Sub-Roman Britain, also called post-Roman Britain or Dark Age Britain, is the period of late antiquity in Great Britain between the end of Roman rule and the founding of Anglo-Saxon kingdoms. The term was originally used to describe archaeological remains found in 5th- and 6th-century AD sites that hinted at the decay of locally made wares from a previous higher standard under the Roman Empire. It is now used to describe the period that began with the recall of Roman troops from Britannia to Gaul by Constantine III in 407 and ended with the Battle of Deorham in 577. This period has attracted a great deal of academic and popular debate, in part because of the lack of written records from the time.
