Answer
Pharaoh was the title held by Caesarion, the son of Julius Caesar and Cleopatra VII. As the last pharaoh of the Ptolemaic dynasty, Caesarion ruled Egypt alongside his mother until their defeat by Octavian in the Battle of Actium. After his mother's suicide, Caesarion was captured and executed by Octavian, marking the end of the Ptolemaic dynasty and the beginning of Roman rule in Egypt.
