from Encylopedia Britannica:
Angle, member of a Germanic people, which, together with the Jutes, Saxons, and probably the Frisians, invaded the island of Britain in the 5th century ce. The Angles gave their name to England, as well as to the word Englisc, used even by Saxon writers to denote their vernacular tongue. The Angles are first mentioned by Tacitus (1st century ce) as worshippers of the deity Nerthus. According to the Venerable Bede in the Ecclesiastical History of the English People, their Continental homeland was centred in Angulus, traditionally identified as the Angeln district in Schleswig between the Schlei inlet and the Flensburger Förde, which they appear to have abandoned at the time of their invasion of Britain. They settled in large numbers during the 5th and 6th centuries in what became the kingdoms of Mercia, Northumbria, and East and Middle Anglia.
And before them: Celt, also spelled Kelt, Latin Celta, plural Celtae, a member of an early Indo-European people who from the 2nd millennium bc to the 1st century bc spread over much of Europe. Their tribes and groups eventually ranged from the British Isles and northern Spain to as far east as Transylvania, the Black Sea coasts, and Galatia in Anatolia and were in part absorbed into the Roman Empire as Britons, Gauls, Boii, Galatians, and Celtiberians. Linguistically they survive in the modern Celtic speakers of Ireland, Highland Scotland, the Isle of Man, Wales, and Brittany.

So yeah, lets get rid of them foreigners... but which ones? At least Italians are noted for their cusine... LOL.
