Surrealism emerged in 1924 when French writer André Breton published his "Manifesto of Surrealism." This movement arose as a rejection of rationalism after the horrors of World War I. Seminal artists such as Salvador Dalí, René Magritte, Max Ernst, Luis Buñuel, and Man Ray developed the themes that defined the movement: dreams, disparate images, the subconscious, and social/political commentary.
