Robert I of Burgundy, known as Robert the Old and "Tete-Hardi", was Duke of Burgundy from 1032 to his death.
Background
Robert was son of King Robert II of France and brother of Henry I of France. In 1031, after the death of his father the king, Robert participated in a rebellion against his brother, in which he was supported by his mother, Constance of Arles.
Career
Throughout his reign, he was little more than a robber baron who had no control over his own vassals, whose estates he often plundered, especially those of the Church. He seized the income of the diocese of Autun and the wine of the canons of Dijon. He burgled the abbey of Street-Germain at Auxerre.
In that same year, the bishop of Langres, Harduoin, refused to dedicate the church of Sennecy so as not "to be exposed to the violence of the duke."
Robert and Helie had five children:
Hugh (1034–1059), killed in battle
Henry (1035–ca1074).
Robert (1040–1113), poisoned. Married Violante of Sicily, daughter of Roger I of Sicily
Simon (1045–1087)
Constance (1046–1093), married Alfonso VI of León and Castile
Hildegarde (c1056–1104), married William VIII of Aquitaine.
