Ketuyu
Ketuyu was a Khitan military chief, notable for his Ketuyu rebellion. Despite the presence of a khagan, he de facto controlled Khitan politics. His power made the Khitan khagan jealous, and he then defended himself by making a coup in 720, against Li Shaogu. By this action, he incurred Tang dynasty opposition and they sent military campaigns against him, which he defeated several times. He was eventually crushed by repeated Tang campaigns, and was murdered together with Wa khaghan Yaonian Qulie by his subordinate Li Guozhe.
