What does the Declaration of Independence signify?

The Declaration of Independence signifies the colonies' separation from British rule because it formally announces that the American colonies regard themselves as independent states, free from the authority of the British Crown. This document, adopted on July 4, 1776, articulates the philosophical and political reasons for the colonies' decision to break away, asserting the principles of individual rights and governance by consent of the governed. It sets forth the belief that all men are created equal and endowed with unalienable rights, including life, liberty, and the pursuit of happiness, and it posits that governments derive their just powers from the consent of the governed.

While it does have implications related to war, such as justifying the colonies' pursuit of independence and potential conflict with Great Britain, its primary significance lies in its declaration of independence rather than in declaring war or establishing a government. Moreover, it does not outline the U.S. Constitution, which was drafted later, nor does it represent the establishment of the first American government, as that occurred prior to the Declaration.
