Osberht

Osberht (died 21 March 867) was king of Northumbria in the middle of the 9th century. Sources on Northumbrian history in this period are limited. Osberht's descent is not known and the dating of his reign is problematic. Chronicles Osberht became king after Æthelred son of Eanred was murdered. The date of Æthelred's death is not certain, but is generally placed in 848. However, Symeon of Durham writes that "Ethelred the son of Eanred reigned nine years. When he was slain Osbryht held the kingdom for thirteen years" and states that 854 was "the fifth year of the rule of Osbert, the successor of Ethelred, who had been put to death". Little is known of Osberht's reign. Symeon states that "Osbert had dared with sacrilegious hand to wrest from that church Wercewurde and Tillemuthe". The Historia de Sancto Cuthberto dates the seizure of these lands to the year before Osberht's death. Osberht was replaced as king by Ælla. While Ælla is described in most sources as a tyrant, and not a rightful king, one source states that he was Osberht's brother. The Great Heathen Army marched on Northumbria in the late summer of 866, seizing York on 21 November 866. Symeon of Durham, the Anglo-Saxon Chronicle, Asser, and Æthelweard all recount substantially the same version of events in varying detail. Symeon's Historia Regum Anglorum gives this account of the battle on 21 March 867 where Osberht and Ælla met their deaths at the hands of the Vikings:
