The Historical Evolution of Yi Province during the Southern Qi Dynasty (479–502 AD)

The historical evolution of Yi Province during the Southern Qi period was primarily reflected in administrative adjustments and local governance.

Administrative Adjustments

Following the establishment of the Southern Qi Dynasty, the Yi Province region underwent reorganization. In the first year of the Jianyuan era (479 AD), the territory north of Dianjiang County was separated to create Hanchu County (modern Hancu Village, Liemian Town, Wusheng County, Sichuan Province), which was placed under the jurisdiction of Dongdang Quliao Commandery within Yi Province. This administrative refinement demonstrated the Southern Qi's efforts to strengthen control over Yi Province, though it did not alter the region's status as a crucial western territory of the Southern Dynasties.

Characteristics of Local Governance

The Southern Qi continued the administrative structure of Yi Province inherited from the Eastern Jin Dynasty, maintaining its role as the core region of the southwest. Although the Southern Qi lasted only 23 years, its policy focus was primarily on internal stability and management of the imperial clan, resulting in relatively weak control over remote frontier areas. Consequently, Yi Province's function as a link between the frontier and the central government became even more pronounced.

Border Interactions with the Northern Dynasties

The border between the Southern Qi and the Northern Dynasties was long defined by the Qinling Mountains–Huai River line. Situated south of this line, Yi Province served as a vital defensive barrier for the Southern Dynasties against the north. However, during the later Southern Qi period, frequent internal power struggles (such as Xiao Luan's usurpation and the rebellion of Xiao Ziliang) led to a decline in direct control over Yi Province.

In summary, although Yi Province did not experience large-scale political upheaval during the Southern Qi period, it consistently maintained its role in regional administration and its strategic position on the front line of the North-South confrontation.
