Answer: Three effects that European imperialism had on Africa included a more structured political system with an organized government, the development of industrial technology and the idea of nationalism, which led to wars and revolutions later on.Europeans changed the economy from a model of producing foods for need to mainly the production of cash crops. All crops produced by Africans were exported and prices were set by the colonies. Africans were not allowed to grow these cash crops to benefit themselves.Imperialism adversely affected the colonies. Under foreign rule, native culture and industry were destroyed. Imported goods wiped out local craft industries. By using colonies as sources of raw materials and markets for manufactured goods, colonial powers held back the colonies from developing industries.
