Abstract Expressionism is an art movement that emerged in the United States in the 1940s and 1950s. It is characterized by spontaneous, automatic, or subconscious creation, emphasizing the act of painting itself rather than a representational form. Artists like Jackson Pollock and Mark Rothko sought to express emotional intensity through bold colors and dynamic forms. This movement marked a significant shift in the art world, moving away from traditional techniques and subjects. Abstract Expressionism played a crucial role in establishing New York City as a center for the art world, influencing countless artists and movements that followed.
