Trịnh lords
Trịnh Sâm (Vietnamese: 鄭森, 9 February 1739 – 13 September 1782) ruled northern Vietnam from 1767 to 1782 AD. He ruled with the title "Tĩnh Đô Vương" (Vietnamese: 靖都王, lit. 'Viceroy Tinh Do') and was one of the last of the powerful Trịnh lords. Trịnh Sâm defeated the ancient enemy of the northern state, the Nguyễn lords in the south. The Trịnh line was separate from the royal Lê dynasty, and the officially recognized emperor was Lê Hiển Tông (1740–1786), who continued to occupy the royal throne in Thăng Long (modern-day Hanoi), but without real power.
