Nero Julius Caesar Germanicus (c. AD 6–31) was the adopted son and heir of Tiberius, alongside his brother Drusus. Born into the prominent Julio-Claudian dynasty, Nero was the son of Tiberius' general and heir, Germanicus. After the deaths of his father and of Tiberius' son, Drusus the Younger, Nero and his brother Drusus were adopted together by Tiberius in September AD 23. As a result of being heirs of the emperor, he and his brother enjoyed accelerated political careers. Sejanus had become powerful in Rome and is believed by ancient writers such as Suetonius and Tacitus to have been responsible for the downfall of Drusus the Younger. As Sejanus' power grew, other members of the imperial family began to fall as well. In AD 29, Tiberius wrote a letter to the Senate attacking Nero and his mother, and the Senate had them both exiled. Two years later, he died in exile on the island of Ponza. His brother Drusus also died in exile in AD 33. Their deaths allowed for the adoption and ascension of their brother, Gaius Caligula, following the death of Tiberius in AD 37.
