Abstract Expressionism
A post-WWII American art movement defined by large-scale abstract paintings emphasizing spontaneous, gestural mark-making and the direct expression of emotional or psychological states.
Abstract Expressionism emerged in New York in the 1940s-1950s, making it the first major American art movement to achieve worldwide influence. Its core premise was that painting could communicate emotional and psychological truth through abstract form alone -- color, gesture, scale, and texture as primary language.
The movement had two broad tendencies: Action Painting, exemplified by Jackson Pollock's drip paintings and Willem de Kooning's slashing brushwork, where the physical act of painting was itself expressive; and Color Field painting, exemplified by Mark Rothko's luminous color rectangles and Barnett Newman's 'zip' paintings, where large areas of pure color created meditative emotional fields.
Abstract Expressionism was also political -- the CIA actually funded its international promotion during the Cold War as a demonstration of American freedom against Soviet Socialist Realism. This history has complicated its legacy, but the paintings themselves remain some of the most powerful in 20th-century art.
