At the death of her father, in 1608, Marie became the Duchess of Montpensier in her own right; the Duchy was one of the oldest in France having been elevated from a County in 1539. Marie was a descendant of John II of France, of the House of Valois and of Saint Louis.
Because of the Montpensier fortune, of which Marie was the only heiress, and despite the aversion shown by Gaston toward this arranged marriage, Louis XIII and Richelieu were determined the marriage would take place.
The wedding ceremony was celebrated in Nantes, on 6 August 1626, in the presence of Louis XIII, his wife, Queen Anne of Austria, and Marie de' Medici, the Queen Mother. According to her daughter's biographer, Vita Sackville-West, quoting a member of her husband's household, A sadder wedding was never seen..[2]
From this union, the new ducal couple had one child:
Marie died on 4 June 1627 at the Palais du Louvre in Paris, at the age of twenty-one, shortly after the birth of her daughter who, as her only child, inherited her fortune and titles. She was buried at the Royal Basilica of Saint Denis, north of Paris.
In a will intended to disinherit her niece,[3] Anne Marie Louise d'Orléans, Marie's half-sister Marie de Lorraine,[4]) chose Charles François de Stainville as beneficiary in 1688; but on the urging of her heirs, the will was broken by the Parlement of Paris in 1689.[5][6]
After the death of her daughter, La Grande Mademoiselle, in 1693, Marie's fortune was handed over to Philippe de France, Louis XIV's younger and only brother.
