The Southern colonies were mainly dominated by the wealthy planters in Maryland, Virginia, and South Carolina. They owned increasingly large plantations that were worked by African slaves. Of the 650,000 inhabitants of the South in 1750, about 250,000 or 40 percent, were slaves. The plantations grew tobacco, indigo and rice for export, and raised most of their own food supplies. In addition, many small subsistence farms were family owned and operated by yeoman. Most white men owned some land, and therefore could vote.
