Published in 1906, The Jungle originally appeared in serial form as The Appeal to Reason in a socialist newspaper. It was so well received that Sinclair Lewis republished the work as The Jungle in novel form. Chronicling the plight of Jurgis and Ona, Lithuanian immigrants to Chicago, the story deals with the plight of the workers in the packyards of Chicago. The Jungle had a deep and immediate political impact sending shockwaves throughout the United States and causing cries for labor and agricultural reform. This is a powerful book that made a significant social impact on the country.
