In the context of the
Industrial Revolution, with the
emancipation of the Jews (1790s onwards) and the
Haskalah (the Jewish
Enlightenment of the 18th and 19th centuries), many Jews rapidly urbanized and experienced a period of greater social mobility. With the decreasing role of religion in public life and the simultaneous tempering of religious antisemitism, a combination of growing
nationalism, the rise of
eugenics, resentment of the perceived socio-economic success of Jews, and the influx of
Ashkenazi Jews from
Eastern Europe to Central Europe, soon led to the newer, and often more virulent, racist antisemitism.
Scientific racism, the
ideology that
genetics played a role in group behavior and characteristics, was highly respected and accepted as factual between 1870 and 1940. Historian
Walter Lacquer lists numerous influential figures such as economist
Eugen Duehring, composer
Richard Wagner, Biblical scholar
Paul de Lagarde, and historian-philosophers like
Houston Stewart Chamberlain as important figures in the rise of racial antisemitism. This acceptance of race science made it possible for antisemites to clothe their hatred of Jews in "scientific theory" and propose grand, sweeping political solutions in coming decades, from
relocation to Madagascar to
compulsory sterilization to mass extermination. In the
Third Reich (1933–1945), Nazis extended the logic of racial antisemitism,
enshrining racial antisemitic ideas into laws which assessed the "blood" or ethnicity of people (rather than their current religious affiliations), and prescribing—purely on that basis—the subsequent fate of those so assessed. When added to its views on Jewish racial traits which Nazi pseudoscience devised, the logic of racial antisemitism led to the
Holocaust of 1941–1945 as an attempt to eradicate conjured-up "Jewish traits" from the world.
Rise Modern European antisemitism originated in 19th century
pseudoscience which was used to justify the belief that the
Semitic peoples, including the Jews, were entirely different from the
Aryan, or
Indo-European populations, inherently inferior, and thus deserving social segregation. These theories extend at least as far back as
Martin Luther's 1543 treatise,
On the Jews and Their Lies, in which he wrote that Jews are a "base, whoring people, that is, no people of God, and their boast of
lineage,
circumcision, and
law must be accounted as filth". Though many argue that Luther expressed prejudice against Judaism as a religion, not Jews as a race, Franklin Sherman, editor of the American Edition of Luther's Works, writes that "Luther's writings against the Jews … are not ‘merely a set of cool, calm and collected theological judgments. His writings are full of rage, and indeed hatred, against an identifiable human group, not just against a religious point of view."
On the Jews and Their Lies was popular among supporters of the Nazi party during the early 20th century.
Hannah Arendt explained that before the 1870s, the Jewish population was a defined and detached group amongst western society. They were given rights and civil liberties as long as they served the states they lived in. However, due to their apolitical standing, they became an easy scapegoat and were visible to the public eye due to their position in state finance. Racial antisemites do not necessarily oppose the Jewish
religion; instead, Jews othered by ascribing them hereditary or genetic
racial stereotypes: greed, dirtiness, a special aptitude for money-making, aversion to hard work, clannishness and obtrusiveness, lack of social tact, low cunning, and especially, lack of
patriotism. Later,
Nazi propaganda also dwelt on supposed phenotypical differences, such as the shape of the "
Jewish nose". ==
