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.
Uyghur nationalism
Those that use the term "Uyghurstan" tend to envision a state for the Uyghur people. Those groups that adopt this terminology tended to be allied with the Soviet Union while it still existed (Indeed, Russia incited and aided the rebellion in attempt to annex these regions in the future). Since then some of the leaders of these groups have remained in Russia, Kazakhstan or Kyrgyzstan, or have emigrated to Europe and North America. It is worth noting that none of these identities are exclusive. Some groups support more than one such orientation. It is common to support both an Islamic and Turkic orientation for Xinjiang, for example, the founders of independent Republic in Kashgar in 1933 used names "Turkic Islamic Republic of East Turkestan" and "Eastern Turkestan Republic" the same time.
