Trịnh Khải
Vietnamese lord
Đoan Nam Vương Trịnh Khải (chữ Hán: 鄭楷, 1763-1786) was one of the Trịnh lords in northern Vietnam. He fought against the armies of the infant Trịnh Cán to win leadership of the northern warlords (reigning 29 November 1782 - July 1786), but was himself defeated by the southern warlord, later emperor Nguyễn Huệ. Trịnh Khải later committed suicide. He was succeeded by the last of the lords, Trịnh Bồng.
