Charles of Artois, Count of Pézenas
Charles of Artois (1328–1385), count of Pézenas, was the youngest son of Robert III of Artois and Joan of Valois. In 1334 his uncle Philip VI shut him and his brothers in Château-Gaillard; John II freed him on his accession in 1350 and made him a councillor. In 1356 he received Longueville, confiscated from Philip of Navarre, and helped take Évreux and Breteuil from Charles the Bad.
Captured at Poitiers, he spent four years in London. Longueville was taken back in 1360, and in 1362 Pézenas was raised to a county as compensation. Hoping to win Artois, he joined the Prince of Wales's companies in 1367; his exactions led Charles V to confiscate his property.
Reconciled in 1375, he stirred up trouble again, and the Duke of Anjou arrested him at Agde. He died in 1385.
