- The opium war was between Britain and China
Long term causes
Cultural and Diplomatic Differences
- Chinese believed that they were the at the center of the world
- They were surrounded by obedient, “Inferior” nations
- However, by the early 19th century Britain too believed themselves to be number 1 power in the world. The most civilized and cultured nations
- So basically both of the countries viewed each other as inferior

Economic Differences/Attitude towards Trade
- British were frustrated with China's “Closed door” trading system
- This was known as the caton system
- The British wanted china to have an open door aka free trade policy
- Wherein merchants and businessman could trade freely in China
- The British organised two diplomatic missions with china with the aim of improving trade relations between the two countries


Short Term Causes
- Dispute over the opium trade
- The british wanted to stop paying china in gold and silver
- They wanted to find smth that they could trade that would interest china
- They came up with the idea of trading opium to china
- Opium had been used in china for a long time
- Medicinally alleviates pain
- But the british introduced the drug as a recreational habit
- being highly addictive, smoking opium took a hold over china
- The key motive of the britishers was that the demand for chinese tea had grown back at home, which offered vast profits to companies
- The main company trading with the chinese was the british east india company
- The east india company grew opium in india
- The east india company exchanged vast amounts of with china, and the social and economic impacts of the drug were seen pretty soon
- Opium addiction in china:
- Affected the authorities
- Destroyed families
- Poor families even sold their own children to buy opium
- Instead of silver flowing into china, it started flowing out of their hands and into the british opium traders
- The demand for opium far outweighed the demand for tea
- It became far more profitable than selling tea and silk to the home markets
