Septimius Severus (Latin: Lucius Septimius Severus Augustus;^[4] 11 April 145 – 4 February 211), also known as Severus, was Roman Emperor from 193 to 211. Severus was born in Leptis Magna in the province of Africa. As a young man he advanced through the customary succession of offices under the reigns of Marcus Aurelius and Commodus. Severus seized power after the death of 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 generals Pescennius Niger and Clodius Albinus. Niger was defeated in 194 at the Battle of Issus in Cilicia.^[5] Later that year Severus waged a short punitive campaign beyond the eastern frontier, annexing the Kingdom of Osroene as a new province.^[6] Severus defeated Albinus three years later at the Battle of Lugdunum in Gaul.^[7]

After solidifying his rule over the western provinces, Severus waged another brief, more successful war in the east against the Parthian Empire, sacking their capital Ctesiphon in 197 and expanding the eastern frontier to the Tigris.^[8] Furthermore, he enlarged and fortified the Limes Arabicus in Arabia Petraea.^[9] In 202, he campaigned in Africa and Mauretania against the Garamantes; capturing their capital Garama and expanding the Limes Tripolitanus along the southern frontier of the empire.^[10] Late in his reign he traveled to Britain, strengthening Hadrian's Wall and reoccupying the Antonine Wall. In 208 he invaded Caledonia modern Scotland, but his ambitions were cut short when he fell fatally ill in late 210.^[11] Severus died in early 211 at Eboracum,^[3] succeeded by his sons Caracalla and Geta. With the succession of his sons, Severus founded the Severan dynasty, the last dynasty of the empire before the Crisis of the Third Century.

Early life[link]

Family and education[link]

Septimius Severus was born on 11 April 145 at Leptis Magna (in modern Libya), son of Publius Septimius Geta and Fulvia Pia.^[2] Severus came from a wealthy, distinguished family of equestrian rank. He was of Italian Roman ancestry on his mother's side and of Punic or Libyan-Punic ancestry on his father's.^[12] Severus' father was an obscure provincial who held no major political status, but he had two cousins, Publius Septimius Aper and Gaius Septimius Severus, who served as consuls under emperor Antoninus Pius. 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.^[13] Severus' siblings were an older brother, Publius Septimius Geta, and a younger sister, Septimia Octavilla. Severus’s maternal cousin was Praetorian prefect and consul Gaius Fulvius Plautianus.^[14]

Septimius Severus was brought up at his home town of Leptis Magna. He spoke 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 had actually got. Presumably, Severus received lessons in oratory, and at age 17, he gave his first public speech.^[15]

Public service[link]

Sometime around 162, Septimius Severus set out for Rome seeking a public career. By recommendation of his "uncle", Gaius Septimius Severus, he was granted entry into the senatorial ranks by emperor Marcus Aurelius.^[16] Membership of the senatorial order was a prerequisite to attain the standard succession of offices known as the cursus honorum, and to gain entry into the Roman Senate. Nevertheless, it appears that Severus' career during the 160s was beset with some difficulties. It is likely that he served as a vigintivir in Rome, overseeing road maintenance in or near the city, and he may have appeared in court as an advocate.^[17] However, he omitted the military tribunate from the cursus honorum and was forced to delay his quaestorship until he had reached the required minimum age of 25.^[17] To make matters worse, the Antonine Plague swept through the capital in 166. With his career at a halt, Severus decided to temporarily return to Leptis, where the climate was healthier.^[18] 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 was officially enrolled in the Roman Senate.^[19]

Between 170 and 180 the activities of Septimius Severus went largely unrecorded, in spite of the fact that he occupied an impressive number of posts in quick succession. The Antonine Plague had severely thinned the senatorial ranks and with capable men now in short supply, Severus' career advanced more steadily than it otherwise might have. After his first term as quaestor, he was ordered to serve a second term at Baetica (southern Spain),^[20] but circumstances prevented Severus from taking up the appointment. The sudden death of his father necessitated a return to Leptis Magna to settle family affairs. Before he was able to leave Africa, Moorish 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.^[21] In 173, Severus' kinsman Gaius Septimius Severus was appointed proconsul of the Africa Province. The elder Severus chose his cousin as one of his two legati pro praetore.^[22] Following the end of this term, Septimius Severus travelled back to Rome, taking up office as tribune of the plebs, with the distinction of being candidatus of the emperor.^[23]

Marriages[link]

Septimius Severus was already in his early thirties at the time of his first marriage. In about 175, he married a woman from Leptis Magna named Paccia Marciana.^[23] It is likely that he met her during his tenure as legate under his uncle. Marciana's name reveals that she was of Punic or Libyan origin but virtually nothing else is known of her. Septimius Severus does not mention her in his autobiography, though he later commemorated her with statues when he became Emperor. The Historia Augusta claims that Marciana and Severus had two daughters but their existence is nowhere else attested. It appears that the marriage produced no children, despite lasting for more than ten years.^[23]

Marciana died of natural causes around 186.^[24] Septimius Severus was now in his forties and still childless. Eager to remarry, he began enquiring into the horoscopes of prospective brides. The Historia Augusta relates that he heard of a woman in Syria who had been foretold that she would marry a king, and therefore Severus sought her as his wife.^[25] This woman was an Emesan noble Arab woman named Julia Domna. Her father, Julius Bassianus, descended from the royal house of Samsigeramus and Sohaemus, and served as a high priest to the local cult of the sun god Elagabal.^[26] Domna's older sister was Julia Maesa, later grandmother to the future emperors Elagabalus and Alexander Severus.

Bassianus accepted Severus' marriage proposal in early 187, and the following summer he and Julia were married.^[27] The marriage proved to be a happy one and Severus cherished his wife and her political opinions, since she was very well-read and keen on philosophy. Together, they had two sons, Lucius Septimius Bassianus (later nicknamed Caracalla, b. 4 April 188) and Publius Septimius Geta (b. 7 March 189).^[27]

Rise to power[link]

Tondo, probably from the year 199, Septimius Severus with Julia Domna, Caracalla and Geta, whose face is smeared out.

In 191 Severus received from the Emperor Commodus the command of the legions in Pannonia. However, Commodus was assassinated the following year. Pertinax was acclaimed emperor but was killed by the Praetorian Guard in early 193. In response to the murder of Pertinax, Severus' soldiers proclaimed him Emperor at Carnuntum, whereupon he hurried to Italy. Pertinax's successor in Rome was Didius Julianus, who had bought the emperorship in an auction. Julianus was condemned to death by the Senate and killed, and Severus took possession of Rome without opposition. He executed Pertinax's murderers and dismissed the rest of the Praetorian Guard, populating its ranks with loyal troops from his own legions.

The legions of Syria, however, had proclaimed Pescennius Niger emperor. At the same time, Severus felt it was reasonable to offer Clodius Albinus, the powerful governor of Britannia who had probably supported Didius against him, the rank of Caesar, which implied some claim to succession. With his rearguard safe, he moved to the East and crushed Niger's forces at the Battle of Issus. The following year was devoted to suppressing Mesopotamia and other Parthian vassals who had backed Niger. When afterwards Severus declared openly his son Caracalla as successor, Albinus was hailed emperor by his troops and moved to Gallia. Severus, after a short stay in Rome, moved northwards to meet him. On 19 February 197, in the Battle of Lugdunum, with an army of about 75,000 men, mostly composed of Illyrian, Moesian and Dacian legions, Severus defeated and killed Clodius Albinus, securing his full control over the Empire.

In early 197 he departed Rome and travelled to the east by sea. He embarked at Brundisium and probably landed at the port of Aegeae in Cilicia,^[28] traveling to Syria by land. He immediately gathered his army and crossed the Euphrates.^[29] Abgar IX, 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.^[30] At this time King Khosrov I of Armenia, also sent hostages, money and gifts.^[31] Severus traveled onwards to Nisibis, which his general Julius Laetus had prevented from falling into enemy hands.^[32] Afterwards, Severus returned to Syria for a time to plan a much more ambitious campaign.

The following year he led another, more successful campaign against the Parthian Empire, reportedly in retaliation for the support given to Pescennius Niger. The Parthian capital Ctesiphon was sacked by the legions and the northern half of Mesopotamia was annexed to the Empire. However, like Trajan over a century before, he was unable to capture the fortress of Hatra even after two lengthy sieges. During his time in the east he also expanded the Limes Arabicus, building new fortifications in the Arabian Desert from Basie to Dumata.^[9]

His relations with the Roman Senate were never good. He was unpopular with them from the outset, having seized power with the help of the military, and he returned the sentiment. Severus ordered the execution of dozens of Senators on charges of corruption and conspiracy against him, replacing them with his own favorites.

Upon his arrival at Rome in 193, he discharged the Praetorian Guard which had murdered Pertinax and auctioned the Roman Empire to Didius Julianus. Its members were stripped of their ceremonial armour and ordered to remove themselves within 100 miles of the city on pain of death.^[33] Severus then raised a new Guard composed of 50,000 loyal soldiers mainly camped at Albanum, near Rome (also probably to grant the emperor a kind of centralized reserve). During his reign the number of legions was also increased from 25/30 to 33. He also increased the number of auxiliary corps (numerii), many of these troops coming from the Eastern borders. Additionally the annual wage for a soldier was raised from 300 to 500 denarii.

Although his actions turned Rome into a military dictatorship, he was popular with the citizens of Rome, having stamped out the rampant corruption of Commodus's reign. When he returned from his victory over the Parthians, he erected the Arch of Septimius Severus in Rome. According to Cassius Dio,^[34] however, after 197 Severus fell heavily under the influence of his Praetorian Prefect, Gaius Fulvius Plautianus, who came to have almost total control of most branches of the imperial administration. Plautianus's daughter, Fulvia Plautilla, was married to Severus's son, Caracalla. Plautianus’s excessive power came to an end in 205, when he was denounced by the Emperor's dying brother and killed.^[35] However, the two following praefecti, including the jurist Aemilius Papinianus, received even larger powers.

Religious matters[link]

Christians were persecuted during the reign of Septimius Severus. Severus allowed the enforcement of policies already long-established, which meant that Roman authorities did not intentionally seek out Christians, but when people were accused of being Christians they would be forced to either curse Jesus and make an offering to Roman gods, or be executed. Furthermore, wishing to strengthen the peace by encouraging religious harmony through syncretism, Severus tried to limit the spread of the two groups who refused to yield to syncretism by outlawing conversions to Christianity or Judaism. Individual officials availed themselves of the laws to proceed with rigor against the Christians. Naturally the emperor, with his strict conception of law, did not hinder such partial persecution, which took place in Egypt and the Thebaid, as well as in Africa proconsularis and the East. Christian martyrs were numerous in Alexandria.^[36] No less severe were the persecutions in Africa, which seem to have begun in 197 or 198,^[37] and included the Christians known in the Roman martyrology as the martyrs of Madaura. Probably in 202 or 203 Felicitas and Perpetua suffered for their faith. Persecution again raged for a short time under the proconsul Scapula in 211, especially in Numidia and Mauritania. Later accounts also speak of a Gallic persecution, especially at Lyons, under Severus, but historians, based on archaeological and literary evidence, generally consider these events actually to have taken place under Emperor Marcus Aurelius.

Military activity[link]

The expansion of the African frontier during the reign of Severus (medium tan). Severus even briefly held a military presence in Garama in 203 (light tan).

In late 202 Severus launched a campaign in the province of Africa. The legate of Legio III Augusta Quintus Anicius Faustus had been fighting against the Garamantes along the Limes Tripolitanus for five years, capturing several settlements from the enemy such as Cydamus, Gholaia, Garbia, and their capital Garama – over 600 km south of Leptis Magna.^[38] During this time the province of Numidia was also enlarged: the empire annexed the settlements of Vescera, Castellum Dimmidi, Gemellae, Thabudeos, Thubunae, and Zabi.^[39] By 203 the entire southern frontier of Roman Africa had been dramatically expanded and re-fortified. Desert nomads could no longer safely raid the region's interior and escape back into the Sahara.

In 208 Severus traveled to Britain with the intention of conquering Caledonia. Modern archaeological discoveries have made the scope and direction of his northern campaign better understood.^[40] Severus likely arrived in Britain possessing an army over 40,000, considering some of the camps constructed during his campaign could house this number.^[41] He strengthened Hadrian's Wall and reconquered the Southern Uplands up to the Antonine Wall, which was also enhanced. Severus built a 165 acre camp south of the Antonine Wall at Trimontium, likely assembling his forces there. Severus then thrust north with his army across the wall into enemy territory. Retracing the steps of Agricola over a century previously, Severus rebuilt and garrisoned many abandoned Roman forts along the east coast, including Carpow which could house up to 40,000 soldiers.

An interesting story from around this time is when Severus' wife, Julia Domna, criticised the sexual morals of the Caledonian women, the wife of Caledonian chief Argentocoxos replied: "We fulfill the demands of nature in a much better way than do you Roman women; for we consort openly with the best men, whereas you let yourselves be debauched in secret by the vilest".^[42]

Cassius Dio's account of the invasion reads "Severus, accordingly, desiring to subjugate 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; 2 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 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. 3 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 the nights in summer and winter respectively. 4 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."^[43]

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 the Central Lowlands.^[44][45] This is evidenced by extensive Severan era fortifications in the Central Lowlands.^[46] The Caledonians, short on supplies and feeling their position becoming desperate, revolted later that year along with the Maeatae.^[47] Severus prepared for another protracted campaign within Caledonia. He was now intent on exterminating the Caledonians, telling his soldiers: “Let no one escape sheer destruction, No one our hands, not even the babe in the womb of the mother, If it be male; let it nevertheless not escape sheer destruction.”^[48]

Severus' campaign was cut short when he fell fatally ill.^[49] He withdrew to Eboracum 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: they soon withdrew south permanently to Hadrian's Wall.^[50]

He is famously said to have given the advice to his sons: "Be harmonious, enrich the soldiers, and scorn all other men" before he died at Eboracum (York) on 4 February 211.^[51]

Upon his death in 211, Severus was deified by the Senate and succeeded by his sons, Caracalla and Geta, who were advised by his wife Julia Domna.^[52] The cameo glass Portland Vase is said to have been excavated in the 16th century from his tomb.

Assessment and legacy[link]

Part of the Imperial Palace complex on the Palatine Hill overlooking the Circus Maximus

Though his military expenditure was costly to the empire, Severus was the strong, able ruler that Rome needed at the time. His enlargement of the Limes Tripolitanus secured Africa, the agricultural base of the empire. His victory over Parthia was total, establishing a new status quo in the east which secured Nisibis and Singara for the Empire. His policy of an expanded and better-rewarded army was criticized by his contemporary Dio Cassius 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 army.

In order to maintain his enlarged military he debased the Roman currency drastically. Upon his accession he decreased the silver purity of the denarius from 81.5% to 78.5%. However, the silver weight actually increased, rising from 2.40 grams to 2.46 grams. Nevertheless the following year he debased the denarius substantially because of rising military expenditures. The silver purity decreased from 78.5% to 64.5% — the silver weight dropping from 2.46 grams to 1.98 grams. In 196 he reduced the purity and silver weight of the denarius again, to 54% and 1.82 grams respectively.^[53] Severus' currency debasement was the largest since the reign of Nero, compromising the long-term strength of the economy. However, Severus minted a much higher volume of denarii than his predecessors, alleviating some of the negative effects of debasement.

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 and enriched greatly his native city of Leptis Magna (including another triumphal arch on the occasion of his visit of 203). The greater part of the Flavian Palace overlooking the Circus Maximus was undertaken in his reign.

The Roman emperor was the ruler of the Roman State during the imperial period (starting at about 27 BC). The Romans had no single term for the office although at any given time, a given title was associated with the emperor. If a man was "proclaimed emperor" this normally meant he was proclaimed augustus, or (for generals) imperator (from which English emperor ultimately derives). Several other titles and offices were regularly accumulated by emperors, such as caesar, princeps senatus, consul and Pontifex Maximus. The power of emperors was generally based on the accumulation of powers from republican offices and the support of the army.

Roman emperors refused to be considered "kings", instead claiming to be leaders of a republic, however nominal. The first emperor, Augustus, resolutely refused recognition as a monarch.^[1] Although Augustus could claim that his power was authentically Republican, his successor, Tiberius, could not convincingly make the same claim.^[2] Nonetheless, the Republican institutional framework (senate, consuls, magistracies etc.) was preserved until the very end of the Western Empire.

By the time of Diocletian, emperors were openly "monarchs",^[3] but the contrast with "kings" was maintained: Although the imperial succession was, de facto, generally hereditary, it was only hereditary if there was a suitable candidate acceptable to the army and the bureaucracy^[4] so the principle of automatic inheritance was not adopted. The Eastern (Byzantine) emperors ultimately adopted the formal title of Basileus, which had meant king in Greek, but became a title reserved solely for the "Roman" emperor (and the ruler of the Sassanid Empire). Other kings were referred to as regas.

In addition to their pontifical office, emperors were given divine status: initially after their death, but later from their accession. As Christianity prevailed over paganism, the emperor's religious status changed to that of Christ's regent on earth, and the Empire's status was seen as part of God's plan to Christianize the world.

The Western Roman Empire was dealt fatal blows by a set of military coups d'état in the Italian Peninsula in 475 and 476. The division of the empire into Western and Eastern was formally abolished as a separate entity by Emperor Zeno after the death of the last Western Emperor Julius Nepos in 480. Zeno's successors ruled from Constantinople (modern Istanbul) through the conquest of that city by the Ottoman Turks in 1453. The last Roman Emperor, Constantine XI died in hand to hand combat defending the capital. A dynasty of claimants maintained the Imperial tradition in the province of Chaldia through its conquest by the Ottomans in 1461.

Rome used no single constitutional office, title or rank exactly equivalent to the English title "Roman emperor". Romans of the Imperial era used several titles to denote their emperors, and all were associated with the pre-Imperial, Republican era. "Roman emperor" is a convenient shorthand used by historians to express the complex nature of the person otherwise known as princeps - itself a republican honorific.

The emperor's legal authority derived from an extraordinary concentration of individual powers and offices extant in the Republic rather than from a new political office; emperors were regularly elected to the offices of consul and censor. Among their permanent privileges were the traditional Republican title of princeps senatus (leader of the Senate) and the religious office of pontifex maximus (chief priest of Roman state). Every emperor held the latter office and title until Gratian surrendered it in 382 AD to St. Siricius; it eventually became an auxiliary honor of the Bishop of Rome.

These titles and offices conferred great personal prestige (dignitas) but the basis of an emperor's powers derived from his auctoritas: this assumed his greater powers of command (imperium maius) and tribunician power (tribunicia potestas) as personal qualities, independent of his public office. As a result, he formally outranked provincial governors and ordinary magistrates. He had the right to enact or revoke sentences of capital punishment, was owed the obedience of private citizens (privati) and by the terms of the ius auxiliandi could save any plebeian from any patrician magistrate's decision. He could veto any act or proposal of any magistrate, including the tribunes of the people (ius intercedendi or ius intercessionis). His person was held to be sacrosanct.

Roman magistrates on official business were expected to wear the form of toga associated with their office; different togas were worn by different ranks; senior magistrates had the right to togas bordered with purple. A triumphal imperator of the Republic had the right to wear the toga picta (of solid purple, richly embroidered) for the duration of the triumphal rite. During the Late Republic, the most powerful had this right extended. Pompey and Caesar are both thought to have worn the triumphal toga and other triumphal dress at public functions. Later emperors were distinguished by wearing togae purpurae, purple togas; hence the phrase "to don the purple" for the assumption of imperial dignity.

The titles customarily associated with the imperial dignity are imperator ("commander", lit. "one who prepares against"), which emphasizes the emperor's military supremacy and is the source of the English word emperor; caesar, which was originally a name but it came to be used for the designated heir (as Nobilissimus Caesar, "Most Noble Caesar") and was retained upon accession. The ruling emperor's title was the descriptive augustus ("majestic" or "venerable", which had tinges of the divine), which was adopted upon accession. In Greek, these three titles were rendered as autokratōr ("Αὐτοκράτωρ"), kaisar ("Καίσαρ"), and augoustos ("Αὔγουστος") or sebastos ("Σεβαστός") respectively. In Diocletian's Tetrarchy, the traditional seniorities were maintained: Augustus was reserved for the two senior emperors and Caesar for the two junior emperors - each delegated a share of power and responsibility but each an emperor-in-waiting, should anything befall his senior.

As princeps senatus (lit., "first man of the senate"), the emperor could receive foreign embassies to Rome; some emperors (such as Tiberius) are known to have delegated this task to the Senate. In modern terms these early emperors would tend to be identified as chiefs of state. The office of princeps senatus, however, was not a magistracy and did not own imperium. At some points in the Empire's history, the emperor's power was nominal; powerful praetorian prefects, masters of the soldiers and on a few occasions, other members of the Imperial family including Imperial mothers and grandmothers acted as the true source of power.

[edit] Imperator

The title imperator dates back to the Roman Republic, when a victorious commander could be hailed as imperator in the field by his troops. The Senate could then award (or withhold) the extraordinary honour of a triumph; the triumphal commander retained the title until the end of his magistry.^[5] Roman tradition held the first triumph as that of Romulus but the first attested recipient of the title imperator in a triumphal context is Aemilius Paulus in 189 BC.^[5] It was a title held with great pride: Pompey was hailed imperator more than once, as was Sulla, but it was Julius Caesar who first used it permanently - according to Dio, this was a singular and excessive form of flattery granted by the Senate, passed to Caesar's adopted heir along with his name and virtually synonymous with it.^[6]

In 38 BC Agrippa refused a triumph for his victories under Octavian's command and this precedent established the rule that the princeps should assume both the salutation and title of imperator. It seems that from then on Octavian (later first emperor Augustus) used imperator as a praenomen (Imperator Caesar not Caesar imperator). From this the title came to denote the supreme power and was commonly used in that sense. Otho was the first to imitate Augustus but only with Vespasian did imperator (emperor) become the official title by which the ruler of the Roman Empire was known.

[edit] Princeps

The word princeps (plural principes), meaning "first", was a republican term used to denote the leading citizen(s) of the state. It was a purely honorific title with no attached duties or powers. It was the title most preferred by Caesar Augustus as its use implies only primacy, as opposed to another of his titles, imperator, which implies dominance. Princeps, because of its republican connotation, was most commonly used to refer to the emperor in Latin (although the emperor's actual constitutional position was essentially "pontifex maximus with tribunician power and imperium superseding all others") as it was in keeping with the façade of the restored Republic; the Greek word basileus ("king") was modified to be synonymous with emperor (and primarily came into favour after the reign of Heraclius) as the Greeks had no republican sensibility and openly viewed the emperor as a monarch.

In the era of Diocletian and beyond, princeps fell into disuse and was replaced with dominus ("lord");^{[citation needed]} later emperors used the formula Imperator Caesar NN. Pius Felix (Invictus) Augustus. NN representing the individual's personal name, Pius Felix, meaning "Pious and Blest", and Invictus meaning "undefeated". The use of princeps and dominus broadly symbolise the differences in the empire's government, giving rise to the era designations "Principate" and "Dominate".

First Roman emperor[link]

At the end of the Roman Republic no new, and certainly no single title indicated the individual who held supreme power. Insofar as emperor could be seen as the English translation of imperator, then Julius Caesar had been an emperor, like several Roman generals before him. Instead, by the end of the civil wars in which Julius Caesar had led his armies, it became clear on the one hand that there was certainly no consensus to return to the old-style monarchy, and that on the other hand the situation where several officials, bestowed with equal power by the senate, fought one another had to come to an end.

Julius Caesar, then Octavian after him, accumulated offices and titles of the highest importance in the Republic, making the power attached to these offices permanent, and preventing anyone with similar aspirations from accumulating or maintaining power for themselves. However, Julius Caesar, unlike those after him, did so without the Senate's vote and approval^{[citation needed]}.

Julius Caesar held the Republican offices of consul four times and dictator five times, was appointed dictator in perpetuity (dictator perpetuo) in 45 BC and had been "pontifex maximus" for several decades. He gained these positions by senatorial consent. By the time of his assassination in 44 BC he was the most powerful man in Rome.

In his will, Caesar appointed his adopted son Octavian as his heir. On Caesar's death, Octavian inherited his adoptive father's property and lineage, 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. A decade after Caesar's death, Octavian's victory over his erstwhile ally Mark Antony at Actium put an end to any effective opposition and confirmed Octavian's supremacy.

In 27 BC, Octavian appeared before the Senate and offered to retire from active politics and government; the Senate not only requested he remain, but increased his powers and made them lifelong, awarding him the title of Augustus (the elevated or divine one, somewhat less than a god but approaching divinity). Octavian stayed in office till his death; the sheer breadth of his superior powers as princeps and permanent imperator of Rome's armies guaranteed the peaceful continuation of what nominally remained a republic. His "restoration" of powers to the Senate and the people of Rome was a demonstration of his auctoritas and pious respect for tradition.

Even at Augustus' death, some later historians such as Tacitus would say that the true restoration of the Republic might have been possible. Instead, Augustus actively prepared his adopted son Tiberius to be his replacement and pleaded his case to the Senate for inheritance through merit. The Senate disputed the issue but eventually confirmed Tiberius as princeps. Once in power, Tiberius took considerable pains to observe the forms and day-to-day substance of republican government.

The historians of the 1st centuries observed the dynastic continuity: if a hereditary monarchy-not-by-kings existed after the republic, it had started with Julius Caesar. In this sense Suetonius wrote of The Twelve Caesars, meaning the emperors from Julius Caesar to the Flavians included (where, after Nero, the inherited name had turned into a title), and emperors adopted themselves into an Imperial lineage.

Collapse of the West[link]

By the end of the 3rd century AD, the Roman Empire was split into Western and an Eastern parts, each with its own augustis or caesares. Roman rule had disintegrated somewhat earlier in the century as a result of Germanic invasions which had overrun much of the Western Empire, and imperial authority now ran in the disconnected regions of Italy, Sicily, the Alps, Dalmatia, northwestern Gaul, and what is modern Morocco.^{[citation needed]}

The succession of Western Emperors ended after a set of military coup d'état in Italy during 475 and 476. In 475, Orestes, the Magister militum ("master of soldiers", equivalent to general of the army) in the west, revolted against Emperor Julius Nepos and seized the Italian Peninsula. Orestes then pronounced his own son, Romulus Augustus, as Emperor. Nepos fled to Dalmatia and continued to have the allegiance of the balance of the Western Empire (essentially northern Gaul, Dalamatia, and Morocco) and the backing of the Eastern Empire authorities. Orestes was never able to consolidate power beyond Italy, or gain the Eastern Emperor's recognition for his son's ascension, and when he failed to make good on his promises to the Foederati (foreign mercenaries), they rose up against him. Less than a year after his proclamation, Romulus Augustus was deposed by the German Odoacer, leader of the Foederati. Although he had the strong support of the Senate and enjoyed good relations with the Pope, Odoacer refrained from taking the imperial title and ruled in Nepos' name during the remaining four years of the later's life. Nevertheless he was de facto an autonomous king, and his ascension is generally used by historian to mark the end of Antiquity and the beginning of the Early Middle Ages, also known as the Dark Ages. Upon Nepos' death in 480, Odoacer pursued his assassins, expanding his rule to include Dalmatia as a consequence. Emperor Zeno, with the support of the Roman Senate officially abolished the separate Western Empire at this time and thereafter the unitary empire was ruled from the eastern capitol of Constantinople.^{[citation needed]}

The Roman Empire survived in the east until 1453, but the marginalization of the former heartland of Italy to the empire would have profound cultural impacts on the empire and the position of emperor. In 620, the official language was changed from Latin to Greek, and although the Greek-speaking inhabitants were Romaioi (Ῥωμαῖοι), and were still considered Romans by themselves and the populations of Eastern Europe, the Near East, India, and China, many in Western Europe began to refer to the political entity as the "Greek Empire". The evolution of the church in the no-longer imperial city of Rome and the church in the now supreme Constantinople began to follow divergent paths culminating in the split between the Roman Catholic and Eastern Orthodox faiths. The position of emperor was increasingly influenced by Near Eastern concepts of kingship. Starting with Emperor Heraclius, Roman emperors styled themselves "King of Kings" (form the imperial Persian "Shananshah") from 627 and "Basileus" (from the title used by Alexander the Great) from 629. The later period of the empire is today called the Byzantine Empire as a matter of scholarly convention.^{[citation needed]}

Post-classical assertions to the title[link]

Survival of the Roman Empire in the East[link]

Imaginary portrait of Constantine XI, the last Roman emperor

The line of Roman emperors in the Eastern Roman Empire continued unbroken until the fall of Constantinople in 1453 under Constantine XI Palaiologos. These emperors eventually normalized the imperial dignity into the modern conception of an emperor, incorporated it into the constitutions of the state, and adopted the aforementioned title Basileus kai autokratōr Rhomaiōn ("Emperor and Autocrat of the Romans"). These emperors ceased to use Latin as the language of state after Heraclius. Historians have customarily treated the state of these later Eastern emperors under the name "Byzantine Empire", though Byzantine is not a term that the Byzantines ever used to describe themselves.

Last Roman emperor[link]

Constantine XI Palaiologos was the last reigning Roman emperor. A member of the Palaiologos dynasty, he ruled the feeble remnant of the Eastern Roman Empire from 1449 until his death in 1453 defending its capital Constantinople.

He was born in Mystra^[7] as the eighth of ten children of Manuel II Palaiologos and Helena Dragaš, the daughter of the Serbian prince Constantine Dragaš of Kumanovo. He spent most of his childhood in Constantinople under the supervision of his parents. During the absence of his older brother in Italy, Constantine was regent in Constantinople from 1437-1440.

Before the beginning of the siege, Mehmed II made an offer to Constantine XI. In exchange for the surrender of Constantinople, the emperor's life would be spared and he would continue to rule in Mystra. Constantine refused this offer. Instead he led the defense of the city and took an active part in the fighting along the land walls. At the same time, he used his diplomatic skills to maintain the necessary unity between the Genovese, Venetian, and Byzantine troops. As the city fell on May 29, 1453, Constantine is said to have remarked: "The city is fallen but I am alive." Realizing that the end had come, he reportedly discarded his purple cloak and led his remaining soldiers into a final charge, in which he was killed. With his death, Roman imperial succession came to an end, almost 1500 years after Augustus.

After the fall of Constantinople, Thomas Palaiologos, brother of Constantine XI, was elected emperor and tried to organize the remaining forces. His rule came to an end after the fall of the last major Byzantine city, Corinth. He then moved in Italy and continued to be recognized as Eastern emperor by the Christian powers.

His son Andreas Palaiologos continued claims on the Byzantine throne until he sold the title to Ferdinand of Aragon and Isabella of Castile, the grandparents of Holy Roman Emperor Charles V.

New Western lineage[link]

Charles V was the last man to be crowned Roman Emperor and to celebrate triumph in Rome

The concept of the Roman Empire was renewed in the West with the coronation of the king of the Franks, Charlemagne, as Roman emperor by the Pope on Christmas Day, 800. This line of Roman emperors was actually generally Germanic rather than Roman, but maintained their Roman-ness as a matter of principle. These emperors used a variety of titles (most frequently "Imperator Augustus") before finally settling on Imperator Romanus Electus ("Elected Roman Emperor"). Historians customarily assign them the title "Holy Roman Emperor", which has a basis in actual historical usage, and treat their "Holy Roman Empire" as a separate institution. To Latin Christians of the time, the Pope was the temporal authority as well as spiritual authority, and as Bishop of Rome he was recognized as having the power to anoint or crown a new Roman emperor.

The title of "Western Roman emperor" was further legitimized when the Eastern Roman emperor at Constantinople recognized Charlemagne as Basileus of the West. The last man to hold the title of proper Roman emperor and to be crowned by the pope (although in Bologna, not Rome) was Charles V. All his successors bore only a title of "emperor-elect". Charles V was also the last man to celebrate a triumph in Rome.

The line of "emperor-elect" rulers lasted until 1806 when Francis II dissolved the Empire during the Napoleonic Wars. Despite the existence of later potentates styling themselves "emperor", such as the Napoleons, the Habsburg Emperors of Austria, and the Hohenzollern heads of the German Reich, this marked the end of the Western Empire. Although there is a living heir to the Habsburg dynasty, as well as a Pope and pretenders to the positions of the electors, and although all the medieval coronation regalia are still preserved in Austria, the legal abolition of all aristocratic prerogatives of the former electors and the imposition of republican constitutions in Germany and Austria removed the potential for a revival of the Holy Roman Empire.

Titles and positions[link]

Although these are the most common offices, titles, and positions, one should note that not all Roman emperors used them, nor were all of them used at the same time in history. The consular and censorial offices especially were not an integral part of the Imperial dignity, and were usually held by persons other than the reigning emperor.

• Augustus (also "Αὔγουστος" or "Σεβαστός"), "Majestic" or "Venerable"; an honorific cognomen exclusive to the emperor
• Αὐτοκράτωρ, Autokrator (lit. "Self-ruler"); Greek title equivalent to imperator i.e. Commander-in-Chief
• Βασιλεύς (Basileus), Greek for King, popularly used in the east to refer to the emperor; a formal title of the Roman emperor beginning with Heraclius
• Caesar (also "Καίσαρ" or "Nobilissimus Caesar"), "Caesar" or "Most Noble Caesar"; initially the mere cognomen of a single individual, it was transformed into a title; an honorific name later used to identify an emperor-designate;
• Censor, a Republican office with a five year term and one coequal officeholder; the censor could audit all other magistrates and all state finances
• Consul, the highest magistracy of the Roman Republic with a one year term and one coequal officeholder; the consul was the head of government within Rome and the automatic commander-in-chief of the army outside Rome
• Dominus ("Lord" or "Master"), an honorific title popular in the Empire's middle history
• Imperator ("Commander" or "Commander-in-Chief"), a victory title taken on accession to the purple and after a major military victory; the praenomen of most Roman emperors
• Imperator Destinatus ("Destined to be Emperor"), heir apparent, used by Septimius Severus for Caracalla.
• Imperium maius ("greater imperium") absolute power to a degree greater than any other, including power of enacting capital punishment
• Invictus ("Unconquered"), an honorific title
• Pater Patriae ("Father of the Fatherland"), an honorific title
• Pius Felix ("Pious and Blessed"), an honorific title
• Pontifex Maximus ("Supreme Pontiff" or "Chief Priest", literally "Greatest Bridgemaker"), a title and office of Republican origin, which could not be used by "Catholic" emperors, while by that time only the Pope had a claim on the title of highest religious authority.
• Princeps ("First Citizen" or "Leading Citizen"), an honorific title denoting the status of the emperor as first among equals
• Princeps Iuventutis ("Prince of Youth"), an honorific title awarded to a presumptive emperor-designate
• Princeps Senatus ("First Man of the Senate"), a Republican office with a five year term
• Tribunitia potestas, "tribunician power"; the powers of a tribune of the people, including sacrosanctity and inviolability of his person, and the veto over any decision by any other magistrate, assembly, or the Senate (the emperor could not be a "tribune" because a tribune was a plebeian by definition, therefore the emperor had all the powers of a tribune without actually being one)

Powers[link]

When Augustus established the Princeps, he turned down supreme authority in exchange for a collection of various powers and offices, which in itself was a demonstration of his auctoritas ("authority"). As holding princeps senatus, the emperor declared the opening and closure of each Senate session, declared the Senate's agenda, imposed rules and regulation for the Senate to follow, and met with foreign ambassadors in the name of the Senate. Being pontifex maximus made the emperor the chief administrator of religious affairs, granting him the power to conduct all religious ceremonies, consecrate temples, control the Roman calendar (adding or removing days as needed), appoint the vestal virgins and some flamens, lead the Collegium Pontificum, and summarize the dogma of the Roman religion.

While these powers granted the emperor a great deal of personal pride and influence, they did not include legal authority. In 23 BC, Augustus gave the emperorship its legal power. The first was Tribunicia Potestas, or the powers of the tribune of the plebs without actually holding the office (which would have been impossible, since a tribune was by definition a plebeian, whereas the emperor was by definition a patrician). This endowed the emperor with inviolability (sacrosanctity) of his person, and the ability to pardon any civilian for any act, criminal or otherwise. By holding the powers of the tribune, the emperor could prosecute anyone who interfered with the performance of his duties. The emperor's tribuneship granted him the right to convene the Senate at his will and lay proposals before it, as well as the ability to veto any act or proposal by any magistrate, including the actual tribune of the plebeians. Also, as holder of the tribune's power, the emperor would convoke the Council of the People, lay legislation before it, and served as the council's president. But his tribuneship only granted him power within Rome itself. He would need another power to veto the act of governors and that of the consuls while in the provinces.

To solve this problem, Augustus managed to have the emperor be given the right to hold two types of imperium. The first being consular imperium while he was in Rome, and imperium maius outside of Rome. While inside the walls of Rome, the reigning consuls and the emperor held equal authority, each being able to veto each other's proposals and acts, with the emperor holding all of the consul's powers. But outside of Rome, the emperor outranked the consuls and could veto them without the same effects on himself. Imperium Maius also granted the emperor authority over all the provincial governors, making him the ultimate authority in provincial matters and gave him the supreme command of all of Rome's legions. With Imperium Maius, the emperor was also granted the power to appoint governors of imperial provinces without the interference of the Senate. Also, Imperium Maius granted the emperor the right to veto the governors of the provinces and even the reigning consul while in the provinces.

Lineages and epochs[link]

In the listings of Roman emperors below, the common name is given first, followed by the more formal name adopted upon accession to the purple, the name given at birth, and the years of his reign. So-called victory titles and other titles not forming an integral part of the name (Pontifex Maximus, Princeps Senatus, Pater Patriae, &c.) are not listed. Co-emperors are listed in inferior text, along with notes identifying senior emperors who had hitherto served as co-emperors. Following abbreviations are used:

Principate[link]

The nature of the imperial office and the Principate was established under Julius Caesar's heir and posthumously adopted son, Caesar Augustus, and his own heirs, the descendants of his wife Livia from her first marriage to a scion of the distinguished Claudian clan. This Julio-Claudian dynasty came to an end when the Emperor Nero— a great-great-grandson of Augustus through his daughter and of Livia through her son—was deposed in 68.

Nero was followed by a succession of usurpers throughout 69, commonly called the "Year of the Four Emperors". The last of these, Vespasian, established his own Flavian dynasty. Nerva, who replaced the last Flavian emperor, Vespasian's son Domitian, in 96, was elderly and childless, and chose therefore to adopt an heir, Trajan, from outside his family. When Trajan acceded to the purple he chose to follow his predecessor's example, adopting Hadrian as his own heir, and the practice then became the customary manner of imperial succession for the next century, producing the "Five Good Emperors" and the Empire's period of greatest stability.

The last of the Good Emperors, Marcus Aurelius, chose his natural son Commodus as his successor rather than adopting an heir. Commodus's misrule led to his murder on 31 December 192, following which a brief period of instability quickly gave way to Septimius Severus, who established the Severan dynasty which, except for an interruption in 217-218, held the purple until 235.

Crisis of the Third Century[link]

The accession of Maximinus Thrax marks both the close and the opening of an era. It was one of the last attempts by the increasingly impotent Roman Senate to influence the succession. Yet it was the second time that a man had achieved the purple while owing his advancement purely to his military career; both Vespasian and Septimius Severus had come from noble or middle class families, while Thrax was born a commoner. He never visited the city of Rome during his reign, which marks the beginning of a series of "barracks emperors" who came from the army. Between 235 and 285 over a dozen emperors achieved the purple, but only Valerian and Carus managed to secure their own sons' succession to the throne; both dynasties died out within two generations.

Dominate[link]

The accession to the purple on 20 November 284, of Diocletian, the lower-class, Greek-speaking Dalmatian commander of Carus's and Numerian's household cavalry (protectores domestici), marked a major departure from traditional Roman constitutional theory regarding the emperor, who was nominally first among equals; Diocletian introduced oriental despotism into the imperial dignity. Whereas before emperors had worn only a purple toga (toga purpura) and been greeted with deference, Diocletian wore jewelled robes and shoes, and required those who greeted him to kneel (proskynesis) and kiss the hem of his robe (adoratio). In many ways, Diocletian was the first monarchical emperor, and this is symbolised by the fact that the word dominus ("Lord") rapidly replaced princeps as the favoured word for referring to the emperor. Significantly, neither Diocletian nor his co-emperor, Maximian, spent much time in Rome after 286, establishing their imperial capitals at Nicomedia and Mediolanum (modern Milan), respectively.

Diocletian established the Tetrarchy, a system by which the Roman Empire was divided into East and West, with each having an Augustus to rule over it and a Caesar to assist him. The Tetrarchy ultimately degenerated into civil war, but the eventual victor, Constantine the Great, restored Diocletian's system of dividing the Empire into East and West. He kept the East for himself and founded his city of Constantinople as its new capital.

The dynasty Constantine established was also soon swallowed up in civil war and court intrigue until it was replaced, briefly, by Julian the Apostate's general Jovian and then, more permanently, by Valentinian I and the dynasty he founded in 364. Though he was a soldier from a low middle class background, Valentinian was not a barracks emperor; he was elevated to the purple by a conclave of senior generals and civil officials.

Late empire[link]

Theodosius I acceded to the purple in the East in 379 and in the West in 394. He outlawed paganism and made Christianity the Empire's official religion. He was the last emperor to rule over a united Roman Empire; the distribution of the East to his son Arcadius and the West to his son Honorius after his death in 395 represented a permanent division.

In the West, the office of emperor soon degenerated into being little more than a puppet of a succession of Germanic tribal kings, until finally the Heruli Odoacer simply overthrew the child-emperor Romulus Augustulus in 476, shipped the imperial regalia to the Emperor Zeno in Constantinople and became King of Italy. Though during his own lifetime Odoacer maintained the legal fiction that he was actually ruling Italy as the viceroy of Zeno, historians mark 476 as the traditional date of the fall of the Roman Empire in the West. Large parts of Italy (Sicily, the south part of the peninsula, Ravenna, Venice etc.), however, remained under actual imperial rule from Constantinople for centuries, with imperial control slipping or becoming nominal only as late as the 11th century. In the East, the Empire continued until the fall of Constantinople to the Ottoman Turks in 1453. Although known as the Byzantine Empire by contemporary historians, the Empire was simply known as the Roman Empire to its citizens and neighboring countries.
