The disaster of Caudium shook the fate of many of the Roman allies, and the fortune of war was for some years in favor of the Samnites. But in B.C. 314 the tide of success again turned, and the decisive victory of the Consuls in that year opened the way into the heart of Samnium. From this time the Romans were uniformly successful; and it seemed probable that the war was drawing to a close, when the Etruscans created a powerful diversion by declaring war against Rome in B.C. 311. But the energy and ability of Q. Fabius Maximus averted this new danger. He boldly carried the war into the very heart of Etruria, and gained a decisive victory over the forces of the League. The Samnites also were repeatedly defeated; and after the capture of Bovianum, the chief city of the Pentri, they were compelled to sue for peace. It was granted them in B.C. 304, on condition of their acknowledging the supremacy of Rome. At the conclusion of the Second Samnite War the AEquians and Hernicans were reduced to subjection after a brief struggle. A part of the AEquian territory was incorporated in that of Rome by the addition of two new tribes, and two colonies were planted in the other portion. The Marsi, Marrucini, Peligni, and other nations of Central Italy, entered into a league with the Romans on equal terms. Thus, in B.C. 300, the power of Rome seemed firmly established in Central Italy. But this very power awakened the jealousy of the surrounding nations, and the Samnites exerted themselves to form a new and formidable coalition. The Etruscans and Umbrians agreed to make war against Rome, and called in the assistance of the Senonian Gauls.
