Berdi Beg was killed in a coup by his brother Qulpa in 1359. Qulpa's two sons were Christians and bore the Russian names, Michael and Ivan, which outraged the Muslim populace of the Golden Horde. In 1360, Qulpa's brother Nawruz Beg revolted against the khan and killed him and his sons. In 1361, a descendant of Shiban (5th son of Jochi), was invited by some grandees to seize the throne. Khidr rebelled against Nawruz, whose own lieutenant betrayed him and handed him over to be executed. Khidr was slain by his own son, Timur Khwaja, in the same year. Timur Khwaja reigned for only five weeks before descendants of Öz Beg Khan seized power.
