Sima Lun (traditional Chinese:司馬倫;simplified Chinese:司马伦;pinyin:Sīmǎ Lún;Wade–Giles:Ssu-ma Lun) (born before 250[7] –poisoned 5 June 301),courtesy nameZiyi (子彛), was titled thePrince ofZhao (趙王;赵王;Zhào Wáng) and the usurper of theJin dynasty from 3 February to 31 May 301. He is usually not counted in the list of Jin emperors due to his brief reign and was often mentioned by historians as a usurper. He was the third of the eight princes commonly associated with theWar of the Eight Princes.
A son ofSima Yi, Sima Lun was arguably the most reviled and hated among the Eight Princes. His tenure as governor in theGuanzhong region ended in alarge-scale rebellion by the local tribes which forced him to be recalled back to the capital,Luoyang in 296. Back in the capital, he became a confidant ofEmpress Jia and her family, who ruled the empire behind the throne of her husband and Sima Lun's grandnephew,Emperor Hui. As she lost support due to her controversial removal of the Crown Prince,Sima Yu, Sima Lun led a coup to depose her and installed himself as the emperor's new regent. Sima Lun, with the help of his advisor,Sun Xiu had all his court rivals brutally purged and eventually compelled Emperor Hui to abdicate the throne to him in 301. His usurpation was immediately denounced, and just a few months later, he was defeated by the coalition of the "Three Princes" (Sima Jiong,Sima Ying andSima Yong) and forced to commit suicide.
Though Sima Lun was overthrown, his usurpation was the beginning of a more destructive chapter in the War of the Eight Princes. No longer confined within the walls of Luoyang, the conflict had escalated into a series of full-blown civil wars that would devastate northern China for years to come.
AsSima Yi's ninth[8] and youngest son, Sima Lun held a number of minor titles during theCao Wei regencies of his father and half-brothersSima Shi andSima Zhao. Around February or March 250, he was enfeoffed as Marquis of Anle Village,[9][10] and when Sima Zhao established theFive Feudal Ranks of Zhou in 264, his fief was changed to Viscount of Dong'an, and he was designated Remonstrating and Consulting Grandee.[11]
After his nephew Sima Yan established the Jin dynasty on 8 February 266, Sima Lun was named the Prince of Langye Commandery the next day.[12] He served as a general and governor at times during his nephew's reign, but was undistinguished; several times he was accused of crimes, such as when sending Cavalier Commander Liu Ji to pay laborers wanting to rob imperial furs, but each time Emperor Wu pardoned him of them. On 5 October 277,[13] his principality was moved to Zhao.
During the early reign ofEmperor Hui, on 19 September 291,[14] Sima Lun was placed in charge of the military command of Xu (徐州) and Yan (兖州) Provinces. About a month later, on 30 October,[15] Lun's post was changed; he was placed in charge of the military command of Qin (秦州, modern easternGansu) and Yong (雍州, modern central and northernShaanxi) Provinces. During his tenure, his misgovernance contributed to conditions where theDi and theQiang rebelled under the Di chiefQi Wannian in 296. His chief strategistSun Xiu was arrested and initially set to be executed, but was spared by his half-brotherSima Rong. Sima Lun and Sun were recalled to the capitalLuoyang, where he flattered Empress Hui's empressJia Nanfeng (who was then thede facto regent) and became trusted by her. Lun then requested a high level office, but was rebuffed by Empress Jia's advisorsZhang Hua andPei Wei.
Empress Jia, in jealousy, deposed thecrown princeSima Yu (born not of her, but of her husband'sconcubine Consort Xie Jiu) in February 300. Later, there was a conspiracy to overthrow her and restore the crown prince. Sima Lun was persuaded to join the conspiracy, but Sun Xiu had another plan for him: he should encourage Empress Jia to assassinate the crown prince in exile, and then use the assassination as the excuse to overthrow her. Sima Lun accepted this plan and persuaded her to assassinate the crown prince, which she did in April 300. He then declared a coup against her in May and arrested her, slaughtering her clan and her associates (including Zhang and Pei). He then forced her to commit suicide.
Sima Lun then became regent for thedevelopmentally disabled Emperor Hui, but was described as being not particularly more intelligent than Emperor Hui. Even though he carried the regent title, true power was in Sun Xiu's hands. Under Sun Xiu's persuasion, he deposed Emperor Hui and declared himself emperor in February 301, offering Emperor Hui the honorific title ofretired emperor but putting him under house arrest. Emperor Hui's grandson, the crown prince Sima Zang (司馬臧), was executed.
The act of usurpation brought widespread anger. In order to appease those who might be angry at his usurpation, Sima Lun rewarded many people with honors. Sun, in particular, was issuing edicts based on his own whims. Suspecting three autonomous key princes—Sima Jiong the Prince of Qi (Emperor Hui's cousin and the son of Emperor Hui's uncle, Prince Xian of QiSima You),Sima Ying the Prince of Chengdu (Emperor Hui's half-brother), andSima Yong the Prince of Hejian (the grandson of Emperor Hui's great-granduncleSima Fu, Prince Xian of Anping), each of whom had strong independent military commands—Sun sent his trusted subordinates to be their assistants. Prince Jiong refused and declared a rebellion to restore Emperor Hui. Prince Ying,Sima Ai the Prince of Changshan (Emperor Hui's half-brother), andSima Xin (司馬歆) the Duke of Xinye (the son of a granduncle of Emperor Hui,Sima Jun) all declared support for Prince Jiong. Prince Yong initially sent his generalZhang Fang (張方) with intent to support Sima Lun, but then heard that Princes Jiong and Ying had great forces, and so declared for the rebels instead. Sima Lun's forces were easily defeated by Princes Jiong's and Ying's forces, and after declaring himself emperor for three months, Sima Lun was captured by officials in Luoyang who declared for the rebellion as well and forced him to issue an edict returning the throne to Emperor Hui. Sima Lun was then forced to commit suicide. Sun and other associates of Sima Lun were executed, as were all of Sima Lun's sons. Sima Lun was posthumously demoted to commoner rank as "Commoner Zhao".
