Allectus

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

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.

Constantius launched an invasion to depose him in September 296. His forces sailed in several divisions. Constantius led one division from Bononia, but seems to have been delayed by bad weather. Another division, under the praetorian prefect Asclepiodotus, took advantage of fog to avoid Allectus's ships stationed at the Isle of Wight, and landed near Southampton Water, where they burnt their ships. Allectus's forces were forced to retreat from the coast, but were cut off by another of Constantius's divisions and defeated. Allectus himself was killed in the battle, having removed all insignia in the hope that his body would not be identified
