Legal theory is a field of study that examines the nature of law, its origins, its interpretation, and its role within societies. It explores questions such as what constitutes a valid law, the relationship between law and morality, the authority of legal systems, and the limits of legal enforcement. Legal theorists may draw upon various disciplines, including philosophy, sociology, political science, and economics, to analyze and critique the foundations of law and legal systems. Ultimately, legal theory seeks to understand the principles and values that underpin the legal order and inform the development and application of laws in society.
