Antisemitic disinformation was a hallmark of the Nazi regime, from its early rise in 1933. Access to information can make the difference between life and death, especially for the Jews of Europe during World War II. German occupiers attempted to – and largely succeeded at – controlling the flow of information through newspapers, radio, and the spread of false rumors. When witnesses and fugitives returned to ghettos and told their stories about the death camps, few believed what they heard; Nazi propaganda fueled these doubts. This lecture will explore the methods Nazis used in their attempts to control their citizens during the Holocaust, and how this history might shed light on our current information environment.
