i might be wrong but im pretty sure majority of them are mezito (mixed w/ native indian roots) and there are alot of pockets in south america with large black populations like columbia and brazil with slave ancestry. Conquitsadors brought in african slaves that were bred with the natives.
Latin America is for the most part an oligarchy with the very wealthy elite being mostly white european decent. They live like kings while the urban natives live on less than $40 dollars a week in most cases.
I think the difference is that #1 the americas were a new discovery/world where as Africa had already established itself with civilizations like Egypt who were a huge superpower in the ancient world. #2 Gold was as common as sand, the amount of gold found in inca/mayan cities sounded like a dream when news came over the ocean So it attracted the worst kind of people ready to sail across the ocean and get theirs
well there are definitely a lot of "mestizos" but personally i feel mestizo is a european construct and thats why i would rather separate latin america history from african history, im not indigenous but i would also seperate indigenous history from latin america history, "mestizos" do not represent an indigenous culture they actually represent a eurocentric culture, for the most part the so called mestizo carries on the racism and social ideas of their european ancestors
there are some pockets of africans and indigenous people, but if you take away the one drop rule latin america = european
the GGS book breaks it down very well how europeans tried to colonize africa but failed becuase in terms of disease the impact was opposite of what happened in the americas, the europeans were dropping like flies from disease, their crops wouldnt grow and the africans resisted to much for actual colonization
it wasnt really about gold, north america for example had no gold and they displaced the natives anyway, europeans where trying to do the same thing in africa, they conquered africa with guns and by using the existing tribal structures, but they were never able to actually displace the native population like they did in the americas
guns germs and steel has some controversial theories but in terms of history its excellent, it breaks it down very well the difference in the history of europeans in africa vs the americas
