The word "antisemite" was first used to describe a politically motivated enemy of the Jews in 1879. The subject of antisemitism has often been focused on the Holocaust; however, current events and history have much to add to this discussion. For example, in 1995 a Japanese pseudo-Buddhist religious cult, imagining itself to be under attack by Jews, released sarin gas on the Tokyo subway, killing 12. From 1881 to 1900 there were 128 public accusations of Jewish "ritual murder" allegedly involving the killing of Christian children to use their blood for religious purposes. Entries in this encyclopedia span the period from ancient Egypt to the modern era. Key theoreticians of Jew-hatred and their written works, its permeation of Christianity and modern Islam, and its political, artistic, and economic manifestations are covered. This is the first comprehensive work that deals with the entire history of ideas and practices that engendered the Holocaust.
