Cleopatra VII (69 BC ? 30 BC) was a Hellenistic ruler of Egypt, originally sharing power with her father Ptolemy XII and later with her brothers/husbands Ptolemy XIII and Ptolemy XIV; eventually gaining sole rule of Egypt. As Pharaoh, she consummated a liaison with Gaius Julius Caesar that solidified her grip on the throne, and, after Caesar's assassination, aligned with Mark Antony, with whom she produced twins.
