Montevideo Convention on the Rights and Duties of States (1933)
Overview
The Montevideo Convention on the Rights and Duties of States was adopted on 26 December 1933.
It was signed during the Seventh International Conference of American States in Montevideo, Uruguay.
The convention codified key principles of international law relating to:
statehood
sovereignty
non-intervention.
It remains one of the most widely cited legal frameworks for defining a state in international law.
Historical background
The early 20th century saw political instability and regime changes in Latin America, creating disputes over recognition of states and governments.
The convention emerged partly from the Good Neighbour Policy of the United States, which promoted:
mutual respect among American states
non-intervention
sovereign equality.
Key facts
Adopted: 1933
Ratified by the United States: 1934
Number of signatories: 19 American states.
Criteria for statehood (Article 1)
The convention defines four essential elements required for an entity to be considered a state:
Permanent population
A stable community of people residing within the state.
Defined territory
A specific geographical area under the authority of the state.
Exact borders need not be fully settled.
Government
An organised political authority capable of maintaining order and governance.
Capacity to enter into relations with other states
Ability to conduct foreign relations and diplomacy independently.
These four criteria are widely treated as the customary definition of statehood in international law.
Declarative theory of statehood
The convention supports the Declarative Theory of Statehood.
Key idea
A state exists if it fulfils the four criteria, regardless of whether other states recognise it.
Contrast with another theory
Constitutive theory of statehood
A state exists only when recognised by other states.
Thus:
Theory | Core Idea |
Declarative theory | Statehood depends on objective criteria |
Constitutive theory | Statehood depends on recognition by other states |
Principle of non-intervention
The convention strongly emphasised non-intervention.
Article 8 states:
No state has the right to intervene in the internal or external affairs of another state.
Significance
Particularly important in Latin America, where foreign intervention had been frequent.
Strengthened the doctrine of sovereignty and independence of states.
Sovereign equality of states
The convention reinforced the idea that:
All states are legally equal, regardless of size, power, or economic status.
This principle later became a core foundation of modern international law and global governance.
Signatories
The convention was signed by 19 American countries, including:
United States
Argentina
Brazil
Chile
Mexico
Uruguay.
Although originally a regional treaty, its principles have influenced global international law.
