popular sovereignty

Popular sovereignty holds that ultimate political authority rests with the people, who are the original and continuing source of all legitimate governmental power. The doctrine was articulated by social-contract theorists — Thomas Hobbes located sovereignty in a power authorized by the people in Leviathan (1651), John Locke grounded government in consent in his Second Treatise (1689), and Jean-Jacques Rousseau gave the idea its fullest expression in Du contrat social (1762) through the concept of the "general will" (volonté générale). The principle found foundational constitutional voice in the Preamble to the United States Constitution (1787), which opens "We the People," and in Article 3 of the French Declaration of the Rights of Man and of the Citizen (1789): "The principle of all sovereignty resides essentially in the nation." It stands opposed to monarchical, divine-right, and parliamentary-supremacy conceptions of sovereignty.

Operationally, popular sovereignty is expressed through mechanisms that translate the will of the people into binding authority: written constitutions adopted by constituent assemblies, periodic free elections, universal adult suffrage, referenda and plebiscites, and the power to amend the fundamental law. In India, the Preamble's phrase "We, the People of India... do hereby adopt, enact and give to ourselves this Constitution" was held in Kesavananda Bharati (1973) to make the people the ultimate sovereign, while the basic-structure doctrine limits even the amending power under Article 368. The doctrine is closely linked to constitutionalism, since the people, having constituted government, also bind it by law. It is distinct from the parliamentary sovereignty of the British model (Dicey), where the Crown-in-Parliament is legally supreme.

Historically the term carried a specific and notorious meaning in antebellum United States politics, where it denoted the right of settlers in a federal territory to decide whether to permit slavery. Championed by Senators Lewis Cass and Stephen A. Douglas, it was embodied in the Compromise of 1850 and the Kansas–Nebraska Act of 1854, which repealed the Missouri Compromise line and triggered the violence of "Bleeding Kansas." The Dred Scott v. Sandford (1857) ruling that Congress could not bar slavery from territories undercut the doctrine. In its broader modern form, popular sovereignty underpins decolonization and the self-determination principle in Article 1(2) of the UN Charter (1945) and was invoked in referenda such as Brexit (2016) and Scotland's independence vote (2014).

For the exam, popular sovereignty is core to FSOT US Government and Society — expect questions distinguishing its abstract constitutional meaning from its antebellum territorial usage, and linking it to "We the People." In UPSC World History (GS Paper I) it appears within the Enlightenment, the American and French Revolutions, and Rousseau's general will. UPSC Polity tests it via the Preamble and Kesavananda Bharati. Typical question angles ask candidates to contrast popular sovereignty with parliamentary sovereignty, to identify Rousseau as its principal theorist, and to explain how the basic-structure doctrine reconciles popular sovereignty with constitutional limits.
