7. Cleopatra Killed Her Younger Brother
The Ptolemaic Dynasty’s most famous ruler, Cleopatra VII, carried on the family’s tradition of incest by marrying her younger brother, Ptolemy XIII. Also carrying on another family tradition, this one of infighting, the siblings fell out, and Cleopatra was forced to flee Egypt to Syria. She soon returned with an army, and waged a civil war that tore the kingdom apart. The conflict seesawed between brother and sister/ husband and wife, until Julius Caesar arrived in Egypt in 48 BC, and sided with Cleopatra, who became his mistress.
Cleopatra’s brother refused to accept the Roman dictator’s decision, however, and sought to contest the issue militarily. It did not work out well for him, and in the Battle of the Nile in December of 48 BC, Ptolemy XIII’s army was routed by Caesar. Cleopatra’s brother/ husband drowned in the aftermath, either accidentally or at the hands of his sister’s agents. Cleopatra then married another brother, Ptolemy XIV, while continuing her affair with Caesar. She bore the Roman dictator a son, Caesarion, the future Ptolemy XV – the dynasty’s last nominal ruler.
