The Carausian Revolt (286 – 296 CE) is an episode in Roman history during which a Roman naval commander, Carausius, declares himself emperor over Britain and northern Gaul.
His Gallic territories are retaken by the western Caesar, Constantius Chlorus, in 293, after which Carausius is assassinated by his subordinate Allectus.
Britain is regained by Constantius and his subordinate Asclepiodotus in 296.
