Constance of Castile

The official reason for her husband's annulment from Eleanor of Aquitaine had been that he was too close a relative of Eleanor for the marriage to be legal by Church standards; however, he was even more closely related to Constance. They were second cousins through William I, Count of Burgundy.

Constance died giving birth to her second child. Desperate for a son, her husband remarried a mere five weeks after her death.

Constance was buried in the Basilica of Saint-Denis, Paris.

Constance had two children:

1. Margaret, 1157–1197, who married first Henry the Young King of England,^[4] and then Béla III of Hungary^[5]
2. Alys, 1160–1220, who married William IV of Ponthieu^[6]
