In 1949, the World Jewish Congress called on the newly established Federal Republic of Germany to acknowledge responsibility and liability of the German people for the wrongs inflicted on the Jewish people by the Nazi regime. In 1950, the WJC opened an office in Frankfurt to function as a "listening post" on developments in Germany. In representations to the United States, Britain and France, the WJC detailed Jewish moral and material claims on Germany. In 1951, Nahum Goldmann, at the request of the Israeli government, established the Conference on Jewish Material Claims Against Germany (Claims Conference).
