The Lê–Mạc War (Vietnamese: Chiến tranh Lê-Mạc; Hán tự: 戰爭黎莫) was a 59 year-long civil war waged between two Vietnamese dynasties, the Mạc and Revival Lê, during the Southern and Northern Dynasties period of Vietnamese history. The Vietnamese throne was usurped by Mạc Đăng Dung in 1527. Lê Ninh, a prince of the Later Lê dynasty, escaped to Lan Xang. In 1533, Lê Ninh proclaimed himself emperor with the support of Nguyễn Kim and Trịnh Kiểm. The civil war between the two dynasties thus ensued.
