The document outlines the history of anti-Semitism in Europe leading up to and during the Holocaust. It discusses how Jews were historically discriminated against and scapegoated. In early 20th century Germany, Hitler blamed Jews for Germany's loss in WWI and pushed the ideology of Aryan racial supremacy. This led to the boycott of Jewish businesses in 1933 and the Nuremberg Laws stripping Jews of rights in 1935. Kristallnacht organized violence against Jews in 1938. During 1939-1945, Jews were isolated in ghettos and millions were deported to camps, where many were killed in gas chambers or by forced labor, until the camps were liberated by Allied forces by 1945.
