Why was there a rise in nativism after world war 1

There was a rise in Nativism because the people were afraid that the communism would spread.

Explanation:

"Nativism” is a political party which promotes interests of its native residents and not of the immigrants.

Immigration reached its new heights by the end of 19th century in US. There were diverse cultures, new languages and customs and racial enmity.

In reaction to all this, many supported Nativism. Nativists also fueled a sense of fear by supposing that there was a foreign threat. They pointed the assassinations of the “Spanish prime minister” in 1897, the “Italian” king in 1900, and even President "William McKinley" in 1901 as evidence of all this.
