386 BC during their advance against the Volsci in Valle del Sacco, then transformed into municipium under the Romans garrison. The taking of the urban center of Frosinone, which then as today is located in the center of the Sacco Valley, determined an important strategic victory for the Romans, who with this city could easily control all transits and commercial traffic between the north and the south of the peninsula. In 306 BC, the city took part in the Hernic League against Rome; defeated and sacked, it lost much of its territories to the nearby Ferentino. Later, during the Second Punic War, it was devastated by Hannibal's armies, to which it refused to surrender.
