Over the last decade, concepts of diaspora and locality have gained complex new meanings in political discourse as well as in social and cultural studies. Diaspora, in particular, has acquired new meanings related to notions such as global deterritorialization, transnational migration and cultural hybridity. The authors discuss the key concepts and theory, focus on the meaning of religion both as a factor in forming diasporic social organisations, as well as shaping and maintaining diasporic identities, and the appropriation of space and place in history. It includes up to date research of the Caribbean, Irish, Armenian, African and Greek diasporas.
