Allectus was treasurer to Carausius, a Menapian officer in the Roman navy who had seized power in Britain and northern Gaul in AD 286. In 293 Carausius was isolated when the western Caesar, Constantius Chlorus, retook some of his Gallic territories, particularly the crucial port of Bononia (modern Boulogne), and defeated his Frankish allies in Batavia. Allectus assassinated Carausius and assumed command himself. His reign has left little record, although his coin issues display a similar distribution to those of Carausius. They are found in north western Gaul, indicating that the recapture of Bononia did not spell the end of the rebel empire on that side of the English Channel.
