Alexander’s conquest of the Persian empire had far-reaching impact, in space and time. Much of the territory that he seized would remain under the control of Macedonian kings until the arrival of the Romans. But Macedonian power also brought with it Greeks and Greek culture. In this book, leading scholars in the field explore the creation of this Hellenistic world, its cultural, political and economic transformations, and how far these were a consequence of Alexander’s conquests. New kingdoms were established, new cities such as Alexandria and Antioch were founded, art and literature discovered fresh patrons. Egyptians and Iranians had to come to terms with Graeco-Macedonian rulers and settlers, while Greeks and Macedonians learned the ways of more ancient cultures. The essays presented here offer an exciting interdisciplinary approach to the study of this emerging Hellenistic world, its newness but also its oldness, both real and imagined.
