Abstract Expressionism

The painterly gestures of personal feelings
Hailed as the first American-born art movement to have a worldwide influence, Abstract Expressionism denotes the non-representational use of paint as a means of personal expression. It emerged in America in the 1940s, with lead protagonists including Jackson Pollock, Philip Guston, Robert Motherwell, Mark Rothko, and Willem de Kooning.
Abstract Expressionism spawned many different stylistic tendencies but two particularly prominent sub-categories: action painting, exemplified by de Kooning and Pollock, and color field painting, made most famous by Rothko.
