The Basques ( BAHSKS or BASKS; Basque: euskaldunak [eus̺kaldunak]; Spanish: vascos [ˈbaskos]; French: basques [bask]) are a Southwestern European ethnic group, characterised by the Basque language, a common culture and shared genetic ancestry to the ancient Vascones and Aquitanians. Basques are indigenous to, and primarily inhabit, an area traditionally known as the Basque Country (Basque: Euskal Herria)—a region that is located around the western end of the Pyrenees on the coast of the Bay of Biscay and straddles parts of north-central Spain and south-western France.
I give the link to this online article, and at least initially, I make no comment. Much varied information.
