Germanicus
Germanicus (24 May 15 BC – 10 October AD 19) was a member of the Julio-Claudian dynasty and a prominent general of the early Roman Empire. He was born in Rome, Italia, to Nero Claudius Drusus and his wife Antonia Minor. His original name at birth was either Nero Claudius Drusus after his father, or Tiberius Claudius Nero after his uncle, the second Roman emperor Tiberius. The agnomen Germanicus was added to his full name in 9 BC when it was posthumously awarded to his father in honour of his victories in Germania. By AD 4 he was adopted as Tiberius' son and heir. As a result, Germanicus was adopted out of the Claudii and into the Julii. In accordance with Roman naming conventions, he adopted the name Germanicus Julius Caesar.
In addition to Germanicus' relation to Tiberius, he was also a close relative to the other four Julio-Claudian emperors. On his mother's side Germanicus was a great-nephew of Augustus, the first emperor of Rome. By marrying his maternal second cousin, Agrippina the Elder, he became Augustus' grandson-in-law. Gaius (also known as Caligula), the emperor who succeeded Tiberius, was the son of Germanicus. After Caligula the emperorship passed to Claudius, Germanicus' younger brother. Nero, the last emperor of Augustus' dynasty, was a grandson of Germanicus on the side of his mother, Agrippina the Younger.
