Orientalist philology brought people deemed Semitic together under the rubric of Semitism, and it subsequently broke up this forced grouping into the distinct categories of Jew, Arab, and Muslim. Chapter 3 demonstrates how the Dreyfus Affair exacerbated tensions between Jews, Muslims, and European residents of French colonial Algeria at the end of the nineteenth century. It explores the history of philological Semitism, discusses the legal status of Jews and Muslims in Algeria, and summarizes how the Dreyfus Affair affected Algerian politics and business. In order to think through the stylistics of French colonial anti-Semitism, the chapter examines pro-Jewish and anti-Jewish texts from the Algerian press of the 1890s. It ends with a close reading of Céline’s Bagatelles pour un massacre, demonstrating the way that popular literary philology reveals a lasting fracture between Jews, Arabs, and Muslims, while also exposing a process of psychological minoritization of the French majority population.
