Question

why was the opium war called so and what were its major consequences

Answer 1

The Opium Wars were two wars in the mid-19th century involving Anglo-Chinese disputes over British trade in China and China's sovereignty. The disputes included the First Opium War (1839–1842) and the Second Opium War (1856–1860). The wars and events between them weakened the Qing dynasty and reduced China's separation from the rest of the world.[
