Chagatai language
In the Chagatai Khanate, the Turkic language that was adopted by the Mongol elites became known as the Chagatai language, a descendant of Karluk Turkic. The Chagatai language was the native language of the Timurid dynasty, a Turco-Mongol dynasty who gained power in Central Asia after the decline of the Chagatai Khans. Chagatai is the predecessor of the modern Karluk branch of Turkic languages, which includes Uzbek and Uyghur.
