Modernism emerged as a literary movement in the early 20th century, breaking from traditional forms and conventions. Influenced by industrialization, urbanization, and World War I, it emphasized experimentation with form, style, and language to capture modern life's complexities. Key authors like T.S. Eliot, Ernest Hemingway, and Virginia Woolf explored themes of alienation, fragmentation, and the search for meaning. They employed innovative techniques such as stream-of-consciousness narration and nonlinear storytelling to reflect the chaotic nature of the modern world.
