The codices of Justinian, especially the Corpus Juris Civilis (529-534), continued to form the basis of legal practice in the empire during so-called Byzantine history. Leo III the Isaurian issued a new code, the Ecloga,[9] at the beginning of the 8th century. In the 9th century, Emperors Basil I and Leo VI the Wise commissioned a combined translation of the Codex and the Digest, parts of the Justinian codes, into Greek, which became known as the basilica. Roman law, as preserved in the codes of Justinian and in the basilica, remained the basis of legal practice in Greece and in the courts of the Eastern Orthodox Church even after the fall of the Byzantine Empire and the conquest by the Turks and, together with the Syro-Roman code of law, also formed the basis of much of the Fetha Negest. which remained in force in Ethiopia until 1931. Slavic legal traditions, including countries from Bulgaria to Russia, were greatly influenced by peasant law. [29] To a lesser extent, Ecloga and other Byzantine codices also influenced these regions. During the 18th and 19th centuries, as Russia strengthened its contacts with the West, the Code of Justinian began to be studied, which brought this influence. When the center of the empire was moved to the Greek East in the 4th century, many legal terms of Greek origin appeared in official Roman legislation.

[8] Influence is also visible in personal or family law, which is traditionally the part of the law that changes the least. For example, Constantine began to limit the ancient Roman concept of patria potestas, the power of the male head of the family over his descendants, by recognizing that the people in the potestate, the descendants, could have property rights. He apparently made concessions to the much stricter concept of paternal authority under Greek Hellenistic law. [8] The Codex Theodosianus (438 AD) was a codification of constant laws. Later, the emperors went even further until Justinian finally decreed that a child of Potestate would become the owner of everything he had acquired, unless he had acquired something from his father. [8] After the Islamic conquests of the Eastern Mediterranean, Islamic caliphates gradually codified their legal systems with Romano-Byzantine law as an important model. Indeed, it has been suggested that it was the publication of the Ecloga that stimulated the first major codification of Islamic imperial law. [28] In the absence of a competent and effective legal system, most judges and trials throughout the empire were conducted by simplified and popular laws such as peasant law, maritime laws, military laws or the lesser-known Mosaic law, the various orthodox and Hellenistic concepts, or orally by the effective and persuasive use of rhetoric. and not the legal provisions themselves, without Roman law being properly applied, systematized or continuous. [9] This chapter develops a working definition of the law and legal system that is used throughout the book.

The law is the set of rules and regulations applied by the government. However, formal law is only one part of a larger legal system that encompasses the structures, substance, and culture that bring law to life in books. Together, the law and the legal system function both as a method of social control and as a means of settling disputes. The final part of the chapter situates the American legal system within the broader realm of civil law and the common law system around the world. Traditionally, the origins of Roman jurisprudence are associated with Gnaeus Flavius. Flavius is said to have published around 300 BC. J.-C. the formulas with the words that had to be pronounced in court to bring a lawsuit.

Before the time of Flavius, these formulas would have been secret and known only to priests. Their publication allowed non-priests to explore the meaning of these legal texts. Whether this story is credible or not, jurists were active and legal treatises were written before the 2nd century BC. Written in greater numbers. Among the famous jurists of the Republican period are Quintus Mucius Scaevola, who wrote a vast treatise on all aspects of law, which later had a great influence, and Servius Sulpicius Rufus, a friend of Marcus Tullius Cicero. Thus, Rome had developed a very sophisticated legal system and a refined legal culture when the Roman Republic was replaced by the monarchical system of the Principate in 27 BC. Only England and the Nordic countries did not participate in the full reception of Roman law. One reason for this is that at the time of the rediscovery of Roman law, the English legal system was more developed than its continental counterparts. As a result, the practical benefits of Roman law were less obvious to English practitioners than to continental jurists. As a result, the English common law system developed alongside Roman civil law, its practitioners being trained at the Inns of Court in London, rather than obtaining degrees in canon or civil law at the universities of Oxford or Cambridge. Elements of Roman canon law were present in England in ecclesiastical courts and, less directly, through the development of the judicial system. In addition, some concepts of Roman law have found their way into the common law.

Especially in the early 19th century, English jurists and judges were ready to adopt the rules and ideas of continental jurists and directly Roman law. By the middle of the 3rd century, the conditions for the flourishing of a refined legal culture had become less favorable. The overall political and economic situation deteriorated as emperors gained more direct control over all aspects of political life. The political system of the Principality, which had retained some features of the republican constitution, began to transform itself into the absolute monarchy of the dominant. The existence of jurisprudence and jurists who regarded law as a science, and not as an instrument for achieving the political objectives of the absolute monarch, did not fit well into the new order of things. Literary production was almost complete. Only a few jurists after the middle of the 3rd century are known by name. While jurisprudence and legal education continued to exist to some extent in the eastern part of the empire, most of the subtleties of classical law were ignored and eventually forgotten in the West. The classical law has been replaced by the so-called vulgar law. Another important law of the Republican era is the Lex Aquilia of 286 BC.

J.-C., which can be considered the root of modern tort law. Rome`s most important contribution to European legal culture, however, was not the enactment of well-drafted laws, but the emergence of a class of professional jurists (prudent, sing. prudens or jurisprudent) and jurisprudence. This was achieved in a gradual process of applying the scientific methods of Greek philosophy to the subject of law, a subject that the Greeks themselves never treated as a science. Students who learned Roman law in Bologna (and later in many other places) found that many rules of Roman law were better suited to regulating complex economic transactions than the usual rules that applied throughout Europe. For this reason, Roman law, or at least some provisions borrowed from it, was reintroduced into legal practice centuries after the end of the Roman Empire. This process was actively supported by many kings and princes who employed university-trained jurists as advisors and court officials, trying to benefit from rules such as the famous Princeps legibus solutus est („The ruler is not bound by the laws“, a term originally coined by Ulpian, a Roman jurist). Roman law formed the basis of civil law used today in continental Europe and throughout Latin America. The common law, the other important legal body used in the world, developed in British courts in the Middle Ages and later spread to the United States and Commonwealth member states. After the reign of Justinian, the empire entered a period of rapid decline, which partly allowed Arab conquests that would further weaken the empire. Knowledge of Latin, which has been in decline since the fall of the West, has all but disappeared, making many old legal codes almost inaccessible.

These developments contributed to a dramatic weakening of legal norms in the Reich and a considerable decline in the norms of jurisprudence. [14] Legal practice would become much more pragmatic, and as knowledge of Latin declined in the empire, the direct use of Justinian`s „Corpus Juris Civilis“ was abandoned in favor of summaries, commentaries, and new compilations in Greek. To describe a person`s position in the legal system, the Romans mainly used the term togeus. The individual could have been a Roman citizen (status civitatis) as opposed to foreigners, or he could have been free (status libertatis) as opposed to slaves, or he could have held a certain position in a Roman family (status familiae), either as head of the family (pater familias) or as a lower member – alieni iuris – living according to someone else`s law. Two types of status were senator and emperor. The following legal texts were written in the later Byzantine Empire: Today, Roman law is no longer applied in legal practice, although the legal systems of some countries such as South Africa and San Marino are still based on the ancient ius commune. But even when legal practice is based on a code, many rules derived from Roman law apply: no code has completely broken with Roman tradition. On the contrary, the provisions of Roman law have been inserted into a more coherent system and expressed in the national language. For this reason, knowledge of Roman law is essential to understanding today`s legal systems.
