The aim of this paper is to present a cultural approach to the Great War within the social and intellectual field of monarchist thought, reconstructing its practices and discourse about the conflict. By deciphering the contents and instruments of counterpropaganda, an analysis is made of the contribution of monarchists both to the formation of a social conscience (public opinion), which gradually became more and more opposed to the war effort, and to the creation of a social atmosphere that favored revolutionary action between 1914 and 1919.
