Berenice IV took her father's throne, had one husband strangled within days, and was executed when Rome restored her father for 10,000 talents

In 58 BC Rome annexed Cyprus, and its king, Ptolemy XII's brother, killed himself. The Alexandrians, angry, drove Ptolemy XII out, and he went to Rome. They made his eldest legitimate daughter, Berenice IV, queen. She needed a husband of royal blood. One Seleucid candidate died during the talks. Aulus Gabinius, the Roman governor of Syria, forbade a second. The third, Seleucus, claimed descent from the Syrian kings and was nicknamed Kybiosaktes, "Salt-fish-monger." Strabo writes that she had him strangled within a few days because she could not bear his coarseness. She then married Archelaus, who claimed to be a son of Mithridates of Pontus and was priest of Comana. He reigned with her in the winter of 56 to 55 BC. In Rome, Ptolemy XII had promised Gabinius 10,000 talents to restore him. In spring 55 BC Gabinius marched into Egypt. Archelaus was killed. Ptolemy XII had Berenice executed for usurping his throne. Berenice IV was buried in Alexandria; the site is not known.
