Becoming a Divine Queen
From the beginning of her reign, Cleopatra put religion to political use. When Ptolemy XII Auletes died, his will named his daughter Cleopatra joint ruler with her 10-year-old brother Ptolemy XIII. In an attempt to establish herself as Egypt's sole monarch, Cleopatra immediately courted the native priesthood and population. She toured Upper Egypt's great temples, led an elaborate Nile procession with the new Buchis bull and delivered ritual prayers in its honor.
The strategy appeared to pay off. In July 51 B.C., Wennefer, one of Egypt’s chief priests of Isis, erected an inscription that referred to the young ruler as “the female king Cleopatra Father-Loving Goddess,” omitting her younger brother altogether.
Support from Egypt's priesthood alone, however, couldn’t save Cleopatra when in 49 B.C., Ptolemy XIII's advisers forced her into exile in Syria. There, she raised an army of mercenaries to confront her brother's forces at the fortress city of Pelusium.
Before the battle could begin, though, another opportunity presented itself: Julius Caesar had arrived in Alexandria. Cleopatra secretly arranged to be smuggled into the royal palace to plead her case for support. Whether concealed in a bedding sack, as Plutarch describes, or in the rolled-up rug of later legend, the gamble paid off.
Caesar defeated the forces of Ptolemy XIII during the Alexandrian War, and Ptolemy XIII is believed to have drowned in the Nile River. Caesar then restored Cleopatra to the throne alongside her other brother, Ptolemy XIV. As the Roman historian Cassius Dio observed, however, the joint-rule was “a mere pretence which she accepted, whereas in truth she ruled alone and spent her time in Caesar's company."
