Ealdred (died c. 933) was a ruler of Bamburgh, at least part of the former kingdom of Bernicia in northern Northumbria, in the early tenth century. He was the son of Eadwulf. Background Ealdred's father, Eadwulf, called "king of the Saxons of the North" by the Annals of Ulster, but only actor (possibly representing 'reeve') of Bamburgh by the chronicler Æthelweard, died in 913. Eadwulf may have also been ruler of all of Northumbria following Eowils and Halfdan who were killed at Tettenhall circa 910. The twelfth-century tract De Northumbria post Britannos describes Ealdred's father Eadwulf as the grandson of Ælla of Northumbria (d. 867), via a daughter of the latter, Æthelthryth (it does not name Eadwulf's father). Life Upon his father's death in 913, Ealdred succeeded him. The Historia de Sancto Cuthberto states that Ealdred "was a friend of King Edward the Elder, as his father had been a favourite of King Alfred the Great". Seemingly in the 910s, according to the same source, Ealdred was driven from at least some of his lands by Ragnall ua Ímair. The Historia states that Ealdred sought refuge with Constantín mac Áeda, the king of Scotland, and that the two fought Ragnall at the Battle of Corbridge, dated by the Annals of Ulster and the Chronicle of the Kings of Alba to 918. The battle appears to have been indecisive and Ragnall remained the master of southern Northumbria, former Deira. However, if Ealdred was indeed "driven from his lands" then his regaining control of northern Northumbria was a decided benefit resulting from the battle. In 924 Ealdred submitted to Edward the Elder, and on 12 July 927 he was one of the northern rulers who submitted to Edward's son King Æthelstan at Eamont Bridge. Ealdred's submission added Northumbria to Æthelstan's kingdom and is generally seen as the date of the foundation of the Kingdom of England. Death Ealdred was a witness to several of Æthelstan's charters issued in southern England in 931 or 932, but he was not recorded thereafter. The Annals of Clonmacnoise record in 934 that "Adulf m'Etulfe king of the North Saxons died", and this may be the only notice of Ealdred's death, however, it is usually seen as a notice of a brother's death. Family Ealdred may have been Eadwulf's oldest son and the one who succeeded his father upon his death in 913. Historian Benjamin Hudson, writing
