## Overview

Yang Jian (Emperor Wen) took the throne of the Northern Zhou in 581 and conquered the southern Chen in 589, reunifying China. His reforms included a new legal code, centralized administration, and the beginnings of the civil-service examination system.

## Key developments

Emperor Yang (Yangdi) built the Grand Canal between 605 and 610, linking the Yellow River and Yangtze regions. The dynasty is often compared to the Qin: short, harsh, and transformative.

## End and transition

Massive conscripted labor and failed campaigns against Goguryeo in Korea exhausted the state. Rebellions spread, and Yangdi was assassinated in 618.
