The Chagatai Khanate was a Mongol ruling khanate controlled by Chagatai Khan, second son of Genghis Khan. Chagatai's ulus, or hereditary territory, consisted of the part of the Mongol Empire which extended from the Ili River (today in eastern Kazakhstan) and Kashgaria (in the western Tarim Basin) to Transoxiana (modern Uzbekistan and Turkmenistan). The exact date that the control of Turfan and other areas of Uighurstan was transferred to another Mongol Dynasty, Chagatai Khanate, is unclear.). Many scholars claim Chagatai Khan (d.1241) inherited Uighurstan from his father, Genghis Khan, as appanage in the early 13th century. By the 1330s, the Chagatayids exercised the full authority over the Uighur Kingdom in Turfan.
