Hans Ibelings is a Dutch art historian and architecture critic. He has written extensively on architectural movements including postmodernism, modernism, deconstructivism, and supermodernism. The document discusses the key principles and influences of each movement. Modernism emphasized simplicity, rejection of ornament, and use of new materials like steel and glass. Postmodernism reacted against modernism with a return to traditional forms and reference to historical styles. Deconstructivism introduced non-rectilinear shapes and fragmentation. Supermodernism refers to a trend toward abstract, neutral architecture reflecting the last phase of modernism. Globalization is discussed as exerting influence on contemporary architecture through increased cross-cultural contact and the image of the global city
