The Literary Digest, a popular weekly publication, tells the story of the August 1925
Ku Klux Klan march along Pennsylvania Avenue and the National Mall. Held August 8, 1925, an estimated 50,000 to 60,000 Klansmen participated in the event. Many were worried about violence at the event, but a strong police presence as well as the stipulation that marchers could not wear masks helped to keep the march peaceful.
