Modernism in art and literature marked a radical departure from traditional forms, emphasizing experimentation and individualism. It emerged in the late 19th and early 20th centuries, reflecting rapid technological advancements, urbanization, and the impact of World War I. Key figures like Picasso, Woolf, and Joyce pioneered new techniques such as stream of consciousness and Cubism. Modernist works explored themes of alienation, the subconscious, and the fragmentation of identity, challenging conventional notions of beauty and order.
