Planters embraced the use of slaves mainly because indentured labor became expensive. Some indentured servants were also leaving to start their own farms as land was widely available. Colonists tried to use Native Americans for labor, but they were susceptible to European diseases and died in large numbers. The plantation owners then turned to enslaved Africans for labor. In 1665, there were fewer than 500 Africans in Virginia but by 1750, 85 percent of the 235,000 slaves lived in the Southern colonies, Virginia included. Africans made up 40 percent of the South’s population.
