How did the Holocaust affect the world?

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. Many American-run DP camps had horrific conditions, with inmates living under armed guard, as revealed in the Harrison Report.

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, the British Mandate of 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 Hagenah in British Mandate of 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. After the State of Israel declared independence in 1948, Jews were able to emigrate to Israel legally and without restriction. 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
