Marcus Aurelius Valerius Maxentius (c. 283 – 28 October 312) was a Roman emperor from 306 until his death in 312. Despite ruling in Italy and North Africa, and having the recognition of the Senate in Rome, he was not recognized as a legitimate emperor by his fellow emperors.
He was the son of former Emperor Maximian and the son-in-law of Emperor Galerius. The latter part of his reign was preoccupied with civil war, allying with Maximinus against Licinius and Constantine. The latter defeated him at the Battle of the Milvian Bridge in 312, where Maxentius, with his army in flight, purportedly perished by drowning in the Tiber river.
Maxentius was the last emperor permanently to reside in Rome. He attempted to embellish, restore and improve the ancient capital, carrying out important building works, including the Temple of the Divine Romulus (dedicated to his deceased son), the Basilica of Maxentius, which was completed by Constantine, the villa and the circus of Maxentius.
Early life, family, and accession
Maxentius was the son of Emperor Maximian and his Syrian wife Eutropia. As his father became emperor in 285, he was regarded as the crown prince who would eventually follow his father on the throne. He seems not to have served, however, in any important military or administrative position during the reign of Diocletian and his father. The exact date of his marriage to Valeria Maximilla, daughter of Galerius, is unknown. He had two sons, Valerius Romulus and an unknown one.
In 305, Diocletian and Maximian abdicated, and the former Caesares Constantius and Galerius became Augusti. Although two sons of emperors – Constantine and Maxentius – were available, they were passed over for the new tetrarchy, and Valerius Severus and Maximinus Daza were appointed Caesars. Lactantius' Epitome states that Galerius hated Maxentius and used his influence with Diocletian to see that Maxentius was ignored in the succession; perhaps Diocletian also thought Maxentius was not qualified for the military duties of the imperial office. Maxentius retired to an estate some miles from Rome.
When Constantius died in 306, his son Constantine was crowned emperor on July 25 and subsequently accepted by Galerius into the Tetrarchy as Caesar. This set the precedent for Maxentius' accession later in the same year.
When rumours reached the capital that the emperors tried to subject the Roman population to the capitation tax, like every other city of the empire, and wanted to dissolve the remnants of the Praetorian Guard which were still stationed at Rome, riots broke out. A group of officers of the city's garrisons (Zosimus calls them Marcellianus, Marcellus and Lucianus) turned to Maxentius to accept the imperial purple, probably judging that the official recognition which was granted to Constantine would not be withheld from Maxentius, son of an emperor as well. Maxentius accepted the honour, promised donations to the city's troops, and was publicly acclaimed emperor on 28 October 306. The usurpation obviously went largely without bloodshed (Zosimus names only one victim); the prefect of Rome went over to Maxentius and retained his office. Apparently the conspirators also approached Maximian, who had retired to a palace in Lucania, but he declined to resume power for the time being.
Maxentius managed to be recognized as emperor in Central Italy and Southern Italy, the islands of Corsica and Sardinia and Sicily, and the African provinces. Northern Italy remained under the control of the western Augustus Valerius Severus, who resided in Mediolanum (Milan).
Maxentius refrained from using the titles Augustus or Caesar at first and styled himself princeps invictus ("undefeated prince"), in the hope of obtaining recognition of his reign by the senior emperor Galerius. However, the latter refused to do so. Apart from his alleged antipathy towards Maxentius, Galerius probably wanted to deter others from following the examples of Constantine and Maxentius and declaring themselves emperors. Constantine firmly controlled his father's army and territories, and Galerius could pretend that his accession was part of the regular succession in the tetrarchy, but neither was the case with Maxentius: he would be the fifth emperor, and he had only few troops at his command. Galerius reckoned that it would be not too difficult to quell the usurpation, and early in 307, the Augustus Severus marched on Rome with a large army.
The majority of this army consisted of soldiers who had fought under Maxentius' father Maximian for years, and as Severus reached Rome, the majority of his army went over to Maxentius and received a large amount of money. When Maximian himself finally left his retreat and returned to Rome to assume the imperial office once again and support his son, Severus with the rest of his army retreated to Ravenna. Shortly after, he surrendered to Maximian, who promised that his life would be spared.
After the defeat of Severus, Maxentius took possession of northern Italy up to the Alps and the Istrian peninsula to the east, and assumed the title of Augustus, which (in his eyes) had become vacant with the surrender of Severus.
The joint rule of Maxentius and Maximian in Rome was tested further when Galerius marched to Italy in the summer of 307 with an even larger army. While negotiating with the invader, Maxentius could repeat what he did to Severus, by the promise of large sums of money and the authority of Maximian, many soldiers of Galerius defected to him. Galerius was forced to withdraw, plundering Italy on his way. Some time during the invasion, Severus was put to death by Maxentius, probably at Tres Tabernae near Rome (the exact circumstances of his death are not certain). After the failed campaign of Galerius, Maxentius' reign over Italy and Africa was firmly established. Beginning in 307, he tried to arrange friendly contacts with Constantine and in the summer of that year, Maximian travelled to Gaul, where Constantine married his daughter Fausta and was in turn appointed Augustus by the senior emperor. Constantine tried to avoid breaking with Galerius and did not openly support Maxentius during the invasion.
In 308, probably April, Maximian tried to depose his son in an assembly of soldiers in Rome; surprisingly to him, the present troops remained faithful to his son and he had to flee to Constantine. On 20 April, Maxentius proclaimed himself as the new consul of the year, alongside his son Romulus. In the conference of Carnuntum, in the autumn of that same year, Maxentius was once again denied recognition as legitimate emperor, and Licinius was appointed Augustus with the task of regaining the lost domains.
Late in 308, Domitius Alexander was acclaimed as a rival emperor in Carthage, and the African provinces seceded from Maxentian rule. This produced a dangerous situation for Maxentius, as Africa was critical to Rome's food supply. In addition to Africa, the island of Sardinia also defected to the usurper. There is evidence to support that Constantine secretly allied himself with Alexander in opposition to Maxentius. In any event, a small army, led by Maxentius's praetorian prefect Rufius Volusianus, invaded Africa and defeated Alexander around 310. Maxentius executed the usurper and seized the wealth of his supporters, as well as bringing large amounts of grain to Rome.
Maxentius' eldest son Valerius Romulus died in 309, at the age of about fourteen, was deified and buried in a mausoleum in the Villa of Maxentius at the Via Appia. Nearby, Maxentius also constructed the Circus of Maxentius. After the death of Maximian in 309 or 310, relations with Constantine rapidly deteriorated and Maxentius allied with Maximinus to counter an alliance between Constantine and Licinius. He allegedly tried to secure the province of Raetia north of the Alps, thereby dividing the realms of Constantine and Licinius (reported by Zosimus); the plan was not carried out, as Constantine acted first.
In 310, Maxentius lost Istria to Licinius, who could not continue the campaign. By the middle of 310 Galerius had become too ill to involve himself in imperial politics and he died soon after 30 April 311. Galerius' death destabilized what remained of the Tetrarchic system. On hearing the news, Maximinus mobilized against Licinius and seized Asia Minor before meeting Licinius on the Bosphorus to arrange terms for peace. Meanwhile Maxentius strengthened his support among the Christians of Italy by allowing them to elect a new Bishop of Rome, Eusebius.
