Guelphs and Ghibellines
During the War of the Guelphs and Ghibellines which tore apart Italy from the 12th to the 14th century, the Trinci were initially Guelphs, but switched to the other party from 1240. Corrado (I) and Trincia I Trinci held the title of "podestà" or vicar of Foligno in the late 13th century.
