While Expressionism, of which Ernst Ludwig Kirchner'sSelf-Portrait as a Soldieris emblematic, was highly significant and powerful in the 1920s' Weimar Republic, political changes also changed artistic tastes. When Adolf Hitler and the Nazi Party took power in the 1930s, they targeted this kind of art for its association with bohemian lifestyles, intellectualism, and Jewish culture. In 1938, this piece of art was included in a famous exhibition of "Degenerate Art" put on by the Nazis. With such persecution, Kirchner's consistent mental health issues again came to the fore, and he committed suicide in 1938 by gunshot.

The bright, almost unnatural colors create a different perspective for the viewer and match more closely to other forms of abstract art.

The eclectic, improvisational nature of jazz had a wide influence in other artistic forms. In particular, visual artists sought to take some of jazz's extemporaneous elements and apply them to painting and sculpture. This idea greatly influence Jackson Pollock's "drip method" and other aspects of Abstract Expressionist art from the 1940s and 1950s.

Marilyn Diptych(1962) gets its form from early Christian diptych paintings that presented two images side by side. It was created using silkscreening, a method not used by early Christian painters. None of Warhol's Marilyns were made in the mosaic, relief, or fresco styles.

German forces seized the painting and, after the war, Adele Bloch-Bauer's husband Ferdinand sought to have it returned to his nieces and nephews. A long court battle followed, and it was only in 2006 that Austria returned it to the family.
