Roger-Bernard III, Count of Foix

His conflict with Philip III was rooted in the longstanding desire of the French monarchy to establish its authority in Languedoc, where, since the 10th century, it had been practically a dead letter.

In 1272, Roger-Bernard allied with Gerald VI, Count of Armagnac to attack the lord of Sompuy,[2] who, however, applied for protection to the king.

Before the end of that year, the count of Foix was released and did homage to the king of France,[4] receiving back a portion of his confiscated lands.

In gladful compensation for this, Philip III restored all the count's remaining territories south of the Pas de La Barre.

Though slightly modified a little later (the same year), the paréage remains the governing system of Andorra to this day, though the office of Count of Foix has devolved to the Presidency of France since that time.

The count of Foix formed a coalition of other dissatisfied Catalan nobles, including Arnold Roger I of Pallars Sobirà and Ermengol X of Urgell, and revolted against Peter.

In 1290, Roger-Bernard tried to stop the seneschals of Toulouse and Carcassonne from interfering in his internal affairs, such as the administration of justice and the collection of taxes.

Philip IV, now King of France, refused to call off his functionaries and diminish his own authority in the south and was thus forced to confiscate two of the count's castles as punishment for his disobedience and lack of cooperation with the crown.

In 1293, after three years of peace, Gerard V finally contested the usurpation of Béarn and began a long war with Roger-Bernard over the rights of their wives.

When the aforementioned Guillemette donated all her Catalan lands to James II of Aragon in April 1300, Roger-Bernard opposed her and traveled at the head of troops through the pass of the Col de Puymorens in the Pyrenees.
