The second volume of biographies from the series "All the Monarchs of the World" is dedicated to the sovereigns of antiquity: Ancient Greece and Ancient Rome, as well as the emperors of Byzantium. We hope that due to the completeness of the material, our publication will be a good guide for all history lovers. For the first time, under one cover, detailed biographies of all Greek, Macedonian and Hellenistic kings, as well as Roman and Byzantine emperors, who ruled for twenty-seven centuries from the time of the Dorian conquest of Greece until the capture of Constantinople by the Turks, are collected.
