Francesco I Sforza
Initially a fierce enemy of the Pope, Trinci was known for plundering monasteries. Attacked by Francesco I Sforza, however, he obtained the title of vicar of Foligno and Nocera Umbra from Pope Martin V. After this appointment, Trinci was sent to recapture Perugia, held at the time by Oddo Fortebracci. In 1428, however, he again rebelled against the Church.
