Auschwitz concentration camp
After World War II, the communist governments of the Soviet Union and Poland put up a memorial sign at Auschwitz. The sign said 4 million people died at Auschwitz. After the fall of the communist government in Poland in 1989, the sign was changed to say that 1.1 million people died there. People who try to deny the Holocaust use this difference to claim that the Holocaust was propaganda. However, the Holocaust is a fact of history, and the SS killed at least 1.1 million people at Auschwitz.
