Witches, werewolves, vampires, shapeshifters and many many more. Witches date back to centuries ago along with the legends of other mythical creatures.

Witchcraft traditionally means the use of magic or supernatural powers to harm others. A practitioner is a witch. In medieval and early modern Europe, where the term originated, accused witches were usually women who were believed to have used malevolent magic against their own community, and often to have communed with evil beings. It was thought witchcraft could be thwarted by protective magic or counter-magic, which could be provided by cunning folk or folk healers. Suspected witches were also intimidated, banished, attacked or killed. Often they would be formally prosecuted and punished, if found guilty or simply believed to be guilty. European witch-hunts and witch trials in the early modern period led to tens of thousands of executions. In some regions, many of those accused of witchcraft were folk healers or midwives. European belief in witchcraft gradually dwindled during and after the Age of Enlightenment.

Contemporary cultures that believe in magic and the supernatural often believe in witchcraft. Anthropologists have applied the term "witchcraft" to similar beliefs and occult practices described by many non-European cultures, and cultures that have adopted the English language will often call these practices "witchcraft", as well. As with the cunning-folk in Europe, Indigenous communities that believe in the existence of witchcraft define witches as the opposite of their healers and medicine people, who are sought out for protection against witchcraft. Modern witch-hunting takes place in parts of Africa and Asia.

A theory that witchcraft was a survival of a European pagan religion (the witch-cult hypothesis) gained popularity in the early 20th century, but has been discredited. A newer theory is that the idea of "witchcraft" developed to explain strange misfortune, similar to ideas such as the evil eye. In contemporary Western culture, most notably since the growth of Wicca from the 1950s, some modern pagans and followers of New Age belief systems may self-identify as "witches", and use the term "witchcraft" for their self-help, healing or divination rituals. Others avoid the term due to its negative connotations.

Near East beliefs

The belief in sorcery and its practice seem to have been widespread in the ancient Near East and Nile Valley. It played a conspicuous role in the cultures of ancient Egypt and in Babylonia. The latter tradition included an Akkadian anti-witchcraft ritual, the Maqlû. A section from the Code of Hammurabi (about 2000 BC) prescribes:

"If a man has put a spell upon another man and it is not justified, he upon whom the spell is laid shall go to the holy river; into the holy river shall he plunge. If the holy river overcome him and he is drowned, the man who put the spell upon him shall take possession of his house. If the holy river declares him innocent and he remains unharmed the man who laid the spell shall be put to death. He that plunged into the river shall take possession of the house of him who laid the spell upon him."

According to the New Advent Catholic Encyclopedia:

In the Holy Scripture references to sorcery are frequent, and the strong condemnations of such practices found there do not seem to be based so much upon the supposition of fraud as upon the abomination of the magic in itself.

The King James Version uses the words witch, witchcraft, and witchcrafts to translate the Masoretic כָּשַׁף‎ kāsháf (Hebrew pronunciation: [kɔˈʃaf]) and קֶסֶם‎ (qésem); these same English terms are used to translate φαρμακεία pharmakeia in the Greek New Testament. Verses such as Deuteronomy 18:11–12 and Exodus 22:18 ("Thou shalt not suffer a witch to live") thus provided scriptural justification for Christian witch hunters in the early modern period (see Christian views on magic).

The precise meaning of the Hebrew כָּשַׁף‎, usually translated as witch or sorceress, is uncertain. In the Septuagint, it was translated as pharmakeía or pharmakous. In the 16th century, Reginald Scot, a prominent critic of the witch trials, translated כָּשַׁף‎, φαρμακεία, and the Vulgate's Latin equivalent veneficos as all meaning 'poisoner', and on this basis, claimed that witch was an incorrect translation and poisoners were intended. His theory still holds some currency, but is not widely accepted, and in Daniel 2:2 כָּשַׁף‎ is listed alongside other magic practitioners who could interpret dreams: magicians, astrologers, and Chaldeans. Suggested derivations of כָּשַׁף‎ include 'mutterer' (from a single root) or herb user (as a compound word formed from the roots kash, meaning 'herb', and hapaleh, meaning 'using'). The Greek φαρμακεία literally means 'herbalist' or one who uses or administers drugs, but it was used virtually synonymously with mageia and goeteia as a term for a sorcerer.

The Bible provides some evidence that these commandments against sorcery were enforced under the Hebrew kings:

And Saul disguised himself, and put on other raiment, and he went, and two men with him, and they came to the woman by night: and he said, I pray thee, divine unto me by the familiar spirit, and bring me him up, whom I shall name unto thee. And the woman said unto him, Behold, thou knowest what Saul hath done, how he hath cut off those that have familiar spirits, and the wizards, out of the land: wherefore then layest thou a snare for my life, to cause me to die?

Witches in fiction span a wide array of characterizations. They are typically, but not always, female, and generally depicted as either villains or heroines.

The classic fairy tale "Hansel and Gretel" presents an example of the "witch villain" figure. The story involves a cannibalistic witch that is eventually outwitted by the children she tries to eat and is burned to death in her own oven. "Snow White" depicts a murderous, tempting magician for its main antagonist. The witch is labeled an evil queen and meets her demise after being forced to dance in red-hot iron shoes. "The Six Swans" includes a step-mother who magically turns her step-children into swans out of spite and jealousy. In retaliation, the figure labeled as witch is eventually burned at the stake. Such examples within the Brothers Grimm's works demonstrate not only evidence of the figure of "witch villain" but also exhibits their punishment by injury or violent death. Other examples of villainous witches in literature include the White Witch from C. S. Lewis's The Lion, the Witch and the Wardrobe and the Grand High Witch from Roald Dahl's The Witches.

Living Alone, published in 1919, uses the "witch heroine" as an agent in support of female liberation. Stella Benson's novel surrounds the musings of a female witch who functions as an anarchic force in the lives of middle-class Londoners. Her non-harmful magic aims to "shake the most downtrodden women out of complacency and normality" to meet a state of liberation. The importance of such a heroine sheds light on the positive effects associated with magic and witchcraft, a change from the often brutalized and tortured illustrations found in early nineteenth century literature. Other examples of heroic witches in fictional literature include Glinda from The Wonderful Wizard of Oz (1900), Serafina Pekkala from His Dark Materials (1995–2000), and Hermione Granger from the Harry Potter series.
