In 859 Cassano and Cosenza were the headquarters of the Gastaldates of the Lombards of the Duchy of Benevento. In their turn the Lombards were attacked again and again, as were the Greeks in south Italy, by the Saracens (Arabs and Moors). The Greeks were able to drive the Saracens away, and reorganized Calabria as part of the Greek Empire and the Greek Church of Constantinople. Cassano was established around this time as a suffragan diocese of the Greek Metropolitan of Reggio Calabria.
