State — Definition, Essential Elements and Kinds

In 1933, at Montevideo, the American States sat down to answer a question that sounds obvious but is not: when is a “State” a State? The result — the Montevideo Convention of 1933 — set out four plain tests. They are still the answer today. When a would-be country like “Somaliland” or the “Vatican” is argued over, lawyers reach for the same four boxes to tick.

What makes an entity a State — the four Montevideo criteria

A State is the basic unit and primary subject of international law: a community occupying a defined territory, under an organised government, independent of external control and able to deal with other States. The classic test is Article 1 of the Montevideo Convention on the Rights and Duties of States (1933), which lays down four essential elements. Learn each — the examiner wants them explained, not just listed.

1. A permanent population — a stable community of people living there. The number does not matter (micro-States have tiny populations); what matters is that they are settled, not nomadic passers-by.
2. A defined territory — a piece of the earth’s surface over which the State exercises authority. The borders need not be fully settled or undisputed (India and Israel had disputed borders and were still States); there must simply be an identifiable territory.
3. A government — an organised authority that actually exercises control over the population and territory. It must be effective, but its form (monarchy, republic) is irrelevant.
4. Capacity to enter into relations with other States — the mark of sovereignty and independence: the entity conducts its own foreign affairs, not subject to another State’s control. This is the element that distinguishes a State from a mere province or a puppet.

These are facts, not favours — an entity either has them or it does not (that is the declaratory view; see Topic 2 on recognition).

Now the kinds of States, because the examiner sets these as short notes. Keep them as a labelled list:

A. Sovereign (independent) State

The full, normal State — complete internal and external sovereignty (India, France).

B. Federal State and Confederation

A federal State (USA, India) is a single international person: the federation, not its units, conducts foreign relations. A confederation is a looser league of States that each keep their own international personality.

C. Protectorate and vassal State

A protectorate hands over control of its foreign affairs to a stronger “protecting” State by treaty, keeping internal self-government (e.g. old Bhutan–India relations). A vassal State is under the suzerainty of another and has almost no international personality of its own.

D. Condominium

A territory over which two or more States jointly exercise sovereignty (historically the New Hebrides, governed jointly by Britain and France; Sudan under Britain and Egypt). One land, shared sovereignty.

E. Micro-State (miniature State)

A fully sovereign but very small State (Monaco, San Marino, Liechtenstein, Nauru, the Vatican). It meets all four criteria; only its size is unusual. Micro-States can be UN members.

F. Neutralised State

A State whose permanent neutrality is guaranteed by treaty (historically Switzerland): it agrees never to go to war except in self-defence, and others guarantee its independence.

Article 1, Montevideo Convention (1933): “The State as a person of international law should possess the following qualifications: (a) a permanent population; (b) a defined territory; (c) government; and (d) capacity to enter into relations with the other States.”

In Simple Terms: To be a State you need people, land, a government running them, and independence enough to deal with other countries on your own. Miss the fourth — independence — and you are a province or a puppet, not a State, however large you are.

🧩 WORKED EXAMPLE — is entity X a State?

Facts. A territory has 40,000 settled inhabitants, clear borders, an effective government — but by treaty its defence and foreign policy are wholly controlled by a neighbouring power.

Rule. Montevideo Art. 1: all four elements are needed, and the fourth (capacity to enter into relations = independence) is decisive.

Apply. It satisfies population, territory and government, but not independent capacity — its foreign affairs are run by another State. It is at best a protectorate/vassal, not a full sovereign State.

Conclusion. Not a State in the full sense; small size (element 1) would be no bar, but loss of independent foreign-relations capacity is fatal.

Case Laws

• Deutsche Continental Gas-Gesellschaft v. Polish State (1929) — a State exists as soon as it has the four elements; frontiers need not be finally settled.
• Island of Palmas Case (1928) — sovereignty means independence: “the right to exercise therein, to the exclusion of any other State, the functions of a State”.
