When was the Declaration of Independence adopted?

The Declaration of Independence was adopted on July 4, 1776, marking a pivotal moment in American history. This date signifies the formal assertion of the thirteen colonies' desire to separate from British rule and establish themselves as an independent nation. The Declaration, primarily authored by Thomas Jefferson, articulated the colonies' grievances against King George III and laid out the philosophical foundation for independence, emphasizing principles such as individual rights and the notion that governments derive their power from the consent of the governed. This date is celebrated annually in the United States as Independence Day, reflecting its significance in the context of national identity and democracy.

The other dates provided in the choices are associated with different historical milestones. September 17, 1787, is known for the signing of the U.S. Constitution; March 3, 1781, marks the adoption of the Articles of Confederation, which served as the first governing document of the United States; and April 12, 1775, is part of the early timeline of the Revolutionary War, specifically related to the Battles of Lexington and Concord. None of these events relate to the adoption of the Declaration of Independence, reinforcing the correctness of July 4, 1776, as the significant date in question.
