Year of the Four Emperors
Gaius Julius Caesar (20 BC – 21 February AD 4), most commonly known as Gaius Caesar or Caius Caesar, was the oldest son of Marcus Vipsanius Agrippa and Julia the Elder. He was born between 14 August and 13 September 20 BC or according to other sources in 23 September 20 BC. Originally named Gaius Vipsanius Agrippa, when he was adopted by his maternal grandfather the Roman Emperor, Augustus Caesar, of the Julian gens, his name was accordingly changed to Gaius Julius Caesar.
Early life 
Gaius was adopted along with his brother Lucius Caesar in 17 BC by their maternal grandfather, the Roman Emperor Augustus, who named the two boys his heirs. In 6 BC the Roman plebs agitated for Gaius to be created consul, despite the fact that he was only 14 and had not yet assumed the toga virilis. As a compromise, it was agreed that he should have the right to sit in the Senate House, and he was made consul designatus with the intention that he should assume the consulship in his twentieth year. Gaius was at this point created "Youth Leader" ("princeps iuventutis"), an honorific that made him one of the symbolic heads of the equestrian order. Lucius, three years his junior, was granted the same honours after the appropriate interval had elapsed. Temples and statues were erected in their honour (as in the case of the Maison Carrée in Nîmes). In 1 BC he was made army commander in the East and made a peace treaty with Phraates V on an island in the river Euphrates. In 1 AD, he was made Consul with Lucius Aemilius Paullus as his colleague.
Lucius died at Massalia in Gaul on 21 or 22 February AD 2 and his cenotaph is situated there. Gaius died two years later in Lycia at the age of 24, after being wounded during a campaign in Artagira, Armenia.
The death of both Gaius and Lucius, the Emperor's two most favored heirs, compelled Augustus to adopt his stepson, Tiberius, and his sole remaining grandson, Postumus Agrippa as his new respective heirs.
It has been suggested by Tacitus that there may be been foul play involved in the death of Gaius and that Gaius' step mother Livia may have had a hand in his death. Livia's presumed motive may have been to orchestrate the accession of her own son Tiberius as heir to Augustus.
