The document that humbled Kings and changed the course of the world was the Declaration of Independence - which established the revolutionary, fundamental principle that governments existed only by virtue of the "consent of the governed" who had the Right to withdraw said consent at their discretion..
Everything else is details.
As thankful as I am to be an American, I have never given my consent to be governed, let alone been asked.
> [the governed have] the Right to withdraw said consent at their discretion..
So wrote Jefferson, but this Right is not in the Constitution.
Granted that we must be governed, we may at least take consolation in the fact that we are all equal under the law...aren't we?
