paragraph_text: The Chronica Gallica of 452 records for the year 441: ``The British provinces, which to this time had suffered various defeats and misfortunes, are reduced to Saxon rule. ''The Chronicle was written some distance from Britain. There is uncertainty about precise dates for fifth - century events especially before 446. This, however, does not undermine the position of the Gallic Chronicles as a very important contemporary source, which suggests that Bede's later date for 'the arrival of the Saxons' was mistaken. In the Chronicle, Britain is grouped with four other Roman territories which came under 'Germanic' dominion around the same time, the list being intended as an explanation of the end of the Roman empire in the west. The four share a similar history, as they were all given into the`` power of the barbarians'' by Roman authority: three were deliberately settled with German federates and though the Vandals took Africa by force their dominion was confirmed by treaty.

paragraph_text: The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern - day Istanbul, which had been founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both ``Byzantine Empire ''and`` Eastern Roman Empire'' are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the Roman Empire (Greek: Βασιλεία τῶν Ῥωμαίων, tr. Basileia tôn Rhōmaiōn; Latin: Imperium Romanum), or Romania (Ῥωμανία), and to themselves as ``Romans. ''

paragraph_text: The Jardin botanique de Sedan is a botanical garden and city park located on Philippoteaux Avenue beside the Place d'Alsace-Lorraine, Sedan, Ardennes, Champagne-Ardenne, France. It is open daily without charge.

paragraph_text: As the Roman occupation of Britain was coming to an end, Constantine III withdrew the remains of the army, in reaction to the barbarian invasion of Europe. The Romano - British leaders were faced with an increasing security problem from seaborne raids, particularly by Picts on the East coast of England. The expedient adopted by the Romano - British leaders was to enlist the help of Anglo - Saxon mercenaries (known as foederati), to whom they ceded territory. In about 442 the Anglo - Saxons mutinied, apparently because they had not been paid. The Romano - British responded by appealing to the Roman commander of the Western empire, Aëtius for help (a document known as the Groans of the Britons), even though Honorius, the Western Roman Emperor, had written to the British civitas in or about 410 telling them to look to their own defence. There then followed several years of fighting between the British and the Anglo - Saxons. The fighting continued until around 500, when, at the Battle of Mount Badon, the Britons inflicted a severe defeat on the Anglo - Saxons.

paragraph_text: It has pleased western historians to write of a decline of the Ottoman Empire as though a stable and uncontested polity of that name once existed. The borders did expand and contract but they were always dynamic and always in "question" right from the beginning. The Ottoman Empire was created from the lands of the former eastern Roman Empire on the occasion of the latter's violent demise. The last Roman emperor died fighting hand-to-hand in the streets of his capital, Constantinople, overwhelmed by the Ottoman military, in May, 1453. The victors inherited his remaining territory in the Balkans.

paragraph_text: The Portuguese language is derived from the Latin spoken by the romanized Pre-Roman peoples of the Iberian Peninsula around 2000 years ago—particularly the Celts, Tartessians, Lusitanians and Iberians. In the 15th and 16th centuries, the language spread worldwide as Portugal established a colonial and commercial empire between 1415 and 1999. Portuguese is now spoken as a native language in five different continents, with Brazil accounting for the largest number of native Portuguese speakers of any country (200 million speakers in 2012).

paragraph_text: The earliest known use of the phrase Brytish Iles in the English language is dated 1577 in a work by John Dee. Today, this name is seen by some as carrying imperialist overtones although it is still commonly used. Other names used to describe the islands include the Anglo-Celtic Isles, Atlantic archipelago, British-Irish Isles, Britain and Ireland, UK and Ireland, and British Isles and Ireland. Owing to political and national associations with the word British, the Government of Ireland does not use the term British Isles and in documents drawn up jointly between the British and Irish governments, the archipelago is referred to simply as "these islands". Nonetheless, British Isles is still the most widely accepted term for the archipelago.

paragraph_text: The Seven Years' War was a global conflict fought between 1756 and 1763. It involved every European great power of the time and spanned five continents, affecting Europe, the Americas, West Africa, India, and the Philippines. The conflict split Europe into two coalitions, led by the Kingdom of Great Britain (including Prussia, Portugal, Hanover, and other small German states) on one side and the Kingdom of France (including the Austrian - led Holy Roman Empire, the Russian Empire, Bourbon Spain, and Sweden) on the other. Meanwhile, in India, the Mughal Empire, with the support of the French, tried to crush a British attempt to conquer Bengal.

paragraph_text: By the 6th century, the Rhine was within the borders of Francia. In the 9th, it formed part of the border between Middle and Western Francia, but in the 10th century, it was fully within the Holy Roman Empire, flowing through Swabia, Franconia and Lower Lorraine. The mouths of the Rhine, in the county of Holland, fell to the Burgundian Netherlands in the 15th century; Holland remained contentious territory throughout the European wars of religion and the eventual collapse of the Holy Roman Empire, when the length of the Rhine fell to the First French Empire and its client states. The Alsace on the left banks of the Upper Rhine was sold to Burgundy by Archduke Sigismund of Austria in 1469 and eventually fell to France in the Thirty Years' War. The numerous historic castles in Rhineland-Palatinate attest to the importance of the river as a commercial route.

paragraph_text: The trees and rivers of the Ardennes provided the charcoal industry assets that enabled the great industrial period of Wallonia in the 18th and 19th centuries, when it was arguably the second great industrial region of the world, after England. The greater region maintained an industrial eminence into the 20th century, after coal replaced charcoal in metallurgy.

paragraph_text: China shares international borders with 14 sovereign states. In addition, there is a 30 - km border with the special administrative region of Hong Kong, which was a British dependency before 1997, and a 3 km border with Macau, a Portuguese territory until 1999. With a land border of 22,117 kilometres (13,743 mi) in total it also has the longest land border of any country.

paragraph_text: England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five - eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south, and includes over 100 smaller named islands such as the Isles of Scilly and the Isle of Wight.

paragraph_text: Anglo-Saxons arrived as Roman power waned in the 5th century AD. Initially, their arrival seems to have been at the invitation of the Britons as mercenaries to repulse incursions by the Hiberni and Picts. In time, Anglo-Saxon demands on the British became so great that they came to culturally dominate the bulk of southern Great Britain, though recent genetic evidence suggests Britons still formed the bulk of the population. This dominance creating what is now England and leaving culturally British enclaves only in the north of what is now England, in Cornwall and what is now known as Wales. Ireland had been unaffected by the Romans except, significantly, having been Christianised, traditionally by the Romano-Briton, Saint Patrick. As Europe, including Britain, descended into turmoil following the collapse of Roman civilisation, an era known as the Dark Ages, Ireland entered a golden age and responded with missions (first to Great Britain and then to the continent), the founding of monasteries and universities. These were later joined by Anglo-Saxon missions of a similar nature.

paragraph_text: The Roman Empire came to dominate the entire Mediterranean basin in a vast empire based on Roman law and Roman legions. It promoted trade, tolerance, and Greek culture. By 300 AD the Roman Empire was divided into the Western Roman Empire based in Rome, and the Eastern Roman Empire based in Constantinople. The attacks of the Germanic peoples of northern Europe led to the Fall of the Western Roman Empire in AD 476, a date which traditionally marks the end of the classical period and the start of the Middle Ages.

paragraph_text: The Kitos War (115–117; : "mered ha'galuyot" or "mered ha'tfutzot" [מרד התפוצות]; translation: rebellion of the diaspora. ) was one of the major Jewish–Roman wars, 66–136. The rebellions erupted in the year 115, when majority of the Roman armies were fighting Trajan's Parthian War on the eastern border of the Roman Empire, major uprisings by ethnic Judeans in Cyrenaica, Cyprus and Egypt spiraled out of control, resulting in a widespread slaughter of left-behind Roman garrisons and Roman citizens by Jewish rebels.

paragraph_text: Science and technology in Wallonia, the southern region of Belgium (Europe), is well developed with the presence of several universities and research institutes.

paragraph_text: During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio - Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor, and founder of the Flavian dynasty. The Roman Empire generally experienced a period of prosperity and dominance in this period and the First Century is remembered as part of the Empire's golden age.

paragraph_text: In about 260 AD, the fall of the Agri Decumates territory north of the Rhine transformed today's Switzerland into a frontier land of the Empire. Repeated raids by the Alamanni tribes provoked the ruin of the Roman towns and economy, forcing the population to find shelter near Roman fortresses, like the Castrum Rauracense near Augusta Raurica. The Empire built another line of defense at the north border (the so-called Donau-Iller-Rhine-Limes), but at the end of the fourth century the increased Germanic pressure forced the Romans to abandon the linear defence concept, and the Swiss plateau was finally open to the settlement of German tribes.
