There are many self-reflective passages where Anne laments being picked on by the adults in the annex, wondering if she will live up to the expectations they have for her, hoping she can reach her goals. There is a thread of hope apparent even in her most depressing writings. I think these are the parts I think teens find most relate-able because all teens want to achieve things, please their parents, and find hope in their moments of despair.
Nazi Germany maintained concentration camps (German: Konzentrationslager, KZ or KL) throughout the territories it controlled before and during the Second World War. The first Nazi camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control of the police by Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring. Used to hold and torture political opponents and union organizers, the camps initially held around 45,000 prisoners. In 1933–1939, before the onset of war, most prisoners consisted of German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans.
