Which historical document declared the independence of the United States from Britain?

The Declaration of Independence is the historical document that announced the separation of the thirteen American colonies from British rule. Drafted primarily by Thomas Jefferson and adopted by the Continental Congress on July 4, 1776, it articulates the colonies' grievances against King George III and establishes the philosophical foundation for the new nation, asserting the principles of individual rights and self-governance. The document famously states that all men are created equal and endowed with unalienable rights, including life, liberty, and the pursuit of happiness.

In contrast, the Constitution serves as the framework for the United States government and was created later, in 1787. The Articles of Confederation were the first governing document of the United States, but they were ultimately deemed ineffective and replaced by the Constitution. The Bill of Rights, which comprises the first ten amendments to the Constitution, was ratified to protect individual liberties and was not concerned with declaring independence. Thus, the Declaration of Independence is distinctly recognized for its role in establishing the U.S. as an independent nation.
