Werewolves

A human who can shapeshift into a wolf, often by curse.

Werewolves

In folklore, a werewolf (from Old English werwulf 'man-wolf'), or occasionally lycanthrope (from Ancient Greek λυκάνθρωπος 'wolf-human'), is an individual who can shapeshift into a wolf or therianthropic hybrid wolf–humanlike creature, either voluntarily or involuntarily due to a curse or other affliction. The werewolf is a widespread concept in European folklore, existing in many variants related by a common development of a Christian interpretation of underlying European folklore during the Middle Ages. Belief in werewolves developed in parallel with the belief in witches during the late Middle Ages and the early modern period, and the persecution of supposed werewolves emerged in what is now Switzerland in the early 15th century, spreading throughout Europe in the 16th, peaking in the 17th and subsiding by the 18th century.

Lore & Background

The werewolf motif has roots in Proto-Indo-European mythology, wherein lycanthropy is reconstructed as an aspect of the initiation of the kóryos warrior class, possibly involving a cult focused on dogs and wolves. In Classical antiquity, references appear in Ancient Greek literature: Herodotus wrote of the Neuri tribe who transformed into wolves annually; Pausanias related the story of King Lycaon of Arcadia, turned into a wolf for sacrificing a child; and Pliny the Elder recounted a tale of a man chosen by lot from the Anthus's clan who was transformed after being escorted to a marsh.

Reader's Guide

The werewolf is a central figure in European folklore, with beliefs spreading to the Western Hemisphere with colonialism from the early modern period. Persecution of supposed werewolves was an integral but marginal part of the witch-hunt phenomenon, with accusations of lycanthropy involved in only a small fraction of witchcraft trials. After the end of the witch trials, the werewolf became of interest in folklore studies and the emerging Gothic horror genre. Werewolf fiction developed in the 18th century out of the chapbook tradition, with premodern precedents in medieval romances such as Bisclavret and Guillaume de Palerme. In modern popular culture, the werewolf is a staple of horror and fantasy, with transformations often depicted as triggered by the full moon and transmitted by a bite or scratch from another werewolf.

Did You Know?

Common Misconceptions (Editorial)

Some people believe the full moon and transmission by bite or scratch are traditional folklore elements, but these details are specific to modern fiction, not the older European lore documented here. Another common misconception is that the term "lycanthropy" originally referred to mythological shapeshifting; however, ancient writers used it solely to describe a clinical delusion in which a patient imagined himself to be a wolf, not a literal transformation.

Why It Matters (Editorial)

The werewolf endures as a symbol of humanity’s struggle with its own primal instincts and the fear of losing control—themes that remain deeply relevant in modern horror and psychology. Its roots in ancient initiation rituals and early modern persecution also remind us how folklore can reflect real social anxieties, from witchcraft panics to the stigmatization of outsiders.

Frequently Asked Questions

What is a werewolf?

A werewolf is a human who can shift into a wolf or a wolf-human hybrid form. The transformation may be a deliberate act or the result of a curse and other supernatural afflictions.

How does a person become a werewolf?

In older folklore the change is typically forced on the individual by a curse or affliction rather than chosen freely. The popular idea that a bite or scratch transmits the condition is largely a modern-fiction addition.

Where does the word 'werewolf' come from?

It derives from Old English wer(e)wulf, built on Proto-Germanic *wira-wulfaz ('man-wolf') or *wazi-wulfaz ('wolf-clothed'). The Greek term lycanthrope simply means 'wolf-human.'

How did werewolf beliefs overlap with witchcraft?

During the late Middle Ages, Christian reinterpretation of older European folk traditions wove werewolf lore into the broader witchcraft narrative. That fusion is what shaped the werewolf image most people recognize in later European folklore.
