Map Introduction

Qingzhou and Xuzhou during the Cao Wei period underwent complex evolution in terms of administrative divisions, military governance, and historical events, primarily reflected in the following aspects:

Administrative Adjustments

During the Cao Wei era, the administrative seat of Qingzhou was located in Guang County (modern Qingzhou City, Shandong Province). Its jurisdiction covered the area from modern eastern Shandong to the region around Mount Tai and the eastern bank of the Yellow River. Xuzhou, with its administrative center at Pengcheng County (modern Xuzhou City), established Pengcheng Commandery, which later became synonymous with Xuzhou itself. Qingzhou administered five commanderies: Beihai, Donglai, Qi, Jinan, and Le'an. In contrast, Xuzhou under Cao Wei did not establish formal commandery-level administrations and was primarily controlled by local powers such as Zang Ba.

Military and Administrative Control

Following the Yellow Turban Rebellion, Qingzhou became a crucial source of troops for Cao Cao, with nearly a million Yellow Turban adherents surrendering to him and forming the elite "Qingzhou Troops." In Xuzhou, the Yellow Turban forces were gradually suppressed and dispersed under attacks by regional leaders like Tao Qian, with some remnants aligning with powerful local families to form semi-autonomous enclaves. In the later Cao Wei period, Qingzhou was nominally governed by a prince from the imperial clan, Cao Rui, but actual administration was carried out by centrally-appointed officials.

Key Historical Events

• Yellow Turban Rebellion (184 AD): The massive scale of the Yellow Turban forces in Qingzhou provided a significant military resource for Cao Cao.
• Battle of Guandu (200 AD): Qingzhou served as a strategic buffer zone between the rival forces of Yuan Shao and Cao Cao.
• Cao Cao's Pacification of Qingzhou (post-204 AD): Through military campaigns, Cao Cao gradually secured control over Qingzhou. The subsequent submission of leaders like Zang Ba resulted in a semi-autonomous governance structure.
• Control of Salt and Iron in Donglai: The revenue from salt and iron production on the Jiaodong Peninsula accounted for over 20% of the Cao Wei state's total, leading to an integrated military and economic governance system.

Special Governance Model

The Cao Wei administration implemented a strategy of "military leadership over administration" in Qingzhou, where military commanders oversaw civil affairs and the allocation of economic resources. For instance, the salt works and iron offices in Donglai Commandery were directly managed by the central government. Their annual output of 150,000 shi of grain was dedicated exclusively to supplying garrison troops, creating a militarized governance model that integrated soldiering and farming.
