Annan command

In 1527, An Hưng vương Mạc Đăng Dung, a powerful minister of the Later Lê dynasty in Đại Việt (present-day northern Vietnam), forced Lê Cung Hoàng to abdicate and established the Mạc dynasty, with the capital still in Thăng Long, and adopted Minh Đức as his era name.

Nguyễn Kim, the former general of the Later Lê dynasty, fled to Lan Xang (Ai Lao) with his family after Mạc Đăng Dung's usurpation.

In January of the following year, Đăng Doanh officially ascended the throne and became known as Mạc Thái Tông, changing the era name to Đại Chính.

[1] In 1537, Lê Trang Tông sent envoys to Beijing to accuse the Mạc family of usurping the throne and requested the Ming dynasty to attack them.

[7][6] This event marked the Ming dynasty's decision to demote Annan from a vassal state (國; guo; quốc) to a subordinate territory (都統使司; dutongshisi; Đô thống sứ ty).

[5] Mạc Đăng Dung was appointed as the Commandant of Annan with a second-class hereditary rank and was required to pay tribute every three years.
