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 Pakistan
Some members of ethnic minorities of China, primarily Muslim Uyghurs and Tajiks from Xinjiang, have historically migrated to and settled in the northern parts of Pakistan. The earliest migrants, numbering in the thousands, came in as traders during the late 19th and early 20th centuries when the area that is Pakistan was still under British rule. Most of these Uyghurs used to have warehouses and residences in towns in the North and in parts of upper Punjab and used to travel between Kashgar and Yarkand and these places, regularly. Others came in the 1940s in fear of communist persecution. A few hundred more fled to Pakistan in the aftermath of a failed uprising in Khotan in 1954. Later waves of migration came in 1963 and again in 1974. Some Pakistani descendants who previously lived in Xinjiang, especially at Kashgar, have also moved back to Pakistan with their Uyghur spouses.
