A number of Mongol and Turkic peoples occupied the river banks for many centuries. In 657, Tang Dynasty general Su Dingfang defeated Ashina Helu, qaghan of the Western Turkic Khaganate, at the Battle of Irtysh River, ending the Tang campaign against the Western Turks. Helu's defeat ended the Khaganate, strengthened Tang control of Xinjiang, and led to Tang suzerainty over the western Turks.
