paragraph_text: Kublai Khan did not conquer the Song dynasty in South China until 1279, so Tibet was a component of the early Mongol Empire before it was combined into one of its descendant empires with the whole of China under the Yuan dynasty (1271–1368). Van Praag writes that this conquest "marked the end of independent China," which was then incorporated into the Yuan dynasty that ruled China, Tibet, Mongolia, Korea, parts of Siberia and Upper Burma. Morris Rossabi, a professor of Asian history at Queens College, City University of New York, writes that "Khubilai wished to be perceived both as the legitimate Khan of Khans of the Mongols and as the Emperor of China. Though he had, by the early 1260s, become closely identified with China, he still, for a time, claimed universal rule", and yet "despite his successes in China and Korea, Khubilai was unable to have himself accepted as the Great Khan". Thus, with such limited acceptance of his position as Great Khan, Kublai Khan increasingly became identified with China and sought support as Emperor of China.

paragraph_text: Timber was the chief building material during the Han dynasty; it was used to build palace halls, multi-story residential towers and halls and single-story houses. Because wood decays rapidly, the only remaining evidence of Han wooden architecture is a collection of scattered ceramic roof tiles. The oldest surviving wooden halls in China date to the Tang dynasty (618–907 AD). Architectural historian Robert L. Thorp points out the scarcity of Han-era archaeological remains, and claims that often unreliable Han-era literary and artistic sources are used by historians for clues about lost Han architecture.

paragraph_text: Emperor Fei of Jin (; 342 – November 23, 386), personal name Sima Yi (司馬奕), courtesy name Yanling (延齡), was an emperor of the Eastern Jin Dynasty (265-420) in China. He was the younger brother (from the same mother) of Emperor Ai and later deposed by military leader Huan Wen. The title that he is normally referred to, "Emperor Fei", is not a posthumous name as is usually the case with imperial common titles, but rather signified that he was deposed (with "Fei" (廢) meaning "depose"). He is also commonly known by the title he was given after his removal, Duke of Haixi (海西公).

paragraph_text: The city of Beijing has a long and rich history that dates back over 3,000 years. Prior to the unification of China by the First Emperor in 221 BC, Beijing had been for centuries the capital of the ancient states of Ji and Yan. During the first millennia of imperial rule, Beijing was a provincial city in northern China. Its stature grew in the 10th to the 13th centuries when the nomadic Khitan and forest - dwelling Jurchen peoples from beyond the Great Wall expanded southward and made the city a capital of their dynasties, the Liao and Jin. When Kublai Khan made Dadu the capital of the Mongol - led Yuan dynasty (1279 -- 1368), all of China was ruled from Beijing for the first time. From 1279 onward, with the exception of two interludes from 1368 to 1420 and 1928 to 1949, Beijing would remain as China's capital, serving as the seat of power for the Ming dynasty (1421 -- 1644), the Manchu - led Qing dynasty (1644 -- 1912), the early Republic of China (1912 -- 1928) and now the People's Republic of China (1949 -- present).

paragraph_text: Qin Shi Huang (Chinese: 秦始皇; literally: ``First Emperor of Qin '', pronunciation (help info); 18 February 259 BC -- 10 September 210 BC) was the founder of the Qin dynasty and was the first emperor of a unified China. He was born Ying Zheng (嬴政) or Zhao Zheng (趙政), a prince of the state of Qin. He became Zheng, the King of Qin (秦王政) when he was thirteen, then China's first emperor when he was 38 after the Qin had conquered all of the other Warring States and unified all of China in 221 BC. Rather than maintain the title of`` king'' (王 wáng) borne by the previous Shang and Zhou rulers, he ruled as the First Emperor (始皇帝) of the Qin dynasty from 220 to 210 BC. His self - invented title ``emperor ''(皇帝 huángdì), as indicated by his use of the word`` First'', would continue to be borne by Chinese rulers for the next two millennia.

paragraph_text: In 1368, a Han Chinese revolt known as the Red Turban Rebellion toppled the Mongol Yuan dynasty in China. Zhu Yuanzhang then established the Ming dynasty, ruling as the Hongwu Emperor (r. 1368–1398). It is not clear how much the early Ming court understood the civil war going on in Tibet between rival religious sects, but the first emperor was anxious to avoid the same trouble that Tibet had caused for the Tang dynasty. Instead of recognizing the Phagmodru ruler, the Hongwu Emperor sided with the Karmapa of the nearer Kham region and southeastern Tibet, sending envoys out in the winter of 1372–1373 to ask the Yuan officeholders to renew their titles for the new Ming court.

paragraph_text: The Qing dynasty (1644–1911) was founded after the fall of the Ming, the last Han Chinese dynasty, by the Manchus. The Manchus were formerly known as the Jurchens. When Beijing was captured by Li Zicheng's peasant rebels in 1644, the Chongzhen Emperor, the last Ming emperor, committed suicide. The Manchus then allied with former Ming general Wu Sangui and seized control of Beijing, which became the new capital of the Qing dynasty. The Mancus adopted the Confucian norms of traditional Chinese government in their rule of China proper. Schoppa, the editor of The Columbia Guide to Modern Chinese History argues, "A date around 1780 as the beginning of modern China is thus closer to what we know today as historical 'reality'. It also allows us to have a better baseline to understand the precipitous decline of the Chinese polity in the nineteenth and twentieth centuries."

paragraph_text: Andronikos V Palaiologos was the only known son of Emperor John VII Palaiologos and Irene Gattilusio, daughter of Francesco II Gattilusio. At the time of his birth John VII was Regent of the Byzantine Empire for his uncle Manuel II Palaiologos. At an unknown date, probably after his father settled in Thessalonica, Andronikos V was proclaimed nominal co-emperor, probably by 1403/1404. He predeceased his father, dying probably in 1407 and with that ended the furthest line of descent of Byzantine (co-)emperors possible from his dynasty's founder, Michael VIII.

paragraph_text: The Yuan dynasty (; ), officially the Great Yuan (; Middle Mongolian: , , literally "Great Yuan State"), was the empire or ruling dynasty of China established by Kublai Khan, leader of the Mongolian Borjigin clan. It followed the Song dynasty and preceded the Ming dynasty. Although the Mongols had ruled territories including modern-day North China for decades, it was not until 1271 that Kublai Khan officially proclaimed the dynasty in the traditional Chinese style, and the conquest was not complete until 1279 when the Southern Song dynasty was defeated in the Battle of Yamen. His realm was, by this point, isolated from the other Mongol khanates and controlled most of modern-day China and its surrounding areas, including modern Mongolia. It was the first non-Han Chinese dynasty to rule all of China and lasted until 1368 when the Ming dynasty defeated the Yuan forces. Following that, the rebuked Genghisid rulers retreated to their Mongolian homeland and continued to rule as the Northern Yuan dynasty. Some of the Mongolian Emperors of the Yuan mastered the Chinese language, while others only used their native language (i.e. Mongolian) and the 'Phags-pa script.
