Cangwu Commandery (Chinese: 蒼梧郡) was a Chinese commandery that existed from Han dynasty to Tang dynasty. Cangwu's territory was located in the modern provinces of Guangxi and Guangdong, with its capital at Guangxin (廣信), present-day Wuzhou.[1]


Cangwu Commandery was established in 112 BC, when the Han dynasty annexed the Nanyue kingdom. In late Western Han period, it had a population of 24,739 households (146,160 individuals) in its 10 counties, namely Guangxin, Xiemu (謝沐), Gaoyao (高要), Fengyang (封陽), Linhe (臨賀), Duanxi (端谿), Fengcheng (馮乘), Fuchuan (富川), Lipu (荔蒲), Mengling (猛陵).[2] During the Eastern Han period, a new county, Zhangping (鄣平), was added. The population in 140 AD was 111,395 households (466,975 individuals).[3]

During the Three Kingdoms, Cangwu was part of Eastern Wu, and a number of counties were created in this period. In 226, a new commandery, Linhe, was split off from Cangwu. When Jin dynasty unified China in 280, Cangwu consisted of 12 counties and recorded a population of 7,700 households.[4]

During the reign of Emperor Mu of Jin, three more commanderies – Jinkang (晉康), Xinning (新寧) and Yongping (永平) – were created on the lands of Cangwu. In 464, the population was 4,547 households (17,710 individuals).[5] The commandery was abolished when the Sui dynasty conquered the Chen dynasty.[6]

In Sui and Tang dynasties, Cangwu Commandery was an alternative name of Feng Prefecture, later renamed Wu Prefecture in 621. The commandery consisted of 3 counties, and had a population of 1,290 households in 741.[7]
