The Thirteen Colonies were a group of British colonial settlements on the eastern seaboard of North America that, between 1607 and 1733, were established under royal charters, proprietary grants, or corporate agreements. They are conventionally listed as Connecticut, Delaware, Georgia, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, and Virginia. In 1776, delegates from these colonies formally declared independence from Great Britain, and the colonies became the original constituent states of the United States of America.
By the mid-eighteenth century, the colonies had developed distinct economic systems - plantation agriculture dependent on enslaved labor in the south, mixed farming and trade in the middle colonies, and maritime commerce and small-scale farming in New England - alongside locally elected assemblies that exercised considerable practical self-governance. Tensions with the British Parliament over taxation, trade regulation, and imperial authority escalated through the 1760s and 1770s, culminating in open armed conflict in April 1775 and the Declaration of Independence on 4 July 1776. The political, economic, and ideological causes of that rupture remain subjects of ongoing historical interpretation. For an extended treatment, see Thirteen Colonies - History.
Historians broadly agree on the sequence of major events, key dates, and the institutional structures of colonial governance. Interpretive questions - such as the relative weight of economic grievances versus constitutional principle, the role of slavery in shaping colonial political culture, and how representative colonial political institutions actually were - remain active areas of scholarly debate. See Thirteen Colonies - Historiography Consensus.
Several interpretive frameworks have shaped how historians and commentators understand the Thirteen Colonies and their path to independence:
