Dai Commandery was a commandery (jùn) of the state of Zhao established c. 300 BC and of northern imperial Chinese dynasties until the time of the Emperor Wen of the Sui dynasty (r. AD 581–604). It occupied lands in what is now Hebei,Shanxi,and Inner Mongolia. Its seat was usually at Dai or Daixian (near present-day Yuzhou in Hebei),although it was moved to Gaoliu (present-day Yanggao in Shanxi) during the Eastern Han.
The name derives from the White Di kingdom of Dai,conquered by the Zhao family of Jin. [1]
Dai Commandery was first established around 300 BC during China's Warring States Period by the state of Zhao's King Yong, posthumously known as the Wuling ("Martial-&-Numinous") King. [2] The commandery seat—then known as Dai—was southwest of present-day Yuzhou in Hebei. [3] It was the former capital of the independent state of Dai, which had been conquered by King Yong's ancestors around 476 BC. [4] He created Dai Commandery along with its companion commanderies of Yanmen and Yunzhong to consolidate his conquests [2] from invasions of the Loufan ( t 樓煩 , s 楼烦 ,Lóufán) and "forest nomads" ( 林 胡 ,Línhú) in 306 and 304 BC. [5]
Following the Qin conquest of Zhao, Zhao Jia attempted to regroup at Dai, declaring himself its king. [4] This Kingdom of Dai was ended by Qin in 222 BC, [4] just prior to the declaration of the Qin Empire two years later.
Dai Commandery was one of the divisions of the Qin Empire. [6] Its seat—then known as Daixian—continued to be near present-day Yuzhou. [7]
