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.
Dungan Revolt (1862–77)
The ethnic group now known as Uyghur people was not known by that name before the 20th century. The Uzbeks of Yaqub Beg were called "Andijanis" or "Kokandis", while the Uyghurs in the Tarim Basin were known as "Turki". Uyghur immigrants from the Tarim Basin to Ili were called "Taranchi". The modern name "Uyghur" was assigned to this ethnic group by the Soviet Union in 1921 at a conference in Tashkent, with the name "Uyghur" taken from the old Uyghur Khaganate. As a result, sources from the period of the Dungan revolt make no mentions of Uyghurs.
