In the shadowed corridors of twelfth-century French history stands a woman whose story has been largely forgotten—Eleanor of Vermandois (c. 1148–1213). Born into one of medieval Europe's most controversial families, Eleanor's life was marked by political intrigue, personal tragedy, and remarkable resilience as she navigated a world where powerful men controlled women's destinies.

If you're planning to read my popular, and currently free, historical novella Eleanor's Revenge, the first section of this post is spoiler-free, introducing Eleanor and her family background. Further down, after a clear spoiler warning, I delve into the full dramatic arc of her life.

A Scandalous Beginning

Eleanor's very existence was rooted in scandal. Her parents' marriage in 1142 triggered one of the most notorious affairs of the medieval period. Her father, Raoul I, Count of Vermandois, was the powerful seneschal of France and cousin to King Louis VII. Her mother, Petronilla of Aquitaine, was the younger sister of the legendary Eleanor of Aquitaine, who would become Queen of both France and England.

Their love story began at the French court around 1141, when Petronilla met the much older, married Raoul. With her sister's encouragement and the king's approval, Raoul secured an annulment from his first wife, Eleanor of Blois, on dubious grounds of consanguinity. Three compliant bishops—one of whom was Raoul's own brother—officiated at Raoul and Petronilla's wedding in early 1142.
