Sima Liang (simplified: 司馬亮, traditional: 司馬亮, pinyin: Sīmǎ Liàng), courtesy name Ziyi (子翼), was Sima Yi’s third son (eldest of Lady Fu’s four sons). Under the Jin dynasty founded by his nephew Sima Yan (Emperor Wu), he was enfeoffed as Prince of Fufeng (266) and later Prince of Runan (汝南王). After Emperor Wu’s death (290), Emperor Hui (Sima Zhong) succeeded; Sima Liang was recalled to the capital and briefly served as regent in 291. Rival princes and the empress’s faction spread accusations that he was plotting against the court; he was driven out and executed that same year. His death is part of the turmoil leading to the War of the Eight Princes. He is remembered as a senior prince who tried to stabilise the court but fell victim to factional intrigue.
