The United States Declaration of Independence announced that the thirteen American colonies then at war with Great Britain became independent and thus 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, over a year after the outbreak of the American Revolutionary War. The US Independence Day is celebrated on July 4, the day the wording of the Declaration was approved by Congress.
