Modernism emerged in the early 1900s as a rejection of 19th century optimism and morality. It presented a deeply pessimistic view of culture disillusioned by World War I. Modernist works transformed literature, art, music and more with a feeling of lost community. Influential modernist writers like T.S. Eliot, Ernest Hemingway and Virginia Woolf addressed these themes. World War I introduced modern weapons and was one of history's bloodiest conflicts, influencing modern literature to focus on cultural degradation.
