Chicago literature is writing, primarily by writers born or living in Chicago, that reflects the culture of the city.
James Atlas, in his biography of Chicago writer Saul Bellow, suggests that "the city's reputation for nurturing literary and intellectual talent can be traced to the same geographical centrality that made it a great industrial power." When Chicago was incorporated in 1837, it was a frontier outpost with about 4,000 people. The population rose rapidly to approximately 100,000 in 1860. By 1890, the city had over 1 million people. Chicago's dynamic growth, as well as the manufacturing, economics, and politics that fueled this growth, can be seen in the works of writers like Carl Sandburg, Theodore Dreiser, Sherwood Anderson, Hamlin Garland, Frank Norris, Upton Sinclair, Willa Cather, and Edna Ferber.
Due to these rapid changes, Chicago writers of the late nineteenth and early twentieth centuries faced the challenge of how to depict this potentially disorienting new urban reality. Narrative fiction of that time, much of it in the style of "high-flown romance" and "genteel realism", needed a new approach to describe Chicago's social, political, and economic conditions. Chicagoans worked hard to create a literary tradition that would stand the test of time, and create a "city of feeling" out of concrete, steel, vast lake, and open prairie. Among the new techniques and styles embraced by Chicago writers were "naturalism," "imagism," and "free verse." Themes often centered on an exciting but dirty urbanism, as well as the quaint but dark and sometimes stultifying small town.
Chicago's early twentieth-century writers and publishers were seen as producing innovative work that broke with the literary traditions of Europe and the Eastern United States. In 1920, the critic H.L. Mencken wrote in a London magazine, the Nation, that Chicago was the "Literary Capital of the United States." Expressing the attitude that Chicago writers were creating a distinctive, new, and far from genteel literary idiom, he wrote, "Find a writer who is indubitably an American in every pulse-beat, snort, and adenoid, an American who has something new and peculiarly American to say and who says it in an unmistakable American way, and nine times out of ten you will find that he has some sort of connection with the gargantuan and inordinate abattoir by Lake Michigan."
