On 29 November 1941, Heydrich sent invitations for a ministerial conference to be held on 9 December at the offices of Interpol at "Am Kleinen Wannsee 16". He changed the venue on 4 December to the eventual location of the meeting. He enclosed a copy of a letter from Göring dated 31 July that authorised him to plan a so-called Final solution to the Jewish question. The ministries to be represented were Interior, Justice, the Four-year plan, Propaganda, and the Reich Ministry for the Occupied Eastern Territories.
