Ming–Hồ War: Retired King Hồ Quý Ly and his son King Hồ Hán Thương of Hồ dynasty are captured by the Ming armies.

The Ming invasion of Viet, known in Vietnam as the Ming–Đại Ngu War was a military campaign against the kingdom of Đại Ngu under the Hồ dynasty by the Ming dynasty of China. The campaign began with Ming intervention in support of a rival faction to the Hồ dynasty which ruled Đại Ngu, but ended with the incorporation of Đại Ngu into the Ming dynasty as the province of Jiaozhi. The invasion is acknowledged by recent historians as one of the most important wars of the late medieval period, whereas both sides, especially the Ming, used the most advanced weapons in the world at the time.
