Amy S. Kaufman and Paul B. Sturtevant examine the long, dark history of "The Devil's Historians"--people who manipulate and use myths about the medieval past to promote discrimination, oppression, and murder. Tracing the fetish for "medieval times" behind toxic ideologies like nationalism, antisemitism, Islamophobia, misogyny, and white supremacy from European imperialists right up to the present-day "alt-right," Kaufman and Sturtevant show us that the Middle Ages have been twisted for political purposes ever since they came to a close. The Devil's Historians also casts aside the myths of an oppressive, patriarchal medieval monoculture and reveals a medieval world you may not have learned in school: one that is diverse, thriving, courageous, and compelling, and far more complex than those who want to bring us back to the Middle Ages would have you believe.
