Die Brücke in the context of "Der Blaue Reiter"

Abstract expressionism in the United States emerged as a distinct art movement in the aftermath of World War II and gained mainstream acceptance in the 1950s, a shift from the American social realism of the 1930s influenced by the Great Depression and Mexican muralists. The term was first applied to American art in 1946 by the art critic Robert Coates. Key figures in the New York School, which was the center of this movement, included such artists as Arshile Gorky, Jackson Pollock, Franz Kline, Mark Rothko, Norman Lewis, Willem de Kooning, Adolph Gottlieb, Clyfford Still, Robert Motherwell, Theodoros Stamos, and Lee Krasner among others.

The movement was not limited to painting but included influential collagists and sculptors, such as David Smith, Louise Nevelson, and others. Abstract expressionism was notably influenced by the spontaneous and subconscious creation methods of Surrealist artists like André Masson and Max Ernst. Artists associated with the movement combined the emotional intensity of German Expressionism with the radical visual vocabularies of European avant-garde schools like Futurism, the Bauhaus, and Synthetic Cubism.

Ernst Ludwig Kirchner (6 May 1880 – 15 June 1938) was a German expressionist painter and printmaker. He was one of the founders of the artists group Die Brücke or "The Bridge", a key group leading to the foundation of Expressionism in 20th-century art. Kirchner volunteered for army service in the First World War, but soon suffered a breakdown and was discharged. His work was branded as "degenerate" by the Nazis in 1933, and in 1937 more than 600 of his works were sold or destroyed.
