The Jiashen Incident (simplified Chinese: 甲申之变; traditional Chinese: 甲申之變), also known as the Battle of Beijing, took place in 1644 in the areas surrounding Beijing, and was fought between forces of the incumbent Ming dynasty and the Shun dynasty founded by peasant rebel leader Li Zicheng. It eventually resulted in the collapse of the Ming dynasty. Remnants of the Ming imperial family, whose regime is known as the Southern Ming dynasty in historiography, would continue to rule parts of southern China until 1662.
