>The Wannsee Conference (German: Wannseekonferenz, German pronunciation: [ˈvanzeːkɔnfeˌʁɛnt͡s] ) 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 Security Main Office SS-Obergruppenführer Reinhard Heydrich, was to ensure the co-operation of administrative leaders of various government departments in the implementation of the Final Solution to the Jewish Question, whereby most of the Jews of German-occupied Europe would be deported to occupied Poland and murdered. Conference participants included representatives from several government ministries, including state secretaries from the Foreign Office, the justice, interior, and state ministries, and representatives from the SS. In the course of the meeting, Heydrich outlined how European Jews would be rounded up and sent to extermination camps in the General Government (the occupied part of Poland), where they would be killed.[1]
>The attendees from the Reich civilian ministries were high level administrators. Most were either the state secretary or an undersecretary. With the cabinet not meeting regularly, meetings between the state secretaries were the chief means of policy coordination among agencies.[33] The process of disseminating information about the fate of the Jews was already well underway by the time the meeting was held, and several of the attendees were aware that changes to the Jewish policy were already underway.[43] In addition to the invited guests, Heydrich instructed several SS officials from his RSHA component to attend.[44] In all, 15 officials attended the conference.[c]
