Wang Jun (Pengzu)

In 299, during Empress Jia's rule behind the curtains, she had the Crown Prince, Sima Yu, under house arrest in Xuchang. The following year, Wang Jun and the eunuch Sun Lü (孫慮) assisted her in poisoning Sima Yu.[4] Wang Jun received the title General Who Pacifies The North and Imperial Inspector of Qingzhou. After a while, the court moved him to General Who Calms The Northern Frontiers and Chief Controller of Youzhou. While in Youzhou, Wang Jun sensed that civil war would soon ensue in northern China. Thus, he began initiating alliances with the neighbouring barbarian tribes to secure his position. He married his two daughters; one to the chieftain of the Xianbei Duan tribe, Duan Wuwuchen and another to a general of the Xianbei Yuwen tribe, Sunuyan (素怒延).[5]

In 301, Emperor Hui of Jin's regent, Sima Lun, deposed Hui and declared himself emperor. The three princes, Sima Ying, Sima Yong and Sima Jiong, promptly began an alliance to restore Emperor Hui. Wang Jun remained neutral throughout the war and refused the send out his troops. He even confiscated letters from the coalition calling to arms in Youzhou to prevent anyone from joining them. Sima Ying was particularly frustrated at Wang Jun's actions and considered attacking him but decided not to due to more pressing issues.[6] After overthrowing Sima Lun, Wang Jun received the office of General Who Secures the North.

In 304, Sima Ying and Sima Yong became Jin's paramount leaders after killing the Prince of Changsha, Sima Ai. While in power, Sima Ying sought to eliminate Wang Jun, still begrudging him for his conduct in 301. Wang Jun himself was also not pleased with the outcome of Sima Ying and Sima Ai's war. Sima Ying appointed his trusted subordinate, He Yan (和演), as Inspector of Youzhou with orders to assassinate Wang Jun. He Yan colluded with the Wuhuan Chanyu, Shen Deng (審登), and when the two travelled with Wang Jun to Qingquan (清泉; south of present-day Beijing), they agreed to have him killed there. However, a heavy storm drenched their troops' equipment and foiled their plans on the day of their attempt.[7]

Shen Deng perceived the storm as a sign that the Heavens favoured Wang Jun, so he defected to Wang Jun and revealed the plot. In response, Wang Jun and Shen Deng besieged He Yan and forced him to surrender. After executing He Yan, Wang Jun assumed total control over Youzhou. Sima Ying tried summoning Wang Jun to court, but Wang Jun camped at Jizhou instead. Wang Jun brought along Duan Wuwuchen and a Wuhuan chieftain, Jiezhu (羯朱), and allied with the Inspector of Bingzhou, Sima Teng. They defeated Sima Ying's general, Wang Bin (王斌), and as they approached Sima Ying's base in Yecheng, Wang Jun's vanguard general, Qi Hong, also defeated Shi Chao. Sima Ying panicked and fled to Luoyang, allowing Wang Jun to occupy his city. The Xianbei had Yecheng sacked and abducted many women from the city. After Wang Jun returned to Jicheng, he executed many of the Xianbei soldiers who partook in the abductions, and around 8,000 bodies reportedly filled the Yi River (易水; in present-day Yi County, Hebei).[8]

In 305, Wang Jun was one of the many governors east of Luoyang to acclaim the Prince of Donghai, Sima Yue, as coalition leader to overthrow Sima Yong and bring Emperor Hui back to Luoyang from Chang'an. Wang Jun lent his Xianbei troops to the Prince of Fanyang, Sima Xiao (司馬虓), which proved vital to defeating Sima Yong's powerful ally, Liu Qiao. Wang Jun later had Qi Hong lead his elite Xianbei and Wuhuan charging cavalry to serve in Sima Yue's vanguard. In June 306, Qi Hong and others entered Chang'an, and Wang Jun's Xianbei troops sacked the city, leaving 20,000 dead in their wake.[9]

After Emperor Hui returned to Luoyang, Wang Jun became Grand General of Agile Cavalry, Commander over the eastern tribes and the military affairs of Hebei, and acting Inspector of Youzhou for his contributions. The court also merged the state of Yan into Wang Jun's fief. In 307, Emperor Huai of Jin ascended the throne. He appointed Wang Jun Minister of Works and Protector of the Wuhuan.

Previously in 304, the Xiongnu nobleman, Liu Yuan, established his state of Han-Zhao and began a conquest of northern China. In 308, the Han general, Shi Le, attacked Changshan (常山; around present-day Shijiazhuang, Hebei) but was defeated by Wang Jun. The following year, Shi Le invaded Changshan again, but Wang Jun routed him at Mount Feilong (飛龍山, in present-day Xinzhou, Shanxi). In 310, Shi Le tried taking Xiangcheng County, but Wang Jun sent Duan Wuwuchen's son, Duan Wenyang, and defeated him. At the end of that year, Shi Le attacked Xindu and killed the Inspector of Jizhou, Wang Bin, so Wang Jun assumed control over Jizhou as acting Inspector.

Despite serving the same state, Wang Jun soon entered a rivalry with the Inspector of Bingzhou, Liu Kun. Liu Kun had allied with the Tuoba-Xianbei chieftain, Tuoba Yilu, and in 310, petitioned to make Yilu the Duke of Dai Commandery. However, at the time, Dai Commandery was a part of Wang Jun's domain in Youzhou. When Yilu received Dai Commandery, Wang Jun refused to cede the territory, so he attacked Yilu but was routed. Because of this incident, Wang Jun bore a grudge against Liu Kun.[10]

In 311, Emperor Huai of Jin gave out numerous promotions to his officials, including Wang Jun, whom he promoted to Grand Marshal, Palace Attendant, Grand Commander, and Chief Controller of Youzhou and Jizhou. However, before his envoys could arrive, the emperor and Luoyang were captured by Liu Yao during the Disaster of Yongjia. After the emperor's capture, Wang Jun set up an altar and chose an unknown candidate as the new Crown Prince. He then claimed that he received an imperial edict to grant appointments.[11] Wang Jun appointed two men, Tian Hui (田徽) and Li Yun (李惲), as Inspector of Yanzhou and Inspector of Qingzhou, respectively. He made himself acting Prefect of the Masters of Writings and then appointed his subordinate, Pei Xian, and his son-in-law, Zao Song (棗嵩), Masters of Writing.

As Bingzhou's population declined, Liu Kun sent his clansman Liu Xi (劉希) to gather people from Wang Jun's territory in the commanderies of Dai, Shanggu and Guangning (廣寧郡, in present-day Hebei and Beijing). Wang Jun saw Liu Kun's action as an intrusion, so he sent his general Hu Ju (胡矩) and the new Duan chieftain, Duan Jilujuan, to attack Liu Xi. Wang Jun's forces killed Liu Xi and returned the people to their commanderies.

In 312, Han's city of Yuanxiang (苑鄕, in present-day Hebei and Beijing) surrendered to Wang Jun, prompting Shi Le to lay siege on it. In response, Wang Jun sent Wang Chang (王昌) and Duan Jilujuan to attack Shi Le's base at Xiangguo. However, Duan Jilujuan's cousin, Duan Mopei, was captured in battle. Shi Le used Mopei as a hostage to negotiate peace with Jilujuan. However, to win the support of the Duan tribe, Shi Le also treated Mopei with courtesy, sent gifts to the tribe and swore an alliance with Jilujuan. The Duan tribe were impressed with Shi Le's conduct, so they withdrew from Xiangguo and began distancing themselves from Wang Jun.[12] Without the Duan's support, Wang Chang had to retreat, and Yuanxiang returned to Han.

Shortly after his victory at Xiangguo, Shi Le attacked Xindu again and killed the Inspector of Jizhou, Wang Xiang (王象), so Wang Jun replaced him with Shao Ju (邵舉). Later, Shi Le invaded Shangbai (上白; in present-day Guangzong County, Hebei)and killed Li Yun, so Wang Jun appointed Bao Sheng (薄盛) as the new Inspector of Qingzhou. Wang Jun planned to launch an attack on Shi Le with Zao Song and Duan Jilujuan, but Jilujuan refused to meet with Wang Jun. Realizing that the Duan tribe no longer supported him, Wang Jun allied with the Duan's rival Xianbei tribes, the Tuoba and Murong, to attack them. However, Duan Jilujuan defeated the Tuoba forces, while the Murong forces retreated upon hearing about their ally's defeat.

Shi Le later attacked Dingling (定陵; in present-day Xiangcheng County, Henan) and killed Tian Hui. Bao Sheng also surrendered to Shi Le, and Shi Le continued to capture more counties and commanderies in the east. As Wang Jun's influence continued to diminish, the Wuhuan leaders, Shen Guang (審廣), Jian Shang (漸裳) and Hao Xi (郝襲), all secretly defected to Shi Le's side.[13]

Despite his decline in power, Wang Jun still had ambitions to declare himself emperor, even more so after Emperor Huai was executed in 313 by Han. He subscribed to a prophecy stating that the one to replace Han bears the name 'High Road'.[lower-alpha 1][14] His officials criticized him for his imperial ambitions, but Wang Jun had them executed. The gentry was disturbed by Wang Jun's violent impulses and distanced themselves from him. Wang Jun also began to neglect political affairs, leaving them in the hands of his corrupted officials such as Zao Song, Zhu Shuo (朱碩) and Tan Heng (貪橫). The three men's policies were so troublesome that many of Wang Jun's people fled to Murong Hui in Liaodong.

Hearing Wang Jun's situation, Shi Le contemplated attacking him. At the advice of Zhang Bin, Shi Le pretended to appear weak, sending gifts and offering his surrender to Wang Jun through a letter in 313. As Wang Jun needed a talented figure after losing most of his subordinates at the time, he was delighted by his surrender and accepted it doubtlessly. To show his loyalty, Shi Le openly declined an offer from Wang Jun's general, You Tong (游統), to rebel against Wang. The following year, when Wang Jun's envoy went to Shi Le's headquarters in Xiangguo, Shi Le hid his strongest troops to give the illusion that he was weaker than Wang Jun. When presented with an elk tail by Wang Jun, Shi Le pretended to be afraid to grasp it and instead hung it on a wall to show his respect for him.[15] Finally, Shi Le sent a petition to visit Wang Jun, intending to submit and hail him as emperor later that year.

With the petition, Wang Jun was ready to accept Shi Le into his ranks. Before arriving at Jicheng, Shi Le killed You Tong's brother You Lun (游綸) when passing at Bairen (柏人; in present-day Xingtai, Hebei) to prevent the plan from leaking. Shi Le also sent a letter to Liu Kun, asking permission to attack Wang Jun, which Liu Kun allowed. As Shi Le drew closer, Wang Jun's generals and advisers insisted he immediately attack Shi Le, but Wang Jun scolded them and threatened to execute anyone who disobeyed him. Once he arrived, Wang Jun ordered the gatekeepers to let him in. Shi Le flooded the city with cattle and sheep seemingly as offerings to Wang Jun, but his true intention was to block the exits so that Wang Jun could not escape.[16] Wang Jun began to panic when he realized this, but it was too late. Shi Le entered the city, where he let loose his soldiers and sacked the place.

Wang Jun retreated to his chambers but was eventually arrested along with his wife by Shi Le's men. When brought face to face with Shi Le, Wang Jun scolded him and accused him of being treacherous. Shi Le responded by chastising Wang Jun for his disloyalty to the Jin imperial family and ignoring the plea of his subjects. Shi Le even stated that Wang Jun had abundant food in his granary but refused to distribute it to those affected by natural disasters.[17]

Shi Le sent Wang Jun to Xiangguo to be executed. On the way, Wang Jun attempted suicide by drowning in a river, but the guards managed to restrain him. Once at Xiangguo, Shi Le ordered Wang Jun beheaded in the marketplace, and Wang Jun reportedly continued to curse Shi Le up to his death.[18] Shi Le gifted Wang Jun's head to the Han emperor, Liu Cong, and also had many of Wang Jun's soldiers and aides killed.
