A Dutch art movement founded in [[Amsterdam]] in 1917, advocating pure abstraction through the reduction of form to geometric elements and the use of only primary colors plus black and white. Key figures include [[Piet Mondrian]]—whose [[Composition - Piet Mondrian (1921)|Composition]] and later [[Broadway Boogie Woogie - Piet Mondrian (1942)|Broadway Boogie Woogie]] trace the movement's evolution—[[Theo van Doesburg]], and architect [[Gerrit Rietveld]]. It responded to the chaos of [[World War I]] by seeking universal visual harmony, building on the abstraction of [[Cubism]] and influencing the [[Bauhaus]] and [[Modernist Design]].
