This and the following centuries witnessed incessant wars against the Ravennatese, the Faentines and the Bolognese, as well as the internecine struggles of the Castrimolesi (from Castro Imolese, "castle of Imola") and the Sancassianesi (from San Cassiano).
U ovom i sljedećim stoljećima uslijedili su neprekidni ratovi protiv Ravenaca, Faentinaca i Bolonjaca, kao i međusobni sukobi Castrimolesa (od Castro Imolese, 'imolski dvorac') i Sancassianesa (od San Cassiano).
