Carausius

Marcus Aurelius Mausaeus Carausius (died 293) 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.

Allectus (died 296) was a Roman-Britannic usurper in Britain and northern Gaul from 293 to 296.

Bagaudae (also spelled plu. bacaudae or bacauda singular) were groups of peasant insurgents in the western parts of the later Roman Empire, who arose during the Crisis of the Third Century and persisted until the very end of the Western Empire, particularly in the less-Romanised areas of Gallia and Hispania. They were affected by the depredations of the late Roman state, wealthy landowners, and clerics.
