安定郡 / Anding Commandery

Overview

安定郡 / Anding Commandery is a frontier commandery restored under 汉顺帝 in Hanji 810 after 虞诩 argues that the evacuated northern commandery belt should not remain abandoned. The page treats Anding as part of a three-commandery restoration package with 北地郡 and 上郡.

Current Profile

Hanji 810 says Yu Xu asks the court to restore Anding, Beidi, and Shangjun and move people back. His argument joins geography, food supply, frontier defense, and imperial security: the region has fertile land, irrigation and transport value, and defensive importance for Chang’an and the imperial tombs.

Shun accepts the proposal in the ninth month of 129 CE and orders the commanderies restored. Anding’s current wiki significance is therefore not simply as a map unit, but as a case where abandoned frontier administration is reframed as recoverable state capacity.

Key Characteristics

• Frontier commandery restored as part of a strategic northern package.
• Linked to arable land, water management, transport, pasture, and defense rather than administration alone.
• Treated as protective terrain for Chang’an and imperial tombs.
• Reoccupied through imperial order after Yu Xu’s memorial.
• Source-bounded place page, not yet a full historical geography entry.

Evidence

• Restoration proposal: Hanji 810 says Yu Xu proposes restoring Anding, Beidi, and Shangjun.
• Strategic rationale: Hanji 810 frames the region as fertile, logistically useful, and defensive for Chang’an and imperial tombs.
• Imperial acceptance: Hanji 810 says Shun issues the order in the ninth month to restore the commanderies and return people.

Qualifications

This page follows Hanji 810’s restoration argument and does not settle Anding’s exact historical boundaries, earlier abandonment chronology, or later administrative changes. Because Beidi and Shangjun already have their own pages, this page focuses on Anding’s role in the three-commandery restoration case.

What Changed

• Created the Anding Commandery page to avoid a missing route in Yu Xu’s three-commandery restoration proposal.

Relationships

• 虞诩 - official whose memorial makes Anding’s restoration a policy issue.
• 汉顺帝 - ruler who orders Anding and the neighboring commanderies restored.
• 北地郡 - paired commandery in the same restoration package.
• 上郡 - paired commandery in the same restoration package.
• 边郡恢复治理 - concept directly grounded by the Anding restoration case.
