Cleopatra VII Philopator (in Greek, Κλεοπάτρα Φιλοπάτωρ; January 69 BC – 30 BC) was a Hellenistic ruler of Egypt, originally sharing power with her father Ptolemy XII an 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. In all, Cleopatra had four children, one by Caesar (Caesarion) and three by Antony (Cleopatra Selene II, Alexander Helios, and Ptolemy Philadelphus). Her unions with her brothers produced no children. It is possible that they were never consummated; in any case, they were not close. Her reign marks the end of the Hellenistic Era and the beginning of the Roman Era in the eastern Mediterranean. She was the last Pharaoh of Ancient Egypt (her son by Julius Caesar, Caesarion, ruled in name only before Augustus had him executed).
