Dicko, was founded. Its attacks focussed particularly on Soum province and it killed dozens of people in the attack on Nassoumbou on 16 December. Between 27 March – 10 April 2017, the governments of Mali, France, and Burkina Faso launched a joint operation named "Operation Panga," composed of 1,300 soldiers from the three countries, in Fhero forest, near the Burkina Faso-Mali border, considered a sanctuary for Ansarul Islam. The head of Ansarul Islam, Ibrahim Malam Dicko, was killed in June 2017 and Jafar Dicko became leader. On 2 March 2018, Jama'at Nasr al-Islam wal Muslimin attacked the French embassy in Ouagadougou as well as the general staff of the Burkinabè army. Eight soldiers and eight attackers were killed, and a further 61 soldiers and 24 civilians were injured. The insurgency expanded to the east of the country and, in early October, the Armed Forces of Burkina Faso launched a major military operation in the country's East, supported by French forces. According to Human Rights Watch, between mid-2018 to February 2019, at least 42 people were murdered by jihadists and a minimum of 116 mostly Fulani civilians were killed by military forces without trial. The attacks increased significantly in 2019. According to the ACLED, armed violence in Burkina Faso jumped by 174% in 2019, with nearly 1,300 civilians dead and 860,000 displaced. Jihadist groups also began to specifically target Christians. On 8 July 2020, the United States raised concerns after a Human Rights Watch report revealed mass graves with at least 180 bodies, which were found in northern Burkina Faso where soldiers were fighting jihadists. On 4 June 2021, the Associated Press reported that according to the government of Burkina Faso, gunmen killed at least 100 people in Solhan village in northern Burkina Faso near the Niger border. A local market and several homes were also burned down. A government spokesman blamed jihadists. Heni Nsaibia, senior researcher at the Armed Conflict Location & Event Data Project said it was the deadliest attack recorded in Burkina Faso since the beginning of the jihadist insurgency. From 4–5 June 2021, unknown militants massacred over 170 people in the villages of Solhan and Tadaryat. Jihadists killed 80 people in Gorgadji on 20 August. On 14 November, the Jama'at Nasr al-Islam wal Muslimin attacked a gendarmerie in Inata, killing 53 soldiers, the heaviest loss of life by the Burkinabe military during the insurgency, and a major morale loss in the country. In December Islamists killed 41 people in an ambush, including the popular vigilante leader Ladji Yoro. Yoro was a central figure in the Volunteers for the Defense of the Homeland (VDP) a pro-government militia that had taken a leading role in the struggle against Islamists. In 2023, shortly after the murder of a Catholic priest at the hands of insurgents, the bishop of Dori, Laurent Dabiré, claimed in an interview with Catholic charity Aid to the Church in Need that around 50% of the country was in the hands of Islamists. 2022 coups d'état In a successful coup on 24 January 2022, mutinying soldiers arrested and deposed President Roch Marc Christian Kaboré following gunfire. The Patriotic Movement for Safeguard and Restoration (MPSR) supported by the military declared itself to be in power, led by Lieutenant Colonel Paul-Henri Sandaogo Damiba. On 31 January, the military junta restored the constitution and appointed Damiba interim president. In the aftermath of the coup, ECOWAS and the African Union suspended Burkina Faso's membership. On 10 February, the Constitutional Council declared Damiba president of Burkina Faso. He was sworn in as president on 16 February. On 1 March 2022, the junta approved a charter allowing a military-led transition of 3 years. The charter provides for the transition process to be followed by the holding of elections. President Kaboré, who had been detained since the military junta took power, was released on 6 April 2022. The insurgency continued following the coup, with about 60% of the country under government control. The Siege of Djibo began in February 2022 and continues as of June 2023. Between 100 and 165 people were killed in Seytenga Department, Séno Province on 12–13 June and around 16,000 people fled their homes. In June, the Government announced the creation of "military zones", which civilians were required to vacate so that the country's Armed and Security Forces could fight insurgents without any "hindrances". On 30 September, Damiba was ousted in a military coup led by Capt. Ibrahim Traoré. This came eight months after Damiba seized power. The rationale given by Traore for the coup d'état was the purported inability of Paul-Henri Sandaogo Damiba to deal with an Islamist insurgency. Damiba resigned and left the country. On 6 October 2022, Captain Ibrahim Traore was officially appointed as president of Burkina Faso. Apollinaire Joachim Kyélem de Tambèla was appointed interim Prime Minister on 21 October 2022. On 13 April 2023, authorities in Burkina Faso declared a mobilisation in order to give the nation all means necessary to combat terrorism and create a "legal framework for all the actions to be taken" against the insurgents in recapturing 40 percent of the national territory from Islamist insurgents. On 20 April, the Rapid Intervention Brigade committed the Karma massacre, rounding up and executing civilians en masse. Between 60 and 156 civilians were killed. Government The constitution of 2 June 1991 established a semi-presidential government: its parliament could be dissolved by the President of the Republic, who was to be elected for a term of seven years. In 2000, the constitution was amended to reduce the presidential term to five years and set term limits to two, preventing successive re-election. The amendment took effect during the 2005 elections. The parliament consisted of one chamber known as the National Assembly, which had 111 seats with members elected to serve five-year terms. There was also a constitutional chamber, composed of ten members, and an economic and social council whose roles were purely consultative. The 1991 constitution created a bicameral parliament, but the upper house (Chamber of Representatives) was abolished in 2002. The Compaoré administration had worked to decentralize power by devolving some of its powers to regions and municipal authorities. But the widespread distrust of politicians and lack of political involvement by many residents complicated this process. Critics described this as a hybrid decentralisation. Political freedoms are severely restricted in Burkina Faso. Human rights organizations had criticised the Compaoré administration for numerous acts of state-sponsored violence against journalists and other politically active members of society. The prime minister is head of government and is appointed by the president with the approval of the National Assembly. He is responsible for recommending a cabinet for appointment by the president. Constitution In 2015, Kaboré promised to revise the 1991 constitution. The revision was completed in 2018. One condition prevents any individual from serving as president for more than ten years either consecutively or intermittently and provides a method for impeaching a president. A referendum on the constitution for the Fifth Republic was scheduled for 24 March 2019. Certain rights are also enshrined in the revised wording: access to drinking water, access to decent housing and a recognition of the right to civil disobedience, for example. The referendum was required because the opposition parties in Parliament refused to sanction the proposed text. Following the January 2022 coup d'état, the military dissolved the parliament, government and constitution. On 31 January, the military junta restored the constitution, but it was suspended again following the September 2022 coup d'état. Foreign relations Burkina Faso is a member of the G5 Sahel, Community of Sahel–Saharan States, La Francophonie, Organisation of Islamic Cooperation, and United Nations. It is currently suspended from ECOWAS and the African Union. Military The army consists of some 6,000 men in voluntary service, augmented by a part-time national People's Militia composed of civilians between 25 and 35 years of age who are trained in both military and civil duties. According to Jane's Sentinel Country Risk Assessment, Burkina Faso's Army is undermanned for its force structure and poorly equipped, but has wheeled light-armour vehicles, and may have developed useful combat expertise through interventions in Liberia and elsewhere in Africa. In terms of training and equipment, the regular Army is believed to be neglected in relation to the élite Regiment of Presidential Security ( – RSP). Reports have emerged in recent years of disputes over pay and conditions. There is an air force with some 19 operational aircraft, but no navy, as the country is landlocked. Military expenses constitute approximately 1.2% of the nation's GDP. Law enforcement Burkina Faso employs numerous police and security forces, generally modeled after organizations used by French police. France continues to provide significant support and training to police forces. The Gendarmerie Nationale is organized along military lines, with most police services delivered at the brigade level. The Gendarmerie operates under the authority of the Minister of Defence, and its members are employed chiefly in the rural areas and along borders. There is a municipal police force controlled by the Ministry of Territorial Administration; a national police force controlled by the Ministry of Security; and an autonomous Regiment of Presidential Security (Régiment de la Sécurité Présidentielle, or RSP), a 'palace guard' devoted to the protection of the President of the Republic. Both the gendarmerie and the national police are subdivided into both administrative and judicial police functions; the former are detailed to protect public order and provide security, the latter are charged with criminal investigations. All foreigners and citizens are required to carry photo ID passports, or other forms of identification or risk a fine, and police spot identity checks are commonplace for persons traveling by auto, bush-taxi, or bus. Administrative divisions The country is divided into 13 administrative regions. These regions encompass 45 provinces and 301 departments. Each region is administered by a governor. Geography Burkina Faso lies mostly between latitudes 9° and 15° N (a small area is north of 15°), and longitudes 6° W and 3° E. It is made up of two major types of countryside. The larger part of the country is covered by a peneplain, which forms a gently undulating landscape with, in some areas, a few isolated hills, the last vestiges of a Precambrian massif. The southwest of the country, on the other hand, forms a sandstone massif, where the highest peak, Ténakourou, is found at an elevation of . The massif is bordered by sheer cliffs up to high. The average altitude of Burkina Faso is and the difference between the highest and lowest terrain is no greater than . Burkina Faso is therefore a relatively flat country. The country owes its former name of Upper Volta to three rivers which cross it: the Black Volta (or Mouhoun), the White Volta (Nakambé) and the Red Volta (Nazinon). The Black Volta is one of the country's only two rivers which flow year-round, the other being the Komoé, which flows to the southwest. The basin of the Niger River also drains 27% of the country's surface. The Niger's tributaries – the Béli, Gorouol, Goudébo, and Dargol – are seasonal streams and flow for only four to six months a year. They still can flood and overflow, however. The country also contains numerous lakes – the principal ones are Tingrela, Bam, and Dem. The country contains large ponds, as well, such as Oursi, Béli, Yomboli, and Markoye. Water shortages are often a problem, especially in the north of the country. Burkina Faso lies within two terrestrial ecoregions: Sahelian Acacia savanna and West Sudanian savanna. Climate Burkina Faso has a primarily tropical climate with two very distinct seasons. In the rainy season, the country receives between of rainfall; in the dry season, the harmattan – a hot dry wind from the Sahara – blows. The rainy season lasts approximately four months, May/June to September, and is shorter in the north of the country. Three climatic zones can be defined: the Sahel, the Sudan-Sahel, and the Sudan-Guinea. The Sahel in the north typically receives less than of rainfall per year and has high temperatures, . A relatively dry tropical savanna, the Sahel extends beyond the borders of Burkina Faso, from the Horn of Africa to the Atlantic Ocean, and borders the Sahara to its north and the fertile region of the Sudan to the south. Situated between 11° 3′ and 13° 5′ north latitude, the Sudan-Sahel region is a transitional zone with regards to rainfall and temperature. Further to the south, the Sudan-Guinea zone receives more than of rain each year and has cooler average temperatures. Geographic and environmental causes can also play a significant role in contributing to Burkina Faso's food insecurity. As the country is situated in the Sahel region, Burkina Faso experiences some of the most radical climatic variation in the world, ranging from severe flooding to extreme drought. The unpredictable climatic shock that Burkina Faso citizens often face results in strong difficulties in being able to rely on and accumulate wealth through agricultural means. Burkina Faso's climate also renders its crops vulnerable to insect attacks, including attacks from locusts and crickets, which destroy crops and further inhibit food production. Not only is most of the population of Burkina Faso dependent on agriculture as a source of income, but they also rely on the agricultural sector for food that will directly feed the household. Due to the vulnerability of agriculture, more and more families are having to look for other sources of non-farm income, and often have to travel outside of their regional zone to find work. Natural resources Burkina Faso's natural resources include gold, manganese, limestone, marble, phosphates, pumice, and salt. Wildlife Burkina Faso has a larger number of elephants than many countries in West Africa. Lions, leopards and buffalo can also be found here, including the dwarf or red buffalo, a smaller reddish-brown animal which looks like a fierce kind of short-legged cow. Other large predators live in Burkina Faso, such as the cheetah, the caracal or African lynx, the spotted hyena and the African wild dog, one of the continent's most endangered species. Burkina Faso's fauna and flora are protected in four national parks: The W National Park in the east which passes Burkina Faso, Benin, and Niger The Arly Wildlife Reserve (Arly National Park in the east) The Léraba-Comoé Classified Forest and Partial Reserve of Wildlife in the west The Mare aux Hippopotames in the west and several reserves: see List of national parks in Africa and Nature reserves of Burkina Faso. Economy The value of Burkina Faso's exports fell from $2.77 billion in 2011 to $754 million in 2012. Agriculture represents 32% of its gross domestic product and occupies 80% of the working population. It consists mostly of rearing livestock. Especially in the south and southwest, the people grow crops of sorghum, pearl millet, maize (corn), peanuts, rice and cotton, with surpluses to be sold. A large part of the economic activity of the country is funded by international aid, despite having gold ores in abundance. The top five export commodities in 2017 were, in order of importance: gems and precious metals, US$1.9 billion (78.5% of total exports), cotton, $198.7 million (8.3%), ores, slag, ash, $137.6 million (5.8%), fruits, nuts: $76.6 million (3.2%) and oil seeds: $59.5 million (2.5%). A December 2018 report from the World Bank indicates that in 2017, economic growth increased to 6.4% in 2017 (vs. 5.9% in 2016) primarily due to gold production and increased investment in infrastructure. The increase in consumption linked to growth of the wage bill also supported economic growth. Inflation remained low, 0.4% that year but the public deficit grew to 7.7% of GDP (vs. 3.5% in 2016). The government was continuing to get financial aid and loans to finance the debt. To finance the public deficit, the Government combined concessional aid and borrowing on the regional market. The World Bank said that the economic outlook remained favorable in the short and medium term, although that could be negatively impacted. Risks included high oil prices (imports), lower prices of gold and cotton (exports) as well as terrorist threat and labour strikes. Burkina Faso is part of the West African Monetary and Economic Union (UMEOA) and has adopted the CFA franc. This is issued by the Central Bank of the West African States (BCEAO), situated in Dakar, Senegal. The BCEAO manages the monetary and reserve policy of the member states, and provides regulation and oversight of financial sector and banking activity. A legal framework regarding licensing, bank activities, organizational and capital requirements, inspections and sanctions (all applicable to all countries of the Union) is in place, having been reformed significantly in 1999. Microfinance institutions are governed by a separate law, which regulates microfinance activities in all WAEMU countries. The insurance sector is regulated through the Inter-African Conference on Insurance Markets (CIMA). In 2018, tourism was almost non-existent in large parts of the country. The U.S. government (and others) warn their citizens not to travel into large parts of Burkina Faso: "The northern Sahel border region shared with Mali and Niger due to crime and terrorism. The provinces of Kmoandjari, Tapoa, Kompienga, and Gourma in East Region due to crime and terrorism". The 2018 CIA World Factbook provides this updated summary. "Burkina Faso is a poor, landlocked country that depends on adequate rainfall. Irregular patterns of rainfall, poor soil, and the lack of adequate communications and other infrastructure contribute to the economy's vulnerability to external shocks. About 80% of the population is engaged in subsistence farming and cotton is the main cash crop. The country has few natural resources and a weak industrial base. Cotton and gold are Burkina Faso's key exports ...The country has seen an upswing in gold exploration, production, and exports. While the end of the political crisis has allowed Burkina Faso's economy to resume positive growth, the country's fragile security situation could put these gains at risk. Political insecurity in neighboring Mali, unreliable energy supplies, and poor transportation links pose long-term challenges." The report also highlights the 2018–2020 International Monetary Fund program, including the government's plan to "reduce the budget deficit and preserve critical spending on social services and priority public investments". A 2018 report by the African Development Bank Group discussed a macroeconomic evolution: "higher investment and continued spending on social services and security that will add to the budget deficit". This group's prediction for 2018 indicated that the budget deficit would be reduced to 4.8% of GDP in 2018 and to 2.9% in 2019. Public debt associated with the National Economic and Social Development Plan was estimated at 36.9% of GDP in 2017. Burkina Faso is a member of the Organization for the Harmonization of Business Law in Africa (OHADA). The country also belongs to the United Nations, International Monetary Fund, World Bank, and World Trade Organization. Mining There is mining of copper, iron, manganese, gold, cassiterite (tin ore), and phosphates. These operations provide employment and generate international aid. Gold production increased 32% in 2011 at six gold mine sites, making Burkina Faso the fourth-largest gold producer in Africa, after South Africa, Mali and Ghana. A 2018 report indicated that the country expected record 55 tonnes of gold in that year, a two-thirds increase over 2013. According to Oumarou Idani, there is a more important issue. "We have to diversify production. We mostly only produce gold, but we have huge potential in manganese, zinc, lead, copper, nickel and limestone". Food insecurity According to the Global Hunger Index, a multidimensional tool used to measure and track a country's hunger levels, Burkina Faso ranked 65 out of 78 countries in 2013. It is estimated that there are currently over 1.5 million children who are at risk of food insecurity in Burkina Faso, with around 350,000 children who are in need of emergency medical assistance. However, only about a third of these children will actually receive adequate medical attention. Only 11.4 percent of children under the age of two receive the daily recommended number of meals. Stunted growth as a result of food insecurity is a severe problem in Burkina Faso, affecting at least a third of the population from 2008 to 2012. Additionally, stunted children, on average, tend to complete less school than children with normal growth development, further contributing to the low levels of education of the Burkina Faso population. The European Commission expects that approximately 500,000 children under age 5 in Burkina Faso will suffer from acute malnutrition in 2015, including around 149,000 who will suffer from its most life-threatening form. Rates of micronutrient deficiencies are also high. According to the Demographic and Health Survey (DHS 2010), 49 percent of women and 88 percent of children under the age of five suffer from anemia. Forty percent of infant deaths can be attributed to malnutrition, and in turn, these infant mortality rates have decreased Burkina Faso's total work force by 13.6 percent, demonstrating how food security affects more aspects of life beyond health. These high rates of food insecurity and the accompanying effects are even more prevalent in rural populations compared to urban ones, as access to health services in rural areas is much more limited and awareness and education of children's nutritional needs is lower. An October 2018 report by USAid stated that droughts and floods remained problematic, and that "violence and insecurity are disrupting markets, trade and livelihoods activities in some of Burkina Faso's northern and eastern areas". The report estimated that over 954,300 people needed food security support, and that, according to UNICEF, an "estimated 187,200 children under 5 years of age will experience severe acute malnutrition". Agencies providing assistance at the time included USAID's Office of Food for Peace (FFP) working with the UN World Food Programme, the NGO Oxfam Intermón and ACDI/VOCA. Approaches to improving food security World Food Programme The United Nations' World Food Programme has worked on programs that are geared towards increasing food security in Burkina Faso. The Protracted Relief and Recovery Operation 200509 (PRRO) was formed to respond to the high levels of malnutrition in Burkina Faso, following the food and nutrition crisis in 2012. The efforts of this project are mostly geared towards the treatment and prevention of malnutrition and include take home rations for the caretakers of those children who are being treated for malnutrition. Additionally, the activities of this operation contribute to families' abilities to withstand future food crises. Better nutrition among the two most vulnerable groups, young children and pregnant women, prepares them to be able to respond better in times when food security is compromised, such as in droughts. The Country Programme (CP) has two parts: food and nutritional assistance to people with HIV/AIDS, and a school feeding program for all primary schools in the Sahel region. The HIV/AIDS nutrition program aims to better the nutritional recovery of those who are living with HIV/AIDS and to protect at-risk children and orphans from malnutrition and food security. As part of the school feeding component, the Country Programme's goals are to increase enrollment and attendance in schools in the Sahel region, where enrollment rates are below the national average. Furthermore, the program aims at improving gender parity rates in these schools, by providing girls with high attendance in the last two years of primary school with take-home rations of cereals as an incentive to households, encouraging them to send their girls to school. The WFP concluded the formation of a subsequently approved plan in August 2018 "to support the Government's vision of 'a democratic, unified and united nation, transforming the structure of its economy and achieving a strong and inclusive growth through patterns of sustainable consumption and production.' It will take important steps in WFP's new strategic direction for strengthened national and local capacities to enable the Government and communities to own, manage, and implement food and nutrition security programmes by 2030". World Bank The World Bank was established in 1944, and comprises five institutions whose shared goals are to end extreme poverty by 2030 and to promote shared prosperity by fostering income growth of the lower forty percent of every country. One of the main projects the World Bank is working on to reduce food insecurity in Burkina Faso is the Agricultural Productivity and Food Security Project. According to the World Bank, the objective of this project is to "improve the capacity of poor producers to increase food production and to ensure improved availability of food products in rural markets." The Agricultural Productivity and Food Security Project has three main parts. Its first component is to work towards the improvement of food production, including financing grants and providing 'voucher for work' programs for households who cannot pay their contribution in cash. The project's next component involves improving the ability of food products, particularly in rural areas. This includes supporting the marketing of food products, and aims to strengthen the capabilities of stakeholders to control the variability of food products and supplies at local and national levels. Lastly, the third component of this project focuses on institutional development and capacity building. Its goal is to reinforce the capacities of service providers and institutions who are specifically involved in project implementation. The project's activities aim to build capacities of service providers, strengthen the capacity of food producer organizations, strengthen agricultural input supply delivery methods, and manage and evaluate project activities. The December 2018 report by the World Bank indicated that the poverty rate fell slightly between 2009 and 2014, from 46% to a still high 40.1%. The report provided this updated summary of the country's development challenges: "Burkina Faso remains vulnerable to climatic shocks related to changes in rainfall patterns and to fluctuations in the prices of its export commodities on world markets. Its economic and social development will, to some extent, be contingent on political stability in the country and the subregion, its openness to international trade, and export diversification". Infrastructure and services Water While services remain underdeveloped, the National Office for Water and Sanitation (ONEA), a state-owned utility company run along commercial lines, is emerging as one of the best-performing utility companies in Africa. High levels of autonomy and a skilled and dedicated management have driven ONEA's ability to improve production of and access to clean water. Since 2000, nearly 2 million more people have access to water in the four principal urban centres in the country; the company has kept the quality of infrastructure high (less than 18% of the water is lost through leaks – one of the lowest in sub-Saharan Africa), improved financial reporting, and increased its annual revenue by an average of 12% (well above inflation). Challenges remain, including difficulties among some customers in paying for services, with the need to rely on international aid to expand its infrastructure. The state-owned, commercially run venture has helped the nation reach its Millennium Development Goal (MDG) targets in water-related areas, and has grown as a viable company. However, access to drinking water has improved over the last 28 years. According to UNICEF, access to drinking water has increased from 39 to 76% in rural areas between 1990 and 2015. In this same time span, access to drinking water increased from 75 to 97% in urban areas. Electricity A 33-megawatt solar power plant in Zagtouli, near Ouagadougou, came online in late November 2017. At the time of its construction, it was the largest solar power facility in West Africa. Other The growth rate in Burkina Faso is high although it continues to be plagued by corruption and incursions from terrorist groups from Mali and Niger. Transport Transport in Burkina Faso is limited by relatively underdeveloped infrastructure. As of June 2014 the main international airport, Ouagadougou Airport, had regularly scheduled flights to many destinations in West Africa as well as Paris, Brussels and Istanbul. The other international airport, Bobo Dioulasso Airport, has flights to Ouagadougou and Abidjan. Rail transport in Burkina Faso consists of a single line which runs from Kaya to Abidjan in Ivory Coast via Ouagadougou, Koudougou, Bobo Dioulasso and Banfora. Sitarail operates a passenger train three times a week along the route. There are 15,000 kilometres of roads in Burkina Faso, of which 2,500 kilometres are paved. Science and technology In 2009, Burkina Faso spent 0.20% of GDP on research and development (R&D), one of the lowest ratios in West Africa. There were 48 researchers (in full-time equivalents) per million inhabitants in 2010, which is more than twice the average for sub-Saharan Africa (20 per million population in 2013) and higher than the ratio for Ghana and Nigeria (39). It is, however, much lower than the ratio for Senegal (361 per million inhabitants). In Burkina Faso in 2010, 46% of researchers were working in the health sector, 16% in engineering, 13% in natural sciences, 9% in agricultural sciences, 7% in the humanities and 4% in social sciences. Burkina Faso was ranked 124th in the Global Innovation Index in 2023. In January 2011, the government created the Ministry of Scientific Research and Innovation. Up until then, management of science, technology and innovation had fallen under the Department of Secondary and Higher Education and Scientific Research. Within this ministry, the Directorate General for Research and Sector Statistics is responsible for planning. A separate body, the Directorate General of Scientific Research, Technology and Innovation, co-ordinates research. This is a departure from the pattern in many other West African countries where a single body fulfils both functions. The move signals the government's intention to make science and technology a development priority. In 2012, Burkina Faso adopted a National Policy for Scientific and Technical Research, the strategic objectives of which are to develop R&D and the application and commercialization of research results. The policy also makes provisions for strengthening the ministry's strategic and operational capacities. One of the key priorities is to improve food security and self-sufficiency by boosting capacity in agricultural and environmental sciences. The creation of a centre of excellence in 2014 at the International Institute of Water and Environmental Engineering in Ouagadougou within the World Bank project provides essential funding for capacity-building in these priority areas. A dual priority is to promote innovative, effective and accessible health systems. The government wishes to develop, in parallel, applied sciences and technology and social and human sciences. To complement the national research policy, the government has prepared a National Strategy to Popularize Technologies, Inventions and Innovations (2012) and a National Innovation Strategy (2014). Other policies also incorporate science and technology, such as that on Secondary and Higher Education and Scientific Research (2010), the National Policy on Food and Nutrition Security (2014) and the National Programme for the Rural Sector (2011). In 2013, Burkina Faso passed the Science, Technology and Innovation Act establishing three mechanisms for financing research and innovation, a clear indication of high-level commitment. These mechanisms are the National Fund for Education and Research, the National Fund for Research and Innovation for Development and the Forum of Scientific Research and Technological Innovation. Demographics Burkina Faso is an ethnically integrated, secular state where most people are concentrated in the south and centre, where their density sometimes exceeds . Hundreds of thousands of Burkinabè migrate regularly to Ivory Coast and Ghana, mainly for seasonal agricultural work. These flows of workers are affected by external events; the September 2002 coup attempt in Ivory Coast and the ensuing fighting meant that hundreds of thousands of Burkinabè returned to Burkina Faso. The regional economy suffered when they were unable to work. In 2015, most of the population belonged to "one of two West African ethnic cultural groups: the Voltaic and the Mandé. Voltaic Mossi make up about 50% of the population and are descended from warriors who moved to the area from Ghana around 1100, establishing an empire that lasted over 800 years". The total fertility rate of Burkina Faso is 5.93 children born per woman (2014 estimates), the sixth highest in the world. In 2009 the U.S. Department of State's Trafficking in Persons Report reported that slavery in Burkina Faso continued to exist and that Burkinabè children were often the victims. Slavery in the Sahel states in general, is an entrenched institution with a long history that dates back to the trans-Saharan slave trade. In 2018, an estimated 82,000 people in the country were living under "modern slavery" according to the Global Slavery Index. Ethnic groups Burkina Faso's 17.3 million people belong to two major West African ethnic cultural groups: the Voltaic and the Mandé (whose common language is Dioula). The Voltaic Mossi make up about one-half of the population. The Mossi claim descent from warriors who migrated to present-day Burkina Faso from northern Ghana around 1100 AD. They established an empire that lasted more than 800 years. Predominantly farmers, the Mossi kingdom is led by the Mogho Naba, whose court is in Ouagadougou. Languages Burkina Faso is a multilingual country. The official language is French, which was introduced during the colonial period. French is the principal language of administrative, political and judicial institutions, public services, and the press. It is the only language for laws, administration and courts. Altogether, an estimated 69 languages are spoken in the country, of which about 60 languages are indigenous. The Mooré language is the most spoken language in Burkina Faso, spoken by about half the population, mainly in the central region around the capital, Ouagadougou. According to the 2006 census, the languages spoken natively in Burkina Faso were Mooré by 40.5% of the population, Fula by 29.3%, Gourmanché by 6.1%, Bambara by 4.9%, Bissa by 3.2%, Bwamu by 2.1%, Dagara by 2%, San by 1.9%, Lobiri with 1.8%, Lyélé with 1.7%, Bobo and Sénoufo with 1.4% each, Nuni by 1.2%, Dafing by 1.1%, Tamasheq by 1%, Kassem by 0.7%, Gouin by 0.4%, Dogon, Songhai, and Gourounsi by 0.3% each, Ko, Koussassé, Sembla, and Siamou by 0.1% each, other national languages by 5%, other African languages by 0.2%, French (the official language) by 1.3%, and other non-indigenous languages by 0.1%. In the west, Mandé languages are widely spoken, the most predominant being Dioula (also known as Jula or Dyula), others including Bobo, Samo, and Marka. Fula is widespread, particularly in the north. Gourmanché is spoken in the east, while Bissa is spoken in the south. Health In 2016, the average life expectancy was estimated at 60 for males and 61 for females. In 2018, the under-five mortality rate and the infant mortality rate was 76 per 1000 live births. In 2014, the median age of its inhabitants was 17 and the estimated population growth rate was 3.05%. In 2011, health expenditures was 6.5% of GDP; the maternal mortality ratio was estimated at 300 deaths per 100000 live births and the physician density at 0.05 per 1000 population in 2010. In 2012, it was estimated that the adult HIV prevalence rate (ages 15–49) was 1.0%. According to the 2011 UNAIDS Report, HIV prevalence is declining among pregnant women who attend antenatal clinics. According to a 2005 World Health Organization report, an estimated 72.5% of Burkina Faso's girls and women have had female genital mutilation, administered according to traditional rituals. Central government spending on health was 3% in 2001. , studies estimated there were as few as 10 physicians per 100,000 people. In addition, there were 41 nurses and 13 midwives per 100,000 people. Demographic and Health Surveys has completed three surveys in Burkina Faso since 1993, and had another in 2009. A Dengue fever outbreak in 2016 killed 20 patients. Cases of the disease were reported from all 12 districts of Ouagadougou. Religion The government of Burkina Faso's 2019 census reported that 63.8% of the population practice Islam, and that the majority of this group belong to the Sunni branch, while a small minority adheres to Shia Islam. A significant number of Sunni Muslims identify with the Tijaniyah Sufi order. The 2019 census also found that 26.3% of the population are Christians (20.1% being Roman Catholics and 6.2% members of Protestant denominations) and 9.0% follow traditional indigenous beliefs such as the Dogon religion, 0.2% have other religions, and 0.7% have none. Animists are the largest religious group in the country's Sud-Ouest region, forming 48.1% of its total population. Education Education in Burkina Faso is divided into primary, secondary and higher education. High school costs approximately CFA 25,000 (US$50) per year, which is far above the means of most Burkinabè families. Boys receive preference in schooling; as such, girls' education and literacy rates are far lower than their male counterparts. An increase in girls' schooling has been observed because of the government's policy of making school cheaper for girls and granting them more scholarships. To proceed from primary to middle school, middle to high school or high school to college, national exams must be passed. Institutions of higher education include the University of Ouagadougou, The Polytechnic University of Bobo-Dioulasso, and the University of Koudougou, which is also a teacher training institution. There are some small private colleges in the capital city of Ouagadougou but these are affordable to only a small portion of the population. There is also the International School of Ouagadougou (ISO), an American-based private school located in Ouagadougou. The 2008 UN Development Program Report ranked Burkina Faso as the country with the lowest level of literacy in the world, despite a concerted effort to double its literacy rate from 12.8% in 1990 to 25.3% in 2008. Culture Literature in Burkina Faso is based on the oral tradition, which remains important. In 1934, during French occupation, Dim-Dolobsom Ouedraogo published his Maximes, pensées et devinettes mossi (Maxims, Thoughts and Riddles of the Mossi), a record of the oral history of the Mossi people. The oral tradition continued to have an influence on Burkinabè writers in the post-independence Burkina Faso of the 1960s, such as Nazi Boni and Roger Nikiema. The 1960s saw a growth in the number of playwrights being published. Since the 1970s, literature has developed in Burkina Faso with many more writers being published. The theatre of Burkina Faso combines traditional Burkinabè performance with the colonial influences and post-colonial efforts to educate rural people to produce a distinctive national theatre. Traditional ritual ceremonies of the many ethnic groups in Burkina Faso have long involved dancing with masks. Western-style theatre became common during colonial times, heavily influenced by French theatre. With independence came a new style of theatre inspired by forum theatre aimed at educating and entertaining Burkina Faso's rural people. Slam poetry is increasing in popularity in the country, in part due to the efforts of slam poet Malika Outtara. She uses her skills to raise awareness around issues such as blood donation, albinism and the impact of COVID-19. Arts and crafts In addition to several rich traditional artistic heritages among the peoples, there is a large artist community in Burkina Faso, especially in Ouagadougou. Much of the crafts produced are for the country's growing tourist industry. Burkina Faso also hosts the International Art and Craft Fair, Ouagadougou. It is better known by its French name as SIAO, Le Salon International de l' Artisanat de Ouagadougou, and is one of the most important African handicraft fairs. Cuisine Typical of West African cuisine, Burkina Faso's cuisine is based on staple foods of sorghum, millet, rice, maize, peanuts, potatoes, beans, yams and okra. The most common sources of animal protein are chicken, chicken eggs and freshwater fish. A typical Burkinabè beverage is Banji or Palm Wine, which is fermented palm sap; and Zoom-kom, or "grain water" purportedly the national drink of Burkina Faso. Zoom-kom is milky-looking and whitish, having a water and cereal base, best drunk with ice cubes. In the more rural regions, in the outskirts of Burkina, you would find Dolo, which is drink made from fermented millet. Cinema The cinema of Burkina Faso is an important part of the West African film industry and African film as a whole. Burkina's contribution to African cinema started with the establishment of the film festival FESPACO (Festival Panafricain du Cinéma et de la Télévision de Ouagadougou), which was launched as a film week in 1969. Many of the nation's filmmakers are known internationally and have won international prizes. For many years the headquarters of the Federation of Panafrican Filmmakers (FEPACI) was in Ouagadougou, rescued in 1983 from a period of moribund inactivity by the enthusiastic support and funding of President Sankara. (In 2006 the Secretariat of FEPACI moved to South Africa, but the headquarters of the organization is still in Ouagadougou.) Among the best known directors from Burkina Faso are Gaston Kaboré, Idrissa Ouedraogo and Dani Kouyate. Burkina produces popular television series such as Les Bobodiouf. Internationally known filmmakers such as Ouedraogo, Kabore, Yameogo, and Kouyate make popular television series. Sports Sport in Burkina Faso is widespread and includes football, basketball, cycling, rugby union, handball, tennis, boxing and martial arts. Football is the most popular sport in Burkina Faso, played both professionally, and informally in towns and villages across the country. The national team is nicknamed "Les Etalons" ("the Stallions") in reference to the legendary horse of Princess Yennenga. In 1998, Burkina Faso hosted the Africa Cup of Nations for which the Omnisport Stadium in Bobo-Dioulasso was built. Burkina Faso qualified for the 2013 African Cup of Nations in South Africa and reached the final, but then lost to Nigeria 0–1. The country has never qualified for a FIFA World Cup. Basketball is another sport which enjoys much popularity for both men and women. The country's men's national team had its most successful year in 2013 when it qualified for the AfroBasket, the continent's prime basketball event. At the 2020 Summer Olympics, the athlete Hugues Fabrice Zango won Burkina Faso's first Olympic medal, winning bronze in the men's triple jump. Cricket is also picking up in Burkina Faso with Cricket Burkina Faso running a 10 club league. Music The music of Burkina Faso includes the folk music of 60 different ethnic groups. The Mossi people, centrally located around the capital, Ouagadougou, account for 40% of the population while, to the south, Gurunsi, Gurma, Dagaaba and Lobi populations, speaking Gur languages closely related to the Mossi language, extend into the coastal states. In the north and east the Fulani of the Sahel preponderate, while in the south and west the Mande languages are common; Samo, Bissa, Bobo, Senufo and Marka. Burkinabé traditional music has continued to thrive and musical output remains quite diverse. Popular music is mostly in French: Burkina Faso has yet to produce a major pan-African success. Media The nation's principal media outlet is its state-sponsored combined television and radio service, Radiodiffusion-Télévision Burkina (RTB). RTB broadcasts on two medium-wave (AM) and several FM frequencies. Besides RTB, there are privately owned sports, cultural, music, and religious FM radio stations. RTB maintains a worldwide short-wave news broadcast (Radio Nationale Burkina) in the French language from the capital at Ouagadougou using a 100 kW transmitter on 4.815 and 5.030 MHz. Attempts to develop an independent press and media in Burkina Faso have been intermittent. In 1998, investigative journalist Norbert Zongo, his brother Ernest, his driver, and another man were assassinated by unknown assailants, and the bodies burned. The crime was never solved. However, an independent Commission of Inquiry later concluded that Norbert Zongo was killed for political reasons because of his investigative work into the death of David Ouedraogo, a chauffeur who worked for François Compaoré, President Blaise Compaoré's brother. In January 1999, François Compaoré was charged with the murder of David Ouedraogo, who had died as a result of torture in January 1998. The charges were later dropped by a military tribunal after an appeal. In August 2000, five members of the President's personal security guard detail (Régiment de la Sécurité Présidentielle, or RSP) were charged with the murder of Ouedraogo. RSP members Marcel Kafando, Edmond Koama, and Ousseini Yaro, investigated as suspects in the Norbert Zongo assassination, were convicted in the Ouedraogo case and sentenced to lengthy prison terms. Since the death of Norbert Zongo, several protests regarding the Zongo investigation and treatment of journalists have been prevented or dispersed by government police and security forces. In April 2007, popular radio reggae host Karim Sama, whose programs feature reggae songs interspersed with critical commentary on alleged government injustice and corruption, received several death threats. Sama's personal car was later burned outside the private radio station Ouaga FM by unknown vandals. In response, the Committee to Protect Journalists (CPJ) wrote to President Compaoré to request his government investigate the sending of e-mailed death threats to journalists and radio commentators in Burkina Faso who were critical of the government. In December 2008, police in Ouagadougou questioned leaders of a protest march that called for a renewed investigation into the unsolved Zongo assassination. Among the marchers was Jean-Claude Meda, the president of the Association of Journalists of Burkina Faso. Cultural festivals and events Every two years, Ouagadougou hosts the Panafrican Film and Television Festival of Ouagadougou (FESPACO), the largest African cinema festival on the continent (February, odd years). Held every two years since 1988, the International Art and Craft Fair, Ouagadougou (SIAO), is one of Africa's most important trade shows for art and handicrafts (late October-early November, even years). Also every two years, the Symposium de sculpture sur granit de Laongo takes place on a site located about from Ouagadougou, in the province of Oubritenga. The National Culture Week of Burkina Faso, better known by its French name La Semaine Nationale de la culture (SNC), is one of the most important cultural activities of Burkina Faso. It is a biennial event which takes place every two years in Bobo Dioulasso, the second-largest city in the country. The Festival International des Masques et des Arts (FESTIMA), celebrating traditional masks, is held every two years in Dédougou.

Telecommunications in Belarus

Telecommunications in Belarus involves the availability and use of electronic devices and services, such as the telephone, television, radio or computer, for the purpose of communication. Telephone system Telephone lines in use: 3,9741 million (2011). Mobile/cellular: 11,559,473 subscribers (Q1 2019). The phone calling code for Belarus is +375. The Ministry of Telecommunications controls all telecommunications originating within the country through its carrier unitary enterprise, Beltelecom. Minsk has a digital metropolitan network; waiting lists for telephones are long; fixed line penetration is improving although rural areas continue to be underserved; intercity – Belarus has developed a fibre-optic backbone system presently serving at least 13 major cities (1998). Belarus's fibre optics form synchronous digital hierarchy rings through other countries' systems. International connection Belarus is a member of the Trans-European Line (TEL), Trans-Asia-Europe Fibre-Optic Line (TAE) and has access to the Trans-Siberia Line (TSL); three fibre-optic segments provide connectivity to Latvia, Poland, Russia, and Ukraine; worldwide service is available to Belarus through this infrastructure; Intelsat, Eutelsat, and Intersputnik earth stations. In 2006 it was announced that Belarus and Russia completed the second broadband link between the two countries, the Yartsevo-Vitebsk cable. The capacity of this high speed terrestrial link which based on DWDM and STM technology is 400Gbit/s with the ability to upgrade in the future. Cellular communications Belarus has 3 GSM/UMTS operators – A1, MTS, life:). For 4G data operators use the infrastructure managed by state operator beCloud, VoLTE service currently is offered only with A1. Radio and television Television broadcast stations: 100 of which 59 are privately owned. Belarus has switched from an analog to digital broadcast television. The process finished in May 2015. Belarus broadcasts according to the DVB-T2 standard with MPEG-4 compression. Radio broadcast stations: 173 with 24 privately owned, including 30 FM stations. Radios: 3.02 million (1997). Internet Country code: .by The state telecom monopoly, Beltelecom, holds the exclusive interconnection with Internet providers outside of Belarus. Beltelecom owns all the backbone channels that linked to the Lattelecom, TEO LT, Tata Communications (former Teleglobe), Synterra, Rostelecom, Transtelekom and MTS ISP's. Beltelecom is the only operator licensed to provide commercial VoIP services in Belarus. Until 2005–2006 broadband access (mostly using ADSL) was available only in a few major cities in Belarus. In Minsk there were a dozen privately owned ISP's and in some larger cities Beltelecom's broadband was available. Outside these cities the only options for Internet access were dial-up from Beltelecom or GPRS/cdma2000 from mobile operators. In 2006 Beltelecom introduced a new trademark, Byfly, for its ADSL access. As of 2008 Byfly was available in all administrative centres of Belarus. Other ISPs are expanding their broadband networks beyond Minsk as well. Internet use: According to a 2006 survey of 1,500 adults by Satio, a third of Belarusians use the Internet—38% of the urban population and 16% of the rural population. A 2006 study by the United Nations Conference on Trade and Development indicates 56.5% of Belarus' population were internet-users. The International Telecommunication Union showed Internet penetration (Internet users per 100 population) in 2009 at 27% for Belarus, 42% for Serbia, 37% for Romania, 29% for Russia, and 17% for Ukraine. According to Internet World Stats, Internet penetration in June 2010 was 47.5%. For comparison, Internet penetration in the Ukraine was 33.7%, in Romania 35.5%, Russia 42.8%, and Serbia 55.9%. The most active Internet users in Belarus belong to the 17–22 age group (38 percent), followed by users in the 23–29 age group. Internet access in Belarus is predominantly urban, with 60 percent of users living in the capital Minsk. The profile of the average Internet user is male, university educated, living in the capital, and working in a state enterprise. The Ministry for Statistics and Analysis estimates that one in four families in Belarus owns a computer at home. The popularity of Internet cafés has fallen in recent years, as most users prefer to access the Internet from home or work. Russian is the most widely used language by Belarusians on the Internet, followed by Belarusian, English, and Polish. In mid-2009 there were more than 22,300 Belarusian Web sites, of which roughly 13,500 domain names were registered with the top-level domain name ".by". In June 2011 E-Belarus.org listed: 2 ISPs in the Brest region, 4 in the Gomel region, 1 in the Grodno region, 26 in the Minsk region, 1 in the Mogilev region, and 1 in the Vitebsk region 4 ADSL providers 3 technology parks 2 educational networks more than 30 Internet cafes and Wi-Fi Hotspots Censorship and media freedom Many western human rights groups state that civil rights and free expression are severely limited in Belarus, though there are some individuals and groups that refuse to be controlled and some journalists have disappeared. Because the Belarus government limits freedom of expression, several opposition media outlets are broadcast from nearby countries to help provide Belarusians an alternative points of view. This includes the Polish state-owned Belsat TV station and European Radio for Belarus (Eŭrapéjskaje Rádyjo dla Biełarúsi) Reporters Without Borders ranked Belarus 157th out of 178 countries in its 2014 Press Freedom Index. By comparison, the same index ranked neighbor Ukraine, 126th and Russia, 148th. In the 2011 Freedom House Freedom of the Press report, Belarus scored 92 on a scale from 10 (most free) to 99 (least free), because the government allegedly systematically curtails press freedom. This score placed Belarus 9th from the bottom of the 196 countries included in the report and earned the country a "Not Free" status.

Armed Forces of Belarus

The Armed Forces of the Republic of Belarus (; ) are the military forces of Belarus. It consists of the Ground Forces and the Air Force and Air Defence Forces, all under the command of the Ministry of Defence. As a landlocked country, Belarus has no navy. In 2017, IISS estimated that personnel in the armed forces numbered 48,000. Most soldiers are conscripts serving for a period of 18 months, although there is an alternative service option. Belarus conducted military reforms in the early 2000s which reshaped its armed forces as a relatively effective force for a small state in somewhat difficult economic conditions. History The Belarusian People's Republic of March 1918 to 1919 did not have time to create armed forces in its brief existence, although attempts to create a military have been documented. Until 1991, the Soviet Belorussian Military District comprised the 5th Guards Tank Army (HQ Bobruisk), the 7th Tank Army (HQ Borisov), the 28th Army (HQ Grodno), the 120th Guards Motor Rifle Division, the 72nd Guards District Training Center and logistical units and formations. Additionally, the Belorussian SSR hosted the 103rd Guards Airborne Division, the 38th Guards Airborne Brigade, the 11th Air Defence Corps of the 2nd Air Defence Army, and the 26th Air Army, as well as units and formations of the Strategic Rocket Forces, Long Range Aviation, the Navy, and special forces. In late 1991 the 5th Guards Tank Army comprised the 30th Guards Motor Rifle Division, newly arrived from Czechoslovakia, and the 193rd Tank Division, plus two armament and equipment storage bases (the former 8th Guards and 29th Tank Divisions), and army troops. The 7th Tank Army comprised the 3rd Guards Tank Division, 34th, and 37th Guards Tank Divisions, plus army troops. The 28th Army comprised two divisions, the 6th Guards Tank and 50th Guards Motor Rifle, the 6314th Equipment Storage Base at Slonim, and the 5356th Base for Storage of Weapons and Equipment, formerly a low-status mobilisation division. Also arriving from the Southern Group of Forces in Hungary was the 19th Guards Tank Division. On September 20, 1991, the Supreme Soviet of Belarus passed resolution "On the formation of the Armed Forces of the Republic of Belarus" and on January 11, 1992, resolution "On the Armed Forces deployed in the territory of the Republic of Belarus." On March 18, 1992, the parliament passed resolution "On the Armed Forces of the Republic of Belarus" that bound the government "to start the formation of the Armed Forces of the Republic of Belarus as of March 20, 1992" and "to submit to the Supreme Soviet for approval the suggested structure of the Armed Forces, their size and order of their material and technical supplies". On May 6, 1992, the Belorussian Military District was abolished. The Belarusian Ministry of Defence and the Main Staff were formed from its resources. The former first deputy commander and military district Chief of Staff, Lieutenant-General Pavel Kozlovskiy, was appointed Minister of Defence on 22 April 1992, taking over from acting Minister of Defence Colonel-General Petr Chaus. On 8 September 1992, the Minsk Higher Military Engineering School and the Minsk Higher Military Command School (now the unified Military Academy of Belarus) were the first to take the military oath of allegiance to the armed forces, with their induction ceremony being held on Independence Square in the presence of defense minister Kozlovskii. This was done to commemorate anniversary of the Lithuanian-Polish victory at the Battle of Orsha, which was considered to be a Day of Belarusian Military Glory. On August 17, 1992, personnel from the United States Department of Defense made a Conventional Forces in Europe Treaty inspection of an installation in Urechye (near Minsk). The 969th Central Base for Reserve Tanks, and two elements of the 30th Guards Motor Rifle Division: the 30th Guards Tank Regiment and the 20th independent Reconnaissance Battalion were the three units at the site. On November 3, 1992, Belarus passed the law "On the Armed Forces of the Republic of Belarus" defining the status, structure and guiding principles of the Armed Forces. After the introduction of presidency the law was amended twice: on September 4, 1996, and on November 9, 1999, but on the whole the law retains its initial contents. On January 1, 1993, all service personnel on Belarusian soil were required to either take an oath of loyalty to Belarus, or leave. This oath however did not alleviate concerns regarding loyalty to Russia in time of crisis, especially since nearly 50% of all military personnel were ethnically Russian in the end of 1992. In June 1995, President Alexander Lukashenko issued a decree on the Mobile Forces. By June 1996, they comprised a headquarters in Vitebsk, two brigades drawn from the 103rd Guards Airborne Division, the 38th Independent Mobile Brigade (Brest, Belarus), an air transport regiment, and communications, logistics, and engineer units. Membership in the Commonwealth of Independent States, as well as the 1996 treaty on the Union of Russia and Belarus and the Treaty of the Formation of a Union State in 1999, confirmed a close partnership with Russia. Much of the air defence system was integrated into the Russian air defence network, and in 2006 the two nations signed an agreement on the creation of a unified air defence system. Structure Belarus government websites say that the Ministry of Defence of the Republic of Belarus is supported by Central Command Support Elements and the General Staff of the Armed Forces. Combat Support Elements of the Armed Forces included Reconnaissance, Electronic Warfare, Signals, Engineer, NBC Defence, Navigation and Topography, and Maintenance organisations. Logistic Elements of the Armed Forces provided Material Support, Logistic Support, Medical Support, Veterinarian Support, and Military Construction. In 1995 the Military Academy of Belarus was set up on the basis of two military educational institutions – the Minsk Air Defence and Rocket School of the Soviet Air Defence Forces and the Minsk Higher Military Command School. Its 10 departments train officers of 38 specialties for practically all arms of service. Also in 1995 it was given the status of a government institution of secondary special military education for young men. Branches Ground Forces A Library of Congress study of national ground forces said that in 1994 Belarus had ground forces of 52,500. They were organized into three corps headquarters, two motor divisions, one airborne division, the 51st Guards Artillery Division at Osipovichi, three mechanized divisions, one airborne brigade, three surface-to-surface missile brigades, two antitank brigades, one special duties brigade, and seven anti-aircraft missile brigades. Equipment included 3,108 main battle tanks (seventy-nine T-54, 639 T-55, 291 T-62, 299 T-64, eight T-80, and 1,800 T-72), 419 medium-range launchers, sixty surface to-surface missiles, and 350 surface-to-air missiles. In 1993 the 7th Tank Army was reorganised as the 7th Army Corps. In 1994 the 7th Army Corps was redesignated as the 65th Army Corps, still located at Borisov. By January 1, 1995, the composition of the Belarusian ground forces had changed. The Library of Congress study estimated at the time that Ministry of Defence forces included the 103rd Guards Airborne Division and the 38th Separate Assault-Landing Brigade; the 28th Army Corps (Grodno Region and Brest Region), composed of headquarters at Grodno, the 6th Guards Kiev-Berlin Mechanised Brigade, the 11th Guards Mechanised Brigade, the 50th Separate Mechanised Infantry Brigade, the Armament and Equipment base, and corps units (missile troops, antiaircraft, chemical and engineer troops, signals, and rear services); the 65th Army Corps (Minsk and Vitebsk Regions), composed of headquarters at Borisov, three armament and equipment bases, and corps units; and the 5th Guards Army Corps (Minsk and Mahilyow regions) made up of headquarters at Babruysk, the 30th Separate Motor Rifle Brigade, two Armament and Equipment bases, and corps units. Actually, the 103rd Guards Airborne Division had been reorganized as Headquarters, Mobile Forces, in 1993. On 1 August 1996 the 51st Guards Artillery Division was reorganised as the 51st Guards Central Group of Artillery, still located at Osipovichi. On 21 December 2001, a major reorganisation of the Ground Forces produced two operational-territorial commands, formed from two former corps headquarters. All Belarus ground forces were now grouped within these two commands, the Western Operational Command at Grodno, former from the previous 28th Army Corps, the former Soviet 28th Army, and the North Western Operational Command, the former 65th Army Corps, at Barysaw (Borisov). Since about 2001, territorial defence forces, which as of 2002 number around 150,000, have been forming, organised into battalions, companies, and platoons spread across Belarus. In 2007, the Land Forces consisted of 29,600 soldiers (6th Guards Mechanised Brigade (Grodno), 11th Guards Mechanized Brigade at Slonim, the 120th Guards Mechanised Brigade (Minsk), 38th and 103rd Mobile Brigades (organized similarly to Soviet airborne regiments, not all of them are equipped with BMD-1), 5th Spetsnaz Brigade (Maryina Horka), five artillery brigades and four regiments, two MRL regiments, 15th, 29th, 115th, 120th and 302nd SAM Brigades, two SSM brigades, two brigades and one regiment of engineers, 8th independent NBC Brigade, two signals brigades, 40th independent NBC battalion. Army equipment includes 1800 main battle tanks (MBT) and 2600 AFV/APC. The weapons and equipment storage bases include the 50th (Brest), 19th, 34th & 37th (former tank divisions), 3rd, and 28th (Baranovichi). Weapons storage bases that have been disbanded include the 29th, 30th, 193rd, and the storage base that used to be the 8th Guards Tank Division at Marina Gorka. In 2012 it was reported that there were six mechanised brigades in the Ground Forces: three full-strength, the 6th (Grodno), 11th (Slonim), and 120th Guards Mechanised Brigade at Minsk. The others were at reduced strength, where there was one battalion, the 19th (Zaslonova), 37th, and 50th (Baranovichi). By 2017, the number of mechanised brigades had been further reduced to four, with two at full strength and two at reduced strength. Air Force and Air Defence Forces The 28th Fighter Aviation Regiment, 2nd Air Defence Corps, Moscow Air Defence District was stationed in Krichev in Mogilev Oblast, and disbanded in 1993. In 2007 the Air Force and Air Defence Force of Belarus (AF & ADF) consisted of 18,170 personnel (two fighter/interceptor bases, four FGA/reconnaissance squadrons, one transport air base, training aircraft, and attack and support helicopters, SAM units). Air Force equipment included in 2004 260 fighter-ground attack/training aircraft and 80 attack helicopters. According to Belarus government websites, the Air Forces now have two commands, the Western Operational-Tactical Command and the North-Western Operational-Tactical Command. The 61st and 927th Air Bases have now merged into the 61st (fighter) Air Base at Baranovichi, flying MiG-29s, and the 206th Air Base (Ross) has merged into the 116th Guards Assault Air Base at Lida, flying Su-25s. Independent forces Special Forces The Special Forces of Belarus is the airmobile and strategic deterrence force. It has been a participant in conflicts such as the United Nations Interim Force in Lebanon and the Libyan Civil War (2011). Transport Troops The Belarusian Transport Troops is responsible for the movement of personnel and material by truck, rail, and air. It is also designed to carry the tasks of the transport support of the military formations from other service branches. General leadership is exercised by the Minister of Defense, while direct control is carried out by the Head of the Transport Support Department, a position that reports directly to the President. Territorial Forces The Territorial Forces (, ) are a homeland defence organization in the armed forces. It is managed by the Department of the Territorial Forces, being a support department of the Ministry of Defence of Belarus and is operated by the General Staff. It is currently located on Kommunisticheskaya Street in Minsk. The current head of the department of territorial forces is Colonel Andrei Paseko. The Territorial Defence system was established in the early 2000s. Over 120,000 troops constitute the size of the Territorial Forces, which is twice as much as it serves in the regular duty military. During an address by President Alexander Lukashenko on 18 February 2016, he announced the allocation of arms and to the territorial forces and the minimum and maximum amount of district troops ranging from one company and a battalion. Personnel of these units are recruited from residents of their respective administrative-territorial regions. Specialized forces Special troops are designed to support the combat activities of the Ground Forces and solve their inherent tasks. They include formations and military units of intelligence, communications, engineering, radiation, chemical and biological defense, electronic warfare, navigation and topographic. Electronic Warfare Troops Signal Corps Engineer troops NBC Protection Troops Topographic Navigation Service Security forces Internal Troops The Internal Troops of Belarus were formed from the former Soviet Internal Troops after the collapse of the Soviet Union. They consist of three independent brigades and seven independent battalions (consecutively numbered). Border Guard Service The Border Guard Service is the paramilitary force of the State Border Committee of the Republic of Belarus. It covers the borders with Russia, Ukraine, Poland, Lithuania and Latvia. Manpower The Government Directive of 20 March 1992 'On the Establishment of the Armed Forces of the Republic of Belarus' founded the Belarusian army. The Soviet troops of the BMD were smoothly converted into Belarusian military units. Yet one of the first tasks of the Belarusian government was a reduction in its numbers. 240,000 soldiers and officers were serving in the Belarusian Military District. By early 2013 the numbers of military personnel had been scaled down nearly fourfold since 1991. In February 2014, Belorusskaya Voyennaya Gazeta, the official publication of the Ministry of Defense revealed that the Belarusian Armed Forces contains about 59,500 personnel, including 46,000 soldiers and 13,000 civilians. Personnel Military commandants The military commandants of the Armed Forces of Belarus are regional administrations tasked with overseeing Belarusian regiments in the commandant's territory. Units are assigned to a specific commandant based on their location. There are 6 military commandants in the Belarusian Armed Forces. Units under the command of commandants include military police, honour guards and military bands. Military education Military Academy of Belarus Ministry of the Interior Academy of Belarus Border Guard Service Institute of Belarus Military Institute of the Belarusian State Medical University Military Faculty of the Belarusian State University – The faculty was established on 4 November 1926, by order of the Revolutionary Military Council. In 1941, at the beginning of the Great Patriotic War, military training classes were interrupted only to be resumed in 1943. In the post-war and subsequent years, the military department continued to train reserve officers from among the students in the required military accounting specialties. In 2003, the military department was reorganized into the modern military faculty of Belarusian State University. Military Faculty of the Belarusian State University of Informatics and Radioelectronics Military Faculty of the Belarusian National Technical University Military Faculty of the Grodno State University Military Faculty of the Belarusian State University of Transport Military Faculty of the Belarusian State Academy of Aviation Equipment The military forces of Belarus are almost exclusively armed with Soviet-era equipment inherited from the Soviet Union. Although large in numbers, some Western experts consider some of it outdated. "The Belarusian armed forces receive around 100 brand-new and upgraded systems a year", said in late July 2018, Belarusian Deputy Minister of Defence for Armament and Chief of Armament Major General Sergei Simonenko. The MBTs are of Russian type T-72, T-62, and T-55, the APCs and IFVs are of Russian type MT-LB, BMP-2, BMP-1, and the BMD-1, and Russian type trucks are the GAZ-66 and the KAMAZ-6560. While the IISS Military Balance 2016 listed 69 T-80s in service, by 2018 the listing had been removed, and the only MBTs listed were 527 T-72 as well as 5 T-72B3. The Air Force is equipped with MiG-29 fighters, Su-25 attack aircraft, as well as Mi-8, Mi-24, and some old, Polish built Mi-2 helicopters. In December 2005, Belarus bought 10 L-39C jet trainer aircraft from Ukraine, and in 2017 a contract have been signed to buy 12 Su-30SM fighters. In 2006, four batteries (divizions in Russian terminology; about six systems each) of S-300 anti-aircraft systems were acquired from Russia to reinforce the Joint CIS Air Defense System. The Military Balance 2018 listed a brigade with the S-300P and a brigade with the S-300V (SA-12A Gladiator/SA-12B Giant). Moscow and Minsk signed contracts in 2021 for the supply of fighters, helicopters, air defense systems and other weapons to Belarus. S-400 air defense systems and 9K720 Iskander tactical ballistic missiles were delivered in 2022. It was also reported that almost every company was equipped with quadcopters. Military cooperation CSTO The armed forces took part in a joint CSTO military intervention in Kazakhstan during the 2022 Kazakh unrest. Military advisors The armed forces have sent their military specialists to countries such as Côte d'Ivoire, Venezuela, Libya, Yemen and the Democratic Republic of the Congo, acting both officially and secretly. In Belarus, they have previously trained military personnel from the Nigerian Army. In 2014 and 2015, the special forces of the Nigerian Army were trained on the territory of Belarus, with the Belarusians training the Nigerians in counterterrorism. In 2007, an agreement was signed in Caracas with Venezuela, according to which Belarusian military specialists for the National Bolivarian Armed Forces of Venezuela were developing a unified air defense and electronic warfare system. The following year, the first ten servicemen went to the country, with Lieutenant-General Oleg Paferov being appointed as the officer responsible for the activities of the advisers. A contingent of about 500 military advisers was also present in Libya during the First Libyan Civil War, supporting the government of Muammar Gaddafi. As of autumn 2013, there were at least two Belarusian advisers in Yemen at the Ministry of Defense. On November 26 of the same year, during an attack on a hotel in Sana'a, a Belarusian was killed and another was wounded. In February 2020, a dozen Belarusian military instructors arrived in Abidjan (Côte d'Ivoire), where they were stationed at the Agban military base, which is occupied by one of the country's national gendarmerie units. Institutions and special units of the armed forces Museum of Military History of Belarus The Museum of Military History of Belarus () is located in the Pyershamayski District of Minsk. It was established as the Museum of the History of the Belarusian Military District, opened in Minsk on February 21, 1978. In July 1993, it was converted into a museum on the military history of Belarus. The exhibits are the same as before the collapse of the USSR, with a small section on the medieval history of the Grand Duchy of Lithuania having since been added. Its collection numbers over 18 thousand exhibits. The most ancient of them date back to the 6th century. Drama Theatre of the Belarusian Army Belarusian Union of Officers The Public Association "Belarusian Union of Officers" (hereinafter referred to as BSO) is a public association of officers and warrant officers who are on active duty and in retirement. It was established on 20 September 1992 at its founding congress. On September 18, 1993, Deputy of the Supreme Soviet Alexander Lukashenko took part in the 2nd Congress. From October 2005 to January 2015, the Republican Council of the BSO was headed by retired Lieutenant General E. Mikulchik, and until November 2017 was led by retired Major General V. Bamburov.

Economy of Bosnia and Herzegovina

The economy of Bosnia and Herzegovina is a transitional, upper middle income economy. Bosnia and Herzegovina declared independence from socialist Yugoslavia on 1 March 1992. The main trading partners are Germany, Italy, Austria, Turkey and other neighboring Balkan countries. Overview Bosnia and Herzegovina is an upper middle-income country which has accomplished a great deal since the mid-1990s. Today, it is an EU potential candidate country and is now embarking on a new growth model amid a period of slow growth and the global financial crisis. Bosnia and Herzegovina is a small, open economy, dominated by services, which accounted for 55% of gross domestic product (GDP) in 2016, with a moderately developed industrial and manufacturing sector (23% and 12%, respectively), and a limited agricultural base (about 6% of GDP). The konvertibilna marka (convertible mark or BAM) - the national currency introduced in 1998 - is pegged to the euro, and confidence in the currency and the banking sector has increased. Implementation of privatization, however, has been slow, and local entities only reluctantly support national-level institutions. Banking reform accelerated in 2001 as all ; foreign banks, primarily from Western Europe, now control most of the banking sector. A sizable current account deficit and very high unemployment rate remain the two most serious economic problems. The country receives substantial amounts of reconstruction assistance and humanitarian aid from the international community but will have to prepare for an era of declining assistance. The United States Embassy in Sarajevo, Bosnia and Herzegovina produces the Country Commercial Guide – an annual report that delivers a comprehensive look at Bosnia and Herzegovina's commercial and economic environment, using economic, political, and market analysis. According to Serbian American economist, Branko Milanović, Bosnia and Herzegovina did the best job in the transition from socialism to capitalism when compared to the other republics of the former Yugoslavia. From 1985 until 2021, Bosnia and Herzegovina performed the best on the annual average GDP growth per capita (1.6%), Slovenia (1.4%), Croatia (1%), Serbia without Kosovo (0.9%) and North Macedonia (0.5%). Brief economic history until the 1990s At the time of the Socialist Federal Republic of Yugoslavia (SFRY), Bosnia and Herzegovina was an important mineral processing centre and provided the other republics with basic mineral commodities in exchange for current consumption goods. While large amounts of public capital investments poured in during the 1970s, productivity levels remained low, often due to the limited capacity of public managers. Under former republican premier Džemal Bijedić, and Yugoslav president Tito, metal-product industries were promoted in the republic, resulting in the development of a large share of Yugoslavia's metal products plants. Merging small firms into larger agglomerates was a common practice in the SFRY to preserve employment levels. As a result, four large conglomerates emerged in Bosnia and Herzegovina over time: Energoinvest (energy sector), Unis (automotive and defence industry, which partnered with Volkswagen in the early 1970s), Šipad (wood processing) and RMK Zenica (steel industry, later acquired by ArcelorMittal). Construction and defence were important industries of the Bosnian economy, despite their low efficiency and, ultimately, supply excess. The defence industry was particularly developed in the southern districts and around Mostar, which was also a relevant metallurgical centre (Aluminij Mostar). Machinery production was concentrated in the north, particularly around Banja Luka. The Tuzla district was renowned for its chemical industry. The automotive industry, which developed in the 1950s with the production of vehicle components, extended later on to passenger and commercial vehicles, with plants in Sarajevo, Mostar and Banja Luka. Agriculture was not highly developed, despite its importance for employment and the presence of the large Agrokomerc conglomerate based at the north-west border with Croatia. Tito had pushed the development of metal industries, and electro-energetic sector, in the republic with the result that Bosnia and Herzegovina were a host of large numbers of industrial firms. Some of them were worked with World brand names, companies like Coca-Cola, Pepsi, Marlboro, Volkswagen and SKF. Big Companies like Energoinvest, UNIS, Hidrogradnja, Vranica, RMK Zenica, TAS Sarajevo, FAMOS Sarajevo and BNT Novi Travnik, have yearly income in billions of USD$ at that time. Building sector companies bringing large amounts of income in USD$. Unemployment at that time is very low. Work force is highly skilled, with highly professional, educated managers, engineers, science experts, which use western world's newest technologies in large scale areas. Before the war, Yugoslav premier Ante Marković, made some preparations for privatization, in economy, finance, and industry sectors, but the war ceased development in these actions. The economy suffered heavily from the war in Bosnia and Herzegovina, with over €200 billion in material damages and GDP (excluding services) reduced by 90% between 1990 and 1995. Today, most of the above-mentioned companies have been privatised. The economy remains fragile, primarily consumption driven and vulnerable to external fluctuations. This was seen with the global economic crisis, which pushed Bosnia and Herzegovina into recession in 2009 and 2012 (with GDP growth of -3% and -0.8%, respectively) and severe floods in 2014, which caused damage of approximately 15% of GDP. Since 2015, annual GDP growth has increased to more than 3%. Still, the country registered a current account deficit of 4.7% of GDP in 2017, decreasing from 5.3% in 2015, resulting from a reduction in its trade deficit, which nevertheless remains large (17.4% of GDP in 2017). A Central Bank of Bosnia and Herzegovina was established in late 1997, debt negotiations were held with the London Club in December 1997 and with the Paris Club in October 1998, and a new currency, the Bosnia and Herzegovina convertible mark, was introduced in mid-1998. In 1999, the Convertible Mark gained wider acceptance, and the Central Bank dramatically increased its reserve holdings. Due to Bosnia's strict currency board regime attaching the Bosnian mark to the Euro, inflation has remained low in the entire country. With an uneasy peace in place, output recovered in 1996–99 at high percentage rates from a low base; but output growth slowed in 2000–02. The country receives substantial amounts of reconstruction assistance and humanitarian aid from the international community. Support for East European Democracy (SEED) assistance accounts for 20%-25% of economic growth in Bosnia and Herzegovina. However, growth has been uneven throughout the post-war period, with the Federation outpacing the RS. According to World Bank estimates, GDP growth was 62% in the Federation and 25% in the RS in 1996, 35% in the Federation and flat in the RS in 1997, and continued growth in the Federation in 1998. Movement has been slow, but considerable progress has been made in economic reform since peace was re-established. Banking reform lagged, as did the implementation of privatization. Many companies (mainly factories) that were privatized faced massive problems, causing the owners to reduce salaries and deny the workers their salaries, and some of the new owners and tycoons destroy that factories.

Sports-related tourism uses the legacy facilities of the 1984 Winter Olympics, especially the skiing facilities on the nearby mountains of Bjelašnica, Igman, Jahorina, Trebević, and Treskavica. Sarajevo's 600 years of history, influenced by both Western and Eastern empires, is also a strong tourist attraction. Sarajevo has hosted travellers for centuries, because it was an important trading center during the Ottoman and Austria-Hungarian empires. Today, Sarajevo is one of the fastest developing cities in the region. Various new modern buildings have been built, most significantly the Bosmal City Center, ARIA Centar and the Avaz Twist Tower, which is one of the tallest skyscraper in the Balkans. A new highway was recently (2006–2011) completed between Sarajevo and the city of Kakanj. Due to growth in population, tourism and airport traffic the service sector in the city is developing fast and welcoming new investors from various businesses. Sarajevo has one of the most representable commercial infrastructures in South-East Europe. The Sarajevo City Center is one of the biggest shopping centres in South-East Europe, after its completion in 2014.

In 2011, Sarajevo's GDP was estimated to be 16.76 billion US$ by the Central Bank of Bosnia, comprising 37% of the total GDP of the country. Mostar Mostar's economy relies heavily on tourism, aluminum and metal industry, banking services and telecommunication sector. The city is the seat of some of the country's largest corporations. Along with Sarajevo, it is the largest financial center in Bosnia and Herzegovina, with two out of three largest banks in the country having their headquarters in Mostar. Bosnia-Herzegovina has three national electric, postal and telecommunication service corporations; These three companies banks and the aluminium factory make a vast portion of overall economic activity in the city.

Mostar area alone receives an income of €40 million annually from Aluminij. Prijedor Prijedor is the sixth largest city in Bosnia and Herzegovina. It is an economically prosperous municipality hosting a wide range of industries, services and educational institutions. The city's geographical location close to major European capitals has made it an important industrial and commercial hub nationally. It has a developed financial sector, 11 international banks are represented, 5 microcredit organizations and a foundation for development. The city's huge economic potential is in the strategic geographical location being close to Zagreb, Belgrade, Budapest and Vienna. Giving it one of the best climates for economic expansion in Bosnia and Herzegovina. The agricultural land around the city, raw minerals in the municipality and growth of high educated population in the city proper gives it a unique combination of both being able to produce sophisticated industrial products, food and service branches. Companies Zenica host today the Bosnian part of ArcelorMittal Steel Company, former RMK Zenica, which employ about 3000 workers, steel company from Luxembourg with over 320,000 employees in more than 60 countries. It also has companies specialized in the chemical industry such as Ferrox a.d., producing iron oxides-pigments. BosnaMontaza AD., one of Bosnias most specialized steel manufacturers, manufacturing: steel construction, pipelines, reservoirs, technological equipment, cranes and energy plants. Other companies such as the Croatian food company Kraš has one of its biggest facilities in Bosnia and Herzegovina in Prijedor, producing confectionery products under the brand names MIRA and Kraš. Brand names such as "Prijedorčanka" is one of the leading producers of the alcoholic beverage Rakija in Bosnia and Herzegovina.

Lake Saničani, near Prijedor, is one of the biggest commercial fish-farming lakes in the southern Europe. Prijedor municipality takes up 8340.6 hectares (5845.0 private property and 2495.6 state property). Plowed fields and gardens take up 340.26 hectares, orchards 23.86 hectares and vineyards 5 hectares. All cultivated soil takes up 402.06 hectares. Service sector The service sector in Prijedor is growing rapidly and this reflects in the growth of hotels, stores, roads, educational facilities and shoppings centers that are being built in the city. Making it a growing commercial hub in Bosnia and Hercegovina. Banja Luka Although the city itself was not directly affected by the Bosnian War in the early 1990s, its economy was. For four years, Banja Luka fell behind the world in key areas such as technology, resulting in a rather stagnant economy. However, in recent years, the financial services sector has gained in importance in the city. In 2002, the trading began on the newly established Banja Luka Stock Exchange. The number of companies listed, the trading volume and the number of investors have increased significantly. A number of big companies such as Telekom Srpske, Rafinerija ulja Modriča, Banjalučka Pivara and Vitaminka are all listed on the exchange and are traded regularly. Investors, apart from those from Slovenia, Croatia and Serbia, now include a number of investment funds from the European Union, Norway, the United States, Japan and China. A number of financial services regulators, such as the Indirect Taxation Authority of Bosnia and Herzegovina, Republika Srpska Securities Commission and the RS Banking Agency are headquartered in Banja Luka. This, along with the fact that some of the major banks in Bosnia, the Deposit Insurance Agency and the Value-added tax (VAT) Authority are all based in the city, has helped Banja Luka establish itself as a major financial centre of the country. In 1981 Banja Luka's GDP per capita was 97% of the Yugoslav average. Energy The country has been a heavy user of energy compared with the EU, with artificially low prices providing a disincentive to make savings. Heavily reliant on lignite coal for power generation, in 2021 Bosnia and Herzegovina is one of very few countries still making plans to expand coal energy generation. Statistics Renewable power Wind and Solar The first wind farm was built in 2018. The 2030 plan envisages 1.5 GW of solar power and 0.5 GW of wind power capacity being built. Hydro power In 2021 the country had around 2076 MW of installed hydropower capacity larger than 10 MW, with 180 MW of small hydropower units. Fossil fuels Coal In 2021 electricity production came from five main lignite coal power plants generating up to 2065 MW. Tuzla Thermal Power Plant was supposed to close unit 4 in 2022 however the government has extended this lignite coal generators life. Kakanj Power Station was also supposed to have closed unit 5 in 2022 under the 2006 Energy Community Treaty. Under the 2030 plan a number of coal power stations will close or convert to biomass. Breza coal mine Gacko coal mine Kakanj coal mine Kamengrad coal mine Kongora coal mine Stanari coal mine Tušnica coal mine Ugljevik coal mine Zenica coal mine Tourism The tourism sector has been recovering and helping the economy altogether in the process, with popular winter skiing destinations as well as summer countryside tourism. Bosnia and Herzegovina has been a top performer in recent years in terms of tourism development; tourist arrivals have grown by an average of 24% annually from 1995 to 2000. The European region's solid growth in arrivals in 2007 was due in significant part to Southern and Mediterranean Europe's strong performance (+7%). In particular, Bosnia and Herzegovina were among the stronger players with a growth of 20%. In 2012, Bosnia and Herzegovina had 747,827 tourists an increase of 9% and 1,645,521 overnight stays which is a 9,4% increase from 2012. 58.6% of the tourists came from foreign countries. According to an estimate of the World Tourism Organization, Bosnia and Herzegovina will have the third highest tourism growth rate in the world between 1995 and 2020. Of particular note is the diaspora population which often returns home during the summer months, bringing in an increase in retail sales and food service industry. In 2017, 1,307,319 tourists visited Bosnia and Herzegovina, an increase of 13.7%, and had 2,677,125 overnight hotel stays, a 12.3% increase from the previous year. Also, 71.5% of the tourists came from foreign countries. Challenges of doing business While business regulations are of comparable strictness as in most countries in Central Europe, many problems persist. Post-war high percentage of unemployment (16.85%) remains high, and the economical progress is very slow. Complicated bureaucracy system, complex procedures and often misconducted audition and regulation by public officers also make for volatile and insecure business environment, which is considered major hindrance to foreign investment into the country's industrial and manufacturing potential. The workforce is comparably cheap, with average net salary being €580, and average gross salary being €891, () and good skilled, especially in sectors present in pre-war economy. However, with slow but persistent know-how obsolescence, workforce exodus, high unemployment and long average time outside labor market for the unemployed, need a foreign-owned business investing in industry sectors where the country could be competitive. Bosnia and Herzegovina is also lacking a good e-governance structure, as well as good methods to enforce administrative accountability, both of which are considered necessary for more conductive business climate. Today it takes between 3–5 weeks to register a company in the country (and in some business sectors it can still take months to acquire all required permits, mostly due to administrative inefficiency), and many other business related administrative procedures are similarly convoluted and time-consuming. Political corruption is one of the more acute problems in Bosnia and Herzegovina, and along with size of administration and its inefficiency, the biggest detriment to tax money being spent where it should be spent – on services to the population and the economy. Bosnia and Herzegovina has been preparing for an era of declining international assistance. Country's most immediate task remains economic revitalization to create jobs and income. After the 2014 riots, both administrations have shyly started the reform, dealing with some of the many pressing issues to local economy, but the overall process is still considered slow and tenuous by the populace and local as well as foreign economic analysts. Infrastructure The Bosnian government has issued an international tender for the construction of the 350 km long Pan-European Corridor Vc in Bosnia and Herzegovina which will passes along the route Budapest-Osijek-Sarajevo-Ploče. The highway along this corridor is the most significant roadway in Bosnia and Herzegovina and the shortest communication route between Central Europe and the Southern Adriatic. The routing of the road passes through the central part of the country in the north–south direction from Donji Svilaj to the border of B&H, north from the Croatian port of Ploče, following the rivers Bosna and Neretva. More than 50% of the total population and the economic activity of Bosnia and Herzegovina lies within the zone of influence along this route. As of August 2018, 200 km motorway has been completed. Due to annual growth of nearly 10% the Sarajevo International Airport extension of the passenger terminal, together with upgrading and expanding the taxiway and apron is planned to start in Fall 2012. The existing terminal will be expanded with 7.000 square metres. The upgraded airport will also be directly connected to the commercial retail center Sarajevo Airport Center making it easy for tourist and travellers to use the time before the flight for some last minute shopping.

Economy of Botswana

The economy of Botswana is currently one of the world's fastest growing economies, averaging about 5% per annum over the past decade. Growth in private sector employment averaged about 10% per annum during the first 30 years of the country's independence. After a period of stagnation at the turn of the 21st century, Botswana's economy registered strong levels of growth, with GDP growth exceeding 6-7% targets. Botswana has been praised by the African Development Bank for sustaining one of the world's longest economic booms. Economic growth since the late 1960s has been on par with some of Asia's largest economies. The government has consistently maintained budget surpluses and has extensive foreign-exchange reserves. Botswana's impressive economic record compared to some of its neighbors has been built on a foundation of diamond mining, prudent fiscal policies, and a cautious foreign policy. Botswana's economy is mostly dependent on diamond mining. Diamond mining contributes to 50% of the government revenue mainly through its 50:50 joint venture with De Beers in the Debswana Diamond Company. It is rated as the least corrupt country in Africa in the Corruption Perceptions Index by international corruption watchdog Transparency International. It has the fourth highest gross national income per capita in purchasing power in Africa and above the world average. Trade unions represent a minority of workers in the Botswana economy. In general they are loosely organised "in-house" unions, although the Botswana Federation of Trade Unions (BFTU) is consolidating its role as the sole national trade union centre in the country. Although Botswana's economy is considered a model for countries in the region, its heavy dependence on mining and its high rate of HIV/AIDS infection (one in every three adults is seropositive) and unemployment could threaten its success in the future. History Agriculture still provides a livelihood for 70% of the rural population but supplies only about 50% of food needs and accounted for only 1.8% of GDP as of 2016. Subsistence farming and cattle raising predominate. The sector is plagued by erratic rainfall and poor soils. Diamond mining and tourism are also important to the economy. Substantial mineral deposits were found in the 1970s and the mining sector grew from 25% of GDP in 1980 to 38% in 1998. Unemployment officially stood at 21% as of 2000 but unofficial estimates placed it closer to 40%. Economic growth slowed in 2005-2008 and turned negative in 2009 as a result of the Great Recession, contracting by 5.2%. This was exacerbated by a major global downturn in the industrial sector, which shrank by 30%, Botswana's steep economic downturn contrasted with most other African nations which experienced continued growth through this period. Some of Botswana's budget deficits can be traced to relatively high military expenditures (about 4% of GDP in 2004, according to the CIA World Factbook). Some critics have criticized this level of military spending, given the low likelihood of international conflict, but these troops are also used for multilateral operations and assistance efforts. Trade Botswana is part of the Southern African Customs Union (SACU) with South Africa, Lesotho, Eswatini, and Namibia. The World Bank reports that in 2001 (the most recent year for which World Bank data is available), the SACU had a weighted average common external tariff rate of 3.6%. According to the U.S. Department of Commerce, "there are very few tariff or non-tariff barriers to trade with Botswana, apart from restrictions on licensing for some business operations, which are reserved for [Botswana] companies." Based on the revised trade factor methodology, Botswana's trade policy score is unchanged. The main export of Botswana is diamonds. As of 2017 it is the world's second largest producer of diamonds after Russia. Due to Botswana's heavy reliance on diamonds, strong global demand is vital to the health of the economy. Diamond exports provide Botswana's economy with strong supplies of foreign exchange and have offered a basis for industrial development and stimulated improvements in Botswana's infrastructure. However, despite their preeminent role in Botswana's economy, there are concerns that diamond mines are not labour-intensive enough to provide sufficient employment for Botswana's workforce, and this mismatch has been cited as a factor in the country's structurally high unemployment rate. Mining Two large mining companies, Debswana (formed by the government and South Africa's De Beers in equal partnership) and Bamangwato Concessions, Ltd. (BCL, also with substantial government equity participation) operate in the country. BCL was placed in provisional liquidation in late 2016, following years of loss-making operations, and was placed into final liquidation by the High Court in June 2017. Since early 1980s, the country has been one of the world's largest producers of gem diamonds. Four large diamond mines have opened since independence. De Beers prospectors discovered diamonds in northern Botswana in the early 1970s. The first mine began production at Orapa in 1972, followed by a smaller mine at Letlhakane. What has become the single richest diamond mine in the world opened in Jwaneng in 1982. The mine was discovered when termites looking for water brought grains of diamond to the surface. Botswana produced a total of 21.3 million carats of diamonds from the three Debswana mines in 1999, and is the highest producer of diamonds by value in the world. The Orapa 2000 Expansion of the existing Orapa mine was opened in 2000. According to Debswana, the Orapa 2000 Expansion project increase the Orapa's mine annual output from 6 million carats to 12 million carats and raised total production to 26 million carats. In 2003, Debswana opened the Damtshaa diamond mine about 220 kilometers (140 mi) west of the city of Francistown. The mine was placed into care and maintenance in December 2015 due to weak global demand but was scheduled to reopen in January 2018. In 2008, Australia's Kimberley Diamond Company opened a mine in Lerala, Botswana's fifth mine and the first not operated by Debswana. However, Kimberley shut down the mine in May 2017, citing weak market conditions. Most (70%) of Botswana's electricity is imported from South Africa's Eskom. 80% of domestic production is concentrated in one plant, Morupule Power Station near Palapye, operated by the Botswana Power Corporation. Debswana operates the nearby Morupule Colliery to supply coal to it. The Morupule mine exports coal to Zimbabwe, Zambia and the Democratic Republic of the Congo. In early 2008, the entire southern African region was hit hard by massive shortages of power, since the region works to share its power resources through the Southern African Power Pool, with most of its capacity coming from South Africa. Botswana has in turn put in place plans to become a net exporter of power to the regional pool, through governmental expansion of the Morupule power station, as well as encouraging private investment in the form of a 4 gigawatt power station by the Canadian greenfield company CIC Energy. In 2012, CIC Energy was acquired by India's Jindal Steel and Power. Jindal Africa currently aims to operate three surface mines in the coalfields of Mmamabula, as well as a power plant. According to the company, "the mine’s development will meet the demands of 600MW power stations and export region coal markets, with the potential to employ more than 2,000 people." Botswana also produces soda ash through Botash, a joint venture between the government and South Africa's Chlor-Alkali Holdings (CAH) Group. Botash has been operating in the Sua Pan in northeastern Botswana since April 1991. Production of soda ash is estimated at around 300,000 tonnes per annum and is exported to South Africa, Zambia, Zimbabwe, Malawi and the Democratic Republic of the Congo. Tourism Tourism is an increasingly important industry in Botswana, accounting for almost 12% of GDP. One of the world's unique ecosystems, the Okavango Delta, is located in Botswana. The country offers excellent game viewing and birding both in the Delta and in the Chobe National Park—home to one of the largest herds of free-ranging elephants in the world. Botswana's Central Kalahari Game Reserve also offers good game viewing and some of the remotest and most unspoiled wilderness in southern Africa. A number of national parks and game reserves, with their abundant wildlife and wetlands, are major tourist attractions. The main safari destinations for tourism are Moremi Game Reserve in the Okavango Delta, and Chobe National Park. Botswana is also participating in community-based natural resource management projects by trying to involve villagers in tourism. One example is the village of Khwai and its Khwai Development Trust. Botswana was the setting for the 1980 movie The Gods Must Be Crazy, although the movie was mostly filmed in South Africa. The seventh season of The Amazing Race visited Botswana. Tourism has been stimulated by the series of detective novels by Alexander McCall Smith and the American dramatisation that followed them. Agriculture More than half of Botswana's population lives in rural areas and depends on subsistence crops and livestock farming. Agriculture meets only a small portion of food needs and contributes just 2.6% to GDP as of 2002—primarily through beef exports—but it remains a social and cultural touchstone. Cattle raising dominated Botswana's social and economic life before independence. The Botswana Meat Commission (BMC) has a monopoly on beef production. The national herd was about 2.5 million in the mid-1990s, though the government-ordered slaughter of the entire herd in Botswana's north-west Ngamiland District in 1995 has reduced the number by at least 200,000. The slaughter was ordered to prevent the spread of "cattle lung disease" to other parts of the country. Unfortunately, their currency is Pula so money is hard to come by. Botswana produced, in 2018: 102 thousand tons of root and tubers; 46 thousand tons of vegetables; 17 thousand tons of sorghum; 13 thousand tons of maize; 8 thousand tons of cabbage; 6 thousand tons of onion; 5 thousand tons of tomato; In addition to smaller productions of other agricultural products. Manufacturing Manufacturing industries in Botswana include food processing, predominantly beef processing, diamond processing, textile and garment manufacturing, beverage making, jewellery making, metals and metal products, soap making, construction materials manufacturing, and glass production. Science and technology There is a growing science sector in Botswana. The number of publications by Botswanan scientists catalogued in international databases increased from 133 in 2009 to 210 in 2014. In 2018, Botswana produced 281 scientific and technical journal articles. The country has one of the highest levels of scientific productivity in Sub-Saharan Africa. The country also has a high-tech industry, being home to a number of information technology companies. In 2020, Botswana's high-tech exports were worth about $16.2 million. Private sector development and foreign investment Botswana seeks to diversify its economy away from minerals, the earnings from which have levelled off. In 1998–99, non-mineral sectors of the economy grew at 8.9%, partially offsetting a slight 4.4% decline in the minerals sector. Foreign investment and management have been welcomed in Botswana. External investment in Botswana has grown fitfully. In the early 1990s, two American companies, Owens Corning and H.J. Heinz, made major investments in production facilities in Botswana. In 1997, the St. Paul Group purchased Botswana Insurance, one of the country's leading short-term insurance providers. An American Business Council (ABC), with over 30 member companies, was inaugurated in 1995. Hyundai operated a car assembly plant in Botswana from 1994 to 2000. Botswana seeks to further diversify its economy away from minerals, which account for a quarter of GDP, down from nearly half of GDP in the early 1990s. Foreign investment and management are welcomed in Botswana and, as a result, the financial and services sectors have increased at an exponential rate in the 2000s to replace mining as the leading industry. Botswana abolished foreign exchange controls in 1999, has a low corporate tax rate (15%), no prohibitions on foreign ownership of companies, and as of 2001 had a moderate inflation rate (6.6%). The government considers private-sector participation as being critical to the success of the country's Tenth National Development Plan (2009–2016) and enhancing the role of research and development as being the most effective way to nurture entrepreneurship and private-sector growth. The government is considering additional policies to enhance competitiveness, including a new Foreign Direct Investment Strategy, Competition Policy, Privatisation Master Plan and National Export Development Strategy. Botswana is known to have vast coal deposits making it possibly one of the most coal-rich countries in the world. Large coal mines, massive coal-fired power plants, as well as a coals to liquid plant (through the Fischer–Tropsch process) to produce synthetic automotive fuel have been planned. With its proven record of good economic governance, Botswana was ranked as Africa's least corrupt country in the Corruption Perceptions Index in 2020, ahead of many European and Asian countries. The World Economic Forum rated Botswana as the third most economically competitive nation in Africa as of 2002. In 2001 Botswana was once again assigned "A" grade credit ratings by Moody's and Standard & Poor's. This ranks Botswana as by far the best credit risk in Africa and puts it on par with or above many countries in central Europe, East Asia, and Latin America. U.S. investment in Botswana remains at relatively low levels but continues to grow. Major U.S. corporations, such as Coca-Cola and H.J. Heinz, are present through direct investments, while others, such as Kentucky Fried Chicken, are present via franchise. The sovereign credit ratings by Moody's and Standard & Poor's clearly indicate that, despite continued challenges such as small market size, landlocked location, and cumbersome bureaucratic processes, Botswana remains one of the best investment opportunities in the developing world. Due to its history and geography, Botswana has long and deep ties to the economy of South Africa. The Southern Africa Customs Union (SACU), presently comprising Namibia, Botswana, Lesotho, Eswatini, and South Africa, dates from 1910. Under this arrangement, South Africa has collected levies from customs, sales, and excise duties for all five members, sharing out proceeds based on each country's portion of imports. The exact formula for sharing revenues and the decision-making authority over duties—held exclusively by the Government of South Africa—became increasingly controversial, and the members renegotiated the arrangement in 2001. The new structure has now been formally ratified and a SACU Secretariat has been established in Windhoek, Namibia. Following South Africa's accession to the World Trade Organization (WTO), Botswana also joined; many of the SACU duties are thus declining, making products from outside the area more competitive in Botswana. Currently, the SACU countries and the U.S. are negotiating a free trade agreement. Botswana is currently also negotiating a free trade agreement with Mercosur and an Economic Partnership Agreement with the European Union as part of SADC. Gaborone is host to the headquarters of the fourteen-nation Southern African Development Community (SADC), a successor to the Southern African Development Coordination Conference (SADCC, established in 1980), which focused its efforts on freeing regional economic development from dependence on apartheid South Africa. SADC embraced the newly democratic South Africa as a member in 1994 and has a broad mandate to encourage growth, development, and economic integration in Southern Africa. SADC's Trade Protocol, which was launched on 1 September 2000, calls for the elimination of all tariff and non-tariff barriers to trade by 2012 among the 11 signatory countries. If successful, it will give Botswana companies free access to the far larger regional market. SADC's failure to distance itself from the Mugabe government in Zimbabwe has diminished the number of opportunities for cooperation between the U.S. and SADC. Botswana has successfully carried an Action Programme on the Elimination of Child Labour, which was adopted in the period 2006–2007. Free the Children delisted Botswana as a nation harbouring child-labour facilities in 2008. Financial sector Botswana has a growing financial sector, and the country's national stock market, the Botswana Stock Exchange (BSE), based in Gaborone, is given the responsibility to operate and regulate the equities and fixed interest securities market. Formally established in 1989, the BSE continues to be pivotal to Botswana's financial system, and in particular the capital market, as an avenue on which government, quasi-government and the private sector can raise debt and equity capital. Although the BSE has just under 40 companies listed, it plays host to the most pre-eminent companies doing business in Botswana. These companies represent a spectrum of industries and commerce, from Banking and financial services to Wholesaling and Retailing, Tourism and Information Technology. To date, the BSE is one of Africa's best performing stock exchanges, averaging 24% aggregate return in the past decade. This has allowed the BSE to be the third largest stock exchange, in terms of market capitalisation, in Southern Africa. Given Botswana's lack of exchange controls, stable currency and exceptionally performing stock market, the financial sector has attracted a host of global investors seeking better returns. Botswana's currency, the pula, is fully convertible and is valued against a basket of currencies heavily weighted toward the South African Rand. Profits and direct investment can be repatriated without restriction from Botswana. The Botswana Government eliminated all exchange controls in 1999. The Central Bank devalued the Pula by 7.5% in February 2004 in a bid to maintain export competitiveness against the real appreciation of the Pula. There was a further 12% devaluation in May 2005 and the policy of a "Crawling peg" was adopted. The recently established Non-Bank Financial Institutions Regulatory Authority (NBFIRA) is responsible for the oversight of all non-banking financial services entities in the country. As of 2005, about 54% of Botswana's population had access to formal or informal financial services, and 43% is banked (with access to at least one formal banking product). The overall access ratio is still low, especially in rural areas, where there are 3.8 branches and 73 ATMs per 100,000 people. Mobile banking services have just started to be offered. In recent years the government and Central Bank have undertaken serious steps to modernize the country's payment system infrastructure. These efforts included the establishment of a code-line clearing system for the exchange of cheques and electronic funds as well as a Real Time Gross Settlement (RTGS) system, including SWIFT connection. The stock exchange implemented a Central Securities Depository in 2007. Remittance Flows for Botswana amounted to US$117 million in 2007, a figure that is higher than the total net value of official development assistance. Gaborone is host to the headquarters of the 14-nation Southern African Development Community (SADC). A successor to the Southern African Development Coordination Conference (SADCC), which focused its efforts on freeing regional economic development from dependence on apartheid in South Africa, SADC embraced the newly democratic South Africa as a member in 1994 and has a broad mandate to encourage growth, development, and economic integration in Southern Africa. SADC's Trade Protocol, which was launched on 1 September 2000, calls for the elimination of all tariff and non-tariff barriers to trade by 2012 among the 11 signatory countries. If successful, it will give Botswana companies free access to the far larger regional market. The Regional Centre for Southern Africa (RCSA), which implements the U.S. Agency for International Development's (USAID) Initiative for Southern Africa (ISA), is headquartered in Gaborone as well.

Economy of Brazil

The economy of Brazil is historically the largest in Latin America and the Southern Hemisphere in nominal terms. The Brazilian economy is the second largest in the Americas. The economy is a middle income developing mixed economy. In 2023, according to International Monetary Fund (IMF), Brazil has the 9th largest gross domestic product (GDP) in the world and has the 8th largest purchasing power parity in the world. In 2022, according to International Monetary Fund (IMF), Brazilian nominal GDP was US$1.894 trillion, the country has a long history of being among the ten largest economies in the world. The GDP per capita was US$8,857 per inhabitant. The country is rich in natural resources. From 2000 to 2012, Brazil was one of the fastest-growing major economies in the world, with an average annual GDP growth rate of over 5%. Its GDP surpassed that of the United Kingdom in 2012, temporarily making Brazil the world's sixth-largest economy. However, Brazil's economic growth decelerated in 2013 and the country entered a recession in 2014. The economy started to recover in 2017, with a 1% growth in the first quarter, followed by a 0.3% growth in second quarter compared to the same period of the previous year. It officially exited the recession. According to the World Economic Forum, Brazil was the top country in upward evolution of competitiveness in 2009, gaining eight positions among other countries, overcoming Russia for the first time, and partially closing the competitiveness gap with India and China among the BRICS economies. Important steps taken since the 1990s toward fiscal sustainability, as well as measures taken to liberalize and open the economy, have significantly boosted the country's competitiveness fundamentals, providing a better environment for private-sector development. In 2020, Forbes ranked Brazil as having the 7th largest number of billionaires in the world. Brazil is a member of diverse economic organizations, such as Mercosur, Prosur, G8+5, G20, WTO, Paris Club, Cairns Group, and is advanced to be a permanent member of the OECD. From a colony focused on primary sector goods (sugar, gold and cotton), Brazil managed to create a diversified industrial base during the 20th century. The steel industry is a prime example of that, with Brazil being the 9th largest steel producer in 2018, and the 5th largest steel net exporter in 2018. Gerdau is the largest producer of long steel in the Americas, and Vale is the largest producer of iron ore in the world. Petrobras, the Brazilian oil and gas company, is the most valuable company in Latin America. History When the Portuguese explorers arrived in the 16th century, the native tribes of current-day Brazil totaled about 2.5 million people and had lived virtually unchanged since the Stone Age. From Portugal's colonization of Brazil (1500–1822) until the late 1930s, the Brazilian economy relied on the production of primary products for exports. In the Portuguese Empire, Brazil was a colony subjected to an imperial mercantile policy, which had three main large-scale economic production cycles – sugar, gold and from the early 19th century on, coffee. The economy of Brazil was heavily dependent on African slave labor until the late 19th century (about 3 million imported African slaves in total). In that period Brazil was also the colony with the largest number of European settlers, most of them Portuguese (including Azoreans and Madeirans) but also some Dutch (see Dutch Brazil), Spaniards, English, French, Germans, Flemish, Danish, Scottish and Sephardic Jews. Subsequently, Brazil experienced a period of strong economic and demographic growth accompanied by mass immigration from Europe, mainly from Portugal (including the Azores and Madeira), Italy, Spain, Germany, Poland, Ukraine, Switzerland, Austria and Russia. Smaller numbers of immigrants also came from the Netherlands, France, Finland, Iceland and the Scandinavian countries, Lithuania, Belgium, Bulgaria, Hungary, Greece, Latvia, England, Ireland, Scotland, Croatia, Czech Republic, Malta, North Macedonia and Luxembourg, the Middle East (mainly from Lebanon, Syria and Armenia), Japan, the United States and South Africa, until the 1930s.In fact, international mass immigration to Brazil during the 19th century had positive effects on the country's human capital development. Immigrants usually exhibited better formal and informal training than native Brazilians and tended to have more entrepreneurial spirit. Their arrival was beneficial for the region, not only because of the skills and knowledge they brought to the country themselves, but also because of spillover effects of their human capital to the native Brazilian population. Human capital spillover effects were strongest in regions with the highest numbers of immigrants, and the positive effects are still observable today, in some regions. In 2007, with a population of over 190 million and abundant natural resources, Brazil is one of the ten largest markets in the world, producing tens of millions of tons of steel, 26 million tons of cement, 3.5 million television sets, and 3 million refrigerators. In addition, about 70  million cubic meters of petroleum were being processed annually into fuels, lubricants, propane gas, and a wide range of hundreds of petrochemicals. Brazil has at least 161,500 kilometers of paved roads, more than 150 gigawatts of installed electric power capacity and its real per capita GDP surpassed US$9,800 in 2017. Its industrial sector accounts for three-fifths of the South American economy's industrial production. The country's scientific and technological development is argued to be attractive to foreign direct investment, in 2019, Brazil occupied the 4th largest destination for foreign investments, behind only the United States, China and Singapore. The agricultural sector, locally called the agronegócio (agro-business), has also been dynamic: for two decades this sector has kept Brazil among the most highly productive countries in areas related to the rural sector. The agricultural sector and the mining sector also supported trade surpluses which allowed for massive currency gains (rebound) and external debt paydown. Due to a downturn in Western economies, Brazil found itself in 2010 trying to halt the appreciation of the real. Data from the Asian Development Bank and the Tax Justice Network show the untaxed "shadow" economy of Brazil is 39% of GDP. One of the most important corruption cases in Brazil concerns the company Odebrecht. Since the 1980s, Odebrecht has spent several billion dollars in the form of bribes to bribe parliamentarians to vote in favour of the group. At the municipal level, Odebrecht's corruption was aimed at "stimulating privatisations", particularly in water and sewer management. Data The following table shows the main economic indicators in 1980–2021 (with FMI estimates for 2022–2027). Inflation below 5% is in green. Components The service sector is the largest component of the gross domestic product (GDP) at 67.0 percent, followed by the industrial sector at 27.5 percent. Agriculture represents 5.5 percent of GDP (2011). The Brazilian labor force is estimated at 100.77 million of which 10 percent is occupied in agriculture, 19 percent in the industry sector and 71 percent in the service sector. Agricultural Sector Brazil is the world's largest producer of sugarcane, soy, coffee, orange, guaraná, açaí and Brazil nut; is one of the top 5 producers of maize, papaya, tobacco, pineapple, banana, cotton, beans, coconut, watermelon and lemon; is one of the top 10 world producers of cocoa, cashew, avocado, tangerine, persimmon, mango, guava, rice, sorghum and tomato; and is one of the top 15 world producers of grape, apple, melon, peanut, fig, peach, onion, palm oil and natural rubber. In the production of animal proteins, Brazil is today one of the largest countries in the world. In 2019, the country was the world's largest exporter of chicken meat. It was also the second largest producer of beef, the world's third largest producer of milk, the world's fourth largest producer of pork and the seventh largest producer of eggs in the world. Agribusiness contributes to Brazil's trade balance, in spite of trade barriers and subsidizing policies adopted by the developed countries. In the space of fifty five years (1950 to 2005), the population of Brazil grew from 51 million to approximately 187 million inhabitants, an increase of over 2 percent per year. Brazil created and expanded a complex agribusiness sector. However, some of this is at the expense of the environment, including the Amazon. The importance given to the rural producer takes place in the shape of the agricultural and cattle-raising plan and through another specific subsidy program geared towards family agriculture Programa de Fortalecimento da Agricultura Familiar (Pronaf), which guarantees financing for equipment and cultivation and encourages the use of new technology. With regards to family agriculture, over 800 thousand rural inhabitants are assisted by credit, research and extension programs. A special line of credit is available for women and young farmers. With The Land Reform Program, on the other hand, the country's objective is to provide suitable living and working conditions for families who live in areas allotted by the State, an initiative capable of generating jobs. Through partnerships, public policies and international partnerships, the government is working towards guaranteeing infrastructure for the settlements, following the examples of schools and health outlets. The idea is that access to land represents just the first step towards the implementation of a quality land reform program. Over 600,000 km2 of land are divided into approximately five thousand areas of rural property; an agricultural area currently with three borders: the Central-western region (savannah), the northern region (area of transition) and parts of the northeastern region (semi-arid). At the forefront of grain crops, which produce over 110 million tonnes/year, is the soybean, yielding 50 million tonnes. In the cattle-raising sector, the "green ox," which is raised in pastures, on a diet of hay and mineral salts, conquered markets in Asia, Europe and the Americas, particularly after the "mad cow disease" scare period. Brazil has the largest cattle herd in the world, with 198 million heads, responsible for exports of more than US$1 billion/year. A pioneer and leader in the manufacture of short-fiber timber cellulose, Brazil has also achieved positive results within the packaging sector, in which it is the fifth largest world producer. In the foreign markets, it answers for 25 percent of global exports of raw cane and refined sugar; it is the world leader in soybean exports and is responsible for 80 percent of the planet's orange juice, and since 2003, has had the highest sales figures for beef and chicken. Mining In the mining sector, Brazil stands out in the extraction of iron ore (where it is the second world exporter), copper, gold, bauxite (one of the 5 largest producers in the world), manganese (one of the 5 largest producers in the world), tin (one of the largest producers in the world), niobium (concentrates 98% of reserves known to the world) and nickel. In terms of gemstones, Brazil is the world's largest producer of amethyst, topaz, agate and one of the main producers of tourmaline, emerald, aquamarine, garnet and opal. In 2019, Brazil's figures were as follows: it was the world's largest producer of niobium (88.9 thousand tons); the 2nd largest world producer of tantalum (430 tons); the 2nd largest world producer of iron ore (405 million tons); the 4th largest world producer of manganese (1.74 million tons); the 4th largest world producer of bauxite (34 million tons); the 4th largest world producer of vanadium (5.94 thousand tons); the 5th largest world producer of lithium (2.4 thousand tons); the 6th largest world producer of tin (14 thousand tons); the 8th largest world producer of nickel (60.6 thousand tons); the 8th largest world producer of phosphate (4.7 million tons); the 12th largest world producer of gold (90 tons); the 14th largest world producer of copper (360 thousand tons); the 14th largest world producer of titanium (25 thousand tons); the 13th largest world producer of gypsum (3 million tons); the 3rd largest world producer of graphite (96 thousand tons); the 21st largest world producer of sulfur (500 thousand tons); the 9th largest world producer of salt (7.4 million tons); besides having had a chromium production of 200 thousand tons. Industry Brazil has the second-largest manufacturing sector in the Americas. Accounting for 28.5 percent of GDP, Brazil's industries range from automobiles, steel and petrochemicals to computers, aircraft, and consumer durables. With increased economic stability provided by the Plano Real, Brazilian and multinational businesses have invested heavily in new equipment and technology, a large proportion of which has been purchased from U.S. firms. The World Bank lists the main producing countries each year, based on the total production value. According to the 2019 list, Brazil has the 13th most valuable industry in the world (US$173.6 billion). In the Americas, it is second only to the United States (2nd place) and Mexico (12th place). In the food industry, in 2019, Brazil was the second largest exporter of processed foods in the world. In 2016, the country was the 2nd largest producer of pulp in the world and the 8th producer of paper. In the footwear industry, in 2019, Brazil ranked 4th among world producers. In 2019, the country was the 8th producer of vehicles and the 9th producer of steel in the world. In 2018, the chemical industry of Brazil was the 8th in the world. In textile industry, Brazil, although it was among the 5 largest world producers in 2013, is very little integrated in world trade. In the aviation sector, Brazil has Embraer, the third largest aircraft manufacturer in the world, behind Boeing and Airbus. Brazil has a diverse and sophisticated services industry as well. During the early 1990s, the banking sector accounted for as much as 16 percent of the GDP. Although undergoing a major overhaul, Brazil's financial services industry provides local businesses with a wide range of products and is attracting numerous new entrants, including U.S. financial firms. On 8 May 2008, the São Paulo Stock Exchange (Bovespa) and the São Paulo-based Brazilian Mercantile and Futures Exchange (BM&F) merged, creating BM&F Bovespa, one of the largest stock exchanges in the world. Also, the previously monopolistic reinsurance sector is being opened up to third-party companies. 31 December 2007, there were an estimated 21,304,000 broadband lines in Brazil. Over 75 percent of the broadband lines were via DSL and 10 percent via cable modems. Proven mineral resources are extensive. Large iron and manganese reserves are important sources of industrial raw materials and export earnings. Deposits of nickel, tin, chromite, uranium, bauxite, beryllium, copper, lead, tungsten, zinc, gold, and other minerals are exploited. High-quality coking-grade coal required in the steel industry is in short supply. Creative Industries The first study into the impact of the Creative Industries on the Brazilian economy was published by FIRJAN. The creative economy in Latin America was termed the "Orange Economy" in a publication released by the Inter-American Development Bank (IDB). This 2013 study valued Brazil's Orange Economy at US$66.87 billion providing 5,280,000 jobs and responsible for US$9.414 million in exports, with the value of creative exports being higher than the US$8.016 million value of coffee exports over the same period. A 2021 study into the Intellectual Property Intensive Sectors in the Brazilian Economy was undertaken as part of the National Strategy on Intellectual Property 2021–2030. The study found that 450 of the 673 economic classes could be classified as IP-intensive sectors that collectively employed 19.3 million people. The share of GDP between 2014 and 2016 across these economic classes amounted to R$2.1 trillion reais or 44.2% of GDP over this time. Tourism In the list of world tourist destinations, in 2018, Brazil was the 48th most visited country, with 6.6 million tourists (and revenues of 5.9 billion dollars). Tourism in South America as a whole is still underdeveloped: in Europe, for example, countries obtain annual tourism figures like $73.7 billion (Spain), receiving 82.7 million tourists or 67.3 billion (France), receiving 89.4 million tourists. While Europe received 710 million tourists in 2018, Asia 347 million and North America 142.2 million, South America received only 37 million, Central America 10.8 million and the Caribbean 25.7 million. Largest companies In 2017, 20 Brazilian companies were listed in the Forbes Global 2000 list – an annual ranking of the top 2000 public companies in the world by Forbes magazine based on a combination of sales, assets, profit, and market value. The 20 companies listed were: Energy The Brazilian government has undertaken an ambitious program to reduce dependence on imported petroleum. Imports previously accounted for more than 70% of the country's oil needs but Brazil became self-sufficient in oil in 2006–2007. Brazil was the 10th largest oil producer in the world in 2019, with 2.8 million barrels / day. Production manages to supply the country's demand. In the beginning of 2020, in the production of oil and natural gas, the country exceeded 4 million barrels of oil equivalent per day, for the first time. In January this year, 3.168 million barrels of oil per day and 138.753 million cubic meters of natural gas were extracted. Brazil is one of the main world producers of hydroelectric power. In 2019, Brazil had 217 hydroelectric plants in operation, with an installed capacity of 98,581 MW, 60.16% of the country's energy generation. In the total generation of electricity, in 2019 Brazil reached 170,000 megawatts of installed capacity, more than 75% from renewable sources (the majority, hydroelectric). In 2013, the Southeast Region used about 50% of the load of the National Integrated System (SIN), being the main energy consuming region in the country. The region's installed electricity generation capacity totaled almost 42,500 MW, which represented about a third of Brazil's generation capacity. The hydroelectric generation represented 58% of the region's installed capacity, with the remaining 42% corresponding basically to the thermoelectric generation. São Paulo accounted for 40% of this capacity; Minas Gerais by about 25%; Rio de Janeiro by 13.3%; and Espírito Santo accounted for the rest. The South Region owns the Itaipu Dam, which was the largest hydroelectric plant in the world for several years, until the inauguration of Three Gorges Dam in China. It remains the second largest operating hydroelectric in the world. Brazil is the co-owner of the Itaipu Plant with Paraguay: the dam is located on the Paraná River, located on the border between countries. It has an installed generation capacity of 14 GW for 20 generating units of 700 MW each. North Region has large hydroelectric plants, such as Belo Monte Dam and Tucuruí Dam, which produce much of the national energy. Brazil's hydroelectric potential has not yet been fully exploited, so the country still has the capacity to build several renewable energy plants in its territory. according to ONS, total installed capacity of wind power was 22 GW, with average capacity factor of 58%. While the world average wind production capacity factors is 24.7%, there are areas in Northern Brazil, specially in Bahia State, where some wind farms record with average capacity factors over 60%; the average capacity factor in the Northeast Region is 45% in the coast and 49% in the interior. In 2019, wind energy represented 9% of the energy generated in the country. In 2019, it was estimated that the country had an estimated wind power generation potential of around 522 GW (this, only onshore), enough energy to meet three times the country's current demand. In 2021 Brazil was the 7th country in the world in terms of installed wind power (21 GW), and the 4th largest producer of wind energy in the world (72 TWh), behind only China, USA and Germany. Nuclear energy accounts for about 4% of Brazil's electricity. The nuclear power generation monopoly is owned by Eletronuclear (Eletrobrás Eletronuclear S/A), a wholly owned subsidiary of Eletrobrás. Nuclear energy is produced by two reactors at Angra. It is located at the Central Nuclear Almirante Álvaro Alberto (CNAAA) on the Praia de Itaorna in Angra dos Reis, Rio de Janeiro. It consists of two pressurized water reactors, Angra I, with capacity of 657 MW, connected to the power grid in 1982, and Angra II, with capacity of 1,350 MW, connected in 2000. A third reactor, Angra III, with a projected output of 1,350 MW, is planned to be finished. according to ONS, total installed capacity of photovoltaic solar was 21 GW, with average capacity factor of 23%. Some of the most irradiated Brazilian States are MG ("Minas Gerais"), BA ("Bahia") and GO (Goiás), which have indeed world irradiation level records. In 2019, solar power represented 1,27% of the energy generated in the country. In 2021, Brazil was the 14th country in the world in terms of installed solar power (13 GW), and the 11th largest producer of solar energy in the world (16.8 TWh). In 2020, Brazil was also the 2nd largest country in the world in the production of energy through biomass (energy production from solid biofuels and renewable waste), with 15,2 GW installed. Transport Transport in Brazil is basically carried out using the road mode, the most developed in the region. There is also a considerable infrastructure of ports and airports. The railway and fluvial sector, although it has potential, is usually treated in a secondary way. Brazil has more than 1.7 million km of roads, of which 215,000 km are paved, and about 14,000 km are divided highways. The two most important highways in the country are BR-101 and BR-116. Due to the Andes Mountains, Amazon River and Amazon Forest, there have always been difficulties in implementing transcontinental or bioceanic highways. Practically the only route that existed was the one that connected Brazil to Buenos Aires, in Argentina and later to Santiago, in Chile. However, in recent years, with the combined effort of South American countries, new routes have started to emerge, such as Brazil-Peru (Interoceanic Highway), and a new highway between Brazil, Paraguay, northern Argentina and northern Chile (Bioceanic Corridor). There are more than 2,000 airports in Brazil. The country has the second largest number of airports in the world, behind only the United States. São Paulo International Airport, located in the Metropolitan Region of São Paulo, is the largest and busiest in the country – the airport connects São Paulo to practically all major cities around the world. Brazil has 44 international airports, such as those in Rio de Janeiro, Brasília, Belo Horizonte, Porto Alegre, Florianópolis, Cuiabá, Salvador, Recife, Fortaleza, Belém and Manaus, among others. The 10 busiest airports in South America in 2017 were: São Paulo-Guarulhos (Brazil), Bogotá (Colombia), São Paulo-Congonhas (Brazil), Santiago (Chile), Lima (Peru), Brasília (Brazil), Rio de Janeiro (Brazil), Buenos Aires-Aeroparque (Argentina), Buenos Aires-Ezeiza (Argentina), and Minas Gerais (Brazil). About ports, Brazil has some of the busiest ports in South America, such as Port of Santos, Port of Rio de Janeiro, Port of Paranaguá, Port of Itajaí, Port of Rio Grande, Port of São Francisco do Sul and Suape Port. The 15 busiest ports in South America are: Port of Santos (Brazil), Port of Bahia de Cartagena (Colombia), Callao (Peru), Guayaquil (Ecuador), Buenos Aires (Argentina), San Antonio (Chile), Buenaventura (Colombia), Itajaí (Brazil), Valparaíso (Chile), Montevideo (Uruguay), Paranaguá (Brazil), Rio Grande (Brazil), São Francisco do Sul (Brazil), Manaus (Brazil) and Coronel (Chile). The Brazilian railway network has an extension of about 30,000 kilometers. It's basically used for transporting ores. Among the main Brazilian waterways, two stand out: Hidrovia Tietê-Paraná (which has a length of 2,400 km, 1,600 on the Paraná River and 800 km on the Tietê River, draining agricultural production from the states of Mato Grosso, Mato Grosso do Sul, Goiás and part of Rondônia, Tocantins and Minas General) and Hidrovia do Solimões-Amazonas (it has two sections: Solimões, which extends from Tabatinga to Manaus, with approximately 1600 km, and Amazonas, which extends from Manaus to Belém, with 1650 km. Almost entirely passenger transport from the Amazon basin is done by this waterway, in addition to practically all cargo transportation that is directed to the major regional centers of Belém and Manaus). In Brazil, this transport is still underutilized: the most important waterway stretches, from an economic point of view, are found in the Southeast and South of the country. Its full use still depends on the construction of locks, major dredging works and, mainly, of ports that allow intermodal integration. Exports and imports Products Brazil was the 25th largest exporter in the world in 2020, with 1.1% of the global total. In 2021, Brazil exported US$280.4 billion and imported US$219.4 billion, with a surplus of US$61 billion. The country's top ten export products were: Iron ore: US$42.2 billion Soy: US$37.3 billion Crude petroleum oils: US$27.4 billion Sugar: US$8.5 billion Beef: US$7.4 billion Soybean meal: US$7.2 billion Petroleum fuel oils: US$6.6 billion Manufacturing Industry: US$6.4 billion Chicken meat: US$6.3 billion Cellulose: US$6.1 billion The country also exports maize, coffee, cotton, tobacco, orange juice, footwear, airplanes, helicopters, cars, vehicle parts, gold, ethanol, semi-finished iron, among others. Exports The main countries to which Brazil exports in 2021 were: China: US$87.6 billion (31.28%) United States: US$31.1 billion (11.09%) Argentina: US$11.8 billion (4.24%) Netherlands: US$9.3 billion (3.32%) Chile: US$6.9 billion (2.50%) Singapore: US$5.8 billion (2.10%) Mexico: US$5.5 billion (1.98%) Germany: US$5.5 billion (1.97%) Japan: US$5.5 billion (1.97%) Spain: US$5.4 billion (1.94%) The country's export model, until today, is excessively based on exports of basic or semi-manufactured products, generating criticism, since such model generates little monetary value, which prevents further growth in the country in the long run. There are several factors that cause this problem, the main ones being: the excessive collection of taxes on production (due to the country's economic and legislative model being based on State Capitalism and not on Free-Market Capitalism), the lack or deficiency of infrastructure (means of transport such as roads, railways and ports that are insufficient or weak for the country's needs, bad logistics and excessive bureaucracy) for export, high production costs (expensive energy, expensive fuel, expensive maintenance of trucks, expensive loan rates and bank financing for production, expensive export rates), the lack of an industrial policy, the lack of focus on adding value, the lack of aggressiveness in international negotiations, in addition to abusive tariff barriers imposed by other countries on the country's exports. Because of this, Brazil has never been very prominent in international trade. Due to its size and potential, it would be able to be among the 10 largest exporters in the world, however, its participation in global commercial transactions usually oscillates between 0.5 and 2% only. In 2019, among the ten products that Brazil exports the most and that generate the most value, eight come from the agribusiness. Although still modest, the country's exports have evolved, and today they are more diversified than they were in the past. At the beginning of the 20th century, 70% of Brazilian exports were restricted to coffee. Overall, however, global trade still concentrates its few exports on low-tech products (mainly agricultural and mineral commodities) and, therefore, with low added value. Imports The main countries from which Brazil imports in 2021 were: China: US$47.6 billion (21.72%) United States: US$39.3 billion (17.95%) Argentina: US$11.9 billion (5.45%) Germany: US$11.3 billion (5.17%) India: US$6.7 billion (3.07%) Russia: US$5.7 billion (2.60%) Italy: US$5.4 billion (2.50%) Japan: US$5.1 billion (2.35%) South Korea: US$5.1 billion (2.33%) France: US$4.8 billion (2.19%) Economic status Sustainable growth Portuguese explorers arrived in 1500, but it was only in 1808 that Brazil obtained a permit from the Portuguese colonial government to set up its first factories and manufacturers. In the 21st century, Brazil became the eighth largest economy in the world. Originally, its exports were basic raw and primary goods, such as sugar, rubber and gold. Today, 84% of exports are of manufactured and semi-manufactured products. The period of great economic transformation and growth occurred between 1875 and 1975. In the last decade, domestic production increased by 32.3%. Agribusiness (agriculture and cattle-raising), which grew by 47% or 3.6% per year, was the most dynamic sector – even after having weathered international crises that demanded constant adjustments to the Brazilian economy. The Brazilian government also launched a program for economic development acceleration called Programa de Aceleração do Crescimento, aiming to spur growth. Brazil's transparency rank in the international world is 75th according to Transparency International. Control and reform Among measures recently adopted to balance the economy, Brazil carried out reforms to its social security (state and retirement pensions) and tax systems. These changes brought with them a noteworthy addition: a Law of Fiscal Responsibility which controls public expenditure by the executive branches at federal, state and municipal levels. At the same time, investments were made towards administration efficiency and policies were created to encourage exports, industry and trade, thus creating "windows of opportunity" for local and international investors and producers. With these alterations in place, Brazil has reduced its vulnerability: it does not import the oil it consumes; it has halved its domestic debt through exchange rate-linked certificates and has seen exports grow, on average, by 20% a year. The exchange rate does not put pressure on the industrial sector or inflation (at 4% a year), and does away with the possibility of a liquidity crisis. As a result, the country, after 12 years, has achieved a positive balance in the accounts which measure exports/imports, plus interest payments, services and overseas payment. Thus, respected economists say that the country will not be deeply affected by the current world economic crisis. In 2017, President Michel Temer refused to make public the list of companies accused of "modern slavery". The list, made public yearly since the presidency of Lula Da Silva in 2003, was intended to persuade companies to settle their fines and conform to labor regulations, in a country where corruption of the political class risked compromising respect for the law. The relations of the president-in-office with the "landowner lobby" were denounced by dismissed President Dilma Rousseff on this occasion. Consistent policies Support for the productive sector has been simplified at all levels; active and independent, Congress and the Judiciary Branch carry out the evaluation of rules and regulations. Among the main measures taken to stimulate the economy are the reduction of up to 30 percent on manufactured products tax (IPI), and the investment of $8 billion on road cargo transportation fleets, thus improving distribution logistics. Further resources guarantee the propagation of business and information telecenters. The policy for industry, technology and foreign trade, at the forefront of this sector, for its part, invests $19.5 billion in specific sectors, following the example of the software and semiconductor, pharmaceutical and medicine product, and capital goods sectors. Mergers and acquisitions Between 1985 and 2017, 11,563 mergers & acquisitions with a total known value of US$1,185 billion with the involvement of Brazilian firms were announced. The year 2010 was a new record in terms of value with $115 billion of transactions. It is worth noticing, that in the top 100 deals by value there are only four cases of Brazilian companies acquiring a foreign company. This reflects the strong interest in the country from a direct investment perspective. Here is a list of the largest deals where Brazilian companies took on either the role of the acquiror or the target: Entrepreneurship According to a search of Global Entrepreneurship Monitor in 2011 Brazil had 27 million adults aged between 18 and 64 either starting or owning a business, meaning that more than one in four Brazilian adults were entrepreneurs. In comparison to the other 54 countries studied, Brazil was the third-highest in total number of entrepreneurs. The Institute of Applied Economic Research (Ipea), a government agency, found that 37 million jobs in Brazil were associated with businesses with less than 10 employees. Even though Brazil ranks internationally as one of the hardest countries in the region to do business due to its complicated bureaucracy, there is a healthy number of entrepreneurs, thanks to the huge internal consumer market and various government programs. The most recent research of Global Entrepreneurship Monitor revealed in 2013 that 50.4% of Brazilian new entrepreneurs are men, 33.8% are in the 35–44 age group, 36.9% completed high school and 47.9% earn 3–6 times the Brazilian minimum wage. In contrast, 49.6% of entrepreneurs are female, only 7% are in the 55–64 age group, 1% have postgraduate education and 1.7% earn more than 9 times the minimum wage. Credit rating Brazil's credit rating was downgraded by Standard & Poor's (S&P) to BBB in March 2014, just one notch above junk. It was further downgraded in January 2018 by S&P to BB-, which is 2 notches below investment grade.

Telecommunications in Brazil

Brazil has both modern technologies in the center-south portion, counting with LTE, 3G HSPA, DSL ISDB based Digital TV. Other areas of the country, particularly the North and Northeast regions, lack even basic analog PSTN telephone lines. This is a problem that the government is trying to solve by linking the liberation of new technologies such as WiMax and FTTH) only tied with compromises on extension of the service to less populated regions. Telephone system Landline The Brazilian landline sector is fully open to competition and continues to attract operators. The bulk of the market is divided between three operators: Telefónica, América Móvil, and Oi (controlled by Brazilian investors and Pharol SGPS). Telefónica operates through Telefónica Brasil, which has integrated its landline and mobile services under the brand name Vivo. The América Móvil group in Brazil comprises long distance incumbent Embratel, mobile operator Claro, and cable TV provider Net Serviços. The group has started to integrate its landline and mobile services under the brand name Claro, previously used only for mobile services. Oi offers landline and mobile services under the Oi brand name. GVT was the country's most successful alternative network provider, offering landline services only, until it was acquired by Telefónica in 2015 and integrated into Vivo. National: extensive microwave radio relay system and a national satellite system with 64 earth stations. International: country code - 55; landing point for a number of submarine cables, including Atlantis 2, that provide direct links to South and Central America, the Caribbean, the US, Africa, and Europe; satellite earth stations - 3 Intelsat (Atlantic Ocean), 1 Inmarsat (Atlantic Ocean region east), connected by microwave relay system to Mercosur Brazilsat B3 satellite earth station (2007) Statistics Served locations: 37,355 Installed terminals: 43,626,836 In service: 33,800,370 Public terminals: 1,128,350 Density: 22,798 Phones/100 Hab Mobile The history of mobile telephony in Brazil began on 30 December 1990, when the Cellular Mobile System began operating in the city of Rio de Janeiro, with a capacity for 10,000 terminals. At that time, according to Anatel (the national telecommunications agency), there were 667 devices in the country. The number of devices rose to 6,700 in the next year, to 30,000 in 1992. In November 2007 3G services were launched, and increased rapidly to almost 90% of the population in 2012 and the agreements signed as part of the auction specify a 3G coverage obligation of 100% of population by 2019. After the auction that took place in June 2012, LTE tests were undertaken in several cities, tourist locations and international conference venues. The first LTE-compatible devices became available in the local market and LTE services was commercially launched in 2013. Under the 4G licence terms, operators were required to have commercial networks in all twelve state capitals which are acting as host cities for the 2014 FIFA World Cup. 5G services were commercially launched in 2020, initially only in a few cities and in DSS mode. In 2021, the regulatory agency Anatel carried out the auction of the 3.5 GHz spectrum, which allowed the operation of 5G in standalone mode (SA). In July 2022, Brasília was the first city to have 5G NR SA made available, with all state capitals being served by the three major carriers by the end of 2022. By July 2023, 753 cities had 5G coverage, which accounts for 46% of the country's population. The mobile market is ruled by 3 companies: Vivo, controlled by the Spanish Telefónica, is the leading mobile and landline carrier in Brazil. In 1Q2023, Vivo served 98 million mobile subscribers. Claro, controlled by the Mexican América Móvil (owned by Carlos Slim), ranks second in Brazilian mobile market. In 1Q2023, Claro served 82.8 million mobile subscribers. TIM, controlled by the Italian Telecom Italia is the third largest mobile carrier in Brazil. In 1Q2023, TIM served 61.7 million mobile subscribers. Oi, which was once Brazil's fourth-largest mobile carrier, filed for judicial reorganization in 2016, selling its mobile division (Oi Móvel) in 2020 to a consortium formed by the three largest operators. In 2022, the sale was approved by the regulatory agency Anatel and Oi's 36.5 million mobile customers were transferred to TIM (40%), Claro (32%) and Vivo (28%). Algar Telecom is the largest regional mobile carrier, operating in 4 states. The company's customers have national coverage through roaming agreements with the three major telcos. In 1Q2023, Algar Telecom served 4.5 million mobile subscribers. Statistics Number of devices: 251.203.715 Percentage of prepaid lines: 43.62% Density: 98.7 phones/100 hab Technology distribution International backbones Submarine cables Several submarine cables link Brazil to the world: Americas II cable entered operations in September 2000, connecting Brazil (Fortaleza) to United States.

This is the only cable that connects South America to Africa and Europe. EMERGIA – SAM 1 cable connects all three Americas, surrounding it with a total extension of more than 25 thousand kilometers. GLOBAL CROSSING - SAC Connects all Americas, surrounding them with a total extension of more than 15 thousand kilometers. GLOBENET/360 NETWORK Another link from North America to South America. UNISUR Interconnects Brazil, Uruguay and Argentina. All these cables have a bandwidth from 20 Gbit/s to 80 Gbit/s, and some have a projected final capacity of more than 1 Tbit/s. Satellite connections List of business and satellites they operate (Brazilian Geostationary Satellites) Television and radio Under the Brazilian constitution, television and radio are not treated as forms of telecommunication, in order to avoid creating problems with a series of regulations that reduce and control how international businesses and individuals can participate. Brazil has the second largest media conglomerate in the world in terms of revenue, Grupo Globo. Internet The Internet has become quite popular in Brazil, with steadily growing numbers of users as well as increased availability. Brazil holds the 6th spot in number of users worldwide. Many technologies are used to bring broadband Internet to consumers, with DSL and cable being the most common (respectively, about 13 million and 9 million connections), and 3G technologies. 4G technologies were introduced in April 2013 and presently are available in over 90% of the country.

Transport in Brazil

Transport infrastructure in Brazil is characterized by strong regional differences and lack of development of the national rail network. Brazil's fast-growing economy, and especially the growth in exports, will place increasing demands on the transport networks. However, sizeable new investments that are expected to address some of the issues are either planned or in progress. It is common to travel domestically by air because the price is low. Brazil has the second highest number of airports in the world, after the USA. Railways The Brazilian railway network has an extension of about . It is basically used for transporting ores. Usually, the railway sector was treated in a secondary way in Brazil, due to logistical, economic or political difficulties to install more railways. The Brazilian railroad system had a great expansion between 1875 and 1920. The heyday of the railway modal was interrupted during the Getúlio Vargas government, which prioritized the road modal. In the 1940s, the railway network was already facing several problems, from low-powered locomotives to uneconomical layouts. In 1957, a state-owned company was created, the National Railroad Network (RFFSA), which started to manage 18 railroads in the Union. Several deficit railways were closed under the promise of state investment in new projects, which did not happen. The actions were centralized in the government until the opening of the market in 1990. So, the National Privatization Plan was instituted, with dozens of concessions being made. However, they ended up concentrating the railways, mainly, in three large business groups, América Latina Logística (ALL), Vale S.A. and MRS Logística. The refurbishment generated an increase in productivity (cargoes transported increased by 30% with the same railway line). However, the main problem was that the reform not only gave away the railway line, but also geographical exclusivity. This resulted in the non-creation of competitive incentives for the expansion and renewal of the existing network. With the State maintaining the opening of new railways a difficult, slow and bureaucratic process, as it maintains the total monopoly of power over this sector, the railways did not expand any further in the country, and the sector was very outdated. In 2021, a New Framework for Railways was created, allowing the construction of railways by authorization, as occurs in the exploration of infrastructure in sectors such as telecommunications, electricity and ports. It's also possible to authorize the exploration of stretches not implemented, idle, or in the process of being returned or deactivated. With the change of rules in the sector, in December 2021, there were already requests to open of new tracks, in 64 requests for implementation of new railways. Nine new railroads had already been authorized by the Federal Government, in of new tracks. Total actual network: 29,888 km of railroad and 1,411 km of subway and light rail Broad gauge: 4,932 km gauge (939 km electrified) Narrow gauge: 23,341 km gauge (24 km electrified) Dual gauge: 396 km 1000 mm and 1600 mm gauges (three rails) Standard gauge: 194 km gauge (2014) Estrada de Ferro do Amapá in the middle of the Amazon Rainforest also used standard gauge. A 12 km section of the former gauge Estrada de Ferro Oeste de Minas is retained as a heritage railway. Metros and light rail transit (combined) Railway links with adjacent countries International rail links exist between Brazil and Argentina, Bolivia and Uruguay. Tramways Brazil had a hundred tramway systems. Currently, there are vintage tramways operating in Belém, Campinas, Campos do Jordão, Itatinga, Rio de Janeiro and Santos. Highways Brazil has more than of roads, of which are paved (12,4%), and about are divided highways, only in the State of São Paulo. Currently it is possible to travel from Rio Grande, in the extreme south of the country, to Brasília () or Casimiro de Abreu, in the state of Rio de Janeiro (), only on divided highways. The total of paved roads increased from 35,496 km (22,056 mi) in 1967 to 215,000 km (133,595 mi) in 2018. The two most important highways in the country are BR-101 and BR-116. Although Brazil has the largest duplicated road network in Latin America, it's considered insufficient for the country's needs: in 2021, it was calculated that the ideal amount of duplicated roads would be something around from to . The main road axes also have problems because they often have inadequate geometry and constructive characteristics that don't allow quality long-distance flow (non-interference from local traffic and high speed). The Brazilian Federal Government has never implemented a National Highway Plan at the same level as developed countries such as the USA, Japan or European countries, which specifically aimed at inter-regional travel, and which should preferably be served by highways (which would differ from the common duplicated highways by geometric pattern, access control without access to neighboring lots, zero level crossings and returns, prohibition of circulation of non-motorized vehicles such as cyclists, animal traction or human propulsion, as per the Vienna Convention). The Brazilian State, despite some planning efforts, has been guided by a reactive action to the increase in demand (only duplicating some roads with old and inadequate layout) and not by a purposeful vision, directing occupation and economic density in the territory. Another problem is the lack of directing the Union Budget towards infrastructure works: in Brazil there is no law that guarantees funds from the Federal Budget for works on highways and other modes of transport (unlike what happens in sectors such as Education and Health), depending exclusively on the goodwill of the rulers. In the US, for example, the gasoline tax can only be used for transport infrastructure works. Brazil even invested 1.5% of the country's budget in infrastructure in the 1970s, being the time when the most investment was made in highways; but in the 1990s, only 0.1% of the budget was invested in this sector, maintaining an average of 0.5% in the 2000s and 2010, insufficient amounts for the construction of an adequate road network. For comparative purposes, the average investment of the USA and the European Union was 1% between 1995 and 2013, even though they already have a much more advanced road infrastructure than Brazil. The country has a medium rate of car ownership of 471 per 1000 people, however in comparison to the other developing economies of the BRIC group Brazil exceeds India and China. The country still has several states where paved access to 100% of the state's municipalities has not yet been reached. Some states have 100% of cities with asphalt access, such as Santa Catarina, which reached this goal in 2014; Paraíba, which reached this goal in 2017, and Alagoas, which reached this goal in 2021 In states like Rio Grande do Sul, in 2020, there were still 54 cities without asphalt access. In Paraná, in 2021, there were still 4 cities without asphalt access. In Minas Gerais, in 2016, there were still 5 cities without asphalt access. Waterways 50,000 km navigable (most in areas remote from industry or population) (2012) Among the main Brazilian waterways, two stand out: Hidrovia Tietê-Paraná (which has a length of 2,400 km, 1,600 on the Paraná River and 800 km on the Tietê River, draining agricultural production from the states of Mato Grosso, Mato Grosso do Sul, Goiás and part of Rondônia, Tocantins and Minas Gerais) and Hidrovia do Solimões-Amazonas (it has two sections: Solimões, which extends from Tabatinga to Manaus, with approximately 1600 km, and Amazonas, which extends from Manaus to Belém, with 1650 km. Almost entirely passenger transport from the Amazon plain is done by this waterway, in addition to practically all cargo transportation that is directed to the major regional centers of Belém and Manaus). In Brazil, this transport is still underutilized: the most important waterway stretches, from an economic point of view, are found in the Southeast and South of the country. Its full use still depends on the construction of locks, major dredging works and, mainly, of ports that allow intermodal integration.

Foreign relations of Brazil

The Ministry of Foreign Affairs is responsible for managing the foreign relations of Brazil. Brazil is a significant political and economic power in Latin America and a key player on the world stage. Brazil's foreign policy reflects its role as a regional power and a potential world power and is designed to help protect the country's national interests, national security, ideological goals, and economic prosperity. Between World War II and 1990, both democratic and military governments sought to expand Brazil's influence in the world by pursuing a state-led industrial policy and an independent foreign policy. Brazilian foreign policy has recently aimed to strengthen ties with other South American countries, engage in multilateral diplomacy through the United Nations and the Organization of American States, and act at times as a countervailing force to U.S. political and economic influence in Latin America. Overview The President has ultimate authority over foreign policy, while Congress is tasked with reviewing and considering all diplomatic nominations and international treaties, as well as legislation relating to Brazilian foreign policy. The Ministry of Foreign Affairs, also known as Itamaraty, is the government department responsible for advising the President and conducting Brazil's foreign relations with other countries and international bodies. Itamaraty's scope includes political, commercial, economic, financial, cultural and consular relations, areas in which it performs the classical tasks of diplomacy: represent, inform and administer. Foreign policy priorities are established by the President. Foreign policy Brazil's foreign policy is a by-product of the country's unique position as a regional power in Latin America, a leader among developing countries, and an emerging world power. Brazilian foreign policy has generally been based on the principles of multilateralism, peaceful dispute settlement, and non-intervention in the affairs of other countries. Brazil engages in multilateral diplomacy through the Organization of American States and the United Nations, and has increased ties with developing countries in Africa and Asia. Brazil is currently commanding a multinational U.N. stabilization force in Haiti, the MINUSTAH. Instead of pursuing unilateral prerogatives, Brazilian foreign policy has tended to emphasize regional integration, first through the Southern Cone Common Market (Mercosul) and now the Union of South American Nations. Brazil is also committed to cooperation with other Portuguese-speaking nations through joint-collaborations with the rest of the Portuguese-speaking world, in several domains which include military cooperation, financial aid, and cultural exchange. This is done in the framework of CPLP, for instance. Lula da Silva visit to Africa in 2003 included State visits to three Portuguese-speaking African nations (Angola, São Tomé and Príncipe, and Mozambique). Finally, Brazil is also strongly committed in the development and restoration of peace in East Timor, where it has a very powerful influence. Brazil's political, business, and military ventures are complemented by the country's trade policy. In Brazil, the Ministry of Foreign Relations continues to dominate trade policy, causing the country's commercial interests to be (at times) subsumed by a larger foreign policy goal, namely, enhancing Brazil's influence in Latin America and the world. For example, while concluding meaningful trade agreements with developed countries (such as the United States and the European Union) would probably be beneficial to Brazil's long-term economic self-interest, the Brazilian government has instead prioritized its leadership role within Mercosul and expanded trade ties with countries in Africa, Asia and the Middle East. Brazil's soft power diplomacy involves institutional strategies such as the formation of diplomatic coalitions to constrain the power of the established great powers. In recent years, it has given high priority in establishing political dialogue with other strategic actors such as India, Russia, China and South Africa through participation in international groupings such as BASIC, IBSA and BRICS. The BRICS states have been amongst the most powerful drivers of incremental change in world diplomacy and they benefit most from the connected global power shifts. Workers Party administration: 2003-2018 The Brazilian foreign policy under the Lula da Silva administration (2003-2010) focused on the following directives: to contribute toward the search for greater equilibrium and attenuate unilateralism; to strengthen bilateral and multilateral relations in order to increase the country's weight in political and economic negotiations on an international level; to deepen relations so as to benefit from greater economical, financial, technological and cultural interchange; to avoid agreements that could jeopardize development in the long term. These directives implied precise emphasis on: the search for political coordination with emerging and developing countries, namely India, South Africa, Russia and China; creation of the Union of South American Nations and its derivative bodies, such as the South American Security Council; strengthening of Mercosul; projection at the Doha Round and WTO; maintenance of relations with developed countries, including the United States; undertaking and narrowing of relations with African countries; campaign for the reform of the United Nations Security Council and for a permanent seat for Brazil; and defense of social objectives allowing for a greater equilibrium between the States and populations. The foreign policy of the Rousseff administration (2011-2016) sought to deepen Brazil's regional commercial dominance and diplomacy, expand Brazil's presence in Africa, and play a major role in the G20 on global warming and in other multilateral settings. At the United Nations, Brazil continues to oppose Economic sanctions and foreign military intervention, while seeking to garner support for a permanent seat at the Security Council. Cooperation with other emerging powers remain a top priority in Brazil's global diplomatic strategy. On the recent airstrike resolution supporting military action in Libya, Brazil joined fellow BRICS in the Council and abstained. On the draft resolution condemning violence in Syria, Brazil worked with India and South Africa to try to bridge the Western powers' divide with Russia and China. Bolsonaro administration, 2019-2022 After Rousseff's impeachment, Brazil started reconnecting with its western allies. In 2019 Jair Bolsonaro succeeded Michel Temer. The new foreign policy focused on a reapprochement with major governments especially the United States and Colombia in the Americas; Israel, Japan and South Korea in Asia; United Kingdom, Italy and Greece in Europe. The Brazil–Portugal relations were also strengthened, and despite disagreements over the crisis in Venezuela, Brazil remained close to the BRICS countries. During the 2018 presidential campaign, Bolsonaro said he would make considerable changes to Brazil's foreign relations, saying that the "Itamaraty needs to be in service of the values that were always associated with the Brazilian people". He also said that the country should stop "praising dictators" and attacking democracies, such as the United States, Israel and Italy. In early 2018, he affirmed that his "trip to the five democratic countries the United States, Israel, Japan, South Korea, and Taiwan showed who we will be and we would like to join good people". Bolsonaro has shown distrust towards China throughout the presidential campaign claiming they "[want to] buy Brazil", although Brazil recorded a US$20 billion trade surplus with China in 2018, and China is only the 13th largest source of foreign direct investment into Brazil. Bolsonaro said he wishes to continue to have business with the Chinese but he also said that Brazil should "make better [economic] deals" with other countries, with no "ideological agenda" behind it. His stance towards China has also been interpreted as an attempt to curry favor from the Trump administration to garner concessions from the US. However, Bolsonaro has mostly changed his position on China after he took office, saying that the two countries were "born to walk together" during his visit to Beijing in October 2019. He has also said that Brazil will stay out of the ongoing China-U.S. trade war. Bolsonaro said that his first international trip as president would be to Israel. Bolsonaro also said that the State of Palestine "is not a country, so there should be no embassy here", adding that "you don't negotiate with terrorists." The announcement was warmly received by the prime minister of Israel, Benjamin Netanyahu, who welcomed Bolsonaro to Israel in March 2019 during the final weeks of a re-election campaign, but was met with condemnation from the Arab League, which warned Bolsonaro it could damage diplomatic ties. "I love Israel," Bolsonaro said in Hebrew at a welcoming ceremony, with Netanyahu at his side, at Tel Aviv's Ben-Gurion airport. Bolsonaro also praised U.S. President Donald Trump and his foreign policy, and has been called "the tropical Trump". His son Eduardo has indicated that Brazil should distance itself from Iran, sever ties with Nicolás Maduro's government in Venezuela and relocate Brazil's embassy in Israel to Jerusalem. Bolsonaro is widely considered the most pro-American candidate in Brazil since the 1980s. PSL members said that if elected, he would dramatically improve relations between the United States and Brazil. During an October 2017 campaign rally in Miami, he saluted the American flag and led chants of "USA! USA!" to a large crowd. U.S. National Security Advisor John Bolton praised Bolsonaro as a "like-minded" partner and said his victory was a "positive sign" for Latin America. At the regional level, Bolsonaro praised Argentine President Mauricio Macri for ending the 12-year rule of Néstor and Cristina Fernández de Kirchner, which he saw as similar to Lula and Rousseff. Although he does not have plans to leave the Mercosur, he criticized it for prioritizing ideological issues over economic ones. A staunch anti-communist, Bolsonaro has condemned Cuba's former leader Fidel Castro and the current regime in that island. Bolsonaro praised British Prime Minister Winston Churchill, saying that he had learned from Churchill: "Patriotism, love for your fatherland, respect for your flag – something that has been lost over the last few years here in Brazil... and governing through example, especially at that difficult moment of the Second World War." Bolsonaro said he's open to the possibility of hosting a U.S. military base in Brazil to counter Russian influence in the region. With the intention to persuade Trump to make Brazil a NATO member in March 2019, Bolsonaro said: "the discussions with the United States will begin in the coming months". With formal U.S. support for Brazil's entry to OECD in May 2019, Bolsonaro said, "currently, all 36 members of the organization support the entry of the country, fruit of confidence in the new Brazil being built, more free, open and fair". In October 2019, on a state visit to China, he announced the end of the need for visas for Chinese and Indian entry into Brazil. Brazil had already removed the need for visas for people from the U.S., Canada, Japan, and Australia. Regional policy Over the first decade of the 21st century, Brazil has firmly established itself as a regional power. It has traditionally, if controversially, been a leader in the inter-American community and played an important role in collective security efforts, as well as in economic cooperation in the Western Hemisphere. Brazilian foreign policy supports economic and political integration efforts in order to reinforce long-standing relationships with its neighbors. It is a founding member of the Organization of American States (OAS) and the Inter-American Treaty of Reciprocal Assistance (Rio Treaty). It has given high priority to expanding relations with its South American neighbors and strengthening regional bodies such as the Latin American Integration Association (ALADI), the Union of South American Nations (UNASUR) and Mercosur. Although integration is the primary purpose of these organizations, they also serve as forums in which Brazil can exercise its leadership and develop consensus around its positions on regional and global issues. Most scholars agree that by promoting integration through organizations like Mercosur and UNASUR, Brazil has been able to solidify its role as a regional power. In addition to consolidating its power within South America, Brazil has sought to expand its influence in the broader region by increasing its engagement in the Caribbean and Central America., although some think this is still a fragile, ongoing process, that can be thwarted by secondary regional powers in South America. In April 2019 Brazil left Union of South American Nations (Unasur) to become a member of Forum for the Progress and Development of South America (Prosur). In January 2020, Brazil suspended its participation in the Community of Latin American and Caribbean States, (Celac). Brazil regularly extends export credits and university scholarships to its Latin American neighbors. In recent years, the Brazilian Development Bank (BNDES) has provided US$5 billion worth of loans to countries in the region. Brazil has also increasingly provided Latin American nations with financial aid and technical assistance. Between 2005 and 2009, Cuba, Haiti, and Honduras were the top three recipients of Brazilian assistance, receiving over $50 million annually. In November 2019, Brazil made a historic move to break with the rest of Latin America on the U.S. embargo of Cuba, becoming the first Latin American country in twenty-six years to vote against condemning the U.S.-led embargo of Cuba at the United Nations General Assembly. United Nations politics Brazil is a founding member of the United Nations and participates in all of its specialized agencies. It has participated in 33 United Nations peacekeeping missions and contributed with over 27,000 soldiers. Brazil has been a member of the United Nations Security Council ten times, most recently 2010–2011. Along with Japan, Brazil has been elected more times to the Security Council than any other U.N. member state. Brazil is currently seeking a permanent seat on the United Nations Security Council. It is a member of the G4, an alliance among Brazil, Germany, India, and Japan for the purpose of supporting each other's bids for permanent seats on the Security Council. They propose the Security Council be expanded beyond the current 15 members to include 25 members. The G4 countries argue that a reform would render the body "more representative, legitimate, effective and responsive" to the realities of the international community in the 21st century. Outstanding international issues Two short sections of the border with Uruguay are in dispute - the Arroio Invernada area of the Quaraí River, and the Brazilian Island at the confluence of the Quaraí River and the Uruguay River. Brazil declared in 1986 the sector between 28°W to 53°W Brazilian Antarctica (Antártica Brasileira) as its Zone of Interest. It overlaps Argentine and British claims In 2004, the country submitted its claims to the United Nations Commission on the Limits of the Continental Shelf (CLCS) to extend its maritime continental margin. Foreign aid Overseas aid has become an increasingly important tool for Brazil's foreign policy. Brazil provides aid through the Brazilian Agency of Cooperation (Abbreviation: ABC; ), in addition to offering scientific, economical, and technical support. More than half of Brazilian aid is provided to Africa, whereas Latin America receives around 20% of Brazilian aid. The share of aid allocated to the Asian continent is small. Within Africa, more than 80% of Brazilian aid is received by Portuguese-speaking countries. Brazil concentrates its aid for Portuguese-speaking countries in the education sector, specially in secondary and post-secondary education, but it is more committed to agricultural development in other countries. Estimated to be around $1 billion annually, Brazil is on par with China and India and ahead of many more traditional donor countries. The aid tends to consist of technical aid and expertise, alongside a quiet non-confrontational diplomacy to development results. Brazil's aid demonstrates a developing pattern of South-South aid, which has been heralded as a 'global model in waiting'. Concomitantly, South-South relations have become a major subfield of specialisation among Brazilian foreign policy experts. Some studies have suggested that, by giving aid, Brazil could be trying to get access to mineral and energy resources.

Economy of the British Virgin Islands

The economy of the British Virgin Islands is one of the most prosperous in the Caribbean. Although tiny in absolute terms, because of the very small population of the British Virgin Islands, in 2010 the Territory had the 19th highest GDP per capita in the world according to the CIA World factbook. In global terms the size of the Territory's GDP measured in terms of purchasing power is ranked as 215th out of a total of 229 countries. The economy of the Territory is based upon the "twin pillars" of financial services, which generates approximately 60% of government revenues, and tourism, which generates nearly all of the rest. Historically the British Virgin Islands has normally produced a Government budget surplus, but during the financial crisis of 2007–2008 the Territory began to run at a deficit, which continued after the global recession receded. In 2011 the Territory had its largest ever budget deficit, of US$29 million (approximately 2.6% of GDP). By 2012 public debt had quadrupled from pre-crisis levels to approximately US$113 million (approximately 10.3% of GDP). Nearly 84% of that public debt was attributable to a new public hospital built in Road Town between 2003 and 2014. The Economist argued that deteriorating economic conditions in the British Virgin Islands were caused "not [by] sagging revenues but public-sector profligacy". By 2014 public debt had been reduced to US$106 million and the annual deficit reduced to US$25 million (including budgeted capital expenditure). By 2016, the Government had returned to a primary budget surplus, but public debt had increased to approximately US$141 million and debt service accounted for over US$12 million of the primary surplus. However, because of an ongoing aggressive capital investment programme, and budget overruns on key public projects, the Government ran dangerously low on available cash. Cash in the consolidated fund fell below US$7 million (with average monthly expenditure at nearly US$30 million), and Government accrued over US$13 million in due but unpaid invoices. Business environment In 2015, British Virgin Islands has been assessed as the 34th in terms of global financial centres. This was the highest ranking of any offshore financial centre, and of any Latin American country. The Territory scored strongly in areas such as local taxation, rule of law, regulatory environment and quality of law for human resources. It scored less highly on infrastructure, access to capital and access to labour. The G-20 considers it a tax haven and its banking system is described as 'opaque'. 2017 Government Budget The most recent national budget to be delivered was the 2017 budget (the Territory's fiscal year runs from 1 April to 31 March). That budget presented a picture of declining revenues and increasing costs. It was also delivered prior to the devastating effects of Hurricane Irma later in the year, which is likely to have a deleterious effect on the economy and on Government revenues. The 2017 budget predicted that 2016 final revenue figures of $310,470,000 which was a decrease of 6.2% from the year before. It also predicted recurrent expenditure for 2016 at $288,640,000 which was an increase of 3.6% on the preceding year. That would mean a primary budget surplus of $21,830,000 which would be a decrease of 56.6% from the preceding year. In addition there was an estimated $21,000,000 of capital expenditure in 2016 (down 38.3% from the previous year), and debt service of $20,200,000 leaving a primary deficit of $19,370,000. In 2017, after accounting for transfers to reserves, there is budgeted to be a structural deficit of $31,674,000. This was to be financed by new borrowing and transfers from the consolidated fund. The Government's total borrowings were $106.5 million, but the Government has also underwritten significant loans made to the BVI Electricity Corporation and the BVI Ports Authority, meaning that the Government's total loan exposure is $178.3 million. Much of the Government's increased expenditure arose from staffing costs. Staffing consumes 37.7% of Government expenditure, and increased in 2016 by 10.2% from the year before. The budget calls for it to increase again, but only by 2.6% in 2017. The bulk of Government revenues (60%) comes from taxes on goods and services. The next largest segment is payroll taxes, which account for a further 16%. Property taxes account for less than 1% of revenue. Tourism In 2015, a total of 922,372 people visited the islands (of whom 529,354 were cruise ship passengers and 393,018 were overnight visitors), mainly from the United States. The bulk of the tourism income in the British Virgin Islands is generated by the yacht chartering industry. The Territory has relatively few large hotels compared to other tourism centres in the Caribbean. The British Virgin Islands also entertain cruise ships, although these generate relatively little revenue. However, cruise ship passengers are an important source of revenue for taxi drivers, who represent a politically important voice in the Territory. Between 2007 and 2011, tourist visitors to be the British Virgin Islands declined by approximately 12.4%, largely due to the global recession which particularly affected North America, a key source of visitors for the Territory. However, by November 2013 tourist numbers had begun to recover. According to the World Travel and Tourism Council: In 2013, the direct contribution of travel and tourism to the Territory's GDP was US$274 million (accounting for 27.0% of total GDP), and was forecast to rise by 2.8% in 2014, and to rise by 2.7% per annum for the period 2014–2024. The total contribution of travel and tourism to GDP was US$780.8 million (76.9% of GDP) in 2013, and is forecast to rise by 3.2% in 2014, and to rise by 2.6% per annum for the period 2014–2024. In 2013, travel and tourism directly supported 3,300 jobs in the Territory (33.2% of total employment). This was expected to remain unchanged in 2014 and fall by 0.3% per annum to 3,000 jobs (29.6% of total employment) by 2024. The total contribution to employment in 2013 (which includes jobs indirectly supported by the industry), was 90.1% of total employment (8,850 jobs). This was expected to rise by 1.9% in 2014 to 9,050 jobs, but fall by 0.2% per annum to 9,000 jobs in 2024 (80.9% of total). Travel and tourism investment in 2013 was US$35.8 million, or 14.8% of total investment. This was expected to rise by 10.1% in 2014, and rise by 2.0% per annum over the next ten years to a total of US$48.2 million in 2024. However, these statistics include travel as well as tourism, and so non-tourist related travel (i.e. travel relating to domestic consumption and other industries and services) are included and inflate the figures. Financial services In the mid-1980s, the government began offering offshore registration to companies wishing to incorporate in the islands, and incorporation fees now generate an estimated 51.4% of Government revenues. As of 2019, it costs $450 to form a company with fewer than 50,000 shares and another $450 a year to maintain registration. According to official statistics 447,801 BVI companies were 'active' (i.e. incorporated and not yet struck-off, liquidated or dissolved) as at 30 June 2012. There are no recent official statistics on total numbers of incorporations (including struck, liquidated and dissolved companies) but these are estimated at approximately 950,000. Many of these companies were originally formed under the International Business Companies Act, 1984, but have now been consolidated into the BVI Business Companies Act, 2004. In 2000, KPMG were commissioned by the British Government to produce a report on the offshore financial industry generally, and the report indicated that nearly 45% of the offshore companies in the world were formed in the British Virgin Islands. The British Virgin Islands is now one of the world's leading offshore financial centres, and boasts one of the highest incomes per capita in the Caribbean. In addition to basic company incorporations, the British Virgin Islands also forms limited partnerships and trusts (including signature "VISTA" trusts) but these have not proved to be as popular as companies. On 12 April 2007, the Financial Times reported that the British Virgin Islands was the second largest source of foreign direct investment in the world (behind Hong Kong) with over US$123,000,000,000. Almost all of these sums are directly attributable to investment through the Territory's offshore finance industry. The British Virgin Islands also promotes a number of regulated financial services products. The most important of these is the formation and regulation of offshore investment funds. The Territory is also the second largest domicile for formation of offshore investment funds (behind the Cayman Islands) with 2,422 licensed open-ended funds as at 30 June 2012 (there is no official statistics for closed-ended funds which are not regulated in the British Virgin Islands). The British Virgin Islands also operates as a domicile for captive insurance services, but a prolonged period of overzealous Government regulation combined with the Government's increasing pressure to hire only locals ("belongers") in the insurance industry decimated the industry. Official reports from the Financial Services Commission reflect as of 30 June 2012 only 161 captives remain registered in the jurisdiction. History of financial services Former president of the BVI's Financial Services Commission, Michael Riegels, recites the anecdote that the offshore finance industry commenced on an unknown date in the 1970s when a lawyer from a firm in New York telephoned him with a proposal to incorporate a company in the British Virgin Islands to take advantage of a double taxation relief treaty with the United States. Within the space of a few years, hundreds of such companies had been incorporated. This eventually came to the attention of the United States government, who unilaterally revoked the Treaty in 1981. In 1984, the British Virgin Islands, trying to recapture some of the lost offshore business, enacted a new form of companies legislation, the International Business Companies Act, under which an offshore company which was exempt from local taxes could be formed. The development was only a limited success until 1991, when the United States invaded Panama to oust General Manuel Noriega. At the time Panama was one of the largest providers of offshore financial services in the world, but the business fled subsequent the invasion, and the British Virgin Islands was one of the main beneficiaries. Agriculture Livestock raising is the most important agricultural activity; poor soils limit the islands' ability to meet domestic food requirements. Fewer than 0.6% are estimated to work in agriculture. Despite its tiny economic impact, agriculture has its own dedicated Government minister (unlike financial services). Dollarisation Because of traditionally close links with the U.S. Virgin Islands, the British Virgin Islands has used the US dollar as its currency since 1959.
