What are European motives of imperialism?
Not only did the europeans think they were better than everyone else, but their motives were actually very simple. One was to aquire new territory to gain that territory's natural resources. The second was based off of the first...to get money. Those two reasons were the main motives for the entire history of European Imperialism. An example that depicts these two motives very well is "The Scramble for Africa." Also, England's exportation of opium to China is another good example.
Economic based motive was that Britain wanted to create new markets for products and to acquire our sacred raw materials. Britain wanted nothing more than to get their hands on Chinas delicate silk, porcelain, and tea in exchange for gold and silver.

Political based motive - Britain imperialized in order to make themselves seem more powerful to other countries and be superior to them.
