The "Annals" of Tacitus is a history of the Julio-Claudian dynasty beginning with the death of Augustus. In it, he portrays women as having a profound influence on politics. The women of the imperial family in particular are depicted by Tacitus as having a notable prominence in the public sphere as well as possessing a ferocity and ambition with which they pursue it. Tacitus presents them as living longer than the imperial men and thus being more wise as they advance in age. Among the most broad of his portrayals is that of Agrippina. He emphasizes their role in connecting genetically back to Augustus, a significant factor in the marriages of the emperors and princes of the dynasty. The Annals repeatedly has Agrippina competing for influence with Tiberius simply because she is related to Augustus biologically.
