The relation between Annals and marxism rested on the interest with the economic and social history. However, this “strange joint” that the historian English Marxist, Eric Hobsbawm calls it changes after the 1950’s. The crisis of the Marxism after the political events in 1956 and the vogue of the search for unconscious social after the appearance of structuralist anthropology of Claude Lévi-Strausse produce the retreat of the economic and social history, and the development of the history of mentalities. The history of Annals become the “new history”, and the relation ‘classique’ with the Marxism cannot maintained any more against a new reality.
Annals and the marxism meet again, and present a new orientation of the history of mentality in the 1970’s. This new relation was born in the contact between George Duby, historian of the mentalities, and Louis Althusser, marxist philosopher. Louis Althusser criticizes the stalinst marxism, and presents the theory of ideology as the material existence. The ideology, according to Louis Althusser, produces the real, the social, and also often plays a dominant role in the society, a function that organize the relation of production.
Les trois ordres ou l’imaginaire du fodalisme (1978) is the result of meeting between the history of Annals and the new Marxism. George Duby who introduces the theory of the ideology of Louis Althusse into his historical research opens a new dimension of the history of mentalities, and presents the possibility of new history. The relation with the marxism of Louis Althusser is continued in the succeeding works of Georges Duby, La Chevalier, la femme et le prtre (1981) and Dames du XIIe sicle(1995-1996).
