How many non-Jews were killed in German concentration camps?

Estimates suggest that millions of non-Jews were killed in German concentration camps during the Holocaust and World War II. This group included Poles, Soviet prisoners of war, Romani people, disabled individuals, political dissidents, homosexuals, and others deemed undesirable by the Nazi regime. While exact figures are difficult to determine, it is believed that approximately 5 to 6 million non-Jewish victims perished in these camps. The total number of victims, including Jews, is estimated to be around 11 to 12 million.
