Step 1: Montevideo Convention (1933)
- It is an international treaty that defines the criteria for statehood in international law.
- It sets out the four criteria: a permanent population, defined territory, government, and capacity to enter into relations with other states.
Step 2: Other options
- Law of the Sea deals with maritime boundaries, not state definitions.
- Law of Treaties governs how treaties are made and followed.
- International Criminal Law relates to crimes against humanity and individuals, not statehood.
Hence, the Montevideo Convention provides the definition of a "state".
