All the male rulers of the dynasty took the name Ptolemy. Ptolemaic queens, some of whom were the sisters of their husbands, were usually called Cleopatra, Arsinoe or Berenice. The most famous, was the last queen, Cleopatra VII. She was involved in the Roman political battles between Julius Caesar and Pompey, and later between Octavian and Mark Antony. Her death marked the end of Ptolemaic rule in Egypt.
