Wars, forced migrations, genocides and other historical violences are brought about by crises and social fractures.This session proposes to deal with the social evocations and representations of these events in the processes of social communication, and invite to question the cultural creativity intervening in this field. The current memory culture of such events rests indeed on the capacity for people who have not lived them, to have in particular mental images of these facts. It also rests beyond traditional modes of transmission on social, teaching, artistic, etc. inventiveness that contemporaries of these facts and also people born after them have to share their knowledge, emotions, and feelings. It is thus a question of considering the various forms of cultural action and forms of politics identity based on memory intervening nowadays in the social phenomena of memory related to crises which have occurred in the past.
