Why was imperialism done in africa?

In the late 18th century, life in Europe and America changed dramatically. Revolutions in America and France ushered in a new political order. The Industrial Revolution in Britain modernised farming, the processing of raw materials and manufacturing of goods. Later industrialisation spread to Europe and to the USA. Economic progress came at the cost of rapid urbanisation and social problems. Industrialisation also influenced political change. Britain developed into a democracy as a result. Industrialisation created a huge demand for raw materials and led to the colonisation of Africa and Asia for these resources. Industrialisation and technological progress boosted European and American confidence, and national pride. They became convinced that they were superior. Their lust for power climaxed in the two World Wars of the 20th century.
