Answer
Caesarion, the son of Julius Caesar, was born to Cleopatra VII, the last pharaoh of Egypt. Their relationship was a political alliance, with Caesar seeking to secure Egypt's loyalty and Cleopatra hoping to gain Roman support for her rule. Despite Caesar's assassination, Cleopatra continued to present Caesarion as his heir, but he was ultimately defeated and killed by Octavian, Caesar's adopted son, in the Battle of Actium.
