(3) COMITIA TRIBUTA. These assemblies likewise were called into existence by the constitution of Servius Tullius, who divided the Roman territory into thirty local tribes. It is a disputed question whether the patricians were originally included in these tribes; but, whether they were or not, it is certain, that by far the majority of the people in the tribes were plebeians, and that, consequently, the character of these assemblies was essentially plebeian. After the decemvirate, the patricians had certainly the right of voting in the assemblies of the tribes, which were then also convened by the higher magistrates. The assemblies of the tribes had originally only a local power; they were intended to collect the tributum, and to furnish the contingents for the army; they may further have discussed the internal affairs of each tribe, such as the making or keeping up of roads, wells, and the like. But their influence gradually increased, and they at length acquired the following powers:--1. _The election of the inferior magistrates_, whose office it was to protect the commonalty or to superintend the affairs of the tribes. Hence the tribunes of the plebs were elected in the comitia tributa. In like manner, the aediles were elected by them, though the curule aediles were elected at a different time from the plebeian aediles and under the presidency of a consul. At a still later time, the quaestors and tribunes of the soldiers, who had before been appointed by the consuls, were appointed in the assemblies of the tribes. The proconsuls to be sent into the provinces, and the prolongation of the imperium for a magistrate who was already in a province, were likewise points which were determined by the tribes in later times. The inferior magistrates elected by the tribes are:--the triumviri capitales, triumviri monetales, the curatores viarum, decemviri litibus judicandis, tribuni aerarii, magistri vicorum et pagorum, praefecti annonae, duumviri navales, quinqueviri muris turribusque reficiendis, triumviri coloniae deducendae, triumviri, quatuorviri, &c., mensarii, and lastly, after the Domitian law, B.C. 104, also the members of colleges of priests. The pontifex maximus had been elected by the people from an earlier time. 2. _The legislative power_ of the comitia tributa was at first very insignificant, for all they could do was to make regulations concerning the local affairs of the tribes. But after a time, when the tribes began to be the real representatives of the people, matters affecting the whole people also were brought before them by the tribunes, which, framed as resolutions, were laid before the senate, where they might either be sanctioned or rejected. This practice of the tributa comitia gradually acquired for them the right of taking the initiative in any measure, or the right of originating measures, until, in B.C. 449, this right was recognised and sanctioned by a law of L. Valerius Publicola and M. Horatius Barbatus.
