World Jewish Congress.

According to their own constitution, the World Jewish Congress is a voluntary association of representative Jewish bodies, communities and organisations throughout the world, organised to assure the survival and to foster the unity of the Jewish people. Its origins lie in the immediate aftermath of World War I in the cooperative efforts by Jewish communities around the world in religious, legal, political and relief matters. In the aftermath of World War II the World Jewish Congress played a central role in the creation of Jewish policies with regard to peace treaties, the prosecution and trial of Nazi war criminals and reparations for Holocaust survivors.
