The toleration of religious minorities is changing in the Netherlands. In this paper we analyze three recent developments in Dutch society that are important for understanding the way the Dutch regime of religious tolerance is adjusting to 21st century circumstances. The first one concerns the growing homogenization of Dutch society and the emergence of a secular and liberal majority. The second is the dominance in policy and public debate of a "Protestant"conception of what religion amounts to. The third development is the fragmentation of religion and its simultaneous combination into new networks and groups made possible by new information and communication technologies. These developments pose challenges to constitutional rights and principles. There are no simple solutions to these challenges, but the Dutch tradition of consociationalism, as a liberal tradition in its own right, may provide some valuable perspectives.
