Roger-Bernard of Périgord

Roger-Bernard (c. 1299–1361), a younger son of Count Hélie IX and Brunissende of Foix, became Count of Périgord in 1334 when his childless brother Archambaud IV died. Until 1340 he contested the lordship of Bergerac with Mathe d’Albret, the wife of his late brother.

With the Hundred Years’ War, Périgord came under repeated attack: the Earl of Derby raided it in 1345, and in 1356 the Black Prince entered Périgueux unopposed, on the ride that ended at Poitiers with King John II’s capture. The Treaty of Brétigny in 1360 put the county under English sovereignty. Roger-Bernard died the next year, and his son Archambaud V succeeded him.
