Qazan Khan ibn Yasaur
These measures provoked the anger of the nobility, who threw their support behind the Qara'unas Amir Qazaghan.The two went to war in 1345; Qazan defeated Qazaghan in a battle north of the Iron Gates.Defeated and wounded, Qazaghan withdrew, but rather than giving pursuit Qazan decided to spend the winter at his palace at Qarshi, allowing Qazaghan to rebuild his forces.[2] Qazan's death marked the end of the effective power of the house of Chagatai within Transoxiana (except for a brief period from 1360 until 1363); the amirs seized control of the ulus and the khans ruled in name only.[3] The next khan, Danishmendji, was a puppet of Qazaghan, who became the effective leader of the ulus.
