Seven years after their defeat, with Roman dominance of the area looking assured, the Samnites rose again and defeated the Romans at the Battle of Camerinum in 298 BC, to open the Third Samnite War. With this success in hand they managed to bring together a coalition of several previous enemies of Rome, all of whom were probably keen to prevent any one faction dominating the entire region. The army that faced the Romans at the Battle of Sentinum in 295 BC included Samnites, Gauls, Etruscans and Umbrians. When the Roman army won a convincing victory over these combined forces it must have become clear that little could prevent Roman dominance of Italy and in the Battle of Populonia (282 BC) Rome destroyed the last vestiges of Etruscan power in the region.
