The Roman emperor was the ruler and monarchical head of state of the Roman Empire , starting with the granting of the title augustus to Octavian in 27 BC. The term emperor is a modern convention, and did not exist as such during the Empire. When a given Roman is described as becoming emperor in English, it generally reflects his accession as augustus , and later as basileus . Another title used was imperator , originally a military honorific, and caesar , originally a cognomen . Early emperors also used the title princeps ('first one') alongside other Republican titles, notably consul and pontifex maximus .
171-537: Lucius Septimius Severus ( Latin: [ˈɫuːkiʊs sɛpˈtɪmiʊs sɛˈweːrʊs] ; 11 April 145 – 4 February 211) was Roman emperor from 193 to 211. He was born in Leptis Magna (present-day Al-Khums , Libya) in the Roman province of Africa . As a young man he advanced through the customary succession of offices under the reigns of Marcus Aurelius and Commodus . Severus was the final contender to seize power after
342-601: A vigintivir in Rome, overseeing road maintenance in or near the city, and he may have appeared in court as an advocate. At the time of Marcus Aurelius, he was the State Attorney ( Advocatus fisci ). However, he omitted the military tribunate from the cursus honorum and had to delay his quaestorship until he had reached the required minimum age of 25. To make matters worse, the Antonine Plague swept through
513-577: A Pragmatic sanction which maintained most of the organization of Diocletian . The "Prefecture of Italy" thus survived, and was reestablished under Roman control in the course of Justinian 's Gothic War . As a result of the Lombard invasion in 568, the Byzantines lost most of Italy, except the territories of the Exarchate of Ravenna – a corridor from Venice to Lazio via Perugia – and footholds in
684-608: A theocracy . According to George Ostrogorsky , "the absolute power of the Roman emperor was further increased with the advent of Christian ideas". This became more evident after the Muslim conquests of the 7th century, which gave Byzantine imperialism a new sense of purpose. The emperor was the subject of a series of rites and ceremonies, including a formal coronation performed by the Patriarch of Constantinople . The Byzantine state
855-519: A 50-year period that almost saw the end of the Roman Empire. The last vestiges of Republicanism were lost in the ensuing anarchy. In 238, the Senate attempted to regain power by proclaiming Pupienus and Balbinus as their own emperors (the first time since Nerva ). They managed to usurp power from Maximinus Thrax , but they were killed within two months. With the rise of the "soldier emperors",
1026-546: A court title bestowed to prominent figures of the government, and lost even more relevance after the creation of the title sebastokrator by Alexios I Komnenos . Despite this, its regular use by earlier emperors led to the name becoming synonym with "emperor" in certain regions. Several countries use Caesar as the origin of their word for "emperor", like Kaiser in Germany and Tsar in Bulgaria and Russia . After
1197-544: A family name ( nomen ), styling himself as Imp. Caesar instead of Imp. Julius Caesar . However, the nomen was still inherited by women (such as Julia the Younger ) and appear in some inscriptions. After the death of Caligula , Augustus' great-grandson, his uncle Claudius was proclaimed emperor. He was not an official member of the Julia gens , but he was the grandson of Octavia , Augustus' sister, and thus still part of
1368-485: A military central reserve with the capability to be sent anywhere. At the beginning of Severus' reign, Trajan 's policy toward the Christians was still in force. That is, Christians were only to be punished if they refused to worship the emperor and the gods, but they were not to be sought out. Therefore, persecution was inconsistent, local and sporadic. Faced with internal dissidence and external threats, Severus felt
1539-534: A more ambitious campaign. The following year he led another, more successful campaign against the Parthian Empire , reportedly in retaliation for the support it had given to Pescennius Niger . His legions sacked the Parthian royal city of Ctesiphon and he annexed the northern half of Mesopotamia to the empire; Severus took the title Parthicus Maximus , following the example of Trajan . However, he
1710-473: A new caesar . Each pair ruled over a half of the Empire, which led to the creation of a Western and Eastern Roman Empire , a division that eventually became permanent. This division had already a precedent in the joint rule of Valerian / Gallienus and Carus / Carinus . Diocletian justified his rule not by military power, but by claiming divine right . He imitated Oriental divine kingship and encouraged
1881-505: A persecutor. However, the Christian apologist Tertullian stated that Severus was well disposed towards Christians, employed a Christian as his personal physician and had personally intervened to save several high-born Christians known to him from the mob. Some scholars think that Eusebius' description of Severus as a persecutor likely derives merely from the fact that numerous persecutions occurred during his reign, including those known in

#17327649800482052-541: A regime in which the notion of legitimacy is as absent as that of the Augustan principate". Imperial propaganda was often used to legitimize or de-legitimize certain emperors. The Chronicon Paschale , for example, describes Licinius as having been killed like "those who had briefly been usurpers before him". In reality, Licinius was the legitimate emperor of the West (having been appointed by Galerius ), while Constantine
2223-423: A relatively destructive effect on the centre of power. Plautianus' daughter Fulvia Plautilla was married to Severus' son Caracalla. Plautianus' excessive power came to an end in 204, when he was denounced by the emperor's dying brother. In January 205 Julia Domna and Caracalla accused Plautianus of plotting to kill him and Severus. The powerful prefect was executed while he was trying to defend his case in front of
2394-516: A senior military appointment. Following the end of this term, Septimius Severus returned to Rome, taking up office as tribune of the plebs , a senior legislative position, with the distinction of being the candidatus of the emperor. About 175, Septimius Severus, in his early thirties at the time, contracted his first marriage, to Paccia Marciana , a woman from Leptis Magna. He probably met her during his tenure as legate under his uncle. Marciana's name suggests Punic or Libyan origin, but nothing else
2565-645: A short stay in Rome, Severus moved north to meet him. On 19 February 197 at the Battle of Lugdunum , with an army of about 75,000 men, mostly composed of Pannonian , Moesian and Dacian legions and a large number of auxiliaries, Severus defeated and killed Clodius Albinus, securing his full control over the empire. Upon returning to Rome, Septimus had 29 senators executed for treason over their support of Albinus, despite having previously taken an oath promising not to put any senators to death (a customary oath for emperors). In early 197 Severus left Rome and sailed to
2736-574: A time decisive, securing Nisibis and Singara for the empire and establishing a status quo of Roman dominance in the region until 251. His policy of an expanded and better-rewarded army was criticised by his contemporaries Cassius Dio and Herodianus : in particular, they pointed out the increasing burden, in the form of taxes and services, the civilian population had to bear to maintain the new and better-paid army. The large and ongoing increase in military expenditure caused problems for all of his successors. To maintain his enlarged military, he debased

Notes: Bibliography: Roman emperor The legitimacy of an emperor's rule depended on his control of the Roman army and recognition by the Senate ; an emperor would normally be proclaimed by his troops, or by the Senate, or both.

On his death, Severus was deified by the Senate and succeeded by his sons, Caracalla and Geta , who were advised by his wife Julia Domna . Severus was buried in the Mausoleum of Hadrian in Rome. By the close of his reign the Roman Empire reached an extent of over 5 million square kilometres, which scholars like David L. Kennedy , Lukas De Blois, and Derrick Riley state expanded
3249-561: Is known as the Dominate , derived from the title dominus ("lord") adopted by Diocletian . During his rule, the emperor became an absolute ruler and the regime became even more monarchical. The emperors adopted the diadem crown as their supreme symbol of power, abandoning the subtleties of the early Empire. Beginning in the late 2nd century, the Empire began to suffer a series of political and economic crises, partially because it had overexpanded so much. The Pax Romana ("Roman peace")

The unreliable Historia Augusta claims that Marciana and Severus had two daughters, but no other attestation of them has survived. It appears that the marriage produced no surviving children, despite lasting for more than ten years. Marciana died of natural causes around 186. Septimius Severus, now in his forties, childless and eager to remarry, began enquiring into

This Lex sometimes related to the Lex regia ("royal law") mentioned in the Corpus Juris Civilis of Eastern emperor Justinian I (r. 527–565), who cites the early 3rd-century writer Ulpian . This was probably a later construct, as its very name, which derives from rex ("king"), would have been utterly rejected in

His murder was followed by the accession of Septimius Severus , the victor of the Year of the Five Emperors . It was during his reign that the role of the army grew even more, and the emperors' power increasingly depended on it. The murder of his last relative, Severus Alexander , led to the Crisis of the Third Century (235–285),

The line of Eastern emperors continued uninterrupted until the sack of Constantinople and the establishment of the Latin Empire in 1204. This led to the creation of three lines of emperors in exile:

Western emperors such as Magnentius , Eugenius and Magnus Maximus are sometimes called usurpers, but Romulus Augustulus is traditionally regarded as the last Western emperor, despite never receiving the recognition of the Eastern emperor Zeno . The period after the Principate

In 202, he campaigned in Africa and Mauretania against the Garamantes , capturing their capital Garama and expanding the Limes Tripolitanus along the southern desert frontier of the empire. With his second wife, Julia Domna , Severus had two sons; the elder, Caracalla , was proclaimed Augustus , or co-emperor, in 198, and the younger, Geta , in 209. Severus travelled to Britain in 208, strengthening Hadrian's Wall and reoccupying

In 209 he invaded Caledonia (modern Scotland ) with an army of 50,000 men but his ambitions were cut short when he died of an infectious disease in early 211 at Eboracum (modern York ). His sons, advised by Julia Domna, succeeded him, thus founding the Severan dynasty . It was the last dynasty of the Roman Empire before the Crisis of the Third Century .

He captured several settlements such as Cydamus , Gholaia, Garbia and their capital Garama —over 600 kilometres (370 mi) south of Leptis Magna . The province of Numidia was also enlarged: the empire annexed the settlements of Vescera , Castellum Dimmidi , Gemellae , Thabudeos and Thubunae .

Upon his accession he decreased the silver purity of the denarius from 81.5% to 78.5%, although the silver weight actually increased, rising from 2.40 grams to 2.46 grams. Nevertheless, the following year he debased the denarius again because of rising military expenditures.

The weakest point of the Augustan institution was its lack of a clear succession system. Formally announcing a successor would have revealed Augustus as a monarch, so he and subsequent emperors opted to adopt their best candidates as their sons and heirs. Primogeniture
12654-704: The adoptive son of the long-deceased Marcus Aurelius , hence why he named Caracalla after him. Later Eastern imperial dynasties, such as the Doukai and Palaiologoi , claimed descent from Constantine the Great . What turns a "usurper" into a "legitimate" emperor is typically that they managed to gain the recognition of a more senior, legitimate, emperor, or that they managed to defeat a more senior, legitimate emperor and seize power. Modern historiography has not yet defined clear legitimacy criteria for emperors, resulting in some emperors being included or excluded from different lists. The year 193 has traditionally been called
12825-413: The advice of Quintus Aemilius Laetus , prefect of the Praetorian Guard , emperor Commodus appointed Severus as governor of Pannonia Superior . At around this time he is described by the classicist Kyle Harper as being "a middling senator of modest physical stature and unexceptional accomplishment". Commodus was assassinated the following year. Pertinax was acclaimed emperor, but he was then killed by
12996-474: The authority based on prestige. The honorific was awarded as both a name and a title to Octavian in 27 BC and was inherited by all subsequent emperors, who placed it after their personal names. The only emperor to not immediately assume it was Vitellius , although he did use it after his recognition by the Senate. Later emperors ruled alongside one or several junior augusti who held de jure (but not de facto ) equal constitutional power. Despite its use as
13167-454: The babe in the womb of the mother, if it be male; let it nevertheless not escape sheer destruction." Severus' campaign was cut short when he fell ill. He withdrew to Eboracum (York) and died there in 211. Although his son Caracalla continued campaigning the following year, he soon settled for peace. The Romans never campaigned deep into Caledonia again. Shortly after this, the frontier was permanently withdrawn south to Hadrian's Wall. Severus
13338-493: The capital in 166. With his career at a halt, Severus decided to temporarily return to Leptis, where the climate was healthier. According to the Historia Augusta , a usually unreliable source, he was prosecuted for adultery during this time but the case was ultimately dismissed. At the end of 169, Severus was of the required age to become a quaestor and journeyed back to Rome. On 5 December, he took office and
13509-476: The city and Senate of Rome began to lose importance. Maximinus and Carus , for example, did not even set foot on the city. Carus' successors Carinus and Numerian , the last of the Crisis emperors, did not bother to assume the tribunicia potestas either. After reuniting the Roman Empire in 285, Diocletian began a series of reforms to restore stability. Reaching back to the oldest traditions of job-sharing in
13680-588: The context of the transition from Republic to Principate , Italy swore allegiance to Octavian Augustus and was then organized in eleven regions from the Alps to the Ionian Sea with more than two centuries of stability afterward. Several emperors made notable accomplishments in this period: Claudius incorporated Britain into the Roman Empire, Vespasian subjugated the Great Revolt of Judea and reformed
13851-400: The continuance of the Republic. The title had already been used by Pompey and Julius Caesar , among others. It was a purely honorific title with no attached duties or powers, hence why it was never used in official titulature. The title was the most preferred by Augustus as its use implies only "primacy" (is in the " first among equals "), as opposed to dominus , which implies dominance. It
14022-549: The creation of a worship cult . Augustus became pontifex maximus (the chief priest of the College of Pontiffs ) in 12 BC, after the death of the former triumvir Lepidus . Emperors from the reign of Gratian (r. 375–383) onward used the style pontifex inclytus ("honorable pontiff"). The title of pontifex maximus was eventually adopted by the bishops of Rome during the Renaissance . The last known emperors to use
14193-642: The current region of Calabria ); later the term was extended by Romans to include the Italian Peninsula up to the Rubicon , a river located between Northern and Central Italy . In 49 BC, with the Lex Roscia , Julius Caesar gave Roman citizenship to the people of the Cisalpine Gaul ; while in 42 BC the hitherto existing province was abolished, thus extending Italy to the north up to
14364-462: The death of the emperor Pertinax in 193 during the Year of the Five Emperors . After deposing and killing the incumbent emperor Didius Julianus , Severus fought his rival claimants, the Roman generals Pescennius Niger and Clodius Albinus . Niger was defeated in 194 at the Battle of Issus in Cilicia . Later that year Severus waged a short punitive campaign beyond the eastern frontier, annexing
14535-436: The decline of the city of Rome (which was sacked in 410 for the first time in almost eight centuries). The name Italia covered an area whose borders evolved over time. According to Strabo 's Geographica , before the expansion of the Roman Republic , the name was used by Greeks to indicate the land between the strait of Messina and the line connecting the gulf of Salerno and gulf of Taranto (corresponding roughly to
14706-708: The east. He embarked at Brundisium and probably landed at the port of Aegeae in Cilicia , travelling on to Syria by land. He immediately gathered his army and crossed the Euphrates . Abgar IX , titular King of Osroene but essentially only the ruler of Edessa since the annexation of his kingdom as a Roman province, handed over his children as hostages and assisted Severus' expedition by providing archers. King Khosrov I of Armenia also sent hostages, money and gifts. Severus travelled on to Nisibis , which his general Julius Laetus had prevented from falling into Parthian hands. Afterwards Severus returned to Syria to plan
14877-598: The emperor Antoninus Pius r. 138–161 . His mother's ancestors had moved from Italy to North Africa; they belonged to the gens Fulvia , an Italian patrician family that originated in Tusculum . Septimius Severus had two siblings: an elder brother, Publius Septimius Geta ; and a younger sister, Septimia Octavilla. Severus' maternal cousin was the praetorian prefect and consul Gaius Fulvius Plautianus . Septimius Severus grew up in Leptis Magna. He spoke
15048-617: The emperor derived from an extraordinary concentration of individual powers and offices that were extant in the Republic and developed under Augustus and later rulers, rather than from a new political office. Under the Republic, these powers would have been split between several people, who would each exercise them with the assistance of a colleague and for a specific period of time. Augustus held them all at once by himself, and with no time limits; even those that nominally had time limits were automatically renewed whenever they lapsed. The Republican offices endured and emperors were regularly elected to
15219-403: The empire to its greatest physical extent. Edward Gibbon famously levelled a harsh indictment of Septimius Severus as a principal agent in the empire's decline. "The contemporaries of Severus, in the enjoyment of the peace and glory of his reign, forgave the cruelties by which it had been introduced. Posterity, who experienced the fatal effects of his maxims and example, justly considered him as
15390-586: The end of the Social War in 87 BC, Rome had allowed its fellow Italian allies full rights in Roman society and granted Roman citizenship to all fellow Italic peoples . After having been for centuries the heart of the Roman Empire , from the 3rd century the government and the cultural center began to move eastward: first the Edict of Caracalla in 212 AD, extended Roman citizenship to all free men within
15561-539: The end of the 2nd century BC and the 1st century BC was turbulent , beginning with the Servile Wars , continuing with the opposition of aristocratic élite to populist reformers and leading to a Social War in the middle of Italy. However, Roman citizenship was recognized to the rest of the Italians by the end of the conflict and then extended to Cisalpine Gaul when Julius Caesar became Roman dictator . In
15732-413: The end of the Empire. In the West, the title was also used by Charlemagne and the subsequent Holy Roman Emperors as part of the formula Imperator Augustus . Both Eastern and Western rulers also used the style semper augustus ("forever augustus"). The word princeps , meaning "first", was a republican term used to denote the leading member of the Senate, and it was used by the early emperors to emphasize
15903-415: The end of the fourth century by eight consulares ( Venetiae et Histriae , Aemiliae , Liguriae , Flaminiae et Piceni annonarii , Tusciae et Umbriae , Piceni suburbicarii , Campaniae , and Siciliae ), two correctores ( Apuliae et Calabriae and Lucaniae et Bruttiorum ) and seven praesides ( Alpium Cottiarum , Rhaetia Prima and Secunda , Samnii , Valeriae , Sardiniae , and Corsicae ). In
16074-498: The failure of the Tetrarchy. This practice had first been applied by Septimius Severus , who proclaimed his 10-year-old son Caracalla as augustus . He was followed by Macrinus , who did the same with his 9-year-old son Diadumenian , and several other emperors during the Crisis. This became even more common from the 4th century onwards. Gratian was proclaimed emperor at the age of 8, and his co-ruler and successor Valentinian II
16245-500: The family. Following the suicide of Nero, the last descendant of Caesar, the new emperor Galba adopted the name of Servius Galba Caesar Augustus , thus making it part of the imperial title. Five days before his murder he adopted Piso Licinianus as his son and heir, renaming him as Servius Sulpicius Galba Caesar . After this Caesar came to denote the heir apparent, who would add the name to his own as heir and retain it upon accession as augustus . The only emperor not to assume it
16416-597: The fifth century, with the Emperors controlled by their barbarian generals, the Western Imperial government maintained weak control over Italy itself, whose coasts were periodically under attack. In 476, with the abdication of Romulus Augustulus , the Western Roman Empire had formally fallen unless one considers Julius Nepos , the legitimate emperor recognized by Constantinople as the last. He
16587-471: The financial system, Trajan conquered Dacia and defeated Parthia , and Marcus Aurelius epitomized the ideal of the philosopher king . During these centuries of imperial stability , Italy was referred to as rectrix mundi ("governor of the world") and omnium terrarum parens ("parent of all lands"). The Crisis of the Third Century hit Italy particularly hard, but the Roman empire managed to survive and reconquer breakaway regions. In 286 AD,
16758-412: The first emperor, whereas Julius Caesar is considered the last dictator of the Roman Republic , a view that is shared by the Roman writers Plutarch , Tacitus , and Cassius Dio . Conversely, the majority of Roman writers, including Pliny the Younger , Suetonius and Appian , as well as most of the ordinary people of the Empire, thought of Julius Caesar as the first emperor. Caesar did indeed rule
16929-778: The grandmother of the future emperors Elagabalus and Alexander Severus . Bassianus accepted Severus' marriage proposal in early 187, and in the summer the couple married in Lugdunum (modern-day Lyon , France), of which Severus was the governor. The marriage proved happy, and Severus cherished Julia and her political opinions. Julia built "the most splendid reputation" by applying herself to letters and philosophy. They had two sons, Lucius Septimius Bassianus (later nicknamed Caracalla, born 4 April 188 in Lugdunum) and Publius Septimius Geta (born 7 March 189 in Rome). In 191, on
17100-417: The granting of tribunicia potestas in 23 BC, these were only ratifications of the powers he already possessed. Most modern historians use 27 BC as the start date of the Roman Empire. This is mostly a symbolic date, as the Republic had essentially disappeared many years earlier. Ancient writers often ignore the legal implications of Augustus' reforms and simply write that he "ruled" Rome following
17271-419: The help of the military, and he returned the sentiment. Severus ordered the execution of a large number of Senators on charges of corruption or conspiracy against him and replaced them with his favourites. Although his actions turned Rome more into a military dictatorship, he was popular with the citizens of Rome, having stamped out the rampant corruption of Commodus' reign. When he returned from his victory over
17442-414: The highest imperial title, it was generally not used to indicate the office of Emperor itself, as ordinary people and writers had become accustomed to Imperator . In the East the title was initially translated as Sebastos , but the form Augoustos eventually became more common. Emperors after Heraclius styled themselves as Basileus , but Augoustos still remained in use in a lesser form up until
17613-445: The highest importance in the Republic, making the power attached to those offices permanent, and preventing anyone with similar aspirations from accumulating or maintaining power for themselves. Julius Caesar had been pontifex maximus since 64 BC; held the offices of consul and dictator five times since 59 BC, and was appointed dictator in perpetuity in 44 BC, shortly before his assassination . He had also become
17784-567: The horoscopes of prospective brides. The Historia Augusta relates that he heard of a woman in Syria of whom it had been foretold that she would marry a king, and so Severus sought her as his wife. This woman was an Emesene Syrian named Julia Domna . Her father, Julius Bassianus , descended from the Arab Emesene dynasty and served as a high priest to the local cult of the sun god Elagabal . Domna's older sister, Julia Maesa , would become
17955-494: The introduction of the three new legions: I, II and III Parthica . He garrisoned Legio II Parthica at Albanum , only 20 kilometres (12 mi) from Rome. He gave his soldiers a donative of a thousand sesterces (250 denarii ) each, and raised the annual wage for a soldier in the legions from 300 to 400 denarii . Severus was the first Roman emperor to station some of the imperial army in Italy. He realized that Rome needed
18126-488: The local Punic language fluently, but he was also educated in Latin and Greek, which he spoke with a slight accent. Little else is known of the young Severus' education but, according to Cassius Dio , the boy had been eager for more education than he actually received. Presumably, Severus received lessons in oratory : at the age of 17, he gave his first public speech. Severus sought a public career in Rome in around 162. At
18297-492: The lowest rank as clarissimi . As a result, Italy began to decline in favour of the provinces, which resulted in the division of the Empire into two administrative units in 395: the Western Roman Empire , with its capital at Mediolanum (now Milan ), and the Eastern Roman Empire , with its capital at Constantinople (now Istanbul ). In 402, the Imperial residence was moved to Ravenna from Milan, confirming
18468-467: The loyalty of most of his allies, and – again through a formal process of senatorial consent – an increasing number of the titles and offices that had accrued to Caesar. In August 43 BC, following the death of both consuls of the year , Octavian marched to Rome and forced the Senate to elect him consul. He then formed the Second Triumvirate alongside Mark Antony and Lepidus , dividing
18639-421: The main title of the emperor. According to Suetonius , it was "not merely a new title but a more honorable one, inasmuch as sacred places too, and those in which anything is consecrated by augural rites are called "august" ( augusta ), from the increase ( auctus ) in dignity". It was also connected to the religious practice of augury , which was itself linked to Rome's founding by Romulus , and to auctoritas ,
18810-472: The marginalization of the former heartland of Italy to the empire had a profound cultural impact on the empire and its emperor, which adopted a more Hellenistic character. The Eastern emperors continued to be recognized in the Western kingdoms until the accession of Irene (r. 797–802), the first empress regnant . The Italian heartland was recovered during the reign of Justinian I (r. 527–565), but this
18981-499: The military structures. The new city, however, did not receive an urban prefect until 359 which raised it to the status of eastern capital. After the death of Theodosius in 395 and the subsequent division of the Empire, Italy was home base of the Western Roman Empire . As a result of Alaric's invasion in 402 the western seat was moved from Mediolanum to Ravenna . Alaric , king of Visigoths , sacked Rome itself in 410; something that had not happened for eight centuries. Northern Italy
19152-411: The most prominent of them: the consulship and censorship . This early period of the Empire is known as the " Principate ", derived from the title princeps used by the early emperors. The most important bases of the emperor's power were his supreme power of command ( imperium maius ) and tribunician power ( tribunicia potestas ) as personal qualities, separate from his public office. Originally,
19323-510: The murder of Caesar, or that he "ruled alone" after the death of Mark Antony. Most Romans thus simply saw the "emperor" as the individual that ruled the state, with no specific title or office attached to him. Augustus actively prepared his adopted son Tiberius to be his successor and pleaded his case to the Senate for inheritance on merit. After Augustus' death in AD ;14, the Senate confirmed Tiberius as princeps and proclaimed him as
19494-492: The need to promote religious harmony by promoting syncretism . He possibly issued an edict that punished conversion to Judaism and Christianity. A number of persecutions of Christians occurred in the Roman Empire during his reign and were traditionally attributed to Severus by the early Christian community. A decree by Severus against the Christians is mentioned in the Historia Augusta , an unreliable mix of fact and fiction. Early church historian Eusebius described Severus as
19665-447: The new augustus . Tiberius had already received imperium maius and tribunicia potestas in AD 4, becoming legally equal to Augustus but still subordinate to him in practice. The "imperial office" was thus not truly defined until the accession of Caligula , when all of Tiberius' powers were automatically transferred to him as a single, abstract position that was symbolized by his sacred title of augustus . The legal authority of
19836-667: The nights in summer and winter, respectively. Having thus been conveyed through practically the whole of the hostile country (for he actually was conveyed in a covered litter most of the way, on account of his infirmity), he returned to the friendly portion, after he had forced the Britons to come to terms, on the condition that they should abandon a large part of their territory. By 210 Severus' campaigning had made significant gains, despite Caledonian guerrilla tactics and purportedly heavy Roman casualties. The Caledonians sued for peace, which Severus granted on condition they relinquish control of
20007-538: The number of Roman citizens throughout the empire. The surviving totals were 4,063,000 in 28 BC, 4,233,000 in 8 BC, and 4,937,000 in AD 14, but it is still debated whether these counted all citizens, all adult male citizens, or citizens sui iuris . Estimates for the population of mainland Italy, including Cisalpine Gaul, at the beginning of the 1st century range from 6,000,000 according to Karl Julius Beloch in 1886, to 14,000,000 according to Elio Lo Cascio in 2009. During
20178-410: The powers of command where divided in consular imperium for Rome and proconsular imperium for the provinces . This division became obsolete in 19 BC, when Augustus was given consular imperium – despite leaving the consulship in 23 BC – and thus control over all troops. This overwhelming power was referred to as imperium maius to indicate its superiority to other holders of imperium , such as
20349-469: The principal author of the decline of the Roman empire." According to Gibbon, "his daring ambition [...] was never diverted from its steady course by the allurements of pleasure, the apprehension of danger, or the feelings of humanity." His enlargement of the Limes Tripolitanus secured Africa , the agricultural base of the empire where he was born. His victory over the Parthian Empire was for
20520-448: The protectors of the Church. The territorial divisions of the Tetrarchy were maintained, and for most of the following century the Empire was ruled by two senior emperors, one in the West (with Milan and later Ravenna as capital) and another in the East (with Constantinople as capital). This division became permanent on the death of Theodosius I in 395, when he was succeeded by his sons Honorius and Arcadius . The two halves of
20691-577: The purity and silver weight of the denarius again, to 54% and 1.82 grams, respectively. Severus' currency debasement was the largest since the reign of Nero , compromising the long-term strength of the economy. Severus was also distinguished for his buildings. Apart from the triumphal arch in the Roman Forum carrying his full name, he also built the Septizodium in Rome. He enriched his native city of Leptis Magna , including commissioning
20862-559: The rank of Caesar , which implied some claim to the succession. With his rear safe, he moved to the East and crushed Niger's forces at the Battle of Issus (194). While campaigning against Byzantium , he ordered that the tomb of his fellow-Carthaginian Hannibal be covered with fine marble. He devoted the following year to suppressing Mesopotamia and other Parthian vassals who had backed Niger. Afterwards, Severus declared his son Caracalla as his successor, which caused Albinus to be hailed emperor by his troops and to invade Gaul. After
21033-440: The recognition of the Senate. Other "usurpers" controlled, if briefly, the city of Rome, such as Nepotianus and Priscus Attalus . In the East, the possession of Constantinople was the essential element of legitimacy, yet some figures such as Procopius are treated as usurpers. Rival emperors who later gained recognition are not always considered legitimate either; Vetranio had the formal recognition by Constantius II yet he
21204-487: The recommendation of his relative Gaius Septimius Severus, the emperor Marcus Aurelius ( r. 161–180 ) granted him entry into the senatorial ranks. Membership in the senatorial order was a prerequisite to attain positions within the cursus honorum and to gain entry into the Roman Senate. Nevertheless, it appears that Severus' career during the 160s met with some difficulties. It is likely that he served as
21375-545: The region's interior and escape back into the Sahara . In 208 Severus travelled to Britain with the intention of conquering Caledonia . Modern archaeological discoveries illuminate the scope and direction of his northern campaign. Severus probably arrived in Britain with an army of over 40,000, considering some of the camps constructed during his campaign could house this number. He strengthened Hadrian's Wall and reconquered
21546-406: The reverence of the emperor, making anything related to him sacer (sacred). He declared himself Jovius , the son of Jupiter , and his partner Maximian was declared Herculius , son of Hercules . This divine claim was maintained after the rise of Christianity, as emperors regarded themselves as the chosen rulers of God. The emperor no longer needed the Senate to ratify his powers, so he became
21717-545: The size of the Roman provinces by doubling their number to reduce the power of the provincial governors. He grouped the provinces into several dioceses (Latin: diocesis) and put them under the supervision of the Imperial vicarius (vice, deputy), who was the head of the diocese. During the Crisis of the Third Century the importance of Rome declined because the city was far from the troubled frontiers. Diocletian and his colleagues usually resided in four Imperial seats. The Augusti, Diocletian and Maximian , who were responsible for
21888-436: The sole source of law. These new laws were no longer shared publicly and were often given directly to the praetorian prefects – originally the emperor's bodyguard, but now the head of the new praetorian prefectures – or with private officials. The emperor's personal court and administration traveled alongside him, which further made the Senate's role redundant. Consuls continued to be appointed each year, but by this point, it
22059-460: The son of Publius Septimius Geta and Fulvia Pia , Septimius Severus came from a wealthy and distinguished family of equestrian rank. On his mother's side, he descended from Roman immigrants (the Fulvii) who had intermarried with locals of Libyan origin. His father, Publius Septimius Geta, hailed from a family of Libyan-Punic origin. Severus had thus Italic and North African ( Punic ) ancestry. He
22230-643: The southern foot of the Alps . Under Augustus, the peoples of today's Aosta Valley and of the western and northern Alps were subjugated (so the western border of Roman Italy was moved to the Varus river ), and the Italian eastern border was brought to the Arsia in Istria . Lastly, in the late 3rd century, Italy came to also include the islands of Sicily , Corsica and Sardinia , as well as Raetia and part of Pannonia . The city of Emona (modern Ljubljana , Slovenia)
22401-496: The specifically Christian idea that the emperor was God's chosen ruler on earth, a special protector and leader of the Christian Church, a position later termed Caesaropapism . In practice, an emperor's authority on Church matters was frequently subject to challenge. The Western Roman Empire collapsed in the late 5th century after multiple invasions by Germanic barbarian tribes, with no recognised claimant to Emperor of
22572-420: The succession or to divide the administration of the empire between them. The office of emperor was thought to be distinct from that of a rex ('king'). Augustus, the first emperor, resolutely refused recognition as a monarch. For the first three hundred years of Roman emperors, efforts were made to portray the emperors as leaders of the Republic, fearing any association with the kings who ruled Rome prior to
22743-470: The throne . Despite this, elements of the republican institutional framework (Senate, consuls, and magistrates) were preserved even after the end of the Western Empire. Constantine the Great , the first Christian emperor, moved the capital from Rome to Constantinople , formerly known as Byzantium , in 330 AD. Roman emperors had always held high religious offices; under Constantine there arose
22914-418: The title continued to be used for a time, with emperors registering the number of times they were hailed imperator . The title became the main appellation of the ruler by the time of Vespasian . After the Tetrarchy , emperors began to be addressed as dominus noster ("our Lord"), although imperator continued to be used. The appellation of dominus was known and rejected by Augustus, but ordinary men of
23085-485: The title of caesar . The Senate still exercised some power during this period, as evidenced by his decision to declare Nero a "public enemy", and did influence in the succession of emperors. Following the murder of Domitian in AD 96, the Senate declared Nerva , one of their own, as the new emperor. His "dynasty", the Antonine , continued the adoptive system until the reign of Marcus Aurelius (r. 161–180). Marcus
23256-473: The title of consul was Constans II , who was also the last Eastern emperor to visit Rome. It's possible that later emperors also used it as an honorary title, as the office of consul was not abolished until 892, during the reign of Leo VI . During the Dominate it became increasingly common for emperors to raise their children directly to augustus (emperor) instead of caesar (heir), probably because of
23427-418: The title was Junius Blaesus in AD 22, after which it became a title reserved solely for the sovereign. Augustus used Imperator instead of his first name ( praenomen ), becoming Imperator Caesar instead of Caesar Imperator . From this the title slowly became a synonym of the office, hence the word "emperor". Tiberius , Caligula and Claudius avoided using the title, but it is recorded that Caligula
23598-545: The title were Valentinian III and Marcian , in the 5th century. The only surviving document to directly refer to the emperor's power is the Lex de imperio Vespasiani , written shortly after Vespasian 's formal accession in December 69. The text, of which only the second part survives, states that Vespasian is allowed to: make treaties; hold sessions and propose motions to the Senate; hold extraordinary sessions with legislative power; endorse candidates in elections; expand
23769-409: The tribunes, such as sacrosanctity , since 36 BC. With this powers, he could veto any act or proposal of any magistrate, propose laws and convoke the Senate. His sacrosanctity also made him untouchable, and any offence against him could be treated as a crime of treason. The tribunician power was arguably the most stable and important of the emperor's powers. Despite being a perpetual title, it
23940-514: The triumph of Aemilius Paulus . It was a title held with great pride: Pompey was hailed imperator more than once, as was Sulla and Julius Caesar . However, as noted by Cassius Dio , the meaning of the title changed under the new monarchy, and came to denote "the possession of the supreme power". Both Dio and Suetonius refer to Caesar as the first one to assume imperator as a proper name (a praenomen imperatoris ), but this seems to be an anachronism . The last ordinary general to be awarded
24111-461: The two emperors. One of the two following praefecti was the famous jurist Papinian . Executions of senators did not stop: Cassius Dio records that many of them were put to death, some after being formally tried. After the assassination of Gaius Fulvius Plautianus in the rest of his reign, he relied more on the advice of his clever and educated wife, Julia Domna , in the administration of the empire. Upon his arrival at Rome in 193, Severus discharged
24282-507: The vague terms of "second" or "little emperor". Despite having a successful reign himself, Diocletian's tetrarchic system collapsed as soon as he retired in 305. Constantine I , the son of tetrarch Constantius I , reunited the empire in 324 and imposed the principle of hereditary succession which Diocletian intended to avoid. Constantine was also the first emperor to convert to Christianity , and emperors after him, especially after its officialization under Theodosius I , saw themselves as
24453-400: The water caused great suffering to the Romans, and when they became scattered, they would be attacked. Then, unable to walk, they would be slain by their own men, in order to avoid capture, so that a full fifty thousand died. But Severus did not desist until he approached the extremity of the island. Here he observed most accurately the variation of the sun's motion and the length of the days and
24624-445: The whole of it, invaded Caledonia. But as he advanced through the country he experienced countless hardships in cutting down the forests, levelling the heights, filling up the swamps, and bridging the rivers; but he fought no battle and beheld no enemy in battle array. The enemy purposely put sheep and cattle in front of the soldiers for them to seize, in order that they might be lured on still further until they were worn out; for in fact,
24795-674: Was Constantine XI Palaiologos , who died during the Fall of Constantinople to the Ottoman Empire in 1453. After conquering the city, Ottoman sultans adopted the title " Caesar of the Romans" ( kayser-i Rûm ). A Byzantine group of claimant emperors existed in the Empire of Trebizond until its conquest by the Ottomans in 1461, although they had used a modified title since 1282. Modern historians conventionally regard Augustus as
24966-415: Was Vitellius , who adopted the name Germanicus instead. Most emperors used it as their nomen – with Imperator as their praenomen – until the reign of Antoninus Pius , when it permanently became part of the formula Imperator Caesar [full name] Augustus . In the 3rd century, caesars also received the honorific of nobilissimus ("most noble"), which later evolved into a separate title. During
25137-555: Was able to leave Africa, Mauri tribesmen invaded southern Spain. Control of the province was handed over to the emperor, while the Senate gained temporary control of Sardinia as compensation . Thus, Septimius Severus spent the remainder of his second term as quaestor on the island of Sardinia. In 173, Severus' cousin Gaius Septimius Severus was appointed proconsul of the province of Africa Proconsularis and chose Severus as one of his two legati pro praetore ,
25308-481: Was also sub-divided into provinces, it remained the centre of the Western Roman Empire and had a status that gave her the name of domina provinciarum ("ruler of the provinces") by glossators of the Corpus Iuris Civilis . The Bishop of Rome had gained importance gradually from the reign of Constantine , and was given religious primacy with the Edict of Thessalonica under Theodosius I . Italy
25479-508: Was also used to distinguish a junior co-emperor ( basileus ) from his senior colleague ( basileus autokrator ). By the times of the Palaiologos , there were two distinct ceremonies for the accession of an emperor: first an acclamation as basileus , and later a coronation as autokrator (which also included being raised on a shield). These rites could happen years apart. The Eastern Empire became not only an absolute monarchy but also
25650-512: Was always renewed each year, which often coincided with the beginning of a new regnal year (although " regnal years " were not officially adopted until Justinian I ). The office of censor was not fully absorbed into the imperial office until the reign of Domitian , who declared himself "perpetual censor" ( censor perpetuus ) in AD 85. Before this, the title had been only used by Claudius (47), Vespasian and Titus (both in 73). The emperor also had power over religious affairs, which led to
25821-446: Was an office often occupied by the emperor himself, who now had complete control over the bureaucratic apparatus. Diocletian did preserve some Republican traditions, such as the tribunicia potestas . The last known emperor to have used it was Anastasius I , at the start of the 6th century. Anastasius was also the last attested emperor to use the traditional titles of proconsul and pater patriae . The last attested emperor to use
25992-622: Was assassinated in 480 and may have been recognized by Odoacer. Italy remained under Odoacer and his Kingdom of Italy , and then under the Ostrogothic Kingdom . The Germanic successor states under Odoacer and Theodoric the Great continued to use the Roman administrative apparatus, as well as being nominal subjects of the Eastern emperor at Constantinople . In 535 Roman Emperor Justinian invaded Italy which suffered twenty years of disastrous war. In August 554, Justinian issued
26163-599: Was attacked by Attila 's Huns in 452. Rome was sacked in 455 again by the Vandals under the command of Genseric . According to Notitia Dignitatum , one of the very few surviving documents of Roman government updated to the 420s, Roman Italy was governed by a praetorian prefect , Prefectus praetorio Italiae (who also governed the Diocese of Africa and the Diocese of Pannonia ), one vicarius , and one comes rei militaris . The regions of Italy were governed at
26334-401: Was by definition a plebeian , whereas Augustus, although born into a plebeian family, had become a patrician when he was adopted into the gens Julia . By adopting the role of a tribune, Augustus was presenting himself as the representative of the common man and the protector of democracy. As always, this was not a sudden grant of power; Augustus had been receiving several powers related to
26505-452: Was described as "Libyan by race", by the Roman historian and senator Cassius Dio . Due to his family background he is considered the first provincial emperor, as he was the first emperor not only born in the provinces but also into a provincial family of non-Italian origin. Severus' father, an obscure provincial, held no major political status, but he had two cousins, Publius Septimius Aper and Gaius Septimius Severus, who served as consuls under
26676-419: Was hailed imperator by the Senate on his accession, indicating that it was already considered an integral part of the dignity. It was not until the late reign of Nero , in AD 66, that imperator became once more part of the emperor's nomenclature. Virtually all emperors after him used the praenomen imperatoris , with only a few variations under his successors Galba and Vitellius . The original meaning of
26847-419: Was invaded several times by the wandering Germanic peoples and fell under the control of Odoacer , when Romulus Augustus was deposed in 476 AD. Since then, no single authority was established in Italy as a whole except for a brief Period when the Byzantine Empire reconquered Italy. Even the modern Republic of Italy only consists of most of Italian region , excluding Corsica and some other areas. Following
27018-426: Was no distinction between emperors and usurpers, as many emperors started as rebels and were retroactively recognized as legitimate. The Lex de imperio Vespasiani explicitly states that all of Vespasian's actions are considered legal even if they happened before his recognition by the Senate. Ultimately, "legitimacy was a post factum phenomenon." Theodor Mommsen famously argued that "here has probably never been
27189-618: Was not relevant in the early Empire, although emperors still attempted to maintain a familiar connection between them; Tiberius , for example, married Julia the Elder , making him Augustus ' son-in-law. Vespasian , who took power after the collapse of the Julio-Claudian dynasty and the tumultuous Year of the Four Emperors , was the first emperor to openly declare his sons, Titus and Domitian , as his sole heirs, giving them
27360-473: Was officially enrolled in the Roman Senate . Between 170 and 180 his activities went largely unrecorded, in spite of the fact that he occupied an impressive number of posts in quick succession. The Antonine Plague had thinned the senatorial ranks and, with capable men now in short supply, Severus' career advanced more steadily than it otherwise might have. The sudden death of his father necessitated another return to Leptis Magna to settle family affairs. Before he
27531-407: Was overthrown and expelled to Dalmatia in favor of Romulus, continued to claim the title until his murder in 480. The Eastern court recognized this claim and Odoacer minted coins in his name, although he never managed to exercise real power. The death of Nepos left Zeno as the sole emperor of a (technically) reunited Roman Empire. The Roman Empire survived in the East for another 1000 years, but
27702-410: Was privileged by Augustus and his heirs, with the construction, among other public structures, of a dense network of Roman roads . The Italian economy flourished: agriculture, handicraft and industry had noticeable growth, allowing the export of goods to the provinces. The Italian population may have grown as well: three censuses were ordered by Augustus, in his role as Roman censor , in order to record
27873-412: Was proclaimed emperor at the age of 4. Many child emperors such as Philip II or Diadumenian never succeeded their fathers. These co-emperors all had the same honors as their senior counterpart, but they did not share the actual government, hence why junior co-emperors are usually not counted as real emperors by modern or ancient historians. There was no title to denote the "junior" emperor; writers used
28044-413: Was replaced with dominus ("lord"); the use of princeps and dominus broadly symbolizes the differences in the empire's government, giving rise to the era designations Principate and Dominate . The title is still found in some later sources, however. The poet Claudian , for example, describes Honorius as having been raised from " caesar " to " princeps " (instead of augustus ). The title survived
28215-617: Was reverted by the end of the century. Rome technically remained under imperial control , but was completely surrounded by the Lombards . Africa was lost to the Arabs in the early 7th century, and Rome eventually fell to the Lombards in 751, during the reign of Constantine V . The Frankish king Pepin the Short defeated them and received the favour of Pope Stephen II , who became the head of
28386-490: Was the easternmost town of Italy. At the beginning of the Roman Imperial era, Italy was a collection of territories with different political statuses. Some cities, called municipia , had some independence from Rome, while others, the coloniae , were founded by the Romans themselves. Around 7 BC, Augustus divided Italy into eleven regiones , as reported by Pliny the Elder in his Naturalis Historia : Italy
28557-486: Was the first emperor to actually use the title of "Roman emperor" (βασιλεύς Ῥωμαίων, Basileus Romaíon ). This was a response to the new line of emperors created by Charlemagne – although he was recognized as basileus of the Franks . By the 9th century the full imperial title became " basileus and autokrator of the Romans", usually translated as "Emperor and Autocrat of the Romans". The title autokrator
28728-409: Was the first emperor to rule alongside other emperors, first with his adoptive brother Lucius Verus , who succeeded jointly with him, and later with his son Commodus , who was proclaimed co- augustus in 177. Despite being the son of a previous emperor and having nominally shared government with him, Commodus' rule ended with his murder at the hands of his own soldiers. From his death in 192 until
28899-602: Was the real "usurper" (having been proclaimed by his troops). There were no true objective legal criteria for being acclaimed emperor beyond acceptance by the Roman army , which was really the true basis of imperial power. Common methods used by emperors to assert claims of legitimacy, such as support of the army, blood connections (sometimes fictitious) to past emperors, distributing one's own coins or statues, and claims to pre-eminent virtue through propaganda, were pursued just as well by many usurpers as they were by legitimate emperors. Septimius Severus notably declared himself as
29070-408: Was the title used by early writers before the term imperator became popular. In his Res Gestae , Augustus explicitly refers to himself as the princeps senatus . The title was also sometimes given to heirs, in the form of princeps iuventutis ("first of the youth"), a term that continued to be used during the Tetrarchy . In the era of Diocletian and beyond, princeps fell into disuse and
29241-483: Was unable to capture the fortress of Hatra , even after two lengthy sieges—just like Trajan, who had tried nearly a century before. During his time in the east, though, Severus also expanded the Limes Arabicus , building new fortifications in the Arabian Desert from Basie to Dumatha . Severus' relations with the Senate were never good. He was unpopular with them from the outset, having seized power with
