Tughlugh Timur
Following Qazaghan's murder, disputes arose among the many claimants to sovereign power. Tughlugh Timur of Kashgar, the Khan of the Eastern Chagatai Khanate, another descendant of Genghis Khan, invaded, interrupting this infighting. Timur was sent to negotiate with the invader but joined with him instead and was rewarded with Transoxania. At about this time, his father died and Timur also became chief of the Berlas. Tughlugh then attempted to set his son Ilyas Khoja over Transoxania, but Timur repelled this invasion with a smaller force.
