Law is a set of rules that helps people live together. These rules are made by governments or groups in society. They help regulate how people behave toward one another. Some people call law a science. Others call it the art of justice. 
Legal systems are often split into two main groups. One group is called civil law. In these systems, a central body writes down and organizes the laws into codes. The other group is called common law. In common law systems, judges make binding rules through their decisions. Sometimes a higher court or a legislature can change these rules. 
Law can be divided into public and private areas. Public law deals with the government and society. This includes criminal law and constitutional law. Private law deals with disputes between individuals. Examples include rules about property or contracts. 
People have been making laws for thousands of years. In ancient Sumer, a ruler named Ur-Nammu made a law code around the 22nd century BC. Later, King Hammurabi of Babylon wrote his own code around 1760 BC. He carved his laws into stone pillars called stelae. 
Different parts of the world have unique traditions. Ancient India used important texts like the Manusmriti. In China, legal traditions were very distinct. Japan was one of the first to modernize its laws using Western styles. They used parts of the French system and the German Civil Code. Today, many legal systems are starting to look more alike. For example, EU law uses treaties and court decisions. This shows how law is always changing and growing.
Law is a structured set of rules created by institutions. These institutions can be governments or entire societies. The purpose of law is to regulate human behavior. Some scholars describe law as a science. Others view it as the art of justice.
Different authorities create different types of law. A legislature creates statutes, which are written laws. An executive branch can issue decrees or regulations. In common law jurisdictions, judges create precedent through their decisions. This means past court rulings guide future cases. An autocrat might exercise all these powers within their own realm. The specific way laws are made often depends on the legal system in place. 
Legal systems are generally divided into several major categories. Civil law jurisdictions use a central body to codify the law. Codification means organizing laws into a clear, written code. Common law systems rely on judges to make binding case law. This case law is established through the principle of precedent. Religious law is also used by certain states and communities. Historically, religious law has influenced many secular legal systems. 
Law is also categorized by its specific scope. Public law concerns the relationship between government and society. This domain includes constitutional, administrative, and criminal law. Private law deals with disputes between individual parties. Examples of private law include contracts, property, and commercial law. The distinction between public and private law is very strong in civil law countries. In common law jurisdictions, this divide is often less pronounced. 
Philosophers study law through a field called jurisprudence. Normative jurisprudence asks what the law should be. Analytic jurisprudence asks what the law actually is. H. L. A. Hart argued that law is a system of rules. He divided these into primary rules of conduct and secondary rules. Secondary rules help officials administer the law. They include rules of adjudication to resolve disputes and rules of change.
History shows that law has grown alongside civilization. In ancient Sumer, Ur-Nammu formulated a law code around the 22nd century BC. Around 1760 BC, King Hammurabi of Babylon created the Codex Hammurabi. He inscribed these laws on stone stelae for the public to see. 
Different regions developed unique legal traditions. Ancient India used foundational texts like the Manusmriti. In the Indian subcontinent, sharia was established by various sultanates. In East Asia, Japan modernized its system by importing the German Civil Code. Today, many systems are converging. For example, EU law is codified in treaties but also uses court precedents. This shows how law remains a dynamic and evolving force in the world.
