The Third Wave (experiment)

The Third Wave was an experimental movement created by the American high school history teacher Ron Jones in 1967 to explain how the German population could have accepted the actions of the Nazi regime during the rise of the Third Reich and the Second World War. While Jones taught his students about Nazi Germany during his senior level Contemporary World History class, Jones found it difficult to explain how the German people could have accepted the actions of the Nazis.
