This article analyzes memory of the Shoah in post-War antiracist movements, notably the Mouvement contre le racisme, l’antisémitisme et pour la paix (MRAP) and the Ligue internationale contre le racisme et l’antisémitisme (LICA, today the LICRA). Jews’ experiences of the occupation were generally more visible in the discourse of the MRAP than in that of the LICA, which emphasized the universal aspect of Nazi crimes. In general, a fear of fascism returning was the main motivator in this early activation of memory of the Shoah. However, the two organizations also used this memory as a reference to protest against discriminations suffered by Arabs (MRAP) as well as antisemitism in Eastern Europe and the Arab world (LICA).
