Answer :
Final answer:
The fear of Communism after WWI that led to discrimination against immigrants was called the Red Scare, a term encapsulating the widespread fear and paranoia of Communist infiltration and leading to events like the Palmer Raids and the trial of Sacco and Vanzetti. Therefore, the correct option is 1) Red Scare
Explanation:
The fear of Communism after World War I that contributed to greater discrimination against immigrants was known as the Red Scare. This was a period marked by intense fear and paranoia about the spread of Communism and socialism in the United States, similarly to the Bolshevik Revolution in Russia in 1917. The Red Scare affected the nation deeply, leading to suspicion and scrutiny of those who were perceived as foreign or who held radical political beliefs. High-profile cases such as the trial of Sacco and Vanzetti illustrated the extent of the paranoia, with immigrants and anyone viewed as a political radical at risk of discrimination or worse.
During the Red Scare, people from various backgrounds, including socialists, anarchists, and other left-leaning individuals and organizations, were targeted. An example of the government's efforts to suppress these groups was the Palmer Raids led by Attorney General A. Mitchell Palmer, which resulted in thousands of arrests and deportations without proper judicial process. The subsequent backlash to Palmer's oversteps and the eventual decline of the Red Scare movement did little to erase the period's impact on civil liberties and the American political landscape.
The repercussions of the Red Scare movement did not end with that period. It set the stage for the Second Red Scare, which came to be associated with the term McCarthyism in the 1950s. During this time, even more aggressive tactics were used to quash suspected Communist influence, affecting a wide range of people from government employees to Hollywood stars.
