Robert of Baux

Robert des Baux was the eldest son of Hugues IV des Baux, count of Avellino and lord of Les Baux. In 1350 his father sailed from Marseille with six galleys to free Queen Joanna I from Louis of Taranto, and used the intervention to marry Robert to Maria of Calabria, the throne's designated heiress.

Handed to Louis, Hugues was executed in 1351 and Robert imprisoned, though he became count of Avellino. His forced marriage proved fatal: Maria had him killed in 1354.
