Austria and especially its capital Vienna are bustling with religions. Yet, the religious field is still largely uncharted. To engage more deeply with this great religious diversity, scholars collaborating in this research cluster aim at exploring the religious panorama in Austria both historically and contemporarily. Particular focus is thereby placed on non-mainstream religiosity, that is, the religious traditions/lifeworld beyond German-speaking Roman Catholicism. The affiliated scholars employ a vast panoply of historical, social-scientific, and comparative methods, all aligned through the prism of Religious Studies. The research results are disseminated through the peer reviewed book series Religion in Austria, published annually (starting from 2020) by Praesens.
