Dominance of the Western Mediterranean.
Carthage contested with Rome for control of the Western Mediterranean, and with the Carthaginians sold into slavery at the end of the Third Punic War, it had no real opposition. And as Macedonia had supported Carthage in the Second Punic War, Rome had a good excuse to enter into the Eastern Mediterranean to punish it.

It fought against Carthage for control of the Western Mediterranean. Rome did not fight against or with Sicilians. The First Punic war was fought against the Carthaginians who had settlements in the west of Sicily. Rome's aim at the beginning of the war was to gain control over Sicily. In this war Syracuse allied with Rome. However, the Syracusans were Greeks, not Sicilian. The indigenous Sicilians were mostly annexed or caught in fights between Greeks and Carthaginian and then got caught in Rome's war. The fight over control of the western Mediterranean occurred in the Second Punic war. Rome's seizing of Sardinia and Corsica (a result following the first war, rather than an original aim of the first war) most likely contributed to this. The second war was provoked by the Carthaginians, and it ended with Rome controlling the western mediterranean.
Upon the defeat of Carthage the Romans won complete control of the western Mediterranean Sea.
Rome grew from a small town on the Tiber River to become a great power. Rome conquered Greece, Mesopotamia, Egypt, and Persia. Rome's central location and good climate were factors in its success. Because most of Italy is surrounded by water, Romans could easily travel by sea. The mountains in the north made it difficult to travel over land. The warm dry weather resulted in high crop yields, so the Romans had plenty of food.
