Far more people saw the play than read the book. The various plays and scenes from the play were a staple of American Theater for 77 years. The impact of the book turned the Boston mob around from "always willing to help a hunt for a fugitive slave" to federal troops were necessary to keep slave hunters safe. The book was crafted in such a way that it appealed to socialist, abolitionist, christian evangicals and prohibionist. A good look at a book that changes the world.
