In the last 20 years, there have been countless public discussions about anti-Semitism. At the same time, anti-Semitism has become increasingly aggressive and violent, with right-wing and Islamist groups in particular claiming responsibility for anti-Semitic violence. This book presents the key occurrences and discussions relating to this issue in a condensed form by providing an overview of the individual facets of anti-Semitism and by classifying them according to their development. The interplay between right-wing, left-wing and Islamist anti-Semitism plus that in the mainstream of society is a characteristic of anti-Semitism since 9/11.
