André Breton in the context of "Surrealist cinema"

Surrealism is an art and cultural movement that developed in Europe in the aftermath of World War I in which artists aimed to allow the unconscious mind to express itself, often resulting in the depiction of illogical or dreamlike scenes and ideas. Its intention was, according to leader André Breton, to "resolve the previously contradictory conditions of dream and reality into an absolute reality, a super-reality", or surreality. It produced works of painting, writing, photography, theatre, filmmaking, music, comedy and other media as well.

Works of Surrealism feature the element of surprise, unexpected juxtapositions and non sequitur. However, many Surrealist artists and writers regard their work as an expression of the philosophical movement first and foremost (for instance, of the "pure psychic automatism" Breton speaks of in the first Surrealist Manifesto), with the works themselves being secondary, i.e., artifacts of surrealist experimentation. Leader Breton was explicit in his assertion that Surrealism was, above all, a revolutionary movement. At the time, the movement was associated with political causes such as communism and anarchism. It was influenced by the Dada movement of the 1910s.

The Surrealist Manifesto refers to several publications by Yvan Goll and André Breton, leaders of rival surrealist groups. Goll and Breton both published manifestos in October 1924 titled Manifeste du surréalisme. Breton wrote a second manifesto in 1929, which was published the following year, and in 1942, a reflection or a commentary on the potential for a third manifesto, exploring how the Surrealist movement might adapt to changing times.

Dada (/ˈdɑːdɑː/) or Dadaism was an international art movement that developed in the context of the Great War and Futurism first established in Zürich, Switzerland, and later quickly spread to Berlin, Paris, New York City and a variety of artistic centers in Europe and Asia. The Dada movement's principles were first collected in Hugo Ball's Dada Manifesto in 1916. Ball is seen as the founder of the Dada movement. Key figures in the movement included Hugo Ball, Emmy Hennings, Jean Arp, Johannes Baader, Marcel Duchamp, Max Ernst, Elsa von Freytag-Loringhoven, George Grosz, Raoul Hausmann, John Heartfield, Hannah Höch, Richard Huelsenbeck, Francis Picabia, Man Ray, Hans Richter, Kurt Schwitters, Sophie Taeuber-Arp, Tristan Tzara, and Beatrice Wood, among others. The movement influenced later styles like the avant-garde and downtown music movements, and groups including Surrealism, nouveau réalisme, pop art, and Fluxus.

Lettrism is a French avant-garde movement, established in Paris in the mid-1940s by Romanian immigrant Isidore Isou. In a body of work totaling hundreds of volumes, Isou and the Lettrists have applied their theories to all areas of art and culture, most notably in poetry, film, painting and political theory. The movement has its theoretical roots in Dada and Surrealism. Isou viewed his fellow countryman Tristan Tzara as the greatest creator and rightful leader of the Dada movement, and dismissed most of the others as plagiarists and falsifiers. Among the Surrealists, André Breton was a significant influence, but Isou was dissatisfied by what he saw as the stagnation and theoretical bankruptcy of the movement as it stood in the 1940s.

In French, the movement is called Lettrisme, from the French word for letter, arising from the fact that many of their early works centred on letters and other visual or spoken symbols. The Lettristes themselves prefer the spelling "Letterism" for the Anglicised term, and this is the form that is used on those rare occasions when they produce or supervise English translations of their writings: however, 'Lettrism' is at least as common in English usage. The term, having been the original name that was first given to the group, has lingered as a blanket term to cover all of their activities, even as many of these have moved away from any connection to letters. But other names have also been introduced, either for the group as a whole or for its activities in specific domains, such as 'the Isouian movement', 'youth uprising', 'hypergraphics', 'creatics', 'infinitesimal art' and 'excoördism'.

Nadja (1928) is the second book published by the French surrealist André Breton. It begins with the question "Who am I?"

It is based on Breton's actual interactions with a young woman, Nadja (actually Léona Camille Ghislaine Delacourt 1902–1941), over the course of ten days, and is presumed to be a semi-autobiographical description of his relationship with a patient of Pierre Janet. The book's non-linear structure is grounded in reality by references to other Paris surrealists such as Louis Aragon and 44 photographs.

Philippe Soupault (2 August 1897 – 12 March 1990) was a French writer and poet, novelist, critic, and political activist. He was active in Dadaism and later was instrumental in founding the Surrealist movement with André Breton. Soupault initiated the periodical Littérature together with writers Breton and Louis Aragon in Paris in 1919, which, for many, marks the beginnings of Surrealism. The first book of automatic writing, Les Champs magnétiques (1920), was co-authored by Soupault and Breton.
