Book excerpt: The seemingly vitalizing impact of religiosity on civil society is a research topic that has been extensively looked into, not only in the USA, but increasingly also in a European context. What is missing is an evaluation of the role of institutionalized religious communities, and of circumstances that facilitate or impede their status as civil society organisations. This anthology in two volumes aims at closing this gap by providing case studies regarding political, legal and historical aspects in various European countries. Vol. I provides an introduction and looks at cases in Greece, Italy, the Netherlands, Sweden, and Bosnia and Herzegovina, as well as chapters on legal issues and data, and comprehensive bibliography.
