Uyghurs
Rian Thum explored the concepts of identity among the ancestors of the modern Uyghurs in Altishahr (the native Uyghur name for eastern Turkestan or southern Xinjiang) before the adoption of the name "Uyghur" in the 1930s, referring to them by the name "Altishahri" in his article "Modular History: Identity Maintenance before Uyghur Nationalism". Thum indicated that Altishahri Turkis did have a sense that they were a distinctive group separate from the Turkic Andijanis to their west, the nomadic Turkic Kirghiz, the nomadic Mongol Qalmaq, and the Han Chinese Khitay before they became known as Uyghurs. There was no single name used by them to refer to themselves, the various native names Altishahris used to refer to themselves were Altishahrlik (Altishahr person), yerlik (local), Turki, and Musulmān (Muslim), the term Musulmān in this situation did not signify religious connotations, because the Altishahris would exclude other Muslim peoples like the Kirghiz when referring to themselves as Musulmān. Dr. Laura J Newby has also noted that the sedentary Altishahri Turkic people felt themselves as a separate group from other Turkic Muslims since at least the 19th century.
History of the Uyghur people
In the eastern portion of the Chagatai Khanate, known as the Eastern Chagatai Khanate to Chinese historians and as Moghulistan to Russian historians, the culture of the Karakhanids dominated the largely Muslim state, and the Buddhist populations of the former Karakhoja Idikut-ate largely converted to the Muslim faith. All Chagatai-speaking Muslims, regardless whether they lived in Turpan or Kashgar, became known by their occupations as Moghols (ruling class), Sarts (merchants and townspeople) and Taranchis (farmers). This triple division of classes among the same Muslim Turkic folk also existed in Transoxiana, regardless whether they were under Timurid or Chagatay.
