Trịnh Tùng
In 1592, Đông Đô (Hanoi) was captured the last time by the Trịnh army under Trịnh Tùng, and the Mạc Emperor was executed. The next year, Nguyễn Hoàng came north with an army and money to help defeat the remainder of the Mạc forces, but soon afterwards Nguyễn Hoàng refused to obey the orders coming from the new court in Hanoi.
