This episode explores how law emerged as humanity’s answer to violence, uncertainty, and conflict. It begins with early tribal customs, where social rules were enforced informally through revenge or exile, and explains how growing populations required more permanent forms of justice. The episode traces the earliest written laws, such as the Code of Hammurabi, which shifted justice from personal vengeance to institutional rule. It examines how rulers legitimized laws through divine authority, how empires like Rome and China used law for administration, and how later revolutions transformed law from a tool of kings to a contract protecting citizens. While acknowledging that laws have often been used to oppress, the episode emphasizes that law is humanity’s most powerful invention for replacing chaos with order — a system that evolves as society demands fairness and accountability.
