The significance of the Declaration of Independence in U.S. politics lies in its foundational role in asserting the nation’s principles of liberty and self-governance. Adopted on July 4, 1776, the document proclaimed the colonies' rights to independence from British rule, emphasizing ideals such as equality and the pursuit of happiness. It articulated the belief that governments derive their power from the consent of the governed and highlighted the right to revolt against oppressive rule. The Declaration continues to inspire democratic movements worldwide and serves as a symbol of American identity.
