407 CE
End of Roman rule in Britain: After 360 years of occupation, the local regional British-Roman leaders raise their own levies for defence against Saxon sea rovers. They cultivate oysters, having learned the technique from the Romans. Liu Bobo (Xia Wuliedi) founds the state of Xia, and claims the title "Heavenly Prince" (Tian Wang). 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.
