In 1877, striking railroad workers rioted in Pittsburgh, Pennsylvania. The riot occurred early on during the Great Railroad Strike of 1877, a protracted strike wave that began on July 14, 1877 at Martinsburg, West Virginia in response to a Baltimore and Ohio Railroad wage cut.

The trial is often called the Scopes Monkey Trial and stands as a significant cultural and political defeat for America's Christian fundamentalists.
