The "post-war avant-garde" refers to a movement in art, literature, and culture that emerged after World War II, characterized by innovative and experimental approaches. Artists and writers sought to break away from traditional forms and conventions, often reflecting the chaos and trauma of the war. This period saw the rise of various movements, including Abstract Expressionism, Surrealism, and Fluxus, which challenged established norms and embraced new ideas. Key figures in the post-war avant-garde included Jackson Pollock, Samuel Beckett, and John Cage, who pushed boundaries in their respective fields. The movement emphasized individual expression and often incorporated elements of chance, spontaneity, and collaboration. This era significantly influenced contemporary art and culture, paving the way for future artistic explorations.
