3 'Malleus Maleficarum'

Witch hysteria really took hold in Europe during the mid-1400s, when many accused witches confessed, often under torture, to a variety of wicked behaviors. Within a century, witch hunts were common and most of the accused were executed by burning at the stake or hanging. Single women, widows and other women on the margins of society were especially targeted.

Between the years 1500 and 1660, up to 80,000 suspected witches were put to death in Europe. Around 80 percent of them were women thought to be in cahoots with the Devil and filled with lust. Germany had the highest witchcraft execution rate, while Ireland had the lowest.

The publication of "Malleus Maleficarum"—written by two well-respected German Dominicans in 1486—likely spurred witch mania to go viral. The book, usually translated as "The Hammer of Witches," was essentially a guide on how to identify, hunt and interrogate witches.

"Malleus Maleficarum" labeled witchcraft as heresy, and quickly became the authority for Protestants and Catholics trying to flush out witches living among them. For more than 100 years, the book sold more copies of any other book in Europe except the Bible.
