"The Holocaust was a deliberate and systematic extermination of European Jews during World War II. As the Allied Powers fought Nazi Germany's domination of Europe, Hitler's henchmen were carrying out a mass annihilation of the Jews in Europe at their numerous concentration camps. The total number of Jews murdered during this genocide has been estimated to be nearly 6 million. Besides European Jews, there were many other groups targeted for destruction. They included the handicapped, mentally ill, Gypsies, Jehovah's Witnesses, homosexuals and political dissidents. The following documents from the Eisenhower Library collection relate to the Holocaust."
