GUTHRUM (GODRUM) (d. 890), king of East Anglia, first appears in the English Annals in the year 875, when he is mentioned as one of three Danish kings who went with the host to Cambridge. He was probably engaged in the campaigns of the next three years, and after Alfred's victory at Edington in 878, Guthrum met the king at Aller in Somersetshire and was baptized there under the name of AEthelstan. He stayed there for twelve days and was greatly honoured by his godfather Alfred. In 890 Guthrum-^Ethelstan died: he is then spoken of as " se norSerna cyning" (probably) "the Norwegian king," referring to the ultimate origin of his family, and we are told that he was the first (Scandinavian) to settle East Anglia. Guthrum is perhaps to be identified with Gormr ( = Guthrum) hinn heimski or hinn riki of the Scandinavian sagas, the fosterfather of HorSaknutr, the father of Gorm the old. There is a treaty known as the peace of Alfred and Guthrum.
