The United States declared its independence in 1776, specifically on July 4th. The Declaration of Independence, primarily authored by Thomas Jefferson, announced the colonies' intention to break free from British rule, citing grievances against King George III. This decision was fueled by increasing dissatisfaction with British policies, taxation without representation, and restrictions on colonial governance. The Declaration symbolized the emergence of American national identity and laid the groundwork for a new nation based on principles of liberty and self-governance. The ideological foundation established in the Declaration continues to influence democratic ideals worldwide.
