Emperor Hui of Jin, sim. ch. 晋惠帝, trad. ch. 晉惠帝, py. jìn huì dì, wg. Chin Hui-ti (259-poisoned January 8, 307), personal name Sima Zhong (司馬衷), courtesy name Zhengdu (正度), was the second emperor of the Jin Dynasty (265-420). Emperor Hui was a developmentally disabled ruler, and throughout his reign, there was constant internecine fighting between regents, imperial princes (his uncles and cousins), and his wife Empress Jia Nanfeng for the right to control him (and therefore the imperial administration), causing great suffering for the people and greatly undermining the stability of the Jin regime, eventually leading to Wu Hu rebellions that led to Jin's loss of northern and central China and the establishment of the competing Sixteen Kingdoms. He was briefly deposed by his granduncle Sima Lun, who usurped the throne himself, in 301, but later that year was restored to the throne and continued to be the emperor until 307, when he was poisoned, likely by the regent Sima Yue.
As Crown Prince Zhong grew in age, his developmental disability became clear to his parents and the imperial officials alike. He learned how to write and to speak, but appeared to be unable to make logical decisions on his own at all. Once, when he heard frogs croaking, he asked, in all seriousness, "Do they croak because they want to, or because the government ordered them to?" In a more famous pronouncement, when he once was taught about the victims of a famine not having rice to eat, he became puzzled and asked, "If they do not have rice, why not have meat stew?" Several times, officials reminded Emperor Wu of this, and Emperor Wu, not realizing the extent of Crown Prince Zhong's disability, resisted the implicit calls for him to be replaced. Indeed, because Emperor Wu was concerned that many officials were impressed with his talented younger brother, Sima You the Prince of Qi and might want Prince You to replace him instead, he eventually had Prince You sent to his principality, and Prince You died in anger in 283.
In 272, at age 12, Crown Prince Zhong married Jia Chong's daughter Jia Nanfeng, who at 14 was two years older. Crown Princess Jia was violent and jealous, but had her methods of controlling Crown Prince Zhong so that he both loved and feared her. She bore him four daughters during their marriage, but she would not bear his only son Sima Yu -- whose mother Consort Xie Jiu was originally a concubine of Emperor Wu, but had been given to Crown Prince Zhong prior to his marriage to Crown Princess Jia, so that Consort Xie could teach him how to have sexual relations. Consort Xie became pregnant and bore Sima Yu, who was much favored by his grandfather Emperor Wu. Emperor Wu considered Prince Yu intelligent and very much like his own grandfather Sima Yi, and this played into his decision not to replace Crown Prince Zhong. However, other than Consort Xie, no other concubine would bear Crown Prince Zhong a child -- as several had been pregnant but each was murdered by Crown Princess Jia, in fits of jealousy. (Emperor Wu, in anger, considered deposing Crown Princess Jia, but with the intercession of his second wife Empress Yang Zhi, he recalled Jia Chong's contributions to the establishment of Jin Dynasty, and decided to leave her in place.)
In 289, as Emperor Wu neared death, he considered whom to make the regent for Crown Prince Zhong. He considered both Empress Yang's father 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 (許昌, in modern Xuchang, Henan). 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, and Crown Prince Zhong ascended the throne as Emperor Hui. Crown Princess Jia became empress, and Prince Yu became crown prince.
Empress Jia, however, wanted to be involved in the government, and was angry that she was constantly rebuffed by Empress Dowager Yang and Yang Jun. She therefore conspired with the eunuch Dong Meng (董猛) and the generals Meng Guan (孟觀) and Li Zhao (李肇) against the Yangs. She tried to include Sima Liang into the conspiracy, but Sima Liang declined; instead, she persuaded Emperor Hui's brother, Sima Wei the Prince of Chu, to join her plan. In 291, after Sima Wei returned to Luoyang from his defense post (Jing Province (荊州, modern Hubei and Hunan)) with his troops, a coup went into progress.
Empress Jia, who had her husband easily under her control, had him issue an edict declaring that Yang Jun had committed crimes and should be removed from his posts. It also ordered Sima Wei and Sima Yao (司馬繇) the Duke of Dong'an to attack Yang's forces and defend against counterattacks. Quickly, it became clear that Yang was in trouble. Empress Dowager Yang, trapped in the palace herself, wrote an edict ordering assistance for Yang Jun and put it on arrows, shooting it out of the palace. Empress Jia then made the bold declaration that Empress Dowager Yang was committing treason. Yang Jun was quickly defeated, and his clan was massacred. Empress Dowager Yang was deposed and imprisoned (and would die in 292 in imprisonment). Sima Liang was recalled to serve as regent, along with the senior official Wei Guan.
In summer 291, Empress Jia had Emperor Hui personally write an edict to Sima Wei, ordering him to have Sima Liang and Wei removed from their offices. His forces thereby surrounded Sima Liang and Wei's mansions, and while both men's subordinates recommended resistance, each declined and was captured. Against what the edict said, both were killed -- Sima Liang with his heir Sima Ju (司馬矩) and Wei with nine of his sons and grandsons. Qi then suggested to Sima Wei to take the chance to kill Empress Jia's relatives and take over the government, but Sima Wei hesitated -- and at the same time, Empress Jia came to the realization that killing Sima Liang and Wei, if it had been realized that she intended it, could bring a political firestorm and that also Sima Wei would not be easily controlled. She therefore publicly declared that Sima Wei had falsely issued the edict. Sima Wei's troops abandoned him, and he was captured and executed. Sima Liang and Wei were posthumously honored. However, after this point on, Empress Jia became the undisputed power behind the throne for several years.
In 296, the Di and Qiang of Qin (秦州, modern eastern Gansu) and Yong (雍州, modern central and northern Shaanxi) started a major rebellion against Jin Dynasty, and they supported the Di chieftain Qi Wannian (齊萬年) to be emperor. In 297, the Jin general Zhou Chu (周處), without support from the central government, was easily defeated by Qi. A large group of refugees, most of Di ancestry, stricken by the famine that resulted from the warfare, fled south into Yi Province (益州, modern Sichuan and Chongqing), led by Li Te (李特). (Several years later, they would eventually be forced into rebellion and peel away from Jin rule.) In 299, Meng Guan was able to defeat Qi, but Qi would foreshadowed much more serious non-Han rebellions of the future. Later in 299, the mid-level official Jiang Tong (江統) would petition Empress Jia to have the five non-Han ethnicities (the Wu Hu) removed from the empire proper and relocated to regions outside the empire, but Empress Jia did not accept his suggestions.
The relationship between Empress Jia and Crown Prince Yu had always been an uneasy one. Empress Jia's mother Guo Huai (郭槐) had constantly advised Empress Jia to treat Crown Prince Yu well, as her own son, and she advocated marrying Jia Mi's sister to Crown Prince Yu. However, Empress Jia and Jia Wu opposed this, and instead married a daughter of the official Wang Yan (王衍) to Crown Prince Yu. (Wang had two daughters, but Empress Jia had Crown Prince Yu marry the less beautiful one and had Jia Mi marry the more beautiful one.) After Lady Guo's death, the relationship between Empress Jia and Crown Prince Yu quickly deteriorated, as Jia Wu and Consort Zhao provoked difficulties between them. Further, Crown Prince Yu and Jia Mi never liked each other, and Jia Mi, as a result, also advised Empress Jia to depose Crown Prince Yu. In 299, Empress Jia agreed and took action. When Crown Prince Yu was in the palace to make an official petition to have his ill son Sima Bin (司馬彬) created a prince, Empress Jia forced him to drink a large amount of wine and, once he was drunk, had him write out a statement in which he declared intention to murder the emperor and the empress and to take over as emperor. Empress Jia presented the writing to the officials and initially wanted Crown Prince Yu executed -- but after some resistance, she only had him deposed and reduced to status of a commoner. Crown Prince Yu's mother Consort Xie was executed, as was his favorite concubine Consort Jiang Jun (蔣俊).
In 300, under the advice of a prince she favored -- Sima Lun the Prince of Zhao, Emperor Wu's granduncle -- Empress Jia decided to eliminate Crown Prince Yu as a threat. She sent assassins and had Crown Prince Yu assassinated. Sima Lun, however, had other plans -- he wanted to have Empress Jia murder the crown prince so that he could use the murder as an excuse to overthrow her, and he started a coup later that year, killing Jia Mi, Zhang, Pei, and other associates of Empress Jia. Empress Jia was deposed and later forced to commit suicide. Sima Lun and his strategist Sun Xiu (孫秀) became the paramount authority.
After defeating Sima Yun, Sima Lun became ever more intent on usurping the throne. Late in 300, after Sun Xiu's suggestion, Sima Lun was granted the nine bestowments. However, Sima Lun and his sons were themselves foolish and unintelligent, and Sun was the actual person in charge of the government. In the winter, Sun had the granddaughter of his distant relative and friend Sun Qi (孫旂), Yang Xianrong, married to Emperor Hui to be his empress.
Also in winter 300, the governor of Yi Province, Zhao Xin (趙廞), a relative of Empress Jia, rebelled and tried to occupy Yi Province to be his own domain. He associated with Li Te and his brother Li Xiang (李庠), and they soon were able to take over Yi Province. However, he then became suspicious of the Li brothers' abilities, and he killed Li Xiang after Li Xiang suggested that he declare himself emperor. Li Te, in anger, took his troops and killed Zhao. Li then welcomed the new Jin governor Luo Shang (羅尚) to the provincial capital Chengdu (成都, in modern Chengdu, Sichuan), but maintained an uneasy relationship with Luo and Luo's main strategist, Xin Ran (辛冉), a former friend of his who deeply suspected his intentions.
In spring 301, Sima Lun had Emperor Hui yield the throne to him, and gave Emperor Hui the honorific title of retired emperor (太上皇). In order to appease those who might be angry at his usurpation, he rewarded many people with honors. Sun, in particular, was issuing edicts based on his own whims. Suspecting three key princes -- Sima Jiong the Prince of Qi (Emperor Hui's cousin and the son of Emperor Hui's uncle, Prince You of Qi), Sima Ying the Prince of Chengdu (Emperor Hui's brother), and Sima Yong the Prince of Hejian (the grandson of Emperor Hui's great-granduncle Sima Fu the Prince 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 brother), and Sima Xin (司馬歆) the Duke of Xinye (the son of a granduncle of Emperor Hui) 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 and Ying's forces, and after just declaring himself emperor for three months, Sima Lun was captured by officials in Luoyang who declared for the rebellion as well, and forced to issue an edict returning the throne to Emperor Hui. He was then forced to commit suicide. Sun and other associates of Sima Lun were executed.
Some thought that a power balance that Emperor Wu had hoped for at his death might be restored, as Princes Jiong and Ying were each given regent titles (and awarded the nine bestowments, in one rare case where the nine bestowments were not signs of an impending usurpation, although Prince Ying declined the bestowments), and many talented officials were promoted into important positions. However, the Princes Jiong and Ying were actually apprehensive of each other's power, and Prince Ying decided to yield the central government regency to Prince Jiong at the time and return to his defense post at Yecheng.
In the capital, Sima Jiong became arrogant based on his accomplishments. He had his sons created princes, and ran the matters of the central government from his mansion, rarely visiting the emperor or attending the imperial meetings. He enlarged his mansion to be as large as the palace, and he entrusted matters to people who were close to him, and would not change his ways even when some of his more honest associates tried to change his behavior. When Emperor Hui's grandsons Sima Zang and Sima Shang (司馬尚), successive crown princes, died in childhood, leaving Emperor Hui without male descendants by 302, Sima Ying was considered the appropriate successor, but Sima Jiong chose to bypass him by recommending the seven-year-old Sima Qin (司馬覃) the Prince of Qinghe (Emperor Hui's nephew and the son of his brother Sima Xia (司馬遐)) as the crown prince, with intent to easily control the young Crown Prince Qin.
Sima Jiong became suspicious of Sima Yong the Prince of Hejian -- because Sima Yong had initially wanted to support Sima Lun, until he saw that Sima Lun's cause was hopeless. Sima Yong knew of Sima Jiong's suspicion, and started a conspiracy; he invited Sima Ai the Prince of Changsha to overthrow Sima Jiong, believing that Sima Ai would fail; his plan was then to, in conjunction with Sima Ying, start a war against Sima Jiong. Once they were victorious, he would depose Emperor Hui and make Sima Ying the emperor, and then serve as Sima Ying's prime minister. In winter 302, Sima Yong declared his rebellion, and Sima Ying soon joined, despite opposition from his strategist Lu Zhi (盧志). Hearing that Sima Ai was part of the conspiracy as well, Sima Jiong made a preemptive strike against Sima Ai, but Sima Ai was prepared and entered the palace to control Empeorr Hui. After a street battle, Sima Jiong's forces collapsed, and he was executed. Sima Ai became the effective regent, but in order to reduce opposition, he submitted all important matters to Sima Ying, still stationed at Yecheng.
Meanwhile, in Yi Province, in 303, Luo Shang, after causing Li Te to be ready by offering a truce, made a surprise attack against Li's forces and killed him. Li's forces fell under the command of his brother Li Liu (李流), who died later that year as well and was succeeded by his nephew Li Xiong. Under Li Xiong's command, the refugee forces were able to defeat not only Luo's forces but also reinforcements sent by Jing Province (荊州, modern Hubei and Hunan). At the same time of Li's successes, many agrarian rebellions also started throughout the empire, including one that defeated the forces of the powerful Sima Xin the Prince of Xinye and killed him.
In fall 303, Sima Yong, dissatisfied that his plan did not come to fruition, persuaded Sima Ying to again join him against Sima Ai. While Sima Yong and Sima Ying had overwhelming force, their forces could not score a conclusive victory against Sima Ai. Sima Yong's forces were about to withdraw in spring 304 when Sima Yue the Prince of Donghai, the grandson of a great-granduncle of Emperor Hui, believing that Sima Ai could not win this war, arrested him and delivered him to Sima Yong's general Zhang Fang, who executed Sima Ai cruelly by burning him to death. Sima Ying became in effective control of the government, but continued to control it remotely from Yecheng.
Wang Jun (王浚), the military commander of You Province (幽州, modern Beijing, Tianjin, and northern Hebei), who had an uneasy relationship with Sima Ying up to this point, then declared against Sima Ying and headed south with his troops, allied with various Xianbei and Wuhuan tribes. Sima Ying found it difficult to resist them, and he sent one of his subordinates, the Xiongnu noble Liu Yuan, to his own tribesmen to ask them to join him. Once Liu left, however, Sima Ying's forces collapsed. When Liu heard this, instead of bringing his forces to Sima Ying's aid, he declared independence and entitled himself the Prince of Han -- claiming rightful inheritance of Han Dynasty, as he claimed to be descended from a Han princess who had married a Xiongnu chanyu -- and thus establishing Han Zhao. (A month earlier, Li Xiong had declared himself independent of Jin as well, as the Prince of Chengdu, establishing Cheng Han; these two states would be the first two of the Sixteen Kingdoms.)
Sima Ying fled back to Luoyang with Emperor Hui, but now with no forces backing him. Sima Yong, in control of the situation, decided to directly take control without using Sima Ying any longer, and Sima Ying was removed from the crown prince position and replaced with another brother of Emperor Hui's -- Sima Chi the Prince of Yuzhang, who was considered studious and humble. Sima Yong also had Zhang Fang forcibly move Emperor Hui to Chang'an (in modern Xi'an, Shaanxi), directly under his own grasp. However, a number of high-level officials remained in Luoyang and formed a separate government that was partially allied with and partially rivalling Sima Yong's.
At the same time, however, the Jin infighting continued. In the fall of 305, Sima Yue declared yet another rebellion, this time against Sima Yong, claiming that Sima Yong had improperly forced Emperor Hui to move the capital. Various provincial governnors and military commanders were forced to be on one side or the other. The war was initially inconclusive. In early 306, after a few victories by Sima Yue, Sima Yong became fearful, and he executed Zhang to seek peace; Sima Yue refused. By summer 306, Sima Yong was forced to abandon both Chang'an and Emperor Hui, and Sima Yue's forces welcomed Emperor Hui back to Luoyang and restored Empress Yang.
Also in 306, both Li Xiong and Liu Yuan declared themselves emperors, even more clearly breaking from Jin.
