'''Sima Lun''' ({{zh|first=t|s={{nowrap|司马伦}}|t=司馬倫|p=Sīmǎ Lún|w=Ssu-ma Lun}}) (born before 250<ref>While Sima Lun's birth year was not recorded, he was younger than his half-brothers [[Sima Gan]] and [[Sima Jun (prince)|Sima Jun]], who were born in 232.</ref> – [[poisoning|poisoned]] June 5, 301), [[courtesy name]] '''Ziyi''' ({{lang|zh|子彛}}), was titled the [[Prince]] of [[Principality of Zhao|Zhao]] ({{zh|labels=no|first=t|p=Zhào Wáng|s=赵王|t=趙王}}) and the usurper of the [[Jin dynasty (266–420)|Jin dynasty]] from February 3 to May 31, 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 usurper. He was the third of the eight princes commonly associated with the [[War of the Eight Princes]].

==Early career==
As [[Sima Yi]]'s ninth<ref>(赵王伦，字子彝，宣帝第九子也...) ''Jin Shu'', vol.59</ref> and youngest son, Sima Lun held a number of minor titles during the [[Cao Wei]] regencies of his father and half-brothers [[Sima Shi]] and [[Sima Zhao]]. Around February or March 250, he was enfeoffed as Marquis of Anle Village,<ref>(魏嘉平初，封安乐亭侯。) ''Jin Shu'', vol.59</ref><ref>([嘉平]二年春正月，...，封子肜平樂亭侯，倫安樂亭侯。) ''Jin Shu'', vol.01. The month corresponds to 19 Feb to 19 Mar 250 in the Julian calendar. This was about a year after the [[Incident at the Gaoping Tombs]].</ref> and when Sima Zhao established the Five Feudal Ranks of Zhou in 264, his fief was changed to Viscount of Dong'an, and he was designated Remonstrating and Consulting Grandee.<ref>(五等建，改封东安子，拜谏议大夫.) ''Jin Shu'', vol.59</ref>

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.<ref>According to Sima Yan's biography in ''Book of Jin'', he ascended the throne on the ''bingyin'' day of the 12th month of the 1st year of the ''Taishi'' era. This corresponds to 8 Feb 266 on the Julian calendar. On the ''dingmao'' day (i.e. the next day), he created Lun the Prince of Langye. (泰始元年冬十二月丙寅，设坛于南郊，...于是大赦，改元......丁卯,....伦为琅邪王...) ''Jin Shu'', vol. 03.</ref> 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,<ref>According to Sima Yan's biography in ''Book of Jin'', he moved Sima Lun's principality to Zhao on the ''guihai'' day of the 8th month of the 3rd year of the ''Xian'ning'' era. This corresponds to 5 Oct 277 on the Julian calendar. [(咸宁三年)八月癸亥，徙...，琅邪王伦为赵王...] ''Jin Shu'', vol.03</ref> his principality was moved to Zhao.

During the early reign of [[Emperor Hui of Jin|Emperor Hui]], on 19 September 291,<ref>([元康元年]八月庚申，以赵王伦为征东将军、都督徐兖二州诸军事；...) ''Jin Shu'', vol.04</ref> 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,<ref>([元康元年]九月...辛丑，...以赵王伦为征西大将军、都督雍梁二州诸军事。) ''Jin Shu'', vol.04</ref> Lun's post was changed; he was placed in charge of the military command of Qin (秦州, modern eastern [[Gansu]]) and Yong (雍州, modern central and northern [[Shaanxi]]) Provinces. During his tenure, his misgovernance contributed to conditions where the [[Di (Wu Hu)|Di]] and the [[Qiang (historical people)|Qiang]] rebelled under the Di chief [[Qi Wannian]] in 296. His chief strategist [[Sun Xiu (Jin dynasty)|Sun Xiu]] was arrested and initially set to be executed, but was spared by his half-brother [[Sima Rong]].  Sima Lun and Sun were recalled to the capital [[Luoyang]], where he flattered Empress Hui's empress [[Jia Nanfeng]] (who was then the ''de facto'' regent) and became trusted by her.  Lun then requested a high level office, but was rebuffed by Empress Jia's advisors [[Zhang Hua]] and [[Pei Wei (Jin dynasty)|Pei Wei]].

==As regent==
Empress Jia, in jealousy, deposed the [[crown prince]] [[Sima Yu]] (born not of her, but of her husband's [[concubine]] 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 the [[developmental disability|developmentally 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 of [[Taishang Huang|retired emperor]] but putting him under house arrest.  Emperor Hui's grandson, the crown prince Sima Zang (司馬臧), was executed.

==As emperor==
[[File:Uprising of the Three Princes.png|thumb|300x300px|Uprising of the Three Princes, 301 AD.]]
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 Qi [[Sima You]]), [[Sima Ying]] the Prince of Chengdu (Emperor Hui's half-brother), and [[Sima Yong]] the Prince of Hejian (the grandson of Emperor Hui's great-granduncle [[Sima 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), and [[Sima Xin (Hongshu)|Sima Xin]] (司馬歆) the Duke of Xinye (the son of a granduncle of Emperor Hui, [[Sima Jun (prince)|Sima Jun]]) all declared support for Prince Jiong.  Prince Yong initially sent his general [[Zhang 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".
