His powerful voice, his lively gestures sometimes bordering on theatrical display, the luxuriant copiousness of his flow of words arrested, even if they did not convince, his hearers. As a partisan he was from the outset on the side of the senate, and his first public appearance (659) had been the impeachment of Norbanus who was mortally hated by the government party[22]. Among the conservatives he belonged to the section of Crassus and Drusus. We do not know what primarily gave occasion to his soliciting the tribuneship of the people for 666, and on its account renouncing his patrician nobility; but he seems to have been by no means rendered a revolutionist through the fact that he, like the whole middle party, had been persecuted as revolutionary by the conservatives, and to have by no means intended an overthrow of the constitution in the sense of Gaius Gracchus.

It would rather seem that, as the only man of note belonging to the party of Crassus and Drusus who had come forth uninjured from the storm of the Varian prosecutions, he felt himself called on to complete the work of Drusus and finally to set aside the still subsisting disabilities of the new burgesses - for which purpose he needed the tribunate. Several acts of his even during his tribuneship are mentioned, which betray the very opposite of demagogic designs. For instance, he prevented by his veto one of his colleagues from cancelling through a decree of the people the sentences of jurymen issued under the Varian law; and when the late aedile Gaius Caesar, passing over the praetorship, unconstitutionally became a candidate for the consulship for 667, with the design, it was alleged, of getting the charge of the Asiatic war afterwards entrusted to him, Sulpicius opposed him more resolutely and sharply than any one else. Entirely in the spirit of Drusus, he thus demanded from himself as from others primarily and especially the maintenance of the constitution.

But in fact he was as little able as was Drusus to reconcile things that were incompatible, and to carry out in strict form of law the change of the constitution which he had in view - a change judicious in itself, but never to be obtained from the great majority of the old burgesses by amicable means. His breach with the powerful family of the Julii - among whom in particular the consular Lucius Caesar, the brother of Gaius, was very influential in the senate - and withthesectionof the aristocracy adhering to it, beyond doubt materially cooperated and carried the irascible man through personal exasperation beyond his original design.

Yet the proposals brought in by him were of such a nature as to be by no means out of keeping with the personal character and the previous party-position of their author. The equalization of the new burgesses with the old was simply a partial resumption of the proposals drawn up by Drusus in favour of the Italians; and, like these, only carried out the requirements of a sound policy.

The recall of those condemned by the Varian jurymen no doubt sacrificed the principle of the inviolability of such a sentence, in defence of which Sulpicius himself had just practically interposed; but it mainly benefited in the first instance the members of the proposer's own party, the moderate conservatives, and it may be very well conceived that so impetuous a man might when first coming forward decidedly combat such a measure and then, indignant at the resistance which he encountered, propose it himself. The measure against the insolvency of senators was doubtless called forth by the exposure of the economic condition of the ruling families - so deeply embarrassed notwithstanding all their outward splendour - on occasion of the last financial crisis. It was painful doubtless, but yet of itself conducive to the rightly understood interest of the aristocracy, if, as could not but be the effect of the Sulpician proposal, all individuals should withdraw from the senate who were unable speedily to meet their liabilities, and if the coterie-system, which found its main support in the insolvency of many senators and their consequent dependence on their wealthy colleagues, should be checked by the removal of the notoriously venal pack of the senators. At the same time, of course, we do not mean to deny that such a purification of the senate-house so abruptly and invidiously exposing the senate, as Rufus proposed, would certainly never have been proposed without his personal quarrels with the ruling coterie-heads. Lastly, the regulationin favour of the freedmen had undoubtedly for its primary object to make its proposer master of the street; but in itself it was neither unwarranted nor incompatible with the aristocratic constitution. Since the freedmen had begun to be drawn upon for military service, their demand for the right of voting was so far justified, as the right of voting and the obligation of service had always gone hand in hand. Moreover, looking to the nullity of the comitia, it was politically of very little moment whether one sewer more emptied itself into that slough. The difficulty which the oligarchy felt in governing with the comitia was lessened rather than increased by the unlimited admission of the freedmen, who were to a very great extent personally and financially dependent on the ruling families and, if rightly used, might quite furnish the government with a means of controlling the elections more thoroughly than before.

This measure certainly, like every other political favour shown to the proletariate, ran counter to the tendencies of the aristocracy friendly to reform; but it was for Rufus hardly anything else than what the corn-law had been for Drusus - a means of drawing the proletariate over to his side and of breaking down with its aid the opposition against the truly beneficial reforms which he meditated. It was easy to foresee that this opposition would not be slight; that the narrow-minded aristocracy and the narrow-minded bourgeoisie would display the same stupid jealousy after the subduing of the insurrection as they had displayed before its outbreak; that the great majority of all parties would secretly or even openly characterize the partial concessions made at the moment of the most formidable danger as unseasonable compliances, and would passionately resist every attempt to extend them. The example of Drusus had shown what came of undertakingto carry conservative reforms solely in reliance on the majority of the senate; it was a course quite intelligible, that his friend who shared his views should attempt to carry out kindred designs in opposition to that majority and under the forms of demagogism. Rufus accordingly gave himself no trouble to gain the senate over to his views by the bait of the jury courts. He found a better support in the freedmen and above all in the armed retinue - consisting, according to the report of his opponents, of 3000 hired men and an "opposition-senate" of 600 young men from the better class - with which he appeared in the streets and in the Forum.

His proposals accordingly met with the most decided resistance from the majority of the senate, which first, to gain time, induced the consuls Lucius Cornelius Sulla and Quintus Pompeius Rufus, both declared opponents of demagogism, to enjoin extraordinary religious observances, during which the popular assemblies were suspended. Sulpicius replied by a violent tumult, in which among other victims the young Quintus Pompeius, son of the one and son-in-law of the other consul, met his death and the lives of both consuls themselves were seriously threatened - Sulla is said even to have escaped only by Marius opening to him his house. They were obliged to yield; Sulla agreed to countermand the announced solemnities, and the Sulpician proposals now passed without further difficulty. But this was far from determining their fate. Though the aristocracy in the capital might own its defeat, there was now - for the first time since the commencement of the revolution - yet another power in Italy which could not be overlooked, viz. the two strong and victorious armies of the proconsul Strabo and the consul Sulla. The political position of Strabo might be ambiguous, but Sulla, although he had given way to open violence for the moment, was on the best terms with the majority of the senate; and not only so, but he had, immediately after countermanding the solemnities, departed for Campania to join his army. To terrify the unarmed consul by bludgeon-men or the defenceless capital by the swords of the legions, amounted to the same thing in the end: Sulpicius assumed that his opponent, now when he could, would requite violence with violence and return to the capital at the head of his legions to overthrow the conservative demagogue and his laws along with him. Perhaps he was mistaken. Sulla was just as eager for the war against Mithradates as he was probably averse to the political exhalations of the capital; considering his original spirit of indifference and his unrivalled political nonchalance, there is great probability that he by no means intended the coup d'etat which Sulpicius expected, and that, if he had been let alone, he would have embarked without delay with his troops for Asia so soon as he had captured Nola, with the siege of which he was still occupied.
