“Angles: A Germanic people first heard of on the Baltic coasts of Jutland. On the evidence of their pottery found at a number of late Roman settlements in England, they were probably present as Foederati in the later c4 AD. In c5 they took part in the Anglo-Saxon migrations across the North Sea to settle the eastern parts of England after the breakdown of Roman rule. The archaeological evidence is treated under Anglo-Saxons since by this period the distinction between the two peoples had all but disappeared. Their names survives in East Anglia and England.”
