Six of the colonies that eventually would form the nation were either founded or came under English rule during that period: New York, New Jersey, Pennsylvania (including Delaware), and North and South Carolina. All were proprietorships: that is, like Maryland they were granted in their entirety to one man or a group of men, who both held title to the soil and controlled the government. Charles II gave these vast American holdings as rewards to the men who had supported him during his years of exile. Mary Beth Norton et al.
