Abstract: By taking an interest in the theatrical landscape in Brittany, crossed by the successive waves of dramatic decentralization, the dossier shows the richness of the links between professional and amateur practices. It emphasizes the role of the ADEC-Maison du théâtre amateur, an association founded in 1970, in the accompaniment of amateur practices and, in particular, of university theatre, but also in the structuring of the professional theatre landscape.
