What is "judenfrei"

Judenfrei ("free of Jews") or Judenrein ("clean of Jews") was a Nazi term to designate an area " cleansed" of Jewish presence during The Holocaust.

While Judenfrei referred merely to "freeing" an area of all of its Jewish inhabitants, the term Judenrein (literally "clean of Jews") was also used. This had the stronger connotation that any trace of Jewish blood had been removed as an impurity.
