Popular sovereignty or the sovereignty of the people's rule is the principle that the authority of a state and its government is created and sustained by the consent of its people, through their elected representatives (Rule by the People), who are the source of all political power. It is closely associated with social contract philosophers such as Thomas Hobbes, John Locke and Jean-Jacques Rousseau. Popular sovereignty expresses a concept and does not necessarily reflect or describe a political reality. It is usually contrasted with the concept of parliamentary sovereignty, and with individual sovereignty. The people have the final say in government decisions. Benjamin Franklin expressed the concept when he wrote, "In free governments, the rulers are the servants and the people their superiors and sovereigns".
