伊吾屯田 / Yiwu Garrison Farming (late Han)

Overview

伊吾屯田 / Yiwu garrison farming is the late-Han Western Regions garrison-agriculture installation whose current profile now begins with Dou Gu taking Yiwu in the 73 CE campaign, then runs through 77 CE withdrawal and Northern Xiongnu reoccupation, and later restoration under 汉顺帝 in 131 CE. The route is deliberately disambiguated from the modern Yiwu page because this page refers to Western Regions garrison agriculture and the office of Yiwu sima.

Current Profile

Hanji 741 supplies the backfilled origin layer. In Mingdi’s 73 CE four-route campaign against Northern Xiongnu, Dou Gu’s route reaches Tianshan, attacks the Huyan king, takes Yiwu, and stations soldiers there. Yiwu therefore enters the current wiki as a conquered and occupied route node before it becomes a withdrawal problem.

Hanji 747 supplies the 77 CE contraction layer. Zhangdi withdraws the Yiwu Lu tuntian troops, and Northern Xiongnu occupies the position again. The notice makes Yiwu a compact example of strategic frontier abandonment: a removed garrison becomes an enemy-held route node almost immediately.

Hanji 810 supplies the later restoration layer. Shun restores Yiwu tuntian in 131 CE and establishes a Yiwu sima, following an earlier model from the Yongyuan reign. Yiwu’s current profile therefore joins conquest, garrison farming, withdrawal risk, and restored corridor security.

Key Characteristics

• Western Regions route-security installation rather than a modern city route.
• Captured and garrisoned after Dou Gu’s 73 CE Tianshan success.
• Tuntian site where agriculture and garrison logistics are combined.
• Withdrawal case where abandoned position is reoccupied by Northern Xiongnu.
• Restored by Shun as a deliberate revival of an earlier frontier model.
• Given a named office, Yiwu sima, to administer the restored position.

Evidence

• Capture and initial garrison: Hanji 741 says Dou Gu takes Yiwu after the Tianshan/Huyan king action and stations soldiers there.
• Withdrawal notice: Hanji 747 says Zhangdi withdraws the Yiwu Lu tuntian troops in 77 CE.
• Enemy occupation: Hanji 747 says Northern Xiongnu occupies Yiwu again after the withdrawal.
• Restoration notice: Hanji 810 says Shun restores Yiwu tuntian in 131 CE.
• Administrative office: Hanji 810 says the court establishes a Yiwu sima.

Qualifications

The page should not be merged with the modern Yiwu page. It is a source-bounded Western Regions garrison-farming site. Exact ancient geography, the Hami identification, Yiwu Lu wording, and the full administrative chain remain source-scoped.

What Changed

• Added Hanji 741’s 73 CE capture-and-garrison layer before the existing 77 CE withdrawal and 131 CE restoration layers.
• Reframed Yiwu as a conquest-to-withdrawal-to-restoration node rather than only a Shun-era revival.
• Preserved the disambiguation from modern Yiwu.

Relationships

• 窦固 / Dou Gu (Eastern Han) - commander whose 73 CE route takes and garrisons Yiwu.
• 汉明帝 / Emperor Ming of Han - ruler whose anti-Northern-Xiongnu campaign creates the first current Yiwu layer.
• 北匈奴 / Northern Xiongnu (late Han) - opponent displaced in 73 CE and beneficiary of the 77 CE withdrawal.
• 汉章帝 / Emperor Zhang of Han - ruler whose reign includes the Yiwu withdrawal.
• 汉顺帝 / Emperor Shun of Han - ruler whose reign restores Yiwu tuntian and creates the Yiwu sima office.
• Strategic Frontier Abandonment / 弃边失屏 - concept illustrated by the 77 CE withdrawal and reoccupation.
