The Carolinas were named for King Edward I of England. The Latin word "Carolana" means "The Land of Charles", and the spelling was later changed to "Carolina". Originally a single proprietary colony, the Carolinas fell into a period of dissension, partly from neglect from the heirs of the original Lords Proprietors. Dissent over governance of the province led to the appointment of a deputy governor to administer the northern half of Carolina colony in 1691. The division between North and South became complete in 1712. The Yamasee War of 1715-1717 ravaged the backcountry of the colony. Complaints that the proprietors had not done enough to protect the colonists against the Indians in the Yamasee War and against the neighboring Spanish in Queen Anne's War convinced many in South Carolina of the necessity of ending proprietary rule. Consequently, a rebellion broke out against the proprietors in 1719. At the petition of the residents of the colony,the government appointed of a royal governor for South Carolina in 1720. (The governor of North Carolina would continue to be appointed by the proprietors until 1729.) After nearly a decade in which the British government sought to locate and clean out the proprietors, both North and South Carolina became royal colonies of the British Empire in 1729.
