The Dyer Anti-Lynching Bill was first introduced in 1918 by Representative Leonidas C. Dyer, a Republican from St. Louis, Missouri, in the United States House of Representatives as H.R. 11279.[1] It was intended to establish lynching as a federal crime. The Dyer Anti-Lynching Bill was re-introduced in subsequent sessions of Congress and passed by the U.S. House of Representatives on January 26, 1922,[2] but its passage was halted in the Senate by a filibuster by Southern Democrats, who formed a powerful block. Southern Democrats justified their opposition to the bill by arguing that lynchings were a response to rapes and proclaiming that lynchings were an issue that should be left for states to deal with.[2]
