What were the 3 effects of European imperialism on Africa

1. Shortage of natural resources

2. Deaths of Africans from foreign diseases brought by Europeans

3. Artificial borders drawn up by the Europeans often forced rivalling tribes and peoples together in one place, inciting violence and war. In addition, some tried to rebel against European imperialists.
