Berenice IV was the oldest daughter of Auletes (Ptolemy XII Neos Dionysos) and ruled for three years during his exile. At the beginning of his exile, she co-ruled with her mother Cleopatra V Tryphaena until the mother's death about a year later. Berenice ruled as sole regent and was expected to marry.
The one selected was Seleucus Kybiosaktes. After a few days, she had her husband strangled. The second man she chose was Archelaus. Her father finally paid out enough money and was brought back to Egypt. Archelaus' army was defeated and Pompey suggested that Auletes be returned to the throne. One of his first acts was to have his daughter, Berenice, executed.
