Shun dynasty

The Shun dynasty (simplified Chinese: 顺朝; traditional Chinese: 順朝; pinyin: "Shùn cháo"), officially the Great Shun (simplified Chinese: 大顺; traditional Chinese: 大順; pinyin: "Dà Shùn"), was a short-lived Chinese dynasty 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. The founder was Li Zicheng, the leader of a large peasant rebellion. He proclaimed himself "emperor" (皇帝) instead of the title "king" (王) before founding the dynasty.
