Key Concepts of International Law

International law sets the rules for how states interact, focusing on principles like sovereignty, non-intervention, and human rights. Understanding these principles helps us grasp the complexities of global relations and the importance of maintaining peace and cooperation among nations.

1. State sovereignty

   • States have the ultimate authority over their territory and domestic affairs.
   • Sovereignty implies independence from external control or interference.
   • It is a foundational principle of international law, ensuring states can govern themselves.

2. Non-intervention

   • States should not interfere in the internal affairs of other states.
   • This principle upholds state sovereignty and promotes peaceful coexistence.
   • Exceptions exist, such as humanitarian intervention or UN Security Council actions.

3. Prohibition of use of force

   • The use of armed force against another state is generally prohibited under international law.
   • Exceptions include self-defense and actions authorized by the UN Security Council.
   • This principle aims to maintain international peace and security.

4. Peaceful settlement of disputes

   • States are encouraged to resolve conflicts through negotiation, mediation, or arbitration.
   • This principle helps prevent escalation into armed conflict.
   • International organizations, like the UN, often facilitate these processes.

5. Self-determination of peoples

   • Peoples have the right to determine their political status and pursue their economic, social, and cultural development.
   • This principle supports decolonization and the rights of minority groups.

8. Pacta sunt servanda (agreements must be kept)

   • States are bound to honor their international agreements and treaties.
   • This principle promotes trust and stability in international relations.
