Abstract Expressionism is a type of art in which the artist expresses himself purely through the use of form and color. It non-representational, or non-objective, art, which means that there are no actual objects represented.
 
Now considered to be the first American artistic movement of international importance, the term was originally used to describe the work of Willem de Kooning, Jackson Pollock and Arshile Gorky.

The movement can be more or less divided into two groups: Action Painting, typified by artists such as Pollock, de Kooning, Franz Kline, and Philip Guston, stressed the physical action involved in painting; Color Field Painting, practiced by Mark Rothko and Kenneth Noland, among others, was primarily concerned with exploring the effects of pure color on a canvas.
