The future emperor Augustus was born Gaius Octavius on September 23 63 BC. He was the great nephew of Julius Caesar.It is because of this close tie to Caesar that Octavian had many political connexions in Rome. Caesar had favoured the young Octavius from a very early age. In 48 BC ,when he was 15 years old, Caesar enrolled Octavius in the priestly college of the Pontifaces and into the hereditary Patrician class in Rome. Octavius also joined Caesar on a military campaign in Spain on 46 BC. Later, Octavius was sent by Caesar to Apollonia ,in Greece, to finish his education. During his time in Apollonia, Octavius trained with Roman Legions who were stationed there at the time. It was during his stay here that he had learned about Caesar's assassination and that he was Caesar's adopted heir.
