The U.S. Declaration of Independence is a historic document adopted on July 4, 1776, by the Second Continental Congress. It announced the thirteen American colonies' separation from British rule, outlining their grievances against King George III and asserting their right to self-govern. The Declaration emphasizes the principles of individual rights and government by consent, famously stating that "all men are created equal." It serves as a foundational text for American democracy and has inspired various movements for freedom and equality around the world.
