Answer:
Many countries in the world experienced imperialism when they were taken over and ruled by a more powerful country. The main motive for imperialism was to obtain and control a supply of raw materials for industries. This meant that a weaker country with abundant natural resources would be colonised. Imperialists were often brutal in the way they treated the indigenous population. Sometimes they chose a less aggressive approach, obtaining the co-operation of the local people and working with their traditional rulers and social and political structures and practices.
