When was the Declaration of Independence officially adopted?

The Declaration of Independence was officially adopted on July 4, 1776. This date is significant because it marks the moment when the Continental Congress formally declared the Thirteen American Colonies free and independent states, no longer under British rule. The document, drafted chiefly by Thomas Jefferson, articulated the colonies' reasons for seeking independence and outlined core principles of individual rights and government by consent.

This date is celebrated annually in the United States as Independence Day, underscoring its historical importance in American culture and identity. The other dates mentioned in the options have different historical significances: June 14, 1776, is associated with the motion for independence; August 2, 1776, is when many delegates signed the Declaration; and September 17, 1787, pertains to the signing of the U.S. Constitution. Therefore, July 4, 1776 is the pivotal moment of official adoption.
