Director and founder of the avant-garde magazine La Gaceta Literaria (1927–1932), his work has been categorized as being part of the Futurist and Surrealist movement, while Stanley G. Payne has described him as the Spanish Gabriele d'Annunzio.
[10] Writing extensively about the decadence of modern society and fascism in his book 1932 Genio de España, Giménez Caballero called for a re-establishment of the Spanish Empire to its former glory under a Mussolini-led Latin union.
[12] Gimenez Caballero declared his support for the plans of Ramiro Ledesma Ramos in La Conquista del Estado (The Conquest of the State)[13] and became involved in his Juntas de Ofensiva Nacional-Sindicalista.
[4] One of the most bizarre of Giménez Caballero's actions was perhaps his unsuccessful attempt to marry Primo de Rivera's sister, Pilar, to Adolf Hitler, as a way to "soften" and "catholicize" the latter.
In later life he continued as a writer, winning his final writing prize, Premio Espejo de España, for his work Retratos españoles (bastante parecidos) in 1985 whilst also directing a series of documentary films.
[15] Giménez Caballero, who spent his last months following a surgical procedure to treat cataract in his house in the El Viso colony under an ill condition and dealing with auditive disorders, finally died on 14 May 1988.
