What is the X in X-mas?
king of the English from 946 to 955, who brought Northumbria permanently under English rule. Eadred was the son of the West Saxon king Edward the Elder (ruled 899-924) and Eadgifu, the half brother of King Athelstan (ruled 924-939), and the brother of King Edmund I (ruled 939-946). Upon Eadred's accession to power, the Northumbrians acknowledged his overlordship, but they soon proclaimed as their king Erik Bloodax, son of the Norwegian ruler Harald I Fairhair. In revenge Eadred ravaged all of Northumbria (948). The Northumbrians submitted to Eadred, but in 949 they accepted another Norse king, Olaf Sihtricson, as their ruler. They overthrew Olaf in 952 in favour of Erik Bloodax, who in turn was expelled and killed in 954. The Northumbrians then resumed their allegiance to Eadred.
