This book brings together the work of scholars who are exploring the entanglement of traditions and identities among the three major religio-ethnic groups in early modern Spain. The contributions reveal a broad shift in early modern Spanish historiography in recent decades. This text challenges a traditional conception according to which the historical trajectories of “Old Christians,” judeo-conversos (henceforth “conversos”), and moriscos (baptized Muslims and their descendants) were essentially separate. This volume appeals to students and researchers working in such fields of religious studies.
