Frederick Douglass 
Why is the Negro Lynched? [PDF ebook] 

one of the final essays written by Frederick Douglass before his death.
We have felt that the most fitting tribute that we, of the Anti-Caste movement, can pay to the memory of this noble and faithful life is to issue broadcast—as far as the means entrusted to us will allow—his last great appeal for justice (uttered through the pages of “The A.M.E. Church Review” only a few months before his death). A slanderous charge against Negro morality has gone forth throughout the world and has been widely credited. The white American has had his say both North and South. On behalf of the accused, Frederick Douglass claims, in the name of justice, to be heard.
