Due to the crowded nature of Rome at the time, Octavius was taken to his father's home village at Velletri to be raised.
Octavius only mentions his father's equestrian family briefly in his memoirs.
Because of this, Octavius was raised by his grandmother, Julia, the sister of Julius Caesar.
Augustus dramatically enlarged the Empire, annexing Egypt, Dalmatia, Pannonia, Noricum, and Raetia; expanding possessions in Africa; expanding into Germania; and completing the conquest of Hispania.
Beyond the frontiers, he secured the Empire with a buffer region of client states and made peace with the Parthian Empire through diplomacy.
He was born Gaius Octavius into an old and wealthy equestrian branch of the plebeian gens Octavia.
His maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesar's will as his adopted son and heir, then known as Octavianus (Anglicized as Octavian).
However, though some of his contemporaries did, Historians usually refer to the new Caesar as Octavian during the time between his adoption and his assumption of the name Augustus in 27 BC in order to avoid confusing the dead dictator with his heir.
