Rome fought Carthage in the Second Punic War (218–201 BC), and the Gauls typically sided with Carthage. After the war, Rome took Bononia (196 BC), Placentia (194 BC) and Mutina (193 BC). According to Strabo, many of the surviving Boii retreated north across the Alps to the land subsequently known as Boihaemum, but in all probability the region was already inhabited by Boii prior to their subjugation in Italy.
