Interactive Histories, Co-Produced Communities: Judaism, Christianity, Islam

Our goal is to provide the foundations of a new history of Judaism, Christianity, and Islam as co-produced communities, a history that makes clear the many different ideas and ideals that each of these communities has formed, and continues to form, by interacting with or imagining the others.

Conference: Co-produced Rituals between Judaism, Christianity, and Islam: Uncovering a Common Late Antique and Early Medieval Religious Culture

APR 2–3, 2025 Bern, Switzerland

Organized by Caroline Bridel and Maureen Attali

Historical and anthropological studies often point out what they consider to be ritual similarities between Jews, Christians, and Muslims. The study of both literary and material data suggests that many of those rituals originated from or developed upon practices performed by all inhabitants of the Roman and/or Sassanian empires. This workshop proposes to investigate the formation processes and early development and contexts of so-called Abrahamic rituals through the notion of religious co-production.
