An anti-art movement born in [[Zürich]] in 1916 during [[World War I]], rejecting logic, reason, and bourgeois values through absurdity, satire, and chance-based creation. Key figures include [[Marcel Duchamp]]—whose [[Bicycle Wheel - Marcel Duchamp (1951)|Bicycle Wheel]] epitomizes the readymade's challenge to artistic convention—[[Hugo Ball]], [[Tristan Tzara]], and [[Hannah Höch]]. It arose as a nihilistic reaction against the rationalism that Dadaists believed had led to the war, challenging every convention of [[Modern Art]] and paving the way for [[Surrealism]].
