"One can say that Europe allocated to Africa the role of supplier of human captives to be used as slaves in various parts of the world. When Europeans reached the Americas, they recognized its enormous potential in gold and silver and tropical produce. But that potential could not be made a reality without adequate labor supplies. The indigenous Indian population could not withstand new European diseases such as smallpox, nor could they bear the organized toil of slave plantations and slave mines, having barely emerged from the hunting stage. That is why in islands like Cuba and , the local Indian population was virtually wiped out by the white invaders. At the same time, Europe itself had a very small population and could not afford to release the labor required to tap the wealth of the Americas. Therefore, they turned to the nearest continent, Africa, which incidentally had a population accustomed to settled agriculture and disciplined labor in many spheres. Those were the objective conditions lying behind the start of the European slave trade, and those are the reasons why the capitalist class in Europe used their control of international trade to insure that Africa specialized in exporting captives."
