Opium Wars - Imperialism in China

In Asia Britian had a ton of Opium. With that opium they traded with the chinese and the chinese got really additcted to it. Too much opium can harm the body so the government closed the ports for the Britsh from docking. This led to the Opium War. In the end of this war china was forced to open their ports for the Britsh to dock their boats for trading with the chinese again because they lost the war against them.
