The Bury St Edmunds witch trials were a series of trials conducted intermittently between the years 1599 and 1694 in the town of Bury St Edmunds in Suffolk, England.
Two specific trials in 1645 and 1662 became historically well known. The 1645 trial "facilitated" by the Witchfinder General saw 18 people executed in one day. The judgment by the future Lord Chief Justice of England and Wales, Sir Matthew Hale in the 1662 trial acted as a powerful influence on the continuing persecution of witches in England and similar persecutions in the American Colonies.[1]
