Trịnh Doanh took over from his brother, Trịnh Giang, who, through financial mismanagement and bad behavior, provoked a wave of revolts against his rule. This was a time of increasing peasant revolts in both the north and the south under the Nguyễn Lords. In the north, some of the revolts were apparently led by members of the royal Lê family.
Despite the many revolts, Trịnh Doanh defeated them all and passed the rule of Vietnam to his son, Trịnh Sâm.
As far as the Lê Dynasty was concerned, there was just one king, Lê Hien Tông (1740–1786), who occupied the royal throne in Hanoi.
