Opium Wars - Imperialism in China

The Opium War started when the British wanted to trade with China but they refused to trade with westerners. The Chinese were also very isolated and thought they were better than everyone. The British wanted tea from the Chinese and since they refused to trade they came up with a plan to make them trade. The British started giving Opium (drug) to the Chinese which they became addicted and had to trade with the British cause they wanted more.

Later on the British stopped trading Opium and told the Chinese tot trade with them and they refused again. So the British declared war on China and they defeated them because Chinese weren't as advance as the British were military wise.
