Antisemitism is defined as hostility and prejudice toward Jews as well as taking discriminatory action towards Jewish people. Some consider antisemitism to be a form of racism.
The word antisemitism finds its roots in the German word antisemitisch, first used in 1860 by Austrian Jewish scholar Moritz Steinschneider, in his work regarding false ideas of "Semitic races" in comparison to "Aryan races." However, the discriminatory ideas and actions towards Jews have existed since long before the term was coined.
Early incidents of antisemitism and anti-Jewish persecution include the Edict of Expulsion from England in 1290, the persecution of Jews across Europe during the Black Death from 2348 - 1351, and the Spanish Inquisition and expulsion from Spain in 1492.
The 20th century saw both the Holocaust, the genocide of European Jews, and the expulsion of Jews from countries across the Middle East, leading to the displacement of approximately 850,000 Mizrahi Jews.
In recent years both Europe and the US have seen a steady increase in antisemitic incidents, and 90% of Jews in the European Union have said that they feel this is a serious problem.
