Surrealism is a cultural movement that began in the early 1920s (more specifically in 1924 when André Breton published his First Manifesto of Surrealism), and is best known for the visual art and writings of the group members. Surrealist works feature the element of surprise, unexpected juxtapositions and non sequitur; however, many artists and writers regard their work as an expression of the philosophical movement first and foremost, with the works being an artifact. Leader André Breton was explicit in his assertion that Surrealism was above all a revolutionary movement. In Belgium, the movement gets very active and quickly takes his distances with the principal founder Breton. The Belgian artists with a vivid personality create groups, magazines and elaborate theories. Even though René Magritte is the most renowned of Belgian surrealists, some other personalities leave their prints in art movement which looked for the union between the real and the imaginary world.
