So it was Octavian versus Antony and Cleopatra (and Caesarion) for control of Rome. After Caesar's assassination on 15 March 44 BC, Cleopatra and Caesarion returned to Egypt. Caesarion was said to have inherited Caesar's looks and manner, but Caesar apparently did not officially acknowledge him. He also dubbed Caesarion Caesar’s true heir — in direct defiance of Octavian’s claims — and nominally distributed kingdoms to his three kids with Cleopatra. Caesarion was about three years old when Caesar died.
However, he was murdered by Octavian’s orders just 11 days later.
Octavian lured the young king to Alexandria and ordered the death of his step-brother, Caesarion and so it happened. Caesarion, from the "Unravel the Mystery" Cleopatra exhibit ( CC0 1.0 ) Caesarion was about three years old when Caesar died. Caesarion probably held the position as ruler after the death of his mother on August 12, 30 BC. With his death, Octavian lost the only competition he had to the throne of Rome. Octavian chooses authoritarianism over democracy while Caesarion (‘Little Caesar’) is already dead, buried and not particularly often mentioned in historical records – simply – forgotten. Cleopatra and Caesarion later followed Caesar back to Rome, but, after his assassination in 44 bce, they returned hurriedly to Egypt, and she tried for a while to play a neutral role in the struggles between the Roman generals and their factions.… Caesarion was about three years old when Caesar died.
