While the 'final solution' meant that all Jews were victims, not all victims were Jews. A wide range of victim groups suffered under the Nazis, and millions were killed. These included anyone who did not fit in with the Nazis' idea of 'racial' superiority, or was opposed to them. Communists, Soviet prisoners of War, Jehovah's Witnesses, Poles (particularly intellectuals), members of the resistance, the Roma and Sinti peoples (gypsies) and Homosexuals were all interned in concentration camps, where slave labour, brutal conditions and the violence of the guards meant that life expectancy would rarely be more than a few months.
