This, however, was a crisis which was sooner or later inevitable. Agrippina had certainly made the mistake of attempting to treat Nero the emperor too much as she had treated Nero the child; but that the crisis should have been reached in this manner as the result of a love-affair, and that it should have provoked a misunderstanding between the mother and son that was soon to degenerate into hatred, was most unfortunate. Agrippina, though she enjoyed great prestige, had also many hidden enemies. Everybody knew that she represented in the government the old aristocratic, conservative, and economical tendency of the Claudii,—of Tiberius and of Drusus,—that she looked askance upon the development of luxurious habits, the relaxation of morals, and the increase of public and private expenditures. They understood that she exerted all her influence to prevent wastefulness, the malversation of public moneys, and in general all outlays for pleasures either in the state or the imperial family. Her virtues and her stand against Messalina had given her a great prestige, and the reverence which the emperor had shown for her had for a long time obliged her enemies to keep themselves hidden and to hold their peace. But this ceased to be the case after the incipient discord between her and Nero had allowed many to foresee the possibility of using Nero against her. In proportion as Nero became attached to Acte he drew away from his mother, and in proportion as he withdrew from his mother his capricious, fantastic, and rebellious temper was encouraged to show itself in its true light. The party of the new nobility, with its modern and oriental tendencies, had for ten years been held in check by the preponderating influence of Agrippina. But gradually, as the exotic and anti-Roman inclinations of the emperor declared themselves, this party again became bolder. The memories of the scandals of Caligula and Messalina were becoming effaced by time, the rather severe and economical government of Agrippina was showing signs of weakening, and all minds were beginning to entertain a vague desire for something new.

The two parties which in the times of Augustus had rent Rome asunder were now being realined in the imperial house and in the senate—the party of the old nobility, which had Agrippina at its head, and the party of the modernizing nobility, which was gathering about the emperor and trying to claim him as its own. Tacitus clearly tells us that the older and more respectable families of the Roman nobility were with Agrippina; and even if he had neglected to tell us so, we might easily have guessed it. For a moment the old, old struggle which had been the cause of so many tragedies in the upper classes of Rome seemed once more ready to break forth. But even though Agrippina was the soul of the party of the old nobility, the party needed a man whom it could oppose to Nero as a possible and better candidate for the imperial dignity.

Agrippina, like a true Roman matron of the old type, looked upon the family merely as an instrument of political power, and therefore subjected her personal affections to the public interest. She began to cast her eyes upon Britannicus, the son of Messalina, who was now becoming a young man and who seemed to be more serious-minded than Nero. It was even muttered that she thought of giving her own son's place to the son of Messalina, when suddenly, in 55, Britannicus died at a dinner at which Nero was present. Was he poisoned by Nero, as Tacitus says? Although there is no lack of obscurities and improbabilities in the account of Tacitus, this time the accusation, if it is not true, is at least much more probable than the other accusations of the same kind. It is certain that the report that Britannicus had been poisoned was soon current at Rome, and that it was believed; and the death of Britannicus was likewise a fatal blow to Agrippina and her party. Tacitus tells us that the death of Britannicus caused Agrippina great terror and unspeakable consternation, and it is not difficult to divine the reasons. Nero now remained the last and only survivor of the family of Augustus, and it was therefore no longer possible to bring any effective opposition to bear upon him by setting up some other member of the family who would be capable of governing. The new nobility, with its modern tendencies, now rapidly gained strength, and the influence of Agrippina declined proportionately.

As a result of the lofty qualities of genius and character with which she had been endowed, Agrippina had been able to hold the balance of power in the state as long as she had succeeded in keeping the emperor under her influence. This had been true in the cases of both Claudius and Nero. After Nero escaped from her influence, or, rather, after he had turned against her, her prestige and her power rapidly diminished, and her party lost greatly in size and in power. Although personally the emperor was youthful and weak, the dignity of his office made him more powerful than all the members of his family, however energetic and intelligent they might be. At this period, furthermore, Nero was supported by an entire party which was daily increasing in strength and in numbers, for, as always happens in eras of prosperity and peace, the temper of the time was tending toward a milder, gentler, more liberal government, and consequently one which would be less authoritative and severe.

Agrippina, however, was an energetic woman, not easily discouraged, and she continued the struggle. Consequently for two years longer, even in the midst of strife, intrigues, and suspicions, she preserved a considerable influence, and was able to check the progress of the government in its new direction. This was either because Nero, though no longer exactly obedient to his mother's will, was still too weak, too undecided, and too deeply involved in the ideas of his earlier education to attempt an open revolt against her, or it was because Seneca and Burrhus wisely sought to conciliate the ultra-conservative ideas of the mother with the newer tendencies of the son.

The definitive break with his mother and with her political ideas,—that is, with the ideas which had been professed by her ancestors,—came in 58, when Nero forgot Acte for Poppaea Sabina. The latter belonged to one of those great Roman families into which the new spirit and the new customs had most deeply penetrated. Rich, beautiful, avaricious of luxuries and pleasures, possessed of an unbridled personal ambition, she had attracted Nero to herself, and, in order to become empress, gave the uncertain youth the decisive impulse which was to transform the disciple of Agrippina and the grandson of Germanicus into the prodigal and dissolute emperor of history. She encouraged in him his desire to please the populace, and certainly never checked his love for Greece and the Orient, which resulted finally in his mania of everywhere imitating the example of Asia and of taking up again, though to be sure less wildly, the policies of Caligula. Tacitus tells us that she continually reproved Nero for his simple customs, his inelegant manners, and his rude tastes. She held up to him, both as an example and as a reproach, the elegance and luxury of her husband, who was indeed one of the most refined and pompous members of the degenerate Roman nobility. Poppaea, in short, gave herself up to the task of reshaping the education of Nero and of destroying the results of Agrippina's patient labor. Nor was this all. She even became, with her restricted intelligence, his adviser in politics. She persuaded him that the policy of authority and economy which his mother had desired was rendering him unpopular, and she suggested the idea of a policy of liberality toward the people which would win him the affection of the masses. After he had fallen in love with Poppaea Sabina, Nero, who up to that time had shown no considerable initiative in affairs of state, elaborated and proposed to the senate many revolutionary projects for favoring the populace. He finally proposed that they abolish all the vectigalia of the empire; that is, all indirect taxes, all tolls and duties of whatever sort. The measure would certainly have been most popular, and there was much discussion about it in the senate; but the conservatives showed that the finances of the empire would be ruined and persuaded Nero not to insist. Nero, however, wished to bring about some reform which would help the masses, and he gave orders in an edict that the rates of all the vectigalia be published; that at Rome the pretor, and in the provinces the propretor and proconsul, should summarily decide all suits against the tax-farmers and that the soldiers should be exempt from these same vectigalia.
