Sima Shi, born in the year two hundred eight, was a prominent military general and regent of the Cao Wei state during the tumultuous Three Kingdoms period of China. He was known by his courtesy name, Ziyuan, and played a pivotal role in the political landscape of his time.
In February of two hundred forty-nine, Sima Shi assisted his father, Sima Yi, in a significant coup that overthrew the regent Cao Shuang, thereby elevating the Sima family to a position of paramount authority within the state. Following his father's death in September of two hundred fifty-one, Sima Shi inherited this power and maintained a firm grip on the political scene.
His tenure was marked by strategic maneuvering, including the deposition of Emperor Cao Fang in two hundred fifty-four, who had contemplated taking action against him. Sima Shi replaced Cao Fang with his cousin, Cao Mao, further solidifying his control. His reign came to an end in March of two hundred fifty-five, shortly after he successfully quelled a rebellion.
Upon his death, Sima Shi transferred his power to his younger brother, Sima Zhao. This transfer of authority ultimately paved the way for Sima Yan, Sima Zhao's son, to usurp the throne and establish the Jin dynasty. In recognition of Sima Shi's significant contributions, Sima Yan posthumously honored him as Emperor Jing, with the temple name Shizong.
