In what year was the Declaration of Independence adopted?

The Declaration of Independence was adopted in 1776, which marks a pivotal moment in American history as it signifies the formal assertion of independence from British rule. This document, primarily authored by Thomas Jefferson, articulated the colonies' reasons for seeking autonomy and outlined the philosophical underpinnings of that quest, particularly the rights to life, liberty, and the pursuit of happiness.

The adoption took place on July 4, 1776, during the Second Continental Congress, and this date is celebrated annually in the United States as Independence Day. This event was significant because it not only marked the separation of the thirteen American colonies from Great Britain but also laid the foundation for the establishment of a new nation grounded in democratic ideals and individual freedoms.

The other years listed do not pertain to the adoption of the Declaration. For example, 1775 is notable for the outset of armed conflict with the battles of Lexington and Concord, whereas 1787 is marked by the Constitutional Convention that resulted in the drafting of the U.S. Constitution, and 1789 is significant as the year the new Constitution went into effect and George Washington was inaugurated as the first President of the United States.
