Caesarion

Born in 47 BC, Ptolemy XV Caesar was named for his father and raised in the shadow of empires colliding. Cleopatra made him co-ruler at three, after Caesar's assassination left them both exposed. For fourteen years he reigned beside her as Egypt tried to navigate Rome's civil wars. When his mother died by suicide in August 30 BC, Alexandria had already fallen to Octavian. The boy pharaoh went into hiding, but Octavian tracked him down within days — one rival too many to let live. His execution ended the Ptolemaic dynasty and closed three millennia of Egyptian kingship.
