Nine-rank system

220 · 3rd century · Also known as Nine-grade controller system

The nine-rank system was a method of selecting officials introduced in 220 under Cao Pi, the first emperor of Cao Wei. Local assessors graded candidates into nine ranks according to their character and ability, and appointments followed the grades. In practice the assessors favoured great families, and the system entrenched an aristocracy in Chinese government until it was replaced under the Sui dynasty.
