Anti-Jewish sentiment

Antisemitism or Jew-hatred is hostility to, prejudice towards, or discrimination against Jews. A person who harbours it is called an antisemite. Whether antisemitism is considered a form of racism depends on the school of thought. Antisemitic tendencies may be motivated primarily by negative sentiment towards Jews as a people or negative sentiment towards Jews with regard to Judaism. In the former case, usually known as racial antisemitism, a person's hostility is driven by the belief that Jews constitute a distinct race with inherent traits or characteristics that are repulsive or inferior to the preferred traits or characteristics within that person's society. In the latter case, known as religious antisemitism, a person's hostility is driven by their religion's perception of Jews and Judaism, typically encompassing doctrines of supersession that expect or demand Jews to turn away from Judaism and submit to the religion presenting itself as Judaism's successor faith—this is a common theme within the other Abrahamic religions. The development of racial and religious antisemitism has historically been encouraged by anti-Judaism, which is distinct from antisemitism itself.

There are various ways in which antisemitism is manifested, ranging in the level of severity of Jewish persecution. On the more subtle end, it consists of expressions of hatred or discrimination against individual Jews and may or may not be accompanied by violence. On the most extreme end, it consists of pogroms or genocide, which may or may not be state-sponsored. Although the term "antisemitism" did not come into common usage until the 19th century, it is also applied to previous and later anti-Jewish incidents. Historically, most of the world's violent antisemitic events have taken place in Europe, where modern antisemitism began to emerge from antisemitism in Christian communities during the Middle Ages. Since the early 20th century, there has been a sharp rise in antisemitic incidents across the Arab world, largely due to the advent of Arab antisemitic conspiracy theories, which were influenced by European antisemitic conspiracy theories.

In recent times, the idea that there is a variation of antisemitism known as "new antisemitism" has emerged on several occasions. According to this view, since Israel is a Jewish state, expressions of anti-Zionist positions could harbour antisemitic sentiments, and criticism of Israel can serve as a vehicle for attacks against Jews in general.

The compound word was first used in print in Germany in 1879 as a " scientific-sounding term" for (), and it has since been used to refer to anti-Jewish sentiment alone. Due to the root word '' Semite'', the term is sometimes subject to an etymological fallacy whereby it is incorrectly assumed to apply to racist hatred directed at "Semitic people
