Qing China entered the nineteenth century as one of the wealthiest and most populous states on Earth and ended it a fraction of that stature, humbled by foreign powers it had dismissed as tributary barbarians only decades before. The turning point was the First Opium War of 1839 to 1842, fought after the Qing government tried to suppress the British opium trade that was draining Chinese silver and addicting a growing share of its population; British naval and military superiority defeated Qing forces decisively, and the resulting 1842 Treaty of Nanjing, the first of what Chinese historiography calls the unequal treaties, ceded Hong Kong to Britain, opened five treaty ports to foreign trade, and imposed indemnities and extraterritorial legal privileges for foreign nationals that other powers, France, the United States, later Japan and Germany, soon extracted for themselves as well. A Second Opium War in 1856 to 1860 extended those concessions further, and the internal Taiping Rebellion of 1850 to 1864, one of the deadliest conflicts in human history with death tolls estimated in the tens of millions, nearly toppled the dynasty from within at the same time it was losing ground to foreign powers from without. Encyclopaedia Britannica traces the compounding damage through the rest of the century, further territorial losses, defeat by a modernizing Japan in 1894 to 1895, the 1900 Boxer Rebellion and its punitive foreign occupation of Beijing, each crisis further weakening a central government whose finances and legitimacy foreign indemnities and internal rebellion had already hollowed out. The Qing survived, in weakened form, into the twentieth century, but the 1911 Revolution and the 1912 abdication of the child emperor Puyi closed a dynasty whose final decades had been defined by retreat rather than the expansion of its earlier centuries.
