Bernard IV of Armagnac
Bernard IV (1136–1193) succeeded his father Géraud III as Count of Armagnac and Fézensac in 1160, and his rule was marked by conflict with Géraud de la Barthe, archbishop of Auch.
He designated his nephew Bernard de Lomagne as heir in case he had no children and in 1184 gave him the viscounty of Fézensaguet. His son Géraud IV succeeded when Bernard died in 1193.
