Vietnam History Tây Sơn dynasty, 1788-1802

The Tây Sơn dynasty (Vietnamese: [təj ʂəːn], ; Vietnamese: "Nhà Tây Sơn" or "Triều Tây Sơn", (chữ Hán: 朝西山; Chữ Nôm: 茹西山), officially Đại Việt (Chữ Hán: 大越), was an imperial dynasty of Vietnam. It originated in a revolt led by three peasant brothers with the surname Nguyễn, rebelling against the Lê dynasty,Trịnh lords and Nguyễn lords (no relation). The Tây Sơn would later be succeeded by the Nguyễn dynasty. The Tây Sơn dynasty ended the century-long war between the Trịnh and Nguyễn families, overthrew the Lê dynasty, and united the country for the first time in 200 years. They acknowledged Qing suzerainty and gained recognition from the Qianlong Emperor as the legitimate rulers of Vietnam. Under the most prominent of the Tây Sơn brothers Nguyễn Huệ Vietnam experienced several years of relative peace and prosperity. But Quang Trung died relatively young at the age of 40 and his successor Cảnh Thịnh, aged 9, was unable to prevent civil conflict among the Tây Sơn court which allowed the last Nguyễn lord Nguyễn Ánh to retake the south of Vietnam, extinguish the Tây Sơn and establish the Nguyễn dynasty.
