Cleopatra was the last pharaoh; after her death Egypt became a Roman province. Because Caesarion was Julius Caesar's son and might pose a threat to Octavian's power, Octavian had the boy strangled by his tutor. Cleopatra's other children were sent to Rome to be raised by Octavia. Cleopatra Selene married King Juba II of Mauretania and had two children, Ptolemy and Drusilla. No one knows what happened to Alexander Helios and Ptolemy Philadelphus.
