Wu Sangui 吴三桂

Wu Sangui (Chinese:吳三桂; pinyin:Wú Sānguì; Wade–Giles:Wu San-kuei; courtesy name Changbai (長白) or Changbo (長伯); 1612 – 2 October 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", but his revolt was eventually quelled by the Kangxi Emperor of the Qing Dynasty.
