In 1271 Negübei was appointed by Kaidu as head of the Chagatai Khanate. A year after his enthronement, however, he rebelled against his master, possibly in conjunction with the revolts launched by the sons of Alghu and Baraq. Kaidu responded by sending an army against Negübei, and the latter was forced to flee to the east. Soon afterward, he was killed and replaced by Buqa Temür.
