HISTORICAL FOUNDATIONS OF THE INTERNATIONAL POLITICAL SYSTEM

As political practice evolved, so too did the theory of sovereignty. Thinkers from the sixteenth to the eighteenth centuries articulated the intellectual foundations of the sovereign state, defining its nature, limits, and legitimacy.

Jean Bodin and the Concept of Absolute Sovereignty

The French jurist Jean Bodin (1530–1596) was among the first to define sovereignty in systematic terms. Writing in the aftermath of the French Wars of Religion, Bodin’s Six Books of the Commonwealth (1576) argued that political stability required a single, undivided source of authority.

He defined sovereignty as the “absolute and perpetual power of a commonwealth”, residing in the sovereign ruler. For Bodin, sovereignty was indivisible and not subject to any higher law, except divine and natural law. His ideas justified the strengthening of monarchic power in the face of religious fragmentation and feudal resistance.

Bodin’s conception reflected the realities of his time: the need for centralized authority to restore order. Yet his theory also laid the foundation for the modern notion of legal sovereignty, in which the state possesses ultimate lawmaking power within its territory.

Thomas Hobbes and the Sovereign State

The English philosopher Thomas Hobbes (1588–1679) further developed the concept in Leviathan (1651). Writing during the English Civil War, Hobbes viewed sovereignty as the solution to the chaos of anarchy. In the absence of a strong authority, he argued, human life would be “solitary, poor, nasty, brutish, and short.”

To escape this condition, individuals entered into a social contract, transferring their natural freedom to a sovereign power—an artificial “Leviathan”—that would ensure peace and order. For Hobbes, sovereignty was absolute, indivisible, and necessary for civil society.

His ideas gave sovereignty a rational and secular justification, replacing divine right with political necessity. Hobbes’s model established the theoretical basis for the modern state as an autonomous entity, deriving legitimacy from the consent of its people rather than from God or empire.

Later Developments: Locke, Rousseau, and the People’s Sovereignty

While Bodin and Hobbes emphasized monarchical sovereignty, later thinkers redefined sovereignty in popular terms. John Locke (1632–1704) argued that sovereignty ultimately resided in the people, who retained the right to resist tyrannical rule. Jean-Jacques Rousseau (1712–1778) expanded this idea, asserting in The Social Contract (1762) that the “general will” of the people constituted the true sovereign.

These Enlightenment ideas shifted the basis of sovereignty from rulers to citizens, paving the way for constitutional government and national self-determination. Thus, sovereignty evolved from the authority of kings to the authority of peoples—a transformation that would shape modern democracy and the postcolonial world.
