Bernard V d'Armagnac

Bernard V (c. 1212–1245) was Count of Armagnac and Fézensac from 1242, when he succeeded his brother Pierre-Géraud. In 1242 he joined Henry III of England's coalition against Alphonse of Poitiers, but the coalition was defeated.

He died in 1245 without children by his wife Agnes. His sister Mascarose, wife of Arnaud Odon of Lomagne, inherited the county, at once claimed by their cousin Géraud of Fézensaguet.
