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.
History of the Uyghur people
Some Uyghur nationalist claimed that they were descended from the Tocharians. Discovered well-preserved Tarim mummies of a people European in appearance indicates the migration of an Indo-European people into the Tarim area at the beginning of the Bronze age around 2,000 BCE. These people probably spoke Tocharian, and were suggested by some to be the Yuezhi mentioned in ancient Chinese text and who later founded the Kushan Empire. The Uyghur claim is based partly on a word, which they argued to be Uyghur, found in written scripts associated with these mummies, although other linguists suggested that it was a Sogdian word later absorbed into Uyghur. Later migrations brought peoples from the west and northwest to the Xinjiang area, probably speakers of various Iranian languages such as the Saka tribes. Other ancient people in the region mentioned in ancient Chinese texts include the Xiongnu who fought for supremacy in the region against the Chinese for several hundred years. Some Uyghur nationalists claimed descent from the Xiongnu (as well as being related to the White Huns), however this view is contested by modern Chinese scholars. This Xiongnu claim originated from various Chinese historical texts; for example, according to Chinese history "Weishu", the founder of the Uyghurs was descended from a Xiongnu ruler.
