Many historians, most notably Hugh Trevor-Roper, have said that the witch trials of the 16th and 17th century were a result of the religious struggles of the period. During this time, both the Catholic and Protestant Churches wanted to stamp out what they saw as heresy. The trial of the Samlesbury witches is perhaps one clear example of that trend; it has been described as "largely a piece of anti-Catholic propaganda". A trial would show that Lancashire, a wild and lawless area, was being cleared not only of witches but also of "popish plotters", that is, Catholics.
