Wang Shichong

Wang Shichong, a Sui general, staged a coup in Luoyang, killing the Sui regent and declaring himself emperor of the short-lived Zheng dynasty. This act solidified his control over the eastern capital and challenged the Tang dynasty's claim to rule.

Wang Shichong's forces were decisively defeated by Li Shimin's Tang army at Hulao Pass. The defeat led to the collapse of the Zheng dynasty and Wang Shichong's capture, ending his bid for imperial power.

After his capture at Hulao, Wang Shichong was executed by the Tang dynasty. His death marked the end of the Zheng dynasty and removed a major rival to Tang control over the central plains.
