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.
Turkmens
The modern Turkmen people descend, at least in part, from the Oghuz Turks of Transoxiana, the western portion of Turkestan, a region that largely corresponds to much of Central Asia as far east as Xinjiang. Oghuz tribes had moved westward from the Altay mountains in the 7th century AD, through the Siberian steppes, and settled in this region. They also penetrated as far west as the Volga basin and the Balkans. These early Turkmens are believed to have mixed with native Sogdian peoples and lived as pastoral nomads until the Russian invasion of the 19th century.
