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.
Uyghurs
Another ethnicity, the Western Yugur of Gansu, have consistently been called by themselves and others the "Yellow Uyghur" ("Sarïq Uyghur"). Some scholars say that the Yugur's culture, language, and religion are closer to the original culture of the original Uyghur Karakorum state than is the culture of the modern Uyghur people of Xinjiang. Linguist and ethnographer S. Robert Ramsey has argued for inclusion of both the Eastern and Western Yugur and the Salar as subgroups of the Uyghur based on similar historical roots for the Yugur and on perceived linguistic similarities for the Salar. These groups are recognized as separate ethnicities, though, by the Chinese government.
