Uyghurs
The history of the Uyghur people, as with the ethnic origin of the people, is a matter of contention between Uyghur nationalists and the Chinese authority. Uyghur historians viewed the Uyghurs as the original inhabitants of Xinjiang with a long history. Uyghur politician and historian Muhemmed Imin Bughra wrote in his book "A History of East Turkestan", stressing the Turkic aspects of his people, that the Turks have a 9000-year history, while historian Turghun Almas incorporated discoveries of Tarim mummies to conclude that Uyghurs have over 6400 years of history, and the World Uyghur Congress claimed a 4,000-year history in East Turkestan. However, the official Chinese view asserts that the Uyghurs in Xinjiang originated from the Tiele tribes and only became the main social and political force in Xinjiang during the ninth century when they migrated to Xinjiang from Mongolia after the collapse of the Uyghur Khaganate, replacing the Han Chinese they claimed were there since the Han Dynasty. Many contemporary Western scholars, however, do not consider the modern Uyghurs to be of direct linear descent from the old Uyghur Khaganate of Mongolia. Rather, they consider them to be descendants of a number of peoples, one of them the ancient Uyghurs.
Uyghurs in Beijing
After Genghis Khan captured Beijing from the Jin dynasty in 1215, Uyghur noble families serving the Mongol court were sent to administer the city, then renamed Yanjing. These Uyghur nobles were from the Qocho Kingdom, which was formed in the Tarim Basin in 855 and submitted to the Mongols in 1209. Among the Uyghurs who came to Yanjing was Buluhaya, who was a lieutenant of Genghis Khan and given the rank of financial manager. He built a large estate outside the city along the Gaoliang River and moved his mother there. The settlement became known as the "Weiwuercun" or the "Uyghur Village." After Buluhaya's death, he was posthumously honored by Külüg Khan as the Duke of Wei. It is believed that "Weigongcun" or the Village of the Duke of Wei, was so-named because of Buluhaya (布鲁海牙).
