Marie was born at the Bois de Vincennes and was the sixth of twelve children, eight of them including Marie lived to adulthood.
Marie was born at the Bois de Vincennes and was the sixth of twelve children, eight of them including Marie lived to adulthood.
Marie"s father was known to suffer from a hereditary mental illness. Marie entered the convent of Poissy on 8 September 1397, taking her vows as a nun on 26 May 1408. At the time Marie entered the convent the prioress was her great-aunt, Marie of Bourbon, who was the sister of the younger Marie"s paternal grandmother, Joanna of Bourbon.
Christine described a visit to Poissy in 1400 in her work "Le Livre du Dit de Poissy," where she was greeted "joyously and tenderly" by the seven-year-old Marie of Valois and the Prioress.
Christine also described Marie"s lodgings as befitting a royal princess. But she declined, emphasising that only the king (who was mentally unstable at this time) had the power to force her to take a husband, and she remained at the abbey.
In later years, she became prioress of the convent and lived out the rest of her life there. She died of the Black Death on 19 August 1438 at the Palais Royal in Paris and is buried at the convent.
She was a member of the House of Valois and became a nun.
