Final answer:
Latin American architects post-WWII expressed their nations' cultural and political aspirations through Modernism and Postmodernism, incorporating regional characteristics and responding to social changes. They sought to establish a distinct Latin American identity in architecture, influenced by European training and reacting to local social and political dynamics.
Step-by-step explanation:
After World War II, Latin American architects expressed the cultural and political aspirations of their nations through a variety of means, including Modernism and Postmodernism. Influenced by their experiences abroad and the desire for a unique Latin American identity, they infused their work with regional character and social commentary. Architects, like their artistic counterparts, mirrored the social changes and political ideologies such as Marxism, Socialism, and Communism, which were prevalent during the time.
In the post-WWII era, expressionist architects, affected by traumatic war experiences and the German Revolution of 1919, adopted a romantic socialist agenda and sought to create Utopian outlook through their designs. This period saw the rise of ephemeral exhibition buildings. Likewise, during the 1960s, 70s, and 80s, architects turned away from the austerity of the International Style, embracing Postmodernism with its eclectic mix of ornamentation and historical reference as a reaction to the perceived exhaustion of modernist forms.
