Résumé : COST Action IS1205 aims at advancingknowledge and promoting networking among histori-ans and social psychologists to analyse the role playedby social representations of history in Europe. Socialrepresentations of history are central to the identity ofgroups that may or may not form the majority in anygiven country. In Europe, these representations are atbest diverse, at worst fragmented, among various na-tional and ethnic groups, either in the same countryor across the continent. If left unexplored and unex-plained, these social (mis)representations can incite ad-verse emotions, in turn influencing group behavioursand possibly leading to intergroup rivalry. Bridging thetwo disciplines through representatives from 28 coun-tries, Action IS1205 addresses this issue by coordinat-ing research on the role of: social cognitive processes inshaping lay representations of history; lay representa-tion of history through the concepts of nationhood andidentities; social-psychological studies of the narrativetransmission of history through textbooks and the me-dia; lay representation of history and group-based emo-tions in shaping attitudes, intergroup conflict and re-conciliation processes.
