'''Emperor Wu of Jin''' ({{zh|s=晋武帝|t=晉武帝|p=Jìn Wǔ Dì|w=Chin Wu-Ti|c=}}; 236 – 16 May 290<ref>According to Sima Yan's biography in ''Book of Jin'', he died aged 55 (by East Asian reckoning) on the ''jiyou'' day of the 4th month of the 1st year of the ''Taixi'' era of his reign. This corresponds to 16 May 290 on the proleptic Gregorian calendar. By calculation, his birth year should be 236. ([太熙元年四月]己酉，帝崩于含章殿，时年五十五...) ''Jin Shu'', vol. 03</ref>), personal name '''Sima Yan''' ({{zh|t=司馬炎|p=Sīmǎ Yán}}), [[courtesy name]] '''Anshi''' (安世), was a grandson of [[Sima Yi]], nephew of [[Sima Shi]] and son of [[Sima Zhao]]. He became the first emperor of the [[Jin dynasty (266–420)|Jin dynasty]] after forcing [[Cao Huan]], last [[Emperor of China|emperor]] of the state of [[Cao Wei]], to abdicate to him.  He reigned from 266 to 290, and after [[Conquest of Wu by Jin|conquering]] the state of [[Eastern Wu]] in 280, was the emperor of a reunified China. Emperor Wu was also known for his extravagance and sensuality, especially after the unification of China; legends boasted of his incredible potency among ten thousand concubines.

Emperor Wu was commonly viewed as generous and kind, but also wasteful. His generosity and kindness undermined his rule, as he became overly tolerant of the noble families' (世族 or 士族, a political/bureaucratic landlord class from [[Eastern han|Eastern Han]] to [[Tang dynasty]]) corruption and wastefulness, which drained the people's resources. Further, when Emperor Wu established the Jin Dynasty, he was concerned about his regime's stability, and, believing that the predecessor state, Cao Wei, had been doomed by its failures to empower the princes of the [[Sima (Chinese surname)|imperial clan]], he greatly empowered his uncles, his cousins, and his sons with authority, including independent military authority. This ironically led to the destabilization of the Western Jin, as the princes engaged in an internecine struggle known as the [[War of the Eight Princes]] soon after his death, and then the "[[Five Barbarians]]" uprisings that [[Upheaval of the Five Barbarians|destroyed]] the Western Jin and forced its successor, Eastern Jin, to relocate to the region south of the [[Huai River]].

==Life under Cao Wei==
Sima Yan was born to [[Sima Zhao]] and his wife [[Wang Yuanji]], daughter of the [[Confucian]] scholar [[Wang Su (Cao Wei)|Wang Su]], in 236, as their oldest son. At that time, Sima Zhao was a mid-level official in the government of Cao Wei and a member of a privileged clan, as the son of the general [[Sima Yi]]. After Sima Yi seized power from the regent [[Cao Shuang]] in February 249 in the [[Incident at the Gaoping Tombs]], Sima Zhao became more influential in the state. After his father's death in September 251, Sima Zhao became the assistant to his brother, the new regent [[Sima Shi]]. After Sima Shi died in March 255, Sima Zhao became regent and the paramount authority in the Wei government.

Sima Yan's first important appearance in history was in 260, when forces loyal to his father, led by [[Jia Chong]], defeated [[Sima Zhao's regicide of Cao Mao|an attempt]] by the Wei emperor [[Cao Mao]] to take back power and killed Cao Mao. At that time, as a mid-level army general, he was commissioned by his father to escort the new emperor [[Cao Huan]] (then still known as Cao Huang) from his dukedom to the capital [[Luoyang]]; Sima Yan went to Ye to receive Cao.<ref>(使中护军司马炎迎燕王宇之子常道乡公璜于邺，以为明帝嗣。炎，昭之子也。) ''[[Zizhi Tongjian]]'', vol.77. The Military Protector of the Palace can order troops within palace grounds, and is of significance to the Sima clan; during the [[Incident at the Gaoping Tombs]], Yan's uncle [[Sima Shi]] was in this post.</ref> After his father was created the Duke of Jin on 9 December 263 in light of the army's conquest of [[Shu Han]], he was named heir. However, at times Sima Zhao hesitated as to whether Sima Yan or his brother [[Sima You]] would be the more appropriate heir—as Sima You was considered talented and had also been adopted by Sima Shi, who had no biological sons of his own, and Sima Zhao, remembering his brother's role in the Simas' takeover of power, thought it might be appropriate to return power to his branch of the clan. However, a number of high level officials favored Sima Yan, and Sima Zhao agreed. After Sima Zhao was created the King of Jin on 2 May 264 (thus reaching the penultimate step towards usurpation), Sima Yan was created the Crown Prince of Jin in June 265.<ref><br>{{quote|Jin shu, Chronicle of Wudi states: "In the second year of Xianxi, in the fifth month, Sima Yan was appointed Crown Prince of Jin.
Chronicles of the Three Kingdoms, Achilles Fang.}}</ref><ref>The month corresponds to 1 to 30 Jun 265 in the Julian calendar. However, vol. 78 of ''Zizhi Tongjian'' indicated that Sima Yan was made heir (世子) on the ''bing'wu'' day of the 10th month of the 1st year of the ''Xian'xi'' era, which corresponds to 25 Nov 264 in the Julian calendar.</ref>

On 6 September 265, Sima Zhao died without having formally taken imperial authority. Sima Yan became the King of Jin by the next day. On 4 February 266, he forced Cao Huan to abdicate, ending the state of Cao Wei. Four days later, on 8 February 266, he declared himself emperor of the Jin dynasty.

==As Emperor of Jin==

===Early reign: establishment of the Jin political system===
Emperor Wu immediately sought to avoid what he saw as Cao Wei's fatal weakness—lack of power among the imperial princes. In February 266, immediately after taking the throne, he made princes of many of his uncles, cousins, brothers, and sons, each with independent military commands and full authority within their principalities. This system, while it would be scaled back after the [[War of the Eight Princes]] and the loss of northern China, would remain in place as a Jin institution for the duration of the dynasty's existence, and would be adopted by the succeeding [[Southern dynasties]] as well.

Another problem that Emperor Wu saw with Cao Wei's political system was its harshness in penal law, and he sought to reform the penal system to make it more merciful—but the key beneficiaries of his changes turned out to be the nobles, as it quickly became clear that the mercy was being dealt out in an unequal manner. Nobles who committed crimes often received simple rebukes, while there were no meaningful reductions in penalties for commoners. This led to massive corruption and extravagant living by the nobles, while the poor went without government assistance. For example, in 267, when several high level officials were found to have worked in conjunction with a county magistrate to seize public land for themselves, Emperor Wu refused to punish the high level officials while punishing the county magistrate harshly.

Emperor Wu faced two major military issues almost immediately—incessant harassment from the rival [[Eastern Wu]]'s forces, under emperor [[Sun Hao]], and tribal rebellions in Qin (秦) and Liang (涼) provinces (modern [[Gansu]]). Most officials were more concerned about the [[Xianbei]], [[Qiang (historical people)|Qiang]] and other tribes in northwestern China and also with the [[Xiongnu]] in modern [[Shanxi]], who were resettled there after the dissolution of their state by [[Cao Cao]] in 216 under the watchful eyes of Chinese officials, and were feared for their military abilities. These officials advised Emperor Wu to try to suppress the tribes before considering conquests of Eastern Wu. Under the encouragement of the generals [[Yang Hu]] and [[Wang Jun (Jin dynasty)|Wang Jun]] and the strategist [[Zhang Hua]], however, Emperor Wu, while sending a number of generals to combat the tribes, prepared the southern and eastern border regions for war against Eastern Wu throughout this part of his reign.  He was particularly encouraged by reports of Sun Hao's cruelty and ineptitude in governing Eastern Wu; indeed, the officials in favor of war against Eastern Wu often cited this as reason to act quickly, as they argued that Eastern Wu would be harder to conquer if and when Sun Hao was replaced. However, after a [[Tufa Shujineng's Rebellion|major revolt]] by the Xianbei chief [[Tufa Shujineng]] started in 270 in Qin Province, Emperor Wu's attention became concentrated on Tufa, as Tufa was able to win victory after victory over Jin generals. In 271, the Xiongnu noble [[Liu Meng (Xiongnu)|Liu Meng]] rebelled in [[Bingzhou|Bing province]] as well, and while his rebellion did not last long, this took Emperor Wu's attention away from Eastern Wu. In 271, Jiao Province (交州, modern northern [[Vietnam]]), which had paid allegiance to Jin ever since the start of his reign, was [[Jiao Province Campaign|recaptured by Eastern Wu]]. In 272, the Eastern Wu general [[Bu Zhi#Descendants|Bu Chan]], in fear that Sun Hao was going to punish him on the basis of false reports against him, tried to [[Battle of Xiling|surrender the important city of Xiling]] (西陵, in modern [[Yichang]], [[Hubei]]) to Jin, but Jin relief forces were stopped by the Eastern Wu general [[Lu Kang (Three Kingdoms)|Lu Kang]], who then recaptured Xiling and killed Bu. In light of these failures, Yang took another tack—he started a [[détente]] with Lu and treated the Eastern Wu border residents well, causing them to view Jin favorably.

When Emperor Wu ascended the throne in February 266, he honored his mother Wang Yuanji as empress dowager. In 266, he also honored his aunt [[Yang Huiyu]] ([[Sima Shi]]'s wife) an empress dowager, in recognition of his uncle's contributions to the establishment of the Jìn Dynasty.  He made his wife [[Empress Yang Yan|Yang Yan]] empress the same year.  In 267, he made her oldest living son, [[Emperor Hui of Jin|Sima Zhong]] crown prince—based on the Confucian principle that the oldest son by an emperor's wife should inherit the throne—a selection that would, however, eventually contribute greatly to political instability and the Jin Dynasty's decline, as Crown Prince Zhong appeared to be developmentally disabled and unable to learn the important skills necessary to govern. Emperor Wu further made perhaps a particularly fateful choice on Crown Prince Zhong's behalf—in 272, he selected [[Empress Jia Nanfeng|Jia Nanfeng]], the strong-willed daughter of the noble [[Jia Chong]], to be Crown Prince Zhong's princess.  Crown Princess Jia would, from that point on, have the crown prince under her own tight control. Before Empress Yang died in 274, she was concerned that whoever the new empress would be, she would have ambitions to replace the crown prince, and therefore Empress Yang asked Emperor Wu to marry her cousin [[Empress Yang Zhi|Yang Zhi]]. He agreed.

In 273, Emperor Wu would undertake a selection of beautiful women from throughout the empire—a warning sign of what would eventually come. He looked most attentively at the daughters of high officials, but he also ordered that no marriages take place across the empire until the selection process was done.

===Middle reign: unification of the Chinese empire===
In 276, Emperor Wu suffered a major illness—which led to a succession crisis. Crown Prince Zhong would be the legitimate heir, but both the officials and the people hoped that Emperor Wu's capable brother, Sima You, the Prince of Qi, would inherit the throne instead. After Emperor Wu became well, he divested some military commands from officials that he thought favored Prince You, but otherwise took no other punitive actions against anyone.

Later that year, Yang Hu reminded Emperor Wu of his plan to conquer Eastern Wu. Most of the officials, still concerned with Tufa's rebellion, were opposed, but Yang was supported by [[Du Yu]] and Zhang. Emperor Wu considered their counsel seriously but did not implement it at this time.

Also in 276, pursuant to his promise to the deceased Empress Yang, Emperor Wu married his cousin Yang Zhi and made her empress. The new Empress Yang's father, [[Yang Jun (3rd century)|Yang Jun]], became a key official in the administration and became exceedingly arrogant.

In 279, with the general [[Ma Long (Jin dynasty)|Ma Long]] having finally put down Tufa's rebellion, Emperor Wu concentrated his efforts on Eastern Wu, and commissioned a six-pronged attack led by his uncle [[Sima Zhou]], [[Wang Hun (general)|Wang Hun]], [[Wang Rong (Jin dynasty)|Wang Rong]], [[Hu Fen]] (胡奮), Du Yu, and [[Wang Jun (Jin dynasty)|Wang Jun]], with the largest forces under Wang Hun and Wang Jun. Each of the Jin forces advanced quickly and captured the border cities that they were targeting, with Wang Jun's fleet heading east down the Yangtze and clearing the river of Eastern Wu fleets. The Eastern Wu chancellor [[Zhang Ti]] (張悌) made a last-ditch attempt to defeat Wang Hun's force, but was defeated and killed. Wang Hun, Wang Jun, and Sima Zhou each headed for Jianye, and Sun Hao was forced to surrender in spring 280.  Emperor Wǔ made Sun Hao the Marquess of Guiming.  The integration of former Eastern Wu territory into Jin appeared to have been a relatively smooth process.

After the fall of Eastern Wu, Emperor Wu ordered that provincial governors no longer be in charge of military matters and become purely civilian governors, and that regional militias be disbanded, despite opposition by the general [[Tao Huang (general)|Tao Huang]] and the key official [[Shan Tao (Taoist)|Shan Tao]]. This would also eventually prove to create problems later on during the [[upheaval of the Five Barbarians]], as the regional governors were not able to raise troops to resist quickly enough. He also rejected advice to have the non-Han gradually moved outside of the empire proper.

===Late reign: setting the stage for disasters===
In 281, Emperor Wu took 5,000 women from Sun Hao's palace into his own, and thereafter became even more concentrated on feasting and enjoying the women, rather than on important matters of state. It was said that there were so many beautiful women in the palace that he did not know whom he should have sexual relations with; he therefore rode on a small cart drawn by goats, and wherever the goats would stop, he would stop there, as well.<ref>{{cite book |last1=上海博物館 |title=華容世貌: 上海博物館藏明清人物畫 |date=2001 |publisher=Xianggang da xue mei shu guan |isbn=9789628038343 |page=66 |access-date=30 September 2020|url=https://books.google.com/books?id=k6RHAQAAIAAJ&q=wu+cart+goats+bamboo}}</ref> Because of this, many of the women planted bamboo leaves and salt outside their bedrooms—both items said to be favored by goats. Empress Yang's father Yang Jun and uncles Yang Yao (楊珧) and Yang Ji (楊濟) became effectively in power.

Emperor Wu also became more concerned about whether his brother Prince You would seize the throne if he died. In January 283, he sent Prince You to his principality, even though there was no evidence that Prince You had such ambitions. Princess Jingzhao and [[Princess Changshan]] [[kow-tow]]ed and begged Emperor Wu to rescind his order, but he merely grew angry and demoted [[Princess Changshan]]'s husband in retaliation.<ref>{{cite book| chapter=列传第十二 | trans-chapter=Biography 12 | title=晉書 | trans-title=Book of Jin | language=zh | editor1=Fang Xuanling | editor-link=Fang Xuanling

Following previous [[Sino-Roman relations|Roman embassies]] in 166 and 226, the ''[[Book of Jin]]'' and ''[[Wenxian Tongkao]]'' record another embassy from "[[Da Qin]]" appearing in China during the reign of Emperor Wu. These histories assert that it arrived in 284 and presented tributary gifts to the emperor.<ref>Warwick Ball (2016), ''Rome in the East: Transformation of an Empire'', 2nd edition, London & New York: Routledge, {{ISBN|978-0-415-72078-6}}, p. 152.</ref><ref name="halsall 2000">{{cite web|orig-year=1885|date=2000|author=Friedrich Hirth|editor=Jerome S.

As Emperor Wu grew ill in 289, he considered whom to make regent. He considered both Yang Jun and his uncle [[Sima Liang]] the Prince of Ru'nan, the most respected of the imperial princes. As a result, Yang Jun became fearful of Sima Liang and had him posted to the key city of [[Xuchang]]. Several other imperial princes were also posted to other key cities in the empire. By 290, Emperor Wu resolved to let Yang and Sima Liang both be regents, but after he wrote his will, the will was seized by Yang Jun, who instead had another will promulgated in which Yang alone was named regent. Emperor Wu died soon thereafter, leaving the empire in the hands of a developmentally disabled son and nobles intent on shedding each other's blood for power, and while he would not see the disastrous consequences himself, the consequences would soon come.
