The Powerful Prime Minister at the End of the Southern Song Dynasty: Emperor Lizong of Song, Zhao Yunqi, and Political Turning Points in the Xu Zizhi Tongjian

Brief Introduction

Emperor Lizong of Song, Zhao Yunqi (1205–1264), was the fifth emperor of the Southern Song Dynasty. His temple name was Lizong, and his reign titles included Baoqing and Shaoding. During his reign, although the Southern Song experienced a brief period known as the "Revival of Shaoding" (Shao-ding Zhong-xing), the dynasty faced fierce internal factional struggles and deepening external threats. Court politics gradually became monopolized by the powerful chancellor Han Tongzhao. As a key figure marking the transition from prosperity to decline for the Southern Song, Emperor Lizong's rule is documented in detail in the Xu Zizhi Tongjian (Continued Comprehensive Mirror for Aid in Governance), the continuation of Sima Guang's Zizhi Tongjian. These records reflect the complexity and fragility of the political ecology in the late Southern Song period.

Core Knowledge Points

1. The Abolition of the Shaoding Faction and Han Tongzhao's Dominance
When Emperor Lizong first ascended the throne, he was young, and Empress Yang, together with the powerful chancellor Shi Miyuan, controlled the court politics. Shi Miyuan deposed Emperor Lizong and installed Prince Duan, Zhao Yun (who later became Emperor Ningzong). However, due to historical inconsistencies in the provided text regarding the sequence of emperors (Historically, it was Shi Miyuan who installed Emperor Ningzong and kept the rightful heir, later known as Lizong, in exile; the "Duan Zong" mentioned here seems to conflate different historical figures or is a specific narrative interpretation within the source text provided. Note: Standard history states that after Emperor Ningzong's death, Han Tongzhao helped restore the deposed Prince Zhao Yunqi to the throne as Emperor Lizong), the deposed emperor eventually regained his position. In the early phase of his restored rule, Emperor Lizong utilized Han Tongzhao's power to eliminate the opposition faction led by Empress Yang, a period historically referred to as "Han Tongzhao's Rise to Power." During this time, Han Tongzhao executed many court officials and suppressed public speech, leading to a drastic deterioration of the political atmosphere in the Southern Song.

2. The Lessons from the Failed Beixfa Campaign
Although the Beixfa (North Expedition) campaign primarily occurred during the reign of Emperor Gaozong/Kaizong (note: historically, the major Beixfa campaigns associated with Han Tongzhao were under Emperor Ningzong, not Kaizong, but the text provided places it under Kaizong's influence or legacy), Emperor Lizong's early reign was heavily influenced by its aftermath. The diplomatic strategy led by Han Tongzhao became increasingly aggressive but lacked the military strength to support it. Under pressure from the Jin Dynasty, they ultimately signed the "Jiadip Peace Treaty," which increased the financial burden on the Southern Song. This strategy of "softness on the outside and ruthlessness on the inside" failed to reverse the military disadvantage and instead intensified internal contradictions.

3. The Shaoding Censorship and Brain Drain
During the "Shaoding" era, although Emperor Lizong was nominally governing personally, he was actually constrained by powerful ministers. He failed to effectively purge the remnants of Han Tongzhao's faction. Instead, this led to the marginalization or exclusion of upright scholars such as Wu Cheng. This distortion in the talent selection mechanism laid the groundwork for the dual shortage of military generals and strategic advisors in the final years of the Southern Song.

4. The Brief Attempt of the Duanping Campaign
During the middle period of his reign, Emperor Lizong briefly attempted to take the initiative by supporting figures such as Deng Ai and Zheng Qingzhi to plan the "Duanping Campaign into Luoyang," with the intention of recovering the three capitals of Henan. Although this move temporarily boosted morale, it quickly turned into a disaster due to insufficient preparation and the collapse of logistics. The Jin army's counter-offensive forced the Southern Song to sign even harsher peace treaties. This marked the complete loss of strategic initiative by the Southern Song and its entry into the final defensive phase.

Connections to the Content of the Xu Zizhi Tongjian

The Xu Zizhi Tongjian was compiled by Bi Yuan in the Qing Dynasty, continuing Sima Guang's Zizhi Tongjian, which ended at the close of the Five Dynasties period. It covers historical events from the Song and Yuan dynasties. Regarding Emperor Lizong of Song, the book focuses on the following key turning points:

* The Process of Restoration: The book details how, following the sudden death of the previous emperor (referred to as "Duan Zong" in the source text, though historically complex), Emperor Lizong was quickly installed on the throne with the push of Han Tongzhao, revealing the power dynamics behind palace coups.
The Death of Han Tongzhao: The Xu Zizhi Tongjian* records the event where Han Tongzhao was executed on the scheme of Shi Miyuan during the reign of Emperor Ningzong of the Southern Song (Note: Clarification is needed here; historically, Han Tongzhao was executed in the 17th year of Jiading [1224] during Emperor Ningzong's reign, not while Lizong was on the throne. However, Lizong's restoration was directly benefiting from the political context of this event). After Emperor Lizong's accession, the book emphasizes how he balanced relationships with powerful chancellors such as Shi Miyuan and later Jia Sidao.
* The Duanping Peace Talks and War: The book has specific entries on the Jin-Song war in the "First Year of Duanping." It analyzes the consequences of Emperor Lizong's strategic miscalculations and records the historical fact that the Southern Song subsequently remained in a strategically passive position for a long period.

Through the records in the Xu Zizhi Tongjian, it can be seen that the period of Emperor Lizong of Song was a critical transition stage in Southern Song politics, moving from "Shi Miyuan's dictatorship" to "Jia Sidao's monopoly of power." Although Emperor Lizong personally had the desire to revitalize court governance, constrained by institutional flaws and his own abilities, he failed to save the Southern Song from its decline. The characteristics of his reign serve as a crucial case for understanding the preconditions of the Southern Song's fall.
