AD 383	Magnus Maximus, British commander of the Roman army, makes himself Emperor and takes most of the army with him when he goes to Rome to claim the throne. He loses and is executed but the soldiers don’t come back to Britain.
AD 398	More tribes invade. Emperor Honorius sent his chief general, Stilicho, with an army to defend Britain.
AD 406	There is a rebellion by soldiers in Britain and a man called Constantine is declared emperor. By now German tribes have invaded Gaul. Saxon pirate ships patrol the coast and Britain is cut off from Rome.
