As the sugar industry developed into its main commercial enterprise, Barbados was divided into large plantation estates that replaced the smallholdings of the early English settlers. In 1680, over half the arable land was held by 175 large enslavers/planters, each of whom enslaved at least 60 persons. The great enslavers/planters had connections with the English aristocracy and great influence on Parliament. (In 1668, the West Indian sugar crop sold for £180,000 after customs of £18,000. Chesapeake tobacco earned £50,000 after customs of £75,000). So much land was devoted to sugar that most foods had to be imported from New England. The poorer whites who were moved off the island went to the English Leeward Islands, or especially to Jamaica. In 1670, the Province of South Carolina was founded, when some of the surplus population again left Barbados. Other nations receiving large numbers of Barbadians included British Guiana and Panama.
