八王の乱
Sima Lun (sim. ch. 司马伦, trad. ch. 司馬倫, py. sī mǎ lún, wg. Ssu-ma Lun) (poisoned June 5, 301), courtesy name Ziyi (子彛), was titled the Prince of Zhao (pinyin: zhào wáng, simplified Chinese: 赵王, traditional Chinese: 趙王) and the usurper of the Jin Dynasty from February 3 to May 30, 301. He is usually not counted in the list of Jin emperors due to his brief reign, and was often mentioned by historians as an example of a wicked usurper. He was the third of the eight princes commonly associated with the War of the Eight Princes.
