What document announced America's independence from Great Britain?

The document that announced America's independence from Great Britain is the Declaration of Independence. This historic text was adopted by the Second Continental Congress on July 4, 1776, and it formally declared that the thirteen American colonies were no longer under British rule and had become independent states. The Declaration outlines the philosophical foundations of American democracy, asserting the right to self-governance and the belief that governments derive their power from the consent of the governed.

The other options do not serve this purpose. The Constitution serves as the foundational legal document for the United States government, establishing the framework for the national government and outlining the laws and principles by which the country is governed. The Bill of Rights, which comprises the first ten amendments to the Constitution, enumerates specific rights and protections for individuals but does not address independence. The Federalist Papers are a collection of essays written to support the ratification of the Constitution and discuss its principles but also do not have a direct connection to declaring independence. Thus, the Declaration of Independence is the key document that clearly articulates the colonies' intention to separate from British authority.
