Law

The rules that govern societies — and how they are made, applied, and challenged

What Is Law?

Law is a system of rules created and enforced through social or governmental institutions to regulate behavior. It shapes politics, economics, history, and society in countless ways.

Legal Systems

• Common Law — based on judicial precedent (UK, US, Canada, Australia)
• Civil Law — based on comprehensive legal codes (France, Germany, Japan, most of continental Europe)
• Religious Law — derived from religious texts (Sharia, Halakha, Canon law)
• Customary Law — based on long-standing traditions of a community

Branches of Law

• Constitutional Law — the supreme law of a nation; defines government structure and rights
• Criminal Law — offenses against the state (theft, assault, murder)
• Civil Law — disputes between individuals or organizations (contracts, property, torts)
• Administrative Law — rules and regulations created by government agencies
