question: Who was responsible for getting rid of the Romans in Britain?
short_answers: Romano-Britains
context: In 383, the usurper Magnus Maximus withdrew troops from northern and western Britain, probably leaving local warlords in charge. Around 410, the Romano-British expelled the magistrates of the usurper Constantine III, ostensibly in response to his failures to use the Roman garrison he had stripped from Britain to protect the island. Roman Emperor Honorius replied to a request for assistance with the "Rescript of Honorius", telling the Roman cities to see to their own defence, a tacit acceptance of temporary British self-government. Honorius was fighting a large-scale war in Italy against the Visigoths under their leader Alaric, with Rome itself under siege. No forces could be spared to protect distant Britain. Though it is likely that Honorius expected to regain control over the provinces soon, by the mid-6th century Procopius recognised that Roman control of Britannia was entirely lost.
question: Who withdrew Roman troops from Britain?
short_answers: Magnus Maximus

Answer: The end of Roman rule in Britain was the transition from Roman Britain to post-Roman Britain. In 383, the usurper Magnus Maximus withdrew troops from northern and western Britain, probably leaving local warlords in charge. Around 410, the Romano-Britains expelled the magistrates of the usurper Constantine III, ostensibly in response to his failures to use the Roman garrison he had stripped from Britain to protect the island. By the early 5th century, the Roman Empire could no longer defend itself against either internal rebellion or the external threat posed by Germanic tribes expanding in Western Europe. This situation and its consequences governed the eventual permanent detachment of Britain from the rest of the Empire.
