Pegatina Seal of the Great Qing Empire

The Qing dynasty (/tʃɪŋ/ CHING), officially the Great Qing, was a Manchu-led imperial dynasty of China and an early modern empire in East Asia. Being the last imperial dynasty in Chinese history, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. At its height of power, the empire stretched from the Sea of Japan in the east to the Pamir Mountains in the west, and from the Mongolian Plateau in the north to the South China Sea in the south. Originally emerging from the Later Jin dynasty founded in 1616 and proclaimed in Shenyang in 1636, the dynasty seized control of the Ming capital Beijing and North China in 1644, traditionally considered the start of the dynasty's rule. The dynasty lasted until the Xinhai Revolution of October 1911 led to the abdication of the last emperor in February 1912. The multi-ethnic Qing dynasty assembled the territorial base for modern China. The Qing controlled the most territory of any dynasty in Chinese history, and in 1790 represented the fourth-largest empire in world history to that point. With over 426 million citizens in 1907, it was the most populous country in the world at the time. Nurhaci, leader of the Jianzhou Jurchens and House of Aisin-Gioro who was also a vassal of the Ming dynasty, unified Jurchen clans (known later as Manchus) and founded the Later Jin dynasty in 1616, renouncing the Ming overlordship. As the founding Khan of the Manchu state he established the Eight Banners military system, and his son Hong Taiji was declared Emperor of the Great Qing in 1636. As Ming control disintegrated, peasant rebels captured Beijing as the short-lived Shun dynasty, but the Ming general Wu Sangui opened the Shanhai Pass to the Qing army, which defeated the rebels, seized the capital, and took over the government in 1644 under the Shunzhi Emperor and his prince regent. While the Qing became a Chinese empire, resistance from Ming rump regimes and the Revolt of the Three Feudatories delayed the complete conquest until 1683, which marked the beginning of the High Qing era. As an emperor of Manchu ethnic origin, the Kangxi Emperor (1661–1722) consolidated control, relished the role of a Confucian ruler, patronised Buddhism (including Tibetan Buddhism), encouraged scholarship, population and economic growth. Han officials worked under or in parallel with Manchu officials. To maintain prominence over its neighbors, the Qing leveraged and adapted the traditional tributary system employed by previous dynasties, enabling their continued predominance in affairs with countries on its periphery like Joseon Korea and the Lê dynasty in Vietnam, while extending its control over Inner Asia including Tibet, Mongolia, and Xinjiang. The Qing dynasty reached its apex during the reign of the Qianlong Emperor (1735–1796), who led the Ten Great Campaigns of conquest, and personally supervised Confucian cultural projects. After his death, the dynasty faced internal revolts, economic disruption, official corruption, foreign intrusion, and the reluctance of Confucian elites to change their mindset. With peace and prosperity, the population rose to 400 million, but taxes and government revenues were fixed at a low rate, soon leading to a fiscal crisis. Following China's defeat in the Opium Wars, Western colonial powers forced the Qing government to sign unequal treaties, granting them trading privileges, extraterritoriality and treaty ports under their control. The Taiping Rebellion (1850–1864) and the Dungan Revolt (1862–1877) in western China led to the deaths of over 20 million people, from famine, disease, and war. The Tongzhi Restoration in the 1860s brought vigorous reforms and the introduction of foreign military technology in the Self-Strengthening Movement. Defeat in the First Sino-Japanese War (1894–1895) led to loss of suzerainty over Korea and cession of Taiwan to the Empire of Japan. The ambitious Hundred Days' Reform in 1898 proposed fundamental change, but was poorly executed and terminated by the Empress Dowager Cixi (1835–1908) in the Wuxu Coup. In 1900, anti-foreign Boxers killed many Chinese Christians and foreign missionaries; in retaliation, the Eight-Nation Alliance invaded China and imposed a punitive indemnity. In response, the government initiated unprecedented fiscal and administrative reforms, including elections, a new legal code, and the abolition of the imperial examination system. Sun Yat-sen and revolutionaries debated reform officials and constitutional monarchists such as Kang Youwei and Liang Qichao over how to transform the Manchu-ruled empire into a modernised Han state. After the deaths of the Guangxu Emperor and Cixi in 1908, Manchu conservatives at court blocked reforms and alienated reformers and local elites alike. The Wuchang Uprising on 10 October 1911 led to the Xinhai Revolution. The abdication of the Xuantong Emperor on 12 February 1912 brought the dynasty to an end.
