ローマ海軍
Allectus was treasurer to Carausius, a Menapian officer in the Roman navy who had seized power in Britain and northern Gaul in 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 Frankish allies of Carausius in Batavia. Allectus assassinated Carausius and assumed command himself.
