The Lancashire Witches is the only one of William Harrison Ainsworth's forty novels that has remained continuously in print since its first publication. It was serialised in the Sunday Times newspaper in 1848; a book edition appeared the following year, published by Henry Colburn. The novel is based on the true story of the Pendle witches, who were executed in 1612 for causing harm by witchcraft. Modern critics such as David Punter consider the book to be Ainsworth's best work. E. F. Bleiler rated the novel as "one of the major English novels about witchcraft".
Biographical background and publication
The subject of the Pendle witches was suggested to Ainsworth by antiquarian and long-time friend James Crossley, President of the Chetham Society. During 1846 and 1847 Ainsworth visited all of the major sites involved in the story, such as Pendle Hill and Malkin Tower, home of the Demdikes, one of the two families accused of witchcraft. He wrote the story in 1848, when it was serialised in the Sunday Times newspaper. On completion of the work, Ainsworth was paid £1,000 () and the copyright reverted to him.

As was common practice at the time, the novel was published in a three-volume set known as a triple decker. The first edition was produced by Henry Colburn in 1849, with the subtitle "A Romance of Pendle Forest". At £1 11s 6d, about the amount that a skilled worker could earn in a week, it was expensive. Routledge published an illustrated edition in 1854, reissued in 1878. The twelve full-page illustrations were by John Gilbert.

Plot
Ainsworth based his story largely on the official account of the Lancashire witch trials written by the clerk to the court, Thomas Potts, first published in 1613 under the title The Wonderfull Discoverie of Witches in the Countie of Lancaster. Potts himself makes an appearance in the book, as a "scheming and self-serving lawyer". The novel consists of four parts, each written as a third-person narrative.

Introduction
The ten chapters of the Introduction, subtitled "The Last Abbot of Whalley", are set against the backdrop of the 1536 Pilgrimage of Grace, an uprising by northern Catholics against the English Reformation instituted by King Henry VIII.
It is late November 1536. Eight men, prominent among them John Paslew, Abbot of Whalley and the self-styled Earl of Poverty, are gathered together by a beacon at the top of Pendle Hill. An uneasy armistice has been declared in the Pilgrimage, and beacons have been built on high ground to act as a renewed summons to arms should they ever be lit; that is the signal the eight men are waiting for.
As dusk approaches the abbot and his party become aware of a tall dark man accompanied by a black hound standing close by, whom one of the party recognises as Nicholas Demdike, husband of Bess Demdike, "an approved and notorious witch". Demdike starts to sing, mocking the abbot and foretelling of his execution, which so enrages the abbot that he orders one of his archers to loose a shot at him. But Demdike merely laughs before disappearing down the hill, only pausing about half-way down to trace a circle in the grass and repeat some incantation.
In the growing darkness a signal fire is seen on a neighbouring hill, then another and another. Excitedly the abbot lights the beacon on Pendle Hill and prepares to ride to Whalley Abbey, to organise his forces in preparation for joining the main body of the rebel army the following day. But before he can leave, Demdike appears before him, to warn the abbot that if he proceeds with his plan his life will be forfeit. Demdike claims that he can save the abbot however, on one condition: that he baptise Demdike's infant daughter. Meanwhile a party of Royalist soldiers is ascending the hill in search of the abbot and his men, but Demdike conjures up a torrent of water from the spot where he had earlier traced the circle, and most of the soldiers are carried to their deaths. But still the abbot refuses to acquiesce to Demdike's request for his daughter to be baptised.
