Dai Prefecture, also known by its Chinese name Daizhou, was a prefecture (zhou) of imperial China in what is now northern Shanxi. It existed intermittently from AD585 to 1912. Its eponymous seat Daizhou was located at Shangguan in Dai County. The territory it administered included all or part of what are now the counties of Dai, Wutai, Fanshi, and Yuanping in Shanxi's Xinzhou Prefecture.
Name
Dàizhōu is the pinyin form of the Standard Mandarin reading of the Chineseplacename代州. In the system of romanization devised by Thomas Wade and systematized by Herbert Giles, the same pronunciation is written Tai Prefecture, Tai Chou, or Tai-chou. It appeared as Taichow or TaichowSha on the Chinese Postal Map.[1] Although "prefecture" only refers to an administrative office or area in English,[2] the Chinese name can refer to either the prefecture or to the prefectural seat at old or new Guangwu.[3] The prefectural seat was also known for a time as Yanmen.[4][5] During periods when the prefecture was demoted to county status, its seat was also known as Daixian.
Dai Prefecture was reëstablished by the Tang in 618, abolished and merged with Yanmen Commandery again in 742, and reëstablished a second time a few years later in 758.[3][14] Under the Tang, it formed part of Hedong Circuit. During this period, the seat at Daizhou administered a prefecture covering what are now the counties of Dai, Wutai, Fanshi, and Yuanping.[14][15]
