German art
The Nazi regime banned modern art; It was seen as degenerate art (ferman: entartete Kunst). Nazi ideology said that modern art had gone away from the norm of classical beauty. The 1920s to 1940s are considered the heyday of modern art movements. The government looked at avant-garde artists as enemies of the state and a threat to the German nation.  Many artists went into exile (or settled in other countries); Few came back after World War II.  Dix and Pechstein stayed. Nold stayed and made his "unpainted pictures" in secret after being forbidden (or having a prohibition) to paint. Beckmann, Ernst, Grosz, Feininger and others went to America. Klee went to Switzerland, where he died. Kirchner took his own life.
