Declaration of Independence

The United States Declaration of Independence is a statement adopted by the Continental Congress on July 4, 1776, announcing that the thirteen American colonies then at war with Great Britain were no longer a part of the British Empire. Written primarily by Thomas Jefferson, the Declaration is a formal explanation of why Congress had voted on July 2 to declare independence from Great Britain, more than a year after the outbreak of the American Revolutionary War. The birthday of the United States of America-Independence Day-is celebrated on July 4, the day the wording of the Declaration was approved by Congress.
