French royalty, queen consort of France and duchess regnant of Brittany. She was the eldest daughter of Louis XII of France and Anne of Brittany, as well as the first spouse of Francis I of France.
Queen Claude was named after Claudius of Besançon, a saint her mother had invoked during a pilgrimage so she could give birth to a living child.
In 1514, when her mother died, Claude became Duchess of Brittany; and on 18 May 1514, at Saint-Germain-en-Laye, she married Francis, Duke of Angoulême.
Claude, the pawn of so much dynastic maneuvering, was short in stature and afflicted with scoliosis, which gave her a hunched back. She was eclipsed at court by her mother-in-law, Louise of Savoy, and her sister-in-law, the literary Navarrese queen Margaret of Angoulême.
Claude and Francis I had seven children, two of whom lived past the age of thirty: Louise (19 August 1515 – 21 September 1517) – died young, engaged to Charles I of Spain almost from birth until death; Charlotte (23 October 1516 – 8 September 1524) – died young, engaged to Charles I of Spain from 1518 until death; Francis (28 February 1518 – 10 August 1536), who succeeded Claude as Duke of Brittany, but died unmarried and childless; Henry (31 March 1519 – 10 July 1559), who succeeded Francis I as King of France and married Catherine de’ Medici, by whom he had issue; Madeleine (10 August 1520 – 2 July 1537), who married James V of Scotland and had no issue; Charles (22 January 1522 – 9 September 1545), who died unmarried and childless; and Margaret of France, Duchess of Berry (5 June 1523 – 14 September 1574), who married Emmanuel Philibert, Duke of Savoy, in 1559 and had issue.
Claude of France died on 20 July 1524.
