A triumvirate is a political regime ruled or dominated by three powerful individuals known as triumvirs. The arrangement can be informal. Though the three are notionally equal, this is the case in reality; the term can be used to describe a state with three different military leaders who all claim to be the sole leader. In the context of the Soviet Union and Russia, the term troika is used for "triumvirate". Another synonym is triarchy. Triumviri were special commissions of three men appointed for specific administrative tasks apart from the regular duties of Roman magistrates; the triumviri capitales, for instance, oversaw prisons and executions, along with other functions that, as Andrew Lintott notes, show them to have been "a mixture of police superintendents and justices of the peace." The capitales were first established around 290–287 BCE. They were supervised by the praetor urbanus; these triumviri, or the tresviri nocturni, may have taken some responsibility for fire control. The triumviri monetalis supervised the issuing of Roman coins.
Three-man commissions were appointed for purposes such as establishing colonies or distributing land. Triumviri mensarii served as public bankers. Another form of three-man commission was the tresviri epulones, who were in charge of organizing public feasts on holidays; this commission was created in 196 BCE by a tribunician law on behalf of the people, their number was increased to seven. The term is most used by historians to refer to the First Triumvirate of Julius Caesar, Marcus Licinius Crassus, Pompey the Great, the Second Triumvirate of Octavianus, Mark Antony, Marcus Aemilius Lepidus. In the Bible triumvirates occurred at some notable events in both the Old Testament and New Testament. In the Book of Exodus Moses, his brother Aaron and, according to some views their nephew or brother-in-law, Hur acted this way during Battle of Rephidim against the Amalekites. In the Gospels as a leading trio among the Twelve Apostles at three particular occasions during public ministry of Jesus acted Peter, son of Zebedee and his brother John.
They were the only apostles present at the Raising of Jairus' daughter, Transfiguration of Jesus and Agony in the Garden of Gethsemane. At the time of the Early Christian Church this triumvirate of the leading apostles changed as it became composed of Peter and James, brother of Jesus. One of the most notable triumvirates formed in the history of China was by the Han Dynasty statesmen Huo Guang, Jin Midi, Shangguan Jie 上官桀, following the death of Emperor Wu of Han and the installation of the child emperor Zhao. Despite the Three Excellencies—including the Chancellor, Imperial Secretary, irregularly the Grand Commandant—representing the most senior ministerial positions of state, this triumvirate was supported by the economic technocrat and Imperial Secretary Sang Hongyang, their political lackey; the acting Chancellor Tian Qianqiu was easily swayed by the decisions of the triumvirate. The Three Excellencies existed in Western Han as the Chancellor, Imperial Secretary, Grand Commandant, but the Chancellor was viewed as senior to the Imperial Secretary while the post of Grand Commandant was vacant for most of the dynasty.
After Emperor Guangwu established the Eastern Han, the Grand Commandant was made a permanent official while the Minister over the Masses replaced the Chancellor and the Minister of Works replaced the Imperial Secretary. Unlike the three high officials in Western Han when the Chancellor was senior to all, these new three senior officials had equal censorial and advisory powers; when a young or weak-minded emperor ascended to the throne, these Three Excellencies could dominate the affairs of state. There were other types of triumvirates during the Eastern Han. In Hinduism, the gods Brahma and Shiva form the triumvirate Trimurti "in which the cosmic functions of creation and destruction are personified" by those gods.." Tamil Triumvirate refers to the triumvirate of Chola and Pandya who dominated the politics of the ancient Tamil country. The title was revived a few times for three-headed political'magistratures' in post-feudal times. While French Huguenots had derisively bestowed the name Triumvirate on the alliance formed in 1561 between Catholic Francis, Duke of Guise, Anne de Montmorency, Jacques Dalbon, Seigneur de Saint Andre during the French Wars of Religion, in years the term would be used to describe other arrangements within France.
At the end of the 1700s, when the French revolutionaries turned to several Roman Magistrature names for their new institutions, the three-headed collective Head of State was named Consulat, a term in use for two-headed magistratures since Antiquity.
The Latin word imperator derives from the stem of the verb imperare, meaning'to order, to command'. It was employed as a title equivalent to commander under the Roman Republic, it became a part of the titulature of the Roman Emperors as part of their cognomen. The English word emperor derives from imperator via Old French Empereür; the Roman emperors themselves based their authority on multiple titles and positions, rather than preferring any single title. Imperator was used consistently as an element of a Roman ruler's title throughout the principate and the dominate. In Latin, the feminine form of Imperator is imperatrix; when Rome was ruled by kings, to be able to rule, the king had to be invested with the full regal authority and power. So, after the comitia curiata, held to elect the king, the king had to be conferred the imperium. In Roman Republican literature and epigraphy, an imperator was a magistrate with imperium, but mainly in the Roman Republic and during the late Republican civil wars, imperator was the honorific title assumed by certain military commanders.
After an great victory, an army's troops in the field would proclaim their commander imperator, an acclamation necessary for a general to apply to the Senate for a triumph. After being acclaimed imperator, the victorious general had a right to use the title after his name until the time of his triumph, where he would relinquish the title as well as his imperium. Since a triumph was the goal of many politically ambitious Roman commanders, Roman Republican history is full of cases where legions were bribed to call their commander imperator; the title of imperator was given in 90 BC to Lucius Julius Caesar, in 84 BC to Gnaeus Pompeius Magnus, in 60 BC to Gaius Julius Caesar, relative of the mentioned Lucius Julius Caesar, in 45 BC again to Gaius Julius Caesar, in 44 BC to Marcus Iunius Brutus, in 41 BC to Lucius Antonius. In 15 AD Germanicus was imperator during the empire of his adoptive father Tiberius. After Augustus established the Roman Empire, the title imperator was restricted to the emperor, though in the early years of the empire it would be granted to a member of his family.
As a permanent title, imperator was used as a praenomen by the Roman emperors and was taken on accession. After the reign of Tiberius, the act of being proclaimed imperator was transformed into the act of imperial accession. In fact, if a general was acclaimed by his troops as imperator, it would be tantamount to a declaration of rebellion against the ruling emperor. At first the term continued to be used in the Republican sense as a victory title but attached to the de facto monarch and head of state, rather than the actual military commander; the title followed the emperor's name along with the number of times he was acclaimed as such, for example IMP V. In time it became the title of the de facto monarch, pronounced upon their assumption; as a title imperator was translated into Greek as autokrator This was imprecise as it lost the nuances of Latin political thought contrasting imperium with other forms of public authority. This title was used in Greek-language texts for Roman emperors from the establishment of the empire.
In the east, the title continued to be used into the Byzantine period, though to a lesser, much more ceremonial, extent. In most Byzantine writings, the Greek translation "Autokrator" is preferred, but "Imperator" makes an appearance in Constantine IV's mid 7th century mosaic in the Basilica of Sant'Apollinare in Classe, on various 9th century lead seals. After the Roman empire collapsed in the West in the 5th century, Latin continued to be used as the language of learning and diplomacy for some centuries; the Roman emperors of this period were referred to as imperatores in Latin texts, while the word basileus was used in Greek. After 800, the imperator was used as a formal Latin title in succession by the Carolingian and German Holy Roman Emperors until 1806 and by the Austrian Emperors until 1918. In medieval Spain, the title imperator was used under a variety of circumstances from the ninth century onwards, but its usage peaked, as a formal and practical title, between 1086 and 1157, it was used by the Kings of León and Castile, but it found currency in the Kingdom of Navarre and was employed by the Counts of Castile and at least one Duke of Galicia.
It signalled at various points the king's equality with the Byzantine Emperor and Holy Roman Emperor, his rule by conquest or military superiority, his rule over several people groups ethnic or religious, his claim to suzerainty over the other kings of the peninsula, both Christian and Muslim. Beginning in 1077 Alfonso instituted the use of the style ego Adefonsus imperator totius Hispaniae and its use soon became regular; this title was used throughout the period 1079–81, which represents the peak of his imperial pretensions before his capture of the city of Toledo, ancient capital of the Visigoths. In 1080 he introduced the form ego Adefonsus Hispaniarum imperator, which he used again in 1090, his most elaborate imperial title was ego Adefonsus imperator totius Castelle et Toleto necnon et Nazare seu Alave. In 1721
Citizenship in ancient Rome was a privileged political and legal status afforded to free individuals with respect to laws and governance. A male Roman citizen enjoyed a wide range of privileges and protections defined in detail by the Roman state. A citizen could, under certain exceptional circumstances, be deprived of his citizenship. Roman women had a limited form of citizenship. Though held in high regard they were not allowed to stand for civil or public office; the rich might participate in public life by funding building projects or sponsoring religious ceremonies and other events. Women had the right to own property, to engage in business, to obtain a divorce, but their legal rights varied over time. Marriages were an important form of political alliance during the Republic. Client state citizens and allies of Rome could receive a limited form of Roman citizenship such as the Latin Right; such citizens could not be elected in Roman elections. Slaves lacked legal personhood. Over time, they acquired a few protections under Roman law.
Some slaves were freed by manumission for services rendered, or through a testamentary provision when their master died. Once free, they faced few barriers, beyond normal social snobbery, to participating in Roman society; the principle that a person could become a citizen by law rather than birth was enshrined in Roman mythology. Freedmen were former slaves, they were not automatically given citizenship and lacked some privileges such as running for executive magistracies. The children of freedmen and women were born as free citizens. Ius suffragiorum: The right to vote in the Roman assemblies. Ius honorum: The right to stand for civil or public office. Ius commercii: The right to make legal contracts and to hold property as a Roman citizen. Ius gentium: The legal recognition, developed in the 3rd century BC, of the growing international scope of Roman affairs, the need for Roman law to deal with situations between Roman citizens and foreign persons; the ius gentium was therefore a Roman legal codification of the accepted international law of the time, was based on the developed commercial law of the Greek city-states and of other maritime powers.
The rights afforded by the ius gentium were considered to be held by all persons. Ius conubii: The right to have a lawful marriage with a Roman citizen according to Roman principles, to have the legal rights of the paterfamilias over the family, for the children of any such marriage to be counted as Roman citizens. Ius migrationis: The right to preserve one's level of citizenship upon relocation to a polis of comparable status. For example, members of the cives Romani maintained their full civitas when they migrated to a Roman colony with full rights under the law: a colonia civium Romanorum. Latins had this right, maintained their ius Latii if they relocated to a different Latin state or Latin colony; this right did not preserve one's level of citizenship should one relocate to a colony of lesser legal status. The right of immunity from some taxes and other legal obligations local rules and regulations; the right to sue in the right to be sued. The right to have a legal trial; the right to appeal the lower court decisions.
Following the early 2nd-century BC Porcian Laws, a Roman citizen could not be tortured or whipped and could commute sentences of death to voluntary exile, unless he was found guilty of treason. If accused of treason, a Roman citizen had the right to be tried in Rome, if sentenced to death, no Roman citizen could be sentenced to die on the cross. Roman citizenship was required in order to enlist in the Roman legions, but this was sometimes ignored. Citizen soldiers could be beaten by the centurions and senior officers for reasons related to discipline. Non-citizens gained citizenship through service; the legal classes varied over time, however the following classes of legal status existed at various times within the Roman state: The cives Romani were full Roman citizens, who enjoyed full legal protection under Roman law. Cives Romani were sub-divided into two classes: The non optimo iure who held the ius commercii and ius conubii The optimo iure, who held these rights as well as the ius suffragiorum and ius honorum.
The Latini were a class of citizens who held the Latin Right, or the rights of ius commercii and ius migrationis, but not the ius conubii. The term Latini referred to the Latins, citizens of the Latin League who came under Roman control at the close of the Latin War, but became a legal description rather than a national or ethnic one. Freedmen slaves, those of the cives Romani convicted of crimes, or citizens settling Latin colonies could be given this status under the law. Socii or foederati were citizens of states which had treaty obligations with Rome, under which certain legal rights of the state's citizens under Roman law were exchanged for agreed levels of military service, i.e. the Roman magistrates had the right to levy soldiers for the Roman legions from those states. However, foederat
Caesar is a title of imperial character. It derives from the cognomen of the Roman dictator; the change from being a familial name to a title adopted by the Roman Emperors can be dated to about AD 68/69, the so-called "Year of the Four Emperors". For political and personal reasons, Octavian chose to emphasize his relationship with Julius Caesar by styling himself "Imperator Caesar", without any of the other elements of his full name, his successor as emperor, his stepson Tiberius bore the name as a matter of course. The precedent was set: the Emperor designated his successor by adopting him and giving him the name "Caesar"; the fourth Emperor, was the first to assume the name "Caesar" upon accession, without having been adopted by the previous emperor. Claudius in turn adopted his stepson and grand-nephew Lucius Domitius Ahenobarbus, giving him the name "Caesar" in the traditional way; the first emperor to assume the position and the name without any real claim to either was the usurper Servius Sulpicius Galba, who took the imperial throne under the name "Servius Galba Imperator Caesar" following the death of the last of the Julio-Claudians, Nero, in 68.
Galba helped solidify "Caesar" as the title of the designated heir by giving it to his own adopted heir, Lucius Calpurnius Piso Frugi Licinianus. Galba's reign did not last long and he was soon deposed by Marcus Otho. Otho did not at first use the title "Caesar" and used the title "Nero" as emperor, but adopted the title "Caesar" as well. Otho was defeated by Aulus Vitellius, who acceded with the name "Aulus Vitellius Germanicus Imperator Augustus". Vitellius did not adopt the cognomen "Caesar" as part of his name and may have intended to replace it with "Germanicus". Caesar had become such an integral part of the imperial dignity that its place was restored by Titus Flavius Vespasianus, whose defeat of Vitellius in 69 put an end to the period of instability and began the Flavian dynasty. Vespasian's son, Titus Flavius Vespasianus became "Titus Flavius Caesar Vespasianus". By this point the status of "Caesar" had been regularised into that of a title given to the Emperor-designate and retained by him upon accession to the throne.
After some variation among the earliest emperors, the style of the Emperor-designate on coins was Nobilissimus Caesar "Most Noble Caesar", though Caesar on its own was used. The popularity of using the title Caesar to designate heirs-apparent increased throughout the third century. Many of the soldier emperors during the Crisis of the Third Century attempted to strengthen their legitimacy by naming heirs, including Maximinus Thrax, Philip the Arab, Trebonianus Gallus and Gallienus; some of these were promoted to the rank of Augustus within their father's lifetime, for example Philippus II. The same title would be used in the Gallic Empire, which operated autonomously from the rest of the Roman Empire from 260 to 274, with the final Gallic emperor Tetricus I appointing his heir Tetricus II Caesar and his consular colleague for 274. Despite the best efforts of these emperors, the granting of this title does not seem to have made succession in this chaotic period any more stable. All Caesars would be killed before or alongside their fathers, or at best outlive them for a matter of months, as in the case of Hostilian.
The sole Caesar to obtain the rank of Augustus and rule for some time in his own right was Gordian III, he was controlled by his court. On 1 March 293, Gaius Aurelius Valerius Diocletianus established the Tetrarchy, a system of rule by two senior Emperors and two junior sub-Emperors; the two coequal senior emperors were styled identically to previous Emperors, as Imperator Caesar NN. Pius Felix Invictus Augustus and were called the Augusti, while the two junior sub-Emperors were styled identically to previous Emperors-designate, as Nobilissimus Caesar; the junior sub-Emperors retained the title "Caesar" upon accession to the senior position. The Tetrarchy was abandoned as a system in favour of two equal, territorial emperors, the previous system of Emperors and Emperors-designate was restored, both in the Latin-speaking West and the Greek-speaking East; the title of Caesar remained in use throughout the Constantinian period, with both Constantine I and his co-emperor and rival Licinius utilising it to mark their heirs.
In the case of Constantine, this meant that by the time he died, he had four Caesars: Constantius II, Constantine II, Constans and his nephew Dalmatius, with his eldest son Crispus having been executed in mysterious circumstances earlier in his reign. In the event, Constantine would be su
The cursus honorum was the sequential order of public offices held by aspiring politicians in both the Roman Republic and the early Roman Empire. It was designed for men of senatorial rank; the cursus honorum comprised a mixture of political administration posts. Each office had a minimum age for election. There were minimum intervals between holding successive offices and laws forbade repeating an office; these rules were flagrantly ignored in the course of the last century of the Republic. For example, Gaius Marius held consulships for five years in a row between 104 BC and 100 BC, he was consul seven times in all serving in 107 and 86. Presented as opportunities for public service, the offices became mere opportunities for self-aggrandizement; the reforms of Sulla required a ten-year interval before holding the same office again for another term. To have held each office at the youngest possible age was considered a great political success. For instance, to miss out on a praetorship at 39 meant that one could not become consul at 42.
Cicero expressed extreme pride not only in being a novus homo who became consul though none of his ancestors had served as a consul, but in having become consul "in his year". The cursus honorum began with ten years of military duty in the Roman cavalry or in the staff of a general, a relative or a friend of the family; the ten years of service were intended to be mandatory in order to qualify for political office, but in practice, the rule was not always rigidly applied. A more prestigious position was that of a military tribune. In the early Roman Republic, 24 men at the age of around 20 were elected by the Tribal Assembly to serve as a commander in the legions, with six tribunes to each and command rotating among them. Tribunes could be appointed by the consuls or by military commanders in the field as necessary. After the reforms of Gaius Marius in 107 BC, the six tribunes acted as staff officers for the legionary legatus and were appointed tasks and command of units of troops whenever the need arose.
The subsequent steps of the cursus honorum were achieved by direct election every year. The first official post was that of quaestor. Candidates had to be at least 30 years old. However, men of patrician rank could subtract two years from this and other minimum age requirements. Twenty quaestors served in the financial administration at Rome or as second-in-command to a governor in the provinces, they could serve as the paymaster for a legion. A young man who obtained this job was expected to become a important official. An additional task of all quaestors was the supervision of public games; as a quaestor, an official was allowed to wear the toga praetexta, but was not escorted by lictors, nor did he possess imperium. At 36 years of age, proquaestor could stand for election to one of the aedile positions. Of these aediles, two were plebeian and two were patrician, with the patrician aediles called Curule Aediles; the plebeian aediles were elected by the Plebeian Council and the curule aediles were either elected by the Tribal Assembly or appointed by the reigning consul.
The aediles had administrative responsibilities in Rome. They had to take care of the temples, organize games, be responsible for the maintenance of the public buildings in Rome. Moreover, they took charge of Rome's food supplies; the Aedile was the supervisor of public works. He oversaw the public works and markets. Therefore, the Aediles would have been in some cooperation with the current Censors, who had similar or related duties, they oversaw the organization of festivals and games, which made this a sought-after office for a career minded politician of the late republic, as it was a good means of gaining popularity by staging spectacles. Curule Aediles were added at a date in the 4th century BC, their duties do not differ from plebeian aediles. However, unlike plebeian aediles, curule aediles were allowed certain symbols of rank—the sella curulis or'curule chair,' for example—and only patricians could stand for election to curule aedile; this changed, both Plebeians and Patricians could stand for Curule Aedileship.
The elections for Curule Aedile were at first alternated between Patricians and Plebeians, until late in the 2nd century BC, when the practice was abandoned and both classes became free to run during all years. While part of the cursus honorum, this step was not required to hold future offices. Though the office was held after the quaestorship and before the praetorship, there are some cases with former praetors serving as aediles. After serving either as quaestor or as aedile, a man of 39 years could run for praetor; the number of praetors elected varied through history increasing with time. During the republic, six or eight were elected each year to serve judicial functions throughout Rome and other governmental responsibilities. In the absence of the consuls, a praetor would be given command of the garrison in Italy. A praetor could exercise the functions of the consuls throughout Rome, but their main function was that of a judge, they would preside over trials involving criminal acts, grant court orders and validate "illegal" acts as acts of administering justice.
A praetor was escorted by six lictors, wielded imperium. After a term as praetor, the magistrate would serve as a provincial governor with the title of propraetor
The Roman Kingdom referred to as the Roman monarchy, or the regal period of ancient Rome, was the earliest period of Roman history, when the city and its territory were ruled by kings. Little is certain about the kingdom's history, as no records and few inscriptions from the time of the kings survive, the accounts of this period written during the Republic and Empire are thought to be based on oral tradition. According to these legends, the Roman Kingdom began with the city's founding circa 753 BC, with settlements around the Palatine Hill along the river Tiber in central Italy, ended with the overthrow of the kings and the establishment of the Republic circa 509 BC; the site of the founding of the Roman Kingdom had a ford where one could cross the river Tiber in central Italy. The Palatine Hill and hills surrounding it provided defensible positions in the wide fertile plain surrounding them; each of these features contributed to the success of the city. The traditional version of Roman history, which has come down to us principally through Livy and Dionysius of Halicarnassus, recounts that a series of seven kings ruled the settlement in Rome's first centuries.
The traditional chronology, as codified by Varro, allows 243 years for their combined reigns, an average of 35 years. Since the work of Barthold Georg Niebuhr, modern scholarship has discounted this schema; the Gauls destroyed many of Rome's historical records when they sacked the city after the Battle of the Allia in 390 BC, what remained fell prey to time or to theft. With no contemporary records of the kingdom surviving, all accounts of the Roman kings must be questioned; the kings, excluding Romulus, who according to legend held office by virtue of being the city's founder, were all elected by the people of Rome to serve for life, with none of the kings relying on military force to gain or keep the throne. The insignia of the kings of Rome were twelve lictors wielding the fasces bearing axes, the right to sit upon a Curule chair, the purple Toga Picta, red shoes, a white diadem around the head. Of all these insignia, the most important was the purple toga; the king was invested with supreme military and judicial authority through the use of imperium, formally granted to the king by the Comitia Curiata with the passing of the Lex curiata de imperio at the beginning of each king's reign.
The imperium of the king was held for life and protected him from being brought to trial for his actions. As being the sole owner of imperium in Rome at the time, the king possessed ultimate executive power and unchecked military authority as the commander-in-chief of all Rome's legions; the laws that kept citizens safe from magistrates' misuse of imperium did not exist during the monarchical period. Another power of the king was the power to either nominate all officials to offices; the king would appoint a tribunus celerum to serve as both the tribune of Ramnes tribe in Rome and as the commander of the king's personal bodyguard, the Celeres. The king was required to appoint the tribune upon entering office and the tribune left office upon the king's death; the tribune was second in rank to the king and possessed the power to convene the Curiate Assembly and lay legislation before it. Another officer appointed by the king was the praefectus urbi; when the king was absent from the city, the prefect held all of the king's powers and abilities to the point of being bestowed with imperium while inside the city.
The king received the right to be the only person to appoint patricians to the Senate. What is known for certain is that the king alone possessed the right to the auspice on behalf of Rome as its chief augur, no public business could be performed without the will of the gods made known through auspices; the people knew the king as a mediator between them and the gods and thus viewed the king with religious awe. This made the king the head of its chief executive. Having the power to control the Roman calendar, he conducted all religious ceremonies and appointed lower religious offices and officers, it is said that Romulus himself instituted the augurs and was believed to have been the best augur of all. King Numa Pompilius instituted the pontiffs and through them developed the foundations of the religious dogma of Rome. Under the kings, the Senate and Curiate Assembly had little power and authority, they could only be called together by the king and could only discuss the matters the king laid before them.
While the Curiate Assembly did have the power to pass laws, submitted by the king, the Senate was an honorary council. It by no means could prevent him from acting; the only thing that the king could not do without the approval of the Senate and Curiate Assembly was to declare war against a foreign nation. The king's imperium both granted him military powers and qualified him to pronounce legal judgment in all cases as the chief justice of Rome. Though he could assign pontiffs to act as minor judges in some cases, he had supreme authority in all cases brought before him, both civil and criminal; this made the king supreme in times of both peace. While some writers believed there was no appeal from the king's decisions, others believed that a proposal for appeal could
Constitution of the Late Roman Empire
The constitution of the late Roman Empire was an unwritten set of guidelines and principles passed down through precedent, which defined the manner in which the late Roman Empire was governed. As a matter of historical convention, the late Roman Empire emerged from the Roman Principate, with the accession of Diocletian in AD 284, his reign marking the beginning of the Dominate; the constitution of the Dominate recognized monarchy as the true source of power, thus ended the fiction of dyarchy, in which emperor and Senate governed the empire together. Diocletian's reforms to the imperial government ended the ruse that the old republican magistracies were anything more than municipal officials with powers beyond Rome itself. By the late Empire, the consuls had no real duties beyond that of presiding at Senate meetings and the duties of the lesser magistrates were just the organisation of various games. Most other magistracies disappeared. Diocletian attempted to reform the imperial system itself into a structure in which four emperors, consisting of two Augusti and two Caesares, each governed one fourth of the Empire.
Known as the Tetrarchy, this constitutional structure, failed to outlast Diocletian, who lived to see the collapse of his system and the civil wars that followed in his retirement after abdication in AD 305. He enacted major administrative reforms to the Empire, his division of the Empire into east and west, with each half under the command of a separate emperor, remained with brief interruptions of political unity. Although it remained the sole capital until Constantinople was elevated to that status in 359, the city of Rome ceased to the seat of the imperial government: it was by the Urban Prefect. A vicar of the Prefect of Italy headed the imperial administration of Italy south of the Apennines and the Islands; the Senate and executive magistrates continued to function as Diocletian's constitution had specified. Diocletian's civil and military divisions of the empire remained in effect with little change though Upper Egypt from the mid-fifth was governed by a general, the dux, who exercised civilian authority over the population.
Emperors Constantine would modify Diocletian's constitution by changing the roles of officials somewhat but not the administrative framework. It was not until Justinian I 527-565 that major changes that saw the near abolition of the regional tier of officials, severe weakening of the Treasury and Crown Estates. Under Diocletian's new constitution, power was shared between two emperors called Augusti; the establishment of two co-equal Augusti marked a rebirth of the old republican principle of collegiality, as all laws and appointments that came from one of the Augusti, were to be recognized as coming from both conjointly. One Augustus was to rule the western half of the Empire, the other Augustus was to rule the eastern half of the Empire. Diocletian made Maximian his co-Augustus, gave him the Western Empire, while Diocletian took the Eastern Empire. Diocletian made Nicomedia his capital, Maximian made Milan his capital. To make the two halves symbolically appear to be one, Diocletian called his territory patres Orientis, while Maximian called his territory patres Occidentis.
The Augusti were distinct from the old Princeps, because under the Principate, the Princeps took the place of the old republican magistrates. When a Princeps issued a decree, that decree was only valid so long as that Princeps was Emperor, whereas in contrast, under the Republic, any decree issued by a magistrate was only good so long as that magistrate was in office. Under the Republic and the Principate, only the Senate and legislative assemblies were continuous institutions, thus only they could pass laws that remained in effect indefinitely. Under Diocletian's new Dominate, the Augusti took the place of the Senate and the assemblies, thus any decree of an Augustus remained in force after that particular emperor left office; such an act could only be invalidated by a future Emperor. The logical extension of this concept meant that neither a magistrate, the assemblies, nor the senate, could restrain the Emperor; the old republican magistrates, as well as the Princeps, both had legal status.
Under the Republic, the state gave the magistrates the authorization to hold their office, while under the Principate, the state gave the Princeps the legal authorization to be emperor. Any Augusti, in contrast, did not need authorization from the state to be emperor, because the Augusti became the state; the higher authority of the Augusti was illustrated by their robes and the imperial diadem, as well as the elaborate ceremony required of anyone who approached them. Unlike the old Princeps, the Augusti were viewed as being more than mortal, illustrated by the honors that they received; these honors had, in the past, been reserved only for the Gods. While emperors had received such honors in the past, they only received these honors after their death, yet, the Augusti could receive such honors while they were still alive. In 293, Diocletian and Maximian appointed two Caesares, which resulted in an arrangement known as the "Tetrarchy"; the Caesares were subordinate to their Augusti, the only authority that they had was that, given to them by their Augusti.
Their status was so inferior to the Augusti. The powers that were delegated to them included the right to hear appeals, a set of provinces were assigned to them so that they could supervise the governors of those provinces; the reason why Diocle
