The famous document that granted independence to the United States is the Declaration of Independence, adopted on July 4, 1776. Drafted primarily by Thomas Jefferson, this landmark document articulated the colonies' grievances against King George III and asserted their right to self-governance. It emphasized fundamental principles, such as equality, the inalienable rights of life, liberty, and the pursuit of happiness. The Declaration served not only as a formal statement of independence from British rule but also as an inspiration for democratic movements around the world, symbolizing a break from tyranny and the establishment of a nation based on Enlightenment ideals.
