The Spanish Inquisition is probably the most infamous example in which torture was used to extract information regarding allegations of heresy. In early modern times under certain conditions, torture was used in England. For example, the confession of Marc Smeaton at the trial of Anne Boleyn was presented in written form only, either to hide from the court that Smeaton had been tortured on the rack for four hours, or because Thomas Cromwell was worried that he would recant his confession if cross-examined. When Guy Fawkes was arrested for his role in the Gunpowder Plot of 1605 he was tortured until he revealed all he knew about the plot. This was not so much to extract a confession, which was not needed to prove his guilt, but to extract from him the names of his fellow conspirators. By this time torture was not routine in England and a special warrant from King James I was needed before he could be tortured. The wording of the warrant shows some concerns for humanitarian considerations; the severity of the methods of interrogation were to be increased gradually until the interrogators were sure that Fawkes had told all he knew. In the end this did not help Fawkes much as he was broken on the only rack in England, which was in the Tower of London. Torture was abolished in England around 1640 (except "peine forte et dure", whose aim was to force a defendant not to confess but to plead, which was abolished in 1772).
