Sima Fu
Sima Fu's second brother, Sima Yi, rose to power in the state of Cao Wei during the Three Kingdoms period (220–280) and became the regent and "de facto" ruler of Wei after seizing power in a "coup d'état" in 249. After Sima Yi's death, his sons Sima Shi and Sima Zhao consecutively succeeded him as the regent and "de facto" ruler of Wei. During his service under the Wei regime, Sima Fu held relatively high offices: Prefect of the Masters of Writing (尚書令) during the reign of Cao Rui; and Grand Commandant (太尉) and Grand Tutor (太傅) during the reigns of Cao Fang, Cao Mao and Cao Huan. He also served as a military commander in some battles against Wei's rival states, Shu Han and Eastern Wu. In 266, Sima Zhao's son Sima Yan forced the last Wei emperor Cao Huan to abdicate the throne in his favour, thereby ending the Wei regime. Sima Yan established the Jin dynasty and became its first emperor.
