Gilbert Duke of Burgundy
count of Chalon, Autun, Troyes, Avallon and Dijon, and duke of Burgundy between 952 and 956.
He ruled Burgundy jure uxoris, his wife Ermengarde being of the family of Richard the Justiciar. By her he had two daughters: Adelais and Liutgarde. Gilbert never managed to maintain the independence of the duchy in the struggles for power of 10th century France. In 955, he became a vassal of Hugh the Great, count of Paris and married his oldest daughter, Lieutgard, to Hugh's son Otto of Paris
