The growing threat of antisemitism, racism and Islamophobia within the European political landscape poses urgent and difficult questions. These questions concern both commonalities and connections between these forms of prejudice and persecution, and differences regarding their discursive functions and the image of the ¿other¿ they project. In this volume we interrogate the specific forms which antiracism and anti-antisemitism take in the public sphere, their representation in scholarly discourses, and the fact that they increasingly seem to be at home in separate, and sometimes antagonistic, political and academic camps. We also address the conceptual resources and research tools required to study the unity that lies behind these varied phenomena. This collection has a new introduction and brings together papers that arose out of discussions in the European Sociological Association Network on Racism and Antisemitism, published in European Societies. The chapters relate to current issues in the area of racism and anti-Semitism such as the notable impact of the Israel-Palestine conflict on antisemitism in Europe, the contested ¿antizionist¿ humour of Dieudonn¿n France, relations between antisemitic and Islamophobic attitudes in Italy and Spain, the problem of antisemitic reactions to Islamophobia in Arab media, the historical relation of antisemitism to other kinds of racism in German literary discourse and how their study can be instructive for the investigation of antisemitism and Islamophobia today, the difficulties Marxists internationally have faced in addressing concerns about antisemitism, and current disconnections between racism and antisemitism in the human sciences. These papers raise fundamental issues of understanding the modern world. This book was originally published as a special issue of European Studies.
