What Is Law?


Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. It can include a written constitution, or a tacit agreement to follow the rules.

There are four principal purposes of law: to establish standards, maintain order, resolve disputes and protect liberties and rights. In addition, law is an important source of scholarly inquiry into legal history, philosophy, economic analysis and sociology.

In a modern society, laws are enacted by politicians, often based on political parties’ manifestos, and often enforced through police forces. Unstable or authoritarian governments often fail to serve these functions.

The judicial process is another important part of law, as judges decide how the rules should be applied. Courts have the power to impose fines and jail people for breaking the law, and can also award damages or compensation for harm done.

Criminal law is the study of how people can be charged with crimes, such as assault or fraud. It can also involve how people can be convicted of murder, theft or other serious crimes.

Civil law is the study of relationships between people, such as family, marriage and divorce, or the rights of workers. It can also include issues like immigration and nationality.

International law is a broad field of law that covers the laws of nations. It includes treaties, international agreements and the law of states in their relations with other countries.

Property law deals with rights to real estate and personal possessions. It includes land and other movable goods, as well as intangible rights such as stocks and shares.

It is divided into several branches: real estate, commercial and intellectual property. It is also regulated by various statutory systems, including mortgages, leases and land registration.

The word “law” comes from the Old Testament’s Mosaic covenant, which focused on God’s commands and regulations.

Traditionally, the legal system has been derived from religious precepts, especially in a Jewish context and in Islamic communities. In these cases, religion can be a powerful force in settling legal disputes.

In modern societies, there are three types of law: (a) common law; (b) civil law; and (c) international law. The three systems differ in how they codify their legal system and how they are administered.

Common law systems have judges who interpret laws through precedent, while civil law systems usually have a legislature that passes legislation and regulations. These are then interpreted by judges through case law.

Some jurisdictions also use a form of administrative law, which is similar to the common law but is not formally codified. It can include regulations that are issued by government agencies, such as the Occupational Safety and Health Administration.

Law is a complex subject and is sometimes referred to as the ‘language of government’ because it provides a governing framework for how people interact in society. It is therefore a major subject of public policy debates.
