Gao Kaidao

Gao Kaidao, also known as Li Kaidao, was a Chinese agrarian rebel leader who opposed the Sui dynasty during the late reign of Emperor Yang. He established control over the Huairong region and declared himself Prince of Yan, forming an alliance with the Eastern Turkic Khaganate. In 620, he briefly submitted to Emperor Gaozu of Tang, receiving the imperial surname Li, but he rebelled against the Tang dynasty in 621 to regain independence. In 624, facing a coup led by his general Zhang Jinshu, Gao Kaidao committed suicide.
