Wu Sangui
Wu Sangui (courtesy name Changbai (長白) or Changbo (長伯); 1612 – 2 October 1678) was a Chinese military leader who played an instrumental role in the fall of the Ming dynasty and the establishment of the Qing dynasty in its place.
In 1644, after the rebel leader Li Zicheng killed his father, the Ming general Wu Xiang, Wu Sangui allied with the Qing Prince Dorgon and allowed the Manchu army passage through the Shanhaiguan to suppress Li's rebellion.
For his efforts in establishing the Qing dynasty, he was given a large fiefdom consisting of Yunnan and, later, Guizhou provinces, as well as the noble title "Prince
Who Pacifies the West".
In 1674, instead of retiring from service, Wu decided to rebel against the Qing.
In 1678, Wu declared himself the Emperor of China and the ruler of the Great Zhou, only to die within months.
For a time, his grandson Wu Shifan succeeded him; however, the Kangxi Emperor of the Qing Dynasty eventually quelled the revolt.
Wu Sangui is considered by traditional scholars as having been a traitor to both the Ming and the Qing dynasties.
