to subdue Sarai, the traditional capital of the Golden Horde. Offended and wary of any opposition to his authority, Urus had Tuy Khwāja executed. The young Tokhtamysh fled, then submitted to his father's murderer, and was forgiven on account of his youth. In 1373, while Urus was asserting himself at Sarai, Tokhtamysh gathered a group of Urus' opponents and attempted to make himself khan in Sighnaq. Urus immediately advanced against them, and Tokhtamysh fled, only to return, submit, and be forgiven again. When Urus took over Sarai in 1375, Tokhtamysh took the opportunity to flee again. He sought refuge at the court of Timur (Tamerlane), where he arrived in 1376. Winning his favor and support, Tokhtamysh installed himself at Otrar and Sayram on the Syr Darya in 1376, raiding into Urus Khan's territory. Urus' son Qutluq Buqa attacked and defeated Tokhtamysh, although he himself suffered a fatal wound. Tokhtamysh fled to Timur once more, and returned with an army to fight his enemies. However, he was defeated again, this time by Urus' son Toqtaqiya. Wounded, Tokhtamysh escaped by swimming across the Syr Darya and once more went to Timur's court, at Bukhara. Here he discovered that Urus was advancing in his pursuit, and soon Urus' envoys arrived, demanding Tokhtamysh's extradition. Timur refused to do so and gathered his own forces to oppose Urus. Following a three-month standoff in the winter of 1376–1377, Urus returned home, while Timur's forces succeeded in taking Otrar. Learning of Urus' death, Timur declared Tokhtamysh the new khan, and returned to his own capital, Samarkand. Rise to power Urus was succeeded as khan by his son Toqtaqiya, who died after two months, and then by his other son, Tīmūr Malik. As before, Tokhtamysh had little luck fighting against a son of Urus, and he was easily defeated by Tīmūr Malik. Tokhtamysh fled to Timur's court once again. Hearing that Tīmūr Malik spends his time in drinking and pleasures and ignores affairs of importance, and that the exasperated people desire Tokhtamysh to rule them, Timur sent his forces to Sawran and Otrar, which surrendered. Advancing on Sighnaq, they defeated the enemy at Qara-Tal, and captured and executed Tīmūr Malik, betrayed by his own emirs, in 1379. Tokhtamysh was now installed as khan in Sighnaq, and he spent the rest of the year establishing his authority and harnessing his resources for his next target, Sarai. In 1380, Tokhtamysh
