United Kingdom

Abstract

Cut off from continental Europe by the Channel, Britain remained for long more or less inaccessible to migrants in large numbers and thus largely immune to external influences. Thus the British Isles have only experienced five major invasions by foreigners, the last being in 1066: the Celts, one of whose tribes was the Britons, in the first millennium BC, the Romans, the Anglo-Saxons, the Vikings and the Normans.
