Original Equality of Rights between Rome and Latium
The nature of a hegemony implies that it becomes gradually converted into sovereignty by the mere inward force of circumstances; and the Roman hegemony over Latium formed no exception to the rule. It was based upon the essential equality of rights between the Roman state on the one side and the Latin confederacy on the other;(1) but at least in matters of war and in the treatment of the acquisitions thereby made this relation between the single state on the one hand and the league of states on the other virtually involved a hegemony.
1. Cf. I. VII. Relation of Rome to Latium
According to the original constitution of the league not only was the right of making wars and treaties with foreign states--in other words, the full right of political self-determination--reserved in all probability both to Rome and to the individual towns of the Latin league; and when a joint war took place, Rome and Latium probably furnished the like contingent, each, as a rule, an "army" of 8400 men;(2) but the chief command was held by the Roman general, who then nominated the officers of the staff, and so the leaders-of-division (-tribuni militum-), according to his own choice.
2. The original equality of the two armies is evident from Liv. i. 52; viii. 8, 14, and Dionys. viii, 15; but most clearly from Polyb. vi. 26.
In case of victory the moveable part of the spoil, as well as the conquered territory, was shared between Rome and the confederacy; when the establishment of fortresses in the conquered territory was resolved on, their garrisons and population were composed partly of Roman, partly of confederate colonists; and not only so, but the newly-founded community was received as a sovereign federal state into the Latin confederacy and furnished with a seat and vote in the Latin diet.
