Jews were both sent to concentration camps and Soviet Labor camps.
The two largest groups of prisoners in the camps were the Polish Jews along with the Soviet prisoners of war (POWs) held without trial or judicial process. There were also large numbers of Romani people, ethnic Poles, Serbs, political prisoners, homosexuals, people with disabilities, Jehovah's Witnesses, Catholic clergy, Eastern European intellectuals and others (including common criminals, as the Nazis declared).
