The plantation system allowed owners to amass “large concentrations of laborers under the control of a single owner produced goods— sugar, tobacco, rice and cotton— for the free market.” The African slave trade was a major part of the world economy, and “slave labor played an indispensable part in its rapid growth.” In the case of the United States, this was paradoxical, as the country was founded and supposedly dedicated to the proposition that all men are created equal. Thus, by the 1820s, slavery became a source of conflict. Northern businesses prospered from slavery, and “New York merchants, working with their representatives in Southern ports and smaller towns purchased and shipped most of the cotton crop.” Economic gain prompted the growth in slavery, and slaves were essential for profit. As such, “[the] first mass consumer goods in international trade were produced by slaves— sugar, rice, coffee, and tobacco. The profits from slavery stimulated the rise of British ports such as Liverpool and Bristol, and the growth of banking, shipbuilding, and insurance, and helped to finance the early industrial revolution. The centrality of slavery to the British empire encouraged an ever- closer identification of freedom with whites and slavery with blacks.
