History:
Wannsee Conference was a was a meeting of senior government officials of Nazi Germany and Schutzstaffel (SS) leaders, held in the Berlin suburb of Wannsee on 20 January 1942. The purpose of the conference, called by the director of the Reich Main Security Office SS-Obergruppenführer Reinhard Heydrich, was to ensure the cooperation of administrative leaders of various government departments in the implementation of the Final solution to the Jewish question (German: Endlösung der Judenfrage), whereby most of the Jews of German-occupied Europe would be deported to occupied Poland and murdered.
These notes were sent to all participants of the conference shortly after the meeting was concluded.
