It is almost exactly 2500 years ago that the decisive clashes of the Persian Wars at Thermopylae, Salamis and Plataia took place. These battles were attributed world-historical significance in antiquity and, even more so, in the centuries that followed. Yet, the details of what happened, as well as their military-political and cultural impact and detailed evaluation, have been the subject of much controversial research, not least because of the difficult nature of the sources. The present volume is the outcome of a conference held in Budapest which celebrated the anniversary of Xerxes' expedition against Hellas by discussing old and new questions related to the war and the history of its reception. It was jointly organised by the editors of the volume and attracted speakers from around the globe. The volume brings together scholars of all branches of classical studies and related disciplines and is organised in two sections: (i) Graeco-Persian Wars, Diplomacy and Acculturation, (ii) Commemorating and remembering the war from antiquity to the present. 19 contributors from 10 different countries provide a good overview of ongoing studies in the field.
