Such was the origin of the anomalous power of this man, who was not even a senator—a power which was the result of the weakness of Tiberius and of the fierce discords which divided the aristocracy; and it was a power which must of necessity prove disastrous, especially to the party of Agrippina and Germanicus. Although indications are not lacking that there was no great harmony or friendship between Sejanus and Drusus, it is evident that Sejanus, as the energetic representative of the interests of Tiberius, must have directed all his efforts against the friends of Agrippina, who was arousing the fiercest opposition to the emperor. But in the year 23, an unforeseen event seemed suddenly to change the situation and to render possible a reconciliation between Tiberius and the party of Agrippina. In this year, Drusus also, like so many other members of his family, died prematurely, at the age of thirty-eight, and on this occasion, for the time being, at least, no one raised the cry of poisoning. This unexpected misfortune moved Tiberius profoundly, for he dearly loved his son, and it seemed for a moment to determine the triumph of Agrippina's party. Now that his son had been taken from him, where, if not among the sons of Germanicus and Agrippina, could Tiberius look for a successor? And, as a further proof that Tiberius desired as far as possible to avoid conflict in the bosom of his family, he did not hesitate a moment, despite all the annoyances and difficulties which he had suffered at the hands of Agrippina and her friends. He officially recognized that in the sons of Germanicus were henceforth placed the future hopes of his family and of the empire. Of the two elder, Nero was now sixteen and Drusus was somewhat younger, though we do not know his exact age. These he summoned to appear before the senate, and he presented them to the assembly with a noble discourse the substance of which Tacitus has preserved for us, exhorting the youths and the senate to fulfil their respective duties for the greatness and the prosperity of the republic.

After the death of Drusus, therefore, a reconciliation became possible in the family of the Caesars. The latent rivalry between the families of Tiberius and Germanicus was extinguished. Indeed, even in the midst of the tears shed for the early death of Drusus, a gleam of concord seems to have shone down upon the house desolated by many tragedies, while Sejanus, whose power depended upon the strife of the factions, was for a moment set aside and driven back into the shadows. But it was not to continue long; for soon the flames of discord broke out more violently than ever. Whom shall we blame, Sejanus or Agrippina? Tacitus says that it was the fault of Sejanus, whom he accuses of having tried to destroy the descendants of Germanicus, in order to usurp their place: but he himself is forced to admit in another passage (Annals iv., 59) that virtually a little court of freedmen and dependents gathered about Nero, the leader of the sons of Germanicus, urging him on against Tiberius and Sejanus, and begging him to act quickly. "This," they said, "is the will of the people, the desire of the armies. Nor would Sejanus, who was even then making light of the patience of the old man and of the dilatoriness of the youth, have dared to resist him." From such speeches it is only a short step to plans for rebellion and conspiracy. In all probability the blame for this later and more bitter dissension must, as usually happens, be divided between the two factions. The party of Agrippina, emboldened by its good fortune and by the weakness of Tiberius, was, after the death of Drusus, conscious of its own supremacy. Its members had only a single aim; even before it was possible they wished to see Nero, the first-born son of Germanicus, in the position of Tiberius. They therefore took up again their struggles and intrigues against Tiberius, and attempted to incite Nero against the emperor. But this time Sejanus was blocking their pathway. The death of Drusus had even further increased the trust and affection which the emperor had for his assistant, and he was henceforth the only confidant and the only friend of the emperor; a war without quarter between him and Agrippina, her sons and the party of Germanicus, was inevitable. And Sejanus opened the action by attempting to exclude from the magistracy and from office all the friends of Agrippina and all the members of the opposing faction. At this time it was difficult to arrive at any of the more important offices without being recommended to the senate by the emperor, against whose choice the senate no longer dared to rebel; since the emperor was held responsible for the conduct of the government, it was only just that he should be allowed to select his more important collaborators. Sejanus was therefore able, by using his influence over Tiberius, to lay a thousand difficulties and obstacles in the way of even the legitimate ambitions of the most eminent men of the opposite faction. Nor were these the only weapons employed; others no less efficacious were called into play, and intrigues, calumnies, accusations, and trials were set on foot without scruple and with a ferocity the horror of which Tacitus has painted with indelible colors. Among these intrigues two matrimonial projects must be mentioned. In the year 25 Sejanus attempted a bold stroke; he repudiated his wife Apicata, and asked Tiberius for the hand of Livilla (Livia), the widow of Drusus. Sejanus had frequented the political aristocracy of the empire, and, despite his equestrian origin, was quick to adopt not only their ambitions and their manners, but also their ideas on marriage. He, too, considered it as simply a political instrument, a means of acquiring and consolidating power. He had therefore disrupted his first family in order to contract this marriage, which would have redoubled his power and his influence and have introduced him into the imperial household. But his bold stroke failed, because Tiberius refused; and he refused, Tacitus tells us, above all because he was afraid that this marriage would still further irritate Agrippina. The emperor is supposed to have told Sejanus that too many feminine quarrels were already disturbing and agitating the house of the Caesars, to the serious detriment of his nephew's sons. And what would happen, he asked, if this marriage should still further foment existing hatreds? Quid si intendatur certamen tali conjugio? The reply is significant, because it proves to us that Tiberius, who is accused of harboring a fierce hate against the sons of Germanicus and Agrippina, was still seeking, two years after the death of Drusus, to appease both factions, attempting not to irritate his adversaries and to preserve a reasonable equanimity in the midst of these animosities and these struggles.

In any case, Sejanus was refused, and this refusal was a slight success for the party of Agrippina, which, a year later, in 26, attempted on its own account an analogous move. Agrippina asked Tiberius for permission to remarry. If we are to believe Tacitus, Agrippina made this request on her own initiative, impelled by one of those numerous and more or less reasonable caprices which were continually shooting through her head. But are we to suppose that suddenly, after a long widowhood, Agrippina put forth so strange a proposal without any arrière-pensée whatever? Furthermore, if this proposal had been merely the momentary caprice of a whimsical woman, would it have been so seriously debated in the imperial household, and would the daughter of Agrippina have recounted the episode in her memoirs? It is more probable that this marriage, too, had a political aim. By giving a husband to Agrippina, they were also seeking to give a leader to the anti-Tiberian party. The sons of Germanicus were too young, and Agrippina was too violent and tactless, to be able alone to cope successfully with Sejanus, supported as he was by Tiberius, by Livia, and by Antonia. We can thus explain why Tiberius opposed and prevented the marriage: Agrippina, unassisted, had caused him sufficient trouble; it would have been entirely superfluous for him to sanction her taking to herself an official counselor in the guise of a husband.
This time Sejanus triumphed over the ill success of his rivals, and the struggle continued in this manner between the two parties, but with an increasing advantage to Sejanus. Beginning with the year 26, we see numerous indications that the party of Agrippina and Germanicus was no longer able to resist the blows and machinations of Sejanus, who detached from it, one after another, all the men of any importance. He either won them over to himself through his favors and his promises, or he frightened them with his threats; and those who resisted most tenaciously, he destroyed with his suits.
