1. What Is International Law?
International law refers to the set of rules and agreements that govern relations between nations, organizations, and sometimes individuals. Unlike domestic law, which is enforced by governments, international law relies on treaties, conventions, and cooperation among states.
Two Main Categories
Public International Law – Governs relationships between states and international organizations. (e.g., human rights law, environmental law, laws of war)
Private International Law – Governs cross-border disputes between private individuals or companies. (e.g., international contracts, family law across borders)

2. Key Sources of International Law
International law is not written in one book — it comes from multiple sources recognized by the International Court of Justice (ICJ):
Treaties & Conventions – e.g., Paris Climate Agreement, Geneva Conventions
Customary International Law – Long-standing practices accepted as law
General Principles of Law – Basic legal ideas recognized worldwide
Judicial Decisions & Scholarly Writings – ICJ judgments, academic contributions

3. Major International Legal Institutions
Several global and regional organizations shape international law:
United Nations (UN) – Maintains peace and security
International Court of Justice (ICJ) – Resolves disputes between nations
World Trade Organization (WTO) – Governs trade rules
International Criminal Court (ICC) – Tries individuals for war crimes and crimes against humanity
Regional Courts – e.g., European Court of Human Rights, Inter-American Court of Human Rights
