دادا (Dada) is an art movement that emerged in the early 20th century, around 1916, as a reaction to the horrors of World War I. It challenged traditional artistic values and norms, promoting chaos and irrationality. Dada artists used various mediums, including painting, sculpture, and performance, to express their disillusionment with society and culture. The movement is often associated with key figures such as Marcel Duchamp and Hannah Höch, who experimented with collage and ready-made objects. Dada laid the groundwork for later avant-garde movements, influencing Surrealism and Conceptual Art, and remains significant in discussions about the nature of art and creativity.
