The document outlines the 13 original colonies of British North America, dividing them into three regional groups: the New England colonies, the Middle colonies, and the Southern colonies. The New England colonies were initially settled by Puritans in the early 1600s and included Massachusetts, Plymouth, New Hampshire, and Rhode Island. The Middle colonies spanning the mid-Atlantic were settled slightly later and were home to diverse Dutch, English, and other ethnic groups. The Southern colonies stretching along the Atlantic coast were initially focused on agriculture and included the colonies of Virginia, Maryland, the Carolinas, and Georgia, with some settlement also occurring from other European powers like England, Spain, and France in the region.
