After Alexander the Great's death, Egypt was administered by Ptolemy, one of his friends and generals. In 305 B.C., Ptolemy crowned himself king, establishing one of the most important and flourishing Hellenistic monarchies. Ptolemaic rule lasted for 275 years, until 30 B.C. The culture was a complex mixture of Egyptian and Greek traditions, best represented by the famous city of Alexandria. All the male rulers of the dynasty took the name Ptolemy, while queens regnant were all called Cleopatra, Arsinoe or Berenice. The most famous member of the line was the last queen, Cleopatra VII, known for her role in the Roman political battles between Julius Caesar and Pompey, and later between Octavian and Mark Antony. Her suicide at the conquest by Rome marked the end of Ptolemaic rule in Egypt.
