What was the red scare? What were the palmer raids

A "Red Scare" is the promotion of a widespread fear of a potential rise of communism or anarchism by a society or state. The name refers to the red flags that the communists used. The term is most often used to refer to two periods in the history of the United States which are referred to by this name.

The Palmer Raids were a series of raids conducted in November 1919 and January 1920 during the First Red Scare by the United States Department of Justice under the administration of President Woodrow Wilson to capture and arrest suspected leftists, mostly Italian and Eastern European immigrants
