The correct answer to this open question is the following.
Although you did not include the "name" given by the Europeans to the African people, we could say that European were despotic and arrogant in considering Africans ignorant and primitive, despite Africans had their culture, traditions, and customs.
Let's remember that we do not have the right to judge people when we do not know their past, culture, and their motives. And that is what the Europeans did, they judged.
European superpowers such as Britain, France or Portugal, were just interested in exploiting natural resources and raw materials such as gold, diamonds, ivory, and timber, that abound in some regions of the African continent.
