Antisemitism dates back millennia and has been called “the longest hatred." The passions that fuel it — fear, envy, jealousy, resentment, suspicion, anger, xenophobic wariness and distrust — remain constant, but the forms this hatred takes change over time. The Institute for the Study of Contemporary Antisemitism (ISCA) at Indiana University focuses on high-level scholarly research into present-day manifestations of anti-Jewish animosity. Such animosity enters the public sphere through aggressive acts and hostile utterances. ISCA examines both of these and the relationships between them, especially the intellectual and ideological roots of the "new" antisemitism. We also seek to elucidate the social, cultural, religious, and political forces that nurture such hostility.
