Julia Agrippina the Younger was born in the year 15. She was the daughter of Germanicus and Agrippina the Elder, and she was the sister of Caligula. She married Gnaeus Domitius Ahenobarbus and had a son, who would later be the emperor Nero. Then she married Gaius Sallustius Crispus Passienus in 41. In 49, she married Claudius and persuaded him to adopt Nero as his heir. Following his murder (debated to be her doing or not), she became regent to Nero's emperorship. However, he sent her into exile and killed her in 59 AD.
