Marie de Nemours, originally known as Marie d'Orléans-Longueville (1625–1707), was the reigning Princess of Neuchâtel from 1694 to 1707. After the death of her brother Jean Louis Charles d'Orléans, Duke of Longueville in 1694 she succeeded him as sovereign Princess of Neuchâtel, although she remained a prominent member of the French royal court. From her reign to her death she was the last living member of the House of Valois through a cadet line.

Biography

Marie was the daughter of Henri II d'Orléans, duc de Longueville and his first wife, Louise de Bourbon. At an early age she was involved in the first Fronde, of which her father and stepmother, Anne Geneviève de Bourbon, were leaders. She married Henri II, Duke of Nemours in 1657. When he died in 1659, leaving her childless, the rest of her life was mainly spent in contesting her inheritance with her stepmother. Her Savoyard nieces included Marie Jeanne, Duchess of Savoy and Marie Françoise, Queen of Portugal.

The Dukes of Longueville had acquired the principality of Neuchâtel through marriage to Johanna of Hachberg-Sausenberg. After the death of her brother Jean-Louis-Charles d'Orléans in 1694, she succeeded him as Princess of Neuchâtel.

Legacy

Marie left some interesting memoirs, published by C. B. Petitot in the Collection complete des memoires (1819–1829).
