husband Germanicus, she had nine children: Nero Julius Caesar, Drusus Julius Caesar, Tiberius Julius Caesar, a child of unknown name (normally referenced as Ignotus), Gaius the Elder, the Emperor Caligula (Gaius the Younger), the Empress Agrippina the Younger, Julia Drusilla, and Julia Livilla. Only six of her children came of age; Tiberius and Ignotus died as infants, and Gaius the Elder in his early childhood. Marriage Her husband's career in the military began in AD 6, with the Batonian War in Pannonia and Dalmatia. Throughout Germanicus' military career, Agrippina is known to have traveled with her husband and their children. Germanicus' career advanced steadily as he advanced in ranks following the cursus honorum until, in AD 12, he was made consul. The following year, he was given command over Gaul and the forces on the Rhine, totaling eight legions. On 18 May AD 14, her one-year-old son Gaius was sent by Augustus from Rome to join her in Gaul. She was pregnant at the time and, while Germanicus was collecting taxes across Gaul, she remained at an unspecified separate location, presumably for her safety. Augustus sent her a letter with her son's party, which read: Later that year, on 19 August, Augustus died while away in Campania. As a result, Tiberius was made princeps. While Germanicus was administering the oath of fealty to Tiberius, a mutiny began among the forces on the Rhine. During the mutiny, Agrippina brought out their sixth child, Gaius, and made preparations to take him away to a safer town nearby. He was in a full army outfit including the legionary hobnailed boots (caligae). These military-booties earned Gaius the nickname "Caligula" (lit. "little boots"), and garnered sympathy for Agrippina and the child among the soldiery. Tacitus attributes her actions as having quelled the mutiny (Tacitus, Annals 1.40–4). Once the mutiny was put to an end, Germanicus allowed the soldiers to deal with the ringleaders, which they did with brutal severity. He then led them against the Germanic tribes, perhaps in an effort to prevent future mutiny. Germanicus would remain in Gaul fighting against the Germanic tribes until AD 16, at which time he was recalled to Rome by Tiberius. His campaigns won him much renown among the Roman people, and he was awarded a triumph on 26 May AD 17. Widowhood In AD 18, Agrippina left for the eastern provinces with her family. Germanicus was sent
