About Sima Yi
- Sima Yi (pronunciation Chinese: ???; 179 – 7 September 251), courtesy name Zhongda, was a Chinese military general, politician, and regent of the state of Wei during the Three Kingdoms period of China.
- He formally began his political career in 208 under the Han dynasty's Imperial Chancellor Cao Cao; quickly rising through the ranks.
- His success in both handling domestic and military affairs, such as in governance and the promotion of agriculture, serving as a capable adviser, repelling incursions and invasions led by Shu and Wu forces, speedily crushing Meng Da's rebellion, and conquering the Gongsun-led Liaodong commandery, all managed to garner him great prestige over the decades.
- He is perhaps best known for defending Wei from a series of invasions between 231 and 234 led by Wei's rival state Shu.
- In 239, he was made to preside as a regent for the young Cao Fang—after the latter's adoptive father, Cao Rui, had died—along with another co-regent, Cao Shuang.
- Although amicable at first, the relationship soon deteriorated in light of Cao Shuang's corruption, extravagance, and attempts to curtail Sima Yi's political influence.
- In 249, after carefully planning and building up support, he ousted Cao Shuang from power in a coup d'Ă©tat and had him and his associates executed.Sima Yi would go on to serve as the de facto primary authority in Wei after this event, although in 251 he faced some opposition in the form of Wang Ling's rebellion, which he swiftly dealt with.
- He died later that year, on 7 September 251, at the age of 71 or (more likely) 72, with his eldest son, Sima Shi, succeeding his position.For the remainder of Wei's history, state power would increasingly rest in the hands of the Sima clan, which paved the way for the establishment of the Jin dynasty, which was founded by Sima Yi's grandson, Sima Yan, in 266.
- After Sima Yan became emperor, he honoured his grandfather with the posthumous title Emperor Xuan of Jin (???) and the temple name Gaozu (??).
