The "Samlesbury witches", three women from the Lancashire village of Samlesbury, England, are put on trial, accused of practicing witchcraft, one of the most famous witch trials in British history.

The Samlesbury witches were three women from the Lancashire village of Samlesbury – Jane Southworth, Jennet Bierley, and Ellen Bierley – accused by a 14-year-old girl, Grace Sowerbutts, of practising witchcraft. Their trial at Lancaster Assizes in England on 19 August 1612 was one in a series of witch trials held there over two days, among the most infamous in English history. The trials were unusual for England at that time in two respects: Thomas Potts, the clerk to the court, published the proceedings in his The Wonderfull Discoverie of Witches in the Countie of Lancaster; and the number of the accused found guilty and hanged was unusually high, ten at Lancaster and another at York. All three of the Samlesbury women were acquitted.

Lancashire is a ceremonial county in North West England. It is bordered by Cumbria to the north, North Yorkshire and West Yorkshire to the east, Greater Manchester and Merseyside to the south, and the Irish Sea to the west. The largest settlement is Preston, and the county town is the city of Lancaster.

Samlesbury is a village and civil parish in South Ribble, Lancashire, England. Samlesbury Hall, a historic house, is in the village, as is Samlesbury Aerodrome and a large modern brewery owned by Anheuser-Busch InBev. The population at the 2011 census was 1,206.

The Kingdom of England was a sovereign state on the island of Great Britain from the 10th century, when it was unified from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern periods.
