Entartete Kunst

Degenerate art is the English translation of the German entartete Kunst, a term adopted by the Nazi regime in Germany to describe virtually all modern art. Such art was banned on the grounds that it was un-German or Jewish Bolshevist in nature, and those identified as degenerate artists were subjected to sanctions. These included being dismissed from teaching positions, being forbidden to exhibit or to sell their art, and in some cases being forbidden to produce art entirely.
