List of Roman civil wars and revolts

The First Servile War of 135–132 BC was a slave rebellion against the Roman Republic, which took place in Sicily. The revolt started in 135 when Eunus, a slave from Syria who claimed to be a prophet, captured the city of Enna in the middle of the island with 400 fellow slaves. Soon after, Cleon, a Cilician slave, stormed the city of Agrigentum on the southern coast, slaughtered the population, and then joined Eunus' army and became his military commander. Eunus even proclaimed himself king, under the name of Antiochus, after the Seleucid emperors of his native Syria.

Gaius Marius was a Roman general and statesman. Victor of the Cimbric and Jugurthine wars, he held the office of consul an unprecedented seven times. He was also noted for his important reforms of Roman armies. He set the precedent for the shift from the militia levies of the middle Republic to the professional soldiery of the late Republic; he also improved the pilum, a javelin, and made large-scale changes to the logistical structure of the Roman army.

Hispania was the Roman name for the Iberian Peninsula and its provinces. Under the Roman Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Hispania Tarraconensis. Subsequently, the western part of Tarraconensis was split off, first as Hispania Nova, later renamed "Callaecia". From Diocletian's Tetrarchy onwards, the south of the remainder of Tarraconensis was again split off as Carthaginensis, and all of the mainland Hispanic provinces, along with the Balearic Islands and the North African province of Mauretania Tingitana, were later grouped into a civil diocese headed by a vicarius. The name Hispania was also used in the period of Visigothic rule.

Lucius Sergius Catilina, known in English as Catiline, was a Roman politician and soldier. He is best known for instigating the Catilinarian conspiracy, a failed attempt to violently seize control of the Roman state in 63 BC.

Ambiorix's revolt was an episode during the Gallic Wars between 54 and 53 BC in which the Eburones tribe, under its leader, Ambiorix, rebelled against the Roman Republic.

The Gallic Wars were waged between 58 and 50 BC by the Roman general Julius Caesar against the peoples of Gaul. Gallic, Germanic, and British tribes fought to defend their homelands against an aggressive Roman campaign. The Wars culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul. Though the Gallic military was as strong as the Romans, the Gallic tribes' internal divisions eased victory for Caesar. Gallic chieftain Vercingetorix's attempt to unite the Gauls under a single banner came too late. Caesar portrayed the invasion as being a preemptive and defensive action, but historians agree that he fought the Wars primarily to boost his political career and to pay off his debts. Still, Gaul was of significant military importance to the Romans. Native tribes in the region, both Gallic and Germanic, had attacked Rome several times. Conquering Gaul allowed Rome to secure the natural border of the river Rhine.

Gaius Julius Caesar was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in a civil war, and subsequently became dictator from 49 BC until his assassination in 44 BC. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire.

Gnaeus Pompeius Magnus, known in English as Pompey or Pompey the Great, was a leading Roman general and statesman. He played a significant role in the transformation of Rome from republic to empire. Early in his career, he was a partisan and protégé of the Roman general and dictator Sulla; later, he became the political ally, and finally the enemy, of Julius Caesar.

The Bellum Batonianum was a military conflict fought in the Roman province of Illyricum in the 1st century AD, in which an alliance of native peoples of the two regions of Illyricum, Dalmatia and Pannonia, revolted against the Romans. The rebellion began among native peoples who had been recruited as auxiliary troops for the Roman army. They were led by Bato the Daesitiate, a chieftain of the Daesitiatae in the central part of present-day Bosnia and Herzegovina, and were later joined by the Breuci, a tribe in Pannonia led by Bato the Breucian. Many other tribes in Illyria also joined the revolt.

Illyricum was a Roman province that existed from 27 BC to sometime during the reign of Vespasian. The province comprised Illyria/Dalmatia in the south and Pannonia in the north. Illyria included the area along the east coast of the Adriatic Sea and its inland mountains, eventually being named Dalmatia. Pannonia included the northern plains that now are a part of Serbia, Croatia and Hungary. The area roughly corresponded to part or all of the territories of today's Albania, Kosovo, Montenegro, Serbia, Bosnia and Herzegovina, Croatia, and Slovenia.

Arminius was a chieftain of the Germanic Cherusci tribe who is best known for commanding an alliance of Germanic tribes at the Battle of the Teutoburg Forest in 9 AD, in which three Roman legions under the command of general Publius Quinctilius Varus were destroyed. His victory at Teutoburg Forest would precipitate the Roman Empire's permanent strategic withdrawal from Germania Magna. Modern historians have regarded Arminius' victory as one of Rome's greatest defeats. As it prevented the Romanization of Germanic peoples east of the Rhine, it has also been considered one of the most decisive battles in history and a turning point in human history.

The Battle of the Teutoburg Forest, described as the Varian Disaster by Roman historians, took place at modern Kalkriese in AD 9, when an alliance of Germanic peoples ambushed Roman legions and their auxiliaries, led by Publius Quinctilius Varus. The alliance was led by Arminius, a Germanic officer of Varus's auxilia. Arminius had acquired Roman citizenship and had received a Roman military education, which enabled him to deceive the Roman commander methodically and anticipate the Roman army's tactical responses.

Germanicus Julius Caesar was an ancient Roman general and politician most famously known for his campaigns in Germania. The son of Nero Claudius Drusus and Antonia the Younger, Germanicus was born into an influential branch of the patrician gens Claudia. The agnomen Germanicus was added to his full name in 9 BC when it was posthumously awarded to his father in honor of his victories in Germania. In AD 4 he was adopted by his paternal uncle Tiberius, who succeeded Augustus as Roman emperor a decade later. As a result, Germanicus became an official member of the gens Julia, another prominent family, to which he was related on his mother's side. His connection to the Julii Caesares was further consolidated through a marriage between himself and Agrippina the Elder, a granddaughter of Augustus. He was also the father of Caligula, the maternal grandfather of Nero, and the older brother of Claudius.

Drusus Julius Caesar was the son of Emperor Tiberius, and heir to the Roman Empire following the death of his adoptive brother Germanicus in AD 19.

The Dii were an independent Thracian tribe, swordsmen, who lived among the foothills of Mount Rhodope in Thrace, and particularly in the east bank of Nestos, from the springs to the Nestos gorge. They often joined the ranks of organized armies as mercenaries or volunteers. Thucydides declared that they were the most warlike infantry in Sitalkes' army.

The Kitos War was one of the major Jewish–Roman wars (66–136). The rebellions erupted in 115, when most of the Roman armies were fighting Trajan's Parthian War on the eastern border of the Roman Empire. Major uprisings by Jews in Cyrenaica, Cyprus and Egypt spiralled out of control, resulting in a widespread slaughter of the remaining Roman garrisons and Roman citizens by Jewish rebels.

In ancient Egyptian religion, Apis or Hapis, alternatively spelled Hapi-ankh, was a sacred bull worshiped in the Memphis region, identified as the son of Hathor, a primary deity in the pantheon of ancient Egypt. Initially, he was assigned a significant role in her worship, being sacrificed and reborn. Later, Apis also served as an intermediary between humans and other powerful deities.

The Bar Kokhba revolt, also known as the Third Jewish Revolt or the 'Jewish Expedition' as the Romans named it, was a rebellion by the Jews of the Roman province of Judea, led by Simon bar Kokhba, against the Roman Empire. The last of the three Jewish-Roman Wars, it was fought c. 132–136 CE.

The Year of the Five Emperors was AD 193, in which five men claimed the title of Roman emperor: Pertinax, Didius Julianus, Pescennius Niger, Clodius Albinus, and Septimius Severus. This year started a period of civil war when multiple rulers vied for the chance to become emperor.

Lucius Septimius Severus was Roman emperor from 193 to 211. He was born in Leptis Magna 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 seized power after the death of the emperor Pertinax in 193 during the Year of the Five Emperors.

Gaius Pescennius Niger was Roman Emperor from 193 to 194 during the Year of the Five Emperors. He claimed the imperial throne in response to the murder of Pertinax and the elevation of Didius Julianus, but was defeated by a rival claimant, Septimius Severus, and killed while attempting to flee from Antioch.

Decimus Clodius Albinus was a Roman imperial pretender between 193 and 197. He was proclaimed emperor by the legions in Britain and Hispania after the murder of Pertinax in 193, and proclaimed himself emperor again in 196, before his final defeat and death the following year.

Commodus was a Roman emperor who ruled from 177 to 192. He served jointly with his father Marcus Aurelius from 177 until the latter's death in 180, and thereafter he reigned alone until his assassination. His reign is commonly thought of as marking the end of a golden age of peace and prosperity in the history of the Roman Empire, known as the Pax Romana.

Marcus Didius Julianus was Roman emperor from March to June 193, during the Year of the Five Emperors. Julianus had a promising political career, governing several provinces, including Dalmatia and Germania Inferior, and defeated the Chauci and Chatti, two invading Germanic tribes. He was even appointed to the consulship in 175 along with Pertinax as a reward, before being demoted by Commodus. After this demotion, his early, promising political career languished.

The Severan dynasty was a Roman imperial dynasty that ruled the Roman Empire between 193 and 235, during the Roman imperial period. The dynasty was founded by the emperor Septimius Severus, who rose to power after the Year of the Five Emperors as the victor of the civil war of 193–197, and his wife, Julia Domna. After the short reigns and assassinations of their two sons, Caracalla and Geta, who succeeded their father in the government of the empire, Julia Domna's relatives themselves assumed power by raising Elagabalus and then Severus Alexander to the imperial office.

The Battle of Antioch was fought between the Roman army of the Emperor Macrinus and his rival Elagabalus, whose troops were commanded by General Gannys, probably a short distance from Antioch. Gannys' victory over Macrinus led to the downfall of the emperor and his replacement by Elagabalus.

Marcus Aurelius Antoninus, better known by his nicknames "Elagabalus" and Heliogabalus, was Roman emperor from 218 to 222, while he was still a teenager. His short reign was conspicuous for sex scandals and religious controversy. A close relative to the Severan dynasty, he came from a prominent Arab family in Emesa (Homs), Syria, where since his early youth he served as head priest of the sun god Elagabal. After the death of his cousin, the emperor Caracalla, Elagabalus was raised to the principate at 14 years of age in an army revolt instigated by his grandmother Julia Maesa against Caracalla's short-lived successor, Macrinus. He only posthumously became known by the Latinised name of his god.

Moesia was an ancient region and later Roman province situated in the Balkans south of the Danube River, which included most of the territory of modern eastern Serbia, Kosovo, north-eastern Albania, northern parts of North Macedonia, Northern Bulgaria, Romanian Dobruja and small parts of Southern Ukraine.

The Crisis of the Third Century, also known as the Military Anarchy or the Imperial Crisis, was a period in which the Roman Empire nearly collapsed. The crisis ended due to the military victories of Aurelian and with the ascension of Diocletian and his implementation of reforms in 284.

The Gallic Empire or the Gallic Roman Empire are names used in modern historiography for a breakaway part of the Roman Empire that functioned de facto as a separate state from 260 to 274. It originated during the Crisis of the Third Century, when a series of Roman military leaders and aristocrats declared themselves emperors and took control of Gaul and adjacent provinces without attempting to conquer Italy or otherwise seize the central Roman administrative apparatus.

The Palmyrene Empire was a short-lived breakaway state from the Roman Empire resulting from the Crisis of the Third Century. Named after its capital city, Palmyra, it encompassed the Roman provinces of Syria Palaestina, Arabia Petraea, and Egypt, as well as large parts of Asia Minor.

Gordian I was Roman emperor for 22 days with his son Gordian II in 238, the Year of the Six Emperors. Caught up in a rebellion against the Emperor Maximinus Thrax, he was defeated by forces loyal to Maximinus, and he committed suicide after the death of his son.

Gordian II was Roman emperor with his father Gordian I in 238 AD, the Year of the Six Emperors. Seeking to overthrow Maximinus Thrax, he died in battle outside Carthage. Since he died before his father, Gordian II had the shortest reign of any Roman emperor, at 22 days.

Marcus Clodius Pupienus Maximus was Roman emperor with Balbinus for 99 days in 238, during the Year of the Six Emperors. The sources for this period are scant, and thus knowledge of the emperor is limited. In most contemporary texts he is referred to by his cognomen "Maximus" rather than by his second nomen Pupienus.

Decimus Caelius Calvinus Balbinus was Roman emperor with Pupienus for three months in 238, the Year of the Six Emperors.

Gordian III was Roman emperor from 238 to 244. At the age of 13, he became the youngest sole emperor of the united Roman Empire. Gordian was the son of Antonia Gordiana and Junius Balbus, who died before 238. Antonia Gordiana was the daughter of Emperor Gordian I and younger sister of Emperor Gordian II. Very little is known of his early life before his acclamation. Gordian had assumed the name of his maternal grandfather in 238.

The Civil Wars of the Tetrarchy were a series of conflicts between the co-emperors of the Roman Empire, starting in 306 AD with the usurpation of Maxentius and the defeat of Severus and ending with the defeat of Licinius at the hands of Constantine I in 324 AD.

Diocletian, nicknamed "Jovius", was Roman emperor from 284 until his abdication in 305. He was born Diocles to a family of low status in the Roman province of Dalmatia. Diocles rose through the ranks of the military early in his career, eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name Diocletianus. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.

Caesar is a title of imperial character. It derives from the cognomen of Julius Caesar, a Roman dictator. The change from being a familial name to a title adopted by the Roman emperors can be traced to AD 68, following the fall of the Julio–Claudian dynasty.

Flavius Dalmatius Caesar was a Caesar (335–337) of the Roman Empire, and member of the Constantinian dynasty.

Flavius Hannibalianus was a member of the Constantinian dynasty, which ruled over the Roman Empire in the 4th century AD.

Constantius II was Roman emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars, court intrigues, and usurpations. His religious policies inflamed domestic conflicts that would continue after his death.

Flavius Julius Constans, sometimes called Constans I, was Roman emperor from 337 to 350. He held the imperial rank of caesar from 333, and was the youngest son of Constantine the Great.

Constantine II was Roman emperor from 337 to 340. Son of Constantine the Great and co-emperor alongside his brothers, his attempt to exert his perceived rights of primogeniture led to his death in a failed invasion of Italy in 340.

Aquileia is an ancient Roman city in Italy, at the head of the Adriatic at the edge of the lagoons, about 10 kilometres (6 mi) from the sea, on the river Natiso, the course of which has changed somewhat since Roman times. Today, the city is small, but it was large and prominent in classical antiquity as one of the world's largest cities with a population of 100,000 in the 2nd century AD and is one of the main archaeological sites of northern Italy. In late antiquity the city was the first city in the Italian Peninsula to be sacked by Attila the Hun.

The Jewish revolt against Constantius Gallus erupted during the Roman civil war of 350–353, upon destabilization across the Roman Empire. In 351–352 the Jews of Roman Palaestina revolted against the rule of Constantius Gallus, brother-in-law of Emperor Constantius II and Caesar of the eastern part of the Roman Empire. The revolt was crushed by Gallus' general Ursicinus.

Constans II was caesar or heir apparent to his father Emperor Constantine III from 407 to 409 and co-emperor with Constantine and the Western Roman Emperor Honorius from 409 until his death. Constans was a monk prior to his father being acclaimed emperor by the army in Britain in early 407. Constans was summoned to the new imperial court, in Gaul, appointed to the position of Caesar and swiftly married so that a dynasty could be founded. In Hispania, Honorius's relatives rose in 408 and expelled Constantine's administration. An army under the generals Constans and Gerontius was sent to deal with this and Constantine's authority was re-established. Honorius acknowledged Constantine as co-emperor in early 409 and Constantine immediately raised Constans to the position of co-emperor, theoretically equal in rank to Honorius as well as to Constantine. Later in 409 Gerontius rebelled, proclaimed his client Maximus emperor and incited barbarian groups in Gaul to rise up. Constans was sent to quash the revolt, but was defeated and withdrew to Arles. In 410, Constans was sent to Hispania again. Gerontius had strengthened his army with barbarians and defeated Constans; the latter withdrew north and was defeated again and killed at Vienne early in 411. Gerontius then besieged Constantine in Arles.

Jovinus was a Gallo-Roman senator and claimed to be Roman Emperor.

Hispania was the Roman name for the Iberian Peninsula and its provinces. Under the Roman Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Hispania Tarraconensis. Subsequently, the western part of Tarraconensis was split off, first as Hispania Nova, later renamed "Callaecia". From Diocletian's Tetrarchy onwards, the south of the remainder of Tarraconensis was again split off as Carthaginensis, and all of the mainland Hispanic provinces, along with the Balearic Islands and the North African province of Mauretania Tingitana, were later grouped into a civil diocese headed by a vicarius. The name Hispania was also used in the period of Visigothic rule.

Joannes or John was western Roman emperor from 423 to 425.

Flavius Felix, sometimes erroneously called Constantius Felix, was a general of the Western Roman Empire, who reached the prominent rank of patrician before being killed probably by order of Aetius. For his consulate, in 428, he issued some consular diptychs, one of which has been preserved until modern times.

Galla Placidia, daughter of the Roman emperor Theodosius I, was a mother, tutor, and advisor to emperor Valentinian III, and a major force in Roman politics for most of her life. She was queen consort to Ataulf, king of the Visigoths from 414 until his death in 415, briefly empress consort to Constantius III in 421, and managed the government administration as a regent during the early reign of Valentinian III, until her death.

The Battle of Rimini was fought in 432 between the two strong men of the Western Roman Empire, the very recently deposed Magister Utriusque Militiae Flavius Aetius and the newly appointed Magister Utriusque Militiae Bonifatius.

Magister militum was a top-level military command used in the later Roman Empire, dating from the reign of Constantine the Great. The term referred to the senior military officer of the empire. In Greek sources, the term is translated either as strategos or as stratelates.
