Ius gentium

Ius gentium, or the "law of nations," refers to the set of legal principles that govern the interactions between different countries and their citizens. Originating in Roman law, it shaped international law by establishing fair treatment, diplomatic relations, and rules for trade and war. Today, it influences global agreements and organizations, promoting consistent standards for resolving disputes and ensuring cooperation among nations. Essentially, ius gentium creates a shared legal framework that helps states and individuals navigate international relationships peacefully and justly.
