Zhang Dun

Biography

Family Background and Early Life

Zhang Dun was born into a prominent official family in Pucheng, Jian Prefecture, now Pucheng County, Nanping, Fujian. His father Zhang Yu rose to Grand Master of Imperial Accord with Silver Seal and Blue Ribbon. The Zhang clan was a leading family of Pucheng and produced many officials. When Zhang Dun was young, his older kinsman Zhang Dexiang was struck by his character and bearing and predicted that he would attain high rank. Du Dagui's Mingchen Beizhuan Wanyan Ji records this prediction.

Zhang Dun was described as forthright and uninhibited. Wei Tai's Dongxuan Bilu states that in youth he enjoyed practices of self-cultivation and was especially candid in temperament. Other sources portray him as handsome, elegant, and relaxed in manner. The History of Song calls him learned, skilled in writing, and exceptionally quick in judgment. When young he practiced breathing and fasting techniques associated with cultivation and was portrayed as having an almost Daoist air.

Zhang Dun and his clansman Zhang Jie were both prominent and sometimes referred to together as the "two Zhangs." Wang Mingqing's Huizhu Lu places them alongside famous literary groupings such as the "two Sus" and "three Sus," reflecting the standing of the clan. Zhang Dun was also a friend of Wang Guan. Because both men were known for a loose and unconventional manner, contemporaries nicknamed them "Guan Three and Dun Seven."

Examinations and Early Official Career

In 1057, the second year of Jiayou, Zhang Dun went to the capital and passed the jinshi examination. His younger kinsman Zhang Heng, however, placed first. Ashamed to rank below his junior relative, Zhang Dun refused to accept the appointment document, threw it aside, and returned home. The History of Song records the incident as a sign of his proud temperament.

In 1059 he sat the examination again, passed in the first class, and was appointed magistrate of Shangluo, in present-day Shangluo, Shaanxi. He later served as Jiedu Tuiguan of Xiongwu Command, in present-day Tianshui, Gansu.

In 1066 Zhang Dun won the appreciation and recommendation of Ouyang Xiu, then Assistant Grand Councilor, and was summoned for an examination for a scholarly post. Although he passed, Wang Tao attacked him and he did not receive the appointment; instead he became magistrate of Wujin. In 1067 he served as Zhuzuo Zuolang. Censors Lü Jing and Jiang Zhiqi again attacked his character and cited his earlier rejection of the appointment edict, preventing another appointment to a scholarly post.

Joining the Reforms and Expanding the Frontier

In 1069 Li Chengzhi recommended Zhang Dun to Wang Anshi. Wang initially expressed doubts about Zhang's conduct, but Li answered that his talent was useful and urged Wang to speak with him directly. Zhang Dun was eloquent and adept at responding to Wang's concerns, and Wang reportedly regretted not having met him earlier. From then on Zhang Dun became a core participant in Wang Anshi's reform program.

Wang Anshi established the Three Fiscal Agencies Regulations Office and appointed Zhang Dun as an editor there, adding posts connected with Jixian Hall and the Secretariat. Zhang participated in drafting the New Policies, supervised the compilation of official history, and worked on veritable records. In 1071 he was sent to analyze non-Han affairs in Yu Prefecture and labor-service matters in Kuizhou Circuit. After the Regulations Office was dissolved, he became a reviewing official in the Secretariat's revenue section and also worked on regulations governing fiscal agencies, offices, and annual accounts. He was sent to Bin Prefecture to investigate a case and used the journey to examine implementation of the new hired-service system in Shaanxi. He proposed that the government purchase grain in large quantities when prices were low and move troops toward harvest-rich areas in peacetime so they could draw local provisions. Emperor Shenzong accepted these proposals.

In 1072 Zhang Dun became inspection commissioner for northern and southern Jinghu, directing policy toward non-Han communities in the Nanjiang and Beijiang regions. He used forceful measures to expand Song administration. The source credits the campaign with bringing 4,809 households and 260,000 mu of land under control, changing Xia Prefecture to Anjiang Stockade and Fu Prefecture to Zhenjiang Stockade. He subsequently rose through posts including Rujing Fushi, diarist, drafting official, and supervisor of the Directorate for Armaments. In 1073 the court established agricultural colonies in northern Jinghu, and Zhang Dun was appointed pacification commissioner of Jingyuan Circuit and then of Gaoyangguan Circuit.

In 1074 Emperor Shenzong ordered Zhang Dun to establish a special office at the Directorate for Armaments to review Zeng Bu's investigation of the market-exchange program. In the ninth month, Shenzong, who valued Zhang highly, made him State Finance Commissioner, placing him in charge of national finances.

Reverses and Return to Power

In 1075 Wang Anshi returned to the chancellorship while Lü Huiqing was sent out as prefect of Chen Prefecture. Censor-in-chief Deng Wan accused Zhang Dun of belonging to Lü's faction and helping him in wrongdoing. Zhang was therefore sent out as prefect of Huzhou.

In the tenth month of 1076, unrest broke out in Xia, Chen, and Yuan prefectures. The court appointed Zhang prefect of Jingnan, the principal city of northern Jinghu, and gave him additional military responsibilities. He was ordered to travel personally to Chen and Yuan to pacify the rebels. Zhang hurried there at double speed and continued even after falling from his horse and injuring his foot. He established Cheng Prefecture. In the fifth month he was transferred to Hangzhou, but before taking up the post he was recalled as a Hanlin academician. He then left office to mourn his mother's death. After mourning, he served in posts including director of the Three Institutes and Palace Library, head of the Bureau of Personnel Evaluation, and Hanlin academician.

In 1080 Zhang Dun became Assistant Grand Councilor. In 1081 his father Zhang Yu occupied land belonging to a commoner named Shen Li. When Shen stopped Zhang Dun's carriage to complain, Zhang had him seized and sent to Kaifeng. The Court of Judicial Review impeached Zhang Yu and Zhang Dun's younger brother Zhang Kai for occupying commoners' land. Zhang Dun was therefore dismissed as Assistant Grand Councilor and sent to govern Cai Prefecture, later serving in Chen and Ding prefectures. In 1082 he was recalled as Vice Director of the Chancellery and became the senior vice-chancellor.

Succession Settlement and Yuanyou Demotion

In 1085 Emperor Shenzong became critically ill. Some officials considered installing either Zhao Hao, Prince of Yong, or Zhao Jun, Prince of Cao, younger brothers of Shenzong. Zhang Dun joined Chancellor Wang Gui and other senior ministers in deciding to establish Shenzong's eldest son Zhao Yong as crown prince. Zhang Dun wrote the proposal on paper, and Wang Gui showed it to the emperor, who could no longer speak and indicated assent by nodding. They also requested that Empress Dowager Gao govern from behind the curtain; Shenzong agreed. The crown prince, later renamed Zhao Xu, ascended the throne as Emperor Zhezong. In the fifth month Zhang Dun became Zhi Shumiyuan Shi.

Because Zhezong was young, Empress Dowager Gao governed as regent and Sima Guang became a leading chancellor. Sima sought to abolish the New Policies almost in their entirety. Zhang Dun, as the official in charge of the Bureau of Military Affairs, repeatedly debated him over the Service Exemption Law. Zhang argued before the regent that the original switch from compulsory service to hired substitutes had been carried out too rapidly and had produced harm, but that reversing the system within only five days would cause still greater damage. He submitted a memorial of several thousand characters analyzing the strengths and weaknesses of the exemption and corvée systems and rebutting Sima Guang's criticism.

Sima Guang also supported ceding territory to Western Xia. Zhang Dun reacted angrily, saying those who proposed the policy deserved execution and insulting Sima as a useless village teacher. Empress Dowager Xuanren was furious. Liu Zhi and other censors attacked Zhang in succession, and he was sent out as prefect of Ru Prefecture. Lü Gongzhu said that some of Zhang's arguments were worth considering but criticized him for being intent on winning disputes without regard for the larger dignity of the court. Zhang later served as prefect of Hangzhou and again of Ru Prefecture. In the eleventh month of 1086 he asked to leave office and was made administrator of Dongxiao Palace, but conservative attacks continued. Even while mourning his father's death, he remained a target of criticism.

The Shaosheng Restoration and the Chancellorship

In 1093 Emperor Zhezong assumed personal rule and recalled Zhang Dun as chancellor with the explicit goal of continuing Emperor Shenzong's policies. The source summarizes the program as restoring everything changed during the Yuanyou era. Zhang brought Cai Bian and other allies into important positions. He requested that memorials submitted by Yuanyou officials be collected and classified and moved against Liu Anshi, Fan Zuyu, and others. He also used writings from Wen Jifu to encourage Cai Wei to accuse Liu Zhi and Liang Tao of plotting rebellion, producing the Tongwenguan prison case and ordering Cai Jing, An Dun, and Jian Xuchen to investigate it to the end.

In 1094, the first year of Shaosheng, Zhang Dun gradually restored the Service Exemption Law, Mutual Security (baojia) Policy, Green Shoots Policy, and other Xining measures. Under his direction, edicts concerning the ever-normal granaries, service exemption, agricultural waterworks, and baojia were compiled and promulgated across the empire, largely restoring the Xining reforms. Zhang also insisted on destroying the tomb structures of Sima Guang and Lü Gongzhu. Zhezong regarded the act as useless, but Zhang persisted; the memorial arches and inscriptions were destroyed or erased, and the two men were posthumously stripped of honors. Living political enemies including Wang Yansou, Lü Dafang, Liu Zhi, Su Zhe, Liang Tao, Fan Chunren, Liu Fengshi, and Han Wei were demoted on the same day and sent to remote prefectures.

In 1096 Zhang Dun used allegations of sorcery and cursing to urge Emperor Zhezong to depose Empress Meng, who had been chosen under Empress Dowager Xuanren, and replace her with Empress Liu. The source records Zhezong lamenting that Zhang Dun had damaged his moral reputation through the affair.

Later Years and Posthumous Treatment

Emperor Zhezong died childless in 1100. Zhang Dun opposed the succession of Zhao Ji, Prince Duan, and supported Zhao Si, Prince Jian. Empress Dowager Xiang rejected the proposal. Zhang then said that even Zhao Bi, Prince Shen, though older and afflicted with an eye disorder, would be preferable, and declared in the empress dowager's presence that Prince Duan was frivolous and unfit to rule the empire. His colleague Zeng Bu angrily ordered him to accept the empress dowager's decision. Zhao Ji took the throne as Emperor Huizong.

At first Huizong made Zhang Dun Duke of Shen, but because Zhang had opposed his accession and angered Empress Dowager Xiang, he was soon removed as chancellor. He was demoted to a minor registrar post in Lei Prefecture, then again to deputy military commissioner of Shu Prefecture and ordered to reside in Mu Prefecture, later moving to Huzhou. Zhang Dun died at his place of exile in Huzhou in 1106, the fourth year of Chongning, aged seventy-one, and was buried at Changxing. During the Zhenghe era he was posthumously granted Grand Preceptor and Duke of Wei. In 1135, the fifth year of Shaoxing, Emperor Gaozong reduced his posthumous official honors. During the Chunxi era of the Southern Song he was granted the posthumous name Zhongmin.

Major Activities

Political Activity

Zhang Dun was a central reformist figure in the intense factional conflicts of the middle and late Northern Song. During the Xining era he served as an important assistant to Wang Anshi, taking part in the formulation and implementation of the New Policies. He held major fiscal posts, including editor in the Three Fiscal Agencies Regulations Office, reviewing official for the Secretariat's revenue section, and State Finance Commissioner, and helped advance the reform program.

During the Yuanfeng era Zhang rose to Assistant Grand Councilor and Vice Director of the Chancellery, becoming the senior vice-chancellor and participating in the highest level of policy making. In 1085, when Emperor Shenzong was critically ill, Zhang joined Chancellor Wang Gui and others in settling the succession on Emperor Zhezong, helping stabilize the court.

During the Yuanyou era, when the conservative faction dismantled the New Policies, Zhang Dun remained one of the few senior officials at court to defend them. He repeatedly debated Sima Guang before the regent and analyzed the strengths and weaknesses of the Service Exemption Law and restored corvée service. He was demoted but did not abandon his position.

After becoming chancellor during Shaosheng, Zhang led the program of restoration, reviving major Xining policies and promulgating edicts on the ever-normal granaries and service exemption throughout the empire. He also launched sweeping attacks on former Yuanyou officials and promoted cases such as the Tongwenguan prison investigation. At the same time he strengthened frontier policy and pursued a hard line against Western Xia, producing several strategic military successes and extending Song control.

Frontier Expansion

While serving as inspection commissioner for northern and southern Jinghu during Xining, Zhang Dun directed policy toward non-Han communities in the Nanjiang and Beijiang regions, combining military expansion with pacification. The source credits him with establishing or reorganizing Yuan and Cheng prefectures and related local units, bringing 4,809 households and 260,000 mu of land under Song administration and extending the frontier by several hundred li. In 1077 he also suppressed unrest in an area at the intersection of modern Sichuan, Guizhou, and Guangxi and accepted the submission of forty-five prefectures. These policies strengthened central control in the southwest but, according to the source, also produced unrest in some regions because of their coercive methods.

Travels and Residences

Zhang Dun's career took him across much of the empire. Early posts included Shangluo in Shaanxi and Wujin in Jiangsu. During the Xining reforms he moved repeatedly between the capital at Bianjing and regional assignments. His southwestern frontier work brought him through areas of modern Hunan, Hubei, Chongqing, and Guizhou. During Yuanyou he was demoted to Ru Prefecture in Henan and served in Hangzhou, Zhejiang, before taking charge of Dongxiao Palace. During Shaosheng he governed from Bianjing as chancellor. After Huizong's accession he was exiled successively to Lei Prefecture in Guangdong, Shu Prefecture in Anhui, Mu Prefecture in Zhejiang, and finally Huzhou, Zhejiang, where he died.

Contemporary Associations

Zhang Dun had a close and complicated relationship with Su Shi. The two traveled together when young. On one occasion Zhang climbed a dangerous cliff to inscribe his name without showing fear, prompting Su Shi to predict that a man capable of such an act might also be capable of killing people. Their later political positions diverged, and while in power Zhang imposed severe demotions on Su. Yet when Su was pardoned and returning north, Zhang's son Zhang Yuan wrote to him, and Su replied in a conciliatory spirit, reflecting the complexity of the relationship between the two families.

Zhang Dun was closely associated with Wang Anshi, whose support made him a core member of the reform movement. He was also close to Lü Huiqing and was described as one of Lü's intimate associates, which later contributed to his own demotion. During Yuanyou he fought bitterly with Sima Guang. He served alongside Zeng Bu but clashed with him sharply over Emperor Huizong's succession. Zhang Dun's son Zhang Yuan was a student of Su Shi, further complicating relations between the Zhang and Su families.

Historical Assessment

Song and Contemporary Assessments

• History of Song placed Zhang Dun in its "Biographies of Treacherous Ministers" and accused him of fully restoring the Xining and Yuanfeng policies, driving out Yuanyou officials, opening frontier conflicts, and slandering Empress Dowager Xuanren. This Yuan-dynasty compilation reflected a mainstream official judgment inherited from the Southern Song.
• Lü Gongzhu acknowledged that some of Zhang Dun's arguments were worth adopting but criticized him for caring too much about winning and not enough about the overall dignity and interests of the court.
• Emperor Zhezong reportedly lamented that Zhang Dun had damaged his moral reputation in the affair of Empress Meng, suggesting that even Zhezong regarded Zhang's methods as excessively harsh.
• Zeng Bu's angry order that Zhang accept the empress dowager's decision during the Huizong succession dispute illustrates contemporary frustration with Zhang's obstinacy.

Song and Yuan Periods

• Southern Song scholars generally judged Zhang Dun negatively and often treated him as one of the figures responsible for the Northern Song's decline. Emperor Gaozong's posthumous demotion of Zhang in 1135 reflected the Southern Song court's rejection of Wang Anshi's reforms and the Shaosheng restoration.
• Zhu Xi and other Neo-Confucian scholars rated Zhang very poorly, treating him as a model treacherous minister and arguing that his government intensified factional conflict and damaged the foundations of the state.
• The Yuan compilers under Toqto'a placed Zhang in the "Treacherous Ministers" section of the History of Song, continuing the Southern Song judgment. The same work nevertheless acknowledged that he was learned, talented in writing, and exceptionally quick-witted.

Ming and Qing Periods

• Wang Fuzhi in Song Lun argued that Zhang's restoration had some merit in reviving the New Policies but that his excessive persecution of the conservative faction made factional conflict increasingly destructive.
• Qing scholars such as Qian Daxin began to soften the traditional judgment, drawing attention to Zhang's role in restoring reform policies and strengthening frontier defense and questioning whether inclusion among "treacherous ministers" was entirely fair.
• Zhao Yi in Notes on the Twenty-Two Histories showed some sympathy for Zhang's position in Northern Song factional conflict, arguing that although his methods were harsh, they were also shaped by the political environment of intense party struggle.

Modern Assessments

• With modern reassessments of Wang Anshi's reforms, views of Zhang Dun have also become more diverse. Some scholars regard him as a committed successor to Wang Anshi whose Shaosheng restoration revived and developed reform measures and contributed positively to the recovery of Northern Song state capacity.
• Some researchers emphasize that his campaigns against Western Xia produced substantial military results and strengthened frontier defense.
• Others stress the severity of his persecution of political opponents, the wide scope of prison cases, demotions, and collective punishment, and the role such actions played in deepening the destructive cycle of factionalism.
• Overall, modern scholarship, as summarized in the Chinese source, no longer treats Zhang simply as a "treacherous minister" but evaluates him through multiple dimensions including reform, factional politics, and frontier policy, seeing him as a highly capable but extreme and deeply controversial political figure.
