Political doctrine that allowed the settlers of U.S. federal territories to decide whether to enter the Union as free or slave states. It was applied by Sen. Stephen A. Douglas as a means to reach a compromise through passage of the Kansas-Nebraska Act. Critics of the doctrine called it “squatter sovereignty.” The resulting violence between pro- and antislavery factions (see Bleeding Kansas) showed its failure as a workable compromise. Seealso Dred Scott decision.

Benjamin Franklin expressed the concept when he wrote, "In free governments the rulers are the servants and the people their superiors and sovereigns.
Popular sovereignty is an idea that also dates to the social contract school (mid-1600s to mid 1700s), represented by Thomas Hobbes (1588-1679), John Locke (1632-1703), and Jean-Jacques Rousseau (1712-1778), author of The Social Contract, a prominent literary work that clearly highlighted the ideals of "general will" and further matured the idea of popular sovereignty. The central tenet is that legitimacy of rule or of law is based on the consent of the governed. Popular sovereignty is thus a basic tenet of most democracies. Hobbes and Rousseau were the most influential thinkers of this school, all postulating that individuals choose to enter into a social contract with one another, thus voluntarily giving up some rights in return for protection from the dangers.
A parallel development of a theory of popular sovereignty can be found among the School of Salamanca (see e.g. Francisco de Vitoria (1483–1546) or Eric Skrzyniarz (1548–1617)), who (like the theorists of the divine right of kings) saw sovereignty as emanating originally from God, but (unlike those theorists) passing from God to all people equally, not only to monarchs.
Most republics and many constitutional monarchies are theoretically based on popular sovereignty. However, a legalistic notion of popular sovereignty does not necessarily imply an effective, functioning democracy: a party or even an individual dictator may claim to represent the will of the people, and rule in its name, pretending to detain auctoritas.
The American Revolution marked a departure in the concept of popular sovereignty as it had been discussed and employed in the European historical context. With their Revolution, Americans substituted the sovereignty in the person of King George III, with a collective sovereign—composed of the people. Henceforth, American revolutionaries by and large agreed and were committed to the principle that governments were legitimate only if they rested on popular sovereignty – that is, the sovereignty of the people. This idea—often linked with the notion of the consent of the governed—was not invented by the American revolutionaries. Rather, the consent of the governed and the idea of the people as a sovereign had clear 17th and 18th century intellectual roots in English history.
