Background
His parentage is uncertain as he was either son of Bagha Qaghan or Ishbara Qaghan. He was a subordinate khagan under Tulan Qaghan with title of Tolis Qaghan, ruling eastern tribes. He sent an ambassador to Sui dynasty in 597, requesting to marry to a Chinese princess. Pei Jusaw this as opportunity and told him to kill Tulan Qaghan's Zhouorigin khatun Princess Qianjin. Princess was murdered and emperor fulfilled his promise, sending Princess Anyi to marry him. However, Tolis' ambitious behaviour caused outrage to khagan.
