When was the Declaration of Independence adopted?

The Declaration of Independence was adopted on July 4, 1776, a date that is now celebrated annually in the United States as Independence Day. This momentous event marked the formal separation of the thirteen American colonies from British rule, as well as the assertion of their right to self-governance. The document, drafted primarily by Thomas Jefferson, articulated the colonies' grievances against King George III and expressed the fundamental principles of individual liberty and government by consent of the governed.

The other dates provided represent significant events in American history but are not related to the adoption of the Declaration of Independence. September 17, 1787, marks the signing of the United States Constitution, which established the framework of the federal government. March 4, 1789, is recognized as the date when the first Congress met under the Constitution, leading to the formal operation of the national government. June 2, 1776, does not correspond to a significant event recognized in the same way as July 4, 1776, further emphasizing that the correct date for the adoption of the Declaration of Independence is indeed July 4, 1776.
