The Modern Movement of architecture represents a huge change in the design of buildings. Away from the traditional construction techniques the Modern Movement began in Europe and spread to the United States in the 1920s. European architects like Eliel Saarinen, Le Corbusier , Walter Gropious, and Mies van der Rohe expressed new designs in the early 20th century and abandoned past designs and started to exploring new materials and technology in their work. The Art Deco and Modern style were promoted at the 1925 Exposition des Arts Decoratifs in Paris. At the Exposition people thought they both represented an exotic look for new buildings.
The impact of both Art Deco and Modern styles soon brought in a new type of style International style, which left a lasting impression on the urban landscape. The International style soon announced a new “modern” view of style and purpose of architecture. Inspired by the Cubism of modern art in Europe, the boxy shapes of International style buildings embodied a new social theory of architecture as well. With the new construction technologies, the International style was portrayed as a new kind of architecture designed to meet the needs of the common people in the Machine Age.
