Witchcraft is the practice of magic and craft to shape events, to heal, protect, harm, or divine, expressed through charms, herbal lore, ritual, and the working of will. But the word carries at least three distinct meanings that must be kept apart. In its oldest and broadest sense it names the folk magic and cunning craft found across cultures: the everyday work of village charmers, healers, and "cunning folk" who used spells, herbs, and simples for practical ends, a largely benign and ubiquitous feature of pre-modern life. In a second sense, the one at the heart of the European witch-hunts of roughly 1450-1750, "witchcraft" was a demonological construction: the imagined crime of maleficium worked through a pact with the Devil, for which perhaps tens of thousands of people, overwhelmingly women, were tried and executed on the basis of a theory that modern historians regard as a lethal fantasy rather than a description of any real sect.
In a third and modern sense, "witchcraft" (or the Craft) names a living religion: Wicca, developed in mid-twentieth-century England and expanded since, and the broader modern Pagan witchcraft movement, which reclaim the word for a nature-venerating, magic-practising spirituality with no connection to the Devil of the witch-hunt imagination. Understanding witchcraft thus requires distinguishing the anthropological reality of folk magic, the historical tragedy of the witch persecutions and the false beliefs that drove them, and the contemporary religions that have taken the name as their own.
