When was the Declaration of Independence adopted?

The Declaration of Independence was formally adopted on July 4, 1776. This date is significant as it marks the day when the thirteen American colonies declared their independence from British rule, a pivotal moment in history that led to the formation of the United States. The adoption of the document was a culmination of growing discontent against British governance and a desire for self-determination.

This date has since been celebrated annually as Independence Day in the United States, commemorating the principles of freedom and democracy outlined in the Declaration. The other dates listed do not hold any historical significance with regard to the adoption of this foundational document, which is why they do not represent the correct answer.
