Antisemitism (also spelled anti-semitism or anti-Semitism) is hostility to, prejudice towards, or discrimination against Jews. A person who holds such positions is called an antisemite. Antisemitism is considered to be a form of racism.Antisemitism has historically been manifested in many ways, ranging from expressions of hatred of or discrimination against individual Jews to organized pogroms by mobs, police forces, or genocide. Although the term did not come into common usage until the 19th century, it is also applied to previous and later anti-Jewish incidents. Notable instances of persecution include the Rhineland massacres preceding the First Crusade in 1096, the Edict of Expulsion from England in 1290, the 1348–1351 persecution of Jews during the Black Death, the massacres of Spanish Jews in 1391, the persecutions of the Spanish Inquisition, the expulsion from Spain in 1492, the Cossack massacres in Ukraine from 1648 to 1657, various anti-Jewish pogroms in the Russian Empire between 1821 and 1906, the 1894–1906 Dreyfus affair in France, the Holocaust in German-occupied Europe during World War II and Soviet anti-Jewish policies. Though historically most manifestations of antisemitism have taken place in Christian Europe, since the early 20th century antisemitism has increased in the Middle East.
The root word Semite gives the false impression that antisemitism is directed against all Semitic people, e.g., including Arabs, Assyrians, and Arameans. The compound word Antisemitismus ('antisemitism') was first used in print in Germany in 1879 as a scientific-sounding term for Judenhass ('Jew-hatred'), and this has been its common use since then.The early Zionist pioneer Leon Pinsker, a professional physician, preferred the clinical-sounding term Judeophobia to antisemitism, which he regarded as a misnomer. The word Judeophobia first appeared in his pamphlet "Auto-Emancipation", published anonymously in German in September 1882, where it was described as an irrational fear or hatred of Jews. According to Pinsker, this irrational fear was an inherited predisposition. Judeophobia is a form of demonopathy, with the distinction that the Jewish ghost has become known to the whole race of mankind, not merely to certain races... Judeophobia is a psychic disorder. As a psychic disorder, it is hereditary, and as a disease transmitted for two thousand years it is incurable... Thus have Judaism and Jew-hatred passed through history for centuries as inseparable companions... Having analyzed Judeophobia as a hereditary form of demonopathy, peculiar to the human race, and represented Jew-hatred as based upon an inherited aberration of the human mind, we must draw the important conclusion, that we must give up contending against these hostile impulses, just as we give up contending against every other inherited predisposition. 
In the aftermath of the Kristallnacht pogrom in 1938, German propaganda minister Goebbels announced: "The German people is anti-Semitic. It has no desire to have its rights restricted or to be provoked in the future by parasites of the Jewish race."After 1945 victory of the Allies over Nazi Germany, and particularly after the full extent of the Nazi genocide against the Jews became known, the term antisemitism acquired pejorative connotations. This marked a full circle shift in usage, from an era just decades earlier when "Jew" was used as a pejorative term. Yehuda Bauer wrote in 1984: "There are no anti-Semites in the world ... Nobody says, 'I am anti-Semitic.' You cannot, after Hitler. The word has gone out of fashion."Reformation
Martin Luther, an ecclesiastical reformer whose teachings inspired the Reformation, wrote antagonistically about Jews in his pamphlet On the Jews and their Lies, written in 1543. He portrays the Jews in extremely harsh terms, excoriates them and provides detailed recommendations for a pogrom against them, calling for their permanent oppression and expulsion. At one point he writes: "...we are at fault in not slaying them...", a passage that, according to historian Paul Johnson, "may be termed the first work of modern antisemitism, and a giant step forward on the road to the Holocaust."Contemporary antisemitism
Post-WWII antisemitism
There have continued to be antisemitic incidents since WWII, some of which had been state-sponsored. In the Soviet Union, antisemitism has been used as an instrument for settling personal conflicts starting with the conflict between Joseph Stalin and Leon Trotsky and continuing through numerous conspiracy theories spread by official propaganda. Antisemitism in the USSR reached new heights after 1948 during the campaign against the "rootless cosmopolitan" (euphemism for "Jew") in which numerous Yiddish-language poets, writers, painters, and sculptors were killed or arrested. This culminated in the so-called Doctors' Plot in 1952.
Similar antisemitic propaganda in Poland resulted in the flight of Polish Jewish survivors from the country. After the war, the Kielce pogrom and the "March 1968 events" in communist Poland represented further incidents of antisemitism in Europe. The anti-Jewish violence in postwar Poland had a common theme of blood libel rumours.
