Founded in 1866 in Pulaski, Tennessee, the Ku Klux Klan combated post-Civil War reforms and terrorized freed African Americans in the former Confederacy. Dormant for decades, by the mid-1920s a reconstructed Klan was again a powerful political force in both the South and the North. Mainly due to the changing social times of the 1920s, the Great Migration, the influx of immigrants, and the fear of communists and anarchists, the Klan began spreading hatred against African Americans, immigrants, Catholics, and Jews across the country.
