This episode looks at the dramatic combination of advancing industrialization, and the dirty business of coal mining both from the miners’ side and from the operators’ side. Specifically we’re going to talk about what happened when poor industrial relations, bigoted immigrant relations, and distrust between workers and bosses ignited violence, murder, undercover police work, and crime and punishment in the late 19th century coal fields of industrial America. In short, the Molly Maguires!
