Biography & Historical Record
Sima Fu (180–272 AD), courtesy name Shuda, was a prominent statesman, scholar, and imperial official of Cao Wei during the Three Kingdoms period, who later lived into the early Jin dynasty. Born in Wen County, Henei Commandery (present-day Wen County, Henan), he was the third son of Sima Fang and the younger brother of the renowned strategist Sima Yi. Known for his mild temperament, literary talent, and unwavering personal integrity, Sima Fu served successive rulers of Cao Wei with utmost loyalty, holding numerous high-ranking civil and military posts including Minister of Works and Grand Tutor.
Despite his family holding absolute de facto control over the state of Cao Wei, Sima Fu maintained a deeply conservative loyalty to the imperial Cao clan throughout his long life. When his nephew Sima Zhao and great-nephew Sima Yan ultimately forced the abdication of the Wei emperors, Sima Fu wept openly at the palace gates and famously declared that until his dying breath, he would remain a loyal subject of Cao Wei. Out of profound respect for his virtue and seniority, the Sima rulers never persecuted him. He passed away in 272 AD at the advanced age of ninety-three, universally respected across the realm for his moral steadfastness.
Role in Romance of the Three Kingdoms
In Luo Guanzhong’s epic novel Romance of the Three Kingdoms, Sima Fu is portrayed as an intelligent, prudent, and deeply principled statesman who acts as the moral conscience within the powerful Sima family. Introduced during the political maneuvers of Cao Wei, Sima Fu assists his brother Sima Yi in managing domestic affairs and executing state security. In Chapter 106, during the Gaoping Tombs Incident, Sima Fu acts alongside Sima Yi to secure the capital of Luoyang against Cao Shuang’s faction.
However, Sima Fu’s defining literary moments highlight his loyalty to the declining imperial house. In Chapter 114, following the tragic assassination of the young Wei emperor Cao Mao by Cheng Ji, Sima Fu rushes to the scene, cradles the emperor’s body in his lap, and weeps bitterly, openly rebuking the brutal violence committed by his family’s associates. Even after the founding of the Jin dynasty, Sima Fu refuses to accept high imperial honors as a Jin prince, maintaining his identity as a loyal official of Wei until his death.
