[1] 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 the criminal perpetrators.
Most Jews were identified from late 1941 by the yellow badge as a result of pressure from Joseph Goebbels and Heinrich Himmler.
The terms judenrein and judenfrei have since been used in the persecution of global Jewish communities or Israel.
[citation needed] Establishments, villages, cities, and regions were declared judenfrei or judenrein after they were apparently cleared of Jews.
However, some Jewish people survived by being hidden and sheltered by friendly neighbours.
