In the Roman Dominate and Latin jurisprudence down to the 18th century, the lex regia (literally, "royal law" or "royal act") was the supposed law by which unlimited imperium or authority had been transferred from the Roman people to the emperor. Emperor Justinian summarised the law in the decree by which he established the commission to compile the Digest in AD 530, Deo auctore: "By an ancient law [lege antiqua], which was called 'royal' [regia], all the authority and all the power of the Roman people were transferred to the power of the emperor." The concept originates somewhat earlier, however: Ulpian, in the early 3rd century, may already have referred to the law, though the meaning and even the authenticity of his use of the term are contested. [1]
In the commentaries of the medieval glossators and postglossators, which took Justinian's Corpus Juris Civilis as their starting point, there was debate as to whether the lex regia had constituted a single, irrevocable act by which supreme power or sovereignty had been permanently alienated from the people to the emperor. [2] It was the standard view of early glossators such as Irnerius that the transfer of power had been permanent and irrevocable, [3] and a similar conclusion was endorsed later on by Bartolus de Saxoferrato (1313–1357), who considered that the law had been sanctified by Jesus Christ and the pope as his vicar, and was thus no longer subject to human revocation. Paulus Castrensis (died 1441) concluded on the same basis that "nowadays the Roman people can do nothing in the empire". [4]
At the turn of the 13th century, however, Azo of Bologna argued that the power delegated by the lex regia had always remained at the disposal of the Roman people: "My own view", he wrote, "is that the people never transferred this power except in such a way that they were at the same time able to retain it themselves." [3] A similar view would be articulated by the Monarchomachs of the Reformation era: the Vindiciae contra tyrannos (1579) cited the lex regia to argue that the people had delegated their power only as a concession, and that as a corporate body (universitas) they remained superior to the king. [5] By the 17th century, the lex regia could accordingly be interpreted by republicans such as John Milton as a proof of the emergent theory of popular sovereignty. [6]
After the rediscovery of the inscribed lex de imperio Vespasiani in the 14th century by Cola di Rienzo, [7] the lex regia was often identified with the lex curiata de imperio , a type of law that empowered higher Roman magistrates—Jean Bodin, indeed, believed that the Vespasianic law was itself the lex regia that permanently established the imperial office. [8] Yet the lex de imperio Vespasiani did not purport to confer upon Vespasian unlimited, monarchical authority, and the term regia itself would have been unusual in the constitutional context of the Principate, which was not officially a monarchy. [1] Modern scholars thus reject the historical existence of a lex regia in the form discussed by Justinian and later civilians, considering it a late Roman invention intended to explain the transition from a republican to monarchical form of government.

Justinian I, also known as Justinian the Great, was the Eastern Roman emperor from 527 to 565.
Roman law is the legal system of ancient Rome, including the legal developments spanning over a thousand years of jurisprudence, from the Twelve Tables, to the Corpus Juris Civilis ordered by Eastern Roman emperor Justinian I. Roman law forms the basic framework for civil law, the most widely used legal system today, and the terms are sometimes used synonymously. The historical importance of Roman law is reflected by the continued use of Latin legal terminology in many legal systems influenced by it, including common law.
Sovereignty can generally be defined as supreme authority. Sovereignty entails hierarchy within the state, as well as external autonomy for states. In any state, sovereignty is assigned to the person, body, or institution that has the ultimate authority over other people in order to establish a law or change existing laws. In political theory, sovereignty is a substantive term designating supreme legitimate authority over some polity. In international law, sovereignty is the exercise of power by a state. De jure sovereignty refers to the legal right to do so; de facto sovereignty refers to the factual ability to do so. This can become an issue of special concern upon the failure of the usual expectation that de jure and de facto sovereignty exist at the place and time of concern, and reside within the same organization.
The Corpus JurisCivilis is the modern name for a collection of fundamental works in jurisprudence, issued from 529 to 534 by order of Justinian I, Byzantine Emperor. It is also sometimes referred to metonymically after one of its parts, the Code of Justinian.
The judiciary is the system of courts that adjudicates legal disputes/disagreements and interprets, defends, and applies the law in legal cases.
Public law is the part of law that governs relations between legal persons and a government, between different institutions within a state, between different branches of governments, as well as relationships between persons that are of direct concern to society. Public law comprises constitutional law, administrative law, tax law and criminal law, as well as all procedural law. Laws concerning relationships between individuals belong to private law.
The Western Roman Empire comprised the western provinces of the Roman Empire at any time during which they were administered by a separate independent Imperial court; in particular, this term is used in historiography to describe the period from 395 to 476, where there were separate coequal courts dividing the governance of the empire in the Western and the Eastern provinces, with a distinct imperial succession in the separate courts. The terms Western Roman Empire and Eastern Roman Empire were coined in modern times to describe political entities that were de facto independent; contemporary Romans did not consider the Empire to have been split into two empires but viewed it as a single polity governed by two imperial courts as an administrative expediency. The Western Roman Empire collapsed in 476, and the Western imperial court in Ravenna was formally dissolved by Justinian in 554. The Eastern imperial court lasted until 1453.
A consul was the highest elected public official of the Roman Republic. Romans considered the consulship the second-highest level of the cursus honorum—an ascending sequence of public offices to which politicians aspired—after that of the censor. Each year, the Centuriate Assembly elected two consuls to serve jointly for a one-year term. The consuls alternated each month holding fasces when both were in Rome. A consul's imperium extended over Rome and all its provinces.
Byzantine law was essentially a continuation of Roman law with increased Orthodox Christian and Hellenistic influence. Most sources define Byzantine law as the Roman legal traditions starting after the reign of Justinian I in the 6th century and ending with the Fall of Constantinople in the 15th century. Although future Byzantine codes and constitutions derived largely from Justinian's Corpus Juris Civilis, their main objectives were idealistic and ceremonial rather than practical. Following Hellenistic and Near-Eastern political systems, legislations were tools to idealize and display the sacred role and responsibility of the emperor as the holy monarch chosen by God and the incarnation of law "nómos émpsychos", thus having philosophical and religious purposes that idealized the perfect Byzantine king.
The term Thraco-Roman describes the Romanized culture of Thracians under the rule of the Roman Empire.
The Roman Senate was a governing and advisory assembly in ancient Rome. It was one of the most enduring institutions in Roman history, being established in the first days of the city of Rome. It survived the overthrow of the Roman monarchy in 509 BC; the fall of the Roman Republic in the 1st century BC; the division of the Roman Empire in AD 395; and the fall of the Western Roman Empire in 476; Justinian's attempted reconquest of the west in the 6th century, and lasted well into the Eastern Roman Empire's history.
The Roman Assemblies were institutions in ancient Rome. They functioned as the machinery of the Roman legislative branch, and thus passed all legislation. Since the assemblies operated on the basis of a direct democracy, ordinary citizens, and not elected representatives, would cast all ballots. The assemblies were subject to strong checks on their power by the executive branch and by the Roman Senate. Laws were passed by Curia, Tribes, and century.
The legislative assemblies of the Roman Empire were political institutions in the ancient Roman Empire. During the reign of the second Roman Emperor, Tiberius, the powers that had been held by the Roman assemblies were transferred to the senate. The neutering of the assemblies had become inevitable for reasons beyond the fact that they were composed of the rabble of Rome. The electors were, in general, ignorant as to the merits of the important questions that were laid before them, and often willing to sell their votes to the highest bidder.
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued, modern historians distinguish the Byzantine Empire from the earlier Roman Empire due to the imperial seat moving from Rome to Byzantium, the Empire's integration of Christianity, and the predominance of Greek instead of Latin.
In the constitution of ancient Rome, the lex curiata de imperio was the law confirming the rights of higher magistrates to hold power, or imperium. In theory, it was passed by the comitia curiata, which was also the source for leges curiatae pertaining to Roman adoption.
Christianity became the official religion of the Roman Empire when Emperor Theodosius I issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy of Nicene Christians in the Great Church as the Roman Empire's state religion. Most historians refer to the Nicene church associated with emperors in a variety of ways: as the catholic church, the orthodox church, the imperial church, the imperial Roman church, or the Byzantine church, although some of those terms are also used for wider communions extending outside the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church all claim to stand in continuity from the Nicene church to which Theodosius granted recognition.
Medieval Roman law is the continuation and development of ancient Roman law that developed in the European Late Middle Ages. Based on the ancient text of Roman law, Corpus iuris civilis, it added many new concepts, and formed the basis of the later civil law systems that prevail in the vast majority of countries.
The body politic is a polity—such as a city, realm, or state—considered metaphorically as a physical body. Historically, the sovereign is typically portrayed as the body's head, and the analogy may also be extended to other anatomical parts, as in political readings of Aesop's fable of "The Belly and the Members". The image originates in ancient Greek philosophy, beginning in the 6th century BC, and was later extended in Roman philosophy. Following the high and late medieval revival of the Byzantine Corpus Juris Civilis in Latin Europe, the "body politic" took on a jurisprudential significance by being identified with the legal theory of the corporation, gaining salience in political thought from the 13th century on. In English law the image of the body politic developed into the theory of the king's two bodies and the Crown as corporation sole.
Lex animata is a Latin term for the law being embodied in a living entity, usually the sovereign by the grace of God. In that sense a king could be lex animata, a living, breathing law. The equivalent Greek term, used in the Byzantine Empire, is νόμος ἔμψυχος, nómos émpsychos.
