What document served as the foundation for American independence from British rule?

The Declaration of Independence served as the foundation for American independence from British rule because it was the formal statement adopted by the Continental Congress on July 4, 1776, announcing the colonies' separation from Great Britain. The document articulated the colonies’ grievances against King George III and outlined the philosophical justifications for independence, emphasizing the concepts of individual rights and the notion that government derives its power from the consent of the governed.

By declaring themselves independent, the American colonies asserted their right to self-governance and established a new nation based on Enlightenment ideals. This pivotal document not only marked a significant historical moment but also laid the groundwork for the development of democratic principles in the newly formed United States. Therefore, it is recognized as a crucial milestone that directly led to the establishment of American sovereignty.
