The Celtic nations or Celtic countries[1] are a cultural area and collection of geographical regions in Northwestern Europe where the Celtic languages and cultural traits have survived.[2] The term nation is used in its original sense to mean a people who share a common identity and culture and are identified with a traditional territory.[according to whom?]
The six regions widely considered Celtic countries in modern times are Brittany (Breizh), Cornwall (Kernow), Ireland (Éire), the Isle of Man (Mannin, or Ellan Vannin), Scotland (Alba), and Wales (Cymru).[1][3] In each of these six regions a Celtic language is spoken to some extent: Brittonic or Brythonic languages are spoken in Brittany (Breton), Cornwall (Cornish), and Wales (Welsh), whilst Goidelic or Gaelic languages are spoken in Scotland (Scottish Gaelic), Ireland (Irish), and the Isle of Man (Manx).[4]
Before the expansion of Ancient Rome and the spread of Germanic and Slavic tribes, much of Europe was dominated by Celtic-speaking cultures, leaving behind a legacy of Celtic cultural traits.[5] Certain regions with evidence of Celtic influence in northwestern Iberia, such as Galicia, Asturias, northern Portugal, León, and Cantabria (historically known as Gallaecia and Astures), are not typically considered Celtic nations.[6] Unlike the Insular Celtic languages, there's no record of Celtic languages surviving into the modern era in these regions.[6][7][8] Similar evidence of a pattern of Celtic influence without the long-term survival of Celtic languages is also found in various regions across Europe, including parts of Italy, Austria, and the Czech Republic.
The concept of the Celtic nations is widely promoted by pan-Celtic movements, including political and cultural organizations like the Celtic League or International Celtic Congress.
