The Malleus Maleficarum, usually translated as the Hammer of Witches, is the best known treatise purporting to be about witchcraft. It was written by the German Catholic clergyman Heinrich Kramer and first published in the German city of Speyer in 1486. Some describe it as the compendium of literature in demonology of the 15th century. Kramer blamed women for his own lust and presented his views as the Church's position.

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.
