Nguyễn Huệ, also known as Emperor Quang Trung (born in Bình Định in 1753, died in Phú Xuân on 16 September 1792), was the second emperor of the Tây Sơn Dynasty of Vietnam, reigning from 1788 until 1792. He was also one of the most successful military commanders in Vietnam's history. Nguyễn Huệ and his brothers, together known as the Tây Sơn brothers, were the leaders of the famous Tây Sơn rebellion. As rebels, they conquered Vietnam, overthrowing the imperial Later Lê Dynasty and the two rival feudal houses of the Nguyễn in the south and the Trịnh in the north.
