In what way did anti-Semitism influence the Holocaust?

The growth of anti-Semitism in Germany led the Nazis to invade and conquer neighboring European nations.

Anti-Semitism in Germany led the Nazis to target groups such as Roma, socialists, and Jehovah's Witnesses.

The growth of anti-Semitism in Germany following World War I led the Nazis to carry out the genocide of Jewish people.

Anti-Semitism led the Nazis to use euthanasia against children with disabilities and adults with blindness, epilepsy, and other conditions.

All the answers are correct.

Explanation:

Anti-semitism influenced many other racist prejudices because it made scientific racism the most important "scientific" view of the Nazi government.

Because the racism against Jews was essential for Nazis, they looked at everything in racialized terms. It was a way for the racism against Jews to spread to all the spheres of life. Everything was about race and improving the human species through the production of a better human being based on the Aryans.

That's why anyone that was seen as an inferior race, not only Jews (but primarily them), like the Roma and Afro-Germans, was persecuted and killed by the regime.

People with disabilities were killed because they were seen as weak examples of the Aryans and thus should not create the next Aryan generation. This attempt to determine how the next humans will be born is called eugenics. That's also why homosexuals were also killed: they were believed to be sick.

The killing of socialists happened because their ideology did not agree to Nazi's racist views nor their closeness to the bourgeoisie and big capitalists.
