## What happened

In 1418 Le Loi, a landowner from Thanh Hoa, rose against Ming rule at Lam Son. From guerrilla survival in the hills the movement grew into a national army, guided politically by the scholar-strategist Nguyen Trai, whose letters and proclamations sapped the will of the Ming garrisons.

Victory came at Chi Lang–Xuong Giang in 1427, where a Ming relief army was destroyed and its commander Liu Sheng was killed. The remaining garrisons were allowed to withdraw.

## Background

Ming China had annexed Dai Viet in 1407. In documented Vietnamese complaints, the occupation is remembered for heavy taxation, cultural suppression, and the confiscation or destruction of Vietnamese books.

## Consequences

Le Loi founded the Later Le dynasty in 1428. Nguyen Trai's victory proclamation, the *Binh Ngo Dai Cao*, is remembered in Vietnam as a great declaration of independence.
