莫登庸
The armies of Nguyễn Kim and Trịnh Kiểm captured the summer palace and crowned their own puppet Lê emperor, Lê Trang Tông, in 1533 (in Vietnamese histories this date marks the beginning of the second half of the Later Lê dynasty). The war raged back and forth with the Nguyễn–Trịnh army on one side and the Mạc on the other until an official Ming delegation determined that Mạc Đăng Dung's usurpation of power was not justified. In 1537, a very large Ming army was sent to restore the Lê family. Although Mạc Đăng Dung managed to negotiate his way out of defeat by the Ming, he had to officially recognize the Lê emperor and the Nguyễn–Trịnh rule over the southern part of Vietnam. But the Nguyễn–Trịnh alliance did not accept the Mạc rule over the northern half of the country and so the war continued. In 1541, Mạc Đăng Dung died.
