There is a book entitled "The Negroes in Negroland" that should be a must read.
Published in 1868, it is a compilation of journals and first hand accounts by merchants, missionaries, explorers and slave traders describing their dealings with the native tribes of Africa.
Slavery, endless war, cannibalism, demon worship, etc. are all described in detail.
It explains a lot and is available at Amazon for now.
