Dissolution of National Leagues-- Furnishing of Contingents
As a general rule, it may be taken for granted that not only the Latin and Hernican national confederations--as to which the fact is expressly stated--but all such confederations subsisting in Italy, and the Samnite and Lucanian leagues in particular, were legally dissolved or at any rate reduced to insignificance, and that in general no Italian community was allowed the right of acquiring property or of intermarriage, or even the right of joint consultation and resolution, with any other.
Further, provision must have been made, under different forms, for placing the military and financial resources of all the Italian communities at the disposal of the leading community. Although the burgess militia on the one hand, and the contingents of the "Latin name" on the other, were still regarded as the main and integral constituents of the Roman army, and in that way its national character was on the whole preserved, the Roman -cives sine suffragio- were called forth to join its ranks, and not only so, but beyond doubt the non-Latin federate communities also were either bound to furnish ships of war, as was the case with the Greek cities, or were placed on the roll of contingent-furnishing Italians (-formula togatorum-), as must have been ordained at once or gradually in the case of the Apulians, Sabellians, and Etruscans.
In general this contingent, like that of the Latin communities, appears to have had its numbers definitely fixed, although, in case of necessity, the leading community was not precluded from making a larger requisition. This at the same time involved an indirect taxation, as every community was bound itself to equip and to pay its own contingent. Accordingly it was not without design that the supply of the most costly requisites for war devolved chiefly on the Latin, or non-Latin federate communities; that the war marine was for the most part kept up by the Greek cities; and that in the cavalry service the allies, at least subsequently, were called upon to furnish a proportion thrice as numerous as the Roman burgesses, while in the infantry the old principle, that the contingent of the allies should not be more numerous than the burgess army, still remained in force for a long time at least as the rule.
