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 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.
