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 Xinjiang
A 28 year old mixed race woman named Amy whose father was Han and whose mother was Uyghur was interviewed by The Atlantic and she spoke of being estranged from Uyghurs and viewed Uyghur men's appearances negatively. After a Han Chinese man named Xiaohe and a Uyghur woman named Aygul married, the Uyghur women was physically assaulted by her father. A Uyghur family cut off their daughter, a Uyghur woman Ahman who had a Han Chinese husband named Ming. When she had a Han Chinese boyfriend in school her fellow Uyghurs violently assaulted her. Uyghurs are often angered and shun inter-ethnic families with Han men and Uyghur women. These interethnic pairs fled Xinjiang to Beijing.
