The Ming dynasty, which encompassed the reigns of 16 emperors, proved to be one of the stablest and longest ruling periods of Chinese history. Rulers of Korea, Mongolia, East Turkistan, Myanmar, Siam, and Nam Viet regularly acknowledged Ming overlordship, and at times tribute was received from as far away as Japan, Java and Sumatra, Sri Lanka and South India, the East African coast, the Persian Gulf region, and Samarkand. Modern Chinese honor the Ming emperors especially for having restored China’s international power and prestige, which had been in decline since the 8th century. The Ming emperors probably exercised more far-reaching influence in East Asia than any other native rulers of China, and their attitude toward the representatives of Portugal, Spain, Russia, Britain, and Holland who appeared in China before the end of their dynasty was a condescending one.

For the first time in Chinese history, the Ming rulers regularly adopted only one reign name (nianhao) each; the sole exception was the sixth emperor, who had two reigns separated by an interval of eight years. Because of this reign-name practice (which was perpetuated under the succeeding Qing dynasty), modern writers, confusingly but correctly, refer to the Wanli emperor, for example, by his personal name, Zhu Yijun; by his temple name, Shenzong; or sometimes, incorrectly but conveniently, simply as Wanli, as if the reign name were a personal name.

The Ming dynasty’s founder, the Hongwu emperor, is one of the strongest and most colorful personalities of Chinese history. His long reign established the governmental structure, policies, and tone that characterized the whole dynasty. After his death in 1398 his grandson and successor, the Jianwen emperor, trying to assert control over his powerful uncles, provoked a rebellion on the part of the prince of Yan and was overwhelmed in 1402. The prince of Yan took the throne as the Yongle emperor (reigned 1402–24) and proved to be vigorous and aggressive. He subjugated Nam Viet, personally campaigned against the reorganizing Mongols in the north, and sent large naval expeditions overseas, chiefly under the eunuch admiral Zheng He, to demand tribute from rulers as far away as Africa. He also returned the empire’s capital to Beijing, giving that city its present-day name.

For a century after the Yongle emperor, the empire enjoyed stability, tranquility, and prosperity. But state administration began to suffer when weak emperors were exploitatively dominated by favored eunuchs: Wang Zhen in the 1440s, Wang Zhi in the 1470s and ’80s, and Liu Jin from 1505 to 1510. The Hongxi (reigned 1424–25), Xuande (1425–35), and Hongzhi (1487–1505) emperors were nevertheless able and conscientious rulers in the Confucian mode. The only serious disruption of the peace occurred in 1449 when the eunuch Wang Zhen led the Zhengtong emperor (first reign 1435–49) into a disastrous military campaign against the Oirat (western Mongols). The Oirat leader Esen Taiji ambushed the imperial army, captured the emperor, and besieged Beijing. The Ming defense minister, Yu Qian, forced Esen to withdraw unsatisfied and for eight years dominated the government with emergency powers. When the interim Jingtai emperor (reigned 1449–57) fell ill in 1457, the Zhengtong emperor, having been released by the Mongols in 1450, resumed the throne as the Tianshun emperor (1457–64). Yu Qian was then executed as a traitor.

The Zhengde (reigned 1505–21) and Jiajing (1521–1566/67) emperors were among the less-esteemed Ming rulers. The former was an adventure-loving carouser, the latter a lavish patron of Daoist alchemists. For one period of 20 years, during the regime of an unpopular grand secretary named Yan Song, the Jiajing emperor withdrew almost entirely from governmental cares. Both emperors cruelly humiliated and punished hundreds of officials for their temerity in remonstrating.

China’s long peace ended during the Jiajiang emperor’s reign. The Oirat, under the vigorous new leadership of Altan Khan, were a constant nuisance on the northern frontier from 1542 on; in 1550 Altan Khan raided the suburbs of Beijing itself. During the same era, Japan-based sea raiders repeatedly plundered China’s southeastern coast. Such sea raiders, a problem in Yuan times and from the earliest Ming years, had been suppressed during the reign of the Yongle emperor, when Japan’s Ashikaga shogunate offered nominal submission to China in exchange for generous trading privileges. However, changes in the official trade system eventually provoked new discontent along the coast, and during the 1550s corsair fleets looted the Shanghai-Ningbo region almost annually, sometimes sending raiding parties far inland to terrorize cities and villages throughout the whole Yangtze delta. Although coastal raiding was not totally suppressed, it was brought under control in the 1560s. Also in the 1560s Altan Khan was repeatedly defeated, so that he made peace in 1571. For the next decade, during the last years of the Longqing emperor (reigned 1566/67–1572) and the early years of the Wanli emperor (1572–1620), the government was highly stable. The court was dominated by the outstanding grand secretary of Ming history, Zhang Juzheng, and capable generals such as Qi Jiguang restored and maintained effective military defenses.

In 1592, when Japanese forces under Toyotomi Hideyoshi invaded Korea, Ming China was still strong and responsive enough to campaign effectively in support of its tributary neighbor. But the Korean war dragged on indecisively until 1598, when Hideyoshi died and the Japanese withdrew. It made heavy demands on Ming resources and apparently precipitated a military decline in China.

The reign of the Wanli emperor was a turning point of Ming history in other regards as well. Partisan wrangling among civil officials had flared up in the 1450s in reaction to Yu Qian’s dominance and again in the 1520s during a prolonged “rites controversy” provoked by the Jiajing emperor on his accession; after Zhang Juzheng’s death in 1582, it became the normal condition of court life. Through the remainder of the Wanli emperor’s long reign, a series of increasingly vicious partisan controversies absorbed the energies of officialdom, while the harassed emperor abandoned more and more of his responsibilities to eunuchs. The decline of bureaucratic discipline and morale continued under the Taichang emperor, whose sudden death after a reign of only one month in 1620 fueled new conflicts. The Tianqi emperor (reigned 1620–27) was too young and indecisive to provide needed leadership. In 1624 he finally gave almost totalitarian powers to his favorite, Wei Zhongxian, the most notorious eunuch of Chinese history. Wei brutally purged hundreds of officials, chiefly those associated with a reformist clique called the Donglin party, and staffed the government with sycophants.

A new threat had in the meantime appeared on the northern frontier. The Manchu, quiet occupants of far eastern Manchuria from the beginning of the dynasty, were aroused in 1583 by an ambitious young leader named Nurhachi. During the Wanli emperor’s latter years, they steadily encroached on central Manchuria. In 1616 Nurhachi proclaimed a new dynasty, and overwhelming victories over Ming forces in 1619 and 1621 gave him control of the whole northeastern segment of the Ming empire, south to the Great Wall at Shanhaiguan.

The Chongzhen emperor (reigned 1627–44) tried to revitalize the deteriorating Ming government. He banished Wei Zhongxian but could not quell the partisan strife that was paralyzing the bureaucracy. The Manchu repeatedly raided within the Great Wall, even threatening Beijing in 1629 and 1638. Taxes and conscriptions became increasingly oppressive to the Chinese population, and banditry and rebellions spread in the interior. The Ming government became completely demoralized. Finally, a domestic rebel named Li Zicheng captured the capital in April 1644, and the Chongzhen emperor killed himself. The Ming commander at Shanhaiguan accepted Manchu help in an effort to punish Li Zicheng and restore the dynasty, only to have the Manchu seize the throne for themselves.

Ming loyalists ineffectively resisted the Qing (Manchu) dynasty from various refuges in the south for a generation. Their so-called Nan (Southern) Ming dynasty principally included the prince of Fu (Zhu Yousong, reign name Hongguang), the prince of Tang (Zhu Yujian, reign name Longwu), the prince of Lu (Zhu Yihai, no reign name), and the prince of Gui (Zhu Youlang, reign name Yongli). The loyalist coastal raider Zheng Chenggong (Koxinga) and his heirs held out on Taiwan until 1683.
