Law is a system of rules and guidelines which are enforced through social institutions to govern behavior, wherever possible. Laws are made by governments, and nowadays more specifically, by parliaments. It shapes politics, economics and society in numerous ways and serves as a social mediator of relations between people. Contract law regulates everything from buying a bus ticket to trading on derivatives markets. Property law regulates the transfer and title of personal property and real property. Trust law applies to assets held for investment and financial security. Tort law allows claims for compensation if a person’s property are harmed. If the harm is criminalised in legislation, criminal law offers means by which the state can prosecute the perpetrator. Constitutional law provides a framework for the creation of law, the protection of human rights and the election of political representatives. Administrative law is used to review the decisions of government agencies. International law governs affairs between sovereign states in activities ranging from trade to military action. Writing in 350BC, the Greek philosopher Aristotle declared, “The rule of law is better than the rule of any individual.”

A general distinction can be made between civil law jurisdictions, which codify their laws, and common law systems, where judge made law is not consolidated. In some countries, religion informs the law. Law provides a rich source of scholarly inquiry, into legal history, philosophy, economic analysis or sociology. Law also raises important and complex issues concerning equality, fairness, and justice. “In its majestic equality”, said the author Anatole France in 1894, “the law forbids rich and poor alike to sleep under bridges, beg in the streets and steal loaves of bread.” In a typical democracy, the central institutions for interpreting and creating law are the three main branches of government, namely an impartial judiciary, a democratic legislature, and an accountable executive. To implement and enforce the law and provide services to the public, a government’s bureaucracy, the military and police are vital. While all these organs of the state are creatures created and bound by law, an independent legal profession and a vibrant civil society inform and support their progress.
