Several good websites on Roman law make it less necessary to give here detailed and extensive information. We treat here successively of the history of Roman law, its structure, character and content, the sources – and modern translations – and the modern scientific literature. At the bottom of this page there are links to important sites on Roman law.
History of Roman law
The earliest history of Roman law is lost forever. Rome existed already as an Etruscan town in the eight century B.C. The first known source of Roman law are the Laws of the Twelve Tables from the mid-fifth century B.C., written in early Latin. After the period of the kings two consuls and the Senate governed Rome. Only few people knew something of the law before the Twelve Tables were erected to provide some legal security. Members of well-to-do families, most of them patricians and senators, gave juridical advice when asked for. The Senate itself proposed laws or voted on proposals of the consuls. More is known about the period of the Late Republic (200-30 B.C.). The praetor, one of the Roman magistrates, published each year his edict in which he announced how he would apply the laws. The censors had a legal task, too, the upholding of mores. From Cicero’s pleas and letters one gets a vivid picture of actual jurisdiction during the Late Republic. Legal experts started to write books. In this period Rome had grown from a tiny city state into a vast reign.

During the Principate great jurists were active, who were sometimes employed by the emperor. Famous among them were Ulpian, Papinian, Paul and Julian. The mysterious Gaius wrote an introductory law book, the Institutes, almost the only completely surviving manual. The letters of governor Pliny show some of the legal questions he posed to the emperor. The praetorial edict became fixed. Emperor Theodosian tried to impose some legal order with his code of law. During the confusing times of the Late Imperium Justinian (early sixth century) tried to unify law by codification on all levels. Imperial decrees were collected and edited into a new Code, followed by later decrees, the Novellae. Justinian also charged a committee with making an anthology of the classical Roman lawyers, the Digestae or Pandectae. To crown his achievement, Justinian decreed a manual of law compulsory for all legal education. His Institutes are written using Gaius’ Institutes. The Justinian codification was the starting point for the new study, renewal and revival of Roman law during the Middle Ages.
The structure, character and content of Roman law
Roman law is first and foremost private law, law of and between citizens. In relation to it public law and the law of nations are less important. Roman law is concerned with the relationships between people, their legal actions, and the right they have on goods. Legal persons were in particular the fathers of families, the proverbial pater familias. They held great power over their wives, children and slaves. An important element is the law of procedure. The archaic Roman law was characterized by a lot of ritualized legal formulae to which one had to stick as close as possible. In a later phase one is able to choose one or more legal actions, a matter which called for interpretation: which action? Parties ruled their conflicts themselves. A judge only appeared in a final phase of the case. For centuries there were no courts. In the great public trials, like the ones in which Cicero became famous, his role was more akin to that of an orator than to the role of a modern solicitor.
Roman law is remarkable for the detailed yet succinct way one treated cases. One looked principally at things by dealing with concrete or imaginary cases (see the examples). This casuistic aspect is more important than any systematic view. One did not write a theory of damage, but about a car hitting someone on the Capitol (see D. 188.8.131.52). Of course one has tried to systematize Roman law. The great Roman lawyers treated all kind of cases when writing on several subjects or commenting the edict of the praetor. The real heart of Roman law was hereditary law. Apart from legal procedure, family law, the law of goods, and the law of obligations are the other main areas. The juridical content and level of Roman law has such quality that it has deeply influenced directly and indirectly lawyers of all times and places. It brought with it great prestige because of Roman history.
Sources of Roman law
During the ages many sources have been lost forever. Scholars divide the sources into pre-Justinian and Justinian, edited and codified in the sixth century. One has reconstructed the Twelve Tables from the works of later lawyers. The praetorial edict has been transmitted in the same way, and could therefore be reconstructed. The Code of Justinian preserves decrees of earlier emperors. Thanks to their inscriptions we know which emperor pronounced which decree. The Digest was made from a large collection of legal works into an anthology centered mostly around some of the great classical lawyers. The inscription at every lex or law give a clue to its origin, and thus we know many of these authors and a number of their works. The laws have been organised around particular subjects in tituli. These tituli have been gathered into 50 libri. In some modern languages, including English, exist modern translations of the sources within the Corpus Iuris Civilis.
