 The usurpation of power over Britain and northern Gaul by Carausius just twenty years later reflects a continuing trend by which local loyalties from the landed aristocracy and deteriorating morale in the legions enabled Carausius to seize power in Britain.Similarly with the withdrawal of legions after 408, many Britons desired a localized Roman authority rather than nationalist revolt.The desire for Roman order and institutions was entirely compatible with a degree of national or regional separatism.
