Carausius

Marcus Aurelius Mausaeus Carausius (born c. 3rd century AD - died c. 293 AD) was a military commander of the Roman Empire in the 3rd century. He was a Menapian from Belgic Gaul, who usurped power in 286, during the Carausian Revolt, declaring himself emperor in Britain and northern Gaul (Imperium Britanniarum). He did this only 13 years after the Gallic Empire was ended in 273. He held power for seven years, fashioning the name "Emperor of the North" for himself, before being assassinated by his finance minister Allectus.

Early life and assumption of Imperial title

Carausius was of humble origin, a Menapian who distinguished himself during Maximian's campaign against the Bagaudae rebels in northern Gaul in 286. This success, and his former occupation as a pilot, led to his appointment 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 coasts of Armorica and Belgica. He was suspected of allowing pirates to carry out raids and collect loot before attacking them, then keeping captured treasure for himself, and Maximian ordered his execution. In late 286 or early 287 Carausius learned of this sentence and responded by declaring himself Emperor in Britain and northern Gaul. His forces comprised not only his fleet, augmented by new ships he had built and the three legions stationed in Britain, but also a legion he had seized in Gaul, a number of foreign auxiliary units, a levy of Gaulish merchant ships, and barbarian mercenaries attracted by the prospect of booty.

British historian and archaeologist Sheppard Frere wonders how Carausius was able to win support from the army when his command had been sea-based, and speculates that he had perhaps been involved in an unrecorded victory in Britain, connected with Diocletian's assumption of the title Britannicus Maximus in 285, and signs of destruction in Romano-British towns at this time.
