Trịnh Tùng
In 1592, the new Mạc leader was Mạc Kinh Chi. He managed to assemble a large army which defeated the army of Trịnh Tùng but a year later, he and his army were wiped out by a new Trịnh army under Trịnh Tùng. Mạc Kinh Cung ruled for more than twenty years (1593–1616). Based out of Van Ninh (Quảng Ninh Province) the Mạc army staged many attacks against the Trịnh. The Trịnh requested and received aid from the Nguyễn and the joint army (with Nguyễn Hoàng) defeated the Mạc.
