Robert I, Duke of Burgundy

Robert I the Old (1011–1076) was the third son of King Robert II of France and Constance of Arles. After rebelling against Henry I in 1031 with his mother's support, he received the Duchy of Burgundy in 1032, founding the ducal House of Burgundy.

His long reign was marked by violence: he plundered Church lands around Autun and Dijon and the abbey of Saint-Germain at Auxerre. In 1048 he repudiated his wife Helie of Semur and killed her father Lord Dalmas with his own hands.

Both his sons, Hugh and Henry, died before him. On his death in 1076 he was therefore succeeded by his grandson Hugh I.
