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 language
The historical term "Uyghur" was appropriated for the language that had been known as Eastern Turki by government officials in the Soviet Union in 1922 and in Xinjiang in 1934. Sergey Malov was behind the idea of renaming Turki to Uyghurs. The use of the term Uyghur has led to anachronisms when describing the history of the people. In one of his books the term Uyghur was deliberately not used by James Millward. The name Khāqāniyya was given to the Qarluks who inhabited Kāshghar and Bālāsāghūn, the inhabitants were not Uighur, but their language has been retroactively labelled as Uighur by scholars. The Qarakhanids called their own language the "Turk" or "Kashgar" language, and did not use Uighur to describe their own language, Uighur was used to describe the language of non-Muslims but Chinese scholars have anachronistically called a Qarakhanid work written by Kashgari as "Uighur". The name ""Altishahri-Jungharian Uyghur"" was used by the Soviet educated Uyghur Qadir Haji in 1927.
