Agrippina The Younger - Reign of Caligula

Reign of Caligula

Tiberius died on March 16, 37 and Agrippina's only surviving brother, Caligula, became the new emperor. Being the emperor's sister gave Agrippina some influence.

Agrippina and her younger sisters Julia Drusilla and Julia Livilla received various honors from their brother, which included but were not limited to:

• They were given the rights of the Vestal Virgins like the freedom to view public games from the upper seats in the stadium.
• Coins were issued depicting images of Caligula and his sisters. Roman coins like these were never issued beforehand. The coins depicted Caligula on one side and his sisters on the opposite.
• Caligula added his sister's names in to motions. In loyalty oaths, it was, "I will not value my life or that of my children less highly than I do the safety of the Emperor and his sisters," or, if in consular motions: "Good fortune attend to the Emperor and his sisters."

Around the time that Tiberius died, Agrippina had become pregnant. Domitius had acknowledged the paternity of the child. In the early morning hours in Antium of December 15, 37, Agrippina gave birth to a son. Agrippina and Domitius named their son Lucius Domitius Ahenobarbus, after the Domitius' recently deceased father. This child would grow up to become the Emperor Nero. Nero was Agrippina's only natural child. Suetonius states that Domitius was congratulated by friends on the birth of his son, whereupon he replied "I don't think anything produced by me and Agrippina could possibly be good for the state or the people".

Caligula and his sisters were accused of having incestuous relationships. On June 10, 38, Drusilla died, possibly of a fever, rampant in Rome at the time. He was particularly fond of Drusilla, claiming to treat her as he would his own wife, even though Drusilla had a husband. Following her death, Caligula's relationship with Agrippina and Livilla changed, showing no special love or respect toward them after Drusilla's death. After this point, he was said to have gone insane.

In 39, Agrippina and Livilla, with their maternal cousin, Drusilla's widower Marcus Aemilius Lepidus, were involved in a failed plot to murder Caligula, a plot known as the Plot of the Three Daggers, which was to make Lepidus the new emperor. Lepidus, Agrippina and Livilla were accused of being lovers. Not much is known concerning this plot and the reasons behind it. At the trial of Lepidus, Caligula felt no compunction about denouncing them as adulteresses, producing handwritten letters discussing how they were going to kill him.
