Allectus

Allectus (d. 296) was a Roman emperor in Britain (293 - 296).

Allectus was the treasurer of Carausius. When Carausius lost control of northern Gaul and its crucial port of Boulogne, Allectus assassinated him and took control. However, Allectus proved unable to prevent the invasion of Constantius I, who launched a two-pronged attack on Britain in 296. Although at least part of the first invasion force under Constantius seems to have been turned back by storms, the second force under the praetorian prefect Asclepiodotus successfully landed and marched toward London. Allectus confronted him at Farnham (in Surrey), but was defeated and killed in battle.
