king of Northumbria (c.863–7 or, possibly, his reign was confined to 867). He was the last independent English king of Northumbria. Though probably not of royal birth, he sought to usurp power from his predecessor Osberht. Danish armies took York in November 866. Ælle and Osberht united in an effort to regain the city on 21 March 867. They penetrated the walls, but both were then killed.
