How does the declaration reflects popular sovereignty?

The Declaration of Independence reflects popular sovereignty by asserting that government derives its power from the consent of the governed. It emphasizes that individuals have the right to alter or abolish a government that fails to protect their unalienable rights, thereby placing ultimate authority in the hands of the people. This principle underscores the belief that legitimacy comes from the will of the populace, reinforcing the idea that citizens are the true source of political power.
