Nguyễn Huệ
Having vanquished the Nguyễn for the time being, Nguyễn Huệ decided to destroy the power of the Trịnh lords. He marched to the north at the head of a large army in 1786, and after a short campaign, defeated the Trịnh army successfully. The Trịnh were also unpopular and the Tây Sơn army seemed invincible. The Trịnh lord fled north into China. Nguyễn Huệ later married princess Lê Ngọc Hân, the daughter of the nominal later Lê Emperor, Lê Hiển Tông.
