Overview
Sima Liang (司馬亮) (before 227- 26 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 Jin Dynasty (266–420). He was the first of the eight princes commonly associated with the War of the Eight Princes.
Life
Sima Liang was the fourth son of Sima Yi, by his concubine, Lady Fu; he was the eldest among Lady Fu's four sons. During the regencies within Cao Wei by his older half-brothers Sima Shi and Sima Zhao, he served as a mid-level official. After his nephew Sima Yan took the throne as Emperor Wu of Jin, ending Cao Wei and establishing Jin, Sima Liang was created the Prince of Fufeng on 9 February 266 and put in charge of the military commands of Qin (秦州, modern eastern Gansu) and Yong (雍州, modern central and northern Shaanxi) provinces. In 270, after his subordinate, the general Liu Qi (劉旂) was defeated by the Xianbei rebel Tufa Shujineng, Sima Liang tried to have Liu's life spared by claiming fault; Liu's life was spared, but Sima Liang lost his post as a result.
Despite this, Sima Liang was well respected among the Jin imperial clan for his virtues, including his filial devotion to Princess Dowager Fu. Because of this, Emperor Wu put him in charge of monitoring the imperial princes' behavior, to correct and rebuke them when necessary.
On 5 October 277, Emperor Wu moved Sima Liang's principality to Ru'nan and put him in charge of the military commands of Yu Province (豫州, modern eastern Henan). However, soon he recalled Sima Liang back to the capital to serve as a high-level advisor.
