Trịnh Kiểm
The Nguyễn-Trịnh alliance, now under the command of Trịnh Kiểm, continued to fight the Mạc. A new king was enthroned as Lê Trung Tông in 1548, then another Lê king, Lê Anh Tông, was enthroned in 1556. In 1558 the eldest son of Nguyễn Kim, Nguyễn Hoàng, was sent to the south to take control over the recently conquered province of Quảng Nam. By 1665, the Royal (Trịnh) army had captured all provinces south of the Red River and were threatening Hanoi.
