Jeanne Agnès Berthelot de Pléneuf

Jeanne Agnès Berthelot de Pléneuf, marquise de Prie (1698 – 7 October 1727), was a French noblewoman notable for her intriguing during the reign of Louis XV.


She was the daughter of the financier Étienne Berthelot de Pléneuf. At the age of fifteen she was married to Louis, marquis de Prie, and went with him to the court of Savoy at Turin, where he was ambassador.[1]

She was 21 when she returned to France, and was soon the declared mistress of Louis Henri, Duke of Bourbon. During his ministry (1723–1725) she was in several respects the real ruler of France, her most notable triumph being the marriage of Louis XV of France to Marie Leszczynska instead of to Mademoiselle de Vermandois, the younger sister of the Duc de Bourbon. But when, in 1725, she sought to have Bourbon's rival Fleury exiled, her ascendancy came to an end. After Fleury's recall and the banishment of Bourbon to Chantilly, Madame de Prie was exiled to Courbépine, where she committed suicide the next year.[1]

Charlotte Rampling played de Prie in the 1996 TV movie La dernière fête, titled in English The Fall of the Marquise de Prie.
