The Romans had invaded England and ruled over England for 400 years but in 410, the Romans left England because their homes in Italy were being attacked by fierce tribes and every soldier was needed back in Rome.
Who defeated the Romans in Britain?
The Romans met a large army of Britons, under the Catuvellauni kings Caratacus and his brother Togodumnus, on the River Medway, Kent. The Britons were defeated in a two-day battle, then again shortly afterwards on the Thames.
