The Basques are an indigenous ethno-linguistic group primarily inhabiting the Basque Country, a region that spans northeastern Spain and southwestern France. While geographically located in the Iberian Peninsula, Basques are often distinguished from other Iberian populations due to their unique language, culture, and genetic profile. Linguistically, Basque is a language isolate with no known relation to ancient Iberian or Indo-European languages, and is believed to be a descendant of the pre-Indo-European tongues once spoken across Western Europe. Genetically and culturally, Basques are more closely linked to the ancient Aquitani people of what is now southwestern France. Although the northern Aquitani have largely assimilated into French identity, their southern counterparts persisted culturally and linguistically as the Basques. As such, the Basques are considered a distinct non-Indo-European population indigenous to Western Europe, with deep historical roots predating modern national borders.
