The proposed paper analyzes the role of parent-child and intergenerational dynamics in conversion from Islam to Christianity among Kabyle immigrants in a diasporic church community who migrated from Algeria to France, and now form a cohort of converts in their community. The focus is on several cases and examples of narratives/accounts relating how generational experiences and relations with parents and wider political processes and structures in Algeria affected individual agency in decisions to convert. Data are based on this social/cultural anthropologist’s field research in and around Paris, France between 2009 and 2019. More broadly, the essay argues for the value of, but also critically engages insights from the following sets of literature: theories of intergenerational relationships; of religious conversion; diaspora cultures, and specifically, the historical and ethnographic background of Kabyles, who speak an Amazigh/Berber language and who have migrated from Algeria to France over several generations. In their testimonies and life histories, the current generation of immigrants who have recently converted to Christianity often evoke memories of relationships with older cohorts such as parents, as well as experiences of ancestors earlier on. The paper asks, what makes the convert cohort distinct in experience from their parents and earlier ancestor cohorts, but also, what experiences are held in common across generations, and how have these experiences shaped intergenerational relationships and impacted religious conversion among the diasporic converts? The paper argues that an emphasis on the politics of cultural intimacy and everyday life, informed by insights from interdisciplinary works as well as social/cultural anthropology, sheds light on generations, globalization, and conversion. Useful here is Karl Mannheim (1952)’s concept of generations formed through a common location in historical time such that there are shared events and experiences, and on an awareness of that historical location, as well as Cole and Durham’s (2006) insight that age cohorts are not strictly discrete, literal groups, but also constitute perspectives situated in wider social and historical events. Studies of religious and cultural encounters reveal processes of neither harmonious continuity nor complete rupture in conversion (Keane 2007; McIntosh 2009; Robbins 2007), and the findings of the field research presented here suggest that in immigrant converts’ memories, both harmonious inspiration and contentious conflict entered into decisions to convert.
