Heinrich Kramer's Malleus Maleficarum: The 15th-Century Treatise That Fueled European Witch Hunts

publication · 2026-04-17

Released in 1486, the Malleus Maleficarum emerged as a pivotal work for witch hunts across Europe between the mid-15th and mid-18th centuries. Authored by Heinrich Kramer, it was written following opposition from Helena Scheuberin. Kramer inaccurately credited Jacob Sprenger as a co-author and misappropriated Pope Innocent VIII's 1484 papal bull as an introduction. The text is structured in three sections, claiming the existence of witchcraft, outlining supposed practices, and recommending torture for obtaining confessions. Its deeply misogynistic themes contributed to women constituting 75-80% of the estimated 40,000-50,000 executions from around 100,000 trials. Critiques emerged from theologians at the Faculty of Cologne and later from figures such as Johann Weyer and Friedrich Spee von Langenfeld. By the 19th century, the book's impact had diminished.
