Before the arrival of Europeans, there was no Niger, Senegal, Ghana, Mali Nigeria, Tanzania, Kenya and or South Africa, these are all European creations, thus Africa as it exists today in the creation of the European white man when he craved up African territories into colonial territories for himself. These carved up nations often forced people who were peaceful and some who were hostile to each other into one all encompassing territories and to keep these peoples from uniting against him the European colonial white man often played up already existing ethnic rivalries and or created and instigated rivalries that previously didn't exist. This also ensured that even after the European white man's colonial rule ended he could still take control of the country's resources and exploit the people by playing up these same damn rivalries by supporting the African leader[often always corrupt] that is willing to sellout the most. Those who don't sellout are often labeled as evil, and anti-Western and anti-Democratic by the western world, all because the good African leaders refuse to allow the former colonial powers along with the US to exploit their country's resources.
