This text was originally composed for the 2023 annual conference on "Religious Ambivalences" of the second funding phase (2022–2026) of the Centre for Advanced Studies 'Religion and Urbanity,' funded by the German Research Foundation. (Further information: https://urbrel.hypotheses.org/4965) Subsequent to this, the text has been the subject of repeated discussion and expansion. Prior to submission to a journal, the contents and theses are made available for discussion here (pre-proofread, pre-peer reviewed). The group's objective is to examine the reciprocal influence of religion and urbanity in order to ascertain whether long-term processes of differentiation, embedding and disembedding can be identified. The introduction of the concept of a core ambivalence of urbanity is intended to direct attention towards a fundamental dimension of urban life. It is not asserted that this concept exhausts the notion of urbanity or the conflicts encountered in urban lifeworlds.

Research results are published continuously via the open access platform and journal "Religion and Urbanity Online" (de Gruyter): https://doi.org/10.1515/urbrel
