Witchcraft (also called witchery or spellcraft) broadly means the practice of, and belief in, magical skills and abilities that are able to be exercised by individuals and certain social groups. Witchcraft is a complex concept that varies culturally and societally; therefore, it is difficult to define with precision and cross-cultural assumptions about the meaning or significance of the term should be applied with caution. Witchcraft often occupies a religious, divinatory or medicinal role, and is often present within societies and groups whose cultural framework includes a magical world view.
The concept of witchcraft and the belief in its existence have existed throughout recorded history. They have been present or central at various times, and in many diverse forms, among cultures and religions worldwide, including both "primitive" and "highly advanced" cultures, and continue to have an important role in many cultures today. Scientifically, the existence of magical powers and witchcraft are generally believed to lack credence and to be unsupported by high quality experimental testing, although individual witchcraft practices and effects may be open to scientific explanation or explained via mentalism and psychology.
Historically, the predominant concept of witchcraft in the Western world derives from Old Testament laws against witchcraft, and entered the mainstream when belief in witchcraft gained Church approval in the Early Modern Period. It posits a theosophical conflict between good and evil, where witchcraft was generally evil and often associated with the Devil and Devil worship. This culminated in deaths, torture and scapegoating (casting blame for human misfortune), and many years of large scale witch-trials and witch hunts, especially in Protestant Europe, before largely ceasing during the European Age of Enlightenment. Christian views in the modern day are diverse and cover the gamut of views from intense belief and opposition (especially from Christian fundamentalists) to non-belief, and in some churches even approval. From the mid-20th century, witchcraft – sometimes called contemporary witchcraft to clearly distinguish it from older beliefs – became the name of a branch of modern paganism. It is most notably practiced in the Wiccan and modern witchcraft traditions, and no longer practices in secrecy.
