The Punic Wars form a kind of episode in the history of Europe, just as the presence of a Punic people in the Western Mediterranean is of itself an anomaly and in some sort an episode. The existence of the Carthaginian power hindered what we might have looked on as the natural course of history for the three great European peninsulas. When Rome had become the undisputed head of Italy, the next growth of her power might have been looked for in the direction of the Gaul and of the Greek. The headship of Italy had been won by driving back a Greek invasion, an invasion from a Greek land within sight of Italy, and that headship might be looked on as imperfect till it was further spread over Sicily at one end and Cisalpine Gaul at the other. Sicily was at once fought for, and in the end won; but it had to be won from the intruding Carthaginian. When the first Punic War was over, the eyes of Rome were again drawn beyond the Po and beyond the Hadriatic. The conquest of Cisalpine Gaul was begun; the Illyrian wars led to the first establishment of Rome as an influence, as a power, in the Eastern peninsula. Protector, mistress in all but name, of Korkyra, Epidamnos, and Apollônia, Rome has become an element in the affairs of Greece herself as well as in those of Greek colonies in Italy, Sicily, Spain, and Gaul. She has won the jealousy of Macedonia, the good will of the free states of Greece. That is, she has taken the first steps towards bringing Greek friends and Greek enemies alike, first under her influence and then under her dominion.
