An offshoot of NeoPlasticism started by Theo Van Doesburg. In 1924 Van Doesburg, while still advocating the right angle, gave up the horizontal-vertical position of this angle and so came into conflict with the conception of NeoPlasticism formulated by Mondrian. In 1926, in his review De Stijl, Van Doesburg wrote an article in the form of a manifesto, in the course of which he said: 'Elementarism is partly a reaction against the too dogmatic application of Neo-Plasticism, and partly a consequence of Neo-Plasticism itself. What it seeks, above all, is a strict rectification of the Neo-Plastic ideas.' He then went on to explain what he meant by 'rectification'. As against the homogeneous construction of Mondrian's Neo-Plasticism, he proposed a heterogeneous form of expression, deliberately unstable, with inclined planes. He tried, in this way, to increase the dynamic effect, and renew the element of surprise. The painters Cesar Domela and Vordemberge-Gildewart, previously disciples of Mondrian, followed Van Doesburg.
