《资治通鉴·汉纪》149｜西楚霸王项羽为何弑君（2）
Summary
This 芮淇讲透资治通鉴 episode follows Hanji 149 part 1 by shifting from 芈心 / 楚怀王’s killing to the rapid territorial consequences of 刘邦’s eastward move. Liu Bang absorbs 申阳’s Henan territory, installs 韩王信 after 郑昌 surrenders, moves his capital to 栎阳, and pushes into Longxi, Beidi, Wei, and Henei. The counterpoint is 项羽’s punitive Qi campaign: after 田荣 is killed, Xiang Yu continues killing, burning, and plundering, turning possible submission into renewed resistance.
Key Claims
- After killing 韩成, Xiang Yu makes 郑昌 king of Han, but the choice exposes his reliance on old Xiang-line loyalists rather than a durable Han restoration settlement.
- 刘邦 receives 申阳’s surrender, converts the former Henan kingdom into 河南郡, and uses commandery administration to absorb settlement lords.
- 韩王信 is distinct from the general 韩信; Liu Bang uses him as an old Han royal descendant to reclaim Han legitimacy and administer Yingchuan.
- Zheng Chang’s surrender lets Liu Bang replace Xiang Yu’s Han king with Han Wang Xin, pulling old Han territory further into the Liu Bang camp.
- Liu Bang moves his capital to 栎阳, takes 陇西郡, then takes 北地郡 after defeating 章平.
- The episode frames the Guanzhong rear as Liu Bang’s base: 萧何 governs, 韩信 handles military affairs, and frontier repairs guard against Xiongnu pressure.
- 项羽 defeats 田荣 in Qi, but Tian Rong’s death does not pacify Qi because Xiang Yu continues killing surrendered troops, destroying cities, and plundering civilians.
- Xiang Yu’s Qi violence is treated as a major strategic error: it turns local willingness to submit into forced resistance, extending 暴行反噬式动员 from a siege or hostage case to occupation policy.
- 魏豹 surrenders to Liu Bang quickly because Xiang Yu’s partition has reduced and reshaped his territory; grievance over allocation becomes a direct defection channel.
- Liu Bang captures 司马卬, turns the occupied space into 河内郡, and breaks the Yellow River containment line that Xiang Yu had relied on.
