Contemporary architecture arose from the Rejection of revivals, classicism, eclecticism, and all adaptations of previous styles to the building kinds of industrializing late 19th- and 20th-century society. Additionally, it arose out of attempts to make architectural forms and styles that could use and reflect the recently available construction technologies of structural iron and steel, reinforced concrete, and glass. Until the spread of postmodernism, the contemporary structure also implied the rejection of the applied ornament and decoration feature of premodern Western buildings. The thrust of contemporary architecture has been a rigorous concentration on buildings whose rhythmical arrangement of people and shapes states a geometric motif in light and color. This development was closely tied to the new construction types demanded by an industrialized society, such as office buildings housing corporate direction or government management. One of the most important trends and movements of modern architecture are the Chicago School, Functionalism, Art Deco, Art Nouveau, De Stijl, the Bauhaus, the International Style, the New Brutalism, and postmodernism.
