Postwar Modernism refers to a cultural movement that emerged after World War II, characterized by a break from traditional forms and a focus on innovation in art, literature, and architecture. This period saw the rise of abstract expressionism in painting, with artists like Jackson Pollock and Mark Rothko leading the way. Writers such as Samuel Beckett and T.S. Eliot explored new narrative techniques and themes of existentialism. In architecture, Postwar Modernism embraced new materials and technologies, resulting in structures that emphasized functionality and simplicity. Influential architects like Louis Kahn and Le Corbusier designed buildings that reflected the changing social landscape. This movement significantly shaped contemporary culture and continues to influence various artistic disciplines today.
