What document did the American colonies adopt in 1776 to declare their independence?

The American colonies adopted the American Declaration of Independence in 1776 to formally declare their independence from British rule. This document articulated the colonies' grievances against King George III and expressed their philosophical justification for seeking independence. It emphasized the Enlightenment principles of individual rights and the belief that governments exist to serve the people, with the consent of the governed being central to its argument.

The Declaration provided a foundational statement about human rights and the role of government that would influence future democratic movements not only in America but around the world. It was signed on July 4, 1776, and is celebrated as a critical milestone in American history, marking the establishment of the United States as an independent nation.
