Quizplus · Accepted Answer

The Opium War, which began in 1839, forced China to open its borders to European influences. Britain's victory in the war enabled them to impose the Treaty of Nanking, which gave Britain control of Hong Kong and opened up five Chinese ports to European trade. This marked the beginning of the "Unequal Treaties" era, in which European powers forced China to make concessions and open up to foreign influence.
