Nicola sacco and bartolomeo vanzetti were two (blank) immigrants accused of robbery and murder during the red scare of the 1920s.

The answer for the blank is "Italian."

These two Italian immigrants made national headlines after they were convicted of a crime despite a significant amount of evidence to prove that they were not guilty. Many individuals pointed to the fact that they were known anarchists as the reason why they were found guilty and eventually executed.

During this era, American society was fearful of anarchists and communists, as they felt these groups would try to overthrow the government. These fears stemmed from the Russian Revolution that Americans read about, as this revolution was the result of a communist uprising.

Democracy and darwinism would be my answer.
