Overview
Constance of Burgundy (8 May 1046 – 1093) was the daughter of Duke Robert I of Burgundy and Helie de Semur-en-Brionnais. She was Queen of Castile and León by her marriage to Alfonso VI of León and Castile. She was the granddaughter of King Robert II of France, the second monarch of the French Capetian dynasty. She was the mother of Urraca of León, who succeeded her father in both Castile and León.
Life
In 1065, Constance married her first husband, Hugh II, Count of Chalon. They were married for fourteen years until Hugh's death in 1079, they had no children.
In late 1079, Constance remarried to Alfonso VI of León and Castile. The marriage appears to have been orchestrated via the Cluniac connections at Alfonso's court. He had previously been married to Agnes of Aquitaine, whom he had either divorced or had been widowed by. The marriage of Constance and Alfonso initially faced papal opposition, apparently due to a kinship between Constance and Agnes.
Constance and Alfonso had several children but only one of these lived to adulthood:
Urraca (b. April 1079 – March 8, 1126) Queen of Castile and León in her own right. Married firstly to Raymond of Burgundy. Married secondly to Alfonso the Battler, no issue.
