Purism is a style of modern art and architecture of the 20th century. It was founded in 1918 with the manifesto "Après le cubisme" by Charles-Edouart Jeanneret (Le Corbusier) and Amédée Ozenfant and is characterised by clear geometric forms, a limited choice of colours and a selection of a few everyday objects as pictorial subjects.
The 1918 pamphlet Apres le Cubisme (After Cubism), which is also regarded as the manifesto of Purism, marks its beginning. In Apres le Cubisme, Le Corbusier and Ozenfant criticise the current currents of synthetic and Orphic Cubism as too decorative and ornamental. A revised manifesto of Purism appeared in 1921 under the title "Purism" in the journal L'Esprit Nouveau.
