What effect did world war i have on artists' approach to their work?

The surrealism

In 1938 the International Exhibition of Surrealism took place in Paris, which marked the height of this movement before the war. Among others, Marcel Duchamp, Jean Arp, Dalí, Max Ernst, Masson, Man Ray, Óscar Domínguez and Meret Oppenheim participated. The exhibition offered the public especially an excellent sample of what surrealism had produced in the manufacture of objects.

With the outbreak of World War II, the Surrealists are dispersed, some of them (Dalí, Breton, Ernst, Masson) leave Paris and move to the United States, where they sow the germ for the future post-war American movements (abstract expressionism and Pop Art).
