Who married Robert, Count of Clermont?

Robert of Clermont (1256 – 7 February 1317) was a French prince du sang who was created Count of Clermont in 1268. He was the sixth and last son of King Louis IX (Saint Louis) and Margaret of Provence.

Although he played a minor role in his lifetime due to a head injury which left him handicapped at a young age, he had an important dynastic position as the founder of the House of Bourbon, to which he passed the rights to the throne of France from his father when all male-line branches descended from his elder brothers died out in 1589, nine generations after him.

Beatrice of Burgundy (1257 – 1 October 1310) was ruling Lady of Bourbon from 1288 to 1310, and, through her mother, heiress of all Bourbon estates.

She was the daughter of John of Burgundy (son of Hugh IV, Duke of Burgundy) and Agnes of Dampierre, Lady of Bourbon. In 1272 Beatrice married Robert, Count of Clermont and their eldest son Louis I, le Boiteux became the first Duke of Bourbon.
