Thrace, with its heterogeneous population; proximity to the Greek civilisation; and the long-lasting dominance of the Persians, Macedonians, and Romans that has impacted culture, language, and political institutions of this historical landscape, is a unique testing ground for studying regionalism and identity in antiquity. This book explores these topics through the lens of coinage, numismatic iconography, and coin circulation. Including a series of case studies and theoretical chapters, this volume does not offer a conclusive solution to all of the questions that emerge. Yet the articles presented here, both in their entirety and individually, show the intricacy and manifoldness of the problem and outline prospects for further research.
