  5. 5. The 2015 Auschwitz-trial of Lüneburg: A Critical Discourse Analysis of Collective Memory of the Holocaust in Nazi-trials in Modern-day Germany.

    University essay from Malmö högskola/Kultur och samhälle

    Author : Astrid Juckenack; [2016]
    Keywords : collective memory; Auschwitz-trial; critical discourse analysis; Holocaust; Oskar Gröning; accessory to murder; impunity;

    Abstract : The points of departure in this thesis are the reciprocal relationship between the memories of human rights violations, the application of the relevant law and the understanding of what is criminal, as well as the recent trend in German courts to belatedly try low-profile Nazi-criminals. To explore these phenomena further, a critical discourse analysis incorporating historical elements is conducted on the 2015 trial of “the bookkeeper of Auschwitz” Oskar Gröning and the related media-reports.
