Uyghurs
Contemporary scholars consider modern Uyghurs to be the descendants of a number of people, including the ancient Uyghurs of Mongolia who arrived at the Tarim Basin after the fall of the Uyghur Khaganate, Iranic Saka tribes, and other Indo-European peoples who inhabited the Tarim Basin before the arrival of the Turkic Uyghurs. DNA analyses indicate that the peoples of central Asia such as the Uyghurs are all mixed Caucasian and East Asian. Uyghur activists identify with the Tarim mummies, remains of an ancient people who inhabited the region, but research into the genetics of ancient Tarim mummies and their links with modern Uyghurs remains problematic, both to Chinese government officials concerned with ethnic separatism, and to Uyghur activists concerned that the research could affect their people's claim of being indigenous to the region.
History of the Uyghur people
The Uighur Idiqut, Barchukh, voluntarily submitted Genghis Khan (r.1206-1227) and was given his daughter, Altani (ᠠᠯᠲᠠᠨ) in 1209. From the 1260s onwards, they were directly controlled by the Yuan Dynasty of the Great Khagan Kublai (r.1260-1294). Starting from the 1270s, Mongol princes, Qaidu and Duwa, from Central Asia repeatedly launched raids into Uighurstan to take the control from the Yuan. Most of the Uighurs including the ruling dynasty fled to Gansu (under Yuan Dynasty) due to the conflict between the Mongols. The Uighur troops served the Mongol war machine in Central Asia, China and the Middle East. Because they were one of the many highly developed nations under the Mongols, the Uighurs held high-positions at the Mongol court. Tata-tunga was the first scribe of Genghis Khan and mastermind behind the Uighur-Mongolian script that the Mongols used till now. The founder of the Eretna (1335–1381) in Anatolia was an Uighur commander of the Ilkhanate.
