Roman Civil war of 407–415:Constantine III, a general (magister militum), declares himself Roman emperor. To extend his dominion over Gaul and Spain, he takes practically all the Roman garrisons from Britain and crosses the English Channel. Constantine occupies Arles and establishes tenuous authority over Gaul, sharing control with marauding "barbarians". This is generally seen as the beginning of Rome's withdrawal from Britain.
