paragraph_text: In the 1520s during the Protestant Reformation, the city, under the political guidance of Jacob Sturm von Sturmeck and the spiritual guidance of Martin Bucer embraced the religious teachings of Martin Luther. Their adherents established a Gymnasium, headed by Johannes Sturm, made into a University in the following century. The city first followed the Tetrapolitan Confession, and then the Augsburg Confession. Protestant iconoclasm caused much destruction to churches and cloisters, notwithstanding that Luther himself opposed such a practice. Strasbourg was a centre of humanist scholarship and early book-printing in the Holy Roman Empire, and its intellectual and political influence contributed much to the establishment of Protestantism as an accepted denomination in the southwest of Germany. (John Calvin spent several years as a political refugee in the city). The Strasbourg Councillor Sturm and guildmaster Matthias represented the city at the Imperial Diet of Speyer (1529), where their protest led to the schism of the Catholic Church and the evolution of Protestantism. Together with four other free cities, Strasbourg presented the confessio tetrapolitana as its Protestant book of faith at the Imperial Diet of Augsburg in 1530, where the slightly different Augsburg Confession was also handed over to Charles V, Holy Roman Emperor.

paragraph_text: The site of the Forbidden City was situated on the Imperial city during the Mongol Yuan Dynasty. After the collapse of the Yuan Dynasty, the Hongwu Emperor of the Ming Dynasty moved the capital from Beijing in the north to Nanjing in the south, and in 1369 ordered that the Yuan palaces be razed. His son Zhu Di was created Prince of Yan with his seat in Beijing. In 1402, Zhu Di usurped the throne and became the Yongle Emperor. He made Beijing a secondary capital of the Ming empire, and construction began in 1406 of what would become the Forbidden City. The Forbidden City's plan was designed by many architects and designers, and then it was examined by the Emperor's Ministry of Work. The chief architects and engineers include Cai Xin, Nguyen An, a Vietnamese eunuch, Kuai Xiang, Lu Xiang and others.

paragraph_text: The winner, Taira no Kiyomori, became an imperial advisor, and was the first warrior to attain such a position. He eventually seized control of the central government, establishing the first samurai-dominated government and relegating the Emperor to figurehead status. However, the Taira clan was still very conservative when compared to its eventual successor, the Minamoto, and instead of expanding or strengthening its military might, the clan had its women marry Emperors and exercise control through the Emperor.

paragraph_text: Constantinople had been an imperial capital since its consecration as the first Christian capital in 330 under the first Christian Roman emperor, Constantine the Great. In the following eleven centuries, the city had been besieged many times but was captured only once: during the Fourth Crusade in 1204. The crusaders established an unstable Latin state in and around Constantinople while the remaining empire splintered into a number of Byzantine successor states, notably Nicaea, Epirus and Trebizond. They fought as allies against the Latin establishments, but also fought among themselves for the Byzantine throne.

paragraph_text: However, civil war flared again when the Second Triumvirate of Octavian, Lepidus and Mark Antony failed. The ambitious Octavian built a power base of patronage and then launched a campaign against Mark Antony. At the naval Battle of Actium off the coast of Greece, Octavian decisively defeated Antony and Cleopatra. Octavian was granted a series of special powers including sole "imperium" within the city of Rome, permanent consular powers and credit for every Roman military victory, since all future generals were assumed to be acting under his command. In 27 BC Octavian was granted the use of the names "Augustus" and "Princeps", indicating his primary status above all other Romans, and he adopted the title "Imperator Caesar" making him the first Roman Emperor.

paragraph_text: The Inca Empire (Quechua: Tawantinsuyu, lit. ``The Four Regions ''), also known as the Incan Empire and the Inka Empire, was the largest empire in pre-Columbian America, and possibly the largest empire in the world in the early 16th century. The administrative, political and military center of the empire was located in Cusco in modern - day Peru. The Inca civilization arose from the highlands of Peru sometime in the early 13th century. Its last stronghold was conquered by the Spanish in 1572.

paragraph_text: The Diet of Worms 1521 (German: Reichstag zu Worms (ˈʁaɪçstaːk tsuː ˈvɔɐms)) was an imperial diet (assembly) of the Holy Roman Empire called on by King Charles V. It was held at the Heylshof Garden in Worms, then an Imperial Free City of the Empire. An imperial diet was a formal deliberative assembly of the whole Empire. This one is most memorable for the Edict of Worms (Wormser Edikt), which addressed Martin Luther and the effects of the Protestant Reformation. It was conducted from 28 January to 25 May 1521, with the Emperor Charles V presiding.

paragraph_text: On 25 December 800, Pope Leo III crowned the Frankish king Charlemagne as Emperor, reviving the title in Western Europe, more than three centuries after the fall of the earlier ancient Western Roman Empire in 476. The title continued in the Carolingian family until 888 and from 896 to 899, after which it was contested by the rulers of Italy in a series of civil wars until the death of the last Italian claimant, Berengar I, in 924. The title was revived again in 962 when Otto I was crowned emperor, fashioning himself as the successor of Charlemagne and beginning a continuous existence of the empire for over eight centuries. Some historians refer to the coronation of Charlemagne as the origin of the empire, while others prefer the coronation of Otto I as its beginning. Scholars generally concur, however, in relating an evolution of the institutions and principles constituting the empire, describing a gradual assumption of the imperial title and role.

paragraph_text: The Forbidden City is a palace complex in central Beijing, China. The former Chinese imperial palace from the Ming dynasty to the end of the Qing dynasty -- the years 1420 to 1912, it now houses the Palace Museum. The Forbidden City served as the home of emperors and their households as well as the ceremonial and political center of Chinese government for almost 500 years.

paragraph_text: The imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. The first two centuries of the empire's existence were a period of unprecedented political stability and prosperity known as the Pax Romana, or ``Roman Peace ''. Following Octavian's victory, the size of the empire was dramatically increased. After the assassination of Caligula in AD 41, the Senate briefly considered restoring the republic, but the Praetorian Guard proclaimed Claudius emperor instead. Under Claudius, the empire invaded Britannia, its first major expansion since Augustus. After Claudius' successor, Nero, committed suicide in AD 68, the empire suffered a series of brief civil wars, as well as a concurrent major rebellion in Judea, during which four different legionary generals were proclaimed emperor. Vespasian emerged triumphant in AD 69, establishing the Flavian dynasty, before being succeeded by his son Titus, who opened the Colosseum shortly after the eruption of Mount Vesuvius. His short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. The Senate then appointed the first of the Five Good Emperors. The empire reached its greatest extent under Trajan, the second in this line.

paragraph_text: Under Charlemagne the Franks reached the height of their power. After campaigns against Lombards, Avars, Saxons, and Basques, the resulting Carolingian Empire stretched from the Pyrenees to Central Germany, from the North Sea to the Adriatic. In 800 the Pope made Charlemagne Emperor of the West in return for protection of the Church. The Carolingian Empire was a conscious effort to recreate a central administration modeled on that of the Roman Empire,[13] but the motivations behind military expansion differed. Charlemagne hoped to provide his nobles an incentive to fight by encouraging looting on campaign. Plunder and spoils of war were stronger temptations than imperial expansion, and several regions were invaded over and over in order to bolster the coffers of Frankish nobility.[14] Cavalry dominated the battlefields, and while the high costs associated with equipping horses and horse-riders helped limit their numbers, Carolingian armies maintained an average size of 20,000 by recruiting infantry from imperial territories near theaters of operation.[15] The Empire lasted from 800 to 843, when, following Frankish tradition, it was split between the sons of Louis the Pious by the Treaty of Verdun.

paragraph_text: For almost a thousand years, Rome was the most politically important, richest and largest city in Europe. Around 100 CE, it had a population of about 450,000, and declined to a mere 20,000 during the Early Middle Ages, reducing the sprawling city to groups of inhabited buildings interspersed among large areas of ruins and vegetation.

paragraph_text: In the early Heian period, the late 8th and early 9th centuries, Emperor Kammu sought to consolidate and expand his rule in northern Honshū, but the armies he sent to conquer the rebellious Emishi people lacked motivation and discipline, and failed in their task.[citation needed] Emperor Kammu introduced the title of sei'i-taishōgun (征夷大将軍) or Shogun, and began to rely on the powerful regional clans to conquer the Emishi. Skilled in mounted combat and archery (kyūdō), these clan warriors became the Emperor's preferred tool for putting down rebellions.[citation needed] Though this is the first known use of the "Shogun" title, it was a temporary title, and was not imbued with political power until the 13th century. At this time (the 7th to 9th century) the Imperial Court officials considered them merely a military section under the control of the Imperial Court.

paragraph_text: Charlemagne (/ ˈʃɑːrlɪmeɪn /) or Charles the Great (2 April 742 -- 28 January 814), numbered Charles I, was King of the Franks from 768, King of the Lombards from 774 and Emperor of the Romans from 800. He united much of Europe during the early Middle Ages. He was the first recognised emperor in western Europe since the fall of the Western Roman Empire three centuries earlier. The expanded Frankish state that Charlemagne founded is called the Carolingian Empire.

paragraph_text: On the Indian subcontinent, the Mughal Empire ruled most of India in the early 18th century. The "classic period" ended with the death and defeat of Emperor Aurangzeb in 1707 by the rising Hindu Maratha Empire, although the dynasty continued for another 150 years. During this period, the Empire was marked by a highly centralized administration connecting the different regions. All the significant monuments of the Mughals, their most visible legacy, date to this period which was characterised by the expansion of Persian cultural influence in the Indian subcontinent, with brilliant literary, artistic, and architectural results. The Maratha Empire was located in the south west of present-day India and expanded greatly under the rule of the Peshwas, the prime ministers of the Maratha empire. In 1761, the Maratha army lost the Third Battle of Panipat which halted imperial expansion and the empire was then divided into a confederacy of Maratha states.

It was conducted from 28 January to 26 May 1521, with the Emperor Charles V presiding.

paragraph_text: As the Soga clan had taken control of the throne in the sixth century, the Fujiwara by the ninth century had intermarried with the imperial family, and one of their members was the first head of the Emperor's Private Office. Another Fujiwara became regent, Sesshō for his grandson, then a minor emperor, and yet another was appointed Kampaku. Toward the end of the ninth century, several emperors tried, but failed, to check the Fujiwara. For a time, however, during the reign of Emperor Daigo (897-930), the Fujiwara regency was suspended as he ruled directly.

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: The most recognizable icon of Mexico City is the golden Angel of Independence on the wide, elegant avenue Paseo de la Reforma, modeled by the order of the Emperor Maximilian of Mexico after the Champs-Élysées in Paris. This avenue was designed over the Americas' oldest known major roadway in the 19th century to connect the National Palace (seat of government) with the Castle of Chapultepec, the imperial residence. Today, this avenue is an important financial district in which the Mexican Stock Exchange and several corporate headquarters are located. Another important avenue is the Avenida de los Insurgentes, which extends 28.8 km (17.9 mi) and is one of the longest single avenues in the world.

paragraph_text: Historians often refer to the period from Qin dynasty to the end of Qing dynasty as Imperial China. Though the unified reign of the First Qin Emperor lasted only 12 years, he managed to subdue great parts of what constitutes the core of the Han Chinese homeland and to unite them under a tightly centralized Legalist government seated at Xianyang (close to modern Xi'an). The doctrine of Legalism that guided the Qin emphasized strict adherence to a legal code and the absolute power of the emperor. This philosophy, while effective for expanding the empire in a military fashion, proved unworkable for governing it in peacetime. The Qin Emperor presided over the brutal silencing of political opposition, including the event known as the burning of books and burying of scholars. This would be the impetus behind the later Han synthesis incorporating the more moderate schools of political governance.
