Jiang Chong

Biography

Family Background and Early Years

Jiang Chong's original name was Jiang Qi. He came from Handan in Zhao Kingdom. His younger sister was skilled in music and dance and married the Zhao crown prince Liu Dan, allowing Jiang Qi to become an honored guest of King Jingxu of Zhao, Liu Pengzu. Jiang Qi was treated well at the Zhao court, but because he knew many of Crown Prince Liu Dan's private affairs, relations between the two deteriorated. Liu Dan suspected Jiang Qi of revealing his secrets to the king and sent officials to arrest him. Jiang Qi escaped, but Liu Dan seized and killed his father and elder brother. To evade further danger Jiang Qi hid, fled west through Hangu Pass, changed his name to Jiang Chong, and permanently broke with Zhao.

Accusing the Crown Prince of Zhao

After entering the passes, Jiang Chong submitted a memorial at the imperial palace accusing Liu Dan of sexual misconduct with his full sister and women of the king's harem and of colluding with powerful and lawless men in the commanderies and kingdoms to engage in violent crime beyond the control of local officials. Emperor Wu was enraged by the memorial and sent envoys to mobilize commandery officials and troops to surround the Zhao palace, arrest Liu Dan, and transfer him to the imperial prison of Wei Commandery for trial by the Commandant of Justice. He was sentenced to death. King Liu Pengzu of Zhao, Emperor Wu's half-brother, memorialized in defense of his son, arguing that Jiang Chong was only a fugitive petty official using imperial authority to avenge a private grievance. He offered Zhao warriors for service against the Xiongnu in exchange for Liu Dan's life. Emperor Wu refused. Liu Dan escaped execution but lost his position as crown prince. The episode brought Jiang Chong to Emperor Wu's attention.

Emperor Wu's Favor

Emperor Wu first summoned Jiang Chong at Quantai Palace in Shanglin Park. Jiang Chong requested permission to appear in his ordinary clothing, which the emperor allowed. He entered wearing a light gauze robe, a buyao cap decorated with feathered tassels, and presented an imposing physical appearance. Emperor Wu immediately found him remarkable and said to those nearby, “燕、赵固多奇士.” Asked about current affairs, Jiang Chong answered effectively and pleased the emperor. He then volunteered to serve as envoy to the Xiongnu. When the emperor asked his plan, Jiang Chong replied: “因变制宜，以敌为师，事不可豫图.” Emperor Wu appointed him an imperial envoy. After returning, he became an embroidered-clothing direct envoy, charged with suppressing banditry in the Three Capital Commanderies and inspecting excessive luxury and violations of status regulations.

Jiang Chong enforced the law without avoiding the powerful. Imperial relatives and favored courtiers often exceeded sumptuary limits; Jiang Chong impeached them one by one and asked that their carriages and horses be confiscated and that they report to the Northern Army for possible service against the Xiongnu. After Emperor Wu approved, Jiang Chong sent notices to the Chamberlain for Attendants and the Yellow Gates forbidding those impeached from entering palace precincts. The relatives and aristocratic youths panicked, kowtowed for mercy, and paid tens of millions of cash to redeem themselves. Emperor Wu regarded Jiang Chong as loyal, upright, and obedient to the law and placed great trust in him.

Feared in the Capital

While inspecting outside the palace, Jiang Chong encountered the carriage procession of Grand Princess Guantao traveling on the imperial road. He stopped the party. The princess claimed an order from the Empress Dowager; Jiang Chong replied that the princess alone might use the road, not her attendants, and confiscated their vehicles and horses. Later, while accompanying Emperor Wu to Ganquan Palace, he encountered a messenger from the crown prince's household using the imperial road and sent him for punishment. Crown Prince Liu Ju asked that the matter be overlooked, but Jiang Chong refused and reported it directly to the emperor. Emperor Wu praised him, saying, “人臣当如是矣.” Jiang Chong's authority and reputation for strictness grew, and he was promoted to Commandant of the Water Conservancy. His relatives and acquaintances benefited from his position. He was later dismissed after violating the law himself.

Framing the Crown Prince

During the Zhenghe era, Zhu Anshi of Yangling accused Chancellor Gongsun He's son, Grand Coachman Gongsun Jingsheng, of using witchcraft to curse the emperor. Gongsun He and his son were executed, and Princesses Yangshi and Zhuyi were also implicated. Emperor Wu later became ill while staying at Ganquan Palace. Seeing the emperor's old age and fearing that the crown prince would execute him after the emperor's death, Jiang Chong devised a plan and memorialized that the emperor's illness was caused by witchcraft. Emperor Wu appointed him to investigate.

Jiang Chong led Hu shamans in digging for effigies and arrested people who conducted night rituals or were accused of curses. Confessions were extracted by burning iron and other coercive methods. People began denouncing one another, and tens of thousands were reportedly executed. Reading Emperor Wu's suspicions, Jiang Chong ordered the Hu shaman Tan He to claim falsely that there was a witchcraft aura inside the palace and that the emperor would not recover unless it was removed. Emperor Wu believed the claim and ordered Jiang Chong to investigate the palace thoroughly. He first investigated lesser-favored consorts, then Empress Wei Zifu, and finally the crown prince's residence, where wooden effigies were dug up.

Crown Prince Liu Ju, unable to prove his innocence and terrified, accepted the advice of Junior Mentor Shi De, issued a forged edict, and arrested and killed Jiang Chong. Before killing him, the crown prince cursed him: “赵虏！乱乃国王父子不足邪！乃复乱吾父子也！” He then raised troops to defend himself. Emperor Wu ordered Chancellor Liu Qumao to suppress the uprising. Fighting in Chang'an lasted five days and killed tens of thousands. The crown prince fled and later hanged himself at Quanjiu Village in Hu County. Empress Wei Zifu also committed suicide.

Aftermath

After the Witchcraft Disaster, Emperor Wu gradually came to recognize that much of Jiang Chong's investigation had been fraudulent and ordered the extermination of Jiang Chong's three clans. He later built the Palace of Grieving for the Son and, at the place where the crown prince died, the Platform of Returning to Look and Grieve, to express sorrow.

Major Activities

Accusing the Zhao Crown Prince

Jiang Chong's career began with his accusation against Zhao crown prince Liu Dan. The charges involved sexual misconduct within the royal household and collusion with powerful lawless figures in the commanderies and kingdoms. Emperor Wu consequently deposed Liu Dan. The accusation both avenged the killing of Jiang Chong's father and brother and opened Jiang Chong's path into the central court.

Law Enforcement in the Three Capital Commanderies

As an embroidered-clothing direct envoy, Jiang Chong supervised bandit suppression around the capital and investigated violations by imperial relatives and favored courtiers. He impeached aristocrats, requested confiscation of vehicles and horses, confronted Grand Princess Guantao's entourage for using the imperial road, and arrested a messenger from the crown prince's household. His willingness to enforce regulations against the powerful won Emperor Wu's trust but also made enemies among the crown prince's circle and imperial relatives.

Mission to the Xiongnu

Jiang Chong once served as envoy to the Xiongnu. Emperor Wu appreciated his stated principle of adapting to changing circumstances and taking the enemy as a teacher, and the mission became an important step in his promotion.

Leading the Witchcraft Disaster

The central historical event of Jiang Chong's career was his role in the Witchcraft Disaster. Exploiting Emperor Wu's suspicions late in life, he ordered the Hu shaman Tan He to falsely claim witchcraft in the palace and used the investigation to create a large-scale judicial persecution. Tens of thousands were implicated, and Jiang Chong eventually directed the accusation toward Empress Wei and Crown Prince Liu Ju. After wooden effigies were dug up in the crown prince's residence, Liu Ju issued a forged edict and killed Jiang Chong, triggering armed fighting in Chang'an. The crown prince was defeated and died by suicide, the empress also died by suicide, and the political order of Western Han was severely shaken.

Relations with Contemporaries

Jiang Chong's relationship with Zhao crown prince Liu Dan changed from association to hostility, and he also became an enemy of Zhao king Liu Pengzu. At court, he became involved with cases implicating Chancellor Gongsun He and his son, Princess Yangshi, Princess Zhuyi, and others. He stood in direct opposition to Crown Prince Liu Ju and Empress Wei Zifu. He worked with Marquis Han Shuo, Censor Zhang Gan, eunuch Su Wen, and others in the witchcraft investigations.

Historical Assessment

Han / Contemporary

• Ban Gu placed Jiang Chong among the biographies of favored and treacherous figures in the Book of Han, writing that “江充造蛊，太子杀,” and compared him with notorious schemers from earlier history, warning that such men could use distant relationships to destroy intimate ones and small matters to overturn great affairs.
• Emperor Wu's extermination of Jiang Chong's three clans and construction of memorial buildings for the crown prince in his later years amounted to an official repudiation of Jiang Chong's conduct.
• Contemporary officials and aristocrats generally feared Jiang Chong, and no one dared openly defend him after the disaster.

Song and Yuan

• Southern Song scholar Qian Shi wrote in Liang Han Biji that petty men often advance by presenting themselves as loyal and upright, and that if rulers grant such men power without discernment they become great villains; he used Jiang Chong and Lu Qi as examples. He regarded Jiang Chong's fearless impeachment of the powerful not as genuine integrity but as a way to establish authority and win favor.
• Southern Song scholar Wang Yinglin, in Kunxue Jiwen, likewise treated Jiang Chong as one of the destructive ministers of Western Han.
• Yuan historian Hu Sanxing, in his annotations to the Comprehensive Mirror in Aid of Governance, explicitly condemned Jiang Chong's framing of the crown prince.

Ming and Qing

• Late-Ming and early-Qing scholar Ding Yaokang argued that Jiang Chong alone did not “kill the crown prince”; rather, Emperor Wu's own trust in a sinister petty man created the conditions for the catastrophe.
• Ming writer Zhong Xing, in Shihuai, analyzed Jiang Chong's psychology in detail, arguing that he began by escaping death and ended by pursuing advantage, and that once committed to the course of framing the crown prince he could not retreat.
• Qing scholar Wang Mingsheng, in Discussions of the Seventeen Histories, regarded Jiang Chong's use of Emperor Wu's suspicions for private revenge as an important factor in the deterioration of Western Han politics.
• Qing historian Zhao Yi, in Notes on the Twenty-Two Histories, likewise treated the Witchcraft Disaster as a product of Emperor Wu's harsh and suspicious late rule, which gave men such as Jiang Chong an opportunity.

Modern

• Lü Simian, in History of Qin and Han, regarded the Witchcraft Disaster as a major expression of Emperor Wu's late political crisis and argued that Jiang Chong's personal ambition combined with the emperor's suspicion to produce tragedy.
• Lin Jianming, in History of Qin and Han, argued that Jiang Chong dared offend the crown prince not from a genuine wish to uphold law but because he perceived the waning favor of Empress Wei Zifu.
• Frontier Perspectives on Qin-Han History and Culture, edited by Wang Jian, describes the Witchcraft Disaster led by Jiang Chong as a product of increasingly acute social contradictions that had major political, economic, military, and intellectual consequences.
• Tian Yuqing, in “On the Luntai Edict,” analyzes the relationship between the Witchcraft Disaster and Emperor Wu's late policy shift and treats Jiang Chong's framing of the crown prince as a symptom of imbalance in the late-Wudi political order.
