The memory of the Nazi past emerged in both postwar German states divided along political lines. In both states the political elites, oriented toward the future (building socialism in the GDR, returning Germany to the West in the FRG), tended not to focus on Nazi crimes, including the Holocaust. In both countries, however, there were minority groups which insisted on preservation of the Holocaust memory in Germany. In the GDR, it was a communist group (including Paul Merker) which had functioned in Mexico during the Nazi period which stressed the centrality of the anti-Jewish policy in Nazi Germany. In the FRG it was a group which included Social Democrats and President Heuss; it regarded the admission of German responsibility for the Holocaust as a precondition for the moral healing of the nation. Contrary to all expectations, it the FRG which faced the memory of the Holocaust, while in the "anti-fascist" GDR it was suppressed. With the rise of the SPD to power in the FRG, and the collapse of communism in the GDR in 1989, the Holocaust emerged as a major topic in German political discourse, preserved in reunified Germany.
