What fundamental principle is established in the Declaration of Independence regarding government?

The Declaration of Independence establishes the principle that government derives its authority from the consent of the governed. This foundational idea suggests that governmental power is not inherent or absolute; rather, it is granted by the people through their agreement and acceptance. The document emphasizes that a legitimate government must reflect the will and interests of the citizens it serves. Moreover, if a government fails to protect the rights of its people or acts against their interests, the Declaration asserts that the people have the right to alter or abolish it. This principle of consent is central to democratic ideals, indicating that a government's legitimacy relies on the active participation and approval of its citizens.
