The article sketches the overall layout of the thematic issue of the ‘Journal of Religion and Transformation in Contemporary Societies (JRAT)’ on Interreligious Dialogue (IRD) in context. It argues that an analysis of interreligious dialogue activities in their socio-cultural contexts helps to counterbalance the long-standing individualistic bias of IRD-research. First, it presents a systematic description of the present state of the art that distinguishes two strands of IRD-research. Second, it argues for a European comparison, based upon most recent findings from the ‘SMRE – Swiss Metadatabase of Religious Affiliation in Europe’. The article is based on the research “Intercultural and interreligious dialogue to promote the culture of peace in unaccompanied foreign youth and minors (MENA) in Barcelona and Melilla” (RTI2018-095259-B-I00 / MCIU / AEI / FEDER, EU) and closes with references to the structure of the present volume of JRaT to facilitate such a comparison.
