Lastly, with this military administrative union of the whole peoples dwelling to the south of the Apennines, as far as the Iapygian promontory and the straits of Rhegium, was connected the rise of a new name common to them all--that of "the men of the toga" (-togati-), which was their oldest designation in Roman state law, or that of the "Italians," which was the appellation originally in use among the Greeks and thence became universally current. The various nations inhabiting those lands were probably first led to feel and own their unity, partly through their common contrast to the Greeks, partly and mainly through their common resistance to the Celts; for, although an Italian community may now and then have made common cause with the Celts against Rome and employed the opportunity to recover independence, yet in the long run sound national feeling necessarily prevailed. As the "Gallic field" down to a late period stood contrasted in law with the Italian, so the "men of the toga" were thus named in contrast to the Celtic "men of the hose" (-braccati-); and it is probable that the repelling of the Celtic invasions played an important diplomatic part as a reason or pretext for centralizing the military resources of Italy in the hands of the Romans. Inasmuch as the Romans on the one hand took the lead in the great national struggle and on the other hand compelled the Etruscans, Latins, Sabellians, Apulians, and Hellenes (within the bounds to be immediately described) alike to fight under their standards, that unity, which hitherto had been undefined and latent rather than expressed, obtained firm consolidation and recognition in state law; and the name -Italia-, which originally and even in the Greek authors of the fifth century--in Aristotle for instance--pertained only to the modern Calabria, was transferred to the whole land of these wearers of the toga. Earliest Boundaries of the Italian Confederacy The earliest boundaries of this great armed confederacy led by Rome, or of the new Italy, reached on the western coast as far as the district of Leghorn south of the Arnus,(44) on the east as far as the Aesis north of Ancona. The townships colonized by Italians, lying beyond these limits, such as Sena Gallica and Ariminum beyond the Apennines, and Messana in Sicily, were reckoned geographically as situated out of Italy--even when, like Ariminum, they were members of the confederacy or even, like Sena, were Roman burgess communities. Still less could the Celtic cantons beyond the Apennines be reckoned among the -togati-, although perhaps some of them were already among the clients of Rome.
