What events show the spread of the Red Scare in the US?

The Red Scare in the U.S. was marked by several significant events, including the Palmer Raids of 1919-1920, where Attorney General A. Mitchell Palmer led efforts to arrest and deport suspected radicals. The Sacco and Vanzetti case, highlighting fears of anarchism, also exemplified the era's paranoia. Additionally, the rise of the Communist Party and labor strikes, such as the Boston Police Strike of 1919, fueled public anxiety about communist influence in America. These events collectively contributed to a climate of suspicion and repression against perceived leftist threats.
