The year 1776 is significant in American history primarily because it marks the adoption of the Declaration of Independence, which was officially approved on July 4. This pivotal document, drafted mainly by Thomas Jefferson, proclaimed the thirteen American colonies’ separation from British rule and articulated the colonies’ desire for self-governance based on Enlightenment ideals of liberty, equality, and individual rights. The Declaration sparked the American Revolutionary War and laid the foundation for the United States as a nation committed to democratic principles. The Fourth of July is now celebrated annually as Independence Day, commemorating this historic event.
