Sun Jun

Sun Jun is a senior figure in Wu whose decisive appearance comes in the struggle over Zhuge Ke’s power. He helps arrange Zhuge Ke’s assassination at a banquet, then receives authority from the emperor, a shift that places him at the center of Wu’s court politics and foreshadows the later dominance of his cousin Sun Chen.

Position in Wu Politics

The book identifies Sun Quan as one of the three leaders whose kingdoms emerged from the collapse of the Han. Sun Jun belongs to the later Wu court, where authority is contested within the ruling family and through control of the emperor. His actions in the episode surrounding Zhuge Ke mark him as a participant in that internal struggle rather than as a battlefield commander.

The Plot Against Zhuge Ke

After a disastrous campaign against Wei, Zhuge Ke withdraws from public view and feigns illness. His military failure, resentment toward him, and abuse of power give members of the Sun family grounds to conspire against him. Sun Jun petitions the emperor for permission to execute Zhuge Ke, and the court arranges to lure him to a banquet, where the emperor’s longstanding wish to remove him can be carried out.

The plan turns on a signal. At the banquet, Sun Jun announces that the Son of Heaven has ordered a traitor’s execution and kills Zhuge Ke. Zhuge Ke’s brother Zhang Yue is also killed. The bodies are disposed of without marked graves, making the removal both a political execution and a deliberate erasure of its victims from public commemoration.

Authority and Aftermath

The killing brings Sun Jun immediate political advancement: from that day, the emperor gives power to him. The narrative links this transfer of authority directly to Zhuge Ke’s removal, showing how a court conspiracy converts violence into control of government. Sun Jun’s elevation is not presented as a lasting resolution of Wu’s instability; rather, it precedes another transfer of power within the same family.

Succession and Narrative Role

When Zhuge Dan later appeals to Wu for help against Sima Zhao, the account identifies Sun Jun as prime minister. By then he has died, and his cousin Sun Chen has taken over, described as cruel and tyrannical, while Emperor Sun Liang is unable to control him. Sun Chen nevertheless responds to Zhuge Dan’s appeal by sending seventy thousand troops. Sun Jun’s brief rise thus forms one link in a continuing succession of court power struggles: his own authority follows Zhuge Ke’s assassination, and after his death it passes to a relative whose rule further diminishes the emperor’s ability to govern.
