Map Introduction

The evolution of Jiao Province and Guang Province during the Western Jin period primarily involved administrative adjustments and political turmoil.

Evolution of Jiao Province

After the establishment of the Western Jin, Jiao Province remained under the control of Eastern Wu. However, due to internal strife within Eastern Wu, such as the rebellion of Lü Xing in 263 AD, Jiao Province was effectively fragmented. In 264 AD, in an attempt to stabilize the situation, Eastern Wu carved out four northern commanderies of Jiao Province—Nanhai, Cangwu, Yulin, and Hepu—to create a separate Guang Province, with its administrative seat at Panyu (modern Guangzhou). While this move temporarily restored unity to the remaining Jiao Province, it sowed the seeds for future instability.

Evolution of Guang Province

Guang Province was originally territory under Eastern Wu. After its establishment from part of Jiao Province in 264 AD, Panyu became the political center of the Lingnan region. Following the Western Jin's conquest of Eastern Wu in 280 AD, Guang Province largely retained the administrative structure of its predecessor. Being distant from the conflicts of the Central Plains, it developed into a relatively stable area. By the mid-3rd century, as the Dayu Ling Route became the main overland passage, Guang Province's advantages in trade were further cemented, solidifying its status.

Key Events

• 279 AD: The Rebellion of Guo Ma. The Eastern Wu general Guo Ma launched a rebellion in Guang Province, killing the Eastern Wu military governor of the province. The rebellion was later suppressed by Jin forces.
• 280 AD: Following the fall of Eastern Wu, Guang Province came under Western Jin control. Its distance from the Central Plains spared it from major conflicts, leading to a period of relative social stability.
• Mid-to-Late 3rd Century: Guang Province emerged as a significant port on the Maritime Silk Road. Its strategic advantages in both land and maritime transportation propelled its development into a regional economic center.

Administrative Characteristics

During the Western Jin period, Guang Province initially continued the old Eastern Wu system, with its seat in Nanhai Commandery. Although briefly established as a separate province (e.g., in 264 AD), it did not immediately solidify as a stable top-level administrative division and initially remained administratively dependent on the structure of Jiao Province.
