Post-Zhou Taizu Guo Wei: The Cornerstone of the Five Dynasties Depicted in the Zizhi Tongjian

Brief Introduction
Guo Wei (904–954), courtesy name Wenzhong, was the founding emperor of the Later Zhou during the Five Dynasties and Ten Kingdoms period, with the temple name Taizu. Coming from a military background, he rose to prominence within the Later Han regime due to his outstanding military talents, eventually replacing it to establish the Later Zhou. During his reign, Guo Wei was dedicated to rectifying the administration and reducing taxes. He ended the frequent warfare characteristic of the Five Dynasties period and laid a solid foundation for the unification of the Northern Song Dynasty.

Core Knowledge Points
* Military Rise and Mutiny: Guo Wei was originally the Privy Councilor of the Later Han. Due to exclusion by powerful ministers and suspicion from the emperor, he was forced to rebel in Yedu (present-day Daming, Hebei). This event is historically known as the "Yedu Mutiny."
* Establishment of Later Zhou: In 951, Guo Wei led his army into Kaifeng, deposed the Yin Emperor of Later Han, and declared himself emperor. He changed the era name to Guangshun, named the state Zhou, and established the capital in Kaifeng.
* Governance Strategy: He advocated for frugality, abolished the harsh policies of the previous dynasty, and encouraged farming. He attempted to reverse the situation of military dominance and the suffering of the people during the Five Dynasties, placing emphasis on civil governance.
* Succession Arrangement: Guo Wei had no sons and adopted his son-in-law Chai Rong (who became Emperor Shizong of Later Zhou). Before his death, he clearly designated the succession, ensuring a smooth transition of power and avoiding internal strife.

*Connection to the Zizhi Tongjian***
In the Zizhi Tongjian, compiled by Sima Guang, Guo Wei's deeds are primarily concentrated in the Later Zhou records (Volumes 292–294). The book details the entire process of the "Yedu Mutiny," including how Guo Wei rose up under the pretext of "purging the emperor's side." It also records the detail that upon entering Kaifeng, he wore white mourning clothes, claiming to avenge the former emperor. This move significantly reduced political resistance.

Sima Guang particularly emphasized Guo Wei's "frugality" and "leniency." Compared to the extravagance and cruelty of other military emperors of the Five Dynasties, Guo Wei's lifestyle was simple, and he treated former ministers kindly. The Zizhi Tongjian demonstrates his political foresight through the records of his instructions to Chai Rong before his death. In his commentary, Sima Guang affirmed Guo Wei as a rare enlightened ruler among the Five Dynasties, believing his policies opened the path for Emperor Shizong's reforms and even the governance of the Northern Song. The narrative of Guo Wei in the book is not merely a personal biography but a political reflection on how the chaos of the Five Dynasties moved toward order, embodying Sima Guang's editorial purpose of "aiding governance" (Zizhi).

Historical Impact
Although Guo Wei reigned for only three years, the governance principles he established directly influenced the brilliant reforms of his successor, Emperor Shizong Chai Rong. As the last important emperor of the Five Dynasties, Guo Wei was a key hub in the transition from chaos to order. His historical status received an objective and positive evaluation in the Zizhi Tongjian, making him an indispensable core figure in the study of the Five Dynasties and Ten Kingdoms history.
