European Imperialism in Africa was termed as the "<em>Scramble for Africa."</em> This was a time when majority of the countries in Africa were colonized by the Europeans. Much of their land was controlled because of having rich natural resources. The colonizers also imposed<u><em> economic policies that were unfair to the Africans.</em></u> Families were separated because of "forced labor." Men were obligated to work on the<em> mining areas and farms.</em> This left the women and children devastated. Since Europeans did not respect the traditions of the Africans, it led to the breaking up of values in the society.
