Gao Kaidao

Gao Kaidao, at one point known as Li Kaidao (李開道), was an agrarian rebel leader who rose against the Sui dynasty at the end of Emperor Yang's reign. He occupied the region centering Huairong and claimed the title of Prince of Yan, in alliance with the Eastern Turkic Khaganate. In 620, he briefly submitted to Emperor Gaozu of Tang and was bestowed the imperial surname of Li, but in 621 he rebelled against Tang and reasserted independence. In 624, his general Zhang Jinshu (張金樹) started a coup and he, realizing that the coup was about to succeed, committed suicide.
