Lê Chiêu Thống
After the capture of Phú Xuân (modern Huế), Nguyễn Hữu Chỉnh, a traitor of Trịnh's general, encouraged Nguyễn Huệ to overthrow the Trịnh lord. Huệ took his advice, marched north and captured Thăng Long (modern Hanoi). In 1788, Lê Chiêu Thống was installed the new Lê emperor by Huệ. Huệ then retreated to Phú Xuân.
