Which document declared America's independence from Britain?

The Declaration of Independence is the document that formally announced America's separation from British rule. It was adopted on July 4, 1776, and articulated the colonies' grievances against King George III, emphasizing their desire to be free from oppressive governance. This document not only laid the philosophical foundation for the new nation, asserting the principles of individual rights and self-governance but also signified a collective commitment by the thirteen colonies to establish themselves as a sovereign entity.

In contrast, the Articles of Confederation served as the first constitution for the United States, outlining the framework for government after independence was declared, while the Constitution established a stronger federal government later on. The Federalist Papers were a series of essays written to promote the ratification of the U.S. Constitution and do not pertain to the actual declaration of independence. Each of these documents plays an important role in American history, but only the Declaration of Independence was focused specifically on the act of declaring independence from Britain.
