In 1573, Anh Tông saw that Trịnh Tùng was autocratic, so he and four great princes left the palace of Vạn Lại and fled to Nghệ An.
During the reign of Thế Tông, Trịnh Tùng took full control of the military and continued to wage war with the Mạc in Đông Kinh.
After many great campaigns, in 1592 Trịnh Tùng defeated the Mạc army, regained Đông Kinh and brought Thế Tông back to the old capital.
Therefore, the national history of Đại Việt was compiled by Trịnh lords and considered Lê Thế Tông to be the king who was instrumental in restoring the inheritance of the Later Le dynasty.
In fact, although the Lê dynasty was re-established, the real power fell into Trịnh Tùng's hands, leaving the king with only vanity.
