While judenfrei refers merely to "freeing" an area of all of its Jewish inhabitants, the term judenrein (literally "clean of Jews") has the even stronger connotation that any trace of Jewish blood had been removed as an alleged impurity in the minds of Nazis. These terms of racial discrimination and racial abuse are intrinsic to Nazi antisemitism and were used by the Nazis in Germany before World War II and in occupied countries such as Poland in 1939. Judenfrei describes the local Jewish population having been removed from a town, region, or country by forced evacuation during the Holocaust, though many Jews were hidden by local people. Removal methods included forced re-housing in Nazi ghettos especially in eastern Europe, and forced removal or resettlement to the East by German troops, often to their deaths. Most Jews were identified from late 1941 by the yellow badge as a result of pressure from Joseph Goebbels and Heinrich Himmler.

Following the defeat of Germany in 1945, some attempts have been made to attract Jewish people back to Germany, as well as reconstruct synagogues destroyed during and after Kristallnacht.
