De Brahm immigrated to the colonies from Germany in 1751 and became a surveyor in Georgia in 1754. He created this map of South Carolina and Georgia in 1757 using scientific topographical surveys. The economy of this region thrived on rice, indigo, and cotton and depended on the labor of slaves. New England slave owners tended to own a few slaves, but Southern plantations depended on a larger enslaved labor force. The cartouche in the bottom right features a scene of slaves at work. After the French and Indian War, De Brahm supervised the British coastal survey for the southern district.
