You're starting an interesting and important series in world history. In America, as you well say, in colonial times slave labour imported from Africa was used. In many of the Latin or Caribbean countries, such as Cuba, Haiti or Brazil, the plantation governs the central economy, so that the exploitation of the land, the cultivation of sugar cane, cocoa, cotton, was in the hands of slaves yorubas or mandingos. On the other hand, in my country, Venezuela, the black people from the Congo and Angola arrived, and as far as I know they were the most numerous in this area, because they were more culturally docile. Venezuela is a country that prides itself on being a mixture of Indians, blacks and Spaniards. A mixture that only gives us the color of the skin, the facial features, also the customs; so to speak of Africa is to speak of our ancestors. I am pending, @samminator
