I dont know how it happened.. but it did.. they were ruled by bad landlords and it was left really fucked up
I know it happened. Long before the white man arrived though, did Africa have any substantial government structure, defense force or civilization to speak of?

I know that outside invaders of Europe, Asia, and the Middle East were frequently repelled by the native populations prior to the 13th century even. One nation would invade the other, war would ensue, back and forth over and over.
Why were Europeans allowed to move into Africa, generally without any resistance (maybe even welcomed by Africans that sold other Africans to the invaders)?

I mean no disrespect here.
