SILENT MARCH DOWN FIFTH AVENUE 
On July 28, 1917, fifty thousands African-Americans marched in silent protest down Fifth Avenue from 57th and 23rd Street to protest lynchings and violence, and to demand their civil rights. As reported in The New York Times, “without a shout or a cheer they made their cause known through many banners which they carried, calling attention to 'Jim Crowism,' segregation, disenfranchisement, and the riots of Waco, Memphis, and East St. Louis.” The Silent March, organized by the NAACP, has been commemorated with exhibitions. Its centennial was even honored on the Google home-page. It should be marked on Fifth Avenue as well.
