Uhtred of Bamburgh (sometimes Uchtred); died c. 1016), was ruler of Bamburgh and from 1006 to 1016 the ealdorman of Northumbria. He was the son of Waltheof I, ruler of Bamburgh (Bebbanburg), whose family the Eadwulfings had ruled the surrounding region for over a century. Uhtred's death by assassination was described in De obsessione Dunelmi and has been interpreted as beginning of a blood feud. Accomplishments In 995, according to Symeon of Durham, when the remains of St Cuthbert were transferred from Chester-le-Street to Durham, Uhtred went to Durham with his monks to clear the site of the new cathedral. The new cathedral was founded by Bishop Aldhun, and Uhtred married Aldhun's daughter, Ecgfrida, probably at about this time. From his marriage he received several estates that had belonged to the church. In 1006 King Malcolm II of Scotland invaded Northumbria and besieged the newly founded episcopal city of Durham. At that time the Danes were raiding southern England and the English King Ethelred was unable to send help to the Northumbrians. Ealdorman Waltheof was too old to fight and remained in his castle at Bamburgh. Ealdorman Ælfhelm of York also took no action. Uhtred, acting for his father, called together an army from Bernicia and Yorkshire and led it against the Scots, winning a decisive victory. Local women washed the severed heads of the Scots, receiving a payment of a cow for each, and the heads were fixed on stakes to Durham's walls. Ethelred rewarded Uhtred with the ealdormanry of Bamburgh even though his father was still alive. He also had Ælfhelm murdered, and allowed Uhtred to succeed Ælfhelm as ealdorman of York, thus uniting northern and southern Northumbria under the house of Bamburgh. It seems likely that Ethelred did not trust the Scandinavian population of southern Northumbria and wanted an Anglo-Saxon in power there. After receiving these honours Uhtred dismissed his wife, Ecgfrida, and married Sige, daughter of Styr, son of Ulf. Styr was a rich citizen of York. It appears that Uhtred was trying to make political allies amongst the Danes in Deira. With Sige, Uhtred had two children, Eadulf, later Eadulf III, and Gospatric. This Gospatric's grandson was the infamous Eadwulf Rus who murdered Bishop Walcher. In 1013 King Sweyn Forkbeard of Denmark invaded England, sailing up the Humber and Trent to the town of Gainsborough. Uhtred submitted to him there, as did all of the
