谁嫁给了Arthur III, Duke of Brittany？

Arthur III (Breton: Arzhur), more commonly known as Arthur de Richemont (24 August 1393 – 26 December 1458), was briefly Duke of Brittany from 1457 until his death. He is noted primarily, however, for his role as a leading military commander during the Hundred Years' War. Although Richemont briefly sided with the English once, he otherwise remained firmly committed to the House of Valois. He fought alongside Joan of Arc, and was appointed Constable of France. His military and administrative reforms in the French state were an important factor in assuring the final defeat of the English in the Hundred Years' War.

The name Richemont reflects the fact that he inherited the English title of Earl of Richmond, which was held by previous dukes of Brittany, but his tenure was never recognized by the English crown. At the very end of his life he became Duke of Brittany and Count of Montfort after inheriting those titles upon the death of his nephew Peter II. Richemont had no legitimate issue and was succeeded in the duchy by his other nephew, Francis II.

Catherine of Luxembourg-Saint-Pol (died 1492), was a Duchess consort of Brittany, married to Arthur III, Duke of Brittany. She was a daughter of Peter of Luxembourg, Count of Saint-Pol and Margherita del Balzo.

Catherine’s marriage to Arthur III took place on 2 July 1445. In December 1445 she went to Nantes, where her husband organized wedding celebrations in her honor. Then she lived in Parthenay and travelled only in 1457 with her husband again to Brittany, because his nephew, the duke Peter II, had fallen ill. After Peter’s death (22 September 1457) Arthur III became new Duke and therefore his wife Catherine briefly Duchess consort of Brittany, but Arthur already died on 26 December 1458 at Nantes at the age of 65 years. His marriage with Catherine had remained childless. Catherine lived as widow a secluded life, probably died in March 1492 and was buried in the Carthusian monastery of Nantes, which she had finished.

Margaret of Nevers (French: Marguerite; December 1393 – February 1442), also known as Margaret of Burgundy, was Dauphine of France and Duchess of Guyenne as the daughter-in-law of King Charles VI of France. A pawn in the dynastic struggles between her family and in-laws during the Hundred Years' War, Margaret was regarded as the future Queen of France at two separate times, as a result of her two marriages: first to the Dauphin and second to the Duke of Brittany.
