Popular Sovereignty: What It Is, How It Is Exercised, and Its Limits

Popular sovereignty locates the legitimate source of political power in the people. Understanding it requires distinguishing who is sovereign, how that sovereignty is exercised, and which limits protect everyone’s freedom.

Popular sovereignty is the principle that legitimate political authority comes from the people. Rulers, legislators, and other public officials do not possess power by their own right: they exercise it because a political order recognized by citizens assigns them powers and responsibilities.

This definition answers who ultimately holds political power, but it does not by itself determine how a country should be governed. The people do not always assemble together or speak with one voice. Constitutions therefore establish procedures—elections, representation, referendums, and decision rules—to turn a plurality of views into public decisions.

Key idea: Sovereignty belongs to the people; state institutions exercise only the powers that the constitutional order grants them.

Holding sovereignty does not mean exercising it at all times

It helps to separate two questions. The first is who legitimates political power: under popular sovereignty, the answer is the people. The second is who makes each decision and through what procedure: that answer depends on each country’s institutions.

Article 21 of the Universal Declaration of Human Rights reflects this distinction. It recognizes everyone’s right to take part in the government of their country, directly or through freely chosen representatives. It also states that the will of the people is the basis of public authority and must be expressed through genuine, periodic elections with universal and equal suffrage.

Popular sovereignty is therefore not the same as continuous voting. In a representative democracy, citizens elect people to perform particular functions for a limited period. Those representatives make public decisions, but they do not replace the people as the source of legitimacy or receive a blank check. Their authority remains delegated and subject to rules.

The people, the electorate, and a majority are not the same thing

In everyday language, these terms are often conflated. Yet they refer to different realities:

• The people are the political community to which sovereignty is attributed.
• The electorate consists of the people entitled to vote under the rules in force.
• A majority is the outcome of a particular decision among those who took part.

An electoral majority may authorize a government or approve a proposal, but it does not embody a socially homogeneous will. Citizens who chose other options, abstained, or could not vote remain part of the political community. This matters because it prevents a temporary victory from becoming a claim to speak for every person.

The problem already appears in Jean-Jacques Rousseau, a decisive influence on the modern formulation of popular sovereignty. In The Social Contract, he distinguished the general will, directed toward the common good, from the “will of all,” understood as the sum of private interests. His argument does not allow the general will simply to be equated with any majority opinion. Nor does it, by itself, describe how contemporary constitutional democracies operate.

Popular sovereignty and national sovereignty

Constitutional theory often distinguishes popular sovereignty from national sovereignty. The former attributes sovereignty to the concrete people and has historically been associated with more direct participation. The latter attributes it to the nation as a collective and abstract entity, and is often linked to representation: representatives act in the name of the whole, not merely as spokespeople for each voter.

The distinction is useful for understanding doctrinal traditions, but actual systems combine elements of both. Spain’s Constitution, for example, uses the expression “national sovereignty” while also declaring that it resides in the Spanish people. The French Constitution, in turn, provides that national sovereignty belongs to the people, who exercise it through their representatives and by referendum.

These examples do not establish a universal formula. They show that constitutional texts can combine different vocabularies and mechanisms. What matters is to examine whom they identify as the source of legitimacy, which avenues for participation they recognize, and how they hold those who exercise power to account.

Key idea: Popular sovereignty explains where authority comes from. Representation, suffrage, and referendums are among the ways it may be exercised.

Direct democracy and representative democracy

Popular sovereignty can be expressed through direct or representative channels. Direct channels include referendums and other consultations in which citizens decide a question themselves. Representative channels include elections for legislators and executive authorities. Both can coexist within the same system.

No mechanism by itself removes the difficulties of collective decision-making. A direct consultation requires clear questions, adequate information, and guarantees of free competition. Representation permits deliberation, negotiation, and accountability, but it can distance officeholders from citizens. Institutions must address those risks without confusing participation with the mere holding of votes.

Political rights—the right to vote, stand for office, associate, speak freely, and participate—make popular sovereignty more than a declaration. If the opposition cannot organize, the press cannot inform, or the outcome is predetermined, an election may retain its form while losing its legitimating function.

Can a majority do anything it wants?

The fact that power comes from the people does not mean that every majority decision is just or legally valid. Here it is necessary to distinguish legitimacy of origin from the legitimate exercise of power. Winning an election authorizes a government to govern within certain powers; it does not authorize it arbitrarily to abolish freedoms, disregard procedures, or persecute dissenters.

A constitutional state governed by the rule of law also subjects majorities to public rules. Legality, separation of functions, independent judges, and mechanisms of accountability reduce the risk of abuse. The Venice Commission’s Rule of Law Checklist identifies, among other elements, legal certainty, prevention of abuse of power, equality before the law, and access to justice.

Individual rights serve an equally democratic function. They protect minorities, dissenters, and unpopular people, but they also preserve the conditions under which the people can revise their own decisions. Freedom of expression permits criticism of government; freedom of association makes it possible to build alternatives; future elections allow citizens to replace those in office. Without such guarantees, today’s majority could prevent a different majority from existing tomorrow.

Key idea: Constitutional limits do not displace popular sovereignty. They prevent representatives or a temporary majority from turning a limited authorization into absolute power.

This does not settle every debate. A political community may amend its constitution through the procedures it provides, and the question of constituent power raises deeper problems about the origin and transformation of a legal order. But in ordinary government, invoking “the will of the people” does not relieve any authority of the duty to respect powers, rights, and checks.

A source of legitimacy, not an unlimited license

Popular sovereignty displaced the idea that political rule naturally belongs to a monarch, dynasty, or elite. Its promise is self-government: people subject to laws should be able to participate, directly or indirectly, in shaping the power that makes them.

That promise is fulfilled when citizens can express their will under free conditions, when legitimate institutions can turn it into decisions, and when those decisions can be corrected over time. The people are the source of authority, but no momentary majority exhausts the whole people. Participation and limits are therefore not rival principles: together, they make power democratic, accountable, and compatible with each person’s freedom.
