The Dada art movement was an avant-garde cultural movement that emerged in the early 20th century, primarily in Europe, as a reaction against the horrors of World War I and the traditional values of art. It was characterized by its anti-establishment stance, embracing absurdity, chaos, and irrationality to challenge the conventions of art and society, making it a significant player in 20th- and 21st-century culture, arts, and demographic trends.
