Anti-Semitism

Antisemitism (also spelled anti-Semitism or anti-semitism) is hostility, prejudice, or discrimination against Jews. A person who holds such positions is called an antisemite. Antisemitism is generally considered to be a form of racism.

The root word Semite gives the false impression that antisemitism is directed against all Semitic people. However, the compound word antisemite was popularized in Germany in 1879 as a scientific-sounding term for Judenhass "Jew-hatred", and that has been its common use since then.

Antisemitism may be manifested in many ways, ranging from expressions of hatred of or discrimination against individual Jews to organized pogroms by mobs, state police, or even military attacks on entire Jewish communities. Although the term did not come into common usage until the 19th century, it is now also applied to historic 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 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, official Soviet anti-Jewish policies, and Arab and Muslim involvement in the Jewish exodus from Arab and Muslim countries.
