Map Introduction

The Laixiang Military Governorship was a hybrid military-administrative institution established by the Shu Han regime to control the Nanzhong region (modern Yunnan, Guizhou, and southwestern Sichuan). Its historical evolution can be divided into several key phases:

Background of its Establishment

In 221 AD, the first year of the Zhangwu era, Liu Bei sought to consolidate control over the strategic Nanzhong region. He established the Laixiang Military Governorship in Pingyi County (modern Bijie, Guizhou). This office held supreme authority over the four key commanderies of the south—Yizhou, Zangke, Zhuti, and another—garrisoning substantial troops there to form a military stronghold.

Core Functions

The Laixiang Military Governorship held three primary powers: * Military Command: It exercised control over all garrison forces in Nanzhong, including both Han Chinese troops and indigenous tribal contingents. * Administrative Jurisdiction: It supervised the administration of the various commandery governors and could directly intervene in local affairs. * Authority over Ethnic Affairs: It handled disputes with the indigenous tribes and was responsible for the allocation of resources.

Tenure of successive Military Governors

• Deng Fang (c. 215–221 AD): The first Military Governor, stationed at Nanchang County (modern Zhenxiong, Yunnan). He died in office due to illness.
• Li Hui (221–231 AD): Succeeded Deng Fang and moved the headquarters to Pingyi County. He was responsible for tax collection to fund military expenditures and also died in office from illness.
• Zhang Yi (231–233 AD): Assumed the post after Li Hui but was reassigned following rebellions in Nanzhong.
• Ma Zhong (233–249 AD): After suppressing the rebellion of Liu Zhou, he relocated the Governorship's seat to Wei County (modern Qujing, Yunnan), significantly strengthening Shu Han's control over Nanzhong.

Strategic Significance

Through this dual military and administrative apparatus, the Laixiang Military Governorship maintained effective Shu Han control over the Nanzhong region. It ensured this area remained a vital source of military supplies and manpower for Shu Han, a role it sustained until the state's fall in 263 AD.
