How did prejudice and discrimination affect the development of sociology in america in the late

19th and early 20th centuries?

Prejudice and discrimination affected the development of sociology in America due to the apartness Americans created towards black people, leaving them aside to grow in isolation, far from the cities and the "white race".

Explanation:

Having black people away and separating their children from their own, white Americans created their "own history" and a sentiment of white supremacy. As a consequence, universities did not allow black people until 1962: education was a privilege for white people, while it was luxury for black people.

Of course, white people were only Americans and some Europeans. Discrimination led to a lot of different decrees:

In 1907, the USA limited the immagration of Japanese.

In 1913, California prevented Asians to own lands and other goods. In 1920, other states did the same.

All up to the 20th century, Asians were limited in different areas of life, and that finally stablished a sense of patriotism and what is their naturally-given rights for white people, a sentiment that is still living in different regions.
