The Historical Map of Jiangsu and Zhejiang Provinces during the Yuan Dynasty
Map Introduction
I. Establishment Background and Initial Jurisdiction
The Jiangzhe Branch Secretariat was one of the eleven Branch Secretariats of the Yuan Dynasty, established in 1276. Its initial jurisdiction included modern southern Jiangsu, southern Anhui, northeastern Zhejiang, and the entire territory of Fujian. To strengthen centralization, the Yuan Dynasty developed the Branch Secretariat system, adapting previous administrative frameworks to govern a multi-ethnic empire. As a key southeastern region, its seat was successively located in Yangzhou and Hangzhou, ultimately settling in the latter. Its boundaries were adjusted in the mid-Yuan period: in 1291, the area north of the Yangtze was transferred to the Henan Jiangbei Branch Secretariat, and in 1299, the Fujian Branch Secretariat was merged into it, forming its stable territorial extent.
II. Administrative Divisions and Political Status
The Jiangzhe Branch Secretariat operated a four-tier administrative structure of Routes, Superior Prefectures, Subprefectures, and Counties, governing 30 Routes, 1 Superior Prefecture, and 2 Subprefectures. As the primary revenue-generating region of the Yuan, it held a special political status:
- Administrative Structure: Headed by officials including a Chancellor, Executive Administrators, Assistant Administrators, and Participating Administrators, with senior posts predominantly held by Mongol nobles or Semu officials.
- Military Control: While the Branch Secretariat managed both civilian and military affairs, troop deployments required approval from the Central Bureau of Military Affairs, reflecting the Yuan's centralized control.
- Supervisory System: Surveillance Commissions were established to strengthen central oversight.
III. Economic Status and Fiscal Contribution
The Jiangzhe Branch Secretariat was the economic core of the Yuan Empire, characterized by three main features:
- Fiscal Pillar: It contributed approximately 50% of national tax revenue. The region's immense wealth supported the central treasury, with key areas like Hangzhou and Suzhou providing massive grain quotas.
- Agricultural Development: Cultivated land was expanded through land reclamation projects, and major water conservancy works were frequently undertaken. Rice cultivation was highly developed, with grain taxes levied on various crops.
- Commercial Prosperity: Ports like Hangzhou and Quanzhou engaged in frequent overseas trade, while the cotton textile industry emerged in Songjiang, creating a thriving economic landscape.
IV. Cultural Development and Social Features
As the former heartland of the Southern Song, the region exhibited rich cultural diversity:
- Educational Continuity: Academies flourished, continuing the Southern Song scholarly tradition.
- Artistic Achievements: Cities like Suzhou and Nanjing became painting centers, where literati drove artistic innovation.
- Religious Coexistence: Islam, Christianity, and Buddhism coexisted, with archaeological finds in Quanzhou attesting to its multicultural character.
V. Significant Historical Events
- Early Yuan Governance: The Maritime Trade Supervisorate was established in 1277 to manage overseas trade, followed by four maritime bans to control smuggling.
- Late Yuan Turmoil: Rebellions, notably by Zhang Shicheng from 1353, disrupted the Grand Canal grain transport. In 1356, Zhu Yuanzhang's capture of Jinling (Nanjing) created a north-south stalemate.
- Defensive Fortifications: Widespread city-building by various factions in the late Yuan placed heavy burdens on the populace.
VI. Late Yuan Decline and Historical Impact
During the Zhizheng era (1341–1368), the Jiangzhe Branch Secretariat experienced:
- Economic Collapse: Warfare caused widespread devastation, and the interruption of maritime transport severely worsened finances.
- Administrative Dissolution: By 1367, Zhu Yuanzhang's establishment of the Jiangnan Branch Secretariat rendered the Yuan's Jiangzhe Branch Secretariat effectively defunct.
Its historical significance lies in: * Establishing the geographical concept of "Jiangzhe" for the Ming and Qing dynasties; * Providing the prototype for the provincial-level administrative system used by later dynasties; * Influencing the developmental trajectory of the Jiangnan region through its economic and cultural models.
