Allison Balfour, alleged Scottish witch

The 1594 trial of alleged witch Allison Balfour or Margaret Balfour is one of the most frequently cited Scottish witchcraft cases. Balfour lived in the Orkney Islands of Scotland in the area of Stenness. At that time in Scotland, the Scottish Witchcraft Act 1563 had made a conviction for witchcraft punishable by death.

Patrick Stewart, 2nd Earl of Orkney, known as Black Patie, had control of Orkney in 1594 at the time of Balfour's trial. Patie was convinced that his younger brothers, especially John Stewart, Earl of Carrick, were plotting to kill him. Patie discovered poison in the possession of one of John's servants, Thomas Paplay, who after being tortured for eleven days confessed and implicated Balfour among his co-conspirators.

Although Paplay retracted his confession just before his execution, Balfour and her family were transported to Kirkwall, where they were tortured until a confession was extracted. Balfour was tried, found guilty of witchcraft, and sentenced to death. Just as Paplay had done, Balfour retracted her confession immediately before her execution on 16 December 1594, publicly proclaiming her innocence and detailing the tortures carried out on her and members of her family. She was executed at Gallow Ha' in Kirkwall on 16 December 1594.
