Republic Steel Strike Riot Newsreel Footage

Republic Steel Strike Riot Newsreel Footage is a 1937 documentary film which tells the story of a strike at Republic Steel on Memorial Day, May 26, 1937, which escalated into a massacre in which 10 workers were killed, documented by this film.

The newsreel was produced by Paramount Pictures for their Paramount News series. In 1997, the film was deemed "culturally significant" by the United States Library of Congress and selected for preservation in the National Film Registry. The footage contained in the newsreel was banned from being shown in Chicago for fear of causing unrest, and later the Paramount News company agreed to refrain from screening the event elsewhere.
