Sima Wei

Sima Wei (司馬瑋) (271 – 26 July 291), courtesy name Yandu (彥度), formally Prince Yin of Chu (楚隱王), was an imperial prince during the Western Jin dynasty and was the second of the eight princes commonly associated with the War of the Eight Princes. The half-brother of Emperor Hui of Jin, Sima Wei aligned himself with Empress Jia to overthrow the overbearing regent, Yang Jun and his family. His granduncle, Sima Liang and the minister, Wei Guan were installed to take over the regency, but Sima Wei soon became dissatisfied by their attempts to strip him of his military power. He allied with Empress Jia once more, and, after forging an imperial edict which placed him virtually in command of the empire's military, he had the two regents arrested and killed. However, Empress Jia betrayed him by accusing him of treason, and just a day later, he too was apprehended and executed.
