Read Celtic League (Wikipedia)

The Celtic League is a pan-Celtic organisation, founded in 1961, that aims to promote modern Celtic identity and culture in Ireland, Scotland, Wales, Brittany, Cornwall and the Isle of Man – referred to as the Celtic nations; it places particular emphasis on promoting the Celtic languages of those nations. It also advocates further self-governance in the Celtic nations and ultimately for each nation to be an independent state in its own right. The Celtic League is an accredited NGO with roster consultative status to ECOSOC (The United Nations Economic and Social Council).
