阿史那賀魯
Ashina Helu, a former Tang general in Gansu, fled west and declared himself qaghan of the Western Turks, unifying the Turkic tribes under a single khaganate. Helu invaded the kingdoms of the Tarim Basin and led frequent raids against bordering Tang cities. Emperor Gaozong sent an army led by Su Dingfang to defeat the Western Turks. The Turkic commanders Ashina Misha and Ashina Buzhen, rivals of Helu, led the side divisions.
