What effect did World War 1 have on art movements in the 1920s?

World War I profoundly influenced art movements in the 1920s, leading to a shift towards modernism and abstraction as artists sought to convey the trauma and disillusionment of the war. Movements such as Dada and Surrealism emerged, challenging traditional aesthetics and embracing chaos and irrationality as responses to the horrors of conflict. Artists like Marcel Duchamp and Salvador Dalí explored new forms and techniques, reflecting a break from conventional narrative and realism. This period also saw a rise in avant-garde experimentation, as creators sought to redefine art's purpose in a rapidly changing world.
