Answer: A main cause of the trade was the colonies that European countries were starting to develop. In America, for instance, which was a colony of England, there was a demand for many labourers for the sugar, tobacco and cotton plantations. As a direct result of the transatlantic slave trade, the greatest movement of Africans was to the Americas — with 96 per cent of the captives from the African coasts arriving on cramped slave ships at ports in South America and the Caribbean Islands.
Another difference between transatlantic and modern slavery is related to profitability and disposability. In the transatlantic slave trade, the focus of slave traders was on Africa and the high cost of transporting these people meant that once they were enslaved they were often maintained and reproduced.
