An overview of the history of antisemitism throughout the ages, with emphasis on the modern period. Ch. 3 (pp. 39-70) deals with ancient and medieval anti-Judaism, and the rest of the book describes antisemitism from the Enlightenment to the present day. The 19th century saw the development of racialism and theories of a Jewish conspiracy. The dramatic rise of antisemitism after World War I ended with the Holocaust. Afterwards antisemitism appeared in the guise of anti-Zionism, Holocaust denial, neo-fascism and other forms. Subsequently, antisemitism was adopted by the Left and by the Muslim world. Nowadays the radical Left, radical Right, and radical Muslim antisemitisms are undistinguishable and form all kinds of alliances with one another. It is difficult to differentiate between anti-Zionism and antisemitism. At present, antisemitism, by whatever name, is still much more than a mere historical memory.
