The first Opium War was a battle between which two countries?

The first Opium War was a conflict between Britain and China, occurring from 1839 to 1842. The war arose primarily due to trade imbalances, particularly concerning the opium trade, where Britain exported opium to China, leading to widespread addiction, social issues, and economic problems in China. The conflict led to significant concessions from China, including the Treaty of Nanking, which favored British trade interests.
