Expressionism　　Expressionism is an art movement that produced a wealth of wonderful works of art, and the lives of the artists who created them were no less colorful and exciting. The word expressionism can be used to describe art from different times and places, most of them were part of a movement that took place in Germany from 1905 to 1920. They shared some of the beliefs. Those beliefs were that art should try to change society, to make it less conservative. It should express the energy of nature—following in the footsteps of Vincent van Gogh—-and personal feeling rather than simply representing nature. It should feel uncomfortable, which means it should challenge the traditional ways of looking at the world. This differed from the opinion of Henri Matisse who believed that art should be comfortable. Expressionist art should be inspired by folk art, and the art of what were then called primitive people, for example from Africa.　　The aim of the Expressionists was to express personal feeling about what they were painting rather than representing it exactly as it was. It should have strong colors and shapes, be relatively direct, untutored and unplanned and should still contain recognizable things, but not be realistic. The lines could be distorted, and the colors could be strengthened or changed as in the art movement that began in 1905 called Fauvism.　　Expressionism was more than a style in painting.

This freedom ended in 1933 when Hitler declared all Expressionists were degenerate. This led to them being sacked from their jobs or forced to leave Germany. In 1937 the Nazis took thousands of art works from German museums and put them in an enormous exhibition called the Degenerate Art Exhibition, to show how bad and decadent this art was. It presented a view of the world that went against their political and cultural ambitions to rid Germany of all inferior races.
