Witchcraft, Necromancy, Politics - Eleanor Cobham's 1441 Trial

Evening Talk
£10
21 October 2026
5.30pm

Eleanor Cobham faced trial in 1441 for plotting against Henry VI with occult methods. Explore the crime, the people and the places.

The trial of Eleanor Cobham and her co-conspirators for occult crimes is a window onto several aspects of late medieval culture.

Eleanor Cobham (c. 1400 - 1452), second wife of Humphrey, duke of Gloucester, was put on trial in 1441. Eleanor was accused along with three other people, Thomas Southwell, Roger Bolingbroke and Margery Jourdemayne, of plotting to harm the King, Henry VI, by occult methods. Humphrey was the king's uncle and next-in-line to the throne to the childless Henry, who struggled with periods of severe mental incapacitation throughout his long reign, and so the potential political consequences were extreme.

Dr Joanne Edge will introduce the crime, and discuss the changing contexts of magic and its relation to politics in the century before the witch trials. You'll also discover how astrology, necromancy and witchcraft all linked together in this period. The talk will also situate the crime in the geography of London: it is where Eleanor was arrested, where the accused were held before trial, and where co-accused Roger Bolingbroke and Margery Jourdemayne were executed.
