Basque is the last surviving Paleo-European language spoken indigenously in Europe, predating the Indo-European languages of the Bronze Age invasion of Europe from the Black Sea by pastoralists whose descendant languages dominate the continent today. Basque is spoken by the Basques and other residents of the Basque Country, a region that straddles the westernmost Pyrenees in adjacent parts of northern Spain and southwestern France. Linguistically, Basque is classified as a language isolate, as a relationship to any of the other known extinct pre-Indo-European languages of Europe has not been established, nor is it related to the later arriving Indo-European languages. The Basques are indigenous to, and primarily inhabit, the Basque Country. The Basque language is spoken by 28.4% of Basques in all territories. Of these, 93.2% are in the Spanish area of the Basque Country and the remaining 6.8% are in the French portion.
