Before the borders of modern Europe hardened into lines of power stretching across the Pyrenees, the Basque people lived with a quieter kind of authority—rooted in land, language, and community. Since the Middle Ages, they governed themselves through local councils that gathered beneath the great oak of Guernica. That tree was more than a landmark; it was a living symbol of continuity. Its branches offered shelter, its trunk a place of assembly, and its roots a reminder that identity, like nature, is sustained through interdependence and preservation.
