Adolf Hitler announced the party's program on 24 February 1920 before approximately 2,000 people in the Munich Festival of the Hofbräuhaus and within the program was written “The leaders of the Party swear to go straight forward, if necessary to sacrifice their lives in securing fulfillment of the foregoing points” and declared the program unalterable.[1] The National Socialist Program originated at a DAP congress in Vienna, then was taken to Munich, by the civil engineer and theoretician Rudolf Jung, who having explicitly supported Hitler had been expelled from Czechoslovakia because of his political agitation.[2]
