The Atlantic slave trade or transatlantic slave trade took place across the Atlantic Ocean from the 16th through to the 19th centuries. The vast majority of slaves transported to the New World were Africans from the central and western parts of the continent, sold by Africans to European slave traders who then transported them to North and South America. The numbers were so great that Africans who came by way of the slave trade became the most numerous Old-World immigrants in both North and South America before the late eighteenth century. The South Atlantic economic system centered on making goods and clothing to sell in Europe and increasing the numbers of African slaves brought to the New World. This was crucial to those European countries which, in the late seventeenth and eighteenth centuries, were vying with each other to create overseas empires
