“The Uncle Tom’s Cabin of wage slavery.” —Jack London. Sinclair’s masterpiece is an honest, sometimes brutal, tour de force that opened America’s eyes to the struggles and horrors many immigrants endured.

Welcome to Chicago during the early 1900s. Upton Sinclair’s The Jungle portrays the hardships of the immigrant working class in a way that changed literature and history. The story begins with Lithuanian immigrant Jurgis Rudkus, who takes a job at Brown’s slaughterhouse to try to earn enough money to stay afloat. His life becomes a constant struggle—he, his young wife, Ona, and the rest of his family eventually falling victim to a slew of unfortunate circumstances including exploitation, abuse, and for some even death.

From unsanitary and unsafe working conditions to poverty wages, the novel revealed to the American public the struggles immigrants encountered in Chicago’s meatpacking industry. Sinclair, a muckraking journalist, penned the bestselling narrative in an attempt to expose the evils of capitalism, and bring to light the extreme adversity these people faced not just in Chicago, but in industrialized cities across the country. By detailing numerous health violations in these workplaces, Sinclair’s novel caused public outrage and eventually led to the passing of the Meat Inspection Act and the Pure Food and Drug Act.
