Ius gentium

Ius gentium, or 'the law of nations,' refers to a set of legal principles and norms that govern the interactions and relations between different nations and peoples. This concept evolved in ancient Rome as the Romans sought to establish a framework for dealing with foreign entities, integrating both natural law and customary practices into a cohesive legal system that transcended local laws.
