The aftermath of the Jewish holocaust had a deep effect on society in both Europe and the rest of the world. Its impact has been felt in theological discussions, artistic and cultural pursuits, and political decisions.
German society largely responded to the enormity of the evidence for and the horror of the Holocaust with an attitude of self-justification and a practice of keeping quiet. Germans attempted to rewrite their own history to make it more palatable in the post-war era. For decades, West Germany and then unified Germany refused to allow access to its Holocaust-related archives in Bad Arolsen, citing privacy concerns. In May 2006, a 20-year effort by the United States Holocaust Memorial Museum led to the announcement that 30–50 million pages would be made available to survivors, historians and others.
The Holocaust and its aftermath left millions of refugees, including many Jews who had lost most or all of their family members and possessions, and often faced persistent antisemitism in their home countries. The original plan of the Allies was to repatriate these "displaced persons" to their countries of origin, but many refused to return, or were unable to as their homes or communities had been destroyed. As a result, more than 250,000 languished in displaced persons camps for years after the war ended.
With most displaced persons being unable or unwilling to return to their former homes in Europe, and with restrictions to immigration to many western countries remaining in place, Palestine became the primary destination for many Jewish refugees. However, as local Arabs opposed their immigration, the United Kingdom refused to allow Jewish refugees into the Mandate territory. Countries in the Soviet Bloc made emigration difficult. Former Jewish partisans in Europe, along with the Haganah in Palestine, organized a massive effort to smuggle Jews into Palestine, called Berihah, which eventually transported 250,000 Jews (both displaced persons and those who had been in hiding during the war) to Mandate Palestine. By 1952, when the displaced persons camps were closed, there were more than 80,000 Jewish former displaced persons in the United States, about 136,000 in Israel, and another 10,000 in other countries, including Mexico, Japan, and countries in Africa and South America.
The few Jews in Poland were augmented by returnees from the Soviet Union and survivors from camps in Germany. However, a resurgence of antisemitism in Poland, in such incidents as the Kraków pogrom on August 11, 1945, and the Kielce pogrom on July 4, 1946, led to the exodus of a large part of the Jewish population, which no longer felt safe in Poland. Anti-Jewish riots also broke out in several other Polish cities where many Jews were killed.
