Processes of globalization have transformed the religious field, raising questions of identity for different religious traditions and their relations with the State, especially in European countries. Religious pluralism remains in most cases the most important characteristic of the current religious situation. This article reviews the origins of the phenomenon and the part it has played in the study of the sociology of religion, and examines the legal and political conditions that form the backdrop to pluralism. The author then considers some (...) consequences, taking as an example the `new religion' of the internet. Finally, the author considers the view of fundamental-ist movements as anti-modernist reactions to the identity crises experienced by religions such as Islam in the face of globalization. (shrink)
