4. Jeff: In many instances, the term “concentration camp” becomes a catch all for the entirety of the camp system in the Nazi regime and the impression is that the majority of the camps had gas chambers and crematoria. By focusing on precision of language, we can help students (and others) understand that while there were many concentration camps, there were six extermination camps that focused on the annihilation of the Jewish population.

5. Karel - One of the groups that were perpetrators were teenagers in Hitler Youth that were influenced by the Nazi Regime. This photograph is part of the special exhibition entitled “Some Were Neighbors.” This photograph was chosen to demonstrate the variety of participants during the events of the Holocaust. It wasn’t just the Nazis and Jews. This included people from many walks of life - teachers, police, neighbors, businessmen, professors and many more.

—Operating in Western Belorussia (Belarus) between 1942 and 1944, the Bielski partisan group was one of the most significant Jewish resistance efforts against Nazi Germany during World War II.
—While its members did fight against the Germans and their collaborators, the Bielski group leaders emphasized providing a safe haven for Jews, particularly women, children, and elderly persons who managed to flee into the forests.
