Robert I Capet (1011 - March 21, 1076) was duke of Burgundy between 1032 to his death. Robert was son of King Robert II of France and brother of Henry I.
In 1025, with the death of his eldest brother Hugh Magnus, he and Henry rebelled against their father and defeated him, forcing him back to Paris. 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, Queen Constance d'Arles. Peace was only achieved when Robert was given Burgundy (1032).
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 burlged the abbey of St-Germain at Auxerre. In 1055, he repudiated his wife, Helie of Semur, and assassinated her brother Joceran and murdered her father, his father-in-law, Lord Dalmace I of Semur, with his own hands. 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."
His first son, Hugh, died in battle at a young age and his second son, Henry, also predeceased him. He was succeeded by Henry's eldest son, his grandson, Hugh I.
He married his first wife, Helie of Semur, about 1033, and repudiated her in 1055. Robert and Helie had five children:
1. Hugh (1034-1059), killed in battle
2. Henry (1035-ca.1074)
3. Robert (1040-1113), poisoned
4. Simon (1045-1087)
5. Constance (1046-1093), married Alfonso VI of Castile
* From his second wife, Ermengarde of Anjou, daughter of Fulk III of Anjou, he had one daughter:
1. Hildegard (c.1056-1104), married Duke William VIII of Aquitaine
Robert married Helie (Hedwig) de Semur, daughter of Dalmace I Count Of Semur and Aremburge de Vergy, in 1038 in France. (Helie (Hedwig) de Semur was born in 1016 in Sémur, France and died on 28 Apr 1055.)
Robert next married Ermengarde, Countess Of Anjou Countess of Gâtinais, daughter of Foulques III "Le Noir" d'Anjou Count of Anjou and Hildegarde d'Anjou Countess of Anjou, in 1055 in France. (Ermengarde, Countess Of Anjou Countess of Gâtinais was born in 1018 in Anjou, France and died between 24 Mar 1076 and 27 Mar 1076 in Anjou, France.)
