Given the rise of nationalist and exclusionary movements on both sides of the Atlantic, which have mobilized against (and racialized) immigrant groups and communities of color, the symposium brings US- and Europe-focused research more directly into dialogue with regard to scholarship on religious responses to Islamophobia, the demonizing of migrants, and the broader attacks on growing racial and religious diversity. This full-day event is arranged around three sessions of relatively informal roundtables, addressing how religious transformations influence social action; the ways in which social mobilization has changed in the past fifty years and the effects on religious engagement with social justice; and the religious and social movement responses that may hold promise in advancing a more just and democratic future.
