The present thesis, which has been accomplished with the support of the Fonds national de la Recherche du Luxembourg and within the research project “Partizip 2” at the University of Luxembourg (partizip.uni.lu) as well as in a cotutelle with the University of Lorraine, is an analysis of the memory of “Resistance” in Luxembourg, Alsace, Moselle and East Belgium. from 1944 to 2017. These territories were (de facto) incorporated within the Third Reich after the German invasion of Western Europe on the 10th of May of 1940. During the research, various asymmetries between these territories at the level of memory medias such as monuments, museums or legal statuses as a tribute to former resistance members were noticed. However, these memory asymmetries do not only appear between the state of Luxembourg and the French and Belgian regions, but also between the regions themselves. Thus the difference between the national and regional levels seems to be an accurate explanation if we compare the Grand-Duchy with the French and Belgian regions, but it does not allow us to understand the memory variations between these regions. Which are then the reasons that causes these memory asymmetries? Or in other words: which factors do contribute to the intensification of the memory of “Resistance”? In order to determine these factors, a comparative study of associations of former resistance members in Luxembourg, Alsace, Moselle and Est Belgium was undertaken, as they are crucial memory actors who often initiate the memory medias mentioned above. ; Notre thèse, qui a pu être réalisée grâce au soutien du Fonds national de la Recherche du Luxembourg et qui s’est faite dans le cadre du projet de recherche « Partizip 2 » de l’Université du Luxembourg et en cotutelle avec l’Université de Lorraine, est une analyse de la mémoire de la « Résistance » au Luxembourg, en Alsace, en Moselle et en Belgique de l’Est depuis 1944 à 2017.
