Postmodern architecture is a style or movement which emerged in the 1960s as a reaction against the austerity, formality, and lack of variety of modern architecture, particularly in the international style advocated by Le Corbusier and Ludwig Mies van der Rohe. The movement was given a doctrine by the architect and architectural theorist Robert Venturi in his 1966 book Complexity and Contradiction in Architecture. The style flourished from the 1980s through the 1990s, particularly in the work of Venturi, Philip Johnson, Charles Moore and Michael Graves. In the late 1990s it divided into a multitude of new tendencies, including high-tech architecture, neo-classicism and deconstructivism. [1]
