Captured Ruler Legitimacy Containment / 生俘亡君的合法性钳制

Captured ruler legitimacy containment / 生俘亡君的合法性钳制 is the conquest tactic 《资治通鉴·秦纪》114-1｜今天聊聊 嬴政都有哪些残忍手段 develops through 赵迁 / 赵幽缪王. After 秦国 captures 邯郸, Zhao Qian is not killed; he is moved away from the capital and held as a defeated ruler.

The host’s interpretation is that this is not only mercy. As long as Zhao Qian is alive, 赵嘉 has a harder time calling himself king of Zhao, because the last recognized Zhao king still exists under Qin control. The captured ruler becomes a political object: powerless enough to be harmless militarily, but alive enough to blunt the legitimacy of a remnant claimant.

This differs from 不爱杀人者能一之. The point is not humane settlement or popular attraction; it is coercive preservation of a rival’s formal residue so that post-conquest resistance has weaker naming power.

Key Claims

• A conquered ruler can be more useful alive than dead when his survival weakens rival succession claims.
• Captivity can separate person, office, and political usefulness: the person loses power, but the office residue still constrains others.
• The tactic is distinct from benevolent restraint because the goal is control of legitimacy, not restoration or reconciliation.
• A remnant claimant may choose a regional title when the old royal title is blocked by the living captive ruler.

Connections

• 赵迁 / 赵幽缪王 - captured ruler used in the source case.
• 赵嘉 - displaced prince whose claim is constrained.
• 秦国, 嬴政 / 秦始皇, and 邯郸 - conquering state, ruler, and captured capital.
• 代地 / 代国 and 残余政权根据地 - alternate title and refuge available to Zhao Jia.
• 不爱杀人者能一之 and 孟子的民本合法性 - contrasting legitimacy frames.
• 楚怀王 - adjacent captured-ruler case where captivity creates coercive leverage rather than title containment.
