Elder sister of Cleopatra VII, briefly ruled.
Compare Berenice IV of Egypt with another historical figure:
Berenice IV became co-ruler of Ptolemaic Egypt alongside her mother Cleopatra V Tryphaena after her father Ptolemy XII Auletes was exiled to Rome. She ruled as the senior monarch after her mother's death in 57 BC.
Berenice IV married Seleucus Kybiosactes, a claimant to the Seleucid throne, to strengthen her position. The marriage was brief and unhappy; she reportedly had him killed soon after.
Berenice IV married Archelaus, a priest-king of Comana in Cappadocia, to secure a capable co-ruler. Archelaus claimed descent from Mithridates VI of Pontus, adding legitimacy to her reign.
After Ptolemy XII Auletes returned to Egypt with Roman military support from Aulus Gabinius, he captured Alexandria and ordered the execution of Berenice IV. Her death ended her independent rule and restored her father to the throne.
