The termination of the struggles between the old and new burgesses, the various and comparatively successful endeavours to relieve the middle class, and the germs - already making their appearance amidst the newly acquired civic equality - of the formation of a new aristocratic and a new democratic party, have thus been passed in review. It remains that we describe the shape which the new government assumed amidst these changes, and the positions in which after the political abolition of the nobility the three elements of the republican commonwealth - the burgesses, the magistrates, and the senate - stood towards each other.

The burgesses in their ordinary assemblies continued as hitherto to be the highest authority in the commonwealth and the legal sovereign. But it was settled by law that - apart from the matters committed once for all to the decision of the centuries, such as the election of consuls and censors - voting by districts should be just as valid as voting by centuries: a regulation introduced as regards the patricio-plebeian assembly by the Valerio-Horatian law of 305[12] and extended by the Publilian law of 415, but enacted as regards the plebeian separate assembly by the Hortensian law about 467[13]. We have already noticed that the same individuals, on the whole, were entitled to vote in both assemblies, but that - apart from the exclusion of the patricians from the plebeian separate assembly - in the general assembly of the districts all entitled to vote were on a footing of equality, while in the centuriate comitia the working of the suffrage was graduated with reference to the means of the voters, and in so far, therefore, the change was certainly a levelling and democratic innovation. It was a circumstance of far greater importance that, towards the end of this period, the primitive freehold basis of the right of suffrage began for the first time to be called in question. Appius Claudius, the boldest innovator known in Roman history, in his censorship in 442 without consulting the senate or people so adjusted the burgess-roll, that a man who had no land was received into whatever tribe he chose and then according to his means into the corresponding century. But this alteration was too far in advance of the spirit of the age to obtain full acceptance. One of the immediate successors of Appius, Quintus Fabius Rullianus, the famous conqueror of the Samnites, undertook in his censorship of 450 not to set it aside entirely, but to confine it within such limits that the real power in the burgess-assemblies should continue to be vested in the holders of land and of wealth. He assigned those who had no land collectively to the four city tribes, which were now made to rank not as the first but as the last. The rural tribes, on the other hand, the number of which gradually increased between 367 and 513 from seventeen to thirty-one - thus forming a majority, greatly preponderating from the first and ever increasing in preponderance, of the voting-divisions - were reserved by law for the whole of the burgesses who were freeholders. In the centuries the equalization of the freeholders and non-freeholders remained as Appius had introduced it. In this manner provision was made for the preponderance of the freeholders in the comitia of the tribes, while for the centuriate comitia in themselves the wealthy already turned the scale. By this wise and moderate arrangement on the part of a man who for his warlike feats and still more for this peaceful achievement justly received the surname of the Great (Maximus), on the one hand the duty of bearing arms was extended, as was fitting, also to the non-freehold burgesses; on the other hand care was taken that their influence, especially that of those who had once been slaves and who were for the most part without property in land, should be subjected to that check which is unfortunately, in a state allowing slavery, an indispensable necessity. A peculiar moral jurisdiction, moreover, which gradually came to be associated with the census and the making up of the burgess-roll, excluded from the burgess-body all individuals notoriously unworthy, and guarded the full moral and political purity of citizenship.

The powers of the comitia exhibited during this period a tendency to enlarge their range, but in a manner very gradual. The increase in the number of magistrates to be elected by the people falls, to some extent, under this head; it is an especially significant fact that from 392 the military tribunes of one legion, and from 443 four tribunes in each of the first four legions respectively, were nominated no longer by the general, but by the burgesses. During this period the burgesses did not on the whole interfere in administration; only their right of declaring war was, as was reasonable, emphatically maintained, and held to extend also to cases in which a prolonged armistice concluded instead of a peace expired and what was not in law but in fact a new war began (327). In other instances a question of administration was hardly submitted to the people except when the governing authorities fell into collision and one of them referred the matter to the people - as when the leaders of the moderate party among the nobility, Lucius Valerius and Marcus Horatius, in 305, and the first plebeian dictator, Gaius Marcius Rutilus, in 398, were not allowed by the senate to receive the triumphs they had earned; when the consuls of 459 could not agree as to their respective provinces of jurisdiction; and when the senate, in 364, resolved to give up to the Gauls an ambassador who had forgotten his duty, and a consular tribune carried the matter to the community. This was the first occasion on which a decree of the senate was annulled by the people; and heavily the community atoned for it. Sometimes in difficult cases the government left the decision to the people, as first, when Caere sued for peace, after the people had declared war against it but before war had actually begun (401); and at a subsequent period, when the senate hesitated to reject unceremoniously the humble entreaty of the Samnites for peace (436). It is not till towards the close of this epoch that we find a considerably extended intervention of the comitia tributa in affairs of administration, particularly through the practice of consulting it as to the conclusion of peace and of alliances: this extension probably dates from the Hortensian law of 467.

But notwithstanding these enlargements of the powers of the burgess-assemblies, their practical influence on state affairs began, particularly towards the close of this period, to wane.  First of all, the extension of the bounds of Rome deprived her primary assembly of its true basis. As an assembly of the freeholders of the community, it formerly might very well meet in sufficiently full numbers, and might very well know its own wishes, even without discussion; but the Roman burgess-body had now become less a civic community than a state. The fact that those dwelling together voted also with each other, no doubt, introduced into the Roman comitia, at least when the voting was by tribes, a sort of inward connection and into the voting now and then energy and independence; but under ordinary circumstances the composition of the comitia and their decision were left dependent on the person who presided or on accident, or were committed to the hands of the burgesses domiciled in the capital. It is, therefore, quite easy to understand how the assemblies of the burgesses, which had great practical importance during the first two centuries of the republic, gradually became a mere instrument in the hands of the presiding magistrate, and in truth a very dangerous instrument, because the magistrates called to preside were so numerous, and every resolution of the community was regarded as the ultimate legal expression of the will of the people.  But the enlargement of the constitutional rights of the burgesses was not of much moment, inasmuch as these were less than formerly capable of a will and action of their own, and there was as yet no demagogism, in the proper sense of that term, in Rome. Had any such demagogic spirit existed, it would have attempted not to extend the powers of the burgesses, but to remove the restrictions on political debate in their presence; whereas throughout this whole period there was undeviating acquiescence in the old maxims, that the magistrate alone could convoke the burgesses, and that he was entitled to exclude all debate and all proposal of amendments. At the time this incipient breaking up of the constitution made itself felt chiefly in the circumstance that the primary assemblies assumed an essentially passive attitude, and did not on the whole interfere in government either to help or to hinder it.
