Answer:
The Opium War, usually the Opium War refers to the First Opium War, which the British often refer to as the First Sino-British War or "Trade War", which was an unjust war of aggression launched by Britain against China from 1840 to 1842, and also the beginning of China's modern history of humiliation.
In 1840 (the twentieth year of Daoguang), the British government decided to send an expeditionary force to invade China under the pretext of Lin Zexu's Humen tobacco sales. In June 1840, 47 British ships and 4,000 army personnel, led by Rear Admiral George Yilu and Yi Lu, the commercial supervisor in China, arrived outside the mouth of the Pearl River in Guangdong province, blockaded Haikou, and the Opium War began.
The Opium War ended with China's defeat and the cession of land in reparations. China and Britain signed the Treaty of Nanking, the first unequal treaty in Chinese history. China began to cede land, pay indemnities, and agree on tariffs to foreign countries, which seriously endangered China's sovereignty, began to degenerate into a semi-colonial and semi-feudal society, lost its independent and autonomous status, and promoted the disintegration of the small-scale peasant economy. At the same time, the Opium War also opened a new chapter in the history of the resistance of the Chinese people to foreign aggression in modern times.
