边疆将领擅断干预 / Unauthorized Frontier Command Intervention

Hanji 917 introduces unauthorized frontier command intervention through 张脩. As protector of Xiongnu, Zhang clashes with 呼征, kills him without prior court authorization, and installs 羌渠 as 南匈奴 chanyu.

The concept names the gap between frontier discretion and central legitimacy. A field official may have local force and immediate knowledge, but succession intervention in an allied frontier polity can exceed delegated authority and create a court-level legality problem.

Key Claims

• Frontier officials can create facts on the ground faster than the center can approve them.
• Local command discretion becomes politically dangerous when it changes leadership succession rather than only battlefield tactics.
• The Han court’s punishment of Zhang Xiu shows that an outcome may be strategically convenient and still legally unauthorized.
• The pattern differs from 边疆征发反噬: here the trigger is unilateral Han-official intervention, not frontier-population backlash against troop requisition.

Connections

• 张脩, 呼征, and 羌渠 — source sequence.
• 南匈奴 — polity whose succession is altered.
• 边疆征发反噬 — later Southern Xiongnu frontier-crisis concept that this one precedes but does not duplicate.
• 君臣反馈失灵 — adjacent late-Han governance failure, though this concept is about command authorization rather than advice channels.
