The Mạc dynasty (1527–1677), officially Đại Việt, was a Vietnamese dynasty which ruled over a unified Vietnam between 1527 and 1540, and northern Vietnam from 1540 until 1593. The Mạc dynasty lost control over the capital Đông Kinh for the last time in its wars against the Later Lê dynasty and the Trịnh Lords in 1592. Subsequent members of the Mạc dynasty ruled over the province of Cao Bằng with the direct support of the Chinese Ming and Qing dynasties until 1677.
