for ancient and recent wrongs, had already in 471 annihilated the
Celtic Senones; in the south, through the great war from 490 to 513,
it had dislodged the Phoenicians from the island of Sicily. In the
north there belonged to the combination headed by Rome the Latin town
of Ariminum (besides the burgess-settlement of Sena), in the south the
community of the Mamertines in Messana, and as both were nationally of
Italian origin, so both shared in the common rights and obligations of
the Italian confederacy. It was probably the pressure of events at
the moment rather than any comprehensive political calculation, that
gave rise to these extensions of the confederacy; but it was natural
that now at least, after the great successes achieved against
Carthage, new and wider views of policy should dawn upon the Roman
government--views which even otherwise were obviously enough suggested
by the physical features of the peninsula. Alike in a political and
in a military point of view Rome was justified in shifting its
northern boundary from the low and easily crossed Apennines to the
mighty mountain-wall that separates northern from southern Europe,
the Alps, and in combining with the sovereignty of Italy the
sovereignty of the seas and islands on the west and east of the
peninsula; and now, when by the expulsion of the Phoenicians from
Sicily the most difficult portion of the task had been already
achieved, various circumstances united to facilitate its completion
by the Roman government.

Sicily a Dependency of Italy

In the western sea which was of far more account for Italy than the
Adriatic, the most important position, the large and fertile island
of Sicily copiously furnished with harbours, had been by the peace
with Carthage transferred for the most part into the possession of the
