In 2012, a year-long programme of events in Lancaster and the surrounding area will mark the 400th anniversary of the trial and execution of the first group of Lancashire Witches. A second trial occurred in 1634 and although pardoned, the accused were re-imprisoned in Lancaster Castle. The case of the Lancashire Witches and their supposed crimes interwove fact and fiction, local hostilities and more exotic ideas of witches’ sabbats that were usually associated with continental witchcraft. They became a cause célèbre, like the witches of Trier and Fulda (Germany), Torsåker (Sweden) and Salem (North America). This interdisciplinary conference uses the Lancashire witches as a focal point to engage with wider questions about witchcraft: its definitions as maleficium (evil doing) or demonology in trials, the various traditions of witchcraft across centuries and continents, and the ways in which contemporary practice engages with these.
