ConflictThird month of 280

Jin Conquest of Wu and Reunification of China

Also called: Conquest of Wu by Jin

When Western Jin forces sailed down the Yangtze to Jianye, the Wu emperor Sun Hao surrendered. The division that had begun in the late Han ended and China was reunified.

At the end of 279 Emperor Wu of Jin (Sima Yan) sent over 200,000 troops against Wu along several routes. Wang Jun’s fleet, built in Yi Province, burned through the iron chains across the Yangtze, swept downstream and reached Jianye in the third month of 280, where Sun Hao surrendered. The Three Kingdoms era was over. Yet the Western Jin was soon shaken by the War of the Eight Princes and invasions by northern peoples and fell in 316, and China split again into north and south.
