Yan Kingdom (Han dynasty)

In 202 BC, Zang swore fealty to Liu Bang, the founder of Han dynasty.

Yan was subsequently granted to Lu Wan, a trusted general and early follower of the emperor.

The Yan territories in early Han dynasty consisted of six Qin-era commanderies, including Shanggu, Yuyang, Youbeiping, Liaoxi, Liaodong and Guangyang.

Five of them were revoked around 155 BC, and the remaining territory was equivalent to the Guangyang Commandery of Qin dynasty.

[6] After the Jin dynasty was established, the principality was granted to Sima Ji (司馬機), and Yuyang Commandery was added to its territory.
