Zhuo Commandery

Zhuo Commandery (Chinese: 涿郡) or Fanyang Commandery (Chinese: 范陽郡ぐん) was a commandery in imperial China from Han dynasty to Tang dynasty, located in modern Hebei and Beijing.

Han dynasty

Zhuo Commandery was established during Emperor Gao of Han's reign from the Qin-era Guangyang, Julu and Hengshan commanderies, with the seat at Zhuo (涿, modern Zhuozhou). In Western Han dynasty, it administered 29 counties: Zhuo, Nai (迺), Guqiu (穀こく丘おか), Gu'an (故こ安やす), Nan Shenze (南みなみ深澤ふかさわ), Fanyang (范陽), Liwu (蠡吾), Rongcheng (容よう城じょう), Yi (易えき), Guangwang (廣こう望もち), Mao (鄚), Gaoyang (高こう陽よう), Zhouxiang (州しゅう鄉きょう), Anping (安平あびら), Fanyu (樊輿), Cheng (成なり), Liangxiang (良鄉よしさと), Lixiang (利り鄉きょう), Linxiang (臨鄉), Yichang (益えき昌あきら), Yangxiang (陽ひ鄉きょう), Xixiang (西鄉さいごう), Raoyang (饒にょう陽ひ), Zhongshui (中ちゅう水すい), Wuyuan (武たけ垣かき), Aling (阿おもね陵りょう), Awu (阿武あぶ), Gaoguo (高こう郭くるわ) and Xinchang (新あたらし昌あきら). In 2 AD, the population was 782,764, in 195,670 households. Most of the counties were abolished in Eastern Han, and only 7 counties were listed in the Book of Later Han: Zhuo, Nai, Gu'an, Liangxiang, Bei Xincheng (北きた新城しんじょう) and Fangcheng (方城ほうじょう, formerly part of Guangyang). In 140 AD, the population was 633,754, in 102,218 households.

Cao Wei and Jin dynasty

During Emperor Wen of Wei's reign, Zhuo was renamed Fanyang (范陽). After the establishment of Jin dynasty, the territory was reorganized into the Principality of Fanyang (范陽國こく). Three princes held the title Prince of Fanyang:

• Sima Sui (司馬しば綏), Prince Kang (康やすし) of Fanyang, 265–279;
• Sima Xiao (司馬しば虓), 279–306;
• Sima Li (司馬しば黎はじむ), 306, killed during the War of the Eight Princes.

The principality consisted of 8 counties: Zhuo, Liangxiang, Fangcheng, Changxiang (長鄉ながさと), Nai, Gu'an, Fanyang and Rongcheng. The population was 11,000 households in 280 AD.

Sui and Tang dynasties

In Sui and Tang dynasties, Zhuo Commandery (before 742) and Fanyang Commandery (after 742) were alternative names of the You Prefecture (幽かそけ州しゅう). It administered 9 counties, and the population in 742 was 371,312, in 67,243 households. The seat was Ji (present-day Beijing).
