128. Carausius

Marcus Aurelius Mausaeus Carausius (d. 293) was a Roman usurper in Britain and northern Gaul (286–293, Carausian Revolt).

Carausius was a man of humble origin, a Menapian from Belgic Gaul who distinguished himself during Maximian's campaign against the Bagaudae rebels in Gaul in 286. As a result, he was appointed to command the Classis Britannica, a fleet based in the English Channel, with the responsibility of eliminating Frankish and Saxon pirates who had been raiding the coast. However, he was suspected of keeping captured treasure for himself, and even of allowing the pirates to carry out raids and enrich themselves before taking action against them, and Maximian ordered his execution. In late 286 or early 287 Carausius learned of this sentence and responded by declaring himself Emperor of Britain and northern Gaul.

He could count on the alliegance of the three legions based in Britain, as well as one in northern Gaul. How he was able to win support from the army when his command had been sea-based is uncertain. The emperor briefly assumed the title Britannicus Maximus in 285, and the British towns of Wroxeter and Caistor by Norwich towns show signs of destruction around this time, so it is possible Carausius won the army's support during military action in Britain shortly before his rebellion. Alternatively, if the accusations of larceny are true, he could perhaps afford to buy their loyalty. He also appears to have appealed to native British dissatisfaction with Roman rule: he issued coins with legends such as Restitutor Britanniae (Restorer of Britain) and Genius Britanniae (Spirit of Britain).

Maximian, busy with wars on the Rhine, was unable to challenge him immediately, but in the Autumn of 288 he began massing troops and ships for an invasion. In 289 an invasion of Britain intended to dislodge him failed badly due to storms, although a naval defeat is also possible. An uneasy peace continued until 293, during which Rome prepared for a second effort to retake the province, while Carausius began to entertain visions of legitimacy and official recognition. He minted his own coins and brought their value in to line with Roman issues as well as acknowledging and honouring Maximian and then Diocletian. Coinage is the main source of information about the rogue emperor; his issues were initially crude but soon became more elaborate and were issued from mints in Londinium, Rotomagnus and a third site, possibly Colonia Claudia Victricensis. A milestone from Carlisle with his name on it suggests that the whole of Roman Britain was in Carausius' grasp.

It has been speculated (namely, by the historian Sheppard Frere) that the rebellion of Carausius endangered Diocletian's vision of a strong, centralized government based on his tetrarchy. In any case, by early 293 Constantius Chlorus had gained control of northern Gaul, including the rebel's stronghold and port of Bononia, on which Carausius was heavily dependent. Constantius built a mole across the harbour mouth to ensure it did not receive maritime aid.

Constantius also regained the allegiance of the rebellious Gallic legion and defeated the Franks of the Rhine mouth who seem to have been working in league with Carausius. Weakened by these setbacks, Carausius was assassinated, possibly at York, by his treasurer, Allectus.
