The United States antitrust law is the body of laws that prohibits anti-competitive behavior (monopoly) and unfair business practices. Antitrust laws are intended to encourage competition in the marketplace. These competition laws make illegal certain practices deemed to hurt businesses or consumers or both, or generally to violate standards of ethical behavior. Government agencies known as competition regulators, along with private litigants, apply the antitrust and consumer protection laws in hopes of preventing market failure. The term antitrust was originally formulated to combat \"business trusts\", now more commonly known as cartels. Other countries use the term \"competition law\". Many countries including most of the Western world have antitrust laws of some form; for example the European Union has provisions under the Treaty of Rome to maintain fair competition, as does Australia under its Trade Practices Act 1974.
