The relationship between the Reformation and the upsurge in trials for witchcraft that occurred at roughly the same time is complex. Increasing persecution for witchcraft actually began before the Reformation in the 1480s, but it became especially common about 1560, and the mania continued until roughly 1660. Both Protestants and Catholics tried and executed witches, with church officials and secular authorities acting together.

The heightened sense of God’s power and divine wrath in the Reformation era was an important factor in the witch-hunts, but so was a change in the idea of what a witch was. In the later Middle Ages, many educated Christian theologians, canon lawyers, and officials added a demonological component to this notion of what a witch was. For them, the essence of witchcraft was making a pact with the Devil. Witches were no longer simply people who used magical power to get what they wanted, but rather people used by the Devil to do what he wanted. Witchcraft was thus spiritualized, and witches became the ultimate heretics, enemies of God.

Scholars estimate that during the sixteenth and seventeenth centuries, between 100,000 and 200,000 people were officially tried for witchcraft and between 40,000 and 60,000 were executed. Though the gender balance varied widely in different parts of Europe, between 75 and 85 percent of those tried and executed were women. Ideas about women and the roles women actually played in society were thus important factors shaping the witch-hunts. Some demonologists expressed virulent misogyny, or hatred of women. Most people viewed women as weaker and so more likely to give in to an offer by the Devil. In both classical and Christian traditions, women were associated with nature, disorder, and the body, all of which were linked with the demonic. Women’s actual lack of power in society and gender norms about the use of violence meant that they were more likely to use scolding and cursing to get what they wanted instead of taking people to court or beating them up. Curses were generally expressed (as they often are today) in religious terms; “go to Hell” was calling on the powers of Satan.

Legal changes also played a role in causing, or at least allowing for, massive witch trials. One of these was a change from an accusatorial legal procedure to an inquisitorial procedure. In the former, a suspect knew the accusers and the charges they had brought, and an accuser could in turn be liable for trial if the charges were not proven. In the latter, legal authorities themselves brought the case. This change made people much more willing to accuse others because they never had to take personal responsibility for the accusation or face the accused person’s relatives. Inquisitorial procedure involved intense questioning of the suspect, often with torture.

Most witch trials began with a single accusation in a village or town. Individuals accused someone they knew of using magic to spoil food, make children ill, kill animals, raise a hailstorm, or do other types of harm. Tensions within families, households, and neighborhoods often played a role in these accusations. Women number very prominently among accusers and witnesses as well as among those accused of witchcraft because the actions witches were initially charged with, such as harming children or curdling milk, were generally part of women’s sphere. A woman also gained economic and social security by conforming to the standard of the good wife and mother and by confronting women who deviated from it.

Once a charge was made, the suspect was brought in for questioning. After the initial suspect had been questioned, and particularly if he or she had been tortured, the people who had been implicated were brought in for questioning. This might lead to a small hunt, involving from five to ten suspects, and it sometimes grew into a much larger hunt, which historians have called a “witch panic.” Panics were most common in the part of Europe that saw the most witch accusations in general: the Holy Roman Empire, Switzerland, and parts of France. Most of this area consisted of very small governmental units that were jealous of each other and, after the Reformation, were divided by religion. The rulers of these small territories often felt more threatened than did the monarchs of western Europe, and they saw persecuting witches as a way to demonstrate their piety and concern for order. Moreover, witch panics often occurred after some type of climatic disaster, such as an unusually cold and wet summer, and they came in waves.

In large-scale panics, a wider variety of suspects were taken in — wealthier people, children, a greater proportion of men. Mass panics tended to end when it became clear to legal authorities, or to the community itself, that the people being questioned or executed were not what they understood witches to be, or that the scope of the accusations was beyond belief.

As the seventeenth century ushered in new ideas about science and reason, many began to question whether witches could make pacts with the Devil or engage in the wild activities attributed to them. Doubts about whether secret denunciations were valid or whether torture would ever yield truthful confessions gradually spread among the same type of religious and legal authorities who had so vigorously persecuted witches. Prosecutions for witchcraft became less common and were gradually outlawed.
