Why were there Opin Wars?

Answer 1

The Opium Wars were two wars fought in the mid-1800s that were the climax of a long dispute between Britain and China. In the second, France fought alongside Britain. This dispute was around the opium trade which was perceived from a variety of cultural and economic vantage points, as is often the case with global economic conflicts. The Chinese Emperor (Dao Guang) had banned opium in China due to its harmful effects on Chinese citizens and its degenerative impact on the Chinese culture; the British Empire, however, saw opium as a profitable good for commercial trade, as its import would help balance Britain's huge trade deficit with China. The Opium Wars and the unequal treaties signed afterwards led in part to the downfall of the Chinese Empire, as many countries followed Britain and forced more treaties to increase trade within China.

Answer 2

You mean Opium Wars?? The British wanted to trade with China, but China wasn't really interested in any of the worthless crap that the Brits had. So, the Brits introduced opium to the Chinese and used the population's growing addictions to strongarm the Chinese into some wickedly unbalanced trade agreements - and to work off their enormous trade deficit to China. After many years, the Chinese decided to outlaw the British importation of opium as it's society was suffering, so the British declared war on China. The Brits won both conflicts, and this led to the fall of a Chinese Empire. Gotta love those Brits - just running around doing the world all sorts of favors........
