The Ming–Hồ War is a military campaign by the Ming Empire of China to invade Đại Ngu (present-day north Vietnam) ruled by the Hồ dynasty.
The campaign begins with a Ming intervention in support of a rival faction to the Hồ, but ends with the incorporation of Vietnam into China, marking the start of the Ming province of Jiaozhi.A few years earlier, Hồ Quý Ly had violently taken the Trần throne, which ultimately led to the intercession of the Ming government to reestablish the Trần dynasty.
However, Hồ's forces attacked a Ming convoy escorting a Trần pretender, who was killed during the attack.
After this hostile event, the Yongle Emperor of the Ming Empire appointa Marquises Zhang Fu and Mu Sheng to prepare and lead the Ming armies for the invasion of Đại Ngu.
The war lasta from 1406 to 1407, resulting in the Ming conquest of Đại Ngu and the capture of the members of the Hồ dynasty.
