Late Qing decline & the 1911 Revolution
The collapse of the Qing dynasty from the Opium Wars to the 1911 Xinhai Revolution and the founding of the Republic in 1912.
The structural roots of decline
The Qing dynasty (1644-1912), the last imperial dynasty of China, entered terminal decline through a compounding sequence of foreign defeats, fiscal exhaustion, and ideological erosion. The First Opium War (1839-1842), provoked by the Daoguang Emperor's appointment of Lin Zexu to suppress the British opium trade at Canton, ended in the Treaty of Nanjing (29 August 1842) — the first of the 'unequal treaties.' It ceded Hong Kong Island, opened five treaty ports, fixed a 5 percent tariff, and imposed an indemnity of 21 million silver dollars. The Treaty of the Bogue (1843) added extraterritoriality and most-favoured-nation status.
The Second Opium War (1856-1860) deepened the humiliation. The Treaties of Tianjin (1858) and the Convention of Peking (1860), signed after the Anglo-French sack of the Yuanmingyuan (Old Summer Palace) in October 1860, opened the interior, legalised opium, and ceded Kowloon. Russia simultaneously extracted the Amur and Ussuri territories through the Treaties of Aigun (1858) and Peking (1860).
Internal rebellion and the Self-Strengthening response
The Taiping Rebellion (1850-1864), led by Hong Xiuquan from his Heavenly Kingdom at Nanjing, cost an estimated 20-30 million lives and was suppressed not by Manchu banner armies but by Han provincial militias — Zeng Guofan's Xiang Army and Li Hongzhang's Huai Army. This shift of military and fiscal power to Han regional governors fatally weakened central Manchu authority.
The Self-Strengthening Movement (Ziqiang yundong, c. 1861-1895), under the slogan 'Chinese learning as the base, Western learning for use' (zhongti xiyong), built arsenals such as the Jiangnan Arsenal (1865) and the Fuzhou Navy Yard. Its limits were exposed decisively in the First Sino-Japanese War (1894-1895). The Treaty of Shimonoseki (17 April 1895) ceded Taiwan and the Penghu Islands, recognised Korean independence, paid 200 million taels, and confirmed that a reformed Meiji Japan had eclipsed China.
Failed reform and the scramble for concessions
Defeat triggered the Hundred Days' Reform (11 June - 21 September 1898), in which the Guangxu Emperor, advised by Kang Youwei and Liang Qichao, decreed sweeping institutional change. Empress Dowager Cixi's coup of 21 September 1898 reversed it, executed the 'Six Gentlemen,' and placed Guangxu under house arrest. The anti-foreign Boxer Uprising (1899-1901), initially tolerated by Cixi, ended in occupation of Beijing by the Eight-Nation Alliance and the punitive Boxer Protocol (7 September 1901), which imposed an indemnity of 450 million taels. The belated New Policies (Xinzheng) after 1901 — abolishing the imperial examination system in 1905 and promising a constitution — came too late to save the dynasty.
