Livia (left), Drusus (center), and Agrippina the Elder (right). Her marriage to Germanicus had served to unite the imperial family. Agrippina may have suspected Tiberius' involvement in the death of her husband and, with Germanicus dead, she no longer had any familial ties to the emperor. Historian
Richard Alston says it is likely that either Tiberius or Livia were behind the exile of Agrippina's sister Julia the Younger and the death of Postumus. He notes the death of Agrippina's mother, who starved herself to death amidst her exile in AD 14, linking her death to Tiberius' disdain for her. Agrippina was vocal about her feelings claiming that Germanicus was murdered to promote Drusus the Younger as Tiberius' heir, and worried that the birth of the Younger Drusus' twin sons would displace her own sons in the line of succession. At about this time, Tiberius'
Praetorian Prefect Sejanus was becoming powerful in Rome and began feuding with Drusus the Younger. While the exact causes of the feud are unknown, it ended when the Younger Drusus died of seemingly natural causes on 14 September AD 23. After the death of Tiberius' son, Agrippina wanted to advance the careers of her sons, who were all potential heirs for Tiberius. It has been suggested that to achieve this, Agrippina commissioned the
Great Cameo of France and presented it to Tiberius as a personalized gift that positioned the family of Germanicus around the emperor. The work was designed to convince Tiberius to choose her children as his heirs. Ultimately, the death of Tiberius' son elevated her own children to the position of heirs. Her sons were the logical choice, because they were the sons of Germanicus and Tiberius' grandsons were too young. Nero was becoming popular in the
Senate due in part, Tacitus says, to his resemblance with his father. The rise of her children was threatening to Sejanus' position. Resultantly, Sejanus began spreading rumors about Agrippina in the imperial court. The coming years were marked with increasing hostility between Sejanus and Agrippina and her sons. This effectively caused factions to rise in the aristocracy between her family and Sejanus.
Political rivalry of
Caligula with Agrippina on the obverse, minted circa AD 37. On
New Year's Day, AD 24, Sejanus had the
priests and magistrates add prayers for the health of Nero and Drusus in addition to those normally offered to the emperor on that day. Tiberius was not happy with this and he voiced his displeasure in the Senate. In addition, he questioned the priests of the
Palatine. Some of the priests who offered the prayers were relatives of Agrippina and Germanicus. This made Tiberius suspicious of her and marked a change in his attitude toward her and her older sons, but not Caligula. In AD 25, Sejanus requested Livilla's hand in marriage. Livilla was a niece of the emperor, which would have made him a member of the imperial family. While this did make his ambitions clear, his request was denied. The loss may have been huge for Sejanus had the dissensions in the imperial household not been deteriorating. Relations were so bad that Agrippina refused to eat at Tiberius' dinner parties for fear of being poisoned. She also asked Tiberius if she could be allowed to remarry, which he also refused.
Downfall With Tiberius away from Rome, the city would see a rise of politically motivated trials on the part of Sejanus and his supporters against Agrippina and her associates. Many of her friends and associates were subsequently accused of
maiestas ("treason") by the growing number of accusers. It was also common to see charges of sexual misconduct and corruption. In AD 27, Agrippina found herself placed under house arrest in her suburban villa outside
Herculaneum. In AD 28, the Senate voted that altars to
Clementia (mercy) and
Amicitia (friendship) be raised. At that time,
Clementia was considered a virtue of the ruling class, for only the powerful could give clemency. The altar of
Amicitia was flanked by statues of Sejanus and Tiberius. By this time, his association with Tiberius was such that there were those in Roman society who erected statues in his honor and gave prayers and sacrifices to Sejanus. Sejanus' birthday was honored as if he were a member of the imperial family. According to Richard Alston, "Sejanus' association with Tiberius must have at least indicated to the people that he would be further elevated." Sejanus did not begin his final attack on Agrippina until after the death of Livia in AD 29. Tacitus reports a letter being sent to the Senate from Tiberius denouncing Agrippina for her arrogance and prideful attitude, and
Nero for engaging in shameful sexual activities. The Senate would not begin these highly unpopular prosecutions against her or her son until it received clear instructions from Tiberius to do so. Despite public outcry, Agrippina and Nero were declared public enemies (
hostes) following a repeat of the accusations by the emperor. They were both exiled; Nero to
Pontia where he was killed or encouraged to commit suicide in AD 31, and Agrippina to the island of
Pandateria (the same place her daughter was exiled to).
Suetonius says that while on the island of Pandateria, she lost an eye when she was beaten by a centurion. She would remain on the island until her death in AD 33. Accounts of her death vary. She is said to have died from starvation, but it is not certain whether or not it was self-imposed. Tacitus says food was withheld from her in an effort to make her death seem like a suicide. ==Post mortem==
