From the fourth or third century until the beginning of the first century bc, Rome’s armies were also the armies of her allies. The socii and nomen Latinum raised at least half of the soldiers that fought wars for Rome. The Italic allies were clearly distinguished from the non-Italic troops, such as Cretan archers or Numidian horsemen, by the fact that they were governed by the formula togatorum. This can be concluded from their
‘definition’in the lex agraria from 111 bc: socii nominisve Latini quibus ex formula togatorum milites in terra Italia imperare solent. The formula togatorum is seen as a defining element, distinguishing the Latin and Italic peoples from Rome’s overseas allies. Although in the second century bc a consciousness of Italy as a political and cultural unity gradually emerged, it was still referred to as a military alliance of Roman citizens and allies at the end of that century. 1 The beginnings of this system remain in the dark, due to the inadequacies of our sources. The foedus Cassianum between Rome and the Latin League (traditionally dated to 493 bc) supposedly established a federal army under Roman command, but next to nothing is known about its functioning. The participation of the allied peoples was based on the treaties between their communities and Rome. The position of the Latin colonies was slightly different, because their obligations were probably based on the lex coloniae governing each Latin colony. 2 We may assume that the role of the allies was re-defined
