Bertrand des Baux

Bertrand des Baux (c. 1238–1305), youngest son of Barral des Baux and Sibylle d'Anduze, was the first Angevin count of Avellino. In 1265 he joined Charles of Anjou's conquest of the Kingdom of Sicily, and in 1268 Charles granted him the county of Avellino; he fought at Tagliacozzo the same year. In 1270–1271 he was Charles's vicar of Rome.

Avellino rebelled against his harsh rule in 1276. In 1287, commanding a fleet against Sicily, he was captured by the Aragonese near Augusta; after ransom he negotiated a two-year truce, and died in Provence in 1305.
