The 13 colonies declared their independence in 1776 during the American Revolutionary War, with the Declaration of Independence. This document proclaimed the formation of a new independent nation. However, this was not recognized by Great Britain until the end of the war in 1783 and the subsequent Treaty of Paris.
The colonies first began to revolt against Great Britain in 1765 with the passing of the Stamp Act, a tax that was created to fund a British standing army in North America. The 13 colonies that gained their independence through the war are Delaware, Pennsylvania, New Jersey, Georgia, Connecticut, Massachusetts Bay, Maryland, South Carolina, New Hampshire, Virginia, New York, North Carolina and Rhode Island.
