Modernism arose in the late 19th and early 20th centuries in response to changes in Western society from industrialization. It rejected traditional forms of art, religion, and social organization as outdated. Modernism was marked by an intentional break from tradition and conservative views. Postmodernism emerged as a critique of modernism in the 1970s, abandoning strict modernist geometry for more flowing, embellished designs and a return to ornamentation on buildings. Postmodern urban areas are characterized by ethnic diversity, multinodal structures, spectacular centers, and high social polarization distinguished by consumption patterns.
