125 AD: The Accession of Emperor Shun of the Eastern Han and the Power Shift in "Zizhi Tongjian"

Brief Introduction

125 AD was a critical node in the history of the Eastern Han Dynasty. In this year, Emperor He (Liu Zhi) of Han passed away, and Emperor Shun (Liu Bao) ascended to the throne, marking the entry of the Eastern Han Dynasty into a new phase of rule. In historical chronology, 125 AD marks the beginning of the Yanguang era (Yanguang Year 1). Although some sources may contain chronological confusion, according to the records of the Book of the Later Han and the Zizhi Tongjian, 125 AD was indeed Yanguang Year 1, while Yanguang Year 4 corresponds to 128 AD. This article will focus on 125 AD, combining records from the Zizhi Tongjian, to analyze the historical context of this year.

Core Knowledge Points

* Key Figures: Emperor He (deceased), Emperor Shun (enthroned), Eunuchs such as Shan Chao and the "Five Marquises".
* Political Background: The decline of the Imperial Consort Kin Deng faction, the rise of the Eunuch Group, and intensified games between Imperial Power and Powerful Ministers.

Historical Context in "Zizhi Tongjian"

In the Zizhi Tongjian, the records of 125 AD focus on the power transition following the death of Emperor He. Sima Guang describes the process of Emperor Shun's accession in detail: Emperor He had no son, and his testamentary edict named Liu Bao, the son of Prince Qing of Qinghe (Liu Qing), to succeed him. However, this process was not smooth sailing; behind it lay a political transaction where eunuchs such as Shan Chao and Zuo Huang supported Emperor Shun in exchange for being made marquises.

The Zizhi Tongjian uses the events of this year to reveal the beginning of "Eunuch Tyranny" in the mid-Eastern Han period. The book records that after Emperor Shun's accession, he enfeoffed Shan Chao and four others as marquises, historically known as the "Five Marquises". In the narrative of the Zizhi Tongjian, this event is regarded as an important sign of the deterioration of the Eastern Han political ecology. Through this matter, Sima Guang warned future generations that if imperial power fell into the hands of eunuchs, it would plant the seeds of decline for the dynasty.

Additionally, the Zizhi Tongjian records sacrifices and edicts issued after Emperor Shun's accession in 125 AD, reflecting the new ruler's efforts to establish legitimacy through ritual systems. However, the book also implicitly expresses concerns about court politics being alternately dominated by eunuchs and Imperial Consort Kin (such as the Liang clan).

Historical Significance and Analysis

125 AD was not only a year of imperial succession but also a watershed moment for the transformation of the Eastern Han political structure.
1. Change in Power Structure: It marked the end of the era of the Imperial Consort Kin Deng and the beginning of the era of Eunuch interference in politics.
2. Era Name Clarification: It is important to note that 125 AD was Yanguang Year 1. If consulting the "Yanguang Year 4" entry in the Zizhi Tongjian, the corresponding year is actually 128 AD, which records further measures after Emperor Shun's personal rule and natural disasters.
3. Value of Historical Reflection: The Zizhi Tongjian's account of this year aims to clarify that "governance, chaos, rise, and fall" are closely related to personnel appointment, providing a profound political mirror for rulers of later generations.

By sorting out the context of 125 AD in the Zizhi Tongjian, we can not only clarify the details of era name chronology but also gain a deeper understanding of the internal logic of the Eastern Han Dynasty's transition from prosperity to decline.
