This short definition is to a certain extent inadequate because there are a range of interpretations as to the origin and rise of Modern Architecture, and what constitutes Modern Architecture itself, depending on the frame of reference of the historian.
Some historians see the evolution of Modern Architecture as closely tied to the Project of Modernity and hence to the Enlightenment, the Social/ Political revolutions, general progress of mankind, and so on. Here the origin is placed much earlier, modern town planning and housing are also brought into the range. Others see technological and engineering developments as key to the rise of Modern architecture. Hence the usage of new materials such as iron, steel, concrete and glass is ascribed an important place, with the Crystal Palace by Joseph Paxton to house the Great Exhibition of 1851 or the apartment building by Auguste Perret serving as important examples. Some historians see the rise of Modern architecture as a reaction to the Eclectism and poor taste of the Victorian Era fuelled by the possibilities of theIndustrial Revolution. Here precursor movements such as the Arts and Crafts Movement and the Art Nouveau are brought in to bridge the gap. Yet others cite modern art movements such as Cubism and De Stijl as fundamentally altering the way in which buildings are designed by bringing in qualities of art into architecture.
All these reasons are equally valid.
Finally Modern Architecture is characterised by the way in which it
Modern architecture was disseminated through individuals( Le Corbusier, Mies van der Rohe, Frank Lloyd Wright), movements (De Stijl, Art Nouveau) and schools (Bauhaus). The Bauhaus, the architecture school in Germany started in 1919, was the most influential school and under various directors the ideology differed slightly. However, the fundamental aim was to unite art and technolgy to produce good design. With the rise of the Nazis, the important people associated with the school, and hence its ideas, shifted to the United States. Modern architecture began to be called the International style after the exhibition conducted in the Museum of Modern Art, New York, United States, showcasing works of Modern Architecture.
A criticism of Modern Architecture began from the 1960s on the grounds that it was universal,sterile, elitist and lacked meaning. The rise of Postmodernism is attributed to the general disenchantment with Modern architecture.
