Ptolemy XV (Ptolemy Caesarion), 47–30 B.C., son of Cleopatra and (almost certainly) Julius Caesar. He became joint ruler with his mother, but played no role in the great and tragic events that brought Egypt and Cleopatra to their doom. Fearing that he might gain popular support, Octavian (later Emperor Augustus) had him put to death.
