History of the Uyghur people
The history of the Uyghur people, as with the ethnic origin of the people, is an issue 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 Turgun 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. Chinese historians however generally traced the origin of the Uyghurs to the Tiele, some to the Dingling as well as other people mentioned in ancient Chinese texts such as the Guifang. Official Chinese view asserts the Uyghurs to be of Tiele origin, 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 that they claimed were there since the Han Dynasty. Many modern Western scholars however do not consider the modern Uyghurs to be of direct linear descent from the old Uyghur Khaganate of Mongolia, rather they are descendants of a number of people, of which the ancient Uyghurs are but one.
Uyghurs in Beijing
During the Tang dynasty, the ancient Uyghur Kingdom and the Tang government had close relations and large numbers of ancient Uyghurs of Mongolia including merchants and soldiers migrated to Youzhou (modern Beijing). The Tang governor of Youzhou, Zhu Tao, who rebelled against the Tang dynasty in 783, had a Uyghur wife and 3,000 Uyghur cavalry under his command. After the Uyghur Kingdom was conquered by the Yenisei Kirghiz in 840, many Uyghurs fled south to Tang China and some 30,000 settled in Youzhou. In the Liao dynasty, Youzhou became the Southern Capital of the Liao and Uyghurs merchants lived in a part of the city known as the "Weiwuerying" or the "Uyghur Camp."
