The following is a list of usurpers in the Roman Empire. For an overview of the problem and consequences of usurpation, see Roman usurpers. In the Byzantine Empire (476–1453), rebellion and usurpation were so notoriously frequent (in the vision of the medieval West, where usurpation was rare) that the term "byzantine" became a byword for political intrigue and conspiracy. For usurpation in the Byzantine Empire, see List of Byzantine usurpers.

Usurpers not considered legitimate emperors
editThe following 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.
Name | Against | 'Reign' | Notes |
---|---|---|---|
Lucius Arruntius Camillus Scribonianus | Claudius | 41 AD | The imperial legate of Dalmatia under Caligula, he was considered a possible successor and attempted to claim the throne. He committed suicide after his troops abandoned him. |
Nymphidius Sabinus | Galba | 68 AD | Nero's Praetorian Prefect, declared himself emperor after Nero's suicide, claiming he was the illegitimate son of Caligula. Killed by the Praetorian Guard as Galba approached Rome. |
Terentius Maximus | Titus | c. 79 AD | Due to his resemblance to the former emperor, he claimed to be Nero, and gained followers in Asia Minor and along his march to the Euphrates . He took refuge with Artabanus III of Parthia, but was executed when his true identity became known. |
Lucius Antonius Saturninus | Domitian | 89 AD | Motivated by a personal grudge, Saturninus led two legions stationed at Moguntiacum (Mainz) in revolt against Domitian. He was defeated by the general and future emperor Trajan, and later executed. |
Avidius Cassius | Marcus Aurelius | 175 | governor of Syria, declared himself emperor upon hearing erroneus reports that Marcus Aurelius had died, and continued his revolt even upon learning Marcus Aurelius was alive.

Pescennius Niger CAESAR GAIVS PESCENNIVS NIGER IVSTVS AVGVSTVS |
Didius Julianus, Septimius Severus | 193–194 | Proclaimed emperor by the Eastern legions after the murder of Pertinax. Defeated in battle by Severus's forces, and captured and executed while attempting to flee to Parthia. |

Didius Julianus, Septimius Severus | 193–197 | Proclaimed emperor by the British and Spanish legions after the murder of Pertinax. Allied to Severus during the initial conflict with Pescennius Niger. Severus then moved to secure complete control of the empire, and defeated Albinus in battle, who was either killed in battle, or executed afterwards. |
Verus |
Elagabalus | 218–219 | A former centurion who had risen to the rank of senator and to command of the Legio III Gallicain in Syria. His legion had supported Elagabalus's bid for power, but then grew disenchanted with the emperor; Verus took the opportunity to declare himself emperor and led the legion in rebellion. However, Elagabalus ordered the execution of Verus (in unclear circumstances), and dispersed the rebellious legion, ending the revolt. |
Gellius Maximus | Elagabalus | 219 | An officer in Legio IV Scythica in Syria who also took advantage of the turmoil during the Elagabalus's reign to proclaim himself emperor. The rebellion was soon extinguished, and Gellius Maximus was executed. |

Gallienus | 260–269 | A general in the Western provinces, who defeated a Juthungian invasion and was then proclaimed emperor by his troops. Led the breakaway 'Gallic Empire' for most of a decade, and indeed outlived Gallienus. However, he was then himself challenged by a usurper, and although he defeated Laelianus, he was subsequently murdered by his troops when he refused to let them sack Mogantiacum |
Ingenuus | Gallienus | 260 | The legate in Pannonia, declared himself emperor after the defeat and capture of Valerian. Was defeated in battle by Gallienus's general Aureolus and comitted suicide. |
Regalianus | Gallienus | 260 | A military office in Pannonia, who was declared emperor after the defeat of Ingenuus. Was later killed by his own men in collusion with Sarmatian invaders. |

Aureolus | Gallienus | 268 | A major commander of Gallienus's armies, who eventually turned against him. He tried to persuade Postumus to attack Italy and depose Gallienus, but Postumus seems to have been unreceptive. Once his treachery was exposed, Aureolus claimed the throne himself, but was attacked and defeated by Gallienus who then besieged him in Milan. However, during the siege Gallienus was murdered in a conspiracy led by Claudius Gothicus, who then became emperor. |
Laelianus | Claudius Gothicus/ Postumus |
269 | A military commander in Germania Superior under Postumus, he was proclaimed emperor by his troops, in opposition to Postumus as leader of the Gallic Empire.

Domitianus II | Aurelian | 271 | An individual known to have claimed the throne from coins struck with his name, but otherwise mysterious. Possibly claimed the throne of the Gallic Empire after the death of Victorinus. Fate unknown, but the scarcity of coins suggests he did not reign for long. |
Tetricus I with Tetricus II |
Aurelian | 271–274 | The governor of a province in Gaul, he was declared emperor at the behest of Victorinus's mother, after her son's death. He eventually negotiated to surrender the Gallic Empire to Aurelian, thus reuniting the empire, and was allowed to keep his senatorial rank. |
Septimius | Aurelian | 271–274 | Proclaimed emperor in Dalmatia when a Gothic invasion was threatened, but was killed by his own troops when the invasion failed to materialise. |

Possible usurpers
editSeveral histories contain details of other supposed usurpers, but there is little or no supporting evidence that these individuals existed or attempted usurpation.
Name | Against | 'Reign' | Notes |
---|---|---|---|
Uranius | Elagabalus/Alexander Severus/Valerian | ? | There is significant confusion regarding Uranius. Polemius Silvius claims he was a usurper during the reign of Elagabalus, while [Zosimus]] has him as a usurper in the reign of Alexander Severus. It is possible that both authors have confused the details of an apparent later usurper. Coins bearing the name Lucius Julius Aurelius Sulpicius Severus Uranius Antoninus were minted in Syria in 254, suggesting that the actual act of usurpation took place in the reign of Valerian. |
Taurinus | Elagabalus/Alexander Severus | c. 232 | According to Aurelius Victor he was a usurper in the reign of Alexander Severus, but Polemius Silvius has him as another usurper during the reign of Elagabalus. |
Seleucus | Elagabalus | c. 221 | Attested by the 5th-century historian Polemius Silvius, but nowhere else. His identity is not clear: he could be Julius Antonius Seleucus, governor in Moesia, or Marcus Flavius Vitellius Seleucus, consul for 221. |
Sallustius | Alexander Severus | 227 | The father-in-law of Alexander Severus, who raised him to the rank of Caesar (i.e. junior emperor). According to Polemius Silvius he attempted to usurp the throne by killing Alexander, but failed and was executed instead. However, according to Herodian, Alexander's mother had Sallustius killed for other reasons. |
Taurinus | Alexander Severus | c. 232 | According to Aurelius Victor he was a usurper in the reign of Alexander Severus, but Polemius Silvius has him as another usurper during the reign of Elagabalus. |
Quartinus | Maximinus Thrax | 235 | Only attested by Herodian, who suggests that he was proclaimed emperor by troops in the East, but then betrayed and executed by one of the officers involved. |
Silbannacus | Philip the Arab | Known only from coin finds, bearing the title IMP MAR SILBANNACVS AVG, dated to the Philip's reign. | |
Sponsianus | Philip the Arab | Also known only from coin finds, but there is some evidence the coins are modern forgeries. | |
Censorinus | Claudius Gothicus | 269–270 | Only attested by the Historia Augusta, and probably fictious. |
Urbanus | Aurelian | 271 | Only attested by Zosimus, and possibly fictious. |
Firmus | Aurelian | 271 | Only attested by the Historia Augusta, and although probably a real person, does not seem to have actually claimed the throne. |
The Thirty Tyrants
editThe Thirty Tyrants (Latin: Tyranni Triginta) were a series of thirty rulers that appear in the Historia Augusta as alleged usurpers to the throne of the Roman Empire during the reign of the emperor Gallienus. The Historia Augusta is unreliable, and there is a scholarly consensus that the author deliberately inflated the number of pretenders in order to parallel the Thirty Tyrants of Athens. The source actually gives 32 names but as the author places the last two under the reign of Maximinus Thrax and Claudius II respectively, this leaves thirty pretenders supposedly under the reign of Gallienus.
