Jin reunifies China
The fall of Wu ends the Three Kingdoms era

In 279–280 Jin armies marched on Wu while Wang Jun's fleet sailed down the Yangtze from Sichuan, burning through the iron chains the southerners had stretched across the river. In spring 280 the last Wu ruler Sun Hao surrendered at Jianye, and China was united for the first time since 220 — though not for long.
