1839–1860
Two wars in which Britain, joined by France in the second, used military force to expand commerce and diplomatic access in Qing China after Chinese officials tried to suppress the illegal opium trade. The 1842 Treaty of Nanjing opened treaty ports and ceded Hong Kong but did not legalize opium; legalization followed the Second Opium War through the 1858 treaty-and-tariff settlement. The unequal treaties imposed new privileges on foreign powers and became central to Chinese memories of nineteenth-century imperial coercion.
