The Treaty of Nanking marked the end of the First Opium War, ceding Hong Kong to Britain and opening China to foreign trade under unequal terms.
The Treaty of Nanking, signed in 1842, concluded the First Opium War between Qing China and Great Britain. This treaty marked a significant shift in Sino-British relations, as it imposed unequal terms on China, including the cession of Hong Kong to Britain and the opening of five Chinese ports to British trade and residence. The treaty also established a 'fair and reasonable' tariff and granted British citizens extraterritorial rights in China. The Treaty of Nanking is often cited as the first of the 'unequal treaties' that eroded China's sovereignty and marked the beginning of the 'Century of Humiliation.' Its provisions had long-lasting impacts on China's political landscape and its relations with Western powers, setting a precedent for further concessions and treaties in the years that followed.
