Book excerpt: The Greek and Jewish diasporas are the most significant diasporas of Western civilisation. "Homelands and Diasporas" is the first book to explore the similarities and differences between these two experiences. In the process it sheds fascinating light on their fundamental importance for both Greek and Jewish societies. The authors examine Greek and Jewish diasporas throughout history, from classical and Biblical times to the present, and all over the world - in Greece, the Balkans, Turkey, Russia, the Near and Middle East, Spain and the US. They analyse the very nature of diaspora, examining both the Greek concept of noble expansion and the Jewish idea of enforced exile, and analyse community structures as well as social and religious networks, combining Scriptural analysis with cultural and political history. Diaspora is a difficult and emotive concept but "Homelands and Diasporas" offers a balanced and perceptive guide to the connected histories of these two peoples away from their homelands.
