The Wanli Emperor (4 September 1563 – 18 August 1620), personal name Zhu Yijun, was the 14th emperor of the Ming dynasty of China, reigning from 1572 to 1620. He succeeded his father, the Longqing Emperor.
The Wanli Emperor ascended the throne at the age of nine. During the first ten years of his reign, Grand Secretary Zhang Juzheng effectively led the government, while the Emperor's mother, Lady Li, and the eunuch Feng Bao also played significant roles. The country experienced economic and military prosperity, reaching a level of power not seen since the early 15th century. The Emperor held great respect and appreciation for Zhang Juzheng, but as time passed, various factions within the government openly opposed Zhang, and the Emperor started to consider his influential position a burden. After Zhang died in 1582, the Emperor made significant changes to his administrative arrangements.
Ming China saw three major campaigns in the last decade of the 16th century. A Ming force of 40,000 soldiers had quelled a large rebellion in Ningxia by October 1592, allowing the Ming to shift their focus to Korea. Concurrently, Japan invaded Korea, leading to a joint Korean-Chinese force, including 40,000 Ming soldiers, pushing the Japanese out of most of Korea and forcing them to retreat to the southeast coast by 1593. In 1597, a second Japanese invasion was thwarted, and the suppression of the Yang Yinglong rebellion in southwest China concluded in a few months from 1599 due to Ming forces concentrating there amidst the ongoing war with Japan. In the final years of the Wanli era, the Jurchens grew stronger on the northeastern frontiers and posed a significant threat. In 1619, they defeated the Ming armies in the Battle of Sarhu and captured part of Liaodong.
Over time, the Emperor grew increasingly disillusioned with the constant demoralizing attacks and counterattacks from officials, causing him to become increasingly isolated. In the 1580s and 1590s, he attempted to promote his third son, Zhu Changxun, as heir to the throne, but many officials supported his eldest son, Zhu Changluo. This led to ongoing conflicts between the Emperor and his ministers for over fifteen years. Eventually, the Emperor appointed Zhu Changluo as heir in 1601, and Zhu Changluo later succeeded his father as the Taichang Emperor in 1620. In 1596, the Wanli Emperor attempted to establish a parallel administration composed of eunuchs, separate from the officials who had traditionally governed the empire, but this effort was abandoned in 1606. The governance of the country remained in the hands of Confucian intellectuals, who were often embroiled in disputes with each other. The opposition Donglin movement continued to criticize the Emperor and his followers, while pro-government officials were divided based on their regional origins.
Zhu Yijun, the future Wanli Emperor, was born on 4 September 1563 during the reign of his grandfather, the Jiajing Emperor, who ruled China's Ming dynasty from 1521 to 1567. His father, Zhu Zaiji, was the heir to the throne, and his mother, Lady Li, was one of Zhu Zaiji's concubines. He had two older brothers, both of whom died in early childhood before 1563, and a younger brother, Zhu Yiliu (朱翊鏐; 1568–1614), who was made Prince of Lu in 1571. Zhu Zaiji ascended the throne as the Longqing Emperor in 1567, and designated Zhu Yijun as his heir in 1568. On 5 July 1572, the Longqing Emperor died at the age of 35, and Zhu Yijun succeeded his father two weeks later on 19 July 1572. He adopted the era name Wanli, which means "ten thousand years (of rule)".
Early reign: Zhang Juzheng's leadership (1572–1582)
At the end of the Longqing Emperor's reign, the government was led by Senior Grand Secretary Gao Gong. Shortly after the Wanli Emperor's accession, an alliance between the influential eunuch Feng Bao and Grand Secretary Zhang Juzheng succeeded in removing Gao. Zhang replaced Gao and remained in power until his death in 1582. Seeking to "enrich the country and strengthen the army", Zhang promoted Legalist rather than Confucian policies. He centralized government, expanded imperial authority at the expense of local interests, streamlined administration, and strengthened the military. His reforms included closing local academies and placing investigating censors under the Grand Secretariat's control. The Empress Dowager served as regent, and she and Feng Bao supported Zhang. Zhang selected his colleagues in the Grand Secretariat and extended informal influence over the Ministry of Rites and the Censorate through loyal appointments in central and regional offices. Although he lacked formal authority to issue orders, this arrangement gave him considerable power. He also redirected censors from personal vendettas toward tax collection and suppressing banditry. The efficiency of Ming administration improved markedly between 1572 and 1582, reaching a level seen only in the dynasty's early years.
Zhang implemented a series of reforms, including the conversion of tax payments from goods to silver (the single whip reform), changes to the old military field system, and revisions to county accounts on corvée labor, fees, and surcharges between 1572 and 1579. A new cadastre was compiled from 1580 to 1582, and these reforms were formalized empire-wide through revised lists of taxpayers' obligations, unified into payments in silver. As part of the administrative reforms, unnecessary activities were abolished or limited, state support for Confucian students was reduced, and provincial authorities were instructed to require only one-third of the former corvée labor. Postal services were also curtailed. Despite these measures, tax rates remained unchanged and arrears were strictly enforced, enabling Zhang to generate a surplus of income over expenditure. This was a notable achievement, as the Ming state usually lacked financial reserves in the 16th century. Improved savings and tax collection produced substantial reserves: by 1582, granaries around the capital held nine years' worth of grain; the Taicang treasury (太倉庫) contained 6 million liang (about 223 tons) of silver; the Court of the Imperial Stud (太僕寺) held another 4 million; and 2.5 million was stored in Nanjing. Smaller reserves also existed in Sichuan, Zhejiang, and Guangxi. Despite these successes, Zhang introduced no institutional innovations, instead improving existing procedures under the slogan of restoring the order of the early Ming period.
As a proponent of peace with the Mongols, Zhang rejected the proposal of Minister of War Tan Lun for a pre-emptive strike against them. Instead, he ordered Qi Jiguang, commander of the northeastern border, to maintain an armed peace. This decision not only allowed for a reduction in the border army, but also resulted in the return of surplus soldiers to their family farms. Zhang rejected the notion that military affairs were less important than civilian ones, and challenged the dominance of civilian dignitaries over military leaders. He appointed capable military leaders such as Qi Jiguang, Wang Chonggu (王崇古), Tan Lun, Liang Menglong (梁夢龍), and Li Chengliang to positions of responsibility. Additionally, he implemented a combination of defensive and offensive measures to strengthen border defenses and fostered peaceful relations with neighboring countries by opening border markets, particularly in the northwest.
Zhang's actions were within the bounds of existing legislation, but critics viewed them as an abuse of power to promote his followers and exert illegitimate pressure on officials. Open criticism was rare until his father's death in 1577. According to the law, Zhang was supposed to leave office due to mourning, but the Emperor chose to keep him in office. This was not unprecedented, but he was widely criticized for disrespecting his parents. Despite the fact that the most vocal critics were punished with beatings, Zhang's reputation was damaged. In an attempt to suppress opposition, Zhang then ordered all high-ranking officials to submit evaluations of their own performance, resulting in the elimination of around fifty opponents.
