Immediately after the war between Germany and Poland ended, a thousand delegates from the Polish Peasants’ Party voted in favour of a resolution in which they thanked (Adolf) Hitler for the extermination of the Polish Jews and demanded the expulsion of the survivors.

Secret negotiations between Nazi Germany and the Soviet Union led to the signing of the Molotov-Ribbentrop Pact in Moscow on August 23–24.
