The Roman emperors were the rulers of the Roman Empire from the granting of the name and title Augustus to Octavian by the Roman Senate in 27 BC onward.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory. Augustus maintained a facade of Republican rule, rejecting monarchical titles but calling himself princeps senatus (first man of the Senate) and princeps civitatis (first citizen of the state). The title of Augustus was conferred on his successors to the imperial position, and emperors gradually grew more monarchical and authoritarian.Lua error: not enough memory.Lua error: not enough memory.

The style of government instituted by Augustus is called the Principate and continued until the late third or early fourth century.Lua error: not enough memory.Lua error: not enough memory. The modern word "emperor" derives from the title imperator, that was granted by an army to a successful general; during the initial phase of the empire, the title was generally used only by the princeps.Lua error: not enough memory.Lua error: not enough memory. For example, Augustus's official name was Imperator Caesar Divi Filius Augustus.Lua error: not enough memory.Lua error: not enough memory. The territory under command of the emperor had developed under the period of the Roman Republic as it invaded and occupied much of Europe and portions of North Africa and the Middle East. Under the republic, the Senate and People of Rome authorized provincial governors, who answered only to them, to rule regions of the empire.Lua error: not enough memory.Lua error: not enough memory. The chief magistrates of the republic were two consuls elected each year; consuls continued to be elected in the imperial period, but their authority was subservient to that of the emperor, who also controlled and determined their election.Lua error: not enough memory.Lua error: not enough memory. Often, the emperors themselves, or close family, were selected as consul.Lua error: not enough memory.Lua error: not enough memory.

After the Crisis of the Third Century, Diocletian increased the authority of the emperor and adopted the title "dominus noster" (our lord). The rise of powerful barbarian tribes along the borders of the empire, the challenge they posed to the defense of far-flung borders as well as an unstable imperial succession led Diocletian to divide the administration of the Empire geographically with a co-augustus in 286. In 330, Constantine the Great, the emperor who accepted Christianity, established a second capital in Byzantium, which he renamed Constantinople. Historians consider the Dominate period of the empire to have begun with either Diocletian or Constantine, depending on the author.Lua error: not enough memory.Lua error: not enough memory. For most of the period from 286 to 480, there was more than one recognized senior emperor, with the division usually based on geographic regions. This division was consistently in place after the death of Theodosius I in 395, which historians have dated as the division between the Western Roman Empire and the Eastern Roman Empire. However, formally the Empire remained a single polity, with separate co-emperors in the separate courts.Lua error: not enough memory.Lua error: not enough memory.

The fall of the Western Roman Empire is dated either from the de facto date of 476, when Romulus Augustulus was deposed by the Germanic Herulians led by Odoacer, or the de jure date of 480, on the death of Julius Nepos, when Eastern emperor Zeno ended recognition of a separate Western court.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory. Historians typically refer to the empire in the centuries that followed as the "Byzantine Empire", oriented toward Hellenic culture and governed by the Byzantine emperors.[lower-alpha 1] Given that "Byzantine" is a later historiographical designation and the inhabitants and emperors of the empire continually maintained Roman identity, this designation is not used universally and continues to be a subject of specialist debate.[lower-alpha 2] Under Justinian I, in the sixth century, a large portion of the western empire was retaken, including Italy, Africa, and part of Spain.Lua error: not enough memory.Lua error: not enough memory. Over the course of the centuries thereafter, most of the imperial territories were lost, which eventually restricted the empire to Anatolia and the Balkans.[lower-alpha 3] The line of emperors continued until the death of Constantine XI Palaiologos at the fall of Constantinople in 1453, when the remaining territories were conquered by the Ottoman Turks led by Sultan Mehmed II.Lua error: not enough memory.Lua error: not enough memory.[lower-alpha 4] In the aftermath of the conquest, Mehmed II proclaimed himself kayser-i Rûm ("Caesar of the Romans"),[lower-alpha 5] thus claiming to be the new emperor,Lua error: not enough memory.Lua error: not enough memory. a claim maintained by succeeding sultans.Lua error: not enough memory.Lua error: not enough memory.

While the imperial government of the Roman Empire was rarely called into question during its five centuries in the west and fifteen centuries in the east, individual emperors often faced unending challenges in the form of usurpation and perpetual civil wars.Lua error: not enough memory.Lua error: not enough memory. From the rise of Augustus, the first Roman emperor, in 27 BC to the sack of Rome in AD 455, there were over a hundred usurpations or attempted usurpations (an average of one usurpation or attempt about every four years). From the murder of Commodus in 192 until the fifth century, there was scarcely a single decade without succession conflicts and civil war. Very few emperors died of natural causes, with regicide in practical terms having become the expected end of a Roman emperor by late antiquity.Lua error: not enough memory.Lua error: not enough memory. The distinction between a usurper and a legitimate emperor is a blurry one, given that a large number of emperors commonly considered legitimate began their rule as usurpers, revolting against the previous legitimate emperor.Lua error: not enough memory.Lua error: not enough memory.

True legitimizing structures and theories were weak, or wholly absent, in the Roman Empire,Lua error: not enough memory.Lua error: not enough memory. and there were no true objective legal criteria for being acclaimed emperor beyond acceptance by the Roman army.Lua error: not enough memory.Lua error: not enough memory. Dynastic succession was not legally formalized, but also not uncommon, with powerful rulers sometimes succeeding in passing power on to their children or other relatives. While dynastic ties could bring someone to the throne, they were not a guarantee that their rule would not be challenged.Lua error: not enough memory.Lua error: not enough memory. With the exception of Titus (r.79–81; son of Vespasian), no son of an emperor who ruled after the death of his father died a natural death until Constantine I in 337. Control of Rome itself and approval of the Roman Senate held some importance as legitimising factors, but were mostly symbolic. Emperors who began their careers as usurpers had often been deemed public enemies by the senate before they managed to take the city. Emperors did not need to be acclaimed or crowned in Rome itself, as demonstrated in the Year of the Four Emperors (69), when claimants were crowned by armies in the Roman provinces, and the senate's role in legitimising emperors had almost faded into insignificance by the Crisis of the Third Century (235–285). By the end of the third century, Rome's importance was mainly ideological, with several emperors and usurpers even beginning to place their court in other cities in the empire, closer to the imperial frontier.Lua error: not enough memory.Lua error: not enough memory.

Common methods used by emperors to assert claims of legitimacy, such as proclamation by the army, blood connections (sometimes fictitious) to past emperors, wearing imperial regalia, 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.Lua error: not enough memory.Lua error: not enough memory. There were no constitutional or legal distinctions that differentiated legitimate emperors and usurpers. In ancient Roman texts, the differences between emperors and "tyrants" (the term typically used for usurpers) is often a moral one (with the tyrants ascribed wicked behaviour) rather than a legal one. Typically, the actual distinction was whether the claimant had been victorious or not. In the Historia Augusta, an ancient Roman collection of imperial biographies, the usurper Pescennius Niger (193–194) is expressly noted to only be a tyrant because he was defeated by Septimius Severus (r.193–211).Lua error: not enough memory.Lua error: not enough memory. This is also followed in modern historiography, where, in the absence of constitutional criteria separating them, the main factor that distinguishes usurpers from legitimate Roman emperors is their degree of success. What makes a figure who began as a usurper into a legitimate emperor is typically either that they managed to gain the recognition from a more senior, legitimate, emperor, or that they managed to defeat a more senior, legitimate emperor and seize power from them by force.Lua error: not enough memory.Lua error: not enough memory.

List inclusion criteria

Given that a concept of constitutional legitimacy was irrelevant in the Roman Empire, and emperors were only 'legitimate' in so far as they were able to be accepted in the wider empire,Lua error: not enough memory.Lua error: not enough memory. this list of emperors operates on a collection of inclusion criteria:

  • Imperial claimants whose power across the empire became, or from the beginning was, absolute and who ruled undisputed are treated as legitimate emperors.Lua error: not enough memory.Lua error: not enough memory. From 286 onward, when imperial power was usually divided among two colleagues in the east and west,Lua error: not enough memory.Lua error: not enough memory. control over the respective half is sufficient even if a claimant was not recognized in the other half, such as was the case for several of the last few emperors in the west.Lua error: not enough memory.Lua error: not enough memory.
  • Imperial claimants who were proclaimed emperors by another, legitimate, senior emperor, or who were recognized by a legitimate senior emperor, are treated as legitimate emperors.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory. Many emperors ruled alongside one or various joint-emperors. However, and specially from the 4th century onwards, most of these were children who never ruled in their own right. Scholars of the later Empire always omit these rulers,Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory. but the same is not always applied during the early Empire.Lua error: not enough memory. For the purposes of consistency, later senior emperors' tenures as co-emperors are not counted as part of their reign. The list also gives all co-emperors their own entry only up to the 4th century.
  • Imperial claimants who achieved the recognition of the Roman Senate, especially in times of uncertainty and civil war, are, due to the senate's nominal role as an elective body, treated as legitimate emperors.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory. In later times, especially when emperors ruled from other cities, this criterion defaults to the possession and control of Rome itself. In the later eastern empire, possession of the capital of Constantinople was an essential element of imperial legitimacy.Lua error: not enough memory.Lua error: not enough memory.

In the case of non-dynastic emperors after or in the middle of the rule of a dynasty, it is customary among historians to group them together with the rulers of said dynasty,Lua error: not enough memory.Lua error: not enough memory. an approach that is followed in this list. Dynastic breaks with non-dynastic rulers are indicated with thickened horizontal lines.

Other claims to the Roman imperial title
Subject Description
Roman usurpers (list) Roman usurpers were individuals or groups of individuals who obtained or tried to obtain power by force and without legitimate legal authority. Usurpation was endemic during the Roman imperial era, especially from the crisis of the third century onwards, when political instability became the rule.

A number of individuals proclaimed themselves emperor (or were proclaimed or appointed as emperor), but are not considered as legitimate emperors because they did not oust the ruling emperor, or did not establish control of the whole empire, or were not accepted by the senate or other imperial colleagues.

Byzantine usurpers (list)
Holy Roman Emperors (list) The Holy Roman Emperor was the ruler and head of state of the Holy Roman Empire.

Charlemagne was crowned imperator romanorum ("Emperor of the Romans") by Pope Leo III in AD 800. In so doing, the Pope rejected the legitimacy of Empress Irene.Lua error: not enough memory.Lua error: not enough memory. The Byzantines never recognized the Holy Roman emperors as "Roman emperors" and called them the 'emperor (or king) of the Franks', to them only the Byzantine Senate (successor to the Roman Senate) and/or the Byzantine military (successor to the Roman military) had the right to appoint a new Roman Emperor. Likewise, Western Europeans didn't recognize the legitimacy of the Byzantine emperors and called them the 'emperor of the Greeks' or the 'emperor of Constantinople'. See also: Problem of two emperors

Latin Emperors (list) The Latin Emperor was the ruler of the Latin Empire, the historiographical convention for the Crusader realm, established in Constantinople after the Fourth Crusade (1204) and lasting until the city was recovered by the Byzantine Greeks in 1261. Its name derives from its Catholic and Western European ("Latin") nature. The empire, whose official name was Imperium Romaniae (Latin: "Empire of Romania"), claimed the direct heritage of the Eastern Roman Empire, which had most of its lands taken and partitioned by the crusaders. This claim however was disputed by the Byzantine Greek successor states, the Empire of Nicaea, the Empire of Trebizond and the Despotate of Epirus. Out of these three, the Nicaeans succeeded in displacing the Latin emperors in 1261 and restored the Byzantine Empire.
Trapezuntine emperors (list) The Trapezuntine emperors were the rulers of the Empire of Trebizond, one of the successor states of the Byzantine Empire founded after the Fourth Crusade in 1204, until its fall to the Ottoman Empire in 1461. The rulers of Trebizond called themselves Megas Komnenos and – like their counterparts in the other two Byzantine successor states, the Empire of Nicaea and the Despotate of Epirus – initially claimed supremacy as "Emperor and Autocrat of the Romans". However, after Michael VIII Palaiologos of Nicaea recaptured Constantinople in 1261, the Komnenian use of the style "Emperor" became a sore point. In September 1282, at Constantinople, John II of Trebizond relinquished his claim and accepted the title despot. His successors used a variant of the imperial title, "Emperor and Autocrat of all the East, the Iberians, and the Transmarine Provinces" until the Empire's end in 1461.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory.Lua error: not enough memory.
Emperors of Thessalonica (list) The emperors of Thessalonica were the rulers of the Empire of Thessalonica, a historiographic term to refer to the short-lived state centred on the city of Thessalonica between 1224 and 1246 (sensu stricto until 1242) and ruled by the Komnenodoukas of Epirus.
Despots of Epirus (list) The despot of Epirus was the ruler of the Despotate of Epirus, one of the successor states of the Byzantine Empire in the aftermath of the Fourth Crusade. The name "Despotate of Epirus" and the title "despot of Epirus" are modern historiographical names, and were not in use by the despots themselves.

Some rulers used the version "despot of Romania" (Romania essentially referring to the territories of the Roman Empire, i.e. Byzantium) or "despot of the Romans" (claiming rulership over the Romans, i.e. the Byzantines/Greeks).

Ottoman sultans (list) Based on the concept of right of conquest, the sultans of the Ottoman Empire claimed to be the legitimate Roman Emperors, in succession to the Byzantine emperors who had previously ruled from Constantinople. This claim was recognized by the Islamic world, but was never recognized by the Western Europeans. See Ottoman claim to Roman succession
