"For the Good of America... You Cannot Escape Your Responsibility," 1923

In 1912, the NAACP began a formal campaign to ban lynching. This 1923 broadside informed Americans about the numbers, causes and brutality of lynching. An anti-lynching bill was first introduced in Congress in 1918. A later version -- and others that followed -- failed to pass in the United States Senate. In June 2005, the Senate finally issued a formal apology for never having outlawed lynching.
