In one way, pre-Roman Italy was quite a lot like Greece: it consisted of a bunch of independent urban communities situated on the decent farming land (that is the lowlands), with a number of less-urban tribal polities stretching over the less-farming-friendly uplands. While pre-Roman urban communities weren’t exactly like the Greek polis, they were fairly similar. Greek colonization beginning in the eighth century added actual Greek poleis to the Italian mix and frankly they fit in just fine. On the flip side, there were the Samnites, a confederation of tribal communities with some smaller towns occupying mostly rough uplands not all that dissimilar to the Greek Aetolians, a confederation of tribal communities and smaller towns occupying mostly rough uplands.

In one very important way, pre-Roman Italy was very much not like Greece: whereas in Greece all of those communities shared a single language, religion and broad cultural context, Roman Italy was a much more culturally complex place. Consequently, as the Romans slowly absorbed pre-Roman Italy into the Roman Italy of the Republic, that meant managing the truly wild variety of different peoples in their alliance system. Let’s quickly go through them all, moving from North to South.

The Romans called the region south of the Alps but north of the Rubicon River Cisalpine Gaul and while we think of it as part of Italy, the Romans did not. That said, Gallic peoples had pushed into Italy before and a branch of the Senones occupied the lands between Ariminum and Ancona. Although Gallic peoples were always a factor in Italy, the Romans don’t seem to have incorporated their communities as socii; indeed the Romans were generally at their most ruthless when it came to interactions with Gallic peoples (despite the tendency to locate the “unassimilable” people on the Eastern edge of Rome’s empire, it was in fact the Gauls that the Romans most often considered in this way, though as we will see, wrongly so). That’s not to say that there was no cultural contact, of course; the Romans ended up adopting almost all of the Gallic military equipment set, for instance. In any event, it wouldn’t be until the late first century BCE that Cisalpine Gaul was merged into Italy proper, so we won’t deal too much with the Gauls just yet. I do want to note that, when we are thinking about the diversity of the place, even to speak of “the Gauls” is to be terribly reductive, as we are really thinking of at least half a dozen different Gallic peoples (Senones, Boii, Inubres, Lingones, etc) along with the Ligures and the Veneti, who may have been blends of Gallic and Italic peoples (though we are more poorly informed about both than we’d like).

Moving south then, we first meet the Etruscans, who we’ve already discussed, their communities – independent cities joined together in defensive confederations before being converted into allies of the Romans – clustered on north-western coast of Italy. They had a language entirely unrelated to Latin – or indeed, any other known language – and their own unique religion and culture. The Romans adopted some portions of that culture (in particular the religious practices) but the Etruscans remained distinct well into the first century. While a number of Etruscan communities backed the Samnites in the Third Samnite War (298-290 BC) culminating in the Battle of Sentinum (295) as a last-ditch effort to prevent Roman hegemony over the peninsula, the Etruscans subsequently remained quite loyal to Rome, holding with the Romans in both the Second Punic and Social Wars. It is important to keep in mind that while we tend to talk about “the Etruscans” (as the Romans sometimes do) they would have thought of themselves first through their civic identity, as Perusines, Clusians, Populinians and so on (much like their Greek contemporaries).

Moving further south, we have the peoples of the Apennines (the mountain range that cuts down the center of Italy). The people of the northern Apennines were the Umbri (that is, Umbrian speakers), though this linguistic classification hides further cultural and political differences. We’ve met the Sabines – one such group, but there were also the Volsci and Marsi (the latter particularly well known for being hard fighters as allies to Rome; Appian reports that the Marsi had a saying prior to the Social War, “No Triumph against the Marsi nor without the Marsi”). Further south along the Apennines were the Oscan speakers, most notably the Samnites (who resisted the Romans most strongly) but also the Lucanians and Paelignians (the latter also get a reputation for being hard fighters, particularly in Livy). The Umbrian and Oscan language families are related (though about as different from each other as Italian from Spanish; they and Latin are not generally mutually intelligible) and there does seem to have been some cultural commonality between these two large groups, but also a lot of differences. Their religion included a number of practices and gods unknown to the Romans, some later adopted (Oscan Flosa adapted as Latin Flora, goddess of flowers) and some not (e.g. the “Sacred Spring” rite, Strabo 5.4.12).

Also Oscan speakers, the Campanians settled in Campania (surprise!) at some early point (perhaps around 1000-900 BC) and by the fifth century were living in urban communities politically more similar to Latium and Etruria (or Greece, which will make sense in a moment) than their fellow Oscan speakers in the hills above, to the point that the Campanians turned to Rome to aid them against the also-Oscan-speaking Samnites. The leading city of the Campanians was Capua, but as Fronda (op. cit.) notes, they were meaningful divisions among them; Capua’s very prominence meant that many of the other Campanians were aligned against it, a division the Romans exploited.

The Oscans struggled for territory in Southern Italy with the Greeks – told you we’d get to them. The Greeks founded colonies along the southern part of Italy, expelling or merging with the local inhabitants beginning in the seventh century. These Greek colonies have distinctive material culture (though the Italic peoples around them often adopted elements of it they found useful), their own language (Greek), and their own religion. I want to stress here that Greek religion is not equivalent to Roman religion, to the point that the Romans are sticklers about which gods are worshipped with Roman rites and which are worshipped with the ritus graecus (“Greek rites”) which, while not a point-for-point reconstruction of Greek rituals, did involve different dress, different interpretations of omens, and so on.

All of these peoples (except the Gauls) ended up in Rome’s alliance system, fighting as socii in Rome’s wars. The point of all of this is that this wasn’t an alliance between, say, the Romans and the “Italians” with the latter being really quite a lot like the Romans except not being from Rome. Rather, Rome had constructed a hegemony (an “alliance” in name only, as I hope we’ve made clear) over (::deep breath::) Latins, Romans, Etruscans, Sabines, Volsci, Marsi, Lucanians, Paelignians, Samnites, Campanians, and Greeks, along with some people we didn’t mention (the Falisci, Picenes – North and South, Opici, Aequi, Hernici, Vestini, etc.). Many of these groups can be further broken down – the Samnites consisted of five different tribes in a confederation, for instance.

In short, Roman Italy under the Republic was preposterously multicultural (in the literal meaning of that word) … and it turns out that’s why they won.
