Tughlugh Timur
In the east, Tughlugh Timur (1347–1363), a Chaghataite adventurer, defeated the nomadic Mongols and converted to Islam. During his rein (until 1363), the Moghuls converted to Islam and slowly Turkified. In 1360, and again in 1361, Timur invaded the western half in the hope that he could reunify the khanate. At their height, the Chaghataite domains extended from the Irtysh River in Siberia down to Ghazni in Afghanistan, and from Transoxiana to the Tarim Basin.
