渤海郡 / Bohai Commandery (late Han)
渤海郡 / Bohai Commandery (late Han) enters the wiki through Hanji 958 as the office 袁绍 gives to 公孙范 after 公孙瓒 blames Yuan Shao for 公孙越’s death. Yuan Shao appears to use the commandery as an appeasement or de-escalation signal.
The episode’s point is that an office is also a military resource. Gongsun Fan brings Bohai’s troops over to Gongsun Zan, so the concession strengthens Yuan Shao’s rival instead of calming him. Bohai therefore becomes a compact source case for how 利益结构式联盟脆弱性 can turn title grants and commandery control into defections.
