Overview
Cleopatra of Macedonia (Greek: Κλεοπάτρα της Μακεδονίας; c. 355/354 BC – 308 BC), or Cleopatra of Epirus (Greek: Κλεοπάτρα της Ηπείρου) was an ancient Macedonian princess and later queen regent of Epirus. The daughter of Philip II of Macedon and Olympias of Epirus, she was the only full sibling of Alexander the Great. Her other siblings include half sisters Thessalonike and Cynane, and half-brother Philip III of Macedon.
Early life
Cleopatra grew up in the care of her mother in Pella. Olympias nurtured the familial bond in her children, ensuring they were raised in a "consistent political, moral, and cultural education and experience." Cleopatra, Olympias, Leonidas, and Alexander's friends were Alexander's closest relationships until Alexander was sent to Mieza at 13. In 338 BC, Cleopatra stayed in Pella with her father while her mother Olympias fled to exile in Epirus with her Molossian brother Alexander I of Epirus (Cleopatra's uncle), and Cleopatra's brother Alexander fled to Illyria. Soon Philip felt he had to ally himself to Alexander I by offering his daughter's hand in marriage. A large, international, extravagant wedding between Cleopatra and her uncle Alexander I was held in 336 BC. It was at the celebration of her nuptials, which took place on a magnificent scale at Aegae in Macedon, that Philip II was murdered.
Rule in Epirus
Immediately after her father's murder, Cleopatra and her husband-uncle Alexander went from Macedon back to Epirus. It is believed that the couple had two children, Neoptolemus II of Epirus and Cadmeia (named for her brother's defeat of the Theban revolt which began by attacking the garrison on the Cadmea).
Cleopatra held her brother Alexander's official favor, and likely kept in close contact with him while he was on his conquest to the east. Alexander considered her and Olympias as the inner circle of his basileia. In 332 BC Alexander had sent booty home for both his mother and sister, as well as his close friends. Cleopatra also used her influence to intercede on behalf of the tyrant Dionysius of Heraclea, and addressed the situation on Alexander's behalf.
