河南郡 / Henan Commandery (Chu-Han)
河南郡 / Henan Commandery (Chu-Han) enters the wiki through Hanji 149 part 2 as the administrative form 刘邦 gives to 申阳’s surrendered territory. The page is disambiguated from modern Henan and unrelated Henan-named modern entities.
The episode treats this as more than a label change. 项羽 had rewarded Shen Yang as Henan king because he took Sanchuan and welcomed the Chu army; Liu Bang’s takeover converts that settlement kingdom into commandery administration. It therefore links old 三川 geography, Chu-Han title allocation, and Liu Bang’s growing preference for direct control over newly acquired territory.
The same source pairs Henan Commandery with 颍川郡 under 韩王信, showing that Liu Bang can combine commandery conversion with restored-royal title politics when it helps absorb old 韩国 ground.
