Biography & Historical Record
Sima Dingguo (司马定国, 司馬定國, Tư Mã Định Quốc; c. 250s–c. 260s AD) was an imperial prince of Western Jin, born to King Wen of Jin Sima Zhao (司马昭) and his primary consort, the revered Wang Yuanji (王元姬). He was the full biological brother of founding Emperor Wu Sima Yan (司马炎) and Prince of Qi Sima You (司马攸).
Endowed with extraordinary infant charm, Sima Dingguo tragically succumbed to childhood illness at merely three years of age, deeply grieving Sima Zhao and Wang Yuanji. Following the founding of the Jin dynasty in 265 AD, Emperor Wu issued an imperial decree posthumously elevating his deceased brother as Prince Daohui of Liaodong (辽东悼惠王), decreeing Sima You’s son Sima Tuo to inherit the princely lineage.
