In the early modern period, from about 1400 to 1775, about 100,000 people were prosecuted for witchcraft in Europe and British America. Between 40,000 and 60,000 were executed. The witch-hunts were particularly severe in parts of the Holy Roman Empire. Prosecutions for witchcraft reached a high point from 1560 to 1630, during the Counter-Reformation and the European wars of religion. Among the lower classes, accusations of witchcraft were usually made by neighbors, and women made formal accusations as much as men did. Magical healers or 'cunning folk' were sometimes prosecuted for witchcraft, but seem to have made up a minority of the accused. Roughly 80% of those convicted were women, most of them over the age of 40. In some regions, convicted witches were burnt at the stake.

Witchcraft, as most commonly understood in both historical and present-day communities, is the use of alleged supernatural powers of magic. A witch is a practitioner of witchcraft. Traditionally, "witchcraft" means the use of magic or supernatural powers to inflict harm or misfortune on others, and this remains the most common and widespread meaning. According to Encyclopedia Britannica, "Witchcraft thus defined exists more in the imagination of contemporaries than in any objective reality. Yet this stereotype has a long history and has constituted for many cultures a viable explanation of evil in the world". The belief in witchcraft has been found in a great number of societies worldwide. Anthropologists have applied the English term "witchcraft" to similar beliefs in occult practices in many different cultures, and societies that have adopted the English language have often internalised the term.
