Lê Văn Duyệt (1763 or 1764 – 3 July 1832) was a Vietnamese general who helped Nguyễn Ánh—the future Emperor Gia Long—put down the Tây Sơn rebellion, unify Vietnam and establish the Nguyễn Dynasty. After the Nguyễn came to power in 1802, Duyệt became a high-ranking mandarin, serving under the first two Nguyễn emperors Gia Long and Minh Mạng.
