Nguyễn Huệ
The Tây Sơn were not content to simply conquer the southern provinces of Quangnam. After a decade of fairly successful fighting in the south against the Nguyễn Lords, Nguyễn Huệ (the leading general of the Tây Sơn and no relation to the Nguyễn ruling family) and his army marched north in 1785. The Royal army under Trịnh Tông vanquished by Nguyễn Huệ. Trịnh Tông committed suicide and the Lê Emperor submitted to the wishes of the victorious Huệ by giving his daughter in marriage to him. Huệ returned south and a few months later, the old emperor died.
