Abstract

Tacitus traces a series of conflicts between Agrippina the Elder and her father-in-law Tiberius. After the death of her husband Germanicus in Syria, Agrippina returned to Rome with their children. Germanicus' lingering popularity with the armies and people meant that his widow Agrippina and their children enjoyed a level of popular support as well—one that eventually became a threat in Tiberius' mind. Agrippina, moreover, refused to embrace the modest, retiring role that her father-in-law expected of her. Tiberius was, moreover, ‘never gentle toward the house of Germanicus’ and his concerns were augmented by the machinations of Sejanus, who reported that the people were dividing themselves into factions, some even calling themselves members of the partes Agrippinae. The combination of Agrippina's high birth—the only still-living grandchild of Augustus—and her status as widowed daughter-in-law of the emperor, therefore mother of the emperor's probable heir, along with her persistent independence and sometimes unfeminine strength of character made her seem an intolerable political threat. This paper examines the culmination of these conflicts, when Agrippina is subjected to criminal prosecution and penalty in a.d. 27 and 29 at the instigation of Sejanus, with the overt approval of Tiberius. Of primary concern is the timing and the order of the charges brought against Agrippina.
