Destruction of opium at Humen

1839 Chinese destruction of illegal opium seized from British traders, which led to the First Opium War

The destruction of opium at Humen began on 3 June 1839, lasted for 23 days, and involved the destruction of 1,000 long tons (1,016 t) of illegal opium seized from British traders under the supervision of Lin Zexu, an Imperial Commissioner of Qing China. Conducted on the banks of the Pearl River outside Humen Town, Dongguan, China, the action provided casus belli for Great Britain to declare war on Qing China. What followed is now known as the First Opium War (1839–1842), a conflict that initiated China's opening for trade with foreign nations under a series of treaties with the western powers.
