The Declaration of Independence of The United States of America The Declaration of Independence is the usual name of a statement adopted by the Continental Congress on July 4, 1776, which announced that the thirteen American colonies, then at war with Great Britain, regarded themselves as 13 newly independent sovereign states, and no longer a part of the British Empire. Instead they formed a new nation—the United States of America. John Adams was a leader in pushing for independence, which was unanimously approved on July 2. A committee had already drafted the formal declaration, to be ready when Congress voted on independence. The term "Declaration of Independence" is not used in the document itself.
