Hugues IV des Baux
Hugues IV des Baux (died 1351) was a Provençal lord who became count of Avellino and admiral of Sicily. He was the son of Raymond III.
In Naples, Queen Joanna's husband Louis of Taranto had held the real power since 1348. In July 1350, with papal blessing, Hugues sailed from Marseille with six galleys to free the queen from him. The expedition succeeded, and he used the moment to marry his heir Robert to Maria, widow of Charles of Durazzo.
Then one of his captains betrayed him to Louis, who had him executed in 1351 and took back full power. Hugues's sons Robert, now count of Avellino, and Raymond were imprisoned.
