Gerhard "George" Lachmann Mosse was a German-American social and cultural historian, who emigrated from Nazi Germany to Great Britain and then to the United States. He was professor of history at the University of Iowa, the University of Wisconsin–Madison, and also in Israel, at the Hebrew University of Jerusalem. Best known for his studies of Nazism, he authored more than 25 books on topics as diverse as constitutional history, Protestant theology, and the history of masculinity. In 1966, he and Walter Laqueur founded The Journal of Contemporary History, which they co-edited.

The Völkisch movement was a German ethnic nationalist movement active from the late 19th century through the dissolution of the German Reich in 1945, with remnants in the Federal Republic of Germany afterwards. Erected on the idea of "blood and soil", inspired by the one-body-metaphor, and by the idea of naturally grown communities in unity, it was characterized by organicism, racialism, populism, agrarianism, romantic nationalism and – as a consequence of a growing exclusive and ethnic connotation – by antisemitism from the 1900s onward. Völkisch nationalists generally considered the Jews to be an "alien people" who belonged to a different Volk from the Germans.
