Jianwen Emperor
The Jianwen Emperor, personal name Zhu Yunwen, was the second emperor of the Ming dynasty, reigning from 1398 to 1402. Zhu Yunwen's father was Zhu Biao, the eldest son and heir apparent of the Hongwu Emperor, the founder of the Ming dynasty. Zhu Biao died in 1392, after which the Hongwu Emperor named Zhu Yunwen as his successor. Zhu Yunwen ascended the throne after the Hongwu Emperor's death in June 1398.
Upon his accession, the Jianwen Emperor immediately began revising the Hongwu Emperor's reforms, with the most significant change being the attempt to limit or eliminate the power of princes who were sons of the Hongwu Emperor. Zhu Di, the most powerful of these princes, rebelled against the Jianwen Emperor in 1399. He did this under the pretext of acting against allegedly corrupt court officials who had influenced the Emperor, following the Emperor's order for the imprisonment of Zhu Di's own followers. This sparked a civil war known as the Jingnan campaign, which Zhu Di framed as an effort to eliminate disorder. In 1402, Zhu Di captured the capital of Nanjing, and the imperial palace was burned to the ground. Even though three bodies were found at the burnt palace and were later announced to be those of the Emperor, his wife, and their eldest son, rumors of the Emperor's survival and refuge in a Buddhist monastery emerged. Zhu Di ascended the throne as the Yongle Emperor. He abolished the Jianwen Emperor's reforms and declared his reign illegitimate, thus abolishing the Jianwen era and extending the era of Hongwu to 1402. It was not until 1595 that the Jianwen Emperor's era and imperial title were restored by the Wanli Emperor.
Early life
Zhu Yunwen, the future Jianwen Emperor, was born on 5 December 1377 during the reign of his grandfather the Hongwu Emperor, who was the founder of the Ming dynasty. He was the second son of Zhu Biao, who was the Emperor's eldest son and heir apparent. Zhu Yunwen's mother was Lady Lü. In 1382, the death of Zhu Yunwen's elder brother left him as the eldest surviving son of Zhu Biao. According to historian Chan Hok-lam, he was a mature and straightforward child, earning the favor of his grandfather.In May 1392, Zhu Biao died at the age of thirty-seven after several months of illness, whereupon the court discussed his succession. The primogeniture viewpoint advocated by scholars from the Hanlin Academy and high officials prevailed, and as the eldest surviving son, Zhu Yunwen was named the new heir on 28 September 1392. He spent the next six years carefully preparing for his future role as emperor. Chan describes Zhu Yunwen as bookish and gentle, inheriting his father's moderate and reflective temperament. As heir, he criticized the Hongwu Emperor's excessively harsh laws and penal pronouncements, advocating for their abolition. Later historical accounts, often produced by scholars sympathetic to the deposed emperor, present him as a ruler who adhered to Confucian values, known for his virtuous character and his practice of Ren and Filial piety. The Hongwu Emperor had doubts about his grandson's ability to rule, believing he lacked toughness. To ensure a smooth transition for his heir, the Emperor carried out purges of officials in 1393 after the discovery of Lan Yu's conspiracy of treason, a campaign that resulted in the execution and banishment of thousands of people.
Accession
The Hongwu Emperor died on 24 June 1398 and on 30 June 1398, Zhu Yunwen ascended the throne. The era name of his reign, Jianwen, means "establishing civility" and represents a sharp change in tone from Hongwu, the era name of his grandfather's reign. Consistent with his Confucian principles, the Jianwen Emperor was deeply concerned about the harshness of his grandfather's policies, and as a result, he aimed to bring about significant changes in the political landscape. He relied on Confucian scholars such as Huang Zicheng, Qi Tai, and Fang Xiaoru for guidance, all of whom were idealistic reformers but lacked practical experience in governing the country.Reforms
During the reign of the Jianwen Emperor, the civilian part of the administration gained more influence. The ministers were elevated from the second rank to the first in the hierarchy of rank classes, placing them on equal footing with the highest-ranking generals. After the abolition of the Central Secretariat in 1380, there had been no central office in the Ming administration to coordinate the work of ministries and other civil offices. As a result, all of these offices were directly under the Emperor's control. The Jianwen Emperor relied on Huang, Qi, and Fang to lead the government. Although they effectively acted as chancellors, they did not hold the official title. This was a formal gesture to adhere to the Hongwu Emperor's Ancestral Injunctions, which had strictly forbidden the restoration of the chancellery due to concerns about the potential threat from the chancellor's authority and autonomy.The number of departments and officials in the ministries was changed, and the offices and personnel of the Hanlin Academy and the Imperial University were substantially expanded under the Jianwen Emperor. He also strengthened the influence of Hanlin scholars in educating princes by creating new positions in the Household Administration of the Heir Apparent. A series of changes was made to the titles and structure of offices, following the patterns of the ancient Zhou dynasty.
The Jianwen Emperor reduced the excessive land taxes imposed on Jiangnan, specifically Suzhou and Songjiang prefectures. For example, Suzhou prefecture, despite accounting for merely 1.1% of the empire's land, was subjected to a tax of 2.81 million dan of grain in 1393. This amount represented a disproportionate 9.5% of the empire's total tax of 29.4 million dan. In 1400, land taxes in Nanzhili and Zhejiang were curtailed. The following year, the Emperor further reformed the system by limiting the amount of tax-exempt land for Taoist and Buddhist clergy, compelling them to surrender any land exceeding a specified amount for redistribution to the needy. However, the government did not have sufficient time to fully implement these comprehensive changes before its fall.
Reduction of the princes' power
The Jianwen government aimed to reduce the influence of the Emperor's uncles, the sons of the Hongwu Emperor, especially Zhu Di, Prince of Yan; Zhu Su, Prince of Zhou; Zhu Gui, Prince of Dai; Zhu Bo, Prince of Xiang; Zhu Fu, Prince of Qi; and Zhu Pian, Prince of Min. Their father had granted them the title of prince, along with significant income and privileges. They were stationed in various provinces and each commanded three auxiliary army units, which could range from 3,000 to 15,000 men. The most powerful and eldest among them was Zhu Di, the fourth son of the Hongwu Emperor. The princes saw the Jianwen Emperor's efforts as a personal threat and a violation of the Hongwu Emperor's Ancestral Injunctions, which everyone, including the Emperor, was obliged to obey.The policy of "reducing the feudatories" was supported by Qi and Huang, who cited past dynastic experiences, such as the Rebellion of the Seven States during the Han dynasty. Princedoms were either directly abolished or had their powers limited for both real and perceived offenses. The government also forbade the princes from participating in public affairs.
The first victim of the new order was Zhu Su, based in Kaifeng, a city in central China, and a close friend of Zhu Di. In the fall of 1398, the Jianwen Emperor stripped him of his title and exiled him to the southeastern Chinese province of Yunnan. However, Zhu Su was subsequently brought back to Nanjing, where his coerced testimony amplified charges of a princely conspiracy. This resulted in the house arrest of Zhu Gui in Datong in February 1399, and directly caused Zhu Bo to set fire to his own palace in Jingzhou, burning himself and his family to death on 1 June 1399. In the following two months, in June and July, Zhu Fu and Zhu Pian were also stripped of their titles. The main target of the government's measures was Zhu Di. He was based in Beijing and had shown himself to be a capable military leader and energetic administrator during campaigns against the Mongols. After he was passed over as successor in 1392, he considered himself unjustly neglected.
Civil war
From 1399 to 1402, the Jianwen Emperor was engaged in a civil war against his uncle, Zhu Di, which nearly led to the destruction of the newly established dynasty. The conflict ended when Zhu Di's army overwhelmed the capital; he then ascended the throne as the Yongle Emperor, while the Jianwen Emperor was reported to have died in the palace fire.Conflict with Zhu Di
The Jianwen Emperor's government was cautious towards Zhu Di, which gave him the opportunity to prepare and gather forces, although his power was systematically limited. Fifteen thousand men under Zhu Di's command were transferred outside of Beijing. Meanwhile, several military units with ties to him were redeployed to distant locations, and loyalist commanders were stationed at key strategic points surrounding his princedom.In June 1399, the Emperor finally granted Zhu Di's request to return his sons, who had been in Nanjing since the Hongwu Emperor's funeral, to Beijing. This event removed Zhu Di's inhibitions. The immediate pretext for his rebellion was the arrest of two of his lower officials on charges of sedition. With the support of Beijing's provincial dignitaries, Zhu Di responded by launching military offensives against several neighboring counties and prefectures around Beijing, marking the beginning of the war later called the Jingnan campaign—a campaign to clear away disorders.
Zhu Di justified his actions by stating his desire to end internal disorder and confusion, defend the Hongwu Emperor's Ancestral Injunctions that defined the duties of princes, and honor his deceased father. He accused the Jianwen Emperor and his ministers of falsely charging him with making military preparations against the throne. He presented his rebellion as a reasonable act of self-defense. He also stated that he had no interest in the throne, but as the eldest surviving son of the deceased founder of the dynasty, he felt obligated to restore the law and legality that had been subverted by the Emperor's advisors and ministers, whom he described as treacherous and wicked.
