Sima You became the heir to his uncle, Sima Shi, who eventually died without any sons. It is known that Sima You was a person of mild-mannered character, who was expected to become King of Jin, but ended up being passed over due to his young age. The heir that was eventually chosen was Sima Zhao's first son, Sima Yan (Emperor Wu), who usurped the Cao Wei throne and established the Jin dynasty with himself as the new emperor in February 266. Sima You was made Prince of Qi on 9 February 266.[3]

When Emperor Wu appointed his developmentally disabled son heir apparent, he was concerned that his subjects viewed Sima You too favourably. In order to strengthen his son's position, he ordered Sima You away from Luoyang in 282 to his fiefdom of Qi, despite protestations from their sisters, Princess Jingzhao and Princess Changshan.[4] Sima You fell ill from the stress and died soon after at the age of 36 (by East Asian age reckoning).[5]

Sima You's son, Sima Jiong, was one of the eight princes involved in the War of the Eight Princes during the reign of Emperor Hui, the second emperor of the Jin dynasty.

  1. ^ Although Sima You's biography in Book of Jin indicated that he was 36 (by East Asian reckoning) when he died, his biography also indicated that he was 10 (by East Asian reckoning) when Sima Shi died (in March 255). In addition, his biography also indicated that he was older than 18 (by East Asian reckoning) when the "five-rank peerage" system was reinstated (in 264), which would not be the case if his birth year is 248. Thus, his age at death should be greater than 36 (by East Asian reckoning).
