Opium Wars - Imperialism in China

The Opium war was during the Imperialism in China. The western Europeans were still exploring places, trying to find new resources. In China, they've found their tea and they loved it. The British only had one port in China. The British didn't like it, so they decided to trade Opium to the Chinese people for their tea. The people in China realized that it was a dangerous drug and they make it illegal, and whoever uses it can get killed. Afterward, China destroyed the Opium and banned the English men from China. This caused British to attacked China & the Britain won the war. China was so far behind from the new advanced technology & that was the main cause of why they lost. China's defeat by Britain made them sign a treaty.
