Mary of Baux-Orange

Mary of Baux-Orange (died 1417) was suo jure Princess of Orange. She was the last holder of this title from the House of Baux.

Life Marie was the only child and therefore the sole heiress of Raymond V of Baux and Joan of Geneva. On 11 April 1386, she married John III, the son of Louis I, Lord of Chalon-Arlay and Margaret of Vienne. They had: Louis II, nicknamed Louis the Good (1390-1463)

Mary died in 1417 in Orange and was buried in L'église des Cordeliers at Lons-le-Saunier. Her husband died in 1418. Louis II inherited Chalon-Arlay from his father and Baux-Orange, including the Principality of Orange, from his mother. He claimed to have also inherited the County of Geneva via his grandmother, but lost a lengthy legal battle over this claim against the House of Savoy.
