The Haavara Agreement (Hebrew: הֶסְכֵּם הַעֲבָרָה‎ Translit.: heskem haavara Translated: "transfer agreement") was an agreement between Nazi Germany and Zionist German Jews signed on 25 August 1933. The agreement was finalized after three months of talks by the Zionist Federation of Germany, the Anglo-Palestine Bank (under the directive of the Jewish Agency) and the economic authorities of Nazi Germany.
