After liberation, many Jewish survivors feared to return to their former homes because of the antisemitism (hatred of Jews) that persisted in parts of Europe and the trauma they had suffered. Some who returned home feared for their lives. In postwar Poland, for example, there were a number of pogroms (violent anti-Jewish riots). The largest of these occurred in the town of Kielce in 1946 when Polish rioters killed at least 42 Jews and beat many others.

With few possibilities for emigration, tens of thousands of homeless Holocaust survivors migrated westward to other European territories liberated by the western Allies. There they were housed in hundreds of refugee centers and displaced persons (DP) camps such as Bergen-Belsen in Germany. The United Nations Relief and Rehabilitation Administration (UNRRA) and the occupying armies of the United States, Great Britain, and France administered these camps.
