During the Red Scare, thousands of anarchists and communists were hunted down and arrested.
Explanation:
The term Red Scare denotes two distinct periods of strong anti-communism in the United States: the First Red Scare, from 1917 to 1920, and the Second Red Scare, from 1947 to 1957. The First Red Scare was originated from the Russian Revolution, and was directed against socialist and anarchist workers and political radicalism. The Second Red Scare centered on an intense suspicion about alleged communists spies who influenced society or who infiltrated the United States Government after the end of World War II. In both periods, many Americans were arrested as they were suspected of being communists.
