Mạc Đăng Dung
The Lê dynasty was overthrown by its general named Mạc Đăng Dung in 1527. He killed the Lê emperor and proclaimed himself emperor, starting the Mạc dynasty. After defeating many revolutions for two years, Mạc Đăng Dung adopted the Trần dynasty's practice and ceded the throne to his son, Mạc Đăng Doanh, and he became Thái Thượng Hoàng.
