century they identified themselves by different names to different peoples and in response to different inquiries: they called themselves Sarts in front of Kazakhs and Kyrgyz while they called themselves "Chantou" if asked about their identity after first identifying as a Muslim. The term "Chantou" (, meaning "Rag head" or "Turban Head") was used to refer to the Turkic Muslims of Xinjiang, including by Hui (Tungan) people. These groups of peoples often identify themselves by their originating oasis instead of an ethnicity; for example those from Kashgar may refer to themselves as Kashgarliq or Kashgari, while those from Hotan identity themselves as "Hotani". Other Central Asians once called all the inhabitants of Xinjiang's Southern oases Kashgari, a term still used in some regions of Pakistan. The Turkic people also used "Musulman", which means "Muslim", to describe themselves. 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 for their identity; various native names Altishahris used for identify were Altishahrlik (Altishahr person), yerlik (local), Turki and Musulmān (Muslim); the term Musulmān in this situation did not signify religious connotations, because the Altishahris exclude other Muslim peoples like the Kirghiz while identifying themselves as Musulmān. Dr. Laura J Newby says the sedentary Altishahri Turkic people considered themselves separate from other Turkic Muslims since at least the 19th century. The name "Uyghur" reappeared after the Soviet Union took the 9th-century ethnonym from the Uyghur Khaganate, then reapplied it to all non-nomadic Turkic Muslims of Xinjiang. It followed western European orientalists like Julius Klaproth in the 19th century who revived the name and spread the use of the term to local Turkic intellectuals and a 19th-century proposal from Russian historians that modern-day Uyghurs were descended from the Kingdom of Qocho and Kara-Khanid Khanate formed after the dissolution of the Uyghur Khaganate. Historians generally agree that the adoption of the term "Uyghur" is based
