The Declaration of Independence was the famous document adopted by the Continental Congress on July 4, 1776. Authored primarily by Thomas Jefferson, it formally declared the thirteen American colonies free from British rule. The document articulates the philosophical foundation for independence, emphasizing natural rights, such as life, liberty, and the pursuit of happiness. It asserts the principle that governments derive their power from the consent of the governed and articulates grievances against King George III to justify the separation. The Declaration has endured as a symbol of American ideals and democracy, inspiring movements for freedom worldwide.
