American writers like Hemingway, Fitzgerald, and Dos Passos moved to Paris in the 1920s to find community and escape censorship. Paris offered cheap living, mentors, and places to meet other artists at a time when reason seemed in doubt after WWI and the arts faced restrictions at home. Hemingway volunteered in WWI and was wounded, fueling his fiction writing in Paris where he mentored Fitzgerald. Dos Passos studied the effects of war and became a revolutionary writer. The community in Paris helped spawn modernist works and define the "Lost Generation."
