Key Features of the State: Understanding Sovereignty and Authority

Every day, your life is shaped by an entity you rarely think about directly: the state. It collects your taxes, runs your schools, defends your borders, and decides what counts as a crime. But what actually makes a state a “state”? A cricket club has members and rules. A multinational corporation has resources and global reach. A family has authority and order. Yet none of these is a state. The difference lies in a specific set of features that political scientists use to define this unique form of political association. Drawing on the influential framework of political theorist Andrew Heywood, a state can be understood as a political association that establishes sovereign jurisdiction within defined territorial borders and exercises authority through permanent institutions. Let’s break down the five key features that give the state its distinct character.

Sovereignty: the supreme power 🔗

At the heart of any state lies sovereignty. This is the principle that the state holds absolute and unrestricted power within its territory. It stands above all other associations and groups in society. No corporation, religious body, or regional club can override the authority of the sovereign state. The word itself comes from the Latin superanus, meaning supreme or paramount, which captures exactly what it claims to be: the highest power.

The 17th-century philosopher Thomas Hobbes captured this idea vividly. He portrayed the state as a “Leviathan,” a gigantic monster whose overwhelming power was necessary to keep order and prevent society from collapsing into chaos. For Hobbes, only a supreme authority could guarantee peace among competing individuals.

Internal and external sovereignty 🔗

Sovereignty has two faces. Internal sovereignty refers to the state’s supreme authority within its own borders. Its will is final and binding for everyone living inside it, from individual citizens to the largest companies. External sovereignty means the state is independent and free from the control of any foreign power. As legal scholars explain, these two dimensions together establish internal supremacy and external independence as the defining capacity of a modern state.

This is why the question of sovereignty becomes so sensitive in matters of national territory and international agreements. When a country signs a treaty or joins a trade bloc, debates often erupt over whether it is “surrendering” its sovereignty. The concept also helps explain why political authority is so closely tied to clearly defined borders. State sovereignty divides global space into separate, distinct parcels of political authority, each ruled by its own supreme power.

Public institutions: making and enforcing decisions 🔗

A state cannot function on the idea of sovereignty alone. It needs machinery to actually make and carry out decisions. This is the role of public institutions, the second key feature of the state.

Heywood draws a sharp line between the “public” institutions of the state and the “private” institutions of civil society. Public bodies are responsible for making and enforcing collective decisions, while private bodies, such as families, businesses, and trade unions, exist to satisfy individual interests. Think about the contrast. A private company makes decisions to serve its shareholders and its own profit. The legislature, the courts, the police, and the bureaucracy make decisions that bind the entire society.

Why “public” matters 🔗

The public nature of these institutions has an important implication: they are funded by the public and are expected to act on behalf of the whole community, not any single individual or group. When a court passes a judgment or a legislature passes a law, the decision applies to everyone within the state’s jurisdiction. These institutions are also permanent. Governments come and go through elections, but the institutions of the state, such as the civil service, the judiciary, and the armed forces, continue regardless of which party is in power. This permanence gives the state its stability and continuity over time.

Legitimacy: ruling in the public interest 🔗

Why do people generally obey the laws of the state? It is not simply because they fear punishment. Most citizens follow the rules because they accept that the state has the right to make them. This acceptance is called legitimacy, and it is the third key feature of the state.

According to Heywood, the state is an exercise in legitimation. Its decisions are usually accepted as binding because they are claimed to be made in the public interest, or for the common good. The state is supposed to reflect the permanent interests of society as a whole, rather than the narrow interests of those who happen to hold power. This claim to be acting for everyone is what transforms raw power into rightful authority.

Power versus authority 🔗

The distinction between power and authority is crucial here. The sociologist Max Weber drew a sharp line between the two. Power is simply the ability to make someone act in a certain way, whether or not they agree. Authority is power that is accepted as legitimate by those who are subject to it. A robber with a gun has power over you, but no authority. A tax officer has authority because the system is recognised as legitimate.

This is why legitimacy is so important for stability. A government that has to rely purely on force, without any belief among its people that it has the right to rule, sits on shaky foundations. Legitimacy reduces the need for constant coercion, because citizens comply willingly. This is also where the state differs fundamentally from a criminal gang. A gang can extract money through threats, but it has no legitimate claim to do so, which is precisely why it remains criminal.

Authority backed by coercion: the instrument of domination 🔗

Legitimacy explains why people obey willingly. But what happens when they do not? This is where the fourth feature comes in. Heywood describes the state as an instrument of domination, meaning its authority is ultimately backed up by coercion. The state must have the capacity to ensure that its laws are obeyed and that those who break them are punished.

This combination of consent and coercion is what makes the state effective. Most of the time, the state rules through legitimacy and consent. But behind that consent always stands the possibility of force: the police, the courts, prisons, and ultimately the armed forces. The two work together. Consent makes the system run smoothly, while coercion ensures that even those who refuse to comply are still brought within the law.

Weber’s monopoly on legitimate violence 🔗

The clearest statement of this idea comes from Max Weber. In his 1919 lecture “Politics as a Vocation,” Weber defined the state by its monopoly on the legitimate use of physical force within a given territory. As Britannica explains this concept, the state alone has the right to use or authorise the use of physical force, and this is widely regarded as a defining characteristic of the modern state.

It is worth being precise about what “monopoly” means here. It does not mean that only the state ever uses force. Rather, the state is the only community that can legitimately authorise its use. A private security firm can employ guards, but only because the state permits it. Citizens may use force in genuine self-defence, but that right itself is derived from the state’s authority. The state can grant others the right to use force without losing its monopoly, as long as it remains the single source of that right. Weber identified this as central to how the modern state emerged: by displacing competing sources of authority, such as feudal lords and the Church, and centralising control over the means of coercion.

Territoriality: jurisdiction over a defined space 🔗

The fifth and final key feature is territoriality. A state is a territorial association. Its authority applies within clearly defined geographical borders, and its laws stop at those borders. This is what allows us to talk about distinct, separate states sitting side by side on a world map.

This feature is often traced to a specific historical moment. The Peace of Westphalia in 1648, which ended the Thirty Years’ War in Europe, is widely seen as formalising the modern principle of territorial sovereignty. It established the state as the principal actor in both domestic and international affairs, each ruling supreme within its own bounded territory. This is why the system of independent nation-states is sometimes called the “Westphalian” system.

How territory completes the picture 🔗

Territoriality is what ties the other four features together. Sovereignty is exercised within a territory. Public institutions operate within a territory. Legitimacy is claimed over the people within a territory. And the monopoly on legitimate force applies within a territory. Remove the territorial dimension, and the state loses its defining shape. Under international law, in fact, a recognised state is expected to have a defined territory, a permanent population, an effective government, and the capacity to enter into relations with other states, as outlined in the widely cited Montevideo Convention of 1933.

How these features distinguish the state from other associations 🔗

Put these five features together, and you can see why the state is unlike any other organisation in society. A trade union has members and makes decisions, but it has no sovereignty, no territory, and no legitimate monopoly on force. A religious organisation may command deep loyalty, but it cannot legally imprison those who disobey. A corporation may be richer and more globally connected than many governments, yet it operates within the legal framework set by states, not above it.

This last point is especially relevant in an age of powerful multinational corporations. These corporations can move capital across borders, influence economies, and shape consumer behaviour worldwide. Yet they remain subject to the sovereign authority of the states in which they operate. They cannot tax citizens, pass binding laws over the general population, or legitimately use force. The five features, namely sovereignty, public institutions, legitimacy, authority backed by coercion, and territoriality, mark out the state as a distinctive and supreme form of political organisation, even when other actors rival it in wealth or reach.

Understanding these features is the foundation for almost everything else in the study of politics. They explain how governments rule, why citizens obey, what gives laws their force, and how political authority is organised across the globe.

What do you think? If multinational corporations can sometimes wield more economic power than entire countries, does the traditional idea of sovereignty still hold up in today’s globalised world? And which of the five features do you think is the most essential for a state to survive: legitimacy, or its monopoly on force?
