The state is the central and most powerful institution in political science. It is a political organization that possesses ultimate authority (sovereignty) over a defined territory and its population.
Garner's Definition: "The state is a community of persons, more or less numerous, permanently occupying a definite portion of territory, independent (or nearly so) of external control, and possessing an organized government to which the great body of inhabitants render habitual obedience."
The state is composed of four essential elements. The absence of any one of them means there is no state.
These theories are speculative attempts to explain how the state first came into being.
This is the oldest theory. It holds that the state was created by God, and the ruler (King) is God's representative on Earth.
This theory argues that the state is not a natural or divine creation, but a deliberate human creation—an "artificial" institution made by a contract.
It posits a hypothetical "state of nature" (life before the state) from which people escaped by forming a contract.
| Thinker | Thomas Hobbes (Leviathan) | John Locke (Two Treatises of Government) | J.J. Rousseau (The Social Contract) | 
|---|---|---|---|
| State of Nature | "Solitary, poor, nasty, brutish, and short." A war of all against all. | Peaceful, but inconvenient. People had natural rights (Life, Liberty, Property) but no common judge. | A state of idyllic happiness and freedom. People were "Noble Savages". | 
| Reason for Contract | To escape fear and gain security. | To create an impartial judge to protect natural rights. | The rise of private property corrupted people and created inequality. | 
| Nature of Contract | People surrender all rights to a sovereign (Leviathan), who is not a party to the contract. | People surrender only the right to interpret and enforce the law of nature. A limited government. | People surrender their individual wills to a "General Will" (the common good). | 
| Result (Sovereignty) | Absolute, indivisible sovereignty. | Limited, constitutional sovereignty. People have the right to revolt. | Popular sovereignty. The people are the sovereign. | 
Criticism: It is unhistorical (there is no evidence of such a contract). The 'state of nature' is a fiction. However, its great value lies in promoting the ideas that the state is a human creation, based on the consent of the governed.
This is the most scientifically accepted theory. It argues that the state is not a product of a single event or contract, but the result of a slow, gradual process of evolution over a long period.
The state is a "growth, not a make". Several factors contributed to its development:
