Qazan

Qazan (died 1346), son of the Chagatayid prince Yasa'ur, was khan of the Chagatai ulus from about 1343. He moved to curb the Turkic nobility of Transoxiana, who rallied behind the Qara'unas amir Qazaghan. In a battle of 1345 north of the Iron Gates, Qazan routed Qazaghan and put out one of his eyes, but then withdrew to winter at Qarshi instead of pursuing.

Qazaghan rebuilt his forces, counterattacked in 1346 and killed Qazan. With his death the Chagatai khans lost real power in Transoxiana and the ulus split in two.
