After World War II, art moved away from modernism and toward postmodernism. Postmodern art explored identity, politics, and the relationship between art and mass culture. Styles included abstract expressionism, minimalism, pop art, conceptual art, and earthworks. Artists like Pollock, Rothko, and Judd created abstract works that emphasized process, emotion, and the qualities of materials over recognizable subjects. Later artists engaged popular culture and examined the definition of art through new media.
