Dinh Vuong Nguyen Phuc Thuan or Lord Nguyen Phuc Thuan (1754?1777) was one of the Nguyen lords who ruled over the southern portion of Vietnam from the 16th?18th centuries. The collapse of the house of Nguyen lords intensified during Thuans reign; many uprisings broke out throughout the central part of Vietnam; including the Tay Son revolt; and the offensive of Trinh lords from northern Vietnam. Nguyen Phuc Thuan tried to re-establish the Nguyen lords authority but without success. Eventually; he was captured and executed along with his followers and almost all of his family members by Tay Son rebel general Nguyen Hue in 1777.
