Werwulf (old English)

In folklore, a werewolf is an individual that can shapeshift into a wolf (or, especially in modern film, a therianthropic hybrid wolf-like creature), either purposely or after being placed under a curse or affliction (often a bite or the occasional scratch from another werewolf) with the transformations occurring on the night of a full moon.

The werewolf is a widespread concept in European folklore, existing in many variants, which are related by a common development of a Christian interpretation of underlying European folklore developed during the medieval period. From the early modern period, werewolf beliefs also spread to the New World with colonialism.

Belief in werewolves developed in parallel to the belief in witches, in the course of the Late Middle Ages and the Early Modern period. Like the witchcraft trials as a whole, the trial of supposed werewolves emerged in what is now Switzerland in the early 15th century and spread throughout Europe in the 16th, peaking in the 17th and subsiding by the 18th century.The persecution of werewolves and the associated folklore is an integral part of the "witch-hunt" phenomenon, albeit a marginal one, accusations of lycanthropy being involved in only a small fraction of witchcraft trials.During the early period, accusations of lycanthropy (transformation into a wolf) were mixed with accusations of wolf-riding or wolf-charming.
