or EADRIC, STREONA (d. 1017), ealdorman of the Mercians, was a man of ignoble birth who was advanced to high dignity through the favour of the English king !Ethelred II. In 1007 he became ealdorman of the Mercians, and subsequently married !Ethelred's daughter Eadgyth. In the struggle between the English and the Danes he appears in the character of an archtraitor. When 'Ethelred in 1009 proposed a great attack on the Danes, Edric dissuaded him from carrying it into effect. Again, on the invasion of England by Canute in 1015 Edric deserted Edmund Ironside and joined him. After the battle of Otford he returned to Edmund, but only by his treachery at the battle of Assandun to secure the utter defeat of the national cause. When peace was at length made, Canute restored to Edric the earldom of Mercia; but at Christmas 1017, fearing further treachery, he had him slain - "very rightly" says the Saxon Chronicle.
