In the 1970s, in different European countries, collectives for homosexual emancipation began to organize. Either as homophile groups of reformist character or as revolutionary fronts of liberation, the social movements of this period were characterized by the production of contestational texts against the discourse of hegemony. These publications, in addition to the positions and proposals of the collectives, document the relations of solidarity among them, as well as the exchange of knowledge, information and ideas. This paper presents the texts that document the relationships that existed between the Italian and Spanish collectives, which, in turn, might have been created thanks to the solidarity support of other movements.
