Rome defeats Latin League
As Rome got involved with Campania as protector of Capua, the Latin cities, which had been chafing under the Roman yoke for quite some time, broke into open revolt. The rebellion of the Latins stranded the Roman Legions in Campania. They could only get home by beating the Latin armies that stood between them and their home city. They were able to do that. One consequence of the Roman victory was the dissolution of the Latin League. It was transformed from an independent political federation into a religious association. This meant that the limit on troop levies and share of war spoils were also dissolved. The agreement between Rome and the League was replaced by a series of bilateral agreements between Rome and the individual Latin cities that once comprised the League. Also, some of the Latin towns were forced to cede some of their territory to Rome. Some towns, such as Antium and Tarracina, were given full local autonomy with their leading citizens losing a good portion of their land and being replaced by Roman colonists. Many of the towns—Lanuvium, Aricia, Momentum, Pedum—became Roman citizen communities after the model of Tusculum. The walls of Velitrae were demolished, its Senate ejected and resettled in the middle of Etruria. The land of the Senators was confiscated and given to Roman citizens.
Another consequence of the Latin League revolt would be the building of the first consular road, the Via Appia, later in the century. It would skirt the Latin lands and allow the Roman army direct access to the Campanian plain.
