In Architecture Unbound noted architecture critic JOSEPH GIOVANNINI traces our current architecture landscape to the disruptive scientific advances and transgressive and progressive art movements that roiled Europe before and after World War I, and then to the social unrest and cultural disruptions of the 1960s. Cumulative shifts across disciplines and social systems established fertile new ground for the rise of an inventive, antiauthoritarian architecture that, in the 1970s, challenged the status quo. Built manifestoes in the 1980s led to digital inventions of the 1990s, and after the turn of the millennium to climax structures that now populate world capitals competing for cultural stature on the international stage.
