The revolt ran through the peninsula like the flame through the steppe.

The brave and numerous people of the Marsians took the lead, in connection with the small but hardy confederacies in the Abruzzi--the Paeligni, Marrucini, Frentani, and Vestini.
The brave and sagacious Quintus Silo, already mentioned, was here the soul of the movement.

The Marsians were the first formally to declare against the Romans, whence the war retained afterwards the name of the Marsian war.

The example thus given was followed by the Samnite communities, and generally by the mass of the communities from the Liris and the Abruzzi down to Calabria and Apulia; so that all Central and Southern Italy was soon in arms against Rome.
Italians Friendly to Rome The Etruscans and Umbrians on the other hand held by Rome, as they had already taken part with the equites against Drusus.( 10) It is a significant fact, that in these regions the landed and moneyed aristocracy had from ancient times preponderated and the middle class had totally disappeared, whereas among and near the Abruzzi the farmer-class had preserved its purity and vigour better than anywhere else in Italy: it was from the farmers accordingly and the middle class in general that the revolt substantially proceeded, whereas the municipal aristocracy still went hand in hand with the government of the capital.

This also readily explains the fact, that there were in the insurgent districts isolated communities, and in the insurgent communities minorities, adhering to the Roman alliance; the Vestinian town Pinna, for instance, sustained a severe siege for Rome, and a corps of loyalists that was formed in the Hirpinian country under Minatius Magius of Aeclanum supported the Roman operations in Campania.
Lastly, there adhered to Rome the allied communities of best legal position--in Campania Nola and Nuceria and the Greek maritime towns Neapolis and Rhegium, and in like manner at least most of the Latin colonies, such as Alba and Aesernia--just as in the Hannibalic war the Latin and Greek towns on the whole had taken part with, and the Sabellian towns against, Rome.
