Ashina Helu
Ashina Zhong, the brother of She'er, also served as a Turkic general of the Tang Dynasty, and was a participant in a military performance hosted by Emperor Gaozong in 655. Another Turkic member of the Ashina clan, Ashina Helu, briefly served as a commander of the Tang army in Gansu before his rise as a kaghan of the Western Turkic Khaganate. During his reign, the Turkic tribes were unified under a single leader. Emperor Gaozong, Taizong's successor, dispatched a military expedition in 657 against Helu, who had been raiding Tang settlements. The campaign was led by the general Su Dingfang and the Turkic commanders Ashina Mishe and Ashina Buzhen, who were opposed to Helu. Helu was defeated and captured by the Tang forces, and the territories annexed from the Western Turks were placed under Tang governance through the Anxi Protectorate.
