Who was Cleopatra successor?

Cleopatra's successor was Octavian, who, as sole ruler of the Roman empire, turned Egypt into an imperial province. This meant that the province of Egypt was under direct control of the "first citizen". Because of Egypt's wealth and geographical position, it had the potential to be a place where revolution could form against Rome. To avoid this, Augustus decreed that it would always be governed by someone of equestrian rank and no one holding the office of praetor or above could enter the province without expressed permission of the emperor.
