Sima Liang

Sima Liang (司馬亮) (before 227 - 25 July 291), courtesy name Ziyi (子翼), formally Prince Wencheng of Ru'nan (汝南文成王), was briefly a regent during the reign of Emperor Hui during the Western Jin dynasty. He was the first of the eight princes commonly associated with the War of the Eight Princes. A son of Sima Yi, he was entrusted by his nephew, Emperor Wu of Jin to act as regent for the developmentally disabled Emperor Hui. Though he was initially excluded from the regency due to interference from his co-regent Yang Jun, he was later installed alongside the minister, Wei Guan in May 291 after Empress Jia Nanfeng led a coup against Yang Jun in April that year. His short regency in Luoyang was marked by his dispute with the Prince of Chu, Sima Wei. In July 291, Sima Wei allied himself with Empress Jia and falsely charged Sima Liang and Wei Guan of plotting against the imperial family, after which they were both executed.
