The East-European change of regime found his ideological legitimation in the identification of fascism and «communism» in which the main discourse of this epoch concentrated. In the centre of this ideological legitimation there stands the Auschwitz-Gulag analogy. The author shows the political and ideological motivations, function and arguments of the newly actualised analogy of «AUSCHWITZ AND THE GULAG». The origin of this analogy was determined by the political aims of different political forces in the period of Cold war. After the change of regimes the identification of AUSCHWITZ AND THE GULAG became a rightist-conservative «narrative» in the historiography and in the streamline official political discourse. The function of this identification is to push out to the periphery of existence the system-critical thinking and movements as «extremes». The totalitarianism as a «theory» today has only one function in the historiography: the total criminalization of the history of the Soviet Union and «Communism» (see for example: «The Black Book of Communism»). The author shows that Auschwitz (Endlösung) and Gulag had different reasons and different aims, and also that to deny these differences means the historical relativization of the Endlösung. The author argues for the depolitization of this subject, which means to take seriously the archival research and scientific elaboration.
