The seeds of World War II were planted when Adolf Hitler, the demagogic leader of the Nazi Party, was named chancellor of Germany in 1933 (see timeline slideshow, below). Almost overnight, he turned a weak but democratic government into a totalitarian state.
Hitler began embedding the idea of a “master race” into the national psyche and spreading the sentiment that Germans, or “Aryans,” were genetically superior and non-Aryans were “subhuman.” Hitler had an animus toward Jews, whom he falsely blamed for Germany’s loss in World War I. He barred them from certain professions and government jobs, forbade them from using public spaces, and unleashed violence against them. On November 9, 1938—later known as Kristallnacht, or Night of Broken Glass—Nazis torched synagogues in Germany and Austria, looted Jewish businesses, and killed at least 90 Jews.
Beginning in September 1939, Hitler, seeking to vastly expand German territory, invaded Poland—and later France, Belgium, the Netherlands, and eventually most of Eastern Europe and parts of the Soviet Union. The Nazis deported Jews and those they deemed to be political opponents to concentration camps such as Auschwitz, where, beginning in 1943, people were murdered in gas chambers or deployed as slave laborers for the German war machine. The Nazis and their collaborators murdered 6 million Jews.
