What happened

After decades of court corruption and weakening central authority, two major Daoist-influenced uprisings, the Yellow Turban Rebellion and the Five Pecks of Rice Rebellion, broke out in 184 CE. To suppress them, the Han court granted regional military commanders direct control over their own provinces, a decision that let warlords entrench themselves once the rebellions were crushed. The warlord Cao Cao, who wrote poetry describing armor so infested with lice that lineages had perished and fields lay littered with bones, tried to reunify the empire by force but was defeated at the Battle of Red Cliffs in 208 CE. When Cao Cao died in 220 CE, the last Han emperor abdicated, and China split into three rival states, Cao Wei, Shu Han, and Eastern Wu, beginning the Three Kingdoms period that lasted until 280 CE.

Why it matters

The Three Kingdoms period, despite nearly constant war, became one of the most romanticized eras in Chinese cultural memory, and its collapse of central authority demonstrated how quickly a decision made under military necessity, granting commanders provincial control, could dissolve unified rule once the original threat passed. The fragmentation would not be permanently healed until the Sui reunification more than three and a half centuries later.

How we know

The period is documented in Chen Shou's near-contemporary Records of the Three Kingdoms, and Cao Cao's own surviving poetry offers a rare first-person account of the era's devastation from a leading participant.
