Barral came to oppose the
Albigensian Crusade, and invaded the
Comtat Venaissin in 1234 in support of
Raymond VII of Toulouse. In 1239, Barral entered negotiations to have his daughter Cecile marry
Guigues VII, Dauphin of Viennois, another supporter of Toulouse. Under pressure from
Philip of Savoy, Barral reneged on the engagement, saying he had only agreed to it in fear of his life. In 1244, Barral helped arbitrate the latest conflict between Savoy and Provence on one side and the dauphin and
Aymar III of Valentinois on the other. In December of that year, Cecile married the Count of Savoy, firmly pulling Baux into the Savoy alliances. In 1246, Barral joined his son-in-law and family in bringing an army to the rescue of
Beatrice of Savoy and her daughter
Beatrice of Provence, who had recently inherited the county of Provence. They had been besieged by others seeking to marry her, but the family was able to safely escort her to her wedding. The countess's new husband did not respect her father's will toward the rest of the family, so Barral joined the Provençal rebellion against
Charles of Anjou in 1247, supporting his son-in-law's family in their rights. Forced to surrender to Charles in June 1251, he became a supporter of Charles by October, and helped suppress the rebellion in 1262. In 1255, Barral was again called on to mediate the disputes between Philip of Savoy and the Valentinois-Viennois alliance. For his support of Charles, he was made Grand Justiciar of
Sicily, and died in 1268. He was succeeded as Lord of Baux by his son
Bertran. ==Marriage and children==
