Some previous research about Georges Higuet, an unknown Belgian painter, has led me to become interested in artists’ associations in the Belgian Hainaut during the twentieth century. Global studies had never been done before, even though, surprisingly enough, many groups were born in as little an area as a French department. That is why I have decided to tell the story of art groups in the Belgian province of Hainaut. As far as this subject is concerned, either the literature is superficial or even incomplete, or the studies, which in this case may often be solid, quote some more or less known associations. My purpose is to provide as accurate a picture as possible of the whole question, making this research definitely original and relevant. In order to offer a rigorous perspective, the collection of documents, an essential part of my research, has been done in different ways, as regards art book reading, Salon booklets, press reports and artwork photograph research, as well as some artists’ meetings, provided they are still alive. A history of art associations has been traced little by little, which should be as complete as possible, in spite of a few gaps. In the end, this work proposes a data set which will be helpful to researchers, and more generally to all the people interested in their country’s history. Finally, this research shows how those groups, each of them witnessing the evolution and formation of taste, have made it easier to constitute a regional artistic heritage. ; Héritière d’un passé artistique prestigieux, la province wallonne de Hainaut a vu fleurir nombre de sociétés d’artistes, dont ce travail constitue une première synthèse. Dans les dernières décennies du XIXe siècle et jusqu’à la Première Guerre mondiale, sont apparus les premiers cercles, d’abord à Tournai (Cercle Artistique de Tournai), puis Mons (Bon Vouloir, L’Essaim) et La Louvière (Les Amis de l’Art). Pendant l’entre-deux-guerres, le phénomène s’est amplifié : à la suite de ces trois centres urbains, la ville de Charleroi a ainsi ...
