This is a presentation I created for a class that I just took on the Holocaust. In addition to the 6 million Jewish victims of the Holocaust, my presentation includes information about the 3.3 million Soviet POW's; about 300,000 Gypsies or Roma; 2 million non Jewish Poles; 250,000 mentally and physically disabled; 15,000 homosexuals; 5,000 Jehovah’s Witnesses, and an untold number of Roman Catholics. (The Nazi authorities in the concentration camps usually did not record the religious affiliation of a prisoner, with the exception of the Jehovah Witnesses; therefore, it is difficult to reliably estimate the total number of Catholic victims who were persecuted or killed because of some action or position connected to their Catholic faith).
