Dong Commandery

[1] In early Western Han dynasty, the commandery became a part of the Liang Kingdom,[2] which was subsequently abolished during the Lü Clan Disturbance.

[3] In late Western Han dynasty, the commandery administered 22 counties and marquessates: Puyang (濮陽), Panguan (畔觀), Liaocheng (聊城), Dunqiu (頓丘), Fagan (發干), Fan (范), Chaping (茬平), Dongwuyang (東武陽), Boping (博平), Li (黎), Qing (清), Dong'e (東阿), Lihu (離狐), Linyi (臨邑), Limiao (利苗), Xuchang (須昌), Shouliang (壽良), Lechang (樂昌), Yangping (陽平), Baima (白馬), Nanyan (南燕) and Linqiu (廩丘).

[4] The commandery went through a series of administrative changes in the Eastern Han dynasty, and by 140 CE, 15 counties remained in the commandery: Puyang, Yan (formerly Nanyan), Baima, Dunqiu, Dong'e, Dongwuyang, Fan, Linyi, Boping, Liaocheng, Fagan, Leping (樂平, formerly Qing), Yangping, Wei (衞, the fief of the descendants of the Zhou dynasty kings[5]) and Gucheng (穀城).

After the foundation of Jin dynasty, the commandery was converted to Puyang Principality (濮陽國) and successively served as the fief of several imperial princes.

Under Northern Wei, Dong Commandery administered seven counties in the mid-6th century: Dongyan (東燕), Pingchang (平昌), Baima, Liangcheng (涼城), Suanzao (酸棗, formerly part of Chenliu Commandery), Changyuan (長垣, formerly part of Chenliu) and Changle (長樂).
