Shangyong Commandery (上庸郡) was a short-lived but strategically vital commandery astride the upper Han River between the Qinling Mountains and the Wuling Mountains. Founded in 215 CE to control the mountain corridor that linked Hanzhong with central Jingzhou, it became the focal point of several contests among the warlords Cao Cao, Liu Bei and their successors. The unit survived—with interruptions—into the sixth century, when the Liang dynasty finally abolished it.
Geography and counties
[edit]At its creation the commandery governed five rugged hill counties:[2]
| County (治所) | Location (modern) | Notes |
|---|---|---|
| Shangyong ✪ | Zhushan County, Hubei | Commandery seat beside the upper Dan (沔) River |
| Beiwu | Zhuxi County, Hubei | Controlled passes toward the Wudang range |
| Anle | Western Zhushan, Hubei | Garrison of the “Peace Pass” (安樂關) |
| Wuling | Fang County, Hubei | Not to be confused with the Wuling of modern Hunan |
| Anfu | Pingli County, Shaanxi | Guarded the northern outlet into the Qinling |
| Weiyang | Southern Pingli, Shaanxi | Listed only in late-Han registers |
Steep karst terrain limited agriculture; most Han settlers were soldier-farmers posted to timber and iron-ore depots that supplied river fleets on the Han and Yangtze.
History
[edit]Eastern Han foundation (215 – 220 CE)
[edit]In the summer of 215 Emperor Xian approved Cao Cao’s memorial to split Hanzhong: the eastern hill districts became Shangyong Commandery under Administrator Shen Dan.[3] The reorganisation created a forward glacis against both Liu Bei (then attacking Hanzhong from the west) and Sun Quan (pressuring Jiangling downstream).
After capturing Hanzhong, Liu Bei dispatched Liu Feng and Meng Da down the Dan River. Shen Dan capitulated; neighbouring Fangling and Xicheng likewise fell, giving Shu control of the so-called “Eastern Three Commanderies.”[4]
Xiahou Shang retook the area in 221. Emperor Cao Pi merged Shangyong with neighbouring Fangling into Xincheng Commandery, then soon separated its western counties again as a reduced Shangyong Commandery.[5]
Western Jin administration (265 – 316 CE)
[edit]Western Jin placed the commandery in Liang Province. Gazetteers list three counties (Shangyong, Beiwu, Anle) totalling about 5 800 households.[6] Frequent raids by Di and Ba tribal groups kept population low.
Sixteen Kingdoms & Southern dynasties (4th – 6th centuries)
[edit]From 316 CE the region oscillated between Former Qin, Later Qin and Qiao-Qiang chiefdoms, before falling under Liu Song (430s) and Southern Qi. In 504 the Liang dynasty attached it to the new Dong-Liang Zhou. When Western Wei overran the upper Han valley (553 – 557) the commandery was finally abolished.[1]
Strategic significance
[edit]Shangyong straddled the only practicable mountain corridor linking the Han River headwaters with Hanzhong and the Sichuan Basin. Control of the commandery
- threatened Wei’s lateral supply route between Chang'an and Jiangling;
- offered Shu a springboard toward Xiangyang;
- shielded Dan River boatyards that fed grain down to the middle Yangtze.
Hence each of the Three Kingdoms struggled to secure or neutralise this district despite its meagre tax base.
Archaeology
[edit]Excavations at Dushui (堵水) near Zhushan have produced Han wooden tallies for iron deliveries, Western Jin stamped bricks, and Liang-era Buddhist cliff carvings, corroborating textual accounts of continuous but turbulent occupation.
