Why did the son of Julius Caesar and Cleopatra killed?

Answer 1

Julius Caesar had no legitimate son. His only son was Octavian who he adopted. Cleopatra of Egypt claimed that her illegitimate son was fathered by Caesar, but there are questions about this. At any rate, any child of Cleopatra and Caesar would have been considered illegitimate under Roman law and not entitled to inherit. So yes, Caesar's son, Octavian, did hunt down and kill those who were responsible for killing Caesar.

Answer 2

No. Julius Caesar had no legitimate son. He was stabbed by the group of senators that pressed around him and it is not known which one actually dealt the lethal wound. (It is said that of all Caesar's wounds, only one was fatal).

Answer 3

Caesarion, the son of Cleopatra and the supposed son of Julius Caesar had to be killed because as long as he lived he would be a threat to Octavian. A minor threat was that some people believed that Caesarion was Caesar's natural son. However under Roman law, an adopted son, such as Octavian, had the same rights as a natural son. Octavian's legitimacy as Caesar's heir was not endangered on this point, especially since Caesar never recognized Caesarion nor did he mention him in his will. But a second, more real threat, was one of revolution. Caesarion had been co-ruler with his mother and was actually a king of Egypt. There was always the possibility of political unrest in Alexandria, and it would not take much for the Alexandrians to try to establish Caesarion back on the throne. Also, Marc Antony had recognized Caesarion as a Roman, which made him a double threat to Octavian and possibly to Rome.

Answer 4

All we can factually say is that Julius Caesar was killed by members of the senate. In spite of all his stab wounds, only one wound was reported to have been fatal and there's no way of knowing who gave it.
