Since the nazis separated the Aryans and Jews on the basis of their religion and their colour of eyes

C. Racial Science was introduced

Racial Science, also known as the pseudoscientific field of Eugenics, played a significant role in justifying Nazi ideas of race. The Nazis believed in the concept of a superior Aryan race and used racial science to support their ideologies. Here's how racial science was used to justify Nazi ideas of race:

1. Basis of Superiority: Racial science provided a supposed scientific basis for the Nazis' belief in the superiority of the Aryan race. They believed that Aryans were a pure and superior race, characterized by physical and intellectual qualities that made them superior to other races.

2. Promoting Social Darwinism: Racial science drew heavily from the theory of Social Darwinism, which applied the principles of natural selection and survival of the fittest to human societies. According to this ideology, the Aryan race was seen as the most advanced and fit for survival, while other races were considered inferior and destined for extinction or subjugation.

3. Measurement and Classification: Racial science developed methods to measure and classify different racial groups based on physical characteristics such as skull shape, eye color, and hair texture. The Nazis used these measurements to establish a hierarchy of races, with the Aryan race at the top and others ranked accordingly.

4. Propagation of Racial Purity: Racial science supported the Nazi regime's obsession with racial purity. They believed in the preservation and improvement of the Aryan race through eugenics, which involved selective breeding and sterilization to eliminate "undesirable" traits and individuals from the population.

5. Racist Legislation: The Nazis implemented racist legislation based on the principles of racial science. These laws restricted the rights and freedoms of non-Aryan groups, particularly Jews, and aimed at the exclusion and marginalization of these "inferior" races.

6. Propaganda and Indoctrination: The Nazis used racial science as a tool for propaganda and indoctrination. They disseminated scientific-sounding theories and ideas to convince the German population of the superiority of the Aryan race and the necessity of their racial policies.

In conclusion, racial science provided the Nazis with a distorted scientific framework to justify their beliefs in racial superiority and their policies of exclusion, discrimination, and ultimately, genocide. It was a key component in the propagation of Nazi ideas of race and the implementation of their racist agenda.
