This chapter studies Martina L. Weisz's Jews and Muslims in Contemporary Spain: Redefining National Boundaries (2019). This book aims to analyze “the place granted to Jews and Muslims in the construction of contemporary Spanish national identity, with a special focus on the transition from an exclusive, homogeneous sense of collective self toward a more pluralistic, open and tolerant one, in a European context.” This narrative of progress, however, is challenged by the excellent information provided in the book itself, which shows how these processes have been filled with contradictions and deep ambivalence, both historically and in the present, and how exclusionary nationalism has not been left behind. One of the book's richest contributions is its Jewish/Muslim comparative framework, which, as the author argues, is not usually undertaken. Ultimately, this book contains an abundance of useful information and insights for all those interested in Spain's relationship with its Muslim and Jewish minorities, the political and cultural negotiations of multiculturalism in Spain, and the way these relationships are affected by international events and diplomatic concerns.
