The Nature of Sovereignty in Hobbes’ Political Philosophy

Thomas Hobbes wrote during one of the most turbulent periods in English history, the civil war of the 1640s, and his answer to political chaos was uncompromising: society needs a single, supreme authority whose power cannot be questioned, divided, or taken back. In his 1651 masterpiece Leviathan, this authority is the sovereign, and the concept of sovereignty itself is what holds the whole political community together. Understanding the precise nature of this sovereignty is essential for anyone studying classical political philosophy, because it sets the terms for almost every debate about state power that followed.

Sovereignty as the soul of the commonwealth 🔗

Hobbes describes the state as an “artificial person,” a constructed body made up of all its citizens. Within this metaphor, sovereignty plays a specific role. If the commonwealth is imagined as a body, then sovereignty is its soul, and the sovereign himself is the head. The point of this comparison is simple but powerful: just as a body without a soul is lifeless matter, a political community without sovereignty is nothing more than a disorganised collection of individuals. There is no unity, no common will, and no protection.

This is why Hobbes named his artificial person the “Leviathan,” after the biblical sea monster. The name signals overwhelming power, but the deeper idea is that the state only becomes a single coherent entity once sovereignty animates it. Citizens erect a common power at the head of their commonwealth, whether one person or an assembly, and agree to submit their wills to it in matters of common peace and safety. Without that act, the body of the state cannot move, decide, or defend itself.

Why a supreme power is necessary 🔗

To understand why Hobbes insisted on such concentrated power, you have to start with his account of the state of nature. This is the imagined condition of human life before any government exists. Hobbes argued that in this situation, with no laws, no police, and no courts, every person has a right to everything, which inevitably leads to conflict. He famously described life in this condition as “solitary, poor, nasty, brutish, and short.”

The only escape, in Hobbes’ view, is for people to transfer their natural rights to a single authority strong enough to keep everyone in check. The sovereign exists precisely to prevent a return to this violent disorder. This is the central justification for everything that follows: the sovereign’s enormous power is not an end in itself but the mechanism that guarantees survival and peace.

The four defining features of Hobbesian sovereignty 🔗

Hobbes’ sovereignty has four characteristics that together make it unlike most modern conceptions of political authority. As scholars summarise it, sovereign power for Hobbes is absolute, undivided, perpetual, and inalienable. Each of these deserves a close look.

Absolute 🔗

The sovereign’s authority is absolute, meaning it is not limited by any higher human law or institution. The sovereign is the sole author of the laws and also the highest judicial authority in the commonwealth. There is no appeal to a body above the sovereign, because by definition no such body exists. This absoluteness extends remarkably far in Hobbes’ system: the sovereign even determines what counts as legitimate knowledge and doctrine, since competing ideas about justice and religion were, in Hobbes’ experience, a major cause of civil war.

It is worth noting that “absolute” does not mean the sovereign can literally do anything. Hobbes reserved for subjects a narrow right of self-defence, the liberty to disobey when their own lives are directly threatened. This true liberty of subjects is one of the most debated features of his theory, because it sits uneasily alongside his defence of unlimited sovereign power.

Undivided 🔗

For Hobbes, sovereignty must be undivided. All the powers of the state, lawmaking, judging, taxation, command of the military, must be held by a single body. He believed that dividing these powers among competing institutions was a recipe for disaster. His evidence was direct and personal: the English Civil War, which he saw as the consequence of power being split between king and parliament. Divided power, in his view, invites factionalism, and factions eventually fight. A single, indivisible authority removes that danger.

Perpetual 🔗

Sovereignty is also perpetual. Once established, it continues indefinitely and does not expire or require regular renewal. This marks a sharp contrast with modern democratic systems, where leaders must periodically face elections and renew their mandate. Hobbes was suspicious of any arrangement that forced authority to be re-legitimised at intervals, because each transition created a window of uncertainty in which the commonwealth could slide back toward disorder.

Inalienable 🔗

Finally, sovereignty is inalienable. The sovereign cannot give away, sell, or transfer their ultimate authority to another. Even when the sovereign delegates particular tasks to ministers and officials, the underlying authority remains with the sovereign, who can reclaim it. The power is a single, unbroken whole that cannot be carved up or handed off without destroying the very thing that holds the commonwealth together.

The sovereign and the social contract 🔗

One of the most striking features of Hobbes’ theory is the relationship between the sovereign and the agreement that creates the state. People escape the state of nature by entering into a social contract, mutually covenanting with one another to surrender their rights to a common authority. Yet once that authority is established, the sovereign is not bound by the contract at all.

This is not a contradiction in Hobbes’ system but a deliberate feature of it. The contract is an agreement among the individuals, not between the individuals and the sovereign. As Britannica explains, the sovereign is not a party to the social contract and makes no promises in exchange for obedience. The sovereign receives that obedience as a free gift, given in the hope that they will provide protection. Because the sovereign never agreed to any terms, no terms can be used to constrain them, and the sovereign is not bound even by their own laws.

This design serves a clear purpose. If the sovereign could be removed for breaching the contract, then the power would not really be supreme; it would be conditional on the judgement of the subjects. And as the Yale political theorist Steven Smith notes in his lecture on Hobbes, the Hobbesian doctrine of sovereignty requires a complete monopoly of power within a territory. Any escape clause that let subjects judge and depose the sovereign would simply reopen the door to the conflicts that the commonwealth was created to end.

Two routes to sovereignty: institution and acquisition 🔗

Hobbes identified two ways a commonwealth, and therefore sovereignty, can come into being. Both are equally legitimate in his eyes, and importantly, both rest on the same underlying motivation.

Sovereignty by institution 🔗

Sovereignty by institution arises through agreement. When people mutually covenant with one another to obey a common authority, they have established sovereignty by institution. This is the classic picture of the social contract: a group of individuals, fearful of each other in the state of nature, voluntarily agree to set up a sovereign for their mutual protection. The driving force here is fear of one’s fellow human beings.

Sovereignty by acquisition 🔗

Sovereignty by acquisition arises through force. When people are threatened by a conqueror and submit, promising obedience in exchange for their lives, they establish sovereignty by acquisition. At first glance this looks like the opposite of a voluntary contract. But Hobbes insisted it carries all the same rights and obligations. A sovereign who takes power by force is as much a part of the social contract as one installed by agreement, because the conquered, by not resisting and choosing to obey, have effectively consented to the new authority in exchange for security.

Fear as the common foundation 🔗

What unites both routes is fear. In sovereignty by institution, people obey because they fear each other. In sovereignty by acquisition, they obey because they fear the conqueror. As the Stanford Encyclopedia puts it, these are equally legitimate ways of establishing sovereignty, and their underlying motivation is the same, namely fear. For Hobbes, fear is not a flaw in the system; it is the rational engine that makes peaceful cooperation possible. The threat of the sovereign’s power deters wrongdoing and creates the predictability that allows ordinary life to function.

Why this theory still matters 🔗

Hobbes’ vision of absolute, undivided, perpetual, and inalienable sovereignty has been challenged by almost every major thinker who came after him. John Locke argued that government should be limited and accountable, and that a rational person would never agree to be devoured by a lion to escape pole-cats and foxes. Modern constitutional democracies, with their separation of powers and regular elections, are in many ways a direct rejection of the Hobbesian model.

Yet the core insight endures. The idea that citizens consent to be governed in exchange for protection and the rule of law remains central to political thought. Hobbes forced political philosophy to confront a hard question: how much power must a state hold to guarantee order, and what are we willing to give up in return? Every debate about state authority, emergency powers, and the limits of obedience still echoes the problem he framed nearly four centuries ago.

What do you think? If Hobbes is right that divided power invites conflict, how do modern democracies manage to separate powers without collapsing into the chaos he feared? And is fear, rather than trust or shared values, really the most reliable foundation for political obedience?
