Why did the Declaration include the idea that all people have the right to change their government?

The Declaration includes the idea that all people have the right to change their government to affirm the principle of popular sovereignty, which holds that government derives its power from the consent of the governed. This notion was rooted in Enlightenment thinking, emphasizing individual rights and the belief that oppressive or unjust governments should be reformed or replaced. By asserting this right, the Declaration also served to justify the American colonies' rebellion against British rule, framing it as a legitimate response to tyranny. Ultimately, it underscored the commitment to liberty and democracy.
