Joanna of Flanders
Joanna of Flanders was involved in the War of the Breton Succession and was married to John of Montfort, who claimed the title of Duke of Brittany. During her husband's imprisonment, Joanna led military campaigns and organized the defense of the city of Hennebont to support his claim. Her leadership was crucial in maintaining her husband's claim during his captivity.
Joanna spent her later years in confinement in England, where she lived until her death in 1374. Her son, John IV, succeeded her efforts by continuing the family claim to the duchy.
