German authorities established a Jewish ghetto in Błonie in December 1940, in order to confine the Jewish population of the town for the purpose of persecution, terror, and exploitation. The ghetto was liquidated in February 1941, when all its remaining 2,100 Jewish inhabitants were transported aboard the Holocaust train to the Warsaw Ghetto, the largest ghetto in all of German-occupied Europe with over 400,000 Jews crammed into an area of , or 7.2 persons per room. By the time Poland was liberated from German occupation, not a single Jewish ghetto remained.
