Shun dynasty

The Shun dynasty, officially the Great Shun, also known as Li Shun, was a short-lived dynasty of China that existed during the Ming–Qing transition. The dynasty was founded in Xi'an on 8 February 1644, the first day of the lunar year, by Li Zicheng, the leader of a large peasant rebellion, by proclaiming himself "emperor" (皇帝) instead of the title "king" (王) before founding the dynasty.

The capture of Beijing by the Shun forces in April 1644 marked the end of the Ming dynasty, but Li Zicheng failed to solidify his political and military control, and in late May 1644 he was defeated at the Battle of Shanhai Pass by the joint forces of Ming general Wu Sangui (who had defected to the Qing dynasty), with Manchu prince Dorgon. When he fled back to Beijing in early June, Li finally proclaimed himself the Yongchang Emperor of the Great Shun and left the capital the next day after setting the palace ablaze and ransacking the government offices. He may have intended to resume his Imperial claims later on by proclaiming his accession in the Forbidden City. After the death of the emperor, Shun remnants joined with the Southern Ming in Nanjing, while continuing to refer to Li as their "deceased emperor". The Shun dynasty weakened dramatically after the death of Li Zicheng in 1645. The successors, his brother Li Zijing and nephew Li Guo, could not fight back and the dynasty ended in 1649 when Li Guo died in Nanning, Guangxi.

After the Shun was created, Li Zicheng ordered the soldiers to kill the Ming remnants still existing in Beijing, resulting in strong rebellions from the forces of the Southern Ming. With the Shun ministers constantly fighting for power, the dynasty effectively lasted less than a year.
