  By about 1360, Timur had gained prominence as a military leader whose troops were mostly Turkic tribesmen of the region. He took part in campaigns in Transoxiana with the Khan of the Chagatai Khanate. Allying himself both in cause and by family connection with Qazaghan, the dethroner and destroyer of Volga Bulgaria, he invaded Khorasan at the head of a thousand horsemen. This was the second military expedition that he led, and its success led to further operations, among them the subjugation of Khwarazm and Urgench.
  
  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 Barlas. Tughlugh then attempted to set his son Ilyas Khoja over Transoxania, but Timur repelled this invasion with a smaller force.
