The Jungle: The Jungle is a 1906 novel written by the American journalist and novelist Upton Sinclair (1878–1968).  Sinclair wrote the novel to portray the harsh conditions and exploited lives of immigrants in the United States in Chicago and similar industrialized cities.  Perhaps his main goal in exposing the meat industry and working conditions was to advance Socialism in the United States.  However, most readers were more concerned with his exposure of health violations and unsanitary practices in the American meatpacking industry during the early 20th century, greatly contributing to a public outcry which led to reforms including the Meat Inspection Act.  Sinclair famously said of the public reaction "I aimed at the public's heart, and by accident I hit it in the stomach."

It gained major popular support, with thousands joining End Poverty Leagues across the state.  EPIC never came to fruition due to Sinclair’s defeat in the 1934 election, but is seen as an influence on New Deal programs enacted by President Franklin D. Roosevelt.
