Dada art is a form of artistic expression that emerged in the early 20th century in response to World War I. It is often seen as a precursor to modern art movements, such as Surrealism and Fluxus. Dada artists used a variety of media, including collages, assemblages, photomontage, and performance art, to challenge traditional aesthetic conventions. They often used irony and satire to explore themes of absurdity, nihilism, and anti-art. Dada art is characterized by its playful, rebellious, and sometimes confrontational approach to the creative process. Its legacy continues to shape and influence contemporary art practices today.
