The Opium Wars were two minor wars fought between China and Great Britain (primarily) over the opium trade in China. They took place during the middle of the 1800s near the end of the Qing Dynasty. Some historians consider the Opium Wars to be the start of the modern era in China.
After winning the war, the British forced the Chinese to sign the Treaty of Ranking. The treaty reestablished trade between the countries and opened up five trade ports to Britain. It also forced China to pay $21 million in reparations and gave Britain control of the city of Hong Kong
At the Convention of Peking in 1860, the Chinese agreed to sign a treaty with Britain and France. The treaty legalized the opium trade, established freedom of religion in China, forced China to pay France and Britain reparations, and opened a new trade port.
