This paper investigates how Alevi individuals in the diaspora negotiate religious belonging, identity, and institutionalization in the context of socio-political marginalization. Drawing on a set of biographical-narrative interviews with Alevi respondents across generations, the study highlights the role of diasporic experience in reshaping religious self-understanding and collective organization. The findings reveal shifting modes of self-identification—particularly among younger generations—ranging from detachment from Islam to the assertion of an autonomous Alevi tradition. These developments challenge dominant categorizations within both Islamic and secular discourses and expose the inadequacy of existing legal and scholarly frameworks to capture the plural and evolving nature of Alevi religiosity in diaspora. The paper contributes to current debates on religious minorities, post-migration identities, and the dynamics of recognition and exclusion in pluralist societies.
