Historical Fact Analysis: Xiao Daocheng in Zizhi Tongjian and the Theory of "Rule by Four Nobles"

Brief Introduction

In historical popularization, there are occasional mentions of a theory during the period of Xiao Daocheng, the founding emperor of the Southern Qi Dynasty, known as "Rule by Four Nobles." This suggests that Xiao Daocheng and three others took turns making decisions. However, upon examining Zizhi Tongjian and official historical records, this term is not a standard historical concept. This article aims to clarify the actual power structure of Xiao Daocheng from the end of the Liu Song Dynasty to the early Southern Qi Dynasty, based on the original text of Zizhi Tongjian, and to correct historical misconceptions.

Core Knowledge Points

1. Xiao Daocheng's Actual Status: Xiao Daocheng was the founder of the Southern Qi Dynasty. At the end of the Liu Song Dynasty, he commanded the imperial guard through military merit and held immense power over the court, but he did not form a so-called "system of four people taking turns ruling."
2. Core Staff Team: Xiao Daocheng did have a group of core advisors around him, such as Wang Jian, Wang Kun, and Xu Xiaosi. They participated in confidential matters, but they served as staff assistants, not as "Four Nobles" equal in status to Xiao Daocheng.
3. Truth of Power Transition: The process of the Liu Song Emperor Shun abdicating to Xiao Daocheng was the result of the concentration of power in Xiao Daocheng's hands, not a multi-person co-governance. The so-called "Four Nobles" might be a later misreading of the core members of Xiao Daocheng's early military group.

Connection with Zizhi Tongjian Content

Volumes 136 to 137 of Zizhi Tongjian record the political situation at the end of the Liu Song Dynasty in detail. The book records that Xiao Daocheng's prestige grew daily after pacifying the Sun En and Lu Xun rebellions. Especially during the Shengming era of Emperor Shun of Song, Xiao Daocheng held all power alone, eventually accepting the abdication and becoming emperor.

Sima Guang did not record a system of "Rule by Four Nobles" in the book. Instead, the book emphasizes that Xiao Daocheng's "authority grew daily," and other officials mostly attached themselves to him. For example, Wang Jian was drawn in by Xiao Daocheng as a confidant, responsible for rituals and statutes, but the decision-making power always rested solely with Xiao Daocheng. Referring to Xiao Daocheng's staff team as the "Four Nobles" easily causes confusion with the Eastern Han "Four Nobles" (imperial relatives and eunuchs) or the Ming Dynasty "Four Gentlemen."

Conclusion

"Rule by Four Nobles" is not a historical concept in Zizhi Tongjian. Xiao Daocheng's rise at the end of the Liu Song Dynasty is a typical pattern of a powerful minister usurping the throne, with the core lying in his personal military and political authority. When retrieving historical knowledge, one should rely on official historical records and avoid treating folk legends or misreadings as credible history. Understanding the real power structure helps to grasp the logic of political changes in the Southern Dynasties more accurately.
