Agrippina the Younger (Latin: Julia Agrippina; 6 November AD 15 – 23 March AD 59), also referred to as Agrippina Minor ("smaller", often used to mean "younger"), was a Roman empress and one of the more prominent women in the Julio-Claudian dynasty. Her father was Germanicus, a popular general and one-time heir apparent to the Roman Empire under Tiberius; and her mother was Agrippina the Elder, a granddaughter of the first Roman emperor Augustus. She was also the younger sister of Caligula, as well as the niece and fourth wife of Claudius.
Both ancient and modern sources describe Agrippina's personality as ruthless, ambitious, violent, and domineering. Physically she was a beautiful and reputable woman; according to Pliny the Elder, she had a double canine in her upper right jaw, a sign of good fortune. Many ancient historians accuse Agrippina of poisoning her husband Claudius, though accounts vary. She briefly served as the de facto ruler of Rome during the reign of her son, emperor Nero. In AD 59 Agrippina was executed on the orders of Nero.
