With Guerao Gullielm De Sidot and Corrado Spadafora, the captain and castellan of Lipari, he joined his younger brother Sancho (Sanciolo) in a pro-Angevin revolt in 1357.
In March 1359 he fell out with Anjou and helped his cousin the king put down what remained of the insurrection.
He was rewarded with the lordship of Termini and the county of Novara, which had been his maternal grandfather's, in 1364.
From his nephew Mattiotto, the son of Sancho, he inherited the county of Cammarata in 1369.
From 1365 to 1368 he acted as Grand Chancellor of Sicily, replacing Enrico Rosso.
