The goal was thus attained. After four years of war the Pontic king was again a client of the Romans, and a single and settled government was re-established in Greece, Macedonia, and Asia Minor; the requirements of interest and honour were satisfied, if not adequately, yet so far as circumstances would allow; Sulla had not only brilliantly distinguished himself as a soldier and general, but had the skill, in his path crossed by a thousand obstacles, to preserve the difficult mean between bold perseverance and prudent concession. Almost like Hannibal he had fought and conquered, in order that with the forces, which the first victory gave him, he might prepare forthwith for a second and severer struggle. After he had in some degree compensated his soldiers for the fatigues which they had undergone by luxurious winter-quarters in the rich west of Asia Minor, he in the spring of 671 transferred them in 1600 vessels from Ephesus to the Piraeeus and thence by the land route to Patrae, where the vessels again lay ready to convey the troops to Brundisium. His arrival was preceded by a report addressed to the senate respecting his campaigns in Greece and Asia, the writer of which appeared to know nothing of his deposition; it was the mute herald of the impending restoration.

This state of suspense and uncertainty existing in Italy when Sulla took his departure for Greece in the beginning of 667 has been already described: the half-suppressed insurrection, the principal army under the more than half-usurped command of a general whose politics were very doubtful, the confusion and the manifold activity of intrigue in the capital. The victory of the oligarchy by force of arms had, in spite or because of its moderation, engendered manifold discontent. The capitalists, painfully affected by the blows of the most severe financial crisis which Rome had yet witnessed, were indignant at the government on account of the law which it had issued as to interest, and on account of the Italian and Asiatic wars which it had not prevented.

The insurgents, so far as they had laid down their arms, bewailed not only the disappointment of their proud hopes of obtaining equal rights with the ruling burgesses, but also the forfeiture of their venerable treaties, and their new position as subjects utterly destitute of rights. The communities between the Alps and the Po were likewise discontented with the partial concessions made to them, and the new burgesses and freedmen were exasperated by the cancelling of the Sulpician laws. The populace of the city suffered amid the general distress, and found it intolerable that the government of the sabre was no longer disposed to acquiesce in the constitutional rule of the bludgeon. The adherents, resident in the capital, of those outlawed after the Sulpician revolution - adherents who remained very numerous in consequence of the remarkable moderation of Sulla - laboured zealously to procure permission for the outlaws to return home; and in particular some ladies of wealth and distinction spared for this purpose neither trouble nor money. None of these grounds of ill-humour were such as to furnish any immediate prospect of a fresh violent collision between the parties; they were in great part of an aimless and temporary nature; but they all fed the general discontent, and had already been more or less concerned in producing the murder of Rufus, the repeated attempts to assassinate Sulla, the issue of the consular and tribunician elections for 667 partly in favour of the opposition.

The name of the man whom the discontented had summoned to the head of the state, Lucius Cornelius Cinna, had been hitherto scarcely heard of, except so far as he had borne himself well as an officer in the Social war. We have less information regarding the personality and the original designs of Cinna than regarding those of any other party leader in the Roman revolution. The reason is, to all appearance, simply that this man, altogether vulgar and guided by the lowest selfishness, had from the first no ulterior political plans whatever. It was asserted at his very first appearance that he had sold himself for a round sum of money to the new burgesses and the coterie of Marius, and the charge looks very credible; but even were it false, it remains nevertheless significant that a suspicion of the sort, such as was never expressed against Saturninus and Sulpicius, attached to Cinna.

In fact the movement, at the head of which he put himself, has altogether the appearance of worthlessness both as to motives and as to aims. It proceeded not so much from a party as from a number of malcontents without proper political aims or notable support, who had mainly undertaken to effect the recall of the exiles by legal or illegal means. Cinna seems to have been admitted into the conspiracy only by an afterthought and merely because the intrigue, which in consequence of the restriction of the tribunician powers needed a consul to bring forward its proposals, saw in him among the consular candidates for 667 its fittest instrument and so pushed him forward as consul. Among the leaders appearing in the second rank of the movement were some abler heads; such was the tribune of the people Gnaeus Papirius Carbo, who had made himself a name by his impetuous popular eloquence, and above all Quintus Sertorius, one of the most talented of Roman officers and a man in every respect excellent, who since his candidature for the tribunate of the people had been a personal enemy to Sulla and had been led by this quarrel into the ranks of the disaffected to which he did not at all by nature belong. The proconsul Strabo, although at variance with the government, was yet far from going along with this faction.

So long as Sulla was in Italy, the confederates for good reasons remained quiet. But when the dreaded proconsul, yielding not to the exhortations of the consul Cinna but to the urgent state of matters in the east, had embarked, Cinna, supported by the majority of the college of tribunes, immediately submitted the projects of law which had been concerted as a partial reaction against the Sullan restoration of 666. They embraced the political equalization of the new burgesses and the freedmen, as Sulpicius had proposed it, and the restitution of those who had been banished in consequence of the Sulpician revolution to their former status.

The new burgesses flocked en masse to the capital, that along with the freedmen they might terrify, and in case of need force, their opponents into compliance. But the government party was determined not to yield, consul stood against consul, Gnaeus Octavius against Lucius Cinna, and tribune against tribune; both sides appeared in great part armed on the day and at the place of voting. The tribunes of the senatorial party interposed their veto; when swords were drawn against them even on the rostra, Octavius employed force against force. His compact bands of armed men not only cleared the Via Sacra and the Forum, but also, disregarding the commands of their more gentle-minded leader, exercised horrible atrocities against the assembled multitude. The Forum swam with blood on this "Octavius' day", as it never did before or afterwards - the number of corpses was estimated at ten thousand. Cinna called on the slaves to purchase freedom for themselves by sharing in the struggle; but his appeal was as unsuccessful as the like appeal of Marius in the previous year, and no course was left to the leaders of the movement but to take flight. The constitution supplied no means of proceeding farther against the chiefs of the conspiracy, so long as their year of office lasted. But a prophet presumably more loyal than pious had announced that the banishment of the consul Cinna and of the six tribunes of the people adhering to him would restore peace and tranquillity to the country; and, in conformity not with the constitution but with this counsel of the gods fortunately laid hold of by the custodiers of oracles, the consul Cinna was by decree of the senate deprived of his office, Lucius Cornelius Merula was chosen in his stead, and outlawry was pronounced against the chiefs who had fled. It seemed as if the whole crisis were about to end in a few additions to the number of the men who were exiles in Numidia.
