Wu Sangui

Wu Sangui (Chinese: 吳三桂; pinyin: Wú Sānguì; Wade–Giles: Wu San-kuei; style name Changbai (長白) or Changbo (長伯); 1612 – October 2, 1678) was a Chinese military general who was instrumental in the fall of the Ming Dynasty and the establishment of the Qing Dynasty in 1644. Considered by traditional scholars as a traitor to both Ming, and ultimately, Qing, Wu in 1678 declared himself Emperor of China and ruler of the Great Zhou Dynasty, but his revolt was eventually quelled by the Kangxi Emperor of the Qing Dynasty.
