Tianshui Commandery

Tianshui Commandery (Chinese: 天水てんすい郡ぐん), known as Hanyang Commandery (Chinese: 漢かん陽ひ郡ぐん) during the Eastern Han dynasty, was a historical commandery of China in eastern Gansu. The modern city of Tianshui receives its name from the commandery.

History

The commandery was established from lands of Longxi and Beidi commanderies in 114 BC. In 2 AD, the commandery had 16 counties: Pingxiang (平たいら襄じょう), Jiequan (街まち泉いずみ), Rongyidao (戎えびす邑道), Wangyuan (望もち垣かき), Hanjian (罕幵), Mianzhudao (綿めん諸道しょどう), Ayang (阿おもね陽ひ), Lueyangdao (略りゃく陽ひ道どう), Ji (冀), Yongshi (勇士ゆうし), Chengji (成紀しげのり), Qingshui (清水しみず), Fengjie (奉たてまつ捷とし), Long (隴), Huandao (豲道) and Langan (蘭らん干ひ). The total population was 261,348 (60,370 households). The name was changed to Hanyang in 74 AD. The Eastern Han census in 140 AD documented a population of 130,138 (27,423 households), and the number of counties was 13.

The name "Tianshui" was restored during the Cao Wei. In 280 AD, it administered 6 counties and the population was 8,500 households. During the Northern Wei, it was split into Tianshui and Hanyang commanderies.

During the Sui and Tang dynasties, Tianshui Commandery was an alternative name for Qin Prefecture. The commandery administered 6 counties, and had a population 52,130 households.
