South Carolina, state in the southeastern United States, bordering the Atlantic Ocean. In
colonial days, the state was part of a vast region that Charles I, king of England, granted to Sir Robert Heath in 1629. The region was named Carolana, a word derived
from the Latin form of Charles, in reference to the monarch. His son, Charles II, changed the spelling of the region's name to Carolina in 1663. During the 17th century the area now covered by the present state came to be called South Carolina and the area to the north became North Carolina.
