In the year 660, Felix of Aquitaine, a patrician from Toulouse of Gallo-Roman stock, received the ducal title of both Vasconia and Aquitaine (located between the Garonne and Loire rivers), effectively ruling independently over Vasconia and at least part of Aquitaine. Under Felix and his successors, Frankish overlordship over these lands became merely nominal, and Vasconia became a prominent regional power. The "Ravena Cosmography" cites "Wasconia" as extending up to the Loire, although the real concept behind the name is contested; it further divides the territory into Guasconia (north of Garonne) and Spanoguasconia (south of Garonne).
