As a result of this victory, many parts of Italy joined Hannibal's cause.Chaplin, Jane Dunbar, Livy's Exemplary History, p. 66 As Polybius notes, "How much more serious was the defeat of Cannae, than those that preceded it can be seen by the behaviour of Rome's allies; before that fateful day, their loyalty remained unshaken, now it began to waver for the simple reason that they despaired of Roman Power."Polybius, The Histories of Polybius, 2 Vols., trans. Evelyn S. Shuckburgh (London: Macmillan, 1889), I. 264–275. During that same year, the Greek cities in Sicily were induced to revolt against Roman political control, while Macedonian King Philip V pledged his support to Hannibal— initiating the First Macedonian War against Rome.
