The extension of Roman power began in the fifth century B.C. Until that time they had waged war, and generally unsuccessful war, with the Etruscans. There was an Etruscan fort, Veii, only a few miles from Rome which the Romans had never been able to capture. In 474 B.C., however, a great misfortune came to the Etruscans. Their fleet was destroyed by the Greeks of Syracuse in Sicily. At the same time a wave of Nordic invaders came down upon them from the north, the Gauls. Caught between Roman and Gaul, the Etruscans fell—and disappear from history. Veii was captured by the Romans, The Gauls came through to Rome and sacked the city (390 B.C.A.D.) but could not capture the Capitol. An attempted night surprise was betrayed by the cackling of some geese, and finally the invaders were bought off and retired to the north of Italy again. The Gaulish raid seems to have invigorated rather than weakened Rome. The Romans conquered and assimilated the Etruscans, and extended their power over all central Italy from the Arno to Naples. To this they had reached within a few years of 300 B.C. Their conquests in Italy were going on simultaneously with the growth of Philip’s power in Macedonia and Greece, and the tremendous raid of Alexander to Egypt and the Indus. The Romans had become notable people in the civilized world to the east of them by the break-up of Alexander’s empire. To the north of the Roman power were the Gauls; to the south of them were the Greek settlements of Magna Græcia, that is to say of Sicily and of the toe and heel of Italy. The Gauls were a hardy, warlike people and the Romans held that boundary by a line of forts and fortified settlements. The Greek cities in the south headed by Tarentum (now Taranto) and by Syracuse in Sicily, did not so much threaten as fear the Romans. They looked about for some help against these new conquerors. We have already told how the empire of Alexander fell to pieces and was divided among his generals and companions. Among these adventurers was a kinsman of Alexander’s named Pyrrhus, who established himself in Epirus, which is across the Adriatic Sea over against the heel of Italy. It was his ambition to play the part of Philip of Macedonia to Magna Græcia, and to become protector and master-general of Tarentum, Syracuse and the rest of that part of the world. He had what was then it very efficient modern army; he had an infantry phalanx, cavalry from Thessaly—which was now quite as good as the original Macedonian cavalry—and twenty fighting elephants; he invaded Italy and routed the Romans in two considerable battles, Heraclea (280 B.C.) and Ausculum (279 B.C.), and having driven them north, he turned his attention to the subjugation of Sicily.
