The term is also used geographically in 'Anglo-Celtic Isles', to describe a period of British military history in 'Anglo-Celtic Warfare' and as a notional racial category.
"Anglo", in this instance, is an abbreviation for Anglo-Saxon, a collective term for ancient Germanic peoples who settled in Britain (especially England) in the middle of the first millennium. As the Normans who arrived from France and settled mainly in England after 1066 AD are commonly known as 'Anglo-Norman', the term can also be inclusive of this cultural group.
"Celtic", in this instance, refers to the Celtic peoples predominantly inhabiting Ireland, Scotland and Wales. The term does not include the Celtic peoples of mainland or continental Europe, such as the Bretons.
There is a newspaper sold in the Irish counties of Cavan, Fermanagh and Monaghan named ‘The Anglo-Celt’.
Some archaeologists and historians claim recent research suggests that the British Celts were not entirely wiped out or driven away from the areas conquered by the Anglo-Saxons from the fifth century onwards. Further, they claim that in most places in England, the indigenous population and the newcomers enjoyed forms of relatively peaceful coexistence. They claim that this, and the subsequent process of language shift on the part of the Celtic population, left more traces in the English language than has hitherto been assumed.
To a lesser degree the term is also used in Canada, England, Ireland, New Zealand, and the United States. It is used by traditionalists in the Southern United States, such as the League of the South, whose mission statement is "to protect the historic Anglo-Celtic core culture of the South because the Scots, Irish, Welsh, and English have given Dixie its unique institutions and civilization
