Law

The roots of the legal principles and practices of the ancient Romans may be traced to the Law of the Twelve Tables promulgated in 449 BC and to the codification of law issued by order of Emperor Justinian I around 530 AD (see Corpus Juris Civilis). Roman law as preserved in Justinian's codes continued into the Byzantine Roman Empire, and formed the basis of similar codifications in continental Western Europe. Roman law continued, in a broader sense, to be applied throughout most of Europe until the end of the 17th century.

The major divisions of the law of ancient Rome, as contained within the Justinian and Theodosian law codes, consisted of Jus civile, Jus gentium, and Jus naturale. The Jus civile ("Citizen Law") was the body of common laws that applied to Roman citizens. The praetores urbani (sg. Praetor Urbanus) were the people who had jurisdiction over cases involving citizens. The Jus gentium ("Law of nations") was the body of common laws that applied to foreigners, and their dealings with Roman citizens. The praetores peregrini (sg. Praetor Peregrinus) were the people who had jurisdiction over cases involving citizens and foreigners. Jus naturale encompassed natural law, the body of laws that were considered common to all beings.
