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 directed at punishing lynchings and mob violence.
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, but its passage was halted by a Southern Democratic filibuster in the U.S. Senate.
