Li Zicheng, born Li Hongji, also known by his nickname, the Dashing King, was a Chinese peasant rebel leader who helped overthrow the Ming dynasty in April 1644 and ruled over northern China briefly as the Yongchang Emperor of the short-lived Shun dynasty before his death a year later.

The late Ming peasant rebellions were a series of peasant revolts during the last decades of the Ming dynasty lasting from 1628–1644. They were primarily caused by natural disasters in Shaanxi, Shanxi, and Henan. At the same time, the She-An Rebellion and Later Jin incursions forced the Ming government to cut funding for the postal service, which resulted in the mass unemployment of men in the provinces hit hard by natural disasters. Unable to cope with three major crises at the same time, the Ming dynasty collapsed in 1644.
