List of national legal systems
The contemporary national legal systems are generally based on one of four major legal traditions: civil law, common law, customary law, religious law or combinations of these. However, the legal system of each country is shaped by its unique history and so incorporates individual variations. The science that studies law at the level of legal systems is called comparative law.
Both civil and common law systems can be considered the most widespread in the world: civil law because it is the most widespread by landmass and by population overall, and common law because it is employed by the greatest number of people compared to any single civil law system.
Civil laws
The source of law that is recognized as authoritative is codifications in a constitution or statute passed by legislature, to amend a code.While the concept of codification dates back to the Code of Hammurabi in Babylon ca. 1790 BC, civil law systems derive from the Roman Empire and, more particularly, the Corpus Juris Civilis issued by the Emperor Justinian ca. AD 529. This was an extensive reform of the law in the Byzantine Empire, bringing it together into codified documents. Civil law was also partly influenced by religious laws such as Canon law and Islamic law. Civil law today, in theory, is interpreted rather than developed or made by judges. Only legislative enactments are considered legally binding.
Scholars of comparative law and economists promoting the legal origins theory usually subdivide civil law into distinct groups:
- French civil law: in France, the Benelux countries, Italy, Romania, Spain and former colonies of those countries, mainly in Latin America, Africa and the Middle East;
- German civil law: in Germany, Austria, Russia, Switzerland, Estonia, Latvia, Bosnia and Herzegovina, Croatia, Kosovo*, North Macedonia, Montenegro, Slovenia, Serbia, Greece, Portugal and its former colonies, Turkey, and East Asian countries including Japan, South Korea, and Taiwan ;
- Scandinavian civil law: in Northern Europe such as Denmark, Norway, Finland, Iceland and Sweden. As historically integrated into the Scandinavian cultural sphere, Finland and Iceland also inherited the system, although especially Iceland has its own legal roots. Scandinavian or Nordic civil law exhibit least similar traits with other civil law systems and is sometimes considered a legal system in its own right, despite reception from mainly German civil law.

A comprehensive list of countries that base their legal system on a codified civil law follows:

![]() Common lawCommon law and equity are systems of law whose sources are the decisions in cases by judges. In addition, every system will have a legislature that passes new laws and statutes. The relationships between statutes and judicial decisions can be complex. In some jurisdictions, such statutes may overrule judicial decisions or codify the topic covered by several contradictory or ambiguous decisions. In some jurisdictions, judicial decisions may decide whether the jurisdiction's constitution allowed a particular statute or statutory provision to be made or what meaning is contained within the statutory provisions. The common law developed in England, influenced by Anglo-Saxon law and to a much lesser extent by the Norman conquest of England, which introduced legal concepts from Norman law, which, in turn, had its origins in Salic law. Common law was later inherited by the Commonwealth of Nations, and almost every former colony of the British Empire has adopted it. The doctrine of stare decisis, also known as case law or precedent by courts, is the major difference to codified civil law systems.Common law is practised in Canada, Australia, New Zealand, most of the United Kingdom, South Africa, Ireland, India, Pakistan, Hong Kong, the United States, Bangladesh, and many other places. Several others have adapted the common law system into a mixed system; For example, Nigeria operates largely on a common law system in the southern states and at the federal level, but also incorporates religious law in the northern states. In the European Union, the Court of Justice takes an approach mixing civil law with an attachment to the importance of case law. One of the most fundamental documents to shape common law is the English Magna Carta, which placed limits on the power of the English Kings. It served as a kind of medieval bill of rights for the aristocracy and the judiciary who developed the law.
