Dada Art is an avant-garde 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 conventions, promoting chaos and irrationality. Dada artists used a variety of mediums, including painting, sculpture, and performance, to express their discontent with society and the art world. Key figures in the Dada movement included artists like Marcel Duchamp and Hannah Höch, who often employed humor and absurdity in their work. Dadaism laid the groundwork for later movements such as Surrealism and Conceptual Art, influencing how art is perceived and created today.
