Cleopatra Selene II

Cleopatra Selene II (Greek: Κλεοπάτρα Σελήνη; summer 40 BC – c. 5 BC; the numeration is modern) was a Ptolemaic princess, nominal Queen of Cyrenaica (34 BC – 30 BC) and Queen of Mauretania (25 BC – 5 BC) as co-ruler alongside her husband Juba II. She was an important royal woman in the early Augustan age.

Cleopatra Selene was the only daughter of Greek Ptolemaic Queen Cleopatra VII of Egypt and Roman Triumvir Mark Antony. In the Donations of Antioch and of Alexandria, she was made queen of Cyrenaica and Libya. After Antony and Cleopatra's defeat at Actium and their suicides in Egypt in 30 BC, Selene and her brothers were brought to Rome and placed in the household of Octavian's sister, Octavia the Younger, a former wife of her father.

Selene married Juba II of Mauretania. She had great influence in Mauretania's government decisions, especially regarding trade and construction projects. During their reign, the country became extremely wealthy. The couple had a son and successor, Ptolemy of Mauretania. Through their granddaughter Drusilla, the Ptolemaic line intermarried into Roman nobility for many generations.
