paragraph_text: In the face of aggressions by Napoleon I, who had been proclaimed "Emperor of the French" (French: "Empereur des Français"), by the French constitution on 18 May 1804, Francis II feared for the future of the Holy Roman Empire and wished to maintain his and his family's Imperial status in the event that the Holy Roman Empire should be dissolved. Therefore, on 11 August 1804 he created the new title of "Emperor of Austria" for himself and his successors as heads of the House of Habsburg-Lorraine. For two years, Francis carried two imperial titles: being Holy Roman Emperor Francis II and "by the Grace of God" ("Von Gottes Gnaden") Emperor Francis I of Austria.

paragraph_text: Bohemia (as Czech civilization was known by then) increased in power over the centuries, as its language did in regional importance. This growth was expedited during the fourteenth century by Holy Roman Emperor Charles IV, who founded Charles University in Prague in 1348. Here, early Czech literature (a biblical translation, hymns and hagiography) flourished. Old Czech texts, including poetry and cookbooks, were produced outside the university as well. Later in the century Jan Hus contributed significantly to the standardization of Czech orthography, advocated for widespread literacy among Czech commoners (particularly in religion) and made early efforts to model written Czech after the spoken language.

paragraph_text: The Roman legions first entered the area under Decimus Junius Brutus in 137–136 BC, but the country was only incorporated into the Roman Empire by the time of Augustus (29 BC – 19 BC). The Romans were interested in Galicia mainly for its mineral resources, most notably gold. Under Roman rule, most Galician hillforts began to be – sometimes forcibly – abandoned, and Gallaeci served frequently in the Roman army as auxiliary troops. Romans brought new technologies, new travel routes, new forms of organizing property, and a new language; latin. The Roman Empire established its control over Galicia through camps (castra) as Aquis Querquennis, Ciadella camp or Lucus Augusti (Lugo), roads (viae) and monuments as the lighthouse known as Tower of Hercules, in Corunna, but the remoteness and lesser interest of the country since the 2nd century of our era, when the gold mines stopped being productive, led to a lesser degree of Romanization. In the 3rd century it was made a province, under the name Gallaecia, which included also northern Portugal, Asturias, and a large section of what today is known as Castile and León.

paragraph_text: Wang Shen'ai was the daughter of the official Wang Xianzhi, the son of the famed official and calligrapher Wang Xizhi. Her mother Princess Xin'an was the daughter of Emperor Jianwen, making her and her husband cousins. In 396, while he was still crown prince under his father Emperor Xiaowu, they married, and she became crown empress. She was 12, and he was 14. As he was described to be so developmentally disabled that he could not speak or dress himself, or express whether he was full or hungry, it was unlikely that their marriage was consummated; in any case, they had no children. Later that year, after Emperor Xiaowu was killed by his concubine Honoured Lady Zhang after humiliating her, Emperor An became emperor. In 397, she was created empress.

paragraph_text: Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. The English monk Alcuin (d. 804) was invited to Aachen and brought the education available in the monasteries of Northumbria. Charlemagne's chancery—or writing office—made use of a new script today known as Carolingian minuscule,[M] allowing a common writing style that advanced communication across much of Europe. Charlemagne sponsored changes in church liturgy, imposing the Roman form of church service on his domains, as well as the Gregorian chant in liturgical music for the churches. An important activity for scholars during this period was the copying, correcting, and dissemination of basic works on religious and secular topics, with the aim of encouraging learning. New works on religious topics and schoolbooks were also produced. Grammarians of the period modified the Latin language, changing it from the Classical Latin of the Roman Empire into a more flexible form to fit the needs of the church and government. By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin.

paragraph_text: The coronation of Charlemagne as emperor on Christmas Day 800 is regarded as a turning point in medieval history, marking a return of the Western Roman Empire, since the new emperor ruled over much of the area previously controlled by the western emperors. It also marks a change in Charlemagne's relationship with the Byzantine Empire, as the assumption of the imperial title by the Carolingians asserted their equivalence to the Byzantine state. There were several differences between the newly established Carolingian Empire and both the older Western Roman Empire and the concurrent Byzantine Empire. The Frankish lands were rural in character, with only a few small cities. Most of the people were peasants settled on small farms. Little trade existed and much of that was with the British Isles and Scandinavia, in contrast to the older Roman Empire with its trading networks centred on the Mediterranean. The empire was administered by an itinerant court that travelled with the emperor, as well as approximately 300 imperial officials called counts, who administered the counties the empire had been divided into. Clergy and local bishops served as officials, as well as the imperial officials called missi dominici, who served as roving inspectors and troubleshooters.

paragraph_text: In addition to tributary relations with the Kushans, the Han Empire received gifts from the Parthian Empire, from a king in modern Burma, from a ruler in Japan, and initiated an unsuccessful mission to Daqin (Rome) in AD 97 with Gan Ying as emissary. A Roman embassy of Emperor Marcus Aurelius (r. 161–180 AD) is recorded in the Hou Hanshu to have reached the court of Emperor Huan of Han (r. AD 146–168) in AD 166, yet Rafe de Crespigny asserts that this was most likely a group of Roman merchants. Other travelers to Eastern-Han China included Buddhist monks who translated works into Chinese, such as An Shigao of Parthia, and Lokaksema from Kushan-era Gandhara, India.

paragraph_text: The Heian period was preceded by the Nara period and began in 794 A.D after the movement of the capital of Japan to Heian-kyō (present day Kyōto京都), by the 50th emperor, Emperor Kanmu. Kanmu first tried to move the capital to Nagaoka-kyō, but a series of disasters befell the city, prompting the emperor to relocate the capital a second time, to Heian. The Heian Period is considered a high point in Japanese culture that later generations have always admired. The period is also noted for the rise of the samurai class, which would eventually take power and start the feudal period of Japan.

paragraph_text: Constantine the Great, who along with Licinius had decreed toleration of Christianity in the Roman Empire by what is commonly called the "Edict of Milan", and was the first Roman Emperor baptized, set precedents for later policy. By Roman law the Emperor was Pontifex Maximus, the high priest of the College of Pontiffs (Collegium Pontificum) of all recognized religions in ancient Rome. To put an end to the doctrinal debate initiated by Arius, Constantine called the first of what would afterwards be called the ecumenical councils and then enforced orthodoxy by Imperial authority.

paragraph_text: Ran Zhi, as Ran Min's oldest son, was created crown prince when he proclaimed the new state in 350 after overthrowing the Later Zhao emperor Shi Jian and declared himself emperor. He created Ran Zhi's mother Lady Dong empress. After he was captured and executed by Former Yan's prince Murong Jun in 352, Empress Dong tried to hold out but was eventually forced to surrender. Murong Jun created her the Lady Fengxi and created Ran Zhi the Marquess of Haibin. In 354, the Former Yan official Song Bin (宋斌) was accused of leading a plot to have Ran Zhi made emperor, and it was said that all who were involved were executed — implying, but not explicitly stating, that Ran Zhi was executed as well. A number of officials named Ran during the later Northern Wei Dynasty claimed descent from Ran Min, presumably through Ran Zhi.

paragraph_text: Aristotle wrote in his book Meteorology about an Antarctic region in c. 350 B.C. Marinus of Tyre reportedly used the name in his unpreserved world map from the 2nd century A.D. The Roman authors Hyginus and Apuleius (1–2 centuries A.D.) used for the South Pole the romanized Greek name polus antarcticus, from which derived the Old French pole antartike (modern pôle antarctique) attested in 1270, and from there the Middle English pol antartik in a 1391 technical treatise by Geoffrey Chaucer (modern Antarctic Pole).
