Tughlugh Timur
Tughlugh Timur (1347–1363) was thereby made the head of a tribal confederacy that governed the Tarim Basin and the steppe area of Moghulistan (named after the Moghuls). His reign was contemporaneous with the series of puppet khans that ruled in Transoxiana, meaning that there were now effectively two khanates headed by Chagatayids: one in the west, centered in Transoxiana, and one in the east, centered in Moghulistan. Unlike the khans in the west, however, Tughlugh Timur was a strong ruler who converted to Islam (1354) and sought to reduce the power of the Dughlats. In 1360 he took advantage of a breakdown of order in Transoxiana and his legitimacy as descendant of Chagatai Khan to invade the region and take control of it, thereby temporarily reuniting the two khanates. Despite invading a second time in 1361 and appointing his son Ilyas Khoja as governor of Transoxiana, however, Tughlugh Timur was unable to keep a lasting hold on the region, and the Moghuls were ultimately expelled by Amir Husayn and Timur, who then fought amongst themselves for control of Transoxiana.
