"Popular sovereignty" refers to the principle that government derives its authority from the people. This concept holds that governmental power is created and sustained by the consent of the governed, emphasizing that citizens have the right to participate in decision-making processes. In practice, it manifests through elections, referenda, and civic engagement. Popular sovereignty is a cornerstone of democratic systems, ensuring that the will of the majority is reflected in governance while respecting minority rights, which promotes legitimacy and accountability in political institutions.
