National legal systems are the frameworks of laws and regulations that govern a specific country. Each system is shaped by the nation's history, culture, and social values, leading to variations in how laws are created, interpreted, and enforced. Common types of legal systems include civil law, common law, and religious law, each with distinct characteristics and procedures. These legal systems serve to maintain order, protect individual rights, and resolve disputes. They are typically composed of various components, such as legislation, judiciary, and administrative agencies, which work together to ensure justice and uphold the rule of law within the nation.
