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 Kazakhstan
Uyghurs in Kazakhstan can be roughly divided into three groups based on the time of their ancestors' migration. The earliest, the "yärlik" ("locals"), are those who have been in the country the longest. They came to various areas of Kazakhstan, especially Semirechie, in the late 19th and early 20th century. Most of the more than 200,000 Uyghurs in Kazakhstan trace their roots to the migrations during the 1950s and 1960s. They tend to refer to themselves as "kegänlär", literally "newcomers". Others used to call them "kitailik" ("Chinese"), but now the more commonly used term has become "köchäp kegän"; "kitailik" instead has come to refer to the latest Uyghur newcomers, those who have arrived since the 1990s (also referred to as "wätändin", or "people from the homeland").
