鄭松
Trịnh Tùng was reputed to be from the first generation of the Trịnh lords who ruled Vietnam from 1545 to 1789, however, since he was so young when the family first came to power, Trịnh Tùng theoretically belonged to the second generation. The Trịnh family wielded the military power of the country and took turns as regents to the figurehead Lê kings who nominally reigned over the country. Trịnh Kiểm, Tùng's father, was given the title of 'Duke' during his life and after his death was conferred with the title of "Thái Vương", which means "Great Prince". From the time of Trịnh Tùng onwards, members of the Trịnh family were given the title of Prince while in power. Also known with the title of Lord, they had the right to choose the crown prince and had power over political and military matters. During his rule, the war with the Mạc dynasty was successfully completed.
