First published in 1906, Upton Sinclair's The Jungle is a groundbreaking work of American literature that exposed the brutal realities of immigrant life and industrial labor in turn-of-the-century Chicago. Following Jurgis Rudkus, a Lithuanian immigrant who arrives with dreams of prosperity, the novel lays bare the crushing poverty, unsafe working conditions, and ruthless exploitation faced by those employed in the city's meatpacking industry.

Shocking readers with its vivid depictions of corruption, filth, and human suffering, The Jungle helped spur major reforms in food safety and labor rights. Both a powerful social protest and a harrowing story of endurance, it remains one of the most influential novels of the twentieth century.
