Understanding State Sovereignty and International Law

Defining Sovereign States in International Law

States are sovereign, independent entities recognized under international law. Today, the international community is composed of approximately 199 states. An independent state is defined as a community established in a territory, politically organized under a single government, and free from external authority.

Constituent Elements of a State

• Territory: The physical space—land, sea, or air—under state status. Precise territorial boundaries are not strictly required for statehood.
• Population: A human collectivity established within the territory on a stable and permanent basis.
• Government: The capacity to exercise effective control over the territory and its people while maintaining international relations.
• Independence: The state must conduct its external relations without subordination to another authority. Internally, it must be self-governing, capable of enacting laws, organizing public services, and exercising international powers such as concluding treaties and participating in global organizations.

Types of States

Federal States

In federal states, the constitution distributes competence regarding internal affairs between federal authorities and member states. However, the federal government retains exclusive control over external relations. At the international level, the federation acts as a single entity (e.g., Argentina).

Confederation of States

A confederation is an association of sovereign states based on a treaty. Common interests, such as defense, are regulated by a central body. Internationally, each confederated state preserves its individual character and independence, though the confederation may act within its specific jurisdiction.

Neutralized States

A neutralized state is one whose independence and integrity are permanently guaranteed by a treaty. In exchange, the state is obligated not to participate in wars between other nations, except in self-defense, and must avoid obligations that could drag it into conflict. A historical example is Switzerland, neutralized by the Congress of Vienna in 1815.
