Action painting
De Kooning as painter who knows the value of history, sought to understand the recent history of paintings thoroughly. In post-World War II era, de Kooning painted in an Abstract Expressionist style, also known as Action painting, whose painterly gesturalism transcended the conventional definitions of figuration and abstraction, and he substantially influenced art after World War II, becoming one of a group of artists that came to be known as the New York School. Jackson Pollock, Franz Kline, as well as Arshile Gorky are also regard as members of the New York avant-garde, with de Kooning championed as the leader of the movement.
