Slavery in America began when the first African slaves were brought to the North American colony of Jamestown, Virginia, in 1619, to aid in the production of such lucrative crops as tobacco. Slavery was practiced throughout the American colonies in the 17th and 18th centuries, and African-American slaves helped build the economic foundations of the new nation. The invention of the cotton gin in 1793 solidified the central importance of slavery to the South’s economy.
