Ashina Buzhen

Ashina Buzhen (Chinese: 阿史那步真) was a member of the ruling caste of the Western Turks. He was appointed khagan by Emperor Gaozong of the Tang dynasty after the conquest of the Western Turks. His fierce rivalry with his cousin, Ashina Mishe, was instrumental in driving the Western Turks away from the Tang and into allegiance with the Tibetan Empire.
