Etymology and National Identity

Origin of the Name

The name "United States of America" emerged during the American Revolution. In 1775, the Second Continental Congress referred to the colonies as "United Colonies" in early documents. The Declaration of Independence (July 4, 1776) used "the thirteen united States of America." On September 9, 1776, Congress officially adopted "United States of America" to replace "United Colonies." The Articles of Confederation (ratified 1781) formalized it in Article I, and the 1787 Constitution retained the name, emphasizing the union of states.
