The Red Scare period in the United States immediately following World War 1 from 1918 to 1920 was a time of rapid inflation, strikes, race riots, hyperinflation, mass roundups and deportations of foreign citizens. It also saw the expulsion of elected officials, incapacitated presidential leadership, new espionage laws, women's suffrage and prohibition, and a resurgence of the white supremacist Ku Klux Klan group that used threats and violence against immigrants, Jewish, Catholic and African American communities.
