X on an expedition into Flanders in 1315, and died on his return to France in the same year. His eldest son, Gaston II, made peace with the house of Armagnac and took part in various wars both in France and Spain, dying at Seville in 1343, when he was succeeded by his young son, Gaston III. Gaston III (1331–1391), called Phoebus, the Latin version of Apollo, on account of his beauty, was the most famous member of the House of Foix-Béarn. Like his father he assisted France in her struggle against England, being entrusted with the defence of the frontiers of Gascony. When the French king, John II, favored the count of Armagnac, Gaston left his service and went to fight against the pagans of Prussia. Returning to France around 1357, he delivered some noble ladies from the attacks of the adherents of the Jacquerie at Meaux, and was soon at war with the count of Armagnac. During this struggle he also attacked the count of Poitiers, the royal representative in Languedoc, but owing to the intervention of Pope Innocent VI he made peace with the count in 1360. Gaston, however, continued to fight against the count of Armagnac, who, in 1362, was defeated and compelled to pay a ransom. This war lasted until 1377. Early in 1380, the count was appointed governor of Languedoc, but when Charles VI succeeded Charles V as king later in the same year, this appointment was cancelled. Refusing, however, to heed the royal command, and supported by the communes of Languedoc, Gaston fought for about two years against John, duke of Berry, who had been chosen as his successor. When he was bested in the combat, he abandoned the struggle and retired to his estates, remaining neutral and independent. He then resided in Orthez, the capital of Béarn. In 1348 Gaston married Agnes, daughter of Philip, Count of Evreux (d. 1343), by his wife Jeanne II, queen of Navarre. By Agnes, whom he divorced in 1373, he had an only son, Gaston, who is said to have been incited by his uncle, Charles II of Navarre, to poison his father, and who met his death in 1381. It is probable that he was killed by his father; this is the account presented by Froissart. Gaston was very fond of hunting, but was not without a taste for art and literature.
