There were many witch hunts in the 17th Century across Britain, with dozens of well known witch hunters scouring the land. The most famous of which was Mathew Hopkins, the witch finder general who was based in Essex. Witches were heretics to Christianity, and the act of witchcraft was considered a crime so foul that all normal legal procedures were superseded, and because the Devil was not going to confess, it was necessary to gain a confession from the human involved. By all and any means necessary.
