Opium war- Imperialism in china

The Opium War was a war between England and China. They fought in during 1839 to 1842. China lost the war because the British had better weapons, and steam power, which China didn't have. For years, China didn't want to trade because they thought they had everything they needed. China used to use opium as treatments for diseases and sicknesses. The Chinese had put opium in the green tea and it became very popular. The British started putting opium with tobacco so then it was able to smoke it.
