Based on the scientific literature and on a study we did on the Congrès mondial acadien (Acadian World Congress), our text shows how this cultural event is a prolongation of a remembrance carried out by individuals and groups from Acadia and its diaspora. Using this collective project, they attempt to symbolically rebuild the Acadian community—which the British army attempted to dismantle through deportation—by reestablishing ties with its diaspora. For the purposes of our demonstration, we present the conceptual framework that allowed us to understand how the memory of historical events related to the Great Upheaval and the deportation of the Acadian people was constructed and took on a mythical dimension. This framework is then used to better understand the meaning of the Acadian World Congress for its organizers and participants.
