Modernism was a cultural movement in the early 20th century that rebelled against 19th century academic traditions. It embraced new aspects of modern life and believed that there is no absolute truth and that experiences are shaped by individual perception. Modernist works used experimental styles like stream of consciousness, fragmentation, and metaphor. In America, writers like Hemingway and Fitzgerald who lived abroad after WWI came to be known as the Lost Generation, documenting disillusionment with the war's destruction through sparse prose focused on inner consciousness.
