What document did the colonies sign to declare independence from Britain?

The document that the colonies signed to declare independence from Britain is the Declaration of Independence. This pivotal document was adopted by the Second Continental Congress on July 4, 1776. It articulates the philosophical reasoning for independence, asserting the colonies' right to self-govern and providing a list of grievances against King George III to justify their break from British authority. The Declaration serves not only as a formal announcement of separation but also as a foundational text, outlining principles such as individual liberty and the idea that governments derive their power from the consent of the governed. Its significance lies in its role in inspiring future democratic movements and enshrining the values of freedom and equality.

The other documents mentioned, such as the Constitution and the Bill of Rights, were established later as part of the framework for the government of the newly formed United States, while the Articles of Confederation served as an initial governing document that followed independence.
