Lê–Mạc War
The Lê–Mạc War was a long-time 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.
In 1592, Thang Long, the capital of the Mạc dynasty, was reconquered by the Later Lê forces, marking the end of the Southern and Northern Dynasties period. Mạc rulers fled to Cao Bằng Province with the direct support of the Chinese Ming and Qing dynasties until 1677.
