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.

Sometimes this history can be illuminated in surprising ways. This case study considers how a tweet can shed light on the history and continuing relevance of the relations between these two religions.

Conference: The “Excluded Third” in the Co-Production of Judaism, Christianity, and Islam

JUN 10–13, 2025 Villa Vigoni (Como Lake, IT)

Organized by Mercedes García-Arenal, Katharina Heyden, David Nirenberg, and Davide Scotto

Judaism, Christianity, and Islam are often understood as an ensemble of three (‘Abrahamic,’ ‘monotheistic,’ scriptural, or prophetic) religious communities and traditions. But often when adherents of two of these “sibling” religions interact, the third is treated as a figure to be marginalized, stigmatized, or instrumentally exploited vis-à-vis the others. This conference proposes to explore this dynamic of the excluded third.
