The ailing Fulbert, bishop of Chartres told a colleague that he could attend the ceremony "if he traveled slowly to Reims—but he was too frightened of the queen to go at all". Constance encouraged her sons to rebel, and they began attacking and pillaging the towns and castles belonging to their father. Her son Robert attacked Burgundy, the duchy he had been promised but had never received, and Henry seized Dreux. At last King Robert agreed to their demands and peace was made which lasted until the king's death. King Robert died on 20 July 1031. Soon afterwards Constance fell ill; she was also at odds with both her surviving sons. Constance seized her dower lands and refused to surrender them. Henry fled to Normandy, where he received aid, weapons and soldiers from his brother Robert. He returned to besiege his mother at Poissy but Constance escaped to Pontoise. She only surrendered when Henry began the siege of Le Puiset and swore to slaughter all the inhabitants. Constance died after passing out following a coughing fit on 28 July 1032 and was buried beside her husband Robert at Saint-Denis Basilica. Children Constance and Robert had six children: Advisa, Countess of Auxerre (–after 1063), married Count Renaud I of Nevers Hugh Magnus, co-king (–17 September 1026) Henri (17 May 1008 – 4 August 1060) Adela, Countess of Contenance (1009 – 8 January 1079), married (1) Duke Richard III of Normandy (2) Count Baldwin V of Flanders Robert I, Duke of Burgundy (1011–21 March 1076) Eudes (1013–1056) References Additional resources Jessee, W.
