He coined the phrase "the Jews are our misfortune" which would later be widely used by Nazis.
In 1879 German journalist Wilhelm Marr published a pamphlet, Der Sieg des Judenthums über das Germanenthum.
a number of authorities have developed more formal definitions.
Holocaust scholar and City University of New York professor Helen Fein defines it as "a persisting latent structure of hostile beliefs towards Jews as a collective manifested in individuals as attitudes, and in culture as myth, ideology, folklore and imagery, and in actions—social or legal discrimination, political mobilization against the Jews, and collective or state violence—which results in and/or is designed to distance, displace, or destroy Jews as Jews." Elaborating on Fein's definition, Dietz Bering of the University of Cologne writes that, to antisemites, "Jews are not only partially but totally bad by nature, that is, their bad traits are incorrigible.
According to Lewis, antisemitism is marked by two distinct features: Jews are judged according to a standard different from that applied to others, and they are accused of "cosmic evil." Thus, "it is perfectly possible to hate and even to persecute Jews without necessarily being anti-Semitic" unless this hatred or persecution displays one of the two features specific to antisemitism.
There have been a number of efforts by international and governmental bodies to define antisemitism formally.
The term may be spelled with or without a hyphen (antisemitism or anti-Semitism).Late in 2013, the definition was removed from the website of the Fundamental Rights Agency.A spokesperson said that it had never been regarded as official and that the agency did not intend to develop its own definition.The United States Department of State states that "while there is no universally accepted definition, there is a generally clear understanding of what the term encompasses." For the purposes of its 2005 Report on Global Anti-Semitism, the term was considered to mean "hatred toward Jews—individually and as a group—that can be attributed to the Jewish religion and/or ethnicity." In 2005, the European Monitoring Centre on Racism and Xenophobia (now Fundamental Rights Agency), then an agency of the European Union, developed a more detailed working definition, which states: "Antisemitism is a certain perception of Jews, which may be expressed as hatred toward Jews.Rhetorical and physical manifestations of antisemitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions and religious facilities." It also adds that "such manifestations could also target the state of Israel, conceived as a Jewish collectivity," but that "criticism of Israel similar to that leveled against any other country cannot be regarded as antisemitic." It provides contemporary examples of ways in which antisemitism may manifest itself, including: promoting the harming of Jews in the name of an ideology or religion; promoting negative stereotypes of Jews; holding Jews collectively responsible for the actions of an individual Jewish person or group; denying the Holocaust or accusing Jews or Israel of exaggerating it; and accusing Jews of dual loyalty or a greater allegiance to Israel than their own country.The compound word antisemite was popularized in Germany in 1879 The origin of "antisemitic" terminologies is found in the responses of Moritz Steinschneider to the views of Ernest Renan.
