During the Han Dynasty (206 B.C.-A.D. 220), agriculture, handicrafts, and commerce were well developed. During the reign of Emperor Wudi (Liu Che, 140-87 B.C.), the Han regime reached the period of its greatest prosperity. The multi-ethnic country became more united during the Han regime, which existed in total 426 years.

The emperor conquered the Xiongnu nomads, sent Zhang Qian as an envoy to the Western Regions (Central Asia), and in the process pioneered the route known as the "Silk Road" from the Han capital Chang' an through Xinjiang to Europe.

One of the Four Beauties of Ancient China, Wang Zhaojun, was married as a ‘political bride’ to chieftain of the Xiongnu in 33 B.C. Her life and influence created a famous inspiring story about marriage between the Han and the Xiongnu.
