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

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

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.
