Mary of Burgundy, Duchess of Savoy

Mary of Burgundy (French: Marie de Bourgogne; 1386–1428) was a Duchess of Savoy by her marriage to Amadeus VIII of Savoy, who was later known as Antipope Felix V.

Life
Mary was born in 1386, most likely in September, in Dijon, France. She was the eighth of the nine children of Philip the Bold, Duke of Burgundy, and his wife Margaret III, Countess of Flanders.

From her birth, Mary's father intended her to marry Amadeus VIII of Savoy, son of Amadeus VII, Count of Savoy and Bonne of Berry. Their marriage was contracted in the year of her birth, on 11 November 1386 in Sluis, Zeeland; they married by proxy 30 October 1393 in Chalon-sur-Saône and in person at Arras in May 1401, when Mary was around 15 years old. However, she did not arrive in Savoy until she was 17, in September 1403.

In 1416, Sigismund, Holy Roman Emperor elevated Amadeus from Count to Duke of Savoy. Mary duly became Duchess. From then onwards Dukes ruled over Savoy.

The couple were married for thirty-six years before Mary died in the beginning of October 1428 at Chateau of Thonon-les-Bains. She is buried in the Abbey of Hautecombe.
