Trịnh lords, Hue

The Trịnh lords, formal title Trịnh Viceroy, also known as Trịnh clan or the House of Trịnh, were a noble feudal clan who de facto ruled northern Vietnam during the Later Lê dynasty, Đại Việt. The Trịnh clan and their rivals, the Nguyễn clan, were both referred by their subjects as Chúa and controlled Đại Việt while the Later Lê emperors were reduced to only a titular position. The Trịnh lords traced their descent from Trịnh Khả, a friend and advisor to the 15th-century Vietnamese Emperor Lê Lợi. The Trịnh clan produced 12 lords who dominated the royal court of Later Lê dynasty and ruled northern Vietnam for more than 2 centuries. ()
