Magnus Magnentius (c. 303 – 11 August 353) was a usurper of the Roman Empire from 350 to 353.

Early life and career[]

Born in Samarobriva (Amiens), Gaul, Magnentius was the commander of the Herculians and Jovians, the Imperial guard units.^[1] When the army grew dissatisfied with the behavior of Emperor Constans, it elevated Magnentius at Autun on 18 January 350.^[2] Constans was hunting near the Pyrenees, away from his forces, when Magnentius' forces cornered and killed him at Helene (near Perpignan).^[2]

Magnentius quickly attracted the loyalty of the provinces in Britannia, Gaul, and Hispania, in part because he proved to be far more tolerant toward both Christians and Pagans. His control of Italia and Africa was secured through the election of his men to the most important offices. However, the short-lived revolt of Nepotianus, a member of the Constantinian dynasty, showed Magnentius that his status as emperor needed to be consolidated.

Magnentius tried to strengthen his grasp on the territories previously controlled by Constans, moving towards the Danube. Vetranio, commander of the Pannonian army, had been elected Augustus by his troops in Mursa on 1 March. This revolt had a loyalist mark, since Vetranio was supported by Constantina, and Constantius II himself recognized Vetranio, sending him the imperial diadem.

Demise[]

The remaining emperor of the family of Constantine I, Constantius II, broke off his war with Persia, and marched west from Syria. Despite Magnentius' efforts to win Vetranio over to his cause, the elderly Vetranio reached Constantius with his army, resigned the crown, and went into retirement in Bithynia.

After electing Magnus Decentius (probably his brother) as Caesar and gathering as many troops as possible, Magnentius advanced his armies to meet those of Constantius in the Battle of Mursa Major in 351; Magnentius led his troops into battle, while Constantius spent the day of battle praying in a nearby church. Despite Magnentius' heroism, his troops were defeated and forced to retreat back to Gaul.

As a result of Magnentius' defeat, Italy ejected his garrisons and rejoined the loyalist cause. Magnentius made a final stand in 353 at the Battle of Mons Seleucus, after which he fled to a place called Lugduna and there committed suicide by falling on his sword.^[3]

Following the suppression of Magnentius' rebellion, Constantius began to root out his followers. The most notorious agent he employed in this search was the primicerius notariorum Paulus Catena ("Paul the Chain").

Some sources state that Magnentius' father was a Briton and his mother a Frank.^[2] His wife, Justina, later married Valentinian I.
