 County of Fézensac

The County of Fézensac was an 8th-century creation on the north-eastern fringes of the Duchy of Gascony following Charlemagne's policy of feudalisation and Frankish colonisation.The move was aimed at offsetting and undermining the authority of the duke of Gascony Lupo II after the setback suffered by the Franks at the Battle of Roncevaux in 778 and failure to restrain the Basques.
