Roman law

The Roman law refers to the legal framework of classical Rome, which encompasses more than a millennium of legal precedents. This includes the Twelve Tables, which date back to approximately 449 BC, and the Corpus Juris Civilis, which was imposed in AD 529 by Justinian I, the Eastern Roman emperor. The most common legal system in use today, civil law, is based on Roman law; in fact, the words are sometimes used interchangeably. Many legal systems, including common law, have been inspired by Roman law, as seen by the persistence of Latin legal terminology.

Roman law persisted throughout the Eastern Roman Empire following the fall of the Western Roman Empire. Greek was used as the legal language in the East starting in the seventh century.

Up until the end of the 18th century, the majority of Western Europe followed a legal system derived from Roman law. Under the Holy Roman Empire, Roman law was more persistently practiced in Germany (963–1806). Thus, Roman law formed the foundation for legal practice not only in Ethiopia but also in most of the former colonies of major European countries, including Latin America and Western continental Europe.

Roman law also had an impact on Anglo-American and English common law, particularly on its Latinate legal lexicon (stare decisis, culpa in contrahendo, pacta sunt servanda, etc.).(Source: ) The Corpus Juris Civilis’s jurisprudence significantly affected Eastern Europe, particularly in nations like medieval Romania (Wallachia, Moldavia, and a few other medieval provinces/historical regions).

Development of Roman Law

Roman civil law (ius civile Quiritium) prior to the Twelve Tables (754–449 BC) was made up of private law, which was tied to religion and applied only to Roman citizens. It was undeveloped and had elements of strict formalism, symbolism, and conservatism, such as the ceremonial practice of mancipatio (a type of sale). Sextus Pomponius, a jurist, stated, “At the beginning of our city, the people began their first activities without any fixed law, and without any fixed rights: all things were ruled despotically, by kings” .[/2] Roman law is thought to have its origins in Etruscan religion, which placed a strong emphasis on ritual.[/3]

Twelve Tables

The Law of the Twelve Tables, which dates to the middle of the fifth century BC, is the oldest known legal treatise. C. Terentilius Arsa, a plebeian tribune, suggested that the law be drafted to stop magistrates from enforcing it arbitrarily.[4] The plebeian social class persuaded the patricians to send a delegation to Athens to duplicate the Laws of Solon after eight years of political conflict; they also sent delegates to other Greek cities for the same purpose.[4]

The conventional account (as told by Livy) is that in 451 BC, 10 Roman citizens were selected to write down the laws, or decemviri legibus scribundis. They were granted imperium, or absolute political power, while they carried out this duty, whereas the magistrates’ authority was limited.*[4]

Latin historians are not always believed to be accurate by contemporary scholars.

In general, they deny the existence of a second decemvirate. The most contentious aspects of customary law are thought to have been covered by the decemvirate of 451 BC, who also rose to prominence in Rome.[4] Moreover, there is still a great deal of debate over the Greek effect on early Roman law. The Latin historians claimed that the patricians dispatched an official embassy to Greece, although many researchers doubt this. Rather, other researchers propose that the Greek laws were obtained by the Romans from the Greek cities of Magna Graecia, which served as the primary entry point between the Greek and Roman civilizations.[4]

The Twelve Tables’ original text is no longer in existence. It is likely that the tablets were destroyed during the conquest of Rome.

Early law and jurisprudence

The most important laws enacted in the early Republic were the Lex Canuleia (445 BC), which allowed plebeians and patricians to marry (conubium); the Leges Liciinae Sextiae (367 BC), which limited the amount of public land (ager publicus) that any citizen could occupy and required plebeians to elect one of the two annual consuls;[5] the Lex Ogulnia (300 BC), which allowed plebeians to hold certain priestly offices; and the Lex Hortensia (287 BC), which declared that decisions made by plebeian assemblies (plebiscita) would henceforth be binding on the entire populus Romanus, patricians and plebeians alike.(6)

The Lex Aquilia of 286 BC is another significant Republican statute that could be considered the forerunner of contemporary tort law.

But rather than passing well-written laws, Rome’s greatest contribution to European legal culture was the development of a legal science and a class of professional jurists known as prudentes or jurisprudentes, sing. prudens. This was accomplished by gradually adapting Greek philosophical scientific methodologies to the study of law—a subject that the Greeks themselves never considered to be a science.

Legal science in Rome is said to have its roots in Gnaeus Flavius. It is believed that Flavius published the formularies with the necessary words to speak in around 300 BC.

These formularies are supposed to have been confidential and known only by priests prior to the time of Flavius. Their release allowed non-priests to investigate the meaning of these legal documents. Regardless of the veracity of this account, before the second century BC, a greater number of legal treatises were created and jurists were active.

Famous jurists from the republican era include Marcus Tullius Cicero’s companion Servius Sulpicius Rufus and Quintus Mucius Scaevola, who authored a comprehensive treatise on all facets of the law that had a significant impact on subsequent generations. Thus, when the Roman republic gave way to the Principate’s monarchical regime in, Rome had already evolved a highly developed legal system and a sophisticated legal culture.

Pre-classical period

We can observe the emergence of more adaptable laws to meet the demands of the day in the roughly 201–27 BC period. A new legal class known as the ius honorarium is established in addition to the traditional and formal ius civile. Its definition is “The law introduced by the magistrates who had the right to promulgate edicts in order to support, supplement, or correct the existing law.”(7) The old formalism is being abandoned in favor of the new, more adaptable ius gentium principles with this new law.

It was left to the judiciary, magistrates, and particularly the praetors to adapt the law to new demands. In theory, a praetor did not enact new laws because they were not legislators.

Although a praetor’s successor was not constrained by his predecessor’s decrees, he did adopt regulations from those decrees that had shown to be beneficial. This resulted in the creation of a continual content that moved from edict to edict (edictum traslatitium).

As a result, a new corpus of praetoric law developed over time, complementing and improving civil law in parallel. The renowned Roman jurist Papinian (142–212 AD) actually defined praetoric law as follows: “Ius praetorium est quod praetores introduxerunt adiuvandi vel supplendi vel corrigendi iuris civilis gratia propter utilitatem publicam” (which translates to “praetoric law is that law introduced by praetors to supplement or correct civil law for public benefit”).

Classical Roman law

The height of the sophistication of Roman law and Roman legal science occurred in the first 250 years of the modern era. The term “classical period of Roman law” is frequently used to describe the legal system of this era.[Did who?] Roman law took on its distinct form as a result of the intellectual and practical accomplishments of the jurists of this time.

The jurists performed a variety of tasks, such as providing legal opinions upon request from individuals or organizations. They provided counsel to the magistrates, particularly the praetors, who were charged for carrying out the administration of justice. They assisted the praetors in drafting their edicts, which they used to publicly declare at the start of their term how they would carry out their responsibilities and the procedures that would be followed in particular cases.

The jurists also devised a wide range of legal penalties. The praetor’s edict was standardized by the jurist Salvius Iulianus around AD 130, and all praetors used it after that. This decree included thorough explanations of every situation in which the praetor would permit legal action and provide a defense.

For this reason, the standard edict served as a kind of complete legal code even if it lacked official legal power. It stated what had to be met in order for a lawsuit to be successful.

Thus, the edict served as the foundation for lengthy legal commentary written by Paulus and Ulpian, two later classical jurists. There are too many new ideas and legal frameworks created by classical and pre-classical jurists to include them all here.

Roman jurists distinguished between the factual capacity to use and control an object (possession) and the legal right to use it (ownership). Additionally, they defined the differences between tort and contract as the origins of legal obligations.


Roman jurisprudence produced the features of each of the standard contract types—sale, contract for work, contract for services, hire, and contract for services—that are controlled in the majority of continental codes.
The ancient jurist Gaius (c. 160–161) created a system of private law in his Institutes that divided everything into personae (persons), res (things), and actiones (legal activities). This was a method in operation for several centuries. Legal treatises such as William Blackstone’s Commentaries on the Laws of England and legislative acts.

Public law

The unwritten collection of rules and values known as the mos maiorum, or “custom of the ancestors,” of the Roman Republic was mostly passed down by precedent. Modern constitutions continue to incorporate ideas that were first introduced in the Roman constitution. Term limits, quorum requirements, impeachments, the purse powers, vetoes, filibusters, and regularly scheduled elections are a few examples of checks and balances. Roman constitutional principles are the source of even some less common contemporary constitutional notions, as block voting in the US electoral college.

The Roman Republic’s constitution was neither official nor formal. For most of the Republic’s existence, its constitution was unwritten and under constant change.

The authority and legitimacy of the Roman constitution were steadily declining during the first century BC. By the end of the Republic, even Roman constitutionalists like senator Cicero no longer felt compelled to uphold it. What remained of the Roman constitution perished along with the Roman Republic when it finally collapsed in the years after the Battle of Actium and Mark Antony’s suicide.

Using the institutions of the previous constitution to support Augustus’ greater imperium over the imperial provinces and the prorogation of various magistracies to support Augustus’ receipt of tribunician powers, Augustus, the first Roman emperor, attempted to create the appearance of a constitution that still governed the Empire.
